Agency Contact: Allan Brockenbrough, Department of Environmental Quality, 1111 East Main Street, Suite 1400, P.O. Box 1105, Richmond, VA 23218, telephone (804) 836-2321, or email allan.brockenbrough@deq.virginia.gov.

Background: Virginia Pollutant Discharge Elimination System (VPDES) General Permit Regulation for Concrete Products Facilities (9VAC25-193) specifies requirements for concrete products facilities to discharge process wastewater and industrial stormwater to protect water quality. The regulation must be updated to reissue the permit for the next five-year term. This regulatory action is proposed to amend and reissue the existing general permit, which expires on December 31, 2023.

Summary:

Substantive amendments include (i) adding a new definition for "corrective action"; (ii) clarifying that consistency with a total maximum daily load (TMDL) is based on an applicable TMDL that is approved prior to the term of the general permit; (iii) clarifying registration questions; (iv) adding electronic submission registration requirements for reports when these are made available by the department; and (v) in the permit requirements, clarifying dust suppression allowances and updating TMDL requirements. Additionally, updates to the stormwater management requirements conform the requirements with the VPDES General Permit Regulation for Discharges of Stormwater Associated with Industrial Activity (9VAC25-151), including adding a section on corrective actions. Clarifying changes to the proposed regulation have been made in response to feedback on the regulation by U.S. Environmental Protection Agency and include moving the definition of the acronym for total petroleum hydrocarbons, removing "discharge limitations" from the column heading for a table, and revising a table footnote.

9VAC25-193-10. Definitions.

The words and terms used in this chapter shall have the meanings defined in § 62.1-44.2 et seq. of the Code of Virginia (State Water Control Law) and 9VAC25-31 (VPDES Permit Regulation), unless the context clearly indicates otherwise, except that for the purposes of this chapter:

"Best management practices" or "BMPs" means schedules of activities, practices and prohibitions of practices, structures, vegetation, maintenance procedures, and other management practices to prevent or reduce the discharge of pollutants to surface waters. BMPs also include treatment requirements, operating procedures, and practices to control plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.

"Board" means the State Water Control Board. When used outside the context of the promulgation of regulations, including regulations to establish general permits, "board" means the Department of Environmental Quality.

"Corrective action" means any action to (i) repair, modify, or replace any stormwater control used at the facility; (ii) clean up and properly dispose of spills, releases, or other deposits at the facility; or (iii) return to compliance with permit requirements.

"Department" or "DEQ" means the [ Virginia ] Department of Environmental Quality.

"Industrial activity" means facilities or those portions of a facility where the primary purpose is classified as:

1. North American Industry Classification System (NAICS) Code 327331 - Concrete Block and Brick Manufacturing, (Executive Office of the President, Office of Management and Budget, United States, 2017) and Standard Industrial Classification (SIC) Code 3271 - Concrete Block and Brick (Office of Management and Budget (OMB) SIC Manual, 1987);

GENERAL PERMIT FOR CONCRETE PRODUCTS FACILITIES 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 concrete products facilities are authorized to discharge to surface waters within the boundaries of the Commonwealth of Virginia, except those specifically named in board regulations that prohibit such discharges.

The authorized discharge shall be in accordance with the information submitted with the registration statement, this cover page, Part I-Effluent Limitations, Monitoring Requirements, and Special Conditions, Part II-Stormwater Management, and Part III-Conditions Applicable to All VPDES Permits, as set forth in this permit.

Part I

Effluent Limitations, Monitoring Requirements, Special Conditions.

A. Effluent limitations and monitoring requirements.

1. Process wastewater. During the period beginning with the permittee's coverage under this general permit and lasting until the permit's expiration date, the permittee is authorized to discharge process wastewater that may contain input from vehicle wash water, or vehicle or equipment degreasing activities, and may be commingled with stormwater associated with industrial activity, or both. Samples taken in compliance with the monitoring requirements specified below in the table in Part I A 1 shall be taken at outfalls:

Such discharges shall be limited and monitored by the permittee as specified below as follows:

