A. Channel protection and flood protection shall be addressed in accordance with the minimum standards set out in this section, which are established pursuant to the requirements of subdivision 7 of § 10.1-603.4 of the Code of Virginia. Nothing in this section shall prohibit a local stormwater management program locality's VSMP authority from establishing a more stringent standard especially where more stringent requirements are necessary to address total maximum daily load requirements or to protect exceptional state waters. Compliance with the minimum standards set out in this section shall be deemed to satisfy the requirements of subdivision 19 of 4VAC50-30-40 (Minimum Standard 19 of the Virginia Erosion and Sediment Control Regulations).

B. Channel protection. Concentrated stormwater flow shall be released into a stormwater conveyance system and shall meet the criteria in subdivision 1, 2, or 3 of this subsection, where applicable, from the point of discharge to a point to the limits of analysis in subdivision 4 of this subsection.

1. Manmade stormwater conveyance systems. When stormwater from a development is discharged to a manmade stormwater conveyance system, following the land-disturbing activity, either:

a. The manmade stormwater conveyance system shall convey the postdevelopment peak flow rate from the two-year 24-hour storm event without causing erosion of the system. Detention of stormwater or downstream improvements may be incorporated into the approved land-disturbing activity to meet this criterion, at the discretion of the stormwater program administrative VSMP authority; or

b. The peak discharge requirements for concentrated stormwater flow to natural stormwater conveyance systems in subdivision 3 of this subsection shall be met.

2. Restored stormwater conveyance systems. When stormwater from a development is discharged to a restored stormwater conveyance system that has been restored using natural design concepts, following the land-disturbing activity, either:

a. The development shall be consistent, in combination with other stormwater runoff, with the design parameters of the restored stormwater conveyance system that is functioning in accordance with the design objectives; or

b. The peak discharge requirements for concentrated stormwater flow to natural stormwater conveyance systems in subdivision 3 of this subsection shall be met.

a. In accordance with the following methodology:

QDeveloped ≤ I.F.*(QPre-developed* RVPre-Developed)/RVDeveloped

Under no condition shall QDeveloped be greater than QPre-Developed nor shall QDeveloped be required to be less than that calculated in the equation (QForest * RVForest)/RVDeveloped; where

I.F. (Improvement Factor) equals 0.8 for sites > 1 acre or 0.9 for sites ≤ 1 acre.

QDeveloped = The allowable peak flow rate of runoff from the developed site.

RVDeveloped = The volume of runoff from the site in the developed condition.

QPre-Developed = The peak flow rate of runoff from the site in the pre-developed condition.

RVPre-Developed = The volume of runoff from the site in pre-developed condition.

QForest = The peak flow rate of runoff from the site in a forested condition.

RVForest = The volume of runoff from the site in a forested condition; or

b. In accordance with another methodology that is demonstrated by the local stormwater management program VSMP authority to achieve equivalent results and is approved by the board. 

4. Limits of analysis. Unless subdivision 3 of this subsection is utilized to show compliance with the channel protection criteria, stormwater conveyance systems shall be analyzed for compliance with channel protection criteria to a point where either:

a. Based on land area, the site's contributing drainage area is less than or equal to 1.0% of the total watershed area; or

b. Based on peak flow rate, the site's peak flow rate from the one-year 24-hour storm is less than or equal to 1.0% of the existing peak flow rate from the one-year 24-hour storm prior to the implementation of any stormwater quantity control measures.

C. Flood protection. Concentrated stormwater flow shall be released into a stormwater conveyance system and shall meet one of the following criteria as demonstrated by use of acceptable hydrologic and hydraulic methodologies:

1. Concentrated stormwater flow to stormwater conveyance systems that currently do not experience localized flooding during the 10-year 24-hour storm event: The point of discharge releases stormwater into a stormwater conveyance system that, following the land-disturbing activity, confines the postdevelopment peak flow rate from the 10-year 24-hour storm event within the stormwater conveyance system. Detention of stormwater or downstream improvements may be incorporated into the approved land-disturbing activity to meet this criterion, at the discretion of the stormwater program administrative VSMP authority.

2. Concentrated stormwater flow to stormwater conveyance systems that currently experience localized flooding during the 10-year 24-hour storm event: The point of discharge either:

a. Confines the postdevelopment peak flow rate from the 10-year 24-hour storm event within the stormwater conveyance system to avoid the localized flooding. Detention of stormwater or downstream improvements may be incorporated into the approved land-disturbing activity to meet this criterion, at the discretion of the stormwater program administrative VSMP authority; or

b. Releases a postdevelopment peak flow rate for the 10-year 24-hour storm event that is less than the predevelopment peak flow rate from the 10-year 24-hour storm event. Downstream stormwater conveyance systems do not require any additional analysis to show compliance with flood protection criteria is this option is utilized.

3. Limits of analysis. Unless subdivision 2 b of this subsection is utilized to comply with the flood protection criteria, stormwater conveyance systems shall be analyzed for compliance with flood protection criteria to a point where:

a. The site's contributing drainage area is less than or equal to 1.0% of the total watershed area draining to a point of analysis in the downstream stormwater conveyance system;

b. Based on peak flow rate, the site's peak flow rate from the 10-year 24-hour storm event is less than or equal to 1.0% of the existing peak flow rate from the 10-year 24-hour storm event prior to the implementation of any stormwater quantity control measures; or

c. The stormwater conveyance system enters a mapped floodplain or other flood-prone area, adopted by ordinance, of any locality.

D. Increased volumes of sheet flow resulting from pervious or disconnected impervious areas, or from physical spreading of concentrated flow through level spreaders, must be identified and evaluated for potential impacts on down-gradient properties or resources. Increased volumes of sheet flow that will cause or contribute to erosion, sedimentation, or flooding of down gradient properties or resources shall be diverted to a stormwater management facility or a stormwater conveyance system that conveys the runoff without causing down-gradient erosion, sedimentation, or flooding. If all runoff from the site is sheet flow and the conditions of this subsection are met, no further water quantity controls are required.

E. For purposes of computing predevelopment runoff, all pervious lands on the site shall be assumed to be in good hydrologic condition in accordance with the U.S. Department of Agriculture's Natural Resources Conservation Service (NRCS) standards, regardless of conditions existing at the time of computation. Predevelopment runoff calculations utilizing other hydrologic conditions may be utilized provided that it is demonstrated to and approved by the stormwater program administrative VSMP authority that actual site conditions warrant such considerations.

F. Predevelopment and postdevelopment runoff characteristics and site hydrology shall be verified by site inspections, topographic surveys, available soil mapping or studies, and calculations consistent with good engineering practices. Guidance provided in the Virginia Stormwater Management Handbook and by the Virginia Stormwater BMP Clearinghouse shall be considered appropriate practices.

4VAC50-60-93.1

Part II C
Technical Criteria for Regulated Land-Disturbing Activities:
Grandfathered Projects and Projects Subject to the Provisions of 4VAC50-60-47.1

4VAC50-60-93.1. Definitions.

For the purposes of Part II C only, the following words and terms have the following meanings unless the context clearly indicates otherwise:

"Adequate channel" means a channel that will convey the designated frequency storm event without overtopping the channel bank nor causing erosive damage to the channel bed or banks.

"Aquatic bench" means a 10-foot to 15-foot wide bench around the inside perimeter of a permanent pool that ranges in depth from zero to 12 inches. Vegetated with emergent plants, the bench augments pollutant removal, provides habitats, conceals trash and water level fluctuations, and enhances safety.

"Average land cover condition" means a measure of the average amount of impervious surfaces within a watershed, assumed to be 16%. Note that a locality may opt to calculate actual or a calculated watershed-specific values value for the average land cover condition based upon 4VAC50-60-110 as approved by the Chesapeake Bay Local Assistance Board prior to September 13, 2011.

"Bioretention basin" means a water quality BMP engineered to filter the water quality volume (i) through an engineered planting bed consisting of a vegetated surface layer (vegetation, mulch, ground cover), planting soil, and sand bed and (ii) into the in-situ material.

"Bioretention filter" means a bioretention basin with the addition of a sand filter collector pipe system beneath the planting bed.

"Constructed wetlands" means areas intentionally designed and created to emulate the water quality improvement function of wetlands for the primary purpose of removing pollutants from stormwater.

"Development" means a tract of land developed or to be developed as a unit under single ownership or unified control which is to be used for any business or industrial purpose or is to contain three or more residential dwelling units.

"Grassed swale" means an earthen conveyance system which is broad and shallow with erosion resistant grasses and check dams, engineered to remove pollutants from stormwater runoff by filtration through grass and infiltration into the soil.

"Infiltration facility" means a stormwater management facility that temporarily impounds runoff and discharges it via infiltration through the surrounding soil. While an infiltration facility may also be equipped with an outlet structure to discharge impounded runoff, such discharge is normally reserved for overflow and other emergency conditions. Since an infiltration facility impounds runoff only temporarily, it is normally dry during nonrainfall periods. Infiltration basin, infiltration trench, infiltration dry well, and porous pavement shall be considered infiltration facilities.

"Nonpoint source pollutant runoff load" or "pollutant discharge" means the average amount of a particular pollutant measured in pounds per year, delivered in a diffuse manner by stormwater runoff.

"Planning area" means a designated portion of the parcel on which the land development project is located. Planning areas shall be established by delineation on a master plan. Once established, planning areas shall be applied consistently for all future projects.

"Sand filter" means a contained bed of sand that acts to filter the first flush of runoff. The runoff is then collected beneath the sand bed and conveyed to an adequate discharge point or infiltrated into the in-situ soils.

"Shallow marsh" means a zone within a stormwater extended detention basin that exists from the surface of the normal pool to a depth of six to 18 inches, and has a large surface area and, therefore, requires a reliable source of baseflow, groundwater supply, or a sizeable drainage area to maintain the desired water surface elevations to support emergent vegetation.

"Stormwater detention basin" or "detention basin" means a stormwater management facility that temporarily impounds runoff and discharges it through a hydraulic outlet structure to a downstream conveyance system. While a certain amount of outflow may also occur via infiltration through the surrounding soil, such amounts are negligible when compared to the outlet structure discharge rates and are, therefore, not considered in the facility's design. Since a detention facility impounds runoff only temporarily, it is normally dry during nonrainfall periods.

"Stormwater extended detention basin" or "extended detention basin" means a stormwater management facility that temporarily impounds runoff and discharges it through a hydraulic outlet structure over a specified period of time to a downstream conveyance system for the purpose of water quality enhancement or stream channel erosion control. While a certain amount of outflow may also occur via infiltration through the surrounding soil, such amounts are negligible when compared to the outlet structure discharge rates and, therefore, are not considered in the facility's design. Since an extended detention basin impounds runoff only temporarily, it is normally dry during nonrainfall periods.

"Stormwater extended detention basin-enhanced" or "extended detention basin-enhanced" means an extended detention basin modified to increase pollutant removal by providing a shallow marsh in the lower stage of the basin.

"Stormwater retention basin" or "retention basin" means a stormwater management facility that includes a permanent impoundment, or normal pool of water, for the purpose of enhancing water quality and, therefore, is normally wet even during nonrainfall periods. Storm runoff inflows may be temporarily stored above this permanent impoundment for the purpose of reducing flooding or stream channel erosion.

"Stormwater retention basin I" or "retention basin I" means a retention basin with the volume of the permanent pool equal to three times the water quality volume.

"Stormwater retention basin II" or "retention basin II" means a retention basin with the volume of the permanent pool equal to four times the water quality volume.

"Stormwater retention basin III" or "retention basin III" means a retention basin with the volume of the permanent pool equal to four times the water quality volume with the addition of an aquatic bench.

"Vegetated filter strip" means a densely vegetated section of land engineered to accept runoff as overland sheet flow from upstream development. It shall adopt any natural vegetated form, from grassy meadow to small forest. The vegetative cover facilitates pollutant removal through filtration, sediment deposition, infiltration, and absorption, and is dedicated for that purpose.

"Water quality volume" means the volume equal to the first 1/2 inch of runoff multiplied by the impervious surface of the land development project.

4VAC50-60-95

4VAC50-60-95. General.

A. Determination of flooding and channel erosion impacts to receiving streams due to land-disturbing activities shall be measured at each point of discharge from the land disturbance and such determination shall include any runoff from the balance of the watershed that also contributes to that point of discharge.

B. The specified design storms shall be defined as either a 24-hour storm using the rainfall distribution recommended by the U.S. Department of Agriculture's Natural Resources Conservation Service (NRCS) when using NRCS methods or as the storm of critical duration that produces the greatest required storage volume at the site when using a design method such as the Modified Rational Method.

C. For purposes of computing runoff, all pervious lands in the site shall be assumed prior to development to be in good condition (if the lands are pastures, lawns, or parks), with good cover (if the lands are woods), or with conservation treatment (if the lands are cultivated); regardless of conditions existing at the time of computation.

Hydrologic parameters shall reflect the ultimate land disturbance and shall be used in all engineering calculations.

I. All stormwater management facilities shall have an inspection and maintenance plan that identifies the owner and the responsible party for carrying out the inspection and maintenance plan.

J. Construction of stormwater management impoundment structures within a Federal Emergency Management Agency (FEMA) designated 100-year floodplain shall be avoided to the extent possible. When this is unavoidable, all stormwater management facility construction shall be in compliance with all applicable regulations under the National Flood Insurance Program, 44 CFR Part 59.

K. Natural channel characteristics shall be preserved to the maximum extent practicable.

L. Land-disturbing activities shall comply with the Virginia Erosion and Sediment Control Law (§ 10.1-560 et seq. of the Code of Virginia) and attendant regulations.

M. Flood control and stormwater management facilities that drain or treat water from multiple development projects or from a significant portion of a watershed may be allowed in resource protection areas defined in the Chesapeake Bay Preservation Act provided such facilities are allowed and constructed in accordance with the Stormwater Management Act (§ 10.1-603.2 et seq. of the Code of Virginia) and this chapter, and provided that (i) the local government has conclusively established that the location of the facility within the resource protection area is the optimum location; (ii) the size of the facility is the minimum necessary to provide necessary flood control, stormwater treatment, or both; and (iii) the facility must be consistent with a stormwater management program comprehensive stormwater management plan developed and approved in accordance with 4VAC50-60-92 or with a VSMP that has been approved prior to July 1, 2012, by the board, the Chesapeake Bay Local Assistance Board prior to its abolishment on July 1, 2012, or the Board of Conservation and Recreation; (iv) all applicable permits for construction in state or federal waters must be obtained from the appropriate state and federal agencies, such as the U.S. Army Corps of Engineers, the Virginia Department of Conservation and Recreation, the Virginia Department of Environmental Quality, and the Virginia Marine Resources Commission; (v) approval must be received from the local government prior to construction; and (vi) routine maintenance is allowed to be performed on such facilities to assure that they continue to function as designed. It is not the intent of this subdivision to allow a best management practice that collects and treats runoff from only an individual lot or some portion of the lot to be located within a resource protection area.

4VAC50-60-96

4VAC50-60-96. Water quality.

A. Compliance with the water quality criteria may be achieved by applying the performance-based criteria or the technology-based criteria to either the site or a planning area.

B. Performance-based criteria. For land-disturbing activities, the calculated postdevelopment nonpoint source pollutant runoff load shall be compared to the calculated predevelopment load based upon the average land cover condition or the existing site condition. A BMP shall be located, designed, and maintained to achieve the target pollutant removal efficiencies specified in Table 1 of this section to effectively reduce the pollutant load to the required level based upon the following four applicable land development situations for which the performance criteria apply:

1. Situation 1 consists of land-disturbing activities where the existing percent impervious cover is less than or equal to the average land cover condition and the proposed improvements will create a total percent impervious cover that is less than the average land cover condition.

Requirement: No reduction in the after disturbance pollutant discharge is required.

2. Situation 2 consists of land-disturbing activities where the existing percent impervious cover is less than or equal to the average land cover condition and the proposed improvements will create a total percent impervious cover that is greater than the average land cover condition.

Requirement: The pollutant discharge after disturbance shall not exceed the existing pollutant discharge based on the average land cover condition.

3. Situation 3 consists of land-disturbing activities where the existing percent impervious cover is greater than the average land cover condition.

Requirement: The pollutant discharge after disturbance shall not exceed (i) the pollutant discharge based on existing conditions less 10% or (ii) the pollutant discharge based on the average land cover condition, whichever is greater.

4. Situation 4 consists of land-disturbing activities where the existing percent impervious cover is served by an existing stormwater management BMP that addresses water quality.

Requirement: The pollutant discharge after disturbance shall not exceed the existing pollutant discharge based on the existing percent impervious cover while served by the existing BMP. The existing BMP shall be shown to have been designed and constructed in accordance with proper design standards and specifications, and to be in proper functioning condition.

C. Technology-based criteria. For land-disturbing activities, the postdeveloped stormwater runoff from the impervious cover shall be treated by an appropriate BMP as required by the postdeveloped condition percent impervious cover as specified in Table 1 of this section. The selected BMP shall be located, designed, and maintained to perform at the target pollutant removal efficiency specified in Table 1 or those found in 4VAC50-60-65. Design standards and specifications for the BMPs in Table 1 that meet the required target pollutant removal efficiency are available in the 1990 Virginia Stormwater Management Handbook. Other approved BMPs available on the Virginia Stormwater BMP Clearinghouse website at http://www.vwrrc.vt.edu/swc may also be utilized.

Part VI
VSMP General Program Requirements Related to MS4s and Land-Disturbing Activities

4VAC50-60-300. Exclusions.

The following discharges do not require VSMP state permits:

1. Any discharge of sewage from vessels, effluent from properly functioning marine engines, laundry, shower, and galley sink wastes, or any other discharge incidental to the normal operation of a vessel. This exclusion does not apply to rubbish, trash, garbage, or other such materials discharged overboard; nor to other discharges when the vessel is operating in a capacity other than as a means of transportation such as when used as an energy or mining facility, a storage facility or a seafood processing facility, or when secured to a storage facility or a seafood processing facility, or when secured to the bed of the ocean, contiguous zone or surface waters for the purpose of mineral or oil exploration or development.

2. Discharges of dredged or fill material into surface waters that are regulated under § 404 of the CWA.

3. The introduction of sewage, industrial wastes or other pollutants into publicly owned treatment works by indirect dischargers. Plans or agreements to switch to this method of disposal in the future do not relieve dischargers of the obligation to have and comply with state permits until all discharges of pollutants to surface waters are eliminated. This exclusion does not apply to the introduction of pollutants to privately owned treatment works or to other discharges through pipes, sewers, or other conveyances owned by a state, municipality, or other party not leading to treatment works.

4. Any discharge in compliance with the instructions of an on-scene coordinator pursuant to 40 CFR Part 300 (2000) (The National Oil and Hazardous Substances Pollution Contingency Plan) or 33 CFR 153.10(e) (2000) (Pollution by Oil and Hazardous Substances).

5. Any introduction of pollutants from nonpoint source agricultural and silvicultural activities, including stormwater runoff from orchards, cultivated crops, pastures, range lands, and forest lands, but not discharges from concentrated animal feeding operations, discharges from concentrated aquatic animal production facilities, discharges to aquaculture projects, and discharges from silvicultural point sources.

6. Return flows from irrigated agriculture.

B. Any person in violation of subsection A of this section, who discharges or causes or allows a discharge of stormwater into or upon state waters from Municipal Separate Storm Sewer Systems or land-disturbing activities, or who discharges or causes or allows a discharge that may reasonably be expected to enter state waters in violation of subsection A of this section, shall notify the department of the discharge immediately upon discovery of the discharge but in no case later than 24 hours after said discovery. A written report of the unauthorized discharge shall be submitted by the owner, to the department, within five days of discovery of the discharge. The written report shall contain:

1. A description of the nature and location of the discharge;

2. The cause of the discharge;

3. The date on which the discharge occurred;

4. The length of time that the discharge continued;

5. The volume of the discharge;

6. If the discharge is continuing, how long it is expected to continue;

7. If the discharge is continuing, what the expected total volume of the discharge will be; and

8. Any steps planned or taken to reduce, eliminate and prevent a recurrence of the present discharge or any future discharges not authorized by the state permit.

C. No state permit may be issued:

1. When the conditions of the state permit do not provide for compliance with the applicable requirements of the CWA or the Act, or regulations promulgated under the CWA or the Act;

2. When the state permit applicant is required to obtain a state or other appropriate certification under § 401 of the CWA and that certification has not been obtained or waived;

3. When the regional administrator has objected to issuance of the state permit;

4. When the imposition of conditions cannot ensure compliance with the applicable water quality requirements of all affected states;

5. When, in the judgment of the Secretary of the Army, anchorage and navigation in or on any of the waters of the United States would be substantially impaired by the discharge;

6. For the discharge of any radiological, chemical, or biological warfare agent or high-level radioactive waste;

7. For any discharge inconsistent with a plan or plan amendment approved under § 208(b) of the CWA;

8. For any discharge to the territorial sea, the waters of the contiguous zone, or the oceans in the following circumstances:

a. Before the promulgation of guidelines under § 403(c) of the CWA (for determining degradation of the waters of the territorial seas, the contiguous zone, and the oceans) unless the board determines state permit issuance to be in the public interest; or

b. After promulgation of guidelines under § 403(c) of the CWA, when insufficient information exists to make a reasonable judgment whether the discharge complies with them.

