DSWC 3.08 1992 EROSION CONTROL NOTES & NARRATIVE PURPOSE: THE PURPOSE OF THIS LAND DISTURBING ACTIVITY IS TO GRADE THE SITE TO FOR A CAR WASH AND ASSOCIATED PARKING LOT. THE TOTAL AREA TO BE DISTURBED WITH THIS PLAN IS 0.59 ACRES. EXISTING SITE CONDITIONS: THIS SITE IS MAINLY A GRASSED AREA WITH WOODS AND SLOPES TO THE NORTHWEST. THE SITE IS LOCATED TO THE WEST OF PANTOPS SHOPPING CENTER PARKING LOT BY ENTERPRISE RENT -A -CAR. A PORTION OF THE SITE JUST NORTH OF ENTERPRISE RENT -A -CAR IS CURRENTLY PAVED. THE MAJORITY OF THE SITE DRAINS DIRECTLY NORTHWEST TOWARDS THE RIVANNA RIVER. ADJACENT AREAS: THIS SITE IS BORDERED TO THE NORTHWEST BY VACANT LAND ALONG THE RIVANNA RIVER, TO THE SOUTH BY EXISTING COMMERCIAL BUILDING, TO THE EAST BY PANTOPS SHOPPING CENTER PARKING LOT, AND TO THE NORTH BY ETERPRISE RENT -A -CAR. OFFSITE LAND DISTURBANCE: NO OFFSITE LAND DISTURBANCE IS PROPOSED WITH THIS PLAN. CRITICAL AREAS: TREE PROTECTION FENCING AND SILT FENCE SHALL BE MAINTAINED ALONG THE NORTHWEST PROPERTY LINES AS SHOWN ON THE PLAN TO PROTECT THE ADJACENT PROPERTIES. CONTRACTOR SHALL ENSURE THAT ALL SEDIMENT MAINTENANCE CONTROLS ARE ALONG THE PARKING LOT ENTRANCE TO ENSURE THAT NO SEDIMENT LEAVES THE SITE AND DRAINS ONTO THE ROADS. SOILS: SOILS MAP IS INCORPORATED INTO EROSION CONTROL PLAN PHASE I WITH SOILS DATA INCLUDED WITH THIS NARRATIVE. SEQUENCE OF CONSTRUCTION: PHASE I: 1. NOTIFY ALBEMARLE COUNTY TO SCHEDULE A PRE -CONSTRUCTION MEETING AS REQUIRED. 2. PRIOR TO DISTURBANCES, THE LIMITS OF DISTURBANCE SHALL BE FLAGGED AND THE TREE PROTECTION FENCING SHALL BE INSTALLED. 3. NO EROSION CONTROL MEASURES MAY BE REMOVED DURING THE CONSTRUCTION PROCESS WITHOUT THE APPROVAL FROM THE INSPECTOR ON THE PROJECT. 4. THE PROPOSED CONSTRUCTION ENTRANCE WITH WASH AREAS SHALL BE INSTALLED AS SHOWN ON THE PLANS. THE CONSTRUCTION ENTRANCE TO BE INSTALLED WHERE CONSTRUCTION VEHICLE ROUTES INTERSECT PAVED PUBLIC ROADS, PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY (VEHICULAR) TRACKING ONTO THE PAVED SURFACE. WHERE SEDIMENT IS TRANSPORTED ONTO A PUBLIC ROAD SURFACE, THE ROAD SHALL BE CLEANED THOROUGHLY AT THE END OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING AND TRANSPORTING TO A SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER. 5. INSTALL THE INITIAL CONSTRUCTION MEASURES AS SHOWN ON THE PHASE I EROSION CONTROL SHEET. THIS INCLUDES WIRE SILT FENCE AND INLET PROTECTION. MEASURES INTENDED TO TRAP SEDIMENT SHALL BE CONSTRUCTED AS A FIRST STEP WITH ANY LAND DISTURBANCE ACTIVITY AND SHALL BE MADE FUNCTIONAL BEFORE UPSLOPE LAND DISTURBANCE TAKES PLACE. 6. ONCE ALL THE PHASE I EROSION CONTROL ITEMS HAVE BEEN INSTALLED AS SHOWN ON THE EROSION CONTROL PHASE I PLAN AND THE INSPECTOR HAS APPROVED THE EROSION CONTROL MEASURES, THE CONTRACTOR CAN BEGIN THE MINIMUM GRADING OPERATIONS AND BUILDING THE RETAINING WALL. STABILIZATION MEASURES SHALL BE APPLIED TO EARTHEN STRUCTURES SUCH AS DAMS, DIKES, AND DIVERSIONS IMMEDIATELY AFTER INSTALLATION. THE CONCRETE RETAINING WALL SHALL BE CONSTRUCTED FIRST TO PROTECT THE DOWNSTREAM PRESERVED SLOPES. THE CONTRACTOR SHALL EXCAVATE ONLY WIDE ENOUGH TO INSTALL THE 3' FOOTER AND 10" WALL, AS SHOWN IN THE DETAIL ON SHEET 3. ONCE THE WALL IS CONSTRUCTED, THE REMAINING PORTION OF THE SITE CAN BE GRADED PER THE PLAN. 7. ONCE ROUGH GRADING IS COMPLETE, CONTRACTOR CAN BEGIN INSTALLING UTILITIES, ROAD/SIDEWALK CONSTRUCTION, AND BUILDING THE CAR WASH BUILDING. INLET PROTECTION SHALL BE APPLIED TO INLETS AS THEY ARE BUILT AS SHOWN ON THE PLAN. 8. PERMANENT OR TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED AREAS WITHIN SEVEN DAYS AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. TEMPORARY SOIL STABILIZATION SHALL BE APPLIED WITHIN SEVEN DAYS TO DENUDED AREAS THAT MAY NOT BE AT FINAL GRADE BUT WILL REMAIN DORMANT (UNDISTURBED) FOR LONGER THAN 30 DAYS. PERMANENT STABILIZATION SHALL BE APPLIED TO AREAS THAT ARE TO BE LEFT DORMANT FOR MORE THAN ONE YEAR. PHASE II: 9. ONCE THE SITE IS STABILIZED AND THE INSPECTOR HAS GIVEN APPROVAL, THE CONTRACTOR CAN BEGIN REMOVAL OF SEDIMENT TRAPPING MEASURE. NO ITEM SHALL BE REMOVED UNLESS THE UPSTREAM AREAS ARE STABILIZED AND THE INSPECTOR GIVES PERMISSION. 