Nature of activity 1 i I.,\ ,`,.ice .t e .,t :h l�._ .i�:?::ll�\ i' yrF\ iL��.� l:�z`I.:`� of `,C.heLluic and This SWPPP has been developed in accordance with the requirements contained in the Virginia Pollution Discharge Elimination System(VPDES) storm water general permit for discharges from construction activities (9 VAC 25-880). It is the responsibility of the Operator involved with grading, drainage, utilities or who implement a pollutant control measure 0111110 identified in the Storm Water Pollution Prevention Plan(SWPPP)to secure authority to discharge stormwater from land disturbing activates of one acre or greater in full conformance with the stormwater regulations of the Virginia Department of Environmental Quality(VDEQ) as contained in 9 VAC 25-880. The Operator and all subcontractors must comply with ear the requirements of the VSMP as contained in the VDEQ VPDES storm water general permit and implementing regulations (9 VAC 25-880) and the erosion and sediment control requirements of the VDEQ as published in the Virginia wl Erosion and Sediment Control Handbook(current edition). These requirements are as follows: A. The Operator will file a complete Registration Statement for coverage under a VPDES General Permit for storm water discharges from construction activities with the Virginia Department of ... Environmental Quality at least 15 days prior to commencement of construction. Verification of coverage received from the Department of Environmental Quality prior to the commencement of land 8111 disturbing activities exceeding the thresholds noted above. The appropriate filing fee (as outlined in local ordinance in VSMP localities or as outlined below for non-VSMP localities) in check form made out to "Treasurer of the locality in which the project is occurring except for localities not collecting permit fees (by ordinance or those choosing not to be VSMP Authorities), " (for non-VSMP Authority localities, make checks payable to "Treasurer of Virginia") must be submitted to the locality or DEQ for non-VSMP Authority localities before the general permit will be issued. The fees, payable by the Operator, are as follows: • Less than 1 acre(only areas within common plans of development or sale): $290 • Between 1 and 5 acres: $2,700 • Between 5 and 10 acres: $3,400 • Between 10 and 50 acres: $4,500 • Between 50 and 100 acres: $6,100 000 • Greater than 100 acres: $9,600 Send the Permit Fee form and check for the appropriate fee amount to the following address: Department of Environmental Quality Receipts Control P.O.

Box 1105 Richmond, Virginia 23218 B. A copy of the Registration Statement for coverage under the general permit for storm water discharges from construction activities as well as the actual general permit when issued by the VDEQ shall be maintained by the Operator for inspection at the construction site. Land disturbing activities cannot commence until verification of coverage is received by the Operator from VDEQ. C. A complete copy of the SWPPP, including copies of all inspection reports,plan revisions, etc., must be ises retained by the Operator at the project site at all times during working hours and kept in the Operator's permanent project records for at least three years following submission of the Notice of Termination (NOT). wit D. The Operator must provide names and addresses of all subcontractors working on this project who will be involved with all construction activities that disturb site soil. This information must be kept with this SWPPP. E. The Operator and all subcontractors involved with land disturbing for this project must sign a copy of the appropriate certification statement included in Appendix C which will be incorporated into the construction contract. F. As described below, the Operator shall conduct regular inspections to determine effectiveness of the SWPPP. The SWPPP shall be modified by the Operator as needed to prevent pollutants from discharging from the site. The Operator's inspector must be both a person familiar with the site and the nature of the major construction activities and be qualified to evaluate both overall system performance and individual component performance. Additionally, the Operator's inspector must either be someone empowered to implement modifications to this SWPPP and the pollutant control devices, if needed, in order to increase effectiveness to an acceptable level, or someone with the authority to cause such things to happen. This �.. authority should be delegated to the inspector by using the enclosed Letter of Delegation of Authority (Appendix A) signed by the Operator naming the person or position responsible for undertaking these tasks on behalf of the Operator. G. This SWPPP shall be updated each time there are modifications to the pollutant prevention system or a change of Operators working on the project that disturbs site soil. The Operator shall notify the governing reviewing agency before these modifications are implemented, unless immediate Operator action is necessary to prevent unauthorized discharges. If immediate Operator action is needed, then the Operator shall notify the governing reviewing agency of the action as soon as practicable. H. Discharge of oil or other hazardous substances into the storm water is subject to reporting and cleanup requirements. Refer to Part III.G of the VPDES General Permit for additional information. Copies of the VPDES General Permit and the Registration Statement forms are available on the Department of Environmental Quality web site (http://www.deq.v ProQrams/Water/StormwaterManaaement/VSMPPeniiits.aspx). �. I. Once the site reaches final stabilization, the Operator shall complete and submit two copies of the NOT form for activities on site. This form is included as Appendix E. If a section or phase of the project reaches final stabilization prior to the entire project reaching final stabilization, then that section may be clearly marked on the site plans and the date of final stabilization recorded in the SWPPP. Areas so marked are no longer required to be inspected as a part of permit compliance. J. This SWPPP is intended to control water-borne and liquid pollutant discharges by some combination of interception, filtration, and containment. The Operator