Summary:

This regulation will reissue the existing general permit for industrial activity storm water discharges that will expire on June 30, 2009. This draft is generally modeled after EPA's proposed 2006 Multi-Sector General Permit. The significant revisions to the regulation are as follows:

1. Registration Statement and SWPPP. Clarified that the SWPPP must be prepared and implemented prior to the submittal of the registration statement, and that existing permittees who intend to continue coverage under this GP must review and update the SWPPP to meet any new permit requirements prior to submitting their registration statement.

2. General permit, Part I A - Effluent Limitations, Monitoring Requirements and Special Conditions.

a. Monitoring. Set the monitoring periods for benchmark monitoring, and effluent limitation monitoring (including coal pile runoff monitoring) to (1) July 1, 2009, to December 31, 2009; and (2) January 1 to December 31 for each of the remaining years of the permit term. Required DMRs to be submitted by January 30 for both benchmark monitoring and effluent limitation monitoring.

b. Added monitoring requirements for facilities subject to TMDL waste load allocations. Facilities will be given written notification from DEQ that they are subject to TMDL monitoring. Required the monitoring to be conducted at least semi-annually. Required TMDL WLA monitoring to be submitted by each July 30th and January 30th.

c. Monitoring waivers. Deleted the alternative certification of "not present" or "no exposure" to be consistent with EPA's proposed 2006 MSGP.

d. Corrective Actions. Added a section that describes actions that the permittee must take if (a) benchmark monitoring results exceed benchmark monitoring concentrations; (b) routine facility inspections, comprehensive site compliance evaluations, facility inspections, or other observations result in discovery of a deficiency; or (c) there is an exceedance of an effluent limitation, TMDL wasteload allocation or a water quality standard. For exceedances of an effluent limitation, TMDL wasteload allocation or a water quality standard, the permittee must conduct follow-up monitoring and reporting on the schedule set in the permit until the results indicate that the limitation/allocation/standard is no longer being exceeded. Required follow-up monitoring to be submitted on a DMR no later than 30 days after the results are received.

e. Special Conditions

(1) Salt storage piles. Added a requirement for all salt storage piles to be located on an impervious surface, and a requirement that all runoff from the pile, and/or runoff that comes in contact with salt, including under drain systems, be collected and contained within a basin lined with concrete or other impermeable materials, and that the lined basin be bermed and sized to contain runoff resulting from a 24-hour 25-year storm event. Salt contaminated stormwater is not allowed to be discharged directly to the ground or to state waters.

(2) Discharges to Waters Subject to TMDL WLA's. Added a special condition requiring facilities that are an identified source of the pollutant of concern to TMDL waters (board established and EPA-approved prior to the term of the permit) to incorporate measures and controls into their SWPPP to address the TMDL requirements, and any waste load allocations that impact the facility. DEQ will notify the permittee that they are subject to the TMDL requirements. If the TMDL establishes a specific WLA that applies to the facility's discharges, the permittee must address that allocation in the SWPPP, perform TMDL monitoring, and implement measures to meet the allocation.

3. General permit, Part III - Storm Water Pollution Prevention Plan.

a. Changed the deadline to update and implement any revisions to the SWPPP to "prior to submitting the registration statement."

b. Maintenance. Added a requirement that storm water BMPs be observed during active operation to ensure they are operating properly.

c. Nonstorm Water Discharges. Added a statement that all nonstorm water discharges are subject to all the provisions of this permit, including numeric effluent limitations, benchmarks and monitoring requirements.

d. Comprehensive Site Compliance Evaluation. Added the following things for facility personnel to evaluate: (i) evidence of pollutants discharging to surface waters at all facility outfalls, and the condition of and around the outfall, including flow dissipation measures to prevent scouring; (ii) review of training performed, inspections completed, maintenance performed, quarterly visual examinations, and effective operation of BMPs; and (iii) certification of outfall evaluation for unauthorized discharges (this had been in the Part III C nonstorm water discharges section). Changed this to an annual certification. Removed the provision allowing the permittee to skip the certification if they previously did a certification and believed nothing had changed at the facility. If the permittee fails to do the certification, they must notify DEQ of the reason within 14 days after completion of the annual site compliance evaluation.

e. SWPPP Modifications. Deleted the provision that allowed the permittee to use the annual site compliance evaluation to satisfy a routine facility inspection where the schedules overlapped.

4. General permit, Part IV - Sector Specific Permit Requirements.

a. Added benchmark monitoring for TSS to all sectors that had benchmark monitoring in the previous permit if they didn't already have TSS monitoring.

b. Sector A - Timber Products. Added benchmark monitoring for Phenols to "Wood Preserving Facilities" (SIC 2491).

c. Sector C - Chemical and Allied Products. Added benchmark monitoring for Zinc to "Industrial Inorganic Chemicals Facilities" (SIC 2812-2819)

d. Sector F - Primary Metals. Changed the routine facility inspection frequency from quarterly to monthly.

e. Sector G - Metal Mining. Added the following to the description of covered discharges: (1) storm water discharges from exploration and development of metal mining and/or ore dressing facilities; and (2) storm water discharges from facilities at mining sites undergoing reclamation. Added a section on "Clearing, Grading and Excavation Activities". Added a section for "Termination of permit coverage."

f. Sector I - Oil and Gas Extraction and Refining. Changed the routine facility inspection frequencies to monthly. Added benchmark monitoring for Lead, Nickel, Zinc, TKN, Total Nitrogen, and TSS to "Oil Refining Facilities" (SIC 2911).

g. Sector M - Automobile Salvage Yards. Added mercury switches to the list of things to inspect for leaks, and to train personnel on the proper handling of.

h. Sector N - Scrap Recycling and Waste Recycling Facilities. Added requirements for mercury switch removal, inspection and spill clean-up. For scrap recycling and waste recycling facilities (both types), changed the inspection frequency from quarterly to monthly.

A. Any owner governed by this general permit is hereby authorized to discharge storm water associated with industrial activity (as defined in this regulation) to surface waters of the Commonwealth of Virginia provided that the owner files the registration statement of 9VAC25-151-60, pays any fees required by 9VAC25-20, receives a copy of the general permit, and complies with the requirements of 9VAC25-151-70 et seq. and provided that:

1. Facilities with colocated industrial activities on-site shall comply with all applicable effluent limitations, monitoring and pollution prevention plan requirements of each section of 9VAC25-151-70 et seq. in which a colocated industrial activity is described;

2. Storm water discharges associated with industrial activity that are mixed with other discharges (both storm water and nonstorm water) requiring a VPDES permit are authorized by this permit, provided that the owner obtains coverage under this VPDES general permit for the industrial activity discharges, and a VPDES general or individual permit for the other discharges. The owner shall comply with the terms and requirements of each permit obtained that authorizes any component of the discharge;

3. The storm water discharges authorized by this permit may be combined with other sources of storm water which are not required to be covered under a VPDES permit, so long as the combined discharge is in compliance with this permit; and

4. Authorized nonstorm water discharges. The following nonstorm "nonstorm water" discharges are authorized by this permit, provided the nonstorm water component of the facility's discharge is in compliance with 9VAC25-151-70, Part III D 2:

a. Discharges from fire fighting activities;

b. Fire hydrant flushings;

c. Potable water including water line flushings;

d. Uncontaminated air conditioning or compressor condensate (excluding air compressors);

GENERAL PERMIT FOR STORM WATER DISCHARGES ASSOCIATED WITH INDUSTRIAL ACTIVITY

AUTHORIZATION TO DISCHARGE UNDER THE VIRGINIA POLLUTANT DISCHARGE ELIMINATION SYSTEM AND THE VIRGINIA STATE WATER CONTROL LAW

In compliance with the provisions of the Clean Water Act, as amended, and pursuant to the State Water Control Law and regulations adopted pursuant thereto, owners of facilities with storm water discharges associated with industrial activity are authorized to discharge to surface waters within the boundaries of the Commonwealth of Virginia, except those waters specifically named in board regulation or policies which prohibit such discharges.