10. MAINTAIN ALL EROSION CONTROL MEASURES AS SPECIFIED IN THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, REMOVING ONLY WHEN APPROVED BY THE LOCAL PROGRAM ADMINISTRATOR IN ACCORDANCE WITH THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. 11. ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION OR AFTER THE TEMPORARY MEASURES ARE NO LONGER NEEDED, UNLESS OTHERWISE AUTHORIZED BY THE LOCAL PROGRAM ADMINISTRATOR. TRAPPED SEDIMENT AND THE DISTURBED SOIL AREAS RESULTING FROM THE DISPOSITION OF TEMPORARY MEASURES SHALL BE PERMANENTLY STABILIZED TO PREVENT FURTHER EROSION AND SEDIMENTATION.

PERSON RESPONSIBLE FOR POLLUTION PREVENTION PRACTICES The qualified personnel, contractor listed below, will be responsible for the implementation and maintenance of the pollutant control measures. This may include delegating this responsibility to other contractors as they become involved with the project and begin the anticipated pollutant generating activity. They are required to hold weekly toolbox meetings to review the pollution prevention plan with their team. COMPANY NAME: PANTOPS SHOPPING CENTER, LLC CONTACT NAME: CHARLES ROTGIN, JR QUALIFICATION: PHONE NUMBER: 434-296-4141 EMAIL: crotgin@gemc.com QAULIFIED INSPECTOR/CONTRACTOR COMPANY NAME: CONTACT NAME: QUALIFICATION: PHONE NUMBER: EMAIL: QAULIFIED SUBCONTRACTOR/CONSTRUCTION MANAGER COMPANY NAME: CONTACT NAME: QUALIFICATION: PHONE NUMBER: EMAIL: B. POLLUTION PREVENTION AWARENESS DEQ's Office of Pollution Prevention hosts numerous programs and initiatives that serve as a conduit for non -regulatory assistance to businesses and communities. The contractor will ensure that their team is trained and knowledgably aware of all measures in this document before construction begins. Contractor shall conduct a "walk through" of the site with their team identifying areas of possible pollution and discussing how they will implement the prevention practices outlined in this report and shown on the plans. They are required to hold weekly toolbox meetings with their team to review the pollution prevention plan and give any updates on changes through the construction phase. C. SPILL PREVENTION AND RESPONSES The first priority is to protect all people, secondly protect the equipment and property, and lastly protect the environment. The contractor shall regularly check the equipment on site and any pollutants shall be stored properly to prevent spills. Spills will be immediately and promptly cleaned up by the contractor. Most spills can be cleaned up following manufacturer specifications. Absorbent/oil dry, sealable containers, plastic bags, and shovels/brooms are suggested minimum spill response items that should be available at this location. The following steps shall be taken in the case of a spill: 1. Check for hazards (flammable material, noxious fumes, cause of spill) — if flammable liquid, turn off engines and nearby electrical equipment. If serious hazards are present leave the area and call 911. Large spills are likely to present a hazard. 2. Make sure the spill area is safe to enter and that it does not pose an immediate threat to health or safety of any person. 3. Stop the spill source (most spills can be cleaned up following manufacturer specifications — absorbent/oil dry, sealable containers, plastic bags, and shovels/brooms are suggested minimum spill response items) 4. Call co-workers and supervisor for assistance and to make them aware of the spill and potential dangers. 5. If possible, stop spill from entering drains (use absorbent or other material if necessary). 6. Stop spill from spreading (use absorbent or other material if necessary). 7. If spilled material has entered a storm sewer; contact locality's storm water department. 8. Clean up spilled material according to manufacturer specifications, for liquid spills use absorbent materials and do not flush area with water. 9. Properly dispose of cleaning materials and used absorbent material according to manufacturer specifications. The following agency should be considered for notification in the case of a spill: Albemarle County Fire Rescue: 434-296-5833 Albemarle County Police Department: 434-296-5807 Virginia Department of Health: 434-972-6259 Virginia Department of Conservation & Recreation: 1-804-786-2094 Virginia Department of Environmental Quality: 1-540-574-7824 Virginia Department of Emergency Services: 1-800-468-8892 D.

