C. Time to apply.
1. Any person proposing a new discharge, shall submit an application at least 180 days before the date on which the discharge is to commence, unless permission for a later date has been granted by the board. Facilities proposing a new discharge of storm water associated with industrial activity shall submit an application 180 days before that facility commences industrial activity which may result in a discharge of storm water associated with that industrial activity. Different submittal dates may be required under the terms of applicable general permits. Persons proposing a new discharge are encouraged to submit their applications well in advance of the 90 or 180 day requirements to avoid delay. New discharges composed entirely of storm water, other than those dischargers identified in 9VAC25-31-120 A 1, shall apply for and obtain a permit according to the application requirements in 9VAC25-31-120 B.
2. All TWTDS whose sewage sludge use or disposal practices are regulated by 9VAC25-31-420 through 9VAC25-31-720 must submit permit applications according to the applicable schedule in subdivision 2 a or b of this subsection.
a. A TWTDS with a currently effective VPDES permit must submit a permit application at the time of its next VPDES permit renewal application. Such information must be submitted in accordance with subsection D of this section.
b. Any other TWTDS not addressed under subdivision 2 a of this subsection must submit the information listed in subdivisions 2 b (1) through (5) of this subsection to the department within one year after publication of a standard applicable to its sewage sludge use or disposal practice(s), using a form provided by the department. The board will determine when such TWTDS must submit a full permit application.
(1) The TWTDS's name, mailing address, location, and status as federal, state, private, public or other entity;
(2) The applicant's name, address, telephone number, and ownership status;
(3) A description of the sewage sludge use or disposal practices. Unless the sewage sludge meets the requirements of subdivision P 8 d of this section, the description must include the name and address of any facility where sewage sludge is sent for treatment or disposal and the location of any land application sites;
(4) Annual amount of sewage sludge generated, treated, used or disposed (estimated dry weight basis); and
(5) The most recent data the TWTDS may have on the quality of the sewage sludge.
c. Notwithstanding subdivision 2 a or b of this subsection, the board may require permit applications from any TWTDS at any time if the board determines that a permit is necessary to protect public health and the environment from any potential adverse effects that may occur from toxic pollutants in sewage sludge.
d. Any TWTDS that commences operations after promulgation of an applicable standard for sewage sludge use or disposal shall submit an application to the department at least 180 days prior to the date proposed for commencing operations.
D. Duty to reapply. All permittees with a currently effective permit shall submit a new application at least 180 days before the expiration date of the existing permit, unless permission for a later date has been granted by the board. The board shall not grant permission for applications to be submitted later than the expiration date of the existing permit.
E. Completeness.
1. The board shall not issue a permit before receiving a complete application for a permit except for VPDES general permits. An application for a permit is complete when the board receives an application form and any supplemental information which are completed to its satisfaction. The completeness of any application for a permit shall be judged independently of the status of any other permit application or permit for the same facility or activity.
2. No application for a VPDES permit to discharge sewage into or adjacent to state waters from a privately owned treatment works serving, or designed to serve, 50 or more residences shall be considered complete unless the applicant has provided the department with notification from the State Corporation Commission that the applicant is incorporated in the Commonwealth and is in compliance with all regulations and relevant orders of the State Corporation Commission.
3. No application for a new individual VPDES permit authorizing a new discharge of sewage, industrial wastes, or other wastes shall be considered complete unless it contains notification from the county, city, or town in which the discharge is to take place that the location and operation of the discharging facility are consistent with applicable ordinances adopted pursuant to Chapter 22 (§ 15.2-2200 et seq.) of Title 15.2 of the Code of Virginia. The county, city or town shall inform in writing the applicant and the board of the discharging facility's compliance or noncompliance not more than 30 days from receipt by the chief administrative officer, or his agent, of a request from the applicant. Should the county, city or town fail to provide such written notification within 30 days, the requirement for such notification is waived. The provisions of this subsection shall not apply to any discharge for which a valid VPDES permit had been issued prior to March 10, 2000.
4. A permit application shall not be considered complete if the board has waived application requirements under subsection J or P of this section and the EPA has disapproved the waiver application. If a waiver request has been submitted to the EPA more than 210 days prior to permit expiration and the EPA has not disapproved the waiver application 181 days prior to permit expiration, the permit application lacking the information subject to the waiver application shall be considered complete.
5. In accordance with § 62.1-44.19:3 A of the Code of Virginia, no application for a permit or variance to authorize the storage of sewage sludge shall be complete unless it contains certification from the governing body of the locality in which the sewage sludge is to be stored that the storage site is consistent with all applicable ordinances. The governing body shall confirm or deny consistency within 30 days of receiving a request for certification. If the governing body does not so respond, the site shall be deemed consistent.

A topographic map (or other map if a topographic map is unavailable) extending one mile beyond the property boundaries of the source, depicting the facility and each of its intake and discharge structures; each of its hazardous waste treatment, storage, or disposal facilities; each well where fluids from the facility are injected underground; and those wells, springs, other surface water bodies, and drinking water wells listed in public records or otherwise known to the applicant in the map area; and
8. A brief description of the nature of the business.
G. Application requirements for existing manufacturing, commercial, mining, and silvicultural dischargers. Existing manufacturing, commercial mining, and silvicultural dischargers applying for VPDES permits, except for those facilities subject to the requirements of 9VAC25-31-100 H, shall provide the following information to the department, using application forms provided by the department.
1. The latitude and longitude of each outfall to the nearest 15 seconds and the name of the receiving water.
2. A line drawing of the water flow through the facility with a water balance, showing operations contributing wastewater to the effluent and treatment units. Similar processes, operations, or production areas may be indicated as a single unit, labeled to correspond to the more detailed identification under subdivision 3 of this subsection. The water balance must show approximate average flows at intake and discharge points and between units, including treatment units. If a water balance cannot be determined (for example, for certain mining activities), the applicant may provide instead a pictorial description of the nature and amount of any sources of water and any collection and treatment measures.
3. A narrative identification of each type of process, operation, or production area which contributes wastewater to the effluent for each outfall, including process wastewater, cooling water, and storm water run-off; the average flow which each process contributes; and a description of the treatment the wastewater receives, including the ultimate disposal of any solid or fluid wastes other than by discharge. Processes, operations, or production areas may be described in general terms (for example, dye-making reactor, distillation tower). For a privately owned treatment works, this information shall include the identity of each user of the treatment works. The average flow of point sources composed of storm water may be estimated. The basis for the rainfall event and the method of estimation must be indicated.
4. If any of the discharges described in subdivision 3 of this subsection are intermittent or seasonal, a description of the frequency, duration and flow rate of each discharge occurrence (except for storm water run-off, spillage or leaks).
5. If an effluent guideline promulgated under § 304 of the CWA applies to the applicant and is expressed in terms of production (or other measure of operation), a reasonable measure of the applicant's actual production reported in the units used in the applicable effluent guideline. The reported measure must reflect the actual production of the facility.
6. If the applicant is subject to any present requirements or compliance schedules for construction, upgrading or operation of waste treatment equipment, an identification of the abatement requirement, a description of the abatement project, and a listing of the required and projected final compliance dates.
7. a. Information on the discharge of pollutants specified in this subdivision (except information on storm water discharges which is to be provided as specified in 9VAC25-31-120). When quantitative data for a pollutant are required, the applicant must collect a sample of effluent and analyze it for the pollutant in accordance with analytical methods approved under 40 CFR Part 136
(2005). When no analytical method is approved the applicant may use any suitable method but must provide a description of the method. When an applicant has two or more outfalls with substantially identical effluents, the board may allow the applicant to test only one outfall and report that the quantitative data also apply to the substantially identical outfalls. The requirements in e and f of this subdivision that an applicant must provide quantitative data for certain pollutants known or believed to be present do not apply to pollutants present in a discharge solely as the result of their presence in intake water; however, an applicant must report such pollutants as present. Grab samples must be used for pH, temperature, cyanide, total phenols, residual chlorine, oil and grease, fecal coliform, and fecal streptococcus. For all other pollutants, 24-hour composite samples must be used. However, a minimum of one grab sample may be taken for effluents from holding ponds or other impoundments with a retention period greater than 24 hours. In addition, for discharges other than storm water discharges, the board may waive composite sampling for any outfall for which the applicant demonstrates that the use of an automatic sampler is infeasible and that the minimum of four grab samples will be a representative sample of the effluent being discharged.b. For storm water discharges, all samples shall be collected from the discharge resulting from a storm event that is greater than 0.1 inch and at least 72 hours from the previously measurable (greater than 0.1 inch rainfall) storm event. Where feasible, the variance in the duration of the event and the total rainfall of the event should not exceed 50% from the average or median rainfall event in that area. For all applicants, a flow-weighted composite shall be taken for either the entire discharge or for the first three hours of the discharge. The flow-weighted composite sample for a storm water discharge may be taken with a continuous sampler or as a combination of a minimum of three sample aliquots taken in each hour of discharge for the entire discharge or for the first three hours of the discharge, with each aliquot being separated by a minimum period of 15 minutes (applicants submitting permit applications for storm water discharges under 9VAC25-31-120 C may collect flow-weighted composite samples using different protocols with respect to the time duration between the collection of sample aliquots, subject to the approval of the board). However, a minimum of one grab sample may be taken for storm water discharges from holding ponds or other impoundments with a retention period greater than 24 hours. For a flow-weighted composite sample, only one analysis of the composite of aliquots is required. For storm water discharge samples taken from discharges associated with industrial activities, quantitative data must be reported for the grab sample taken during the first 30 minutes (or as soon thereafter as practicable) of the discharge for all pollutants specified in 9VAC25-31-120 B 1. For all storm water permit applicants taking flow-weighted composites, quantitative data must be reported for all pollutants specified in 9VAC25-31-120 except pH, temperature, cyanide, total phenols, residual chlorine, oil and grease, fecal coliform, and fecal streptococcus. The board may allow or establish appropriate site-specific sampling procedures or requirements, including sampling locations, the season in which the sampling takes place, the minimum duration between the previous measurable storm event and the storm event sampled, the minimum or maximum level of precipitation required for an appropriate storm event, the form of precipitation sampled (snow melt or rain fall), protocols for collecting samples under 40 CFR Part 136
(2005), and additional time for submitting data on a case-by-case basis. An applicant is expected to know or have reason to believe that a pollutant is present in an effluent based on an evaluation of the expected use, production, or storage of the pollutant, or on any previous analyses for the pollutant. (For example, any pesticide manufactured by a facility may be expected to be present in contaminated storm water run-off from the facility.)c. Every applicant must report quantitative data for every outfall for the following pollutants:
Biochemical oxygen demand (BOD5)
Chemical oxygen demand
Total organic carbon
Total suspended solids
Ammonia (as N)
Temperature (both winter and summer)
pH
d. The board may waive the reporting requirements for individual point sources or for a particular industry category for one or more of the pollutants listed in subdivision 7 c of this subsection if the applicant has demonstrated that such a waiver is appropriate because information adequate to support issuance of a permit can be obtained with less stringent requirements.
e. Each applicant with processes in one or more primary industry category (see 40 CFR Part 122 Appendix A
(2005))) contributing to a discharge must report quantitative data for the following pollutants in each outfall containing process wastewater:(1) The organic toxic pollutants in the fractions designated in Table I of 40 CFR Part 122 Appendix D
(2005)for the applicant's industrial category or categories unless the applicant qualifies as a small business under subdivision 8 of this subsection. Table II of 40 CFR Part 122 Appendix D(2005)lists the organic toxic pollutants in each fraction. The fractions result from the sample preparation required by the analytical procedure which uses gas chromatography/mass spectrometry. A determination that an applicant falls within a particular industrial category for the purposes of selecting fractions for testing is not conclusive as to the applicant's inclusion in that category for any other purposes; and(2) The pollutants listed in Table III of 40 CFR Part 122 Appendix D
(2005)(the toxic metals, cyanide, and total phenols).f. (1) Each applicant must indicate whether it knows or has reason to believe that any of the pollutants in Table IV of 40 CFR Part 122 Appendix D
(2005)(certain conventional and nonconventional pollutants) is discharged from each outfall. If an applicable effluent limitations guideline either directly limits the pollutant or, by its express terms, indirectly limits the pollutant through limitations on an indicator, the applicant must report quantitative data. For every pollutant discharged which is not so limited in an effluent limitations guideline, the applicant must either report quantitative data or briefly describe the reasons the pollutant is expected to be discharged.(2) Each applicant must indicate whether it knows or has reason to believe that any of the pollutants listed in Table II or Table III of 40 CFR Part 122 Appendix D
(2005)(the toxic pollutants and total phenols) for which quantitative data are not otherwise required under subdivision 7 e of this subsection, is discharged from each outfall. For every pollutant expected to be discharged in concentrations of 10 ppb or greater the applicant must report quantitative data. For acrolein, acrylonitrile, 2,4 dinitrophenol, and 2-methyl-4,6 dinitrophenol, where any of these four pollutants are expected to be discharged in concentrations of 100 ppb or greater the applicant must report quantitative data. For every pollutant expected to be discharged in concentrations less than 10 ppb, or in the case of acrolein, acrylonitrile, 2,4 dinitrophenol, and 2-methyl-4,6 dinitrophenol, in concentrations less than 100 ppb, the applicant must either submit quantitative data or briefly describe the reasons the pollutant is expected to be discharged. An applicant qualifying as a small business under subdivision 8 of this subsection is not required to analyze for pollutants listed in Table II of 40 CFR Part 122 Appendix D(2005)(the organic toxic pollutants).g. Each applicant must indicate whether it knows or has reason to believe that any of the pollutants in Table V of 40 CFR Part 122 Appendix D
(2005)(certain hazardous substances and asbestos) are discharged from each outfall. For every pollutant expected to be discharged, the applicant must briefly describe the reasons the pollutant is expected to be discharged, and report any quantitative data it has for any pollutant.h. Each applicant must report qualitative data, generated using a screening procedure not calibrated with analytical standards, for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) if it:
(1) Uses or manufactures 2,4,5-trichlorophenoxy acetic acid (2,4,5,-T); 2-(2,4,5-trichlorophenoxy) propanoic acid (Silvex, 2,4,5,-TP); 2-(2,4,5-trichlorophenoxy) ethyl, 2,2-dichloropropionate (Erbon); O,O-dimethyl O-(2,4,5-trichlorophenyl) phosphorothioate (Ronnel); 2,4,5-trichlorophenol (TCP); or hexachlorophene (HCP); or
(2) Knows or has reason to believe that TCDD is or may be present in an effluent.
8. An applicant which qualifies as a small business under one of the following criteria is exempt from the requirements in subdivision 7 e (1) or 7 f (1) of this subsection to submit quantitative data for the pollutants listed in Table II of 40 CFR Part 122 Appendix D
(2005)(the organic toxic pollutants):a. For coal mines, a probable total annual production of less than 100,000 tons per year; or
b. For all other applicants, gross total annual sales averaging less than $100,000 per year (in second quarter 1980 dollars).
9. A listing of any toxic pollutant which the applicant currently uses or manufactures as an intermediate or final product or byproduct. The board may waive or modify this requirement for any applicant if the applicant demonstrates that it would be unduly burdensome to identify each toxic pollutant and the board has adequate information to issue the permit.
10. Reserved.
11. An identification of any biological toxicity tests which the applicant knows or has reason to believe have been made within the last three years on any of the applicant's discharges or on a receiving water in relation to a discharge.
12. If a contract laboratory or consulting firm performed any of the analyses required by subdivision 7 of this subsection, the identity of each laboratory or firm and the analyses performed.
13. In addition to the information reported on the application form, applicants shall provide to the board, at its request, such other information, including pertinent plans, specifications, maps and such other relevant information as may be required, in scope and details satisfactory to the board, as the board may reasonably require to assess the discharges of the facility and to determine whether to issue a VPDES permit. The additional information may include additional quantitative data and bioassays to assess the relative toxicity of discharges to aquatic life and requirements to determine the cause of the toxicity.
H. Application requirements for manufacturing, commercial, mining and silvicultural facilities which discharge only nonprocess wastewater. Except for storm water discharges, all manufacturing, commercial, mining and silvicultural dischargers applying for VPDES permits which discharge only nonprocess wastewater not regulated by an effluent limitations guideline or new source performance standard shall provide the following information to the department using application forms provided by the department:

An identification of cooling water additives (if any) that are used or expected to be used upon commencement of operations, along with their composition if existing composition is available;
4. a. Quantitative data for the pollutants or parameters listed below, unless testing is waived by the board. The quantitative data may be data collected over the past 365 days, if they remain representative of current operations, and must include maximum daily value, average daily value, and number of measurements taken. The applicant must collect and analyze samples in accordance with 40 CFR Part 136
(2005). Grab samples must be used for pH, temperature, oil and grease, total residual chlorine, and fecal coliform. For all other pollutants, 24-hour composite samples must be used. New dischargers must include estimates for the pollutants or parameters listed below instead of actual sampling data, along with the source of each estimate. All levels must be reported or estimated as concentration and as total mass, except for flow, pH, and temperature.(1) Biochemical oxygen demand (BOD5).
(2) Total suspended solids (TSS).
(3) Fecal coliform (if believed present or if sanitary waste is or will be discharged).
(4) Total residual chlorine (if chlorine is used).

b. The board may waive the testing and reporting requirements for any of the pollutants or flow listed in subdivision 4 a of this subsection if the applicant submits a request for such a waiver before or with his application which demonstrates that information adequate to support issuance of a permit can be obtained through less stringent requirements.
c. If the applicant is a new discharger, he must submit the information required in subdivision 4 a of this subsection by providing quantitative data in accordance with that section no later than two years after commencement of discharge. However, the applicant need not submit testing results which he has already performed and reported under the discharge monitoring requirements of his VPDES permit.
d. The requirements of subdivisions 4 a and 4 c of this subsection that an applicant must provide quantitative data or estimates of certain pollutants do not apply to pollutants present in a discharge solely as a result of their presence in intake water. However, an applicant must report such pollutants as present. Net credit may be provided for the presence of pollutants in intake water if the requirements of 9VAC25-31-230 G are met;
5. A description of the frequency of flow and duration of any seasonal or intermittent discharge (except for storm water run-off, leaks, or spills);

Permit applicants must submit all information available at the time of permit application. The information may be provided by referencing information previously submitted to the department. The board may waive any requirement of this subsection if it has access to substantially identical information. The board may also waive any requirement of this subsection that is not of material concern for a specific permit, if approved by the regional administrator. The waiver request to the regional administrator must include the board's justification for the waiver. A regional administrator's disapproval of the board's proposed waiver does not constitute final agency action but does provide notice to the board and permit applicant(s) that the EPA may object to any board-issued permit issued in the absence of the required information.

g. All existing data for pollutants specified in subdivisions 4 b through e of this subsection that is collected within 4-1/2 years of the application must be included in the pollutant data summary submitted by the applicant. If, however, the applicant samples for a specific pollutant on a monthly or more frequent basis, it is only necessary, for such pollutant, to summarize all data collected within one year of the application.
h. Applicants must collect samples of effluent and analyze such samples for pollutants in accordance with analytical methods approved under 40 CFR Part 136
(2005)unless an alternative is specified in the existing VPDES permit. Grab samples must be used for pH, temperature, cyanide, total phenols, residual chlorine, oil and grease, and fecal coliform.

a. A discharge with respect to which a permit has been issued prior to February 4, 1987;
b. A discharge associated with industrial activity; or
c. A discharge which either the board or the regional administrator determines to contribute to a violation of a water quality standard or is a significant contributor of pollutants to surface waters. This designation may include a discharge from any conveyance or system of conveyances used for collecting and conveying storm water run-off, except for those discharges from conveyances which do not require a permit under subdivision 2 of this subsection or agricultural storm water run-off which is exempted from the definition of point source.
2. The board may not require a permit for discharges of storm water run-off from mining operations or oil and gas exploration, production, processing or treatment operations, or transmission facilities, composed entirely of flows which are from conveyances or systems of conveyances (including but not limited to pipes, conduits, ditches, and channels) used for collecting and conveying precipitation run-off and which are not contaminated by contact with or that has not come into contact with, any overburden, raw material, intermediate products, finished product, by-product or waste products located on the site of such operations.
3. In addition to meeting the requirements of subsection B of this section, an operator of a storm water discharge associated with industrial activity which discharges through a large or medium municipal separate storm sewer system shall submit, to the operator of the municipal separate storm sewer system receiving the discharge no later than May 15, 1991, or 180 days prior to commencing such discharge: the name of the facility; a contact person and phone number; the location of the discharge; a description, including Standard Industrial Classification, which best reflects the principal products or services provided by each facility; and any existing VPDES permit number.
4. For storm water discharges associated with industrial activity from point sources which discharge through a nonmunicipal or nonpublicly owned separate storm sewer system, the board, in its discretion, may issue: a single VPDES permit, with each discharger a co-permittee to a permit issued to the operator of the portion of the system that discharges into surface waters; or, individual permits to each discharger of storm water associated with industrial activity through the nonmunicipal conveyance system.
a. All storm water discharges associated with industrial activity that discharge through a storm water discharge system that is not a municipal separate storm sewer must be covered by an individual permit, or a permit issued to the operator of the portion of the system that discharges to surface waters, with each discharger to the nonmunicipal conveyance a co-permittee to that permit.
b. Where there is more than one operator of a single system of such conveyances, all operators of storm water discharges associated with industrial activity must submit applications.
c. Any permit covering more than one operator shall identify the effluent limitations, or other permit conditions, if any, that apply to each operator.
5. Conveyances that discharge storm water run-off combined with municipal sewage are point sources that must obtain VPDES permits in accordance with the procedures of 9VAC25-31-100 and are not subject to the provisions of this section.
6. Whether a discharge from a municipal separate storm sewer is or is not subject to VPDES regulation shall have no bearing on whether the owner or operator of the discharge is eligible for funding under Title II, Title III or Title VI of the CWA.
7. a. On and after October 1, 1994, for discharges composed entirely of storm water, that are not required by subdivision 1 of this subsection to obtain a permit, operators shall be required to obtain a VPDES permit only if:
(1) The board or the EPA regional administrator determines that storm water controls are needed for the discharge based on wasteload allocations that are part of "total maximum daily loads" (TMDLs) that address the pollutant(s) of concern; or
(2) The board or the EPA regional administrator determines that the discharge, or category of discharges within a geographic area, contributes to a violation of a water quality standard or is a significant contributor of pollutants to surface waters.

1. Individual applications.
a. Except as provided in subdivision 1 b of this subsection, for any storm water discharge associated with industrial activity as defined in this chapter which is not authorized by a storm water general permit, a permit application made pursuant to subsection B of this section shall be submitted to the department by October 1, 1992;
b. For any storm water discharge associated with industrial activity from a facility that is owned or operated by a municipality with a population of less than 100,000 that is not authorized by a general or individual permit, other than an airport, powerplant, or uncontrolled sanitary landfill, permit applications must be submitted to the department by March 10, 2003;
2. A permit application shall be submitted to the department within 180 days of notice, unless permission for a later date is granted by the board, for:
a. A storm water discharge which either the board or the regional administrator, determines that the discharge contributes to a violation of a water quality standard or is a significant contributor of pollutants to surface waters; or
b. A storm water discharge subject to subdivision B 1 d of this section;
3. Facilities with existing VPDES permits for storm water discharges associated with industrial activity shall maintain existing permits. Facilities with permits for storm water discharges associated with industrial activity which expire on or after May 18, 1992, shall submit a new application in accordance with the requirements of 9VAC25-31-100 and 9VAC25-31-120 B (Form 1, Form 2F, and other applicable forms) 180 days before the expiration of such permits.