9. To a new source or a new discharger, if the discharge from its construction or operation will cause or contribute to the violation of water quality standards. The owner or operator of a new source or new discharger proposing to discharge into a water segment which does not meet applicable water quality standards or is not expected to meet those standards even after the application of the effluent limitations required by the Act and §§ 301(b)(1)(A) and 301(b)(1)(B) of the CWA, and for which the department has performed a pollutants load allocation for the pollutant to be discharged, must demonstrate, before the close of the public comment period, that:

a. There are sufficient remaining pollutant load allocations to allow for the discharge; and

b. The existing dischargers into that segment are subject to compliance schedules designed to bring the segment into compliance with applicable water quality standards. The board may waive the submission of information by the new source or new discharger required by this subdivision if the board determines that it already has adequate information to evaluate the request. An explanation of the development of limitations to meet the criteria of this paragraph is to be included in the fact sheet to the state permit under 4VAC50-60-520.

4VAC50-60-320

A. Except for any toxic effluent standards and prohibitions imposed under § 307 of the CWA and standards for sewage sludge use or disposal under § 405(d) of the CWA, compliance with a state permit during its term constitutes compliance, for purposes of enforcement, with the Act and with §§ 301, 302, 306, 307, 318, 403, and 405 (a) through (b) of the CWA. However, a state permit may be modified, revoked and reissued, or terminated during its term for cause as set forth in this chapter.

B. The issuance of a state permit does not convey any property rights of any sort, or any exclusive privilege.

C. The issuance of a state permit does not authorize any injury to persons or property or invasion of other private rights, or any infringement of state or local law or regulations.

4VAC50-60-330

4VAC50-60-330. Continuation of expiring state permits.

A. The state permit shall expire at the end of its term, except that the conditions of an expired state permit continue in force until the effective date of a new state permit if:

1. The permittee has submitted a timely application as required by this chapter, which is a complete application for a new state permit; and

2. The board, through no fault of the permittee, does not issue a new state permit with an effective date on or before the expiration date of the previous state permit.

B. Permits State permits continued under this section remain fully effective and enforceable.

C. When the permittee is not in compliance with the conditions of the expiring or expired state permit the board may choose to do any or all of the following:

1. Initiate enforcement action based upon the state permit which has been continued;

2. Issue a notice of intent to deny the new state permit. If the state permit is denied, the owner or operator would then be required to cease the activities authorized by the continued state permit or be subject to enforcement action for operating without a state permit;

3. Issue a new state permit with appropriate conditions; or

4. Take other actions authorized by this chapter.

4VAC50-60-340

4VAC50-60-340. Confidentiality of information.

A. The board, the department, or the permit-issuing VSMP authority may require every state permit applicant or state permittee to furnish when requested such application materials, plans, specifications, and other pertinent information as may be necessary to determine the effect of his discharge on the quality of state waters, or such other information as may be necessary to accomplish the purposes of the Act and this chapter. Any personal information shall not be disclosed except to an appropriate official of the board, department, or permit-issuing VSMP authority or as may be authorized pursuant to the Virginia Freedom of Information Act (§ 2.2-3700 et seq. of the Code of Virginia). However:

1. Disclosure of records of the department, the board, or the permit-issuing VSMP authority relating to (i) active federal environmental enforcement actions that are considered confidential under federal law and (ii) enforcement strategies, including proposed sanctions for enforcement actions is prohibited. Upon request, such records shall be disclosed after a proposed sanction resulting from the investigation has been determined by the department, the board, or the permit-issuing VSMP authority.

2. Any secret formula, secret processes, or secret methods other than effluent data submitted to the department pursuant to this chapter may be claimed as confidential by the submitter in accordance with 40 CFR 122.7 (2000).

4VAC50-60-350

4VAC50-60-350. Guidance documents.

The board may develop and use guidance, as appropriate, to implement technical and regulatory details of the VSMP state permit program. Such guidance is distinguished from regulation by the fact that it is not binding on either the board or permittees. If a more appropriate methodology than that called for in guidance is available in a given situation, the more appropriate methodology shall be used to the extent it is consistent with applicable regulations and the Stormwater Management Act.

4VAC50-60-360

Part VII
VSMP State Permit Applications

4VAC50-60-360. Application for a state permit.

A. Duty to apply. Any person who discharges or proposes to discharge stormwater into or upon state waters from Municipal Separate Storm Sewer Systems or land-disturbing activities and who does not have an effective state permit, except persons covered by general permits, excluded from the requirement for a state permit by this chapter, shall submit a complete application to the department in accordance with this section.

1. Fundamentally different factors.

a. A request for a variance based on the presence of fundamentally different factors from those on which the effluent limitations guideline was based shall be filed as follows:

(1) For a request from best practicable control technology currently available (BPT), by the close of the public comment period for the draft state permit; or

(2) For a request from best available technology economically achievable (BAT) and/or best conventional pollutant control technology (BCT), by no later than 180 days after the date on which an effluent limitation guideline is published in the Federal Register for a request based on an effluent limitation guideline promulgated on or after February 4, 1987.

b. The request shall explain how the requirements of the applicable regulatory or statutory criteria have been met.

2. A request for a variance from the BAT requirements for CWA § 301(b)(2)(F) pollutants (commonly called nonconventional pollutants) pursuant to § 301(c) of the CWA because of the economic capability of the owner or operator, or pursuant to § 301(g) of the CWA (provided, however, that a § 301(g) variance may only be requested for ammonia, chlorine, color, iron, total phenols (when determined by the administrator to be a pollutant covered by § 301(b)(2)(F) of the CWA) and any other pollutant that the administrator lists under § 301(g)(4) of the CWA) must be made as follows:

a. For those requests for a variance from an effluent limitation based upon an effluent limitation guideline by:

(1) Submitting an initial request to the regional administrator, as well as to the department, stating the name of the discharger, the state permit number, the outfall number(s), the applicable effluent guideline, and whether the discharger is requesting a § 301(c) or § 301(g) of the CWA modification, or both. This request must have been filed not later than 270 days after promulgation of an applicable effluent limitation guideline; and

(2) Submitting a completed request no later than the close of the public comment period for the draft state permit demonstrating that: (i) all reasonable ascertainable issues have been raised and all reasonably available arguments and materials supporting their position have been submitted; and (ii) that the applicable requirements of 40 CFR Part 125 (2000) have been met. Notwithstanding this provision, the complete application for a request under § 301(g) of the CWA shall be filed 180 days before EPA must make a decision (unless the Regional Administrator establishes a shorter or longer period); or

b. For those requests for a variance from effluent limitations not based on effluent limitation guidelines, the request need only comply with subdivision 2 a (2) of this subsection and need not be preceded by an initial request under subdivision 2 a (1) of this subsection.

3. A modification under § 302(b)(2) of the CWA of requirements under § 302(a) of the CWA for achieving water quality related effluent limitations may be requested no later than the close of the public comment period for the draft state permit on the state permit from which the modification is sought.

4. A variance for alternate effluent limitations for the thermal component of any discharge must be filed with a timely application for a state permit under this section, except that if thermal effluent limitations are established on a case-by-case basis or are based on water quality standards the request for a variance may be filed by the close of the public comment period for the draft state permit. A copy of the request shall be sent simultaneously to the department.

H. Expedited variance procedures and time extensions.

1. Notwithstanding the time requirements in subsection G of this section, the board may notify a state permit applicant before a draft state permit is issued that the draft state permit will likely contain limitations which are eligible for variances. In the notice the board may require the state permit applicant as a condition of consideration of any potential variance request to submit a request explaining how the requirements of 40 CFR Part 125 (2000) applicable to the variance have been met and may require its submission within a specified reasonable time after receipt of the notice. The notice may be sent before the state permit application has been submitted. The draft or final state permit may contain the alternative limitations which may become effective upon final grant of the variance.

2. A discharger who cannot file a timely complete request required under subdivisions G 2 a (2) or G 2 b of this section may request an extension. The extension may be granted or denied at the discretion of the board. Extensions shall be no more than six months in duration.

I. Recordkeeping. Permit State permit applicants shall keep records of all data used to complete state permit applications and any supplemental information submitted under this section for a period of at least three years from the date the application is signed.

I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations."

4VAC50-60-380

4VAC50-60-380. Stormwater discharges.

A. Permit State permit requirements.

1. Prior to October 1, 1994, discharges composed entirely of stormwater shall not be required to obtain a VSMP state permit except:

a. A discharge with respect to which a state permit has been issued prior to February 4, 1987;

b. A stormwater discharge associated with large construction activity;

c. A discharge from a large municipal separate storm sewer system;

d. A discharge from a medium municipal separate storm sewer system; or

e. A discharge that either the board or the regional administrator determines to contribute to a violation of a water quality standard or is a significant contributor of pollutants to surface waters. This designation may include a discharge from any conveyance or system of conveyances used for collecting and conveying stormwater runoff or a system of discharges from municipal separate storm sewers, except for those discharges from conveyances that do not require a state permit under subdivision 2 of this subsection or agricultural stormwater runoff that is exempted from the definition of point source.

The board may designate discharges from municipal separate storm sewers on a system-wide or jurisdiction-wide basis. In making this determination the board may consider the following factors:

(1) The location of the discharge with respect to surface waters;

(2) The size of the discharge;

(3) The quantity and nature of the pollutants discharged to surface waters; and

(4) Other relevant factors.

2. The board may not require a state permit for discharges of stormwater runoff from mining operations or oil and gas exploration, production, processing or treatment operations, or transmission facilities, composed entirely of flows that are from conveyances or systems of conveyances (including but not limited to pipes, conduits, ditches, and channels) used for collecting and conveying precipitation runoff and that are not contaminated by contact with or that has not come into contact with, any overburden, raw material, intermediate products, finished product, by-product or waste products located on the site of such operations.

3. a. Permits State permits must be obtained for all discharges from large and medium municipal separate storm sewer systems.

b. The board may either issue one system-wide state permit covering all discharges from municipal separate storm sewers within a large or medium municipal storm sewer system or issue distinct state permits for appropriate categories of discharges within a large or medium municipal separate storm sewer system including, but not limited to: all discharges owned or operated by the same municipality; located within the same jurisdiction; all discharges within a system that discharge to the same watershed; discharges within a system that are similar in nature; or for individual discharges from municipal separate storm sewers within the system.

c. The operator of a discharge from a municipal separate storm sewer that is part of a large or medium municipal separate storm sewer system must either:

(1) Participate in a state permit application (to be a state permittee or a state co-permittee) with one or more other operators of discharges from the large or medium municipal storm sewer system that covers all, or a portion of all, discharges from the municipal separate storm sewer system;

(2) Submit a distinct state permit application that only covers discharges from the municipal separate storm sewers for which the operator is responsible; or

4VAC50-60-390

4VAC50-60-390. Effluent sampling procedures.

VSMP State permit applicants for discharges from large and small municipal storm sewers or municipal storm sewers designated under 4VAC50-60-380 A 1 e shall provide the following information to the department, using application forms provided by the department.

A. Information on stormwater discharges that is to be provided as specified in 4VAC50-60-380. When quantitative data for a pollutant are required, the state permit applicant must collect a sample of effluent and analyze it for the pollutant in accordance with analytical methods approved under 40 CFR Part 136 (2000). When no analytical method is approved the state permit applicant may use any suitable method but must provide a description of the method. When an a state permit applicant has two or more outfalls with substantially identical effluents, the board may allow the state permit applicant to test only one outfall and report that the quantitative data also apply to the substantially identical outfalls. The requirements in e and f of this subdivision that an a state permit applicant must provide quantitative data for certain pollutants known or believed to be present do not apply to pollutants present in a discharge solely as the result of their presence in intake water; however, an applicant must report such pollutants as present. Grab samples must be used for pH, temperature, cyanide, total phenols, residual chlorine, oil and grease, fecal coliform, and fecal streptococcus. For all other pollutants, 24-hour composite samples must be used. However, a minimum of one grab sample may be taken for effluents from holding ponds or other impoundments with a retention period greater than 24 hours. In addition, for discharges other than stormwater discharges, the board may waive composite sampling for any outfall for which the state permit applicant demonstrates that the use of an automatic sampler is infeasible and that the minimum of four grab samples will be a representative sample of the effluent being discharged.

B. For stormwater discharges, all samples shall be collected from the discharge resulting from a storm event that is greater than 0.1 inch and at least 72 hours from the previously measurable (greater than 0.1 inch rainfall) storm event. Where feasible, the variance in the duration of the event and the total rainfall of the event should not exceed 50% from the average or median rainfall event in that area. For all state permit applicants, a flow-weighted composite shall be taken for either the entire discharge or for the first three hours of the discharge. The flow-weighted composite sample for a stormwater discharge may be taken with a continuous sampler or as a combination of a minimum of three sample aliquots taken in each hour of discharge for the entire discharge or for the first three hours of the discharge, with each aliquot being separated by a minimum period of 15 minutes. However, a minimum of one grab sample may be taken for stormwater discharges from holding ponds or other impoundments with a retention period greater than 24 hours. For a flow-weighted composite sample, only one analysis of the composite of aliquots is required. For stormwater discharge samples taken from discharges associated with industrial activities, quantitative data must be reported for the grab sample taken during the first 30 minutes (or as soon thereafter as practicable) of the discharge for all pollutants specified in 4VAC50-60-380 C 1. For all stormwater state permit applicants taking flow-weighted composites, quantitative data must be reported for all pollutants specified in 4VAC50-60-380 except pH, temperature, cyanide, total phenols, residual chlorine, oil and grease, fecal coliform, and fecal streptococcus. The board may allow or establish appropriate site-specific sampling procedures or requirements, including sampling locations, the season in which the sampling takes place, the minimum duration between the previous measurable storm event and the storm event sampled, the minimum or maximum level of precipitation required for an appropriate storm event, the form of precipitation sampled (snow melt or rain fall), protocols for collecting samples under 40 CFR Part 136 (2000), and additional time for submitting data on a case-by-case basis. A state permit applicant is expected to know or have reason to believe that a pollutant is present in an effluent based on an evaluation of the expected use, production, or storage of the pollutant, or on any previous analyses for the pollutant. (For example, any pesticide manufactured by a facility may be expected to be present in contaminated stormwater runoff from the facility.)

C. Every state permit applicant must report quantitative data for every outfall for the following pollutants:

Biochemical oxygen demand (BOD5)

D. The board may waive the reporting requirements for individual point sources or for a particular industry category for one or more of the pollutants listed in subsection C of this section if the state permit applicant has demonstrated that such a waiver is appropriate because information adequate to support issuance of a state permit can be obtained with less stringent requirements.

E. Each state permit applicant with processes in one or more primary industry category (see 40 CFR Part 122 Appendix A (2000)) contributing to a discharge must report quantitative data for the following pollutants in each outfall containing process wastewater:

1. The organic toxic pollutants in the fractions designated in Table I of 40 CFR Part 122 Appendix D (2000) for the state permit applicant's industrial category or categories unless the state permit applicant qualifies as a small business under subdivision 8 of this subsection. Table II of 40 CFR Part 122 Appendix D (2000) lists the organic toxic pollutants in each fraction. The fractions result from the sample preparation required by the analytical procedure that uses gas chromatography/mass spectrometry. A determination that a state permit applicant falls within a particular industrial category for the purposes of selecting fractions for testing is not conclusive as to the state permit applicant's inclusion in that category for any other purposes; and

2. The pollutants listed in Table III of 40 CFR Part 122 Appendix D (2000) (the toxic metals, cyanide, and total phenols).

F. 1. Each state permit applicant must indicate whether it knows or has reason to believe that any of the pollutants in Table IV of 40 CFR Part 122 Appendix D (2000) (certain conventional and nonconventional pollutants) is discharged from each outfall. If an applicable effluent limitations guideline either directly limits the pollutant or, by its express terms, indirectly limits the pollutant through limitations on an indicator, the state permit applicant must report quantitative data. For every pollutant discharged that is not so limited in an effluent limitations guideline, the state permit applicant must either report quantitative data or briefly describe the reasons the pollutant is expected to be discharged.

2. Each applicant must indicate whether it knows or has reason to believe that any of the pollutants listed in Table II or Table III of 40 CFR Part 122 Appendix D (2000) (the toxic pollutants and total phenols) for which quantitative data are not otherwise required under subdivision 7 e of this subsection, is discharged from each outfall. For every pollutant expected to be discharged in concentrations of 10 ppb or greater the state permit applicant must report quantitative data. For acrolein, acrylonitrile, 2,4 dinitrophenol, and 2-methyl-4,6 dinitrophenol, where any of these four pollutants are expected to be discharged in concentrations of 100 ppb or greater the state permit applicant must report quantitative data. For every pollutant expected to be discharged in concentrations less than 10 ppb, or in the case of acrolein, acrylonitrile, 2,4 dinitrophenol, and 2-methyl-4,6 dinitrophenol, in concentrations less than 100 ppb, the state permit applicant must either submit quantitative data or briefly describe the reasons the pollutant is expected to be discharged. A state permit applicant qualifying as a small business under subdivision 8 of this subsection is not required to analyze for pollutants listed in Table II of 40 CFR Part 122 Appendix D (2000) (the organic toxic pollutants).

G. Each state permit applicant must indicate whether it knows or has reason to believe that any of the pollutants in Table V of 40 CFR Part 122 Appendix D (2000) (certain hazardous substances and asbestos) are discharged from each outfall. For every pollutant expected to be discharged, the state permit applicant must briefly describe the reasons the pollutant is expected to be discharged, and report any quantitative data it has for any pollutant.

H. Each state permit applicant must report qualitative data, generated using a screening procedure not calibrated with analytical standards, for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) if it:

1. Uses or manufactures 2,4,5-trichlorophenoxy acetic acid (2,4,5,-T); 2-(2,4,5-trichlorophenoxy) propanoic acid (Silvex, 2,4,5,-TP); 2-(2,4,5-trichlorophenoxy) ethyl, 2,2-dichloropropionate (Erbon); O,O-dimethyl O-(2,4,5-trichlorophenyl) phosphorothioate (Ronnel); 2,4,5-trichlorophenol (TCP); or hexachlorophene (HCP); or

2. Knows or has reason to believe that TCDD is or may be present in an effluent.

4VAC50-60-400

4VAC50-60-400. Small municipal separate storm sewer systems.

A. Objectives of the stormwater regulations for small MS4s.

1. Subsections A through G of this section are written in a "readable regulation" format that includes both rule requirements and guidance that is not legally binding. The recommended guidance is distinguished from the regulatory requirements by putting the guidance in a separate subdivision headed by the word "Note."

2. Under the statutory mandate in § 402(p)(6) of the Clean Water Act, the purpose of this portion of the stormwater program is to designate additional sources that need to be regulated to protect water quality and to establish a comprehensive stormwater program to regulate these sources.

3. Stormwater runoff continues to harm the nation's waters. Runoff from lands modified by human activities can harm surface water resources in several ways including by changing natural hydrologic patterns and by elevating pollutant concentrations and loadings. Stormwater runoff may contain or mobilize high levels of contaminants, such as sediment, suspended solids, nutrients, heavy metals, pathogens, toxins, oxygen-demanding substances, and floatables.

4. The board strongly encourages partnerships and the watershed approach as the management framework for efficiently, effectively, and consistently protecting and restoring aquatic ecosystems and protecting public health.

B. As an operator of a small MS4, am I regulated under the VSMP state's stormwater program?

1. Unless you qualify for a waiver under subdivision 3 of this subsection, you are regulated if you operate a small MS4, including but not limited to systems operated by federal, state, tribal, and local governments, including the Virginia Department of Transportation; and

a. Your small MS4 is located in an urbanized area as determined by the latest decennial census by the Bureau of the Census (If your small MS4 is not located entirely within an urbanized area, only the portion that is within the urbanized area is regulated); or

b. You are designated by the board, including where the designation is pursuant to subdivisions C 3 a and b of this section or is based upon a petition under 4VAC50-60-380 D.

2. You may be the subject of a petition to the board to require a VSMP state permit for your discharge of stormwater. If the board determines that you need a state permit, you are required to comply with subsections C through E of this section.

3. The board may waive the requirements otherwise applicable to you if you meet the criteria of subdivision 4 or 5 of this subsection. If you receive a waiver under this section, you may subsequently be required to seek coverage under a VSMP state permit in accordance with subdivision C 1 of this section if circumstances change. (See also subdivision E 2 of this section).

4. The board may waive state permit coverage if your MS4 serves a population of less than 1,000 within the urbanized area and you meet the following criteria:

a. Your system is not contributing substantially to the pollutant loadings of a physically interconnected MS4 that is regulated by the VSMP stormwater program board; and

b. If you discharge any pollutants that have been identified as a cause of impairment of any water body to which you discharge, stormwater controls are not needed based on wasteload allocations that are part of an EPA-approved or established "total maximum daily load" (TMDL) that addresses the pollutants of concern.

5. The board may waive state permit coverage if your MS4 serves a population under 10,000 and you meet the following criteria:

a. The board has evaluated all surface waters, including small streams, tributaries, lakes, and ponds, that receive a discharge from your MS4;

b. For all such waters, the board has determined that stormwater controls are not needed based on wasteload allocations that are part of an EPA-approved or established TMDL that addresses the pollutants of concern or, if a TMDL has not been developed or approved, an equivalent analysis that determines sources and allocations for the pollutants of concern;

c. For the purpose of subdivision 5 of this subsection, the pollutants of concern include biochemical oxygen demand (BOD), sediment or a parameter that addresses sediment (such as total suspended solids, turbidity or siltation), pathogens, oil and grease, and any pollutant that has been identified as a cause of impairment of any water body that will receive a discharge from your MS4; and

d. The board has determined that future discharges from your MS4 do not have the potential to result in exceedances of water quality standards, including impairment of designated uses, or other significant water quality impacts, including habitat and biological impacts.

