Preamble: On May 24, 2011, the board amended and readopted the third set of final regulations for this regulatory action. The previous final version was published in the Virginia Register of Regulations on January 4, 2010 (26:9 VA.R. 1230-1269) and suspended by the Virginia Soil and Water Conservation Board on January 14, 2010, in response to 25 petitions received during the final adoption period. The amendments described in the summary below reflect changes made between the previous final version published on January 4, 2010, and the final version readopted on May 24, 2011.
NOTE: Chapters 137 and 370 of the 2010 Virginia Acts of Assembly stipulated that these regulations are required to become effective within 280 days after the establishment by the federal Environmental Protection Agency (EPA) of a Chesapeake Baywide Total Maximum Daily Load (TMDL), but in any event no later than December 1, 2011. As the TMDL was adopted by EPA on December 29, 2010, these regulations must be effective on or before October 5, 2011.
Summary:
Overall, this final regulatory action amends the technical criteria applicable to stormwater discharges from construction activities including postdevelopment requirements, establishes minimum criteria for locality-administered stormwater management programs (local stormwater management programs) and Department of Conservation and Recreation (department) administered stormwater management programs, specifies the authorization procedures and review procedures for local stormwater management programs, and amends the definitions section applicable to all of the Virginia Stormwater Management Program (VSMP) regulations.
Part II was modified as follows:
1. General sections applicable to all of Part II were amended or added related to authority, implementation date, general objectives, applicability of other laws and regulations, time limits on applicability of approved design criteria, grandfathering, and Chesapeake Bay Preservation Act land-disturbing activity;
2. A new Part II A was added that includes administrative criteria for regulated land-disturbing activities;
3. Water quality and quantity technical criteria were moved from Part II A to Part II B; and
4. Water quality technical standards referenced in both the time limits on applicability of approved design criteria and grandfathering sections were moved from Part II B to Part II C.
General sections in Part II were amended as follows:
1. A new section titled "Time limits on applicability of approved design criteria" was created, and language carved out the grandfathering section that specifies that any project that receives general permit coverage shall be held to the technical criteria under which permit coverage is issued and shall remain subject to those criteria for an additional two permit cycles. This represents a tightening of today's administrative processes and equates to the period within which over 90% of construction projects are typically completed.
2. The grandfathering section was updated to move away from paralleling local vesting standards and contains specified grandfathering provisions associated with projects for which local plan approval has been received; local, state, or federal funding has been obligated; or governmental bonding or public debt financing has been issued prior to July 1, 2012. For projects grandfathered under the receipt of local plan approval or the obligation of local, state, or federal funding provisions, construction needs to be completed by June 30, 2019.
3. A Chesapeake Bay Preservation Act section has been added that specifies the requirements for small land-disturbing projects within the Chesapeake Bay Act jurisdictions. These small projects, between 2,500 square feet and less than one acre, would now be subject only to state requirements, rather than state and federal requirements as federal requirements only need to extend down to one acre. These projects would not be required to receive coverage under the VSMP general permit, but would be required to receive local permits and meet the specified criteria in Parts II A and B.
New Part II A contains:
1. Requirements to inform the operator as to what is expected in order to receive general permit coverage including items such as stormwater plan or SWPPP requirements (these elements were previously outlined in Part III);
2. A TMDL requirement that an operator identify and implement additional control measures on a site for specified pollutants so that discharges are consistent with the assumptions and requirements of any applicable wasteload allocation; and
3. EPA-adopted federal effluent limitation guidelines.
In Part II B the revised water quality and quantity technical requirements applicable to stormwater discharges from construction activities include:
1. A scientifically based 0.41 lbs/acre/year phosphorus standard for new development activities statewide (prior adopted standard was 0.45). References to different standards being allowable in a UDA in order to encourage compact development were removed as it was not believed that a 0.41 standard would encourage sprawl, especially with the offsite compliance methodologies that will be available;
2. A redevelopment requirement for projects where land disturbance results in no net increase in impervious cover over the predevelopment condition with total phosphorus load reduction requirements of either 10% or 20% below the predevelopment phosphorus condition depending on the size of the land-disturbing activity. For land-disturbing activities that result in new increases in impervious cover, the new development standard shall be applied to the increased impervious area (the prior version of the regulations was not based on changes in imperviousness and did not specify the use of the new development standard for portions of a site where levels of imperviousness are being increased);
3. Water quantity minimum standards and procedures to address channel protection and flood protection including the addition of a provision stating that compliance with these minimum standards shall be deemed to satisfy the requirements of minimum standard 19 of the Virginia Erosion and Sediment Control Regulations. Under channel protection, references to stable and unstable conveyance systems were removed and under channel protection, in the energy balance formula (for natural stormwater conveyance systems), the peak flow rate and volume of runoff for the existing land use at a given storm was changed from an assumed "good pasture" condition to now utilize the peak flow rate and volume of runoff from the actual predeveloped land use condition. To moderate this calculation, there is an improvement factor inputted into the equation (0.8 for sites > 1 acre or 0.9 for sites < 1 acre); and
4. Offsite options to achieve compliance with the water quality and, where allowed, water quantity requirements. Such options incorporate those requirements specified in Chapter 523 of the 2011 Virginia Acts of Assembly. The amended language sets out conditions under which an operator must be allowed to utilize offsite compliance options and specifies that offsite options must achieve the necessary nutrient reductions prior to commencement of the operator's land disturbing activity. Additionally, the state buy down option was eliminated.
Part III was reorganized in this version of the regulations. Part III A was restructured to include both locality-administered programs and department-administered programs within the same subpart and, accordingly, Part III C was moved to Part III B and Part III D was moved to Part III C.
1. Part III A establishes the minimum criteria for a stormwater management program implemented by a stormwater program administrative authority (either a local stormwater management program or a department-administered program). Ordinance requirements for a Virginia Soil and Water Conservation Board authorized local stormwater management program have also been established. Minimum criteria for the stormwater programs include, but are not limited to, administration, plan review, inspection, enforcement, reporting, and recordkeeping.
2. Part III B establishes the procedures that the board will utilize in authorizing a locality to administer a local stormwater management program.
3. Part III C establishes the criteria the department will utilize in reviewing a locality's administration of a local stormwater management program. The primary technical change to Part III is in how local programs operate. Under the previous version of the regulations, an approved local stormwater management program was going to issue coverage under the general permit and enforce under the Stormwater Management Act and regulations. Under this final version, approved local programs operate and enforce under the auspices of a local ordinance that includes the elements of the stormwater regulations. Localities will still make sure that the applicant has received state general permit coverage prior to issuing a local land-disturbing permit. Localities must adopt ordinances that are at least as stringent as the VMSP General Permit for Discharges of Stormwater from Construction Activities. The department will enforce the VSMP General Permit for the Discharge of Stormwater from Construction Activities.
Finally, this action makes changes to definitions in Part I, which is applicable to the full body of the VSMP regulations. Unnecessary definitions are deleted, needed definitions are added, and many existing definitions are updated. In this final action, several definitions were added and other minor refinements made to address comments received. A number of definitions previously subject to deletion were moved to Part II C where they will only be applicable to those grandfathering sections.
Summary of Public Comments and Agency's Response: A summary of comments made by the public and the agency's response may be obtained from the promulgating agency or viewed at the office of the Registrar of Regulations.

In making this determination the board may consider the following factors:
a. Physical interconnections between the municipal separate storm sewers;
b. The location of discharges from the designated municipal separate storm sewer relative to discharges from municipal separate storm sewers described in subdivision 1 of this definition;
c. The quantity and nature of pollutants discharged to surface waters;
d. The nature of the receiving surface waters; and
e. Other relevant factors.
4. The board may, upon petition, designate as a large municipal separate storm sewer system, municipal separate storm sewers located within the boundaries of a region defined by a stormwater management regional authority based on a jurisdictional, watershed, or other appropriate basis that includes one or more of the systems described in this definition.
[ "Layout" means a conceptual drawing sufficient to provide for the specified stormwater management facilities required at the time of approval. ]

MEP is achieved, in part, by selecting and implementing effective structural and nonstructural best management practices (BMPs) and rejecting ineffective BMPs and replacing them with effective best management practices (BMPs). MEP is an iterative standard, which evolves over time as urban runoff management knowledge increases. As such, the operator's MS4 program must continually be assessed and modified to incorporate improved programs, control measures, BMPs, etc., to attain compliance with water quality standards.
"Medium municipal separate storm sewer system" means all municipal separate storm sewers that are either:
1. Located in an incorporated place with a population of 100,000 or more but less than 250,000 as determined by the 1990 decennial census by the Bureau of Census (40 CFR Part 122 Appendix G (2000));

a. Physical interconnections between the municipal separate storm sewers;
b. The location of discharges from the designated municipal separate storm sewer relative to discharges from municipal separate storm sewers described in subdivision 1 of this definition;
c. The quantity and nature of pollutants discharged to surface waters;
d. The nature of the receiving surface waters; or

"Watershed" means a defined land area drained by a river or stream, karst system, or system of connecting rivers or streams such that all surface water within the area flows through a single outlet. In karst areas, the karst feature to which the water drains may be considered the single outlet for the watershed.
"Wetlands" means those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.
"Whole effluent toxicity" means the aggregate toxic effect of an effluent measured directly by a toxicity test.

4VAC50-60-40. Applicability Authority and applicability.
This part specifies technical criteria for every stormwater management program and land-disturbing activity.
Pursuant to the Virginia Stormwater Management Act (§ 10.1-603.2 et seq. of the Code of Virginia), the board is required to take actions ensuring the general health, safety, and welfare of the citizens of the Commonwealth as well as protecting the quality and quantity of state waters from the potential harm of unmanaged stormwater. In addition to other authority granted to the board under the Stormwater Management Act, the board is authorized pursuant to §§ 10.1-603.2:1 and 10.1-603.4 to adopt regulations that specify [ minimum technical criteria standards and procedures ] for [ local ] stormwater management programs [ in and the ] Virginia [ Stormwater Management Program ], to establish statewide standards for stormwater management [ from for ] land-disturbing activities, and to protect properties, the quality and quantity of state waters, the physical integrity of stream channels, and other natural resources.
In accordance with the board's authority, this part establishes the minimum technical criteria and stormwater management standards that shall be employed by a state agency in accordance with an implementation schedule set by the board, or by a qualifying local program or department-administered local stormwater management program that has been approved by the board, to protect the quality and quantity of state waters from the potential harm of unmanaged stormwater runoff resulting from land-disturbing activities.
For those localities required to adopt a local stormwater management program pursuant to § 10.1-603.3 of the Code of Virginia, until a local program is approved by the board, the technical criteria required shall be that found at 4VAC50-60-1180 through 4VAC50-60-1190.
4VAC50-60-45. [ Applicability Implementation date ].
[ In accordance with the board's authority, this part establishes the minimum technical criteria and stormwater management standards that shall be employed by a state agency in accordance with an implementation schedule set by the board, or by a qualifying local program or department-administered local stormwater management program that has been approved by the board, to protect the quality and quantity of state waters from the potential harm of unmanaged stormwater runoff resulting from land-disturbing activities, except as provided in 4VAC50-60-48. The technical criteria in Part II A and Part II B shall be implemented by a stormwater program administrative authority when a VSMP General Permit for Discharges of Stormwater from Construction Activities has been issued that incorporates such criteria. Until that time, the required technical criteria shall be found in Part II C.
4VAC50-60-46. General objectives.
The physical, chemical, biological, and hydrologic characteristics and the water quality and quantity of the receiving state waters shall be maintained, protected, or improved in accordance with the requirements of this part. Objectives include, but are not limited to, supporting state designated uses and water quality standards. All control measures used shall be employed in a manner that minimizes impacts on receiving state waters.
4VAC50-60-47. Applicability of other laws and regulations.
Nothing in this chapter shall be construed as limiting the applicability of other laws and regulations, including, but not limited to, the CWA, Virginia Stormwater Management Act, Virginia Erosion and Sediment Control Law, and the Chesapeake Bay Preservation Act, except as provided in § 10.1-603.3 I of the Code of Virginia, and all applicable regulations adopted in accordance with those laws, or the rights of other federal agencies, state agencies, or local governments to impose more stringent technical criteria or other requirements as allowed by law.
4VAC50-60-47.1. Time limits on applicability of approved design criteria.
Beginning with the VSMP General Permit for Discharges of Stormwater from Construction Activities issued July 1, 2009, all land-disturbing activities that receive general permit coverage shall be conducted in accordance with the Part II B or Part II C technical criteria in place at the time of initial permit coverage and shall remain subject to those criteria for an additional two permit cycles, except as provided for in subsection D of 4VAC50-60-48. After the two additional permit cycles have passed, or should permit coverage not be maintained, portions of the project not under construction shall become subject to any new technical criteria adopted since original permit coverage was issued. For land-disturbing projects issued coverage under the July 1, 2009 permit and for which coverage was maintained, such projects shall remain subject to the technical criteria of Part II C for an additional two permits. ]
4VAC50-60-48. Grandfathering.
A. [ Land-disturbing activities that receive coverage under the VSMP General Permit for Discharges of Stormwater from Construction Activities prior to the adoption of a local stormwater management program within their jurisdiction shall not be subject to the technical criteria of Part II A, but shall be subject to the technical criteria of Part II B, until the expiration of that permit on June 30, 2014. Until June 30, 2019, any land-disturbing activity for which a currently valid proffered or conditional zoning plan, preliminary or final subdivision plat, preliminary or final site plan or zoning with a plan of development, or any document determined by the locality as being equivalent thereto, was approved by a locality prior to July 1, 2012, and for which no coverage under the VSMP General Permit for Discharges of Stormwater from Construction Activities has been issued prior to July 1, 2014, shall be considered grandfathered by the stormwater program administrative authority and shall not be subject to the technical criteria of Part II B, but shall be subject to the technical criteria of Part II C for those areas that were included in the approval, provided that the stormwater program administrative authority finds that such proffered or conditional zoning plan, preliminary or final subdivision plat, preliminary or final site plan or zoning with a plan of development, or any document determined by the locality as being equivalent thereto, (i) provides for a layout and (ii) the resulting land-disturbing activity will be compliant with the requirements of Part II C. In the event that the locality-approved document is subsequently modified or amended in a manner such that there is no increase over the previously approved plat or plan in the amount of phosphorus leaving each point of discharge of the land-disturbing activity through stormwater runoff, and such that there is no increase over the previously approved plat or plan in the volume or rate of runoff, the grandfathering shall continue as before. ]

If permit coverage continuously remains in effect for the land-disturbing activity within the entire project area, then the project shall remain subject to the Part II B Technical Criteria until June 30, 2019. Should permit coverage not be maintained or if the land-disturbing activity continues beyond June 30, 2019, portions of the project not completed shall be subject to the Part II A Technical Criteria. In the event that the qualifying significant affirmative governmental act or the VSMP permit is subsequently modified or amended in a manner such that there is no increase in the amount of phosphorus leaving the site through stormwater runoff, and such that there is no increase in the volume or rate of runoff, the grandfathering shall continue as before.
For purposes of this subsection and without limitation, the following are deemed to be significant affirmative governmental acts allowing development of a specific project: (i) the governing body has accepted proffers or proffered conditions that specify use related to a zoning amendment; (ii) the governing body has approved an application for a rezoning for a specific use or density; (iii) the governing body or board of zoning appeals has granted a special exception or use permit with conditions; (iv) the board of zoning appeals has approved a variance; (v) the governing body or its designated agent has approved a preliminary subdivision plat, site plan, or plan of development for the landowner's property and the applicant diligently pursues approval of the final plat or plan within a reasonable period of time under the circumstances; or (vi) the governing body or its designated agent has approved a final subdivision plat, site plan or plan of development for the landowner's property. For the purposes of this subsection and without limitation, for state and federal projects, the approval of state or federal funding for a project or the approval of a stormwater management plan are deemed to be significant affirmative governmental acts. B. Until June 30, 2019, for locality, state, and federal projects for which there has been an obligation of locality, state, or federal funding, in whole or in part, prior to July 1, 2012, or for which the department has approved a stormwater management plan prior to July 1, 2012, such projects shall be considered grandfathered by the stormwater program administrative authority and shall not be subject to the technical criteria of Part II B, but shall be subject to the technical criteria of Part II C for those areas that were included in the approval. ]
C. [ Where a land-disturbing activity is part of a common plan of development or sale that has obtained VSMP general permit coverage from the department prior to July 1, 2010 , the land-disturbing activity will be subject to the technical criteria of Part II B. The registration statement shall include the permit coverage number for the common plan of development or sale for which association is being claimed. For land-disturbing activities grandfathered under subsections A and B of this section, construction must be completed by June 30, 2019, or portions of the project not under construction shall become subject to the technical criteria of Part II B. ]
D. In cases where governmental bonding or public debt financing has been issued for a project prior to July 1, [ 2010 2012 ], such project shall be subject to the technical criteria of [ Part II B Part II C ].
[ E. Nothing in this section shall preclude an operator from constructing to a more stringent standard at his discretion. ]

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 which 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 post-developed stormwater runoff from the impervious cover shall be treated by an appropriate BMP as required by the post-developed condition percent impervious cover as specified in Table 1. The selected BMP shall be located, designed, and maintained to perform at the target pollutant removal efficiency specified in Table 1. Design standards and specifications for the BMPs in Table 1 that meet the required target pollutant removal efficiency will be available at the department.

C. The permit-issuing authority may determine that some watersheds or receiving stream systems require enhanced criteria in order to address the increased frequency of bankfull flow conditions (top of bank) brought on by land-disturbing activities. Therefore, in lieu of the reduction of the two-year post-developed peak rate of runoff as required in subsection B of this section, the land development project being considered shall provide 24-hour extended detention of the runoff generated by the one-year, 24-hour duration storm.
D. In addition to subsections B and C of this section permit-issuing authorities, by local ordinance may, or the board by state regulation may, adopt more stringent channel analysis criteria or design standards to ensure that the natural level of channel erosion, to the maximum extent practicable, will not increase due to the land-disturbing activities.

D. [ The local For drainage areas of 200 acres or less, the stormwater ] program [ administrative authority ] may allow for the use of the Rational Method for evaluating peak discharges [ or the Modified Rational Method for evaluating volumetric flows to stormwater conveyances with drainage areas of 200 acres or less ].
[ E. For drainage areas of 200 acres or less, the stormwater program administrative authority may allow for the use of the Modified Rational Method for evaluating volumetric flows to stormwater conveyances. ]

4VAC50-60-80. Flooding. (Repealed.)
A. Downstream properties and waterways shall be protected from damages from localized flooding due to changes in runoff rate of flow and hydrologic characteristics, including but not limited to, changes in volume, velocity, frequency, duration, and peak flow rate of stormwater runoff in accordance with the minimum design standards set out in this section.