EFFLUENT CHARACTERISTICS	DISCHARGE LIMITATIONS			MONITORING REQUIREMENTS
	Average	Maximum	Minimum	Frequency (3)	Sample Type
Flow (MGD)	NL	NL	NA	1/3 Months	Estimate
Total Suspended Solids (mg/l)	30	60	NA	1/3 Months	Grab
pH (standard units)	NA	9.0(1)	6.0(1)	1/3 Months	Grab
Total Petroleum Hydrocarbons(2) (mg/l)	NA	15	NA	1/3 Months	Grab
NL = No limitation, monitoring required NA = Not applicable (1)Where the Water Quality Standards (9VAC25-260) establish alternate standards for pH in the waters receiving the discharge, those standards shall be the maximum and minimum effluent limitations. (2)Total Petroleum Hydrocarbons [ (TPH) ] limitation and monitoring are only required where a discharge contains process wastewater generated from the vehicle or equipment degreasing activities. [ Total Petroleum Hydrocarbons TPH ] shall be analyzed using EPA SW-846 Method 8015 B (1996), 8015C (2000), 8015C (2007), 8015 D (2003) for diesel range organics or EPA 40 CFR Part 136. (3)1/3 months means one sample collected per calendar quarter with reports due to the DEQ regional office no later than the 10th day of April, July, October, and January.

2. Stormwater associated with industrial activity from concrete products facilities. During the period beginning with the permittee's coverage under this general permit and lasting until the permit's expiration date, the permittee is authorized to discharge stormwater associated with industrial activity that does not combine with other process wastewaters prior to discharge. Samples taken in compliance with the monitoring requirements specified below in the table in Part I A 2 shall be taken at outfalls:

Such discharges shall be limited and monitored by the permittee as specified below as follows:

EFFLUENT CHARACTERISTICS	[ DISCHARGE LIMITATIONS ] BENCHMARK MONITORING		MONITORING REQUIREMENTS(3), (5)
	Maximum	Minimum	Frequency(4)	Sample Type
Flow (MG)	NL	NA	1/Year	Estimate(1)
Total Suspended Solids (mg/l)	[ NL 100 ](2)	NA	1/Year	Grab(2)
pH (standard units)	[ NL 9.0 ](2)	[ NL 6.0 ](2)	1/Year	Grab(2)
NL = No limitation, monitoring required NA = Not applicable (1)Estimate of the total volume of the discharge during the storm event in accordance with the operation and maintenance manual. (2) If the benchmark monitoring for total suspended solids (TSS) exceeds 100 mg/l maximum or the pH falls outside of the range of 6.0-9.0 standard units, the permittee shall evaluate the overall effectiveness of the stormwater pollution prevention plan (SWPPP) in controlling the discharge of pollutants to receiving waters [ or if corrective actions are needed (Part II A 4) ]. 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. (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 DMR due to the DEQ regional office no later than the 10th day of January of each year. (5)Quarterly visual monitoring shall be performed and recorded in accordance with Part II [ C A 1 ].

B. Special conditions.

1. There shall be no discharge of floating solids or visible foam in other than trace amounts. There shall be no solids deposition or oil sheen from petroleum products in surface water as a result of the industrial activity in the vicinity of the outfall.

2. Except as expressly authorized by this permit, no product, materials, industrial wastes, or other wastes resulting from the purchase, sale, mining, extraction, transport, preparation, or storage of raw or intermediate materials, final product, byproduct, or wastes shall be handled, disposed of, or stored so as to permit a discharge of such product, materials, industrial wastes, or other wastes to surface waters.

3. Vehicles and equipment utilized during the industrial activity on a site must be operated and maintained in such a manner as to minimize the potential or actual point source pollution of surface waters. Fuels, lubricants, coolants, and hydraulic fluids, or any other petroleum products, shall not be disposed of by discharging on the ground or into surface waters. Spent fluids shall be disposed of in a manner so as not to enter the surface or ground waters of the state and in accordance with the applicable state and federal disposal regulations. Any spilled fluids shall be cleaned up and disposed of in a manner so as not to allow their entry into the surface or ground waters of the state.

4. All washdown and washout of trucks, mixers, transport buckets, forms, or other equipment shall be conducted within designated washdown and washout areas. All washdown and washout water shall be collected for recycle or collected and treated to meet the limits in Part I A prior to discharge to the receiving stream.

