Part II
Stormwater Management

The following stormwater management requirements apply only to seafood processors classified as Standard Industrial Classifications (SIC) Codes 2091 and 2092.

A. Monitoring and inspections.

1. Quarterly visual monitoring of stormwater quality. The permittee shall perform and document visual monitoring of stormwater discharges associated with industrial activity from each outfall, except discharges waived in subdivision d of this subsection. The visual monitoring must be made during normal working hours, at least once in each of the following three-month periods: January through March, April through June, July through September, and October through December.

a. Samples will be in clean, colorless glass or plastic containers and examined in a well-lit area;

b. Samples will be collected within the first 30 minutes (or as soon thereafter as practical, but not to exceed three hours, provided that the permittee explains in the stormwater pollution prevention plan (SWPPP) why an examination during the first 30 minutes was impractical) of when the runoff or snowmelt begins discharging. All such samples shall be collected from the discharge resulting from a storm event that results in an actual discharge from the site (defined as a "measurable storm event") providing the interval from the preceding measurable storm event is at least 72 hours. The required 72-hour storm event interval is waived where the preceding measurable storm event did not result in a measurable discharge from the facility. The 72-hour storm event interval may also be waived where the permittee documents that less than a 72-hour interval is representative for local storm events during the season when sampling is being conducted.

c. The examination shall observe color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution.

d. If no qualifying storm event resulted in discharge from the facility during a monitoring period, or adverse weather conditions create dangerous conditions for personnel during each measurable storm event during a monitoring period, visual monitoring is exempted provided this is documented in the SWPPP. Acceptable documentation includes dates and times the outfalls were viewed or sampling was attempted, national Climatic Data Center weather station data, local weather station data, facility rainfall logs, and other appropriate supporting data.

e. Representative outfalls – substantially identical stormwater discharges. If the facility has two or more outfalls that discharge substantially identical stormwater effluents, based on similarities of the industrial activities, significant materials, size of drainage areas, frequency of discharges, and stormwater management practices occurring within the drainage areas of the outfalls, the permittee may conduct quarterly visual monitoring on the stormwater discharges of just one representative outfall.

f. Visual monitoring reports shall be maintained on-site with the SWPPP. The report shall include:

(1) Outfall location;

(2) Monitoring date and time;

(3) Duration of storm event;

(4) Rainfall measurement or estimate (in inches) of the storm event that generated the discharge;

(5) Duration between the storm event sampled and the end of the previous measurable storm event;

(6) Monitoring personnel;

(7) Nature of the discharge (i.e., runoff or snow melt);

(8) Visual quality of the stormwater discharge, including observations of color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution;

(9) Probable sources of any observed stormwater contamination;

(10) Why it was not possible to take the sample within the first 30 minutes (if applicable); and

(11) Documentation to support substantially identical outfalls (if applicable) required by Part II A 1 e.

b. At least one member of the pollution prevention team shall participate in the routine facility inspections.

c. The inspection frequency shall be specified in the SWPPP based upon a consideration of the level of industrial activity at the facility but shall be at a minimum of once per calendar quarter unless written approval is received from the department for less frequent intervals. Inspections shall be performed during operating hours. At least once each calendar year, the routine facility inspection shall be conducted during a period when a stormwater discharge is occurring.

d. Any deficiencies in the implementation of the SWPPP that are found shall be corrected as soon as practicable, but not later than within 60 days of the inspection, unless permission for a later date is granted in writing by the director. The results of the inspections shall be documented in the SWPPP and shall include at a minimum:

(1) The inspection date;

(2) The names of the inspectors;

(3) Weather information and a description of any discharges occurring at the time of the inspection;

(4) Any previously unidentified discharges of pollutants from the site;

(5) Any control measures needing maintenance or repairs;

(6) Any failed control measures that need replacement;

(8) Routine external building washdown that does not use detergents or hazardous cleaning products;

(9) Uncontaminated groundwater or spring water;

(10) Foundation or footing drains where flows are not contaminated with process materials; and

(11) Incidental windblown mist from cooling towers that collects on rooftops or adjacent portions of the facility, but not intentional discharges from the cooling tower (e.g., "piped" cooling tower blowdown or drains).

B. Corrective actions. The permittee shall take corrective action whenever:

1. Routine facility inspections, visual monitoring, inspections by local, state, or federal officials, or any other process, observation, or event result in a determination that modifications to the stormwater control measures are necessary to meet the permit requirements;

2. The department determines, or the permittee becomes aware, that the stormwater control measures are not stringent enough for the discharge to meet applicable water quality standards.

3. The permittee shall review the SWPPP and modify it as necessary to address any deficiencies. Revisions to the SWPPP shall be completed within 60 days following the discovery of the deficiency. When control measures need to be modified or added, implementation shall be completed before the next anticipated storm event if possible, but no later than 60 days after the deficiency is discovered, or as otherwise provided or approved by the department. In cases where construction is necessary to implement control measures, the permittee shall include a schedule in the SWPPP that provides for the completion of the control measures as expeditiously as practicable, but no later than three years after the deficiency is discovered. Where a construction compliance schedule is included in the SWPPP, the SWPPP shall include appropriate nonstructural and temporary controls to be implemented in the affected portion of the facility prior to completion of the permanent control measure.

(2) Control measures generally must be used in combination with each other for most effective water quality protection;

(3) Assessing the type and quantity of pollutants, including their potential to impact receiving water quality, is critical to designing effective control measures;

(4) That minimizing impervious areas at the facility can reduce runoff and improve groundwater recharge and stream base flows in local streams (however, care must be taken to avoid groundwater contamination);

(5) Flow attenuation by use of open vegetated swales and natural depressions can reduce instream impacts of erosive flows;

(6) Conservation or restoration of riparian buffers will help protect streams from stormwater runoff and improve water quality; and

(7) Treatment interceptors (e.g., swirl separators and sand filters) may be appropriate in some instances to minimize the discharge of pollutants.

e. Control measures. The permittee shall implement the following types of control measures to prevent and control pollutants in the stormwater discharges from the facility, unless it can be demonstrated and documented that such controls are not relevant to the discharges.

(1) Good housekeeping. The permittee shall keep clean all exposed areas of the facility that are potential sources of pollutants to stormwater discharges. The permittee shall perform the following good housekeeping measures to minimize pollutant discharges:

(a) The SWPPP shall include a schedule for regular pickup and disposal of waste materials along with routine inspections for leaks and conditions of drums, tanks, and containers;

(b) Sweep or vacuum as feasible;

(d) Manage all waste containers to prevent a discharge of pollutants;

(e) Minimize the potential for waste, garbage, and floatable debris to be discharged by keeping areas exposed to stormwater free of such materials or by intercepting such materials prior to discharge; and

(f) Implement BMPs to eliminate stormwater discharges of plastics.

(2) Eliminating and minimizing exposure. To the extent practicable, manufacturing, processing, and material storage areas, including loading and unloading, storage, disposal, cleaning, maintenance, and fueling operations, shall be located inside, or protected by a storm-resistant covering to prevent exposure to rain, snow, snowmelt, and runoff. Unless infeasible, facilities shall implement the following:

(a) Use grading, berming, or curbing to prevent runoff of contaminated flows and divert run-on away from potential sources of pollutants;

(b) Locate materials, equipment, and activities so that potential leaks and spills are contained, or able to be contained, or diverted before discharge;

(c) Clean up spills and leaks immediately, upon discovery of the spills or leaks, using dry methods (e.g., absorbents) to prevent the discharge of pollutants;

(d) Store leaking vehicles and equipment indoors, or if stored outdoors, use drip pans and adsorbents;

(e) Utilize appropriate spill or overflow protections equipment;

(f) Perform all vehicle maintenance or equipment cleaning operations indoors, under cover, or in bermed areas that prevent runoff and run-on and also capture any overspray; and

(g) Drain fluids from equipment and vehicles that will be decommissioned, and for any equipment and vehicles that remain unused for extended periods of time, inspect at least monthly for leaks.

(3) Preventive maintenance. The SWPPP shall include preventive maintenance that includes a description of procedures and a regular schedule for inspection of the following:

(a) All control measures that includes a description of the back-up practices that are in place should a runoff event occur while a control measure is off line; and

(b) Testing, maintenance, and repairing of all industrial equipment and systems to avoid situations that could result in leaks, spills, and other releases of pollutants in stormwater discharged from the facility.

(4) Spill prevention and response procedures. The SWPPP shall describe the procedures that will be followed for preventing and responding to spills and leaks, including:

(a) Preventive measures, such as barriers between material storage and traffic areas, secondary containment provisions, and procedures for material storage and handling;

(b) Response procedures, including notification of appropriate facility personnel, emergency agencies, and regulatory agencies and procedures for stopping, containing, and cleaning up spills. Measures for cleaning up hazardous material spills or leaks shall be consistent with applicable the Resource Conservation and Recovery Act regulations at 40 CFR Part 264 and 40 CFR Part 265. Employees who may cause, detect, or respond to a spill or leak shall be trained in these procedures and have necessary spill response equipment available. If possible, one of these individuals shall be a member of the pollution prevention team;

(c) Procedures for plainly labeling containers (e.g., "used oil," "spent solvents," and "fertilizers and pesticides") that could be susceptible to spillage or leakage to encourage proper handling and facilitate rapid response if spills or leaks occur; and

(d) Contact information for individuals and agencies that must be notified in the event of a spill shall be included in the SWPPP and maintained in other locations where it will be readily available.

(5) Employee training. The permittee shall implement a stormwater employee training program for the facility. The SWPPP shall include a schedule for all training and shall document all training sessions and the employees who received the training. Training shall be provided at least annually for all employees who work in areas where industrial materials or activities are exposed to stormwater, and for employees who are responsible for implementing activities identified in the SWPPP (e.g., inspectors and maintenance personnel). The training shall cover the components and goals of the SWPPP and include such topics as spill response, good housekeeping, material management practices, BMP operation and maintenance and pest control. The SWPPP shall include a summary of any training performed.

(6) Sediment and erosion control. The SWPPP shall identify areas at the facility that, due to topography, land disturbance (e.g., construction, landscaping, site grading), or other factors, have a potential for soil erosion. The permittee shall identify and implement structural, vegetative, or stabilization control measures to prevent or control on-site and off-site erosion and sedimentation. Flow velocity dissipation devices shall be placed at discharge locations and along the length of any outfall channel if the flows would otherwise create erosive conditions.

(7) Management of runoff. The plan shall describe the stormwater runoff management practices (i.e., permanent structural control measures) for the facility. These types of control measures shall be used to divert, infiltrate, reuse, or otherwise reduce pollutants in stormwater discharges from the site.

Structural control measures may require a separate permit under § 404 of the federal Clean Water Act and the Virginia Water Protection Permit Program Regulation (9VAC25-210) before installation begins.

If the permittee monitors any pollutant specifically addressed by this permit more frequently than required by this permit using test procedures approved under 40 CFR Part 136 or using other test procedures approved by the U.S. Environmental Protection Agency or using procedures specified in this 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.

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

D. Duty to provide information. The 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 coverage under this permit or to determine compliance with this 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 the permittee's discharge on the quality of state waters, or such other information as may be necessary to accomplish the purposes of the State Water Control Law. The permittee shall also furnish to the department, upon request, copies of records required to be kept by this permit.

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

F. Unauthorized discharges. Except in compliance with this permit or another permit issued by the board, it shall be unlawful for any person to:

1. Discharge into state waters sewage, industrial wastes, other wastes, or any noxious or deleterious substances; or

2. Otherwise alter the physical, chemical or biological properties of such state waters and make them detrimental to the public health, or to animal or aquatic life, or to the use of such waters for domestic or industrial consumption, or for recreation, or for other uses.

G. Reports of unauthorized discharges. Any permittee who discharges or causes or allows a discharge of sewage, industrial waste, other wastes or any noxious or deleterious substance into or upon state waters in violation of Part III F (Unauthorized discharges); or who discharges or causes or allows a discharge that may reasonably be expected to enter state waters in violation of Part III F, shall notify (see Part III I 3) the department of the discharge immediately upon discovery of the discharge, but in no case later than 24 hours after said discovery. A written report of the unauthorized discharge shall be submitted to the department within five days of discovery of the discharge. The written report shall contain:

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

2. The cause of the discharge;

3. The date on which the discharge occurred;

4. The length of time that the discharge continued;

5. The volume of the discharge;

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

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

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

Discharges reportable to the department under the immediate reporting requirements of other regulations are exempted from this requirement.

H. Reports of unusual or extraordinary discharges. If any unusual or extraordinary discharge including a bypass or upset, should occur from a treatment works and the discharge enters or could be expected to enter state waters, the permittee shall promptly notify, in no case later than 24 hours, the department by telephone after the discovery of the 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 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 Part III I 2. Unusual and extraordinary discharges include any discharge resulting from:

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

2. Breakdown of processing or accessory equipment;

3. Failure or taking out of service some or all of the treatment works; and

4. Flooding or other acts of nature.

I. Reports of noncompliance.

1. The permittee shall report any noncompliance that may adversely affect state waters or may endanger public health.

a. An oral report shall be provided within 24 hours from the time the permittee becomes aware of the circumstances. The following shall be included as information that shall be reported within 24 hours under this subdivision:

(1) Any unanticipated bypass; and

(2) Any upset that causes a discharge to surface waters.

b. A written report shall be submitted within five days and shall contain:

(1) A description of the noncompliance and its cause;

(2) 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

(3) Steps taken or planned to reduce, eliminate, and prevent reoccurrence of the noncompliance.

The board may waive the written report on a case-by-case basis for reports of noncompliance under Part III I if the oral report has been received within 24 hours and no adverse impact on state waters has been reported.

2. The permittee shall report all instances of noncompliance not reported under Part III I 1 or 2, in writing, at the time the next monitoring reports are submitted. The reports shall contain the information listed in Part III I 2.

3. The immediate (within 24 hours) reports required in Part III G, H, and I may be made to the department's regional office. Reports may be made by telephone, or online at https://www.deq.virginia.gov/our-programs/pollution-response.