4VAC50-60-90. Regional (watershed-wide) stormwater management plans. (Repealed.)
This section enables localities to develop regional stormwater management plans. State agencies intending to develop large tracts of land such as campuses or prison compounds are encouraged to develop regional plans where practical.
The objective of a regional stormwater management plan is to address the stormwater management concerns in a given watershed with greater economy and efficiency by installing regional stormwater management facilities versus individual, site-specific facilities. The result will be fewer stormwater management facilities to design, build and maintain in the affected watershed. It is also anticipated that regional stormwater management facilities will not only help mitigate the impacts of new development, but may also provide for the remediation of erosion, flooding or water quality problems caused by existing development within the given watershed.
If developed, a regional plan shall, at a minimum, address the following:
1. The specific stormwater management issues within the targeted watersheds.
2. The technical criteria in 4VAC50-60-40 through 4VAC50-60-80 as needed based on subdivision 1 of this section.
3. The implications of any local comprehensive plans, zoning requirements, local ordinances pursuant to the Chesapeake Bay Preservation Area Designation and Management Regulations adopted pursuant to the Chesapeake Bay Preservation Act, and other planning documents.

1. Such plans shall ensure that offsite reductions equal to or greater than those that would be required on each contributing [ land-disturbing ] site are achieved within the same HUC or within another locally designated watershed. Pertaining to water quantity objectives, the plan may provide for implementation of a combination of channel improvement, stormwater detention, or other measures that are satisfactory to the [ qualifying ] local [ stormwater management ] program to prevent downstream erosion and flooding.
2. If the land use assumptions upon which the plan was based change or if any other amendments are deemed necessary by the [ qualifying ] local [ stormwater management ] program, [ the qualifying local such ] program shall provide plan amendments to the [ board department ] for review and approval.
3. During the plan's implementation, the [ qualifying ] local [ stormwater management ] program shall [ account for document ] nutrient reductions accredited to the BMPs specified in the plan.
4. State and federal agencies may develop comprehensive stormwater management plans, and may participate in locality-developed comprehensive [ watershed ] stormwater management plans where practicable and permitted by the [ qualifying ] local [ stormwater management ] program.
4VAC50-60-93. Stormwater management plan development. (Reserved.)
A. A stormwater management plan for a land-disturbing activity shall apply these stormwater management technical criteria to the entire land-disturbing activity.
B. Individual lots or planned phases of developments shall not be considered separate land-disturbing activities, but rather the entire development shall be considered a single land-disturbing activity.
C. The stormwater management plan shall consider all sources of surface runoff and all sources of subsurface and groundwater flows converted to surface runoff.
[ 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 watershed-specific values for the average land cover condition based upon 4VAC50-60-110.
"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. ]

4VAC50-60-96. Comprehensive watershed stormwater management plans Water quality.
A. Local programs may develop comprehensive watershed stormwater management plans to be approved by the department that meet the water quality objectives, quantity objectives, or both of this chapter:
1. Such plans shall ensure that offsite reductions equal to or greater than those that would be required on each contributing land-disturbing site are achieved within the same HUC or within another locally designated watershed. Pertaining to water quantity objectives, the plan may provide for implementation of a combination of channel improvement, stormwater detention, or other measures that are satisfactory to the local program to prevent downstream erosion and flooding.

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.

("Rules"), to consider issues related to discovery in Commission proceedings. The Commission invited interested parties to address, among other things, whether: (i) the Commission's Staff ("Staff") should be subject to additional discovery and, if so, what types of additional discovery and in what types of proceedings; and (ii) whether experts or consultants retained by Staff should be subject to discovery and, if so, what types of discovery and in what types of proceedings. The Commission also invited interested parties to address how subjecting Staff to additional discovery may affect: (i) the Commission's ability to meet statutory deadlines in certain types of proceedings; (ii) available resources and efficiency in handling cases; (iii) the Staff's ability to interact informally with regulated entities and their customers to effect resolution of disputes; (iv) the ability of Staff to work with regulated entities in competitive industries; and (v) the protection of sensitive information provided to Staff by regulated entities.
The Commission received eight comments in response to its Order for Notice of Proceeding. The Virginia Committee for Fair Utility Rates and the Old Dominion Committee for Fair Utility Rates ("Committees"), representing large industrial customers, filed comments in support of maintaining the Commission's existing Rules. The following filed comments suggesting revisions to the Rules: Columbia Gas of Virginia, Inc. ("Columbia Gas"); Washington Gas Light Company ("Washington Gas"); Verizon Virginia Inc. and Verizon South Inc. ("Verizon"); and the Virginia Telecommunications Industry Association ("VTIA"). One individual filed comments adopting the position of the VTIA. The Office of the Attorney General's Division of Consumer Counsel ("Consumer Counsel") filed a Notice of Participation and raised no concerns with the existing Rules. Shenandoah Valley Electric Cooperative filed comments in support of electronic filing and management of documents.
On April 8, 2011, the Staff filed its Response to the comments submitted herein, addressing the necessity for the suggested revisions. Staff noted that no electric, water, or sewer utilities filed comments raising concerns with the Commission's Rules, nor did any companies or individuals associated with the financial services industry.
On May 26, 2011, the Commission issued an Order for Notice and Hearing to Consider Proposed Revisions to Part IV of the Commission's Rules of Practice and Procedure ("Order for Notice and Hearing"). The Order for Notice and Hearing, among other things: (1) identified proposed revisions to Part IV of the Rules ("Proposed Rules"), which expand the discovery on Staff in adjudicatory and regulatory cases; (2) directed that public notice of the Proposed Rules be given; (3) permitted interested persons and Staff to file written or electronic comments on the Proposed Rules; and (4) scheduled a public hearing to receive oral comment from interested persons on the Proposed Rules.
The public hearing was convened on July 12, 2011, at which time oral comment was received from the following, seriatim: Verizon; Virginia Electric & Power Company ("Virginia Power"); Columbia Gas; Consumer Counsel; Committees; and Staff.
NOW THE COMMISSION, upon consideration of this matter, is of the opinion and finds that we shall adopt the rules appended hereto as Attachment A, effective as of September 1, 2011. In making our determination in this matter, the Commission has considered all of the comments and arguments submitted in this proceeding. The rules approved herein, which satisfy all legal requirements, significantly expand Staff's obligation to respond to discovery in both adjudicatory and regulatory proceedings before the Commission.1
For example, in adjudicatory cases, Staff is required to provide the following – which will necessarily include any information that is favorable to the defendant:
All relevant statements made by the defendant;
All relevant statements made by Staff's witnesses;
All relevant statements made by witnesses that Staff does not intend to call to testify at the hearing;
All documents and objects that Staff intends to introduce at the hearing;
All documents and objects that Staff obtained for purposes of the case (regardless of whether such will be introduced at the hearing); and
A list of witnesses that Staff intends to call to testify at the hearing.2
In addition, the rules adopted herein likewise require Staff to respond to discovery in regulatory proceedings and to provide the following:
• All factual information supporting workpapers of Staff or an expert or consultant filing testimony on behalf of Staff;
• All electronic spreadsheets, including underlying formulas and assumptions, supporting workpapers of Staff or an expert or consultant filing testimony on behalf of Staff;
• All documents relied upon as a basis for recommendations or assertions in prefiled Staff testimony, Staff reports or exhibits filed by Staff, or by an expert or consultant filing testimony on behalf of Staff; and
• The identity of other formal proceedings in which an expert or consultant filing testimony on behalf of Staff testified regarding the same or a substantially similar subject matter.3
The Commission received no opposition to the Proposed Rules from any investor-owned electric utility, any electric cooperative, any natural gas utility, any water and/or sewer company, any insurance company or agent, the banking industry, the securities industry, or any consumers or representatives thereof.
Virginia Power supported the Proposed Rules, stating that the rules "are adequate and will serve the parties well."4 Similarly, Allegheny Power submitted a letter in support of the Proposed Rules.5 Columbia Gas stated that the Proposed Rules "adequately address the comments" filed by Columbia Gas in this case.6 Washington Gas also "does not object to the Proposed Rules, and does not, at this time, propose any revisions to the Proposed Rules."7
The Committees – comprised of large industrial users of electricity – argued that, even though they often take positions "fiercely adverse to those of … Staff:" (a) no party has shown that a discovery problem actually exists; (b) no additional discovery of Staff should be permitted; (c) the Proposed Rules are not necessary; and (d) additional obligations on Staff would be contrary to the public interest.8 The Committees, however, did not ultimately object to adoption of the Proposed Rules.9
Consumer Counsel supported the Proposed Rules, explaining that the rules "expand the scope of discovery, both in regulatory and adjudicatory proceedings."10
Verizon and VTIA objected to the Proposed Rules.11 While these participants asserted that the Proposed Rules should be further modified, we note that the final rules adopted herein extensively and meaningfully increase the discovery on Staff. The new discovery rules, for example, require Staff to provide: (1) evidence favorable to the defendant; (2) hearing exhibits and other documents obtained for the case; (3) a list of witnesses; (4) statements obtained from witnesses and non-witnesses; (5) factual information, including electronic spreadsheets, supporting Staff's workpapers; (6) access to information from experts testifying on behalf of Staff; and (7) documents relied upon by Staff or its testifying consultant. Indeed, Verizon conceded that, even for criminal cases, (i) Commonwealth Attorneys' prosecutorial staff is not subject to the type of discovery that Verizon seeks herein, and (ii) the federal Jencks Act (regarding discovery in federal criminal cases)12 does not go as far as the discovery rules adopted here in terms of the discovery requirements placed on federal prosecutorial staff.13
Accordingly, IT IS ORDERED THAT:
(1) The Commission's Rules of Practice and Procedure, as set forth in 5 VAC 5-20-10 et seq., are hereby revised and adopted as set forth on the attachment to this Order Adopting Revisions to Part IV of the Commission's Rules of Practice and Procedure, effective as of September 1, 2011.
(2) The Commission's Division of Information Resources shall forward this Order Adopting Revisions to Part IV of the Commission's Rules of Practice and Procedure and the rules adopted herein to the Registrar of Virginia for publication in the Virginia Register.
(3) This case shall be dismissed from the Commission's docket of active proceedings, and the papers filed herein shall be placed in the Commission's file for ended causes.
AN ATTESTED COPY hereof shall be sent by the Clerk of the Commission to all public utilities providing service within the Commonwealth of Virginia and to representatives of the insurance, banking, and securities industries as shown on the attached appendices and to the individuals and organizations on the service list attached hereto.
1 The rules approved herein also reflect changes to the Proposed Rules that, among other things: (i) require Staff to provide evidence that it does not intend to introduce at the hearing, including evidence favorable to the defendant; (ii) define a witness "statement" as used in these rules; and (iii) clarify that these rules do not require disclosure of information prohibited by statute or other legal privilege.

5VAC5-20-260. Interrogatories to parties or requests for production of documents and things.
The commission staff and any party in a formal proceeding before the commission, other than a proceeding under 5VAC5-20-100 A, may serve written interrogatories or requests for production of documents upon a party, to be answered by the party served, or if the party served is an entity, by an officer or agent of the entity, who shall furnish to the staff or requesting party information as is known. Interrogatories or requests for production of documents, including workpapers pursuant to 5VAC5-20-270, that cannot be timely answered before the scheduled hearing date may be served only with leave of the commission for good cause shown and upon such conditions as the commission may prescribe. Such otherwise untimely interrogatories or requests for production of documents, including workpapers pursuant to 5VAC5-20-270, may not be served until such leave is granted. No interrogatories Interrogatories or requests for production of documents may be served upon a member of the commission staff, except or an expert or consultant filing testimony on behalf of the commission staff, in a proceeding under 5VAC5-20-80 to discover: (i) factual information that supports the workpapers submitted by the staff pursuant to 5VAC5-20-270, including electronic spreadsheets that include underlying formulas and assumptions; (ii) any other documents relied upon as a basis for recommendations or assertions in prefiled testimony, staff reports or exhibits filed by staff, or by an expert or consultant filing testimony on behalf of the staff; or (iii) the identity of other formal proceedings in which an expert or consultant filing testimony on behalf of the staff testified regarding the same or a substantially similar subject matter. The disclosure of communications within the commission shall not be required and, except for good cause shown, no interrogatories or requests for production of documents may be served upon a member of the commission staff, or an expert or consultant filing testimony on behalf of the staff, prior to the filing of staff's testimony. All interrogatories and requests for production of documents shall be filed with the Clerk of the Commission. Responses to interrogatories and requests for production of documents shall not be filed with the Clerk of the Commission.
The response to each interrogatory or document request shall identify by name the person making the response. Any objection to an interrogatory or document request shall identify the interrogatory or document request to which the objection is raised, and shall state with specificity the basis and supporting legal theory for the objection. Objections shall be served with the list of responses or in such manner as the commission may designate by order. Responses and objections to interrogatories or requests for production of documents shall be served within 10 days of receipt, unless otherwise ordered by the commission. Upon motion promptly made and accompanied by a copy of the interrogatory or document request and the response or objection that is subject to the motion, the commission will rule upon the validity of the objection; the objection otherwise will be considered sustained.
Interrogatories or requests for production of documents may relate to any matter not privileged, which is relevant to the subject matter involved, including the existence, description, nature, custody, condition, and location of any books, documents, or other tangible things, and the identity and location of persons having knowledge of evidentiary value. It is not grounds for objection that the information sought will be inadmissible at the hearing if the information appears reasonably calculated to lead to the discovery of admissible evidence.
Where the response to an interrogatory or document request may only be derived or ascertained from the business records of the party questioned, from an examination, audit, or inspection of business records, or from a compilation, abstract, or summary of business records, and the burden of deriving or ascertaining the response is substantially the same for one entity as for the other, a response is sufficient if it (i) identifies by name and location all records from which the response may be derived or ascertained; and (ii) tenders to the inquiring party reasonable opportunity to examine, audit, or inspect the records subject to objection as to their proprietary or confidential nature. The inquiring party bears the expense of making copies, compilations, abstracts, or summaries.
5VAC5-20-280. Discovery applicable only to 5VAC5-20-90 proceedings.
This rule applies only to a proceeding in which a defendant is subject to a monetary penalty or injunction, or revocation, cancellation, or curtailment of a license, certificate of authority, registration, or similar authority previously issued by the commission to the defendant:
1. Discovery of material in possession of the commission staff. Upon written motion of the defendant, the commission shall permit the defendant to inspect and, at the defendant's expense, copy or photograph [ (exclusive of investigative notes) ]: (i) any relevant written or recorded statements, the existence of which is known, after reasonable inquiry, by the commission staff counsel assigned to the matter to be within the custody, possession, or control of commission staff, made by (a) the defendant, or representatives, or agents of the defendant if the defendant is other than an individual, or (b) any witness whom the commission staff intends [ , or does not intend, ] to call to testify at the hearing [ (exclusive of investigative notes) ], to a commission staff member or law enforcement officer; (ii) designated books, tangible objects, papers, documents, or copies or portions thereof, that are within the custody, possession, or control of commission staff and that commission staff intends to introduce into evidence at the hearing [ or that the commission staff obtained for the purpose of the instant proceeding ]; and (iii) the list of the witnesses that commission staff intends to call to testify at the hearing. Upon good cause shown [ to protect the identity of persons not named as a defendant ], the commission or hearing examiner may direct the commission staff to withhold disclosure of [ the identity of the persons described in clause (iii) material requested under this rule. The term "statement" as used in relation to any witness (other than a defendant) described in clause (i) of this subdivision includes a written statement made by said witness and signed or otherwise adopted or approved by him, and verbatim transcriptions or recordings of a witness' statement that are made contemporaneously with the statement by the witness ].
A motion by the defendant [ or staff ] under this rule shall be filed and served at least 10 [ 20 30 ] days before the hearing date. The motion shall include all relief sought. A subsequent motion may be made only upon a showing of cause as to why the motion would be in the interest of justice. An order or ruling granting relief under this rule shall specify the time, place, and manner of making discovery and inspection permitted, and may prescribe such terms and conditions as the commission may determine.
[ The Upon written motion of the ] commission staff [ , staff ] may also obtain the list of witnesses that the defendant intends to call to testify at the hearing, and inspect, copy, and photograph, at commission staff's expense, the evidence that the defendant intends to introduce into evidence at the hearing.
The commission staff and the defendant shall be required to produce the information described above as directed by the commission or hearing examiner, but not later than 10 days prior to the scheduled hearing; and the admission of any additional evidence not provided in accordance herewith shall not be denied solely on the basis that it was not produced timely, provided the additional evidence was produced to commission staff or the defendant as soon as practicable prior to the hearing, or prior to the introduction of such evidence at the hearing. The requirement to produce the information described in this section shall be in addition to any requirement by commission staff or the defendant to timely respond to an interrogatory or document request made pursuant to 5VAC5-20-260.
Nothing in this rule shall require the disclosure of any information, the disclosure of which is prohibited by statute [ or other legal privilege ]. The disclosure of the results of a commission staff investigation or work product of commission staff counsel shall not be required.
2. Depositions. After commencement of a proceeding to which this rule applies, the commission staff or a party may take the testimony of (i) a party, or (ii) a person not a party for good cause shown to the commission or hearing examiner, other than a member of the commission staff, by deposition on oral examination or by written questions. Depositions may be used for any purpose for which they may be used in the courts of record of the Commonwealth. Except where the commission or hearing examiner finds that an emergency exists, no deposition may be taken later than 10 days in advance of the formal hearing. The attendance of witnesses at depositions may be compelled by subpoena. Examination and cross-examination of the witness shall be as at hearing. Depositions may be taken in the City of Richmond or in the town, city, or county in which the deposed person resides, is employed, or does business. The parties and the commission staff, by agreement, may designate another place for the taking of the deposition. Reasonable notice of the intent to take a deposition must be given in writing to the commission staff counsel and to each party to the action, stating the time and place where the deposition is to be taken. A deposition may be taken before any person (the "officer") authorized to administer oaths by the laws of the jurisdiction in which the deposition is to be taken. The officer shall certify his authorization in writing, administer the oath to the deponent, record or cause to be recorded the testimony given, and note any objections raised. In lieu of participating in the oral examination, a party or the commission staff may deliver sealed written questions to the officer, who shall propound the questions to the witness. The officer may terminate the deposition if convinced that the examination is being conducted in bad faith or in an unreasonable manner. Costs of the deposition shall be borne by the party noticing the deposition, unless otherwise ordered by the commission.
3. Requests for admissions. The commission staff or a party to a proceeding may serve upon a party written requests for admission. Each matter on which an admission is requested shall be stated separately. A matter shall be deemed admitted unless within 21 days of the service of the request, or some other period the commission may designate, the party to whom the request is directed serves upon the requesting party a written answer addressing or objecting to the request. The response shall set forth in specific terms a denial of the matter set forth or an explanation as to the reasons the responding party cannot truthfully admit or deny the matter set forth. Requests for admission shall be filed with the Clerk of the Commission and simultaneously served on commission staff counsel and on all parties to the proceeding.