The authorized discharge shall be in accordance with this cover page, Part I-Effluent Limitations, Monitoring Requirements and Special Conditions, Part II-Conditions Applicable to All VPDES Permits, Part III-Storm Water Pollution Prevention Plan, and Part IV-Sector-Specific Permit Requirements, as set forth herein.

Part I
Effluent Limitations, Monitoring Requirements and Special Conditions

A. Effluent limitations and monitoring requirements.

There are four three individual and separate categories of monitoring requirements and numeric effluent limitations that a facility may be subject to under this permit: (i) quarterly visual monitoring; (ii) benchmark monitoring of discharges associated with specific industrial activities; and (iii) compliance monitoring for discharges subject to numerical effluent limitations. The monitoring requirements and numeric effluent limitations applicable to a facility depend on the types of industrial activities generating storm water runoff from the facility, and for TMDL monitoring, the location of the facility. Part IV of the permit (9VAC25-151-90 et seq.) identifies monitoring requirements applicable to specific sectors of industrial activity. The permittee must shall review Part I A 1 and Part IV of the permit to determine which monitoring requirements and numeric limitations apply to his facility. Unless otherwise specified, limitations and monitoring requirements under Part I A 1 and Part IV are additive.

Sector-specific monitoring requirements and limitations are applied discharge by discharge at facilities with colocated activities. Where storm water from the colocated activities are commingled, the monitoring requirements and limitations are additive. Where more than one numeric limitation for a specific parameter applies to a discharge, compliance with the more restrictive limitation is required. Where monitoring requirements for a monitoring period overlap (e.g., need to monitor TSS one/year for a limit and also one/year for benchmark monitoring), the permittee may use a single sample to satisfy both monitoring requirements.

1. Types of monitoring requirements and limitations.

a. Quarterly visual monitoring. The requirements and procedures for quarterly visual monitoring are applicable to all facilities covered under this permit, regardless of the facility's sector of industrial activity.

(1) The permittee must shall perform and document a quarterly visual examination of a storm water discharge associated with industrial activity from each outfall, except discharges exempted below (Part I A 1 a (2) and (4), and Part I A 3). Unless another schedule is established in applicable sectors of Part IV (sections of 9VAC25-151-90 et seq.), the examination(s) must The examination(s) shall be made at least once in each of the following three-month periods: January through March, April through June, July through September, and October through December. The visual examination must shall be made during daylight hours (e.g., normal working hours). If no storm event resulted in runoff from the facility during a monitoring quarter, the permittee is excused from visual monitoring for that quarter provided that documentation is included with the monitoring records indicating that no runoff occurred. The documentation must shall be signed and certified in accordance with Part II K of this permit.

(2) Visual examinations must 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 from the facility. The examination must 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 shall be conducted in a well-lit area. No analytical tests are required to be performed on the samples. All samples (except snowmelt samples) must 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. The 72-hour storm interval is waived when the preceding measurable storm did not yield a measurable discharge, or if the permittee is able to document that less than a 72-hour interval is representative for local storm events during the sampling period. Where practicable, the same individual should shall carry out the collection and examination of discharges for the entire permit term. If no qualifying storm event resulted in runoff during daylight hours from the facility during a monitoring quarter, the permittee is excused from visual monitoring for that quarter provided that documentation is included with the monitoring records indicating that no qualifying storm event occurred during daylight hours that resulted in storm water runoff during that quarter. The documentation must shall be signed and certified in accordance with Part II K.

(3) The visual examination reports must shall be maintained on-site with the Storm Water Pollution Prevention Plan (SWPPP). The report must 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), and probable sources of any observed storm water contamination.

(4) Inactive and unstaffed sites: When the permittee is unable to conduct visual storm water examinations at an inactive and unstaffed site, a waiver of the monitoring requirement may be exercised as long as the facility remains inactive and unstaffed, and there are no industrial materials or activities exposed to storm water. If this waiver is exercised, the permittee must shall maintain a certification with the SWPPP stating that the site is inactive and unstaffed, there are no industrial materials or activities exposed to storm water, and that performing visual examinations during a qualifying event is not feasible. The waiver must shall be signed and certified in accordance with Part II K.

(5) Representative outfalls - essentially identical discharges. If the facility has two or more outfalls that discharge substantially identical effluents, based on similarities of the industrial activities, significant materials, size of drainage areas, and storm water management practices occurring within the drainage areas of the outfalls, the permittee may conduct visual monitoring on the effluent of just one of the outfalls and report that the quantitative data also applies to the substantially identical outfall(s). The permittee shall include the following information in the SWPPP:

(a) The locations of the outfalls;

(b) Why the outfalls are expected to discharge substantially identical effluents, including evaluation of monitoring data, where available;

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

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

(6) If a facility's permit coverage is effective less than one month from the end of a quarterly monitoring period, the first quarterly period starts with the next respective quarterly monitoring period (e.g., if permit coverage begins March 5, the permittee will not need to start quarterly visual monitoring until the April-June quarter).

b. Benchmark monitoring of discharges associated with specific industrial activities.

Table 70-1 identifies the specific industrial sectors subject to the benchmark monitoring requirements of this permit and the industry-specific pollutants of concern. The permittee must shall refer to the tables found in the individual sectors in Part IV (9VAC25-151-90 et seq.) for benchmark monitoring cut-off concentrations concentration values. Colocated industrial activities at the facility that are described in more than one sector in Part IV must shall comply with all applicable benchmark monitoring requirements from each sector.

The results of benchmark monitoring are primarily for the permittee to use to determine the overall effectiveness of the SWPPP in controlling the discharge of pollutants to receiving waters. Benchmark concentration values, included in Part IV of this permit, are not viewed as effluent limitations. An exceedance Exceedance of a benchmark value concentration does not, in and of itself, constitute a violation of this permit. While exceedance of a benchmark value and does not automatically indicate that violation of a water quality standard has occurred; however, it does signal that modifications to the SWPPP may be are necessary, unless justification is provided in the comprehensive site compliance evaluation (Part III E). In addition, exceedance of benchmark values concentrations may identify facilities that would be more appropriately covered under an individual, or alternative general permit where more specific pollution prevention controls could be required.

1Table does not include parameters for compliance monitoring under effluent limitations guidelines.
2See Sector G (Part IV G) for additional monitoring discharges from waste rock and overburden piles from active ore mining or dressing facilities, inactive ore mining or dressing facilities, and sites undergoing reclamation.
3Monitoring requirement is for airports with deicing activities that utilize more than 100 tons of urea or more than 100,000 gallons of glycol per year.

(1) (a) If a facility falls within a sector(s) required to conduct benchmark monitoring, monitoring shall be performed at least once during each of the first two, and potentially all, monitoring periods after the facility is granted coverage under the permit. Depending on the results of two consecutive monitoring periods, benchmark monitoring may not be required to be conducted in subsequent monitoring periods (see subsection (2) below).

(b) Monitoring periods for benchmark monitoring. Unless otherwise specified in Part IV, the The benchmark monitoring period is July 1 to June 30 each year of the permit. If a facility falls within a sector(s) required to conduct benchmark monitoring, monitoring must be performed annually (once per year) during at least the first two, and potentially all, monitoring periods, unless otherwise specified in the sector-specific requirements of Part IV. Depending on the results of two consecutive monitoring years, benchmark monitoring may not be required to be conducted in subsequent monitoring years (see subsection (2) below) periods are as follows: (i) July 1, 2009, to December 31, 2009; (ii) January 1, 2010, to December 31, 2010; (iii) January 1, 2011, to December 31, 2011; (iv) January 1, 2012, to December 31, 2012; and, (v) January 1, 2013, to December 31, 2013.

