Summary:

The Environmental Protection Agency published the National Pollutant Discharge Elimination System (NPDES) Electronic Reporting Rule in the Federal Register, 80 FR 64063 (October 22, 2015). This rule provides requirements for the electronic reporting and sharing of NPDES program information. The rule requires the use of electronic reporting instead of paper-based reporting in order to (i) save time and limited resources; (ii) increase data accuracy and improve compliance; and (iii) support better protection of waters. The goal is to improve the ability of authorized programs, such as Virginia's Virginia Pollutant Discharge Elimination System Program, to target the most serious water quality and compliance problems while also helping to shift limited resources to more pertinent tasks by reducing time and resources necessary for the paper-based reporting activities. The final exempt regulatory action amends 9VAC25-31 and 9VAC25-870 in order to incorporate the federal electronic reporting rule.

9VAC25-31-25. Applicability of incorporated references based on the dates that they became effective.

Except as noted, when a regulation of the United States U.S. Environmental Protection Agency set forth in Title 40 of the Code of Federal Regulations is referenced and incorporated herein in this chapter that regulation shall be as it exists and has been published in the July 1, 2013 July 1, 2016, update.

9VAC25-31-110. Signatories to permit applications and reports.

A. All permit applications shall be signed as follows:

1. For a corporation: by a responsible corporate officer. For the purpose of this section, a responsible corporate officer means: (i) a president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy-making or decision-making functions for the corporation, or (ii) the manager of one or more manufacturing, production, or operating facilities, provided the manager is authorized to make management decisions that govern the operation of the regulated facility, including having the explicit or implicit duty of making major capital investment recommendations, and initiating and directing other comprehensive measures to assure long-term environmental compliance with environmental laws and regulations; the manager can ensure that the necessary systems are established or actions taken to gather complete and accurate information for permit application requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures;

2. For a partnership or sole proprietorship: by a general partner or the proprietor, respectively; or

3. For a municipality, state, federal, or other public agency: by either a principal executive officer or ranking elected official. For purposes of this section, a principal executive officer of a federal agency includes: (i) the chief executive officer of the agency, or (ii) a senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency.

B. All reports required by permits, and other information requested by the board shall be signed by a person described in subsection A of this section, or by a duly authorized representative of that person. A person is a duly authorized representative only if:

1. The authorization is made in writing by a person described in subsection A of this section;

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

3. The written authorization is submitted to the department.

C. If an authorization under subsection B of this section is no longer accurate because a different individual or position has responsibility for the overall operation of the facility, a new authorization satisfying the requirements of subsection B of this section must be submitted to the department prior to or together with any reports, or information to be signed by an authorized representative.

D. Any person signing a document under subsection A or B of this section shall make the following certification:

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

E. Electronic reporting. If documents described in subsection A or B of this section are submitted electronically by or on behalf of the VPDES-regulated facility, any person providing the electronic signature for such documents shall meet all relevant requirements of this section and shall ensure that all of the relevant requirements of Part XI (9VAC25-31-950 et seq.) of this chapter and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D).

9VAC25-31-120. Storm water discharges.

A. Permit requirements.

1. Prior to October 1, 1994, discharges composed entirely of storm water shall not be required to obtain a VPDES permit except:

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

b. A discharge associated with industrial activity; or

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

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

3. In addition to meeting the requirements of subsection B of this section, an operator of a storm water discharge associated with industrial activity which discharges through a large or medium municipal separate storm sewer system shall submit, to the operator of the municipal separate storm sewer system receiving the discharge no later than May 15, 1991, or 180 days prior to commencing such discharge: the name of the facility; a contact person and phone number; the location of the discharge; a description, including Standard Industrial Classification, which best reflects the principal products or services provided by each facility; and any existing VPDES permit number.

4. For storm water discharges associated with industrial activity from point sources which discharge through a nonmunicipal or nonpublicly owned separate storm sewer system, the board, in its discretion, may issue: a single VPDES permit, with each discharger a co-permittee to a permit issued to the operator of the portion of the system that discharges into surface waters; or, individual permits to each discharger of storm water associated with industrial activity through the nonmunicipal conveyance system.

a. All storm water discharges associated with industrial activity that discharge through a storm water discharge system that is not a municipal separate storm sewer must be covered by an individual permit, or a permit issued to the operator of the portion of the system that discharges to surface waters, with each discharger to the nonmunicipal conveyance a co-permittee to that permit.

b. Where there is more than one operator of a single system of such conveyances, all operators of storm water discharges associated with industrial activity must submit applications.

c. Any permit covering more than one operator shall identify the effluent limitations, or other permit conditions, if any, that apply to each operator.

5. Conveyances that discharge storm water run-off combined with municipal sewage are point sources that must obtain VPDES permits in accordance with the procedures of 9VAC25-31-100 and are not subject to the provisions of this section.

6. Whether a discharge from a municipal separate storm sewer is or is not subject to VPDES regulation shall have no bearing on whether the owner or operator of the discharge is eligible for funding under Title II, Title III or Title VI of the CWA.

7. a. On and after October 1, 1994, for discharges composed entirely of storm water, that are not required by subdivision 1 of this subsection to obtain a permit, operators shall be required to obtain a VPDES permit only if:

(1) The board or the EPA regional administrator determines that storm water controls are needed for the discharge based on wasteload allocations that are part of "total maximum daily loads" (TMDLs) that address the pollutant(s) of concern; or

(2) The board or the EPA regional administrator determines that the discharge, or category of discharges within a geographic area, contributes to a violation of a water quality standard or is a significant contributor of pollutants to surface waters.

b. Operators of nonmunicipal sources designated pursuant to subdivisions 7 a (1) and (2) of this subsection shall seek coverage under a VPDES permit in accordance with subdivision B 1 of this section.

c. Operators of storm water discharges designated pursuant to subdivisions 7 a (1) and (2) of this subsection shall apply to the board for a permit within 180 days of receipt of notice, unless permission for a later date is granted by the board.

B. Application requirements for storm water discharges associated with industrial activity.

1. Dischargers of storm water associated with industrial activity are required to apply for an individual permit or seek coverage under a promulgated storm water general permit. Facilities that are required to obtain an individual permit, or any discharge of storm water which the board is evaluating for designation under subdivision A 1 c of this section, shall submit a VPDES application in accordance with the requirements of 9VAC25-31-100 as modified and supplemented by the provisions of this subsection.

a. Except as provided in subdivisions 1 b and c of this subsection, the operator of a storm water discharge associated with industrial activity subject to this section shall provide:

(f) The date and duration (in hours) of the storm event or events sampled, rainfall measurements or estimates of the storm event (in inches) which generated the sampled run-off and the duration between the storm event sampled and the end of the previous measurable (greater than 0.1 inch rainfall) storm event (in hours);

(6) Operators of a discharge which is composed entirely of storm water are exempt from the requirements of 9VAC25-31-100 G 2, G 3, G 4, G 5, G 7 c, G 7 d, G 7 e, and G 7 h; and

(7) Operators of new sources or new discharges which are composed in part or entirely of storm water must include estimates for the pollutants or parameters listed in subdivision 1 a (5) of this subsection instead of actual sampling data, along with the source of each estimate. Operators of new sources or new discharges composed in part or entirely of storm water must provide quantitative data for the parameters listed in subdivision 1 a (5) of this subsection within two years after commencement of discharge, unless such data has already been reported under the monitoring requirements of the VPDES permit for the discharge. Operators of a new source or new discharge which is composed entirely of storm water are exempt from the requirements of 9VAC25-31-100 K 3 b, K 3 c, and K 5.

b. The operator of an existing or new discharge composed entirely of storm water from an oil or gas exploration, production, processing, or treatment operation, or transmission facility is not required to submit a permit application in accordance with subdivision 1 a of this subsection, unless the facility:

(2) Has had a discharge of storm water resulting in the discharge of a reportable quantity for which notification is or was required pursuant to 40 CFR 110.6 at any time since November 16, 1987; or

(3) Contributes to a violation of a water quality standard.

c. The operator of an existing or new discharge composed entirely of storm water from a mining operation is not required to submit a permit application unless the discharge has come into contact with any overburden, raw material, intermediate products, finished product, byproduct or waste products located on the site of such operations.

d. Applicants shall provide such other information the board may reasonably require to determine whether to issue a permit.

2. No application for a VPDES permit authorizing direct or indirect discharge of stormwater runoff from a new municipal solid waste landfill into a local watershed protection district established and designated as such by city ordinance prior to January 1, 2006, shall be considered complete unless it contains certification from the local governing body of the city in which the discharge is to take place, that the discharge is consistent with the city's ordinance establishing and designating the local watershed protection district. This requirement shall apply to applications for new or modified individual VPDES permits and for new or modified coverage under general VPDES permits. This requirement does not apply to any municipal solid waste landfill in operation on or before January 1, 2006.

C. Application deadlines. Any operator of a point source required to obtain a permit under this section that does not have an effective VPDES permit authorizing discharges from its storm water outfalls shall submit an application in accordance with the following deadlines:

1. Individual applications.

a. Except as provided in subdivision 1 b of this subsection, for any storm water discharge associated with industrial activity as defined in this chapter which is not authorized by a storm water general permit, a permit application made pursuant to subsection B of this section shall be submitted to the department by October 1, 1992;

b. For any storm water discharge associated with industrial activity from a facility that is owned or operated by a municipality with a population of less than 100,000 that is not authorized by a general or individual permit, other than an airport, powerplant, or uncontrolled sanitary landfill, permit applications must be submitted to the department by March 10, 2003;

2. A permit application shall be submitted to the department within 180 days of notice, unless permission for a later date is granted by the board, for:

a. A storm water discharge which either the board or the regional administrator, determines that the discharge contributes to a violation of a water quality standard or is a significant contributor of pollutants to surface waters; or

b. A storm water discharge subject to subdivision B 1 d of this section;

3. Facilities with existing VPDES permits for storm water discharges associated with industrial activity shall maintain existing permits. Facilities with permits for storm water discharges associated with industrial activity which expire on or after May 18, 1992, shall submit a new application in accordance with the requirements of 9VAC25-31-100 and 9VAC25-31-120 B (Form 1, Form 2F, and other applicable forms) 180 days before the expiration of such permits.

D. Petitions.

1. Any person may petition the board to require a VPDES permit for a discharge which is composed entirely of storm water which contributes to a violation of a water quality standard or is a significant contributor of pollutants to surface waters.

2. The board shall make a final determination on any petition received under this section within 90 days after receiving the petition.

E. Conditional exclusion for no exposure of industrial activities and materials to storm water. Discharges composed entirely of storm water are not storm water discharges associated with industrial activity if there is no exposure of industrial materials and activities to rain, snow, snowmelt or run-off and the discharger satisfies the conditions in subdivisions 1 through 4 of this subsection. No exposure means that all industrial materials and activities are protected by a storm resistant shelter to prevent exposure to rain, snow, snowmelt, and run-off. Industrial materials or activities include, but are not limited to, material handling equipment or activities, industrial machinery, raw materials, intermediate products, by-products, final products, or waste products. Material handling activities include the storage, loading and unloading, transportation, or conveyance of any raw material, intermediate product, final product or waste product.

1. To qualify for this exclusion, the operator of the discharge must:

a. Provide a storm resistant shelter to protect industrial materials and activities from exposure to rain, snow, snow melt, and run-off;

b. Complete and sign (according to 9VAC25-31-110) a certification that there are no discharges of storm water contaminated by exposure to industrial materials and activities from the entire facility, except as provided in subdivision 2 of this subsection;

c. Submit the signed certification to the department once every five years. As of the start date in Table 1 of 9VAC25-31-1020, all certifications submitted in compliance with this section shall be submitted electronically by the owner or operator to the department in compliance with this section and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-31-110, and Part XI (9VAC25-31-950 et seq.) of this chapter. Part XI of this chapter is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of this chapter, owners or operators may be required to report electronically if specified by a particular permit;

d. Allow the department to inspect the facility to determine compliance with the no exposure conditions;

e. Allow the department to make any no exposure inspection reports available to the public upon request; and

f. For facilities that discharge through an MS4, upon request, submit a copy of the certification of no exposure to the MS4 operator, as well as allow inspection and public reporting by the MS4 operator.

2. Storm resistant shelter is not required for:

a. Drums, barrels, tanks, and similar containers that are tightly sealed, provided those containers are not deteriorated and do not leak ("sealed" means banded or otherwise secured and without operational taps or valves);

b. Adequately maintained vehicles used in material handling; and

c. Final products, other than products that would be mobilized in storm water discharge (e.g., rock salt).

