Name of Receiving Waters: DEQ staff has determined that the proposed land-disturbing activity will discharge to a surface water identified as impaired or for which a TMDL wasteload allocation has been established and approved prior to the term of the general permit for(i) sediment or a sediment-related parameter or(ii)nutrients. Therefore,the following general permit(Part I.B.4) and SWPPP requirements (Part II.A.5)must be implemented for the land- disturbing activity: • Permanent or temporary soil stabilization shall be applied to denuded areas within seven(7) days after final grade is reached on any portion of the site. • Nutrients (e.g. fertilizers) shall be applied in accordance with manufacturer's recommendations or an approved nutrient management plan and shall not be applied during rainfall events. • Inspections shall be conducted at a frequency of(i) at least once every four(4) business days or(ii)at least once every five (5)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 on the next business day. • Representative inspections used by utility line installation, pipeline construction, or other similar linear construction activities shall inspect all outfalls. Special Conditions Related to TMDLs: Albemarle County is in the process of developing action plans for the Chesapeake Bay TMDL and for two local TMDLs having a wasteload allocation and approved by the Virginia Soil and Water Conservation Board. TMDLs pollutants of concern Approval date Chesapeake Bay phosphorus, nitrogen, N/A and sediment Rivanna River mainstem, North Fork of the Rivanna e. Coli bacteria 1/5/2009 River, Meadow Creek, and Beaver Creek Rivanna River benthic/sediment 6/11/2008 Above sources have been identified in the Albemarle County MS4 Program Plan(2013- 2018) dated October of 2014. Endangered and Threatened Species and Critical Habitat Protection The United States Fish& Wildlife Service has identified species that are believed to or known to occur in Virginia. The list can be found on their Environmental Conservation Online System at: http://ecos.fws.gov/ecp0/reports/species-listed-by-state-report?state=V A&status=listed There are no known endangered or threatened species located within the Timberwood Square at this time. Erosion and Sediment Controls Approved erosion and sediment control plans for Timberwood Square are incorporated by reference as part of this Stormwater Pollution Prevention Plan. Approved plans are included in this SWPPP binder. Stabilization Practices: 1. The purpose of the erosion control measures shown on these plans shall be to preclude the transport of all waterborne sediments resulting from construction activities from entering onto adjacent properties of state waters. If field inspection reveals the inadequacy of the plan to confine sediment to the project site, appropriate modifications will be made to correct any plan deficiencies. In addition to these notes, all provisions of the Virginia Erosion and Sediment Control Regulations shall apply to this project. 2. All erosion and sediment control measures shall be installed and maintained in accordance with the Virginia Erosion and sediment Control Handbook (3`d Edition, 1992) and Virginia Regulations VR 625-02-00 Erosion and Sediment control Regulations. The contractor shall be thoroughly familiar with all applicable measures contained therein which may be pertinent to this project. 3. All points of construction ingress and egress shall be protected by a temporary paved construction entrance, with a wash rack,to prevent tracking of mud onto public right-of-ways. An entrance permit from VDOT is required prior to any construction activities within state right-of-ways. Where sediment is transported onto a public road surface, the road shall be thoroughly cleaned at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. This provision shall apply to individual subdivision lots as well as to larger land disturbing activities. 4. The Albemarle County Department of Community Development schedules the pre-construction meeting;therefore,the developer,project engineer, or contractor must contact the Albemarle County Department of Community Development in order to schedule a preconstruction meeting. The preconstruction meeting shall be held at the Albemarle County Office Building between the County,the developer,the project engineer,and the contactor prior to issuance of the land disturbing permit. The contractor shall submit a sequence of construction to the County for approval prior to the preconstruction meeting. The contractor will supply code compliance with the name of the individual who will be responsible for any maintenance of installed measures that is required. The SWPPP Inspector will be in contact with this person to ensure that the necessary maintenance of the installed measures is taking place on a daily basis. The Albemarle County Department of Community Development must be notified one week prior to the preconstruction conference, one week prior to the commencement of land disturbing activity, and one week prior to the final inspection. 5. A copy of the approved erosion and sediment control plan shall be maintained on the site at all times. 