Nature of activity (Provide a detailed narrative of the construction activities. Include or reference a construction schedule and sequence. Include any phasing.) The project documents are the plans for the project entitled "Albemarle County Service Authority Avon Maintenance Yard" (Plan Sheets: G0.01, C0.01-Co.07, C1.01-C1.03, C2.01-C2.06, C3.01-C3.07, C4.01-C4.19, C5.01-05.06, C6.01 -C6. 10), dated 10/5/2022, which address most of the information required in the Stormwater Pollution Prevention Plan (SWPPP). Information not found in these documents is identified below. Project Description: The Albemarle County Service Authority seeks to construct a vehicle maintenance building, site access road, parking lots, training area, fuel station, and vehicle wash area. The site is located at 1737 Avon Street Ext. Project Sequence: The project includes the installation of erosion sediment control features. Once erosion control measures are adequately and completely installed, demolition, clearing and grubbing operations will occur prior to installation of the new improvements. Once installation of all site features and hardscape is completed, the construction shall be followed by final stabilization. Project Area Disturbance: The expected area of disturbance is approximately 7.31 acres and 3.30 acres of this will be impervious. Potential Pollution Sources: Other potential sources of storm water pollution include chemicals, concrete, paint, tar, wood, metal, fuel, oil, and other fluids associated with heavy equipment, and fertilizer used in seeding and sodding. Though structural control measures such as containment diking are impossible on a construction site, care will be taken to reduce the risk of spills. Fueling operations will be continuously supervised. Fertilizer and other materials stored on site will be covered to reduce the possibility of contact with stormwater.

A GEOTECHNICAL ENGINEER SHOULD BE PRESENT DURING AND AFTER CONSTRUCTII TO MONITOR, REPORT AND VERIFY STABILITY AND COMPACTION OF DAM. 2. ACUTOFF TRENCH SHALL BE EXCAVATED ALONG THE CENTERLINE OF THE DAM. THE TRENCH MUST EXTEND AT LEAST I FOOT INTO A STABLE, IMPERVIOUS LAYER OF SOIL AND HAVE MINIMUM DEPTH OF 2FT. THE MINIMUM BOTTOM WIDTH SHALL BE FEET. THE SIDE SLOPES SHAyl BE NO STEEPER THAT 1:1 SEQUENCE OF CONSTRUCTION NARRATIVE STEP 1: INSTALL ESS PERIMETER CONTROLS PRIOR TO CONSTRUCTON. INCLUDING TEMPORARY OF WATERING DEVICES AND STORMWATER DIVERSIONS. UTILIZE SWM 1 AS TEMPORARY SEDIMENT BASIN DURING CONSTRUCTION. EXCAVATE / GRADE UNTIL THE APPROPRIATE ELEVATIONS AND DESIRED CONTOURS ARE ACHIEVED FOR THE BOTTOM AND SIDE SLOPES OF THE SEDIMENT BASIN. INSTALLATION OF THE PERMANENT CULVERT AND RISER STRUCTURE SHOULD BE INITIATED DURING THE CONSTRUCTION PHASE. STEP 2: EXCAVATE THE CORE TRENCH AND INSTALL THE PERMANENT OUTLET PIPE, INCLUDING THE DOWNSTREAM RIPRAP ARGON. INSTALL THE RISER TO THE INVERT ELEVATIONS AS SHOWN ABOVE. STEP 3: CONSTRUCT THE EMBANKMENT IN B TO 12 INCH LIFTS AND COMPACT THE LIFTS TO THE APPROPRIATE ELEVATION. CONSTRUCT THE EMERGENCY$PILLWAY. STEP 4: ASSEMBLE MATERIAL ON SITE MAKE SURE THEY MEET SPECIFICATIONS, AND PREPARE ANY STAGING AREAS. CLEAR AND STRIP THE PROJECT AREA AND CONSTRUCT SITE TO DESIRED SUBGRADE. STEP 5: AFTER COMPLETION OF CONSTRUCTION OF THE SITE, STABILIZE THE ENTIRE DRAINAGE AREA. THE PERMANENT DETENTION POND SHOULD ONLY BE CONSTRUCTED AFTER THE CONTRIBUTING DRAINAGE AREA TO THE FOND IS COMPLETELY STABILIZED. STEP B: AFTER THE SITE CONSTRUCTION IS COMPLETE TO REMOVE SEDIMENT AS NECESSARY. STEP EXCAVATE GRADE UNTIL THE APPROPRIATE FINAL ELEVATIONS AND DESIRED CONTOURS ARE ACHIEVED FOR THE BOTTOM AND SIDE SLOPES OF THE POND. FINISH CONSTRUCTING THE EMBANMENT TO THE PERMANENT ELEVATION AND INSTALL THE ACCESS ROA➢. INSTALL ANY INTERNAL BERMS IN 8 TO 121NCH LIFTS AND COMPACTTO THE APPROPRIATE ELEVATION.