(c) If a facility's permit coverage is effective less than one month from the end of a monitoring period, the facility's first monitoring period starts with the next respective monitoring period (e.g., if permit coverage begins December 5, the permittee will not need to start sampling until the next January-December monitoring period).

(2) Benchmark monitoring waivers for facilities testing below benchmark concentration values. All of the provisions of this subpart are available to permittees except as noted in Part IV. Waivers from benchmark monitoring are available to facilities whose discharges are below benchmark concentration values, thus there is an incentive for facilities to improve the effectiveness of their SWPPPs in eliminating discharges of pollutants and avoid the cost of monitoring. On both a parameter by parameter and on an outfall by outfall basis, sector-specific. Sector-specific benchmark monitoring is not required to be conducted in subsequent monitoring years periods during the term of this permit provided:

(a) Samples were collected in two consecutive monitoring years periods, and all the parameter concentrations were below the applicable benchmark value concentration values in Part IV; and

(b) The facility is not subject to a numeric limitation for that parameter established in Part I A 1 c (Coal Pile Runoff) (Storm Water Effluent Limitations, Coal Pile Runoff, and TMDL Wasteload Allocations) or Part IV (Sector Specific Permit Requirements); and

(c) A waiver request is submitted to and approved by the department. The waiver request should shall be sent to the appropriate regional office, along with the supporting monitoring data for two consecutive years monitoring periods, and a certification that, based on current potential pollutant sources and BMPs used, discharges from the facility are reasonably expected to be essentially the same (or cleaner) compared to when the benchmark monitoring for the two consecutive monitoring years periods was done.

Waiver requests will be evaluated by the department based upon: (i) benchmark monitoring results below the benchmark concentration values; (ii) a favorable compliance history (including inspection results); and (iii) no outstanding enforcement actions.

The monitoring waiver may be revoked by the department for just cause. The permittee will be notified in writing that the monitoring waiver is revoked, and that the benchmark monitoring requirements are again in force and will remain in effect until the permit's expiration date.

(3) Samples must shall be collected and analyzed in accordance with Part I A 2 b. For each outfall, one signed Discharge Monitoring Report (DMR) form must shall be maintained on-site with the SWPPP submitted to the department for each storm event sampled. Monitoring results must shall be retained in accordance with Part II B.

(4) Inactive and unstaffed sites. If the permittee is unable to conduct benchmark monitoring at an inactive and unstaffed site, a waiver of the monitoring requirement may be exercised as long as the facility remains inactive and unstaffed, and there are no industrial materials or activities exposed to storm water. If the permittee exercises this waiver, a certification must shall be submitted to the department and maintained with the SWPPP stating that the site is inactive and unstaffed, there are no industrial materials or activities exposed to storm water, and that performing benchmark monitoring during a qualifying storm event is not feasible. The waiver must shall be signed and certified in accordance with Part II K.

(5) Representative outfalls - essentially identical discharges. If the facility has two or more outfalls that discharge substantially identical effluents, based on similarities of the industrial activities, significant materials, size of drainage areas, and storm water management practices occurring within the drainage areas of the outfalls, the permittee may perform benchmark monitoring on the effluent of just one of the outfalls and report that the quantitative data also applies to the substantially identical outfall(s). The permittee shall include the following information in the SWPPP, and in any DMRs that are required to be submitted to the department:

(a) The locations of the outfalls;

(b) Why the outfalls are expected to discharge substantially identical effluents, including evaluation of monitoring data, where available;

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

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

c. Coal pile runoff.

(1) Facilities with discharges of storm water from coal storage piles must comply with the limitations and monitoring requirements of Table 70-2 for all discharges containing the coal pile runoff, regardless of the facility's sector of industrial activity. Permittees shall monitor such storm water discharges at least annually (once per year).

(2) The coal pile runoff must not be diluted with storm water or other flows in order to meet this limitation.

(3) If a facility is designed, constructed and operated to treat the volume of coal pile runoff that is associated with a 10-year, 24-hour rainfall event, any untreated overflow of coal pile runoff from the treatment unit is not subject to the 50 mg/L limitation for total suspended solids.

(4) Samples must be collected and analyzed in accordance with Part I A 2 b. Monitoring results must be reported in accordance with Part I A 4 and Part II C, and retained in accordance with Part II B.

Parameter	Limit	Monitoring Frequency	Sample Type
Total Suspended Solids (TSS)	50 mg/l, max	1/year	Grab
pH	6.0 - 9.0 min. and max	1/year	Grab

d. c. Compliance monitoring for discharges subject to numerical effluent limitation guidelines limitations.

(1) Facilities subject to storm water effluent limitation guidelines.

(a) Facilities subject to storm water effluent limitation guidelines (see Table 70-2) are required to monitor such discharges to evaluate compliance with numerical effluent limitations. Industry-specific numerical limitations and compliance monitoring requirements are described in Part IV of the permit (9VAC25-151-90 et seq.). Colocated industrial activities at the facility that are described in more than one sector in Part IV must shall comply on a discharge-by-discharge basis with all applicable effluent limitations from each sector.

(b) Permittees shall monitor the discharges for the presence of the pollutant subject to the effluent limitation at least annually (once per year) once during each of the monitoring periods after the facility is granted coverage under the permit. If a facility's permit coverage is effective less than one month from the end of a monitoring period, the facility's first monitoring period starts with the next respective monitoring period (e.g., if permit coverage begins December 5, the permittee will not need to start the effluent limitation monitoring until the next January-December monitoring period).

(c) The monitoring periods for effluent limitation monitoring are as follows: (i) July 1, 2009, to December 31, 2009; (ii) January 1, 2010, to December 31, 2010; (iii) January 1, 2011, to December 31, 2011; (iv) January 1, 2012, to December 31, 2012; and (v) January 1, 2013, to December 31, 2013.

(2) Facilities subject to coal pile runoff monitoring.

(a) Facilities with discharges of storm water from coal storage piles shall comply with the limitations and monitoring requirements of Table 70-3 for all discharges containing the coal pile runoff, regardless of the facility's sector of industrial activity.

(b) Permittees shall monitor such storm water discharges at least once during each of the monitoring periods after the facility is granted coverage under the permit. If a facility's permit coverage is effective less than one month from the end of a monitoring period, the facility's first monitoring period starts with the next respective monitoring period (e.g., if permit coverage begins December 5, the permittee will not need to start the coal pile runoff monitoring until the next January-December monitoring period).

(c) Coal pile runoff monitoring periods are as follows: (i) July 1, 2009, to December 31, 2009; (ii) January 1, 2010, to December 31, 2010; (iii) January 1, 2011, to December 31, 2011; (iv) January 1, 2012, to December 31, 2012; and (v) January 1, 2013, to December 31, 2013.

(d) The coal pile runoff shall not be diluted with other storm water or other flows in order to meet this limitation.

(e) If a facility is designed, constructed and operated to treat the volume of coal pile runoff that is associated with a 10-year, 24-hour rainfall event, any untreated overflow of coal pile runoff from the treatment unit is not subject to the 50 mg/L limitation for total suspended solids.

(f) Samples shall be collected and analyzed in accordance with Part I A 2. Monitoring results shall be reported in accordance with Part I A 4 and Part II C, and retained in accordance with Part II B.

TABLE 70-3. NUMERIC LIMITATIONS FOR COAL PILE RUNOFF.
Parameter	Limit	Monitoring Frequency	Sample Type
Total Suspended Solids (TSS)	50 mg/l, max.	1/year	Grab
pH	6.0 min. - 9.0 max.	1/year	Grab

(3) Facilities subject to Total Maximum Daily Load (TMDL) wasteload allocations.

