Summary:

The regulatory action reissues the existing Virginia Pollutant Discharge Elimination System (VPDES) general permit that expires on September 30, 2013. The general permit contains limitations and monitoring requirements for point source discharge of treated wastewaters from concrete products facilities to surface waters.

Substantive changes (i) add two reasons authorization to discharge cannot be granted (if the antidegradation policy is not met or if the discharge is not consistent with a total maximum daily load (TMDL)), (ii) add language to allow for administrative continuances of coverage, (iii) add approval of representative outfalls and closure plans for portable plants as part of the registration, (iv) reduce monitoring requirements from monthly to quarterly, (v) clarify that total petroleum hydrocarbon monitoring was only necessary when vehicle degreasing was occurring on site, (vi) add benchmark monitoring concentrations for storm water, and (vii) remove total petroleum hydrocarbon and iron monitoring from the storm water limits page.

In the special conditions, the changes clarify what information is required for temporary and long-term facility closure plans and add (i) that no oil sheen shall be present and waste water should be reused or recycled when feasible, (ii) that settling basins must be lined if they are expanded, (iii) quantification levels of total suspended solids and total petroleum hydrocarbons, (iv) that discharges to TMDL waters must implement measures and controls consistent with the TMDL, (v) an allowance for deleting or adding outfalls, (vi) procedures for termination of coverage, (vii) instructions for allowing temporary closures for inactive and unstaffed sites, (viii) that discharges must meet water quality standards, and (ix) that coverage under the permit did not relieve an owner of compliance with any other federal, state, or local statute, ordinance, or regulation.

This action revises Part II (Storm Water Management) to make it more consistent with the 2009 Industrial Storm Water General Permit (9VAC25-151) conditions. Changes make this general permit similar to other general permits issued recently and respond to staff and technical advisory committee members' requests to clarify and update permit limits and conditions.

The changes made to the proposed regulation are for clarification and are not substantive.

All storm water samples shall be collected from the discharge resulting from a storm event that is greater than 0.1 inches in magnitude and that occurs at least 72 hours from the previously measurable (greater than 0.1 inch rainfall) storm event. Specific storm event data shall be reported with the Discharge Monitoring Report in accordance with Part II A.

5. Reports of annual monitoring shall be submitted to the DEQ regional office no later than the 10th day of January of each year.

6. A quarterly visual monitoring shall be performed and recorded in accordance with Part II D.

⁽²⁾Should the benchmark monitoring for TSS exceed 100 mg/l maximum or the pH fall outside of the range of 6.0-9.0 standard units, the permittee shall evaluate the overall effectiveness of the SWPPP in controlling the discharge of pollutants to receiving waters. Benchmark concentration values are not effluent limitations. Exceedance of a benchmark concentration does not constitute a violation of this permit and does not indicate that violation of a water quality standard has occurred; however, it does signal that modifications to the SWPPP are necessary, unless justification is provided in the routine facility inspection or comprehensive site compliance evaluation.

⁽³⁾Specific storm event data shall be reported with the Discharge Monitoring Report (DMR) in accordance with Part II A.

⁽⁴⁾1/year means one sample taken per calendar year with the annual [ report DMR ] due to the DEQ regional office no later than the 10th day of January of each year.

Part II.
Storm Water Management.

A. Monitoring instructions.

1. Collection and analysis of samples. Sampling requirements shall be assessed on an outfall by outfall basis. Samples shall be collected and analyzed in accordance with the requirements of Part III A.

2. When and how to sample. A minimum of one grab sample shall be taken resulting from a storm event that results in an actual discharge from the site (defined as a "measureable storm event"), providing the interval from the preceding measurable storm event is at least 72 hours. The 72-hour storm interval is waived if the permittee is able to document with the discharge monitoring report (DMR) that less than a 72-hour interval is representative for local storm events during the sampling period. The grab sample shall be taken during the first 30 minutes of the discharge. If it is not practicable to take the sample during the first 30 minutes, the sample may be taken during the first hour of discharge [ provide provided ] that the permittee explains with the DMR why a grab sample during the first 30 minutes was impractical.

A. 3. Recording of results. For each discharge measurement or sample taken pursuant to the storm event monitoring requirements of this permit, the permittee shall record and report with the Discharge Monitoring Reports (DMRs) the following information:

1. The date a. Date and duration (in hours) of the storm event(s) sampled;

2. The rainfall b. Rainfall measurements or estimates (in inches) of the storm event which generated the sampled discharge; and

3. The duration c. Duration between the storm event sampled and the end of the previous measurable (greater than 0.1 inch rainfall) storm event.