Please see attached erosion and sediment control plans for detailed methodology. Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County 6.0 POLLUTION PREVENTION PLAN 6.1 POTENTIAL SOURCES OF POLLUTION Soil disturbing activities associated with the construction of the UVA Golf Facility project potentially affect the quality of stormwater runoff. Therefore, proper erosion and sediment control measures will be installed prior to construction to manage stormwater and sediment. The location of potential pollutant sources should be documented and updated on the plans for the project. The limit of disturbance is the area identified as the likely location where potential spills and leaks may occur. 6.2 POLICIES AND The operator should assure that employees are aware of applicable wastes, including wash water, disposal practices, and applicable disposal locations of such wastes, in order to comply with the conditions of the Permit. Personnel should be educated in spill prevention, area of possible pollution, and spill response procedures. 6.3 MANAGEMENT PRACTICES AND OTHER CONTROLS 6.3.1 Good Housekeeping Good housekeeping requires all personnel to maintain cleanliness and order in areas that could cause stormwater contamination. The following is a list of techniques that personnel should incorporate as good housekeeping practices on a daily basis: • Keep outside areas neat and orderly; clean drips and/or fix leaks from on -site equipment and inspect regularly; • Maintain a supply of spill response equipment; • Use watering truck to minimize dust; and, • Pick up windblown debris. 6.3.2 Minimizing Exposure Where practicable, protect industrial materials and activities with a storm -resistant shelter to prevent exposure to rain, snow, snowmelt, or runoff. 6.3.3 Existing Vegetation Preservation of existing vegetation will be practiced where possible. Areas not to be disturbed are shown on the Major Site Development Plans set and shall be delineated and clearly marked as a first step in construction. 6.4 SPILL PREVENTION AND RESPONSE The following practices will be followed for spill prevention and cleanup: • Products will be kept in original containers with the original manufacturer's label, where possible, unless they are not re -sealable. • Materials stored on -site will be stored in a neat, orderly manner in their appropriate containers. Materials that have the potential for contaminating runoff during storm events will be stored in their appropriate watertight containers, under a canopy, tarpaulin, shrink-wrapped, or otherwise precluded from direct exposure to precipitation. • Whenever possible, all of a product will be used before disposing of the container. If surplus product must be disposed of, manufacturers' and/or local and State recommended methods for proper disposal will be followed. • Manufacturers' recommendations for proper use and disposal will be followed. • If applicable, manufacturers' recommended methods for spill cleanup will be maintained on -site and site personnel will be made aware of the procedures and the location of the information and cleanup supplies. • If applicable, Materials and equipment necessary for spill cleanup will be kept in the material storage area on -site. Equipment and materials may include, but not be limited to, cleanup kits, brooms, dust pans, mops, rags, gloves, goggles, dirt to contain spills, containment boom, absorbent material (e.g., hay, kitty litter, sand, sawdust), and plastic and metal trash containers. • Spills will be cleaned up immediately after discovery. • In the event of a discharge of a potential pollutant or spill of a hazardous substance, the following steps should be taken: 1. Eliminate potential spark sources; 2. If possible and safe to do so, identify and shut down the source of the discharge to stop the flow; 3. Contain the discharge with sorbent, berms, fences, trenches, sandbags, or other material and ensure the area will be kept well ventilated. Personnel will wear appropriate protective clothing to prevent injury from contact with a hazardous substance during cleanup operations; 4. Contact the SWPPP Coordinator or his/her designee (Division Manager) or his/her alternate; 5. Contact regulatory authorities and the response organization as required by regulatory standards; and 6. Collect and dispose of recovered products according to applicable regulations. • Spills of toxic or hazardous material will be reported to the appropriate State and local government agency, as required by regulatory standards. The contractor or his representative will be responsible for spill prevention and coordination. • The spill prevention and control procedures will be implemented once construction begins on -site. When a spill occurs, the individuals/agencies in Table 6 shall be considered for notification.