(a) Upon written notification from the department, facilities subject to TMDL wasteload allocations will be required to monitor such discharges to evaluate compliance with the TMDL requirements.

(b) Permittees shall monitor the discharges for the pollutant subject to the TMDL wasteload allocation at least semiannually (twice per year). The TMDL semiannual monitoring periods are from July 1 to December 31, and January 1 to June 30. If a facility's notification that they are subject to the TMDL monitoring requirements is effective less than one month from the end of a semiannual monitoring period, the facility's first monitoring period starts with the next respective monitoring period (e.g., if notification is given on December 5, the permittee will not need to start semiannual monitoring until the next January 1 to June 30 monitoring period).

(c) Samples shall be collected and analyzed in accordance with Part I A 2. Monitoring results shall be reported in accordance with Part I A 4 and Part II C, and retained in accordance with Part II B.

2. Monitoring instructions.

a. Monitoring periods. Permittees that are required to conduct monitoring on an annual or quarterly basis must collect samples within the following time periods (unless otherwise specified in Part IV):

(1) The monitoring year is from July 1 to June 30.

(2) If a facility's permit coverage was effective less than one month from the end of a quarterly or yearly monitoring period, the first monitoring period starts with the next respective monitoring period (e.g., if permit coverage begins March 5, the permittee would not need to start quarterly sampling until the April-June quarter, but the permittee would only have from March 5 to June 30 to complete that year's annual monitoring).

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

b. When and How to Sample. A minimum of one grab sample must shall be taken from the discharge associated with industrial activity resulting from a storm event with at least that is greater than 0.1 inch of precipitation in magnitude (defined as a "measurable" event), providing the interval from the preceding measurable storm is at least 72 hours. The 72-hour storm interval is waived when the preceding measurable storm did not yield a measurable discharge, or if the permittee is able to document that less than a 72-hour interval is representative for local storm events during the sampling period.

The grab sample must 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 provided that the permittee explains why a grab sample during the first 30 minutes was impracticable. This information must shall be submitted on or with the Discharge Monitoring Report (DMR), or maintained with the SWPPP if reports are not required to be submitted. If the sampled discharge commingles with process or nonprocess water, the permittee must shall attempt to sample the storm water discharge before it mixes with the nonstorm water.

c. Storm event data. Along with the monitoring results, the permittee must shall provide the date and duration (in hours) of the storm event(s) sampled; rainfall measurements or estimates (in inches) of the storm event that generated the sampled runoff; the duration between the storm event sampled and the end of the previous measurable (greater than 0.1 inch rainfall) storm event; and an estimate of the total volume (in gallons) of the discharge sampled.

d. Representative outfalls—essentially identical discharges. If a facility has two or more outfalls that discharge substantially identical effluents, based on similarities of the industrial activities, significant materials or storm water management practices occurring within the drainage areas of the outfalls, the permittee may test the effluent of just one of the outfalls and report that the quantitative data also applies to the substantially identical outfall(s). This outfall monitoring waiver for substantially identical discharges applies to quarterly visual monitoring as well, but does not apply to compliance monitoring for discharges subject to numerical effluent limitation guidelines (see Part I A 1 d (2)). The permittee must include the following information in the SWPPP, and in any DMRs that are required to be submitted to the department:

(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%).

d. Documentation explaining a facility's inability to obtain a sample (including dates/times the outfalls were viewed and/or sampling was attempted), of no rain event, or of no "measurable" storm event shall be maintained with the SWPPP. Acceptable documentation includes, but is not limited to, NCDC weather station data, local weather station data, facility rainfall logs, and other appropriate supporting data.

3. Monitoring waivers. Unless specifically stated otherwise, the following waivers may be applied to any monitoring required under this permit.

a. 3. Adverse climatic conditions waiver. When adverse weather conditions prevent the collection of samples, a substitute sample may be taken during a qualifying storm event in the next monitoring period. Adverse weather conditions are those that are dangerous or create inaccessibility for personnel, and may include such things as local flooding, high winds, electrical storms, or situations that otherwise make sampling impracticable, such as drought or extended frozen conditions. Unless specifically stated otherwise, this waiver may be applied to any monitoring required under this permit.

b. Alternative certification of "Not Present" or "No Exposure."

The permittee is not subject to the benchmark monitoring requirements of Part I A 1 b provided:

(1) A certification is made for a given outfall, or on a pollutant-by-pollutant basis in lieu of monitoring required under Part I A 1 b, that material handling equipment or activities, raw materials, intermediate products, final products, waste materials, by-products, industrial machinery or operations, or significant materials from past industrial activity that are located in areas of the facility within the drainage area of the outfall are not presently exposed to storm water and are not expected to be exposed to storm water for the certification period; and

(2) The certification is signed in accordance with Part II K, submitted to the department, and a copy retained with the SWPPP; and

(3) If certification cannot be made for an entire period, the permittee must document the date exposure was eliminated and must perform any monitoring required up until that date; and

(4) No numeric limitation for that parameter is established in Part IV.

4. Reporting monitoring results.

a. Reporting to the department. Depending on the types of monitoring required at a permitted facility, monitoring results may have to be submitted to the department, or they may only have to be kept with the SWPPP. The permittee must shall follow the reporting requirements and deadlines below for the types of monitoring that apply to the facility:

TABLE 70-4. MONITORING REPORTING REQUIREMENTS.
Monitoring for Numeric Limitation Effluent Limitations (other than TMDL Wasteload Allocations)	Submit results on a DMR by the 10th day of the month after monitoring takes place January 30.
Semiannual Monitoring for TMDL Wasteload Allocations	Submit results on a DMR by January 30 and by July 30.
Benchmark Monitoring	Retain results with SWPPP - do not submit unless requested to do so by the department. Submit results on a DMR by January 30.
Biannual Annual Monitoring for Metal Mining Facilities (see Part IV, Sector G)	Retain results with SWPPP - do not submit unless requested to do so by the department.
Quarterly Visual Monitoring	Retain results with SWPPP - do not submit unless requested to do so by the department.
Follow-up Monitoring (see subsection A 5 c below).	Submit results on a DMR no later than 30 days after the results are received.

Permittees that are required to submit monitoring shall submit results for each outfall associated with industrial activity according to the requirements of Part II C. For each outfall, one signed discharge monitoring report (DMR) form must shall be submitted to the department per storm event sampled.

b. Additional reporting. In addition to filing copies of discharge monitoring reports in accordance with Part II C, permittees with at least one storm water discharge associated with industrial activity through a municipal separate storm sewer system (MS4), or a municipal system designated by the director, must submit signed copies of DMRs to the MS4 operator at the same time. Permittees not required to report monitoring data and permittees that are not otherwise required to monitor their discharges need not comply with this provision. Significant digits. The permittee shall report at least the same number of significant digits as a numeric effluent limitation or TMDL wasteload allocation for a given parameter; otherwise, at least two significant digits shall be reported for a given parameter. Regardless of the rounding convention used by the permittee (i.e., five always rounding up or to the nearest even number), the permittee shall use the convention consistently and shall ensure that consulting laboratories employed by the permittee use the same convention.

5. Corrective actions.

a. Data exceeding benchmarks concentration values. If the benchmark monitoring result exceeds the benchmark concentration value for that parameter, the permittee must review the SWPPP and modify it as necessary to address any deficiencies that caused the exceedance. Revisions to the SWPPP must be completed within 30 days after an exceedance is discovered. When BMPs need to be modified or added (distinct from regular preventive maintenance of existing BMPs described in Part III C), implementation must be completed before the next anticipated storm event if possible, but no later than 60 days after the exceedance is discovered, or as otherwise provided or approved by the department. Any BMP modifications must be documented and dated, and retained with the SWPPP, along with the amount of time taken to modify the applicable BMPs or implement additional BMPs.

b. Corrective actions. The permittee must take corrective action whenever:

(1) Routine facility inspections, comprehensive site compliance evaluations, inspections by local, state or federal officials, or any other process, observation or event result in discovery of any deficiency; or

(2) There is any exceedance of an effluent limitation (including coal pile runoff), TMDL wasteload allocation, or water quality standard.