B. Representative discharge. When If a facility has two or more exclusively storm water outfalls that discharge substantially identical effluents, based on a consideration of industrial activity similarities of the industrial activities, significant materials, and management practices and activities within the area drained by the outfall, the permittee reasonably believes discharge substantially identical effluent, the permittee may test the effluent of one of such outfalls and include with the DMRs an explanation that the quantitative data also applies to the substantially identical outfalls provided that the permittee includes a description of the location of the outfalls and explains in detail why the outfalls are expected to discharge substantially identical effluent. In addition, for each exclusively storm water outfall that the permittee believes is representative, an estimate of the size of the drainage area (in square feet) and an estimate of the runoff coefficient of the drainage area (e.g., low (under 40%), medium (40% to 65%) or high (above 65%)) shall be provided. size of drainage areas, and storm water management practices occurring within the drainage areas of the outfalls, the permittee may monitor the effluent of just one of the outfalls. Representative outfalls must be identified in the registration statement submitted for coverage under this permit. Substantially identical outfalls can apply to quarterly visual and benchmark monitoring. The permittee must include the following information in the storm water pollution prevention plan (SWPPP):

1. The locations of the outfalls;

2. Why the outfalls are expected to discharge substantially identical effluents;

3. Estimates of the size of the drainage area (in square feet) for each of the outfalls; and

4. An estimate of the runoff coefficient of the drainage areas (low: under 40%; medium: 40% to 65%; high: above 65%).

C. Sampling waiver waivers.

1. When a permittee is unable to collect storm water samples required in Part I A or other applicable sections of this permit within a specified sampling period conduct benchmark monitoring or visual examinations within the specified sampling period due to no "measureable" storm event or adverse climatic weather conditions, the permittee shall collect a substitute sample from a the next separate qualifying event in the next period and submit these data along with the data for the routine sample in that period documentation explaining a facility's inability to conduct benchmark monitoring or visual examinations (including dates and times the outfalls were viewed and sampling was attempted) of no "measureable" storm event or of adverse weather conditions with the DMR to the DEQ. Adverse weather conditions which may prohibit the collection of samples include weather conditions that create dangerous conditions for personnel (such as local flooding, high winds, hurricane, tornadoes, electrical storms, etc.) or otherwise make the collection of a sample impracticable (drought, extended frozen conditions, etc.). Acceptable documentation includes, but is not limited to National Climatic Data Center weather station data, local weather station data, facility rainfall logs, and other appropriate supporting data. All documentation shall also be maintained with the SWPPP.

2. Sampling waiver for inactive and unstaffed sites. See Part I B 20.

D. Quarterly visual examination of storm water quality. The permittee shall perform and document a visual examination of a storm water discharge associated with industrial activity from each outfall, except discharges exempted below waived in subdivision D 1 and subsection C of this section. The visual examination(s) must be made during daylight hours (e.g., normal working hours), at least once in each of the following three-month periods: January through March, April through June, July through September, and October through December.

1. Examinations shall be made of samples collected within the first 30 minutes (or as soon thereafter as practical, but not to exceed one hour) of when the runoff or snowmelt begins discharging. The examination shall document observations of color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of storm water pollution. The examination must be conducted in a well lit area. No analytical tests are required to be performed on the samples. All such samples shall be collected from the discharge resulting from a storm event that is greater than 0.1 inches in magnitude and that occurs at least 72 hours from the previous measurable (greater than 0.1 inch rainfall) storm event results in an actual discharge from the site (defined as a "measurable storm event") providing the interval from the preceding measurable storm event is at least 72 hours. The required 72-hour storm event interval is waived where the preceding measurable storm event did not result in a measurable discharge from the facility. The required 72-hour storm event interval may also be waived where the permittee documents that less than a 72-hour interval is representative for local storm events during the season when sampling is being conducted. If no qualifying storm event resulted in discharge from the facility during a monitoring period, visual monitoring is exempted provided that the permittee document documents that no qualifying storm event occurred that resulted in a storm water discharge during that quarter. Where practicable, the same individual should carry out the collection and examination of discharges for the entire permit term.

2. Visual examination reports must be maintained onsite with the pollution prevention plan SWPPP. The report shall include the outfall location, the examination date and time, examination personnel, the nature of the discharge (i.e., runoff or snow melt), visual quality of the storm water discharge (including observations of color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of storm water pollution), visual quality of the receiving stream (including observations of solids deposition and oil sheen from the industrial activity) in the vicinity of the outfall (including ditches and conveyances) and probable sources of any observed storm water contamination.

3. If the facility has two or more outfalls that, based on a consideration of industrial activity, significant materials, and management practices and activities within the area drained by the outfall, the permittee reasonably believes discharge substantially identical effluents, the permittee may collect a sample of effluent of one of such outfalls and report that the examination data also applies to the substantially identical outfall(s) provided that the permittee includes in the storm water pollution prevention plan a description of the location of the outfalls and explains in detail why the outfalls are expected to discharge substantially identical effluents. In addition, for each outfall that the permittee believes is representative, an estimate of the size of the drainage area (in square feet) and an estimate of the runoff coefficient of the drainage area (i.e., low (under 40%), medium (40 to 65%), or high (above 65%)) shall be provided in the plan.

4. When the permittee is unable to conduct the visual examination due to adverse climatic conditions, the permittee must document the reason for not performing the visual examination and retain this documentation onsite with the records of the visual examinations. Adverse weather conditions that may prohibit the collection of samples include weather conditions that create dangerous conditions for personnel (such as local flooding, high winds, hurricane, tornadoes, electrical storms, etc.) or otherwise make the collection of a sample impracticable (drought, extended frozen conditions, etc.).