5. Any waste concrete and any dredged solids from the settling basins shall be managed within a designated area, and any wastewaters, including stormwater generated from these activities, shall be collected for recycle or treated prior to discharge.

6. Wastewater should be reused or recycled whenever feasible.

7. No sewage discharges to surface waters are permitted under this general permit.

8. Operation and maintenance (O&M) manual.

a. Within 180 days after the date of coverage under this general permit, the permittee shall develop or review and update, as appropriate, an O&M manual for the permitted facility. The O&M manual shall include procedures and practices for the mitigation of pollutant discharges for the protection of state waters from the facility's operations and to ensure compliance with the requirements of the permit. The manual shall address, at a minimum:

(1) O&M practices for the process wastewater treatment units, if applicable, and chemical and material storage areas;

(2) Methods for estimating process wastewater flows, if applicable;

(3) Management and disposal procedures of process wastewater solids, if applicable;

(4) Temporary and long-term facility closure plans that shall include (i) treatment, removal, and final disposition of residual wastewater, if applicable, contaminated stormwater held at the facility, and solids; (ii) fate of structures; (iii) a removal plan for all exposed industrial materials; and (iv) description of the stabilization of land in which they were stored or placed;

(5) Testing requirements and procedures;

(6) Recordkeeping and reporting requirements; and

(7) Duties and roles of responsible officials.

b. The permittee shall operate the treatment works in accordance with the O&M manual. The O&M manual shall be reviewed and updated at least annually and shall be signed and certified in accordance with Part III K of this permit. The O&M manual shall be made available for review by department personnel upon request.

c. For facilities that do not operate process wastewater treatment units, O&M requirements included in Part I B 8 a (4) through 8 a (7) shall be included in either the O&M manual or the SWPPP stormwater pollution prevention plan.

9. If the concrete products facility discharges through a municipal separate storm sewer system to surface waters, the permittee shall notify the owner of the municipal separate storm sewer system of the existence of the discharge and include that notification with the registration statement. The notification shall include the following information: the name of the facility, a contact person and contact information (telephone and email), the location of the discharge, the nature of the discharge, and the facility's VPDES general permit number.

10. The permittee shall ensure that all process wastewater basins and lagoons maintain a minimum freeboard of one foot at all times except during a 72-hour transition period after a measurable rainfall event that results in a discharge from the site. During the 72-hour transition period, no discharge from the basins and lagoons shall occur unless it is in accordance with this permit. Within 72 hours after a measurable rainfall event that results in a discharge from the site, the freeboard in all basins and lagoons shall be returned to the minimum freeboard of one foot. Where basins are operated in a series mode of operation, the one-foot freeboard requirement for the upper basins may be waived provided the final basin will maintain the freeboard requirements of this special condition. A description of how the permittee will manage the facility to adhere to one foot of freeboard shall be included in the O&M manual required in Part I B 8 a (1). Should the one-foot freeboard not be restored by the end of the 72-hour transition period, the permittee shall take measures to correct the problem before the next rain event. In addition, the permittee shall immediately begin to monitor and document the freeboard on a daily basis until the freeboard is returned to the minimum of one foot.

11. Process wastewater, commingled process wastewater, and stormwater or stormwater treatment units designed to operate as "no discharge" shall have no discharge of wastewater or pollutants except in storm events greater than a 25-year, 24-hour storm event. In the event of such a discharge, the permittee shall report an unusual or extraordinary discharge per Part III H of this permit. No sampling or DMR is required for these discharges as they are considered to be discharging in emergency discharge conditions. All other conditions in Part I B, Part II, and Part III apply. Any other discharge from this type of system is prohibited and shall be reported as an unauthorized discharge per Part III G of this permit. The operation of these systems shall not contravene the Water Quality Standards (9VAC25-260), as adopted and amended by the board, or any provision of the State Water Control Law.