The permittee must review the SWPPP and modify it as necessary to address any deficiencies. Revisions to the SWPPP must be completed within 30 days following the discovery of the deficiency. When BMPs need to be modified or added (distinct from regular preventive maintenance of existing BMPs described in Part III C), implementation must be completed before the next anticipated storm event if possible, but no later than 60 days after the deficiency is discovered, or as otherwise provided or approved by the department. The amount of time taken to modify a BMP or implement additional BMPs must be documented in the SWPPP.

Any corrective actions taken must be documented and retained with the SWPPP. Reports of corrective actions must be signed in accordance with Part II K.

c. Follow-up monitoring and reporting. If at any time monitoring results indicate that discharges from the facility exceed an effluent limitation or a TMDL wasteload allocation, or that discharges from the facility are causing or contributing to an exceedance of a water quality standard, immediate steps must be taken to eliminate the exceedances in accordance with the above Part I A 5 b (Corrective actions). Within 30 calendar days of implementing the relevant corrective action(s) (or during the next qualifying runoff event, should none occur within 30 calendar days) follow-up monitoring must be undertaken to verify that the BMPs that were modified are effectively protecting water quality. Follow-up monitoring need only be conducted for pollutant(s) with prior exceedances unless there are reasons to believe that facility modifications may have reduced pollutant prevention or removal capacity for other pollutants of concern.

The follow-up monitoring data must be submitted to the department no later than 30 days after the results are received. If the follow-up monitoring value does not exceed the effluent limitation or other relevant standard, no additional follow-up monitoring is required for this monitoring event.

Should the follow-up monitoring indicate that the effluent limitation, TMDL wasteload allocation, water quality standard or other relevant standard is still being exceeded, an exceedance report must be submitted to the department no later than 30 days after the follow-up monitoring results are received. The following information must be included in the report: permit number; facility name, address and location; receiving water; monitoring data from this and the preceding monitoring event(s); an explanation of the situation; description of what has been done and the intended actions (should the corrective actions not yet be complete) to further reduce pollutants in the discharge; and an appropriate contact name and phone number. Additional follow-up monitoring must be continued at an appropriate frequency, but no less often than quarterly, until the discharge no longer exceeds the standard.

B. Special conditions.

1. Allowable nonstorm water discharges. Except as provided in this section or in Part IV (9VAC25-151-90 et seq.), all discharges covered by this permit shall be composed entirely of storm water. The following nonstorm water discharges are authorized by this permit provided the nonstorm water component of the discharge is in compliance with Part III D 2 (Nonstorm water discharges) of this general permit:

2. Releases of hazardous substances or oil in excess of reportable quantities. The discharge of hazardous substances or oil in the storm water discharge(s) from the facility shall be prevented or minimized in accordance with the storm water pollution prevention plan for the facility. This permit does not authorize the discharge of hazardous substances or oil resulting from an on-site spill. This permit does not relieve the permittee of the reporting requirements of 40 CFR Part 110 (2002) (2007), 40 CFR Part 117 (2002) (2007) and 40 CFR Part 302 (2002) (2007) or § 62.1-44.34:19 of the Code of Virginia.

Where a release containing a hazardous substance or oil in an amount equal to or in excess of a reportable quantity established under either 40 CFR Part 110 (2002) (2007), 40 CFR Part 117 (2002) (2007) or 40 CFR Part 302 (2002) (2007) occurs during a 24-hour period:

a. The permittee is required to notify the department in accordance with the requirements of Part II G as soon as he has knowledge of the discharge;

b. Where a release enters a municipal separate storm sewer system (MS4), the permittee shall also notify the owner of the MS4; and

c. The storm water pollution prevention plan required under Part III must shall be reviewed to identify measures to prevent the reoccurrence of such releases and to respond to such releases, and the plan must shall be modified where appropriate.

3. Colocated industrial activity. If the facility has industrial activities occurring on-site which are described by any of the activities in Part IV of the permit (9VAC25-151-90 et seq.), those industrial activities are considered to be colocated industrial activities. Storm water discharges from colocated industrial activities are authorized by this permit, provided that the permittee complies with any and all additional pollution prevention plan and monitoring requirements from Part IV applicable to that particular colocated industrial activity. The permittee shall determine which additional pollution prevention plan and monitoring requirements are applicable to the colocated industrial activity by examining the narrative descriptions of each coverage section (Discharges covered under this section).

4. The storm water discharges authorized by this permit may be combined with other sources of storm water which are not required to be covered under a VPDES permit, so long as the combined discharge is in compliance with this permit.

5. There shall be no discharge of floating solids or visible foam in other than trace amounts.

6. Additional requirements for salt Salt storage piles or piles containing salt. Storage piles of salt or piles containing salt used for deicing or other commercial or industrial purposes must shall be enclosed or covered to prevent exposure to precipitation (except for exposure resulting from adding or removing materials from the pile). Piles do not need to be enclosed or covered where storm water from the pile is not discharged to state waters or the discharges from the piles are authorized under another permit. The permittee shall implement appropriate measures (e.g., good housekeeping, diversions, containment) to minimize exposure resulting from adding to or removing materials from the pile. All salt storage piles shall be located on an impervious surface. All runoff from the pile, and/or runoff that comes in contact with salt, including under drain systems, shall be collected and contained within a basin lined with concrete or other impermeable materials. This lined basin shall be bermed and shall be sized to contain runoff resulting from a 24-hour 25-year storm event. In no case shall salt contaminated stormwater be allowed to discharge directly to the ground or to state waters.

7. Discharges to waters subject to TMDL wasteload allocations. Facilities that are an identified source of the specified pollutant of concern to waters for which a "total maximum daily load" (TMDL) wasteload allocation has been established by the board and approved by EPA prior to the term of this permit shall incorporate measures and controls into the SWPPP required by Part III that are consistent with the assumptions and requirements of the TMDL. The department will provide written notification to the owner that a facility is subject to the TMDL requirements. The facility's SWPPP shall specifically address any conditions or requirements included in the TMDL that are applicable to discharges from the facility. If the TMDL establishes a specific numeric wasteload allocation that applies to discharges from the facility, the owner shall incorporate that allocation into the facility's SWPPP, perform any required monitoring in accordance with Part I A 1 c (3), and implement measures necessary to meet that allocation.

7. 8. Water quality protection. The permittee must shall select, install, implement and maintain best management practices (BMPs) at the facility that minimize pollutants in the storm water discharges as necessary to meet applicable water quality standards. If there is evidence indicating that the storm water discharges authorized by this permit are causing, have the reasonable potential to cause, or are contributing to an excursion above an applicable water quality standard, an excursion above a TMDL wasteload allocation, or are causing downstream pollution (as defined in § 62.1-44.3 of the Code of Virginia), the board may take appropriate enforcement action, may require the permittee to include and implement appropriate controls in the SWPPP to correct the problem, and/or may require the permittee to obtain an individual permit in accordance with 9VAC25-31-170 B 3.

9. Adding/deleting storm water outfalls. The permittee may add new and/or delete existing storm water outfalls at the facility as necessary/appropriate. The permittee shall update the SWPPP and notify the department of all outfall changes within 30 days of the change. The permittee shall submit a copy of the updated SWPPP site map with their notification.