and all subcontractors implementing this SWPPP 6 •" shall remain alert to the need to periodically refine and update the SWPPP in order to accomplish the intended goals. K. This SWPPP shall be amended as necessary during the course of construction in order to keep it current with the pollutant control measures utilized at the site. Amending the SWPPP does not mean that it has to be reprinted. It is acceptable to handwrite revisions, add addenda, sketches, new sections, and/or revised drawings. L. A record of the dates when land disturbing activities occur, when construction activities temporarily or permanently cease on a portion of the site, and when stabilization measures are initiated shall be maintained by the Operator until the NOT is filed. A log for keeping such records is included in the Appendices. A different form for the log may be substituted if it is found to be more useful. M. Annual permit maintenance fees are required. Maintenance fees are as follows: • Less than 1 acre(only areas within common plans of development or sale): $50 • Between 1 and 5 acres: $400 • Between 5 and 10 acres: $500 • Between 10 and 50 acres: $650 • Between 50 and 100 acres: $900 • Greater than 100 acres: $1,400 " This SWPPP has been prepared for land disturbing activities associated with the construction of State Farm Boulevard and South Pantops Drive Sidewalk Project in Charlottesville, Virginia. There are three distinct phases to this project. Phase 1 consists of the area along State Farm Boulevard between station 29+63.52 and the intersection with US Route 250.Phase WM 2 consists of the area along South Pantops Drive between station 56+28.54 and station 61+05.43. Phase 3 consists of the area along State Farm Boulevard between the intersection with South Pantops Drive and station 29+63.52. Phase 3 also extends northwest along South Pantops Drive between the intersection with State Farm Boulevard and station 51+27.66. This SWPPP includes the elements necessary to comply with the Storm Water General Permit issued by the VDEQ under the VPDES and local governing agency requirements. This SWPPP shall be implemented at the start of construction. Without adequate control there is the potential for each type of pollutant to be transported by stormwater. The project will consist of the following basic activities: (mark appropriate activities) Z Site grading, ® Paving work, ® Installation of stormwater management and drainage systems, ® Installation of utilities, ❑ Other activities(specify) 7 *W Purpose A major goal of pollution prevention efforts during project construction is to control soil and pollutants that originate on the site and prevent them from flowing to surface waters of the Commonwealth. The purpose of this SWPPP is to provide .. requirements for achieving that goal. A successful pollution prevention program also relies upon careful inspection and adjustments during the construction process in order to enhance its effectiveness. 0. Scope This SWPPP must be implemented when land disturbing activities begin on the site. This SWPPP will be made available for public inspection upon public request on site during normal business hours for the term of the permit authorization for the site. The SWPPP Construction Site Notice as well as a copy of the DEQ Coverage Letter must be posted OW conspicuously and readable from a public right of way at the job site. This SWPPP primarily addresses the impact of storm rainfall and runoff on areas of the ground surface disturbed during ,,,,, the construction process. In addition, there are recommendations for controlling other sources of pollution that could accompany the major construction activities. Permit coverage is terminated as of the date the lot is transferred to a new owner, coverage under a new VPDES permit is obtained, or as of the date another Operator assumes control over portions of the site not stabilized. In these situations, coverage under the permit terminates at midnight the date the Notice of 40. Termination(NOT) is filed. Where the Operator seeks to terminate coverage because the site has reached final stabilization, termination will become effective upon concurrence by the VSMP Authority, or after 60 days from the submittal of the NOT, whichever occurs first. Forms required to implement the SWPPP are included in the Appendices to this document. The VPDES General Permit for Storm Water Discharges from Construction Activities prohibits most non-storm water •+ discharges during the construction phase. Allowable non-storm water discharges that may occur during construction on this project, which would therefore be covered by the General Permit, include: ... 1. Discharges from firefighting activities; 2. Fire hydrant flushing; INS 3. Water used to wash vehicles or control dust where detergents are not used; 4. Water flowing from potable sources and water line flushing; im 5. Water used to control dust; ""0 6. External building wash down which does not use detergents; 7. Runoff from pavement wash down where spills or leaks of toxic or hazardous materials have not occurred(unless all spilled material has been removed) and where detergents have not been used; 8. Uncontaminated air conditioning or compressor condensate; OM 9. Springs and uncontaminated groundwater; U• 10. Foundation or footing drains where flows are not contaminated with process materials such as solvents; .., 11. Uncontaminated excavation dewatering; and 12. Landscape irrigation. VIM The techniques described in this SWPPP focus on providing control of pollutant discharges with practical approaches that utilize readily available expertise,materials, and equipment. The Operator referred to in this SWPPP is the entity noted on the VSMP registration statement. The Operator and .. their subcontractor(s) will construct the site development improvements in accordance with the approved plans and this SWPPP. 8 Described below are the land disturbing construction activities that are the subject of this SWPPP. They are presented in .e• the order(or sequence)they are expected to begin, but each activity will not necessarily be completed before the next begins. Also, these activities could occur in a different order if necessary to maintain adequate erosion and sedimentation control: A.

