Summary:

This proposed regulatory action amends and reissues the General Permit for Discharges of Stormwater from Small Municipal Separate Storm Sewer Systems (MS4s). This action to update and reissue the General Permit is authorized under the federal Clean Water Act (33 USC § 1251 et seq.) and the Virginia Stormwater Management Act (§ 10.1-603.2 et seq.) which require that state permits be effective for a fixed term not to exceed five years. The existing five-year General Permit became effective on July 9, 2008.

This proposed regulatory action sets forth guidelines for the permitting of discharges of stormwater runoff from small municipal separate storm sewer systems (small MS4s) in urbanized areas. Small MS4s include systems owned or operated by municipalities, federal facilities, state facilities (including VDOT), and universities. The proposed General Permit establishes standard language for control of small MS4 stormwater discharges through the development, implementation, and enforcement of an MS4 program to reduce the impacts of the stormwater discharges on the receiving streams to the maximum extent practicable. The MS4 Program will require the operator to identify best management practices (BMPs) to control stormwater discharges and measurable goals for each identified BMP for each of the following control measures: (1) public education and outreach on stormwater impacts, (2) public involvement/participation, (3) illicit discharge detection and elimination, (4) construction site stormwater runoff control, (5) post-construction stormwater management in new development and development on prior developed lands, and (6) pollution prevention/good housekeeping for municipal operations. The proposed General Permit requires the operator to evaluate program compliance, the appropriateness of identified BMPs, progress towards achieving the identified measurable goals, and to submit annual reports. The proposed action also requires that the operator address Total Maximum Daily Load (TMDL) Wasteload Allocations, including those associated with the Chesapeake Bay TMDL, assigned to the operator and contains other conditions governing the development, implementation, and reporting requirements of an MS4 Program.

The key changes to this permit include:

1. Updating and adding definitions and making global changes in terminology;

2. Clarifying that the General Permit governs discharges to surface waters and not state waters;

3. Inserting Table 1 to clarify the timing for various required elements of Program Plan updates; Table 2 to include calculation sheets for estimating existing source loads; and Table 3 to include calculation sheets for estimating the total reduction required during the permit cycle;

4. Rewriting the Special Conditions in Section I of the General Permit to stipulate detailed strategies and processes;

5. Clarifying and expanding minimum criteria within the General Permit associated with the six minimum control measures; and

6. Providing additional clarity on what is not considered an MS4 Program modification that would require a permit modification, as well as how MS4 Program modifications may be requested by the department.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

B. This general permit will become effective on July 9, 2008 July 1, 2013, and will expire five years from the effective date consistent with 4VAC-50-60-330.

4VAC50-60-1220. Authorization to discharge.

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

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

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

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

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

3. Nonstormwater discharges or flows in the following categories identified at 4VAC50-60-400 D 2 c (3) that have not been identified by the operator, State Water Control Board, or by the board as significant contributors of pollutants to the regulated small MS4: water line flushing, landscape irrigation, diverted stream flows, rising ground waters, uncontaminated ground water infiltration, uncontaminated pumped ground water, discharges from potable water sources, foundation drains, air conditioning condensation, irrigation water, springs, water from crawl space pumps, footing drains, lawn watering, individual residential car washing, flows from riparian habitats and wetlands, dechlorinated swimming pool discharges, street wash water, and discharges or flows from fire fighting activities; or

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

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

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

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

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

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

SECTION I
DISCHARGE AUTHORIZATION AND SPECIAL CONDITIONS

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

9. Along with reporting requirements in Section II E, the operator shall include the following with each annual report:

a. Copies of any updates to the MS4 Program Plan completed during the reporting cycle and any new information regarding the TMDL in order to evaluate its ability to assure the consistency of its discharge with the assumptions of the TMDL WLA.

b. The estimate of the volume of stormwater discharged, in cubic feet, and the quantity of pollutant identified in the WLA, in a unit consistent with the WLA discharged by the regulated small MS4 for each WLA.

B. Special conditions for approved total maximum daily loads (TMDL) other than the Chesapeake Bay TMDL. An approved TMDL may allocate an applicable wasteload to a small MS4 that identifies a pollutant or pollutants for which additional stormwater controls are necessary for the surface waters to meet water quality standards. The MS4 operator shall address the pollutants in accordance with this special condition where the MS4 has been allocated a wasteload in an approved TMDL.

1. The operator shall maintain an updated MS4 Program Plan that includes a specific TMDL Action Plan for pollutants allocated to the MS4 in approved TMDLs. TMDL Action Plans may be implemented in multiple phases over more than one state permit cycle using the adaptive iterative approach provided adequate progress is demonstrated. These TMDL Actions Plans shall identify the best management practices and other implementation steps to be implemented during the remaining terms of this state permit.

a. In accordance with Table 1 in this section, the operator shall update the MS4 Program Plans to address any new or modified requirements established under this special condition for pollutants identified in TMDL wasteload allocations approved prior to July 8, 2008.

b. In accordance with Table 1 in this section, the operator shall update the MS4 Program Plan to incorporate Action Plans that identify the best management practices and other implementation steps that will be implemented during the remaining term of this permit for pollutants identified in TMDL wasteload allocations approved either on or after July 8, 2008, and prior to issuance of this permit.

c. In accordance with Table 1 in this section, the operator shall update the MS4 Program Plan with TMDL Action Plans that identify the best management practices and other steps that will be implemented during the remaining term of this state permit for pollutants identified in TMDL wasteload allocations approved after issuance of this permit for impairment listed on the 2012 § 303(d)/305(b) list and for which a TMDL schedule identifies its development as occurring during this state permit cycle.