3. a. This conditional exclusion from the requirement for a VPDES permit is available on a facility-wide basis only, not for individual outfalls. If a facility has some discharges of storm water that would otherwise be no exposure discharges, individual permit requirements should be adjusted accordingly.

b. If circumstances change and industrial materials or activities become exposed to rain, snow, snow melt, or run-off, the conditions for this exclusion no longer apply. In such cases, the discharge becomes subject to enforcement for unpermitted discharge. Any conditionally exempt discharger who anticipates changes in circumstances should apply for and obtain permit authorization prior to the change of circumstances.

c. Notwithstanding the provisions of this subsection, the board retains the authority to require permit authorization (and deny this exclusion) upon making a determination that the discharge causes, has a reasonable potential to cause, or contributes to an instream excursion above an applicable water quality standard, including designated uses.

4. The no exposure certification requires the submission of the following information, at a minimum, to aid the board in determining if the facility qualifies for the no exposure exclusion:

a. The legal name, address and phone number of the discharger.

b. The facility name and address, the county name and the latitude and longitude where the facility is located.

c. Certification that indicates that none of the following materials or activities are, or will be in the foreseeable future, exposed to precipitation:

(1) Using, storing or cleaning industrial machinery or equipment, and areas where residuals from using, storing or cleaning industrial machinery or equipment remain and are exposed to storm water;

(2) Materials or residuals on the ground or in storm water inlets from spills/leaks;

(3) Materials or products from past industrial activity;

(4) Material handling equipment (except adequately maintained vehicles);

(5) Materials or products during loading/unloading or transporting activities;

(6) Materials or products stored outdoors (except final products intended for outside use, e.g., new cars, where exposure to storm water does not result in the discharge of pollutants);

(7) Materials contained in open, deteriorated or leaking storage drums, barrels, tanks, and similar containers;

(8) Materials or products handled/stored on roads or railways owned or maintained by the discharger;

(9) Waste material (except waste in covered, nonleaking containers, e.g., dumpsters);

(10) Application or disposal of process wastewater (unless otherwise permitted); and

(11) Particulate matter or visible deposits of residuals from roof stacks/vents not otherwise regulated, i.e., under an air quality control permit, and evident in the storm water outflow.

d. All no exposure certifications must include the following certification statement and be signed in accordance with the signatory requirements of 9VAC25-31-110: "I certify under penalty of law that I have read and understand the eligibility requirements for claiming a condition of no exposure and obtaining an exclusion from VPDES storm water permitting; and that there are no discharges of storm water contaminated by exposure to industrial activities or materials from the industrial facility identified in this document (except as allowed under 9VAC25-31-120 E 2). I understand that I am obligated to submit a no exposure certification form once every five years to the Department of Environmental Quality and, if requested, to the operator of the local MS4 into which this facility discharges (where applicable). I understand that I must allow the department, or MS4 operator where the discharge is into the local MS4, to perform inspections to confirm the condition of no exposure and to make such inspection reports publicly available upon request. I understand that I must obtain coverage under a VPDES permit prior to any point source discharge of storm water associated with industrial activity from the facility. I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted. Based upon my inquiry of the person or persons who manage the system, or those persons directly involved in gathering the information, the information submitted is to the best of my knowledge and belief true, accurate and complete. I am aware there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations."

9VAC25-31-170. General permits.

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

1. The general permit shall be written to cover one or more categories or subcategories of discharges or sludge use or disposal practices or facilities described in the permit under subdivision 2 b of this subsection, except those covered by individual permits, within a geographic area. The area should correspond to existing geographic or political boundaries, such as:

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

b. Sewer districts or sewer authorities;

c. City, county, or state political boundaries;

d. State highway systems;

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

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

g. Any other appropriate division or combination of boundaries.

2. The general permit may be written to regulate one or more categories or subcategories of discharges or sludge use or disposal practices or facilities, within the area described in subdivision 1 of this subsection, where the sources within a covered subcategory of discharges are either:

a. Storm water point sources; or

b. One or more categories or subcategories of point sources other than storm water point sources, or one or more categories or subcategories of treatment works treating domestic sewage, if the sources or treatment works treating domestic sewage within each category or subcategory all:

(1) Involve the same or substantially similar types of operations;

(2) Discharge the same types of wastes or engage in the same types of sludge use or disposal practices;

(3) Require the same effluent limitations, operating conditions, or standards for sewage sludge use or disposal;

(4) Require the same or similar monitoring; and

(5) In the opinion of the board, are more appropriately controlled under a general permit than under individual permits.

3. Where sources within a specific category of dischargers are subject to water quality-based limits imposed pursuant to 9VAC25-31-220, the sources in that specific category or subcategory shall be subject to the same water quality-based effluent limitations.

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

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

B. Administration.

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

2. Authorization to discharge, or authorization to engage in sludge use and disposal practices.

a. Except as provided in subdivisions 2 e and 2 f of this subsection, dischargers (or treatment works treating domestic sewage) seeking coverage under a general permit shall submit to the department a written notice of intent to be covered by the general permit. A discharger (or treatment works treating domestic sewage) who fails to submit a notice of intent in accordance with the terms of the permit is not authorized to discharge, (or in the case of a sludge disposal permit, to engage in a sludge use or disposal practice), under the terms of the general permit unless the general permit, in accordance with subdivision 2 e of this subsection, contains a provision that a notice of intent is not required or the board notifies a discharger (or treatment works treating domestic sewage) that it is covered by a general permit in accordance with subdivision 2 f of this subsection. A complete and timely notice of intent (NOI) to be covered in accordance with general permit requirements fulfills the requirements for permit applications for the purposes of this chapter. As of the start date in Table 1 of 9VAC25-31-1020, all notices of intent submitted in compliance with this subsection shall be submitted electronically by the discharger (or treatment works treating domestic sewage) to the department in compliance with this subsection and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-31-110, and Part XI (9VAC25-31-950 et seq.) of this chapter. Part XI of this chapter is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of this chapter, dischargers (or treatment works treating domestic sewage) may be required to report electronically if specified by a particular permit.

b. The contents of the notice of intent shall be specified in the general permit and shall require the submission of information necessary for adequate program implementation, including at a minimum, the legal name and address of the owner or operator, the facility name and address, type of facility or discharges, and the receiving stream or streams and other required data elements as identified in Appendix A to 40 CFR Part 127, as adopted by reference in 9VAC25-31-1030. General permits for storm water discharges associated with industrial activity from inactive mining, inactive oil and gas operations, or inactive landfills occurring on federal lands where an operator cannot be identified may contain alternative notice of intent requirements. Notices of intent for coverage under a general permit for concentrated animal feeding operations must include the information specified in 9VAC25-31-100 J 1, including a topographic map. All notices of intent shall be signed in accordance with 9VAC25-31-110.

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

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

e. Discharges other than discharges from publicly owned treatment works, combined sewer overflows, primary industrial facilities, and storm water discharges associated with industrial activity, may, at the discretion of the board, be authorized to discharge under a general permit without submitting a notice of intent where the board finds that a notice of intent requirement would be inappropriate. In making such a finding, the board shall consider: the type of discharge; the expected nature of the discharge; the potential for toxic and conventional pollutants in the discharges; the expected volume of the discharges; other means of identifying discharges covered by the permit; and the estimated number of discharges to be covered by the permit. The board shall provide in the public notice of the general permit the reasons for not requiring a notice of intent.

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

g. A CAFO owner or operator may be authorized to discharge under a general permit only in accordance with the process described in subdivision C 4 of 9VAC25-31-130.

3. Requiring an individual permit.

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

(1) The discharger or treatment works treating domestic sewage is not in compliance with the conditions of the general VPDES permit;

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

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

(4) A water quality management plan containing requirements applicable to such point sources is approved;

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

(6) Standards for sewage sludge use or disposal have been promulgated for the sludge use and disposal practice covered by the general VPDES permit; or

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

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

(b) The size of the discharge;

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

(d) Other relevant factors.

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

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

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

(3) Prior to a case-by-case determination that an individual permit is required for a storm water discharge under this subsection, the board may require the discharger to submit a permit application or other information regarding the discharge under the law and § 308 of the CWA. In requiring such information, the board shall notify the discharger in writing and shall send an application form with the notice. The discharger must apply for a permit under 9VAC25-31-120 A 1 within 60 days of notice or under 9VAC25-31-120 A 7 within 180 days of notice, unless permission for a later date is granted by the board. The question whether the initial designation was proper will remain open for consideration during the public comment period for the draft permit and in any subsequent public hearing.

c. Any owner or operator authorized by a general permit may request to be excluded from the coverage of the general permit by applying for an individual permit. The owner or operator shall submit an application under 9VAC25-31-100 with reasons supporting the request. The request shall be processed under the applicable parts of this chapter. The request shall be granted by issuing of an individual permit if the reasons cited by the owner or operator are adequate to support the request.

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

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

Part III
Permit Conditions

9VAC25-31-190. Conditions applicable to all permits.

The following conditions apply to all VPDES permits. Additional conditions applicable to VPDES permits are in 9VAC25-31-200. All conditions applicable to VPDES permits shall be incorporated into the permits either expressly or by reference. If incorporated by reference, a specific citation to this regulation must be given in the permit.

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

The permittee shall comply with effluent standards or prohibitions established under § 307(a) of the CWA for toxic pollutants and with standards for sewage sludge use or disposal established under § 405(d) of the CWA within the time provided in the chapters that establish these standards or prohibitions or standards for sewage sludge use or disposal, even if the permit has not yet been modified to incorporate the requirement.

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

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

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

E. The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of the permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of the permit.

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

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

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

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

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

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

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

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

J. Monitoring and records.

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

2. Except for records of monitoring information required by the permit related to the permittee's sewage sludge use and disposal activities, which shall be retained for a period of at least five years (or longer as required by Part VI (9VAC25-31-420 et seq.) of this chapter), the permittee shall retain records of all monitoring information, including all calibration and maintenance records and all original strip chart recordings for continuous monitoring instrumentation, copies of all reports required by the permit, and records of all data used to complete the application for the permit, for a period of at least three years from the date of the sample, measurement, report or application. This period of retention shall be extended automatically during the course of any unresolved litigation regarding the regulated activity or regarding control standards applicable to the permittee, or as requested by the board.

3. Records of monitoring information shall include:

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

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

c. The date or dates analyses were performed;

d. The individual or individuals who performed the analyses;

e. The analytical techniques or methods used; and

f. The results of such analyses.

4. Monitoring results must be conducted according to test procedures approved under 40 CFR Part 136 or alternative EPA approved methods; or, in the case of sludge use or disposal, approved under 40 CFR Part 136 unless otherwise specified in Part VI of this chapter, unless other test procedures have been specified in the permit.

K. All applications, reports, or information submitted to the department shall be signed and certified as required by 9VAC25-31-110.

L. Reporting requirements.

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

a. The alteration or addition to a permitted facility may meet one of the criteria for determining whether a facility is a new source in 9VAC25-31-180 A; or

b. The alteration or addition could significantly change the nature or increase the quantity of pollutants discharged. This notification applies to pollutants which are subject neither to effluent limitations in the permit, nor to notification requirements under 9VAC25-31-200 A 1.

c. The alteration or addition results in a significant change in the permittee's sludge use or disposal practices, and such alteration, addition, or change may justify the application of permit conditions that are different from or absent in the existing permit, including notification of additional use or disposal sites not reported during the permit application process or not reported pursuant to an approved land application plan;

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

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

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

a. Monitoring results must be reported on a Discharge Monitoring Report (DMR) or forms provided or specified by the department for reporting results of monitoring of sludge use or disposal practices. As of the start date in Table 1 of 9VAC25-31-1020, all reports and forms submitted in compliance with this subdivision 4 shall be submitted electronically by the permittee to the department in compliance with this subdivision 4 and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-31-110, and Part XI (9VAC25-31-950 et seq.) of this chapter. Part XI of this chapter is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of this chapter, permittees may be required to report electronically if specified by a particular permit.

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

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

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

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

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

b. Breakdown of processing or accessory equipment;

Prior to this date, and independent of Part XI of this chapter, permittees may be required to report electronically if specified by a particular permit.

3. Prohibition of bypass.

a. Bypass is prohibited, and the board may take enforcement action against a permittee for bypass, unless:

(1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;

(2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and

(3) The permittee submitted notices as required under subdivision 2 of this subsection.

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

N. Upset.

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

2. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:

a. An upset occurred and that the permittee can identify the cause or causes of the upset;

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

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

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

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

9VAC25-31-200. Additional conditions applicable to specified categories of VPDES permits.