C. If I am an operator of a regulated small MS4, how do I apply for a VSMP state permit and when do I have to apply?

1. If you operate a regulated small MS4 under subsection B of this section, you must seek coverage under a VSMP state permit issued by the board.

2. You must seek authorization to discharge under a general or individual VSMP state permit, as follows:

a. If the board has issued a general permit applicable to your discharge and you are seeking coverage under the general permit, you must submit a registration statement that includes the information on your best management practices and measurable goals required by subdivision D 4 of this section. You may file your own registration statement, or you and other municipalities or governmental entities may jointly submit a registration statement. If you want to share responsibilities for meeting the minimum measures with other municipalities or governmental entities, you must submit a registration statement that describes which minimum measures you will implement and identify the entities that will implement the other minimum measures within the area served by your MS4. The general permit will explain any other steps necessary to obtain permit authorization.

b. (1) If you are seeking authorization to discharge under an individual state permit and wish to implement a program under subsection D of this section, you must submit an application to the board that includes the information required under 4VAC50-60-360 F and subdivision D 4 of this section, an estimate of square mileage served by your small MS4, and any additional information that the board requests. A storm sewer map that satisfies the requirement of subdivision D 2 c (1) of this section will satisfy the map requirement in 4VAC50-60-360 F 7.

(2) If you are seeking authorization to discharge under an individual state permit and wish to implement a program that is different from the program under subsection D of this section, you will need to comply with the state permit application requirements of 4VAC50-60-380 C. You must submit both parts of the application requirements in 4VAC50-60-380 C 1 and 2 by March 10, 2003. You do not need to submit the information required by 4VAC50-60-380 C 1 b and C 2 regarding your legal authority, unless you intend for the state permit writer to take such information into account when developing your other state permit conditions.

(3) If allowed by the board, you and another regulated entity may jointly apply under either subdivision 2 b (1) or (2) of this subsection to be state co-permittees under an individual state permit.

c. If your small MS4 is in the same urbanized area as a medium or large MS4 with a VSMP stormwater state permit and that other MS4 is willing to have you participate in its stormwater program, you and the other MS4 may jointly seek a modification of the other MS4 state permit to include you as a limited state co-permittee. As a limited state co-permittee, you will be responsible for compliance with the state permit's conditions applicable to your jurisdiction. If you choose this option you will need to comply with the state permit application requirements of 4VAC50-60-380, rather than the requirements of subsection D of this section. You do not need to comply with the specific application requirements of 4VAC50-60-380 C 1 c and d and 4VAC50-60-380 C 2 c (discharge characterization). You may satisfy the requirements in 4VAC50-60-380 C 1 e and 2 d (identification of a management program) by referring to the other MS4's stormwater management program.

d. NOTE: In referencing an MS4's stormwater management program, you should briefly describe how the existing plan will address discharges from your small MS4 or would need to be supplemented in order to adequately address your discharges. You should also explain your role in coordinating stormwater pollutant control activities in your MS4 and detail the resources available to you to accomplish the plan.

3. If you operate a regulated small MS4:

a. Designated under subdivision B 1 a of this section, you must apply for coverage under a VSMP state permit or apply for a modification of an existing VSMP state permit under subdivision 2 c of this subsection by March 10, 2003.

b. Designated under subdivision B 1 b of this section, you must apply for coverage under a VSMP state permit or apply for a modification of an existing VPDES permit under subdivision 2 c of this subsection within 180 days of notice, unless the board grants a later date.

D. As an operator of a regulated small MS4, what will my VSMP MS4 stormwater state permit require?

1. Your VSMP MS4 state permit will require at a minimum that you develop, implement, and enforce a stormwater management program designed to reduce the discharge of pollutants from your MS4 to the maximum extent practicable (MEP), to protect water quality, and to satisfy the appropriate water quality requirements of the Clean Water Act, the Virginia Stormwater Management Act, and the State Water Control Law. Your stormwater management program must include the minimum control measures described in subdivision 2 of this subsection unless you apply for a state permit under 4VAC50-60-380 C. For purposes of this section, narrative effluent limitations requiring implementation of best management practices (BMPs) are generally the most appropriate form of effluent limitations when designed to satisfy technology requirements (including reductions of pollutants to the maximum extent practicable) and to protect water quality. Implementation of best management practices consistent with the provisions of the stormwater management program required pursuant to this section and the provisions of the state permit required pursuant to subsection C of this section constitutes compliance with the standard of reducing pollutants to the maximum extent practicable. The board will specify a time period of up to five years from the date of state permit issuance for you to develop and implement your program.

2. Minimum control measures.

a. Public education and outreach on stormwater impacts.

(1) You must implement a public education program to distribute educational materials to the community or conduct equivalent outreach activities about the impacts of stormwater discharges on water bodies and the steps that the public can take to reduce pollutants in stormwater runoff.

(2) NOTE: You may use stormwater educational materials provided by the state, your tribe, EPA, environmental, public interest or trade organizations, or other MS4s. The public education program should inform individuals and households about the steps they can take to reduce stormwater pollution, such as ensuring proper septic system maintenance, ensuring the proper use and disposal of landscape and garden chemicals including fertilizers and pesticides, protecting and restoring riparian vegetation, and properly disposing of used motor oil or household hazardous wastes. The board recommends that the program inform individuals and groups how to become involved in local stream and beach restoration activities as well as activities that are coordinated by youth service and conservation corps or other citizen groups. The board recommends that the public education program be tailored, using a mix of locally appropriate strategies, to target specific audiences and communities. Examples of strategies include: distributing brochures or fact sheets, sponsoring speaking engagements before community groups, providing public service announcements, implementing educational programs targeted at school-age children, and conducting community-based projects such as storm drain stenciling, and watershed and beach cleanups. In addition, the board recommends that some of the materials or outreach programs be directed toward targeted groups of commercial, industrial, and institutional entities likely to have significant stormwater impacts. For example, providing information to restaurants on the impact of grease clogging storm drains and to garages on the impact of oil discharges. You are encouraged to tailor your outreach program to address the viewpoints and concerns of all communities, particularly minority and disadvantaged communities, as well as any special concerns relating to children.

b. Public involvement/participation.

(1) You must, at a minimum, comply with state, tribal, and local public notice requirements when implementing a public involvement/participation program.

(2) The board recommends that the public be included in developing, implementing, and reviewing your stormwater management program and that the public participation process should make efforts to reach out and engage all economic and ethnic groups. Opportunities for members of the public to participate in program development and implementation include serving as citizen representatives on a local stormwater management panel, attending public hearings, working as citizen volunteers to educate other individuals about the program, assisting in program coordination with other pre-existing programs, or participating in volunteer monitoring efforts. (Citizens should obtain approval where necessary for lawful access to monitoring sites.)

c. Illicit discharge detection and elimination.

(1) You must develop, implement and enforce a program to detect and eliminate illicit discharges (as defined in 4VAC50-60-10) into your small MS4.

(2) You must:

(a) Develop, if not already completed, a storm sewer system map, showing the location of all outfalls and the names and location of all surface waters that receive discharges from those outfalls;

(b) To the extent allowable under state, tribal or local law, effectively prohibit, through ordinance or other regulatory mechanism, nonstormwater discharges into your storm sewer system and implement appropriate enforcement procedures and actions;

(c) Develop and implement a plan to detect and address nonstormwater discharges, including illegal dumping, to your system; and

(d) Inform public employees, businesses, and the general public of hazards associated with illegal discharges and improper disposal of waste.

(3) You need to address the following categories of nonstormwater discharges or flows (i.e., illicit discharges) only if you identify them as significant contributors of pollutants to your small MS4: water line flushing, landscape irrigation, diverted stream flows, rising groundwaters, uncontaminated groundwater infiltration (as defined in 40 CFR 35.2005(20) (2000)), uncontaminated pumped groundwater, discharges from potable water sources, foundation drains, air conditioning condensation, irrigation water, springs, water from crawl space pumps, footing drains, lawn watering, individual residential car washing, flows from riparian habitats and wetlands, dechlorinated swimming pool discharges, and street wash water. (Discharges or flows from fire-fighting activities are excluded from the effective prohibition against nonstormwater and need only be addressed where they are identified as significant sources of pollutants to surface waters.)

(4) NOTE: The board recommends that the plan to detect and address illicit discharges include the following four components: (i) procedures for locating priority areas likely to have illicit discharges, (ii) procedures for tracing the source of an illicit discharge, (iii) procedures for removing the source of the discharge, and (iv) procedures for program evaluation and assessment. The board recommends visually screening outfalls during dry weather and conducting field tests of selected pollutants as part of the procedures for locating priority areas. Illicit discharge education actions may include storm drain stenciling; a program to promote, publicize, and facilitate public reporting of illicit connections or discharges; and distribution of outreach materials.

d. Construction site stormwater runoff control.

(1) You must develop, implement, and enforce a program to reduce pollutants in any stormwater runoff to your small MS4 from construction activities that result in a land disturbance of greater than or equal to one acre, or equal to or greater than 2,500 square feet in all areas of the jurisdictions designated as subject to the Chesapeake Bay Preservation Area Designation and Management Regulations adopted pursuant to the Chesapeake Bay Preservation Act. Reduction of stormwater discharges from construction activity disturbing less than one acre must be included in your program if that construction activity is part of a larger common plan of development or sale that would disturb one acre or more. If the board waives requirements for stormwater discharges associated with small construction activity in accordance with the definition in 4VAC50-60-10, you are not required to develop, implement, and/or enforce a program to reduce pollutant discharges from such sites.

(2) Your program must include the development and implementation of, at a minimum:

(a) An ordinance or other regulatory mechanism to require erosion and sediment controls, as well as sanctions to ensure compliance, to the extent allowable under state, tribal, or local law;

(b) Requirements for construction site operators to implement appropriate erosion and sediment control best management practices;

(c) Requirements for construction site operators to control waste such as discarded building materials, concrete truck washout, chemicals, litter, and sanitary waste at the construction site that may cause adverse impacts to water quality;

(d) Procedures for site plan review which incorporate consideration of potential water quality impacts;

(e) Procedures for receipt and consideration of information submitted by the public; and

(f) Procedures for site inspection and enforcement of control measures.

(3) NOTE: Examples of sanctions to ensure compliance include nonmonetary penalties, fines, bonding requirements and/or state permit denials for noncompliance. The board recommends that procedures for site plan review include the review of individual pre-construction site plans to ensure consistency with local sediment and erosion control VESCP requirements. Procedures for site inspections and enforcement of control measures could include steps to identify priority sites for inspection and enforcement based on the nature of the construction activity, topography, and the characteristics of soils and receiving water quality. You are encouraged to provide appropriate educational and training measures for construction site operators. You may wish to require a stormwater pollution prevention plan for construction sites within your jurisdiction that discharge into your system. (See 4VAC50-60-460 L and subdivision E 2 of this section.) The board may recognize that another government entity may be responsible for implementing one or more of the minimum measures on your behalf.

e. Post-construction stormwater management in new development and redevelopment.

(1) You must develop, implement, and enforce a program to address stormwater runoff from new development and redevelopment projects that disturb greater than or equal to one acre, including projects less than one acre that are part of a larger common plan of development or sale, that discharge into your small MS4. Your program must ensure that controls are in place that would prevent or minimize water quality impacts.

(2) You must:

(a) Develop and implement strategies that include a combination of structural and/or nonstructural best management practices (BMPs) appropriate for your community;

(b) Use an ordinance or other regulatory mechanism to address post-construction runoff from new development and redevelopment projects to the extent allowable under state, tribal or local law; and

(c) Ensure adequate long-term operation and maintenance of BMPs.

(3) NOTE: If water quality impacts are considered from the beginning stages of a project, new development and potentially redevelopment provide more opportunities for water quality protection. The board recommends that the BMPs chosen be appropriate for the local community, minimize water quality impacts, and attempt to maintain pre-development runoff conditions. In choosing appropriate BMPs, the board encourages you to participate in locally based watershed planning efforts that attempt to involve a diverse group of stakeholders, including interested citizens. When developing a program that is consistent with this measure's intent, the board recommends that you adopt a planning process that identifies the municipality's program goals (e.g., minimize water quality impacts resulting from post-construction runoff from new development and redevelopment), implementation strategies (e.g., adopt a combination of structural and/or nonstructural BMPs), operation and maintenance policies and procedures, and enforcement procedures. In developing your program, you should consider assessing existing ordinances, policies, programs and studies that address stormwater runoff quality. In addition to assessing these existing documents and programs, you should provide opportunities to the public to participate in the development of the program. Nonstructural BMPs are preventative actions that involve management and source controls such as: (i) policies and ordinances that provide requirements and standards to direct growth to identified areas, protect sensitive areas such as wetlands and riparian areas, maintain and/or increase open space (including a dedicated funding source for open space acquisition), provide buffers along sensitive water bodies, minimize impervious surfaces, and minimize disturbance of soils and vegetation; (ii) policies or ordinances that encourage infill development in higher density urban areas, and areas with existing infrastructure; (iii) education programs for developers and the public about project designs that minimize water quality impacts; and (iv) measures such as minimization of percent impervious area after development and minimization of directly connected impervious areas. Structural BMPs include: storage practices such as wet ponds and extended-detention outlet structures; filtration practices such as grassed swales, sand filters and filter strips; and infiltration practices such as infiltration basins and infiltration trenches. The board recommends that you ensure the appropriate implementation of the structural BMPs by considering some or all of the following: pre-construction review of BMP designs; inspections during construction to verify BMPs are built as designed; post-construction inspection and maintenance of BMPs; and penalty provisions for the noncompliance with design, construction or operation and maintenance. Stormwater technologies are constantly being improved, and the board recommends that your requirements be responsive to these changes, developments or improvements in control technologies.

f. Pollution prevention/good housekeeping for municipal operations.

(1) You must develop and implement an operation and maintenance program that includes a training component and has the ultimate goal of preventing or reducing pollutant runoff from municipal operations. Using training materials that are available from EPA, state, tribe, or other organizations, your program must include employee training to prevent and reduce stormwater pollution from activities such as park and open space maintenance, fleet and building maintenance, new construction and land disturbances, and stormwater system maintenance.

(2) NOTE: The board recommends that, at a minimum, you consider the following in developing your program: maintenance activities, maintenance schedules, and long-term inspection procedures for structural and nonstructural stormwater controls to reduce floatables and other pollutants discharged from your separate storm sewers; controls for reducing or eliminating the discharge of pollutants from streets, roads, highways, municipal parking lots, maintenance and storage yards, fleet or maintenance shops with outdoor storage areas, salt/sand storage locations and snow disposal areas operated by you, and waste transfer stations; procedures for properly disposing of waste removed from the separate storm sewers and areas listed above (such as dredge spoil, accumulated sediments, floatables, and other debris); and ways to ensure that new flood management projects assess the impacts on water quality and examine existing projects for incorporating additional water quality protection devices or practices. Operation and maintenance should be an integral component of all stormwater management programs. This measure is intended to improve the efficiency of these programs and require new programs where necessary. Properly developed and implemented operation and maintenance programs reduce the risk of water quality problems.

3. If an existing qualifying local program VSMP requires you to implement one or more of the minimum control measures of subdivision 2 of this subsection, the board may include conditions in your VPDES state permit that direct you to follow that qualifying program's VSMP's requirements rather than the requirements of subdivision 2 of this subsection. A qualifying local program VSMP is a local, state or tribal municipal stormwater management program that imposes, at a minimum, the relevant requirements of subdivision 2 of this subsection.

4. a. In your state permit application (either a registration statement for coverage under a general permit or an individual permit application), you must identify and submit to the board the following information:

(1) The best management practices (BMPs) that you or another entity will implement for each of the stormwater minimum control measures provided in subdivision 2 of this subsection;

(2) The measurable goals for each of the BMPs including, as appropriate, the months and years in which you will undertake required actions, including interim milestones and the frequency of the action; and

(3) The person or persons responsible for implementing or coordinating your stormwater management program.

b. If you obtain coverage under a general permit, you are not required to meet any measurable goals identified in your registration statement in order to demonstrate compliance with the minimum control measures in subdivisions 2 c through f of this subsection unless, prior to submitting your registration statement, EPA or the board has provided or issued a menu of BMPs that addresses each such minimum measure. Even if no regulatory authority issues the menu of BMPs, however, you still must comply with other requirements of the general permit, including good faith implementation of BMPs designed to comply with the minimum measures.

c. NOTE: Either EPA or the board will provide a menu of BMPs. You may choose BMPs from the menu or select others that satisfy the minimum control measures.

5. a. You must comply with any more stringent effluent limitations in your state permit, including state permit requirements that modify or are in addition to the minimum control measures based on an approved total maximum daily load (TMDL) or equivalent analysis. The board may include such more stringent limitations based on a TMDL or equivalent analysis that determines such limitations are needed to protect water quality.

b. NOTE: The board strongly recommends that until the evaluation of the stormwater program in subsection G of this section, no additional requirements beyond the minimum control measures be imposed on regulated small MS4s without the agreement of the operator of the affected small MS4, except where an approved TMDL or equivalent analysis provides adequate information to develop more specific measures to protect water quality.

6. You must comply with other applicable VSMP state permit requirements, standards and conditions established in the individual or general permit developed consistent with the provisions of 9VAC25-31-190 through 9VAC25-31-250, as appropriate.

7. Evaluation and assessment.

a. You must evaluate program compliance, the appropriateness of your identified best management practices, and progress towards achieving your identified measurable goals. The board may determine monitoring requirements for you in accordance with monitoring plans appropriate to your watershed. Participation in a group monitoring program is encouraged.

b. You must keep records required by the VSMP state permit for at least three years. You must submit your records to the department only when specifically asked to do so. You must make your records, including a description of your stormwater management program, available to the public at reasonable times during regular business hours (see 4VAC50-60-340 for confidentiality provision). You may assess a reasonable charge for copying. You may require a member of the public to provide advance notice.

c. Unless you are relying on another entity to satisfy your VSMP state permit obligations under subdivision E 1 of this section, you must submit annual reports to the department for your first state permit term. For subsequent state permit terms, you must submit reports in years two and four unless the department requires more frequent reports. Your report must include:

(1) The status of compliance with state permit conditions, an assessment of the appropriateness of your identified best management practices and progress towards achieving your identified measurable goals for each of the minimum control measures;

(2) Results of information collected and analyzed, including monitoring data, if any, during the reporting period;

(3) A summary of the stormwater activities you plan to undertake during the next reporting cycle;

(4) A change in any identified best management practices or measurable goals for any of the minimum control measures; and

(5) Notice that you are relying on another governmental entity to satisfy some of your state permit obligations (if applicable).

E. As an operator of a regulated small MS4, may I share the responsibility to implement the minimum control measures with other entities?

1. You may rely on another entity to satisfy your VSMP state permit obligations to implement a minimum control measure if:

a. The other entity, in fact, implements the control measure;

b. The particular control measure, or component thereof, is at least as stringent as the corresponding VSMP state permit requirement; and

c. The other entity agrees to implement the control measure on your behalf. In the reports you must submit under subdivision D 7 c of this section, you must also specify that you rely on another entity to satisfy some of your state permit obligations. If you are relying on another governmental entity regulated under the VSMP state permit program to satisfy all of your state permit obligations, including your obligation to file periodic reports required by subdivision D 7 c of this section, you must note that fact in your registration statement, but you are not required to file the periodic reports. You remain responsible for compliance with your state permit obligations if the other entity fails to implement the control measure (or component thereof). Therefore, the board encourages you to enter into a legally binding agreement with that entity if you want to minimize any uncertainty about compliance with your state permit.

2. In some cases, the board may recognize, either in your individual VSMP permit or in a VSMP general permit, that another governmental entity is responsible under a VSMP state permit for implementing one or more of the minimum control measures for your small MS4. Where the board does so, you are not required to include such minimum control measure(s) in your stormwater management program. Your state permit may be reopened and modified to include the requirement to implement a minimum control measure if the entity fails to implement it.

F. As an operator of a regulated small MS4, what happens if I don't comply with the application or state permit requirements in subsections C through E of this section?

VSMP State permits are enforceable under the Clean Water Act and the Virginia Stormwater Management Act. Violators may be subject to the enforcement actions and penalties described in Clean Water Act §§ 309 (b), (c), and (g) and 505 or under §§ 10.1-603.12:1 through 10.1-603.14 of the Code of Virginia. Compliance with a state permit issued pursuant to § 402 of the Clean Water Act is deemed compliance, for purposes of §§ 309 and 505, with §§ 301, 302, 306, 307, and 403, except any standard imposed under § 307 for toxic pollutants injurious to human health. If you are covered as a state co-permittee under an individual permit or under a general permit by means of a joint registration statement, you remain subject to the enforcement actions and penalties for the failure to comply with the terms of the state permit in your jurisdiction except as set forth in subdivision E 2 of this section.

G. Will the small MS4 stormwater program regulations at subsections B through F of this section change in the future?

The board will evaluate the small MS4 regulations at subsections B through F of this section after December 10, 2012, and make any necessary revisions. (EPA intends to conduct an enhanced research effort and compile a comprehensive evaluation of the NPDES MS4 stormwater program. The board will reevaluate the regulations based on data from the EPA NPDES MS4 stormwater program, from research on receiving water impacts from stormwater, and the effectiveness of best management practices (BMPs), as well as other relevant information sources.)

4VAC50-60-410

4VAC50-60-410. General permits.

