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 PROCEDURES 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.

A written report of the unauthorized discharge shall be submitted to the DEQ and the VSMP authority within 5 days of discovery of the discharge, and contain the information listed in Part III G (Reports of unauthorized discharges) of the Permit. Spill notification procedures will be reviewed by all key personnel during the Project Training/Permit Rollout process. A Spill Report Form is provided at the end of this section. 6.5.2 Reports of Unusual or Extraordinary Discharges If any unusual or extraordinary discharge, including a "bypass" or "upset" as defined in the 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 DEQ and the VSMP authority by telephone after the discovery of the discharge. This notification shall provide 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 DEQ and the VSMP authority within 5 days of discovery of the discharge in accordance with Part III I.2 of the Permit. Unusual and extraordinary discharges include, but are not limited to, any discharge resulting from: a. Unusual spillage of materials resulting directly or indirectly from processing operations; b. Breakdown of processing or accessory equipment; c. Failure or taking out of service of some or all of the facilities; and d. Flooding or other acts of nature. 6.5.3 Reports of Noncompliance The operator shall report any noncompliance that may adversely affect surface waters or endanger public health. • An oral report to the DEQ and the VSMP authority shall be provided within 24 hours from the time the operator becomes aware of the circumstances. The oral report shall contain the information specified in Part III I.1 of the Permit. • A written report shall be submitted within 5 days and shall contain the information specified in Part III I.2 of the Permit. The DEQ may waive the written report on a case - by -case basis for reports of noncompliance under Part III I (Reports of Noncompliance) of the Permit if the oral report has been received within 24 hours and no adverse impact on surface waters has been reported. • The operator shall report instances of noncompliance not reported under Part III I.1 or I.2 of the Permit in writing as part of the SWPPP. The reports shall contain the information listed in Part III 1.2 of the Permit. • 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 DEQ or the VSMP authority, the operator shall promptly submit such facts or correct information. NOTE: The reports required in Parts III G (Reports of Unauthorized Discharges), H (Reports of Unusual or Extraordinary Discharges), and I (Reports of Noncompliance) of the CGP shall be made to the DEQ and the VSMP authority.

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. 6.9 WASHING OF CONCRETE OR OTHER MATERIALS • 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 h!Ltp://www.epa.goy/npdes/pubs/concretewashout.12df (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.

During the period beginning with the date of coverage under this general permit and lasting until the general permit's expiration date, the operator is authorized to discharge stormwater from construction activities. 2. This general permit also authorizes stormwater discharges from support activities (e.g., concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated material disposal areas, borrow areas) located on -site or off -site provided that: a. The support activity is directly related to the construction activity that is required to have general permit coverage for discharges of stormwater from construction activities; b. The support activity is not a commercial operation, nor does it serve multiple unrelated construction activities by different operators; c. The support activity does not operate beyond the completion of the last construction activity it supports; d. The support activity is identified in the registration statement at the time of general permit coverage; e. Appropriate control measures are identified in a stormwater pollution prevention plan and implemented to address the discharges from the support activity areas; and f. All applicable state, federal, and local approvals are obtained for the support activity. B. Limitations on coverage. 1. Post -construction discharges. This general permit does not authorize stormwater discharges that originate from the site after construction activities have been completed and the site, including any support activity sites covered under the general permit registration, has undergone final stabilization. Post -construction industrial stormwater discharges may need to be covered by a separate VPDES permit. 2. Discharges mixed with nonstormwater. This general permit does not authorize discharges that are mixed with sources of nonstormwater, other than those discharges that are identified in Part I E (Authorized nonstormwater discharges) and are in compliance with this general permit. 3. Discharges covered by another state permit. This general permit does not authorize discharges of stormwater from construction activities that have been covered under an individual permit or required to obtain coverage under an alternative general permit. 4. Impaired waters and TMDL limitation. Discharges of stormwater from construction activities to surface waters identified as impaired in the 2012 § 305(b)/303(d) Water Quality Assessment Integrated Report or for which a TMDL wasteload allocation has been established and approved prior to the term of this general permit for (i) sediment or a sediment -related parameter (i.e., total suspended solids or turbidity) or (ii) nutrients (i.e., nitrogen or phosphorus) are not eligible for coverage under this general permit unless the operator develops, implements, and maintains a SWPPP that minimizes the pollutants of concern and, when applicable, is consistent with the assumptions and requirements of the approved TMDL wasteload allocations. In addition, the operator shall implement the following items: General Permit No.: VAR10 Page 2 of 23 a. The impaired water(s), approved TMDL(s), and pollutant(s) of concern, when applicable, shall be identified in the SWPPP; b.