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

J. Notice of planned changes.

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 permittee plans alteration or addition to any building, structure, facility, or installation from which there is or may be a discharge of pollutants, the construction of which commenced:

(1) After promulgation of standards of performance under § 306 of the federal Clean Water Act that are applicable to such source; or

(2) After proposal of standards of performance in accordance with § 306 of the federal Clean Water Act that are applicable to such source, but only if the standards are promulgated in accordance with § 306 within 120 days of their proposal;

b. The alteration or addition could significantly change the nature or increase the quantity of pollutants discharged. This notification applies to pollutants that are subject neither to effluent limitations nor to notification requirements specified under Part I B 6; or

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 registration 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 that may result in noncompliance with permit requirements.

K. Signatory requirements.

1. Registration statement. All registration statements shall be signed as follows:

a. For a corporation: by a responsible corporate officer. For the purposes 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 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 other 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;

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

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

2. Reports and other information. All reports required by permits, and other information requested by the board, shall be signed by a person described in Part III K 1 or by a duly authorized representative of that person. A person is a duly authorized representative only if:

a. The authorization is made in writing by a person described in Part III K 1;

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

c. The written authorization is submitted to the department.

3. Changes to authorization. If an authorization under Part III K 2 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 Part III K 2 shall be submitted to the department prior to or together with any reports or information to be signed by an authorized representative.

4. Certification. Any person signing a document under Part III K 1 or 2 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."

L. Duty to comply. The permittee shall comply with all conditions of this permit. Any permit noncompliance constitutes a violation of the State Water Control Law and the federal Clean Water Act, except that noncompliance with certain provisions of this permit may constitute a violation of the State Water Control Law but not the federal Clean Water Act. Permit noncompliance is grounds for enforcement action; for permit coverage termination or denial of a permit renewal.

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

M. Duty to reapply. If the permittee wishes to continue an activity regulated by this permit after the expiration date of this permit, the permittee shall submit a new registration statement at least 60 days before the expiration date of the existing permit, unless permission for a later date has been granted by the board. The board shall not grant permission for registration statements to be submitted later than the expiration date of the existing permit.

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

O. State law. Nothing in this permit shall be construed to preclude the institution of any legal action under, or relieve the permittee from any responsibilities, liabilities, or penalties established pursuant to, any other state law or regulation or under authority preserved by § 510 of the federal Clean Water Act. Except as provided in permit conditions in Part III U (Bypass) and Part III V (Upset) nothing in this permit shall be construed to relieve the permittee from civil and criminal penalties for noncompliance.

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

Q. Proper operation and maintenance. The 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 permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes effective plant performance, adequate funding, adequate staffing, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems that are installed by the permittee only when the operation is necessary to achieve compliance with the conditions of this permit.

R. Disposal of solids or sludges. Solids, sludges, or other pollutants removed in the course of treatment or management of pollutants shall be disposed of in a manner so as to prevent any pollutant from such materials from entering state waters.

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

T. Need to halt or reduce activity not a defense. It shall not be a defense for 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 this permit.

U. Bypass.

1. "Bypass" means the intentional diversion of waste streams from any portion of a treatment facility. The 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 ensure efficient operation. These bypasses are not subject to the provisions of Part III U 2 and U 3.

2. Notice.

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

b. Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Part III I (Reports of noncompliance).

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 that occurred during normal periods of equipment downtime or preventive maintenance; and

(3) The permittee submitted notices as required under Part III U 2.

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 Part III U 3 a.

V. Upset.

1. An upset, defined in 9VAC25-31-10, constitutes an affirmative defense to an action brought for noncompliance with technology-based permit effluent limitations if the requirements of Part 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. A permittee that 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 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 Part III I; and

d. The permittee complied with any remedial measures required under Part III S.

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

W. Inspection and entry. 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 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 ensuring permit compliance or as otherwise authorized by the federal Clean Water Act and the State Water Control Law, any substances or parameters at any location.

For purposes of this section, the time for inspection shall be deemed reasonable during regular business hours or 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 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.

Y. Transfer of permit coverage.

1. Permit coverage is not transferable to any person except after notice to the department.

2. Coverage under this permit may be automatically transferred to a new permittee if:

a. The current permittee notifies the department within 30 days of the transfer of the title to the facility or property unless permission for a later date has been granted by the board;

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

c. The board does not notify the existing permittee and the proposed new permittee of its intent to deny the permittee coverage under the permit. If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in Part III Y 2.

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.

General Permit No.: VAR05

Effective Date: July 1, 2024

Expiration Date: June 30, 2029

VPDES GENERAL PERMIT FOR STORMWATER DISCHARGES ASSOCIATED WITH INDUSTRIAL ACTIVITY

AUTHORIZATION TO DISCHARGE UNDER THE VIRGINIA POLLUTANT DISCHARGE ELIMINATION SYSTEM AND THE VIRGINIA STATE WATER CONTROL LAW

In compliance with the provisions of the Clean Water Act, as amended, and pursuant to the State Water Control Law and regulations adopted pursuant thereto, owners of facilities with stormwater discharges associated with industrial activity are authorized to discharge to surface waters within the boundaries of the Commonwealth of Virginia, except those waters specifically named in board regulation that prohibit such discharges.

The authorized discharge shall be in accordance with this cover page, the registration statement, Part I-Effluent Limitations, Monitoring Requirements and Special Conditions, Part II-Conditions Applicable to All VPDES Permits, Part III-Stormwater Pollution Prevention Plan, Part IV-Sector-Specific Permit Requirements, and Part V-Chesapeake Bay Total Maximum Daily Load Compliance as set forth in this general permit.

Part I

Effluent Limitations, Monitoring Requirements and Special Conditions

A. Effluent limitations and monitoring requirements.

There are four individual and separate categories of monitoring requirements that a facility may be subject to under this permit: (i) quarterly visual monitoring; (ii) benchmark monitoring of discharges associated with specific industrial activities; (iii) compliance monitoring for discharges subject to numerical effluent limitations; and (iv) monitoring of discharges to impaired waters, both those with an approved TMDL and those without an approved TMDL. The monitoring requirements and numeric effluent limitations applicable to a facility depend on the types of industrial activities generating stormwater runoff from the facility, and for TMDL monitoring, the location of the facility's discharge. Part IV of the permit identifies monitoring requirements applicable to specific sectors of industrial activity. The permittee shall review Part I A 1 and Part IV of the permit to determine which monitoring requirements and numeric limitations apply to the permittee's facility. Unless otherwise specified, limitations and monitoring requirements under Part I A 1 and Part IV are additive.

Sector-specific monitoring requirements and limitations are applied discharge by discharge at facilities with colocated activities. Where stormwater from the colocated activities is commingled, the monitoring requirements and limitations are additive. Where more than one numeric limitation for a specific parameter applies to a discharge, compliance with the more restrictive limitation is required. Where benchmark, numerical effluent limitations, or TMDL monitoring requirements for a monitoring period overlap, the permittee may use a single sample to satisfy monitoring requirements.

1. Types of monitoring requirements and limitations.

a. Quarterly visual monitoring. The requirements and procedures for quarterly visual monitoring are applicable to all facilities covered under this permit, regardless of the facility's sector of industrial activity.

(1) The permittee shall perform and document a quarterly visual examination of a stormwater discharge associated with industrial activity from each outfall, except discharges exempted in Part I A 3 or A 4. The visual examinations shall be made at least once in each of the following three-month periods: January through March, April through June, July through September, and October through December. The visual examination shall be made during normal working hours, where practicable, and when considerations for safety and feasibility allow. If no storm event resulted in runoff from the facility during a monitoring quarter, the permittee is excused from visual monitoring for that quarter provided that documentation is included with the monitoring records indicating that no runoff occurred.

(2) Samples shall be collected in accordance with Part I A 2. Sample examination shall document observations of color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution. The visual examination of the sample shall be conducted in a well-lit area. No analytical tests are required to be performed on the samples.

(3) The visual examination documentation shall be maintained on-site with the SWPPP. The documentation shall include the outfall location, the examination date and time, examination staff, the nature of the discharge (i.e., runoff or snow melt), visual quality of the stormwater discharge (including observations of color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution), and probable sources of any observed stormwater contamination.

b. Benchmark monitoring of discharges associated with specific industrial activities.

Table 70-1 identifies the specific industrial sectors subject to the benchmark monitoring requirements of this permit and the industry-specific pollutants of concern. The permittee shall refer to the tables found in the individual sectors in Part IV for benchmark monitoring concentration values. Colocated industrial activities at the facility that are described in more than one sector in Part IV shall comply with all applicable benchmark monitoring requirements from each sector.

The results of benchmark monitoring are primarily for the permittee to use to determine the overall effectiveness of the SWPPP in controlling the discharge of pollutants to receiving waters. Benchmark concentration values, included in Part IV of this permit, are not effluent limitations. Exceedance of a benchmark concentration does not constitute a violation of this permit and does not show that violation of a water quality standard has occurred; however, it does signal that modifications to the SWPPP are necessary, unless justification is provided in a routine facility inspection. In addition, exceedance of benchmark concentrations may identify facilities that would be more appropriately covered under an individual, or alternative general permit where more specific pollution prevention controls could be required.

¹Table does not include parameters for compliance monitoring under effluent limitations guidelines. ²See Sector G (Part IV G) for additional monitoring discharges from waste rock and overburden piles from active ore mining or dressing facilities, inactive ore mining or dressing facilities, and sites undergoing reclamation.

(1) Benchmark monitoring shall be performed for all benchmark parameters specified for the industrial sector applicable to a facility's discharge. Monitoring shall be performed at least once during each of the first four, and potentially all, monitoring periods after coverage under the permit begins. Monitoring begins with the first full monitoring period after the owner is granted coverage under the permit. Monitoring periods are specified in Part I A 2.

(2) Benchmark monitoring waivers for facilities testing below benchmark concentration values. Waivers from benchmark monitoring are available to facilities whose discharges are below benchmark concentration values on an outfall by outfall basis. Sector-specific benchmark monitoring is not required to be conducted in subsequent monitoring periods during the term of this permit provided:

(a) Samples were collected in four consecutive monitoring periods, and the average of the four samples for all parameters at the outfall is below the applicable benchmark concentration value in Part IV. Facilities that were covered under the 2019 industrial stormwater general permit may use sampling data from the last two monitoring periods of that permit and the first two monitoring periods of this permit to satisfy the four consecutive monitoring periods requirement;

(b) The facility is not subject to a numeric effluent limitation established in Part I A 1 c (1) (stormwater effluent limitations), Part I A 1 c (2) (coal pile runoff), or Part IV (Sector Specific Permit Requirements) for any of the parameters at that outfall; and

(c) A waiver request is submitted to and approved by the department. The waiver request shall be sent to the appropriate DEQ regional office, along with the supporting monitoring data for four consecutive monitoring periods, and a certification that, based on current potential pollutant sources and control measures used, discharges from the facility are reasonably expected to be substantially similar or cleaner compared to when the benchmark monitoring for the four consecutive monitoring periods was done.

Waiver requests will be evaluated by the department based on (i) benchmark monitoring results below the benchmark concentration values; (ii) a favorable compliance history (including inspection results); and (iii) no outstanding enforcement actions.

The monitoring waiver may be revoked by the department for cause. The permittee will be notified in writing that the monitoring waiver is revoked, and that the benchmark monitoring requirements are again in force and will remain in effect until the permit's expiration date.

(3) Samples shall be collected and analyzed in accordance with Part I A 2. Monitoring results shall be reported in accordance with Part I A 5 and Part II C and retained in accordance with Part II B.

c. Compliance monitoring for discharges subject to numerical effluent limitations or discharges to impaired waters.

(1) Facilities subject to stormwater effluent limitation guidelines.

(a) Facilities subject to stormwater effluent limitation guidelines (see Table 70-2) are required to monitor the discharges to evaluate compliance with numerical effluent limitations. Industry-specific numerical limitations and compliance monitoring requirements are described in Part IV of the permit. Permittees with colocated industrial activities at the facility that are described in more than one sector in Part IV shall comply on a discharge-by-discharge basis with all applicable effluent limitations from each sector.

(b) Permittees shall monitor the discharges for the presence of the pollutant subject to the effluent limitation at least once during each of the monitoring periods after coverage under the permit begins. Monitoring begins with the first full monitoring period after the owner is granted coverage under the permit. Monitoring periods are specified in Part I A 2. The substantially identical outfall monitoring provisions (Part I A 2 f) are not available for numeric effluent limits monitoring.

(c) Samples shall be collected and analyzed in accordance with Part I A 2. Monitoring results shall be reported in accordance with Part I A 5 and Part II C, and retained in accordance with Part II B.

Discharges from airport deicing operations (40 CFR Part 449 (established May 16, 2012))	Facilities subject to the effluent limitation guidelines in 40 CFR Part 449 may be covered under Sector AD.

(2) Facilities subject to coal pile runoff monitoring.

(a) Facilities with discharges of stormwater from coal storage piles shall comply with the limitations and monitoring requirements of Table 70-3 for all discharges containing the coal pile runoff, regardless of the facility's sector of industrial activity.

(b) Permittees shall monitor the stormwater discharges at least once during each of the monitoring periods after coverage under the permit begins. Monitoring begins with the first full monitoring period after the owner is granted coverage under the permit. Monitoring periods are specified in Part I A 2. The substantially identical outfall monitoring provisions (Part I A 2 f) are not available for coal pile numeric effluent limits monitoring.

(d) If a facility is designed, constructed, and operated to treat the volume of coal pile runoff that is associated with a 10-year, 24-hour rainfall event, any untreated overflow of coal pile runoff from the treatment unit is not subject to the 50 mg/L limitation for total suspended solids.

(e) Samples shall be collected and analyzed in accordance with Part I A 2. Monitoring results shall be reported in accordance with Part I A 5 and Part II C, and retained in accordance with Part II B.

TABLE 70-3 NUMERIC LIMITATIONS FOR COAL PILE RUNOFF
Parameter	Limit	Monitoring Frequency	Sample Type
Total Suspended Solids (TSS)	50 mg/l, max.	1/6 months	Grab
pH	6.0 min. - 9.0 max.	1/6 months	Grab

(3) Facilities discharging to an impaired water with an approved TMDL wasteload allocation. Owners of facilities that are a source of the specified pollutant of concern to waters for which a TMDL wasteload allocation has been approved by the U.S. Environmental Protection Agency (EPA) before the term of this permit will be notified by the department when they are approved for coverage under the general permit.