D. Petitions.
1. Any person may petition the board to require a VPDES permit for a discharge which is composed entirely of storm water which contributes to a violation of a water quality standard or is a significant contributor of pollutants to surface waters.
2. The board shall make a final determination on any petition received under this section within 90 days after receiving the petition.
E. Conditional exclusion for no exposure of industrial activities and materials to storm water. Discharges composed entirely of storm water are not storm water discharges associated with industrial activity if there is no exposure of industrial materials and activities to rain, snow, snowmelt or run-off and the discharger satisfies the conditions in subdivisions 1 through 4 of this subsection. No exposure means that all industrial materials and activities are protected by a storm resistant shelter to prevent exposure to rain, snow, snowmelt, and run-off. Industrial materials or activities include, but are not limited to, material handling equipment or activities, industrial machinery, raw materials, intermediate products, by-products, final products, or waste products. Material handling activities include the storage, loading and unloading, transportation, or conveyance of any raw material, intermediate product, final product or waste product.
1. To qualify for this exclusion, the operator of the discharge must:
a. Provide a storm resistant shelter to protect industrial materials and activities from exposure to rain, snow, snow melt, and run-off;
b. Complete and sign (according to 9VAC25-31-110) a certification that there are no discharges of storm water contaminated by exposure to industrial materials and activities from the entire facility, except as provided in subdivision 2 of this subsection;
c. Submit the signed certification to the department once every five years;
d. Allow the department to inspect the facility to determine compliance with the no exposure conditions;
e. Allow the department to make any no exposure inspection reports available to the public upon request; and
f. For facilities that discharge through an MS4, upon request, submit a copy of the certification of no exposure to the MS4 operator, as well as allow inspection and public reporting by the MS4 operator.
2. Storm resistant shelter is not required for:
a. Drums, barrels, tanks, and similar containers that are tightly sealed, provided those containers are not deteriorated and do not leak ("sealed" means banded or otherwise secured and without operational taps or valves);
b. Adequately maintained vehicles used in material handling; and
c. Final products, other than products that would be mobilized in storm water discharge (e.g., rock salt).
3. a. This conditional exclusion from the requirement for a VPDES permit is available on a facility-wide basis only, not for individual outfalls. If a facility has some discharges of storm water that would otherwise be no exposure discharges, individual permit requirements should be adjusted accordingly.
b. If circumstances change and industrial materials or activities become exposed to rain, snow, snow melt, or run-off, the conditions for this exclusion no longer apply. In such cases, the discharge becomes subject to enforcement for unpermitted discharge. Any conditionally exempt discharger who anticipates changes in circumstances should apply for and obtain permit authorization prior to the change of circumstances.
c. Notwithstanding the provisions of this subsection, the board retains the authority to require permit authorization (and deny this exclusion) upon making a determination that the discharge causes, has a reasonable potential to cause, or contributes to an instream excursion above an applicable water quality standard, including designated uses.
4. The no exposure certification requires the submission of the following information, at a minimum, to aid the board in determining if the facility qualifies for the no exposure exclusion:
a. The legal name, address and phone number of the discharger.
b. The facility name and address, the county name and the latitude and longitude where the facility is located.
c. Certification that indicates that none of the following materials or activities are, or will be in the foreseeable future, exposed to precipitation:
(1) Using, storing or cleaning industrial machinery or equipment, and areas where residuals from using, storing or cleaning industrial machinery or equipment remain and are exposed to storm water;
(2) Materials or residuals on the ground or in storm water inlets from spills/leaks;
(3) Materials or products from past industrial activity;
(4) Material handling equipment (except adequately maintained vehicles);
(5) Materials or products during loading/unloading or transporting activities;
(6) Materials or products stored outdoors (except final products intended for outside use, e.g., new cars, where exposure to storm water does not result in the discharge of pollutants);
(7) Materials contained in open, deteriorated or leaking storage drums, barrels, tanks, and similar containers;
(8) Materials or products handled/stored on roads or railways owned or maintained by the discharger;
(9) Waste material (except waste in covered, nonleaking containers, e.g., dumpsters);
(10) Application or disposal of process wastewater (unless otherwise permitted); and
(11) Particulate matter or visible deposits of residuals from roof stacks/vents not otherwise regulated, i.e., under an air quality control permit, and evident in the storm water outflow.
d. All no exposure certifications must include the following certification statement and be signed in accordance with the signatory requirements of 9VAC25-31-110: "I certify under penalty of law that I have read and understand the eligibility requirements for claiming a condition of no exposure and obtaining an exclusion from VPDES storm water permitting; and that there are no discharges of storm water contaminated by exposure to industrial activities or materials from the industrial facility identified in this document (except as allowed under 9VAC25-31-120 E 2). I understand that I am obligated to submit a no exposure certification form once every five years to the Department of Environmental Quality and, if requested, to the operator of the local MS4 into which this facility discharges (where applicable). I understand that I must allow the department, or MS4 operator where the discharge is into the local MS4, to perform inspections to confirm the condition of no exposure and to make such inspection reports publicly available upon request. I understand that I must obtain coverage under a VPDES permit prior to any point source discharge of storm water associated with industrial activity from the facility. I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted. Based upon my inquiry of the person or persons who manage the system, or those persons directly involved in gathering the information, the information submitted is to the best of my knowledge and belief true, accurate and complete. I am aware there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations."
9VAC25-31-130. Concentrated animal feeding operations.
A. Permit requirement for CAFOs.
1. Concentrated animal feeding operations as defined in 9VAC25-31-10 or designated in accordance with subsection B of this section are point sources that require VPDES permits for discharges or proposed discharges. Once an operation is defined as a CAFO, the VPDES requirements for CAFOs apply with respect to all animals in confinement at the operation and all manure, litter and process wastewater generated by those animals or the production of those animals, regardless of the type of animal.
2. Two or more animal feeding operations under common ownership are considered, for the purposes of this chapter, to be a single animal feeding operation if they adjoin each other or if they use a common area or system for the disposal of wastes.
B. Case-by-case designations. The board may designate any animal feeding operation as a concentrated animal feeding operation upon determining that it is a significant contributor of pollution to surface waters.
1. In making this designation the board shall consider the following factors:
a. The size of the animal feeding operation and the amount of wastes reaching surface waters;
b. The location of the animal feeding operation relative to surface waters;
c. The means of conveyance of animal wastes and process wastewaters into surface waters;
d. The slope, vegetation, rainfall, and other factors affecting the likelihood or frequency of discharge of animal wastes and process wastewaters into surface waters; and
e. Other relevant factors.
2. No animal feeding operation with less than the numbers of animals set forth in the definition of Medium CAFO in this regulation shall be designated as a concentrated animal feeding operation unless:
a. Pollutants are discharged into surface waters through a manmade ditch, flushing system, or other similar manmade device; or
b. Pollutants are discharged directly into surface waters which originate outside of the facility and pass over, across, or through the facility or otherwise come into direct contact with the animals confined in the operation.
3. A permit application shall not be required from a concentrated animal feeding operation designated under this subsection until the board has conducted an on-site inspection of the operation and determined that the operation should and could be regulated under the VPDES permit program.
C. Who must seek coverage under a VPDES permit?
1. The owners or operators of a CAFO shall seek coverage under a VPDES permit if the CAFO discharges or proposes to discharge. A CAFO proposes to discharge if it is designed, constructed, operated, or maintained such that a discharge will occur. Specifically, the CAFO owner or operator shall either apply for an individual VPDES permit or apply for coverage under a VPDES general permit. If there is no VPDES general permit available to the CAFO, the CAFO owner or operator shall submit an application for an individual permit to the board.
2. Exception. An owner or operator of a Large CAFO does not need to seek coverage under a VPDES permit if the owner or operator certifies to the board that the CAFO does not discharge or propose to discharge manure, litter or process wastewater.
3. Information to submit with permit application. A permit application for an individual permit must include the information specified in 9VAC25-31-100 I. A notice of intent for a general permit must include the information specified in 9VAC25-31-100 I and 9VAC25-31-170.
4. Land application discharges from a CAFO are subject to VPDES requirements. The discharge of manure, litter or process wastewater to surface waters from a CAFO as the result of the application of that manure, litter or process wastewater by the CAFO to land areas under its control is a discharge from that CAFO subject to VPDES requirements, except where it is an agricultural storm water discharge as provided in 33 USC § 1362(14). For purposes of this subdivision, where the manure, litter or process wastewater has been applied in accordance with a nutrient management plan approved by the Department of Conservation and Recreation and in accordance with site specific nutrient management practices that ensure appropriate agricultural utilization of the nutrients in the manure, litter or process wastewater, as specified in subdivisions E 1 f through i of 9VAC25-31-200, a precipitation-related discharge of manure, litter or process wastewater from land areas under the control of a CAFO is an agricultural storm water discharge.
a. For unpermitted Large CAFOs, a precipitation-related discharge of manure, litter, or process wastewater from land areas under the control of a CAFO shall be considered an agricultural stormwater discharge only where the manure, litter, or process wastewater has been land applied in accordance with site-specific nutrient management practices that ensure appropriate agricultural utilization of the nutrients in the manure, litter, or process wastewater, as specified in subdivisions E 1 f through i of 9VAC25-31-200.
b. Unpermitted Large CAFOs shall maintain documentation specified in subdivision E 1 i of 9VAC25-31-200 either on site or at a nearby office, or otherwise make such documentation readily available to department staff upon request.
5. No discharge certification option.
a. The owner or operator of a CAFO that meets the eligibility criteria in subdivision 5 b of this subsection may certify to the board that the CAFO does not discharge or propose to discharge. A CAFO owner or operator who certifies that the CAFO does not discharge or propose to discharge is not required to seek coverage under a VPDES permit pursuant to subdivision 1 of this subsection, provided that the CAFO is designed, constructed, operated, and maintained in accordance with the requirements of subdivisions 5 b and c of this subsection, and subject to the limitations in subdivision 5 d of this subsection.
b. Eligibility criteria. In order to certify that a CAFO does not discharge or propose to discharge, the owner or operator of a CAFO shall document, based on an objective assessment of the conditions at the CAFO, that the CAFO is designed, constructed, operated, and maintained in a manner such that the CAFO will not discharge, as follows:
(1) The CAFO's production area is designed, constructed, operated, and maintained so as not to discharge. The CAFO shall maintain documentation that demonstrates that:
(a) Any open manure storage structures are designed, constructed, operated, and maintained to achieve no discharge based on a technical evaluation in accordance with the elements of the technical evaluation set forth in 40 CFR 412.46(a)(1)(i) through (viii)
(2009);(b) Any part of the CAFO's production area that is not addressed by subdivision 5 b (1) (a) of this subsection is designed, constructed, operated, and maintained such that there will be no discharge of manure, litter, or process wastewater; and
(c) The CAFO implements the additional measures set forth in 40 CFR 412.37(a) and (b)
(2009);(2) The CAFO has developed and is implementing an up-to-date nutrient management plan to ensure no discharge from the CAFO, including from all land application areas under the control of the CAFO, that addresses, at a minimum, the following:
(a) The elements of subdivisions E 1 a through i of 9VAC25-31-200 and 40 CFR 412.37(c)
(2009); and(b) All site-specific operation and maintenance practices necessary to ensure no discharge, including any practices or conditions established by a technical evaluation pursuant to subdivision 5 b (1) (a) of this subsection; and
(3) The CAFO shall maintain documentation required by subdivision 5 b of this subsection either on site or at a nearby office, or otherwise make such documentation readily available to the department staff upon request.
c. Submission to the board. In order to certify that a CAFO does not discharge or propose to discharge, the CAFO owner or operator shall complete and submit to the board, by certified mail or equivalent method of documentation, a certification that includes, at a minimum, the following information:
(1) The legal name, address, and phone number of the CAFO owner or operator (see 9VAC25-31-100 B);
(2) The CAFO name and address, the county name, and the latitude and longitude where the CAFO is located;
(3) A statement that describes the basis for the CAFO's certification that it satisfies the eligibility requirements identified in subdivision 5 b of this subsection;
(4) The following certification statement: "I certify under penalty of law that I am the owner or operator of a concentrated animal feeding operation (CAFO), identified as [Name of CAFO], and that said CAFO meets the requirements of subdivision 5 of this subsection. I have read and understand the eligibility requirements of subdivision 5 b of this subsection for certifying that a CAFO does not discharge or propose to discharge and further certify that this CAFO satisfies the eligibility requirements. As part of this certification, I am including the information required by subdivision 5 c of this subsection. I also understand the conditions set forth in subdivisions 5 d, e and f of this subsection regarding loss and withdrawal of certification. I certify under penalty of law that this document and all other documents required for this certification were prepared under my direction or supervision and that qualified personnel properly gathered and evaluated the information submitted. Based upon my inquiry of the person or persons directly involved in gathering and evaluating the information, the information submitted is to the best of my knowledge and belief true, accurate and complete. I am aware there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations."; and
(5) The certification shall be signed in accordance with the signatory requirements of 9VAC25-31-110.
d. Term of certification. A certification that meets the requirements of subdivisions 5 b and c of this subsection shall become effective on the date it is submitted, unless the board establishes an effective date of up to 30 days after the date of submission. Certification will remain in effect for five years or until the certification is no longer valid or is withdrawn, whichever occurs first. A certification is no longer valid when a discharge has occurred or when the CAFO ceases to meet the eligibility criteria in subdivision 5 b of this subsection.
e. Withdrawal of certification.
(1) At any time, a CAFO may withdraw its certification by notifying the board by certified mail or equivalent method of documentation. A certification is withdrawn on the date the notification is submitted to the board. The CAFO does not need to specify any reason for the withdrawal in its notification to the board.
(2) If a certification becomes invalid in accordance with subdivision 5 d of this subsection, the CAFO shall withdraw its certification within three days of the date on which the CAFO becomes aware that the certification is invalid. Once a CAFO's certification is no longer valid, the CAFO is subject to the requirement in subdivision 1 of this subsection to seek permit coverage if it discharges or proposes to discharge.
f. Recertification. A previously certified CAFO that does not discharge or propose to discharge may recertify in accordance with subdivision 5 of this subsection, except that where the CAFO has discharged, the CAFO may only recertify if the following additional conditions are met:
(1) The CAFO had a valid certification at the time of the discharge;
(2) The owner or operator satisfies the eligibility criteria of subdivision 5 b of this subsection, including any necessary modifications to the CAFO's design, construction, operation, and/or maintenance to permanently address the cause of the discharge and ensure that no discharge from this cause occurs in the future;
(3) The CAFO has not previously recertified after a discharge from the same cause;
(4) The owner or operator submits to the board for review the following documentation: a description of the discharge, including the date, time, cause, duration, and approximate volume of the discharge, and a detailed explanation of the steps taken by the CAFO to permanently address the cause of the discharge in addition to submitting a certification in accordance with subdivision 5 c of this subsection; and
(5) Notwithstanding subdivision 5 d of this subsection, a recertification that meets the requirements of subdivisions 5 f (3) and (4) of this subsection shall only become effective 30 days from the date of submission of the recertification documentation.
g. Effect of certification.
(1) An unpermitted CAFO certified in accordance with subdivision 5 of this subsection is presumed not to propose to discharge. If such a CAFO does discharge, it is not in violation of the requirement that CAFOs that propose to discharge seek permit coverage pursuant to subdivisions 1 and 6 of this subsection, with respect to that discharge. In all instances, the discharge of a pollutant without a permit is a violation of the Clean Water Act § 301(a) prohibition against unauthorized discharges from point sources.
(2) In any enforcement proceeding for failure to seek permit coverage under subdivisions 1 and 6 of this subsection that is related to a discharge from an unpermitted CAFO, the burden is on the CAFO to establish that it did not propose to discharge prior to the discharge when the CAFO either did not submit certification documentation as provided in subdivision 5 c or 5 f (4) of this subsection within at least five years prior to the discharge, or withdrew its certification in accordance with subdivision 5 e of this subsection. Design, construction, operation, and maintenance in accordance with the criteria of subdivision 5 b of this subsection satisfies this burden.
6. When a CAFO must seek coverage under a VPDES permit.
a. Operations defined as CAFOs prior to April 14, 2003. For operations that are defined as CAFOs under regulations that are in effect prior to April 14, 2003, the owner or operator must have or seek to obtain coverage under a VPDES permit as of April 14, 2003, and comply with all applicable VPDES requirements, including the duty to maintain permit coverage in accordance with subdivision 7 of this subsection.
b. Operations defined as CAFOs as of April 14, 2003, that were not defined as CAFOs prior to that date. For all CAFOs, the owner or operator of the CAFO must seek to obtain coverage under a VPDES permit by February 27, 2009.
c. Operations that become defined as CAFOs after April 14, 2003, but that are not new sources. For newly constructed AFOs and CAFOs that make changes to their operations that result in becoming defined as CAFOs for the first time, after April 14, 2003, but are not new sources, the owner or operator must seek to obtain coverage under a VPDES permit, as follows:
(1) For newly constructed operations not subject to effluent limitation guidelines, 180 days prior to the time the CAFO commences operation;
(2) For other operations (e.g., resulting from an increase in the number of animals), as soon as possible, but no later than 90 days after becoming defined as a CAFO; or
(3) If an operational change that makes the operation a CAFO would not have made it a CAFO prior to April 14, 2003, the operation has at least until February 27, 2009, or 90 days after becoming defined as a CAFO, whichever is later.
d. New sources. New sources must seek to obtain coverage under a permit at least 180 days prior to the time the CAFO commences operation.
e. Operations that are designated CAFOs. For operations designated as a CAFO in accordance with subsection B of this section, the owner or operator must seek to obtain coverage under a VPDES permit no later than 90 days after receiving notice of the designation.
7. Duty to maintain permit coverage. No later than 180 days before the expiration of the permit, the permittee shall submit an application to renew its permit, in accordance with 9VAC25-31-100. However, the permittee need not continue to seek continued permit coverage or reapply for a permit if:
a. The facility has ceased operation or is no longer a CAFO; and
b. The permittee has demonstrated to the satisfaction of the board that the CAFO will not discharge or propose to discharge upon expiration of the permit.
8. Procedures for CAFOs seeking coverage under a general permit. CAFO owners or operators shall submit a registration statement when seeking authorization to discharge under a general permit in accordance with subsection B of 9VAC25-31-170. The board will review registration statements submitted by CAFO owners or operators to ensure that the registration statement includes the information required by subsection I of 9VAC25-31-100, including a nutrient management plan that meets the requirements of subsection E of 9VAC25-31-200 and applicable effluent limitations and standards, including those specified in 40 CFR Part 412
(2009). When additional information is necessary to complete the registration statement or clarify, modify, or supplement previously submitted material, the board may request such information from the owner or operator. If the board makes a preliminary determination that the registration statement meets the requirements of subsection I of 9VAC25-31-100 and subsection E of 9VAC25-31-200, the board will notify the public of the board's proposal to grant coverage under the permit to the CAFO and make available for public review and comment the registration statement submitted by the CAFO, including the CAFO's nutrient management plan, and the draft terms of the nutrient management plan to be incorporated into the permit. The process for submitting public comments and public hearing requests, and the public hearing process if a request for a public hearing is granted, shall follow the procedures applicable to draft permits set forth in 9VAC25-31-300, 9VAC25-31-310 and 40 CFR 124.13(2009). The board may establish, either by regulation or in the general permit, an appropriate period of time for the public to comment and request a public hearing that differs from the time period specified in 9VAC25-31-290. The board's response to significant comments received during the comment period is governed by 9VAC25-31-320, and, if necessary, the board will require the CAFO owner or operator to revise the nutrient management plan in order to be granted permit coverage. When the board authorizes coverage for the CAFO owner or operator under the general permit, the terms of the nutrient management plan shall become incorporated as terms and conditions of the permit for the CAFO. The board will notify the CAFO owner or operator and inform the public that coverage has been authorized and of the terms of the nutrient management plan incorporated as terms and conditions of the permit applicable to the CAFO.9. Changes to a nutrient management plan. Any permit issued to a CAFO shall require the following procedures to apply when a CAFO owner or operator makes changes to the CAFO's nutrient management plan previously submitted to the board:
a. The CAFO owner or operator shall provide the board with the most current version of the CAFO's nutrient management plan and identify changes from the previous version, except that the results of calculations made in accordance with the requirements of subdivisions E 5 a (2) and E 5 b (4) of 9VAC25-31-200 are not subject to the requirements of subdivision 9 of this subsection.
b. The board will review the revised nutrient management plan to ensure that it meets the requirements of this section and applicable effluent limitations and standards, including those specified in 40 CFR Part 412
(2009), and will determine whether the changes to the nutrient management plan necessitate revision to the terms of the nutrient management plan incorporated into the permit issued to the CAFO. If revision to the terms of the nutrient management plan is not necessary, the board will notify the CAFO owner or operator and upon such notification the CAFO may implement the revised nutrient management plan. If revision to the terms of the nutrient management plan is necessary, the board will determine whether such changes are substantial changes as described in subdivision 9 c of this subsection.(1) If the board determines that the changes to the terms of the nutrient management plan are not substantial, the board will make the revised nutrient management plan publicly available and include it in the permit record, revise the terms of the nutrient management plan incorporated into the permit, and notify the owner or operator and inform the public of any changes to the terms of the nutrient management plan that are incorporated into the permit.
(2) If the board determines that the changes to the terms of the nutrient management plan are substantial, the board will notify the public and make the proposed changes and the information submitted by the CAFO owner or operator available for public review and comment. The process for public comments, public hearing requests, and the public hearing process if a public hearing is held shall follow the procedures applicable to draft permits set forth in 9VAC25-31-300, 9VAC25-31-310 and 40 CFR 124.13
(2009). The board may establish, either by regulation or in the CAFO's permit, an appropriate period of time for the public to comment and request a public hearing on the proposed changes that differs from the time period specified in 9VAC25-31-290. The board will respond to all significant comments received during the comment period as provided in 9VAC25-31-320, and require the CAFO owner or operator to further revise the nutrient management plan if necessary, in order to approve the revision to the terms of the nutrient management plan incorporated into the CAFO's permit. Once the board incorporates the revised terms of the nutrient management plan into the permit, the board will notify the owner or operator and inform the public of the final decision concerning revisions to the terms and conditions of the permit.c. Substantial changes to the terms of a nutrient management plan incorporated as terms and conditions of a permit include, but are not limited to:
(1) Addition of new land application areas not previously included in the CAFO's nutrient management plan. Except that if the land application area that is being added to the nutrient management plan is covered by terms of a nutrient management plan incorporated into an existing VPDES permit in accordance with the requirements of subdivision E 5 of 9VAC25-31-200, and the CAFO owner or operator applies manure, litter, or process wastewater on the newly added land application area in accordance with the existing field-specific permit terms applicable to the newly added land application area, such addition of new land would be a change to the new CAFO owner or operator's nutrient management plan but not a substantial change for purposes of this section;
(2) Any changes to the field-specific maximum annual rates for land application, as set forth in subdivision E 5 a of 9VAC25-31-200, and to the maximum amounts of nitrogen and phosphorus derived from all sources for each crop, as set forth in subdivision E 5 b of 9VAC25-31-200;
(3) Addition of any crop or other uses not included in the terms of the CAFO's nutrient management plan and corresponding field-specific rates of application expressed in accordance with subdivision E 5 of 9VAC25-31-200; and
(4) Changes to site-specific components of the CAFO's nutrient management plan, where such changes are likely to increase the risk of nitrogen and phosphorus transport to state waters.