The board shall not grant permission for applications to be submitted later than the expiration date of the existing permit.
E. Completeness.
1. The board shall not issue a permit before receiving a complete application for a permit except for VPDES general permits. An application for a permit is complete when the board receives an application form and any supplemental information which are completed to its satisfaction. The completeness of any application for a permit shall be judged independently of the status of any other permit application or permit for the same facility or activity.
2. No application for a VPDES permit to discharge sewage into or adjacent to state waters from a privately owned treatment works serving, or designed to serve, 50 or more residences shall be considered complete unless the applicant has provided the department with notification from the State Corporation Commission that the applicant is incorporated in the Commonwealth and is in compliance with all regulations and relevant orders of the State Corporation Commission.
3. No application for a new individual VPDES permit authorizing a new discharge of sewage, industrial wastes, or other wastes shall be considered complete unless it contains notification from the county, city, or town in which the discharge is to take place that the location and operation of the discharging facility are consistent with applicable ordinances adopted pursuant to Chapter 22 (§ 15.2-2200 et seq.) of Title 15.2 of the Code of Virginia. The county, city or town shall inform in writing the applicant and the board of the discharging facility's compliance or noncompliance not more than 30 days from receipt by the chief administrative officer, or his agent, of a request from the applicant. Should the county, city or town fail to provide such written notification within 30 days, the requirement for such notification is waived. The provisions of this subsection shall not apply to any discharge for which a valid VPDES permit had been issued prior to March 10, 2000.
4. A permit application shall not be considered complete if the board has waived application requirements under subsection J or P of this section and the EPA has disapproved the waiver application. If a waiver request has been submitted to the EPA more than 210 days prior to permit expiration and the EPA has not disapproved the waiver application 181 days prior to permit expiration, the permit application lacking the information subject to the waiver application shall be considered complete.
5. In accordance with § 62.1-44.19:3 A of the Code of Virginia, no application for a permit or variance to authorize the storage of sewage sludge shall be complete unless it contains certification from the governing body of the locality in which the sewage sludge is to be stored that the storage site is consistent with all applicable ordinances. The governing body shall confirm or deny consistency within 30 days of receiving a request for certification. If the governing body does not so respond, the site shall be deemed consistent.
F. Information requirements. All applicants for VPDES permits, other than POTWs and other TWTDS, shall provide the following information to the department, using the application form provided by the department (additional information required of applicants is set forth in subsections G through K of this section).
1. The activities conducted by the applicant which require it to obtain a VPDES permit;
2. Name, mailing address, and location of the facility for which the application is submitted;
3. Up to four SIC codes which best reflect the principal products or services provided by the facility;

8. A brief description of the nature of the business.
G. Application requirements for existing manufacturing, commercial, mining, and silvicultural dischargers. Existing manufacturing, commercial mining, and silvicultural dischargers applying for VPDES permits, except for those facilities subject to the requirements of 9VAC25-31-100 H, shall provide the following information to the department, using application forms provided by the department.
1. The latitude and longitude of each outfall to the nearest 15 seconds and the name of the receiving water.
2. A line drawing of the water flow through the facility with a water balance, showing operations contributing wastewater to the effluent and treatment units. Similar processes, operations, or production areas may be indicated as a single unit, labeled to correspond to the more detailed identification under subdivision 3 of this subsection. The water balance must show approximate average flows at intake and discharge points and between units, including treatment units. If a water balance cannot be determined (for example, for certain mining activities), the applicant may provide instead a pictorial description of the nature and amount of any sources of water and any collection and treatment measures.
3. A narrative identification of each type of process, operation, or production area which contributes wastewater to the effluent for each outfall, including process wastewater, cooling water, and storm water run-off; the average flow which each process contributes; and a description of the treatment the wastewater receives, including the ultimate disposal of any solid or fluid wastes other than by discharge. Processes, operations, or production areas may be described in general terms (for example, dye-making reactor, distillation tower). For a privately owned treatment works, this information shall include the identity of each user of the treatment works. The average flow of point sources composed of storm water may be estimated. The basis for the rainfall event and the method of estimation must be indicated.
4. If any of the discharges described in subdivision 3 of this subsection are intermittent or seasonal, a description of the frequency, duration and flow rate of each discharge occurrence (except for storm water run-off, spillage or leaks).
5. If an effluent guideline promulgated under § 304 of the CWA applies to the applicant and is expressed in terms of production (or other measure of operation), a reasonable measure of the applicant's actual production reported in the units used in the applicable effluent guideline. The reported measure must reflect the actual production of the facility.
6. If the applicant is subject to any present requirements or compliance schedules for construction, upgrading or operation of waste treatment equipment, an identification of the abatement requirement, a description of the abatement project, and a listing of the required and projected final compliance dates.
7. a. Information on the discharge of pollutants specified in this subdivision (except information on storm water discharges which is to be provided as specified in 9VAC25-31-120). When quantitative data for a pollutant are required, the applicant must collect a sample of effluent and analyze it for the pollutant in accordance with analytical methods approved under 40 CFR Part 136 (2005). When no analytical method is approved the applicant may use any suitable method but must provide a description of the method. When an applicant has two or more outfalls with substantially identical effluents, the board may allow the applicant to test only one outfall and report that the quantitative data also apply to the substantially identical outfalls. The requirements in e and f of this subdivision that an applicant must provide quantitative data for certain pollutants known or believed to be present do not apply to pollutants present in a discharge solely as the result of their presence in intake water; however, an applicant must report such pollutants as present. Grab samples must be used for pH, temperature, cyanide, total phenols, residual chlorine, oil and grease, fecal coliform, and fecal streptococcus. For all other pollutants, 24-hour composite samples must be used. However, a minimum of one grab sample may be taken for effluents from holding ponds or other impoundments with a retention period greater than 24 hours. In addition, for discharges other than storm water discharges, the board may waive composite sampling for any outfall for which the applicant demonstrates that the use of an automatic sampler is infeasible and that the minimum of four grab samples will be a representative sample of the effluent being discharged.
b. For storm water discharges, all samples shall be collected from the discharge resulting from a storm event that is greater than 0.1 inch and at least 72 hours from the previously measurable (greater than 0.1 inch rainfall) storm event. Where feasible, the variance in the duration of the event and the total rainfall of the event should not exceed 50% from the average or median rainfall event in that area. For all applicants, a flow-weighted composite shall be taken for either the entire discharge or for the first three hours of the discharge. The flow-weighted composite sample for a storm water discharge may be taken with a continuous sampler or as a combination of a minimum of three sample aliquots taken in each hour of discharge for the entire discharge or for the first three hours of the discharge, with each aliquot being separated by a minimum period of 15 minutes (applicants submitting permit applications for storm water discharges under 9VAC25-31-120 C may collect flow-weighted composite samples using different protocols with respect to the time duration between the collection of sample aliquots, subject to the approval of the board). However, a minimum of one grab sample may be taken for storm water discharges from holding ponds or other impoundments with a retention period greater than 24 hours. For a flow-weighted composite sample, only one analysis of the composite of aliquots is required. For storm water discharge samples taken from discharges associated with industrial activities, quantitative data must be reported for the grab sample taken during the first 30 minutes (or as soon thereafter as practicable) of the discharge for all pollutants specified in 9VAC25-31-120 B 1. For all storm water permit applicants taking flow-weighted composites, quantitative data must be reported for all pollutants specified in 9VAC25-31-120 except pH, temperature, cyanide, total phenols, residual chlorine, oil and grease, fecal coliform, and fecal streptococcus. The board may allow or establish appropriate site-specific sampling procedures or requirements, including sampling locations, the season in which the sampling takes place, the minimum duration between the previous measurable storm event and the storm event sampled, the minimum or maximum level of precipitation required for an appropriate storm event, the form of precipitation sampled (snow melt or rain fall), protocols for collecting samples under 40 CFR Part 136 (2005), and additional time for submitting data on a case-by-case basis. An applicant is expected to know or have reason to believe that a pollutant is present in an effluent based on an evaluation of the expected use, production, or storage of the pollutant, or on any previous analyses for the pollutant. (For example, any pesticide manufactured by a facility may be expected to be present in contaminated storm water run-off from the facility.)
c. Every applicant must report quantitative data for every outfall for the following pollutants:
Biochemical oxygen demand (BOD5)
Chemical oxygen demand
Total organic carbon
Total suspended solids
Ammonia (as N)
Temperature (both winter and summer)
pH
d. The board may waive the reporting requirements for individual point sources or for a particular industry category for one or more of the pollutants listed in subdivision 7 c of this subsection if the applicant has demonstrated that such a waiver is appropriate because information adequate to support issuance of a permit can be obtained with less stringent requirements.
e. Each applicant with processes in one or more primary industry category (see 40 CFR Part 122 Appendix A (2005)) contributing to a discharge must report quantitative data for the following pollutants in each outfall containing process wastewater:
(1) The organic toxic pollutants in the fractions designated in Table I of 40 CFR Part 122 Appendix D (2005) for the applicant's industrial category or categories unless the applicant qualifies as a small business under subdivision 8 of this subsection. Table II of 40 CFR Part 122 Appendix D (2005) lists the organic toxic pollutants in each fraction. The fractions result from the sample preparation required by the analytical procedure which uses gas chromatography/mass spectrometry. A determination that an applicant falls within a particular industrial category for the purposes of selecting fractions for testing is not conclusive as to the applicant's inclusion in that category for any other purposes; and
(2) The pollutants listed in Table III of 40 CFR Part 122 Appendix D (2005) (the toxic metals, cyanide, and total phenols).
f. (1) Each applicant must indicate whether it knows or has reason to believe that any of the pollutants in Table IV of 40 CFR Part 122 Appendix D (2005) (certain conventional and nonconventional pollutants) is discharged from each outfall. If an applicable effluent limitations guideline either directly limits the pollutant or, by its express terms, indirectly limits the pollutant through limitations on an indicator, the applicant must report quantitative data. For every pollutant discharged which is not so limited in an effluent limitations guideline, the applicant must either report quantitative data or briefly describe the reasons the pollutant is expected to be discharged.
(2) Each applicant must indicate whether it knows or has reason to believe that any of the pollutants listed in Table II or Table III of 40 CFR Part 122 Appendix D (2005) (the toxic pollutants and total phenols) for which quantitative data are not otherwise required under subdivision 7 e of this subsection, is discharged from each outfall. For every pollutant expected to be discharged in concentrations of 10 ppb or greater the applicant must report quantitative data. For acrolein, acrylonitrile, 2,4 dinitrophenol, and 2-methyl-4,6 dinitrophenol, where any of these four pollutants are expected to be discharged in concentrations of 100 ppb or greater the applicant must report quantitative data. For every pollutant expected to be discharged in concentrations less than 10 ppb, or in the case of acrolein, acrylonitrile, 2,4 dinitrophenol, and 2-methyl-4,6 dinitrophenol, in concentrations less than 100 ppb, the applicant must either submit quantitative data or briefly describe the reasons the pollutant is expected to be discharged. An applicant qualifying as a small business under subdivision 8 of this subsection is not required to analyze for pollutants listed in Table II of 40 CFR Part 122 Appendix D (2005) (the organic toxic pollutants).
g. Each applicant must indicate whether it knows or has reason to believe that any of the pollutants in Table V of 40 CFR Part 122 Appendix D (2005) (certain hazardous substances and asbestos) are discharged from each outfall. For every pollutant expected to be discharged, the applicant must briefly describe the reasons the pollutant is expected to be discharged, and report any quantitative data it has for any pollutant.
h. Each applicant must report qualitative data, generated using a screening procedure not calibrated with analytical standards, for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) if it:
(1) Uses or manufactures 2,4,5-trichlorophenoxy acetic acid (2,4,5,-T); 2-(2,4,5-trichlorophenoxy) propanoic acid (Silvex, 2,4,5,-TP); 2-(2,4,5-trichlorophenoxy) ethyl, 2,2-dichloropropionate (Erbon); O,O-dimethyl O-(2,4,5-trichlorophenyl) phosphorothioate (Ronnel); 2,4,5-trichlorophenol (TCP); or hexachlorophene (HCP); or
(2) Knows or has reason to believe that TCDD is or may be present in an effluent.
8. An applicant which qualifies as a small business under one of the following criteria is exempt from the requirements in subdivision 7 e (1) or 7 f (1) of this subsection to submit quantitative data for the pollutants listed in Table II of 40 CFR Part 122 Appendix D (2005) (the organic toxic pollutants):
a. For coal mines, a probable total annual production of less than 100,000 tons per year; or
b. For all other applicants, gross total annual sales averaging less than $100,000 per year (in second quarter 1980 dollars).
9. A listing of any toxic pollutant which the applicant currently uses or manufactures as an intermediate or final product or byproduct. The board may waive or modify this requirement for any applicant if the applicant demonstrates that it would be unduly burdensome to identify each toxic pollutant and the board has adequate information to issue the permit.
10. Reserved.
11. An identification of any biological toxicity tests which the applicant knows or has reason to believe have been made within the last three years on any of the applicant's discharges or on a receiving water in relation to a discharge.
12. If a contract laboratory or consulting firm performed any of the analyses required by subdivision 7 of this subsection, the identity of each laboratory or firm and the analyses performed.
13. In addition to the information reported on the application form, applicants shall provide to the board, at its request, such other information, including pertinent plans, specifications, maps and such other relevant information as may be required, in scope and details satisfactory to the board, as the board may reasonably require to assess the discharges of the facility and to determine whether to issue a VPDES permit. The additional information may include additional quantitative data and bioassays to assess the relative toxicity of discharges to aquatic life and requirements to determine the cause of the toxicity.
H. Application requirements for manufacturing, commercial, mining and silvicultural facilities which discharge only nonprocess wastewater. Except for storm water discharges, all manufacturing, commercial, mining and silvicultural dischargers applying for VPDES permits which discharge only nonprocess wastewater not regulated by an effluent limitations guideline or new source performance standard shall provide the following information to the department using application forms provided by the department:
1. Outfall number, latitude and longitude to the nearest 15 seconds, and the name of the receiving water;
2. Date of expected commencement of discharge;
3. An identification of the general type of waste discharged, or expected to be discharged upon commencement of operations, including sanitary wastes, restaurant or cafeteria wastes, or noncontact cooling water. An identification of cooling water additives (if any) that are used or expected to be used upon commencement of operations, along with their composition if existing composition is available;
4. a. Quantitative data for the pollutants or parameters listed below, unless testing is waived by the board. The quantitative data may be data collected over the past 365 days, if they remain representative of current operations, and must include maximum daily value, average daily value, and number of measurements taken. The applicant must collect and analyze samples in accordance with 40 CFR Part 136 (2005). Grab samples must be used for pH, temperature, oil and grease, total residual chlorine, and fecal coliform. For all other pollutants, 24-hour composite samples must be used. New dischargers must include estimates for the pollutants or parameters listed below instead of actual sampling data, along with the source of each estimate. All levels must be reported or estimated as concentration and as total mass, except for flow, pH, and temperature.
(1) Biochemical oxygen demand (BOD5).
(2) Total suspended solids (TSS).
(3) Fecal coliform (if believed present or if sanitary waste is or will be discharged).
(4) Total residual chlorine (if chlorine is used).

(11) Temperature (winter and summer).
b. The board may waive the testing and reporting requirements for any of the pollutants or flow listed in subdivision 4 a of this subsection if the applicant submits a request for such a waiver before or with his application which demonstrates that information adequate to support issuance of a permit can be obtained through less stringent requirements.
c. If the applicant is a new discharger, he must submit the information required in subdivision 4 a of this subsection by providing quantitative data in accordance with that section no later than two years after commencement of discharge. However, the applicant need not submit testing results which he has already performed and reported under the discharge monitoring requirements of his VPDES permit.
d. The requirements of subdivisions 4 a and 4 c of this subsection that an applicant must provide quantitative data or estimates of certain pollutants do not apply to pollutants present in a discharge solely as a result of their presence in intake water. However, an applicant must report such pollutants as present. Net credit may be provided for the presence of pollutants in intake water if the requirements of 9VAC25-31-230 G are met;
5. A description of the frequency of flow and duration of any seasonal or intermittent discharge (except for storm water run-off, leaks, or spills);
6. A brief description of any treatment system used or to be used;
7. Any additional information the applicant wishes to be considered, such as influent data for the purpose of obtaining net credits pursuant to 9VAC25-31-230 G;
8. Signature of certifying official under 9VAC25-31-110; and
9. Pertinent plans, specifications, maps and such other relevant information as may be required, in scope and details satisfactory to the board.