The following conditions, in addition to those set forth in 9VAC25-31-190, apply to all VPDES permits within the categories specified below:

A. Existing manufacturing, commercial, mining, and silvicultural dischargers. All existing manufacturing, commercial, mining, and silvicultural dischargers must notify the department as soon as they know or have reason to believe:

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

a. One hundred micrograms per liter (100 µg/l);

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

c. Five times the maximum concentration value reported for that pollutant in the permit application; or

d. The level established by the board in accordance with 9VAC25-31-220 F.

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

a. Five hundred micrograms per liter (500 µg/l);

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

c. Ten times the maximum concentration value reported for that pollutant in the permit application; or

d. The level established by the board in accordance with 9VAC25-31-220 F.

B. Publicly and privately owned treatment works. All POTWs and PVOTWs must provide adequate notice to the department of the following:

1. Any new introduction of pollutants into the POTW or PVOTW from an indirect discharger which would be subject to § 301 or 306 of the CWA and the law if it were directly discharging those pollutants; and

2. Any substantial change in the volume or character of pollutants being introduced into that POTW or PVOTW by a source introducing pollutants into the POTW or PVOTW at the time of issuance of the permit.

3. For purposes of this subsection, adequate notice shall include information on (i) the quality and quantity of effluent introduced into the POTW or PVOTW, and (ii) any anticipated impact of the change on the quantity or quality of effluent to be discharged from the POTW or PVOTW.

4. When the monthly average flow influent to a POTW or PVOTW reaches 95% of the design capacity authorized by the VPDES permit for each month of any three-month period, the owner shall within 30 days notify the department in writing and within 90 days submit a plan of action for ensuring continued compliance with the terms of the permit.

a. The plan shall include the necessary steps and a prompt schedule of implementation for controlling any current problem, or any problem which could be reasonably anticipated, resulting from high influent flows.

b. Upon receipt of the owner's plan of action, the board shall notify the owner whether the plan is approved or disapproved. If the plan is disapproved, such notification shall state the reasons and specify the actions necessary to obtain approval of the plan.

c. Failure to timely submit an adequate plan shall be deemed a violation of the permit.

d. Nothing herein shall in any way impair the authority of the board to take enforcement action under § 62.1-44.15, 62.1-44.23, or 62.1-44.32 of the Code of Virginia.

C. Wastewater works operator requirements.

1. The permittee shall employ or contract at least one wastewater works operator who holds a current wastewater license appropriate for the permitted facility. The license shall be issued in accordance with Title 54.1 of the Code of Virginia and the regulations of the Board for Waterworks and Wastewater Works Operators and Onsite Sewage System Professionals Regulations (18VAC160-20). Notwithstanding the foregoing requirement, unless the discharge is determined by the board on a case-by-case basis to be a potential contributor of pollution, no licensed operator is required for wastewater treatment works:

a. That have a design hydraulic capacity equal to or less than 0.04 mgd;

b. That discharge industrial waste or other waste from coal mining operations; or

c. That do not utilize biological or physical/chemical treatment.

2. In making this case-by-case determination, the board shall consider the location of the discharge with respect to state waters, the size of the discharge, the quantity and nature of pollutants reaching state waters and the treatment methods used at the wastewater works.

3. The permittee shall notify the department in writing whenever he is not complying, or has grounds for anticipating he will not comply with the requirements of subdivision 1 of this subsection. The notification shall include a statement of reasons and a prompt schedule for achieving compliance.

D. Lake level contingency plans. Any VPDES permit issued for a surface water impoundment whose primary purpose is to provide cooling water to power generators shall include a lake level contingency plan to allow specific reductions in the flow required to be released when the water level above the dam drops below designated levels due to drought conditions, and such plan shall take into account and minimize any adverse effects of any release reduction requirements on downstream users. This subsection shall not apply to any such facility that addresses releases and flow requirements during drought conditions in a Virginia Water Protection Permit.

E. Concentrated Animal Feeding Operations (CAFOs). The activities of the CAFO shall not contravene the Water Quality Standards, as amended and adopted by the board, or any provision of the State Water Control Law. There shall be no point source discharge of manure, litter or process wastewater to surface waters of the state except in the case of an overflow caused by a storm event greater than the 25-year, 24-hour storm. Agricultural storm water discharges as defined in subdivision C 3 of 9VAC25-31-130 are permitted. Domestic sewage or industrial waste shall not be managed under the Virginia Pollutant Discharge Elimination System General Permit for CAFOs (9VAC25-191). Any permit issued to a CAFO shall include:

1. Requirements to develop, implement and comply with a nutrient management plan. At a minimum, a nutrient management plan shall include best management practices and procedures necessary to implement applicable effluent limitations and standards. Permitted CAFOs must have their nutrient management plans developed and implemented and be in compliance with the nutrient management plan as a requirement of the permit. The nutrient management plan must, to the extent applicable:

a. Ensure adequate storage of manure, litter, and process wastewater, including procedures to ensure proper operation and maintenance of the storage facilities;

b. Ensure proper management of mortalities (i.e., dead animals) to ensure that they are not disposed of in a liquid manure, storm water, or process wastewater storage or treatment system that is not specifically designed to treat animal mortalities;

c. Ensure that clean water is diverted, as appropriate, from the production area;

d. Prevent direct contact of confined animals with surface waters of the state;

e. Ensure that chemicals and other contaminants handled on site are not disposed of in any manure, litter, process wastewater, or stormwater storage or treatment system unless specifically designed to treat such chemicals and other contaminants;

f. Identify appropriate site specific conservation practices to be implemented, including as appropriate buffers or equivalent practices, to control runoff of pollutants to surface waters of the state;

g. Identify protocols for appropriate testing of manure, litter, process wastewater and soil;

h. Establish protocols to land apply manure, litter or process wastewater in accordance with site specific nutrient management practices that ensure appropriate agricultural utilization of the nutrients in the manure, litter or process wastewater; and

i. Identify specific records that will be maintained to document the implementation and management of the minimum elements described above.

2. Recordkeeping requirements. The permittee must create, maintain for five years, and make available to the director upon request the following records:

a. All applicable records identified pursuant to subdivision 1 i of this subsection;

b. In addition, all CAFOs subject to EPA Effluent Guidelines for Feedlots (40 CFR Part 412) must comply with recordkeeping requirements as specified in 40 CFR 412.37(b) and (c) and 40 CFR 412.47(b) and (c);

A copy of the CAFO's site-specific nutrient management plan must be maintained on site and made available to the director upon request.

3. Requirements relating to transfer of manure or process wastewater to other persons. Prior to transferring manure, litter or process wastewater to other persons, large CAFOs must provide the recipient of the manure, litter or process wastewater with the most current nutrient analysis. The analysis provided must be consistent with the requirements of EPA Effluent Guidelines for Feedlots (40 CFR Part 412). Large CAFOs must retain for five years records of the date, recipient name and address and approximate amount of manure, litter or process wastewater transferred to another person.

4. Annual reporting requirements for CAFOs. The permittee must submit an annual report to the director. As of the start date in Table 1 of 9VAC25-31-1020, all annual reports submitted in compliance with this subsection shall be submitted electronically by the permittee to the department in compliance with this subsection and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-31-110, and Part XI (9VAC25-31-950 et seq.) of this chapter. Part XI of this chapter is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of this chapter, the permittee may be required to report electronically if specified by a particular permit. The annual report must include:

a. The number and type of animals, whether in open confinement or housed under roof (beef cattle, broilers, layers, swine weighing 55 pounds or more, swine weighing less than 55 pounds, mature dairy cows, dairy heifers, veal calves, sheep and lambs, horses, ducks, turkeys, other);

b. Estimated amount of total manure, litter and process wastewater generated by the CAFO in the previous 12 months (tons/gallons);

c. Estimated amount of total manure, litter and process wastewater transferred to other persons by the CAFO in the previous 12 months (tons/gallons);

d. Total number of acres for land application covered by the nutrient management plan developed in accordance with subdivision 1 of this subsection;

e. Total number of acres under control of the CAFO that were used for land application of manure, litter and process wastewater in the previous 12 months;

f. Summary of all manure, litter and process wastewater discharges from the production area that occurred in the previous 12 months including for each discharge the date of discovery, duration of discharge, time and approximate volume;

g. A statement indicating whether the current version of the CAFO's nutrient management plan was developed or approved by a certified nutrient management planner; and

h. The actual crop(s) planted and actual yield(s) for each field, the actual nitrogen and phosphorus content of the manure, litter, and process wastewater, the results of calculations conducted in accordance with subdivisions 5 a (2) and 5 b (4) of this subsection, and the amount of manure, litter, and process wastewater applied to each field during the previous 12 months; and, for any CAFO that implements a nutrient management plan that addresses rates of application in accordance with subdivision 5 b of this subsection, the results of any soil testing for nitrogen and phosphorus taken during the preceding 12 months, the data used in calculations conducted in accordance with subdivision 5 b (4) of this subsection, and the amount of any supplemental fertilizer applied during the previous 12 months.

5. Terms of the nutrient management plan. Any permit issued to a CAFO shall require compliance with the terms of the CAFO's site-specific nutrient management plan. The terms of the nutrient management plan are the information, protocols, best management practices, and other conditions in the nutrient management plan determined by the board to be necessary to meet the requirements of subdivision 1 of this subsection. The terms of the nutrient management plan, with respect to protocols for land application of manure, litter, or process wastewater required by subdivision 4 h of this subsection and, as applicable, 40 CFR 412.4(c), shall include the fields available for land application; field-specific rates of application properly developed, as specified in subdivisions 5 a and b of this subsection, to ensure appropriate agricultural utilization of the nutrients in the manure, litter, or process wastewater; and any timing limitations identified in the nutrient management plan concerning land application on the fields available for land application. The terms shall address rates of application using one of the following two approaches, unless the board specifies that only one of these approaches may be used:

a. Linear approach. An approach that expresses rates of application as pounds of nitrogen and phosphorus, according to the following specifications:

(1) The terms include maximum application rates from manure, litter, and process wastewater for each year of permit coverage, for each crop identified in the nutrient management plan, in chemical forms determined to be acceptable to the board, in pounds per acre, per year, for each field to be used for land application, and certain factors necessary to determine such rates. At a minimum, the factors that are terms shall include: the outcome of the field-specific assessment of the potential for nitrogen and phosphorus transport from each field; the crops to be planted in each field or any other uses of a field such as pasture or fallow fields; the realistic yield goal for each crop or use identified for each field; the nitrogen and phosphorus recommendations from sources specified by the board for each crop or use identified for each field; credits for all nitrogen in the field that will be plant available; consideration of multi-year phosphorus application; and accounting for all other additions of plant available nitrogen and phosphorus to the field. In addition, the terms include the form and source of manure, litter, and process wastewater to be land-applied; the timing and method of land application; and the methodology by which the nutrient management plan accounts for the amount of nitrogen and phosphorus in the manure, litter, and process wastewater to be applied.

(2) Large CAFOs that use this approach shall calculate the maximum amount of manure, litter, and process wastewater to be land applied at least once each year using the results of the most recent representative manure, litter, and process wastewater tests for nitrogen and phosphorus taken within 12 months of the date of land application; or

b. Narrative rate approach. An approach that expresses rates of application as a narrative rate of application that results in the amount, in tons or gallons, of manure, litter, and process wastewater to be land applied, according to the following specifications:

(1) The terms include maximum amounts of nitrogen and phosphorus derived from all sources of nutrients, for each crop identified in the nutrient management plan, in chemical forms determined to be acceptable to the board, in pounds per acre, for each field, and certain factors necessary to determine such amounts. At a minimum, the factors that are terms shall include: the outcome of the field-specific assessment of the potential for nitrogen and phosphorus transport from each field; the crops to be planted in each field or any other uses such as pasture or fallow fields (including alternative crops identified in accordance with subdivision 5 b (2) of this subsection); the realistic yield goal for each crop or use identified for each field; and the nitrogen and phosphorus recommendations from sources specified by the board for each crop or use identified for each field. In addition, the terms include the methodology by which the nutrient management plan accounts for the following factors when calculating the amounts of manure, litter, and process wastewater to be land applied: results of soil tests conducted in accordance with protocols identified in the nutrient management plan, as required by subdivision 1 g of this subsection; credits for all nitrogen in the field that will be plant available; the amount of nitrogen and phosphorus in the manure, litter, and process wastewater to be applied; consideration of multi-year phosphorus application; accounting for all other additions of plant available nitrogen and phosphorus to the field; the form and source of manure, litter, and process wastewater; the timing and method of land application; and volatilization of nitrogen and mineralization of organic nitrogen.