10. Causes for modification of nutrient management plans. The incorporation of the terms of a CAFO's nutrient management plan into the terms and conditions of a general permit when a CAFO obtains coverage under a general permit in accordance with subdivision C 8 of 9VAC25-31-130 and 9VAC25-31-170 is not a cause for modification pursuant to the requirements of 9VAC25-31-370.
9VAC25-31-150. Aquaculture projects.
Discharges into aquaculture projects, as defined in this chapter, are subject to the VPDES permit program. Permits for aquaculture projects shall be issued according to the criteria of 40 CFR Part 125, Subpart B
(2000).Part III
Permit Conditions9VAC25-31-190. Conditions applicable to all permits.
The following conditions apply to all VPDES permits. Additional conditions applicable to VPDES permits are in 9VAC25-31-200. All conditions applicable to VPDES permits shall be incorporated into the permits either expressly or by reference. If incorporated by reference, a specific citation to this regulation must be given in the permit.
A. The permittee must comply with all conditions of the permit. Any permit noncompliance constitutes a violation of the law and the CWA, except that noncompliance with certain provisions of the permit may constitute a violation of the law but not the CWA. Permit noncompliance is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or denial of a permit renewal application.
The permittee shall comply with effluent standards or prohibitions established under § 307(a) of the CWA for toxic pollutants and with standards for sewage sludge use or disposal established under § 405(d) of the CWA within the time provided in the chapters that establish these standards or prohibitions or standards for sewage sludge use or disposal, even if the permit has not yet been modified to incorporate the requirement.
B. If the permittee wishes to continue an activity regulated by the permit after the expiration date of the permit, the permittee must apply for and obtain a new permit.
C. It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of the permit.
D. The permittee shall take all reasonable steps to minimize or prevent any discharge or sludge use or disposal in violation of the permit which has a reasonable likelihood of adversely affecting human health or the environment.
E. The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of the permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of the permit.
F. Permits may be modified, revoked and reissued, or terminated for cause. The filing of a request by the permittee for a permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any permit condition.
G. Permits do not convey any property rights of any sort, or any exclusive privilege.
H. The permittee shall furnish to the department, within a reasonable time, any information which the board may request to determine whether cause exists for modifying, revoking and reissuing, or terminating the permit or to determine compliance with the permit. The board may require the permittee to furnish, upon request, such plans, specifications, and other pertinent information as may be necessary to determine the effect of the wastes from his discharge on the quality of state waters, or such other information as may be necessary to accomplish the purposes of the law. The permittee shall also furnish to the department upon request, copies of records required to be kept by the permit.
I. The permittee shall allow the director, or an authorized representative (including an authorized contractor acting as a representative of the administrator), upon presentation of credentials and other documents as may be required by law, to:
1. Enter upon the permittee's premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of the permit;
2. Have access to and copy, at reasonable times, any records that must be kept under the conditions of the permit;
3. Inspect at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under the permit; and
4. Sample or monitor at reasonable times, for the purposes of assuring permit compliance or as otherwise authorized by the CWA and the law, any substances or parameters at any location.
J. Monitoring and records.
1. Samples and measurements taken for the purpose of monitoring shall be representative of the monitored activity.
2. Except for records of monitoring information required by the permit related to the permittee's sewage sludge use and disposal activities, which shall be retained for a period of at least five years (or longer as required by Part VI (9VAC25-31-420 et seq.) of this chapter), the permittee shall retain records of all monitoring information, including all calibration and maintenance records and all original strip chart recordings for continuous monitoring instrumentation, copies of all reports required by the permit, and records of all data used to complete the application for the permit, for a period of at least three years from the date of the sample, measurement, report or application. This period of retention shall be extended automatically during the course of any unresolved litigation regarding the regulated activity or regarding control standards applicable to the permittee, or as requested by the board.
3. Records of monitoring information shall include:
a. The date, exact place, and time of sampling or measurements;
b. The individual or individuals who performed the sampling or measurements;
c. The date or dates analyses were performed;
d. The individual or individuals who performed the analyses;
e. The analytical techniques or methods used; and
f. The results of such analyses.
4. Monitoring results must be conducted according to test procedures approved under 40 CFR Part 136
(2000)or alternative EPA approved methods; or, in the case of sludge use or disposal, approved under 40 CFR Part 136(2000)unless otherwise specified in Part VI of this chapter, unless other test procedures have been specified in the permit.K. All applications, reports, or information submitted to the department shall be signed and certified as required by 9VAC25-31-110.
L. Reporting requirements.
1. The permittee shall give notice to the department as soon as possible of any planned physical alterations or additions to the permitted facility. Notice is required only when:
a. The alteration or addition to a permitted facility may meet one of the criteria for determining whether a facility is a new source in 9VAC25-31-180 A; or
b. The alteration or addition could significantly change the nature or increase the quantity of pollutants discharged. This notification applies to pollutants which are subject neither to effluent limitations in the permit, nor to notification requirements under 9VAC25-31-200 A 1.
c. The alteration or addition results in a significant change in the permittee's sludge use or disposal practices, and such alteration, addition, or change may justify the application of permit conditions that are different from or absent in the existing permit, including notification of additional use or disposal sites not reported during the permit application process or not reported pursuant to an approved land application plan;
2. The permittee shall give advance notice to the department of any planned changes in the permitted facility or activity which may result in noncompliance with permit requirements.
3. Permits are not transferable to any person except after notice to the department. The board may require modification or revocation and reissuance of permits to change the name of the permittee and incorporate such other requirements as may be necessary under the law or the CWA.
4. Monitoring results shall be reported at the intervals specified in the permit.
a. Monitoring results must be reported on a Discharge Monitoring Report (DMR) or forms provided or specified by the department for reporting results of monitoring of sludge use or disposal practices.
b. If the permittee monitors any pollutant specifically addressed by the permit more frequently than required by the permit using test procedures approved under 40 CFR Part 136
(2000)or, in the case of sludge use or disposal, approved under 40 CFR Part 136(2000)unless otherwise specified in Part VI of this chapter, or as specified in the permit, the results of this monitoring shall be included in the calculation and reporting of the data submitted in the DMR or sludge reporting form specified by the department.c. Calculations for all limitations which require averaging of measurements shall utilize an arithmetic mean unless otherwise specified in the permit.
5. Reports of compliance or noncompliance with, or any progress reports on, interim and final requirements contained in any compliance schedule of the permit shall be submitted no later than 14 days following each schedule date.
6. If any unusual or extraordinary discharge including a bypass or upset should occur from a facility and such discharge enters or could be expected to enter state waters, the owner shall promptly notify, in no case later than 24 hours, the department by telephone after the discovery of such discharge. This notification shall provide all available details of the incident, including any adverse affects on aquatic life and the known number of fish killed. The permittee shall reduce the report to writing and shall submit it to the department within five days of discovery of the discharge in accordance with subdivision 7 a of this subsection. Unusual and extraordinary discharges include but are not limited to any discharge resulting from:
a. Unusual spillage of materials resulting directly or indirectly from processing operations;
b. Breakdown of processing or accessory equipment;
c. Failure or taking out of service of the treatment plant or auxiliary facilities (such as sewer lines or wastewater pump stations); and
d. Flooding or other acts of nature.
7. Twenty-four hour reporting.
a. The permittee shall report any noncompliance which may endanger health or the environment. Any information shall be provided orally within 24 hours from the time the permittee becomes aware of the circumstances. A written submission shall also be provided within five days of the time the permittee becomes aware of the circumstances. The written submission shall contain a description of the noncompliance and its cause; the period of noncompliance, including exact dates and times, and if the noncompliance has not been corrected, the anticipated time it is expected to continue; and steps taken or planned to reduce, eliminate, and prevent reoccurrence of the noncompliance.
b. The following shall be included as information which must be reported within 24 hours under this subdivision:
(1) Any unanticipated bypass which exceeds any effluent limitation in the permit.
(2) Any upset which exceeds any effluent limitation in the permit.
(3) Violation of a maximum daily discharge limitation for any of the pollutants listed in the permit to be reported within 24 hours.
c. The board may waive the written report on a case-by-case basis for reports under this subdivision if the oral report has been received within 24 hours.
8. The permittee shall report all instances of noncompliance not reported under subdivisions 4, 5, 6, and 7 of this subsection, in writing at the time the next monitoring reports are submitted. The reports shall contain the information listed in subdivision 7 of this subsection.
9. Where the permittee becomes aware that it failed to submit any relevant facts in a permit application, or submitted incorrect information in a permit application or in any report to the department, it shall promptly submit such facts or information.
M. Bypass.
1. The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of subdivisions 2 and 3 of this subsection.
2. Notice.
a. Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least 10 days before the date of the bypass.
b. Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in subdivision L 7 of this section (24-hour notice).
3. Prohibition of bypass.
a. Bypass is prohibited, and the board may take enforcement action against a permittee for bypass, unless:
(1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;
(2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and
(3) The permittee submitted notices as required under subdivision 2 of this subsection.
b. The board may approve an anticipated bypass, after considering its adverse effects, if the board determines that it will meet the three conditions listed above in subdivision 3 a of this subsection.
N. Upset.
1. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of subdivision 2 of this subsection are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review.
2. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:
a. An upset occurred and that the permittee can identify the cause or causes of the upset;
b. The permitted facility was at the time being properly operated;
c. The permittee submitted notice of the upset as required in subdivision L 7 b (2) of this section (24-hour notice); and
d. The permittee complied with any remedial measures required under subsection D of this section.
3. In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has the burden of proof.
9VAC25-31-200. Additional conditions applicable to specified categories of VPDES permits.
The following conditions, in addition to those set forth in 9VAC25-31-190, apply to all VPDES permits within the categories specified below:
A. Existing manufacturing, commercial, mining, and silvicultural dischargers. All existing manufacturing, commercial, mining, and silvicultural dischargers must notify the department as soon as they know or have reason to believe:
1. That any activity has occurred or will occur which would result in the discharge, on a routine or frequent basis, of any toxic pollutant which is not limited in the permit, if that discharge will exceed the highest of the following notification levels:
a. One hundred micrograms per liter (100 μg/l);
b. Two hundred micrograms per liter (200 μg/l) for acrolein and acrylonitrile; five hundred micrograms per liter (500 μg/l) for 2,4-dinitrophenol and for 2-methyl-4,6-dinitrophenol; and one milligram per liter (1 mg/l) for antimony;
c. Five times the maximum concentration value reported for that pollutant in the permit application; or
d. The level established by the board in accordance with 9VAC25-31-220 F.
2. That any activity has occurred or will occur which would result in any discharge, on a nonroutine or infrequent basis, of a toxic pollutant which is not limited in the permit, if that discharge will exceed the highest of the following notification levels:

b. One milligram per liter (1 mg/l) for antimony;
c. Ten times the maximum concentration value reported for that pollutant in the permit application; or
d. The level established by the board in accordance with 9VAC25-31-220 F.
B. Publicly and privately owned treatment works. All POTWs and PVOTWs must provide adequate notice to the department of the following:
1. Any new introduction of pollutants into the POTW or PVOTW from an indirect discharger which would be subject to § 301 or § 306 of the CWA and the law if it were directly discharging those pollutants; and
2. Any substantial change in the volume or character of pollutants being introduced into that POTW or PVOTW by a source introducing pollutants into the POTW or PVOTW at the time of issuance of the permit.
3. For purposes of this subsection, adequate notice shall include information on (i) the quality and quantity of effluent introduced into the POTW or PVOTW, and (ii) any anticipated impact of the change on the quantity or quality of effluent to be discharged from the POTW or PVOTW.
4. When the monthly average flow influent to a POTW or PVOTW reaches 95% of the design capacity authorized by the VPDES permit for each month of any three-month period, the owner shall within 30 days notify the department in writing and within 90 days submit a plan of action for ensuring continued compliance with the terms of the permit.
a. The plan shall include the necessary steps and a prompt schedule of implementation for controlling any current problem, or any problem which could be reasonably anticipated, resulting from high influent flows.
b. Upon receipt of the owner's plan of action, the board shall notify the owner whether the plan is approved or disapproved. If the plan is disapproved, such notification shall state the reasons and specify the actions necessary to obtain approval of the plan.
c. Failure to timely submit an adequate plan shall be deemed a violation of the permit.
d. Nothing herein shall in any way impair the authority of the board to take enforcement action under §§ 62.1-44.15, 62.1-44.23, or 62.1-44.32 of the Code of Virginia.
C. Wastewater works operator requirements.
1. The permittee shall employ or contract at least one wastewater works operator who holds a current wastewater license appropriate for the permitted facility. The license shall be issued in accordance with Title 54.1 of the Code of Virginia and the regulations of the Board for Waterworks and Wastewater Works Operators (18VAC160-20). Not withstanding the foregoing requirement, unless the discharge is determined by the board on a case-by-case basis to be a potential contributor of pollution, no licensed operator is required for wastewater treatment works:
a. That have a design hydraulic capacity equal to or less than 0.04 mgd;
b. That discharge industrial waste or other waste from coal mining operations; or
c. That do not utilize biological or physical/chemical treatment.
2. In making this case-by-case determination, the board shall consider the location of the discharge with respect to state waters, the size of the discharge, the quantity and nature of pollutants reaching state waters and the treatment methods used at the wastewater works.
3. The permittee shall notify the department in writing whenever he is not complying, or has grounds for anticipating he will not comply with the requirements of subdivision 1 of this subsection. The notification shall include a statement of reasons and a prompt schedule for achieving compliance.
D. Lake level contingency plans. Any VPDES permit issued for a surface water impoundment whose primary purpose is to provide cooling water to power generators shall include a lake level contingency plan to allow specific reductions in the flow required to be released when the water level above the dam drops below designated levels due to drought conditions, and such plan shall take into account and minimize any adverse effects of any release reduction requirements on downstream users. This subsection shall not apply to any such facility that addresses releases and flow requirements during drought conditions in a Virginia Water Protection Permit.
E. Concentrated Animal Feeding Operations (CAFOs). The activities of the CAFO shall not contravene the Water Quality Standards, as amended and adopted by the board, or any provision of the State Water Control Law. There shall be no point source discharge of manure, litter or process wastewater to surface waters of the state except in the case of an overflow caused by a storm event greater than the 25-year, 24-hour storm. Agricultural storm water discharges as defined in subdivision C 4 of 9VAC25-31-130 are permitted. Domestic sewage or industrial waste shall not be managed under the Virginia Pollutant Discharge Elimination System General Permit for CAFOs (9VAC25-191). Any permit issued to a CAFO shall include:
1. Requirements to develop, implement and comply with a nutrient management plan. At a minimum, a nutrient management plan shall include best management practices and procedures necessary to implement applicable effluent limitations and standards. Permitted CAFOs must have their nutrient management plans developed and implemented and be in compliance with the nutrient management plan as a requirement of the permit. The nutrient management plan must, to the extent applicable:
a. Ensure adequate storage of manure, litter, and process wastewater, including procedures to ensure proper operation and maintenance of the storage facilities;
b. Ensure proper management of mortalities (i.e., dead animals) to ensure that they are not disposed of in a liquid manure, storm water, or process wastewater storage or treatment system that is not specifically designed to treat animal mortalities;
c. Ensure that clean water is diverted, as appropriate, from the production area;
d. Prevent direct contact of confined animals with surface waters of the state;
e. Ensure that chemicals and other contaminants handled onsite are not disposed of in any manure, litter, process wastewater, or stormwater storage or treatment system unless specifically designed to treat such chemicals and other contaminants;
f. Identify appropriate site specific conservation practices to be implemented, including as appropriate buffers or equivalent practices, to control runoff of pollutants to surface waters of the state;
g. Identify protocols for appropriate testing of manure, litter, process wastewater and soil;
h. Establish protocols to land apply manure, litter or process wastewater in accordance with site specific nutrient management practices that ensure appropriate agricultural utilization of the nutrients in the manure, litter or process wastewater; and
i. Identify specific records that will be maintained to document the implementation and management of the minimum elements described above.
2. Recordkeeping requirements. The permittee must create, maintain for five years, and make available to the director upon request the following records:
a. All applicable records identified pursuant to subdivision 1 i of this subsection;
b. In addition, all CAFOs subject to EPA Effluent Guidelines for Feedlots (40 CFR Part 412) must comply with recordkeeping requirements as specified in 40 CFR 412.37(b) and (c) and 40 CFR 412.47(b) and (c);
A copy of the CAFO's site-specific nutrient management plan must be maintained on site and made available to the director upon request.
3. Requirements relating to transfer of manure or process wastewater to other persons. Prior to transferring manure, litter or process wastewater to other persons, large CAFOs must provide the recipient of the manure, litter or process wastewater with the most current nutrient analysis. The analysis provided must be consistent with the requirements of EPA Effluent Guidelines for Feedlots (40 CFR Part 412). Large CAFOs must retain for five years records of the date, recipient name and address and approximate amount of manure, litter or process wastewater transferred to another person.
4. Annual reporting requirements for CAFOs. The permittee must submit an annual report to the director. The annual report must include:
a. The number and type of animals, whether in open confinement or housed under roof (beef cattle, broilers, layers, swine weighing 55 pounds or more, swine weighing less than 55 pounds, mature dairy cows, dairy heifers, veal calves, sheep and lambs, horses, ducks, turkeys, other);
b. Estimated amount of total manure, litter and process wastewater generated by the CAFO in the previous 12 months (tons/gallons);
c. Estimated amount of total manure, litter and process wastewater transferred to other persons by the CAFO in the previous 12 months (tons/gallons);
d. Total number of acres for land application covered by the nutrient management plan developed in accordance with subdivision 1 of this subsection;
e. Total number of acres under control of the CAFO that were used for land application of manure, litter and process wastewater in the previous 12 months;
f. Summary of all manure, litter and process wastewater discharges from the production area that occurred in the previous 12 months including date, time and approximate volume;
g. A statement indicating whether the current version of the CAFO's nutrient management plan was developed or approved by a certified nutrient management planner; and
h. The actual crop(s) planted and actual yield(s) for each field, the actual nitrogen and phosphorus content of the manure, litter, and process wastewater, the results of calculations conducted in accordance with subdivisions 5 a (2) and 5 b (4) of this subsection, and the amount of manure, litter, and process wastewater applied to each field during the previous 12 months; and, for any CAFO that implements a nutrient management plan that addresses rates of application in accordance with subdivision 5 b of this subsection, the results of any soil testing for nitrogen and phosphorus taken during the preceding 12 months, the data used in calculations conducted in accordance with subdivision 5 b (4) of this subsection, and the amount of any supplemental fertilizer applied during the previous 12 months.
5. Terms of the nutrient management plan. Any permit issued to a CAFO shall require compliance with the terms of the CAFO's site-specific nutrient management plan. The terms of the nutrient management plan are the information, protocols, best management practices, and other conditions in the nutrient management plan determined by the board to be necessary to meet the requirements of subdivision 1 of this subsection. The terms of the nutrient management plan, with respect to protocols for land application of manure, litter, or process wastewater required by subdivision 4 h of this subsection and, as applicable, 40 CFR 412.4(c)
(2009), shall include the fields available for land application; field-specific rates of application properly developed, as specified in subdivisions 5 a and b of this subsection, to ensure appropriate agricultural utilization of the nutrients in the manure, litter, or process wastewater; and any timing limitations identified in the nutrient management plan concerning land application on the fields available for land application. The terms shall address rates of application using one of the following two approaches, unless the board specifies that only one of these approaches may be used:a. Linear approach. An approach that expresses rates of application as pounds of nitrogen and phosphorus, according to the following specifications:
(1) The terms include maximum application rates from manure, litter, and process wastewater for each year of permit coverage, for each crop identified in the nutrient management plan, in chemical forms determined to be acceptable to the board, in pounds per acre, per year, for each field to be used for land application, and certain factors necessary to determine such rates. At a minimum, the factors that are terms shall include: the outcome of the field-specific assessment of the potential for nitrogen and phosphorus transport from each field; the crops to be planted in each field or any other uses of a field such as pasture or fallow fields; the realistic yield goal for each crop or use identified for each field; the nitrogen and phosphorus recommendations from sources specified by the board for each crop or use identified for each field; credits for all nitrogen in the field that will be plant available; consideration of multi-year phosphorus application; and accounting for all other additions of plant available nitrogen and phosphorus to the field. In addition, the terms include the form and source of manure, litter, and process wastewater to be land-applied; the timing and method of land application; and the methodology by which the nutrient management plan accounts for the amount of nitrogen and phosphorus in the manure, litter, and process wastewater to be applied.
(2) Large CAFOs that use this approach shall calculate the maximum amount of manure, litter, and process wastewater to be land applied at least once each year using the results of the most recent representative manure, litter, and process wastewater tests for nitrogen and phosphorus taken within 12 months of the date of land application; or
b. Narrative rate approach. An approach that expresses rates of application as a narrative rate of application that results in the amount, in tons or gallons, of manure, litter, and process wastewater to be land applied, according to the following specifications:
(1) The terms include maximum amounts of nitrogen and phosphorus derived from all sources of nutrients, for each crop identified in the nutrient management plan, in chemical forms determined to be acceptable to the board, in pounds per acre, for each field, and certain factors necessary to determine such amounts. At a minimum, the factors that are terms shall include: the outcome of the field-specific assessment of the potential for nitrogen and phosphorus transport from each field; the crops to be planted in each field or any other uses such as pasture or fallow fields (including alternative crops identified in accordance with subdivision 5 b (2) of this subsection); the realistic yield goal for each crop or use identified for each field; and the nitrogen and phosphorus recommendations from sources specified by the board for each crop or use identified for each field. In addition, the terms include the methodology by which the nutrient management plan accounts for the following factors when calculating the amounts of manure, litter, and process wastewater to be land applied: results of soil tests conducted in accordance with protocols identified in the nutrient management plan, as required by subdivision 1 g of this subsection; credits for all nitrogen in the field that will be plant available; the amount of nitrogen and phosphorus in the manure, litter, and process wastewater to be applied; consideration of multi-year phosphorus application; accounting for all other additions of plant available nitrogen and phosphorus to the field; the form and source of manure, litter, and process wastewater; the timing and method of land application; and volatilization of nitrogen and mineralization of organic nitrogen.
(2) The terms of the nutrient management plan include alternative crops identified in the CAFO's nutrient management plan that are not in the planned crop rotation. Where a CAFO includes alternative crops in its nutrient management plan, the crops shall be listed by field, in addition to the crops identified in the planned crop rotation for that field, and the nutrient management plan shall include realistic crop yield goals and the nitrogen and phosphorus recommendations from sources specified by the board for each crop. Maximum amounts of nitrogen and phosphorus from all sources of nutrients and the amounts of manure, litter, and process wastewater to be applied shall be determined in accordance with the methodology described in subdivision 5 b (1) of this subsection.