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 II 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 II 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 II 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 cause(s) 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 II I; and

d. The permittee complied with any remedial measures required under Part II 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 an authorized representative, 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;

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 II 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 II Y 1, this permit may be automatically transferred to a new permittee if:

a. The current permittee notifies the department at least 30 days in advance of the proposed transfer of the title to the facility or property;

b. 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

All shall be implemented for all the areas identified in Part III B 3 (summary of potential pollutant sources) should have a BMP(s) identified for the area's discharges. For areas where BMPs are not currently in place, include a description of appropriate BMPs that will be used to control pollutants in storm water discharges. to prevent or control pollutants in storm water discharges from the facility. All reasonable steps shall be taken to control or address the quality of discharges from the site that may not originate at the facility. The SWPPP shall describe the type, location and implementation of all BMPs for each area where industrial materials or activities are exposed to storm water.

Selection of BMPs should shall take into consideration:

(1) The quantity and nature of the pollutants, and their potential to impact the water quality of receiving waters;

(2) Opportunities to combine the dual purposes of water quality protection and local flood control benefits, including physical impacts of high flows on streams (e.g., bank erosion, impairment of aquatic habitat, etc.);

(3) Opportunities to offset the impact of impervious areas of the facility on ground water recharge and base flows in local streams, taking into account the potential for ground water contamination.

(1) That preventing storm water from coming into contact with polluting materials is much more effective than trying to remove pollutants from storm water;

(2) BMPs generally shall be used in combination with each other for most effective water quality protection;

(3) The type and quantity of pollutants, including their potential to impact receiving water quality;

(4) That minimizing impervious areas at the facility will reduce runoff and improve groundwater recharge and stream base flows in local streams (taking into account the potential for ground water contamination);

b. BMP types to be considered. The permittee must consider shall implement the following types of structural, nonstructural and other BMPs for implementation at to prevent and control pollutants in the storm water discharges from the facility, unless it can be demonstrated and documented that such controls are not relevant to the discharges (e.g., there are no storage piles containing salt). The SWPPP shall describe how each BMP is, or will be, implemented. If this requirement was fulfilled with the area-specific BMPs identified under Part III B 6 a, then the previous description is sufficient. However, many of the following BMPs may be more generalized or non-site-specific and therefore not previously considered. If the permittee determines that any of these BMPs are not appropriate for the facility, an explanation of why they are not appropriate shall be included in the plan. The BMP examples listed below are not intended to be an exclusive list of BMPs that may be used. The permittee is encouraged to keep abreast of SWPPP shall incorporate, as appropriate, new BMPs or new applications of existing BMPs to find for the most cost effective means of permit compliance for the facility achieving water quality protection. If BMPs are being used or planned at the facility that are not listed here (e.g., replacing a chemical with a less toxic alternative, adopting a new or innovative BMP, etc.), descriptions of them shall be included in this section of the SWPPP.

(1) Nonstructural BMPs.

(a) (1) Good housekeeping. The permittee must shall keep clean all exposed areas of the facility in a clean, orderly manner where such exposed areas could contribute that are potential sources of pollutants to storm water discharges. Common Typical problem areas include areas around trash containers, storage areas and, loading docks, and vehicle fueling and maintenance areas.

The introduction of raw, final or waste materials to exposed areas of the facility shall be minimized to the maximum extent practicable. The generation of dust, along with off-site vehicle tracking of raw, final or waste materials, or sediments, shall be minimized to the maximum extent practicable.

(b) Minimizing (2) Eliminating and minimizing exposure. Where To the extent practicable, industrial materials and activities should shall be located inside, or protected by a storm-resistant shelter covering to prevent exposure to rain, snow, snowmelt, or and runoff. Note: Eliminating exposure at all industrial areas may make the facility eligible for the "Conditional Exclusion for No Exposure" provision of 9VAC25-31-120 F, thereby eliminating the need to have a permit.

(c) (3) Preventive maintenance. The permittee must shall have a preventive maintenance program that includes timely inspection and maintenance of storm water management devices (e.g., cleaning oil/water separators, catch basins), as well as regular inspection, testing, maintenance and repairing of facility all industrial equipment and systems to avoid breakdowns or failures that could result in discharges of pollutants to surface waters leaks, spill and other releases. This program is in addition to the specific BMP maintenance required under Part III C (Maintenance of BMPs).

(d) (4) Spill prevention and response procedures. The plan must shall describe the procedures that will be followed for cleaning up preventing and responding to spills or and leaks. The procedures and necessary spill response equipment must be made available to those employees who may cause or detect a spill or leak. Where appropriate, the plan must include an explanation of existing or planned material handling procedures, storage requirements, secondary containment, and equipment (e.g., diversion valves), that are intended to minimize spills or leaks at the facility.

(a) Preventive measures include barriers between material storage and traffic areas, secondary containment provisions, and procedures for material storage and handling.

(b) Response procedures shall include notification of appropriate facility personnel, emergency agencies, and regulatory agencies, and procedures for stopping, containing and cleaning up spills. Measures for cleaning up hazardous material spills or leaks must shall be consistent with applicable RCRA regulations at 40 CFR Part 264 (2002) (2007) and 40 CFR Part 265 (2002) (2007). Employees who may cause, detect or respond to a spill or leak shall be trained in these procedures and have necessary spill response equipment available. If possible, one of these individuals shall be a member of the Pollution Prevention Team.

(c) Contact information for individuals and agencies that must be notified in the event of a spill shall be included in the SWPPP, and in other locations where it will be readily available.

(e) (5) Routine facility inspections. Facility personnel who are familiar with the industrial activity, the BMPs and the storm water pollution prevention plan possess the knowledge and skills to assess conditions and activities that could impact storm water quality at the facility, and who can also evaluate the effectiveness of BMPs shall be identified to regularly inspect all areas of the facility where industrial materials or activities are exposed to storm water. These inspections are in addition to, or as part of, the comprehensive site evaluation required under Part III E, and must shall include an evaluation assessment of how well the existing storm water BMPs are operating. At least one member of the Pollution Prevention Team shall participate in the routine facility inspections.

The inspection frequency shall be specified in the plan based upon a consideration of the level of industrial activity at the facility, but shall be a minimum of quarterly unless more frequent intervals are specified elsewhere in the permit or written approval is received from the department for less frequent intervals. The requirement for routine facility inspections is waived for facilities that have maintained an active E3/E4 status.

Any deficiencies in the implementation of the SWPPP that are found must shall be corrected as soon as practicable, but not later than within 14 30 days of the inspection, unless permission for a later date is granted in writing by the director. The results of the inspections must shall be documented in the SWPPP, along with the date(s) and description(s) of any corrective actions that were taken in response to any deficiencies or opportunities for improvement that were identified.

(f) (6) Employee training. The SWPPP must describe the permittee shall implement a storm water employee training program for the facility.

Employee training must Training shall be provided for all employees who work in areas where industrial materials or activities are exposed to storm water, and for employees who are responsible for implementing activities identified in the SWPPP (e.g., inspectors, maintenance people) (e.g., inspectors, maintenance personnel, etc.), and for all members of the Pollution Prevention Team. The training should inform employees of The training shall cover the components and goals of the SWPPP, and include such topics as spill response, good housekeeping, material management practices, BMP operation and maintenance, etc. The SWPPP shall include a summary of any training performed.

(2) Structural BMPs.

(a) (7) Sediment and erosion control. The plan shall identify areas at the facility that, due to topography, land disturbance (e.g., construction) (e.g., construction, landscaping, site grading), or other factors, have a potential for significant soil erosion. The plan must permittee shall identify and implement structural, vegetative, and/or stabilization BMPs that will be implemented to limit prevent or control on-site and off-site erosion and sedimentation. Flow velocity dissipation devices shall be placed at discharge locations and along the length of any outfall channel if the flows would otherwise create erosive conditions.