These items shall be contained while on site in the designated washout area shown on the plans and covered at the end of each workday and before precipitation events. Pollution Prevention Practices: (1) Clearing, grading, excavating and un-stabilized areas — Utilize erosion and sediment controls to prevent sediment laden or turbid runoff from leaving the construction site. Dispose of clearing debris at acceptable disposal sites. Apply permanent or temporary stabilization, sodding and/or mulching to denuded areas in accordance with the erosion and sediment control specifications and the general VPDES permit for discharges of stormwater from construction activities. (2) Paving operations —Cover storm drain inlets during paving operations and utilize pollution prevention materials such as drip pans and absorbent/oil dry for all paving machines to limit leaks and spills of paving materials and fluids. (3) Concrete washout and cement waste — Direct concrete wash water into a leak -proof container or leak -proof settling basin that is 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. Washout areas shall be placed in an area that isn't susceptible to stormwater runoff and shall be covered at the end of each workday and before any rain events. (4) Structure construction, stucco, painting, and cleaning — Enclose, cover or berm building material storage areas if susceptible to contaminated stormwater runoff. Conduct painting operations consistent with local air quality and OSHA regulations. Mix paint indoors, in a containment area or in a flat unpaved area. Prevent the discharge of soaps, solvents, detergents, and wash water from construction materials, including the clean-up of stucco paint, form release oils and curing compounds by doing so in a contained area and collecting the discharged pollutants in a leak proof container that can be disposed of in the dumpster on site. Equipment and other tools may be washed in the concrete washout area. (5) Dewatering operations — Construction site dewatering from building footings or other sources may not be discharged without treatment. Sediment laden or turbid water shall be filtered, settled, or similarly treated prior to discharge. (6) Material delivery and storage — Designate areas of the construction site for material delivery and storage. Place near construction entrances, away from waterways, and avoid transport near drainage paths or waterways. (7) Material use during building process — Use materials only where and when needed to complete the construction activity. Follow manufacturer's instructions regarding uses, protective equipment, ventilation, flammability and mixing of chemicals. (8) Solid waste disposal — Designate a waste collection area on the construction site that does not receive a substantial amount of runoff from upland areas and does not drain directly to a waterway. Ensure that containers have lids so they can be covered at the end of each day and during periods of rain and keep containers in a covered area whenever possible. Schedule waste collection to prevent the containers from overfilling. (9) Sanitary waste — Prevent the discharge of sanitary waste by providing convenient and well - maintained portable sanitary facilities. Locate sanitary facilities in a convenient location away from waterways. (10) Landscaping operations— Maintain as much existing vegetation as practicable. Apply permanent or temporary stabilization, sodding and/or mulching to denuded areas in accordance with the erosion and sediment control specifications and the general VPDES permit for discharges of stormwater from construction activities. Apply nutrients in accordance with manufacturer's recommendations and not during rainfall events. (11) Others— E.