(2) The terms of the nutrient management plan include alternative crops identified in the CAFO's nutrient management plan that are not in the planned crop rotation. Where a CAFO includes alternative crops in its nutrient management plan, the crops shall be listed by field, in addition to the crops identified in the planned crop rotation for that field, and the nutrient management plan shall include realistic crop yield goals and the nitrogen and phosphorus recommendations from sources specified by the board for each crop. Maximum amounts of nitrogen and phosphorus from all sources of nutrients and the amounts of manure, litter, and process wastewater to be applied shall be determined in accordance with the methodology described in subdivision 5 b (1) of this subsection.

(3) For CAFOs using this approach, the following projections shall be included in the nutrient management plan submitted to the board, but are not terms of the nutrient management plan: the CAFO's planned crop rotations for each field for the period of permit coverage; the projected amount of manure, litter, or process wastewater to be applied; projected credits for all nitrogen in the field that will be plant available; consideration of multi-year phosphorus application; accounting for all other additions of plant available nitrogen and phosphorus to the field; and the predicted form, source, and method of application of manure, litter, and process wastewater for each crop. Timing of application for each field, insofar as it concerns the calculation of rates of application, is not a term of the nutrient management plan.

(4) CAFOs that use this approach shall calculate maximum amounts of manure, litter, and process wastewater to be land applied at least once each year using the methodology required in subdivision 5 b (1) of this subsection before land applying manure, litter, and process wastewater and shall rely on the following data:

(a) A field-specific determination of soil levels of nitrogen and phosphorus, including, for nitrogen, a concurrent determination of nitrogen that will be plant available consistent with the methodology required by subdivision 5 b (1) of this subsection, and for phosphorus, the results of the most recent soil test conducted in accordance with soil testing requirements approved by the board; and

(b) The results of most recent representative manure, litter, and process wastewater tests for nitrogen and phosphorus taken within 12 months of the date of land application, in order to determine the amount of nitrogen and phosphorus in the manure, litter, and process wastewater to be applied.

9VAC25-31-210. Establishing permit conditions.

A. In addition to conditions required in all permits, the board shall establish conditions, as required on a case-by-case basis, to provide for and assure compliance with all applicable requirements of the law, the CWA and regulations. These shall include conditions under 9VAC25-31-240 (duration of permits), 9VAC25-31-250 (schedules of compliance) and, 9VAC25-31-220 (monitoring), electronic reporting requirements of 40 CFR Part 3 and Part XI (9VAC25-31-950 et seq.) of this chapter.

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

2. New or reissued permits, and to the extent allowed under Part V of this chapter modified or revoked and reissued permits, shall incorporate each of the applicable requirements referenced in 9VAC25-31-220 and 9VAC25-31-230.

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

9VAC25-31-220. Establishing limitations, standards, and other permit conditions.

In addition to the conditions established under 9VAC25-31-210 A, each VPDES permit shall include conditions meeting the following requirements when applicable.

A. 1. Technology-based effluent limitations and standards based on effluent limitations and standards promulgated under § 301 of the CWA, on new source performance standards promulgated under § 306 of CWA, on case-by-case effluent limitations determined under § 402(a)(1) of CWA, or a combination of the three. For new sources or new dischargers, these technology-based limitations and standards are subject to the provisions of 9VAC25-31-180 B (protection period).

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

B. Other effluent limitations and standards.

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

2. Standards for sewage sludge use or disposal under § 405(d) of the CWA and Part VI (9VAC25-31-420 et seq.) of this chapter unless those standards have been included in a permit issued under the appropriate provisions of Subtitle C of the Solid Waste Disposal Act (42 USC § 6901 et seq.), Part C of Safe Drinking Water Act (42 USC § 300f et seq.), the Marine Protection, Research, and Sanctuaries Act of 1972 (33 USC § 1401 et seq.), or the Clean Air Act (42 USC § 4701 et seq.), or in another permit issued by the Department of Environmental Quality or any other appropriate state agency under another permit program approved by the administrator. When there are no applicable standards for sewage sludge use or disposal, the permit may include requirements developed on a case-by-case basis to protect public health and the environment from any adverse effects which may occur from toxic pollutants in sewage sludge. If any applicable standard for sewage sludge use or disposal is promulgated under § 405(d) of the CWA and that standard is more stringent than any limitation on the pollutant or practice in the permit, the board may initiate proceedings under this chapter to modify or revoke and reissue the permit to conform to the standard for sewage sludge use or disposal.

3. Requirements applicable to cooling water intake structures at new facilities under § 316 (b) of the CWA, in accordance with 9VAC25-31-165.

C. Reopener clause. For any permit issued to a treatment works treating domestic sewage (including sludge-only facilities), the board shall include a reopener clause to incorporate any applicable standard for sewage sludge use or disposal promulgated under § 405(d) of the CWA. The board may promptly modify or revoke and reissue any permit containing the reopener clause required by this subdivision if the standard for sewage sludge use or disposal is more stringent than any requirements for sludge use or disposal in the permit, or controls a pollutant or practice not limited in the permit.

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

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

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

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

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

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

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

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

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

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

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

(b) The fact sheet required by 9VAC25-31-280 sets forth the basis for the limit, including a finding that compliance with the effluent limit on the indicator parameter will result in controls on the pollutant of concern which are sufficient to attain and maintain applicable water quality standards;

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

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

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

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

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

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

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

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

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

6. Ensure consistency with the requirements of a Water Quality Management plan approved by EPA under § 208(b) of the CWA;

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

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

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

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

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

a. Limitations on those pollutants; or

b. Limitations on other pollutants which, in the judgment of the board, will provide treatment of the pollutants under subdivision 1 of this subsection to the levels required by the law and 40 CFR Part 125, Subpart A.

F. A notification level which exceeds the notification level of 9VAC25-31-200 A 1 a, b, or c, upon a petition from the permittee or on the board's initiative. This new notification level may not exceed the level which can be achieved by the technology-based treatment requirements appropriate to the permittee.

G. Twenty-four-hour reporting. Pollutants for which the permittee must report violations of maximum daily discharge limitations under 9VAC25-31-190 L 7 b (3) (24-hour reporting) shall be listed in the permit. This list shall include any toxic pollutant or hazardous substance, or any pollutant specifically identified as the method to control a toxic pollutant or hazardous substance.

H. Durations for permits, as set forth in 9VAC25-31-240.

I. Monitoring requirements. The following monitoring requirements:

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

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

3. Applicable reporting requirements based upon the impact of the regulated activity and as specified in 9VAC25-31-190 and in, subdivisions 5 through 8 of this subsection, and Part XI (9VAC25-31-950 et seq.) of this chapter. Reporting shall be no less frequent than specified in the above regulation;

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

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

b. The volume of effluent discharged from each outfall;

c. Other measurements as appropriate including pollutants in internal waste streams; pollutants in intake water for net limitations; frequency, rate of discharge, etc., for noncontinuous discharges; pollutants subject to notification requirements; and pollutants in sewage sludge or other monitoring as specified in Part VI (9VAC25-31-420 et seq.) of this chapter; or as determined to be necessary on a case-by-case basis pursuant to the law and § 405(d)(4) of the CWA; and

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

5. Except as provided in subdivisions 7 and 8 of this subsection, requirements to report monitoring results shall be established on a case-by-case basis with a frequency dependent on the nature and effect of the discharge, but in no case less that once a year. For sewage sludge use or disposal practices, requirements to monitor and report results shall be established on a case-by-case basis with a frequency dependent on the nature and effect of the sewage sludge use or disposal practice; minimally this shall be as specified in Part VI (9VAC25-31-420 et seq.) of this chapter (where applicable), but in no case less than once a year. All results shall be electronically reported in compliance with 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-31-110, and Part XI (9VAC25-31-950 et seq.) of this chapter;

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

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

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

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

c. Such report and certification be signed in accordance with 9VAC25-31-110; and

d. Permits for storm water discharges associated with industrial activity from inactive mining operations may, where annual inspections are impracticable, require certification once every three years by a Registered Professional Engineer that the facility is in compliance with the permit, or alternative requirements; and

8. Permits which do not require the submittal of monitoring result reports at least annually shall require that the permittee report all instances of noncompliance not reported under 9VAC25-31-190 L 1, 4, 5, 6, and 7 at least annually.

J. Pretreatment program for POTWs. Requirements for POTWs to:

1. Identify, in terms of character and volume of pollutants, any significant indirect dischargers into the POTW subject to pretreatment standards under § 307(b) of the CWA and Part VII (9VAC25-31-730 et seq.) of this chapter;

2. Submit a local program when required by and in accordance with Part VII of this chapter to assure compliance with pretreatment standards to the extent applicable under § 307(b) of the CWA. The local program shall be incorporated into the permit as described in Part VII of this chapter. The program shall require all indirect dischargers to the POTW to comply with the reporting requirements of Part VII of this chapter;

3. Provide a written technical evaluation of the need to revise local limits under Part VII of this chapter following permit issuance or reissuance; and

4. For POTWs which are sludge-only facilities, a requirement to develop a pretreatment program under Part VII of this chapter when the board determines that a pretreatment program is necessary to assure compliance with Part VI of this chapter.

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

1. Authorized under § 304(e) of the CWA for the control of toxic pollutants and hazardous substances from ancillary industrial activities;

2. Authorized under § 402(p) of the CWA for the control of storm water discharges;

3. Numeric effluent limitations are infeasible; or

4. The practices are reasonably necessary to achieve effluent limitations and standards or to carry out the purposes and intent of the law and the CWA.

L. Reissued permits.

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

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

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

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

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

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

d. The permittee has received a permit modification under the law and §§ 301(c), 301(g), 301(h), 301(i), 301(k), 301(n), or 316(a) of the CWA; or

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

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

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

M. For a privately owned treatment works, any conditions expressly applicable to any user, as a limited co-permittee, that may be necessary in the permit issued to the treatment works to ensure compliance with applicable requirements under this part. Alternatively, the board may issue separate permits to the treatment works and to its users, or may require a separate permit application from any user. The board's decision to issue a permit with no conditions applicable to any user, to impose conditions on one or more users, to issue separate permits, or to require separate applications, and the basis for that decision, shall be stated in the fact sheet for the draft permit for the treatment works.

N. Any conditions imposed in grants made by the board to POTWs under §§ 201 and 204 of the CWA which are reasonably necessary for the achievement of effluent limitations under § 301 of the CWA and the law.

O. Requirements governing the disposal of sewage sludge from publicly owned treatment works or any other treatment works treating domestic sewage for any use regulated by Part VI of this chapter.

P. When a permit is issued to a facility that may operate at certain times as a means of transportation over water, a condition that the discharge shall comply with any applicable regulations promulgated by the secretary of the department in which the Coast Guard is operating, that establish specifications for safe transportation, handling, carriage, and storage of pollutants.

Q. Navigation. Any conditions that the Secretary of the Army considers necessary to ensure that navigation and anchorage will not be substantially impaired in accordance with 9VAC25-31-330.

9VAC25-31-400. Minor modifications of permits.

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

A. Correct typographical errors;

B. Require more frequent monitoring or reporting by the permittee;

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

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

E. 1. Change the construction schedule for a discharger which is a new source. No such change shall affect a discharger's obligation to have all pollution control equipment installed and in operation prior to discharge.

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

F. Incorporate conditions of an approved POTW pretreatment program (or a modification thereto that has been approved in accordance with the procedures in this chapter) as enforceable conditions of the POTW's permits.

G. Incorporate changes to the terms of a CAFO's nutrient management plan that have been revised in accordance with the requirements of subdivision C 5 of 9VAC25-31-130.

H. Require electronic reporting requirements (to replace paper reporting requirements) including those specified in 40 CFR Part 3 and Part XI (9VAC25-31-950 et seq.) of this chapter.

9VAC25-31-410. Termination of permits.

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

1. The permittee has violated any regulation or order of the board, any provision of the law, or any order of a court, where such violation results in a release of harmful substances into the environment or poses a substantial threat of release of harmful substances into the environment or presents a hazard to human health or the violation is representative of a pattern of serious or repeated violations which in the opinion of the board, demonstrates the permittee's disregard for or inability to comply with applicable laws, regulations or requirements;

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

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

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

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

6. There exists a material change in the basis on which the permit was issued that requires either a temporary or a permanent reduction or elimination of any discharge controlled by the permit necessary to protect human health or the environment.