(b) (8) Management of runoff. The plan shall describe the traditional storm water runoff management practices (permanent structural BMPs other than those that control the generation or source(s) of pollutants) that currently exist or that are planned (i.e., permanent structural BMPs) for the facility. These types of BMPs are typically used to divert, infiltrate, reuse, or otherwise reduce pollutants in storm water discharges from the site. The plan shall provide that all measures that the permittee determines to be reasonable and appropriate, or are required by a state or local authority shall be implemented and maintained. Factors for the permittee to consider when selecting appropriate BMPs should include:

(i) The industrial materials and activities that are exposed to storm water, and the associated pollutant potential of those materials and activities; and

(ii) The beneficial and potential detrimental effects on surface water quality, ground water quality, receiving water base flow (dry weather stream flow), and physical integrity of receiving waters.

Structural measures should be placed on upland soils, avoiding wetlands and floodplains, if possible. Structural BMPs may require a separate permit under § 404 of the CWA and the Virginia Water Protection Permit Program Regulation (9VAC25-210) before installation begins.

(c) Example BMPs. BMPs that could be used include but are not limited to: storm water detention structures (including wet ponds); storm water retention structures; flow attenuation by use of open vegetated swales and natural depressions; infiltration of runoff on-site; and sequential systems (which combine several practices).

1. Site description.

a. Site map. The site map shall identify where any of the following activities may be exposed to precipitation/surface runoff: storage or disposal of wastes such as spent solvents/baths, sand, slag/dross; liquid storage tanks/drums; processing areas including pollution control equipment (e.g., baghouses); and storage areas of raw materials such as coal, coke, scrap, sand, fluxes, refractories, or metal in any form. In addition, indicate sources where an accumulation of significant amounts of particulate matter could occur from such sources as furnace or oven emissions, losses from coal/coke handling operations, etc., and that could result in a discharge of pollutants to surface waters.

b. Inventory of exposed materials Summary of potential pollutant sources. The inventory of materials handled at the site that potentially may be exposed to precipitation/runoff should shall include areas where deposition of particulate matter from process air emissions or losses during material handling activities are possible.

2. Storm water controls.

a. Good housekeeping. The SWPPP should shall consider implementation of the following measures, or equivalent measures, where applicable.

(1) Establishment of a cleaning/maintenance program for all impervious areas of the facility where particulate matter, dust, or debris may accumulate, especially areas where material loading/unloading, storage, handling, and processing occur.

(2) The paving of areas where vehicle traffic or material storage occur, but where vegetative or other stabilization methods are not practicable. Sweeping programs shall be instituted in these areas as well.

(3) For unstabilized areas of the facility where sweeping is not practical, the permittee should shall consider using storm water management devices such as sediment traps, vegetative buffer strips, filter fabric fence, sediment filtering boom, gravel outlet protection, or other equivalent measures, that effectively trap or remove sediment.

b. Routine facility inspections. Inspections shall be conducted at least quarterly monthly, and shall address all potential sources of pollutants, including (if applicable):

(1) Air pollution control equipment (e.g., baghouses, electrostatic precipitators, scrubbers, and cyclones) should shall be inspected for any signs of degradation (e.g., leaks, corrosion, or improper operation) that could limit their efficiency and lead to excessive emissions. The permittee should shall consider monitoring air flow at inlets/outlets, or equivalent measures, to check for leaks (e.g., particulate deposition) or blockage in ducts;

9VAC25-151-150. Sector G - Metal mining (ore mining and dressing).

A. Discharges covered under this section. The requirements listed under this section apply to storm water discharges associated with industrial activity from active, temporarily inactive and inactive metal mining and ore dressing facilities including mines abandoned on federal lands, as classified under SIC Major Group 10. Coverage is required for facilities that discharge storm water that has come into contact with, or is contaminated by, any overburden, raw material, intermediate product, finished product, byproduct, or waste product located on the site of the operation. SIC Major Group 10 includes establishments primarily engaged in mining of ores, developing mines, or exploring for metallic minerals (ores) and also includes ore dressing and beneficiating operations, whether performed at colocated, dedicated mills or at separate mills, such as custom mills. For the purposes of this section, the term "metal mining" includes any of the separate activities listed above. Covered discharges include:

1. All storm water discharges from inactive metal mining facilities; and

2. Storm water discharges from the following areas of active and temporarily inactive metal mining facilities: waste rock/overburden piles if composed entirely of storm water and not combining with mine drainage; topsoil piles; off-site haul/access roads; on-site haul/access roads constructed of waste rock/overburden if composed entirely of storm water and not combining with mine drainage; on-site haul/access roads not constructed of waste rock/overburden/spent ore except if mine drainage is used for dust control; runoff from tailings dams/dikes when not constructed of waste rock/tailings and no process fluids are present; runoff from tailings dams/dikes when constructed of waste rock/tailings and no process fluids are present if composed entirely of storm water and not combining with mine drainage; concentration building if no contact with material piles; mill site if no contact with material piles; office/administrative building and housing if mixed with storm water from industrial area; chemical storage area; docking facility if no excessive contact with waste product that would otherwise constitute mine drainage; explosive storage; fuel storage; vehicle/equipment maintenance area/building; parking areas (if necessary); power plant; truck wash areas if no excessive contact with waste product that would otherwise constitute mine drainage; unreclaimed, disturbed areas outside of active mining area; reclaimed areas released from reclamation bonds prior to December 17, 1990; and partially/inadequately reclaimed areas or areas not released from reclamation bonds;

3. Storm water discharges from exploration and development of metal mining and/or ore dressing facilities; and

4. Storm water discharges from facilities at mining sites undergoing reclamation.

B. Limitations on coverage. Storm water discharges from active metal mining facilities that are subject to the effluent limitation guidelines for the Ore Mining and Dressing Point Source Category (40 CFR Part 440 (2002)) (2007)) are not authorized by this permit.

Note: Discharges that come in contact with overburden/waste rock are subject to 40 CFR Part 440 (2002) (2007), providing: the discharges drain to a point source (either naturally or as a result of intentional diversion), and they combine with mine drainage that is otherwise regulated under 40 CFR Part 440 (2002) (2007). Discharges from overburden/waste rock can be covered under this permit if they are composed entirely of storm water and do not combine with sources of mine drainage that are subject to 40 CFR Part 440 (2002) (2007).

C. Special Conditions. Prohibition of nonstorm water discharges. In addition to the general prohibition of nonstorm water discharges in Part I B 1, the following discharges are not covered by this permit: adit drainage or contaminated springs or seeps. Contaminated seeps and springs discharging from waste rock dumps that do not directly result from precipitation events are not authorized by this permit.

D. Special definitions. The following definitions are only for this section of the general permit:

"Active metal mining facility" means a place where work or other related activity to the extraction, removal, or recovery of metal ore is being conducted. For surface mines, this definition does not include any land where grading has returned the earth to a desired contour and reclamation has begun.

"Active phase" means activities including each step from extraction through production of a salable product.

"Exploration and construction development phase" entails exploration and land disturbance activities to determine the financial viability of a site. Construction Development includes the building of site access roads and removal of overburden and waste rock to expose mineable minerals.

"Final stabilization" - a site or portion of a site is “finally stabilized” when:

1. All soil-disturbing activities at the site have been completed and either of the two following criteria are met:

a. A uniform (e.g., evenly distributed, without large bare areas) perennial vegetative cover with a density of 70% of the native background vegetative cover for the area has been established on all unpaved areas and areas not covered by permanent structures, or

(b) Equivalent permanent stabilization measures (such as the use of riprap, gabions, or geotextiles) have been employed.

2. When background native vegetation will cover less than 100% of the ground (e.g., arid areas, beaches), the 70% coverage criteria is adjusted as follows: if the native vegetation covers 50% of the ground, 70% of 50% (0.70 x 0.50 = 0.35) would require 35% total cover for final stabilization. On a beach with no natural vegetation, no stabilization is required.

