Nature of activity (Provide a detailed narrative of the construction activities. Include or reference a construction schedule and sequence. Include any phasing.) 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 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 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 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 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 • 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.

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 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). 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.deg.vir ig nia. og v/Proj rams/Water/StormwaterManagement/VSMPPermits.aWx). 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. This SWPPP is intended to control water -borne and liquid pollutant discharges by some Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County combination of interception, filtration, and containment. The Operator and all subcontractors implementing this SWPPP 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 "his SWPPP has been prepared for land disturbing activities associated with the construction of Barracks Road Route 654) in Albemarle County, VA. 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: ® Site grading, ® Paving work, ® Installation of stormwater management and drainage systems, ® Installation of utilities, ❑ Other activities 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. Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County Scope Nftw 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 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 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; 3. Water used to wash vehicles or control dust where detergents are not used; 4. Water flowing from potable sources and water line flushing; 5. Water used to control dust; 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; 9. Springs and uncontaminated groundwater; 10. Foundation or footing drains where flows are not contaminated with process materials such as solvents; 11. Uncontaminated excavation dewatering; and 12. Landscape irrigation. Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County The techniques described in this SWPPP focus on providing control of pollutant discharges with practical ,,.,,pproaches 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. Described below are the land disturbing construction activities that are the subject of this SWPPP. They are presented in 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: B. The proposed project involves construction of sidewalks and associated improvements along Barracks Road. This will include constructing a sidewalk (approximately 1,675 feet), crosswalks, and pedestrian signals from Barracks West apartments north side of Barracks Road to the existing sidewalk near the Georgetown Road intersection (referred to as Area 1) and constructing crosswalks and short sections sidewalk (where feasible) at strategic locations on the south side of Barracks Road near the intersection with Route 656 (Georgetown Road) referred to as Area 2. The total project area is 0.391 acres and the total proposed area of disturbance is 0.833 acres. C. Sequence of Construction Area 1 (C-502): 1. Install signs and other temporary traffic control (TTC) devices as shown in the traffic control plans (TCP). 2. Shift Traffic in the eastbound lane of Barracks Road by maintaining one lane at I I' wide. 3. Construct widening, curb and gutter, and sidewalk. Construction at entrances and intersections will require phasing to maintain access. 4. Contractor shall use TTC Figure 1 J to construct the improvements to the portion of Barracks Road where there is an adequate work zone clear zone provided. Where the work zone clear zone cannot be maintained, the contractor shall utilize a one-way flagging operation along Barracks Road. Contractor shall install a 6:1 wedge along the existing edge of pavement whenever the drop between the existing pavement and the subgrade is greater than two inches (2„). The contractor may be allowed to utilize a 4:1 wedge (minimum) should the 6:1 wedge not be feasible. The contractor shall maintain two lanes of traffic at the end of each work day with a minimum lane width of 11'. 5. Wedge pavement and overlay under a flagger operation in accordance with TTC 23.1. 6. Finish striping, signing and seeding and open roadway to improvements. Area 2 (C-503): 1. Install signs and other TTC devices as shown in the TCP's. 2. Clear and excavate sidewalk space behind existing curb with workers protected by an outside lane closure (during allowable lane closure times). 3. Construct radius improvements at side street connections. Note a flagging operation is required on side streets when insufficient room including the 8' clear zone is not available. 4. Pour sidewalk concrete behind existing curb with workers protected by an outside lane closure (during allowable lane closure times). 5. Place signs and striping. Place final seeding. Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County 6. Open improvements to pedestrian traffic. D. The project site consists of 0.391 acres with a disturbed area of 0.833 acres. E. The project drains to three outfalls — 1, 2, and 3. The pre -development runoff coefficient for Outfall 1 is 0.50. The runoff coefficient will be increased to 0.53 under post -development conditions. The pre -development runoff coefficient for Outfall 2 is 0.70 and will be increased to 0.76 under post -development conditions. The pre -development runoff coefficient for Outfall 3 is 0.58 and will remain at 0.58 under post -development conditions. F. Other potential sources of pollution — Vehicle fuels and lubricants. G. The ultimate downstream receiving water body for stormwater runoff for the proposed sidewalk improvements is JR07 (Ivy Creek -Little Ivy Creek) on the north side of Barracks Road and JRl4 (Rivanna River -Meadow Creek) on the south side. H. The selected erosion and sediment control drawings, grading and drainage drawings, and/or erosion and sediment control narrative provided in Section 4 and Section 5 illustrate/outline the following: 1. Drainage patterns and approximate slopes or contours anticipated after grading activities 2. Areas of soil disturbance and areas of the site which are not to be disturbed. 