Please refer to them for imp detailed site information. H. Site Location—The State Farm Boulevard and South Pantops Drive Sidewalk project will be located at 1500 State Farm Boulevard in Charlottesville, Virginia. There are three distinct phases to this project. M•• Phase 1 consists of the area along State Farm Boulevard between station 29+63.52 and the intersection with US Route 250. Phase 2 consists of the area along South Pantops Drive between station 56+28.54 and station 61+05.43. Phase 3 consists of the area along State Farm Boulevard between the intersection with South Pantops Drive and station 29+63.52. Phase 3 also extends northwest along South Pantops Drive between the intersection with State Farm Boulevard and station 51+27.66. I. Site Topography and Coverage—The site is next to the Pantops Shopping Center,just east of the Rivanna River. Current elevations range from 400 feet to 530 feet. Existing on-site vegetation includes grass, shrubs, and trees. Most of the site consists of impervious cover due to existing buildings, parking areas, and driveways. J. Rainfall Information—The average annual rainfall for Charlottesville, Virginia is 42.56. A rain gauge shall be installed on site to determine if an inspection triggering rainfall event has occurred. An inspection "triggering rainfall event" is rainfall that equals or exceeds one quarter inch (0.25") in a 24-hour period at the construction site. ... K. Site Soils—The following soils are present on-site according to a web soil survey generated from the United States Department of Agriculture(USDA) and Natural Resources Conservation Service (NRCS) online database: Soil Type 23B Davidson clay loam The Davidson component makes up 27 percent of the map unit. Slopes are 2 to 7 percent. This component is on hillslopes. The natural drainage class is well drained. The soil is not ponded and is not flooded. "" Soil Type 23C Davidson clay loam The Davidson component makes up 9 percent of the map unit. Slopes are 7 to 15 percent. This component is on hillslopes. The natural drainage class is well drained. The soil is not ponded and is not flooded. ... Soil Type 71C Raburn clay loam The Raburn component makes up 23 percent of the map unit. Slopes are 7 to 15 percent. This component is on interfluves. The natural drainage class is well drained. The soil is not ponded and is not flooded. Soil Type 23C """ Raburn clay loam 11 4..- The Raburn component makes up 41 percent of the map unit. Slopes are 15 to 25 percent. This component is on interfluves. The natural drainage class is well drained. The soil is not ponded and is not flooded. NM L. Total Area and Disturbed Area—The total land area of development is 2.24 acres. This includes 0.56 im acres in phase 1, 0.45 acres in phase 2, and 1.23 acres in phase 3. The total estimated disturbed area is 1.19 acres. This includes 0.12 acres in phase 1, 0.93 acres in phase 2, and 0.14 acres in phase 3. W. M. Quality of Receiving Surface Waters and/or Wetlands—The proposed drainage of the State Farm Boulevard and South Pantops Drive Sidewalk Project will ultimately drain in to the Rivanna River/ Meadow Creek. The Meadow Creek is classified as Waters of the United State. Meadow Creek is included on the Virginia Department of Environmental Quality 2012 305(b)/303(d) Water Quality Assessment Integrated Report as impaired for Recreation Use. Recreation Use is impaired due to exceedance of the instantaneous criteria for Escherichia coli. To offset these impairments during "'m construction portable sanitary facilities will be utilized on site and regularly serviced by contractor following competition of construction wastewater will be directed to existing public sanitary sewer system. N. Threatened or Endangered Species or their Critical Habitat—The Virginia Department of Game and Inland Fisheries' Virginia Fish and Wildlife Information Service was reviewed for the presence of threatened or endangered species on the site. Zero species were identified as threatened or endangered within three miles of the project area. Other potential endangered species within three miles of the project site are displayed in the chart below. Coordination with the proper federal, state, and local agencies should occur if these species are observed during construction or if impacts to these species' habitats will occur. MN 0. Erosion Control Plan—The Erosion and Sediment control facilities shown on the approved E&S Plans (Appendix G) include a stone construction entrance, silt fence, drop inlet protection, and culvert inlet .. protection. Permanent Stormwater Controls—Runoff from the developed portions of the study area will, where practical,be directed to the existing stormwater system. Stormwater quality and quantity calculations proving the adequacy of this best management practice for meeting regulatory requirements are provided in Appendix I. «r In addition to this SWPPP, construction activities associated with this project must comply with all additional Mill requirements set forth by the town of Charlottesville.