(a) Upon written notification from the department, permittees shall monitor the discharges for the pollutant subject to TMDL wasteload allocation once every six months after coverage under the permit begins, unless another sampling frequency is determined by the department for polychlorinated biphenyls (PCBs). Monitoring begins with the first full monitoring period after the owner is granted coverage under the permit. Monitoring periods are specified in Part I A 2.

(b) Samples shall be collected and analyzed in accordance with Part I A 2. Monitoring results shall be reported in accordance with Part I A 5 and Part II C, and retained in accordance with Part II B.

(c) If the pollutant subject to the TMDL wasteload allocation is below the quantitation level in all of the samples from the first four monitoring periods, the permittee may request to the department in writing that further sampling be discontinued, unless the TMDL has specific instructions to the contrary (in which case those instructions shall be followed). The laboratory certificate of analysis shall be submitted with the request. If approved, documentation of this shall be kept with the SWPPP.

If the pollutant subject to the TMDL wasteload allocation is above the quantitation level in any of the samples from the first four monitoring periods, the permittee shall continue the scheduled TMDL monitoring throughout the term of the permit. Applicable sampling data collected during the 2019 industrial stormwater general permit term may be used to satisfy all or part of the four monitoring periods requirement.

(d) Upon written notification from the department, facilities exceeding the TMDL wasteload allocation shall prepare and submit a pollutant minimization plan (PMP) designed to investigate the location and potential reduction of sources in the facility's stormwater discharges. The PMP shall be developed and submitted to the department for approval within 180 days of the receipt of notification from the department. The PMP shall include the following items, as appropriate:

(i) Facility contact for the contents of the PMP and any activities associated with the PMP;

(ii) A proposed implementation schedule for minimization activities and prospective milestones;

(iii) Proposed actions for known or probable sources;

(iv) Proposed action to find and control unknown sources;

(v) A summary of any previous minimization activities; and

(vi) Information on continuing assessment of progress, which may include establishment of criteria to evaluate whether the location and potential reduction of sources have been addressed.

(4) Facilities discharging to an impaired water without an approved TMDL wasteload allocation. Owners of facilities that discharge to waters listed as impaired in the 2022 Final 305(b)/303(d) Water Quality Assessment Integrated Report, and for which a TMDL wasteload allocation has not been approved before the term of this permit, will be notified by the department when they are approved for coverage under the general permit.

(a) Upon written notification from the department,

permittees shall monitor the discharges for all pollutants for which the waterbody is impaired, and for which a standard analytical method exists, at least once every six months after coverage under the permit begins, unless otherwise determined by the department for polychlorinated biphenyls (PCBs). Monitoring begins with the first full monitoring period after the owner is granted coverage under the permit. Monitoring periods are specified in Part I A 2.

(b) If the pollutant for which the waterbody is impaired is suspended solids, turbidity, or sediment, or sedimentation, monitor for total suspended solids (TSS). If the pollutant for which the waterbody is impaired is expressed in the form of an indicator or surrogate pollutant, monitor for that indicator or surrogate pollutant. No monitoring is required when a waterbody's biological communities are impaired but no pollutant, including indicator or surrogate pollutants, is specified as causing the impairment, or when a waterbody's impairment is related to hydrologic modifications, impaired hydrology, or temperature. Samples shall be collected and analyzed in accordance with Part I A 2. Monitoring results shall be reported in accordance with Part I A 5 and Part II C, and retained in accordance with Part II B.

(c) If the pollutant for which the water is impaired is below the quantitation level in the discharges from the facility, or it is above the quantitation level but its presence is caused solely by natural background sources, the permittee may request to the department in writing that further impaired water monitoring be discontinued. The laboratory certificate of analysis shall be submitted with the request. If approved, documentation of this shall be kept with the SWPPP.

To support a determination that the pollutant's presence is caused solely by natural background sources, the following documentation shall be submitted with the request and kept with the SWPPP: (i) an explanation of why it is believed that the presence of the impairment pollutant in the facility's discharge is not related to the activities at the facility; and (ii) data or studies that tie the presence of the impairment pollutant in the facility's discharge to natural background sources in the watershed. Natural background pollutants include those substances that are naturally occurring in soils or groundwater. Natural background pollutants do not include legacy pollutants from earlier activity at the facility's site or pollutants in run-on from neighboring sources that are not naturally occurring.

2. Monitoring instructions.

a. Collection and analysis of samples. Sampling requirements shall be assessed on an outfall by outfall basis. Samples shall be collected and analyzed in accordance with the requirements of Part II A.

b. When and how to sample. A minimum of one grab sample shall be taken from the discharge associated with industrial activity resulting from a storm event that results in a discharge from the site, providing the interval from the preceding storm event discharge is at least 72 hours. The 72-hour storm interval is waived if the permittee is able to document that less than a 72-hour interval is representative for local storm events during the sampling period. In the case of snowmelt, the monitoring shall be performed at a time when a measurable discharge occurs at the site. For discharges from a stormwater management structure, the monitoring shall be performed at a time when a measurable discharge occurs from the structure.

The grab sample shall be taken during the first 30 minutes of the discharge. If it is not practicable to take the sample during the first 30 minutes, the sample may be taken during the first three hours of the discharge, provided that the permittee explains why a grab sample during the first 30 minutes was impracticable. This information shall be submitted in the department's electronic discharge monitoring report (e-DMR) system, and maintained with the SWPPP. If the sampled discharge commingles with process or nonprocess water, the permittee shall attempt to sample the stormwater discharge before it mixes with the nonstormwater.

c. Storm event data. For each monitoring event (except snowmelt monitoring), along with the monitoring results, the permittee shall identify the date of the storm event sampled; rainfall total (in inches) of the storm event that generated the sampled runoff; and the interval between the storm event sampled and the end of the previous storm event discharge. For snowmelt monitoring, the permittee shall identify the date of the sampling event.

d. Monitoring periods.

(1) Quarterly visual monitoring. The quarterly visual examinations shall be made at least once in each of the following three-month periods each year of permit coverage: January through March, April through June, July through September, and October through December.

(2) Benchmark monitoring, effluent limitation monitoring, and impaired waters monitoring (for waters both with and without an approved TMDL). Monitoring shall be conducted at least once in each of the following semiannual periods each year of permit coverage: January through June, and July through December.

e. Documentation explaining a facility's inability to obtain a sample (including dates and times the outfalls were viewed or sampling was attempted), of no rain event, or of deviation from the 72-hour storm interval shall be submitted with the e-DMR and maintained with the SWPPP. Acceptable documentation includes National Climatic Data Center (NCDC) weather station data, local weather station data, facility rainfall logs, and other appropriate supporting data.

f. Representative outfalls - substantially identical discharges. If the facility has two or more outfalls that discharge substantially identical effluents, based on similarities of the industrial activities, significant materials, size of drainage areas, and stormwater management practices occurring within the drainage areas of the outfalls, frequency of discharges, and stormwater management practices occurring within the drainage areas of the outfalls, the permittee may conduct monitoring on the effluent of just one of the outfalls and report that the observations also apply to the substantially identical outfall. The substantially identical outfall monitoring provisions apply to quarterly visual monitoring, benchmark monitoring, and impaired waters monitoring (both those with and without an approved TMDL). The substantially identical outfall monitoring provisions are not available for numeric effluent limits monitoring. The permittee shall include the following information in the SWPPP:

(1) The locations of the outfalls;

(2) An evaluation, including available monitoring data, indicating the outfalls are expected to discharge substantially identical effluents, including evaluation of monitoring data where available; and

(3) An estimate of the size of each outfall's drainage area in acres.

3. Adverse climatic conditions waiver. When adverse weather conditions prevent the collection of samples, a substitute sample may be taken during a qualifying storm event in the next monitoring period. Adverse weather conditions are those that are dangerous or create inaccessibility for staff and may include local flooding, high winds, electrical storms, or situations that otherwise make sampling impracticable (e.g., drought or extended frozen conditions). Unless specifically stated otherwise, this waiver may be applied to any monitoring required under this permit. Narrative documentation of conditions necessitating the use of the waiver shall be kept with the SWPPP.

4. Inactive and unstaffed sites (including temporarily inactive sites).

a. A waiver of the quarterly visual monitoring, routine facility inspections, and monitoring requirements (including benchmark, effluent limitation, and impaired waters monitoring) may be granted by the department at a facility that is both inactive and unstaffed, as long as the facility remains inactive and unstaffed and there are no industrial materials or activities exposed to stormwater. The owner of the facility is only required to conduct an annual routine site inspection in accordance with the requirements in Part III B 5.

b. An inactive and unstaffed sites waiver request shall be submitted to the department for approval and shall include the name of the facility; the facility's VPDES general permit registration number; a contact person, telephone number, and email address; the reason for the request; and the date the facility became or will become inactive and unstaffed. The waiver request shall be signed and certified in accordance with Part II K. If this waiver is granted, a copy of the request and the department's written approval of the waiver shall be maintained with the SWPPP.

c. If circumstances change and industrial materials or activities become exposed to stormwater or the facility becomes either active or staffed, the permittee shall notify the department within 30 days, and all quarterly visual monitoring, routine facility inspections, and monitoring requirements shall be resumed immediately.

d. The department retains the right to revoke this waiver when it is determined that the discharge is causing, has a reasonable potential to cause, or contributes to a water quality standards violation.

e. Inactive and unstaffed facilities covered under Sector G (Metal Mining) and Sector H (Coal Mines and Coal Mining-Related Facilities) are not required to meet the "no industrial materials or activities exposed to stormwater" standard to be eligible for this waiver, consistent with the conditional exemption requirements established in Part IV Sector G and Part IV Sector H.

5. Reporting monitoring results.

a. Reporting to the department. The permittee shall follow the reporting requirements and deadlines in Table 70-4 for the types of monitoring that apply to the facility:

TABLE 70-4 MONITORING REPORTING REQUIREMENTS
Semiannual Monitoring	Submit the results by January 10 and by July 10.
Quarterly Visual Monitoring	Retain results with SWPPP - do not submit unless requested to do so by the department.

Permittees shall submit results for each outfall associated with industrial activity according to the requirements of Part II C.

b. Significant digits. The permittee shall report at least the same number of significant digits as a numeric effluent limitation or TMDL wasteload allocation for a given parameter; otherwise, at least two significant digits shall be reported for a given parameter. Regardless of the rounding convention used by the permittee (i.e., five always rounding up or to the nearest even number), the permittee shall use the convention consistently and shall ensure that consulting laboratories employed by the permittee use the same convention.

6. Corrective actions.

a. The permittee shall take corrective action whenever:

(1) Routine facility inspections, inspections by local, state or federal officials, or any other process, observation or event result in a determination that modifications to the stormwater control measures are necessary to meet the permit requirements;

(2) There is any exceedance of an effluent limitation (including coal pile runoff), TMDL wasteload allocation, or a reduction required by a local ordinance established by a municipality to meet Chesapeake Bay TMDL requirements;

(3) The department determines, or the permittee becomes aware, that the stormwater control measures are not stringent enough for the discharge to meet applicable water quality standards; or

(4) Benchmark monitoring results exceed the benchmark concentration value for a parameter.

The permittee shall review the SWPPP and modify it as necessary to address any deficiencies. Revisions to the SWPPP shall be completed within 60 days following the discovery of the deficiency. When control measures need to be modified or added (distinct from regular preventive maintenance of existing control measures described in Part III C), implementation shall be completed before the next anticipated storm event if possible, but no later than 60 days after the deficiency is discovered, or as otherwise provided or approved by the department. In cases where construction is necessary to implement control measures, the permittee shall include a schedule in the SWPPP that provides for the completion of the control measures as expeditiously as practicable, but no later than three years after the deficiency is discovered. Where a construction compliance schedule is included in the SWPPP, the SWPPP shall include appropriate nonstructural and temporary controls to be implemented in the affected portion of the facility before completion of the permanent control measure. Any corrective actions taken shall be documented and retained with the SWPPP. Any control measure modifications shall be dated and document the amount of time taken to modify the applicable control measures or implement additional control measures.

b. Natural background pollutant levels. If the concentration of a pollutant exceeds a benchmark concentration value and the permittee determines that exceedance of the benchmark is attributable solely to the presence of that pollutant in the natural background, corrective action is not required provided that:

(1) The concentration of the benchmark monitoring result is less than or equal to the concentration of that pollutant in the natural background;

(2) The permittee documents and maintains with the SWPPP the supporting rationale for concluding that benchmark exceedances are in fact attributable solely to natural background pollutant levels. The supporting rationale shall include any data previously collected by the facility or others (including literature studies) that describe the levels of natural background pollutants in the facility's stormwater discharges; and

(3) The permittee notifies the department on the benchmark monitoring DMR that the benchmark exceedances are attributable solely to natural background pollutant levels. Natural background pollutants include those substances that are naturally occurring in soils or groundwater. Natural background pollutants do not include legacy pollutants from earlier activity on the facility's site, or pollutants in run-on from neighboring sources that are not naturally occurring.

c. Follow-up reporting. If at any time monitoring results show that discharges from the facility exceed an effluent limitation or a TMDL wasteload allocation, or the department determines that discharges from the facility are causing or contributing to an exceedance of a water quality standard, immediate steps shall be taken to eliminate the exceedances in accordance with Part I A 6. Within 30 calendar days of implementing the relevant corrective action, an exceedance report shall be submitted to the department and shall be signed in accordance with Part II K. The following information shall be included in the report:

(1) General permit registration number;

(2) Facility name and address;

(3) Receiving water for each outfall exceeding an effluent limitation of TMDL wasteload allocation;

(4) Monitoring data from the event being reported;

(5) A narrative description of the situation;

(6) A description of actions taken since the event was discovered and steps taken to minimize to the extent feasible pollutants in the discharge; and

(7) A local facility contact name, email address, and phone number.