Upon receipt, a copy of the notice of coverage under the general VPDES permit for discharges of stormwater from construction activities (i.e., notice of coverage letter); c. Upon receipt, a copy of the general VPDES permit for discharges of stormwater from construction activities; d. A narrative description of the nature of the construction activity, including the function of the project (e.g., low density residential, shopping mall, highway, etc.); e. A legible site plan identifying: (1) Directions of stormwater flow and approximate slopes anticipated after major grading activities; (2) Limits of land disturbance including steep slopes and natural buffers around surface waters that will not be disturbed; (3) Locations of major structural and nonstructural control measures, including sediment basins and traps, perimeter dikes, sediment barriers, and other measures intended to filter, settle, or similarly treat sediment, that will be installed between disturbed areas and the undisturbed vegetated areas in order to increase sediment removal and maximize stormwater infiltration; (4) Locations of surface waters; General Permit No.: VAR10 Page 6 of 23 (5) Locations where concentrated stormwater is discharged; (6) Locations of support activities, when applicable and when required by the VSMP authority, including but not limited to (i) areas where equipment and vehicle washing, wheel wash water, and other wash water is to occur; (ii) storage areas for chemicals such as acids, fuels, fertilizers, and other lawn care chemicals; (iii) concrete wash out areas; (iv) vehicle fueling and maintenance areas; (v) sanitary waste facilities, including those temporarily placed on the construction site; and (vi) construction waste storage; and (7) When applicable, the location of the on -site rain gauge or the methodology established in consultation with the VSMP authority used to identify measurable storm events for inspection purposes. 2. Erosion and sediment control plan. a. An erosion and sediment control plan approved by the VESCP authority as authorized under the Erosion and Sediment Control Regulations (9VAC25-840), an "agreement in lieu of a plan" as defined in 9VAC25-840-10 from the VESCP authority, or an erosion and sediment control plan prepared in accordance with annual standards and specifications approved by the department. Any operator proposing a new stormwater discharge from construction activities that is not required to obtain erosion and sediment control plan approval from a VESCP authority or does not adopt department -approved annual standards and specifications shall submit the erosion and sediment control plan to the department for review and approval. b. All erosion and sediment control plans shall include a statement describing the maintenance responsibilities required for the erosion and sediment controls used. c. A properly implemented 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, adequately: (1) Controls the volume and velocity of stormwater runoff within the site to minimize soil erosion; (2) Controls stormwater discharges, including peak flow rates and total stormwater volume, to minimize erosion at outlets and to minimize downstream channel and stream bank erosion; (3) Minimizes the amount of soil exposed during the construction activity; (4) Minimizes the disturbance of steep slopes; (5) Minimizes sediment discharges from the site in a manner that addresses (i) the amount, frequency, intensity, and duration of precipitation; (ii) the nature of resulting stormwater runoff; and (iii) soil characteristics, including the range of soil particle sizes present on the site; (6) Provides and maintains natural buffers around surface waters, directs stormwater to vegetated areas to increase sediment removal, and maximizes stormwater infiltration, unless infeasible; (7) Minimizes soil compaction and, unless infeasible, preserves topsoil; (8) Ensures that stabilization of disturbed areas will be initiated immediately whenever any clearing, grading, excavating, or other land -disturbing activities have permanently ceased on any portion of the site, or temporarily ceased on any portion of the site and will not resume for a period exceeding 14 days; and General Permit No.: VAR10 Page 7 of 23 (9) Utilizes outlet structures that withdraw stormwater from the surface (i.e., above the permanent pool or wet storage water surface elevation), unless infeasible, when discharging from sediment basins or sediment traps. 