2. The operator shall:

a. Develop and maintain a list of its legal authorities such as ordinances, state and other permits, orders, specific contract language, and interjurisdictional agreements applicable to reducing the pollutant identified in a WLA;

b. Identify and maintain an updated list of all additional management practices, control techniques and system design and engineering methods, beyond those identified in Section II B, that have been implemented as part of the MS4 Program Plan that are applicable to reducing the pollutant identified in the WLA;

c. Enhance the public education and outreach and employee training programs to also promote methods to eliminate and reduce discharges of the pollutants identified in the WLA;

d. Assess all facilities of concern owned or operated by the MS4 operator that are not covered under a separate VPDES permit and identify all municipal facilities that may be a significant source of the identified pollutant. For the purpose of this assessment, significant source is identified as facilities of concern where the pollutant discharge is expected to be greater than that average expected existing discharge for the land use identified in the TMDL. For example, the discharge of bacteria would be expected to be greater at a dog park than at other recreational facilities where dogs are prohibited.

e. Develop and implement a method to assess TMDL Action Plans for their effectiveness in reducing the pollutants identified in the WLAs. The evaluation shall use any newly available information, water quality monitoring results, or modeling tools to estimate pollutant reductions for the pollutant or pollutants of concern from implementation of the MS4 Program Plan. Monitoring may include BMP, outfall, or in-stream monitoring, as appropriate, to estimate pollutant reductions. The operator may conduct monitoring, utilize existing data, establish partnerships, or collaborate with other MS4 operators or other third parties, as appropriate. This evaluation shall include assessment of the facilities identified in subdivision 2 d of this subection. The methodology used for assessment shall be described in the TMDL Action Plan.

3. Analytical methods for any monitoring shall be conducted according to procedures approved under 40 CFR Part 136 or alternative methods approved by the Environmental Protection Agency (EPA). Where an approved 40 CFR Part 136 method does not exist, the operator must use a method consistent with the TMDL.

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

5. Annual reporting requirements.

a. The operator shall submit the required TMDL Action Plans with the appropriate annual report associated schedule identified in this state permit.

b. The operator shall report on the implementation of the TMDL Action Plans and associated evaluation including the results of any monitoring conducted as part of the evaluation.

6. The operator shall identify the best management practices and other steps that will be implemented during the next state permit term as part of the operator's reapplication for coverage as required under Section III M.

C. Special condition for the Chesapeake Bay TMDL.

SECTION II
MUNICIPAL SEPARATE STORM SEWER SYSTEM MANAGEMENT PROGRAM

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

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

B. Minimum control measures.

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

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

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

b. Increased public employee, business, and general public knowledge of hazards associated with illegal discharges and improper disposal of waste, including pertinent legal implications;

c. Increased individual and group involvement in local water quality improvement initiatives including the promotion of local restoration and clean up projects, programs, groups, meetings and other opportunities for public involvement;

d. Diverse strategies to target audiences specific to the area serviced by the regulated small MS4;

e. Improved outreach program to address viewpoints and concerns of target audiences, with a recommended focus on minorities, disadvantaged audiences and minors; and

f. Targeted strategies towards local groups of commercial, industrial, and institutional entities likely to have significant stormwater impacts.

a. The operator shall continue to implement the public education and outreach program as included in the registration statement until the program is updated to meet the conditions of this state permit. Operators who have not previously held MS4 permit coverage shall implement this program in accordance with the schedule in Table 1 of this section.

b. The public education and outreach program should be designed with consideration of the following goals:

(1) Increasing target audience knowledge about the steps that can be taken to reduce stormwater pollution, placing priority on reducing impacts to impaired waters and other local water pollution concerns;

(2) Increasing target audience knowledge of hazards associated with illegal discharges and improper disposal of waste, including pertinent legal implications; and

(3) Implementing a diverse program with strategies that are targeted towards audiences most likely to have significant stormwater impacts.

c. The updated program shall be designed to:

(1) Identify, at a minimum, three high-priority water quality issues, contributed to by the discharge of stormwater (e.g., Chesapeake Bay nutrients, pet wastes and local bacteria TMDLs, high-quality receiving waters, and illicit discharges from commercial sites) and a rationale for the selection of the three high-priority water quality issues;

(2) Identify and estimate the population size of the target audience or audiences who is most likely to have significant impacts for each high-priority water quality issue;

3. Prohibition of bypass.

a. Bypass is prohibited, and the board or its designee may take enforcement action against an operator for bypass, unless:

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

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

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

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

V. Upset.

1. An upset, as defined in 4VAC50-60-10, constitutes an affirmative defense to an action brought for noncompliance with technology based permit effluent limitations if the requirements of Section III V 2 are met. A determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is not a final administrative action subject to judicial review.

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

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

a. An upset occurred and that the operator can identify the cause(s) of the upset;

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

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

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

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

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

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

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

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

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

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

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

Y. Transfer of permits.

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

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

a. The current operator notifies the department at least two days in advance of the proposed transfer of the title to the facility or property;

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

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

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