3. Location of major structural and non-structural controls. `%"` 4. Location of areas where stabilization practices are expected to occur including types of vegetative cover 5. Surface waters including wetlands 6. Locations where stormwater is discharged to a surface water with an outline of the drainage area for each discharge point. 7. Existing and planned paved areas and buildings 8. Location of permanent stormwater management practices to be used to control pollutants in stormwater after construction activities have been completed Location of all off -site materials, waste, borrow or equipment storage areas covered by the plan, and 10. Location of other potential sources of pollution The actual schedule for implementing pollutant control measures will be determined by project construction progress. Down slope protective measures must always be in place before soil is disturbed. Included as part of this SWPPP in Section 4 and Section 5 are selected project construction drawings. Please refer to them for detailed site information. im A. Site Location — The proposed project will be located along Barracks Road and is split into two areas. Area 1 will take place from the Barracks West apartments on the north side of Barracks Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County l Road to the existing sidewalk near the Georgetown Road intersection. Area 2 will take place at specific locations on the south side of Barracks Road near the intersection with Route 656 (Georgetown Road). The surrounding land uses in these areas are rural area and residential. The closest body of water is Little Ivy Creek. B. Site Topography and Coverage — On -site elevations range from approximately 530 feet to 630 feet. The site drains to existing storm sewers and an existing natural channel before being conveyed to Ivy Creek and the Rivanna River. While most of the site is impervious cover due to road coverage, parking areas, and existing driveways, existing vegetation includes trees, grass, and shrubs. C. Rainfall Information — The average annual rainfall for Charlottesville, Virginia is 42.56 inches (Monticello weather station, NOAA and NCDC). Fifty-six percent (24 inches) of the annual precipitation occurs between April and September. 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. D. 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 (MRCS) online database. Soil Tyne 2C: Albemarle fine sandy loam, 7 to 15 percent slopes The Albemarle component makes up 80 percent of the map unit. Slopes are 7 to 15 percent. This component is on hillslopes, piedmonts.

Total Area and Disturbed Area — The project site consists of 0.391 acres with a disturbed area of 0.833 acres. F. Quality of Receiving Surface Waters and / or Wetlands — The proposed drainage of Barracks Road (Route 654) will ultimately drain to either Ivy Creek — Little Ivy Creek or Rivanna River — Meadow Creek. Ivy Creek are classified as Waters of the United States and are included on the Virginia Department of Environmental Quality 2014 305(b)/303(d) Water Quality Assessment Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County M Integrated Report as impaired for Aquatic Life and Recreation Use. The Aquatic Life use is impaired based on exceedance of criteria for Benthics and pH. The Recreation Use is impaired based on exceedance of criteria for E. Coli. The Total Maximum Daily Load (TMDL) Waste Load Allocation (WLA) is scheduled to be developed for Benthics and pH by 2018 and for E. Coli by 2026. Meadow Creek is classified as Waters of the United States and is included on the Virginia Department of Environmental Quality 2014 305(b)/303(d) Water Quality Assessment Integrated Report as impaired for Aquatic Life and Recreation Use. The Aquatic Life use is impaired based on exceedance of Benthics and the Recreation use is impaired based on exceedance of E. Coli and Fecal Coliform. The TMDL WLA is scheduled to be developed by 2018 for Benthics and was scheduled to be developed by 2014 for E. Coli and Fecal Coliform. To offset these impairments during construction portable sanitary facilities will be utilized on site and regularly serviced by contractor. These sanitary facilities will also be offset from any stormwater inlet or access. G. 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. One species, the James Spinymussel (Pleurobema collina) was identified as threatened or endangered within two miles of the project area. Other potential endangered species in Albemarle County include the Northern Long -Eared Bat (Myotis septentrionalis), the Tri-Colored Bat (Perimyotis subf1avus), the Loggerhead Shrike (Lanius ludovicianus), the Atlantic Pigtoe (Fusconaia masoni) and the Green Floater (Lasmigona subviridis). 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. H. Erosion Control Plan — The Erosion and Sediment Control facilities shown on the approved E&S Plans (Section 4 and Section 5) include silt fencing, inlet protection, rock check dams, seeding, mulching, and rip rap as shown on Sheet 2B, 3B, 4B, and 5A. These plans are provided in Section 4. I. Permanent Stormwater Controls — Runoff from the proposed project area will be directed to proposed or existing drop inlets to a storm sewer system. Runoff at Outfall 1 will be detained in a proposed underground detention system in order to control quantity requirements for the project. This runoff will be released into an existing swale along Barracks Road. Runoff from Outfalls 2 and 3 will be released into existing storm sewer systems. Stormwater quality and quantity calculations proving the adequacy of this best management practice for meeting regulatory requirements are provided in Section 5. Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County erection 4. Erosion and Sediment Control Plan. (Provide a reduced, 1 Ix17 copy of the latest Erosion and Sediment Control Plan. Do not reference only.) 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 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 improvements, and/or vegetation. 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 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 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. 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. 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. 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 Operator shall stabilize all exposed earth areas with permanent vegetation as described in the project plans and/or erosion and sediment control narrative.