6. Sediment basins and traps,perimeter dikes, sediment barriers, and other measures intended to trap sediment onsite must be constructed as a first step in grading and be made functional before upsiope land disturbance takes place. Earthen structures such as dams, dikes, and diversions must be seeded and mulched immediately after installation. Periodic inspections of the erosion control measures shall be made to assess their condition. Any necessary maintenance of the measures shall be accomplished immediately upon notification by the SWPPP Inspector and shall include the repair of measures damaged by any subcontractor including those of the public utility companies. 7. The contractor is responsible for installation of any additional erosion control measures necessary to prevent erosion and sedimentation as determined by the plan approving authority. 8. All disturbed areas are to drain to approved sediment control measures at all times during all land disturbing activities and during site development until final stabilization is achieved. 9. Sediment control measures may require minor field adjustments at time of construction to insure their intended purpose is accomplished. Division of code compliance approval will be required for other deviations from the approved plans. 10. Surface flows over cut and fill slopes shall be controlled by either redirecting flows from traversing slopes or by installing mechanical devices to safely lower water down slope without causing erosion. A temporary fill diversion(std. and spec. 3.10) shall be installed prior to the end of each working day. 11. During dewatering operations,water will be pumped into an approved filtering device. 12. The contractor shall place soil stockpiles at the locations shown on the SWPPP plan sheet for each area of construction, or as directed by design engineer. Soil stockpiles shall be stabilized or protected with sediment trapping measures. Offsite waste or borrow areas shall be approved by the division of code compliance prior to the import of any borrow or export of any waste to or from the project. 13. Prior to commencing land disturbing activities in areas other than indicated on these plans(including, but not limited to, offsite borrow or waste areas),the contractor shall submit a supplementary erosion control plan to the owner for review and approval by the plan approving authority. 14. The contactor shall complete drainage facilities within 30 days following completion of rough grading at any point within the project. The installation of drainage facilities shall take precedence over all underground utilities. Outfall ditches from drainage structures shall be stabilized immediately after construction of same. This includes installation of erosion control stone or paved ditches where required. Any drainage outfalls required for a street must be completed before street grading or utility installation begins. 15. Permanent or temporary soil stabilization must be applied to all denuded areas within 7 days after final grade is reached on any portion of the site. Soil stabilization must also be applied to denuded areas which may be a final grade but will remain dormant(undisturbed)for longer than 14 days. Soil stabilization measures include vegetative establishment, mulching and the early application of gravel base material on areas to be paved. 16. No more than 300 feet of sanitary storm sewer, waterlines,or underground utility lines are to be immediately stabilized(i.e.,the same day). 17. If disturbed area stabilization is to be accomplished during the months of November, December,January or February, stabilization shall be accomplished by permanently seeding the area with a seeding mixture that includes the seasonal nurse crop for the Piedmont area, which is Winter Rye. See Table 3.32-D for a list of site specific seeding mixtures for the Piedmont area. This is in accordance with Specification 3.32 from the Virginia Erosion and Sediment Control Handbook(VESCH). The seeding area will also need to be,mulched in order to assist the growth of the seeding in the winter months(Specification 3.35 of the VESCH).For temporary seeding stabilization during these months, a 50/50 mix of annual ryegrass and winter ryegrass, as well as a mulching cover should be put down according to Specification 3.31 of the VESCH, Table 3.31-B. 18. The term seeding, final vegetative cover or stabilization, on this plan shall mean the successful germination and establishment of a stable grass cover from a properly prepared seedbed containing the specified amounts of seed, lime, and fertilizing in accordance with Specification 3.32,permanent seeding. Irrigation shall be required as necessary to ensure establishment of grass cover. 19. All slopes steeper than 3:1 shall require the use of erosion control blankets such as Excelsior blankets to aid in the establishment of a vegetative cover that is hardier than grass. Matting or mulch matting may also be used on recently planted slopes in order to protect the seeding until the vegetative cover becomes established on the slopes. Installation shall be in accordance with Specification 3.35, mulching and manufacturer's instructions. No slopes shall be created steeper than 2:1. 20. Inlet protection in accordance with Specification 3.07 shall be provided for all storm drain inlets as soon as practical following construction of same. 21. Paved ditches shall be required wherever erosion is evident. Particular attention shall be paid to those areas where grades exceed 33 percent. Temporary liners, such as polyethylene sheets, shall be provided for all paved ditches until the permanent concrete liner is installed. 