B. Special conditions.

1. Authorized nonstormwater discharges. Except as provided in this section or in Part IV, all discharges covered by this permit shall be composed entirely of stormwater. The following nonstormwater discharges are authorized by this permit:

a. Discharges from emergency firefighting activities or firefighting training activities managed in a manner to avoid an instream impact in accordance with § 9.1-207.1 of the Code of Virginia;

b. Fire hydrant flushings, managed in a manner to avoid an instream impact;

c. Potable water, including water line flushings, managed in a manner to avoid an instream impact;

d. Uncontaminated condensate from air conditioners, coolers, and other compressors and from the outside storage of refrigerated gases or liquids;

e. Irrigation drainage;

f. Landscape watering provided all pesticides, herbicides, and fertilizer have been applied in accordance with the approved labeling;

g. Routine external building washdown, provided no soaps, solvents, or detergents are used, external building surfaces do not contain hazardous substances, and the washwater is filtered, settled, or similarly treated prior to discharge;

h. Pavement washwaters, provided no soaps, solvents, detergents, or hazardous cleaning products are used, and no spills or leaks of toxic or hazardous materials have occurred (unless all spilled or leaked material is removed prior to washing), and the washwater is filtered, settled, or similarly treated prior to discharge;

i. Uncontaminated groundwater or spring water;

j. Foundation or footing drains where flows are not contaminated with process materials; and

k. Incidental windblown mist from cooling towers that collects on rooftops or adjacent portions of the facility, but not intentional discharges from the cooling tower (e.g., "piped" cooling tower blowdown or drains).

All other nonstormwater discharges are not authorized and shall either be eliminated or covered under a separate VPDES permit.

2. Releases of hazardous substances or oil in excess of reportable quantities. The discharge of hazardous substances or oil in the stormwater discharges from the facility shall be prevented or minimized in accordance with the SWPPP for the facility. This permit does not authorize the discharge of hazardous substances or oil resulting from an on-site spill. This permit does not relieve the permittee of the reporting requirements of 40 CFR Part 110, 40 CFR Part 117, and 40 CFR Part 302 or § 62.1-44.34:19 of the Code of Virginia.

Where a release containing a hazardous substance or oil in an amount equal to or in excess of a reportable quantity established under either 40 CFR Part 110, 40 CFR Part 117, or 40 CFR Part 302 occurs during a 24-hour period:

a. The permittee is required to notify the department in accordance with the requirements of Part II G as soon as he has knowledge of the discharge;

b. Where a release enters an MS4, the permittee shall also notify the owner of the MS4; and

c. The SWPPP required under Part III shall be reviewed to identify measures to prevent the reoccurrence of the releases and to respond to the releases, and the SWPPP shall be modified where appropriate.

3. Colocated industrial activity. If the facility has industrial activities occurring on-site that are described by any of the activities in Part IV of the permit, those industrial activities are considered to be colocated industrial activities. Stormwater discharges from colocated industrial activities are authorized by this permit, provided that the permittee complies with any and all additional SWPPP and monitoring requirements from Part IV applicable to that particular colocated industrial activity. The permittee shall be responsible for additional SWPPP and monitoring requirements applicable to the colocated industrial activity by examining the narrative descriptions of all discharges covered under this section.

4. The stormwater discharges authorized by this permit may be combined with other sources of stormwater that are not required to be covered under a VPDES permit, so long as the combined discharge is in compliance with this permit.

5. There shall be no discharge of waste, garbage, or floating debris in other than trace amounts.

6. Approval for coverage under this general permit does not relieve the permittee of the responsibility to comply with any other applicable federal, state, or local statute, ordinance, or regulation.

7. Discharges to waters subject to TMDL wasteload allocations. Owners of facilities that are a source of the specified pollutant of concern to waters for which a TMDL wasteload allocation has been approved by EPA before the term of this permit shall incorporate measures and controls into the SWPPP required by Part III that are consistent with the assumptions and requirements of the TMDL. The department will provide written notification to the owner that a facility is subject to the TMDL requirements. The facility's SWPPP shall specifically address any conditions or requirements included in the TMDL that are applicable to discharges from the facility. If the TMDL establishes a specific numeric wasteload allocation that applies to discharges from the facility, the owner shall perform any required monitoring in accordance with Part I A 1 c (3), and implement control measures designed to meet that allocation.

8. Discharges through a regulated MS4 to waters subject to the Chesapeake Bay TMDL. In addition to the requirements of this permit, any facility with industrial activity stormwater discharges through a regulated MS4 that is notified by the MS4 operator that the locality has adopted ordinances to meet the Chesapeake Bay TMDL shall incorporate measures and controls into its SWPPP to comply with applicable local TMDL ordinance requirements.

9. Expansion of facilities that discharge to waters subject to the Chesapeake Bay TMDL. Virginia's Phase I Chesapeake Bay TMDL Watershed Implementation Plan (November 29, 2010), states that the wasteloads from any expansion of an existing permitted facility discharging stormwater in the Chesapeake Bay watershed cannot exceed the nutrient and sediment loadings that were discharged from the expanded portion of the land prior to the land being developed for the expanded industrial activity.

a. For any industrial activity area expansions (i.e., construction activities, including clearing, grading, and excavation activities) that begin on or after July 1, 2024, the permittee shall document in the SWPPP the information and calculations used to determine the nutrient and sediment loadings discharged from the expanded land area before the land was developed, and the measures and controls that were employed to meet the no net increase of stormwater nutrient and sediment load as a result of the expansion of the industrial activity. Any land disturbance that is exempt from permitting under the VPDES construction stormwater general permit regulation (9VAC25-880) is exempt from this requirement.

b. The permittee may use the ~~VSMP~~ water quality design criteria, 9VAC25-875-580, to meet the requirements of Part I B 10 a. Under this criteria, the total phosphorus load shall not exceed the greater of (i) the total phosphorus load that was discharged from the expanded portion of the land before the land being developed for the industrial activity or (ii) 0.41 pounds per acre per year. Compliance with the water quality design criteria may be determined utilizing the Virginia Runoff Reduction Method or another equivalent methodology approved by the department. Design specifications and pollutant removal efficiencies for specific BMPs can be found on the Virginia Stormwater BMP Clearinghouse website.

a. The authorization is made in writing by a person described in Part II K 1;

b. The authorization specifies either an individual or a position having responsibility for the overall operation of the regulated facility or activity (e.g., 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 be a named individual or any individual occupying a named position; and

c. The written authorization is submitted to the department.

3. Changes to authorization. If an authorization under Part II K 2 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 Part II K 2 shall be submitted to the department before or together with any reports, or information to be signed by an authorized representative.

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

L. Duty to comply. The permittee shall comply with all conditions of this permit. Any permit noncompliance constitutes a violation of the State Water Control Law and the Clean Water Act, except that noncompliance with certain provisions of this permit may constitute a violation of the State Water Control Law but not the Clean Water Act. Permit noncompliance is grounds for enforcement action; for permit coverage termination or denial of a permit coverage renewal.

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

M. Duty to reapply. If the permittee wishes to continue an activity regulated by this permit after the expiration date of this permit, the permittee shall submit a new registration statement at least 60 days before the expiration date of the existing permit, unless permission for a later date has been granted by the department. The department shall not grant permission for registration statements to be submitted later than the expiration date of the existing permit.

N. Effect of a permit. This permit neither conveys any property rights in either real or personal property or any exclusive privileges nor authorizes any injury to private property or invasion of personal rights, or any infringement of federal, state, or local law or regulations.

O. State law. Nothing in this permit shall be construed to preclude the institution of any legal action under, or relieve the permittee from any responsibilities, liabilities, or penalties established pursuant to any other state law or regulation or under authority preserved by § 510 of the Clean Water Act. Except as provided in permit conditions on bypassing as described in Part II U and upset as described in Part II V, nothing in this permit shall be construed to relieve the permittee from civil and criminal penalties for noncompliance.

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

U. Bypass.

1. "Bypass" means the intentional diversion of waste streams from any portion of a treatment facility. The 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 Part II U 2 and 3.

2. Notice.

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

b. Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Part II I.

3. Prohibition of bypass.

a. Bypass is prohibited, and the department 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 (e.g., 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 Part II U 2.

b. The department may approve an anticipated bypass, after considering its adverse effects, if the department determines that it will meet the three conditions listed in Part II U 3 a.

V. Upset.

1. An upset constitutes an affirmative defense to an action brought for noncompliance with technology based permit effluent limitations if the requirements of Part II 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. 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 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 Part II I; and

d. The permittee complied with any remedial measures required under Part II S.

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

W. Inspection and entry. 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 on the permittee'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 State Water Control Law, any substances or parameters at any location.

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

X. Permit actions. Permit coverages may be terminated for cause. The filing of a request by the permittee for a permit 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.

2. Coverage under this permit may be automatically transferred to a new permittee if:

a. The current permittee notifies the department within 30 days of the transfer of the title to the facility or property, unless permission for a later date has been granted by the department;

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

c. The department does not notify the existing permittee and the proposed new permittee of its intent to deny the new permittee coverage under the permit. If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in Part II 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.

9VAC25-151-400. Chesapeake Bay total maximum daily load compliance.

A. Chesapeake Bay TMDL Compliance. EPA's Chesapeake Bay TMDL (December 29, 2010) includes wasteload allocations for VPDES permitted industrial stormwater facilities as part of the regulated stormwater aggregate load. EPA used data submitted by Virginia with the Phase I Chesapeake Bay TMDL Watershed Implementation Plan, including the number of industrial stormwater permits per county and the number of urban acres regulated by industrial stormwater permits, as part of their development of the aggregate load. Aggregate loads for industrial stormwater facilities were appropriate because actual facility loading data were not available to develop individual facility wasteload allocations.

Virginia estimated the loadings from industrial stormwater facilities using actual and estimated facility acreage information and total phosphorus (TP) and total nitrogen (TN) loading rates from the Northern Virginia Planning District Commission (NVPDC) Guidebook for Screening Urban Nonpoint Pollution Management Strategies (Annandale, VA November 1979), prepared for the Metropolitan Washington Council of Governments. The loading rates used were as follows:

TP - High (80%) imperviousness industrial; 1.5 lb/ac/yr

TN - High (80%) imperviousness industrial; 12.3 lb/ac/yr

Actual facility area information and TP and TN data collected for facilities subject to Part V of this permit will be used by the department to quantify the nutrient and sediment loads from those VPDES permitted industrial stormwater facilities.

1. Facilities that obtained coverage under the 2019 industrial stormwater general permit that demonstrated compliance with the Chesapeake Bay TMDL loading rates.

Owners shall maintain documentation of their demonstration of compliance with the Chesapeake Bay TMDL loading rates with the SWPPP and shall continue implementing any BMPs that may have been developed as part of that demonstration.

Documentation may include:

a. Calculations submitted to the department indicating that reductions were not necessary;

b. A completed TMDL Action Plan, including a description of the means and methods, such as management practices and retrofit programs that were utilized to meet the required reductions;

c. Other means accepted by the department indicating compliance with the Chesapeake Bay TMDL loading rates.

2. Facilities that obtained coverage under the 2019 industrial stormwater general permit that did not demonstrate compliance with the Chesapeake Bay TMDL loading rates shall submit a demonstration to the department.

a. Owners of facilities that submitted a Chesapeake Bay TMDL action plan during the 2019 industrial stormwater general permit term that did not achieve reductions by the end of the 2019 permit term shall update and resubmit their action plan to the department for approval no later than 60 days following coverage under this general permit. Permittees shall achieve 10% of the remaining reductions by December 31, 2024, and all remaining reductions by December 31, 2025. An annual report shall be submitted to the department by June 30 of each year describing the progress in meeting the interim and final reductions. A final report to demonstrate compliance shall be submitted to the department no later than January 10, 2026. Documentation of compliance with the Chesapeake Bay TMDL loading rates shall be maintained with the SWPPP.

b. Owners of facilities that completed four samples for each outfall for TN and TP during the 2019 industrial stormwater general permit term that did not submit calculations by the end of the 2019 permit term shall utilize the procedures in Part V D to calculate their facility stormwater loads. The permittee shall submit a copy of the calculations, and a Chesapeake Bay TMDL action plan if required under Part V E, no later than 60 days following coverage under this general permit to the DEQ regional office serving the area where the industrial facility is located on a form provided by the department. Reductions, if applicable, shall be achieved by December 31, 2025, and an annual report shall be submitted to the department by June 30 of each year describing the progress in meeting the required reductions until such time that the demonstration is completed. The demonstration shall be submitted to the department no later than January 10, 2026. Documentation of compliance with the Chesapeake Bay TMDL loading rates shall be maintained with the SWPPP.

c. Owners of facilities registered prior to July 1, 2022, that did not complete four samples for each outfall for TN and TP by the end of the 2019 industrial stormwater general permit term shall monitor their discharges for TN and TP to characterize the contributions from their facility's specific industrial sector for these parameters. Total nitrogen is the sum of total Kjeldahl nitrogen (TKN) and nitrite + nitrate and shall be derived from the results of those tests. After the facility is granted coverage under the permit, samples shall be collected during each of the first four quarters of permit coverage. Samples shall be collected and analyzed in accordance with Part V B. Monitoring results shall be reported in accordance with Part V C and Part II C, and retained in accordance with Part II B. Calculations utilizing the procedures in Part V D, and a Chesapeake Bay TMDL action plan if required under Part V E, shall be submitted no later than 60 days following the completion of the fourth quarterly monitoring period to the DEQ regional office serving the area where the industrial facility is located on a form provided by the department. Reductions, if applicable, shall be achieved by December 31, 2025, and an annual report shall be submitted to the department by June 30 of each year describing the progress in meeting the required reductions until such time that the demonstration is completed. The demonstration shall be submitted to the department no later than January 10, 2026. Documentation of compliance with the Chesapeake Bay TMDL loading rates shall be maintained with the SWPPP.

Facilities may use the applicable sampling data collected during the 2019 industrial stormwater general permit term to satisfy all or part of the four monitoring periods requirement in accordance with Part V A 2 c.

d. Owners of facilities registered after June 30, 2022, that did not complete four samples for each outfall for TN and TP by the end of the 2019 industrial stormwater general permit term shall monitor their discharges in accordance with Part V A 3.

3. Facilities that obtain initial coverage under the 2024 industrial stormwater general permit, but are not newly constructed facilities as identified in 9VAC25-151-60 C 13.