IA I :IC.0 lte` :tlil\ A variety of storm water pollutant controls (Best Management Practices) are recommended for this project. These controls are reflected in the Erosion and Sediment Control Plans enclosed herein as Appendix G. Some controls are "I intended to function temporarily and will be used as needed for pollutant control during the construction period. These include temporary sediment barriers such as silt fencing, a rock construction entrance, and inlet protection measures. For most disturbed areas, permanent stabilization will be accomplished by covering the soil with pavement, buildings, other imp improvements, and/or vegetation. AIM I. Erosion and Sediment Controls 1. Short and Long Term Goals—All erosion and sediment control measures have been selected, designed and are to be installed in accordance with the Virginia Erosion and Sediment ION Control Law and Regulations. The short term goal of construction phase stabilization is to minimize the loss of sediment to adjacent waters during construction. The long term goal is to minimize the loss of sediment from the project once constructed by permanent soil INN stabilization. 2. Soil Stabilization- The purpose of soil stabilization is to prevent soil from leaving the site. In the natural condition, soil is stabilized by existing vegetation. The primary technique to be used at this project for stabilizing site soil will be to provide a protective cover of turf grass,pavement, other improvements, or building over disturbed soil. (a) Temporary Seeding— Stabilization for all areas to remain denuded for a period of fourteen(14) days or longer(for disturbed area draining to impaired waters, Tier III waters or to waters with a TMDL established prior to the issuance of the Construction General Permit), or; thirty(30) days or longer(for all other disturbed areas) shall be initiated within twenty-four(24)hours after construction activity ceases in these areas. The methods for establishing stabilization shall be applied within seven(7) days of initiation. Temporary seeding shall be in conformance with the project plans and/or erosion and sediment control narrative. .MO (b) Permanent Seeding or Sodding- Stabilization for all areas at final grade shall be initiated within twenty-fours (24)hours of completion of the land disturbing activity. The methods for establishing final stabilization shall be applied within seven(7) days of initiation. Except for small level spots, seeded areas shall be protected with mulch. Permanent seeding or Sodding shall be in conformance with the project plans and/or erosion and sediment control narrative. WIN (c) Structural Controls—Storm water runoff is to be structurally controlled as depicted on the plan sheets and/or project narrative. Structural controls shall be keyed to land disturbing activities especially on sites with significant topography and shall be completely installed prior to commencement of such land disturbing activities. 0411. (d) Final Stabilization—Final stabilization is not considered established until a ground cover is achieved that is uniform, mature enough to survive and will inhibit erosion. The 13 IMP Operator shall stabilize all exposed earth areas with permanent vegetation as described in the project plans and/or erosion and sediment control narrative. f.. Int MN MO MO ..

Other aspects of this SWPPP are listed below: Dust Control - Construction traffic must enter and exit the site at the stabilized construction entrance. The purpose is to trap dust and mud that would otherwise be carried off-site by construction traffic. .« Dust control shall be provided by the Operator in compliance with applicable local and state dust control regulations. After construction, the site will be stabilized(as described elsewhere), which will reduce the potential for dust generation. Effluent from de-watering activities must be filtered or passed through an approved sediment trapping device, or both, before being discharged from the site. No contaminated effluent or groundwater may be discharged with stormwater without a separate VPDES discharge permit from the VDEQ. Such 111110 permit shall be obtained by the Operator,prior to discharge. Solid Waste Disposal -No solid materials, including building materials, are allowed to be discharged from ® the site with storm water. All solid waste, including disposable materials incidental to the major construction activities, must be collected, removed from the site and disposed of in a legal manner. The locations of solid waste containers must be shown on the site maps. Substances that have the potential for polluting surface water and/or groundwater must be controlled by whatever means necessary in order to ensure that they are not discharged from the site. As an example, special care must be exercised during equipment fueling and servicing operations. If a spill occurs, it must be contained and disposed of so that it will not flow from the site or enter groundwater, even if this requires removal, treatment, and disposal of soil. In this regard, potentially polluting substances should be handled in a manner consistent with the impact they represent. Sanitary Facilities -All personnel involved with construction activities must comply with state and local sanitary or septic system regulations. Temporary sanitary facilities where provided at the site throughout the construction phase must be utilized by all construction personnel and shall be serviced by a commercial operator when provided. Their location must be shown on the project site maps if installed on site. Water Source-Non-storm water components of site discharge must be clean water. Water used for construction, which discharges from the site, must originate from a public water supply or private well approved by the Virginia Department of Health. Water used for construction that does not originate from an approved public supply must not discharge from the site. It is to be retained in ponds until it infiltrates and evaporates. .r D. Construction Phase "Best Management Practices" During the construction phase, the Operator shall implement the following measures where appropriate: 1. Material resulting from clearing and grubbing shall be stockpiled up slope from adequate sedimentation controls or hauled off-site. All soil stockpile areas shall be annotated on the project plans in Appendix G. 16 MN INN 2. All soil stockpile areas shall be maintained sufficiently far from water bodies or wetlands and shall be adequately protected from erosion to preclude migration of sediments into the water bodies or wetlands. 3. The Operator shall designate areas for equipment cleaning, maintenance, and repair. The Operator and subcontractor(s) shall utilize those areas. The areas shall be protected by a temporary perimeter berm or silt fencing. INN 4. Use of detergents for large scale washing is prohibited(i.e., vehicles,buildings, pavement surfaces, etc.) 5. Chemicals, paints, solvents, fertilizers, and other toxic material must be stored in waterproof containers. Except during application,the contents must be kept locked in trucks or within .11 locked storage facilities. Runoff containing such material must be collected, removed from the site, treated, and disposed at an approved solid waste or chemical disposal facility. W.. 6. All materials used for concrete mixing shall be washed down in a designated area where the corresponding runoff is directed into a leak-proof container or leak-proof settling basin. This concrete wash water shall be properly disposed of off-site. MI MN MIN .. .. MON .. 11111 .. .. .. .. 17 .. B.