(3) For CAFOs using this approach, the following projections shall be included in the nutrient management plan submitted to the board, but are not terms of the nutrient management plan: the CAFO's planned crop rotations for each field for the period of permit coverage; the projected amount of manure, litter, or process wastewater to be applied; projected credits for all nitrogen in the field that will be plant available; consideration of multi-year phosphorus application; accounting for all other additions of plant available nitrogen and phosphorus to the field; and the predicted form, source, and method of application of manure, litter, and process wastewater for each crop. Timing of application for each field, insofar as it concerns the calculation of rates of application, is not a term of the nutrient management plan.
(4) CAFOs that use this approach shall calculate maximum amounts of manure, litter, and process wastewater to be land applied at least once each year using the methodology required in subdivision 5 b (1) of this subsection before land applying manure, litter, and process wastewater and shall rely on the following data:
(a) A field-specific determination of soil levels of nitrogen and phosphorus, including, for nitrogen, a concurrent determination of nitrogen that will be plant available consistent with the methodology required by subdivision 5 b (1) of this subsection, and for phosphorus, the results of the most recent soil test conducted in accordance with soil testing requirements approved by the board; and
(b) The results of most recent representative manure, litter, and process wastewater tests for nitrogen and phosphorus taken within 12 months of the date of land application, in order to determine the amount of nitrogen and phosphorus in the manure, litter, and process wastewater to be applied.
9VAC25-31-220. Establishing limitations, standards, and other permit conditions.
In addition to the conditions established under 9VAC25-31-210 A, each VPDES permit shall include conditions meeting the following requirements when applicable.
A. 1. Technology-based effluent limitations and standards based on effluent limitations and standards promulgated under § 301 of the CWA, on new source performance standards promulgated under § 306 of CWA, on case-by-case effluent limitations determined under § 402(a)(1) of CWA, or a combination of the three. For new sources or new dischargers, these technology-based limitations and standards are subject to the provisions of 9VAC25-31-180 B (protection period).
2. The board may authorize a discharger subject to technology-based effluent limitations guidelines and standards in a VPDES permit to forego sampling of a pollutant found at 40 CFR Subchapter N
(2005)if the discharger has demonstrated through sampling and other technical factors that the pollutant is not present in the discharge or is present only at background levels from intake water and without any increase in the pollutant due to activities of the discharger. This waiver is good only for the term of the permit and is not available during the term of the first permit issued to a discharger. Any request for this waiver must be submitted when applying for a reissued permit or modification of a reissued permit. The request must demonstrate through sampling or other technical information, including information generated during an earlier permit term, that the pollutant is not present in the discharge or is present only at background levels from intake water and without any increase in the pollutant due to activities of the discharger. Any grant of the monitoring waiver must be included in the permit as an express permit condition and the reasons supporting the grant must be documented in the permit's fact sheet or statement of basis. This provision does not supersede certification processes and requirements already established in existing effluent limitations guidelines and standards.B. Other effluent limitations and standards.
1. Other effluent limitations and standards under §§ 301, 302, 303, 307, 318 and 405 of the CWA. If any applicable toxic effluent standard or prohibition (including any schedule of compliance specified in such effluent standard or prohibition) is promulgated under § 307(a) of the CWA for a toxic pollutant and that standard or prohibition is more stringent than any limitation on the pollutant in the permit, the board shall institute proceedings under this chapter to modify or revoke and reissue the permit to conform to the toxic effluent standard or prohibition.
2. Standards for sewage sludge use or disposal under § 405(d) of the CWA and Part VI (9VAC25-31-420 et seq.) of this chapter unless those standards have been included in a permit issued under the appropriate provisions of Subtitle C of the Solid Waste Disposal Act (42 USC § 6901 et seq.), Part C of Safe Drinking Water Act (42 USC § 300f et seq.), the Marine Protection, Research, and Sanctuaries Act of 1972 (33 USC § 1401 et seq.), or the Clean Air Act (42 USC § 4701 et seq.), or in another permit issued by the Department of Environmental Quality or any other appropriate state agency under another permit program approved by the administrator. When there are no applicable standards for sewage sludge use or disposal, the permit may include requirements developed on a case-by-case basis to protect public health and the environment from any adverse effects which may occur from toxic pollutants in sewage sludge. If any applicable standard for sewage sludge use or disposal is promulgated under § 405(d) of the CWA and that standard is more stringent than any limitation on the pollutant or practice in the permit, the board may initiate proceedings under this chapter to modify or revoke and reissue the permit to conform to the standard for sewage sludge use or disposal.
3. Requirements applicable to cooling water intake structures at new facilities under § 316 (b) of the CWA, in accordance with 9VAC25-31-165.
C. Reopener clause. For any permit issued to a treatment works treating domestic sewage (including sludge-only facilities), the board shall include a reopener clause to incorporate any applicable standard for sewage sludge use or disposal promulgated under § 405(d) of the CWA. The board may promptly modify or revoke and reissue any permit containing the reopener clause required by this subdivision if the standard for sewage sludge use or disposal is more stringent than any requirements for sludge use or disposal in the permit, or controls a pollutant or practice not limited in the permit.
D. Water quality standards and state requirements. Any requirements in addition to or more stringent than promulgated effluent limitations guidelines or standards under §§ 301, 304, 306, 307, 318 and 405 of the CWA necessary to:
1. Achieve water quality standards established under the law and § 303 of the CWA, including state narrative criteria for water quality.
a. Limitations must control all pollutants or pollutant parameters (either conventional, nonconventional, or toxic pollutants) which the board determines are or may be discharged at a level which will cause, have the reasonable potential to cause, or contribute to an excursion above any Virginia water quality standard, including Virginia narrative criteria for water quality.
b. When determining whether a discharge causes, has the reasonable potential to cause, or contributes to an in-stream excursion above a narrative or numeric criteria within a Virginia water quality standard, the board shall use procedures which account for existing controls on point and nonpoint sources of pollution, the variability of the pollutant or pollutant parameter in the effluent, the sensitivity of the species to toxicity testing (when evaluating whole effluent toxicity), and where appropriate, the dilution of the effluent in the receiving water.
c. When the board determines, using the procedures in subdivision 1 b of this subsection, that a discharge causes, has the reasonable potential to cause, or contributes to an in-stream excursion above the allowable ambient concentration of a Virginia numeric criteria within a Virginia water quality standard for an individual pollutant, the permit must contain effluent limits for that pollutant.
d. Except as provided in this subdivision, when the board determines, using the procedures in subdivision 1 b of this subsection, toxicity testing data, or other information, that a discharge causes, has the reasonable potential to cause, or contributes to an in-stream excursion above a narrative criterion within an applicable Virginia water quality standard, the permit must contain effluent limits for whole effluent toxicity. Limits on whole effluent toxicity are not necessary where the board demonstrates in the fact sheet or statement of basis of the VPDES permit, using the procedures in subdivision 1 b of this subsection, that chemical-specific limits for the effluent are sufficient to attain and maintain applicable numeric and narrative Virginia water quality standards.
e. Where Virginia has not established a water quality criterion for a specific chemical pollutant that is present in an effluent at a concentration that causes, has the reasonable potential to cause, or contributes to an excursion above a narrative criterion within an applicable Virginia water quality standard, the board must establish effluent limits using one or more of the following options:
(1) Establish effluent limits using a calculated numeric water quality criterion for the pollutant which the board demonstrates will attain and maintain applicable narrative water quality criteria and will fully protect the designated use. Such a criterion may be derived using a proposed Virginia criterion, or an explicit policy or regulation interpreting Virginia's narrative water quality criterion, supplemented with other relevant information which may include: EPA's Water Quality Standards Handbook, August 1994, risk assessment data, exposure data, information about the pollutant from the Food and Drug Administration, and current EPA criteria documents;
(2) Establish effluent limits on a case-by-case basis, using EPA's water quality criteria, published under § 307(a) of the CWA, supplemented where necessary by other relevant information; or
(3) Establish effluent limitations on an indicator parameter for the pollutant of concern, provided:
(a) The permit identifies which pollutants are intended to be controlled by the use of the effluent limitation;
(b) The fact sheet required by 9VAC25-31-280 sets forth the basis for the limit, including a finding that compliance with the effluent limit on the indicator parameter will result in controls on the pollutant of concern which are sufficient to attain and maintain applicable water quality standards;
(c) The permit requires all effluent and ambient monitoring necessary to show that during the term of the permit the limit on the indicator parameter continues to attain and maintain applicable water quality standards; and
(d) The permit contains a reopener clause allowing the board to modify or revoke and reissue the permit if the limits on the indicator parameter no longer attain and maintain applicable water quality standards.
f. When developing water quality-based effluent limits under this subdivision the board shall ensure that:
(1) The level of water quality to be achieved by limits on point sources established under this subsection is derived from, and complies with all applicable water quality standards; and
(2) Effluent limits developed to protect a narrative water quality criterion, a numeric water quality criterion, or both, are consistent with the assumptions and requirements of any available wasteload allocation for the discharge prepared by Virginia and approved by EPA pursuant to 40 CFR 130.7
(2005);2. Attain or maintain a specified water quality through water quality related effluent limits established under the law and § 302 of the CWA;
3. Conform to the conditions of a Virginia Water Protection Permit (VWPP) issued under the law and § 401 of the CWA;
4. Conform to applicable water quality requirements under § 401(a)(2) of the CWA when the discharge affects a state other than Virginia;
5. Incorporate any more stringent limitations, treatment standards, or schedule of compliance requirements established under the law or regulations in accordance with § 301(b)(1)(C) of the CWA;
6. Ensure consistency with the requirements of a Water Quality Management plan approved by EPA under § 208(b) of the CWA;
7. Incorporate § 403(c) criteria under 40 CFR Part 125, Subpart M
(2005), for ocean discharges; or8. Incorporate alternative effluent limitations or standards where warranted by fundamentally different factors, under 40 the CFR Part 125, Subpart D
(2005).E. Technology-based controls for toxic pollutants. Limitations established under subsections A, B, or D of this section, to control pollutants meeting the criteria listed in subdivision 1 of this subsection. Limitations will be established in accordance with subdivision 2 of this subsection. An explanation of the development of these limitations shall be included in the fact sheet.
1. Limitations must control all toxic pollutants which the board determines (based on information reported in a permit application or in a notification required by the permit or on other information) are or may be discharged at a level greater than the level which can be achieved by the technology-based treatment requirements appropriate to the permittee; or
2. The requirement that the limitations control the pollutants meeting the criteria of subdivision 1 of this subsection will be satisfied by:
a. Limitations on those pollutants; or
b. Limitations on other pollutants which, in the judgment of the board, will provide treatment of the pollutants under subdivision 1 of this subsection to the levels required by the law and 40 CFR Part 125, Subpart A
(2005).F. A notification level which exceeds the notification level of 9VAC25-31-200 A 1 a, b, or c, upon a petition from the permittee or on the board's initiative. This new notification level may not exceed the level which can be achieved by the technology-based treatment requirements appropriate to the permittee.
G. Twenty-four-hour reporting. Pollutants for which the permittee must report violations of maximum daily discharge limitations under 9VAC25-31-190 L 7 b (3) (24-hour reporting) shall be listed in the permit. This list shall include any toxic pollutant or hazardous substance, or any pollutant specifically identified as the method to control a toxic pollutant or hazardous substance.
H. Durations for permits, as set forth in 9VAC25-31-240.
I. Monitoring requirements. The following monitoring requirements:
1. Requirements concerning the proper use, maintenance, and installation, when appropriate, of monitoring equipment or methods (including biological monitoring methods when appropriate);
2. Required monitoring including type, intervals, and frequency sufficient to yield data which are representative of the monitored activity including, when appropriate, continuous monitoring;
3. Applicable reporting requirements based upon the impact of the regulated activity and as specified in 9VAC25-31-190 and in subdivisions 5 through 8 of this subsection. Reporting shall be no less frequent than specified in the above regulation;
4. To assure compliance with permit limitations, requirements to monitor:
a. The mass (or other measurement specified in the permit) for each pollutant limited in the permit;
b. The volume of effluent discharged from each outfall;
c. Other measurements as appropriate including pollutants in internal waste streams; pollutants in intake water for net limitations; frequency, rate of discharge, etc., for noncontinuous discharges; pollutants subject to notification requirements; and pollutants in sewage sludge or other monitoring as specified in Part VI (9VAC25-31-420 et seq.) of this chapter; or as determined to be necessary on a case-by-case basis pursuant to the law and § 405(d)(4) of the CWA; and
d. According to test procedures approved under 40 CFR Part 136
(2005)for the analyses of pollutants having approved methods under that part, or alternative EPA approved methods, and according to a test procedure specified in the permit for pollutants with no approved methods;5. Except as provided in subdivisions 7 and 8 of this subsection, requirements to report monitoring results shall be established on a case-by-case basis with a frequency dependent on the nature and effect of the discharge, but in no case less that once a year. For sewage sludge use or disposal practices, requirements to monitor and report results shall be established on a case-by-case basis with a frequency dependent on the nature and effect of the sewage sludge use or disposal practice; minimally this shall be as specified in Part VI (9VAC25-31-420 et seq.) of this chapter (where applicable), but in no case less than once a year;
6. Requirements to report monitoring results for storm water discharges associated with industrial activity which are subject to an effluent limitation guideline shall be established on a case-by-case basis with a frequency dependent on the nature and effect of the discharge, but in no case less than once a year;
7. Requirements to report monitoring results for storm water discharges associated with industrial activity (other than those addressed in subdivision 6 of this subsection) shall be established on a case-by-case basis with a frequency dependent on the nature and effect of the discharge. At a minimum, a permit for such a discharge must require:
a. The discharger to conduct an annual inspection of the facility site to identify areas contributing to a storm water discharge associated with industrial activity and evaluate whether measures to reduce pollutant loading identified in a storm water pollution prevention plan are adequate and properly implemented in accordance with the terms of the permit or whether additional control measures are needed;
b. The discharger to maintain for a period of three years a record summarizing the results of the inspection and a certification that the facility is in compliance with the plan and the permit, and identifying any incidents of noncompliance;
c. Such report and certification be signed in accordance with 9VAC25-31-110; and
d. Permits for storm water discharges associated with industrial activity from inactive mining operations may, where annual inspections are impracticable, require certification once every three years by a Registered Professional Engineer that the facility is in compliance with the permit, or alternative requirements; and
8. Permits which do not require the submittal of monitoring result reports at least annually shall require that the permittee report all instances of noncompliance not reported under 9VAC25-31-190 L 1, 4, 5, 6, and 7 at least annually.
J. Pretreatment program for POTWs. Requirements for POTWs to:
1. Identify, in terms of character and volume of pollutants, any significant indirect dischargers into the POTW subject to pretreatment standards under § 307(b) of the CWA and Part VII (9VAC25-31-730 et seq.) of this chapter;
2. Submit a local program when required by and in accordance with Part VII of this chapter to assure compliance with pretreatment standards to the extent applicable under § 307(b) of the CWA. The local program shall be incorporated into the permit as described in Part VII of this chapter. The program shall require all indirect dischargers to the POTW to comply with the reporting requirements of Part VII of this chapter;
3. Provide a written technical evaluation of the need to revise local limits under Part VII of this chapter following permit issuance or reissuance; and
4. For POTWs which are sludge-only facilities, a requirement to develop a pretreatment program under Part VII of this chapter when the board determines that a pretreatment program is necessary to assure compliance with Part VI of this chapter.
K. Best management practices to control or abate the discharge of pollutants when:
1. Authorized under § 304(e) of the CWA for the control of toxic pollutants and hazardous substances from ancillary industrial activities;
2. Authorized under § 402(p) of the CWA for the control of storm water discharges;
3. Numeric effluent limitations are infeasible; or
4. The practices are reasonably necessary to achieve effluent limitations and standards or to carry out the purposes and intent of the law and the CWA.
L. Reissued permits.
1. In the case of effluent limitations established on the basis of § 402(a)(1)(B) of the CWA, a permit may not be renewed, reissued, or modified on the basis of effluent guidelines promulgated under § 304(b) of the CWA subsequent to the original issuance of such permit, to contain effluent limitations which are less stringent than the comparable effluent limitations in the previous permit. In the case of effluent limitations established on the basis of §§ 301(b)(1)(C) or 303(d) or (e) of the CWA, a permit may not be renewed, reissued, or modified to contain effluent limitations which are less stringent than the comparable effluent limitations in the previous permit except in compliance with § 303(d)(4) of the CWA.
2. Exceptions. A permit with respect to which subdivision 1 of this subsection applies may be renewed, reissued, or modified to contain a less stringent effluent limitation applicable to a pollutant, if:
a. Material and substantial alterations or additions to the permitted facility occurred after permit issuance which justify the application of a less stringent effluent limitation;
b. (1) Information is available which was not available at the time of permit issuance (other than revised regulations, guidance, or test methods) and which would have justified the application of a less stringent effluent limitation at the time of permit issuance; or
(2) The board determines that technical mistakes or mistaken interpretations of law were made in issuing the permit under § 402(a)(1)(B) of the CWA;
c. A less stringent effluent limitation is necessary because of events over which the permittee has no control and for which there is no reasonably available remedy;
d. The permittee has received a permit modification under the law and §§ 301(c), 301(g), 301(h), 301(i), 301(k), 301(n), or 316(a) of the CWA; or
e. The permittee has installed the treatment facilities required to meet the effluent limitations in the previous permit and has properly operated and maintained the facilities but has nevertheless been unable to achieve the previous effluent limitations, in which case the limitations in the reviewed, reissued, or modified permit may reflect the level of pollutant control actually achieved (but shall not be less stringent than required by effluent guidelines in effect at the time of permit renewal, reissuance, or modification).
Subdivision 2 b of this subsection shall not apply to any revised waste load allocations or any alternative grounds for translating water quality standards into effluent limitations, except where the cumulative effect of such revised allocations results in a decrease in the amount of pollutants discharged into the concerned waters, and such revised allocations are not the result of a discharger eliminating or substantially reducing its discharge of pollutants due to complying with the requirements of the law or the CWA or for reasons otherwise unrelated to water quality.
3. In no event may a permit with respect to which subdivision 2 of this subsection applies be renewed, reissued, or modified to contain an effluent limitation which is less stringent than required by effluent guidelines in effect at the time the permit is renewed, reissued, or modified. In no event may such a permit to discharge into waters be renewed, issued, or modified to contain a less stringent effluent limitation if the implementation of such limitation would result in a violation of a Virginia water quality standard applicable to such waters.
M. For a privately owned treatment works, any conditions expressly applicable to any user, as a limited co-permittee, that may be necessary in the permit issued to the treatment works to ensure compliance with applicable requirements under this part. Alternatively, the board may issue separate permits to the treatment works and to its users, or may require a separate permit application from any user. The board's decision to issue a permit with no conditions applicable to any user, to impose conditions on one or more users, to issue separate permits, or to require separate applications, and the basis for that decision, shall be stated in the fact sheet for the draft permit for the treatment works.
N. Any conditions imposed in grants made by the board to POTWs under §§ 201 and 204 of the CWA which are reasonably necessary for the achievement of effluent limitations under § 301 of the CWA and the law.
O. Requirements governing the disposal of sewage sludge from publicly owned treatment works or any other treatment works treating domestic sewage for any use regulated by Part VI of this chapter.
P. When a permit is issued to a facility that may operate at certain times as a means of transportation over water, a condition that the discharge shall comply with any applicable regulations promulgated by the secretary of the department in which the Coast Guard is operating, that establish specifications for safe transportation, handling, carriage, and storage of pollutants.
Q. Navigation. Any conditions that the Secretary of the Army considers necessary to ensure that navigation and anchorage will not be substantially impaired in accordance with 9VAC25-31-330.
9VAC25-31-230. Calculating VPDES permit conditions.
A. Permit effluent limitations, monitoring requirements, standards and prohibitions shall be established for each outfall or discharge point of the permitted facility, except as otherwise provided under 9VAC25-31-220 and subsection H of this section (limitations on internal waste streams).
B. Production-based limitations.
1. In the case of POTWs, permit effluent limitations, standards, or prohibitions shall be calculated based on design flow.
2. a. Except in the case of POTWs or as provided in subdivision 2 b of this subsection, calculation of any permit limitations, standards, or prohibitions which are based on production (or other measure of operation) shall be based not upon the designed production capacity but rather upon a reasonable measure of actual production of the facility. For new sources or new dischargers, actual production shall be estimated using projected production. The time period of the measure of production shall correspond to the time period of the calculated permit limitations; for example, monthly production shall be used to calculate average monthly discharge limitations.
b. (1) (a) The board may include a condition establishing alternate permit limitations, standards, or prohibitions based upon anticipated increased (not to exceed maximum production capability) or decreased production levels.
(b) For the automotive manufacturing industry only, the board may establish a condition under subdivision 2 b (1) (a) of this subsection if the applicant satisfactorily demonstrates to the board at the time the application is submitted that its actual production, as indicated in subdivision 2 a of this subsection, is substantially below maximum production capability and that there is a reasonable potential for an increase above actual production during the duration of the permit.
(2) If the board establishes permit conditions under subdivision 2 b (1) of this subsection:
(a) The permit shall require the permittee to notify the department at least two business days prior to a month in which the permittee expects to operate at a level higher than the lowest production level identified in the permit. The notice shall specify the anticipated level and the period during which the permittee expects to operate at the alternate level. If the notice covers more than one month, the notice shall specify the reasons for the anticipated production level increase. New notice of discharge at alternate levels is required to cover a period or production level not covered by prior notice or, if during two consecutive months otherwise covered by a notice, the production level at the permitted facility does not in fact meet the higher level designated in the notice;
(b) The permittee shall comply with the limitations, standards, or prohibitions that correspond to the lowest level of production specified in the permit, unless the permittee has notified the department under subdivision 2 b (2) (a) of this subsection, in which case the permittee shall comply with the lower of the actual level of production during each month or the level specified in the notice; and
(c) The permittee shall submit with the DMR the level of production that actually occurred during each month and the limitations, standards, or prohibitions applicable to that level of production.
C. All permit effluent limitations, standards, or prohibitions for a metal shall be expressed in terms of total recoverable metal as defined in 40 CFR Part 136
(2000)unless:1. An applicable effluent standard or limitation has been promulgated under the CWA and specifies the limitation for the metal in the dissolved or valent or total form; or
2. In establishing permit limitations on a case-by-case basis under 40 CFR 125.3
(2000), it is necessary to express the limitation on the metal in the dissolved or valent or total form to carry out the provisions of the CWA and the law; or3. All approved analytical methods for the metal inherently measure only its dissolved form (e.g., hexavalent chromium).
D. For continuous discharges all permit effluent limitations, standards, and prohibitions, including those necessary to achieve water quality standards, shall unless impracticable be stated as:
1. Maximum daily and average monthly discharge limitations for all dischargers other than publicly owned treatment works; and
2. Average weekly and average monthly discharge limitations for POTWs.
E. Discharges which are not continuous, as defined in 9VAC25-31-10, shall be particularly described and limited, considering the following factors, as appropriate:
1. Frequency;
2. Total mass;
3. Maximum rate of discharge of pollutants during the discharge; and
4. Prohibition or limitation of specified pollutants by mass, concentration, or other appropriate measure.
F. Mass Limitations.
1. All pollutants limited in permits shall have limitations, standards or prohibitions expressed in terms of mass except:
a. For pH, temperature, radiation, or other pollutants which cannot appropriately be expressed by mass;
b. When applicable standards and limitations are expressed in terms of other units of measurement; or
c. If in establishing technology-based permit limitations on a case-by-case basis, limitations expressed in terms of mass are infeasible because the mass of the pollutant discharged cannot be related to a measure of operation (for example, discharges of TSS from certain mining operations), and permit conditions ensure that dilution will not be used as a substitute for treatment.