Owners of facilities in the Chesapeake Bay watershed that obtain initial coverage under the 2024 industrial stormwater general permit shall monitor their discharges for TN and TP to characterize the contributions from their facility's specific industrial sector for these parameters. Total nitrogen is the sum of total Kjeldahl nitrogen (TKN) and nitrite + nitrate and shall be derived from the results of those tests. After the facility is granted coverage under the permit, samples shall be collected during each of the first four quarters of permit coverage. Samples shall be collected and analyzed in accordance with Part V B. Monitoring results shall be reported in accordance with Part V C and Part II C, and retained in accordance with Part II B. Calculations utilizing the procedures in Part V D and a Chesapeake Bay TMDL action plan if required under Part V E shall be submitted no later than 60 days following the completion of the fourth quarterly monitoring period to the DEQ regional office serving the area where the industrial facility is located on a form provided by the department. Reductions, if applicable, shall be achieved by two years following the end of the fourth quarterly monitoring period, and an annual report shall be submitted to the department by June 30 of each year describing the progress in meeting the required reductions until such time that the demonstration is completed. The demonstration shall be submitted to the department no later than the 10th of the month directly following the two year period. Documentation of compliance with the Chesapeake Bay TMDL loading rates shall be maintained with the SWPPP.

B. Monitoring instructions.

1. Collection and analysis of samples. Sampling requirements shall be assessed on an outfall by outfall basis. Samples shall be collected and analyzed in accordance with the requirements of Part II A.

2. When and how to sample. A minimum of one grab sample shall be taken from the discharge associated with industrial activity resulting from a storm event that results in a discharge from the site providing the interval from the preceding storm event discharge is at least 72 hours. The 72-hour storm interval is waived if the permittee is able to document that less than a 72-hour interval is representative for local storm events during the sampling period. In the case of snowmelt, the monitoring shall be performed at a time when a measurable discharge occurs at the site. For discharges from a stormwater management structure, the monitoring shall be performed at a time when a measurable discharge occurs from the structure.

The grab sample shall be taken during the first 30 minutes of the discharge. If it is not practicable to take the sample during the first 30 minutes, the sample may be taken during the first three hours of the discharge, provided that the permittee explains why a grab sample during the first 30 minutes was impracticable. This information shall be submitted in the department's electronic discharge monitoring report (e-DMR) system and maintained with the SWPPP. If the sampled discharge commingles with process or nonprocess water, the permittee shall attempt to sample the stormwater discharge before it mixes with the nonstormwater.

3. Storm event data. For each monitoring event, except snowmelt monitoring, along with the monitoring results, the permittee shall identify the date of the storm event sampled; rainfall total (in inches) of the storm event that generated the sampled runoff; and the interval between the storm event sampled and the end of the previous storm event discharge. For snowmelt monitoring, the permittee shall identify the date of the sampling event.

4. Monitoring periods. Quarterly monitoring shall be conducted in each of the following three-month periods: January through March, April through June, July through September, and October through December.

5. Documentation explaining a facility's inability to obtain a sample (including dates and times the outfalls were viewed or sampling was attempted), of no rain event, or of deviation from the 72-hour storm interval shall be submitted with the e-DMR and maintained with the SWPPP. Acceptable documentation includes National Climatic Data Center (NCDC) weather station data, local weather station data, facility rainfall logs, and other appropriate supporting data.

6. Representative outfalls may be used in accordance with Part I A 2 f.

C. Reporting monitoring results.

1. Reporting to the department. The permittee shall follow the reporting requirements and deadlines in Table 400-1 if required by Part V A 2 or A 3:

Table 400-1

Monitoring Reporting Requirements

Quarterly Chesapeake Bay TMDL Monitoring

Submit the results by January 10, April 10, July 10, and October 10

2. Permittees shall submit results for each outfall associated with industrial activity according to the requirements of Part II C.

3. Significant digits. The permittee shall report at least the same number of significant digits as a numeric effluent limitation or TMDL wasteload allocation for a given parameter; otherwise, at least two significant digits shall be reported for a given parameter. Regardless of the rounding convention used by the permittee (i.e., five always rounding up or to the nearest even number), the permittee shall use the convention consistently and shall ensure that consulting laboratories employed by the permittee use the same convention.

D. Calculation of facility loads.

Permittees required to collect nutrient and sediment data in accordance with Part V A 2 or A 3 shall analyze the data collected to determine if pollution reductions are required. The permittee shall average the data collected at the facility for each of the pollutants of concern (POC) (e.g., TP and TN) and compare the results to the loading rates for TP and TN presented in Part V A.

The following formula may be used to determine the loading rate:

L = 0.226 x P x Pj x (0.05 + (0.9 x Ia)) x C

where:

L = the POC loading rate (lb/acre/year)

P = the annual rainfall (inches/year) - The permittee may use either actual annual average rainfall data for the facility location (in inches/year), the Virginia annual average rainfall of 44.3 inches/year, or another method approved by the department.

Pj = the fraction of annual events that produce runoff - The permittee shall use 0.9 unless the department approves another rate.

Ia = the impervious fraction of the facility impervious area of industrial activity to the facility industrial activity area.

C = the POC average concentration of all facility samples (mg/L) - Facilities with multiple outfalls shall calculate a weighted average concentration for each outfall using the drainage area of each outfall.

For total phosphorus, all daily concentration data below the quantitation level (QL) for the analytical method used shall be treated as half the QL. All daily concentration data equal to or above the QL for the analytical method used shall be treated as it is reported.

For total nitrogen, if none of the daily concentration data for the respective species (i.e., TKN, nitrate, or nitrite) are equal to or above the QL for the respective analytical methods used, the daily TN concentration value reported shall equal one half of the largest QL used for the respective species. If one of the data is equal to or above the QL, the daily TN concentration value shall be treated as that data point is reported. If more than one of the data is above the QL, the daily TN concentration value shall equal the sum of the data points as reported.

Calculations shall be submitted to the department within 60 days from the end of the last monitoring period that satisfies the monitoring requirements in Part V A 2 or A 3. Calculations shall be submitted to the DEQ regional office serving the area where the industrial facility is located, on a form provided by the department, and maintained with the facility's SWPPP.

Alternative calculations may be accepted on a case by case basis by the department to accommodate facilities with outfalls that rarely discharge.

E. Chesapeake Bay TMDL action plan requirements. For permittees required to submit calculations in accordance with Part V D, if the calculated facility loading rate for TP or TN is above the loading rates for TP or TN presented in Part V A, then the permittee shall develop and submit a Chesapeake Bay TMDL action plan to the department.

The Chesapeake Bay TMDL action plan shall be submitted on a form provided by the department to the regional office serving the area where the industrial facility is located within 60 days following the completion of the fourth quarterly monitoring period. A copy of the current Chesapeake Bay TMDL action plan and all facility loading rate calculations shall be maintained with the facility's SWPPP. The Chesapeake Bay TMDL action plan shall include:

1. A determination of the total pollutant load reductions for TP and TN (as appropriate) necessary to reduce the annual loads from industrial activities. This shall be determined by multiplying the industrial average times the difference between the TMDL loading rates listed in Part V A and the actual facility loading rates calculated in accordance with Part V D. The reduction applies to the total difference calculated for each pollutant of concern; and

2. The means and methods, such as management practices and retrofit programs that will be utilized to meet the required reductions determined in Part V E 1 and a schedule to achieve those reductions by the applicable deadline set in Part V A 2 or A 3. Pollutant reductions may be achieved using a combination of the following alternatives:

a. Reductions provided by one or more of the BMPs from the Virginia Stormwater BMP Clearinghouse listed in ~~9VAC25-870-65~~ 9VAC25-875-590, approved BMPs found on the Virginia Stormwater Clearinghouse website, or BMPs approved by the Chesapeake Bay Program. Any BMPs implemented to provide the required pollutant reductions shall be incorporated in the SWPPP and be permanently maintained by the permittee;

b. Implementation of site-specific BMPs followed by a minimum of four stormwater samples collected in accordance with sampling requirements in Part V B that demonstrate pollutant loadings have been reduced below those calculated under Part V D. Any BMPs implemented to provide the required pollutant reductions shall be incorporated in the SWPPP and be permanently maintained by the permittee; or

c. Acquisition of nonpoint source credits certified by the board as perpetual in accordance with § 62.1-44.19:20 of the Code of Virginia.

9VAC25-210-60. Exclusions.

The activities in this section do not require a VWP permit but may require other permits under state and federal law. Upon request by the department, any person claiming one of these exclusions shall demonstrate to the satisfaction of the department that he qualifies for the exclusion. Exclusions pertaining to surface water withdrawals are established in 9VAC25-210-310.

1. Discharges of dredged or fill material into state waters, except wetlands, which are addressed under a USACE Regional, General, or Nationwide Permit, and for which no § 401 Water Quality Certificate is required.

2. Any discharge of stormwater from municipal separate storm sewer systems or ~~land disturbing~~ land-disturbing activities authorized by ~~9VAC25-870~~ 9VAC25-875, or the discharge of sewage, industrial wastes, or other wastes or any noxious or deleterious substances into surface waters that is authorized by a Virginia Pollutant Discharge Elimination System (VPDES) permit in accordance with 9VAC25-31 or a Virginia Pollution Abatement (VPA) permit in accordance with 9VAC25-32.

3. Any activity governed under Chapter 13 (§ 28.2-1300 et seq.) of Title 28.2 of the Code of Virginia, unless state certification is required by § 401 of the Clean Water Act. State certification is waived if the activity meets the provisions of subdivision 10 a of this section. The activity does not require a VWP permit pursuant to § 62.1-44.15:21 G of the Code of Virginia.

4. Normal residential gardening and lawn and landscape maintenance in a wetland, or other similar activity, that is incidental to an occupant's ongoing residential use of property and is of minimal ecological impact. The criteria governing this exclusion are set forth in the definition of "normal residential gardening and lawn and landscape maintenance" in 9VAC25-210-10.

5. Maintenance of currently serviceable structures, such as purpose-built stormwater and utility structures, transportation structures, dikes, groins, levees, dams, riprap breakwaters, causeways, or bridge abutments or approaches. Maintenance includes the emergency reconstruction of recently damaged parts but does not include modifications that change the character, scope, or size of the original design. If the original design is not available, the permittee shall submit the best available information on the design for consideration and approval by the department. In order to quality for this exclusion, emergency reconstruction shall occur as soon as practicable after damage occurs.

6. Impacts to open waters that do not have a detrimental effect on public health, animal life, or aquatic life or to the uses of such waters for domestic or industrial consumption, recreation, or other uses.

7. Flooding or back-flooding impacts to surface waters resulting from the construction of temporary sedimentation basins on a construction site when such structures are necessary for erosion and sediment control or stormwater management purposes.

8. Normal agriculture and silviculture activities in a wetland such as plowing; seeding; cultivating; minor drainage and harvesting for the production of food, fiber, and forest products; or upland soil and water conservation practices.

a. To fall under this exclusion, the activities specified in this subdivision 8 must be part of an established (i.e., ongoing) agriculture or silviculture operation, and must be in accordance with applicable best management practices set forth in either Forestry Best Management Practices for Water Quality in Virginia Technical Guide (Fourth Edition, July 2002) or Virginia Agricultural BMP Manual (2000), which facilitate compliance with the § 404(b)(1) Guidelines (40 CFR Part 230). Activities on areas lying fallow as part of a conventional, rotational cycle are part of an established operation.

b. Activities which bring a new area into agricultural or silvicultural use are not part of an established operation. An operation ceases to be established when the area in which it was conducted has been converted to another use or has lain idle so long that modifications to the hydrological regime are necessary to resume operation. If the activity takes place outside surface waters, it does not need a VWP permit, whether or not it is part of an established agriculture or silviculture operation.

c. For the purposes of this subdivision 8, cultivating, harvesting, minor drainage, plowing, and seeding are defined as follows:

(1) "Cultivating" means physical methods of soil treatment employed within established agriculture and silviculture lands on farm or forest crops to aid and improve their growth, quality, or yield.

(2) "Harvesting" means physical measures employed directly upon farm, forest, or crops within established agricultural and silviculture lands to bring about their removal from farm or forest land, but does not include the construction of farm or forest roads.

(3) "Minor drainage" means:

(a) The discharge of dredged or fill material incidental to connecting upland drainage facilities to surface waters, adequate to effect the removal of excess soil moisture from upland croplands. Construction and maintenance of upland (dryland) facilities, such as ditching and tiling, incidental to the planting, cultivating, protecting, or harvesting of crops;

(b) The discharge of dredged or fill material for the purpose of installing ditching or other water control facilities incidental to planting, cultivating, protecting, or harvesting of rice, or other wetland crop species, where these activities and the discharge occur in surface waters which are in established use for such agricultural and silviculture wetland crop production;

(c) The discharge of dredged or fill material for the purpose of manipulating the water levels of, or regulating the flow or distribution of water within, existing impoundments that have been constructed in accordance with applicable requirements of the Clean Water Act, and that are in established use for the production of rice, or other wetland crop species;

(d) The discharge of dredged or fill material incidental to the emergency removal of sandbars, gravel bars, or other similar blockages which are formed during flood flows or other events, where such blockages close or constrict previously existing drainageways and, if not promptly removed, would result in damage to or loss of existing crops or would impair or prevent the plowing, seeding, harvesting, or cultivating of crops on land in established use for crop production. Such removal does not include enlarging or extending the dimensions of, or changing the bottom elevations of, the affected drainageway as it existed prior to the formation of the blockage. Removal must be accomplished within one year after such blockages are discovered in order to be eligible for exclusion; and

(e) Minor drainage in surface waters is limited to drainage within areas that are part of an established agriculture or silviculture operation. It does not include drainage associated with the immediate or gradual conversion of a wetland to a nonwetland (for example, wetland species to upland species not typically adapted to life in saturated soil conditions), or conversion from one wetland use to another (for example, silviculture to agriculture). In addition, minor drainage does not include the construction of any canal, ditch, dike, or other waterway or structure which drains or otherwise significantly modifies a stream, lake, swamp, bog, or any other wetland or aquatic area constituting surface water. Any discharge of dredged or fill material into surface water incidental to the construction of any such structure or waterway requires a VWP permit, unless otherwise excluded or exempted by this chapter.