22. 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 disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sedimentation. 23. As-built drawings must be provided for all detention/BMP facilities. Also upon completion,the construction of all detention/BMP facilities shall be certified by a professional engineer who inspected the structure during construction. The certification shall state that to the best of his/her judgment,knowledge, and belief,the structure was constructed in accordance with the approval plans and specifications. Structural Practices: The following erosion and sediment control structural practices will be incorporated on the project sites: 1. Temporary Construction Entrance 8. Inlet Protection 2. Safety Fence 9. Dust Control 3. Super/Silt Fence 10. Outlet Protection 4. Temporary Diversion Dikes 11. Safety Fence 5. Temporary Sediment Trap 12. Temporary Seeding 6. Temporary Sediment Basin 13. Mulching 7. Stormwater Conveyance Channel 14. Turbidity Curtain Stormwater Management: A. Any land-disturbing activity shall be considered grandfathered by the VSMP authority and shall be subject to the Part II C (9VAC25-870-93 et seq.)technical criteria of this chapter provided: 1. A proffered or conditional zoning plan,zoning with a plan of development, preliminary or final subdivision plat,preliminary or final site plan, or any document determined by the locality to be equivalent thereto (i) was approved by the locality prior to July 1, 2012, (ii)provided a layout as defined in 9VAC25-870-10, (iii) will comply with the Part II C technical criteria of this chapter, and(iv)has not been subsequently modified or amended in a manner resulting in an increase in the amount of phosphorus leaving each point of discharge, and such that there is no increase in the volume or rate of runoff; 2. A state permit has not been issued prior to July 1, 2014; and 3. Land disturbance did not commence prior to July 1,2014. A preliminary plan was approved prior to Julyl, 2012. There is an increase in the impervious areas for this development plan compared to the preliminary plan,therefore a biofilter will be used to remove the difference in phophorous and water quantity that the extra impervious area creates. An existing wet pond facility known as"Arbor Lake"will be utilized to provide stormwater quantity measures for the 2yr and l0yr storm events. The remaining stormwater quality will utilize offsite phosphorous credits. Details for stormwater management for the project are provided in the"Stormwater Management Plans"attached with this document. I 1 SH Op m VSMP PLAN FOR °��4 `'�c • (WP0201900015) N 07 onHo u.

SHEET 140F14 Pollution Prevention Plan Inventory for Pollution Prevention Plan: The materials or substances listed below are expected to be present onsite during construction: -Concrete -Petroleum based products •Wood -Solvents -Masonry block •Insulation -Roofing shingles •Paints -Tar -Fertilizers -Vinyl siding -Herbicides Spill Prevention Plan: Inventory of Exposed Materials: The materials or substances listed below may be present onsite and have the potential to be exposed to precipitation: -Concrete -Petroleum based products -Wood -Solvents -Masonry block -Detergents -Roofing shingles -Paints -Tar -Fertilizers -Vinyl siding •Herbicides •Insulation Material Management Practices: The following are the materials management practices that will be used to reduce the risk of spills or other accidental exposure of materials and substances to stormwater runoff. Employee Training: Employee training with regard to material management practices is conducted at the site. Training includes discussions of spill response, good housekeeping, and other material management practices. Employee training generally occurs with each new employee once hired. Good Housekeeping: The following good housekeeping practices will be followed onsite during the construction project. • All materials stored onsite will be stored in a neat, orderly manner in their appropriate containers. Materials which have the potential for contaminating runoff during storm events will be stored in their appropriate watertight containers, stored under a canopy,tarpaulin, shrink wrapped or otherwise precluded from direct exposure of precipitation. • Empty containers that may contain chemical residues shall be disposed of in accordance with State and local regulations. • Products, where possible, will be kept in their original containers with the original manufacture's label. • Chemical or petroleum products will not be mixed with one another unless recommended by the manufacturer. • Whenever possible, all of a product will be used up before disposing of the container. • Manufacturer's recommendations for proper use and disposal will be followed. • The site superintendent will inspect daily to ensure proper use and disposal of materials onsite. Hazardous Products: These practices are used to reduce the risk associated with hazardous materials. • Products will be kept in original containers unless they are not resealable. • Original specimen labels and materials safety data sheets will be kept