12. The permittee shall notify the department as soon as he the permittee knows or has reason to believe:

a. That any activity has occurred or will occur that would result in the discharge, on a routine or frequent basis, of any toxic pollutant that is not limited in this permit if that discharge will exceed the highest of the following notification levels:

(1) One hundred micrograms per liter (100 µg/l) of the toxic pollutant;

(2) Two hundred micrograms per liter (200 µg/l) for acrolein and acrylonitrile; five hundred micrograms per liter (500 µg/l) for 2,4-dinitrophenol and for 2-methyl-4,6-dinitrophenol; and one milligram per liter (1 mg/l) for antimony;

(3) Five times the maximum concentration value reported for that pollutant in the permit application; or

(4) The level established by the board department in accordance with 9VAC25-31-220 F.

b. That any activity has occurred or will occur which that would result in any discharge, on a nonroutine or infrequent basis, of a toxic pollutant which that is not limited in this permit if that discharge will exceed the highest of the following notification levels:

(1) Five hundred micrograms per liter (500 µg/l) of the toxic pollutant;

(2) One milligram per liter (1 mg/l) for antimony;

(3) Ten times the maximum concentration value reported for that pollutant in the permit application; or

(4) The level established by the board department in accordance with 9VAC25-31-220 F.

13. All settling basins used for treatment and control of process wastewater or process wastewater commingled with stormwater that were constructed on or after February 2, 1998, shall be lined with concrete or any other impermeable materials. Regardless of date of construction, all settling basins used for treatment and control of process wastewater or process wastewater commingled with stormwater that are expanded or dewatered for major structural repairs shall be lined with concrete or any other impermeable materials.

14. Settled wastewater may be used on site for the purposes of dust suppression or for spraying stockpiles. Dust suppression shall be carried out as a best management practice but not as a wastewater disposal method provided that ponding or direct run-off from the site does not occur during or immediately following its application. Water used for dust suppression may be discharged provided that it has been filtered, settled, or similarly treated. Settled wastewater may be used on site for the purpose of dust suppression or for spraying stockpiles. Dust suppression shall not occur during a "measurable" rain event (a storm event that results in an actual discharge from the site).

15. Compliance reporting under Part I A.

a. The quantification levels (QL) shall be less than or equal to the following concentrations:

Effluent Characteristic	Quantification Level
TSS	1.0 mg/l
TPH	5.0 mg/l

The QL is defined as the lowest concentration used to calibrate a measurement system in accordance with the procedures published for the test method.

b. Reporting.

(1) Monthly average. Compliance with the monthly average limitations or reporting requirements for the parameters listed in Part I A shall be determined as follows: All concentration data below the QL listed in [ subdivision Part I B ] 15 a [ of this subsection ] shall be treated as zero. All concentration data equal to or above the QL listed shall be treated as it is reported. An arithmetic average shall be calculated using all reported data, including the defined zeros, for the month. This arithmetic average shall be reported on the DMR as calculated. If all data are below the QL then the average shall be reported as "<QL." If reporting for quantity is required on the DMR and the calculated concentration is [ <QL less than QL ] then report "<QL" for the quantity, otherwise use the calculated concentration.

(2) Daily maximum. Compliance with the daily maximum limitations or reporting requirements for the parameters listed in Part I A shall be determined as follows: All concentration data below the QL listed in [ subdivision Part I B ] 15 a [ of this subsection ] shall be treated as zero. All concentration data equal to or above the QL shall be treated as reported. An arithmetic average of the values shall be calculated using all reported data, including the defined zeros, collected for each day during the reporting month. The maximum value of these daily averages thus determined shall be reported on the DMR as the daily maximum. If all data are below the QL then the average shall be reported as "<QL." If reporting for quantity is required on the DMR and the calculated concentration is [ <QL less than QL ] then report "<QL" for the quantity, otherwise use the calculated concentration.

(3) Any single datum required shall be reported as "<QL" if it is less than the QL listed in [ subdivision Part I B ] 15 a [ of this subsection ]. Otherwise the numerical value shall be reported. The QL must be less than or equal to the QL in [ subdivision Part I B ] 15 a [ of this subsection ].

(4) The permittee shall report at least two significant digits for a given parameter. Regardless of the rounding convention used (i.e., five always rounding up or to the nearest even number) by the permittee, the permittee shall use the convention consistently and shall ensure that consulting laboratories employed by the permittee use the same convention.