(4) "Plowing" means all forms of primary tillage, including moldboard, chisel, or wide-blade plowing, discing, harrowing, and similar physical means used on farm or forest land for the breaking up, cutting, turning over, or stirring of soil to prepare it for the planting of crops. Plowing does not include the redistribution of soil, rock, sand, or other surficial materials in a manner which changes any area of surface water to dry land. For example, the redistribution of surface materials by blading, grading, or other means to fill in wetland areas is not plowing. Rock crushing activities which result in the loss of natural drainage characteristics, the reduction of water storage and recharge capabilities, or the overburden of natural water filtration capacities does not constitute plowing. Plowing as described above will never involve a discharge of dredged or fill material.

(5) "Seeding" means the sowing of seed and placement of seedlings to produce farm or forest crops and includes the placement of soil beds for seeds or seedlings on established farm and forest lands.

9. Discharges of dredged or fill material into wetlands when addressed under a U.S. Army Corps of Engineers Regional, General, or Nationwide Permit and that meet the provisions of subdivision 10 a of this section.

10. Construction or maintenance of farm ponds or impoundments, stock ponds or impoundments, or irrigation ditches, or the maintenance (but not construction) of drainage ditches.

a. The exclusion for the construction and maintenance of farm or stock ponds and farm or stock impoundments applies to those structures that are operated for normal agricultural or silvicultural purposes, and are less than 25 feet in height or create a maximum impoundment capacity smaller than 100 acre-feet.

b. The exclusion for the construction and maintenance of farm or stock ponds and farm or stock impoundments does not include the impacts associated with the withdrawal of surface water from, within, or behind such structures. A VWP permit may be required for the surface water withdrawal.

c. Discharge associated with siphons, pumps, headgates, wingwalls, weirs, diversion structures, and such other facilities as are appurtenant and functionally related to irrigation ditches are included in this exclusion.

d. The maintenance dredging of existing ditches is included in this exclusion provided that the final dimensions of the maintained ditch do not exceed the average dimensions of the original ditch. This exclusion does not apply to the construction of new ditches or to the channelization of streams.

11. Construction or maintenance of farm roads, forest roads, or temporary roads for moving mining equipment, where such roads are constructed and maintained in accordance with applicable best management practices (BMPs) set forth in either Forestry Best Management Practices for Water Quality in Virginia, Technical Guide, Fourth Edition, July 2002, or Virginia Agricultural BMP Manual, 2000, to ensure that flow and circulation patterns and chemical and biological characteristics of surface waters are not impaired, that the reach of such waters is not reduced, and that any adverse effect on the aquatic environment will otherwise be minimized. The BMPs which must be applied to satisfy this provision include the following baseline provisions:

a. Permanent roads (for agriculture or forestry activities), temporary access roads (for mining, forestry, or farm purposes), and skid trails (for logging) in surface waters shall be held to the minimum feasible number, width, and total length consistent with the purpose of specific agriculture, silviculture or mining operations, and local topographic and climatic conditions;

b. All roads, temporary or permanent, shall be located sufficiently far from streams or other water bodies (except for portions of such roads which must cross water bodies) to minimize discharges of dredged or fill material into surface waters;

c. The road fill shall be bridged, piped, culverted, or otherwise designed to prevent the restriction of expected flood flows;

d. The fill shall be properly stabilized and maintained to prevent erosion during and following construction;

e. Discharges of dredged or fill material into surface waters to construct road fill shall be made in a manner which minimizes the encroachment of trucks, tractors, bulldozers, or other heavy equipment within state waters (including adjacent wetlands) that lie outside the lateral boundaries of the fill itself;

f. In designing, constructing, and maintaining roads, vegetative disturbance in surface waters shall be kept to a minimum;

g. The design, construction, and maintenance of the road crossing shall not disrupt the migration or other movement of those species of aquatic life inhabiting the water body;

h. Borrow material shall be taken from upland sources whenever feasible;

i. The discharge shall not take, or jeopardize the continued existence of a state-listed or federally-listed threatened or endangered species as defined under the Endangered Species Act (16 USC § 1531 et seq.), in § 29.1-566 of the Code of Virginia and in 4VAC15-20-130 B and C, except as provided in § 29.1-568 of the Code of Virginia, or adversely modify or destroy the critical habitat of such species;

j. Discharges into the nesting and breeding areas for migratory waterfowl, spawning areas, and wetlands shall be avoided if practical on-site or off-site alternatives exist;

k. The discharge shall not be located in proximity of a public water supply or intake;

l. The discharge shall not occur in areas of concentrated shellfish production;

m. The discharge shall not occur in a component to the National Wild and Scenic River System;

n. The discharge material shall consist of suitable material free from toxic pollutants in toxic amounts; and

o. All temporary fills shall be removed in their entirety and the area restored to its original elevation.

12. Wetland and open water impacts to a stormwater management facility that was created on dry land for the purpose of conveying, treating, or storing stormwater.

9VAC25-830-130. General performance criteria.

Through their applicable land use ordinances, regulations, and enforcement mechanisms, local governments shall require that any use, development, or redevelopment of land in Chesapeake Bay Preservation Areas meets the following performance criteria:

1. No more land shall be disturbed than is necessary to provide for the proposed use or development.

2. Indigenous vegetation shall be preserved to the maximum extent practicable, consistent with the use or development proposed. Mature trees shall be protected during development and only removed where necessary, including to provide for the proposed use or development.

A locality which has an ordinance providing for the conservation, planting, and replacement of trees during the land development process pursuant to § 15.2-961 or 15.2-961.1 of the Code of Virginia may rely on such ordinance for demonstrating compliance with this requirement related to mature trees in Resource Management Areas.

3. All development exceeding 2,500 square feet of land disturbance shall be accomplished through a plan of development review process consistent with § 15.2-2286 A 8 of the Code of Virginia and subdivision 1 e of 9VAC25-830-240.

4. Land development shall minimize impervious cover consistent with the proposed use or development.

5. Any ~~land disturbing~~ land-disturbing activity that exceeds an area of 2,500 square feet (including construction of all single family houses, septic tanks, and drainfields, but otherwise as defined in § 62.1-44.15:24 or 62.1-44.15:51 of the Code of Virginia) shall comply with the requirements of the local erosion and sediment control program ordinance or erosion and stormwater management program ordinance. Enforcement for noncompliance with the erosion and sediment control requirements referenced in this criterion shall be conducted under the provisions of the ~~Erosion and Sediment~~ State Water Control Law (§ 62.1-44.2 et seq. of the Code of Virginia) and attendant regulations.

6. ~~Any~~ Land-disturbing activities in a Chesapeake Bay Preservation ~~Act land-disturbing activity as defined in § 62.1-44.15:24 of the Code of Virginia~~ Area that are equal to or greater than 2,500 square feet but less than one acre shall comply with the requirements of ~~9VAC25-870-51~~ 9VAC25-875-740 and ~~9VAC25-870-103~~ 9VAC25-875-750.

7. Onsite sewage treatment systems not requiring a Virginia Pollutant Discharge Elimination System (VPDES) permit shall:

a. Have pump-out accomplished for all such systems at least once every five years.

(1) If deemed appropriate by the local health department and subject to conditions the local health department may set, local governments may offer to the owners of such systems, as an alternative to the mandatory pump-out, the option of having a plastic filter installed and maintained in the outflow pipe from the septic tank to filter solid material from the effluent while sustaining adequate flow to the drainfield to permit normal use of the septic system. Such a filter should satisfy standards established in the Sewage Handling and Disposal Regulations (12VAC5-610) administered by the Virginia Department of Health.

(2) Furthermore, in lieu of requiring proof of septic tank pump-out every five years, local governments may allow owners of onsite sewage treatment systems to submit documentation every five years, certified by an operator or onsite soil evaluator licensed or certified under Chapter 23 (§ 54.1-2300 et seq.) of Title 54.1 of the Code of Virginia as being qualified to operate, maintain, or design onsite sewage systems, that the septic system has been inspected, is functioning properly, and the tank does not need to have the effluent pumped out of it.

(3) Effective July 1, 2023, requirements of this section directly related to compliance with onsite sewage system pump-outs shall be managed and enforced by the Virginia Department of Health in Accomack, Essex, Gloucester, King and Queen, King William, Lancaster, Mathews, Middlesex, Northampton, Northumberland, Richmond, and Westmoreland Counties, and the incorporated towns within those counties.

b. For new construction, provide a reserve sewage disposal site with a capacity at least equal to that of the primary sewage disposal site. This reserve sewage disposal site requirement shall not apply to any lot or parcel recorded prior to October 1, 1989, if the lot or parcel is not sufficient in capacity to accommodate a reserve sewage disposal site, as determined by the local health department. Building shall be prohibited on the area of all sewage disposal sites until the structure is served by public sewer or an onsite sewage treatment system that operates under a permit issued by the department. All sewage disposal site records shall be administered to provide adequate notice and enforcement. As an alternative to the 100% reserve sewage disposal site, local governments may offer the owners of such systems the option of installing an alternating drainfield system meeting the following conditions:

(1) Each of the two alternating drainfields in the system shall have, at a minimum, an area not less than 50% of the area that would otherwise be required if a single primary drainfield were constructed.

(2) An area equaling 50% of the area that would otherwise be required for the primary drainfield site must be reserved for subsurface absorption systems that utilize a flow diversion device, in order to provide for future replacement or repair to meet the requirements for a sewage disposal system. Expansion of the primary system will require an expansion of this reserve area.

(3) The two alternating drainfields shall be connected by a diversion valve, approved by the local health department, located in the pipe between the septic (aerobic) tank and the distribution boxes. The diversion valve shall be used to alternate the direction of effluent flow to one drainfield or the other at a time. However, diversion valves shall not be used for the following types of treatment systems:

(a) Sand mounds;

(b) Low-pressure distribution systems;

(d) Any other approved system for which the use of a valve would adversely affect the design of the system, as determined by the local health department.

(4) The diversion valve shall be a three-port, two-way valve of approved materials (i.e., resistant to sewage and leakproof and designed so that the effluent from the tank can be directed to flow into either one of the two distribution boxes).

(5) There shall be a conduit from the top of the valve to the ground surface with an appropriate cover to be level with or above the ground surface.

(6) The valve shall not be located in driveways, recreational courts, parking lots, or beneath sheds or other structures.

(7) In lieu of the aforementioned diversion valve, any device that can be designed and constructed to conveniently direct the flow of effluent from the tank into either one of the two distribution boxes may be approved if plans are submitted to the local health department and found to be satisfactory.

(8) The local government shall require that the owner alternate the drainfields every 12 months to permit the yearly resting of half of the absorption system.

(9) The local government shall ensure that the owner are notified annually of the requirement to switch the valve to the opposite drainfield.

8. Land upon which agricultural activities are being conducted, including crop production, pasture, and dairy and feedlot operations, or lands otherwise defined as agricultural land by the local government, shall have a soil and water quality conservation assessment conducted that evaluates the effectiveness of existing practices pertaining to soil erosion and sediment control, nutrient management, and management of pesticides, and, where necessary, results in a plan that outlines additional practices needed to ensure that water quality protection is being accomplished consistent with the Act and this chapter.

a. Recommendations for additional conservation practices need address only those conservation issues applicable to the tract or field being assessed. Any soil and water quality conservation practices that are recommended as a result of such an assessment and are subsequently implemented with financial assistance from federal or state cost-share programs must be designed, consistent with cost-share practice standards effective in January 1999 in the "Field Office Technical Guide" of the U.S. Department of Agriculture Natural Resource Conservation Service or the June 2000 edition of the "Virginia Agricultural BMP Manual" of the Virginia Department of Conservation and Recreation, respectively. Unless otherwise specified in this section, general standards pertaining to the various agricultural conservation practices being assessed shall be as follows:

(1) For erosion and sediment control recommendations, the goal shall be, where feasible, to prevent erosion from exceeding the soil loss tolerance level, referred to as "T," as defined in the "National Soil Survey Handbook" of November 1996 in the "Field Office Technical Guide" of the U.S. Department of Agriculture Natural Resource Conservation Service. However, in no case shall erosion exceed the soil loss consistent with an Alternative Conservation System, referred to as an "ACS", as defined in the "Field Office Technical Guide" of the U.S. Department of Agriculture Natural Resource Conservation Service.

(2) For nutrient management, whenever nutrient management plans are developed, the operator or landowner must provide soil test information, consistent with the Virginia Nutrient Management Training and Certification Regulations (4VAC50-85).

(3) For pest chemical control, referrals shall be made to the local cooperative extension agent or an Integrated Pest Management Specialist of the Virginia Cooperative Extension Service. Recommendations shall include copies of applicable information from the "Virginia Pest Management Guide" or other Extension materials related to pest control.

b. A higher priority shall be placed on conducting assessments of agricultural fields and tracts adjacent to Resource Protection Areas. However, if the landowner or operator of such a tract also has Resource Management Area fields or tracts in his operation, the assessment for that landowner or operator may be conducted for all fields or tracts in the operation. When such an expanded assessment is completed, priority must return to Resource Protection Area fields and tracts.

c. The findings and recommendations of such assessments and any resulting soil and water quality conservation plans will be submitted to the local Soil and Water Conservation District Board, which will be the plan-approving authority.

9. Silvicultural activities in Chesapeake Bay Preservation Areas are exempt from this chapter provided that silvicultural operations adhere to water quality protection procedures prescribed by the Virginia Department of Forestry in the Fifth Edition (March 2011) of "Virginia's Forestry Best Management Practices for Water Quality Technical Manual." The Virginia Department of Forestry will oversee and document installation of best management practices and will monitor in-stream impacts of forestry operations in Chesapeake Bay Preservation Areas.

10. Local governments shall require evidence of all wetlands permits required by law prior to authorizing grading or other onsite activities to begin.