3. Stormwater management plan. a. New construction activities. A stormwater management plan approved by the VSMP authority as authorized under the Virginia Stormwater Management Program (VSMP) Regulation (9VAC25- 870), or an "agreement in lieu of a stormwater management plan" as defined in 9VAC25-870-10 from the VSMP authority, or a stormwater management plan prepared in accordance with annual standards and specifications approved by the department. Any operator proposing a new stormwater discharge from construction activities that is not required to obtain stormwater management plan approval from a VSMP authority or does not adopt department -approved annual standards and specifications shall submit the stormwater management plan to the department for review and approval. b. Existing construction activities. Any operator that was authorized to discharge under the general permit issued in 2009, and that intends to continue coverage under this general permit, shall ensure compliance with the requirements of 9VAC25-870-93 through 9VAC25-870-99 of the VSMP Regulation, including but not limited to the water quality and quantity requirements. The SWPPP shall include a description of, and all necessary calculations supporting, all post - construction stormwater management measures that will be installed prior to the completion of the construction process to control pollutants in stormwater discharges after construction operations have been completed. Structural measures should be placed on upland soils to the degree possible. Such measures must be designed and installed in accordance with applicable VESCP authority, VSMP authority, state, and federal requirements, and any necessary permits must be obtained. 4. Pollution prevention plan. A pollution prevention plan that addresses potential pollutant -generating activities that may reasonably be expected to affect the quality of stormwater discharges from the construction activity, including any support activity. The pollution prevention plan shall: a. Identify the potential pollutant -generating activities and the pollutant that is expected to be exposed to stormwater; b. Describe the location where the potential pollutant -generating activities will occur, or if identified on the site plan, reference the site plan; c. Identify all nonstormwater discharges, as authorized in Part I E of this general permit, that are or will be commingled with stormwater discharges from the construction activity, including any applicable support activity; d. Identify the person responsible for implementing the pollution prevention practice or practices for each pollutant -generating activity (if other than the person listed as the qualified personnel); e. Describe the pollution prevention practices and procedures that will be implemented to: (1) Prevent and respond to leaks, spills, and other releases including (i) procedures for expeditiously stopping, containing, and cleaning up spills, leaks, and other releases; and (ii) procedures for reporting leaks, spills, and other releases in accordance with Part III G; (2) 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); General Permit No.: VAR10 Page 8 of 23 (3) 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 (e.g., providing (i) cover (e.g., plastic sheeting or temporary roofs) to prevent contact with stormwater; (ii) collection and proper disposal in a manner to prevent contact with stormwater; and (iii) a similarly effective means designed to prevent discharge of these pollutants); (4) 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 or conveyance and directing wash waters to sediment basins or traps, using filtration devices such as filter bags or sand filters, or using similarly effective controls); (5) Direct concrete wash water into a leak -proof container or leak -proof settling basin.