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. Based on these inspections, the Operator shall decide whether it is necessary to modify this SWPPP, add or relocate sediment barriers, or institute other actions required in order to prevent pollutants from leaving the site via storm water runoff. The Operator has the duty to repair, modify, maintain, or supplement pollutant control measures and take other MIR actions necessary to achieve effective pollutant control The Operator may install a rain gauge at the site to determine site specific rainfall conditions or must provide estimates of rainfall at the project site and provide information as to how the estimates were generated. For purposes of permit compliance, it is strongly recommended that the Operator install a rain gauge at the project site. Examples of particular items to be evaluated during site inspections are listed below. This list is not intended to be comprehensive. During each inspection, the Operator's inspectors must evaluate overall pollutant control system performance, as well as the effectiveness of system components. Additional factors should be considered as appropriate to the circumstances. E. Locations where vehicles enter and exit the site must be inspected for evidence of off-site sediment tracking. A stabilized construction entrance will be constructed where vehicles enter and exit. This entrance will be maintained or supplemented as necessary to prevent sediment from leaving the site on vehicles. Sediment tracked onto public roadways must be shoveled or swept from the roadway and re- deposited on site in a manner that minimizes its offsite release potential. B. Sediment barriers must be inspected and, if necessary, they must be enlarged or cleaned in order to provide additional capacity. All material excavated from behind sediment barriers shall be stockpiled on the up slope side of the barrier. Additional sediment barriers must be constructed as needed. Sediment MINNmust be removed from sediment traps and sediment basins when the design capacity has been reduced by 50%. C. Inspections will evaluate disturbed areas and areas used for storing materials that are exposed to rainfall for evidence of, or the potential for, pollutants entering the drainage system. If necessary, the materials must be covered or original covers must be repaired or supplemented. Also, protective berms must be constructed, if needed, in order to contain runoff from material storage areas. Grassed areas will be inspected to confirm that a healthy stand of grass is maintained. The site has achieved final stabilization when turf grass cover provides permanent stabilization of the soil surface exclusive of areas that have been paved or covered by building(s). Permanent stabilization is not considered established until a ground cover is achieved that is uniform, mature enough to survive and will inhibit erosion. 21 r. D. All discharge points must be inspected to determine whether erosion control measures are effective in preventing impacts to receiving waters. Based on inspection results, any modification necessary to increase effectiveness of this SWPPP to an acceptable level shall be made by the Operator within seven calendar days of the inspection. All modifications to the SWPPP document and approved plan will be noted on the construction plans. The inspection reports must be completed entirely and additional remarks shall be included if needed to fully describe a situation. An important aspect of the inspection report is the description of additional measures that need to be taken to enhance plan effectiveness. The inspection report must gm identify whether the site was in compliance with the SWPPP at the time of inspection and specifically identify all Qom incidents of non-compliance. Inspection reports will be kept on file by the Operator as an integral part of this SWPPP for at least thirty six months following the month the Notice of Termination is filed with the VDEQ. It is the responsibility of the Operator to ensure the adequacy of site storm water pollutant discharge controls. Physical site conditions, weather conditions or Operator practices may make it necessary to install more structural controls than are shown on the plans. (For example, localized concentrations of runoff could make it necessary to install additional sediment barriers.) Assessing the need for additional controls and implementing them or adjusting existing controls are key aspects of the effectiveness of this SWPPP until the site achieves final stabilization. Should a control fail, be r bypassed or otherwise be ineffective in maintaining sediments onsite and releasing sediment offsite the Operator will r provide notification to the VDEQ in accordance with Part III. G. of the VPDES Storm Water General Permit, as necessary. If it is determined by the Operator's Inspector that there has been an upset or bypass of the control measures resulting in a release of sediment to State waters, the Operator's Inspector shall report the bypass or upset to the Valley Regional Office of the Virginia Department of Environmental Quality(VDEQ) at 540-574-7800 within 24 hours of discovery of the unanticipated bypass or upset. Within five days of making the verbal report to VDEQ, a written report shall be submitted by the Operator containing: • A description of the nature and location of the discharge; • The cause of the discharge; • The date on which the discharge occurred; • The length of time that the discharge continued; • The volume of the discharge; 22 • If the discharge is continuing, how long it is expected to continue; • If the discharge is continuing, what the expected total volume of the discharge will be; and Any steps planned or taken to reduce, eliminate and prevent a recurrence of the present discharge or any future discharges not authorized by this general permit. iw 111111 NMI dal 23 1100 111111 SITE STABILIZATION and CONSTRUCTION ACTIVITY DATES .. A record of dates when land disturbing activities occur, when construction activities temporarily or permanently cease on a portion of the site, and when stabilization measures are initiated shall be maintained by the Operator until final site stabilization is achieved and the Notice of Termination is filed.