on file; they contain important product information. • If surplus product must be disposed of, manufacturers and/or local and State recommended methods for proper disposal will be followed. Material Safety Data Sheets (MSDS) will be available for all chemical materials used onsite and will be located with the SWPPP binder on site. Product Specific Practices: The following product specific practices will be followed onsite: Petroleum Products: • All onsite vehicles will be monitored for fluid leaks and will receive regular preventive maintenance to reduce the chance of leakage. • It is recommended that, if practicable, all refueling, repair and changing of equipment and vehicle fluids shall be conducted in a designated area, with the use of either spill buckets and/or fuel spill mats to reduce the potential for contamination. This area will be designed in a manner to reduce the potential for contamination of onsite resources. For refueling, repair and changing of equipment and vehicle fluids outside of the designated areas, care should be taken to avoid activities within+/- 50 feet of wetlands, streams, water bodies, tree preservation areas or any other environmentally sensitive areas. • Petroleum products will be stored in tightly sealed containers which are clearly labeled. • An area will be designated for the collection and storage of all chemical and storage of all chemical and petroleum based products and containers for those products. The containers shall be protected from rain events. These areas are identified on the SWPPP/PPP Reference Drawing included with the "Final Construction.Plans"for each block. • Any asphalt substances used onsite will be applied according to the manufacturer's recommendations. • • The project superintendent will regularly inspect the site to insure proper disposal methods of used antifreeze, oils, filters and other hazardous materials are followed. Fertilizers: Fertilizers used will be applied according to manufacturer's product standards. The contents of any partially used bags of fertilizer will be transferred to a sealable plastic container to avoid spills. Paints: All containers will be tightly sealed and stored when not required for use. Excess paint will be properly disposed of according to manufacturers' instructions or State and local regulations. Concrete Trucks: Concrete trucks will only wash out or discharge surplus concrete or drum wash water at approved locations in accordance with State and local regulations. These areas are identified on the SWPPP/PPP Reference Drawing included with the"Final Construction Plans". Spills and Leaks: This section normally contains a list of significant spills and significant leaks of toxic or hazardous pollutants that occurred at areas that are exposed to precipitation or that otherwise drain to a stormwater conveyance at the facility within the 3 year period immediately prior to the date of submission of a registration statement to be covered under this permit. However, since the project location is still proposed and not constructed,therefore not in operation at the proposed location,no significant spills and/or leaks have occurred at the site of toxic or hazardous pollutants at areas that are exposed to precipitation. Spill control Practices: In addition to the good housekeeping and material management practices discussed in the previous sections of this plan,the following practices will be followed for spill prevention and cleanup: • Manufacturers' recommended methods for spill cleanup will be clearly posted and site personnel will be made aware of the procedures and the location of the information and cleanup supplies. • Materials and equipment necessary for spill cleanup will be kept in the material storage area onsite. Equipment and materials may include but not be limited to brooms, dust pans,mops,rags, gloves, goggles, absorbent material (e.g. kitty litter, sand, sawdust)and plastic and metal trash containers. • All spills will be cleaned up immediately after discovery. • In the event of a spill of a hazardous substance,the spill will be immediately contained and the spill area will be kept well ventilated. Personnel will wear appropriate protective clothing to prevent injury form contact with a hazardous substance during cleanup operation. • Spills of toxic or hazardous material will be reported to the appropriate State or local government agency, as required by regulatory standards. Call the agencies listed below to report any spills of toxic or hazardous material: VDEQ Valley Regional Office: M-F, 8:30-4:30 540-574-7800 VDEM:Nights,holidays, and weekends 1-800-468-8892 Local VSMP Authority: M-F, 8:00-5:00 434-296-5832 Good Housekeeping BMPS Waste Materials: All waste materials will be collected and stored in a proper receptacle in accordance with all local and State solid waste management regulations. All trash and construction debris from the site will be deposited in dumpsters. The trash will be hauled to an appropriate waste disposal site. No construction waste materials will be buried onsite. All project personnel will be instructed regarding the correct procedure for waste disposal. Hazardous Waste: All 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. Sanitary Waste: All sanitary waste will be collected from the portable units as required by