Inspections shall be conducted at a frequency of: General Permit No.: VAR10 Page 11 of 23 (1) At least once every five business days; or (2) At least once every 10 business days and no later than 48 hours following a measurable storm event. In the event that a measurable storm event occurs when there are more than 48 hours between business days, the inspection shall be conducted no later than the next business day. b. 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 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. c. 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 report required by Part II F. 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; (2) Record the information and a description of any discharges occurring at the time of 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; General Permit No.: VAR10 Page 12 of 23 (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 channel, flume, 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 roads for minimizing sediment tracking; (5) Inspect areas that have reached final grade or that will remain dormant for more than 14 days for initiation of stabilization activities; (6) Inspect areas that have reached final grade or that will remain dormant for more than 14 days for completion of stabilization activities within seven days of reaching grade or stopping work; (7) 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 but is not limited to: (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 sediments 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 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 outside of the approved area to be disturbed; (8) Inspect pollutant generating activities identified in the pollution prevention plan for the proper implementation, maintenance and effectiveness of the procedures and practices; (9) Identify any pollutant generating activities not identified in the pollution prevention plan; and General Permit No.: VAR10 Page 13 of 23 (10) 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 location(s) of prohibited discharges; d. The location(s) of control measures that require maintenance; e.

The date and signature of the qualified personnel and the operator or its duly authorized representative. The inspection report and any actions taken in accordance with Part II must 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. G. Corrective actions. 1. The operator shall implement the corrective action(s) 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. 2. 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.

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 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, etc. 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 General Permit No.: VAR10 Page 18 of 23 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 must 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 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 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 90 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. General Permit No.: VAR10 Page 19 of 23 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. 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. General Permit No.: VAR10 Page 20 of 23 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. 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(s) of the upset; b. The permitted facility was at the time being properly operated; c. The operator submitted notice of the upset as required in 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 must be kept under the conditions of this general permit; 2. Have access to and copy, at reasonable times, any records that must 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. 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. General Permit No.: VAR10 Page 21 of 23 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 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. 2. 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. General Permit No.: VAR10 Page 22 of 23 DEFINITIONS "Business day" means Monday through Friday excluding state holidays. "Commencement of land disturbance" means the initial disturbance of soils associated with clearing, grading, or excavating activities or other construction activities (e.g., stockpiling of fill material). "Construction site" means the land where any land -disturbing activity is physically located or conducted, including any adjacent land used or preserved in connection with the land -disturbing activity. "Final stabilization" means that one of the following situations has occurred: 1. All soil disturbing activities at the site have been completed and a permanent vegetative cover has been established on denuded areas not otherwise permanently stabilized. Permanent vegetation shall not be considered established until a ground cover is achieved that is uniform (e.g., evenly distributed), mature enough to survive, and will inhibit erosion. 2. For individual lots in residential construction, final stabilization can occur by either: a. The homebuilder completing final stabilization as specified in subdivision 1 of this definition; or b. The homebuilder establishing temporary soil stabilization, including perimeter controls for an individual lot prior to occupation of the home by the homeowner, and informing the homeowner of the need for, and benefits of, final stabilization. 3. For construction projects on land used for agricultural purposes, final stabilization may be accomplished by returning the disturbed land to its preconstruction agricultural use. Areas disturbed that were not previously used for agricultural activities, such as buffer strips immediately adjacent to surface waters, and areas that are not being returned to their preconstruction agricultural use must meet the final stabilization criteria specified in subdivision 1 or 2 of this definition. "Immediately" means as soon as practicable, but no later than the end of the next business day, following the day when the land -disturbing activities have temporarily or permanently ceased. In the context of this general permit, "immediately" is used to define the deadline for initiating stabilization measures. "Impaired waters" means surface waters identified as impaired on the 2012 § 305(b)/303(d) Water Quality Assessment Integrated Report. "Infeasible" means not technologically possible or not economically practicable and achievable in light of best industry practices. "Initiation of stabilization activities" means: 1. Prepping the soil for vegetative or nonvegetative stabilization; 2. Applying mulch or other nonvegetative product to the exposed area; 3. Seeding or planting the exposed area; 4. Starting any of the above activities on a portion of the area to be stabilized, but not on the entire area; or 5. Finalizing arrangements to have the stabilization product fully installed in compliance with the applicable deadline for completing stabilization. This list is not exhaustive. General Permit No.: VAR10 Page 23 of 23 "Measurable storm event" means a rainfall event producing 0.25 inches of rain or greater over 24 hours. "Stabilized" means land that has been treated to withstand normal exposure to natural forces without incurring erosion damage. Section 12. Inspection logs (Provide templates for your inspections.