B. The board shall follow the applicable procedures in this chapter in terminating any VPDES permit under this section, except that if the entire discharge is permanently terminated by elimination of the flow or by connection to a POTW or a PVOTW (but not by land application or disposal into a well), the board may terminate the permit by notice to the permittee. Termination by notice shall be effective 30 days after notice is sent, unless the permittee objects within that time. If the permittee objects during that period, the board shall follow the applicable procedures for termination under 9VAC25-31-370 D. Expedited permit termination procedures are not available to permittees that are subject to pending state or federal enforcement actions including citizen suits brought under state or federal law. If requesting expedited permit termination procedures, a permittee must certify that it is not subject to any pending state or federal enforcement actions including citizen suits brought under state or federal law.

C. Permittees that wish to terminate their permit must submit a notice of termination (NOT) to the department. If requesting expedited permit termination procedures, a permittee must certify in the NOT that it is not subject to any pending state or federal enforcement actions including citizen suits brought under state or federal law. As of the start date in Table 1 of 9VAC25-31-1020, all NOTs submitted in compliance with this subsection shall be submitted electronically by the permittee to the department in compliance with this subsection and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-31-110, and Part XI (9VAC25-31-950 et seq.) of this chapter. Part XI of this chapter is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of this chapter, the permittee may be required to report electronically if specified by a particular permit.

9VAC25-31-840. Reporting requirements for POTWs and industrial users.

A. (Reserved.)

B. Reporting requirements for industrial users upon effective date of categorical pretreatment standard baseline report. Within 180 days after the effective date of a categorical pretreatment standard, or 180 days after the final administrative decision made upon a category determination submission under 9VAC25-31-780 A 4, whichever is later, existing industrial users subject to such categorical pretreatment standards and currently discharging to or scheduled to discharge to a POTW shall be required to submit to the control authority a report which contains the information listed in subdivisions 1 through 7 of this subsection. At least 90 days prior to commencement of discharge, new sources and sources that become industrial users subsequent to the promulgation of an applicable categorical standard shall be required to submit to the control authority a report which contains the information listed in subdivisions 1 through 5 of this subsection. New sources shall also be required to include in this report information on the method of pretreatment the source intends to use to meet applicable pretreatment standards. New sources shall give estimates of the information requested in subdivisions 4 and 5 of this subsection.

1. Identifying information. The user shall submit the name and address of the facility including the name of the operator and owners.

2. Permits. The user shall submit a list of any environmental control permits held by or for the facility.

3. Description of operations. The user shall submit a brief description of the nature, average rate of production, and standard industrial classification of the operation or operations carried out by such industrial user. This description should include a schematic process diagram which indicates points of discharge to the POTW from the regulated processes.

4. Flow measurement. The user shall submit information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from each of the following:

a. Regulated process streams; and

b. Other streams as necessary to allow use of the combined wastestream formula of 9VAC25-31-780 E. (See subdivision 5 d of this subsection.)

The control authority may allow for verifiable estimates of these flows where justified by cost or feasibility considerations.

5. Measurement of pollutants.

a. The user shall identify the pretreatment standards applicable to each regulated process;

b. In addition, the user shall submit the results of sampling and analysis identifying the nature and concentration (or mass, where required by the standard or control authority) of regulated pollutants in the discharge from each regulated process. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations. In cases where the standard requires compliance with a Best Management Practice or pollution prevention alternative, the user shall submit documentation as required by the control authority or the applicable standards to determine compliance with the standard;

c. The user shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this subsection;

d. Samples shall be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated process if no pretreatment exists. If other wastewaters are mixed with the regulated wastewater prior to pretreatment, the user shall measure the flows and concentrations necessary to allow use of the combined wastestream formula of 9VAC25-31-780 E in order to evaluate compliance with the pretreatment standards. Where an alternate concentration or mass limit has been calculated in accordance with 9VAC25-31-780 E, this adjusted limit along with supporting data shall be submitted to the control authority;

e. Sampling and analysis shall be performed in accordance with the techniques prescribed in 40 CFR Part 136 and amendments thereto. Where 40 CFR Part 136 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 by 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;

f. The control authority may allow the submission of a baseline report which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures; and

g. The baseline report shall indicate the time, date and place of sampling, and methods of analysis, and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to the POTW

6. Certification. A statement, reviewed by an authorized representative of the industrial user (as defined in subsection M of this section) and certified to by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance (O and M) or additional pretreatment, or both, are required for the industrial user to meet the pretreatment standards and requirements.

7. Compliance schedule. If additional pretreatment or O and M, or both, will be required to meet the pretreatment standards, the shortest schedule by which the industrial user will provide such additional pretreatment or O and M, or both. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard.

a. Where the industrial user's categorical pretreatment standard has been modified by a removal allowance (9VAC25-31-790), the combined wastestream formula (9VAC25-31-780 E), or a fundamentally different factors variance (9VAC25-31-850), or any combination of them, at the time the user submits the report required by this subsection, the information required by subdivisions 6 and 7 of this subsection shall pertain to the modified limits.

b. If the categorical pretreatment standard is modified by a removal allowance (9VAC25-31-790), the combined wastestream formula (9VAC25-31-780 E), or a fundamentally different factors variance (9VAC25-31-850), or any combination of them, after the user submits the report required by this subsection, any necessary amendments to the information requested by subdivisions 6 and 7 of this subsection shall be submitted by the user to the control authority within 60 days after the modified limit is approved.

C. Compliance schedule for meeting categorical pretreatment standards. The following conditions shall apply to the schedule required by subdivision B 7 of this section:

1. The schedule shall contain increments of progress in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the industrial user to meet the applicable categorical pretreatment standards (e.g., hiring an engineer, completing preliminary plans, completing final plans, executing contract for major components, commencing construction, completing construction, etc.);

2. No increment referred to in subdivision 1 of this subsection shall exceed nine months; and

3. Not later than 14 days following each date in the schedule and the final date for compliance, the industrial user shall submit a progress report to the control authority including, at a minimum, whether or not it complied with the increment of progress to be met on such date and, if not, the date on which it expects to comply with this increment of progress, the reason for delay, and the steps being taken by the industrial user to return the construction to the schedule established. In no event shall more than nine months elapse between such progress reports to the control authority.

D. Report on compliance with categorical pretreatment standard deadline. Within 90 days following the date for final compliance with applicable categorical pretreatment standards or in the case of a new source following commencement of the introduction of wastewater into the POTW, any industrial user subject to pretreatment standards and requirements shall submit to the control authority a report containing the information described in subdivisions B 4 through B 6 of this section. For industrial users subject to equivalent mass or concentration limits established by the control authority in accordance with the procedures in 9VAC25-31-780 C, this report shall contain a reasonable measure of the user's long-term production rate. For all other industrial users subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the user's actual production during the appropriate sampling period.

E. Periodic reports on continued compliance.

1. Any industrial user subject to a categorical pretreatment standard, after the compliance date of such pretreatment standard, or, in the case of a new source, after commencement of the discharge into the POTW, shall submit to the control authority during the months of June and December, unless required more frequently in the pretreatment standard or by the control authority or the director, a report indicating the nature and concentration of pollutants in the effluent which are limited by such categorical pretreatment standards. In addition, this report shall include a record of measured or estimated average and maximum daily flows for the reporting period for the discharge reported in subdivision B 4 of this section except that the control authority may require more detailed reporting of flows. In cases where the pretreatment standard requires compliance with a Best Management Practice (or pollution prevention alternative), the user shall submit documentation required by the control authority or the pretreatment standard necessary to determine the compliance status of the user. At the discretion of the control authority and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the control authority may agree to alter the months during which the above reports are to be submitted. For industrial users for which the department is the control authority, as of the start date in Table 1 of 9VAC25-31-1020, all reports submitted in compliance with this subsection shall be submitted electronically by the industrial user to the department in compliance with this subsection and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-31-110, and Part XI (9VAC25-31-950 et seq.) of this chapter. Part XI of this chapter is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of this chapter, the industrial users for which the department is the control authority may be required to report electronically if specified by a particular control mechanism.

2. The control authority may authorize the industrial user subject to a categorical pretreatment standard to forego sampling of a pollutant regulated by a categorical pretreatment standard if the industrial user has demonstrated through sampling and other technical factors that the pollutant is neither present nor expected to be present in the discharge, or is present only at background levels from intake water and without any increase in the pollutant due to activities of the industrial user. This authorization is subject to the following conditions:

a. The control authority may authorize a waiver where a pollutant is determined to be present solely due to sanitary wastewater discharged from the facility provided that the sanitary wastewater is not regulated by an applicable categorical standard and otherwise includes no process wastewater.

b. The monitoring waiver is valid only for the duration of the effective period of the permit or other equivalent individual control mechanism, but in no case longer than five years. The user must submit a new request for the waiver before the waiver can be granted for each subsequent control mechanism.

c. In making a demonstration that a pollutant is not present, the industrial user must provide data from at least one sampling of the facility's process wastewater prior to any treatment present at the facility that is representative of all wastewater from all processes. The request for a monitoring waiver must be signed in accordance with subsection L of this subsection, and include the certification statement in 9VAC25-31-780 A 2 b. Nondetectable sample results may only be used as a demonstration that a pollutant is not present if the EPA approved method from 40 CFR Part 136 with the lowest minimum detection level for that pollutant was used in the analysis.

d. Any grant of the monitoring waiver by the control authority must be included as a condition in the user's control mechanism. The reasons supporting the waiver and any information submitted by the user in its request for the waiver must be maintained by the control authority for three years after expiration of the waiver.

e. Upon approval of the monitoring waiver and revision of the user's control mechanism by the control authority, the industrial user must certify on each report with the statement below, that there has been no increase in the pollutant in its wastestream due to activities of the industrial user:

"Based on my inquiry of the person or persons directly responsible for managing compliance with the pretreatment standard for 40 CFR [specify applicable national pretreatment standard part(s)], I certify that, to the best of my knowledge and belief, there has been no increase in the level of [list pollutant(s)] in the wastewaters due to the activities at the facility since filing of the last periodic report under 9VAC25-31-840 E 1."

f. In the event that a waived pollutant is found to be present or is expected to be present based on changes that occur in the user's operations, the user must immediately: Comply with the monitoring requirements of subdivision 1 of this subsection or other more frequent monitoring requirements imposed by the control authority, and notify the control authority.

g. This provision does not supersede certification processes and requirements established in categorical pretreatment standards, except as otherwise specified in the categorical pretreatment standard.

3. The control authority may reduce the requirement in the subdivision 1 of this subsection to a requirement to report no less frequently than once a year, unless required more frequently in the pretreatment standard or by the approval authority, where the industrial user meets all of the following conditions:

a. The industrial user's total categorical wastewater flow does not exceed any of the following:

(1) 0.01% of the design dry weather hydraulic capacity of the POTW, or 5,000 gallons per day, whichever is smaller, as measured by a continuous effluent flow monitoring device unless the industrial user discharges in batches;

(2) 0.01% of the design dry weather organic treatment capacity of the POTW; and

(3) 0.01% of the maximum allowable headworks loading for any pollutant regulated by the applicable categorical pretreatment standard for which approved local limits were developed by a POTW in accordance with 9VAC25-31-770 C and D.

b. The industrial user has not been in significant noncompliance, as defined in 9VAC25-31-800 F 2 g, for any time in the past two years;

c. The Industrial User does not have daily flow rates, production levels, or pollutant levels that vary so significantly that decreasing the reporting requirement for this Industrial User would result in data that are not representative of conditions occurring during the reporting period pursuant to subdivision G 3 of this section;

d. The industrial user must notify the control authority immediately of any changes at its facility causing it to no longer meet conditions of subdivision 3 a or b of this subsection. Upon notification, the industrial user must immediately begin complying with the minimum reporting in subdivision 1 of this subsection; and

e. The control authority must retain documentation to support the control authority's determination that a specific industrial user qualifies for reduced reporting requirements under subdivision 3 of this subsection for a period of three years after the expiration of the term of the control mechanism.

4. Where the control authority has imposed mass limitations on industrial users as provided for by 9VAC25-31-780 C, the report required by subdivision 1 of this subsection shall indicate the mass of pollutants regulated by pretreatment standards in the discharge from the industrial user.

5. For industrial users subject to equivalent mass or concentration limits established by the control authority in accordance with the procedures in 9VAC25-31-780 C, the report required by subdivision 1 of this subsection shall contain a reasonable measure of the user's long-term production rate. For all other industrial users subject to categorical pretreatment standards expressed only in terms of allowable pollutant discharge per unit of production (or other measure of operation), the report required by subdivision 1 of this subsection shall include the user's actual average production rate for the reporting period.

F. Notice of potential problems, including slug loading. All categorical and noncategorical industrial users shall notify the POTW immediately of all discharges that could cause problems to the POTW, including any slug loadings, as defined by 9VAC25-31-770 B, by the industrial user.