16. Discharges to waters with an approved total maximum daily load (TMDL). Owners of facilities that are a source of the specified pollutant of concern to waters where an approved TMDL has been established a TMDL has been approved prior to the term of this permit shall implement measures and controls 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. If the TMDL establishes a numeric wasteload allocation that applies to discharges from the facility, the owner shall perform monitoring for the pollutant of concern in accordance with the monitoring frequencies in Part I A and implement measures necessary to meet that allocation. At permit reissuance, the permittee shall submit a demonstration with the registration statement to show the wasteload allocation is being met.

17. Adding or deleting outfalls. The permittee may add new or delete existing outfalls at the facility as necessary and appropriate. The permittee shall update the O&M manual and stormwater pollution prevention plan (SWPPP) and notify the department of all outfall changes within 60 days of the change. The permittee shall submit an updated registration statement including an updated SWPPP site map.

Part II
Stormwater Management.

A. Monitoring instructions requirements.

1. Quarterly visual monitoring. The permittee shall perform and document visual monitoring of stormwater discharges associated with industrial activity from each outfall, except discharges waived in Part II A 1 d. The visual monitoring must be made during 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.

a. Samples shall be collected in accordance with Part II A 3. No analytical tests are required to be performed on the samples.

b. Samples will be in a clean, colorless glass or plastic container and examined in a well-lit area.

c. The examination shall observe color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution.

d. If no storm event resulted in discharge 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.

e. When adverse weather conditions prevent the collection of samples, a substitute sample may be taken during a storm event that results in a discharge from the site 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. Narrative documentation of conditions necessitating the use of the waiver shall be kept with the stormwater pollution prevention plan (SWPPP).

f. Visual monitoring documentation shall be maintained on site with the SWPPP and shall include:

(1) Outfall location;

(2) Monitoring date and time;

(3) Monitoring personnel;

(4) Nature of the discharge (i.e., runoff or snow melt);

(5) Visual quality of the stormwater discharge, including observations of color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution; and

(6) Probable sources of any observed stormwater contamination.

2. Benchmark monitoring. If the benchmark monitoring for total suspended solids exceeds 100 mg/l maximum or the pH falls outside of the range of 6.0 to 9.0 standard units, the permittee shall evaluate the overall effectiveness of the SWPPP in controlling the discharge of pollutants to receiving waters [ or if corrective actions (Part II A 4) are needed ]. 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 a routine facility inspection.

3. Monitoring instructions.

1. a. 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. b. 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 discharge is at least 72 hours. The 72-hour storm interval is waived if the permittee is able to document with the 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 three hours of discharge provided that the permittee explains with the SWPPP why a grab sample during the first 30 minutes was impractical.

3. c. 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 DMR the following information:

a. (1) Date and duration (in hours) of the storm events sampled;

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

c. Duration (3) Interval between the storm event sampled and the end of the previous measurable storm event that resulted in a discharge from the site.

4. Corrective actions. The permittee shall review the SWPPP and modify it as necessary to address any deficiencies noted in Part II A 4 a and 4 b. Revisions to the SWPPP shall be completed within 60 days following the discovery of the deficiency. When control measures need to be modified or added, implementation shall 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. In cases where construction is necessary to implement control measures, the permittee shall include a schedule in the SWPPP that provides for the completion of the control measures as expeditiously as practicable, but no later than three years after the deficiency is discovered. Where a construction compliance schedule is included in the SWPPP, the SWPPP shall include appropriate nonstructural and temporary controls to be implemented in the affected portion of the facility prior to completion of the permanent control measure. The amount of time taken to modify a control measure or implement additional control measures shall be documented in the SWPPP. The permittee shall take corrective action whenever:

a. Benchmark monitoring; routine facility inspections; inspections by local, state, or federal officials; or any other process, observation, or event result in a determination that modifications to the stormwater control measures are necessary to meet the permit requirements; or

b. The department determines or the permittee becomes aware that the stormwater control measures are not stringent enough for the discharge to meet applicable water quality standards.

Any corrective actions taken shall be documented and retained with the SWPPP.