2. Pollutants limited in terms of mass additionally may be limited in terms of other units of measurement, and the permit shall require the permittee to comply with both limitations.
G. Pollutants in intake water.
1. Upon request of the discharger, technology-based effluent limitations or standards shall be adjusted to reflect credit for pollutants in the discharger's intake water to the extent necessary to meet the applicable technology-based limitation or standard, up to a maximum value equal to the influent value. Credit shall be granted only if:
a. The applicable effluent limitations and standards contained in the regulations incorporated by reference in 9VAC25-31-30 specifically provide that they shall be applied on a net basis; or
b. The discharger demonstrates that the control system it proposes or uses to meet applicable technology-based limitations and standards would, if properly installed and operated, meets the limitations and standards in the absence of pollutants in the intake waters.
2. Credit for generic pollutants such as biochemical oxygen demand (BOD) or total suspended solids (TSS) should not be granted unless the permittee demonstrates that the constituents of the generic measure in the effluent are substantially similar to the constituents of the generic measure in the intake water or unless appropriate additional limits are placed on process water pollutants either at the outfall or elsewhere.
3. Credit for the level of pollutants in the intake water may be considered in setting water quality-based effluent limitations according to 9VAC25-31-220 D. Where a total maximum daily load has been established for the receiving waterbody and it is applicable to the discharge, it shall be considered when such effluent limitations are developed. The board may consider the presence of intake pollutants when determining either that water quality-based effluent limitations are not necessary under 9VAC25-31-220 D or that any water quality-based effluent limitations justified by 9VAC25-31-220 D will be established in a manner that does not hold the permittee responsible for removing pollutants originating in its intake water.
4. Additional monitoring may be necessary to determine eligibility for any credits and compliance with permit limits.
5. Credits shall be granted only if the discharger demonstrates that the intake water is drawn from the same body of water into which the discharge is made. The board may waive this requirement for technology-based effluent limitations, standards, and prohibitions if he finds that no environmental degradation will result.
a. An intake pollutant is considered to be from the same body of water as the discharge if the board finds that the intake pollutant would have reached the vicinity of the outfall point in the receiving water within a reasonable period had it not been removed by the permittee. This finding may be deemed established if:
(1) The background concentration of the pollutant in the receiving water (excluding any amount of the pollutant in the facility's discharge) is similar to that in the intake water;
(2) There is direct hydrological connection between the intake and discharge points; and
(3) Water quality characteristics (e.g., temperature, pH, hardness) are similar in the intake and receiving waters.
Other site-specific factors relevant to the transport and fate of the pollutant may be considered in making this finding.
b. An intake pollutant from groundwater may be considered to be from the same body of water if the board determines that the pollutant would have reached the vicinity of the outfall point in the receiving water within a reasonable period had it not been removed by the permittee, except that such a pollutant is not from the same body of water if the groundwater contains the pollutant partially or entirely due to human activity, such as industrial, commercial, or municipal operations, disposal actions or treatment processes.
c. For pollutants in intake water provided by a water supply system, where the raw water supply is removed from the same body of water as the discharge, the concentration of the intake pollutant shall be determined at the point where the water enters the water supplier's distribution system.
d. Where a facility discharges intake pollutants that originate in part from the same body of water and in part from a different body of water, the effluent limitation may provide for intake credits for the portion of the pollutants derived from the same body of water, provided that adequate monitoring to determine compliance can be established and is included in the permit.
6. Credits shall not be granted if the discharger contributes to the level of the pollutant in the intake water prior to the intake.
7. Credits for intake pollutants do not apply to technology-based limitations on the discharge of raw water clarifier sludge generated from the treatment of intake water.
H. Internal waste streams.
1. When permit effluent limitations or standards imposed at the point of discharge are impractical or infeasible, effluent limitations or standards for discharges of pollutants may be imposed on internal waste streams before mixing with other waste streams or cooling water streams. In those instances, the monitoring required by 9VAC25-31-220 I shall also be applied to the internal waste streams.
2. Limits on internal waste streams will be imposed only when the fact sheet sets forth the exceptional circumstances which make such limitations necessary, such as when the final discharge point is inaccessible, the wastes at the point of discharge are so diluted as to make monitoring impracticable, or the interferences among pollutants at the point of discharge would make detection or analysis impracticable.
I. Disposal of pollutants into wells, POTWs or by land application.
1. When part of a discharger's process wastewater is not being discharged into surface waters or into the contiguous zone because it is disposed into a well, into a POTW, or by land application thereby reducing the flow or level of pollutants being discharged into surface waters, applicable effluent standards and limitations for the discharge in a VPDES permit shall be adjusted to reflect the reduced raw waste resulting from such disposal. Effluent limitations and standards in the permit shall be calculated by one of the following methods:
a. If none of the waste from a particular process is discharged into surface waters, and effluent limitations guidelines provide separate allocation for wastes from that process, all allocations for the process shall be eliminated from calculation of permit effluent limitations or standards.
b. In all cases other than those described in subdivision 1 a of this subsection, effluent limitations shall be adjusted by multiplying the effluent limitation derived by applying effluent limitation guidelines to the total waste stream by the amount of wastewater flow to be treated and discharged into surface waters, and dividing the result by the total wastewater flow. Effluent limitations and standards so calculated may be further adjusted to make them more or less stringent if discharges to wells, publicly owned treatment works, or by land application change the character or treatability of the pollutants being discharged to receiving waters. This method may be algebraically expressed as:
P =
E x N
T
where P is the permit effluent limitation, E is the limitation derived by applying effluent guidelines to the total wastestream, N is the wastewater flow to be treated and discharged to surface waters, and T is the total wastewater flow.
2. Subdivision 1 of this subsection does not apply to the extent that promulgated effluent limitations guidelines:
a. Control concentrations of pollutants discharged but not mass; or
b. Specify a different specific technique for adjusting effluent limitations to account for well injection, land application, or disposal into POTWs.
3. Subdivision 1 of this subsection does not alter a discharger's obligation to meet any more stringent requirements established in the permit.
9VAC25-31-340. Decision on variances.
A. The board may grant or deny requests for variances requested pursuant to 9VAC25-31-100 L 4, subject to EPA objection. Decisions on these variances shall be made according to the criteria of 40 CFR Part 125, Subpart H
(2000).B. The board may deny, or forward to the regional administrator with a written concurrence, or submit to EPA without recommendation a completed request for:
1. A variance based on the economic capability of the applicant submitted pursuant to 9VAC25-31-100 L 2; or
2. A variance based on water quality related effluent limitations submitted pursuant to 9VAC25-31-100 L 3 or 9VAC25-31-100 M 2.
C. If the EPA Office Director for Wastewater Management approves the variance, the board may prepare a draft permit incorporating the variance. Any public notice of a draft permit for which a variance or modification has been approved or denied shall identify the applicable procedures for appealing that decision.
D. The board may deny or forward to the administrator with a written concurrence a completed request for:
1. A variance based on the presence of fundamentally different factors from those on which an effluent limitations guideline was based, made according to the criteria and standards of 40 CFR Part 125, Subpart D
(2000); or2. A variance based upon certain water quality factors submitted pursuant to 9VAC25-31-100 L 2 or 9VAC25-31-100 M 1.
E. If the administrator approves the variance, the board may prepare a draft permit incorporating the variance. Any public notice of a draft permit for which a variance or modification has been approved or denied shall identify the applicable procedures for appealing that decision.

These general prohibitions and the specific prohibitions in subsection B of this section apply to each user introducing pollutants into a POTW whether or not the user is subject to other national pretreatment standards or any national, state, or local pretreatment requirements.
2. Affirmative defenses. A user shall have an affirmative defense in any action brought against it alleging a violation of the general prohibitions established in subdivision A 1 of this section and the specific prohibitions in subdivisions B 3, 4, 5, 6, and 7 of this section where the user can demonstrate that:
a. It did not know or have reason to know that its discharge, alone or in conjunction with a discharge or discharges from other sources, would cause pass through or interference; and
b. (1) A local limit designed to prevent pass through or interference or both, as the case may be, was developed in accordance with subsection C of this section for each pollutant in the user's discharge that caused pass through or interference, and the user was in compliance with each such local limit directly prior to and during the pass through or interference; or
(2) If a local limit designed to prevent pass through or interference or both, as the case may be, has not been developed in accordance with subsection C of this section for the pollutant or pollutants that caused the pass through or interference, the user's discharge directly prior to and during the pass through or interference did not change substantially in nature or constituents from the user's prior discharge activity when the POTW was regularly in compliance with the POTW's VPDES permit requirements and, in the case of interference, applicable requirements for sewage sludge use or disposal.
B. Specific prohibitions. In addition, the following pollutants shall not be introduced into a POTW:
1. Pollutants which create a fire or explosion hazard in the POTW, including, but not limited to, wastestreams with a closed cup flashpoint of less than 140°F or 60°C using the test methods specified in 40 CFR 261.21
(2005);2. Pollutants which will cause corrosive structural damage to the POTW, but in no case discharges with pH lower than 5.0, unless the works is specifically designed to accommodate such discharges;
3. Solid or viscous pollutants in amounts which will cause obstruction to the flow in the POTW resulting in interference;
4. Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a discharge at a flow rate or pollutant concentration which will cause interference with the POTW;
5. Heat in amounts which will inhibit biological activity in the POTW resulting in interference, but in no case heat in such quantities that the temperature at the POTW treatment plant exceeds 40°C (104°F) unless the director, upon request of the POTW, approves alternate temperature limits;
6. Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through;
7. Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems; or
8. Any trucked or hauled pollutants, except at discharge points designated by the POTW.
C. When specific limits must be developed by POTW.
1. Each POTW developing a POTW pretreatment program pursuant to 9VAC25-31-800 shall develop and enforce specific limits to implement the prohibitions listed in subdivisions A 1 and subsection B of this section. Each POTW with an approved pretreatment program shall continue to develop these limits as necessary and effectively enforce such limits.
2. All other POTW's shall, in cases where pollutants contributed by users result in interference, pass through or water quality standards violations and such violation is likely to recur, develop and enforce specific effluent limits for industrial users, and all other users, as appropriate, which, together with appropriate changes in the POTW treatment plant's facilities or operation, are necessary to ensure renewed and continued compliance with the POTW's VPDES permit or sludge use or disposal practices.
3. Specific effluent limits shall not be developed and enforced without individual notice to persons or groups who have requested such notice and an opportunity to respond.
4. All POTWs with approved pretreatment programs shall provide a written technical evaluation of the need to revise their local limits within one year of reissuance of VPDES permits for applicable treatment works, or within one year of VPDES permit modifications resulting in significant changes in VPDES permit limitations, POTW pretreatment operations, or POTW sludge disposal methods.
5. POTWs may develop Best Management Practices (BMPs) to implement subdivisions 1 and 2 of this subsection. Such BMPs shall be considered local limits and pretreatment standards for the purposes of this Part and § 307(d) of the Act.
D. Local limits. Where specific prohibitions or limits on pollutants or pollutant parameters are developed by a POTW in accordance with subsection C of this section, such limits shall be deemed pretreatment standards for the purposes of § 307(d) of the CWA.
E. EPA and state enforcement actions under the law and § 309(f) of the CWA. If, within 30 days after notice of an interference or pass through violation has been sent by the director or EPA to the POTW, and to persons or groups who have requested such notice, the POTW fails to commence appropriate enforcement action to correct the violation, the director or EPA may take appropriate enforcement action under the authority provided by the law and in § 309(f) of the CWA.
9VAC25-31-780. National pretreatment standards: categorical standards.
National pretreatment standards included in the regulations incorporated by reference in 9VAC25-31-30, unless specifically noted otherwise, shall be in addition to all applicable pretreatment standards and requirements set forth in this part.
A. Category determination request.
1. Application deadline within 60 days after the effective date of a pretreatment standard for a subcategory under which an industrial user may be included, the industrial user or POTW may request that the Water Management Division Director or director, as appropriate, provide written certification on whether the industrial user falls within that particular subcategory. If an existing industrial user adds or changes a process or operation which may be included in a subcategory, the existing industrial user must request this certification prior to commencing discharge from the added or changed processes or operation. A new source must request this certification prior to commencing discharge. Where a certification is submitted by a POTW, the POTW shall notify any affected industrial user of such submission. The industrial user may provide written comments on the POTW submission to the Water Management Division Director or director, as appropriate, within 30 days of notification.
2. Contents of application each request shall contain a statement:
a. Describing which subcategories might be applicable; and
b. Citing evidence and reasons why a particular subcategory is applicable and why others are not applicable. Any person signing the application statement submitted pursuant to this section shall make the following certification:
"I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations."
3. Deficient requests. The Water Management Division Director or director will only act on written requests for determinations that contain all of the information required. Persons who have made incomplete submissions will be notified by the Water Management Division Director or director that their requests are deficient and, unless the time period is extended, will be given 30 days to correct the deficiency. If the deficiency is not corrected within 30 days or within an extended period allowed by the Water Management Division Director or the director, the request for a determination shall be denied.
4. Final decision.
a. When the Water Management Division Director or director receives a submittal he will, after determining that it contains all of the information required by subdivision 2 of this subsection, consider the submission, any additional evidence that may have been requested, and any other available information relevant to the request. The Water Management Division Director or director will then make a written determination of the applicable subcategory and state the reasons for the determination.
b. Where the request is submitted to the director, the director shall forward the determination described in this subdivision to the Water Management Division Director who may make a final determination. If the Water Management Division Director does not modify the director's decision within 60 days after receipt thereof, or if the Water Management Division Director waives receipt of the determination, the director's decision is final.
c. Where the request is submitted by the industrial user or POTW to the Water Management Division Director or where the Water Management Division Director elects to modify the director's decision, the Water Management Division Director's decision will be final.
d. The director shall send a copy of the determination to the affected industrial user and the POTW.
5. Requests for public hearing or legal decision. Within 30 days following the date of receipt of notice of the final determination as provided for by subdivision A 4 d of this section, the requester may submit a petition to reconsider or contest the decision to the regional administrator who shall act on such petition expeditiously and state the reasons for his determination in writing.
B. Deadline for compliance with categorical standards. Compliance by existing sources with categorical pretreatment standards shall be within three years of the date the standard is effective unless a shorter compliance time is specified in the regulations incorporated by reference in 9VAC25-31-30. Direct dischargers with VPDES permits modified or reissued to provide a variance pursuant to § 301(i)(2) of the CWA shall be required to meet compliance dates set in any applicable categorical pretreatment standard. Existing sources which become industrial users subsequent to promulgation of an applicable categorical pretreatment standard shall be considered existing industrial users except where such sources meet the definition of a new source as defined in 9VAC25-31-10. New sources shall install and have in operating condition, and shall "start up" all pollution control equipment required to meet applicable pretreatment standards before beginning to discharge. Within the shortest feasible time (not to exceed 90 days), new sources must meet all applicable pretreatment standards.
C. 1. Concentration and mass limits pollutant discharge limits in categorical pretreatment standards will be expressed either as concentration or mass limits. Wherever possible, where concentration limits are specified in standards, equivalent mass limits will be provided so that local, state or federal authorities responsible for enforcement may use either concentration or mass limits. Limits in categorical pretreatment standards shall apply to the effluent of the process regulated by the standard, or as otherwise specified by the standard.
2. When the limits in a categorical pretreatment standard are expressed only in terms of mass of pollutant per unit of production, the control authority may convert the limits to equivalent limitations expressed either as mass of pollutant discharged per day or effluent concentration for purposes of calculating effluent limitations applicable to individual industrial users.
3. A control authority calculating equivalent mass-per-day limitations under subdivision 2 of this subsection shall calculate such limitations by multiplying the limits in the standard by the industrial user's average rate of production. This average rate of production shall be based not upon the designed production capacity but rather upon a reasonable measure of the industrial user's actual long-term daily production, such as the average daily production during a representative year. For new sources, actual production shall be estimated using projected production.
4. A control authority calculating equivalent concentration limitations under subdivision 2 of this subsection shall calculate such limitations by dividing the mass limitations derived under subdivision 3 of this subsection by the average daily flow rate of the industrial user's regulated process wastewater. This average daily flow rate shall be based upon a reasonable measure of the industrial user's actual long-term average flow rate, such as the average daily flow rate during the representative year.
5. When the limits in a categorical pretreatment standard are expressed only in terms of pollutant concentrations, an industrial user may request that the control authority convert the limits to equivalent mass limits. The determination to convert concentration limits to mass limits is within the discretion of the control authority. The control authority may establish equivalent mass limits only if the industrial user meets all the following conditions in subdivisions 5 a (1) through (5) of this subsection as follows.
a. To be eligible for equivalent mass limits, the industrial user must:
(1) Employ, or demonstrate that it will employ, water conservation methods and technologies that substantially reduce water use during the term of its control mechanism;
(2) Currently use control and treatment technologies adequate to achieve compliance with the applicable categorical pretreatment standard, and not have used dilution as a substitute for treatment;
(3) Provide sufficient information to establish the facility's actual average daily flow rate for all wastestreams, based on data from a continuous effluent flow monitoring device, as well as the facility's long-term average production rate. Both the actual average daily flow rate and the long-term average production rate must be representative of current operating conditions;
(4) Not have daily flow rates, production levels, or pollutant levels that vary so significantly that equivalent mass limits are not appropriate to control the discharge; and
(5) Have consistently complied with all applicable categorical pretreatment standards during the period prior to the industrial user's request for equivalent mass limits.
b. An industrial user subject to equivalent mass limits must:
(1) Maintain and effectively operate control and treatment technologies adequate to achieve compliance with the equivalent mass limits;
(2) Continue to record the facility's flow rates through the use of a continuous effluent flow monitoring device;
(3) Continue to record the facility's production rates and notify the control authority whenever production rates are expected to vary by more than 20% from its baseline production rates determined in subdivision 5 a (3) of this subsection. Upon notification of a revised production rate, the Control Authority must reassess the equivalent mass limit and revise the limit as necessary to reflect changed conditions at the facility; and
(4) Continue to employ the same or comparable water conservation methods and technologies as those implemented pursuant to subdivision 5 a (1) of this subsection so long as it discharges under an equivalent mass limit.
c. A control authority that chooses to establish equivalent mass limits:
(1) Must calculate the equivalent mass limit by multiplying the actual average daily flow rate of the regulated process(es) of the industrial user by the concentration-based daily maximum and monthly average standard for the applicable categorical pretreatment standard and the appropriate unit conversion factor;
(2) Upon notification of a revised production rate, must reassess the equivalent mass limit and recalculate the limit as necessary to reflect changed conditions at the facility; and
(3) May retain the same equivalent mass limit in subsequent control mechanism terms if the industrial user's actual average daily flow rate was reduced solely as a result of the implementation of water conservation methods and technologies, and the actual average daily flow rates used in the original calculation of the equivalent mass limit were not based on the use of dilution as a substitute for treatment pursuant to subdivision 5 d of this subsection. The industrial user must also be in compliance with 9VAC25-31-890 (regarding the prohibition of bypass).
d. The control authority may not express limits in terms of mass for pollutants such as pH, temperature, radiation, or other pollutants which cannot appropriately be expressed as mass.
6. The control authority may convert the mass limits of the categorical pretreatment standards at 40 CFR Parts 414, 419, and 455 to concentration limits for purposes of calculating limitations applicable to individual industrial users under the following conditions: when converting such limits to concentration limits, the control authority must use the concentrations listed in the applicable subparts of 40 CFR Parts 414, 419, and 455 and document that dilution is not being substituted for treatment as prohibited by subsection D of this section.
7. Equivalent limitations calculated in accordance with subdivisions 3 4, 5 and 6 of this subsection are deemed pretreatment standards for the purposes of § 307(d) of the CWA and this part. The control authority must document how the equivalent limits were derived and make this information publicly available. Once incorporated into its control mechanism, the individual user must comply with the equivalent limitations in lieu of the promulgated categorical standards from which the equivalent limitations were derived.
8. Many categorical pretreatment standards specify one limit for calculating maximum daily discharge limitations and a second limit for calculating maximum monthly average, or four-day average, limitations. Where such standards are being applied, the same production or flow figure shall be used in calculating both the average and the maximum equivalent limitation.
9. Any industrial user operating under a control mechanism incorporating equivalent mass or concentration limits calculated from a production based standard shall notify the control authority within two business days after the user has a reasonable basis to know that the production level will significantly change within the next calendar month. Any user not notifying the control authority of such anticipated change will be required to meet the mass or concentration limits in its control mechanism that were based on the original estimate of the long term average production rate.
D. Dilution prohibited as substitute for treatment. Except where expressly authorized to do so by an applicable pretreatment standard or requirement, no industrial user shall ever increase the use of process water, or in any other way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with a pretreatment standard or requirement. The control authority may impose mass limitations on industrial users which are using dilution to meet applicable pretreatment standards or requirements, or in other cases where the imposition of mass limitations is appropriate.
E. Combined wastestream formula. Where process effluent is mixed prior to treatment with wastewaters other than those generated by the regulated process, fixed alternative discharge limits may be derived by the control authority, or by the industrial user with the written concurrence of the control authority. These alternative limits shall be applied to the mixed effluent. When deriving alternative categorical limits, the control authority or industrial user shall calculate both an alternative daily maximum value using the daily maximum values specified in the appropriate categorical pretreatment standard or standards and an alternative consecutive sampling day average value using the monthly average values specified in the appropriate categorical pretreatment standards. The industrial user shall comply with the alternative daily maximum and monthly average limits fixed by the control authority until the control authority modifies the limits or approves an industrial user modification request. Modification is authorized whenever there is a material or significant change in the values used in the calculation to fix alternative limits for the regulated pollutant. An industrial user must immediately report any such material or significant change to the control authority. Where appropriate new alternative categorical limits shall be calculated within 30 days.
1. Alternative limit calculation. For purposes of these formulas, the "average daily flow" means a reasonable measure of the average daily flow for a 30-day period. For new sources, flows shall be estimated using projected values. The alternative limit for a specified pollutant will be derived by the use of either of the following formulas:
a. Alternative concentration limit.
where:
CT = the alternative concentration limit for the combined wastestream.
Ci = the categorical pretreatment standard concentration limit for a pollutant in the regulated stream i.
Fi = the average daily flow (at least a 30-day average) of stream i to the extent that it is regulated for such pollutant.
FD = the average daily flow (at least a 30-day average) from: (i) boiler blowdown streams, noncontact cooling streams, stormwater streams, and demineralizer backwash streams; provided, however, that where such streams contain a significant amount of a pollutant, and the combination of such streams, prior to treatment, with an industrial user's regulated process wastestreams will result in a substantial reduction of that pollutant, the control authority, upon application of the industrial user, may exercise its discretion to determine whether such streams should be classified as diluted or unregulated. In its application to the control authority, the industrial user must provide engineering, production, sampling and analysis and such other information so that the control authority can make its determination; (ii) sanitary wastestreams where such streams are not regulated by a categorical pretreatment standard; or (iii) any process wastestreams which were or could have been entirely exempted from categorical pretreatment standards for one or more of the following reasons (see Appendix D of 40 CFR Part
403 (2005))403):(1) The pollutants of concern are not detectable in the effluent from the industrial user;
(2) The pollutants of concern are present only in trace amounts and are neither causing nor likely to cause toxic effects;
(3) The pollutants of concern are present in amounts too small to be effectively reduced by technologies known to the administrator; or
(4) The wastestream contains only pollutants which are compatible with the POTW.