G. Monitoring and analysis to demonstrate continued compliance with pretreatment standards and requirements.

1. Except in the case of nonsignificant categorical users, the reports required in subsections B, D, E, and H of this section shall contain the results of sampling and analysis of the discharge, including the flow and the nature and concentration, or production and mass where requested by the control authority, of pollutants contained therein which are limited by the applicable pretreatment standards. This sampling and analysis may be performed by the control authority in lieu of the industrial user. Where the POTW performs the required sampling and analysis in lieu of the industrial user, the user will not be required to submit the compliance certification required under subdivision B 6 and subsection D of this section. In addition, where the POTW itself collects all the information required for the report, including flow data, the industrial user will not be required to submit the report.

2. If sampling performed by an industrial user indicates a violation, the user shall notify the control authority within 24 hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the control authority within 30 days after becoming aware of the violation. Where the control authority has performed the sampling and analysis in lieu of the industrial user, the control authority must perform the repeat sampling and analysis unless it notifies the user of the violation and requires the user to perform the repeat analysis. Resampling is not required if:

a. The control authority performs sampling at the industrial user at a frequency of at least once per month; or

b. The control authority performs sampling at the user between the time when the initial sampling was conducted and the time when the user or the control authority receives the results of this sampling.

3. The reports required in subsection E of this section must be based upon data obtained through appropriate sampling and analysis performed during the period covered by the report, which data are representative of conditions occurring during the reporting period. The control authority shall require that frequency of monitoring necessary to assess and assure compliance by industrial users with applicable pretreatment standards and requirements. Grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds. For all other pollutants, 24-hour composite samples must be obtained through flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by the control authority. Where time-proportional composite sampling or grab sampling is authorized by the control authority, the samples must be representative of the discharge and the decision to allow the alternative sampling must be documented in the industrial user file for that facility or facilities. Using protocols (including appropriate preservation) specified in 40 CFR Part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited prior to the analysis as follows: for cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil and grease the samples may be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the control authority, as appropriate.

4. For sampling required in support of baseline monitoring and 90-day compliance reports required in subsections B and D of this section, a minimum of four grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide and volatile organic compounds for facilities for which historical sampling data do not exist; for facilities for which historical sampling data are available, the Control Authority may authorize a lower minimum. For the reports required by subsections E and H of this section, the control authority shall require the number of grab samples necessary to assess and assure compliance by industrial users with applicable pretreatment standards and requirements.

5. All analyses shall be performed in accordance with procedures contained in 40 CFR Part 136 and amendments thereto or with any other test procedures approved by EPA, and shall be reported to the control authority. Sampling shall be performed in accordance with EPA-approved techniques. Where 40 CFR Part 136 does not include sampling or analytical techniques for the pollutants in question, or where EPA determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed using validated analytical methods or any other sampling and analytical procedures, including procedures suggested by the POTW or other parties, approved by EPA.

6. If an industrial user subject to the reporting requirement in subsection E or H of this section monitors any regulated pollutant at the appropriate sampling location more frequently than required by the control authority, using the procedures prescribed in subdivision 5 of this subsection, the results of this monitoring shall be included in the report.

H. Reporting requirements for industrial users not subject to categorical pretreatment standards. The control authority must require appropriate reporting from those industrial users with discharges that are not subject to categorical pretreatment standards. Significant noncategorical industrial users must submit to the control authority at least once every six months (on dates specified by the control authority) a description of the nature, concentration, and flow of the pollutants required to be reported by the control authority. In cases where a local limit requires compliance with a Best Management Practice or pollution prevention alternative, the user must submit documentation required by the control authority to determine the compliance status of the user. These reports must be based on sampling and analysis performed in the period covered by the report, and in accordance with the techniques described in 40 CFR Part 136 and amendments thereto. This sampling and analysis may be performed by the control authority in lieu of the significant noncategorical industrial user. For industrial users for which the department is the control authority, as of the start date in Table 1 of 9VAC25-31-1020, all reports submitted in compliance with this subsection shall be submitted electronically by the industrial user to the department in compliance with this subsection and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-31-110, and Part XI (9VAC25-31-950 et seq.) of this chapter. Part XI of this chapter is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of this chapter, the industrial users for which the department is the control authority may be required to report electronically if specified by a particular control mechanism.

I. Annual POTW reports. POTWs with approved pretreatment programs shall provide the department with a report that briefly describes the POTW's program activities, including activities of all participating agencies if more than one jurisdiction is involved in the local program. The report required by this section shall be submitted no later than one year after approval of the POTW's pretreatment program, and at least annually thereafter, and shall include, at a minimum, the following:

1. An updated list of the POTW's industrial users, including their names and addresses, or a list of deletions and additions keyed to a previously submitted list. The POTW shall provide a brief explanation of each deletion. This list shall identify which industrial users are subject to categorical pretreatment standards and specify which standards are applicable to each industrial user. The list shall indicate which industrial users are subject to local standards that are more stringent than the categorical pretreatment standards. The POTW shall also list the industrial users that are subject only to local requirements. The list must also identify industrial users subject to categorical pretreatment standards that are subject to reduced reporting requirements under subdivision E 3 of this section and identify which industrial users are nonsignificant categorical industrial users.;

2. A summary of the status of industrial user compliance over the reporting period;

3. A summary of compliance and enforcement activities (including inspections) conducted by the POTW during the reporting period;

4. A summary of changes to the POTW's pretreatment program that have not been previously reported to the department; and

5. Any other relevant information requested by the director.;

6. Any additional applicable required data in Appendix A to 40 CFR Part 127 as adopted by reference in 9VAC25-31-1030; and

7. As of the start date in Table 1 of 9VAC25-31-1020, all annual reports submitted in compliance with this subsection shall be submitted electronically by the POTW pretreatment program to the department in compliance with this subsection and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-31-110, and Part XI (9VAC25-31-950 et seq.) of this chapter. Part XI of this chapter is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of this chapter, the department may also require POTW pretreatment programs to electronically submit annual reports under this section if specified by a particular permit.

J. Notification of changed discharge. All industrial users shall promptly notify the control authority (and the POTW if the POTW is not the control authority) in advance of any substantial change in the volume or character of pollutants in their discharge, including the listed or characteristic hazardous wastes for which the industrial user has submitted initial notification under the Code of Virginia and this section.

K. Compliance schedule for POTWs. The following conditions and reporting requirements shall apply to the compliance schedule for development of an approvable POTW pretreatment program required by 9VAC25-31-800:

1. The schedule shall contain increments of progress in the form of dates for the commencement and completion of major events leading to the development and implementation of a POTW pretreatment program (e.g., acquiring required authorities, developing funding mechanisms, acquiring equipment);

2. No increment referred to in subdivision 1 of this subsection shall exceed nine months; and

3. Not later than 14 days following each date in the schedule and the final date for compliance, the POTW shall submit a progress report to the department including, at a minimum, whether or not it complied with the increment of progress to be met on such date and, if not, the date on which it expects to comply with this increment of progress, the reason for delay, and the steps taken by the POTW to return to the schedule established. In no event shall more than nine months elapse between such progress reports to the department.

L. Signatory requirements for industrial user reports. The reports required by subsections B, D, and E of this section shall include the certification statement as set forth in 9VAC25-31-780 A 2 b, and shall be signed as follows:

1. By a responsible corporate officer, if the industrial user submitting the reports required by subsections B, D and E of this section is a corporation. For the purpose of this subdivision, a responsible corporate officer means (i) a president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy-making or decision-making functions for the corporation, or (ii) the manager of one or more manufacturing, production, or operating facilities, provided, the manager is authorized to make management decisions that govern the operation of the regulated facility including having the explicit or implicit duty of making major capital investment recommendations, and initiate and direct other comprehensive measures to assure long-term environmental compliance with environmental laws and regulations; can ensure that the necessary systems are established or actions taken to gather complete and accurate information for control mechanism requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures.

2. By a general partner or proprietor if the industrial user submitting the reports required by subsections B, D and E of this section is a partnership or sole proprietorship, respectively.

3. By a duly authorized representative of the individual designated in subdivision 1 or 2 of this subsection if:

a. The authorization is made in writing by the individual described in subdivision 1 or 2 of this subsection;

b. The authorization specifies either an individual or a position having responsibility for the overall operation of the facility from which the industrial discharge originates, such as the position of plant manager, operator of a well, or well field superintendent, or a position of equivalent responsibility, or having overall responsibility for environmental matters for the company; and

c. The written authorization is submitted to the control authority.

4. If an authorization under subdivision 3 of this subsection is no longer accurate because a different individual or position has responsibility for the overall operation of the facility, or overall responsibility for environmental matters for the company, a new authorization satisfying the requirements of subdivision 3 of this subsection must be submitted to the control authority prior to or together with any reports to be signed by an authorized representative.

M. Signatory requirements for POTW reports. Reports submitted to the department by the POTW in accordance with subsection I of this section must be signed by a principal executive officer, ranking elected official or other duly authorized employee. The duly authorized employee must be an individual or position having responsibility for the overall operation of the facility or the pretreatment program. This authorization must be made in writing by the principal executive officer or ranking elected official, and submitted to the approval authority prior to or together with the report being submitted.

N. Provision governing fraud and false statements. The reports and other documents required to be submitted or maintained under this section shall be subject to:

1. The provisions of 18 USC § 1001 relating to fraud and false statements;

2. The provisions of the law or § 309(c)(4) of the CWA, as amended, governing false statements, representation or certification; and

3. The provisions of § 309(c)(6) of the CWA regarding responsible corporate officers.

O. Recordkeeping requirements.

1. Any industrial user and POTW subject to the reporting requirements established in this section shall maintain records of all information resulting from any monitoring activities required by this section including documentation associated with Best Management Practices. Such records shall include for all samples:

a. The date, exact place, method, and time of sampling and the names of the person or persons taking the samples;

b. The dates analyses were performed;

c. Who performed the analyses;

d. The analytical techniques/methods used; and

e. The results of such analyses.

2. Any industrial user or POTW subject to the reporting requirements established in this section (including documentation associated with Best Management Practices) shall be required to retain for a minimum of three years any records of monitoring activities and results (whether or not such monitoring activities are required by this section) and shall make such records available for inspection and copying by the director and the regional administrator (and POTW in the case of an industrial user). This period of retention shall be extended during the course of any unresolved litigation regarding the industrial user or POTW or when requested by the director or the regional administrator.

3. Any POTW to which reports are submitted by an industrial user pursuant to subsections B, D, E, and H of this section shall retain such reports for a minimum of three years and shall make such reports available for inspection and copying by the director and the regional administrator. This period of retention shall be extended during the course of any unresolved litigation regarding the discharge of pollutants by the industrial user or the operation of the POTW pretreatment program or when requested by the director or the regional administrator.

P. 1. The industrial user shall notify the POTW, the EPA Regional Waste Management Division Director, and state hazardous waste authorities in writing of any discharge into the POTW of a substance, which, if otherwise disposed of, would be a hazardous waste under the Code of Virginia and 40 CFR Part 261. Such notification must include the name of the hazardous waste as set forth in the Code of Virginia and 40 CFR Part 261, the EPA hazardous waste number, and the type of discharge (continuous, batch, or other). If the industrial user discharges more than 100 kilograms of such waste per calendar month to the POTW, the notification shall also contain the following information to the extent such information is known and readily available to the industrial user: An identification of the hazardous constituents contained in the wastes, an estimation of the mass and concentration of such constituents in the wastestream discharged during that calendar month, and an estimation of the mass of constituents in the wastestream expected to be discharged during the following 12 months. All notifications must take place within 180 days of the effective date of this rule. Industrial users who commence discharging after the effective date of this rule shall provide the notification no later than 180 days after the discharge of the listed or characteristic hazardous waste. Any notification under this subsection need be submitted only once for each hazardous waste discharged. However, notifications of changed discharges must be submitted under subsection J of this section. The notification requirement in this section does not apply to pollutants already reported under self-monitoring requirements of subsections B, D, and E of this section.

2. Dischargers are exempt from the requirements of subdivision 1 of this subsection during a calendar month in which they discharge no more than 15 kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e). Discharge of more than 15 kilograms of nonacute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), requires a one-time notification. Subsequent months during which the industrial user discharges more than such quantities of any hazardous waste do not require additional notification.

3. In the case of any new regulations under § 3001 of RCRA (42 USC § 6901 et seq.) identifying additional characteristics of hazardous waste or listing any additional substance as a hazardous waste, the industrial user must notify the POTW, the EPA Regional Waste Management Waste Division Director, and state hazardous waste authorities of the discharge of such substance within 90 days of the effective date of such regulations.