B. Representative outfalls - substantially identical outfalls. If a facility has two or more exclusively stormwater outfalls that discharge substantially identical effluents, based on similarities of the industrial activities, significant materials, size of drainage areas, and stormwater management practices occurring within the drainage areas of the outfalls, frequency of discharges, and stormwater management practices occurring within the drainage areas of the outfalls, the permittee may monitor the effluent stormwater of just one of the outfalls and report that the observations also apply to the substantially identical outfall. Representative outfalls must be identified in the registration statement submitted for coverage under this permit. Substantially identical outfall monitoring can apply to quarterly visual and benchmark monitoring. The permittee must include the following information in the SWPPP:

1. The locations of the outfalls;

2. Why An evaluation, including available monitoring data, indicating the outfalls are expected to discharge substantially identical effluents, including evaluation of monitoring data where available;

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. Quarterly visual monitoring of stormwater quality. The permittee shall perform and document visual monitoring of stormwater discharges associated with industrial activity from each outfall, except discharges waived in Part II C 4 . The visual monitoring must be made during 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. Samples will be in a clean, colorless glass or plastic container and examined in a well-lit area.

2. Samples will be collected within the first 30 minutes (or as soon thereafter as practical, but not to exceed three hours, provided that the permittee explains in the SWPPP why an examination during the first 30 minutes was impractical) of when the runoff or snowmelt begins discharging. All such samples shall be collected from the discharge resulting from a storm event that 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 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.

3. The examination shall observe color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution.

4. If no qualifying storm event resulted in discharge from the facility during a monitoring period, or adverse weather conditions create dangerous conditions for personnel during each measurable storm event during a monitoring period, visual monitoring is exempted provided this is documented in the SWPPP.

5. Visual monitoring reports shall be maintained onsite with the SWPPP. The report shall include the outfall location, the monitoring date and time, monitoring personnel, the nature of the discharge (i.e., runoff or snow melt), visual quality of the stormwater discharge (including observations of color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution), and probable sources of any observed stormwater contamination.

6. Whenever the visual monitoring shows obvious indicators of stormwater pollution, the SWPPP and stormwater controls shall be updated per Part II F.

D. Allowable nonstormwater discharges. The following nonstormwater discharges are authorized by this permit.

1. Discharges from emergency firefighting activities;

2. Fire hydrant flushings;

3. Potable water including water line flushings;

4. Uncontaminated condensate from air conditioners, coolers, and other compressors and from the outside storage of refrigerated gases or liquids;

5. Irrigation drainage;

6. Landscape watering provided all pesticides, herbicides, and fertilizer have been applied in accordance with the approved labeling;

7. Pavement wash waters where no detergents or hazardous cleaning products are used and no spills or leaks of toxic or hazardous materials have occurred (unless all spilled material has been removed). Pavement wash waters shall be managed to prevent the discharge of pollutants;

8. Routine external building washdown that does not use detergents or hazardous cleaning products;

9. Uncontaminated ground water or spring water;

10. Foundation or footing drains where flows are not contaminated with process materials; and

11. Incidental windblown mist from cooling towers that collects on rooftops or adjacent portions of the facility, but not intentional discharges from the cooling tower (e.g., "piped" cooling tower blowdown or drains).

E. C. Releases of hazardous substances or oil in excess of reportable quantities. The discharge of hazardous substances or oil in the stormwater discharges from this facility shall be prevented or minimized in accordance with the SWPPP for the facility. This permit does not authorize the discharge of hazardous substances or oil resulting from an onsite on-site spill. This permit does not relieve the permittee of the reporting requirements of 40 CFR Part 110, 40 CFR Part 117, and 40 CFR Part 302 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, 40 CFR Part 117, or 40 CFR Part 302 occurs during a 24-hour period:

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

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

3. The SWPPP required by this permit shall be reviewed to identify measures to prevent the reoccurrence of such releases and to respond to such releases, and the plan must be modified where appropriate.

F. D. Stormwater pollution prevention plans (SWPPP). A An SWPPP shall be developed and implemented for the facility covered by this permit. The SWPPP shall include best management practices (BMPs) that are reasonable, economically practicable, and appropriate in light of current industry practices. The BMPs shall be selected, designed, installed, implemented, and maintained in accordance with good engineering practices to eliminate or reduce the pollutants in all stormwater discharges from the facility. The SWPPP shall also include any control measures necessary for the stormwater discharges to meet applicable water quality standards. The SWPPP is intended to document the selection, design, and installation of control measures, including BMPs, to minimize the pollutants in all stormwater discharges from the facility and to meet applicable effluent limitations and water quality standards.