FT = The average daily flow (at least a 30-day average) through the combined treatment facility (includes Fi, FD and unregulated streams).
N = The total number of regulated streams.
b. Alternative mass limit.
where:
MT = the alternative mass limit for a pollutant in the combined wastestream.
Mi = the categorical pretreatment standard mass limit for a pollutant in the regulated stream i (the categorical pretreatment mass limit multiplied by the appropriate measure of production).
Fi = the average flow (at least a 30-day average) of stream i to the extent that it is regulated for such pollutant.
FD = the average daily flow (at least a 30-day average) from: (i) boiler blowdown streams, noncontact cooling streams, stormwater streams, and demineralizer backwash streams; provided, however, that where such streams contain a significant amount of a pollutant, and the combination of such streams, prior to treatment, with an industrial user's regulated process wastestreams will result in a substantial reduction of that pollutant, the control authority, upon application of the industrial user, may exercise its discretion to determine whether such streams should be classified as diluted or unregulated. In its application to the control authority, the industrial user must provide engineering, production, sampling and analysis and such other information so that the control authority can make its determination; (ii) sanitary wastestreams where such streams are not regulated by a categorical pretreatment standard; or (iii) any process wastestreams which were or could have been entirely exempted from categorical pretreatment standards for one or more of the following reasons (see Appendix D of 40 CFR Part
403 (2005))403):(1) The pollutants of concern are not detectable in the effluent from the industrial user;
(2) The pollutants of concern are present only in trace amounts and are neither causing nor likely to cause toxic effects;
(3) The pollutants of concern are present in amounts too small to be effectively reduced by technologies known to the administrator; or
(4) The wastestream contains only pollutants which are compatible with the POTW.
FT = The average flow (at least a 30-day average) through the combined treatment facility (includes Fi, FD and unregulated streams).
N = The total number of regulated streams.
2. An alternative pretreatment limit may not be used if the alternative limit is below the analytical detection limit for any of the regulated pollutants.
3. Self-monitoring required to insure compliance with the alternative categorical limit shall be conducted in accordance with the requirements of 9VAC25-31-840 G.
4. Where a treated regulated process wastestream is combined prior to treatment with wastewaters other than those generated by the regulated process, the industrial user may monitor either the segregated process wastestream or the combined wastestream for the purpose of determining compliance with applicable pretreatment standards. If the industrial user chooses to monitor the segregated process wastestream, it shall apply the applicable categorical pretreatment standard. If the user chooses to monitor the combined wastestream, it shall apply an alternative discharge limit calculated using the combined wastestream formula as provided in this section. The industrial user may change monitoring points only after receiving approval from the control authority. The control authority shall ensure that any change in an industrial user's monitoring point or points will not allow the user to substitute dilution for adequate treatment to achieve compliance with applicable standards.
9VAC25-31-790. Removal credits.
A. General.
1. Definitions for the purpose of this section:
"Removal" means a reduction in the amount of a pollutant in the POTW's effluent or alteration of the nature of a pollutant during treatment at the POTW. The reduction or alteration can be obtained by physical, chemical or biological means and may be the result of specifically designed POTW capabilities or may be incidental to the operation of the treatment system. Removal as used in this subpart shall not mean dilution of a pollutant in the POTW.
"Sludge requirements" means the following statutory provisions and regulations or permits issued thereunder (or more stringent Virginia or local regulations): § 405 of the CWA; the Solid Waste Disposal Act (SWDA) (42 USC § 6901 et seq.) (including Title II more commonly referred to as the Resource Conservation Recovery Act (RCRA) (42 USC § 6901 et seq.) and Virginia regulations contained in any Virginia sludge management plan prepared pursuant to Subtitle D of SWDA); the Clean Air Act (42 USC § 4701 et seq.); the Toxic Substances Control Act (15 USC § 2601 et seq.); and the Marine Protection, Research and Sanctuaries Act (33 USC § 1401 et seq.).
2. General. Any POTW receiving wastes from an industrial user to which a categorical pretreatment standards applies may, at its discretion and subject to the conditions of this section, grant removal credits to reflect removal by the POTW of pollutants specified in the categorical pretreatment standards. The POTW may grant a removal credit equal to or, at its discretion, less than its consistent removal rate. Upon being granted a removal credit, each affected industrial user shall calculate its revised discharge limits in accordance with subdivision 4 of this subsection. Removal credits may only be given for indicator or surrogate pollutants regulated in a categorical pretreatment standard if the categorical pretreatment statement so specifies.
3. Conditions for authorization to give removal credits. A POTW is authorized to give removal credits only if the following conditions are met;
a. Application. The POTW applies for, and receives, authorization from the director to give a removal credit in accordance with the requirements and procedures specified in subsection E of this section;
b. Consistent removal determination. The POTW demonstrates and continues to achieve consistent removal of the pollutant in accordance with subsection B of this section;
c. POTW local pretreatment program. The POTW has an approved pretreatment program in accordance with and to the extent required by this part; provided, however, a POTW which does not have an approved pretreatment program may, pending approval of such a program, conditionally give credits as provided in subsection D of this section;
d. Sludge requirements. The granting of removal credits will not cause the POTW to violate the local, state and federal sludge requirements which apply to the sludge management method chosen by the POTW. Alternatively, the POTW can demonstrate to the director that even though it is not presently in compliance with applicable sludge requirements, it will be in compliance when the industrial users to whom the removal credit would apply is required to meet its categorical pretreatment standards as modified by the removal credit. If granting removal credits forces a POTW to incur greater sludge management costs than would be incurred in the absence of granting removal costs, the additional sludge management costs will not be eligible for EPA grant assistance. Removal credits may be made available for the following pollutants:
(1) For any pollutant listed in Appendix G-I of the regulation incorporated by reference in 9VAC25-31-750 for the use or disposal practice employed by the POTW, when the requirements of Part VI of this chapter for that practice are met;
(2) For any pollutant listed in Appendix G-II of the regulation incorporated by reference in 9VAC25-31-750 for the use or disposal practice employed by the POTW when the concentration for a pollutant listed in Appendix G-II of the regulation incorporated by reference in 9VAC25-31-750 in the sewage sludge that is used or disposed does not exceed the concentration for the pollutant in Appendix G-II of the regulation incorporated by reference in 9VAC25-31-750; and
(3) For any pollutant in sewage sludge when the POTW disposes all of its sewage sludge in a municipal solid waste landfill that meets the criteria in the Code of Virginia and the Solid Waste Management Regulations, 9VAC20-81;
e. VPDES permit limitations. The granting of removal credits will not cause a violation of the POTW's permit limitations or conditions. Alternatively, the POTW can demonstrate to the director that even though it is not presently in compliance with applicable limitations and conditions in its VPDES permit, it will be in compliance when the industrial user or users to whom the removal credit would apply is required to meet its categorical pretreatment standard or standards, as modified by the removal credit provision.
4. Calculation of revised discharge limits. Revised discharge limits for a specific pollutant shall be derived by use of the following formula:
y =
x
1 - r
where:
x = pollutant discharge limit specified in the applicable categorical pretreatment standard
r = removal credit for that pollutant as established under subsection B of this section (percentage removal expressed as a proportion, i.e., a number between 0 and 1)
y = revised discharge limit for the specified pollutant (expressed in same units as x)
B. Establishment of removal credits; demonstration of consistent removal.
1. Definition of "consistent removal." "Consistent removal" means the average of the lowest 50% of the removal measured according to subdivision 2 of this subsection. All sample data obtained for the measured pollutant during the time period prescribed in subdivision 2 of this subsection must be reported and used in computing consistent removal. If a substance is measurable in the influent but not in the effluent, the effluent level may be assumed to be the limit of measurement, and those data may be used by the POTW at its discretion and subject to approval by the director. If the substance is not measurable in the influent, the data may not be used. Where the number of samples with concentrations equal to or above the limit of measurement is between eight and 12, the average of the lowest six removals shall be used. If there are less than eight samples with concentrations equal to or above the limit of measurement, the director may approve alternate means for demonstrating consistent removal. The term "measurement" refers to the ability of the analytical method or protocol to quantify as well as identify the presence of the substance in question.
2. Consistent removal data. Influent and effluent operational data demonstrating consistent removal or other information, as provided for in subdivision 1 of this subsection, which demonstrates consistent removal of the pollutants for which discharge limit revisions are proposed. This data shall meet the following requirements:
a. Representative data; seasonal. The data shall be representative of yearly and seasonal conditions to which the POTW is subjected for each pollutant for which a discharge limit revision is proposed;
b. Representative data; quality and quantity. The data shall be representative of the quality and quantity of normal effluent and influent flow if such data can be obtained. If such data are unobtainable, alternate data or information may be presented for approval to demonstrate consistent removal as provided for in subdivision 1 of this subsection;
c. Sampling procedures: composite.
(1) The influent and effluent operational data shall be obtained through 24-hour flow-proportional composite samples. Sampling may be done manually or automatically, and discretely or continuously. For discrete sampling, at least 12 aliquots shall be composited. Discrete sampling may be flow-proportioned either by varying the time interval between each aliquot or the volume of each aliquot. All composites must be flow proportional to each stream flow at time of collection of influent aliquot or to the total influent flow since the previous influent aliquot. Volatile pollutant aliquots must be combined in the laboratory immediately before analysis.
(2)(a) Twelve samples shall be taken at approximately equal intervals throughout one full year. Sampling must be evenly distributed over the days of the week so as to include no-workdays as well as workdays. If the director determines that this schedule will not be most representative of the actual operation of the POTW treatment plant, an alternative sampling schedule will be approved.
(b) In addition, upon the director's concurrence, a POTW may utilize an historical data base amassed prior to July 24, 1996, provide that such data otherwise meet the requirements of this paragraph. In order for the historical data base to be approved it must present a statistically valid description of daily, weekly and seasonal sewage treatment plant loadings and performance for at least one year.
(3) Effluent sample collection need not be delayed to compensate for hydraulic detention unless the POTW elects to include detention time compensation or unless the director requires detention time compensation. The director may require that each effluent sample be taken approximately one detention time later than the corresponding influent sample when failure to do so would result in an unrepresentative portrayal of actual POTW operation. The detention period is to be based on a 24-hour average daily flow value. The average daily flow used will be based upon the average of the daily flows during the same month of the previous year.
d. Sampling procedures: Grab. Where composite sampling is not an appropriate sampling technique, a grab sample or samples shall be taken to obtain influent and effluent operational data. Collection of influent grab samples should precede collection of effluent samples by approximately one detention period. The detention period is to be based on a 24-hour average daily flow value. The average daily flow used will be based upon the average of the daily flows during the same month of the previous year. Grab samples will be required, for example, where the parameters being evaluated are those, such as cyanide and phenol, which may not be held for any extended period because of biological, chemical or physical interactions which take place after sample collection and affect the results. A grab sample is an individual sample collected over a period of time not exceeding 15 minutes;
e. Analytical methods. The sampling referred to in subdivisions 2 a through d of this subsection and an analysis of these samples shall be performed in accordance with the techniques prescribed in 40 CFR Part 136
(2005)and amendments thereto. Where 40 CFR Part 136(2005)does not contain sampling or analytical techniques for the pollutant in question, or where the administrator determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analysis shall be performed using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the POTW or other parties, approved by the administrator; andf. Calculation of removal. All data acquired under the provisions of this section must be submitted to the department. Removal for a specific pollutant shall be determined either, for each sample, by measuring the difference between the concentrations of the pollutant in the influent and effluent of the POTW and expressing the difference as a percentage of the influent concentration, or, where such data cannot be obtained, removal may be demonstrated using other data or procedures subject to concurrence by the director as provided for in subdivision 1 of this subsection.
C. Provisional credits. For pollutants which are not being discharged currently (i.e., new or modified facilities, or production changes) the POTW may apply for authorization to give removal credits prior to the initial discharge of the pollutant. Consistent removal shall be based provisionally on data from treatability studies or demonstrated removal at other treatment facilities where the quality and quantity of influent are similar. Within 18 months after the commencement of discharge of pollutants in question, consistent removal must be demonstrated pursuant to the requirements of subsection B of this section. If, within 18 months after the commencement of the discharge of the pollutant in question, the POTW cannot demonstrate consistent removal pursuant to the requirements of subsection B of this section, the authority to grant provisional removal credits shall be terminated by the director and all industrial users to whom the revised discharge limits had been applied shall achieve compliance with the applicable categorical pretreatment standards within a reasonable time, not to exceed the period of time prescribed in the applicable categorical pretreatment standards, as may be specified by the director.
D. Exception to POTW pretreatment program requirement. A POTW required to develop a local pretreatment program by 9VAC25-31-800 may conditionally give removal credits pending approval of such a program in accordance with the following terms and conditions:
1. All industrial users who are currently subject to a categorical pretreatment standard and who wish conditionally to receive a removal credit must submit to the POTW the information required in 9VAC25-31-840 B 1 through 7 (except new or modified industrial users must only submit the information required by 9VAC25-31-840 B 1 through 6), pertaining to the categorical pretreatment standard as modified by the removal credit. The industrial users shall indicate what additional technology, if any, will be needed to comply with the categorical pretreatment standard or standards as modified by the removal credit;
2. The POTW must have submitted to the department an application for pretreatment program approval meeting the requirements of 9VAC25-31-800 and 9VAC25-31-810 in a timely manner, not to exceed the time limitation set forth in a compliance schedule for development of a pretreatment program included in the POTW's VPDES permit, but in no case later than July 1, 1983, where no permit deadline exists;
3. The POTW must:
a. Compile and submit data demonstrating its consistent removal in accordance with subsection B of this section;
b. Comply with the conditions specified in subdivision A 3 of this section; and
c. Submit a complete application for removal credit authority in accordance with subsection E of this section;
4. If a POTW receives authority to grant conditional removal credits and the director subsequently makes a final determination, after appropriate notice, that the POTW failed to comply with the conditions in subdivisions 2 and 3 of this subsection, the authority to grant conditional removal credits shall be terminated by the director and all industrial users to whom the revised discharge limits had been applied shall achieve compliance with the applicable categorical pretreatment standards within a reasonable time, not to exceed the period of time prescribed in the applicable categorical pretreatment standards, as may be specified by the director;
5. If a POTW grants conditional removal credits and the POTW or the director subsequently makes a final determination, after appropriate notice, that the industrial user or users failed to comply with the conditions in subdivision 1 of this subsection, the conditional credit shall be terminated by the POTW or the director for the noncomplying industrial user or users and the industrial user or users to whom the revised discharge limits had been applied shall achieve compliance with the applicable categorical pretreatment standards within a reasonable time, not to exceed the period of time prescribed in the applicable categorical pretreatment standards, as may be specified by the director. The conditional credit shall not be terminated where a violation of the provisions of this paragraph results from causes entirely outside of the control of the industrial user or users or the industrial user or users had demonstrated subsequential compliance; and
6. The director may elect not to review an application for conditional removal credit authority upon receipt of such application, in which case the conditionally revised discharge limits will remain in effect until reviewed by the director. This review may occur at any time in accordance with the procedures of 9VAC25-31-830, but in no event later than the time of any pretreatment program approval or any VPDES permit reissuance thereunder.
E. POTW application for authorization to give removal credits and director review.
1. Who must apply. Any POTW that wants to give a removal credit must apply for authorization from the director.
2. To whom application is made. An application for authorization to give removal credits (or modify existing ones) shall be submitted by the POTW to the department.
3. When to apply. A POTW may apply for authorization to give or modify removal credits at any time.
4. Contents of the application. An application for authorization to give removal credits must be supported by the following information:
a. List of pollutants. A list of pollutants for which removal credits are proposed;
b. Consistent removal data. The data required pursuant to subsection B of this section;
c. Calculation of revised discharge limits. Proposed revised discharge limits for each affected subcategory of industrial users calculated in accordance with subdivision A 4 of this section;
d. Local pretreatment program certification. A certification that the POTW has an approved local pretreatment program or qualifies for the exception to this requirement found at subsection D of this section;
e. Sludge management certification. A specific description of the POTW's current methods of using or disposing of its sludge and a certification that the granting of removal credits will not cause a violation of the sludge requirements identified in subdivision A 3 d of this section; and
f. VPDES permit limit certification. A certification that the granting of removal credits will not cause a violation of the POTW's VPDES permit limits and conditions as required in subdivision A 3 e of this section.
5. Director review. The director shall review the POTW's application for authorization to give or modify removal credits in accordance with the procedures of 9VAC25-31-830 and shall, in no event, have more than 180 days from public notice of an application to complete review.
6. Nothing in this part precludes an industrial user or other interested party from assisting the POTW in preparing and presenting the information necessary to apply for authorization.
F. Continuation and withdrawal of authorization.
1. Effect of authorization. Once a POTW has received authorization to grant removal credits for a particular pollutant regulated in a categorical pretreatment standard it may automatically extend that removal credit to the same pollutant when it is regulated in other categorical standards, unless granting the removal credit will cause the POTW to violate the sludge requirements identified in subdivision A 3 d of this section or its VPDES permit limits and conditions as required by subdivision A 3 e of this section. If a POTW elects at a later time to extend removal credits to a certain categorical pretreatment standard, industrial subcategory or one or more industrial users that initially were not granted removal credits, it must notify the department.
2. Inclusion in POTW permit. Once authority is granted, the removal credits shall be included in the POTW's VPDES permit as soon as possible and shall become an enforceable requirement of the POTW's VPDES permit. The removal credits will remain in effect for the term of the POTW's VPDES permit, provided the POTW maintains compliance with the conditions specified in subdivision 4 of this subsection.
3. Compliance monitoring. Following authorization to give removal credits, a POTW shall continue to monitor and report on (at such intervals as may be specified by the director, but in no case less than once per year) the POTW's removal capabilities. A minimum of one representative sample per month during the reporting period is required, and all sampling data must be included in the POTW's compliance report.
4. Modification or withdrawal of removal credits.
a. Notice of POTW. The director shall notify the POTW if, on the basis of pollutant removal capability reports received pursuant to subdivision 3 of this subsection or other relevant information available to it, the director determines:
(1) That one or more of the discharge limit revisions made by the POTW, of the POTW itself, no longer meets the requirements of this section, or
(2) That such discharge limit revisions are causing a violation of any conditions or limits contained in the POTW's VPDES Permit.
b. Corrective action. If appropriate corrective action is not taken within a reasonable time, not to exceed 60 days unless the POTW or the affected industrial users demonstrate that a longer time period is reasonably necessary to undertake the appropriate corrective action, the director shall either withdraw such discharge limits or require modifications in the revised discharge limits.
c. Public notice of withdrawal or modification. The director shall not withdraw or modify revised discharge limits unless it shall first have notified the POTW and all industrial users to whom revised discharge limits have been applied, and made public, in writing, the reasons for such withdrawal or modification, and an opportunity is provided for a public hearing. Following such notice and withdrawal or modification, all industrial users to whom revised discharge limits had been applied, shall be subject to the modified discharge limits or the discharge limits prescribed in the applicable categorical pretreatment standards, as appropriate, and shall achieve compliance with such limits within a reasonable time (not to exceed the period of time prescribed in the applicable categorical pretreatment standards) as may be specified by the director.
G. Removal credits in state-run pretreatment programs. Where the director elects to implement a local pretreatment program in lieu of requiring the POTW to develop such a program the POTW will not be required to develop a pretreatment program as a precondition to obtaining authorization to give removal credits. The POTW will, however, be required to comply with the other conditions of subdivision A 3 of this section.
H. Compensation for overflow. For the purpose of this section, "overflow" means the intentional or unintentional diversion of flow from the POTW before the POTW treatment plant. POTWs which at least once annually overflow untreated wastewater to receiving waters may claim consistent removal of a pollutant only by complying with either subdivision 1 or 2 of this subsection. However, this subsection shall not apply where industrial users can demonstrate that overflow does not occur between the industrial users and the POTW treatment plant:
1. The industrial user provides containment or otherwise ceases or reduces discharges from the regulated processes which contain the pollutant for which an allowance is requested during all circumstances in which an overflow event can reasonably be expected to occur at the POTW or at a sewer to which the industrial user is connected. Discharges must cease or be reduced, or pretreatment must be increased, to the extent necessary to compensate for the removal not being provided by the POTW. Allowances under this provision will only be granted where the POTW submits to the department evidence that:
a. All industrial users to which the POTW proposes to apply this provision have demonstrated the ability to contain or otherwise cease or reduce, during circumstances in which an overflow event can reasonably be expected to occur, discharges from the regulated processes which contain pollutants for which an allowance is requested;
b. The POTW has identified circumstances in which an overflow event can reasonably be expected to occur, and has a notification or other viable plan to insure that industrial users will learn of an impending overflow in sufficient time to contain, cease or reduce discharging to prevent untreated overflows from occurring. The POTW must also demonstrate that it will monitor and verify the data required in subdivision 1 c of this subsection, to insure that industrial users are containing, ceasing or reducing operations during POTW system overflow; and
c. All industrial users to which the POTW proposes to apply this provision have demonstrated the ability and commitment to collect and make available, upon request by the POTW, the director or EPA Regional Administrator, daily flow reports or other data sufficient to demonstrate that all discharges from regulated processes containing the pollutant for which the allowance is requested were contained, reduced or otherwise ceased, as appropriate, during all circumstances in which an overflow event was reasonably expected to occur; or
2. a. The consistent removal claimed is reduced pursuant to the following equation:
rc =
rm 8760 - z
8760
where:
rm = POTW's consistent removal rate for that pollutant as established under subsections A 1 and B 2 of this section
rc = removal corrected by the overflow factor
Z = hours per year that overflow occurred between the industrial user or users and the POTW treatment plant, the hours either to be shown in the POTW's current VPDES permit application or the hours, as demonstrated by verifiable techniques, that a particular industrial user's discharge overflows between the industrial user and the POTW treatment plant.
b. The POTW is complying with all VPDES permit requirements and any additional requirements in any order or decree, issued pursuant to the Clean Water Act affecting combined sewer outflows. These requirements include, but are not limited to, any combined sewer overflow requirements that conform to the Combined Sewer Overflow Control Policy.
9VAC25-31-800. Pretreatment program requirements: development and implementation by POTW.
A. POTWs required to develop a pretreatment program. Any POTW (or combination of POTWs operated by the same authority) with a total design flow greater than five million gallons per day (mgd) and receiving from industrial users pollutants which pass through or interfere with the operation of the POTW or are otherwise subject to pretreatment standards will be required to establish a POTW pretreatment program unless the director exercises his or her option to assume local responsibilities. The regional administrator or director may require that a POTW with a design flow of five mgd or less develop a POTW pretreatment program if he finds that the nature or volume of the industrial influent, treatment process upsets, violations of POTW effluent limitations, contamination of municipal sludge, violations of water quality standards, or other circumstances warrant in order to prevent interference with the POTW or pass through.