(4) Access to the water-dependent facility will be provided with the minimum disturbance necessary. Where practicable, a single point of access will be provided.

c. Redevelopment outside locally designated Intensely Developed Areas shall be permitted in the Resource Protection Area only if there is no increase in the amount of impervious cover and no further encroachment within the Resource Protection Area, and it shall conform to applicable erosion and sediment control and stormwater management criteria set forth in the Erosion and Sediment Control Law for Localities Not Administering a Virginia Erosion and Stormwater Management Program and the Virginia Erosion and Stormwater Management Act and their attendant regulations, as well as all applicable stormwater management requirements of other state and federal agencies.

d. Roads and driveways not exempt under subdivision B 1 of 9VAC25-830-150 and which, therefore, must comply with the provisions of this chapter, may be constructed in or across Resource Protection Areas if each of the following conditions is met:

(1) The local government makes a finding that there are no reasonable alternatives to aligning the road or driveway in or across the Resource Protection Area;

(2) The alignment and design of the road or driveway are optimized, consistent with other applicable requirements, to minimize (i) encroachment in the Resource Protection Area and (ii) adverse effects on water quality;

(3) The design and construction of the road or driveway satisfy all applicable criteria of this chapter, including submission of a water quality impact assessment; and

(4) The local government reviews the plan for the road or driveway proposed in or across the Resource Protection Area in coordination with local government site plan, subdivision and plan of development approvals.

e. Flood control and stormwater management facilities that drain or treat water from multiple development projects or from a significant portion of a watershed may be allowed in Resource Protection Areas provided such facilities are allowed and constructed in accordance with the Virginia Erosion and Stormwater Management Act and its attendant regulations, and provided that (i) the local government has conclusively established that location of the facility within the Resource Protection Area is the optimum location; (ii) the size of the facility is the minimum necessary to provide necessary flood control or stormwater treatment, or both; (iii) the facility must be consistent with a comprehensive stormwater management plan developed and approved in accordance with ~~9VAC25-870-92~~ 9VAC25-875-660 ~~of the Virginia Stormwater Management Program (VSMP) regulations~~; (iv) all applicable permits for construction in state or federal waters must be obtained from the appropriate state and federal agencies, such as the U.S. Army Corps of Engineers, the department, and the Virginia Marine Resources Commission; (v) approval must be received from the local government prior to construction; and (vi) routine maintenance is allowed to be performed on such facilities to assure that they continue to function as designed. It is not the intent of this subdivision to allow a best management practice that collects and treats runoff from only an individual lot or some portion of the lot to be located within a Resource Protection Area.

2. Exemptions in Resource Protection Areas. The following land disturbances in Resource Protection Areas may be exempt from the criteria of this part provided that they comply with subdivisions a and b of this subdivision 2: (i) water wells; (ii) passive recreation facilities such as boardwalks, trails, and pathways; and (iii) historic preservation and archaeological activities:

a. Local governments shall establish administrative procedures to review such exemptions.

b. Any land disturbance exceeding an area of 2,500 square feet shall comply with the erosion and sediment control criteria in subdivision 5 of 9VAC25-830-130.

3. Buffer area requirements. The 100-foot wide buffer area shall be the landward component of the Resource Protection Area as set forth in subdivision B 5 of 9VAC25-830-80. Notwithstanding permitted uses, encroachments, and vegetation clearing, as set forth in this section, the 100-foot wide buffer area is not reduced in width. To minimize the adverse effects of human activities on the other components of the Resource Protection Area, state waters, and aquatic life, a 100-foot wide buffer area of vegetation that is effective in retarding runoff, preventing erosion, and filtering nonpoint source pollution from runoff shall be retained if present and established where it does not exist. Where such buffer must be established, the planting of trees shall be incorporated as appropriate to site conditions and in such a manner to maximize the buffer function. Inclusion of native species in tree planting is preferred.

a. The 100-foot wide buffer area shall be deemed to achieve a 75% reduction of sediments and a 40% reduction of nutrients.

b. Where land uses such as agriculture or silviculture within the area of the buffer cease and the lands are proposed to be converted to other uses, the full 100-foot wide buffer shall be reestablished. In reestablishing the buffer, management measures shall be undertaken to provide woody vegetation that assures the buffer functions set forth in this chapter. Where such buffer must be reestablished, the planting of trees shall be incorporated as appropriate to site conditions and in such a manner to maximize the buffer function. Inclusion of native species in tree planting is preferred.

4. Permitted encroachments into the buffer area.

a. When the application of the buffer area would result in the loss of a buildable area on a lot or parcel recorded prior to October 1, 1989, encroachments into the buffer area may be allowed through an administrative process in accordance with the following criteria:

(1) Encroachments into the buffer area shall be the minimum necessary to achieve a reasonable buildable area for a principal structure and necessary utilities.

(2) Where practicable, a vegetated area that will maximize water quality protection, mitigate the effects of the buffer encroachment, and is equal to the area of encroachment into the buffer area shall be established elsewhere on the lot or parcel. Such vegetated area where established shall include the planting of trees as appropriate to site conditions. Inclusion of native species in tree planting is preferred.

(3) The encroachment may not extend into the seaward 50 feet of the buffer area.

b. When the application of the buffer area would result in the loss of a buildable area on a lot or parcel recorded between October 1, 1989, and March 1, 2002, encroachments into the buffer area may be allowed through an administrative process in accordance with the following criteria:

(1) The lot or parcel was created as a result of a legal process conducted in conformity with the local government's subdivision regulations;

(2) Conditions or mitigation measures imposed through a previously approved exception shall be met;

(3) If the use of a best management practice (BMP) was previously required, the BMP shall be evaluated to determine if it continues to function effectively and, if necessary, the BMP shall be reestablished or repaired and maintained as required; and

(4) The criteria in subdivision 4 a of this section shall be met.

5. Permitted modifications of the buffer area.

a. In order to maintain the functional value of the buffer area, existing vegetation may be removed, subject to approval by the local government, only to provide for reasonable sight lines, access paths, general woodlot management, and best management practices, including those that prevent upland erosion and concentrated flows of stormwater, as follows:

(1) Trees may be pruned or removed as necessary to provide for sight lines and vistas, provided that where removed, they shall be replaced with other vegetation that is equally effective in retarding runoff, preventing erosion, and filtering nonpoint source pollution from runoff. Mature trees shall be preserved and trimmed or pruned in lieu of removal as site conditions permit and any removal should be limited to the fewest number of trees feasible. When trees are removed to provide for sight lines and vista, they shall be replaced with trees as appropriate to site conditions and in such a manner as to maximize the buffer function and to protect the quality of state waters. Inclusion of native species in tree replanting is preferred.

(2) Any path shall be constructed and surfaced so as to effectively control erosion.

(3) Dead, diseased, or dying trees or shrubbery and noxious weeds (such as Johnson grass, kudzu, and multiflora rose) may be removed and thinning of trees may be allowed pursuant to sound horticultural practice incorporated into locally-adopted standards.

(4) For shoreline erosion control projects, trees and woody vegetation may be removed, necessary control techniques employed, and appropriate vegetation established to protect or stabilize the shoreline in accordance with the best available technical advice and applicable permit conditions or requirements. Mature trees shall be removed only as necessary for the installation and maintenance of the projects consistent with the best available technical advice project plans, and applicable permit conditions or requirements. Trees shall be utilized in the project when vegetation is being established as appropriate to the site conditions and the project specifications. Inclusion of native species in tree planting is preferred.

b. On agricultural lands the agricultural buffer area shall be managed to prevent concentrated flows of surface water from breaching the buffer area and appropriate measures may be taken to prevent noxious weeds (such as Johnson grass, kudzu, and multiflora rose) from invading the buffer area. Agricultural activities may encroach into the buffer area as follows:

(1) Agricultural activities may encroach into the landward 50 feet of the 100-foot wide buffer area when at least one agricultural best management practice which, in the opinion of the local soil and water conservation district board, addresses the more predominant water quality issue on the adjacent land—erosion control or nutrient management—is being implemented on the adjacent land, provided that the combination of the undisturbed buffer area and the best management practice achieves water quality protection, pollutant removal, and water resource conservation at least the equivalent of the 100-foot wide buffer area. If nutrient management is identified as the predominant water quality issue, a nutrient management plan, including soil tests, must be developed consistent with the Nutrient Management Training and Certification Regulations (4VAC50-85) administered by the Virginia Soil and Water Conservation Board.

(2) Agricultural activities may encroach within the landward 75 feet of the 100-foot wide buffer area when agricultural best management practices which address erosion control, nutrient management, and pest chemical control, are being implemented on the adjacent land. The erosion control practices must prevent erosion from exceeding the soil loss tolerance level, referred to as "T," as defined in the "National Soil Survey Handbook" of November 1996 in the "Field Office Technical Guide" of the U.S. Department of Agriculture Natural Resource Conservation Service. A nutrient management plan, including soil tests, must be developed, consistent with the Nutrient Management Training and Certification Regulations (4VAC50-85) administered by the Virginia Soil and Water Conservation Board. In conjunction with the remaining buffer area, this collection of best management practices shall be presumed to achieve water quality protection at least the equivalent of that provided by the 100-foot wide buffer area.

(3) The buffer area is not required to be designated adjacent to agricultural drainage ditches if at least one best management practice which, in the opinion of the local soil and water conservation district board, addresses the more predominant water quality issue on the adjacent land—either erosion control or nutrient management—is being implemented on the adjacent land.

(4) If specific problems are identified pertaining to agricultural activities that are causing pollution of the nearby water body with perennial flow or violate performance standards pertaining to the vegetated buffer area, the local government, in cooperation with soil and water conservation district, shall recommend a compliance schedule to the landowner and require the problems to be corrected consistent with that schedule. This schedule shall expedite environmental protection while taking into account the seasons and other temporal considerations so that the probability for successfully implementing the corrective measures is greatest.

(5) In cases where the landowner or the landowner's agent or operator has refused assistance from the local soil and water conservation district in complying with or documenting compliance with the agricultural requirements of this chapter, the district shall report the noncompliance to the local government. The local government shall require the landowner to correct the problems within a specified period of time not to exceed 18 months from their initial notification of the deficiencies to the landowner. The local government, in cooperation with the district, shall recommend a compliance schedule to the landowner. This schedule shall expedite environmental protection while taking into account the seasons and other temporal considerations so that the probability for successfully implementing the corrective measures is greatest.

6. Water quality impact assessment. A water quality impact assessment shall be required for any proposed development within the Resource Protection Area consistent with this part and for any other development in Chesapeake Bay Preservation Areas that may warrant such assessment because of the unique characteristics of the site or intensity of the proposed use or development.

a. The purpose of the water quality impact assessment is to identify the impacts of proposed development on water quality and lands in the Resource Protection Areas consistent with the goals and objectives of the Act, this chapter, and local programs, and to determine specific measures for mitigation of those impacts. The specific content and procedures for the water quality impact assessment shall be established by each local government. Local governments should notify the department of all development requiring such an assessment.

b. The water quality impact assessment shall be of sufficient specificity to demonstrate compliance with the criteria of the local program.

7. Buffer area requirements for Intensely Developed Areas. In Intensely Developed Areas the local government may exercise discretion regarding whether to require establishment of vegetation in the 100-foot wide buffer area. However, while the immediate establishment of vegetation in the buffer area may be impractical, local governments shall give consideration to implementing measures that would establish vegetation in the buffer in these areas over time in order to maximize water quality protection, pollutant removal, and water resource conservation. In considering such measures, local governments shall consider the planting of trees as a component of any such measure. Inclusion of native species in tree planting is preferred.

9VAC25-830-150. Nonconformities, exemptions, and exceptions.

A. Nonconforming uses and noncomplying structures.

1. Local governments may permit the continued use, but not necessarily the expansion, of any structure in existence on the date of local program adoption.

TMDL Special Conditions

A. Chesapeake Bay TMDL special condition.

1. The Commonwealth in its Phase I, Phase II, and Phase III Chesapeake Bay TMDL Watershed Implementation Plans (WIPs) committed to a phased approach for MS4s, affording MS4 permittees up to three full five-year permit cycles to implement necessary reductions. This permit is consistent with the Chesapeake Bay TMDL and the Virginia Phase I, Phase II, and Phase III WIPs to meet the Level 2 (L2) scoping run for existing developed lands as it represents an implementation of an additional 60% of L2 as specified in the Phase I, Phase II, and Phase III WIPs. In combination with the 40% reduction of L2 that has already been achieved, a total reduction no later than October 31, 2028, of 100% of L2 shall be achieved. Conditions of future permits will be consistent with the TMDL or WIP conditions in place at the time of permit issuance.

2. The following definitions apply to Part II of this state permit for the purpose of the Chesapeake Bay TMDL special condition for discharges in the Chesapeake Bay Watershed:

"Existing sources" means pervious and impervious urban land uses served by the MS4 as of June 30, 2009.

"New sources" means pervious and impervious urban land uses served by the MS4 developed or redeveloped on or after July 1, 2009.

"Pollutants of concern" or "POC" means total nitrogen and total phosphorus.

"Transitional sources" means regulated ~~land disturbing~~ land-disturbing activities that are temporary in nature and discharge through the MS4.

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

L. Duty to comply. The operator shall comply with all conditions of this state permit. Any state permit noncompliance constitutes a violation of the Virginia Erosion and Stormwater Management Act and the Clean Water Act, except that noncompliance with certain provisions of this state permit may constitute a violation of the Virginia Erosion and Stormwater Management Act but not the Clean Water Act. Permit noncompliance is grounds for enforcement action; for state permit termination, revocation and reissuance, or modification; or denial of a state permit renewal application.

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

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

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

O. State law. Nothing in this state permit shall be construed to preclude the institution of any legal action under, or relieve the operator from any responsibilities, liabilities, or penalties established pursuant to any other state law or regulation or under authority preserved by § 510 of the Clean Water Act. Except as provided in state permit conditions on bypassing in Part IV U and upset in Part IV V nothing in this state permit shall be construed to relieve the operator from civil and criminal penalties for noncompliance.

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

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

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

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

U. Bypass.

1. "Bypass," as defined in ~~9VAC25-870-10~~ 9VAC25-875-850, means the intentional diversion of waste streams from any portion of a treatment facility. The operator may allow any bypass to occur that does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to ensure efficient operation. These bypasses are not subject to the provisions of Part IV U 2 and U 3.

2. Notice.

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

b. Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as required in Part IV I.

