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:

a. Hazardous Waste Management program under RCRA (42 USC § 6921);

b. UIC program under SDWA (42 USC § 300h);

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;

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).

(5) Oil and grease.

(6) Chemical oxygen demand (COD) (if noncontact cooling water is or will be discharged).

(7) Total organic carbon (TOC) (if noncontact cooling water is or will be discharged).

(8) Ammonia (as N).

(9) Discharge flow.

(10) pH.

(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.

I. Application requirements for new and existing concentrated animal feeding operations and aquatic animal production facilities. New and existing concentrated animal feeding operations and concentrated aquatic animal production facilities shall provide the following information to the department, using the application form provided by the department:

J. Application requirements for new and existing POTWs and treatment works treating domestic sewage. Unless otherwise indicated, all POTWs and other dischargers designated by the board must provide to the department, at a minimum, the information in this subsection using an application form provided by the department. 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:

a. Name, mailing address, and location of the facility for which the application is submitted;

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:

y =	x
	1 - r

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:

rc =	rm 8760 - z
	8760

where:

r_m = POTW's consistent removal rate for that pollutant as established under subsections A 1 and B 2 of this section

r_c = 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.