For emergencies, the Virginia Department of Emergency Management maintains a 24-hour telephone service at 1-800-468-8892. 6.6 FUELING AND MAINTENANCE OF EQUIPMENT OR VEHICLES • The locations of all vehicle fueling areas will be documented in the SWPPP. These locations can be identified on the E&S Plan provided in Appendix C of the SWPPP. As the vehicle fueling facilities move throughout the project, areas need to be shown, dated, and signed. If vehicle fueling will not be part of the project, a written statement indicating that "no on -site vehicle fueling will be part of this project" should be added on the plans or included in the Log of Changes in Appendix G of the SWPPP. • On -site vehicles will be monitored for leaks and receive regular preventive maintenance to reduce the chance of leakage. • Refueling, repairs, and changing of equipment and vehicle fluids will be conducted in a manner to reduce the potential for contamination of on -site resources. Care should be taken, where feasible, to avoid activities within ±50 feet of storm drains, wetlands, streams, water bodies, tree preservation areas, or any other environmentally sensitive areas. • Secondary containment and spill response kits should be provided on -site. • These pollution prevention practices and procedures should be implemented to prevent the discharge of spilled and leaked fuels and chemicals from vehicle fueling and maintenance activities (e.g., providing secondary containment such as spill berms, decks, spill containment pallets, providing cover where appropriate, and having spill kits readily available). • Petroleum products will be stored in tightly sealed containers that are clearly labeled. • Any asphalt substances used on -site will be applied according to the manufacturer's recommendations. • The contractor will regularly inspect the site to ensure that proper disposal methods of used antifreeze, oils, filters, and other hazardous materials are followed. 6.7 WASHING OF EQUIPMENT AND VEHICLES • Vehicle washing should not use soaps, solvents, or detergents. • Construction vehicle washing will only occur at approved locations in accordance with State and local regulations. The Guidelines for Vehicle and Equipment Washing is included in Appendix I. • Tire washing may be necessary as part of the site's construction entrance in order to minimize the transport of sediment by vehicular traffic onto a paved surface. If tire washing is necessary, provisions must be made to intercept the wash water and trap the sediment so it can be collected and stabilized. Wash water must be diverted away from the construction entrance to an approved settling area to remove sediment. Pollution prevention practices and procedures should be implemented that will minimize the discharge of pollutants from vehicle and equipment washing, wheel wash water, and other types of washing (e.g., locating activities away from surface waters and stormwater inlets, directing wash waters to sediment basins or traps, using filtration devices such as filter bags or sand filters, or using similarly effective controls), and the wash water should be filtered, settled, or similarly treated prior to discharge. • Physical separation should be provided between surface waters and inlets. 6.8 STORAGE, HANDLING, AND DISPOSAL OF CONSTRUCTION PRODUCTS, MATERIALS, AND WASTES In addition to the practices listed below, the practices in Section 5.4 - Spill Prevention and Response apply to the storage, handling, and disposal of construction products, materials, and wastes. Examples of these items include asphalt sealants, copper flashing, scrap building materials, adhesives, concrete admixtures, pesticides, herbicides, fertilizers, landscape materials, timber, pipe and electrical cuttings, diesel fuel, oil and hydraulic fluids, as well as paint and other petroleum products. Waste materials will be collected and stored in a proper receptacle in accordance with local and State solid waste management regulations. Trash and construction debris from the site will be deposited in dumpsters. The locations of the dumpsters shall be documented in the SWPPP once determined in the field. These locations will be annotated on the E&S Plan. The trash will be hauled to an appropriate waste disposal site. No construction waste materials shall be buried on -site. Project personnel shall be instructed regarding the correct procedure for waste disposal. • Chemical or petroleum products will not be mixed with one another unless recommended by the manufacturer. • On -site equipment shall be checked