3. Prohibition of bypass.

a. Except as provided in Part IV U 1, bypass is prohibited, and the department may take enforcement action against an operator for bypass, unless:

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

(3) The operator submitted notices as required under Part IV U 2.

b. The department may approve an anticipated bypass, after considering its adverse effects, if the department determines that it will meet the three conditions listed in Part IV U 3 a.

V. Upset.

1. An "upset," as defined in ~~9VAC25-870-10~~ 9VAC25-875-850, means an exceptional incident in which there is unintentional and temporary noncompliance with technology based state permit effluent limitations because of factors beyond the reasonable control of the operator. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.

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

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

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

a. An upset occurred and that the operator can identify the causes 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 Part IV I; and

d. The operator complied with any remedial measures required under Part IV S.

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

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

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

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

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

4. Sample or monitor at reasonable times, for the purposes of ensuring permit compliance or as otherwise authorized by the Clean Water Act and the Virginia Erosion and 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. State permit actions. State permits may be modified, revoked and reissued, or terminated for cause. The filing of a request by the operator for a state permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any state permit condition.

Y. Transfer of state permits.

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

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

a. The current operator notifies the department at least 30 days in advance of the proposed transfer of the title to the facility or property;

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

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

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

B. Schedule of release of nutrient credits. The department shall establish a schedule for release of credits as follows:

1. For nutrient credit-generating projects using land use conversion, 25% of the credits will be released by the department after the department has verified completion of the conditions of the nutrient credit certification. For afforestation projects, an additional 25% of credits will be released by the department after the site has been planted with a minimum of 400 woody stems per acre. The remaining balance of credits will be released by the department after it is satisfied that the implementation plan's performance criteria required pursuant to 9VAC25-900-120 has been achieved. When a request for credit release is made concurrently with the application for nutrient credit certification from land conversion practices, the concurrent 25% initial release, and additional 25% release if planting has occurred, shall be processed on the same timeline as the application as provided in 9VAC25-900-80 C. When the request for credit release is from a previously approved land conversion project, the department shall schedule a site visit, if warranted, within 30 days of the request and shall deny, approve, or approve with conditions the release of the remaining 75% of the nutrient credits within 15 days of the site visit or determination that a site visit is not warranted.

2. For nutrient credit-generating projects using wetland or stream restoration, after construction 25% of the credits may be released by the department after the department has verified completion of the conditions of the nutrient credit certification. Every monitoring year thereafter, 25% of the credits may be released if all performance standards are met, the area or channel is stable, and, for streams, evidence is presented that a bankfull event occurred within the monitoring year. For streams, if a bankfull event did not occur, but performance standards are met and the channel is stable, 10% of the credits may be released. No additional credits will be released after the fourth monitoring year until a bankfull event has occurred. After the fourth monitoring year, if a bankfull event occurs, the channel is stable, and all performance standards are met, 25% of the credits may be released that monitoring year, not to exceed the remaining credits available. The schedule for release of credits shall also require, prior to the release of credits, the approval of any required financial assurance mechanism established pursuant to Part VI (9VAC25-900-230 et seq.) of this chapter. The department may accelerate the release of a maximum of 50% of nutrient credits from a stream restoration project based on (i) a determination that the level of risk for restoration failure is low; (ii) the provision of additional financial assurance in an amount adequate to cover the cost of project repair or replacement in the event of failure; and (iii) the experience of the applicant or the applicant's agents who will implement the stream restoration project.

3. For nutrient credit-generating projects using practices other than land use conversion or wetland or stream restoration, the schedule for release of credits will be determined by the department on a case-by-case basis and provided to the applicant with the nutrient credit certification. For projects using structural BMPs, the schedule shall also require, prior to release of credits, the approval of any required financial assurance mechanism established pursuant to Part VI (9VAC25-900-230 et seq.) of this chapter.

C. Registration of nutrient credits. Credits will be placed on the registry and classified as term or perpetual credits by the department. The registry will also indicate the number of credits that have been released for exchange. Only credits released by the department are available for exchange.

d. Cover crop. For croplands, cover crops shall be planted to meet the standard planting date and other specifications in accordance with DCR Specifications for NO. SL-8B contained in the VACS BMP Manual. This requirement applies to all croplands where summer annual crops are grown and the summer annual crop receives greater than a total of 50 pounds per acre of nitrogen application from any nutrient source; however, if the cropland is planted to winter cereal crops for harvest in the spring, then cover crops do not need to be planted on these croplands during that production year.

e. Livestock water body exclusion. For pastures or when livestock are present within the management area, livestock exclusion fencing shall be placed around perennial streams, rivers, lakes, ponds, or other water bodies having perennial flow. This exclusionary fencing shall be constructed in accordance with DCR Specification NO. WP-2W contained in the VACS BMP Manual in order to restrict livestock access to the water body.

(4) For poultry waste that is not stored inside or under a roofed structure, the storage area must be at least 100 feet from any surface water, intermittent drainage, wells, sinkholes, rock outcrops, and springs.

D. Urban practices. Achievement of baseline for new development, redevelopment, or retrofits to existing development shall be required prior to generation of credits. These baselines are:

1. For new development and redevelopment, baseline shall be achieved through compliance with the post-construction water quality design criteria requirements of the Virginia Erosion and Stormwater Management ~~Program (VSMP)~~ Regulation under ~~9VAC25-870-63~~ 9VAC25-875-580. Additionally, for development in a locality with a local stormwater management design criteria more stringent than ~~9VAC25-870-63~~ 9VAC25-875-580, baselines shall be achieved through compliance with the local stormwater management ordinance.

2. For retrofits within the Chesapeake Bay Watershed, baseline shall be at a level necessary to achieve the nutrient reduction assigned in the urban sector of the WIP or the approved local TMDL, whichever is more stringent.

3. For retrofits within the Southern Rivers watersheds and within a watershed with an approved TMDL with total phosphorus or total nitrogen allocations, baselines shall be at a level necessary to achieve reductions of the approved TMDL. For all other retrofits within the Southern Rivers watersheds, baseline shall be achieved through compliance with the post-construction water quality design criteria requirements for development on prior developed lands pursuant to ~~9VAC25-870-63~~ 9VAC25-875-580 A 2.

4. No credits may be certified for a nutrient credit-generating project owned by an MS4 permittee and located within the permittee's MS4 service area until the level of nutrient reduction required by the WIP or approved TMDL, whichever is more stringent, is achieved for the entire MS4 service area. MS4 permittees generating credits for exchange shall have an accounting system demonstrating that the exchanged credits are not used to satisfy the MS4 permit requirements.

E. Land use conversions. Baselines for land use conversion shall be established using the preconversion land use. The preconversion land use shall be based on the land use as of (i) July 1, 2005, for a nutrient credit-generating project located within the Chesapeake Bay Watershed; (ii) the date of the approved TMDL for a nutrient credit-generating project located within a TMDL watershed but not within the Chesapeake Bay Watershed; or (iii) July, 1, 2009, for a nutrient credit-generating project not within an approved TMDL watershed or the Chesapeake Bay Watershed.

F. Stream or wetland restoration. Baseline for stream restoration shall be established using the pre-restoration condition of the stream. Baseline for wetland restoration shall be established on a case-by-case basis, depending on the current land use of the proposed wetland restoration area.

G. Other nutrient credit-generating projects. The department shall establish baselines for other nutrient credit-generating projects not otherwise regulated by subsections B through F of this section. The practices necessary for establishing baseline at these other nutrient credit-generating projects shall be in accordance with the requirements of the WIP or the approved TMDL and shall utilize the best available scientific and technical information regarding the practices.

9VAC25-900-110. Credit calculation procedures.

A. Pursuant to this section, the applicant shall calculate the potential nutrient credits generated by the practices implemented at the nutrient credit-generating projects. The applicable delivery factors, dependent upon the tributary in which the nutrient credit-generating project is located, shall be applied when calculating the potential credits generated.

B. For agricultural practices, except land use conversion, the potential nutrient credits shall be calculated using removal efficiencies for practices approved by the department. In the Chesapeake Bay Watershed, these practices shall be approved by the department based on the efficiencies assigned by the Chesapeake Bay Program. In the Southern Rivers watersheds, these practices shall be approved by the department based on submitted calculations and demonstrations. The standards and specifications for implementation of the practices will be established by the department and shall be in accordance with the VACS BMP Manual or the FOTG, as applicable.

C. For urban practices, the potential nutrient credits shall be calculated using the applicable removal efficiencies pursuant to ~~9VAC25-870-65~~ 9VAC25-875-590 or using the best available scientific and technical information available at the time of nutrient credit certification as approved by the department. Limitations on potential nutrient credits from certain BMPs are:

1. In the Chesapeake Bay Watershed, nutrient load reductions from practices in place prior to July 1, 2005, may not be used to generate credits. Removal efficiencies shall be based upon those efficiencies approved by the Chesapeake Bay Program partnership where applicable. These efficiencies shall be reviewed at the time of certification renewal and adjusted as necessary based upon changes made by the Chesapeake Bay Program Partnership.

2. In the Southern Rivers watersheds, nutrient load reductions from practices in place prior to July 1, 2009, may not be used to generate credits.

D. For land use conversions, conversion of land to a more intensive land use activity will not generate nutrient credits. The number of potential nutrient credits shall be determined by calculating the nutrient credits per acre and multiplying that number by the total acreage that will undergo land use conversion. The nutrient credits per acre is equal to the amount calculated by subtracting the load per acre of nutrient nonpoint source pollution for the proposed land use after conversion from the load per acre for the preconversion land use. The values used for the loadings per acre in this calculation shall be based on the applicable loading levels provided in the WIP or the approved TMDL, where applicable. The preconversion land use shall be based on the land use as of the date specified in 9VAC25-900-100 E. The load per acre for the preconversion land use shall reflect the implementation of any applicable baseline practices necessary to comply with 9VAC25-900-100 B, C, and D. No credits shall be generated from the conversion of land within 35 feet of a water body with perennial water flow as measured from the top of the channel bank.

E. For wetland or stream restoration, an existing conditions assessment survey will be completed prior to restoration activities to use as a pre-restoration condition (baseline pursuant to of 9VAC25-900-100 F) and will be used for comparison to post-restoration conditions. The potential number of credits shall be determined by applying protocols or guidance on a case-by-case basis using the best available scientific and technical information, as approved by the department.

F. For a practice not previously approved by the department, the department will perform a case-by-case review in order to calculate the number of potential nutrient credits generated. The owner shall submit the removal efficiency calculation information for the practice and the calculation of the potential number of credits generated using that efficiency. The department may also request that the submittal include requirements for demonstration projects, the collection of sufficient data to evaluate the results, and any other information the department deems necessary to determine the validity of the credits. In the Chesapeake Bay Watershed, for a practice not approved by the Chesapeake Bay Program Partnership, the department will perform a case-by-case review in order to calculate the number of potential nutrient credits generated on a term basis.

G. In the certification and recertification of credits, the department may substitute a delivery factor that is deemed by the director to be based on the best available scientific and technical information appropriate for the tributaries located outside of the Chesapeake Bay Watershed as an alternative to any delivery factor derived from the application of the Chesapeake Bay Program watershed model.

9VAC25-900-230. Financial assurance applicability.

A. An owner of a nutrient credit-generating project that utilizes structural BMPs for the generation of perpetual credits shall submit and maintain financial assurance in accordance with this part. The financial assurance mechanism shall be submitted to and approved by the department prior to the release of credits.

B. An owner of a nutrient credit-generating project that utilizes structural BMPs for the generation of term credits with terms that exceed one year shall submit and maintain financial assurance in accordance with this part. However, an owner of a nutrient credit-generating project that utilizes structural BMPs for the generation of term credits with terms that exceed one year shall not be required to submit and maintain financial assurance in accordance with this part, provided that the department annually approves the generation of the term nutrient credits prior to release of the credits. In accordance with 9VAC25-900-90 B, the financial assurance mechanism shall be submitted to and approved by the department prior to the release of credits. For the purposes of this part, term credit shall refer to credit with a term greater than one year but not perpetual.

C. An owner of a nutrient credit-generating project using proposed new wetland or stream restoration practices not subject to 33 CFR 332.8 and § 62.1-44.15:23 of the Code of Virginia for the generation of perpetual credits shall be required to submit and maintain financial assurance in accordance with this chapter. In accordance with 9VAC25-900-90 B, the financial assurance mechanism shall be submitted to and approved by the department prior to the release of credits. The following financial assurances shall be provided for these new wetland or stream restoration projects:

1. A monitoring plan financial assurance mechanism shall be established to ensure implementation of the monitoring plan pursuant to 9VAC25-900-120 for any nutrient credits generated from wetland or stream restoration. When the owner conducts the required monitoring and submits a complete monitoring report as specified in the monitoring plan and report requirements, then the owner may request a reduction of the required financial assurance amount equivalent to the cost of one year of monitoring, subject to department approval. If any funds remain in the financial assurance mechanism after the monitoring period, the mechanism shall be maintained until the final monitoring report is submitted and approved, at which point the mechanism shall be released by the department;

2. A long-term management fund financial assurance mechanism shall be established in support of required long-term management plan tasks pursuant to 9VAC25-900-120 for any nutrient credits generated from wetland or stream restoration. Long-term management funds shall be placed in a separate interest bearing trust account in an appropriate financial institution and may be funded from a sufficient percentage of all credit sale proceeds, a single lump sum payment, or an approved schedule of payments, subject to department approval. No long-term management funds shall be used to finance any expense or activity other than those specified in the long-term management plan unless approved by the department. Responsibility for and access to the long-term management fund is given to the owner or long-term steward and may be transferred to any new long-term steward that is designated by the owner and approved by the department; and

3. In lieu of the long-term management fund trust account for stream restoration projects established in subdivision 2 of this subsection, a third-party long-term steward approved by the department, such as a public agency, nongovernmental organization, or private land manager, may hold long-term management funds in a separate interest-bearing account to be used only for the long-term management of the stream restoration project.

D. When the nutrient credits are generated or used by a locality, authority, utility, sanitation district, or owner operating an MS4 or a point source permitted under ~~9VAC25-870~~ 9VAC25-875, the existence of tax or rate authority may be used by such entity at its option in satisfaction of the financial assurance required pursuant to this part.