Water Quality Calculations DRAINAGE Project Description The State Farm Boulevard and South Pantops Sidewalk Project consists of approximately 3,200 LF of sidewalk and roadway improvements along State Farm Boulevard (SR 1117) between South Pantops Drive and Richmond Road (US Route 250) and along South Pantops Drive (SR 1140) from just north of State Farm Boulevard to just south of the entrance to the Carriage Hill Apartments. These improvements in Pantops, VA will provide better pedestrian access and storm water infrastructure. Pantops, Virginia is located across the Rivanna River from Downtown Charlottesville, VA. Description of Existing Drainage Conditions The section of State Farm Boulevard between South Pantops Drive and Hickman Road is surrounded by open grassy fields, low lying brush and large canopy trees. State Farm Boulevard from between Hickman Road and Richmond Road (US Route 250) is bounded by developed property consisting of buildings and asphalt parking lots, which drain to off-site storm water management systems. There is a high point along State Farm Boulevard, near station 31+50 that impacts this project. The runoff that collects down station from 31+50 either sheet flows to off-site storm water managements systems, sheet flows into the ravine that leads to the Rivanna River, or is collected in roadside ditches and is conveyed to an existing off-site drainage easement to the south of State Farm Boulevard (Please see the description of the impacts of the Martha Jefferson Project below). The runoff that collects up station `r from 31+50 is conveyed to a storm drainage system at the intersection of State Farm Boulevard and Richmond Road. South Pantops Drive is surrounded by undeveloped grassy and forested lands to the east and fully developed properties to the west. Run-off along South Pantops Drive and the undeveloped areas to the east is collected via roadside ditches and either conveyed to a grate inlet near station 58+00 then to an off-site storm water management system or it is conveyed to the ravine which crosses beneath South Pantops Drive in route to the Rivanna River. The site drains to four (4) main outfall points (Appendix B): ■ Outfall#1 (Analysis Point #1) - An existing storm drainage system located in the northwest quadrant of the State Farm Boulevard and Richmond �- Road intersection. The existing storm drainage system carries run-off away from the project to the north. The existing drop inlet, which collects run-off from Sate Farm Boulevard and the intersection will be connected to structure 105-1 and converted to a manhole. • Outfall#2 (Analysis Point #2)—An existing off-site storm drainage Page 2 of 7 conveyance system near the intersection of State Farm Boulevard and South Pantops Drive. A series of roadside ditches and a grate inlet along the north side of State Farm Boulevard conveys run-off from the undeveloped properties to the north beneath the roadway, as well as the roadway median and a portion of the EBL of State Farm Boulevard. The system outfalls into an existing off-site storm drainage system (Please see the description of the Martha Jefferson Hospital Project below). The proposed State Farm Boulevard drainage system will be connected to the existing grate inlet and storm drainage system in the median of State Farm Boulevard. m„ ■ Outfall#3 (Analysis Point #3)—located along South Pantops Drive approximately 800' northwest of the intersection with State Farm Boulevard. It is an existing roadway cross-culvert that outfalls into a MIS concrete ditch than runs north along South Pantops Drive eventually into a larger swale and eventually into the Rivanna River. The culvert will be integrated into a proposed storm-sewer system. wr • Outfall#4 (Analysis Point #4) — located along South Pantops Drive located at the northern limits of the projects. This is where the proposed curb and gutter ties to the existing concrete curb and gutter and downstream conveyance system. Adjacent Areas The site is bordered by the State Farm Insurance Agency Complex to the west, Richmond Road (US Route 250) to the east, the Martha Jefferson Hospital to the south and the "m Carriage Hill Apartments to the north. Soil Description According to the Natural Resource Conservation service map the soils on site are all loam variations. Critical Areas • Ravine which leads to the Rivanna River. • Rivanna River. -- • Construction slopes throughout the site. Adjacent Projects Martha Jefferson Hospital/Peter Jefferson Parkway wor Construction is completed for the new home of the Martha Jefferson Hospital, which is located in the southeast quadrant of the South Pantops Drive and State Farm Boulevard intersection. South Pantops Drive was extended to the south to Page 3 of 7 create Peter Jefferson Parkway, which will serve as the access point for the proposed hospital. This construction impacts Outfall#3, which the proposed ."" changes are detailed below per the Peter Jefferson Parkway Plans (by others.) • The existing outfall pipe was extended beneath the proposed Peter Jefferson Parkway to enable run-off to be discharged into the off-site .. storm drainage easement, which will direct run-off to the Rivanna River. • The outfall was protected by outfall protection or VDOT Std. EC-1. 0. • The proposed and altered outfall pipes are denoted in Appendix F as pipes EX-1 to EX-2 and EX-2 to out. • Based on the information provided by the Peter Jefferson Parkway Plans .w these pipes are adequate for the proposed conditions. EROSION CONTROL Erosion and Sediment Control Measures VW • Inlet protection will be used at all existing and proposed storm sewer inlets to reduce the amount of sediment carried into the storm sewer systems. • Silt fence is used to reduce the sediment carried off site by sheet flow. 