B. Deadline for program approval. POTWs identified as being required to develop a POTW pretreatment program under subsection A of this section shall develop and submit such a program for approval as soon as possible, but in no case later than one year after written notification from the director of such identification. The approved program shall be in operation within two years of the effective date of the permit. The POTW pretreatment program shall meet the criteria set forth in subsection F of this section and shall be administered by the POTW to ensure compliance by industrial users with applicable pretreatment standards and requirements.
C. Incorporation of approved programs in permits. A POTW may develop an appropriate POTW pretreatment program any time before the time limit set forth in subsection B of this section. The POTW's VPDES permit will be reissued or modified to incorporate the approved program as enforceable conditions of the permit. The modification of a POTW's VPDES permit for the purposes of incorporating a POTW pretreatment program approved in accordance with the procedures in 9VAC25-31-830 shall be deemed a minor permit modification subject to the procedures in 9VAC25-31-400.
D. Incorporation of compliance schedules in permits. (Reserved.)
E. Cause for revocation and reissuance or modification of permits. Under the authority of the law and § 402 (b)(1)(C) of the CWA, the director may modify, or alternatively, revoke and reissue a POTW's permit in order to:
1. Put the POTW on a compliance schedule for the development of a POTW pretreatment program where the addition of pollutants into a POTW by an industrial user or combination of industrial users presents a substantial hazard to the functioning of the treatment works, quality of the receiving waters, human health, or the environment;
2. Coordinate the issuance of § 201 construction grant with the incorporation into a permit of a compliance schedule for POTW pretreatment program;
3. Incorporate a modification of the permit approved under § 301(h) or § 301(i) of the CWA;
4. Incorporate an approved POTW pretreatment program in the POTW permit;
5. Incorporate a compliance schedule for the development of a POTW pretreatment program in the POTW permit; or
6. Incorporate the removal credits (established under 9VAC25-31-790) in the POTW permit.
F. POTW pretreatment requirements. A POTW pretreatment program must be based on the following legal authority and include the following procedures. These authorities and procedures shall at all times be fully and effectively exercised and implemented.
1. Legal authority. The POTW shall operate pursuant to legal authority enforceable in federal, state or local courts, which authorizes or enables the POTW to apply and to enforce the requirements of §§ 307(b), (c) and (d), and 402(b)(8) of the CWA and any regulations implementing those sections. Such authority may be contained in a statute or ordinances which the POTW is authorized to enact, enter into or implement, and which are authorized by state law. At a minimum, this legal authority shall enable the POTW to:
a. Deny or condition new or increased contributions of pollutants, or changes in the nature of pollutants, to the POTW by industrial users where such contributions do not meet applicable pretreatment standards and requirements or where such contributions would cause the POTW to violate its VPDES permit.
b. Require compliance with applicable pretreatment standards and requirements by industrial users.
c. Control through permit, or order the contribution to the POTW by each industrial user to ensure compliance with applicable pretreatment standards and requirements. In the case of industrial users identified as significant under 9VAC25-31-10, this control shall be achieved through individual permits or equivalent individual control mechanisms issued to each such user except as follows:
(1)(a) At the discretion of the POTW, this control may include use of general control mechanisms if the following conditions are met. All of the facilities to be covered must:
(i) Involve the same or substantially similar types of operations;
(ii) Discharge the same types of wastes;
(iii) Require the same effluent limitations;
(iv) Require the same or similar monitoring; and
(v) In the opinion of the POTW, be more appropriately controlled under a general control mechanism than under individual control mechanisms.
(b) To be covered by the general control mechanism, the significant industrial user must file a written request for coverage that identifies its contact information, production processes, the types of wastes generated, the location for monitoring all wastes covered by the general control mechanism, any requests in accordance with 9VAC25-31-840 E 2 for a monitoring waiver for a pollutant neither present nor expected to be present in the discharge, and any other information the POTW deems appropriate. A monitoring waiver for a pollutant neither present nor expected to be present in the discharge is not effective in the general control mechanism until after the POTW has provided written notice to the significant industrial user that such a waiver request has been granted in accordance with 9VAC25-31-840 E 2. The POTW must retain a copy of the general control mechanism, documentation to support the POTW's determination that a specific significant industrial user meets the criteria in subdivisions 1 c (1) (a) (i) through (v) of this subsection, and a copy of the user's written request for coverage for three years after the expiration of the general control mechanism. A POTW may not control a significant industrial user through a general control mechanism where the facility is subject to production-based categorical pretreatment standards or categorical pretreatment standards expressed as mass of pollutant discharged per day or for industrial users whose limits are based on the Combined Wastestream Formula or Net/Gross calculations (9VAC25-31-780 E and 9VAC25-31-870).
(2) Both individual and general control mechanisms must be enforceable and contain, at a minimum, the following conditions:
(a) Statement of duration (in no case more than five years);
(b) Statement of nontransferability without, at a minimum, prior notification to the POTW and provision of a copy of the existing control mechanism to the new owner or operator;
(c) Effluent limits, including Best Management Practices, based on applicable general pretreatment standards in this part, categorical pretreatment standards, local limits, and the law;
(d) Self-monitoring, sampling, reporting, notification and recordkeeping requirements, including an identification of the pollutants to be monitored (including the process for seeking a waiver for a pollutant neither present nor expected to be present in the discharge in accordance with 9VAC25-31-840 E 2, or a specific waiver pollutant in the case of an individual control mechanism), sampling location, sampling frequency, and sample type, based on the applicable general pretreatment standards in this part, categorical pretreatment standards, local limits, and the law;
(e) Statement of applicable civil and criminal penalties for violation of pretreatment standards and requirements; and any applicable compliance schedules, which may not extend beyond applicable federal deadlines.
(f) Requirements to control slug discharges, if determined by the POTW to be necessary.
d. Require:
(1) The development of a compliance schedule by each industrial user for the installation of technology required to meet applicable pretreatment standards and requirements; and
(2) The submission of all notices and self-monitoring reports from industrial users as are necessary to assess and ensure compliance by industrial users with pretreatment standards and requirements, including but not limited to the reports required in 9VAC25-31-840.
e. Carry out all inspection, surveillance and monitoring procedures necessary to determine, independent of information supplied by industrial users, compliance or noncompliance with applicable pretreatment standards and requirements by industrial users. Representatives of the POTW shall be authorized to enter any premises of any industrial user in which a discharge source or treatment system is located or in which records are required to be kept under 9VAC25-31-840 O to ensure compliance with pretreatment standards. Such authority shall be at least as extensive as the authority provided under § 308 of the CWA.
f. Obtain remedies for noncompliance by any industrial user with any pretreatment standard and requirement. All POTWs shall be able to seek injunctive relief for noncompliance by industrial users with pretreatment standards and requirements. All POTWs shall also have authority to seek or assess civil or criminal penalties in at least the amount of $1,000 a day for each violation by industrial users of pretreatment standards and requirements.
Pretreatment requirements which will be enforced through the remedies set forth in this subdivision, will include but not be limited to, the duty to allow or carry out inspections, entry, or monitoring activities; any rules, regulations, or orders issued by the POTW; any requirements set forth in individual control mechanisms issued by the POTW; or any reporting requirements imposed by the POTW or this part. The POTW shall have authority and procedures (after informal notice to the discharger) to immediately and effectively halt or prevent any discharge of pollutants to the POTW which reasonably appears to present an imminent endangerment to the health or welfare of persons. The POTW shall also have authority and procedures (which shall include notice to the affected industrial users and an opportunity to respond) to halt or prevent any discharge to the POTW which presents or may present an endangerment to the environment or which threatens to interfere with the operation of the POTW. The director shall have authority to seek judicial relief and may also use administrative penalty authority when the POTW has sought a monetary penalty which the director believes to be insufficient.
g. Comply with the confidentiality requirements set forth in 9VAC25-31-860.
2. Procedures. The POTW shall develop and implement procedures to ensure compliance with the requirements of a pretreatment program. At a minimum, these procedures shall enable the POTW to:
a. Identify and locate all possible industrial users which might be subject to the POTW pretreatment program. Any compilation, index or inventory of industrial users made under this subdivision shall be made available to the regional administrator or department upon request.
b. Identify the character and volume of pollutants contributed to the POTW by the industrial users identified under subdivision 2 a of this subsection. This information shall be made available to the regional administrator or department upon request.
c. Notify industrial users identified under subdivision 2 a of this subsection, of applicable pretreatment standards and any applicable requirements under §§ 204(b) and 405 of the CWA and subtitles C and D of the Resource Conservation and Recovery Act (42 USC § 6901 et seq.). Within 30 days of approval pursuant to 9VAC25-31-800 F 6, of a list of significant industrial users, notify each significant industrial user of its status as such and of all requirements applicable to it as a result of such status.
d. Receive and analyze self-monitoring reports and other notices submitted by industrial users in accordance with the self-monitoring requirements in 9VAC25-31-840.
e. Randomly sample and analyze the effluent from industrial users and conduct surveillance activities in order to identify, independent of information supplied by industrial users, occasional and continuing noncompliance with pretreatment standards. Inspect and sample the effluent from each significant industrial user at least once a year except as otherwise specified below.
(1) Where the POTW has authorized the industrial user subject to a categorical pretreatment standard to forego sampling of a pollutant regulated by a categorical pretreatment standard in accordance with 9VAC25-31-840 E the POTW must sample for the waived pollutant(s) at least once during the term of the categorical industrial user's control mechanism. In the event that the POTW subsequently determines that a waived pollutant is present or is expected to be present in the industrial user's wastewater based on changes that occur in the user's operations, the POTW must immediately begin at least annual effluent monitoring of the user's discharge and inspection.
(2) Where the POTW has determined that an industrial user meets the criteria for classification as a nonsignificant categorical industrial user, the POTW must evaluate, at least once per year, whether an industrial user continues to meet the criteria in 9VAC25-31-10.
(3) In the case of industrial users subject to reduced reporting requirements under 9VAC25-31-840 E, the POTW must randomly sample and analyze the effluent from industrial users and conduct inspections at least once every two years. If the industrial user no longer meets the conditions for reduced reporting in 9VAC25-31-840 E, the POTW must immediately begin sampling and inspecting the industrial user at least once a year.
f. Evaluate whether each such significant industrial user needs a plan or other action to control slug discharges. For industrial users identified as significant prior to November 14, 2005, this evaluation must have been conducted at least once by October 14, 2005; additional significant industrial users must be evaluated within one year of being designated a significant industrial user. For purposes of this subsection, a slug discharge is any discharge of a nonroutine, episodic nature, including but not limited to an accidental spill or noncustomary batch discharge that has a reasonable potential to cause interference or pass through, or in any other way violate the POTWs regulating local limits or permit conditions. The results of such activities shall be available to the department upon request. Significant industrial users are required to notify the POTW immediately of any changes at its facility affecting potential for a slug discharge. If the POTW decides that a slug control plan is needed, the plan shall contain, at a minimum, the following elements:
(1) Description of discharge practices, including nonroutine batch discharges;
(2) Description of stored chemicals;
(3) Procedures for immediately notifying the POTW of slug discharges, including any discharge that would violate a prohibition under 9VAC25-31-770 B, with procedures for follow-up written notification within five days; and
(4) If necessary, procedures to prevent adverse impact from accidental spills, including inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site run-off, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants (including solvents), and measures and equipment necessary for emergency response.
g. Investigate instances of noncompliance with pretreatment standards and requirements, as indicated in the reports and notices required under 9VAC25-31-840, or indicated by analysis, inspection, and surveillance activities described in subdivision 2 e of this subsection. Sample taking and analysis and the collection of other information shall be performed with sufficient care to produce evidence admissible in enforcement proceedings or in judicial actions.
h. Comply with the public participation requirements of the Code of Virginia and 40 CFR Part 25
(2005)in the enforcement of national pretreatment standards. These procedures shall include provisions for at least annual public notification, in a newspaper of general circulation that provides meaningful public notice within the jurisdiction(s) served by the POTW of industrial users which, at any time during the previous 12 months were in significant noncompliance with applicable pretreatment requirements. For the purposes of this provision, a significant industrial user (or any industrial user that violates subdivision 2 h (3), (4) or (8) of this subsection is in significant noncompliance if its violation meets one or more of the following criteria:(1) Chronic violations of wastewater discharge limits, defined here as those in which 66% or more of all of the measurements taken during a six-month period exceed (by any magnitude) a numeric pretreatment standard or requirement, including instantaneous limits, as defined by 9VAC25-31-10;
(2) Technical Review Criteria (TRC) violations, defined here as those in which 33% or more of all of the measurements for each pollutant parameter taken during a six-month period equal or exceed the product of the numeric pretreatment standard or requirement, including instantaneous limits, as defined by 9VAC25-31-10; multiplied by the applicable TRC (TRC = 1.4 for BOD, TSS, fats, oil, and grease, and 1.2 for all other pollutants except pH);
(3) Any other violation of a pretreatment standard or requirement as defined by 9VAC25-31-10 (daily maximum, long-term average, instantaneous limit, or narrative standard) that the control authority POTW determines has caused, alone or in combination with other discharges, interference or pass through (including endangering the health of POTW personnel or the general public);
(4) Any discharge of a pollutant that has caused imminent endangerment to human health, welfare or to the environment or has resulted in the POTW's exercise of its emergency authority under subdivision 1 f of this subsection to halt or prevent such a discharge;
(5) Failure to meet, within 90 days after the schedule date, a compliance schedule milestone contained in a local control mechanism or enforcement order for starting construction, completing construction, or attaining final compliance;
(6) Failure to provide, within 45 days after the due date, required reports such as baseline monitoring reports, 90-day compliance reports, periodic self-monitoring reports, and reports on compliance with compliance schedules;
(7) Failure to accurately report noncompliance; or
(8) Any other violation or group of violations that may include a violation of Best Management Practices which the POTW determines will adversely affect the operation or implementation of the local pretreatment program.
3. Funding. The POTW shall have sufficient resources and qualified personnel to carry out the authorities and procedures described in subdivisions 1 and 2 of this subsection. In some limited circumstances, funding and personnel may be delayed where (i) the POTW has adequate legal authority and procedures to carry out the pretreatment program requirements described in this section, and (ii) a limited aspect of the program does not need to be implemented immediately (see 9VAC25-31-810 B).
4. Local limits. The POTW shall develop local limits as required in 9VAC25-31-770 C 1, using current influent, effluent and sludge data, or demonstrate that they are not necessary.
5. The POTW shall develop and implement an enforcement response plan. This plan shall contain detailed procedures indicating how a POTW will investigate and respond to instances of industrial user noncompliance. The plan shall, at a minimum:
a. Describe how the POTW will investigate instances of noncompliance;
b. Describe the types of escalating enforcement responses the POTW will take in response to all anticipated types of industrial user violations and the time periods within which responses will take place;
c. Identify (by title) the official or officials responsible for each type of response; and
d. Adequately reflect the POTW's primary responsibility to enforce all applicable pretreatment requirements and standards, as detailed in subdivisions 1 and 2 of this subsection.
6. The POTW shall prepare and maintain a list of its significant industrial users. The list shall identify the criteria in the definition of significant industrial user in Part I (9VAC25-31-10 et seq.) of this chapter which are applicable to each industrial user and, where applicable, shall also indicate whether the POTW has made a determination pursuant to subdivision 3 of that definition that such industrial user should not be considered a significant industrial user. This list shall be submitted to the department pursuant to 9VAC25-31-810 as a nonsubstantial program modification pursuant to 9VAC25-31-900 D. Modifications to the list shall be submitted to the department pursuant to 9VAC25-31-840 I 1.
G. A POTW that chooses to receive electronic documents must satisfy the requirements of 40 CFR Part 3 (electronic reporting).
9VAC25-31-810. POTW pretreatment programs and/or authorization to revise pretreatment standards: submission for approval.
A. A POTW requesting approval of a POTW pretreatment program shall develop a program description which includes the information set forth in subdivisions B 1 through B 4 of this section. This description shall be submitted to the department which will make a determination on the request for program approval in accordance with the procedures described in 9VAC25-31-830.
B. The program description must contain the following information:
1. A statement from the city solicitor or a city official acting in a comparable capacity (or the attorney for those POTWs which have independent legal counsel) that the POTW has authority adequate to carry out the programs described in 9VAC25-31-800. This statement shall:
a. Identify the provision of the legal authority under 9VAC25-31-800 F 1 which provides the basis for each procedure under 9VAC25-31-800 F 2;
b. Identify the manner in which the POTW will implement the program requirements set forth in 9VAC25-31-800, including the means by which pretreatment standards will be applied to individual industrial users (e.g., by order, permit, ordinance, etc.); and
c. Identify how the POTW intends to ensure compliance with pretreatment standards and requirements, and to enforce them in the event of noncompliance by industrial users;
2. A copy of any statutes, ordinances, regulations, agreements, or other authorities relied upon by the POTW for its administration of the program which meet the requirements of 9VAC25-31-800 F 1. This submission shall include a statement reflecting the endorsement or approval of the local boards or bodies responsible for supervising or funding the POTW pretreatment program if approved;
3. A brief description (including organization charts) of the POTW organization which will administer the pretreatment program. If more than one agency is responsible for administration of the program the responsible agencies shall be identified, their respective responsibilities delineated, and their procedures for coordination set forth in an inter-jurisdictional agreement; and
4. A description of the funding levels and full and part-time manpower available to implement the program.
C. The POTW may request conditional approval of the pretreatment program pending the acquisition of funding and personnel from certain elements of the program. The request for conditional approval must meet the requirements set forth in subsection B of this section except that the requirements of subsection B of this section may be relaxed if the submission demonstrates that:
1. A limited aspect of the program does not need to be implemented immediately;
2. The POTW had adequate legal authority and procedures to carry out those aspects of the program which will not be implemented immediately; and
3. Funding and personnel for the program aspects to be implemented at a later date will be available when needed. The POTW will describe in the submission the mechanism by which this funding will be acquired. Upon receipt of a request for conditional approval, the director will establish a fixed date for the acquisition of the needed funding and personnel. If funding is not acquired by this date, the conditional approval of the POTW pretreatment program and any removal allowances granted to the POTW may be modified or withdrawn.
D. The request for authority to revise categorical pretreatment standards must contain the information required in 9VAC25-31-790 D.
E. Any POTW requesting POTW pretreatment program approval shall submit to the department three copies of the submission described in subsection B, and if appropriate, subsection D of this section. Within 60 days after receiving the submission, the director shall make a preliminary determination of whether the submission meets the requirements of subsection B and, if appropriate, subsection D of this section. If the director makes the preliminary determination that the submission meets these requirements, the director shall:
1. Notify the POTW that the submission has been received and is under review; and
2. Commence the public notice and evaluation activities set forth in 9VAC25-31-830.
F. If, after review of the submission as provided for in subsection E of this section, the director determines that the submission does not comply with the requirements of subsections B or C of this section, and, if appropriate, subsection D, of this section, the director shall provide notice in writing to the applying POTW and each person who has requested individual notice. This notification shall identify any defects in the submission and advise the POTW and each person who has requested individual notice of the means by which the POTW can comply with the applicable requirements of subsections B, C of this section, and, if appropriate, subsection D of this section.
G. Consistency with water quality management plans.
1. In order to be approved the POTW pretreatment program shall be consistent with any approved water quality management plan developed in accordance with 40 CFR Parts 130
,and 131(2000), as revised, where such 208 plan includes management agency designations and addresses pretreatment in a manner consistent with this part. In order to assure such consistency the director shall solicit the review and comment of the appropriate 208 planning agency during the public comment period provided for in 9VAC25-31-830 B 1 b prior to approval or disapproval of the program.2. Where no 208 plan has been approved or where a plan has been approved but lacks management agency designations or does not address pretreatment in a manner consistent with this part, the director shall nevertheless solicit the review and comment of the appropriate 208 planning agency.
9VAC25-31-840. Reporting requirements for POTWs and industrial users.
A. (Reserved.)
B. Reporting requirements for industrial users upon effective date of categorical pretreatment standard baseline report. Within 180 days after the effective date of a categorical pretreatment standard, or 180 days after the final administrative decision made upon a category determination submission under 9VAC25-31-780 A 4, whichever is later, existing industrial users subject to such categorical pretreatment standards and currently discharging to or scheduled to discharge to a POTW shall be required to submit to the control authority a report which contains the information listed in subdivisions 1 through 7 of this subsection. At least 90 days prior to commencement of discharge, new sources and sources that become industrial users subsequent to the promulgation of an applicable categorical standard shall be required to submit to the control authority a report which contains the information listed in subdivisions 1 through 5 of this subsection. New sources shall also be required to include in this report information on the method of pretreatment the source intends to use to meet applicable pretreatment standards. New sources shall give estimates of the information requested in subdivisions 4 and 5 of this subsection.
1. Identifying information. The user shall submit the name and address of the facility including the name of the operator and owners.
2. Permits. The user shall submit a list of any environmental control permits held by or for the facility.
3. Description of operations. The user shall submit a brief description of the nature, average rate of production, and standard industrial classification of the operation or operations carried out by such industrial user. This description should include a schematic process diagram which indicates points of discharge to the POTW from the regulated processes.
4. Flow measurement. The user shall submit information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from each of the following:
a. Regulated process streams; and
b. Other streams as necessary to allow use of the combined wastestream formula of 9VAC25-31-780 E. (See subdivision 5 d of this subsection.)
The control authority may allow for verifiable estimates of these flows where justified by cost or feasibility considerations.
5. Measurement of pollutants.
a. The user shall identify the pretreatment standards applicable to each regulated process;
b. In addition, the user shall submit the results of sampling and analysis identifying the nature and concentration (or mass, where required by the standard or control authority) of regulated pollutants in the discharge from each regulated process. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations. In cases where the standard requires compliance with a Best Management Practice or pollution prevention alternative, the user shall submit documentation as required by the control authority or the applicable standards to determine compliance with the standard;
c. The user shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this subsection;
d. Samples shall be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated process if no pretreatment exists. If other wastewaters are mixed with the regulated wastewater prior to pretreatment, the user shall measure the flows and concentrations necessary to allow use of the combined wastestream formula of 9VAC25-31-780 E in order to evaluate compliance with the pretreatment standards. Where an alternate concentration or mass limit has been calculated in accordance with 9VAC25-31-780 E, this adjusted limit along with supporting data shall be submitted to the control authority;
e. Sampling and analysis shall be performed in accordance with the techniques prescribed in 40 CFR Part 136
(2005)and amendments thereto. Where 40 CFR Part 136(2005)does not contain sampling or analytical techniques for the pollutant in question, or where the administrator determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analysis shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the POTW or other parties, approved by the administrator;f. The control authority may allow the submission of a baseline report which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures; and
g. The baseline report shall indicate the time, date and place of sampling, and methods of analysis, and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to the POTW
6. Certification. A statement, reviewed by an authorized representative of the industrial user (as defined in subsection M of this section) and certified to by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance (O and M) or additional pretreatment, or both, are required for the industrial user to meet the pretreatment standards and requirements.