Measures taken to prevent the reoccurrence of any prohibited discharge; and g. Measures taken to address any evidence identified as a result of an inspection required under Part II G. 5. Amendments, modifications, or updates to the SWPPP shall be signed in accordance with Part III K. D. Public notification. Upon commencement of land disturbance, the operator shall post conspicuously a copy of the notice of coverage letter near the main entrance of the construction activity. For linear projects, the operator shall post the notice of coverage letter at a publicly accessible location near an active part of the construction project (e.g., where a pipeline crosses a public road). The operator shall maintain the posted information until termination of general permit coverage as specified in Part I F. E. SWPPP availability. 1. Operators with day-to-day operational control over SWPPP implementation shall have a copy of the SWPPP available at a central location on -site for use by those identified as having responsibilities under the SWPPP whenever they are on the construction site. Page 13 of 26 The operator shall make the SWPPP and all amendments, modifications, and updates available upon request to the department, the VSMP authority, the EPA, the VESCP authority, local government officials, or the operator of a municipal separate storm sewer system receiving discharges from the construction activity. If an on -site location is unavailable to store the SWPPP when no personnel are present, notice of the SWPPP's location shall be posted near the main entrance of the construction site. The operator shall make the SWPPP available for public review in an electronic format or in hard copy. Information for public access to the SWPPP shall be posted and maintained in accordance with Part II D. If not provided electronically, public access to the SWPPP may be arranged upon request at a time and at a publicly accessible location convenient to the operator or his designee but shall be no less than once per month and shall be during normal business hours. Information not required to be contained within the SWPPP by this general permit is not required to be released. F. SWPPP implementation. The operator shall implement the SWPPP and subsequent amendments, modifications, and updates from commencement of land disturbance until termination of general permit coverage as specified in Part I F. All control measures shall be properly maintained in effective operating condition in accordance with good engineering practices and, where applicable, manufacturer specifications. If a site inspection required by Part II G identifies a control measure that is not operating effectively, corrective actions shall be completed as soon as practicable, but no later than seven days after discovery or a longer period as established by the VSMP authority, to maintain the continued effectiveness of the control measures. If site inspections required by Part II G identify an existing control measure that needs to be modified or if an additional or alternative control measure is necessary for any reason, implementation shall be completed prior to the next anticipated measurable storm event. If implementation prior to the next anticipated measurable storm event is impracticable, then additional or alternative control measures shall be implemented as soon as practicable, but no later than seven days after discovery or a longer period as established by the VSMP authority. G. SWPPP Inspections. 1. Personnel responsible for on -site and off -site inspections. Inspections required by this general permit shall be conducted by the qualified personnel identified by the operator in the SWPPP. The operator is responsible for ensuring that the qualified personnel conduct the inspection. 2. Inspection schedule. a. For construction activities that discharge to a surface water identified in Part 11 B 5 and B 6 as impaired or having an approved TMDL or Part I B 7 as exceptional, the following inspection schedule requirements apply: (1) Inspections shall be conducted at a frequency of (i) at least once every four business days or (ii) at least once every five business days and no later than 24 hours following a measurable storm event. In the event that a measurable storm event occurs when Page 14 of 26 there are more than 24 hours between business days, the inspection shall be conducted on the next business day; and (2) Representative inspections as authorized in Part II G 2 d shall not be allowed. b. Except as specified in Part II G 2 a, inspections shall be conducted at a frequency of: (1) At least once every five business days; or (2) At least once every 10 business days and no later than 24 hours following a measurable storm event. In the event that a measurable storm event occurs when there are more than 24 hours between business days, the inspection shall be conducted on the next business day. c. Where areas have been temporarily stabilized or land -disturbing activities will be suspended due to continuous frozen ground conditions and stormwater discharges are unlikely, the inspection frequency described in Part II G 2 a and 2 b may be reduced to once per month. If weather conditions (such as above freezing temperatures or rain or snow events) make discharges likely, the operator shall immediately resume the regular inspection frequency. d. Except as prohibited in Part II G 2 a (2), representative inspections may be utilized for utility line installation, pipeline construction, or other similar linear construction activities provided that: (1) Temporary or permanent soil stabilization has been installed and vehicle access may compromise the temporary or permanent soil stabilization and potentially cause additional land disturbance increasing the potential for erosion; (2) Inspections occur on the same frequency as other construction activities; (3) Control measures are inspected along the construction site 0.25 miles above and below each access point (i.e., where a roadway, undisturbed right-of-way, or other similar feature intersects the construction activity and access does not compromise temporary or permanent soil stabilization); and (4) Inspection locations are provided in the inspection report required by Part II G. e. If adverse weather causes the safety of the inspection personnel to be in jeopardy, the inspection may be delayed until the next business day on which it is safe to perform the inspection. Any time inspections are delayed due to adverse weather conditions, evidence of the adverse weather conditions shall be included in the SWPPP with the dates of occurrence. 