A. The board may issue a general permit in accordance with the following:

1. The general permit shall be written to cover one or more categories or subcategories of discharges, except those covered by individual permits, within a geographic area. The area should correspond to existing geographic or political boundaries, such as:

a. Designated planning areas under §§ 208 and 303 of CWA;

b. Sewer districts or sewer authorities;

c. City, county, or state political boundaries;

d. State highway systems;

e. Standard metropolitan statistical areas as defined by the Office of Management and Budget;

f. Urbanized areas as designated by the Bureau of the Census according to criteria in 30 FR 15202 (May 1, 1974); or

g. Any other appropriate division or combination of boundaries.

2. The general permit may be written to regulate one or more categories within the area described in subdivision 1 of this subsection, where the sources within a covered subcategory of discharges are stormwater point sources.

3. Where sources within a specific category of dischargers are subject to water quality-based limits imposed pursuant to 4VAC50-60-460, the sources in that specific category or subcategory shall be subject to the same water quality-based effluent limitations.

4. The general permit must clearly identify the applicable conditions for each category or subcategory of dischargers covered by the permit.

5. The general permit may exclude specified sources or areas from coverage.

B. Administration.

1. General permits may be issued, modified, revoked and reissued, or terminated in accordance with applicable requirements of this chapter.

2. Authorization to discharge.

a. Except as provided in subdivisions 2 e and 2 f of this subsection, dischargers seeking coverage under a general permit shall submit to the department a written notice of intent to be covered by the general permit. A discharger who fails to submit a notice of intent in accordance with the terms of the state permit is not authorized to discharge, under the terms of the general permit unless the general permit, in accordance with subdivision 2 e of this subsection, contains a provision that a notice of intent is not required or the board notifies a discharger (or treatment works treating domestic sewage) that it is covered by a general permit in accordance with subdivision 2 f of this subsection. A complete and timely notice of intent (NOI) to be covered in accordance with general permit requirements fulfills the requirements for permit applications for the purposes of this chapter.

b. The contents of the notice of intent shall be specified in the general permit and shall require the submission of information necessary for adequate program implementation, including at a minimum, the legal name and address of the owner or operator, the facility name and address, type of facility or discharges, and the receiving stream or streams. All notices of intent shall be signed in accordance with 4VAC50-60-370.

c. General permits shall specify the deadlines for submitting notices of intent to be covered and the date or dates when a discharger is authorized to discharge under the state permit.

d. General permits shall specify whether a discharger that has submitted a complete and timely notice of intent to be covered in accordance with the general permit and that is eligible for coverage under the state permit, is authorized to discharge in accordance with the state permit either upon receipt of the notice of intent by the department, after a waiting period specified in the general permit, on a date specified in the general permit, or upon receipt of notification of inclusion by the board. Coverage may be terminated or revoked in accordance with subdivision 3 of this subsection.

e. Stormwater discharges associated with small construction activity may, at the discretion of the board, be authorized to discharge under a general permit without submitting a notice of intent where the board finds that a notice of intent requirement would be inappropriate. In making such a finding, the board shall consider the (i) type of discharge, (ii) expected nature of the discharge, (iii) potential for toxic and conventional pollutants in the discharges, (iv) expected volume of the discharges, (v) other means of identifying discharges covered by the state permit, and (vi) estimated number of discharges to be covered by the state permit. The board shall provide in the public notice of the general permit the reasons for not requiring a notice of intent.

f. The board may notify a discharger that it is covered by a general permit, even if the discharger has not submitted a notice of intent to be covered. A discharger so notified may request an individual permit under subdivision 3 c of this subsection.

3. Requiring an individual permit.

a. The board may require any discharger authorized by a general permit to apply for and obtain an individual VSMP permit. Any interested person may request the board to take action under this subdivision. Cases where an individual VSMP permit may be required include the following:

(1) The discharger is not in compliance with the conditions of the general VSMP permit;

(2) A change has occurred in the availability of demonstrated technology or practices for the control or abatement of pollutants applicable to the point source;

(3) Effluent limitation guidelines are promulgated for point sources covered by the general VSMP permit;

(4) A water quality management plan, established by the State Water Control Board pursuant to 9VAC25-720, containing requirements applicable to such point sources is approved;

(5) Circumstances have changed since the time of the request to be covered so that the discharger is no longer appropriately controlled under the general permit, or either a temporary or permanent reduction or elimination of the authorized discharge is necessary;

(6) The discharge(s) is a significant contributor of pollutants. In making this determination, the board may consider the following factors:

(a) The location of the discharge with respect to surface waters;

(b) The size of the discharge;

(c) The quantity and nature of the pollutants discharged to surface waters; and

(d) Other relevant factors;

b. Permits State permits required on a case-by-case basis.

(1) The board may determine, on a case-by-case basis, that certain stormwater discharges, and certain other facilities covered by general permits that do not generally require an individual permit may be required to obtain an individual permit because of their contributions to water pollution.

(2) Whenever the board decides that an individual permit is required under this subsection, except as provided in subdivision 3 b (3) of this subsection, the board shall notify the discharger in writing of that decision and the reasons for it, and shall send an application form with the notice. The discharger must apply for a permit within 60 days of notice, unless permission for a later date is granted by the board. The question whether the designation was proper will remain open for consideration during the public comment period for the draft state permit and in any subsequent public hearing.

(3) Prior to a case-by-case determination that an individual permit is required for a stormwater discharge under this subsection, the board may require the discharger to submit a state permit application or other information regarding the discharge under the Act and § 308 of the CWA. In requiring such information, the board shall notify the discharger in writing and shall send an application form with the notice. The discharger must apply for a state permit under 4VAC50-60-380 A 1 within 60 days of notice or under 4VAC50-60-380 A 8 within 180 days of notice, unless permission for a later date is granted by the board. The question whether the initial designation was proper will remain open for consideration during the public comment period for the draft state permit and in any subsequent public hearing.

c. Any owner or operator authorized by a general permit may request to be excluded from the coverage of the general permit by applying for an individual permit. The owner or operator shall submit an application under 4VAC50-60-360 with reasons supporting the request. The request shall be processed under the applicable parts of this chapter. The request shall be granted by issuing of an individual permit if the reasons cited by the owner or operator are adequate to support the request.

d. When an individual VSMP permit is issued to an owner or operator otherwise subject to a general VSMP permit, the applicability of the general permit to the individual VSMP permit state permittee is automatically terminated on the effective date of the individual permit.

e. A source excluded from a general permit solely because it already has an individual permit may request that the individual permit be revoked, and that it be covered by the general permit. Upon revocation of the individual permit, the general permit shall apply to the source.

4VAC50-60-420

4VAC50-60-420. New sources and new dischargers.

A. Criteria for new source determination.

1. Except as otherwise provided in an applicable new source performance standard, a source is a new source if it meets the definition of new source in this chapter, and

a. It is constructed at a site at which no other source is located; or

b. It totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or

c. Its processes are substantially independent of an existing source at the same site. In determining whether these processes are substantially independent, the board shall consider such factors as the extent to which the new facility is integrated with the existing plant and the extent to which the new facility is engaged in the same general type of activity as the existing source.

2. A source meeting the requirements of subdivisions 1 a, b, or c of this subsection is a new source only if a new source performance standard is independently applicable to it. If there is no such independently applicable standard, the source is a new discharger.

3. Construction on a site at which an existing source is located results in a  state permit modification subject to 4VAC50-60-630 rather than a new source (or a new discharger) if the construction does not create a new building, structure, facility, or installation meeting the criteria of subdivisions 1 b or c of this subsection but otherwise alters, replaces, or adds to existing process or production equipment.

4. Construction of a new source has commenced if the owner or operator has:

a. Begun, or caused to begin as part of a continuous on-site construction program:

(1) Any placement, assembly, or installation of facilities or equipment; or

(2) Significant site preparation work including clearing, excavation or removal of existing buildings, structures, or facilities which is necessary for the placement, assembly, or installation of new source facilities or equipment; or

b. Entered into a binding contractual obligation for the purchase of facilities or equipment which are intended to be used in its operation within a reasonable time. Options to purchase or contracts which can be terminated or modified without substantial loss, and contracts for feasibility engineering, and design studies do not constitute a contractual obligation under the paragraph.

B. Effect of compliance with new source performance standards. The provisions of this subsection do not apply to existing sources which modify their pollution control facilities or construct new pollution control facilities and achieve performance standards, but which are neither new sources or new dischargers or otherwise do not meet the requirements of this subdivision.

1. Except as provided in subdivision 2 of this subsection, any new discharger, the construction of which commenced after October 18, 1972, or new source which meets the applicable promulgated new source performance standards before the commencement of discharge, may not be subject to any more stringent new source performance standards or to any more stringent technology-based standards under § 301(b)(2) of the CWA for the soonest ending of the following periods:

a. Ten years from the date that construction is completed;

b. Ten years from the date the source begins to discharge process or other nonconstruction related wastewater; or

c. The period of depreciation or amortization of the facility for the purposes of § 167 or § 169 (or both) of the Internal Revenue Code of 1954 (26 USC 167 and 26 USC 169, respectively).

2. The protection from more stringent standards of performance afforded by subdivision 1 of this subsection does not apply to:

a. Additional or more stringent  state permit conditions that are not technology based; for example, conditions based on water quality standards, or toxic effluent standards or prohibitions under the Act and § 307(a) of the CWA; or

b. Additional state permit conditions controlling toxic pollutants or hazardous substances that are not controlled by new source performance standards. This includes state permit conditions controlling pollutants other than those identified as toxic pollutants or hazardous substances when control of these pollutants has been specifically identified as the method to control the toxic pollutants or hazardous substances.

3. When a VPDES or VSMP state permit issued to a source with a protection period under subdivision 1 of this subsection will expire on or after the expiration of the protection period, that permit shall require the owner or operator of the source to comply with the requirements of § 301 of the CWA and any other then applicable requirements of the CWA and the Act immediately upon the expiration of the protection period. No additional period for achieving compliance with these requirements may be allowed except when necessary to achieve compliance with requirements promulgated less than three years before the expiration of the protection period.

4. The owner or operator of a new source, a new discharger which commenced discharge after August 13, 1979, or a recommencing discharger shall install and have in operating condition, and shall start-up all pollution control equipment required to meet the conditions of its  state permits before beginning to discharge. Within the shortest feasible time (not to exceed 90 days), the owner or operator must meet all state permit conditions. The requirements of this paragraph do not apply if the owner or operator is issued a state permit containing a compliance schedule under 4VAC50-60-490 A 2.

5. After the effective date of new source performance standards, it shall be unlawful for any owner or operator of any new source to operate the source in violation of those standards applicable to the source.

4VAC50-60-430

Part VIII
VSMP State Permit Conditions

4VAC50-60-430. Conditions applicable to all permits.

The following conditions apply to all VSMP state permits. Additional conditions applicable to VSMP state permits are in 4VAC50-60-440. All conditions applicable to VSMP state permits shall be incorporated into the state permits either expressly or by reference. If incorporated by reference, a specific citation to this regulation must be given in the state permit.

A. The state permittee shall comply with all conditions of the state permit. Any state permit noncompliance constitutes a violation of the Act and the CWA, except that noncompliance with certain provisions of the state permit may constitute a violation of the Act but not the CWA. Permit State permit noncompliance is grounds for enforcement action; for state permit termination, revocation and reissuance, or modification; or denial of a state permit renewal application.

The state permittee shall comply with effluent standards or prohibitions established under § 307(a) of the CWA for toxic pollutants within the time provided in the chapters that establish these standards or prohibitions, even if the state permit has not yet been modified to incorporate the requirement.

B. If the state permittee wishes to continue an activity regulated by the state permit after the expiration date of the state permit, the state permittee must apply for and obtain a new state permit.

C. It shall not be a defense for a state permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of the state permit.

D. The state permittee shall take all reasonable steps to minimize or prevent any discharge in violation of the state permit that has a reasonable likelihood of adversely affecting human health or the environment.

E. The state 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 state permittee to achieve compliance with the conditions of the state permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems that are installed by a state permittee only when the operation is necessary to achieve compliance with the conditions of the state permit.

F. Permits State permits may be modified, revoked and reissued, or terminated for cause. The filing of a request by the state permittee for a state permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any state permit condition.

G. Permits State permits do not convey any property rights of any sort, or any exclusive privilege.

H. The state permittee shall furnish to the department, within a reasonable time, any information that the board may request to determine whether cause exists for modifying, revoking and reissuing, or terminating the state permit or to determine compliance with the state permit. The board may require the state permittee to furnish, upon request, such plans, specifications, and other pertinent information as may be necessary to determine the effect of the wastes from his discharge on the quality of state waters, or such other information as may be necessary to accomplish the purposes of the Act. The state permittee shall also furnish to the department upon request, copies of records required to be kept by the state permit.

I. The state permittee shall allow the director as the board's designee, or an authorized representative (including an authorized contractor acting as a representative of the administrator), upon presentation of credentials and other documents as may be required by law, to:

1. Enter upon the state permittee's premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of the state permit;

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

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

4. Sample or monitor at reasonable times, for the purposes of assuring state permit compliance or as otherwise authorized by the CWA and the Act, any substances or parameters at any location.

J. Monitoring and records.

1. Samples and measurements taken for the purpose of monitoring shall be representative of the monitored activity.

2. The state permittee shall retain records of all monitoring information, including all calibration and maintenance records and all original strip chart recordings for continuous monitoring instrumentation, copies of all reports required by the state permit, and records of all data used to complete the application for the state permit, for a period of at least three years from the date of the sample, measurement, report or application. This period of retention shall be extended automatically during the course of any unresolved litigation regarding the regulated activity or regarding control standards applicable to the state permittee, or as requested by the board.

3. Records of monitoring information shall include:

a. The date, exact place, and time of sampling or measurements;

b. The individual or individuals who performed the sampling or measurements;

c. The date or dates analyses were performed;

d. The individual or individuals who performed the analyses;

e. The analytical techniques or methods used; and

f. The results of such analyses.

4. Monitoring results must be conducted according to test procedures approved under 40 CFR Part 136 (2000) or alternative EPA approved methods, unless other test procedures have been specified in the state permit.

K. All applications, reports, or information submitted to the permit-issuing VSMP authority and department shall be signed and certified as required by 4VAC50-60-370.

L. Reporting requirements.

1. The state permittee shall give notice to the department as soon as possible of any planned physical alterations or additions to the permitted facility. Notice is required only when:

a. The alteration or addition to a permitted facility may meet one of the criteria for determining whether a facility is a new source in 4VAC50-60-420 A; or

b. The alteration or addition could significantly change the nature or increase the quantity of pollutants discharged. This notification applies to pollutants that are not subject to effluent limitations in the state permit.

2. The state permittee shall give advance notice to the department of any planned changes in the permitted facility or activity that may result in noncompliance with state permit requirements.

3. Permits State permits are not transferable to any person except after notice to the department. The board may require modification or revocation and reissuance of state permits to change the name of the state permittee and incorporate such other requirements as may be necessary under the Act or the CWA.

4. Monitoring results shall be reported at the intervals specified in the state permit.

a. Monitoring results must be reported on a Discharge Monitoring Report (DMR) or forms provided or specified by the department.

b. If the state permittee monitors any pollutant specifically addressed by the state permit more frequently than required by the state permit using test procedures approved under 40 CFR Part 136 (2000) or as otherwise specified in the state permit, the results of this monitoring shall be included in the calculation and reporting of the data submitted in the DMR or reporting form specified by the department.

c. Calculations for all limitations that require averaging of measurements shall utilize an arithmetic mean unless otherwise specified in the permit.

5. Reports of compliance or noncompliance with, or any progress reports on, interim and final requirements contained in any compliance schedule of the state permit shall be submitted no later than 14 days following each schedule date.

6. If any unusual or extraordinary discharge including a bypass or upset should occur from a facility and such discharge enters or could be expected to enter state waters, the state permitee shall promptly notify, in no case later than 24 hours, the Department of Environmental Quality and the department by telephone after the discovery of such discharge. This notification shall provide all available details of the incident, including any adverse affects on aquatic life and the known number of fish killed. The state permittee shall reduce the report to writing and shall submit it to the Department of Environmental Quality and the department within five days of discovery of the discharge in accordance with subdivision 7 a of this subsection. Unusual and extraordinary discharges include but are not limited to any discharge resulting from:

a. Unusual spillage of materials resulting directly or indirectly from processing operations;

b. Breakdown of processing or accessory equipment;

c. Failure or taking out of service of the treatment plant or auxiliary facilities (such as sewer lines or wastewater pump stations); and

d. Flooding or other acts of nature.

7. Twenty-four hour reporting.

a. The state permittee shall report any noncompliance which may endanger health or the environment. Any information shall be provided orally within 24 hours from the time the state permittee becomes aware of the circumstances. A written submission shall also be provided within five days of the time the state permittee becomes aware of the circumstances. The written submission shall contain a description of the noncompliance and its cause; the period of noncompliance, including exact dates and times, and if the noncompliance has not been corrected, the anticipated time it is expected to continue; and steps taken or planned to reduce, eliminate, and prevent reoccurrence of the noncompliance.

b. The following shall be included as information which must be reported within 24 hours under this subdivision:

(1) Any unanticipated bypass that exceeds any effluent limitation in the state permit.

(2) Any upset that exceeds any effluent limitation in the state permit.

(3) Violation of a maximum daily discharge limitation for any of the pollutants listed in the state permit to be reported within 24 hours.

c. The board may waive the written report on a case-by-case basis for reports under this subdivision if the oral report has been received within 24 hours.

8. The state permittee shall report all instances of noncompliance not reported under subdivisions 4, 5, 6, and 7 of this subsection, in writing at the time the next monitoring reports are submitted. The reports shall contain the information listed in subdivision 7 of this subsection.

9. Where the state permittee becomes aware that it failed to submit any relevant facts in a permit application, or submitted incorrect information in a state permit application or in any report to the department, it shall promptly submit such facts or information.

M. Bypass.

1. The state 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 subdivisions 2 and 3 of this subsection.

2. Notice.

a. Anticipated bypass. If the state permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least 10 days before the date of the bypass.

b. Unanticipated bypass. The state permittee shall submit notice of an unanticipated bypass as required in subdivision L 7 of this section (24-hour notice).

3. Prohibition of bypass.

a. Bypass is prohibited, and the board may take enforcement action against a state 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 state permittee submitted notices as required under subdivision 2 of this subsection.

b. The board may approve an anticipated bypass, after considering its adverse effects, if the board determines that it will meet the three conditions listed in subdivision 3 a of this subsection.

N. Upset.

1. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based state permit effluent limitations if the requirements of subdivision 2 of this subsection are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review.

2. A state 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 state permittee can identify the cause or causes of the upset;

b. The permitted facility was at the time being properly operated;

c. The state permittee submitted notice of the upset as required in subdivision L 7 b (2) of this section (24-hour notice); and

d. The state permittee complied with any remedial measures required under subsection D of this section.

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

4VAC50-60-440

4VAC50-60-440. Additional conditions applicable to Municipal Separate Storm Sewer System VSMP state permits.

In addition to those conditions set forth in 4VAC50-60-430, the operator of a large or medium municipal separate storm sewer system or a municipal separate storm sewer that has been designated by the board under 4VAC50-60-380 A 1 e must submit an annual report by a date specified in the state permit for such system. The report shall include:

1. The status of implementing the components of the stormwater management program that are established as state permit conditions;

2. Proposed changes to the stormwater management programs that are established as state permit condition conditions. Such proposed changes shall be consistent with 4VAC50-60-380 C 2 d;

3. Revisions, if necessary, to the assessment of controls and the fiscal analysis reported in the state permit application;

4. A summary of data, including monitoring data, that is accumulated throughout the reporting year;

5. Annual expenditures and budget for year following each annual report;

6. A summary describing the number and nature of enforcement actions, inspections, and public education programs; and

7. Identification of water quality improvements or degradation.

4VAC50-60-450

4VAC50-60-450. Establishing state permit conditions.

A. In addition to conditions required in all state permits, the board shall establish conditions, as required on a case-by-case basis, to provide for and assure compliance with all applicable requirements of the Stormwater Management Act, the State Water Control Law, the CWA, and attendant regulations. These shall include conditions under 4VAC50-60-480 (duration of state permits), 4VAC50-60-490 (schedules of compliance) and 4VAC50-60-460 (monitoring).

B. 1. An applicable requirement is a state statutory or regulatory requirement which takes effect prior to final administrative disposition of a state permit. An applicable requirement is also any requirement that takes effect prior to the modification or revocation and reissuance of a state permit to the extent allowed in Part X of this chapter.

2. New or reissued state permits, and to the extent allowed under Part X of this chapter modified or revoked and reissued state permits, shall incorporate each of the applicable requirements referenced in 4VAC50-60-460 and 4VAC50-60-470.

C. All state permit conditions shall be incorporated either expressly or by reference. If incorporated by reference, a specific citation to the applicable regulations or requirements must be given in the state permit.

4VAC50-60-460

4VAC50-60-460. Establishing limitations, standards, and other state permit conditions.

In addition to the conditions established under 4VAC50-60-450 A, each VSMP state permit shall include conditions meeting the following requirements when applicable.

A. 1. Technology-based effluent limitations and standards based on effluent limitations and standards promulgated under § 301 of the CWA, on new source performance standards promulgated under § 306 of CWA, on case-by-case effluent limitations determined under § 402(a)(1) of CWA, or a combination of the three. For new sources or new dischargers, these technology-based limitations and standards are subject to the provisions of 4VAC50-60-420 B (protection period).