7. Compliance schedule. If additional pretreatment or O and M, or both, will be required to meet the pretreatment standards, the shortest schedule by which the industrial user will provide such additional pretreatment or O and M, or both. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard.
a. Where the industrial user's categorical pretreatment standard has been modified by a removal allowance (9VAC25-31-790), the combined wastestream formula (9VAC25-31-780 E), or a fundamentally different factors variance (9VAC25-31-850), or any combination of them, at the time the user submits the report required by this subsection, the information required by subdivisions 6 and 7 of this subsection shall pertain to the modified limits.
b. If the categorical pretreatment standard is modified by a removal allowance (9VAC25-31-790), the combined wastestream formula (9VAC25-31-780 E), or a fundamentally different factors variance (9VAC25-31-850), or any combination of them, after the user submits the report required by this subsection, any necessary amendments to the information requested by subdivisions 6 and 7 of this subsection shall be submitted by the user to the control authority within 60 days after the modified limit is approved.
C. Compliance schedule for meeting categorical pretreatment standards. The following conditions shall apply to the schedule required by subdivision B 7 of this section:
1. The schedule shall contain increments of progress in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the industrial user to meet the applicable categorical pretreatment standards (e.g., hiring an engineer, completing preliminary plans, completing final plans, executing contract for major components, commencing construction, completing construction, etc.);
2. No increment referred to in subdivision 1 of this subsection shall exceed nine months; and
3. Not later than 14 days following each date in the schedule and the final date for compliance, the industrial user shall submit a progress report to the control authority including, at a minimum, whether or not it complied with the increment of progress to be met on such date and, if not, the date on which it expects to comply with this increment of progress, the reason for delay, and the steps being taken by the industrial user to return the construction to the schedule established. In no event shall more than nine months elapse between such progress reports to the control authority.
D. Report on compliance with categorical pretreatment standard deadline. Within 90 days following the date for final compliance with applicable categorical pretreatment standards or in the case of a new source following commencement of the introduction of wastewater into the POTW, any industrial user subject to pretreatment standards and requirements shall submit to the control authority a report containing the information described in subdivisions B 4 through B 6 of this section. For industrial users subject to equivalent mass or concentration limits established by the control authority in accordance with the procedures in 9VAC25-31-780 C, this report shall contain a reasonable measure of the user's long-term production rate. For all other industrial users subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the user's actual production during the appropriate sampling period.
E. Periodic reports on continued compliance.
1. Any industrial user subject to a categorical pretreatment standard, after the compliance date of such pretreatment standard, or, in the case of a new source, after commencement of the discharge into the POTW, shall submit to the control authority during the months of June and December, unless required more frequently in the pretreatment standard or by the control authority or the director, a report indicating the nature and concentration of pollutants in the effluent which are limited by such categorical pretreatment standards. In addition, this report shall include a record of measured or estimated average and maximum daily flows for the reporting period for the discharge reported in subdivision B 4 of this section except that the control authority may require more detailed reporting of flows. In cases where the pretreatment standard requires compliance with a Best Management Practice (or pollution prevention alternative), the user shall submit documentation required by the control authority or the pretreatment standard necessary to determine the compliance status of the user. At the discretion of the control authority and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the control authority may agree to alter the months during which the above reports are to be submitted.
2. The control authority may authorize the industrial user subject to a categorical pretreatment standard to forego sampling of a pollutant regulated by a categorical pretreatment standard if the industrial user has demonstrated through sampling and other technical factors that the pollutant is neither present nor expected to be present in the discharge, or is present only at background levels from intake water and without any increase in the pollutant due to activities of the industrial user. This authorization is subject to the following conditions:
a. The control authority may authorize a waiver where a pollutant is determined to be present solely due to sanitary wastewater discharged from the facility provided that the sanitary wastewater is not regulated by an applicable categorical standard and otherwise includes no process wastewater.
b. The monitoring waiver is valid only for the duration of the effective period of the permit or other equivalent individual control mechanism, but in no case longer than five years. The user must submit a new request for the waiver before the waiver can be granted for each subsequent control mechanism.
c. In making a demonstration that a pollutant is not present, the industrial user must provide data from at least one sampling of the facility's process wastewater prior to any treatment present at the facility that is representative of all wastewater from all processes. The request for a monitoring waiver must be signed in accordance with subsection L of this subsection, and include the certification statement in 9VAC25-31-780 A 2 b. Nondetectable sample results may only be used as a demonstration that a pollutant is not present if the EPA approved method from 40 CFR Part 136 with the lowest minimum detection level for that pollutant was used in the analysis.
d. Any grant of the monitoring waiver by the control authority must be included as a condition in the user's control mechanism. The reasons supporting the waiver and any information submitted by the user in its request for the waiver must be maintained by the control authority for three years after expiration of the waiver.
e. Upon approval of the monitoring waiver and revision of the user's control mechanism by the control authority, the industrial user must certify on each report with the statement below, that there has been no increase in the pollutant in its wastestream due to activities of the industrial user:
"Based on my inquiry of the person or persons directly responsible for managing compliance with the pretreatment standard for 40 CFR [specify applicable national pretreatment standard part(s)], I certify that, to the best of my knowledge and belief, there has been no increase in the level of [list pollutant(s)] in the wastewaters due to the activities at the facility since filing of the last periodic report under 9VAC25-31-840 E 1."
f. In the event that a waived pollutant is found to be present or is expected to be present based on changes that occur in the user's operations, the user must immediately: Comply with the monitoring requirements of subdivision 1 of this subsection or other more frequent monitoring requirements imposed by the control authority, and notify the control authority.
g. This provision does not supersede certification processes and requirements established in categorical pretreatment standards, except as otherwise specified in the categorical pretreatment standard.
3. The control authority may reduce the requirement in the subdivision 1 of this subsection to a requirement to report no less frequently than once a year, unless required more frequently in the pretreatment standard or by the approval authority, where the industrial user meets all of the following conditions:
a. The industrial user's total categorical wastewater flow does not exceed any of the following:
(1) 0.01% of the design dry weather hydraulic capacity of the POTW, or 5,000 gallons per day, whichever is smaller, as measured by a continuous effluent flow monitoring device unless the industrial user discharges in batches;
(2) 0.01% of the design dry weather organic treatment capacity of the POTW; and
(3) 0.01% of the maximum allowable headworks loading for any pollutant regulated by the applicable categorical pretreatment standard for which approved local limits were developed by a POTW in accordance with 9VAC25-31-770 C and D.
b. The industrial user has not been in significant noncompliance, as defined in 9VAC25-31-800 F 2 g, for any time in the past two years;
c. The Industrial User does not have daily flow rates, production levels, or pollutant levels that vary so significantly that decreasing the reporting requirement for this Industrial User would result in data that are not representative of conditions occurring during the reporting period pursuant to subdivision G 3 of this section;
d. The industrial user must notify the control authority immediately of any changes at its facility causing it to no longer meet conditions of subdivision 3 a or b of this subsection. Upon notification, the industrial user must immediately begin complying with the minimum reporting in subdivision 1 of this subsection; and
e. The control authority must retain documentation to support the control authority's determination that a specific industrial user qualifies for reduced reporting requirements under subdivision 3 of this subsection for a period of three years after the expiration of the term of the control mechanism.
4. Where the control authority has imposed mass limitations on industrial users as provided for by 9VAC25-31-780 C, the report required by subdivision 1 of this subsection shall indicate the mass of pollutants regulated by pretreatment standards in the discharge from the industrial user.
5. For industrial users subject to equivalent mass or concentration limits established by the control authority in accordance with the procedures in 9VAC25-31-780 C, the report required by subdivision 1 of this subsection shall contain a reasonable measure of the user's long-term production rate. For all other industrial users subject to categorical pretreatment standards expressed only in terms of allowable pollutant discharge per unit of production (or other measure of operation), the report required by subdivision 1 of this subsection shall include the user's actual average production rate for the reporting period.
F. Notice of potential problems, including slug loading. All categorical and noncategorical industrial users shall notify the POTW immediately of all discharges that could cause problems to the POTW, including any slug loadings, as defined by 9VAC25-31-770 B, by the industrial user.
G. Monitoring and analysis to demonstrate continued compliance with pretreatment standards and requirements.
1. Except in the case of nonsignificant categorical users, the reports required in subsections B, D, E, and H of this section shall contain the results of sampling and analysis of the discharge, including the flow and the nature and concentration, or production and mass where requested by the control authority, of pollutants contained therein which are limited by the applicable pretreatment standards. This sampling and analysis may be performed by the control authority in lieu of the industrial user. Where the POTW performs the required sampling and analysis in lieu of the industrial user, the user will not be required to submit the compliance certification required under subdivision B 6 and subsection D of this section. In addition, where the POTW itself collects all the information required for the report, including flow data, the industrial user will not be required to submit the report.
2. If sampling performed by an industrial user indicates a violation, the user shall notify the control authority within 24 hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the control authority within 30 days after becoming aware of the violation. Where the control authority has performed the sampling and analysis in lieu of the industrial user, the control authority must perform the repeat sampling and analysis unless it notifies the user of the violation and requires the user to perform the repeat analysis. Resampling is not required if:
a. The control authority performs sampling at the industrial user at a frequency of at least once per month; or
b. The control authority performs sampling at the user between the time when the initial sampling was conducted and the time when the user or the control authority receives the results of this sampling.
3. The reports required in subsection E of this section must be based upon data obtained through appropriate sampling and analysis performed during the period covered by the report, which data are representative of conditions occurring during the reporting period. The control authority shall require that frequency of monitoring necessary to assess and assure compliance by industrial users with applicable pretreatment standards and requirements. Grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds. For all other pollutants, 24-hour composite samples must be obtained through flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by the control authority. Where time-proportional composite sampling or grab sampling is authorized by the control authority, the samples must be representative of the discharge and the decision to allow the alternative sampling must be documented in the industrial user file for that facility or facilities. Using protocols (including appropriate preservation) specified in 40 CFR Part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited prior to the analysis as follows: for cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil and grease the samples may be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the control authority, as appropriate.
4. For sampling required in support of baseline monitoring and 90-day compliance reports required in subsections B and D of this section, a minimum of four grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide and volatile organic compounds for facilities for which historical sampling data do not exist; for facilities for which historical sampling data are available, the Control Authority may authorize a lower minimum. For the reports required by subsections E and H of this section, the control authority shall require the number of grab samples necessary to assess and assure compliance by industrial users with applicable pretreatment standards and requirements.
5. All analyses shall be performed in accordance with procedures contained in 40 CFR Part 136
(2005)and amendments thereto or with any other test procedures approved by EPA, and shall be reported to the control authority. Sampling shall be performed in accordance with EPA-approved techniques. Where 40 CFR Part 136(2005)does not include sampling or analytical techniques for the pollutants in question, or where EPA determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed using validated analytical methods or any other sampling and analytical procedures, including procedures suggested by the POTW or other parties, approved by EPA.6. If an industrial user subject to the reporting requirement in subsection E or H of this section monitors any regulated pollutant at the appropriate sampling location more frequently than required by the control authority, using the procedures prescribed in subdivision 5 of this subsection, the results of this monitoring shall be included in the report.
H. Reporting requirements for industrial users not subject to categorical pretreatment standards. The control authority must require appropriate reporting from those industrial users with discharges that are not subject to categorical pretreatment standards. Significant noncategorical industrial users must submit to the control authority at least once every six months (on dates specified by the control authority) a description of the nature, concentration, and flow of the pollutants required to be reported by the control authority. In cases where a local limit requires compliance with a Best Management Practice or pollution prevention alternative, the user must submit documentation required by the control authority to determine the compliance status of the user. These reports must be based on sampling and analysis performed in the period covered by the report, and in accordance with the techniques described in 40 CFR Part 136
(2005)and amendments thereto. This sampling and analysis may be performed by the control authority in lieu of the significant noncategorical industrial user.I. Annual POTW reports. POTWs with approved pretreatment programs shall provide the department with a report that briefly describes the POTW's program activities, including activities of all participating agencies if more than one jurisdiction is involved in the local program. The report required by this section shall be submitted no later than one year after approval of the POTW's pretreatment program, and at least annually thereafter, and shall include, at a minimum, the following:
1. An updated list of the POTW's industrial users, including their names and addresses, or a list of deletions and additions keyed to a previously submitted list. The POTW shall provide a brief explanation of each deletion. This list shall identify which industrial users are subject to categorical pretreatment standards and specify which standards are applicable to each industrial user. The list shall indicate which industrial users are subject to local standards that are more stringent than the categorical pretreatment standards. The POTW shall also list the industrial users that are subject only to local requirements. The list must also identify industrial users subject to categorical pretreatment standards that are subject to reduced reporting requirements under subdivision E 3 of this section and identify which industrial users are nonsignificant categorical industrial users.
2. A summary of the status of industrial user compliance over the reporting period;
3. A summary of compliance and enforcement activities (including inspections) conducted by the POTW during the reporting period;
4. A summary of changes to the POTW's pretreatment program that have not been previously reported to the department; and
5. Any other relevant information requested by the director.
J. Notification of changed discharge. All industrial users shall promptly notify the control authority (and the POTW if the POTW is not the control authority) in advance of any substantial change in the volume or character of pollutants in their discharge, including the listed or characteristic hazardous wastes for which the industrial user has submitted initial notification under the Code of Virginia and this section.
K. Compliance schedule for POTWs. The following conditions and reporting requirements shall apply to the compliance schedule for development of an approvable POTW pretreatment program required by 9VAC25-31-800:
1. The schedule shall contain increments of progress in the form of dates for the commencement and completion of major events leading to the development and implementation of a POTW pretreatment program (e.g., acquiring required authorities, developing funding mechanisms, acquiring equipment);
2. No increment referred to in subdivision 1 of this subsection shall exceed nine months; and
3. Not later than 14 days following each date in the schedule and the final date for compliance, the POTW shall submit a progress report to the department including, at a minimum, whether or not it complied with the increment of progress to be met on such date and, if not, the date on which it expects to comply with this increment of progress, the reason for delay, and the steps taken by the POTW to return to the schedule established. In no event shall more than nine months elapse between such progress reports to the department.
L. Signatory requirements for industrial user reports. The reports required by subsections B, D, and E of this section shall include the certification statement as set forth in 9VAC25-31-780 A 2 b, and shall be signed as follows:
1. By a responsible corporate officer, if the industrial user submitting the reports required by subsections B, D and E of this section is a corporation. For the purpose of this subdivision, a responsible corporate officer means (i) a president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy-making or decision-making functions for the corporation, or (ii) the manager of one or more manufacturing, production, or operating facilities, provided, the manager is authorized to make management decisions that govern the operation of the regulated facility including having the explicit or implicit duty of making major capital investment recommendations, and initiate and direct other comprehensive measures to assure long-term environmental compliance with environmental laws and regulations; can ensure that the necessary systems are established or actions taken to gather complete and accurate information for control mechanism requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures.
2. By a general partner or proprietor if the industrial user submitting the reports required by subsections B, D and E of this section is a partnership or sole proprietorship, respectively.

b. The authorization specifies either an individual or a position having responsibility for the overall operation of the facility from which the industrial discharge originates, such as the position of plant manager, operator of a well, or well field superintendent, or a position of equivalent responsibility, or having overall responsibility for environmental matters for the company; and
c. The written authorization is submitted to the control authority.
4. If an authorization under subdivision 3 of this subsection is no longer accurate because a different individual or position has responsibility for the overall operation of the facility, or overall responsibility for environmental matters for the company, a new authorization satisfying the requirements of subdivision 3 of this subsection must be submitted to the control authority prior to or together with any reports to be signed by an authorized representative.
M. Signatory requirements for POTW reports. Reports submitted to the department by the POTW in accordance with subsection I of this section must be signed by a principal executive officer, ranking elected official or other duly authorized employee The duly authorized employee must be an individual or position having responsibility for the overall operation of the facility or the pretreatment program. This authorization must be made in writing by the principal executive officer or ranking elected official, and submitted to the approval authority prior to or together with the report being submitted.
N. Provision governing fraud and false statements. The reports and other documents required to be submitted or maintained under this section shall be subject to:
1. The provisions of 18 USC § 1001 relating to fraud and false statements;
2. The provisions of the law or § 309(c)(4) of the CWA, as amended, governing false statements, representation or certification; and
3. The provisions of § 309(c)(6) of the CWA regarding responsible corporate officers.
O. Recordkeeping requirements.
1. Any industrial user and POTW subject to the reporting requirements established in this section shall maintain records of all information resulting from any monitoring activities required by this section including documentation associated with Best Management Practices. Such records shall include for all samples:
a. The date, exact place, method, and time of sampling and the names of the person or persons taking the samples;
b. The dates analyses were performed;
c. Who performed the analyses;
d. The analytical techniques/methods used; and
e. The results of such analyses.
2. Any industrial user or POTW subject to the reporting requirements established in this section (including documentation associated with Best Management Practices) shall be required to retain for a minimum of three years any records of monitoring activities and results (whether or not such monitoring activities are required by this section) and shall make such records available for inspection and copying by the director and the regional administrator (and POTW in the case of an industrial user). This period of retention shall be extended during the course of any unresolved litigation regarding the industrial user or POTW or when requested by the director or the regional administrator.
3. Any POTW to which reports are submitted by an industrial user pursuant to subsections B, D, E, and H of this section shall retain such reports for a minimum of three years and shall make such reports available for inspection and copying by the director and the regional administrator. This period of retention shall be extended during the course of any unresolved litigation regarding the discharge of pollutants by the industrial user or the operation of the POTW pretreatment program or when requested by the director or the regional administrator.
P. 1. The industrial user shall notify the POTW, the EPA Regional Waste Management Division Director, and state hazardous waste authorities in writing of any discharge into the POTW of a substance, which, if otherwise disposed of, would be a hazardous waste under the Code of Virginia and 40 CFR Part 261
(2005). Such notification must include the name of the hazardous waste as set forth in the Code of Virginia and 40 CFR Part 261(2005), the EPA hazardous waste number, and the type of discharge (continuous, batch, or other). If the industrial user discharges more than 100 kilograms of such waste per calendar month to the POTW, the notification shall also contain the following information to the extent such information is known and readily available to the industrial user: An identification of the hazardous constituents contained in the wastes, an estimation of the mass and concentration of such constituents in the wastestream discharged during that calendar month, and an estimation of the mass of constituents in the wastestream expected to be discharged during the following 12 months. All notifications must take place within 180 days of the effective date of this rule. Industrial users who commence discharging after the effective date of this rule shall provide the notification no later than 180 days after the discharge of the listed or characteristic hazardous waste. Any notification under this subsection need be submitted only once for each hazardous waste discharged. However, notifications of changed discharges must be submitted under subsection J of this section. The notification requirement in this section does not apply to pollutants already reported under self-monitoring requirements of subsections B, D, and E of this section.2. Dischargers are exempt from the requirements of subdivision 1 of this subsection during a calendar month in which they discharge no more than 15 kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e)
(2005). Discharge of more than 15 kilograms of nonacute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e)(2005), requires a one-time notification. Subsequent months during which the industrial user discharges more than such quantities of any hazardous waste do not require additional notification.3. In the case of any new regulations under § 3001 of RCRA (42 USC § 6901 et seq.) identifying additional characteristics of hazardous waste or listing any additional substance as a hazardous waste, the industrial user must notify the POTW, the EPA Regional Waste Management Waste Division Director, and state hazardous waste authorities of the discharge of such substance within 90 days of the effective date of such regulations.
4. In the case of any notification made under this subsection, the industrial user shall certify that it has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical.
Q. Annual certification by nonsignificant categorical industrial users. A facility determined to be a nonsignificant categorical industrial user pursuant to 9VAC25-31-10 must annually submit the following certification statement, signed in accordance with the signatory requirements in subsection L of this section. This certification must accompany an alternative report required by the control authority:
"Based on my inquiry of the person or persons directly responsible for managing compliance with the categorical pretreatment standards under 40 CFR ____, I certify that, to the best of my knowledge and belief that during the period from __________, ________ to ________, ________ [months, days, year]:
1. The facility described as ____________________ [facility name] met the definition of a nonsignificant categorical industrial user as described in 9VAC25-31-10;
2. The facility complied with all applicable pretreatment standards and requirements during this reporting period; and
3. The facility never discharged more than 100 gallons of total categorical wastewater on any given day during this reporting period. This compliance certification is based upon the following information.
_____________"
R. The control authority that chooses to receive electronic documents must satisfy the requirements of 40 CFR Part 3 (Electronic reporting).
9VAC25-31-900. Modification of POTW pretreatment programs.
A. Either the director or a POTW with an approved POTW pretreatment program may initiate program modification at any time to reflect changing conditions at the POTW. Program modification is necessary whenever there is a significant change in the operation of a POTW pretreatment program that differs from the information in the POTW's submission, as approved under 9VAC25-31-830.
B. Substantial modifications defined. Substantial modifications include:
1. Modifications that relax POTW legal authorities (as described in 9VAC25-31-800 F 1, except for modifications that directly reflect a revision to this part or to 40 CFR Chapter I, Subchapter N
(2000), and are reported pursuant to subsection D of this section;2. Modifications that relax local limits, except for the modifications to local limits for pH and reallocations of the maximum allowable industrial loading of a pollutant that do not increase the total industrial loadings for the pollutant, which are reported pursuant to subsection D of this section. Maximum allowable industrial loading means the total mass of a pollutant that all industrial users of a POTW (or a subgroup of industrial users identified by the POTW) may discharge pursuant to limits developed under 9VAC25-31-770 C;
3. Changes to the POTW's control mechanism as described in 9VAC25-31-800 F 1 c;
4. A decrease in the frequency of self-monitoring or reporting required of industrial users;
5. A decrease in the frequency of industrial user inspections or sampling by the POTW;
6. Changes to the POTW's confidentiality procedures; and
7. Other modifications designated as substantial modifications by the director on the basis that the modification could have a significant impact on the operation of the POTW's pretreatment program, could result in an increase in pollutant loadings at the POTW, or could result in less stringent requirements being imposed on industrial users of the POTW.
C. Approval procedures for substantial modifications.
1. The POTW shall submit to the department a statement of the basis for the desired program modification, a modified program description (see 9VAC25-31-810 B), or such other documents the director determines to be necessary under the circumstances.
2. The director shall approve or disapprove the modification based on the requirements of 9VAC25-31-800 F and using the procedures in 9VAC25-31-830 B through F, except as provided in subdivisions C 3 and C 4 of this section. The modification shall become effective upon approval by the director.
3. The director need not publish a notice of decision under 9VAC25-31-830 E provided (i) the notice of request for approval under 9VAC25-31-830 B 1 states that the request will be approved if no comments are received by a date specified in the notice; (ii) no substantive comments are received; and (iii) the request is approved without change.
4. Notices required by 9VAC25-31-830 may be performed by the POTW provided that the director finds that the POTW notice otherwise satisfies the requirements of 9VAC25-31-830.
D. Approval procedures for nonsubstantial modifications.
1. The POTW shall notify the department of any nonsubstantial modification at least 45 days prior to implementation by the POTW in a statement similar to that provided for in subdivision C 1 of this section.
2. Within 45 days after the submission of the POTW's statement, the director shall notify the POTW of his decision to approve or disapprove the nonsubstantial modification.
3. If the director does not notify the POTW within 45 days of his decision to approve or deny the modification or to treat the modification as substantial under subdivision B 7 of this section, the POTW may implement the modification.
E. Incorporation in permit. All modifications shall be incorporated into the POTW's VPDES permit upon approval. The permit will be modified to incorporate the approved modification in accordance with 9VAC25-31-400.