4. In the case of any notification made under this subsection, the industrial user shall certify that it has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical.

Q. Annual certification by nonsignificant categorical industrial users. A facility determined to be a nonsignificant categorical industrial user pursuant to 9VAC25-31-10 must annually submit the following certification statement, signed in accordance with the signatory requirements in subsection L of this section.

9VAC25-870-370. Signatories to state permit applications and reports.

A. All state permit applications shall be signed as follows:

1. For a corporation: by a responsible corporate officer. For the purpose of this section, a responsible corporate officer means: (i) a president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy-making or decision-making functions for the corporation, or (ii) the manager of one or more manufacturing, production, or operating facilities, provided the manager is authorized to make management decisions that govern the operation of the regulated facility, including having the explicit or implicit duty of making major capital investment recommendations, and initiating and directing other comprehensive measures to assure long-term environmental compliance with environmental laws and regulations; the manager can ensure that the necessary systems are established or actions taken to gather complete and accurate information for state permit application requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures;

2. For a partnership or sole proprietorship: by a general partner or the proprietor, respectively; or

3. For a municipality, state, federal, or other public agency: by either a principal executive officer or ranking elected official. For purposes of this section, a principal executive officer of a federal agency includes (i) the chief executive officer of the agency, or (ii) a senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency.

B. All reports required by state permits, and other information requested by the board shall be signed by a person described in subsection A of this section, or by a duly authorized representative of that person. A person is a duly authorized representative only if:

1. The authorization is made in writing by a person described in subsection A of this section;

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

3. The written authorization is submitted to the department.

C. If an authorization under subsection B of this section is no longer accurate because a different individual or position has responsibility for the overall operation of the facility, a new authorization satisfying the requirements of subsection B of this section must be submitted to the department prior to or together with any reports, or information to be signed by an authorized representative.

D. Any person signing a document under subsection A or B of this section shall make the following certification:

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

E. Electronic reporting. If documents described in subsection A or B of this section are submitted electronically by or on behalf of a VPDES-regulated facility, any person providing the electronic signature for such documents shall meet all relevant requirements of this section and shall ensure that all of the relevant requirements of Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D) are met for that submission.

9VAC25-870-400. Small municipal separate storm sewer systems.

A. Objectives of the stormwater regulations for small MS4s.

1. Subsections A through G of this section are written in a "readable regulation" format that includes both rule requirements and guidance. The recommended guidance is distinguished from the regulatory requirements by putting the guidance in a separate subdivision headed by the word "Note."

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

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

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

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

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

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

b. You are designated by the board, including where the designation is pursuant to subdivisions C 3 a and b of this section or is based upon a petition under 9VAC25-870-380 D.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

b. (1) If you are seeking authorization to discharge under an individual state permit and wish to implement a program under subsection D of this section, you must submit an application to the board that includes the information required under 9VAC25-870-360 F and subdivision D 4 of this section, an estimate of square mileage served by your small MS4, and any additional information that the board requests. A storm sewer map that satisfies the requirement of subdivision D 2 c (1) of this section will satisfy the map requirement in 9VAC25-870-360 F 7.

(2) If you are seeking authorization to discharge under an individual state permit and wish to implement a program that is different from the program under subsection D of this section, you will need to comply with the state permit application requirements of 9VAC25-870-380 C. You must submit both parts of the application requirements in 9VAC25-870-380 C 1 and 2 by March 10, 2003. You do not need to submit the information required by 9VAC25-870-380 C 1 b and C 2 regarding your legal authority, unless you intend for the state permit writer to take such information into account when developing your other state permit conditions.

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

c. If your small MS4 is in the same urbanized area as a medium or large MS4 with a state permit and that other MS4 is willing to have you participate in its stormwater program, you and the other MS4 may jointly seek a modification of the other MS4 state permit to include you as a limited state co-permittee. As a limited state co-permittee, you will be responsible for compliance with the state permit's conditions applicable to your jurisdiction. If you choose this option you will need to comply with the state permit application requirements of 9VAC25-870-380, rather than the requirements of subsection D of this section. You do not need to comply with the specific application requirements of 9VAC25-870-380 C 1 c and d and 9VAC25-870-380 C 2 c (discharge characterization). You may satisfy the requirements in 9VAC25-870-380 C 1 e and 2 d (identification of a management program) by referring to the other MS4's stormwater management program.

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

3. If you operate a regulated small MS4:

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

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

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

1. Your MS4 state permit will require at a minimum that you develop, implement, and enforce a stormwater management program designed to reduce the discharge of pollutants from your MS4 to the maximum extent practicable (MEP), to protect water quality, and to satisfy the appropriate water quality requirements of the Clean Water Act, the Virginia Stormwater Management Act, and the State Water Control Law. Your stormwater management program must include the minimum control measures described in subdivision 2 of this subsection unless you apply for a state permit under 9VAC25-870-380 C. For purposes of this section, narrative effluent limitations requiring implementation of best management practices (BMPs) are generally the most appropriate form of effluent limitations when designed to satisfy technology requirements (including reductions of pollutants to the maximum extent practicable) and to protect water quality. Implementation of best management practices consistent with the provisions of the stormwater management program required pursuant to this section and the provisions of the state permit required pursuant to subsection C of this section constitutes compliance with the standard of reducing pollutants to the maximum extent practicable. The board will specify a time period of up to five years from the date of state permit issuance for you to develop and implement your program.

2. Minimum control measures.

a. Public education and outreach on stormwater impacts.

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

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

b. Public involvement/participation.

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

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

c. Illicit discharge detection and elimination.

(1) You must develop, implement and enforce a program to detect and eliminate illicit discharges (as defined in 9VAC25-870-10) into your small MS4.

(2) You must:

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

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

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

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

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

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

d. Construction site stormwater runoff control.

(1) You must develop, implement, and enforce a program to reduce pollutants in any stormwater runoff to your small MS4 from construction activities that result in a land disturbance of greater than or equal to one acre, or equal to or greater than 2,500 square feet in all areas of the jurisdictions designated as subject to the Chesapeake Bay Preservation Area Designation and Management Regulations adopted pursuant to the Chesapeake Bay Preservation Act. Reduction of stormwater discharges from construction activity disturbing less than one acre must be included in your program if that construction activity is part of a larger common plan of development or sale that would disturb one acre or more. If the board waives requirements for stormwater discharges associated with small construction activity in accordance with the definition in 9VAC25-870-10, you are not required to develop, implement, and/or enforce a program to reduce pollutant discharges from such sites.

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

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

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

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

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

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

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

(3) NOTE: Examples of sanctions to ensure compliance include nonmonetary penalties, fines, bonding requirements and/or state permit denials for noncompliance. The board recommends that procedures for site plan review include the review of individual pre-construction site plans to ensure consistency with VESCP requirements. Procedures for site inspections and enforcement of control measures could include steps to identify priority sites for inspection and enforcement based on the nature of the construction activity, topography, and the characteristics of soils and receiving water quality. You are encouraged to provide appropriate educational and training measures for construction site operators. You may wish to require a stormwater pollution prevention plan for construction sites within your jurisdiction that discharge into your system. (See 9VAC25-870-460 L and subdivision E 2 of this section.) The board may recognize that another government entity may be responsible for implementing one or more of the minimum measures on your behalf.

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

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

(2) You must:

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

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

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

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

f. Pollution prevention/good housekeeping for municipal operations.

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

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

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

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

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

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

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

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

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

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

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

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

7. Evaluation and assessment.

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

b. You must keep records required by the state permit for at least three years. You must submit your records to the department only when specifically asked to do so. You must make your records, including a description of your stormwater management program, available to the public at reasonable times during regular business hours (see 9VAC25-870-340 for confidentiality provision). You may assess a reasonable charge for copying. You may require a member of the public to provide advance notice.

c. Unless you are relying on another entity to satisfy your state permit obligations under subdivision E 1 of this section, you must submit annual reports to the department for your first state permit term. For subsequent state permit terms, you must submit reports in years two and four unless the department requires more frequent reports. As of the start date in Table 1 of 9VAC25-31-1020, all reports submitted in compliance with this subsection shall be submitted electronically by the owner, operator, or the duly authorized representative of the small MS4 to the department in compliance with this section and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-870-370, and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation. Part XI of 9VAC25-31 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of 9VAC25-31, the owner, operator, or the duly authorized representative of the small MS4 may be required to report electronically if specified by a particular permit. Your report must include:

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

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

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

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

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

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

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

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

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

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

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

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

State permits are enforceable under the Clean Water Act and the Virginia Stormwater Management Act. Violators may be subject to the enforcement actions and penalties described in Clean Water Act §§ 309(b), (c), and (g) and 505 or under §§ 62.1-44.15:39 through 62.1-44.15:48 of the Code of Virginia. Compliance with a state permit issued pursuant to § 402 of the Clean Water Act is deemed compliance, for purposes of §§ 309 and 505, with §§ 301, 302, 306, 307, and 403, except any standard imposed under § 307 for toxic pollutants injurious to human health. If you are covered as a state co-permittee under an individual permit or under a general permit by means of a joint registration statement, you remain subject to the enforcement actions and penalties for the failure to comply with the terms of the state permit in your jurisdiction except as set forth in subdivision E 2 of this section.

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

EPA intends to conduct an enhanced research effort and compile a comprehensive evaluation of the NPDES MS4 stormwater program. The board will reevaluate the regulations based on data from the EPA NPDES MS4 stormwater program, from research on receiving water impacts from stormwater, and the effectiveness of best management practices (BMPs), as well as other relevant information sources.

9VAC25-870-410. General permits.

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

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

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

b. Sewer districts or sewer authorities;

c. City, county, or state political boundaries;

d. State highway systems;

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

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

g. Any other appropriate division or combination of boundaries.

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

3. Where sources within a specific category of dischargers are subject to water quality-based limits imposed pursuant to 9VAC25-870-460, the sources in that specific category or subcategory shall be subject to the same water quality-based effluent limitations.

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

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

B. Administration.

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

2. Authorization to discharge.

a. Except as provided in subdivisions 2 e and 2 f of this subsection, dischargers seeking coverage under a general permit shall submit to the department a written notice of intent to be covered by the general permit. A discharger who fails to submit a notice of intent in accordance with the terms of the state permit is not authorized to discharge, under the terms of the general permit unless the general permit, in accordance with subdivision 2 e of this subsection, contains a provision that a notice of intent is not required or the board notifies a discharger (or treatment works treating domestic sewage) that it is covered by a general permit in accordance with subdivision 2 f of this subsection. A complete and timely notice of intent (NOI) to be covered in accordance with general permit requirements fulfills the requirements for permit applications for the purposes of this chapter. As of the start date in Table 1 of 9VAC25-31-1020, all notices of intent submitted in compliance with this subdivision shall be submitted electronically by the discharger (or treatment works treating domestic sewage) to the department in compliance with this subdivision and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-870-370, and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation. Part XI of 9VAC25-31 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of 9VAC25-31, dischargers (or treatment works treating domestic sewage) may be required to report electronically if specified by a particular permit.

b. The contents of the notice of intent shall be specified in the general permit and shall require the submission of information necessary for adequate program implementation, including at a minimum, the legal name and address of the owner or operator, the facility name and address, type of facility or discharges, and the receiving stream or streams, and other required data elements as identified in Appendix A to 40 CFR Part 127 as adopted by reference in 9VAC25-31-1030. All notices of intent shall be signed in accordance with 9VAC25-870-370.

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

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

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

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

3. Requiring an individual permit.

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

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

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

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

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

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

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

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

(b) The size of the discharge;

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

(d) Other relevant factors;

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

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

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

(3) Prior to a case-by-case determination that an individual permit is required for a stormwater discharge under this subsection, the board may require the discharger to submit a state permit application or other information regarding the discharge under the Act and § 308 of the CWA. In requiring such information, the board shall notify the discharger in writing and shall send an application form with the notice. The discharger must apply for a state permit under 9VAC25-870-380 A 1 within 60 days of notice or under 9VAC25-870-380 A 8 within 180 days of notice, unless permission for a later date is granted by the board. The question whether the initial designation was proper will remain open for consideration during the public comment period for the draft state permit and in any subsequent public hearing.

c. Any owner or operator authorized by a general permit may request to be excluded from the coverage of the general permit by applying for an individual permit. The owner or operator shall submit an application under 9VAC25-870-360 with reasons supporting the request. The request shall be processed under the applicable parts of this chapter. The request shall be granted by issuing of an individual permit if the reasons cited by the owner or operator are adequate to support the request.