for leaks and receive regular preventive maintenance. • Hazardous waste materials will be disposed of in the manner specified by the manufacturer and as required by local or State regulation. Site personnel will be instructed in these practices. • Portable sanitary units will be utilized at various locations along the project site. The locations of the portable sanitary units shall be documented in the SWPPP once determined in the field. As (or if) the units move, the movement of the facilities shall be documented in the SWPPP with initials of the individual authorizing the movement and a corresponding date. These locations will be annotated on the E&S Plans. Sanitary waste will be collected from the portable units as required by local and State regulation. • Portable sanitary units shall not be located in or adjacent to streams, drop inlets, stormwater flow paths, and floodplains. G�L�S'LJ.7 I1►[K1]9[KI]�[y R pr r ors X111 r:1 DI MrA MM;� r_� &y • Concrete trucks will only wash out or discharge surplus concrete or drum wash water at approved locations in accordance with State and local regulations. • The discharge of wastewater from the washout of concrete is prohibited. Direct concrete wash water into a leak -proof container or leak -proof settling basin. The container or basin shall be designed so that no overflows can occur due to inadequate sizing or precipitation. Hardened concrete wastes shall be removed and disposed of in a manner consistent with the handling of other construction wastes. Liquid concrete wastes shall be removed and disposed of in a manner consistent with the handling of other construction wash waters and shall not be discharged to surface waters. See Environmental Protection Agency (EPA) Fact Sheet for concrete washout at http://www.epa.goy/npdes/pubs/concretewashout.pdf (provided in Appendix I of the SWPPP). • Washout areas are expected to be at designated construction entrance locations. The locations of the concrete washout areas shall be documented in the SWPPP once determined in the field. These locations should be identified on the E&S Plan in Appendix C of the SWPPP.

The inspection report and any actions taken in accordance with Part II shall be retained by the operator as part of the SWPPP for at least three years from the date that general permit coverage expires or is terminated. The inspection report shall identify any incidents of noncompliance. Where an inspection report does not identify any incidents of noncompliance, the report shall contain a certification that the construction activity is in compliance with the SWPPP and this general permit. The report shall be signed in accordance with Part III K of this general permit. H. Corrective actions. The operator shall implement the corrective actions identified as a result of an inspection as soon as practicable but no later than seven days after discovery or a longer period as approved by the VSMP authority. If approval of a corrective action by a regulatory authority (e.g., VSMP authority, VESCP authority, or the department) is necessary, additional control measures shall be implemented to minimize pollutants in stormwater discharges until such approvals can be obtained. The operator may be required to remove accumulated sediment deposits located outside of the construction activity covered by this general permit as soon as practicable in order to minimize environmental impacts. The operator shall notify the VSMP authority and the department as well as obtain all applicable federal, state, and local authorizations, approvals, and permits prior to the removal of sediments accumulated in surface waters including wetlands. Page 18 of 26 PART III CONDITIONS APPLICABLE TO ALL VPDES PERMITS NOTE: Discharge monitoring is not required for this general permit. If the operator chooses to monitor stormwater discharges or control measures, the operator shall comply with the requirements of subsections A, B, and C, as appropriate. A. Monitoring. 1. Samples and measurements taken for the purpose of monitoring shall be representative of the monitoring activity. Monitoring shall be conducted according to procedures approved under 40 CFR Part 136 or alternative methods approved by the U.S. Environmental Protection Agency, unless other procedures have been specified in this general permit. Analyses performed according to test procedures approved under 40 CFR Part 136 shall be performed by an environmental laboratory certified under regulations adopted by the Department of General Services (1 VAC30-45 or 1 VAC30-46). 3.