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

9VAC25-31-790. Removal credits.
A. General.
1. Definitions for the purpose of this section:
"Removal" means a reduction in the amount of a pollutant in the POTW's effluent or alteration of the nature of a pollutant during treatment at the POTW. The reduction or alteration can be obtained by physical, chemical or biological means and may be the result of specifically designed POTW capabilities or may be incidental to the operation of the treatment system. Removal as used in this subpart shall not mean dilution of a pollutant in the POTW.
"Sludge requirements" means the following statutory provisions and regulations or permits issued thereunder (or more stringent Virginia or local regulations): § 405 of the CWA; the Solid Waste Disposal Act (SWDA) (42 USC § 6901 et seq.) (including Title II more commonly referred to as the Resource Conservation Recovery Act (RCRA) (42 USC § 6901 et seq.) and Virginia regulations contained in any Virginia sludge management plan prepared pursuant to Subtitle D of SWDA); the Clean Air Act (42 USC § 4701 et seq.); the Toxic Substances Control Act (15 USC § 2601 et seq.); and the Marine Protection, Research and Sanctuaries Act (33 USC § 1401 et seq.).
2. General. Any POTW receiving wastes from an industrial user to which a categorical pretreatment standards applies may, at its discretion and subject to the conditions of this section, grant removal credits to reflect removal by the POTW of pollutants specified in the categorical pretreatment standards. The POTW may grant a removal credit equal to or, at its discretion, less than its consistent removal rate. Upon being granted a removal credit, each affected industrial user shall calculate its revised discharge limits in accordance with subdivision 4 of this subsection. Removal credits may only be given for indicator or surrogate pollutants regulated in a categorical pretreatment standard if the categorical pretreatment statement so specifies.
3. Conditions for authorization to give removal credits. A POTW is authorized to give removal credits only if the following conditions are met;
a. Application. The POTW applies for, and receives, authorization from the director to give a removal credit in accordance with the requirements and procedures specified in subsection E of this section;
b. Consistent removal determination. The POTW demonstrates and continues to achieve consistent removal of the pollutant in accordance with subsection B of this section;
c. POTW local pretreatment program. The POTW has an approved pretreatment program in accordance with and to the extent required by this part; provided, however, a POTW which does not have an approved pretreatment program may, pending approval of such a program, conditionally give credits as provided in subsection D of this section;
d. Sludge requirements. The granting of removal credits will not cause the POTW to violate the local, state and federal sludge requirements which apply to the sludge management method chosen by the POTW. Alternatively, the POTW can demonstrate to the director that even though it is not presently in compliance with applicable sludge requirements, it will be in compliance when the industrial users to whom the removal credit would apply is required to meet its categorical pretreatment standards as modified by the removal credit. If granting removal credits forces a POTW to incur greater sludge management costs than would be incurred in the absence of granting removal costs, the additional sludge management costs will not be eligible for EPA grant assistance. Removal credits may be made available for the following pollutants:
(1) For any pollutant listed in Appendix G-I of the regulation incorporated by reference in 9VAC25-31-750 for the use or disposal practice employed by the POTW, when the requirements of Part VI of this chapter for that practice are met;
(2) For any pollutant listed in Appendix G-II of the regulation incorporated by reference in 9VAC25-31-750 for the use or disposal practice employed by the POTW when the concentration for a pollutant listed in Appendix G-II of the regulation incorporated by reference in 9VAC25-31-750 in the sewage sludge that is used or disposed does not exceed the concentration for the pollutant in Appendix G-II of the regulation incorporated by reference in 9VAC25-31-750; and
(3) For any pollutant in sewage sludge when the POTW disposes all of its sewage sludge in a municipal solid waste landfill that meets the criteria in the Code of Virginia and the Solid Waste Management Regulation, 9VAC20-80 Regulations, 9VAC20-81;
e. VPDES permit limitations. The granting of removal credits will not cause a violation of the POTW's permit limitations or conditions. Alternatively, the POTW can demonstrate to the director that even though it is not presently in compliance with applicable limitations and conditions in its VPDES permit, it will be in compliance when the industrial user or users to whom the removal credit would apply is required to meet its categorical pretreatment standard or standards, as modified by the removal credit provision.
4. Calculation of revised discharge limits. Revised discharge limits for a specific pollutant shall be derived by use of the following formula:
where:
x = pollutant discharge limit specified in the applicable categorical pretreatment standard
r = removal credit for that pollutant as established under subsection B of this section (percentage removal expressed as a proportion, i.e., a number between 0 and 1)
y = revised discharge limit for the specified pollutant (expressed in same units as x)
B. Establishment of removal credits; demonstration of consistent removal.
1. Definition of "consistent removal." "Consistent removal" means the average of the lowest 50% of the removal measured according to subdivision 2 of this subsection. All sample data obtained for the measured pollutant during the time period prescribed in subdivision 2 of this subsection must be reported and used in computing consistent removal. If a substance is measurable in the influent but not in the effluent, the effluent level may be assumed to be the limit of measurement, and those data may be used by the POTW at its discretion and subject to approval by the director. If the substance is not measurable in the influent, the data may not be used. Where the number of samples with concentrations equal to or above the limit of measurement is between eight and 12, the average of the lowest six removals shall be used. If there are less than eight samples with concentrations equal to or above the limit of measurement, the director may approve alternate means for demonstrating consistent removal. The term "measurement" refers to the ability of the analytical method or protocol to quantify as well as identify the presence of the substance in question.
2. Consistent removal data. Influent and effluent operational data demonstrating consistent removal or other information, as provided for in subdivision 1 of this subsection, which demonstrates consistent removal of the pollutants for which discharge limit revisions are proposed. This data shall meet the following requirements:
a. Representative data; seasonal. The data shall be representative of yearly and seasonal conditions to which the POTW is subjected for each pollutant for which a discharge limit revision is proposed;
b. Representative data; quality and quantity. The data shall be representative of the quality and quantity of normal effluent and influent flow if such data can be obtained. If such data are unobtainable, alternate data or information may be presented for approval to demonstrate consistent removal as provided for in subdivision 1 of this subsection;
c. Sampling procedures: composite.
(1) The influent and effluent operational data shall be obtained through 24-hour flow-proportional composite samples. Sampling may be done manually or automatically, and discretely or continuously. For discrete sampling, at least 12 aliquots shall be composited. Discrete sampling may be flow-proportioned either by varying the time interval between each aliquot or the volume of each aliquot. All composites must be flow proportional to each stream flow at time of collection of influent aliquot or to the total influent flow since the previous influent aliquot. Volatile pollutant aliquots must be combined in the laboratory immediately before analysis.
(2)(a) Twelve samples shall be taken at approximately equal intervals throughout one full year. Sampling must be evenly distributed over the days of the week so as to include no-workdays as well as workdays. If the director determines that this schedule will not be most representative of the actual operation of the POTW treatment plant, an alternative sampling schedule will be approved.
(b) In addition, upon the director's concurrence, a POTW may utilize an historical data base amassed prior to July 24, 1996, provide that such data otherwise meet the requirements of this paragraph. In order for the historical data base to be approved it must present a statistically valid description of daily, weekly and seasonal sewage treatment plant loadings and performance for at least one year.
(3) Effluent sample collection need not be delayed to compensate for hydraulic detention unless the POTW elects to include detention time compensation or unless the director requires detention time compensation. The director may require that each effluent sample be taken approximately one detention time later than the corresponding influent sample when failure to do so would result in an unrepresentative portrayal of actual POTW operation. The detention period is to be based on a 24-hour average daily flow value. The average daily flow used will be based upon the average of the daily flows during the same month of the previous year.
d. Sampling procedures: Grab. Where composite sampling is not an appropriate sampling technique, a grab sample or samples shall be taken to obtain influent and effluent operational data. Collection of influent grab samples should precede collection of effluent samples by approximately one detention period. The detention period is to be based on a 24-hour average daily flow value. The average daily flow used will be based upon the average of the daily flows during the same month of the previous year. Grab samples will be required, for example, where the parameters being evaluated are those, such as cyanide and phenol, which may not be held for any extended period because of biological, chemical or physical interactions which take place after sample collection and affect the results. A grab sample is an individual sample collected over a period of time not exceeding 15 minutes;
e. Analytical methods. The sampling referred to in subdivisions 2 a through d of this subsection and an analysis of these samples shall be performed in accordance with the techniques prescribed in 40 CFR Part 136 (2005) and amendments thereto. Where 40 CFR Part 136 (2005) does not contain sampling or analytical techniques for the pollutant in question, or where the administrator determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analysis shall be performed using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the POTW or other parties, approved by the administrator; and
f. Calculation of removal. All data acquired under the provisions of this section must be submitted to the department. Removal for a specific pollutant shall be determined either, for each sample, by measuring the difference between the concentrations of the pollutant in the influent and effluent of the POTW and expressing the difference as a percentage of the influent concentration, or, where such data cannot be obtained, removal may be demonstrated using other data or procedures subject to concurrence by the director as provided for in subdivision 1 of this subsection.
C. Provisional credits. For pollutants which are not being discharged currently (i.e., new or modified facilities, or production changes) the POTW may apply for authorization to give removal credits prior to the initial discharge of the pollutant. Consistent removal shall be based provisionally on data from treatability studies or demonstrated removal at other treatment facilities where the quality and quantity of influent are similar. Within 18 months after the commencement of discharge of pollutants in question, consistent removal must be demonstrated pursuant to the requirements of subsection B of this section. If, within 18 months after the commencement of the discharge of the pollutant in question, the POTW cannot demonstrate consistent removal pursuant to the requirements of subsection B of this section, the authority to grant provisional removal credits shall be terminated by the director and all industrial users to whom the revised discharge limits had been applied shall achieve compliance with the applicable categorical pretreatment standards within a reasonable time, not to exceed the period of time prescribed in the applicable categorical pretreatment standards, as may be specified by the director.
D. Exception to POTW pretreatment program requirement. A POTW required to develop a local pretreatment program by 9VAC25-31-800 may conditionally give removal credits pending approval of such a program in accordance with the following terms and conditions:
1. All industrial users who are currently subject to a categorical pretreatment standard and who wish conditionally to receive a removal credit must submit to the POTW the information required in 9VAC25-31-840 B 1 through 7 (except new or modified industrial users must only submit the information required by 9VAC25-31-840 B 1 through 6), pertaining to the categorical pretreatment standard as modified by the removal credit. The industrial users shall indicate what additional technology, if any, will be needed to comply with the categorical pretreatment standard or standards as modified by the removal credit;
2. The POTW must have submitted to the department an application for pretreatment program approval meeting the requirements of 9VAC25-31-800 and 9VAC25-31-810 in a timely manner, not to exceed the time limitation set forth in a compliance schedule for development of a pretreatment program included in the POTW's VPDES permit, but in no case later than July 1, 1983, where no permit deadline exists;
3. The POTW must:
a. Compile and submit data demonstrating its consistent removal in accordance with subsection B of this section;
b. Comply with the conditions specified in subdivision A 3 of this section; and
c. Submit a complete application for removal credit authority in accordance with subsection E of this section;
4. If a POTW receives authority to grant conditional removal credits and the director subsequently makes a final determination, after appropriate notice, that the POTW failed to comply with the conditions in subdivisions 2 and 3 of this subsection, the authority to grant conditional removal credits shall be terminated by the director and all industrial users to whom the revised discharge limits had been applied shall achieve compliance with the applicable categorical pretreatment standards within a reasonable time, not to exceed the period of time prescribed in the applicable categorical pretreatment standards, as may be specified by the director;
5. If a POTW grants conditional removal credits and the POTW or the director subsequently makes a final determination, after appropriate notice, that the industrial user or users failed to comply with the conditions in subdivision 1 of this subsection, the conditional credit shall be terminated by the POTW or the director for the noncomplying industrial user or users and the industrial user or users to whom the revised discharge limits had been applied shall achieve compliance with the applicable categorical pretreatment standards within a reasonable time, not to exceed the period of time prescribed in the applicable categorical pretreatment standards, as may be specified by the director. The conditional credit shall not be terminated where a violation of the provisions of this paragraph results from causes entirely outside of the control of the industrial user or users or the industrial user or users had demonstrated subsequential compliance; and
6. The director may elect not to review an application for conditional removal credit authority upon receipt of such application, in which case the conditionally revised discharge limits will remain in effect until reviewed by the director. This review may occur at any time in accordance with the procedures of 9VAC25-31-830, but in no event later than the time of any pretreatment program approval or any VPDES permit reissuance thereunder.
E. POTW application for authorization to give removal credits and director review.
1. Who must apply. Any POTW that wants to give a removal credit must apply for authorization from the director.
2. To whom application is made. An application for authorization to give removal credits (or modify existing ones) shall be submitted by the POTW to the department.
3. When to apply. A POTW may apply for authorization to give or modify removal credits at any time.
4. Contents of the application. An application for authorization to give removal credits must be supported by the following information:
a. List of pollutants. A list of pollutants for which removal credits are proposed;
b. Consistent removal data. The data required pursuant to subsection B of this section;
c. Calculation of revised discharge limits. Proposed revised discharge limits for each affected subcategory of industrial users calculated in accordance with subdivision A 4 of this section;
d. Local pretreatment program certification. A certification that the POTW has an approved local pretreatment program or qualifies for the exception to this requirement found at subsection D of this section;
e. Sludge management certification. A specific description of the POTW's current methods of using or disposing of its sludge and a certification that the granting of removal credits will not cause a violation of the sludge requirements identified in subdivision A 3 d of this section; and
f. VPDES permit limit certification. A certification that the granting of removal credits will not cause a violation of the POTW's VPDES permit limits and conditions as required in subdivision A 3 e of this section.
5. Director review. The director shall review the POTW's application for authorization to give or modify removal credits in accordance with the procedures of 9VAC25-31-830 and shall, in no event, have more than 180 days from public notice of an application to complete review.
6. Nothing in this part precludes an industrial user or other interested party from assisting the POTW in preparing and presenting the information necessary to apply for authorization.
F. Continuation and withdrawal of authorization.
1. Effect of authorization. Once a POTW has received authorization to grant removal credits for a particular pollutant regulated in a categorical pretreatment standard it may automatically extend that removal credit to the same pollutant when it is regulated in other categorical standards, unless granting the removal credit will cause the POTW to violate the sludge requirements identified in subdivision A 3 d of this section or its VPDES permit limits and conditions as required by subdivision A 3 e of this section. If a POTW elects at a later time to extend removal credits to a certain categorical pretreatment standard, industrial subcategory or one or more industrial users that initially were not granted removal credits, it must notify the department.
2. Inclusion in POTW permit. Once authority is granted, the removal credits shall be included in the POTW's VPDES permit as soon as possible and shall become an enforceable requirement of the POTW's VPDES permit. The removal credits will remain in effect for the term of the POTW's VPDES permit, provided the POTW maintains compliance with the conditions specified in subdivision 4 of this subsection.
3. Compliance monitoring. Following authorization to give removal credits, a POTW shall continue to monitor and report on (at such intervals as may be specified by the director, but in no case less than once per year) the POTW's removal capabilities. A minimum of one representative sample per month during the reporting period is required, and all sampling data must be included in the POTW's compliance report.
4. Modification or withdrawal of removal credits.
a. Notice of POTW. The director shall notify the POTW if, on the basis of pollutant removal capability reports received pursuant to subdivision 3 of this subsection or other relevant information available to it, the director determines:
(1) That one or more of the discharge limit revisions made by the POTW, of the POTW itself, no longer meets the requirements of this section, or
(2) That such discharge limit revisions are causing a violation of any conditions or limits contained in the POTW's VPDES Permit.
b. Corrective action. If appropriate corrective action is not taken within a reasonable time, not to exceed 60 days unless the POTW or the affected industrial users demonstrate that a longer time period is reasonably necessary to undertake the appropriate corrective action, the director shall either withdraw such discharge limits or require modifications in the revised discharge limits.
c. Public notice of withdrawal or modification. The director shall not withdraw or modify revised discharge limits unless it shall first have notified the POTW and all industrial users to whom revised discharge limits have been applied, and made public, in writing, the reasons for such withdrawal or modification, and an opportunity is provided for a public hearing. Following such notice and withdrawal or modification, all industrial users to whom revised discharge limits had been applied, shall be subject to the modified discharge limits or the discharge limits prescribed in the applicable categorical pretreatment standards, as appropriate, and shall achieve compliance with such limits within a reasonable time (not to exceed the period of time prescribed in the applicable categorical pretreatment standards) as may be specified by the director.
G. Removal credits in state-run pretreatment programs. Where the director elects to implement a local pretreatment program in lieu of requiring the POTW to develop such a program the POTW will not be required to develop a pretreatment program as a precondition to obtaining authorization to give removal credits. The POTW will, however, be required to comply with the other conditions of subdivision A 3 of this section.
H. Compensation for overflow. For the purpose of this section, "overflow" means the intentional or unintentional diversion of flow from the POTW before the POTW treatment plant. POTWs which at least once annually overflow untreated wastewater to receiving waters may claim consistent removal of a pollutant only by complying with either subdivision 1 or 2 of this subsection. However, this subsection shall not apply where industrial users can demonstrate that overflow does not occur between the industrial users and the POTW treatment plant:
1. The industrial user provides containment or otherwise ceases or reduces discharges from the regulated processes which contain the pollutant for which an allowance is requested during all circumstances in which an overflow event can reasonably be expected to occur at the POTW or at a sewer to which the industrial user is connected. Discharges must cease or be reduced, or pretreatment must be increased, to the extent necessary to compensate for the removal not being provided by the POTW. Allowances under this provision will only be granted where the POTW submits to the department evidence that:
a. All industrial users to which the POTW proposes to apply this provision have demonstrated the ability to contain or otherwise cease or reduce, during circumstances in which an overflow event can reasonably be expected to occur, discharges from the regulated processes which contain pollutants for which an allowance is requested;
b. The POTW has identified circumstances in which an overflow event can reasonably be expected to occur, and has a notification or other viable plan to insure that industrial users will learn of an impending overflow in sufficient time to contain, cease or reduce discharging to prevent untreated overflows from occurring. The POTW must also demonstrate that it will monitor and verify the data required in subdivision 1 c of this subsection, to insure that industrial users are containing, ceasing or reducing operations during POTW system overflow; and
c. All industrial users to which the POTW proposes to apply this provision have demonstrated the ability and commitment to collect and make available, upon request by the POTW, the director or EPA Regional Administrator, daily flow reports or other data sufficient to demonstrate that all discharges from regulated processes containing the pollutant for which the allowance is requested were contained, reduced or otherwise ceased, as appropriate, during all circumstances in which an overflow event was reasonably expected to occur; or
2. a. The consistent removal claimed is reduced pursuant to the following equation:
where:
rm = POTW's consistent removal rate for that pollutant as established under subsections A 1 and B 2 of this section
rc = removal corrected by the overflow factor
Z = hours per year that overflow occurred between the industrial user or users and the POTW treatment plant, the hours either to be shown in the POTW's current VPDES permit application or the hours, as demonstrated by verifiable techniques, that a particular industrial user's discharge overflows between the industrial user and the POTW treatment plant.
b. The POTW is complying with all VPDES permit requirements and any additional requirements in any order or decree, issued pursuant to the Clean Water Act affecting combined sewer outflows. These requirements include, but are not limited to, any combined sewer overflow requirements that conform to the Combined Sewer Overflow Control Policy.
9VAC25-151-190. Sector L - Landfills, land application sites and open dumps.
A. Discharges covered under this section. The requirements listed under this section apply to storm water discharges associated with industrial activity from waste disposal at landfills, land application sites, and open dumps that receive or have received industrial wastes (Industrial Activity Code "LF"), including sites subject to regulation under Subtitle D of RCRA. Open dumps are solid waste disposal units that are not in compliance with state/federal criteria established under RCRA Subtitle D. Landfills, land application sites, and open dumps that have storm water discharges from other types of industrial activities such as vehicle maintenance, truck washing, and/or recycling may be subject to additional requirements specified elsewhere in this permit.
B. Special conditions. Prohibition of nonstorm water discharges. In addition to the general nonstorm water prohibition in Part I B 1, the following discharges are not covered by this permit: leachate, gas collection condensate, drained free liquids, contaminated ground water, laboratory wastewater, and contact washwater from washing truck and railcar exteriors and surface areas that have come in direct contact with solid waste at the landfill facility.
C. Definitions.
"Contaminated storm water" means storm water that comes in direct contact with landfill wastes, the waste handling and treatment areas, or landfill wastewater as defined below. Some specific areas of a landfill that may produce contaminated storm water include, but are not limited to: the open face of an active landfill with exposed waste (no cover added); the areas around wastewater treatment operations; trucks, equipment or machinery that has been in direct contact with the waste; and waste dumping areas.
"Drained free liquids" means aqueous wastes drained from waste containers (e.g., drums, etc.) prior to landfilling.
"Landfill wastewater" as defined in 40 CFR Part 445 (2007) (Landfills Point Source Category) means all wastewater associated with, or produced by, landfilling activities except for sanitary wastewater, noncontaminated storm water, contaminated groundwater, and wastewater from recovery pumping wells. Landfill process wastewater includes, but is not limited to, leachate, gas collection condensate, drained free liquids, laboratory derived wastewater, contaminated storm water and contact washwater from washing truck, equipment, and railcar exteriors and surface areas that have come in direct contact with solid waste at the landfill facility.
"Leachate" means liquid that has passed through or emerged from solid waste and contains soluble, suspended, or miscible materials removed from such waste.
"Noncontaminated storm water" means storm water that does not come into direct contact with landfill wastes, the waste handling and treatment areas, or landfill wastewater as defined above. Noncontaminated storm water includes storm water that flows off the cap, cover, intermediate cover, daily cover, and/or final cover of the landfill.
D. Storm water pollution prevention plan requirements. In addition to the requirements in Part III, the SWPPP shall include, at a minimum, the following items.
1. Site description.
a. Site map. The site map shall identify where any of the following may be exposed to precipitation/surface runoff: active and closed landfill cells or trenches; active and closed land application areas; locations where open dumping is occurring or has occurred; locations of any known leachate springs or other areas where uncontrolled leachate may commingle with runoff; and leachate collection and handling systems.
b. Summary of potential pollutant sources. The SWPPP shall also include a description of potential pollutant sources associated with any of the following: fertilizer, herbicide and pesticide application; earth/soil moving; waste hauling and loading/unloading; outdoor storage of significant materials including daily, interim and final cover material stockpiles as well as temporary waste storage areas; exposure of active and inactive landfill and land application areas; uncontrolled leachate flows; and failure or leaks from leachate collection and treatment systems.
2. Storm water controls.
a. Preventive maintenance program. As part of the preventive maintenance program, the permittee shall maintain: all containers used for outdoor chemical/significant materials storage to prevent leaking; all elements of leachate collection and treatment systems to prevent commingling of leachate with storm water; and the integrity and effectiveness of any intermediate or final cover (including making repairs to the cover as necessary to minimize the effects of settlement, sinking, and erosion).
b. Good housekeeping measures. As part of the good housekeeping program, the permittee shall consider providing protected storage areas for pesticides, herbicides, fertilizer and other significant materials.
c. Routine facility inspections.
(1) Inspections of active sites. Operating landfills, open dumps, and land application sites shall be inspected at least once every seven days. Qualified personnel shall inspect areas of landfills that have not yet been finally stabilized, active land application areas, areas used for storage of materials/wastes that are exposed to precipitation, stabilization and structural control measures, leachate collection and treatment systems, and locations where equipment and waste trucks enter and exit the site. Erosion and sediment control measures shall be observed to ensure they are operating correctly. For stabilized sites and areas where land application has been completed, or where the climate is seasonally arid (annual rainfall averages from 0 to 10 inches) or semi-arid (annual rainfall averages from 10 to 20 inches), inspections shall be conducted at least once every month.
(2) Inspections of inactive sites. Inactive landfills, open dumps, and land application sites shall be inspected at least quarterly. Qualified personnel shall inspect landfill (or open dump) stabilization and structural erosion control measures and leachate collection and treatment systems, and all closed land application areas.
d. Recordkeeping and internal reporting procedures. Landfill and open dump owners shall provide for a tracking system for the types of wastes disposed of in each cell or trench of a landfill or open dump. Land application site owners shall track the types and quantities of wastes applied in specific areas.