local and State regulation. Offsite Vehicle Tracking: Stabilized construction entrances will be provided to help reduce vehicle tracking of sediments. The paved street adjacent to the site entrance will be swept as needed to remove any excess mud,dirt or rock tracked from the site. Dump trucks hauling material from the construction site will be covered with a tarpaulin. Timing of Controls and Measures: As indicated in the Stabilization Practices,permanent or temporary soil stabilization must be applied to all denuded areas within 7 days after final grade is reached on any portion of the site. Soil stabilization must also be applied to denuded areas which may not be a final grade but will remain dormant(undisturbed)for longer than 30 days. Soil stabilization measures include vegetative establishment,mulching and the early application of gravel base material on areas to be paved. Certification of Compliance with Federal, State and Local Requirements: The Stormwater Pollution Prevention Plan reflects State requirements for stormwater management and erosion and sediment control,as established in the Virginia Stormwater Management Handbook and Virginia Erosion and Sediment Control Manual. Maintenance and Inspection Procedures Erosion and Sediment Control Inspection and Maintenance Practices: Inspections of the construction site shall be made by the SWPPP Inspector,Nicole Jamison, or by other qualified members of the Pollution Prevention Team(Jim Taggart, David Robinson). Erosion and sediment control measures identified in the plan shall be observed to ensure that they are still operating correctly. The contractor shall inspect all erosion control measures at least once every 4 or 5 business days and after each significant rainfall producing event. Any necessary repairs or cleanup to maintain the effectiveness of the erosion control devices shall be made within seven(7)days. Inspections shall be conducted(i)at least once every four(4)business days or(ii)at least once every five (5)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 on the next business day. These inspections shall cover disturbed areas that have not been finally stabilized, areas used for storage of materials that are exposed to precipitation, structural control measures,and locations where vehicles enter or exit the site. Where areas have been finally or temporarily stabilized or runoff is unlikely due to winter conditions(e.g. site is covered with snow, ice or frozen ground exists) such inspections shall be conducted at least one every month. Reports summarizing each inspection shall be retained onsite as part of this Stormwater Pollution Prevention Plan. Comprehensive Site Compliance Evaluation—Post Construction: Facility inspections will be conducted at least once a year by qualified personnel. The inspections will assess conditions at the facility that could impact stormwater quality and to assess the effectiveness of the BMPs that were constructed to control the quality of the stormwater discharges. Non-Stormwater Discharges: It is expected that the following non-stormwater discharges will occur from the site during the construction period. 1. Waters used to wash vehicles or equipment where soaps, solvents, or detergents have not been used and the wash water has been filtered, settled, or similarly treated prior to discharge. 2. Water used to control dust that has been filtered, settled, or similarly treated prior to discharge. 3. Potable water sources, including uncontaminated waterline flushings. 4. Routine external building wash down where soaps, solvents or detergents have not been used and the wash water has been filtered, settled, or similarly treated prior to discharge. 5. Pavement wash waters where spills or leaks of toxic or hazardous materials have not occurred (or where all spilled or leaked material has been removed prior to washing); where soaps, solvents, or detergents have not been used; and where the wash water has been filtered, settled, or similarly treated prior to discharge. 6. Foundation or footing drains where flows are not contaminated with process materials such as solvents. 7. Uncontaminated excavation dewatering, including dewatering of trenches and excavations that have been filtered, settled, or similarly treated prior to discharge. 8. Landscape irrigation. All non-stormwater discharges will be directed to sediment basins prior to discharge. r -\ NOTE: FUEL STORAGE TANKS TO USE SECONDARY CONTAINMENT PALLETS WITH SPILL KITS READILY AVAILABLE. c\,,,I,„ , _ __\y , 77 rj-=',„ ri \ .. `. \ \,,, \\ \ 1 3Q iaRO I I / // / Crry / e / 1 , I r „--- / / ,/ / ij , I /,..A / / / / / i , / ' 1 ',, 4!\ \\ ±1, i i SF i — _ _ / I i / I / / I / ,// ` / 1 \` / // j / // /i / 6x�4��ii // // `/ ki t cc \/ ,...- 7 00"C" // //6 J ` // \ .,. \ \ : // p� vGc\,.P. z' / �� /�' z / ` \ \ J 0 ± i / \ /( iti / �4�GOac��PS`j` /8p'�' 5�� INSTALLS PIPE I `� - -24, - J- ( AI . 1 / \ QRO NHS �� E /' ,��\P, --- e �� ,RUN 1-1 A-2-3—ELFf / SY I / 1 f� G ��G i* S /i / S.�oR� .4,/ AND PROVIDE IM f / �o " / .�.

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 II 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 16of26 (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.

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. 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.