Monitoring records and reports shall include a. The date, exact place, and time of sampling or measurements; b. The individuals who performed the sampling or measurements; c. The dates and times analyses were performed; d. The individuals who performed the analyses; e. The analytical techniques or methods used; and f. The results of such analyses. 2. The operator shall retain records of all monitoring information, including all calibration and maintenance records and all original strip chart recordings for continuous monitoring instrumentation, copies of all reports required by this general permit, and records of all data used to complete the registration statement for this general permit, for a period of at least three years from the date of the sample, measurement, report or request for coverage. This period of retention shall be extended automatically during the course of any unresolved litigation regarding the regulated activity or regarding control standards applicable to the operator, or as requested by the board. C. Reporting monitoring results. Page 19 of 26 1. The operator shall update the SWPPP to include the results of the monitoring as may be performed in accordance with this general permit, unless another reporting schedule is specified elsewhere in this general permit. 2. Monitoring results shall be reported on a discharge monitoring report (DMR); on forms provided, approved or specified by the department; or in any format provided that the date, location, parameter, method, and result of the monitoring activity are included. If the operator monitors any pollutant specifically addressed by this general permit more frequently than required by this general 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 general 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 which require averaging of measurements shall utilize an arithmetic mean unless otherwise specified in this general permit. D. Duty to provide information. The operator shall furnish, within a reasonable time, any information which the board may request to determine whether cause exists for terminating this general permit coverage or to determine compliance with this general permit. The board, department, EPA, or VSMP authority may require the operator to furnish, upon request, such plans, specifications, and other pertinent information as may be necessary to determine the effect of the wastes from his discharge on the quality of surface waters, or such other information as may be necessary to accomplish the purposes of the CWA and the Virginia Stormwater Management Act. The operator shall also furnish to the board, department, EPA, or VSMP authority, upon request, copies of records required to be kept by this general 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 general permit shall be submitted no later than 14 days following each schedule date. F. Unauthorized stormwater discharges. Pursuant to § 62.1-44.5 of the Code of Virginia, except in compliance with a state permit issued by the department, it shall be unlawful to cause a stormwater discharge from a construction activity. G. Reports of unauthorized discharges. Any operator who discharges or causes or allows a discharge of sewage, industrial waste, other wastes or any noxious or deleterious substance or 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, 40 CFR Part 302, or § 62.1-44.34:19 of the Code of Virginia that occurs during a 24-hour period into or upon surface waters or who discharges or causes or allows a discharge that may reasonably be expected to enter surface waters, shall notify the Department of Environmental Quality of the discharge immediately upon discovery of the discharge, but in no case later than within 24 hours after said discovery. A written report of the unauthorized discharge shall be submitted to the department and the VSMP authority 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; Page 20 of 26 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 Any steps planned or taken to reduce, eliminate and prevent a recurrence of the present discharge or any future discharges not authorized by this general permit. Discharges reportable to the department and the VSMP authority 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," as defined in this general permit, should occur from a facility and the discharge enters or could be expected to enter surface waters, the operator shall promptly notify, in no case later than within 24 hours, the department and the VSMP authority 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 operator shall reduce the report to writing and shall submit it to the department and the VSMP authority within five days of discovery of the discharge in accordance with Part III 12. 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 of some or all of the facilities; and 4. Flooding or other acts of nature. I. Reports of noncompliance. The operator shall report any noncompliance which may adversely affect surface waters or may endanger public health. An oral report to the department and the VSMP authority shall be provided within 24 hours from the time the operator becomes aware of the circumstances. The following shall be included as information that shall be reported within 24 hours under this subdivision: a. Any unanticipated bypass; and b. Any upset that causes a discharge to surface waters. 2. A written report shall be submitted within five days and shall contain: a. A description of the noncompliance and its cause; Page 21 of 26 b. 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 c. Steps taken or planned to reduce, eliminate, and prevent reoccurrence of the noncompliance. The department 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 surface waters has been reported. 3. The operator shall report all instances of noncompliance not reported under Part III 1 1 or 2 in writing as part of the SWPPP. The reports shall contain the information listed in Part 111 1 2. NOTE: The reports required in Part III G, H and I shall be made to the department and the VSMP authority. Reports may be made by telephone, email, or by fax. For reports outside normal working hours, leaving a recorded message shall fulfill the immediate reporting requirement. For emergencies, the Virginia Department of Emergency Management maintains a 24-hour telephone service at 1-800-468-8892. 4. Where the operator becomes aware of a failure to submit any relevant facts, or submittal of incorrect information in any report, including a registration statement, to the department or the VSMP authority, the operator shall promptly submit such facts or correct information. J. Notice of planned changes. 