f. Sediment and erosion control plan. Landfill and open dump owners shall provide for temporary stabilization of materials stockpiled for daily, intermediate, and final cover. Stabilization practices to consider include, but are not limited to, temporary seeding, mulching, and placing geotextiles on the inactive portions of the stockpiles. Landfill and open dump owners shall provide for temporary stabilization of inactive areas of the landfill or open dump which have an intermediate cover but no final cover. Landfill and open dump owners shall provide for temporary stabilization of any landfill or open dumping areas which have received a final cover until vegetation has established itself. Land application site owners shall also stabilize areas where waste application has been completed until vegetation has been established.
g. Comprehensive site compliance evaluation. Areas contributing to a storm water discharge associated with industrial activities at landfills, open dumps and land application sites shall be evaluated for evidence of, or the potential for, pollutants entering the drainage system.
E. Numeric effluent limitations. As set forth at 40 CFR Part 445 Subpart B (2007), the numeric limitations in Table 190-1 apply to contaminated storm water discharges from municipal solid waste landfills (MSWLFs) that have not been closed in accordance with 40 CFR 258.60 (2006), and contaminated storm water discharges from those landfills that are subject to the provisions of 40 CFR Part 257 (2006) (these include CDD landfills (also known as C&D landfills), and industrial landfills) except for discharges from any of the facilities described in subdivisions 1 through 4 of this subsection:
1. Landfills operated in conjunction with other industrial or commercial operations when the landfill only receives wastes generated by the industrial or commercial operation directly associated with the landfill;
2. Landfills operated in conjunction with other industrial or commercial operations when the landfill receives wastes generated by the industrial or commercial operation directly associated with the landfill and also receives other wastes provided the other wastes received for disposal are generated by a facility that is subject to the same provisions in 40 CFR Subchapter N (2007) as the industrial or commercial operation or the other wastes received are of similar nature to the wastes generated by the industrial or commercial operation;
3. Landfills operated in conjunction with centralized waste treatment (CWT) facilities subject to 40 CFR Part 437 (2007) so long as the CWT facility commingles the landfill wastewater with other nonlandfill wastewater for discharge. A landfill directly associated with a CWT facility is subject to this part if the CWT facility discharges landfill wastewater separately from other CWT wastewater or commingles the wastewater from its landfill only with wastewater from other landfills; or
4. Landfills operated in conjunction with other industrial or commercial operations when the landfill receives wastes from public service activities so long as the company owning the landfill does not receive a fee or other remuneration for the disposal service.

Part II
Permit Applications and Special VPDES Permit Programs
9VAC25-31-100. Application for a permit.
A. Duty to apply. Any person who discharges or proposes to discharge pollutants or who owns or operates a sludge-only facility whose sewage sludge use or disposal practice is regulated by 9VAC25-31-420 through 9VAC25-31-720 and who does not have an effective permit, except persons covered by general permits, excluded from the requirement for a permit by this chapter, or a user of a privately owned treatment works unless the board requires otherwise, shall submit a complete application to the department in accordance with this section. The requirements for concentrated animal feeding operations are described in subdivisions C 1 and 3 of 9VAC25-31-130.
B. Who applies. When a facility or activity is owned by one person but is operated by another person, it is the operator's duty to obtain a permit.
C. Time to apply.
1. Any person proposing a new discharge, shall submit an application at least 180 days before the date on which the discharge is to commence, unless permission for a later date has been granted by the board. Facilities proposing a new discharge of storm water associated with industrial activity shall submit an application 180 days before that facility commences industrial activity which may result in a discharge of storm water associated with that industrial activity. Different submittal dates may be required under the terms of applicable general permits. Persons proposing a new discharge are encouraged to submit their applications well in advance of the 90 or 180 day requirements to avoid delay. New discharges composed entirely of storm water, other than those dischargers identified in 9VAC25-31-120 A 1, shall apply for and obtain a permit according to the application requirements in 9VAC25-31-120 B.
2. All TWTDS whose sewage sludge use or disposal practices are regulated by 9VAC25-31-420 through 9VAC25-31-720 must submit permit applications according to the applicable schedule in subdivision 2 a or b of this subsection.
a. A TWTDS with a currently effective VPDES permit must submit a permit application at the time of its next VPDES permit renewal application. Such information must be submitted in accordance with subsection D of this section.
b. Any other TWTDS not addressed under subdivision 2 a of this subsection must submit the information listed in subdivisions 2 b (1) through (5) of this subsection to the department within one year after publication of a standard applicable to its sewage sludge use or disposal practice(s), using a form provided by the department. The board will determine when such TWTDS must submit a full permit application.
(1) The TWTDS's name, mailing address, location, and status as federal, state, private, public or other entity;
(2) The applicant's name, address, telephone number, and ownership status;
(3) A description of the sewage sludge use or disposal practices. Unless the sewage sludge meets the requirements of subdivision P 8 d of this section, the description must include the name and address of any facility where sewage sludge is sent for treatment or disposal and the location of any land application sites;
(4) Annual amount of sewage sludge generated, treated, used or disposed (estimated dry weight basis); and
(5) The most recent data the TWTDS may have on the quality of the sewage sludge.
c. Notwithstanding subdivision 2 a or b of this subsection, the board may require permit applications from any TWTDS at any time if the board determines that a permit is necessary to protect public health and the environment from any potential adverse effects that may occur from toxic pollutants in sewage sludge.
d. Any TWTDS that commences operations after promulgation of an applicable standard for sewage sludge use or disposal shall submit an application to the department at least 180 days prior to the date proposed for commencing operations.
D. Duty to reapply. All permittees with a currently effective permit shall submit a new application at least 180 days before the expiration date of the existing permit, unless permission for a later date has been granted by the board. The board shall not grant permission for applications to be submitted later than the expiration date of the existing permit.
E. Completeness.
1. The board shall not issue a permit before receiving a complete application for a permit except for VPDES general permits. An application for a permit is complete when the board receives an application form and any supplemental information which are completed to its satisfaction. The completeness of any application for a permit shall be judged independently of the status of any other permit application or permit for the same facility or activity.
2. No application for a VPDES permit to discharge sewage into or adjacent to state waters from a privately owned treatment works serving, or designed to serve, 50 or more residences shall be considered complete unless the applicant has provided the department with notification from the State Corporation Commission that the applicant is incorporated in the Commonwealth and is in compliance with all regulations and relevant orders of the State Corporation Commission.
3. No application for a new individual VPDES permit authorizing a new discharge of sewage, industrial wastes, or other wastes shall be considered complete unless it contains notification from the county, city, or town in which the discharge is to take place that the location and operation of the discharging facility are consistent with applicable ordinances adopted pursuant to Chapter 22 (§ 15.2-2200 et seq.) of Title 15.2 of the Code of Virginia. The county, city or town shall inform in writing the applicant and the board of the discharging facility's compliance or noncompliance not more than 30 days from receipt by the chief administrative officer, or his agent, of a request from the applicant. Should the county, city or town fail to provide such written notification within 30 days, the requirement for such notification is waived. The provisions of this subsection shall not apply to any discharge for which a valid VPDES permit had been issued prior to March 10, 2000.
4. A permit application shall not be considered complete if the board has waived application requirements under subsection J or P of this section and the EPA has disapproved the waiver application. If a waiver request has been submitted to the EPA more than 210 days prior to permit expiration and the EPA has not disapproved the waiver application 181 days prior to permit expiration, the permit application lacking the information subject to the waiver application shall be considered complete.
5. In accordance with § 62.1-44.19:3 A of the Code of Virginia, no application for a permit or variance to authorize the storage of sewage sludge shall be complete unless it contains certification from the governing body of the locality in which the sewage sludge is to be stored that the storage site is consistent with all applicable ordinances. The governing body shall confirm or deny consistency within 30 days of receiving a request for certification. If the governing body does not so respond, the site shall be deemed consistent.
F. Information requirements. All applicants for VPDES permits, other than POTWs and other TWTDS, shall provide the following information to the department, using the application form provided by the department (additional information required of applicants is set forth in subsections G through K of this section).
1. The activities conducted by the applicant which require it to obtain a VPDES permit;
2. Name, mailing address, and location of the facility for which the application is submitted;
3. Up to four SIC codes which best reflect the principal products or services provided by the facility;
4. The operator's name, address, telephone number, ownership status, and status as federal, state, private, public, or other entity;
5. Whether the facility is located on Indian lands;
6. A listing of all permits or construction approvals received or applied for under any of the following programs:

c. VPDES program under the CWA and the law;
d. Prevention of Significant Deterioration (PSD) program under the Clean Air Act (42 USC § 4701 et seq.);
e. Nonattainment program under the Clean Air Act (42 USC § 4701 et seq.);
f. National Emission Standards for Hazardous Pollutants (NESHAPS) preconstruction approval under the Clean Air Act (42 USC § 4701 et seq.);
g. Ocean dumping permits under the Marine Protection Research and Sanctuaries Act (33 USC § 14 et seq.);
h. Dredge or fill permits under § 404 of the CWA; and
i. Other relevant environmental permits, including state permits.
7. A topographic map (or other map if a topographic map is unavailable) extending one mile beyond the property boundaries of the source, depicting the facility and each of its intake and discharge structures; each of its hazardous waste treatment, storage, or disposal facilities; each well where fluids from the facility are injected underground; and those wells, springs, other surface water bodies, and drinking water wells listed in public records or otherwise known to the applicant in the map area; and
8. A brief description of the nature of the business.
G. Application requirements for existing manufacturing, commercial, mining, and silvicultural dischargers. Existing manufacturing, commercial mining, and silvicultural dischargers applying for VPDES permits, except for those facilities subject to the requirements of 9VAC25-31-100 H, shall provide the following information to the department, using application forms provided by the department.
1. The latitude and longitude of each outfall to the nearest 15 seconds and the name of the receiving water.
2. A line drawing of the water flow through the facility with a water balance, showing operations contributing wastewater to the effluent and treatment units. Similar processes, operations, or production areas may be indicated as a single unit, labeled to correspond to the more detailed identification under subdivision 3 of this subsection. The water balance must show approximate average flows at intake and discharge points and between units, including treatment units. If a water balance cannot be determined (for example, for certain mining activities), the applicant may provide instead a pictorial description of the nature and amount of any sources of water and any collection and treatment measures.
3. A narrative identification of each type of process, operation, or production area which contributes wastewater to the effluent for each outfall, including process wastewater, cooling water, and storm water run-off; the average flow which each process contributes; and a description of the treatment the wastewater receives, including the ultimate disposal of any solid or fluid wastes other than by discharge. Processes, operations, or production areas may be described in general terms (for example, dye-making reactor, distillation tower). For a privately owned treatment works, this information shall include the identity of each user of the treatment works. The average flow of point sources composed of storm water may be estimated. The basis for the rainfall event and the method of estimation must be indicated.
4. If any of the discharges described in subdivision 3 of this subsection are intermittent or seasonal, a description of the frequency, duration and flow rate of each discharge occurrence (except for storm water run-off, spillage or leaks).
5. If an effluent guideline promulgated under § 304 of the CWA applies to the applicant and is expressed in terms of production (or other measure of operation), a reasonable measure of the applicant's actual production reported in the units used in the applicable effluent guideline. The reported measure must reflect the actual production of the facility.
6. If the applicant is subject to any present requirements or compliance schedules for construction, upgrading or operation of waste treatment equipment, an identification of the abatement requirement, a description of the abatement project, and a listing of the required and projected final compliance dates.
7. a. Information on the discharge of pollutants specified in this subdivision (except information on storm water discharges which is to be provided as specified in 9VAC25-31-120). When quantitative data for a pollutant are required, the applicant must collect a sample of effluent and analyze it for the pollutant in accordance with analytical methods approved under 40 CFR Part 136 (2005). When no analytical method is approved the applicant may use any suitable method but must provide a description of the method. When an applicant has two or more outfalls with substantially identical effluents, the board may allow the applicant to test only one outfall and report that the quantitative data also apply to the substantially identical outfalls. The requirements in e and f of this subdivision that an applicant must provide quantitative data for certain pollutants known or believed to be present do not apply to pollutants present in a discharge solely as the result of their presence in intake water; however, an applicant must report such pollutants as present. Grab samples must be used for pH, temperature, cyanide, total phenols, residual chlorine, oil and grease, fecal coliform, and fecal streptococcus. For all other pollutants, 24-hour composite samples must be used. However, a minimum of one grab sample may be taken for effluents from holding ponds or other impoundments with a retention period greater than 24 hours. In addition, for discharges other than storm water discharges, the board may waive composite sampling for any outfall for which the applicant demonstrates that the use of an automatic sampler is infeasible and that the minimum of four grab samples will be a representative sample of the effluent being discharged.
b. For storm water discharges, all samples shall be collected from the discharge resulting from a storm event that is greater than 0.1 inch and at least 72 hours from the previously measurable (greater than 0.1 inch rainfall) storm event. Where feasible, the variance in the duration of the event and the total rainfall of the event should not exceed 50% from the average or median rainfall event in that area. For all applicants, a flow-weighted composite shall be taken for either the entire discharge or for the first three hours of the discharge. The flow-weighted composite sample for a storm water discharge may be taken with a continuous sampler or as a combination of a minimum of three sample aliquots taken in each hour of discharge for the entire discharge or for the first three hours of the discharge, with each aliquot being separated by a minimum period of 15 minutes (applicants submitting permit applications for storm water discharges under 9VAC25-31-120 C may collect flow-weighted composite samples using different protocols with respect to the time duration between the collection of sample aliquots, subject to the approval of the board). However, a minimum of one grab sample may be taken for storm water discharges from holding ponds or other impoundments with a retention period greater than 24 hours. For a flow-weighted composite sample, only one analysis of the composite of aliquots is required. For storm water discharge samples taken from discharges associated with industrial activities, quantitative data must be reported for the grab sample taken during the first 30 minutes (or as soon thereafter as practicable) of the discharge for all pollutants specified in 9VAC25-31-120 B 1. For all storm water permit applicants taking flow-weighted composites, quantitative data must be reported for all pollutants specified in 9VAC25-31-120 except pH, temperature, cyanide, total phenols, residual chlorine, oil and grease, fecal coliform, and fecal streptococcus. The board may allow or establish appropriate site-specific sampling procedures or requirements, including sampling locations, the season in which the sampling takes place, the minimum duration between the previous measurable storm event and the storm event sampled, the minimum or maximum level of precipitation required for an appropriate storm event, the form of precipitation sampled (snow melt or rain fall), protocols for collecting samples under 40 CFR Part 136 (2005), and additional time for submitting data on a case-by-case basis. An applicant is expected to know or have reason to believe that a pollutant is present in an effluent based on an evaluation of the expected use, production, or storage of the pollutant, or on any previous analyses for the pollutant. (For example, any pesticide manufactured by a facility may be expected to be present in contaminated storm water run-off from the facility.)
c. Every applicant must report quantitative data for every outfall for the following pollutants:
Biochemical oxygen demand (BOD5)
Chemical oxygen demand
Total organic carbon
Total suspended solids
Ammonia (as N)
Temperature (both winter and summer)
pH
d. The board may waive the reporting requirements for individual point sources or for a particular industry category for one or more of the pollutants listed in subdivision 7 c of this subsection if the applicant has demonstrated that such a waiver is appropriate because information adequate to support issuance of a permit can be obtained with less stringent requirements.
e. Each applicant with processes in one or more primary industry category (see 40 CFR Part 122 Appendix A (2005)) contributing to a discharge must report quantitative data for the following pollutants in each outfall containing process wastewater:
(1) The organic toxic pollutants in the fractions designated in Table I of 40 CFR Part 122 Appendix D (2005) for the applicant's industrial category or categories unless the applicant qualifies as a small business under subdivision 8 of this subsection. Table II of 40 CFR Part 122 Appendix D (2005) lists the organic toxic pollutants in each fraction. The fractions result from the sample preparation required by the analytical procedure which uses gas chromatography/mass spectrometry. A determination that an applicant falls within a particular industrial category for the purposes of selecting fractions for testing is not conclusive as to the applicant's inclusion in that category for any other purposes; and
(2) The pollutants listed in Table III of 40 CFR Part 122 Appendix D (2005) (the toxic metals, cyanide, and total phenols).
f. (1) Each applicant must indicate whether it knows or has reason to believe that any of the pollutants in Table IV of 40 CFR Part 122 Appendix D (2005) (certain conventional and nonconventional pollutants) is discharged from each outfall. If an applicable effluent limitations guideline either directly limits the pollutant or, by its express terms, indirectly limits the pollutant through limitations on an indicator, the applicant must report quantitative data. For every pollutant discharged which is not so limited in an effluent limitations guideline, the applicant must either report quantitative data or briefly describe the reasons the pollutant is expected to be discharged.
(2) Each applicant must indicate whether it knows or has reason to believe that any of the pollutants listed in Table II or Table III of 40 CFR Part 122 Appendix D (2005) (the toxic pollutants and total phenols) for which quantitative data are not otherwise required under subdivision 7 e of this subsection, is discharged from each outfall. For every pollutant expected to be discharged in concentrations of 10 ppb or greater the applicant must report quantitative data. For acrolein, acrylonitrile, 2,4 dinitrophenol, and 2-methyl-4,6 dinitrophenol, where any of these four pollutants are expected to be discharged in concentrations of 100 ppb or greater the applicant must report quantitative data. For every pollutant expected to be discharged in concentrations less than 10 ppb, or in the case of acrolein, acrylonitrile, 2,4 dinitrophenol, and 2-methyl-4,6 dinitrophenol, in concentrations less than 100 ppb, the applicant must either submit quantitative data or briefly describe the reasons the pollutant is expected to be discharged. An applicant qualifying as a small business under subdivision 8 of this subsection is not required to analyze for pollutants listed in Table II of 40 CFR Part 122 Appendix D (2005) (the organic toxic pollutants).
g. Each applicant must indicate whether it knows or has reason to believe that any of the pollutants in Table V of 40 CFR Part 122 Appendix D (2005) (certain hazardous substances and asbestos) are discharged from each outfall. For every pollutant expected to be discharged, the applicant must briefly describe the reasons the pollutant is expected to be discharged, and report any quantitative data it has for any pollutant.
h. Each applicant must report qualitative data, generated using a screening procedure not calibrated with analytical standards, for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) if it:
(1) Uses or manufactures 2,4,5-trichlorophenoxy acetic acid (2,4,5,-T); 2-(2,4,5-trichlorophenoxy) propanoic acid (Silvex, 2,4,5,-TP); 2-(2,4,5-trichlorophenoxy) ethyl, 2,2-dichloropropionate (Erbon); O,O-dimethyl O-(2,4,5-trichlorophenyl) phosphorothioate (Ronnel); 2,4,5-trichlorophenol (TCP); or hexachlorophene (HCP); or
(2) Knows or has reason to believe that TCDD is or may be present in an effluent.
8. An applicant which qualifies as a small business under one of the following criteria is exempt from the requirements in subdivision 7 e (1) or 7 f (1) of this subsection to submit quantitative data for the pollutants listed in Table II of 40 CFR Part 122 Appendix D (2005) (the organic toxic pollutants):
a. For coal mines, a probable total annual production of less than 100,000 tons per year; or
b. For all other applicants, gross total annual sales averaging less than $100,000 per year (in second quarter 1980 dollars).
9. A listing of any toxic pollutant which the applicant currently uses or manufactures as an intermediate or final product or byproduct. The board may waive or modify this requirement for any applicant if the applicant demonstrates that it would be unduly burdensome to identify each toxic pollutant and the board has adequate information to issue the permit.
10. Reserved.
11. An identification of any biological toxicity tests which the applicant knows or has reason to believe have been made within the last three years on any of the applicant's discharges or on a receiving water in relation to a discharge.
12. If a contract laboratory or consulting firm performed any of the analyses required by subdivision 7 of this subsection, the identity of each laboratory or firm and the analyses performed.
13. In addition to the information reported on the application form, applicants shall provide to the board, at its request, such other information, including pertinent plans, specifications, maps and such other relevant information as may be required, in scope and details satisfactory to the board, as the board may reasonably require to assess the discharges of the facility and to determine whether to issue a VPDES permit. The additional information may include additional quantitative data and bioassays to assess the relative toxicity of discharges to aquatic life and requirements to determine the cause of the toxicity.
H. Application requirements for manufacturing, commercial, mining and silvicultural facilities which discharge only nonprocess wastewater. Except for storm water discharges, all manufacturing, commercial, mining and silvicultural dischargers applying for VPDES permits which discharge only nonprocess wastewater not regulated by an effluent limitations guideline or new source performance standard shall provide the following information to the department using application forms provided by the department:
1. Outfall number, latitude and longitude to the nearest 15 seconds, and the name of the receiving water;
2. Date of expected commencement of discharge;