2. The board may authorize a discharger subject to technology-based effluent limitations guidelines and standards in a VSMP state permit to forego sampling of a pollutant found at 40 CFR Subchapter N (2000) if the discharger has demonstrated through sampling and other technical factors that the pollutant is not present in the discharge or is present only at background levels from intake water and without any increase in the pollutant due to activities of the discharger. This waiver is good only for the term of the state permit and is not available during the term of the first state permit issued to a discharger. Any request for this waiver must be submitted when applying for a reissued state permit or modification of a reissued state permit. The request must demonstrate through sampling or other technical information, including information generated during an earlier state permit term, that the pollutant is not present in the discharge or is present only at background levels from intake water and without any increase in the pollutant due to activities of the discharger. Any grant of the monitoring waiver must be included in the state permit as an express state permit condition and the reasons supporting the grant must be documented in the state permit's fact sheet or statement of basis. This provision does not supersede certification processes and requirements already established in existing effluent limitations guidelines and standards.

B. Other effluent limitations and standards under §§ 301, 302, 303, 307, 318 and 405 of the CWA. If any applicable toxic effluent standard or prohibition (including any schedule of compliance specified in such effluent standard or prohibition) is promulgated under § 307(a) of the CWA for a toxic pollutant and that standard or prohibition is more stringent than any limitation on the pollutant in the state permit, the board shall institute proceedings under this chapter to modify or revoke and reissue the state permit to conform to the toxic effluent standard or prohibition.

C. Water quality standards and state requirements. Any requirements in addition to or more stringent than promulgated effluent limitations guidelines or standards under §§ 301, 304, 306, 307, 318 and 405 of the CWA necessary to:

1. Achieve water quality standards established under the State Water Control Law and § 303 of the CWA, including state narrative criteria for water quality.

a. Limitations must control all pollutants or pollutant parameters (either conventional, nonconventional, or toxic pollutants) which the board determines are or may be discharged at a level that will cause, have the reasonable potential to cause, or contribute to an excursion above any Virginia water quality standard, including Virginia narrative criteria for water quality.

b. When determining whether a discharge causes, has the reasonable potential to cause, or contributes to an in-stream excursion above a narrative or numeric criteria within a Virginia water quality standard, the board shall use procedures that account for existing controls on point and nonpoint sources of pollution, the variability of the pollutant or pollutant parameter in the effluent, the sensitivity of the species to toxicity testing (when evaluating whole effluent toxicity), and where appropriate, the dilution of the effluent in the receiving water.

c. When the board determines, using the procedures in subdivision 1 b of this subsection, that a discharge causes, has the reasonable potential to cause, or contributes to an in-stream excursion above the allowable ambient concentration of a Virginia numeric criteria within a Virginia water quality standard for an individual pollutant, the state permit must contain effluent limits for that pollutant.

d. Except as provided in this subdivision, when the board determines, using the procedures in subdivision 1 b of this subsection, toxicity testing data, or other information, that a discharge causes, has the reasonable potential to cause, or contributes to an in-stream excursion above a narrative criterion within an applicable Virginia water quality standard, the state permit must contain effluent limits for whole effluent toxicity. Limits on whole effluent toxicity are not necessary where the board demonstrates in the fact sheet or statement of basis of the VSMP state permit, using the procedures in subdivision 1 b of this subsection, that chemical-specific limits for the effluent are sufficient to attain and maintain applicable numeric and narrative Virginia water quality standards.

e. Where Virginia has not established a water quality criterion for a specific chemical pollutant that is present in an effluent at a concentration that causes, has the reasonable potential to cause, or contributes to an excursion above a narrative criterion within an applicable Virginia water quality standard, the board must establish effluent limits using one or more of the following options:

(1) Establish effluent limits using a calculated numeric water quality criterion for the pollutant which the board demonstrates will attain and maintain applicable narrative water quality criteria and will fully protect the designated use. Such a criterion may be derived using a proposed Virginia criterion, or an explicit policy or regulation interpreting Virginia's narrative water quality criterion, supplemented with other relevant information which may include: EPA's Water Quality Standards Handbook, August 1994, risk assessment data, exposure data, information about the pollutant from the Food and Drug Administration, and current EPA criteria documents; or

(2) Establish effluent limits on a case-by-case basis, using EPA's water quality criteria, published under § 307(a) of the CWA, supplemented where necessary by other relevant information; or

(3) Establish effluent limitations on an indicator parameter for the pollutant of concern, provided:

(a) The state permit identifies which pollutants are intended to be controlled by the use of the effluent limitation;

(b) The fact sheet required by 4VAC50-60-520 sets forth the basis for the limit, including a finding that compliance with the effluent limit on the indicator parameter will result in controls on the pollutant of concern which are sufficient to attain and maintain applicable water quality standards;

(c) The state permit requires all effluent and ambient monitoring necessary to show that during the term of the state permit the limit on the indicator parameter continues to attain and maintain applicable water quality standards; and

(d) The state permit contains a reopener clause allowing the board to modify or revoke and reissue the state permit if the limits on the indicator parameter no longer attain and maintain applicable water quality standards.

f. When developing water quality-based effluent limits under this subdivision the board shall ensure that:

(1) The level of water quality to be achieved by limits on point sources established under this subsection is derived from, and complies with all applicable water quality standards; and

(2) Effluent limits developed to protect a narrative water quality criterion, a numeric water quality criterion, or both, are consistent with the assumptions and requirements of any available wasteload allocation for the discharge prepared by Virginia and approved by EPA pursuant to 40 CFR 130.7 (2000);

2. Attain or maintain a specified water quality through water quality related effluent limits established under the State Water Control Law and § 302 of the CWA;

3. Conform to the conditions of a Virginia Water Protection Permit (VWPP) issued under the State Water Control Law and § 401 of the CWA;

4. Conform to applicable water quality requirements under § 401(a)(2) of the CWA when the discharge affects a state other than Virginia;

5. Incorporate any more stringent limitations, treatment standards, or schedule of compliance requirements established under the Act or regulations in accordance with § 301(b)(1)(C) of the CWA;

6. Ensure consistency with the requirements of a Water Quality Management plan established by the State Water Control Board pursuant to 9VAC25-720 and approved by EPA under § 208(b) of the CWA;

7. Incorporate § 403(c) criteria under 40 CFR Part 125, Subpart M (2000), for ocean discharges; or

8. Incorporate alternative effluent limitations or standards where warranted by fundamentally different factors, under 40 CFR Part 125, Subpart D (2000).

D. Technology-based controls for toxic pollutants. Limitations established under subsections A, B, or C of this section, to control pollutants meeting the criteria listed in subdivision 1 of this subsection. Limitations will be established in accordance with subdivision 2 of this subsection. An explanation of the development of these limitations shall be included in the fact sheet.

1. Limitations must control all toxic pollutants that the board determines (based on information reported in a permit application or in a notification required by the state permit or on other information) are or may be discharged at a level greater than the level that can be achieved by the technology-based treatment requirements appropriate to the state permittee; or

2. The requirement that the limitations control the pollutants meeting the criteria of subdivision 1 of this subsection will be satisfied by:

a. Limitations on those pollutants; or

b. Limitations on other pollutants that, in the judgment of the board, will provide treatment of the pollutants under subdivision 1 of this subsection to the levels required by the Stormwater Management Act, the State Water Control Law, and 40 CFR Part 125, Subpart A (2000).

E. A notification level that exceeds the notification level of 4VAC50-60-440 A 1 a, b, or c, upon a petition from the state permittee or on the board's initiative. This new notification level may not exceed the level which can be achieved by the technology-based treatment requirements appropriate to the state permittee.

F. Twenty-four-hour reporting. Pollutants for which the state permittee must report violations of maximum daily discharge limitations under 4VAC50-60-430 L 7 b (3) (24-hour reporting) shall be listed in the state permit. This list shall include any toxic pollutant or hazardous substance, or any pollutant specifically identified as the method to control a toxic pollutant or hazardous substance.

G. Durations for state permits, as set forth in 4VAC50-60-480.

H. Monitoring requirements. The following monitoring requirements:

1. Requirements concerning the proper use, maintenance, and installation, when appropriate, of monitoring equipment or methods (including biological monitoring methods when appropriate);

2. Required monitoring including type, intervals, and frequency sufficient to yield data that are representative of the monitored activity including, when appropriate, continuous monitoring;

3. Applicable reporting requirements based upon the impact of the regulated activity and as specified in 4VAC50-60-430 and in subdivisions 5 through 8 of this subsection. Reporting shall be no less frequent than specified in the above regulation;

4. To assure compliance with state permit limitations, requirements to monitor:

a. The mass (or other measurement specified in the state permit) for each pollutant limited in the state permit;

b. The volume of effluent discharged from each outfall;

c. Other measurements as appropriate including pollutants; frequency, rate of discharge, etc., for noncontinuous discharges; pollutants subject to notification requirements; or as determined to be necessary on a case-by-case basis pursuant to the Stormwater Management Act, the State Water Control Law, and § 405(d)(4) of the CWA; and

d. According to test procedures approved under 40 CFR Part 136 (2000) for the analyses of pollutants having approved methods under that part, or alternative EPA approved methods, and according to a test procedure specified in the state permit for pollutants with no approved methods;

5. Except as provided in subdivisions 7 and 8 of this subsection, requirements to report monitoring results shall be established on a case-by-case basis with a frequency dependent on the nature and effect of the discharge, but in no case less that once a year;

6. Requirements to report monitoring results for stormwater discharges associated with industrial activity that are subject to an effluent limitation guideline shall be established on a case-by-case basis with a frequency dependent on the nature and effect of the discharge, but in no case less than once a year;

7. Requirements to report monitoring results for stormwater discharges (other than those addressed in subdivision 6 of this subsection) shall be established on a case-by-case basis with a frequency dependent on the nature and effect of the discharge. At a minimum, a state permit for such a discharge must require:

a. The discharger to conduct an annual inspection of the facility site to identify areas contributing to a stormwater discharge and evaluate whether measures to reduce pollutant loading identified in a stormwater pollution prevention plan are adequate and properly implemented in accordance with the terms of the state permit or whether additional control measures are needed;

b. The discharger to maintain for a period of three years a record summarizing the results of the inspection and a certification that the facility is in compliance with the plan and the state permit, and identifying any incidents of noncompliance;

c. Such report and certification be signed in accordance with 4VAC50-60-370; and

8. Permits State permits which do not require the submittal of monitoring result reports at least annually shall require that the state permittee report all instances of noncompliance not reported under 4VAC50-60-430 L 1, 4, 5, 6, and 7 at least annually.

I. Best management practices to control or abate the discharge of pollutants when:

1. Authorized under § 402(p) of the CWA for the control of stormwater discharges;

2. Numeric effluent limitations are infeasible; or

3. The practices are reasonably necessary to achieve effluent limitations and standards or to carry out the purposes and intent of the Stormwater Management Act, the State Water Control Law, and the CWA.

J. Reissued state permits.

1. In the case of effluent limitations established on the basis of § 402(a)(1)(B) of the CWA, a state permit may not be renewed, reissued, or modified on the basis of effluent guidelines promulgated under § 304(b) of the CWA subsequent to the original issuance of such state permit, to contain effluent limitations that are less stringent than the comparable effluent limitations in the previous state permit. In the case of effluent limitations established on the basis of § 301(b)(1)(C) or § 303(d) or (e) of the CWA, a state permit may not be renewed, reissued, or modified to contain effluent limitations that are less stringent than the comparable effluent limitations in the previous state permit except in compliance with § 303(d)(4) of the CWA.

2. Exceptions. A state permit with respect to which subdivision 1 of this subsection applies may be renewed, reissued, or modified to contain a less stringent effluent limitation applicable to a pollutant, if:

a. Material and substantial alterations or additions to the permitted facility occurred after permit issuance that justify the application of a less stringent effluent limitation;

b. (1) Information is available that was not available at the time of state permit issuance (other than revised regulations, guidance, or test methods) and that would have justified the application of a less stringent effluent limitation at the time of state permit issuance; or

(2) The board determines that technical mistakes or mistaken interpretations of the Act were made in issuing the state permit under § 402(a)(1)(B) of the CWA;

c. A less stringent effluent limitation is necessary because of events over which the state permittee has no control and for which there is no reasonably available remedy;

d. The state permittee has received a state permit modification under the Stormwater Management Act, the State Water Control Law, and §§ 301(c), 301(g), 301(h), 301(i), 301(k), 301(n), or § 316(a) of the CWA; or

e. The state permittee has installed the treatment facilities required to meet the effluent limitations in the previous state permit and has properly operated and maintained the facilities but has nevertheless been unable to achieve the previous effluent limitations, in which case the limitations in the reviewed, reissued, or modified state permit may reflect the level of pollutant control actually achieved (but shall not be less stringent than required by effluent guidelines in effect at the time of state permit renewal, reissuance, or modification).

Subdivision 2 b of this subsection shall not apply to any revised waste load allocations or any alternative grounds for translating water quality standards into effluent limitations, except where the cumulative effect of such revised allocations results in a decrease in the amount of pollutants discharged into the concerned waters, and such revised allocations are not the result of a discharger eliminating or substantially reducing its discharge of pollutants due to complying with the requirements of the Act or the CWA or for reasons otherwise unrelated to water quality.

3. In no event may a state permit with respect to which subdivision 2 of this subsection applies be renewed, reissued, or modified to contain an effluent limitation that is less stringent than required by effluent guidelines in effect at the time the state permit is renewed, reissued, or modified. In no event may such a state permit to discharge into waters be renewed, issued, or modified to contain a less stringent effluent limitation if the implementation of such limitation would result in a violation of a Virginia water quality standard applicable to such waters.

K. Navigation. Any conditions that the Secretary of the Army considers necessary to ensure that navigation and anchorage will not be substantially impaired in accordance with 4VAC50-60-570.

L. Qualifying state, tribal, or local programs.

1. For stormwater discharges associated with small construction activity identified in 4VAC50-60-10, the board may include state permit conditions that incorporate qualifying state, tribal, or local erosion and sediment control program requirements by reference. Where a qualifying state, tribal, or local program does not include one or more of the elements in this subdivision, then the board must include those elements as conditions in the state permit. A qualifying state, tribal, or local erosion and sediment control program is one that includes:

a. Requirements for construction site operators to implement appropriate erosion and sediment control best management practices;

b. Requirements for construction site operators to control waste such as discarded building materials, concrete truck washout, chemicals, litter, and sanitary waste at the construction site that may cause adverse impacts to water quality;

c. Requirements for construction site operators to develop and implement a stormwater pollution prevention plan. A stormwater pollution prevention plan includes site descriptions; descriptions of appropriate control measures; copies of approved state, tribal or local requirements; maintenance procedures; inspection procedures; and identification of nonstormwater discharges; and

d. Requirements to submit a site plan for review that incorporates consideration of potential water quality impacts.

2. For stormwater discharges from construction activity that does not meet the definition of a small construction activity, the board may include state permit conditions that incorporate qualifying state, tribal, or local erosion and sediment control program requirements by reference. A qualifying state, tribal or local erosion and sediment control program is one that includes the elements listed in subdivision 1 of this subsection and any additional requirements necessary to achieve the applicable technology-based standards of "best available technology" and "best conventional technology" based on the best professional judgment of the state permit writer.

4VAC50-60-470

4VAC50-60-470. Calculating VSMP state permit conditions.

A. Permit State permit effluent limitations, monitoring requirements, standards and prohibitions shall be established for each outfall or discharge point of the permitted facility, except as otherwise provided under 4VAC50-60-460.

B. All state permit effluent limitations, standards, or prohibitions for a metal shall be expressed in terms of total recoverable metal as defined in 40 CFR Part 136 (2000) unless:

1. An applicable effluent standard or limitation has been promulgated under the CWA and specifies the limitation for the metal in the dissolved or valent or total form; or

2. In establishing state permit limitations on a case-by-case basis under 40 CFR 125.3 (2000), it is necessary to express the limitation on the metal in the dissolved or valent or total form to carry out the provisions of the CWA, Stormwater Management Act and the State Water Control Law; or

3. All approved analytical methods for the metal inherently measure only its dissolved form (e.g., hexavalent chromium).

C. Discharges that are not continuous, as defined in 4VAC50-60-10, shall be particularly described and limited, considering the following factors, as appropriate:

1. Frequency;

2. Total mass;

3. Maximum rate of discharge of pollutants during the discharge; and

4. Prohibition or limitation of specified pollutants by mass, concentration, or other appropriate measure.

D. Mass Limitations.

1. All pollutants limited in state permits shall have limitations, standards or prohibitions expressed in terms of mass except:

a. For pH, temperature, radiation, or other pollutants that cannot appropriately be expressed by mass;

b. When applicable standards and limitations are expressed in terms of other units of measurement; or

c. If in establishing technology-based state permit limitations on a case-by-case basis, limitations expressed in terms of mass are infeasible because the mass of the pollutant discharged cannot be related to a measure of operation (for example, discharges of TSS from certain mining operations), and state permit conditions ensure that dilution will not be used as a substitute for treatment.

2. Pollutants limited in terms of mass additionally may be limited in terms of other units of measurement, and the state permit shall require the state permittee to comply with both limitations.

4VAC50-60-480

4VAC50-60-480. Duration of state permits.

A. VSMP State permits shall be effective for a fixed term not to exceed five years.

B. Except as provided in 4VAC50-60-330, the term of a state permit shall not be extended by modification beyond the maximum duration specified in this section.

C. The board may issue any state permit for a duration that is less than the full allowable term under this section.

D. A state permit may be issued to expire on or after the statutory deadline set forth in §§ 301(b)(2) (A), (C), and (E) of the CWA, if the state permit includes effluent limitations to meet the requirements of §§ 301(b)(2) (A), (C), (D), (E) and (F) of the CWA, whether or not applicable effluent limitations guidelines have been promulgated or approved.

4VAC50-60-490

4VAC50-60-490. Schedules of compliance.

A. The state permit may, when appropriate, specify a schedule of compliance leading to compliance with the Act, the CWA and regulations.

1. Any schedules of compliance under this section shall require compliance as soon as possible, but not later than the applicable statutory deadline under the CWA.

2. The first VSMP state permit issued to a new source or a new discharger shall contain a schedule of compliance only when necessary to allow a reasonable opportunity to attain compliance with requirements issued or revised after commencement of construction but less than three years before commencement of the relevant discharge. For recommencing dischargers, a schedule of compliance shall be available only when necessary to allow a reasonable opportunity to attain compliance with requirements issued or revised less than three years before recommencement of discharge.

3. Schedules of compliance may be established in state permits for existing sources that are reissued or modified to contain new or more restrictive water quality-based effluent limitations. The schedule may allow a reasonable period of time, not to exceed the term of the state permit, for the discharger to attain compliance with the water quality-based limitations.

4. Except as provided in subdivision B 1 b of this section, if a state permit establishes a schedule of compliance that exceeds one year from the date of state permit issuance, the schedule shall set forth interim requirements and the dates for their achievement.

a. The time between interim dates shall not exceed one year.

b. If the time necessary for completion of any interim requirement is more than one year and is not readily divisible into stages for completion, the state permit shall specify interim dates for the submission of reports of progress toward completion of the interim requirements and indicate a projected completion date.

5. The state permit shall be written to require that no later than 14 days following each interim date and the final date of compliance, the state permittee shall notify the department in writing of its compliance or noncompliance with the interim or final requirements, or submit progress reports if subdivision 4 b of this subsection is applicable.

B. A VSMP state permit applicant or state permittee may cease conducting regulated activities (by terminating of direct discharge for VSMP sources) rather than continuing to operate and meet state permit requirements as follows:

1. If the state permittee decides to cease conducting regulated activities at a given time within the term of a state permit that has already been issued:

a. The state permit may be modified to contain a new or additional schedule leading to timely cessation of activities; or

b. The state permittee shall cease conducting permitted activities before noncompliance with any interim or final compliance schedule requirement already specified in the state permit;

2. If the decision to cease conducting regulated activities is made before issuance of a state permit whose term will include the termination date, the state permit shall contain a schedule leading to termination which will ensure timely compliance with applicable requirements no later than the statutory deadline;

3. If the state permittee is undecided whether to cease conducting regulated activities, the board may issue or modify a state permit to contain two schedules as follows:

a. Both schedules shall contain an identical interim deadline requiring a final decision on whether to cease conducting regulated activities no later than a date that ensures sufficient time to comply with applicable requirements in a timely manner if the decision is to continue conducting regulated activities;

b. One schedule shall lead to timely compliance with applicable requirements no later than the statutory deadline;

c. The second schedule shall lead to cessation of regulated activities by a date that will ensure timely compliance with applicable requirements no later than the statutory deadline; and

d. Each state permit containing two schedules shall include a requirement that after the state permittee has made a final decision under subdivision 3 a of this subsection it shall follow the schedule leading to compliance if the decision is to continue conducting regulated activities, and follow the schedule leading to termination if the decision is to cease conducting regulated activities; and

4. The state permit applicant's or state permittee's decision to cease conducting regulated activities shall be evidenced by a firm public commitment satisfactory to the board, such as a resolution of the board of directors of a corporation.

4VAC50-60-570

4VAC50-60-570. Conditions requested by the Corps of Engineers and other government agencies.