3. Inspection requirements. a. As part of the inspection, the qualified personnel shall: (1) Record the date and time of the inspection and, when applicable, the date and rainfall amount of the last measurable storm event; Page 15 of 26 (2) Record the information and a description of any discharges occurring at the time of the inspection or evidence of discharges occurring prior to the inspection; (3) Record any land -disturbing activities that have occurred outside of the approved erosion and sediment control plan; (4) Inspect the following for installation in accordance with the approved erosion and sediment control plan, identification of any maintenance needs, and evaluation of effectiveness in minimizing sediment discharge, including whether the control has been inappropriately or incorrectly used: (a) All perimeter erosion and sediment controls, such as silt fence; (b) Soil stockpiles, when applicable, and borrow areas for stabilization or sediment trapping measures; (c) Completed earthen structures, such as dams, dikes, ditches, and diversions for stabilization and effective impoundment or flow control; (d) Cut and fill slopes; (e) Sediment basins and traps, sediment barriers, and other measures installed to control sediment discharge from stormwater; (f) Temporary or permanent channels, flumes, or other slope drain structures installed to convey concentrated runoff down cut and fill slopes; (g) Storm inlets that have been made operational to ensure that sediment laden stormwater does not enter without first being filtered or similarly treated; and (h) Construction vehicle access routes that intersect or access paved or public roads for minimizing sediment tracking; (5) Inspect areas that have reached final grade or that will remain dormant for more than 14 days to ensure: (a) Initiation of stabilization activities have occurred immediately, as defined in 9VAC25-880-1; and (b) Stabilization activities have been completed within seven days of reaching grade or stopping work; (6) Inspect for evidence that the approved erosion and sediment control plan, "agreement in lieu of a plan," or erosion and sediment control plan prepared in accordance with department -approved annual standards and specifications has not been properly implemented. This includes: Page 16 of 26 (a) Concentrated flows of stormwater in conveyances such as rills, rivulets, or channels that have not been filtered, settled, or similarly treated prior to discharge, or evidence thereof; (b) Sediment laden or turbid flows of stormwater that have not been filtered or settled to remove sediments prior to discharge; (c) Sediment deposition in areas that drain to unprotected stormwater inlets or catch basins that discharge to surface waters. Inlets and catch basins with failing sediment controls due to improper installation, lack of maintenance, or inadequate design are considered unprotected; (d) Sediment deposition on any property (including public and private streets) outside of the construction activity covered by this general permit; (e) Required stabilization has not been initiated or completed or is not effective on portions of the site; (f) Sediment basins without adequate wet or dry storage volume or sediment basins that allow the discharge of stormwater from below the surface of the wet storage portion of the basin; (g) Sediment traps without adequate wet or dry storage or sediment traps that allow the discharge of stormwater from below the surface of the wet storage portion of the trap; and (h) Land disturbance or sediment deposition outside of the approved area to be disturbed; (7) Inspect pollutant generating activities identified in the pollution prevention plan for the proper implementation, maintenance, and effectiveness of the procedures and practices; (8) Identify any pollutant generating activities not identified in the pollution prevention plan; and (9) Identify and document the presence of any evidence of the discharge of pollutants prohibited by this general permit. 4. Inspection report. Each inspection report shall include the following items: a. The date and time of the inspection and, when applicable, the date and rainfall amount of the last measurable storm event; b. Summarized findings of the inspection; c. The locations of prohibited discharges; d. The locations of control measures that require maintenance; Page 17 of 26 e. The locations of control measures that failed to operate as designed or proved inadequate or inappropriate for a particular location; f. The locations where any evidence identified under Part II G 3 a (6) exists; g. The locations where any additional control measure is needed; h. A list of corrective actions required (including any changes to the SWPPP that are necessary) as a result of the inspection or to maintain permit compliance; i. Documentation of any corrective actions required from a previous inspection that have not been implemented; and The date and signature of the qualified personnel and the operator or its duly authorized representative. 5. The inspection report shall be included into the SWPPP no later than four business days after the inspection is complete. 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.

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 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.