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

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

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

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

Disposal of sewage sludge in a municipal solid waste landfill unit that complies with the requirements in the Virginia Solid Waste Management Regulation (9VAC20-80-10 et seq.) Regulations (9VAC20-81) constitutes compliance with § 405(d) of the CWA. Any person who prepares sewage sludge that is disposed in a municipal solid waste landfill unit shall ensure that the sewage sludge meets the requirements in 9VAC20-80-10 et seq. 9VAC20-81 concerning the quality of materials disposed in a municipal solid waste landfill unit.
9VAC25-31-790. Removal credits.
A. General.
1. Definitions for the purpose of this section:
"Removal" means a reduction in the amount of a pollutant in the POTW's effluent or alteration of the nature of a pollutant during treatment at the POTW. The reduction or alteration can be obtained by physical, chemical or biological means and may be the result of specifically designed POTW capabilities or may be incidental to the operation of the treatment system. Removal as used in this subpart shall not mean dilution of a pollutant in the POTW.
"Sludge requirements" means the following statutory provisions and regulations or permits issued thereunder (or more stringent Virginia or local regulations): § 405 of the CWA; the Solid Waste Disposal Act (SWDA) (42 USC § 6901 et seq.) (including Title II more commonly referred to as the Resource Conservation Recovery Act (RCRA) (42 USC § 6901 et seq.) and Virginia regulations contained in any Virginia sludge management plan prepared pursuant to Subtitle D of SWDA); the Clean Air Act (42 USC § 4701 et seq.); the Toxic Substances Control Act (15 USC § 2601 et seq.); and the Marine Protection, Research and Sanctuaries Act (33 USC § 1401 et seq.).
2. General. Any POTW receiving wastes from an industrial user to which a categorical pretreatment standards applies may, at its discretion and subject to the conditions of this section, grant removal credits to reflect removal by the POTW of pollutants specified in the categorical pretreatment standards. The POTW may grant a removal credit equal to or, at its discretion, less than its consistent removal rate. Upon being granted a removal credit, each affected industrial user shall calculate its revised discharge limits in accordance with subdivision 4 of this subsection. Removal credits may only be given for indicator or surrogate pollutants regulated in a categorical pretreatment standard if the categorical pretreatment statement so specifies.
3. Conditions for authorization to give removal credits. A POTW is authorized to give removal credits only if the following conditions are met;
a. Application. The POTW applies for, and receives, authorization from the director to give a removal credit in accordance with the requirements and procedures specified in subsection E of this section;
b. Consistent removal determination. The POTW demonstrates and continues to achieve consistent removal of the pollutant in accordance with subsection B of this section;
c. POTW local pretreatment program. The POTW has an approved pretreatment program in accordance with and to the extent required by this part; provided, however, a POTW which does not have an approved pretreatment program may, pending approval of such a program, conditionally give credits as provided in subsection D of this section;
d. Sludge requirements. The granting of removal credits will not cause the POTW to violate the local, state and federal sludge requirements which apply to the sludge management method chosen by the POTW. Alternatively, the POTW can demonstrate to the director that even though it is not presently in compliance with applicable sludge requirements, it will be in compliance when the industrial users to whom the removal credit would apply is required to meet its categorical pretreatment standards as modified by the removal credit. If granting removal credits forces a POTW to incur greater sludge management costs than would be incurred in the absence of granting removal costs, the additional sludge management costs will not be eligible for EPA grant assistance. Removal credits may be made available for the following pollutants:
(1) For any pollutant listed in Appendix G-I of the regulation incorporated by reference in 9VAC25-31-750 for the use or disposal practice employed by the POTW, when the requirements of Part VI of this chapter for that practice are met;
(2) For any pollutant listed in Appendix G-II of the regulation incorporated by reference in 9VAC25-31-750 for the use or disposal practice employed by the POTW when the concentration for a pollutant listed in Appendix G-II of the regulation incorporated by reference in 9VAC25-31-750 in the sewage sludge that is used or disposed does not exceed the concentration for the pollutant in Appendix G-II of the regulation incorporated by reference in 9VAC25-31-750; and
(3) For any pollutant in sewage sludge when the POTW disposes all of its sewage sludge in a municipal solid waste landfill that meets the criteria in the Code of Virginia and the Solid Waste Management Regulation, 9VAC20-80 Regulations, 9VAC20-81;
e. VPDES permit limitations. The granting of removal credits will not cause a violation of the POTW's permit limitations or conditions. Alternatively, the POTW can demonstrate to the director that even though it is not presently in compliance with applicable limitations and conditions in its VPDES permit, it will be in compliance when the industrial user or users to whom the removal credit would apply is required to meet its categorical pretreatment standard or standards, as modified by the removal credit provision.
4. Calculation of revised discharge limits. Revised discharge limits for a specific pollutant shall be derived by use of the following formula:
where:
x = pollutant discharge limit specified in the applicable categorical pretreatment standard
r = removal credit for that pollutant as established under subsection B of this section (percentage removal expressed as a proportion, i.e., a number between 0 and 1)
y = revised discharge limit for the specified pollutant (expressed in same units as x)
B. Establishment of removal credits; demonstration of consistent removal.
1. Definition of "consistent removal." "Consistent removal" means the average of the lowest 50% of the removal measured according to subdivision 2 of this subsection. All sample data obtained for the measured pollutant during the time period prescribed in subdivision 2 of this subsection must be reported and used in computing consistent removal. If a substance is measurable in the influent but not in the effluent, the effluent level may be assumed to be the limit of measurement, and those data may be used by the POTW at its discretion and subject to approval by the director. If the substance is not measurable in the influent, the data may not be used. Where the number of samples with concentrations equal to or above the limit of measurement is between eight and 12, the average of the lowest six removals shall be used. If there are less than eight samples with concentrations equal to or above the limit of measurement, the director may approve alternate means for demonstrating consistent removal. The term "measurement" refers to the ability of the analytical method or protocol to quantify as well as identify the presence of the substance in question.
2. Consistent removal data. Influent and effluent operational data demonstrating consistent removal or other information, as provided for in subdivision 1 of this subsection, which demonstrates consistent removal of the pollutants for which discharge limit revisions are proposed. This data shall meet the following requirements:
a. Representative data; seasonal. The data shall be representative of yearly and seasonal conditions to which the POTW is subjected for each pollutant for which a discharge limit revision is proposed;
b. Representative data; quality and quantity. The data shall be representative of the quality and quantity of normal effluent and influent flow if such data can be obtained. If such data are unobtainable, alternate data or information may be presented for approval to demonstrate consistent removal as provided for in subdivision 1 of this subsection;
c. Sampling procedures: composite.
(1) The influent and effluent operational data shall be obtained through 24-hour flow-proportional composite samples. Sampling may be done manually or automatically, and discretely or continuously. For discrete sampling, at least 12 aliquots shall be composited. Discrete sampling may be flow-proportioned either by varying the time interval between each aliquot or the volume of each aliquot. All composites must be flow proportional to each stream flow at time of collection of influent aliquot or to the total influent flow since the previous influent aliquot. Volatile pollutant aliquots must be combined in the laboratory immediately before analysis.
(2)(a) Twelve samples shall be taken at approximately equal intervals throughout one full year. Sampling must be evenly distributed over the days of the week so as to include no-workdays as well as workdays. If the director determines that this schedule will not be most representative of the actual operation of the POTW treatment plant, an alternative sampling schedule will be approved.
(b) In addition, upon the director's concurrence, a POTW may utilize an historical data base amassed prior to July 24, 1996, provide that such data otherwise meet the requirements of this paragraph. In order for the historical data base to be approved it must present a statistically valid description of daily, weekly and seasonal sewage treatment plant loadings and performance for at least one year.
(3) Effluent sample collection need not be delayed to compensate for hydraulic detention unless the POTW elects to include detention time compensation or unless the director requires detention time compensation. The director may require that each effluent sample be taken approximately one detention time later than the corresponding influent sample when failure to do so would result in an unrepresentative portrayal of actual POTW operation. The detention period is to be based on a 24-hour average daily flow value. The average daily flow used will be based upon the average of the daily flows during the same month of the previous year.
d. Sampling procedures: Grab. Where composite sampling is not an appropriate sampling technique, a grab sample or samples shall be taken to obtain influent and effluent operational data. Collection of influent grab samples should precede collection of effluent samples by approximately one detention period. The detention period is to be based on a 24-hour average daily flow value. The average daily flow used will be based upon the average of the daily flows during the same month of the previous year. Grab samples will be required, for example, where the parameters being evaluated are those, such as cyanide and phenol, which may not be held for any extended period because of biological, chemical or physical interactions which take place after sample collection and affect the results. A grab sample is an individual sample collected over a period of time not exceeding 15 minutes;
e. Analytical methods. The sampling referred to in subdivisions 2 a through d of this subsection and an analysis of these samples shall be performed in accordance with the techniques prescribed in 40 CFR Part 136 (2005) and amendments thereto. Where 40 CFR Part 136 (2005) does not contain sampling or analytical techniques for the pollutant in question, or where the administrator determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analysis shall be performed using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the POTW or other parties, approved by the administrator; and
f. Calculation of removal. All data acquired under the provisions of this section must be submitted to the department. Removal for a specific pollutant shall be determined either, for each sample, by measuring the difference between the concentrations of the pollutant in the influent and effluent of the POTW and expressing the difference as a percentage of the influent concentration, or, where such data cannot be obtained, removal may be demonstrated using other data or procedures subject to concurrence by the director as provided for in subdivision 1 of this subsection.
C. Provisional credits. For pollutants which are not being discharged currently (i.e., new or modified facilities, or production changes) the POTW may apply for authorization to give removal credits prior to the initial discharge of the pollutant. Consistent removal shall be based provisionally on data from treatability studies or demonstrated removal at other treatment facilities where the quality and quantity of influent are similar. Within 18 months after the commencement of discharge of pollutants in question, consistent removal must be demonstrated pursuant to the requirements of subsection B of this section. If, within 18 months after the commencement of the discharge of the pollutant in question, the POTW cannot demonstrate consistent removal pursuant to the requirements of subsection B of this section, the authority to grant provisional removal credits shall be terminated by the director and all industrial users to whom the revised discharge limits had been applied shall achieve compliance with the applicable categorical pretreatment standards within a reasonable time, not to exceed the period of time prescribed in the applicable categorical pretreatment standards, as may be specified by the director.
D. Exception to POTW pretreatment program requirement. A POTW required to develop a local pretreatment program by 9VAC25-31-800 may conditionally give removal credits pending approval of such a program in accordance with the following terms and conditions:
1. All industrial users who are currently subject to a categorical pretreatment standard and who wish conditionally to receive a removal credit must submit to the POTW the information required in 9VAC25-31-840 B 1 through 7 (except new or modified industrial users must only submit the information required by 9VAC25-31-840 B 1 through 6), pertaining to the categorical pretreatment standard as modified by the removal credit. The industrial users shall indicate what additional technology, if any, will be needed to comply with the categorical pretreatment standard or standards as modified by the removal credit;
2. The POTW must have submitted to the department an application for pretreatment program approval meeting the requirements of 9VAC25-31-800 and 9VAC25-31-810 in a timely manner, not to exceed the time limitation set forth in a compliance schedule for development of a pretreatment program included in the POTW's VPDES permit, but in no case later than July 1, 1983, where no permit deadline exists;
3. The POTW must:
a. Compile and submit data demonstrating its consistent removal in accordance with subsection B of this section;
b. Comply with the conditions specified in subdivision A 3 of this section; and
c. Submit a complete application for removal credit authority in accordance with subsection E of this section;
4. If a POTW receives authority to grant conditional removal credits and the director subsequently makes a final determination, after appropriate notice, that the POTW failed to comply with the conditions in subdivisions 2 and 3 of this subsection, the authority to grant conditional removal credits shall be terminated by the director and all industrial users to whom the revised discharge limits had been applied shall achieve compliance with the applicable categorical pretreatment standards within a reasonable time, not to exceed the period of time prescribed in the applicable categorical pretreatment standards, as may be specified by the director;
5. If a POTW grants conditional removal credits and the POTW or the director subsequently makes a final determination, after appropriate notice, that the industrial user or users failed to comply with the conditions in subdivision 1 of this subsection, the conditional credit shall be terminated by the POTW or the director for the noncomplying industrial user or users and the industrial user or users to whom the revised discharge limits had been applied shall achieve compliance with the applicable categorical pretreatment standards within a reasonable time, not to exceed the period of time prescribed in the applicable categorical pretreatment standards, as may be specified by the director. The conditional credit shall not be terminated where a violation of the provisions of this paragraph results from causes entirely outside of the control of the industrial user or users or the industrial user or users had demonstrated subsequential compliance; and
6. The director may elect not to review an application for conditional removal credit authority upon receipt of such application, in which case the conditionally revised discharge limits will remain in effect until reviewed by the director. This review may occur at any time in accordance with the procedures of 9VAC25-31-830, but in no event later than the time of any pretreatment program approval or any VPDES permit reissuance thereunder.
E. POTW application for authorization to give removal credits and director review.
1. Who must apply. Any POTW that wants to give a removal credit must apply for authorization from the director.
2. To whom application is made. An application for authorization to give removal credits (or modify existing ones) shall be submitted by the POTW to the department.
3. When to apply. A POTW may apply for authorization to give or modify removal credits at any time.
4. Contents of the application. An application for authorization to give removal credits must be supported by the following information:
a. List of pollutants. A list of pollutants for which removal credits are proposed;
b. Consistent removal data. The data required pursuant to subsection B of this section;
c. Calculation of revised discharge limits. Proposed revised discharge limits for each affected subcategory of industrial users calculated in accordance with subdivision A 4 of this section;
d. Local pretreatment program certification. A certification that the POTW has an approved local pretreatment program or qualifies for the exception to this requirement found at subsection D of this section;
e. Sludge management certification. A specific description of the POTW's current methods of using or disposing of its sludge and a certification that the granting of removal credits will not cause a violation of the sludge requirements identified in subdivision A 3 d of this section; and
f. VPDES permit limit certification. A certification that the granting of removal credits will not cause a violation of the POTW's VPDES permit limits and conditions as required in subdivision A 3 e of this section.
5. Director review. The director shall review the POTW's application for authorization to give or modify removal credits in accordance with the procedures of 9VAC25-31-830 and shall, in no event, have more than 180 days from public notice of an application to complete review.
6. Nothing in this part precludes an industrial user or other interested party from assisting the POTW in preparing and presenting the information necessary to apply for authorization.
F. Continuation and withdrawal of authorization.