'r"" • Outlet protection is used to reduce erosion at pipe outlets. • Permanent and temporary stabilization - The site will be stabilized by the ultimate development including paved areas, seeded areas and landscaped areas. - Temporary stabilization will be used in accordance with MS-1. • Soil stockpiles and Borrow areas. 0. - Soil stock piles will be encircled with silt fence and temporary seeding will be performed if necessary. Construction Schedule •• A sequence of construction is provided in the E&S Control plan sheets (see Appendix C). Maintenance Schedule Erosion control measures will be inspected and maintained in accordance with the Virginia Erosion and Sediment Control Handbook (VESCH). MO PROPOSED DRAINAGE IMPROVEMENTS Overview MO The proposed onsite drainage design consists of a series of curb drop inlets and ,.. reinforced concrete pipes which collect runoff from the roadway. This proposed pipe Page 4 of 7 system routes stormwater runoff from the ground surface to the various outfall points along the project. See Description of Existing Conditions above for their descriptions. ... The drop-inlet throat openings were sized in QHEC12. The pre-development drainage area is shown on Plan Sheet CG-100 the post- WM development drainage areas are shown on Plan Sheet CG-101 (both in Appendix B). .. Methodology The proposed drainage system was designed to collect and convey the storm water runoff a,,,, for the 2-year and 10-year storms. Existing and proposed topography are shown on the proposed plan using 2' contours. Times of concentration for overland flow were calculated using the Seelye chart. Times of concentration for channel flow were .. calculated using the Kirpich chart. The curb inlet throat lengths were analyzed using Haestad Methods Flowmaster software to check the depth and spread during a storm event producing 4in/hr of rainfall intensity. Jaw The following is a summary of the drainage design parameters for the proposed development. ..

Page 5 of 7 IOW .w MS-19 COMPLIANCE OW Overview The analysis points described above in the Overview of Existing Drainage Conditions and as shown on the post-development drainage map included in Appendix B were analyzed for compliance with the MS-19 Standards set forth by the Erosion and Sediment Control Regulations. A summary of compliance calculations are included below. 41111 Analysis Point #1 is located on the at the State Farm Boulevard and Richmond Road OW intersection. It is an existing underground storm drainage system. This system currently drains a portion of the existing intersection and the modified portion of State Farm Boulevard (Drainage Area E5 in the existing condition and A3 and 105-1 in the proposed .. condition.) The calculations in Appendix D for storm pipe 105-1 to EX-20 will show that the system is adequate and very little if any impervious area is added to the existing system. Analysis Point #2 is located in the median near the State Farm Boulevard and South Pantops Drive intersection. It is an existing underground storm drainage system, which was modified by the Martha Jefferson Hospital Project. Although the pre vs. post drainage area increases in the post development, the downstream storm sewer system and outfall were improved to handle this project's increased flows to convey the stormwater `"' discharge to the Rivanna River. The design of the Martha Jefferson Hospital Project accounted for the additional run-off from the State Farm Boulevard Sidewalk project during design. OM Analysis Point#3 is located along South Pantops Drive northwest of the intersection with State Farm Boulevard. It is an existing roadway cross-culvert that outfalls into a concrete ditch than runs along South Pantops Drive eventually into a larger swale and eventually into the Rivanna River. The 15" culvert will be integrated into a proposed „M storm sewer system and is adequate to convey the increase in flow (7.35 cfs pre- development, 7.53 cfs post-development) due to a small increase in impervious area in its drainage area. The increased run-off of is approximately 0.18 cfs as deemed to be a illar negligible increase. Analysis Point#4 is located along South Pantops Drive northwest of the intersection with MINI State Farm Boulevard. It is the termination of the project where proposed curb and gutter connects with existing concrete curb and gutter and a downstream conveyance system. The applicable site area (A-Site) within the right-of-way draining to this analysis 'I point is 0.14 acres, which is less than 1% of the contributing drainage area of 24.76 acres. Page 6 of 7 MO CBPA COMPLIANCE This project is not located within the Chesapeake Bay Preservation Area (CBPA). The western limit of the CBPA is approximately Interstate 95. However, the project involves more than 10,000 square feet of land disturbance, so water quality requirements are applicable for coverage under a VSMP permit. Water Quality requirements are described in the Virginia Stormwater Management Handbook. This project utilized performance- based water quality calculations to perform the water quality analysis. The Applicable Area within this project's right-of-way is 2.24 acres. The pre- p. impervious area is 1.25 acres, meaning the pre-development impervious cover is 55.8%. This is greater than statewide average land cover condition of 16%, meaning this project falls under "Situation 3" and must reduce post-development pollutant runoff to 10% less than the pre-development pollutant runoff. The pre- development pollutant runoff load is 2.83 lb/yr, meaning post development pollutant runoff must be reduced to 1.00 lb/yr. With the post-development impervious area being pi. 1.60 acres, the post development pollutant runoff would be 3.54 lb/yr if no BMP is utilized. To reduce the post-development pollutant load then, a BMP(s) must be able to remove 1.00 lb/yr. The pollutant removal requirement of 1.00 lb/year will be purchased from a nutrient bank. Water quality calculations are presented in Appendix D. The following table details these water quality calculations. TOTAL IMP. PERVIOUS IMP. P LOAD RR SCENARIO AREA(AC.)