"Inactive metal mining facility" means a site or portion of a site where metal mining and/or milling occurred in the past but is not an active facility as defined in this permit, and where the inactive portion is not covered by an active mining permit issued by the applicable (federal or state) federal or state governmental agency.

"Mining operation" typically consists of three phases, any one of which individually qualifies as a "mining activity." The phases are the exploration and construction development phase, the active phase, and the reclamation phase.

"Reclamation phase" means activities intended to return the land to its premining use.

"Temporarily inactive metal mining facility" means a site or portion of a site where metal mining and/or milling occurred in the past but currently are not being actively undertaken, and the facility is covered by an active mining permit issued by the applicable (federal or state) federal or state government agency.

E. Clearing, grading, and excavation activities. Clearing, grading, and excavation activities being conducted as part of the exploration and development phase of a mining operation are covered under this permit.

1. Management practices for clearing, grading, and excavation activities.

a. Selecting and installing control measures. A combination of erosion and sedimentation control measures are required to achieve maximum pollutant prevention and removal. All control measures shall be properly selected, installed, and maintained in accordance with any relevant manufacturer specifications and good engineering practices.

b. Removal of sediment. If sediment escapes the site, off-site accumulations of sediment shall be removed at a frequency sufficient to prevent off-site impacts.

c. Good housekeeping. Litter, debris, and chemicals shall be prevented from becoming a pollutant source in storm water discharges.

d. Velocity dissipation. Velocity dissipation devices shall be placed at discharge locations and along the length of any outfall channel to provide a nonerosive flow velocity from disturbed areas and from any storm water retention or detention facilities to a water course so that the natural physical and biological characteristics and functions are maintained and protected (e.g., no significant changes in the hydrological regime of the receiving water).

e. Retention and detention of storm water runoff. For drainage locations serving more than one acre, sediment basins and/or temporary sediment traps should be used. At a minimum, silt fences, vegetative buffer strips, or equivalent sediment controls are required for all down slope boundaries (and for those side slope boundaries deemed appropriate as dictated by individual site conditions) of the development area unless a sediment basin providing storage for a calculated volume of runoff from a two-year, 24-hour storm or 3,600 cubic feet of storage per acre drained is provided.

f. Temporary stabilization of disturbed areas. Stabilization measures shall be initiated immediately in portions of the site where development activities have temporarily or permanently ceased, but in no case more than 14 days after the construction activity in that portion of the site has temporarily or permanently ceased. In arid, semiarid, and drought-stricken areas where initiating perennial vegetative stabilization measures is not possible within 14 days after construction activity has temporarily or permanently ceased, final vegetative stabilization measures shall be initiated as soon as possible. Until full vegetative stabilization is achieved, interim measures such as blankets and tackifiers shall be employed.

2. Requirements for inspection of clearing, grading, and excavation activities.

a. Inspection frequency. Inspections shall be conducted at least once every seven calendar days or at least once every 14 calendar days and within 24 hours of the end of a storm event of 0.5 inches or greater. Inspection frequency may be reduced to at least once every month if the entire site is temporarily stabilized, if runoff is unlikely due to winter conditions (e.g., site is covered with snow, ice, or the ground is frozen), or construction is occurring during seasonal arid periods in arid areas and semi-arid areas.

b. Qualified personnel for inspections. Inspections shall be conducted by qualified personnel. "Qualified personnel" means a person knowledgeable in the principles and practice of erosion and sediment control who possesses the skills to assess conditions at the construction site that could impact storm water quality and the effectiveness of any sediment and erosion control measures selected to control the quality of storm water discharges from the clearing, grading, and excavation activities.

c. Location of inspections. Inspections shall include all areas of the site disturbed by clearing, grading, and excavation activities and areas used for storage of materials that are exposed to precipitation. Sedimentation and erosion control measures identified in the SWPPP shall be observed to ensure proper operation. Discharge locations shall be inspected to ascertain whether erosion control measures are effective in preventing significant impacts to state waters, where accessible. Where discharge locations are inaccessible, nearby downstream locations shall be inspected to the extent that such inspections are practicable. Locations where vehicles enter or exit the site shall be inspected for evidence of off-site sediment tracking.

d. Inspection reports. For each inspection required above, an inspection report shall be completed. At a minimum, the inspection report shall include:

(1) The inspection date;

(2) Names, titles, and qualifications of personnel making the inspection;

(3) Weather information for the period since the last inspection (or note if it is the first inspection) including a best estimate of the beginning of each storm event, duration of each storm event, approximate amount of rainfall for each storm event (in inches), and whether any discharges occurred;

(4) Weather information and a description of any discharges occurring at the time of the inspection;

(5) Location(s) of discharges of sediment or other pollutants from the site;

(6) Location(s) of BMPs that need to be maintained;

(7) Location(s) of BMPs that failed to operate as designed or proved inadequate for a particular location;

(8) Location(s) where additional BMPs are needed that did not exist at the time of inspection; and

(9) Corrective action(s) required, including any changes to the SWPPP necessary and implementation dates.

A record of each inspection and of any actions taken in accordance with this section shall be retained as part of the SWPPP for at least three years from the date that permit coverage expires or is terminated. The inspection reports shall identify any incidents of noncompliance with the permit conditions. Where a report does not identify any incidents of noncompliance, the report shall contain a certification that the clearing, grading, and excavation activities are in compliance with the SWPPP and this permit. The report shall be signed in accordance with Part II K of the permit.

3. Maintenance of controls for clearing, grading, and excavation activities.

a. Maintenance of BMPs. All erosion and sediment control measures and other protective measures identified in the SWPPP shall be maintained in effective operating condition. If site inspections required by subdivision 2 of this subsection identify BMPs that are not operating effectively, maintenance shall be performed as soon as possible and before the next storm event whenever practicable to maintain the continued effectiveness of storm water controls.

b. Modification of BMPs. Existing BMPs need to be modified or, if additional BMPs are necessary for any reason, implementation shall be completed before the next storm event whenever practicable. If implementation before the next storm event is impracticable, the situation shall be documented in the SWPPP and alternative BMPs shall be implemented as soon as possible.

c. Maintenance of sediment traps and ponds. Sediment from sediment traps or sedimentation ponds shall be removed when design capacity has been reduced by 50%.

4. Requirements for cessation of clearing, grading, and excavation activities.

a. Inspections and maintenance. Inspections and maintenance of BMPs associated with clearing, grading, and excavation activities being conducted as part of the exploration and construction phase of a mining operation shall continue until final stabilization has been achieved on all portions of the disturbed area.

b. Final stabilization. Stabilization measures shall be initiated immediately in portions of the site where development activities have permanently ceased, but in no case more than 14 days after the construction activity in that portion of the site has permanently ceased. In arid, semiarid, and drought-stricken areas where initiating perennial vegetative stabilization measures is not possible within 14 days after construction activity has temporarily or permanently ceased, final vegetative stabilization measures shall be initiated as soon as possible. Until final stabilization is achieved temporary stabilization measures, such as blankets and tackifiers, shall be used.

E. F. Storm water pollution prevention plan requirements. In addition to the requirements of Part III, the plan shall include, at a minimum, the following items.

1. SWPPP requirements for active, inactive, and temporarily inactive metal mining facilities, and sites undergoing reclamation.

The plan should shall consider the recovery of deicing/anti-icing materials when these materials are applied during nonprecipitation events (e.g., covering storm sewer inlets, using booms, installing absorptive interceptors in the drains, etc.) to prevent these materials from later becoming a source of storm water contamination. Used deicing fluid should shall be recycled whenever possible.

d. Routine facility inspections. The inspection frequency shall be specified in the plan. At a minimum, inspections shall be conducted once per month during deicing/anti-icing season (e.g., October through April for most airports).