1. Effect of authorization. Once a POTW has received authorization to grant removal credits for a particular pollutant regulated in a categorical pretreatment standard it may automatically extend that removal credit to the same pollutant when it is regulated in other categorical standards, unless granting the removal credit will cause the POTW to violate the sludge requirements identified in subdivision A 3 d of this section or its VPDES permit limits and conditions as required by subdivision A 3 e of this section. If a POTW elects at a later time to extend removal credits to a certain categorical pretreatment standard, industrial subcategory or one or more industrial users that initially were not granted removal credits, it must notify the department.
2. Inclusion in POTW permit. Once authority is granted, the removal credits shall be included in the POTW's VPDES permit as soon as possible and shall become an enforceable requirement of the POTW's VPDES permit. The removal credits will remain in effect for the term of the POTW's VPDES permit, provided the POTW maintains compliance with the conditions specified in subdivision 4 of this subsection.
3. Compliance monitoring. Following authorization to give removal credits, a POTW shall continue to monitor and report on (at such intervals as may be specified by the director, but in no case less than once per year) the POTW's removal capabilities. A minimum of one representative sample per month during the reporting period is required, and all sampling data must be included in the POTW's compliance report.
4. Modification or withdrawal of removal credits.
a. Notice of POTW. The director shall notify the POTW if, on the basis of pollutant removal capability reports received pursuant to subdivision 3 of this subsection or other relevant information available to it, the director determines:
(1) That one or more of the discharge limit revisions made by the POTW, of the POTW itself, no longer meets the requirements of this section, or
(2) That such discharge limit revisions are causing a violation of any conditions or limits contained in the POTW's VPDES Permit.
b. Corrective action. If appropriate corrective action is not taken within a reasonable time, not to exceed 60 days unless the POTW or the affected industrial users demonstrate that a longer time period is reasonably necessary to undertake the appropriate corrective action, the director shall either withdraw such discharge limits or require modifications in the revised discharge limits.
c. Public notice of withdrawal or modification. The director shall not withdraw or modify revised discharge limits unless it shall first have notified the POTW and all industrial users to whom revised discharge limits have been applied, and made public, in writing, the reasons for such withdrawal or modification, and an opportunity is provided for a public hearing. Following such notice and withdrawal or modification, all industrial users to whom revised discharge limits had been applied, shall be subject to the modified discharge limits or the discharge limits prescribed in the applicable categorical pretreatment standards, as appropriate, and shall achieve compliance with such limits within a reasonable time (not to exceed the period of time prescribed in the applicable categorical pretreatment standards) as may be specified by the director.
G. Removal credits in state-run pretreatment programs. Where the director elects to implement a local pretreatment program in lieu of requiring the POTW to develop such a program the POTW will not be required to develop a pretreatment program as a precondition to obtaining authorization to give removal credits. The POTW will, however, be required to comply with the other conditions of subdivision A 3 of this section.
H. Compensation for overflow. For the purpose of this section, "overflow" means the intentional or unintentional diversion of flow from the POTW before the POTW treatment plant. POTWs which at least once annually overflow untreated wastewater to receiving waters may claim consistent removal of a pollutant only by complying with either subdivision 1 or 2 of this subsection. However, this subsection shall not apply where industrial users can demonstrate that overflow does not occur between the industrial users and the POTW treatment plant:
1. The industrial user provides containment or otherwise ceases or reduces discharges from the regulated processes which contain the pollutant for which an allowance is requested during all circumstances in which an overflow event can reasonably be expected to occur at the POTW or at a sewer to which the industrial user is connected. Discharges must cease or be reduced, or pretreatment must be increased, to the extent necessary to compensate for the removal not being provided by the POTW. Allowances under this provision will only be granted where the POTW submits to the department evidence that:
a. All industrial users to which the POTW proposes to apply this provision have demonstrated the ability to contain or otherwise cease or reduce, during circumstances in which an overflow event can reasonably be expected to occur, discharges from the regulated processes which contain pollutants for which an allowance is requested;
b. The POTW has identified circumstances in which an overflow event can reasonably be expected to occur, and has a notification or other viable plan to insure that industrial users will learn of an impending overflow in sufficient time to contain, cease or reduce discharging to prevent untreated overflows from occurring. The POTW must also demonstrate that it will monitor and verify the data required in subdivision 1 c of this subsection, to insure that industrial users are containing, ceasing or reducing operations during POTW system overflow; and
c. All industrial users to which the POTW proposes to apply this provision have demonstrated the ability and commitment to collect and make available, upon request by the POTW, the director or EPA Regional Administrator, daily flow reports or other data sufficient to demonstrate that all discharges from regulated processes containing the pollutant for which the allowance is requested were contained, reduced or otherwise ceased, as appropriate, during all circumstances in which an overflow event was reasonably expected to occur; or
2. a. The consistent removal claimed is reduced pursuant to the following equation:
where:
rm = POTW's consistent removal rate for that pollutant as established under subsections A 1 and B 2 of this section
rc = removal corrected by the overflow factor
Z = hours per year that overflow occurred between the industrial user or users and the POTW treatment plant, the hours either to be shown in the POTW's current VPDES permit application or the hours, as demonstrated by verifiable techniques, that a particular industrial user's discharge overflows between the industrial user and the POTW treatment plant.
b. The POTW is complying with all VPDES permit requirements and any additional requirements in any order or decree, issued pursuant to the Clean Water Act affecting combined sewer outflows. These requirements include, but are not limited to, any combined sewer overflow requirements that conform to the Combined Sewer Overflow Control Policy.
9VAC25-151-190. Sector L - Landfills, land application sites and open dumps.
A. Discharges covered under this section. The requirements listed under this section apply to storm water discharges associated with industrial activity from waste disposal at landfills, land application sites, and open dumps that receive or have received industrial wastes (Industrial Activity Code "LF"), including sites subject to regulation under Subtitle D of RCRA. Open dumps are solid waste disposal units that are not in compliance with state/federal criteria established under RCRA Subtitle D. Landfills, land application sites, and open dumps that have storm water discharges from other types of industrial activities such as vehicle maintenance, truck washing, and/or recycling may be subject to additional requirements specified elsewhere in this permit.
B. Special conditions. Prohibition of nonstorm water discharges. In addition to the general nonstorm water prohibition in Part I B 1, the following discharges are not covered by this permit: leachate, gas collection condensate, drained free liquids, contaminated ground water, laboratory wastewater, and contact washwater from washing truck and railcar exteriors and surface areas that have come in direct contact with solid waste at the landfill facility.
C. Definitions.
"Contaminated storm water" means storm water that comes in direct contact with landfill wastes, the waste handling and treatment areas, or landfill wastewater as defined below. Some specific areas of a landfill that may produce contaminated storm water include, but are not limited to: the open face of an active landfill with exposed waste (no cover added); the areas around wastewater treatment operations; trucks, equipment or machinery that has been in direct contact with the waste; and waste dumping areas.
"Drained free liquids" means aqueous wastes drained from waste containers (e.g., drums, etc.) prior to landfilling.
"Landfill wastewater" as defined in 40 CFR Part 445 (2007) (Landfills Point Source Category) means all wastewater associated with, or produced by, landfilling activities except for sanitary wastewater, noncontaminated storm water, contaminated groundwater, and wastewater from recovery pumping wells. Landfill process wastewater includes, but is not limited to, leachate, gas collection condensate, drained free liquids, laboratory derived wastewater, contaminated storm water and contact washwater from washing truck, equipment, and railcar exteriors and surface areas that have come in direct contact with solid waste at the landfill facility.
"Leachate" means liquid that has passed through or emerged from solid waste and contains soluble, suspended, or miscible materials removed from such waste.
"Noncontaminated storm water" means storm water that does not come into direct contact with landfill wastes, the waste handling and treatment areas, or landfill wastewater as defined above. Noncontaminated storm water includes storm water that flows off the cap, cover, intermediate cover, daily cover, and/or final cover of the landfill.
D. Storm water pollution prevention plan requirements. In addition to the requirements in Part III, the SWPPP shall include, at a minimum, the following items.
1. Site description.
a. Site map. The site map shall identify where any of the following may be exposed to precipitation/surface runoff: active and closed landfill cells or trenches; active and closed land application areas; locations where open dumping is occurring or has occurred; locations of any known leachate springs or other areas where uncontrolled leachate may commingle with runoff; and leachate collection and handling systems.
b. Summary of potential pollutant sources. The SWPPP shall also include a description of potential pollutant sources associated with any of the following: fertilizer, herbicide and pesticide application; earth/soil moving; waste hauling and loading/unloading; outdoor storage of significant materials including daily, interim and final cover material stockpiles as well as temporary waste storage areas; exposure of active and inactive landfill and land application areas; uncontrolled leachate flows; and failure or leaks from leachate collection and treatment systems.
2. Storm water controls.
a. Preventive maintenance program. As part of the preventive maintenance program, the permittee shall maintain: all containers used for outdoor chemical/significant materials storage to prevent leaking; all elements of leachate collection and treatment systems to prevent commingling of leachate with storm water; and the integrity and effectiveness of any intermediate or final cover (including making repairs to the cover as necessary to minimize the effects of settlement, sinking, and erosion).
b. Good housekeeping measures. As part of the good housekeeping program, the permittee shall consider providing protected storage areas for pesticides, herbicides, fertilizer and other significant materials.
c. Routine facility inspections.
(1) Inspections of active sites. Operating landfills, open dumps, and land application sites shall be inspected at least once every seven days. Qualified personnel shall inspect areas of landfills that have not yet been finally stabilized, active land application areas, areas used for storage of materials/wastes that are exposed to precipitation, stabilization and structural control measures, leachate collection and treatment systems, and locations where equipment and waste trucks enter and exit the site. Erosion and sediment control measures shall be observed to ensure they are operating correctly. For stabilized sites and areas where land application has been completed, or where the climate is seasonally arid (annual rainfall averages from 0 to 10 inches) or semi-arid (annual rainfall averages from 10 to 20 inches), inspections shall be conducted at least once every month.
(2) Inspections of inactive sites. Inactive landfills, open dumps, and land application sites shall be inspected at least quarterly. Qualified personnel shall inspect landfill (or open dump) stabilization and structural erosion control measures and leachate collection and treatment systems, and all closed land application areas.
d. Recordkeeping and internal reporting procedures. Landfill and open dump owners shall provide for a tracking system for the types of wastes disposed of in each cell or trench of a landfill or open dump. Land application site owners shall track the types and quantities of wastes applied in specific areas.
e. Certification of outfall evaluation for unauthorized discharges. The discharge test and certification shall also be conducted for the presence of leachate and vehicle washwater.
f. Sediment and erosion control plan. Landfill and open dump owners shall provide for temporary stabilization of materials stockpiled for daily, intermediate, and final cover. Stabilization practices to consider include, but are not limited to, temporary seeding, mulching, and placing geotextiles on the inactive portions of the stockpiles. Landfill and open dump owners shall provide for temporary stabilization of inactive areas of the landfill or open dump which have an intermediate cover but no final cover. Landfill and open dump owners shall provide for temporary stabilization of any landfill or open dumping areas which have received a final cover until vegetation has established itself. Land application site owners shall also stabilize areas where waste application has been completed until vegetation has been established.
g. Comprehensive site compliance evaluation. Areas contributing to a storm water discharge associated with industrial activities at landfills, open dumps and land application sites shall be evaluated for evidence of, or the potential for, pollutants entering the drainage system.
E. Numeric effluent limitations. As set forth at 40 CFR Part 445 Subpart B (2007), the numeric limitations in Table 190-1 apply to contaminated storm water discharges from municipal solid waste landfills (MSWLFs) that have not been closed in accordance with 40 CFR 258.60 (2006), and contaminated storm water discharges from those landfills that are subject to the provisions of 40 CFR Part 257 (2006) (these include CDD landfills (also known as C&D landfills), and industrial landfills) except for discharges from any of the facilities described in subdivisions 1 through 4 of this subsection:
1. Landfills operated in conjunction with other industrial or commercial operations when the landfill only receives wastes generated by the industrial or commercial operation directly associated with the landfill;
2. Landfills operated in conjunction with other industrial or commercial operations when the landfill receives wastes generated by the industrial or commercial operation directly associated with the landfill and also receives other wastes provided the other wastes received for disposal are generated by a facility that is subject to the same provisions in 40 CFR Subchapter N (2007) as the industrial or commercial operation or the other wastes received are of similar nature to the wastes generated by the industrial or commercial operation;
3. Landfills operated in conjunction with centralized waste treatment (CWT) facilities subject to 40 CFR Part 437 (2007) so long as the CWT facility commingles the landfill wastewater with other nonlandfill wastewater for discharge. A landfill directly associated with a CWT facility is subject to this part if the CWT facility discharges landfill wastewater separately from other CWT wastewater or commingles the wastewater from its landfill only with wastewater from other landfills; or
4. Landfills operated in conjunction with other industrial or commercial operations when the landfill receives wastes from public service activities so long as the company owning the landfill does not receive a fee or other remuneration for the disposal service.

TITLE 9. ENVIRONMENT
STATE WATER CONTROL BOARD
Final Regulation
REGISTRAR'S NOTICE: The following regulatory action is exempt from the Administrative Process Act in accordance with § 2.2-4006 A 4 b of the Code of Virginia, which excludes regulations that are required by order of any state or federal court of competent jurisdiction where no agency discretion is involved. The State Water Control Board will receive, consider, and respond to petitions by any interested person at any time with respect to reconsideration or revision.
Title of Regulation: 9VAC25-720. Water Quality Management Planning Regulation (amending 9VAC25-720-50).
Statutory Authority: § 62.1-44.15 of the Code of Virginia; § 1313(e) of the Clean Water Act.
Effective Date: September 28, 2011.
Agency Contact: John Kennedy, Department of Environmental Quality, 629 East Main Street, P.O. Box 10009, Richmond, VA 23240, telephone (804) 698-4312, or email john.kennedy@deq.virginia.gov.
Background: At its April 27, 2009, meeting, the State Water Control Board approved amendments to the Water Quality Management Planning Regulation (9VAC25-720) that increased nutrient waste load allocations for Merck, Inc., a discharger in the Potomac-Shenandoah basin. The approved increases were as follows:
- Total Nitrogen increase from 14,619 lbs/yr to 43,835 lbs/yr
- Total Phosphorus increase from 1,096 lbs/yr to 4,384 lbs/yr
In June 2009 the Chesapeake Bay Foundation and Virginia Waterman's Association filed an appeal with the Richmond Circuit Court contesting this action. The parties involved have agreed to settle the case according to the terms set out in a Consent Decree entered with the court on April 27, 2011. Most notable among the terms of the decree was an order by the court that provides that "The Board shall forthwith amend its Water Quality Management Planning Regulation, 9 VAC 25-720-50, as shown in Exhibit A."
The amended waste load allocations in Exhibit A of the decree are the same as the revisions approved by the State Water Control Board on April 27, 2009. In addition, Exhibit A modified the footnote that accompanies the Merck allocations.
Summary:
According to a judicial consent decree entered April 27, 2011, in the Richmond Circuit Court, the amendments revise the nutrient waste load allocations for Merck, Inc. (VPDES VA0002178) by increasing discharges of total nitrogen to 43,835 lbs/yr and of total phosphorus to 4,384 lbs/yr. Additionally, amendments to footnote 10 detail Merck’s responsibilities for implementation and possible future actions under the Chesapeake Bay Total Maximum Daily Load approved by the Environmental Protection Agency in December 2010.