1. The operator shall give notice to the department and the VSMP authority as soon as possible of any planned physical alterations or additions to the permitted facility or activity. Notice is required only when: a. The operator plans an alteration or addition to any building, structure, facility, or installation that may meet one of the criteria for determining whether a facility is a new source in 9VAC25-870-420; b. The operator plans an alteration or addition that would significantly change the nature or increase the quantity of pollutants discharged. This notification applies to pollutants that are not subject to effluent limitations in this general permit; or 2. The operator shall give advance notice to the department and VSMP authority of any planned changes in the permitted facility or activity, which may result in noncompliance with state 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 purpose of this chapter, 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 Page 22 of 26 manager is authorized to make management decisions that govern the operation of the regulated facility including having the explicit or implicit duty of making major capital investment recommendations, and initiating and directing other comprehensive measures to assure long-term compliance with environmental laws and regulations; the manager can ensure that the necessary systems are established or actions taken to gather complete and accurate information for state permit application requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures; 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 chapter, 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 this general permit, including SWPPPs, and other information requested by the board or the department 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 operator. (A duly authorized representative may thus be either a named individual or any individual occupying a named position); and c. The signed and dated written authorization is included in the SWPPP. A copy shall be provided to the department and VSMP authority, if requested. 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 construction activity, a new authorization satisfying the requirements of Part III K 2 shall be submitted to the VSMP authority as the administering entity for the board 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 I have read and understand this document and that this document and all attachments were prepared in accordance with a system designed to assure that qualified personnel properly gathered and evaluated 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 Page 23 of 26 penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations." L. Duty to comply. The operator shall comply with all conditions of this general permit. Any state permit noncompliance constitutes a violation of the Virginia Stormwater Management Act and the Clean Water Act, except that noncompliance with certain provisions of this general permit may constitute a violation of the Virginia Stormwater Management Act but not the Clean Water Act. Permit noncompliance is grounds for enforcement action; for state permit coverage, 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 general 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 general permit after the expiration date of this general permit, the operator shall submit a new registration statement at least 60 days before the expiration date of the existing general 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 general permit. N. Effect of a state permit. This general 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 general 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 general permit conditions on "bypassing" (Part III U) and "upset' (Part III V), nothing in this general permit shall be construed to relieve the operator from civil and criminal penalties for noncompliance. P. Oil and hazardous substance liability. Nothing in this general 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 general 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 general 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 surface waters and in compliance with all applicable state and federal laws and regulations. Page 24 of 26 S. Duty to mitigate. The operator shall take all steps to minimize or prevent any discharge in violation of this general 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 general permit. U. Bypass. 1. 'Bypass," as defined in 9VAC25-870-10, 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 III U 2 and 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 III I. 3. Prohibition of bypass. a. Except as provided in Part III U 1, bypass is prohibited, and the board or 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. Severe property damage means substantial physical damage to property, damage to the treatment facilities that causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production; (2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventive maintenance; and (3) The operator submitted notices as required under Part III 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 III U 3 a. Page 25 of 26 V. Upset. 1. An "upset," as defined in 9VAC25-870-10, 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 III 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 preventative 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 cause 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 III I; and d. The operator complied with any remedial measures required under Part III 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 as the board's designee, the VSMP authority, EPA, or an authorized representative of either entity (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 shall be kept under the conditions of this general permit; 2. Have access to and copy, at reasonable times, any records that shall be kept under the conditions of this general permit; 3. Inspect and photograph at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this general permit; and 4. Sample or monitor at reasonable times, for the purposes of ensuring state permit compliance or as otherwise authorized by the Clean Water Act or the Virginia Stormwater Management Act, any substances or parameters at any location. Page 26 of 26 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 herein shall make an inspection unreasonable during an emergency. X. State permit actions. State permit coverage 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 permit coverage. 1. State permits are not transferable to any person except after notice to the department. Except as provided in Part III 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 Stormwater Management Act and the Clean Water Act. As an alternative to transfers under Part III 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 III Y 2 b. 3. For ongoing construction activity involving a change of operator, the new operator shall accept and maintain the existing SWPPP, or prepare and implement a new SWPPP prior to taking over operations at the site. Z. Severability. The provisions of this general permit are severable, and if any provision of this general 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 general permit shall not be affected thereby.