The SWPPP requirements of this general permit may be fulfilled, in part, by incorporating by reference other plans or documents, such as an erosion and sediment control plan, a spill prevention control and countermeasure (SPCC) plan developed for the facility under § 311 of the Clean Water Act, or BMP programs otherwise required for the facility provided that the incorporated plan meets or exceeds the SWPPP requirements of Part II F 6 (Contents of SWPPP) D 2. All plans incorporated by reference into the SWPPP become enforceable under this permit.

All reasonable steps shall be taken to control or address the quality of discharges from the site that may not originate at the facility If applicable, regulated stormwater discharges from the facility include stormwater run-on that commingles with stormwater discharges associated with industrial activity at the facility. The SWPPP shall describe the type, location, and implementation of all BMPs control measures for each area where industrial materials or activities are exposed to stormwater. Selection of control measures shall take into consideration:

(a) That preventing stormwater from coming into contact with polluting materials is generally more effective and less costly than trying to remove pollutants from stormwater;

(b) Control measures generally must be used in combination with each other for most effective water quality protection;

(c) Assessing the type and quantity of pollutants, including their potential to impact receiving water quality, is critical to designing effective control measures;

(d) That minimizing impervious areas at the facility can reduce runoff and improve groundwater recharge and stream base flows in local streams; however, care must be taken to avoid groundwater contamination;

(e) Flow attenuation by use of open vegetated swales and natural depressions can reduce instream impacts of erosive flows;

(f) Conservation or restoration of riparian buffers will help protect streams from stormwater runoff and improve water quality; and

(g) Treatment interceptors (e.g., swirl separators and sand filters) may be appropriate in some instances to minimize the discharge of pollutants.

(2) Good housekeeping measures. Good housekeeping requires the clean and orderly maintenance of areas that may contribute pollutants to stormwater discharges. The permittee shall keep clean all exposed areas of the facility that are potential sources of pollutants in stormwater. Particular attention should be paid to areas where raw materials are stockpiled, material handling areas, storage areas, liquid storage tanks, vehicle fueling and maintenance areas, and loading or unloading areas. The SWPPP shall describe procedures performed to prevent The permittee shall perform the following good housekeeping measures to minimize pollutant discharges:

(a) Include a schedule for regular pickup and disposal of waste materials, along with routine inspections for leaks and conditions of drums, tanks, and containers;

(b) Sweep or vacuum as feasible;

(c) Store materials in containers constructed of appropriate materials;

(d) Manage all waste containers to prevent a discharge of pollutants;

(e) Minimize the potential for waste, garbage, and floatable debris to be discharged by keeping areas exposed to stormwater free of such materials or by intercepting such materials prior to discharge; and

(f) Prevent or minimize the discharge of: spilled cement, aggregate (, including sand and gravel), kiln dust, fly ash, settled dust, or other significant material in stormwater from paved portions of the site that are exposed to stormwater. Sweep or vacuum paved surfaces of the site that are exposed to stormwater at regular intervals or use other equivalent measures to minimize the potential discharge of these materials in stormwater. Indicate in the SWPPP the frequency of sweeping, vacuuming, or other equivalent measures (e.g., wash down the area and collect or treat and properly dispose of the washdown water). Determine the frequency based on the amount of industrial activity occurring in the area and the frequency of precipitation, but sweeping, vacuuming, or other equivalent measures shall be performed at least once a week in areas where cement, aggregate, kiln dust, fly ash, or settled dust are being handled or processed. Prevent the exposure of fine granular solids (, including cement, fly ash, and kiln dust), to stormwater, where practicable, by storing these materials in enclosed silos, hoppers, or buildings or under other covering. The generation of dust and off-site vehicle tracking of raw, final, or waste materials, or sediments shall be minimized.

(3) Preventive maintenance. A preventive maintenance program shall involve regular inspection, testing, maintenance, and repairing of all industrial equipment and systems to avoid breakdowns or failures that could result in leaks, spills, and other releases. This program is in addition to the specific BMP maintenance required under Part II F 7 (Maintenance of BMPs) E.