A. If during the comment period for an VSMP a draft state permit, the district engineer advises the department in writing that anchorage and navigation of any of the waters of the United States would be substantially impaired by the granting of a state permit, the state permit shall be denied and the state permit applicant so notified. If the district engineer advised the department that imposing specified conditions upon the state permit is necessary to avoid any substantial impairment of anchorage or navigation, then the board shall include the specified conditions in the state permit. Review or appeal of denial of a state permit or of conditions specified by the district engineer shall be made through the applicable procedures of the Corps of Engineers, and may not be made through the procedures provided in this part. If the conditions are stayed by a court of competent jurisdiction or by applicable procedures of the Corps of Engineers, those conditions shall be considered stayed in the VSMP state permit for the duration of that stay.

B. If during the comment period the U.S. Fish and Wildlife Service, the National Marine Fisheries Service, or any other state or federal agency with jurisdiction over fish, wildlife, or public health advises the department in writing that the imposition of specified conditions upon the state permit is necessary to avoid substantial impairment of fish, shellfish, or wildlife resources, the board may include the specified conditions in the state permit to the extent they are determined necessary to carry out the provisions of this regulation, the Act and of the CWA.

C. In appropriate cases the board may consult with one or more of the agencies referred to in this section before issuing a draft state permit and may reflect their views in the statement of basis, the fact sheet, or the draft state permit.

1. A variance based on the economic capability of the state permit applicant submitted pursuant to 4VAC50-60-360 G 2; or

2. A variance based on water quality related effluent limitations submitted pursuant to 4VAC50-60-360 G 3.

C. If the EPA approves the variance, the board may prepare a draft state permit incorporating the variance. Any public notice of a draft state permit for which a variance or modification has been approved or denied shall identify the applicable procedures for appealing that decision.

D. The board may deny or forward to the administrator with a written concurrence a completed request for:

1. A variance based on the presence of fundamentally different factors from those on which an effluent limitations guideline was based, made according to the criteria and standards of 40 CFR Part 125, Subpart D (2000); or

2. A variance based upon certain water quality factors submitted pursuant to 4VAC50-60-360 G 2.

E. If the administrator approves the variance, the board may prepare a draft state permit incorporating the variance. Any public notice of a draft state permit for which a variance or modification has been approved or denied shall identify the applicable procedures for appealing that decision.

4VAC50-60-590

Part X
Transfer, Modification, Revocation and Reissuance, and Termination of VSMP State Permits

4VAC50-60-610. Modification, revocation and reissuance, or termination of state permits.

A. Permits State permits may be modified, revoked and reissued, or terminated either at the request of any interested person (including the state permittee) or upon the board's initiative. When the department receives any information (for example, inspects the facility, receives information submitted by the state permittee as required in the state permit, receives a request for modification or revocation and reissuance, or conducts a review of the state permit file) it may determine whether one or more of the causes listed in this section for modification or revocation and reissuance, or both, exist. However, state permits may only be modified, revoked and reissued, or terminated for the reasons specified in 4VAC50-60-630 or 4VAC50-60-650. All requests shall be in writing and shall contain facts or reasons supporting the request. If cause does not exist under these sections, the board shall not modify, revoke and reissue or terminate the state permit. If a state permit modification satisfies the criteria for minor modifications, the state permit may be modified without a draft state permit or public review. Otherwise, a draft state permit must be prepared and other procedures in Part IX (4VAC50-60-500 et seq.) followed.

B. If the board decides the request is not justified, it shall send the requester a brief written response giving a reason for the decision. Denials of requests for modification, revocation and reissuance, or termination are not subject to public notice, comment, or public hearings.

C. 1. If the board tentatively decides to modify or revoke and reissue a state permit, it shall prepare a draft state permit incorporating the proposed changes. The board may request additional information and, in the case of a modified state permit, may require the submission of an updated application. In the case of revoked and reissued state permits, the board shall require the submission of a new application.

2. In a state permit modification under this section, only those conditions to be modified shall be reopened when a new draft state permit is prepared. All other aspects of the existing state permit shall remain in effect for the duration of the unmodified state permit. When a state permit is revoked and reissued under this section, the entire state permit is reopened just as if the state permit had expired and was being reissued and the state permit is reissued for a new term. During any revocation and reissuance proceeding the state permittee shall comply with all conditions of the existing state permit until a new final state permit is reissued.

3. Minor modifications as defined in 4VAC50-60-640 are not subject to the requirements of this section.

D. If the board tentatively decides to terminate a state permit under 4VAC50-60-650, where the state permittee objects, it shall issue a notice of intent to terminate. A notice of intent to terminate is a type of draft state permit that follows the same procedures as any draft state permit.

4VAC50-60-620

4VAC50-60-620. Transfer of state permits.

A. Except as provided in subsection B of this section, a state permit may be transferred by the state permittee to a new owner or operator only if the state permit has been modified or revoked and reissued, or a minor modification made, to identify the new state permittee and incorporate such other requirements as may be necessary under the Virginia Stormwater Management Act and the CWA.

B. Automatic transfers. As an alternative to transfers under subsection A of this section, any VSMP state permit may be automatically transferred to a new state permittee if:

1. The current state permittee notifies the department at least 30 days in advance of the proposed transfer date in subdivision 2 of this subsection;

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

3. The board does not notify the existing state permittee and the proposed new state permittee of its intent to modify or revoke and reissue the state permit. A modification under this subdivision may also be a minor modification. If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in subdivision 2 of this subsection.

4VAC50-60-630

4VAC50-60-630. Modification or revocation and reissuance of state permits.

A. Causes for modification. The following are causes for modification but not revocation and reissuance of state permits except when the state permittee requests or agrees.

1. There are material and substantial alterations or additions to the permitted facility or activity that occurred after state permit issuance that justify the application of state permit conditions that are different or absent in the existing state permit.

2. The department has received new information. Permits State permits may be modified during their terms for this cause only if the information was not available at the time of state permit issuance (other than revised regulations, guidance, or test methods) and would have justified the application of different state permit conditions at the time of issuance. For VSMP general permits this cause includes any information indicating that cumulative effects on the environment are unacceptable. For new source or new discharger VSMP state permits this cause shall include any significant information derived from effluent testing required on the state permit application after issuance of the state permit.

3. The standards or regulations on which the state permit was based have been changed by promulgation of amended standards or regulations or by judicial decision after the state permit was issued. Permits State permits may be modified during their terms for this cause only as follows:

a. For promulgation of amended standards or regulations, when:

(1) The state permit condition requested to be modified was based on a promulgated effluent limitation guideline, EPA approved or promulgated water quality standards;

(2) EPA has revised, withdrawn, or modified that portion of the regulation or effluent limitation guideline on which the state permit condition was based, or has approved a state action with regard to a water quality standard on which the state permit condition was based; and

(3) A state permittee requests modification in accordance with this chapter within 90 days after Federal Register notice of the action on which the request is based;

b. For judicial decisions, a court of competent jurisdiction has remanded and stayed EPA promulgated regulations or effluent limitation guidelines, if the remand and stay concern that portion of the regulations or guidelines on which the state permit condition was based and a request is filed by the state permittee in accordance with this chapter within 90 days of judicial remand; or

c. For changes based upon modified state certifications of VSMP state permits.

4. The board determines good cause exists for modification of a compliance schedule, such as an act of God, strike, flood, or materials shortage or other events over which the state permittee has little or no control and for which there is no reasonably available remedy. However, in no case may a VSMP compliance schedule be modified to extend beyond an applicable CWA statutory deadline.

5. When the state permittee has filed a request for a variance pursuant to 4VAC50-60-360 G within the time specified in this chapter.

6. When required to incorporate an applicable CWA § 307(a) toxic effluent standard or prohibition.

7. When required by the reopener conditions in a state permit that are established under 4VAC50-60-460 B.

8. Upon failure to notify another state whose waters may be affected by a discharge.

9. When the level of discharge of any pollutant that is not limited in the state permit exceeds the level that can be achieved by the technology-based treatment requirements appropriate to the state permittee.

10. To establish a notification level as provided in 4VAC50-60-460 E.

11. To correct technical mistakes, such as errors in calculation, or mistaken interpretations of law made in determining state permit conditions.

12. When the discharger has installed the treatment technology considered by the state permit writer in setting effluent limitations imposed under the Act and § 402(a)(1) of the CWA and has properly operated and maintained the facilities but nevertheless has been unable to achieve those effluent limitations. In this case, the limitations in the modified state permit may reflect the level of pollutant control actually achieved (but shall not be less stringent than required by a subsequently promulgated effluent limitations guideline).

13. For a small MS4, to include an effluent limitation requiring implementation of a minimum control measure or measures as specified in 4VAC50-60-400 D 2 when:

a. The state permit does not include such measures based upon the determination that another entity was responsible for implementation of the requirements; and

b. The other entity fails to implement measures that satisfy the requirements.

B. Causes for modification or revocation and reissuance. The following are causes to modify or, alternatively, revoke and reissue a state permit:

1. Cause exists for termination under 4VAC50-60-650, and the board determines that modification or revocation and reissuance is appropriate; or

2. The department has received notification of a proposed transfer of the state permit. A state permit also may be modified to reflect a transfer after the effective date of an automatic transfer but will not be revoked and reissued after the effective date of the transfer except upon the request of the new state permittee.

4VAC50-60-640

4VAC50-60-640. Minor modifications of state permits.

Upon the consent of the state permittee, the board may modify a state permit to make the corrections or allowances for changes in the permitted activity listed in this section, without following the procedures of Part IX of this chapter. Any state permit modification not processed as a minor modification under this section must be made for cause and with draft state permit and public notice. Minor modifications may only:

1. Correct typographical errors;

2. Require more frequent monitoring or reporting by the state permittee;

3. Change an interim compliance date in a schedule of compliance, provided the new date is not more than 120 days after the date specified in the existing state permit and does not interfere with attainment of the final compliance date requirement;

4. Allow for a change in ownership or operational control of a facility where the board determines that no other change in the state permit is necessary, provided that a written agreement containing a specific date for transfer of state permit responsibility, coverage, and liability between the current and new state permittees has been submitted to the department;

5. a. Change the construction schedule for a discharger which is a new source. No such change shall affect a discharger's obligation to have all pollution control equipment installed and in operation prior to discharge.

b. Delete a point source outfall when the discharge from that outfall is terminated and does not result in discharge of pollutants from other outfalls except in accordance with state permit limits.

4VAC50-60-650

4VAC50-60-650. Termination of state permits.

A. The following are causes for terminating a state permit during its term, or for denying a state permit renewal application, after public notice and opportunity for a public hearing by the board.

1. The state permittee has violated any regulation or order of the board or department, any order of the permit-issuing VSMP authority, any provision of the Virginia Stormwater Management Act or this chapter, or any order of a court, where such violation results in the unreasonable degradation of properties, water quality, stream channels, and other natural resources, or the violation is representative of a pattern of serious or repeated violations that in the opinion of the board, demonstrates the state permittee's disregard for or inability to comply with applicable laws, regulations, state permit conditions, orders, rules, or requirements;

2. Noncompliance by the state permittee with any condition of the state permit;

3. The state permittee's failure to disclose fully all relevant material facts, or the state permittee's misrepresentation of any relevant material facts in applying for a state permit, or in any other report or document required under the Act or this chapter;

4. A determination that the permitted activity endangers human health or the environment and can only be regulated to acceptable levels by state permit modification or termination;

5. A change in any condition that requires either a temporary or permanent reduction or elimination of any discharge controlled by the state permit; or

6. The activity for which the state permit was issued causes unreasonable degradation of properties, water quality, stream channels, and other natural resources

7. There exists a material change in the basis on which the state permit was issued that requires either a temporary or a permanent reduction or elimination of any discharge or land-disturbing activity controlled by the state permit necessary to prevent unreasonable degradation of properties, water quality, stream channels, and other natural resources.

B. The board shall follow the applicable procedures in this chapter in terminating any VSMP state permit under this section, except that if the entire discharge is permanently terminated by elimination of the flow or by connection to a POTW or a PVOTW (but not by land application or disposal into a well), the board may terminate the state permit by notice to the state permittee. Termination by notice shall be effective 30 days after notice is sent, unless the state permittee objects within that time. If the state permittee objects during that period, the board shall follow the applicable procedures for termination under 4VAC50-60-610 D. Expedited state permit termination procedures are not available to state permittees that are subject to pending state or federal enforcement actions including citizen suits brought under state or federal law. If requesting expedited state permit termination procedures, a state permittee must certify that it is not subject to any pending state or federal enforcement actions including citizen suits brought under state or federal law.

4VAC50-60-660

Part XI
Enforcement of VSMP State Permits

4VAC50-60-660. Enforcement.

A. The board may enforce the provisions of this chapter by:

1. Issuing directives in accordance with the Act;

2. Issuing special orders in accordance with the Act;

3. Issuing emergency special orders in accordance with the Act;

4. Seeking injunction, mandamus or other appropriate remedy as authorized by the Act;

5. Seeking civil penalties under the Act; or

6. Seeking remedies under the Act, the CWA or under other laws including the common law.

B. The board encourages citizen participation in all its activities, including enforcement. In particular:

1. The board will investigate citizen complaints and provide written response to all signed, written complaints from citizens concerning matters within the board's purview;

2. The board will not oppose intervention in any civil enforcement action when such intervention is authorized by statute or Supreme Court rule; and

3. At least 30 days prior to the final settlement of any civil enforcement action or the issuance of any consent special order, the board will publish public notice of such settlement or order in a newspaper of general circulation in the county, city or town in which the discharge is located, and in The Virginia Register of Regulations. This notice will identify the owner, specify the enforcement action to be taken and specify where a copy of the settlement or order can be obtained. A consent special order is a special order issued without a public hearing and with the written consent of the affected owner. For the purpose of this chapter, an emergency special order is not a consent special order. The board shall consider all comments received during the comment period before taking final action.

C. When a state permit is amended solely to reflect a new owner, and the previous owner had been issued a consent special order that, at the time of state permit amendment was still in full force and effect, a consent special order issued to the new owner does not have to go to public notice provided that:

a. The state permit amendment does not have to go to public notice; and

b. The terms of the new consent order are the same as issued to the previous owner.

D. Notwithstanding subdivision B 3 of this subsection, a special order may be issued by agreement at a board meeting without further notice when a public hearing has been scheduled to issue a special order to the affected owner, whether or not the public hearing is actually held.

4VAC50-60-680

4VAC50-60-680. Transition.

Upon the effective date of this chapter the following will occur:

1. All applications received after the effective date of this chapter will be processed in accordance with these procedures.

2. A National Pollutant Discharge Elimination System Permit issued by the board has the same effect as a VSMP state permit.

3. Permits State permits issued by the State Water Control Board allowing the discharge of stormwater into state waters from Municipal Separate Storm Sewer Systems or land-disturbing activities that have not expired or been revoked or terminated before or on the program transfer date to the board shall continue to remain in effect until their specified expiration dates.

4VAC50-60-700

Part XIII
Fees

4VAC50-60-700. Purpose.

Sections 10.1-603.4 and 10.1-603.5 of the Code of Virginia authorize the establishment of a statewide fee schedule, including administrative charges for state agencies, for stormwater management for land-disturbing activities and for municipal separate storm sewer systems. This part establishes the fee assessment and the collection and distribution systems for those fees. The fees associated with shall be established for individual permits or coverage under the General Permit for Discharges of Stormwater From Construction Activities (permits for stormwater management for land-disturbing activities) issued by a qualifying local program or a department-administered local stormwater management program (state permits for stormwater management for land-disturbing activities) to cover all costs associated with the implementation of a VSMP by a VSMP authority that has been approved by the board shall include and by the department. Such fee attributes include the costs associated with plan review, registration statement review, permit review and issuance, state-coverage verification, inspections, enforcement, program administration and oversight, and reporting, database management, and compliance activities associated with the land-disturbing activities as well as for program oversight costs. Fees shall also be established for state permit maintenance, modification, and transfer.

Fees collected pursuant to this part shall be in addition to any general fund appropriations made to the department or other supporting revenue from a VSMP; however, the fees shall be set at a level sufficient for the department and the VSMP authority to fully carry out their responsibilities under the Act, this chapter, local ordinances, or standards and specifications where applicable.

Should When establishing a VSMP, the VSMP authority shall assess the statewide fee schedule and shall have the authority to reduce or increase such fees, and to consolidate such fees with other program-related charges, but in no case shall such fee changes affect the amount established in 4VAC50-60-820 as available to the department for program oversight responsibilities pursuant to § 10.1-603.4 A 5 a of the Code of Virginia. Accordingly, should a qualifying local program VSMP authority demonstrate to the board its ability to fully and successfully implement a qualifying local program VSMP without a full implementation of the fees set out in this part, the board may authorize the administrative establishment of a lower fee for that program provided that such reduction shall not reduce the amount of fees due to the department for its program oversight and shall not affect the fee schedules set forth herein.

A qualifying local program VSMP authority may establish greater fees than those base fees specified by this part should it be demonstrated to the board that such greater fees are necessary to properly administer the qualifying local program VSMP. Any fee increases established by the qualifying local program VSMP authority beyond those base fees established in this part shall not be subject to the fee distribution formula set out in 4VAC50-60-780. Nothing in this part shall prohibit a locality from establishing other local fees authorized by the Code of Virginia related to stormwater management within their jurisdictions.

A VSMP's portion of the fees shall be used solely to carry out the VSMP's responsibilities under the Act, this chapter, ordinances, or annual standards and specifications.

As part of its program oversight, the department shall periodically assess the revenue generated by both the localities VSMP authorities and the department to ensure that the fees have been appropriately set and the fees may be adjusted through periodic regulatory actions should significant deviations become apparent.

Part XIV
General Virginia Stormwater Management Program (VSMP) Permit for Discharges of Stormwater from Construction Activities

4VAC50-60-1100. Definitions.

The words and terms used in this part shall have the meanings defined in the Act and this chapter unless the context clearly indicates otherwise, except as otherwise specified in this section. Terms not defined in the Act, this chapter, or this section shall have the meaning attributed to them in the CWA. For the purposes of this part:

"Commencement of construction" means the initial disturbance of soils associated with clearing, grading, or excavating activities or other construction activities (e.g., stockpiling of fill material).

"Final stabilization" means that one of the following situations has occurred:

1. All soil disturbing activities at the site have been completed and a permanent vegetative cover has been established on denuded areas not otherwise permanently stabilized. Permanent vegetation shall not be considered established until a ground cover is achieved that is uniform (e.g., evenly distributed ), mature enough to survive, and will inhibit erosion.

2. For individual lots in residential construction, final stabilization can occur by either:

a. The homebuilder completing final stabilization as specified in subdivision 1 of this definition; or

b. The homebuilder establishing temporary stabilization, including perimeter controls for an individual lot prior to occupation of the home by the homeowner, and informing the homeowner of the need for, and benefits of, final stabilization.

3. For construction projects on land used for agricultural purposes (e.g., pipelines across crop or range land), final stabilization may be accomplished by returning the disturbed land to its preconstruction agricultural use. Areas disturbed that were not previously used for agricultural activities, such as buffer strips immediately adjacent to surface waters, and areas that are not being returned to their preconstruction agricultural use must meet the final stabilization criteria specified in subdivision 1 or 2 of this definition.

"Minimize" means to prevent, reduce, or eliminate using practicable control measures to meet the conditions of this state permit.

4VAC50-60-1110

4VAC50-60-1110. Purpose.

This general permit regulation authorizes stormwater discharges from regulated construction activities. For the purposes of this part, these discharges are defined as stormwater discharges associated with large construction activity, and stormwater discharges associated with small construction activity. Stormwater discharges associated with other types of industrial activity shall not have coverage under this general permit. This general permit covers only discharges through a point source to state waters or through a municipal or nonmunicipal separate storm sewer system to state waters. Stormwater discharges associated with industrial activity that originate from the site after construction activities have been completed and the site has undergone final stabilization are not authorized by this state permit. The goal of this state permit is to minimize the discharge of stormwater pollutants from construction activity by requiring that the operator plan and implement appropriate control measures.

4VAC50-60-1130

4VAC50-60-1130. Authorization to discharge.

A. Any operator governed by this general permit is authorized to discharge to state waters of the Commonwealth of Virginia in accordance with 4VAC50-60-1150 A 4 provided that the operator has filed a complete and accurate registration statement in accordance with 4VAC50-60-1150, submitted any fees required by 4VAC50-60-700 et seq. (Part XIII) unless exempted pursuant to 4VAC60-60-1150 A 3 (a), complied with the requirements of 4VAC50-60-1150, complies with the requirements of 4VAC50-60-1180 through 4VAC50-60-1190, and:

1. Prior to commencing construction, the operator shall obtain approval of an erosion and sediment control plan from the VESCP authority in the locality in which the construction activity is to occur or from another appropriate plan-approving authority authorized under the Virginia Erosion and Sediment Control Regulations, 4VAC50-30, unless the operator receives from the locality VESCP authority an "agreement in lieu of a plan" as defined in 4VAC50-30-10, or is exempt from the requirement to submit an erosion and sediment control plan by the Erosion and Sediment Control Law (§ 10.1-560 et seq. of the Code of Virginia) and Erosion and Sediment Control Regulations (4VAC50-30);

2. The stormwater discharge authorized by this state permit may be combined with other sources of stormwater that are not required to be covered under a VSMP state permit, so long as the combined discharge is in compliance with this state permit. Any discharge authorized by a different VSMP state or a VPDES permit may be commingled with discharges authorized by this state permit so long as all such discharges comply with all applicable state permits;

3. Discharges to waters for which a "total maximum daily load" (TMDL) wasteload allocation has been established are not eligible for coverage under this general permit unless they are otherwise authorized in accordance with 4VAC50-60-1170 Section II D 6 and consistent with the requirements and assumptions of the wasteload allocations in the TMDL; and

4. Discharges to waters that have been identified as impaired in the 2008 § 305(b)/303(d) Water Quality Assessment Integrated Report are not eligible for coverage under this general permit unless they are otherwise authorized in accordance with 4VAC50-60-1170 Section I H.