WSW ISO Preface Soil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many ism different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand,protect,or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions.The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses.The landowner or user is responsible for identifying and complying '"t with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://soils.usda.gov!sgi/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center(http://offices.sc.egov.usda.gov/locator/app? ... agency=nres) or your NRCS State Soil Scientist(http:!/soils.usda.gov/contact/ state_offices/). Great differences in soil properties can occur within short distances. Some soils are mo, seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads.Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Soil Data Mart Web site or the NRCS Web Soil Survey. The Soil Data Mart is the data storage site for the official soil survey information.

How Soil Surveys Are Made "O" Soil surveys are made to provide information about the soils and miscellaneous areas in a specific area.They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations �• affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage;the kinds of crops and native plants; and the kinds of bedrock.They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently,soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous MEW areas in the survey area and relating their position to specific segments of the landform,a soil scientist develops a concept,or model,of how they were formed.Thus, during mapping,this model enables the soil scientist to predict with a considerable ,r, degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their IMO characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock IMO fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). 'r" Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic •. classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil scientists classified and named the soils in the survey area, they compared the 5 'MI Custom Soil Resource Report MOO individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components;the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and °-� landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. `" Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping,design of map units, complexity of the landscape,and .. experience of the soil scientist. Observations are made to test and refine the soil- landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand,silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics �• and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are AIMmodified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and de" identified each as a specific map unit.Aerial photographs show trees, buildings,fields, roads, and rivers, all of which help in locating boundaries accurately. 6 Int OM OW OW Soil Map OM The soil map section includes the soil map for the defined area of interest,a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map.

Totals for Area of Interest 220.5 100.0% - rr Map Unit Descriptions The map units delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area. The map unit descriptions, along with the ... maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits forthe properties of the soils.On the landscape, however,the soils are natural phenomena, and they have the characteristic variability 10 rr '•" Custom Soil Resource Report of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes.Consequently,every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management.These are called contrasting,or dissimilar,components.They generally are in small areas and could not be mapped separately because of the scale used. _ Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area,the contrasting minor components are identified in the map unit descriptions along with some characteristics of each.A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition,thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such - differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps.The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and 11 Custom Soil Resource Report ,,,,. relative proportion of the soils or miscellaneous areas are somewhat similar.Alpha- Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them.Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material IMOand support little or no vegetation. Rock outcrop is an example.

For the purposes of this chapter: "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.

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 Page 26 of 29 9VAC25-880 (adopted 12117/2013 - published 2/24/2014 - effective 7/1/2014) essential maintenance to ensure efficient operation. These bypasses are not subject to the provisions of Part III U 2 and 3. 2. Notice. r- 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. 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; Page 27 of 29 9VAC25-880 (adopted 12/17/2013 - published 2/24/2014 - effective 7/1/2014) 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. 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.

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. 9VAC25-880-80.