Summary:
This final action readopts and amends a Virginia Pollutant Discharge Elimination System (VPDES) general permit for discharges from pesticides applied directly to surface waters to control pests or applied to control pests that are present in or over, including near, surface waters. The general permit regulation is needed in order to comply with court-ordered requirements for the Environmental Protection Agency and states to issue National Pollutant Discharge Elimination System permits for both chemical pesticide applications that leave a residue or excess in water and all biological pesticide applications that are made in or over, including near, waters of the United States.
This regulation was initially adopted by the State Water Control Board on February 4, 2011, with an effective date of April 10, 2011, and published in the Virginia Register on February 28, 2011. The effective date was suspended on April 4, 2011. The State Water Control Board amended the regulation to revise the effective and expiration dates of the general permit and readopted the regulation on April 14, 2011.
At its meeting on April 14, 2011, the board (i) amended and readopted the VPDES General Permit for Discharges Resulting from the Application of Pesticides to Surface Waters (9VAC25-800) to change the effective date to October 31, 2011, and the expiration date to December 31, 2013; (ii) affirmed that it will receive, consider, and respond to petitions by any person at any time with respect to reconsideration or revision of this regulation, as provided by the Administrative Process Act; (iii) directed the Director of the Department of Environmental Quality to suspend the effective date of the general permit regulation should the 6th Circuit Court of Appeals further delay implementation of its decision; and (iv) directed the director to withdraw the general permit regulation if congressional action repeals or negates authority for the rule.
CHAPTER 800
VIRGINIA POLLUTANT DISCHARGE ELIMINATION SYSTEM (VPDES) GENERAL PERMIT FOR DISCHARGES RESULTING FROM THE APPLICATION OF PESTICIDES TO SURFACE WATERS
9VAC25-800-10. Definitions.
The words and terms used in this chapter shall have the same meanings as given in the State Water Control Law (§ 62.1-44.2 et seq. of the Code of Virginia) and the VPDES Permit Regulation (9VAC25-31), unless the context clearly indicates otherwise, except that for the purposes of this chapter:
"Action threshold" means the point at which pest populations or environmental conditions can no longer be tolerated necessitating that pest control action be taken based on economic, human health, aesthetic, or other effects. Sighting a single pest does not always mean control is needed. Action thresholds help determine both the need for control actions and the proper timing of such actions. Action thresholds are site specific and part of integrated pest management decisions.
"Active ingredient" means any substance (or group of structurally similar substances if specified by the federal Environmental Protection Agency (EPA) that will prevent, destroy, repel, or mitigate any pest, or that functions as a plant regulator, desiccant, or defoliant within the meaning of § 2 (a) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) (7 USC § 136 et seq.). Active ingredient also means a pesticidal substance that is intended to be produced and used in a living plant, or in the produce thereof, and the genetic material necessary for the production of such a pesticidal substance.
"Adverse incident" means an incident that the operator observes upon inspection or of which otherwise becomes aware, in which there is evidence that:
1. A person or nontarget organism has likely been exposed to a pesticide residue; and
2. The person or nontarget organism suffered a toxic or adverse effect.
The phrase "toxic or adverse effects" includes effects that occur within surface waters on nontarget plants, fish, or wildlife that are unusual or unexpected as a result of exposure to a pesticide residue and may include any of the following:
1. Distressed or dead juvenile and small fishes;
2. Washed up or floating fish;
3. Fish swimming abnormally or erratically;
4. Fish lying lethargically at water surface or in shallow water;
5. Fish that are listless or nonresponsive to disturbance;
6. Stunting, wilting, or desiccation of nontarget submerged or emergent aquatic plants; and
7. Other dead or visibly distressed nontarget aquatic or semi-aquatic organisms (amphibians, turtles, invertebrates, etc.).
The phrase "toxic or adverse effects" also includes any adverse effects to humans (e.g., skin rashes), domesticated animals or wildlife (e.g., vomiting, lethargy) that occur either directly or indirectly from a discharge to surface waters that are temporally and spatially related to exposure to a pesticide residue.
"Best management practices" or "BMPs" means, for purposes of this chapter, schedules of activities, prohibitions of practices, maintenance procedures, preventative practices (pre-emergent applications) and other management practices to prevent or reduce the pollution of surface waters. BMPs also include treatment requirements, operating procedures, and practices to control site runoff, spillage, or leaks.
"Biological control" means organisms that can be introduced to sites, such as herbivores, predators, parasites, and hyperparasites.
"Biological pesticides" or "biopesticides" include microbial pesticides, biochemical pesticides, and plant-incorporated protectants (PIP).
1. "Microbial pesticide" means a microbial agent intended for preventing, destroying, repelling, or mitigating any pest, or intended for use as a plant regulator, defoliant, or desiccant, that:
a. Is a eucaryotic microorganism, including but not limited to protozoa, algae, and fungi;
b. Is a procaryotic microorganism, including but not limited to Eubacteria and Archaebacteria; or
c. Is a parasitically replicating microscopic element, including but not limited to viruses.
2. "Biochemical pesticide" means a pesticide that:
a. Is a naturally occurring substance or structurally similar and functionally identical to a naturally occurring substance;
b. Has a history of exposure to humans and the environment demonstrating minimal toxicity, or in the case of a synthetically derived biochemical pesticide, is equivalent to a naturally occurring substance that has such a history; and
c. Has a nontoxic mode of action to the target pest(s).
3. "Plant-incorporated protectant" means a pesticidal substance that is intended to be produced and used in a living plant, or in the produce thereof, and the genetic material necessary for production of such a pesticidal substance. It also includes any inert ingredient contained in the plant or produce thereof.
"Chemical pesticides" means all pesticides not otherwise classified as biological pesticides.
"Control measure" means any best management practice (BMP) or other method used to meet the effluent limitations in this permit. Control measures must comply with label directions and relevant legal requirements. Additionally, control measures could include other actions, including nonchemical tactics (e.g., cultural methods), that a prudent operator would implement to reduce or eliminate discharges resulting from pesticide application to surface waters to comply with the effluent limitations in this permit.
"Cultural methods" means manipulation of the habitat to increase pest mortality by making the habitat less suitable to the pest.
"Declared pest emergency situation" means an event defined by a public declaration by a federal agency, state, or local government of a pest problem determined to require control through application of a pesticide beginning less than 10 days after identification of the need for pest control. This public declaration may be based on:
1. Significant risk to human health;
2. Significant economic loss; or
3. Significant risk to:
a. Endangered species;
b. Threatened species;
c. Beneficial organisms; or
d. The environment.
"DEQ" or "department" means the Virginia Department of Environmental Quality.
"Discharge of a pollutant" means, for purposes of this chapter, any addition of any "pollutant" or combination of pollutants to surface waters from any point source, or any addition of any pollutant or combination of pollutants to the water of the contiguous zone or the ocean from any point source.
"FIFRA" means the Federal Insecticide, Fungicide and Rodenticide Act (7 USC § 136 et seq.) as amended.
"Impaired water" or "water quality impaired water" or "water quality limited segment" means any stream segment where the water quality does not or will not meet applicable water quality standards, even after the application of technology-based effluent limitations required by §§ 301(b) and 306 of the Clean Water Act (CWA) (33 USC § 1251 et seq. as of 1987). Impaired waters include both impaired waters with approved or established TMDLs, and impaired waters for which a TMDL has not yet been approved or established.
"Inert ingredient" means any substance (or group of structurally similar substances if designated by EPA), other than an active ingredient, that is intentionally included in a pesticide product. Inert ingredient also means any substance, such as a selectable marker, other than the active ingredient, where the substance is used to confirm or ensure the presence of the active ingredient, and includes the genetic material necessary for the production of the substance, provided that genetic material is intentionally introduced into a living plant in addition to the active ingredient.
"Integrated pest management" or "IPM" means an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices. IPM uses current, comprehensive information on the life cycles of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment.
"Label" means the written, printed, or graphic matter on, or attached to, the pesticide or device, or the immediate container thereof, and the outside container or wrapper of the retail package, if any, of the pesticide or device.
"Labeling" means all labels and other written, printed, or graphic matter:
1. Upon the pesticide or device or any of its containers or wrappers;
2. Accompanying the pesticide or device at any time; or

To which reference is made on the label or in literature accompanying the pesticide or device, except when accurate, nonmisleading reference is made to current official publications of the agricultural experiment station, the Virginia Polytechnic Institute and State University, the Virginia Department of Agriculture and Consumer Services, the State Board of Health, or similar federal institutions or other official agencies of the Commonwealth or other states when such states are authorized by law to conduct research in the field of pesticides.
"Mechanical/physical methods" means mechanical tools or physical alterations of the environment, for pest prevention or removal.
"Minimize" means to reduce or eliminate pesticide discharges to surface waters through the use of control measures to the extent technologically available and economically practicable and achievable.
"Nontarget organisms" means any organisms that are not the target of the pesticide.
"Operator" means, for purposes of this chapter, any person involved in the application of a pesticide that results in a discharge to state waters that meets either or both of the following two criteria:
1. The person has control over the financing for or the decision to perform pesticide applications that result in discharges, including the ability to modify those decisions; or
2. The person has day-to-day control of or performs activities that are necessary to ensure compliance with the permit (e.g., they are authorized to direct workers to carry out activities required by the permit or perform such activities themselves).
"Person" means, for purposes of this chapter, an individual; a corporation; a partnership; an association; a local, state, or federal governmental body; a municipal corporation; or any other legal entity.
"Pest" means any deleterious organism that is:
1. Any vertebrate animal other than man;
2. Any invertebrate animal excluding any internal parasite of living man or other living animals;
3. Any plant growing where not wanted, and any plant part such as a root; or

Any organism classified as endangered, threatened, or otherwise protected under federal or state laws shall not be deemed a pest for the purposes of this chapter.
"Pest management area" means the area of land, including any water, for which pest management activities covered by this permit are conducted.
"Pesticide" means:
1. Any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any insects, rodents, fungi, bacteria, weeds, or other forms of plant or animal life or viruses, except viruses on or in living man or other animals, which the Commissioner of Agriculture and Consumer Services shall declare to be a pest;
2. Any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant; and
3. Any substance which is intended to become an active ingredient thereof.
Pesticides that are used or applied shall only be those that are approved and registered for use by the Virginia Department of Agriculture and Consumer Services.
"Pesticide product" means a pesticide in the particular form (including active and inert ingredients, packaging, and labeling) in which the pesticide is, or is intended to be, distributed or sold. The term includes any physical apparatus used to deliver or apply the pesticide if distributed or sold with the pesticide.
"Pesticide research and development" means activities undertaken on a systematic basis to gain new knowledge (research) or the application of research findings or other scientific knowledge for the creation of new or significantly improved products or processes (experimental development). These types of activities are generally categorized under 5417 under the 2007 North American Industry Classification System (NAICS).
"Pesticide residue" includes that portion of a pesticide application that has been discharged from a point source to surface waters and no longer provides pesticidal benefits. It also includes any degradates of the pesticide.
"Point source" means, for purposes of this chapter, any discernible, confined, and discrete conveyance including, but not limited to, any pipe, ditch, channel, tunnel, conduit, or container from which pollutants are or may be discharged. This includes biological pesticides or pesticide residuals coming from a container or nozzle of a pesticide application device. This term does not include return flows from irrigated agriculture or agricultural storm water run-off.
"Pollutant" means, for purposes of this chapter, biological pesticides and any pesticide residue resulting from use of a chemical pesticide.
"Surface waters" means:
1. All waters that are currently used, were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters that are subject to the ebb and flow of the tide;
2. All interstate waters, including interstate wetlands;
3. All other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds the use, degradation, or destruction of which would affect or could affect interstate or foreign commerce including any such waters:
a. That are or could be used by interstate or foreign travelers for recreational or other purposes;
b. From which fish or shellfish are or could be taken and sold in interstate or foreign commerce; or
c. That are used or could be used for industrial purposes by industries in interstate commerce.
4. All impoundments of waters otherwise defined as surface waters under this definition;
5. Tributaries of waters identified in subdivisions 1 through 4 of this definition;
6. The territorial sea; and
7. Wetlands adjacent to waters, other than waters that are themselves wetlands, identified in subdivisions 1 through 6 of this definition.
Surface waters do not include waste treatment systems, including treatment ponds or lagoons designed to meet the requirements of the Clean Water Act (CWA) and the law. Surface waters do not include prior converted cropland. Notwithstanding the determination of an area's status as prior converted cropland by any other agency, for the purposes of the CWA, the final authority regarding the CWA jurisdiction remains with the EPA.
"Target pest" means the organism toward which pest control measures are being directed.
"Total maximum daily load" or "TMDL" means a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL includes wasteload allocations (WLAs) for point source discharges, and load allocations (LAs) for nonpoint sources or natural background or both, and must include a margin of safety (MOS) and account for seasonal variations.
"Treatment area" means the area of land including any waters, or the linear distance along water's edge, to which pesticides are being applied. Multiple treatment areas may be located within a single pest management area.
Treatment area includes the entire area, whether over land or water, where the pesticide application is intended to provide pesticidal benefits. In some instances, the treatment area will be larger than the area where pesticides are actually applied. For example, the treatment area for a stationary drip treatment into a canal should be calculated by multiplying the width of the canal by the length over which the pesticide is intended to control weeds. The treatment area for a lake or marine area is the water surface area where the application is intended to provide pesticidal benefits.
Treatment area calculations for pesticide applications that occur at water's edge, where the discharge of pesticides directly to waters is unavoidable, are determined by the linear distance over which pesticides are applied. For example, treating both sides of a five-mile-long river, stream, or ditch is equal to 10 miles of treatment area. Treating five miles of shoreline or coast would equal a five-mile treatment area.
"VDACS" means the Virginia Department of Agriculture and Consumer Services. VDACS administers the provisions of Virginia's pesticide statute, Chapter 39 (§ 3.2-3900 et seq.) of Title 3.2 of the Code of Virginia, as well as the regulations promulgated by the Virginia Pesticide Control Board. VDACS also has delegated authority to enforce the provisions of FIFRA. As such, VDACS is the primary agency for the regulatory oversight of pesticides in the Commonwealth.
"Wetlands" means those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.
9VAC25-800-20. Purpose; delegation of authority; effective date of permit.
A. This general permit regulation governs discharges resulting from the application of pesticides to surface waters.
B. The Director of the Department of Environmental Quality, or his designee, may perform any act of the board provided under this chapter, except as limited by § 62.1-44.14 of the Code of Virginia.
C. This general VPDES permit will become effective on [ April 10, 2011 October 31, 2011 ], and expire on [ June 30, 2013 December 31, 2013 ].
9VAC25-800-30. Authorization to discharge.
A. Any operator that meets the eligibility requirements in subsection B of this section is hereby authorized for his discharges resulting from the application of pesticides to surface waters of the Commonwealth of Virginia.
The definition of operator in 9VAC25-800-10 provides that more than one person may be responsible for the same discharge resulting from pesticide application. Any operator authorized to discharge under this general permit is responsible for compliance with the terms of this permit for discharges resulting from the application of pesticides.
B. Eligibility. This permit is available to operators who discharge to surface waters from the application of (i) biological pesticides, or (ii) chemical pesticides that leave a residue (hereinafter collectively "pesticides"), when the pesticide application is for one of the following pesticide use patterns:
1. Mosquito and other flying insect pest control - to control public health/nuisance and other flying insect pests that develop or are present during a portion of their life cycle in or above standing or flowing water. Public health/nuisance and other flying insect pests in this use category include, but are not limited to, mosquitoes and black flies.
2. Aquatic weed and Weed, algae, and pathogen control - to control invasive or other aquatic (emergent, floating or submerged) nuisance weeds and, algae, and pathogens in surface waters. Aquatic nuisance weeds include, but are not limited to, cattails, hydrilla, and watermeal.
3. Aquatic animal Animal pest control - to control aquatic invasive or other aquatic animal pests in surface waters. Aquatic animal pests in this use category include, but are not limited to, fish (e.g., snakehead) and zebra mussels.
4. Forest canopy pest control - aerial application of a pesticide over a to the forest canopy to control the population of a pest species (e.g., insect or pathogen) where to target the pests effectively a portion of the pesticide unavoidably will be applied over and deposited to surface water.
C. Operators applying pesticides are required to maintain a pesticide discharge management plan (PDMP) if they exceed the annual treatment area thresholds in Table 1 of this subsection:
Table 1. Annual Treatment Area Thresholds |
Pesticide Use | Annual Threshold |
Mosquitoes and Other Flying Insect Pests | 640 6400 acres of treatment area |
Aquatic Weed and Algae Weed, Algae, and Pathogen Control: | |
- In Water | 20 80 acres of treatment area1 |
- At Water's Edge | 20 linear miles of treatment area at water’s edge2 |
Aquatic Animal Pest Control: | |
- In Water | 20 80 acres of treatment area1 |
- At Water's Edge | 20 linear miles of treatment area at water’s edge2 |
Forest Canopy Pest Control | 640 6400 acres of treatment area |
1Calculations include the area of the applications made to: (i) surface waters and (ii) conveyances with a hydrologic surface connection to surface waters at the time of pesticide application. For calculating annual treatment area totals, count each pesticide application activity as a separate activity. For example, applying pesticides twice a year to a 10 acre site is counted as 20 acres of treatment area. |
2Calculation 2Calculations include the linear extent of the application made along the water's edge adjacent to: (i) surface waters and (ii) conveyances with a hydrologic surface connection to surface waters at the time of pesticide application. For calculating annual treatment totals, count each pesticide application activity and each side of a linear water body as a separate activity or area only once. For example, treating both sides of a 10-mile ditch twice a year is equal to 20 10 miles of water treatment area. |
D. An operator's discharge resulting from the application of pesticides is not authorized under this permit in the event of any of the following:
1. The operator is required to obtain an individual VPDES permit in accordance with 9VAC25-31-170 B 3 of the VPDES Permit Regulation.
2. The discharge would violate the antidegradation policy stated in 9VAC25-260-30 of the Virginia Water Quality Standards. Discharges resulting from the application of pesticides are temporary and allowable in exceptional waters (see 9VAC25-260-30 A 3 (b) (3)).
3. The operator is proposing a discharge from a pesticide application to surface waters that have been identified as impaired by that pesticide or its degradates. Impaired waters include both impaired waters with board-adopted, EPA-approved or EPA-imposed TMDLs, and impaired waters for which a TMDL has not yet been approved, established, or imposed.
If the proposed discharge would not be eligible for coverage under this permit because the surface water is listed as impaired for that specific pesticide, but the applicant has evidence that shows the water is no longer impaired, the applicant may submit this information to the board and request that coverage be allowed under this permit.
E. Discharge authorization date. Operators are not required to submit a registration statement and are authorized to discharge under this permit immediately upon the permit's effective date of [ April 10, 2011 October 31, 2011 ].
F. Compliance with this general permit constitutes compliance with the Clean Water Act, the State Water Control Law, and applicable regulations under either, with the exceptions stated in 9VAC25-31-60 of the VPDES Permit Regulation. Approval for coverage under this general VPDES permit does not relieve any operator of the responsibility to comply with any other applicable federal, state, or local statute, ordinance, or regulation. For example, this permit does not negate the requirements under FIFRA and its implementing regulations to use registered pesticides consistent with the product's labeling.
G. Continuation of permit coverage.
1. This general permit shall expire on [ June 30, 2013 December 31, 2013 ], except that the conditions of the expired pesticides general permit will continue in force for an operator until coverage is granted under a reissued pesticides general permit if the board, through no fault of the operator, does not reissue a pesticides general permit on or before the expiration date of the expiring general permit.
2. General permit coverages continued under this section remain fully effective and enforceable.
3. When the operator that was covered under the expiring or expired pesticides general permit is not in compliance with the conditions of that permit, the board may choose to do any or all of the following:
a. Initiate enforcement action based upon the pesticides general permit that has been continued;
b. Issue a notice of intent to deny coverage under a reissued pesticides general permit. If the general permit coverage is denied, the operator would then be required to cease the activities authorized by the continued general permit or be subject to enforcement action for operating without a permit;
c. Issue an individual permit with appropriate conditions; or