B. In addition to other prohibitions, the following discharges are not eligible for coverage under this general permit:

1. Discharges for which the operator has been required to obtain an individual permit according to 4VAC50-60-410 B;

2. Discharges to state waters specifically named in other State Water Control Board regulations or policies that prohibit such discharges; and

3. Stormwater discharges that the permit-issuing authority department in consultation with the State Water Control Board determines cause, may reasonably be expected to cause, or contribute to a violation of water quality standards (9VAC25-260).

C. This state permit may also be used to authorize stormwater discharges from support activities (e.g., concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated material disposal areas, borrow areas) located on-site or off-site provided that:

1. The support activity is directly related to a construction site that is required to have VSMP state permit coverage for discharges of stormwater associated with construction activity;

2. The support activity is not a commercial operation serving multiple unrelated construction projects by different operators, and does not operate beyond the completion of the construction activity at the last construction project it supports; and

3. Appropriate control measures that will be implemented to minimize pollutant discharges from the support activity are identified in a stormwater pollution prevention plan covering the discharges from the support activity areas.

D. Support activities located off-site are not required to be covered under this general permit. Discharges of stormwater from off-site support activities may be authorized under another VSMP state or a VPDES permit. Where stormwater discharges from off-site support activities are not authorized under this general permit, the land area of the off-site support activity need not be included in determining the total land disturbance acreage of the construction activity seeking general permit coverage.

E. Receipt of this general permit does not relieve any operator of the responsibility to comply with any other applicable federal, state or local statute, ordinance or regulation.

F. The permit-issuing authority department may allow exceptions to technical criteria contained in the state permit in accordance with Part III of this chapter.

4VAC50-60-1140

4VAC50-60-1140. Qualifying state and local Virginia erosion and sediment control programs.

Qualifying state or local erosion and sediment control program VESCP requirements may be incorporated by reference into the Stormwater Pollution Prevention Plan (SWPPP) required by 4VAC50-60-1170 of this state permit. Where a qualifying state or local program VESCP does not include one or more of the elements in this section, then the operator must include those elements as part of the SWPPP required by 4VAC50-60-1170 of this permit. A qualifying state or local erosion and sediment control program VESCP is one that is approved by the board, meets the requirements of 4VAC50-60-460 L and includes:

1. Requirements for construction site operators to implement appropriate erosion and sediment control measures;

2. Requirements for construction site operators to control waste such as discarded building materials, concrete truck washout, chemicals, litter, and sanitary waste at the construction site that may cause adverse impacts to water quality; and

3. Requirements for construction site operators to develop and implement a SWPPP in accordance with 4VAC50-60-1170 Section II.

GENERAL PERMIT FOR DISCHARGES OF STORMWATER FROM CONSTRUCTION ACTIVITIES

AUTHORIZATION TO DISCHARGE UNDER THE VIRGINIA STORMWATER MANAGEMENT PROGRAM AND THE VIRGINIA STORMWATER MANAGEMENT ACT

In compliance with the provisions of the Clean Water Act, as amended, and pursuant to the Virginia Stormwater Management Act and attendant regulations, operators of construction activities covered by this state permit with stormwater discharges are authorized to discharge to state waters, including discharges to a regulated MS4 system, within the boundaries of the Commonwealth of Virginia, except those specifically named in State Water Control Board and Virginia Soil and Water Conservation Board regulations that prohibit such discharges.

The authorized discharge shall be in accordance with this cover page, Section I—Discharge Authorization and Special Conditions, Section II—Stormwater Pollution Prevention Plan, and Section III—Conditions Applicable To All VSMP State Permits as set forth herein.

SECTION I
DISCHARGE AUTHORIZATION AND SPECIAL CONDITIONS

A. Coverage under this state permit.

1. During the period beginning with the date of coverage under this general permit and lasting until the state permit's expiration date, the operator is authorized to discharge stormwater from construction activities.

2. This state permit may also authorize stormwater discharges from support activities (e.g., concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated material disposal areas, borrow areas) located on-site or off-site provided that:

a. The support activity is directly related to the construction site that is required to have VSMP state permit coverage for discharges of stormwater associated with construction activity;

b. The support activity is not a commercial operation serving multiple unrelated construction projects by different operators, and does not operate beyond the completion of the construction activity at the last construction project it supports; and

c. Appropriate control measures are identified in a stormwater pollution prevention plan and implemented to address the discharges from the support activity areas.

3. There shall be no discharge of floating solids or visible foam that contravenes established standards or interferes directly or indirectly with designated uses of surface waters.

B. Limitation on coverage.

1. Post-construction discharges. This state permit does not authorize stormwater discharges that originate from the site after construction activities have been completed and the site, including any temporary support activity site, has undergone final stabilization. Post-construction industrial stormwater discharges may need to be covered by a separate VPDES permit.

2. Discharges mixed with nonstormwater. This state permit does not authorize discharges that are mixed with sources of nonstormwater, other than those discharges that are identified in Section I D 2 (Exceptions to prohibition of nonstormwater discharges) and are in compliance with Section II D 5 (Nonstormwater discharge management).

3. Discharges covered by another state permit. This state permit does not authorize stormwater discharges associated with construction activity that have been covered under an individual permit or required to obtain coverage under an alternative general permit.

4. TMDL limitation. Discharges to waters for which a wasteload allocation (WLA) for a pollutant has been established in a "total maximum daily load" (TMDL) approved by the State Water Control Board that would apply to stormwater discharges from a construction activity are not eligible for coverage under this state permit unless the stormwater pollution prevention plan (SWPPP) developed by the operator is consistent with the requirements related to TMDLs contained in Section II D 6.

5. Impaired waters limitation. Discharges to waters that have been identified as impaired in the 2008 § 305(b)/303(d) Water Quality Assessment Integrated Report are not eligible for coverage under this state permit unless the operator implements strategies and control measures consistent with Sections I H and II D 7.

C. Commingled discharges. Any discharge authorized by a different VSMP state or VPDES permit may be commingled with discharges authorized by this state permit.

D. Prohibition of nonstormwater discharges.

1. Except as provided in Sections I A 2, I C and I D 2, all discharges covered by this state permit shall be composed entirely of stormwater associated with construction activity.

2. The following nonstormwater discharges from active construction sites are authorized by this state permit provided the nonstormwater component of the discharge is in compliance with Section II D 5 (Nonstormwater discharges):

a. Discharges from fire fighting activities;

b. Fire hydrant flushings;

c. Waters used to wash vehicles where detergents are not used;

d. Water used to control dust;

e. Potable water sources, including uncontaminated waterline flushings;

f. Routine external building wash down which does not use detergents;

g. Pavement washwaters where spills or leaks of toxic or hazardous materials have not occurred (unless all spilled material has been removed) and where detergents are not used;

h. Uncontaminated air conditioning or compressor condensate;

i. Uncontaminated ground water or spring water;

j. Foundation or footing drains where flows are not contaminated with process materials such as solvents;

k. Uncontaminated excavation dewatering, and

l. Landscape irrigation.

E. Releases of hazardous substances or oil in excess of reportable quantities. The discharge of hazardous substances or oil in the stormwater discharges from the construction site shall be prevented or minimized in accordance with the stormwater pollution prevention plan for the site. This state permit does not relieve the state permittee of the reporting requirements of 40 CFR Part 110 (2002), 40 CFR Part 117 (2002) and 40 CFR Part 302 (2002) 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), 40 CFR Part 117 (2002), 40 CFR Part 302 (2002), or § 62.1-44.34.19 of the Code of Virginia occurs during a 24-hour period:

1. The SWPPP shall be signed in accordance with Section III K.

2. The SWPPP shall be retained, along with a copy of this state permit, registration statement, and acknowledgement letter from the permit-issuing authority department, at the construction site or other location easily accessible during normal business hours from the date of commencement of construction activity to the date of final stabilization. Operators with day-to-day operational control over SWPPP implementation shall have a copy of the SWPPP available at a central location on-site for the use of all operators and those identified as having responsibilities under the SWPPP whenever they are on the construction site. The SWPPP must be made available, in its entirety, to the department, the permit-issuing VSMP authority, and the operator of a municipal separate storm sewer system receiving discharges from the site for review at the time of an on-site inspection. If an on-site location is unavailable to store the SWPPP when no personnel are present, notice of the SWPPP's location must be posted near the main entrance at the construction site.

3. The operator shall make SWPPPs and all updates available upon request to the department; the permit-issuing VSMP authority; EPA; a state or local agency approving erosion and sediment control plans, grading plans, or stormwater management plans; local government officials; or the operator of a municipal separate storm sewer system receiving discharges from the site.

4. A sign or other notice must be posted conspicuously near the main entrance of the construction site. The sign or other notice must contain the following information:

a. A copy of the state permit coverage letter than includes the registration number for the construction activity; and

b. The Internet address at which a copy of the SWPPP may be found or the location of a hard copy of the SWPPP and name and telephone number of a contact person for scheduling viewing times.

For linear projects, the sign or other notice must be posted at a publicly accessible location near an active part of the construction project (e.g., where a pipeline project crosses a public road).

5. For discharges that commence on or after July 1, 2009, that have not previously held coverage under a VSMP state or VPDES permit, the operator shall make the SWPPP available to the public for review. A copy of the SWPPP for each site shall be made available on the Internet or in hard copy. The website address or contact person for access to the SWPPP shall be posted on the sign required by subdivision B 4 of this section. If not provided electronically, access to the SWPPP may be arranged upon request at a time and at a publicly accessible location convenient to the operator or his designee but shall be no less than once per month and shall be during normal business hours. If a reproduced copy of the SWPPP is provided to the requestor, the requestor shall be responsible for the costs of reproduction. Information excluded from disclosure under applicable law shall not be required to be released. Information not required to be contained within the SWPPP by this state permit is not required to be released.

C. Maintaining an updated SWPPP.

1. The operator shall amend the SWPPP whenever there is a change in design, construction, operation, or maintenance that has a significant effect on the discharge of pollutants to state waters and that has not been previously addressed in the SWPPP.

2. The SWPPP must be amended if during inspections or investigations by the operator's qualified personnel, or by local VESCP authority, VSMP authority, state or federal officials, it is determined that the existing control measures are ineffective in minimizing pollutants in stormwater discharges from the construction site. Revisions to the SWPPP shall include additional or modified control measures designed to correct problems identified. If approval by a plan-approving VSMP authority is necessary for the control measure, revisions to the SWPPP shall be completed within seven calendar days of approval. Implementation of these additional or modified control measures must be accomplished as described in Section II D 3 b.

3. Revisions to the SWPPP must be dated and signed in accordance with Section III K 2, but are not required to be certified in accordance with Section III K 4.

(2) The SWPPP shall describe control measures used to comply with applicable state or local waste disposal, sanitary sewer or septic system regulations.

(3) The SWPPP shall include a description of construction and waste materials expected to be stored on-site with updates as appropriate. The SWPPP shall also include a description of controls including storage practices, to minimize exposure of the materials to stormwater, and for spill prevention and response.

(4) The SWPPP shall include a description of pollutant sources from off-site areas (including stormwater discharges from dedicated asphalt plants and dedicated concrete plants), and a description of control measures that will be implemented at those sites to minimize pollutant discharges.

e. Applicable state or local programs. The control measures implemented at the site shall be consistent with all applicable federal, state, or local VESCP or VSMP authority requirements for erosion and sediment control and stormwater management. The SWPPP shall be updated as necessary to reflect any revisions to applicable federal, state or local VESCP or VSMP authority requirements that affect the control measures implemented at the site.

3. Maintenance of controls.

a. All control measures must be properly maintained in effective operating condition in accordance with good engineering practices and, where applicable, manufacturer specifications. If site inspections required by Section II D 4 identify control measures that are not operating effectively, maintenance shall be performed as soon as practicable to maintain the continued effectiveness of stormwater controls.

b. If site inspections required by Section II D 4 identify existing control measures that need to be modified or if additional control measures are necessary for any reason, implementation shall be completed before the next anticipated storm event. If implementation before the next anticipated storm event is impracticable, the situation shall be documented in the SWPPP and alternative control measures shall be implemented as soon as practicable.

4. Inspections. The name and phone number of qualified personnel conducting inspections shall be included in the SWPPP.

a. Inspections shall be conducted (i) at least every seven calendar days or (ii) at least once every 14 calendar days and within 48 hours following any runoff producing storm event. Where areas have been temporarily stabilized or runoff is unlikely due to winter conditions (e.g., the site is covered with snow or ice, or frozen ground exists) such inspections shall be conducted at least once every month.

b. Inspections must include all areas of the site disturbed by construction activity, off-site areas covered by the state permit, and areas used for storage of materials that are exposed to precipitation, but does not need to include areas identified pursuant to Section II A 5. Inspectors must look for evidence of, or the potential for, pollutants entering a stormwater conveyance system. Control measures identified in the SWPPP shall be inspected for proper installation, maintenance, and operation. Discharge locations, where accessible, shall be inspected to ascertain whether control measures are effective in minimizing impacts to receiving waters. 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.

c. Utility line installation, pipeline construction, and other examples of long, narrow, linear construction activities may limit the access of inspection personnel to the areas described in Section II D 4 b. Inspection of these areas could require that vehicles compromise temporarily or even permanently stabilized areas, cause additional disturbance of soils, and increase the potential for erosion. In these circumstances, controls must be inspected on the same frequencies as other construction projects, but representative inspections may be performed. For representative inspections, personnel must inspect controls along the construction site for 0.25 miles above and below each access point where a roadway, undisturbed right-of-way, or other similar feature intersects the construction site and allows access to the areas described above. The conditions of the controls along each inspected 0.25-mile segment may be considered as representative of the condition of controls along that reach extending from the end of the 0.25-mile segment to either the end of the next 0.25-mile segment, or to the end of the project, whichever occurs first. Inspection locations must be listed in the report required by Section II D 4 d.

d. A report summarizing the scope of the inspection, names and qualifications of personnel making the inspection, the dates of the inspection, major observations relating to the implementation of the SWPPP, and actions taken in accordance with Section II D 4 d of the state permit shall be made and retained as part of the SWPPP in accordance with Section III B of this state permit. Major observations should include:

(1) The location(s) of discharges of sediment or other pollutants from the site;

(2) Location(s) of control measures that need to be maintained;

(3) Location(s) of control measures that failed to operate as designed or proved inadequate for a particular location;

(4) Location(s) where additional control measures are needed that did not exist at the time of inspection;

(5) Corrective action required including any changes to the SWPPP that are necessary and implementation dates;

(6) An estimate of the amount of rainfall at the construction site (in inches) from the runoff producing storm event requiring the inspection, or if inspecting on a seven-day schedule, the amount of rainfall (in inches) since the previous inspection; and

(7) Weather information and a description of any discharges occurring at the time of inspection.

A record of each inspection and of any actions taken in accordance with Section II must be retained by the operator as part of the SWPPP for at least three years from the date that state permit coverage expires or is terminated. The inspection reports shall identify any incidents of noncompliance. Where a report does not identify any incidents of noncompliance, the report shall contain a certification that the facility is in compliance with the SWPPP and this state permit. The report shall be signed in accordance with Section III K of this state permit.

5. Nonstormwater discharge management. The SWPPP shall identify all allowable sources of nonstormwater discharges listed in Section I D 2 of this state permit that are combined with stormwater discharges from the construction activity at the site, except for flows from fire fighting activities. The SWPPP shall identify and require the implementation of appropriate control measures for the nonstormwater components of the discharge.

6. Total maximum daily loads. A total maximum daily load (TMDL) approved by the State Water Control Board may include a wasteload allocation to the regulated construction activity that identifies the pollutant for which stormwater control measures are necessary for the surface waters to meet water quality standards. The pollutant identified in a wasteload allocation as of the effective date of this state permit must be specified in the SWPPP. The SWPPP shall include strategies and control measures to ensure consistency with the assumptions and requirements of the TMDL WLA that apply to the operator's discharge. In a situation where a TMDL has specified a general wasteload allocation applicable to construction stormwater discharges, but no specific requirements for construction sites have been identified in the TMDL, the operator shall consult with the state or federal TMDL authority to confirm that meeting state permit requirements will be consistent with the approved TMDL. If the TMDL specifically precludes such discharges, the operator is not eligible for coverage under the general permit.

7. Impaired waters. In accordance with Section I H, control measures shall be protective of water quality standards for impaired waters identified as having impairments for pollutants that may be discharged from the construction activity in the 2008 § 305(b)/303(d) Water Quality Assessment Integrated Report.

For purposes of this part, a principal executive officer of a public agency includes: (i) the chief executive officer of the agency or (ii) a senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency.

2. Reports, etc. All reports required by state permits, including SWPPPs, and other information requested by the board, or the department, or the permit-issuing authority shall be signed by a person described in Section III K 1 or by a duly authorized representative of that person. A person is a duly authorized representative only if:

a. The authorization is made in writing by a person described in Section 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 operator. (A duly authorized representative may thus be either a named individual or any individual occupying a named position); and

c. The signed and dated written authorization is included in the SWPPP. A copy must be provided to the permit-issuing department and VSMP authority, if requested.

3. Changes to authorization. If an authorization under Section III K 2 is no longer accurate because a different individual or position has responsibility for the overall operation of the construction activity, a new authorization satisfying the requirements of Section III K 2 shall be submitted to the permit-issuing VSMP authority as the administering entity for the board prior to or together with any reports or information to be signed by an authorized representative.

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

"I certify under penalty of law that I have read and understand this document and that this document and all attachments were prepared in accordance with a system designed to assure that qualified personnel properly gathered and evaluated 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 operator shall comply with all conditions of this state permit. Any state permit noncompliance constitutes a violation of the Virginia Stormwater Management Act and the Clean Water Act, except that noncompliance with certain provisions of this state permit may constitute a violation of the Virginia Stormwater Management Act but not the Clean Water Act. Permit noncompliance is grounds for enforcement action; for state permit termination, revocation and reissuance, or modification; or denial of a state permit renewal application.

The operator shall comply with effluent standards or prohibitions established under § 307(a) of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish these standards or prohibitions or standards for sewage sludge use or disposal, even if this state permit has not yet been modified to incorporate the requirement.

M. Duty to reapply. If the operator wishes to continue an activity regulated by this permit after the expiration date of this state permit, the operator shall submit a new registration statement at least 90 days before the expiration date of the existing state permit, unless permission for a later date has been granted by the board. The board shall not grant permission for registration statements to be submitted later than the expiration date of the existing state permit.

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

O. State law. Nothing in this state permit shall be construed to preclude the institution of any legal action under, or relieve the operator 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 state permit conditions on "bypassing" (Section III U) and "upset" (Section III V), nothing in this state permit shall be construed to relieve the operator from civil and criminal penalties for noncompliance.

P. Oil and hazardous substance liability. Nothing in this state permit shall be construed to preclude the institution of any legal action or relieve the operator from any responsibilities, liabilities, or penalties to which the operator is or may be subject under §§ 62.1-44.34:14 through 62.1-44.34:23 of the State Water Control Law or § 311 of the Clean Water Act.

Q. Proper operation and maintenance. The operator shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances), which are installed or used by the operator to achieve compliance with the conditions of this state permit. Proper operation and maintenance also includes effective plant performance, adequate funding, adequate staffing, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems, which are installed by the operator only when the operation is necessary to achieve compliance with the conditions of this state 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 and in compliance with all applicable state and federal laws and regulations.

S. Duty to mitigate. The operator shall take all reasonable steps to minimize or prevent any discharge in violation of this state 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 an operator 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 state permit.

U. Bypass.

1. "Bypass,", as defined in 4VAC50-60-10, means the intentional diversion of waste streams from any portion of a treatment facility. The operator 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 ensure efficient operation. These bypasses are not subject to the provisions of Section III U 2 and 3 herein.

2. Notice.

a. Anticipated bypass. If the operator knows in advance of the need for a bypass, the operator shall submit prior notice to the department, if possible at least 10 days before the date of the bypass.

b. Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as required in Section III I herein.

3. Prohibition of bypass.

a. Except as provided in Section III U 1, bypass is prohibited, and the permit-issuing authority board or department may take enforcement action against an operator for bypass unless:

(1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage. Severe property damage means substantial physical damage to property, damage to the treatment facilities that causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production;

(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 operator submitted notices as required under Section III U 2.

b. The permit-issuing authority department may approve an anticipated bypass, after considering its adverse effects, if the permit-issuing authority department determines that it will meet the three conditions listed in Section III U 3 a.

V. Upset.

1. An upset, as defined in 4VAC50-60-10, means an exceptional incident in which there is unintentional and temporary noncompliance with technology-based state permit effluent limitations because of factors beyond the reasonable control of the operator. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.

2. An upset constitutes an affirmative defense to an action brought for noncompliance with technology-based state permit effluent limitations if the requirements of Section III V 2 herein 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.

3. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation.

4. An operator 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 operator can identify the cause(s) of the upset;

b. The permitted facility was at the time being properly operated;

c. The operator submitted notice of the upset as required in Section III I herein; and

d. The operator complied with any remedial measures required under Section III S herein.