(4) Spill prevention and response procedures. The SWPPP shall describe the procedures that will be followed for preventing and responding to spills and leaks., including:

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

(b) Response procedures shall include (i), including notification of appropriate facility personnel, emergency agencies, and regulatory agencies and (ii) procedures for stopping, containing, and cleaning up spills. Measures for cleaning up hazardous material spills or leaks shall be consistent with applicable RCRA Resource Conservation and Recovery Act regulations at 40 CFR Part 264 and 40 CFR Part 265. 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) Procedures for plainly labeling containers (e.g., "used oil," "spent solvents," "fertilizers and pesticides," etc.) that could be susceptible to spillage or leakage to encourage proper handling and facilitate rapid response if spills or leaks occur; and

(d) 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.

(5) Routine facility inspections.

(a) During normal facility operating hours inspections of areas of the facility covered by the requirements in this permit must be conducted and shall include observations of the following:

(i) Areas where industrial materials or activities are exposed to stormwater, including material handling areas, above ground storage tanks, hoppers or silos, dust collection or containment systems, and truck wash down or equipment cleaning areas;

(ii) Discharge points; and

(iii) Best management practices.

(b) Inspections shall be conducted at least quarterly. At least once each calendar year, the routine facility inspection should be conducted during a period when a stormwater discharge is occurring.

(c) Inspections shall be performed by personnel who possess the knowledge and skills to assess conditions and activities that could impact stormwater quality at the facility and who can also evaluate the effectiveness of BMPs. At least one member of the stormwater pollution prevention team shall participate.

(d) Routine facility inspections shall be documented and maintained with the SWPPP. Document all findings including:

(i) Inspection date;

(ii) Names of the inspectors; and

(iii) Observations of any discharges; the physical condition of and around all outfalls (e.g., concrete product in the stream or turbidity); leaks or spills from industrial equipment, drums, tanks or other containers; offsite tracking of industrial materials or sediment; any additional best management practices that need to be repaired, maintained, or added; and any incidents of noncompliance.

(e) A set of tracking or followup procedures shall be used to ensure that appropriate actions are taken in response to the inspections. Records of inspections shall be maintained with the SWPPP. Any deficiencies in the implementation of the SWPPP that are found shall be corrected as soon as practicable, but not later than within 60 days of the inspection, unless permission for a later date is granted in writing by the director.

a. The authorization is made in writing by a person described in Part III K 1;

b. The authorization specifies either an individual or a position having responsibility for the overall operation of the regulated facility or activity such as the position of plant manager, operator of a well or a well field, superintendent, position of equivalent responsibility, or an individual or position having overall responsibility for environmental matters for the company. A duly authorized representative may thus be either a named individual or any individual occupying a named position; and

c. The written authorization is submitted to the department.

3. Changes to authorization. If an authorization under Part III K 2 is no longer accurate because a different individual or position has responsibility for the overall operation of the facility, a new authorization satisfying the requirements of Part III K 2 shall be submitted to the department prior to or together with any reports, or information to be signed by an authorized representative.

4. Certification. Any person signing a document under Part III K 1 or 2 shall make the following certification:

"I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations."

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 coverage termination; or denial of a permit coverage renewal registration.

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.

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 "bypass" ( in Part III U), and "upset" ( in 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) that 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 that 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 that 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 that 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 Part 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 department 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 that 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 department may approve an anticipated bypass, after considering its adverse effects, if the board department determines that it will meet the three conditions listed in Part III U 3 a.

V. Upset.

1. An upset constitutes an affirmative defense to an action brought for noncompliance with technology based 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 the director's authorized representative, including an authorized contractor acting as a representative of the administrator, upon presentation of credentials and other documents as may be required by law, to:

1. Enter upon the permittee's premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of 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 in this section shall make an inspection unreasonable during an emergency.

X. Permit actions. Permit coverage may be terminated for cause. The filing of a request by the permittee for a permit termination, or a notification of planned changes or anticipated noncompliance does not stay any permit condition.

Y. Transfer of permit coverage.

1. Permits are not transferable to any person except after notice to the department.

2. Coverage under this permit may be automatically transferred to a new permittee if:

a. The current permittee notifies the department within 30 days of the transfer of the title to the facility or property unless permission for a later date has been granted by the board department;

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

c. The board department does not notify the existing permittee and the proposed new permittee of its intent to 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.

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.