"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."

L. Duty to comply. The permittee shall comply with all conditions of this permit. Any permit noncompliance constitutes a violation of the State Water Control Law and the Clean Water Act, except that noncompliance with certain provisions of this permit may constitute a violation of the State Water Control Law but not the Clean Water Act. 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 Clean Water Act for toxic pollutants and with standards for sewage sludge use or disposal established under § 405(d) of the Clean Water Act within the time provided in the regulations that establish these standards or prohibitions or standards for sewage sludge use or disposal, even if this permit has not yet been modified to incorporate the requirement.

M. Duty to reapply. If the permittee wishes to continue an activity regulated by this permit after the expiration date of this permit, the permittee shall apply for and obtain a new permit. All permittees with a currently effective permit shall submit a new application at least 180 90 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.

N. Effect of a permit. This permit does not convey any property rights in either real or personal property or any exclusive privileges, nor does it authorize any injury to private property or invasion of personal rights, or any infringement of federal, state or local law or regulations.

O. State law. Nothing in this permit shall be construed to preclude the institution of any legal action under, or relieve the permittee from any responsibilities, liabilities, or penalties established pursuant to any other state law or regulation or under authority preserved by § 510 of the Clean Water Act. Except as provided in permit conditions on "bypassing" (Part III U), and "upset" (Part III V) nothing in this permit shall be construed to relieve the permittee from civil and criminal penalties for noncompliance.

P. Oil and hazardous substance liability. Nothing in this permit shall be construed to preclude the institution of any legal action or relieve the permittee from any responsibilities, liabilities, or penalties to which the permittee is or may be subject under §§ 62.1-44.34:14 through 62.1-44.34:23 of the State Water Control Law.

Q. Proper operation and maintenance. 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 this permit. Proper operation and maintenance also includes effective plant performance, adequate funding, adequate staffing, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by the permittee only when the operation is necessary to achieve compliance with the conditions of this permit.

R. Disposal of solids or sludges. Solids, sludges or other pollutants removed in the course of treatment or management of pollutants shall be disposed of in a manner so as to prevent any pollutant from such materials from entering state waters.

S. Duty to mitigate. The permittee shall take all reasonable steps to minimize or prevent any discharge or sludge use or disposal in violation of this permit which has a reasonable likelihood of adversely affecting human health or the environment.

T. Need to halt or reduce activity not a defense. 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 this permit.

U. Bypass.

1. "Bypass" means the intentional diversion of waste streams from any portion of a treatment facility. 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 Parts III U 2 and U 3.

2. Notice.

a. Anticipated bypass. If the permittee knows in advance of the need for a bypass, prior notice shall be submitted, 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 Part III I.

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 Part III U 2.

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 Part III U 3 a.

V. Upset.

1. An upset constitutes an affirmative defense to an action brought for noncompliance with technology based permit effluent limitations if the requirements of Part III V 2 are met. A determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is not a 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 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 Part III I; and

d. The permittee complied with any remedial measures required under Part III S.

3. In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has the burden of proof.

W. Inspection and entry. The permittee shall allow the director, or his designee, 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 this permit;

2. Have access to and copy at reasonable times any records that must be kept under the conditions of this permit;

3. Inspect at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this permit; and

4. Sample or monitor at reasonable times, for the purposes of assuring permit compliance or as otherwise authorized by the Clean Water Act and the State Water Control Law, any substances or parameters at any location.

For purposes of this section, the time for inspection shall be deemed reasonable during regular business hours, and whenever the facility is discharging. Nothing contained herein shall make an inspection unreasonable during an emergency.

X. Permit actions. 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.

Y. Transfer of permits.

[ 1. ] Permits are not transferable to any person except after notice to the department. [ Except as provided in Part III Y 2, a permit may be transferred by the permittee to a new owner or operator only if the permit has been modified or revoked and reissued, or a minor modification made, to identify the new permittee and incorporate such other requirements as may be necessary under the State Water Control Law and the Clean Water Act.

2. As an alternative to transfers under Part III Y 1, this This ] permit may be automatically transferred to a new permittee if:

[ a. 1. ] The current permittee notifies the department at least [ within ] 30 days in advance of the proposed transfer of the title to the facility or property [ unless permission for a later date has been granted by the board ];

[ b. 2. ] The notice includes a written agreement between the existing and new permittees containing a specific date for transfer of permit responsibility, coverage, and liability between them; and

[ c. 3. ] The board does not notify the existing permittee and the proposed new permittee of its intent to [ modify or revoke and reissue deny the new permittee coverage under ] the permit. If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in [ Part III Y 2 b Part III Y 2 ].

Z. Severability. The provisions of this permit are severable, and if any provision of this permit or the application of any provision of this permit to any circumstance is held invalid, the application of such provision to other circumstances, and the remainder of this permit, shall not be affected thereby.