5. In any enforcement proceeding, the operator seeking to establish the occurrence of an upset has the burden of proof.

W. Inspection and entry. The operator shall allow the department as the board's designee, the permit-issuing VSMP authority, EPA, or an authorized representative of either entity (including an authorized contractor), upon presentation of credentials and other documents as may be required by law to:

1. Enter upon the operator's premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of this state permit;

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

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

4. Sample or monitor at reasonable times, for the purposes of ensuring state permit compliance or as otherwise authorized by the Clean Water Act or the Virginia Stormwater Management Act, any substances or parameters at any location.

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

X. Permit State permit actions. Permits State permits may be modified, revoked and reissued, or terminated for cause. The filing of a request by the operator for a state permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any state permit condition.

Y. Transfer of state permits.

1. Permits State permits are not transferable to any person except after notice to the permit-issuing authority department. Except as provided in Section III Y 2, a state permit may be transferred by the operator to a new operator only if the state permit has been modified or revoked and reissued, or a minor modification made, to identify the new operator and incorporate such other requirements as may be necessary under the Virginia Stormwater Management Act and the Clean Water Act.

2. As an alternative to transfers under Section III Y 1, this state permit may be automatically transferred to a new operator if:

a. The current operator notifies the permit-issuing authority 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 operators containing a specific date for transfer of state permit responsibility, coverage, and liability between them; and

c. The permit-issuing authority department does not notify the existing operator and the proposed new operator of its intent to modify or revoke and reissue the state permit. If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in Section III Y 2 b.

3. For ongoing construction activity involving a change of operator, the new operator shall accept and maintain the existing SWPPP, or prepare and implement a new SWPPP prior to taking over operations at the site.

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

Part XV
General Virginia Stormwater Management Program (VSMP) Permit for Discharges of Stormwater from Small Municipal Separate Storm Sewer Systems

4VAC50-60-1200. Definitions.

The words and terms used in this part shall have the meanings defined in the Act and this chapter unless the context clearly indicates otherwise, except that for the purposes of this part:

"Date brought on line" means the date when the operator determines that a new stormwater management facility is properly functioning to meet its designed pollutant load reduction.

"MS4 Program Plan" means the completed registration statement and all approved additions, changes and modifications detailing the comprehensive program implemented by the operator under this state permit to reduce the pollutants in the stormwater discharged from its municipal separate storm sewer system (MS4) that has been submitted and accepted by the department.

"Physically interconnected" means that a MS4 directly discharges to a second MS4.

4VAC50-60-1210

4VAC50-60-1210. Purpose; delegation of authority; effective date of the state permit.

A. This VSMP general permit regulation governs stormwater discharges from regulated small municipal separate storm sewer systems (regulated small MS4s) to surface waters of the Commonwealth of Virginia.

1. Unless the small MS4 qualifies for a waiver under subdivision 3 of this subsection, operators are regulated if they operate a small MS4, including but not limited to systems operated by federal, state, tribal, and local governments, including the Virginia Department of Transportation; and:

a. The small MS4 is located in an urbanized area as determined by the latest Decennial Census by the Bureau of the Census. If the small MS4 is not located entirely within an urbanized area, only the portion that is within the urbanized area is regulated; or

b. The small MS4 is designated by the board, including where the designation is pursuant to 40 CFR Part 123.35 (b)(3) or (b)(4) (2001), or is based upon a petition under 4VAC50-60-380 D.

2. A small MS4 may be the subject of a petition pursuant to 4VAC50-60-380 D to the board to require a VSMP state permit for their discharge of stormwater. If the board determines that a small MS4 needs a state permit and the operator applies for coverage under this general permit, the operator is required to comply with the requirements of Part XV (4VAC50-60-1180 et seq.) of this chapter.

3. The board may waive the requirements otherwise applicable to a regulated small MS4 if it meets the criteria of subdivision 4 or 5 of this subsection. If a waiver is received under this subsection, the operator may subsequently be required to seek coverage under a VSMP state permit in accordance with 4VAC50-60-400 C if circumstances change. (See also 40 CFR Part 123.35 (b) (2001))

4. The board may waive state permit coverage if the regulated small MS4 serves a population of less than 1,000 within the urbanized area and meets the following criteria:

a. The system is not contributing substantially to the pollutant loadings of a physically interconnected MS4 that is regulated by the VSMP state stormwater program; and

b. Pollutants are discharged that have been identified as a cause of impairment of any water body to which the regulated small MS4 discharges but stormwater controls are not needed based on wasteload allocations that are part of a State Water Control Board established and EPA approved "total maximum daily load" (TMDL) that addresses the pollutants of concern.

5. The board may waive state permit coverage if the regulated small MS4 serves a population under 10,000 and meets the following criteria:

a. The State Water Control Board has evaluated all surface waters, including small streams, tributaries, lakes, and ponds, that receive a discharge from the regulated small MS4;

b. For all such waters, the board has determined that stormwater controls are not needed based on wasteload allocations that are part of a State Water Control Board established and EPA approved TMDL that addresses the pollutants of concern or, if a TMDL has not been developed and approved, an equivalent analysis that determines sources and allocations for the pollutants of concern;

c. For the purpose of this subdivision, the pollutants of concern include biochemical oxygen demand (BOD), sediment or a parameter that addresses sediment (such as total suspended solids, turbidity or siltation), pathogens, oil and grease, and any pollutant that has been identified as a cause of impairment of any water body that will receive a discharge from the regulated small MS4; and

d. The board has determined that future discharges from the regulated small MS4 do not have the potential to result in exceedances of water quality standards, including impairment of designated uses, or other significant water quality impacts, including habitat and biological impacts.

B. This general permit will become effective on July 9, 2008, and will expire five years from the effective date.

4VAC50-60-1220

4VAC50-60-1220. Authorization to discharge.

A. Any operator governed by this general permit is hereby authorized to discharge stormwater from the regulated small MS4 to surface waters of the Commonwealth of Virginia provided that the operator files and receives acceptance of the registration statement of 4VAC50-60-1230 by the department and files the permit fees required by Part XIII (4VAC50-60-700 et seq.) of this chapter, and provided that the operator shall not have been required to obtain an individual permit according to 4VAC50-60-410 B.

B. The operator shall not be authorized by this general permit to discharge to state waters specifically named in other State Water Control Board or board regulations or policies that prohibit such discharges.

C. Nonstormwater discharges or flows into the regulated small MS4 are authorized by this state permit and do not need to be addressed in the MS4 Program required under 4VAC50-60-1240, Section II B 3, if:

1. The nonstormwater discharges or flows are covered by a separate individual or general VPDES or VSMP state permit for nonstormwater discharges;

2. The individual nonstormwater discharges or flows have been identified in writing by the Department of Environmental Quality as de minimis discharges that are not significant sources of pollutants to state waters and do not require a VPDES permit;

3. Nonstormwater discharges or flows in the following categories have not been identified by the operator, State Water Control Board, or by the board as significant contributors of pollutants to the regulated small MS4: water line flushing, landscape irrigation, diverted stream flows, rising ground waters, uncontaminated ground water infiltration, uncontaminated pumped ground water, discharges from potable water sources, foundation drains, air conditioning condensation, irrigation water, springs, water from crawl space pumps, footing drains, lawn watering, individual residential car washing, flows from riparian habitats and wetlands, dechlorinated swimming pool discharges, street wash water, and discharges or flows from fire fighting activities; or

4. The discharge of materials resulting from a spill is necessary to prevent loss of life, personal injury, or severe property damage. The operator shall take, or ensure that the responsible party takes, all reasonable steps to minimize or prevent any adverse effect on human health or the environment. This state permit does not transfer liability for a spill itself from the party(ies) responsible for the spill to the operator nor relieve the party(ies) responsible for a spill from the reporting requirements of 40 CFR Part 117 and 40 CFR Part 302 (2001).

In the event the operator is unable to meet certain conditions of this permit due to circumstances beyond the operator's control, a written explanation of the circumstances that prevented state permit compliance shall be submitted to the department in the annual report. Circumstances beyond the control of the operator may include abnormal climatic conditions; weather conditions that make certain requirements unsafe or impracticable; or unavoidable equipment failures caused by weather conditions or other conditions beyond the reasonable control of the operator (operator error is not a condition beyond the control of the operator). The failure to provide adequate program funding, staffing or equipment maintenance shall not be an acceptable explanation for failure to meet state permit conditions. The board will determine, at its sole discretion, whether the reported information will result in an enforcement action.

D. Discharges that are excluded from obtaining a VSMP state permit pursuant to 4VAC50-60-300 are exempted from the regulatory requirements of this state permit.

E. Pursuant to 40 CFR Part 122.34 (c) (2001), for those portions of a regulated small MS4 that are covered under a VPDES permit for industrial stormwater discharges, the operator shall follow the conditions established under the VPDES permit. Upon termination of VPDES permit coverage, discharges from previously VPDES authorized outfalls shall meet the conditions of this state permit provided it has been determined by the board that an individual MS4 permit is not required.

F. Stormwater discharges from specific MS4 outfalls that have been granted conditional exclusion for "no exposure" of industrial activities and materials to stormwater under the VPDES permitting program shall obtain coverage under this VSMP general permit. The Department of Environmental Quality is responsible for determining compliance with the conditional exclusion under the State Water Control Law and attendant regulations.

G. Receipt of this VSMP general permit does not relieve any operator of the responsibility to comply with any other applicable federal, state or local statute, ordinance or regulation.

4VAC50-60-1230

4VAC50-60-1230. Permit State permit application (registration statement).

A. Deadline for submitting a registration statement.

1. Operators of regulated small MS4s designated under 4VAC50-60-1210 A 1 b, that are applying for coverage under this VSMP general permit must submit a complete registration statement to the department within 180 days of notice of designation, unless the board grants a later date.

2. In order to continue uninterrupted coverage under the VSMP general permit, operators of regulated small MS4s shall submit a new registration statement at least 90 days before the expiration date of the existing state permit, unless permission for a later date has been granted by the board.

GENERAL PERMIT FOR DISCHARGES OF STORMWATER FROM SMALL MUNICIPAL SEPARATE STORM SEWER SYSTEMS

AUTHORIZATION TO DISCHARGE UNDER THE VIRGINIA STORMWATER MANAGEMENT PROGRAM AND THE VIRGINIA STORMWATER MANAGEMENT ACT

In compliance with the provisions of the Clean Water Act, as amended and pursuant to the Virginia Stormwater Management Act and regulations adopted pursuant thereto, this state permit authorizes operators of small municipal separate storm sewer systems to discharge to surface waters within the boundaries of the Commonwealth of Virginia, except those waters specifically named in State Water Control Board and Virginia Soil and Water Conservation Board regulations or policies which prohibit such discharges.

The authorized discharge shall be in accordance with this cover page, Section I—Discharge Authorization and Special Conditions, Section II—MS4 Program and Section III—Conditions Applicable To All VSMP State Permits, as set forth herein. The operator shall utilize all legal authority provided by the laws and regulations of the Commonwealth of Virginia to control discharges to and from the MS4. This legal authority may be a combination of statute, ordinance, permit, contract, order or interjurisdictional agreements.

SECTION I
DISCHARGE AUTHORIZATION AND SPECIAL CONDITIONS

A. Coverage under this state permit. During the period beginning with the date of coverage under this general permit and lasting until the expiration and reissuance of this state permit, the operator is authorized to discharge in accordance with this state permit from the small municipal separate storm sewer system identified in the registration statement into surface waters.

B. Special conditions. A total maximum daily load (TMDL) approved by the State Water Control Board may include a wasteload allocation to the regulated small MS4 that identifies the pollutant for which stormwater controls are necessary for the surface waters to meet water quality standards. The pollutant identified in a wasteload allocation as of the effective date of this permit must be addressed through the measurable goals of the MS4 Program Plan. A wasteload allocation does not establish that the operator of a regulated small MS4 is in or out of compliance with the conditions of this permit.

1. The operator shall update its MS4 Program Plan to include measurable goals, schedules, and strategies to ensure MS4 Program consistency with the assumptions of the TMDL WLA within 18 months of permit coverage; or, within 18 months of the effective date of any reopening of this permit to include wasteloads allocated to the regulated small MS4 after issuance of permit coverage.

2. The measurable goals, schedules, strategies, and other best management practices (BMPs), required in an updated MS4 Program Plan to assure MS4 Program consistency with an approved TMDL for the pollutant identified in a WLA are, at a minimum:

a. The operator shall develop a list of its current ordinances and legal authorities, BMPs, policies, plans, procedures and contracts implemented as part of the MS4 Program that are applicable to reducing the pollutant identified in a WLA.

b. The operator shall evaluate existing ordinances and legal authorities, BMPs, policies, plans, procedures and contracts of the existing MS4 Program to determine the effectiveness of the MS4 Program in addressing reductions of the pollutant identified in the WLA. The evaluation shall identify any weakness or limitation in the MS4 Program to reduce the pollutant identified in the WLA in a manner consistent with the TMDL.

c. The operator shall develop a schedule to implement procedures and strategies that address the MS4 Program weaknesses such as timetables to update existing ordinances and legal authorities within two years, BMPs, policies, plans, procedures and contracts to ensure consistency with the assumptions of the TMDL WLA. When possible, source elimination shall be prioritized over load reduction.

d. The operator shall implement the schedule established in Section I B 2 c.

3. The operator shall integrate an awareness campaign into its existing public education and outreach program that promotes methods to eliminate and reduce discharges of the pollutant identified in the WLA. This may include additional employee training regarding the sources and methods to eliminate and minimize the discharge of the pollutant identified in the WLA.

4. The operator is encouraged to participate as a stakeholder in the development of any implementation plans developed to address the TMDL and shall incorporate applicable best management practices identified in the TMDL implementation plan in their MS4 Program Plan. The operator may choose to implement BMPs of equivalent design and efficiency instead of those identified in the TMDL implementation plan, provided that the rationale for any substituted BMP is provided and the substituted BMP is consistent with the TMDL and the WLA.

5. The operator shall develop and implement outfall reconnaissance procedures to identify potential sources of the pollutant identified in the WLA from anthropogenic activities. The operator shall conduct reconnaissance in accordance with the following:

a. Should the operator have 250 or more total outfalls discharging to the surface water identified in the WLA, the operator shall perform reconnaissance on a minimum of 250 outfalls for each WLA assigned at least once during the five-year permit period and shall perform reconnaissance on a minimum of 35 outfalls per year.

b. Should the operator have less than 250 total outfalls discharging to an identified surface water, the operator shall perform reconnaissance on all outfalls during the five-year permit period and shall annually conduct reconnaissance on a minimum of 15% of its known MS4 outfalls discharging to the surface water for which the WLA has been assigned.

The department recommends that the operator review the publication entitled "Illicit Discharge Detection and Elimination: A Guidance Manual for Program Development and Technical Assessments," EPA cooperative agreement number X-82907801-0, for guidance in implementing its outfall reconnaissance procedures. The operator shall implement procedures designed to reduce the discharge of the pollutant in a manner consistent with the TMDL. Physically interconnected MS4s may coordinate outfall reconnaissance to meet the requirements of this subdivision.

6. The operator shall evaluate all properties owned or operated by the MS4 operator that are not covered under a separate VPDES permit for potential sources of the pollutant identified in the WLA. Within three years of the required date for updating the MS4 Program Plan, the operator shall conduct a site review and characterize the runoff for those properties where it determines that the pollutant identified in the WLA is currently stored, or has been transferred, transported or historically disposed of in a manner that would expose it to precipitation in accordance with the following schedule:

a. As a part of the site review, the operator shall collect a total of two samples from a representative outfall for each identified municipal property. One sample shall be taken during each of the following six-month periods: October through March, and April through September.

b. All collected samples shall be grab samples and collected within the first 30 minutes of a runoff producing event that is greater than 0.1 inches in magnitude and that occurs at least 72 hours from the previous measurable (greater than 0.1 inch rainfall) storm event. The required 72-hour storm event interval is waived where the preceding measurable storm event did not result in a measurable discharge from the property. The required 72-hour storm event interval may also be waived where the operator documents that less than a 72-hour interval is representative for local storm events during the season when sampling is being conducted. Analytical methods shall be conducted according to procedures approved under 40 CFR Part 136 or alternative methods approved by the Environmental Protection Agency (EPA). Where an approved 40 CFR Part 136 method does not exist, the operator must use a method consistent with the TMDL.

c. For properties where there is found to be a discharge of the pollutant identified in the WLA, the operator shall develop and implement a schedule to minimize the discharge of the pollutant identified in the WLA in a manner consistent with the approved TMDL.

7. The operator shall conduct an annual characterization that estimates the volume of stormwater discharged, in cubic feet, and the quantity of pollutant identified in the WLA, in a unit consistent with the WLA, discharged by the regulated small MS4.

8. As part of the annual evaluation, the operator shall update the MS4 Program Plan to include any new information regarding the TMDL in order to ensure consistency with the TMDL.

SECTION II
MUNICIPAL SEPARATE STORM SEWER SYSTEM MANAGEMENT PROGRAM

A. The operator of a regulated small MS4 must develop, implement, and enforce a MS4 Program designed to reduce the discharge of pollutants from the regulated small MS4 to the maximum extent practicable (MEP), to protect water quality, to ensure compliance by the operator with water quality standards, and to satisfy the appropriate water quality requirements of the Clean Water Act and regulations. The MS4 Program must include the minimum control measures described in paragraph B of this section. Implementation of best management practices consistent with the provisions of an iterative MS4 Program required pursuant to this section constitutes compliance with the standard of reducing pollutants to the "maximum extent practicable", protects water quality in the absence of a TMDL wasteload allocation, ensures compliance by the operator with water quality standards, and satisfies the appropriate water quality requirements of the Clean Water Act and regulations in the absence of a TMDL WLA. The requirements of this section and those special conditions set out in Section I B also apply where a WLA is applicable.

No later than January 9, 2009, the operator shall review its existing MS4 Program Plan and submit a schedule to develop and implement programs to meet the conditions established by this permit. For operators of regulated small MS4s that are applying for initial coverage under this general permit, the schedule to develop and implement the MS4 Program Plan shall be submitted with the completed registration statement.

B. Minimum control measures.

1. Public education and outreach on stormwater impacts. Implement a public education program to distribute educational materials to the community or conduct equivalent outreach activities about the impacts of stormwater discharges on water bodies and the steps that the public can take to reduce pollutants in stormwater runoff. The department recommends that the operator review the Environmental Protection Agency (EPA) publication entitled "Getting in Step: A Guide for Conducting Watershed Outreach Campaigns," publication number EPA 841-B-03-002, for guidance in developing a public education program.

The operator shall identify, schedule, implement, evaluate and modify, as necessary, BMPs to meet the following public education and outreach measurable goals:

a. Increased individual and household knowledge about the steps that they can take to reduce stormwater pollution, placing priority on reducing impacts to impaired waters and other local water pollution concerns;

Except as provided in state permit conditions on "bypassing" (Section III U), and "upset" (Section III V) nothing in this state permit shall be construed to relieve the operator from civil and criminal penalties for noncompliance.

P. Oil and hazardous substance liability. Nothing in this state permit shall be construed to preclude the institution of any legal action or relieve the operator from any responsibilities, liabilities, or penalties to which the operator is or may be subject under §§ 62.1-44.34:14 through 62.1-44.34:23 of the State Water Control Law or § 311 of the Clean Water Act.

Q. Proper operation and maintenance. The operator shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances), which are installed or used by the operator to achieve compliance with the conditions of this state permit. Proper operation and maintenance also includes effective plant performance, adequate funding, adequate staffing, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems, which are installed by the operator only when the operation is necessary to achieve compliance with the conditions of this state 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 surface waters.

S. Duty to mitigate. The operator shall take all reasonable steps to minimize or prevent any discharge in violation of this state 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 an operator 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 state permit.

U. Bypass.

1. "Bypass," as defined in 4VAC50-60-10, means the intentional diversion of waste streams from any portion of a treatment facility. The operator 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 Sections III U 2 and U 3.

2. Notice.

a. Anticipated bypass. If the operator 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 operator shall submit notice of an unanticipated bypass as required in Section III I.

3. Prohibition of bypass.

a. Bypass is prohibited, and the board or its designee may take enforcement action against an operator 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 operator submitted notices as required under Section III U 2.

b. The board or its designee may approve an anticipated bypass, after considering its adverse effects, if the board or its designee determines that it will meet the three conditions listed above in Section III U 3 a.

V. Upset.

1. An upset, as defined in 4VAC50-60-10, constitutes an affirmative defense to an action brought for noncompliance with technology based state permit effluent limitations if the requirements of Section 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. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. 

3. An operator 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 operator can identify the cause(s) of the upset;

b. The permitted facility was at the time being properly operated;

c. The operator submitted notice of the upset as required in Section III I; and

d. The operator complied with any remedial measures required under Section III S.

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

W. Inspection and entry. The operator shall allow the department as the board's designee, or an authorized representative (including an authorized contractor acting as a representative of the administrator), upon presentation of credentials and other documents as may be required by law, to:

1. Enter upon the operator's premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of this state permit;

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

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

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

For purposes of this subsection, 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 State permit actions. Permits State permits may be modified, revoked and reissued, or terminated for cause. The filing of a request by the operator for a state permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any state permit condition.

Y. Transfer of state permits.

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

2. As an alternative to transfers under Section III Y 1, this state permit may be automatically transferred to a new operator if:

a. The current operator notifies the department at least two 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 operators containing a specific date for transfer of state permit responsibility, coverage, and liability between them; and

c. The board does not notify the existing operator and the proposed new operator of its intent to modify or revoke and reissue the state permit. If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in Section III Y 2 b.

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