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

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

Part VIII
State Permit Conditions

9VAC25-870-430. Conditions applicable to all state permits.

The following conditions apply to all state permits. Additional conditions applicable to state permits are in 9VAC25-870-440. All conditions applicable to state permits shall be incorporated into the state permits either expressly or by reference. If incorporated by reference, a specific citation to this regulation must be given in the state permit.

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

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

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

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

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

E. The state permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) that are installed or used by the state permittee to achieve compliance with the conditions of the state permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems that are installed by a state permittee only when the operation is necessary to achieve compliance with the conditions of the state permit.

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

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

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

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

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

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

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

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

J. Monitoring and records.

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

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

3. Records of monitoring information shall include:

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

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

c. The date or dates analyses were performed;

d. The individual or individuals who performed the analyses;

e. The analytical techniques or methods used; and

f. The results of such analyses.

4. Monitoring results must be conducted according to test procedures approved under 40 CFR Part 136 or alternative EPA approved methods, unless other test procedures have been specified in the state permit. Analyses performed according to test procedures approved under 40 CFR Part 136 shall be performed by an environmental laboratory certified under regulations adopted by the Department of General Services (1VAC30-45 or 1VAC30-46).

K. All applications, reports, or information submitted to the VSMP authority and department shall be signed and certified as required by 9VAC25-870-370.

L. Reporting requirements.

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

a. The alteration or addition to a permitted facility may meet one of the criteria for determining whether a facility is a new source in 9VAC25-870-420 A; or

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

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

3. State permits are not transferable to any person except in accordance with 9VAC25-870-620.

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

a. Monitoring results must be reported on a Discharge Monitoring Report (DMR) or forms provided or specified by the department. As of the start date in Table 1 of 9VAC25-31-1020, all reports and forms submitted in compliance with this subdivision shall be submitted electronically by the permittee to the department in compliance with this section and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-870-370, and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation. Part XI of 9VAC25-31 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of 9VAC25-31, permittees may be required to report electronically if specified by a particular permit.

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

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

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

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

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

b. Breakdown of processing or accessory equipment;

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

d. Flooding or other acts of nature.

7. Twenty-four hour and five-day reporting.

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

(1) For noncompliance events related to combined sewer overflows, sanitary sewer overflows, or bypass events, these reports must include the data described in subdivision 7 a of this subsection (with the exception of time of discovery), as well as the type of event (i.e., combined sewer overflows, sanitary sewer overflows, or bypass events); type of sewer overflow structure (e.g., manhole, combine sewer overflow outfall); discharge volumes untreated by the treatment works treating domestic sewage; types of human health and environmental impacts of the sewer overflow event; and whether the noncompliance was related to wet weather.

(2) As of the start date in Table 1 of 9VAC25-31-1020, all reports related to combined sewer overflows, sanitary sewer overflows, or bypass events submitted in compliance with this subdivision 7 shall be submitted electronically by the permittee to the department in compliance with this subdivision 7 and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-870-370, and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation. Part XI of 9VAC25-31 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of 9VAC25-31, permittees may be required to electronically submit reports related to combined sewer overflows, sanitary sewer overflows, or bypass events under this subdivision 7 by a particular permit.

(3) The director may also require permittees to electronically submit reports not related to combined sewer overflows, sanitary sewer overflows, or bypass events under this subdivision 7.

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

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

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

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

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

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

a. For noncompliance events related to combined sewer overflows, sanitary sewer overflows, or bypass events, these reports shall contain the information described in subdivision 7 a of this subsection and the applicable required data in Appendix A to 40 CFR Part 127 as adopted by reference in 9VAC25-31-1030.

b. As of the start date in Table 1 of 9VAC25-31-1020, all reports related to combined sewer overflows, sanitary sewer overflows, or bypass events submitted in compliance with this subdivision 8 shall be submitted electronically by the permittee to the department in compliance with this subdivision 8 and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-870-370, and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation. Part XI of 9VAC25-31 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of 9VAC25-31, permittees may be required to electronically submit reports related to combined sewer overflows, sanitary sewer overflows, or bypass events under this section by a particular permit.

c. The director may also require permittees to electronically submit reports not related to combined sewer overflows, sanitary sewer overflows, or bypass events under this section.

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

10. The owner, operator, or the duly authorized representative of an VPDES-regulated entity is required to electronically submit the required information, as specified in Appendix A to 40 CFR Part 127 as adopted by reference in 9VAC25-31-1030, to the department.

M. Bypass.

1. The state permittee may allow any bypass to occur that does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of subdivisions 2 and 3 of this subsection.

2. Notice.

a. Anticipated bypass. If the state permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least 10 days before the date of the bypass. As of the start date in Table 1 of 9VAC25-31-1020, all notices submitted in compliance with this subdivision shall be submitted electronically by the permittee to the department in compliance with this subsection and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-870-370, and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation. Part XI of 9VAC25-31 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of 9VAC25-31, permittees may be required to report electronically if specified by a particular permit.

b. Unanticipated bypass. The state permittee shall submit notice of an unanticipated bypass as required in subdivision L 7 of this section (24-hour notice). As of the start date in Table 1 of 9VAC25-31-1020, all notices submitted in compliance with this subdivision shall be submitted electronically by the permittee to the department in compliance with this subdivision and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-870-370, and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation. Part XI of 9VAC25-31 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of 9VAC25-31, permittees may be required to report electronically if specified by a particular permit.

3. Prohibition of bypass.

a. Bypass is prohibited, and the board may take enforcement action against a state permittee for bypass, unless:

(1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;

(2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventive maintenance; and

(3) The state permittee submitted notices as required under subdivision 2 of this subsection.

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

N. Upset.

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

2. A state permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:

a. An upset occurred and that the state permittee can identify the cause or causes of the upset;

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

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

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

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

9VAC25-870-440. Additional conditions applicable to municipal separate storm sewer state permits.

In addition to those conditions set forth in 9VAC25-870-430, the operator of a large or medium municipal separate storm sewer system or a municipal separate storm sewer that has been designated by the board under 9VAC25-870-380 A 1 e must submit an annual report by a date specified in the state permit for such system. As of the start date in Table 1 of 9VAC25-31-1020, all reports submitted in compliance with this section shall be submitted electronically by the owner, operator, or the duly authorized representative of the MS4 to the department in compliance with this section and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-870-370, and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation. Part XI of 9VAC25-31 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of 9VAC25-31, the owner, operator, or the duly authorized representative of the small MS4 may be required to report electronically if specified by a particular permit. The report shall include:

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

2. Proposed changes to the stormwater management programs that are established as state permit conditions. Such proposed changes shall be consistent with 9VAC25-870-380 C 2 d;

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

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

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

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

7. Identification of water quality improvements or degradation.

9VAC25-870-450. Establishing state permit conditions.

A. In addition to conditions required in all state permits, the board shall establish conditions, as required on a case-by-case basis, to provide for and assure compliance with all applicable requirements of the Stormwater Management Act, the State Water Control Law, the CWA, and attendant regulations. These shall include conditions under 9VAC25-870-480 (duration of state permits), 9VAC25-870-490 (schedules of compliance) and, 9VAC25-870-460 (monitoring), electronic reporting requirements of 40 CFR Part 3, and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation.

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

2. New or reissued state permits, and to the extent allowed under Part X of this chapter modified or revoked and reissued state permits, shall incorporate each of the applicable requirements referenced in 9VAC25-870-460 and 9VAC25-870-470.

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

9VAC25-870-460. Establishing limitations, standards, and other state permit conditions.

In addition to the conditions established under 9VAC25-870-450 A, each state permit shall include conditions meeting the following requirements when applicable.

A. 1. Technology-based effluent limitations and standards based on effluent limitations and standards promulgated under § 301 of the CWA, on new source performance standards promulgated under § 306 of CWA, on case-by-case effluent limitations determined under § 402(a)(1) of CWA, or a combination of the three. For new sources or new dischargers, these technology-based limitations and standards are subject to the provisions of 9VAC25-870-420 B (protection period).

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

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

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

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

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

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

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

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

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

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

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

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

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

(b) The fact sheet required by 9VAC25-870-520 sets forth the basis for the limit, including a finding that compliance with the effluent limit on the indicator parameter will result in controls on the pollutant of concern which are sufficient to attain and maintain applicable water quality standards;

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

a. Limitations on those pollutants; or

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

E. A notification level that exceeds the notification level of 9VAC25-870-440 A 1 a, b, or c, upon a petition from the state permittee or on the board's initiative. This new notification level may not exceed the level which can be achieved by the technology-based treatment requirements appropriate to the state permittee.

F. Twenty-four-hour reporting. Pollutants for which the state permittee must report violations of maximum daily discharge limitations under 9VAC25-870-430 L 7 b (3) (24-hour reporting) shall be listed in the state permit. This list shall include any toxic pollutant or hazardous substance, or any pollutant specifically identified as the method to control a toxic pollutant or hazardous substance.

G. Durations for state permits, as set forth in 9VAC25-870-480.

H. Monitoring requirements.

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

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

3. Applicable reporting requirements based upon the impact of the regulated activity and as specified in 9VAC25-870-430 and in, subdivisions 5 through 8 of this subsection, and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation. Reporting shall be no less frequent than specified in the above regulation;

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

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

b. The volume of effluent discharged from each outfall;

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

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

e. With analyses performed according to test procedures approved under 40 CFR Part 136 being performed by an environmental laboratory certified under regulations adopted by the Department of General Services (1VAC30-45 or 1VAC30-46).

5. Except as provided in subdivisions 7 and 8 of this subsection, requirements to report monitoring results shall be established on a case-by-case basis with a frequency dependent on the nature and effect of the discharge, but in no case less that once a year. All results shall be electronically reported in compliance with 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-870-370, and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation;

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

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

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

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

c. Such report and certification be signed in accordance with 9VAC25-870-370; and

8. State permits which do not require the submittal of monitoring result reports at least annually shall require that the state permittee report all instances of noncompliance not reported under 9VAC25-870-430 L 1, 4, 5, 6, and 7 at least annually.

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

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

2. Numeric effluent limitations are infeasible; or

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

J. Reissued state permits.

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

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

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

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

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

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

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

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

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

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

K. Navigation. Any conditions that the Secretary of the Army considers necessary to ensure that navigation and anchorage will not be substantially impaired in accordance with 9VAC25-870-570.

L. Qualifying state, tribal, or local programs.

1. For stormwater discharges associated with small construction activity identified in 9VAC25-870-10, the board may include state permit conditions that incorporate qualifying state, tribal, or local erosion and sediment control program requirements by reference. Where a qualifying state, tribal, or local program does not include one or more of the elements in this subdivision, then the board must include those elements as conditions in the state permit. A qualifying state, tribal, or local erosion and sediment control program is one that includes:

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

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

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

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

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

9VAC25-870-640. Minor modifications of individual state permits.

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

1. Correct typographical errors;

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

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

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

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

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

6. Require electronic reporting requirements (to replace paper reporting requirements) including those specified in 40 CFR Part 3 and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation.

9VAC25-870-650. Termination of state permits.

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

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

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

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

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

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

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

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

B. The board shall follow the applicable procedures in this chapter in terminating any state permit under this section, except that if the entire discharge is permanently terminated by elimination of the flow or by connection to a POTW or a PVOTW (but not by land application or disposal into a well), the board may terminate the state permit by notice to the state permittee. Termination by notice shall be effective 30 days after notice is sent, unless the state permittee objects within that time. If the state permittee objects during that period, the board shall follow the applicable procedures for termination under 9VAC25-870-610 D. Expedited state permit termination procedures are not available to state permittees that are subject to pending state or federal enforcement actions including citizen suits brought under state or federal law. If requesting expedited state permit termination procedures, a state permittee must certify that it is not subject to any pending state or federal enforcement actions including citizen suits brought under state or federal law.

C. Permittees that wish to terminate their state permit must submit a notice of termination (NOT) to the department. If requesting expedited permit termination procedures, a permittee must certify in the NOT that it is not subject to any pending state or federal enforcement actions including citizen suits brought under state or federal law. As of the start date in Table 1 of 9VAC25-31-1020, all NOTs submitted in compliance with this subsection shall be submitted electronically by the permittee to the department in compliance with this subsection and 40 CFR Part 3 (including, in all cases, 40 CFR Part 3 Subpart D), 9VAC25-870-370, and Part XI (9VAC25-31-950 et seq.) of the Virginia Pollutant Discharge Elimination System (VPDES) Permit Regulation. Part XI of 9VAC25-31 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of Part XI of 9VAC25-31, the permittee may be required to report electronically if specified by a particular permit.