(reference County Code 17-404 and State Regulation 9VAC25-880-70 part II section A.4) A. Plan showing pollution activities and prevention practices (Provide a reduced I Ix17 copy of a site plan on which all of the following activity locations are clearly marked. Keep this plan up-to-date with ongoing site changes and inspections.) Control of sediments has been described previously. 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. 2. 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 permit shall be obtained by the Operator, prior to discharge. 14ww 3. 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. 4. 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. 5. 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 *AW 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. Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County During the construction phase, the Operator shall implement the following measures where appropriate: NNW 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 Section 4. \.r "`+ 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. 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. 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 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. 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. B.

Pollution Prevention Awareness 1% (Describe training and procedures to provide awareness and compliance for all measures in this document, waste management, wash waters. prevention measures, etc.) If deficiencies in the erosion and sediment control measures are determined, they shall be recorded on the inspection form by the Operator and corrective action shall be initiated b t�perator within the time frame specified below. Between the time this SWPPP is implemented and final site stabilization is achieved, all disturbed areas and pollutant controls must be inspected at one of the two frequencies below: (Operator shall mark chosen inspection frequency) ❑ At least once every four business days or, ❑ At least once every five 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. 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 actions necessary to achieve effective pollutant control ,,.-'he 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. A. 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 must 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 VMW 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 Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County storage areas. N%W 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. 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 b t�perator 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 identify whether the site was in compliance with the SWPPP at the time of inspection and specifically identify all 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 . --tecessary to install additional sediment barriers.) Assessing the need for additional controls and implementing them or adiustina existing controls are key aspects of the effectiveness of this SWPPP until the site achieves final stabilization. Should a control fail, be bypassed or otherwise be ineffective in maintaining sediments onsite and releasing sediment offsite the Operator will 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; • 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. ,%W Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County ,..ciection 7.

If you are covered under the 2012 CGP, this template will enable you to create an inspection report form that is customized to the specific circumstances of your project and that complies with the minimum reporting requirements of Part 4.1.7 of the permit. Note that the use of this form is optional; you may use your own inspection report form provided it includes the minimum information required in Part 4.1.7 of the CGP. If you are covered under a state CGP, this template may be helpful in developing a form that can be used for that permit; however it will need to be modified to meet the specific requirements of that permit. If your permitting authority requires you to use a specific inspection report form, you should not use this form. Notes: While EPA has made every effort to ensure the accuracy of all instructions and guidance contained in the Inspection Report Template, the actual obligations of regulated construction activities are determined by the relevant provisions of the permit, not by the template. In the event of a conflict between the Inspection Report Template and any corresponding provision of the 2012 CGP, you must abide by the requirements in the permit. EPA welcomes comments on the Inspection Report Template at any time and will consider those comments in any future revision of this document. You may contact EPA for CGP-related inquiries at cgp@epa.gov. Overview of Inspection Requirements Construction operators covered under the 2012 CGP are subject to the following requirements in Part 4: Inspection Frequency (see Part 4.1.4) You are required to conduct inspections either: • Once every 7 calendar days; or • Once every 14 calendar days and within 24 hours of a storm event of 0.25 inches or greater. Your inspection frequency is increased if the site discharges to a sensitive water. See Part 4.1.3. Your inspection frequency may be decreased to account for stabilized areas, or for arid, semi -arid, or drought -stricken conditions, or for frozen conditions. See Part 4.1.4. Areas That Need to Be Inspected (see Part 4.1.5) During each inspection, you must inspect the following areas of your site: • Cleared, graded, or excavated areas of the site; • Stormwater controls (e.g., perimeter controls, sediment basins, inlets, exit points etc.) and pollution prevention practices (e.g., pollution prevention practices for vehicle fueling/maintenance and washing, construction product storage, handling, and disposal, etc.) at the site; • Material, waste, or borrow areas covered by the permit, and equipment storage and maintenance areas; • Areas where Stormwater flows within the site; • Stormwater discharge points; and • Areas where stabilization has been implemented. What to Check For During Your Inspection (see Part 4.1.6) During your site inspection, you are required to check: • Whether stormwater controls or pollution prevention practices require maintenance or corrective action, or whether new or modified controls are required; • For the presence of conditions that could lead to spills, leaks, or other pollutant accumulations and discharges; • Whether there are visible signs of erosion and sediment accumulation at points of discharge and to the channels and streambanks that are in the immediate vicinity of the discharge; • If a stormwater discharge is occurring at the time of the inspection, whether there are obvious, visual signs of pollutant discharges; and • If any permit violations have occurred on the site. Inspection Reports (see Part 4.1.7) `„ Within 24 hours of completing each inspection, you are required to complete an inspection report that includes: • Date of inspection; • Names and titles of persons conducting the inspection; • Summary of inspection findings; • Rain gauge or weather station readings if your inspection is triggered by the 0.25 inch storm threshold; and • If you determine that a portion of your site is unsafe to access for the inspection, documentation of what conditions prevented the inspection and where these conditions occurred on the site Instructions for Using This Template This Field Version of the Inspection Report Template is intended to be used in the field and filled out by hand. If you will be filling out the Inspection Report Template electronically (i.e., you will be typing in your findings), please use the Electronic Version of the Inspection Report Template available at www.epa.gov/npdes/stormwater/swppp. The Electronic Version includes text fields with instructions for what to enter. Keep in mind that this document is a template and not an "off -the -shelf" inspection report that is ready to use without some modification. You must first customize this form to include the specifics of your project in order for it to be useable for your inspection reports. Once you have entered all of your site -specific information into these fields, you may print out this form for use in the field to complete inspection reports. The following tips for using this template will help you ensure that the minimum permit requirements are met: • Review the inspection requirements. Before you start developing your inspection report form, read the CGP's Part 4 inspection requirements. This will ensure that you have a working understanding of the permit's underlying inspection requirements. • Complete all required text fields. Fill out all text fields. Only by filling out all fields will the template be compliant with the requirements of the permit. (Note: Where you do not need the number of rows provided in the template form for your inspection, you may leave those rows blank. Or, if you need more space to document your findings, you may add an additional sheet.) • Use your site map to document inspection findings. In several places in the template, you are directed �.. to specify the location of certain features of your site, including where stormwater controls are installed and where you will be stabilizing exposed soil. You are also asked to fill in location information for unsafe conditions and the locations of any discharges occurring during your inspections. Where you are asked for location information, EPA encourages you to reference the point on your SWPPP site map that corresponds to the requested location on the inspection form. Using the site map as a tool in this way will help you conduct efficient inspections, will assist you in evaluating problems found, and will ensure proper documentation. • Sign and certify each inspection report. Each inspection report must be signed and certified by the permittee to be considered complete. Where your inspections are carried out by a contractor or subcontractor, it is recommended that you also have the form signed and certified by the inspector, in addition to the signature and certification required of the permitted operator. The template includes a signature block for both parties. • Include the inspection form with your SWPPP. Once your form is complete, make sure to include a copy of the inspection form in your SWPPP in accordance with Part 7.2.12.4 of the CGP. • Retain copies of all inspection reports with your records. You must also retain in your records copies of all inspection reports in accordance with the requirements in Part 4.1.7.3 of the 2012 CGP. These reports must be retained for at least 3 years from the date your permit coverage expires or is terminated. Section -by -Section Instructions You will find specific instructions corresponding to each section of the report form on the reverse side of each page. These instructions provide you with more details in terms of what EPA expects to be documented in these reports. wid k / § EE & // 6 2 u E kf 2 f u § u ( U 4) / W � e j \ / \ e \ F o % C m N o _ E O p-C 6 j O C a O a)° a) 3 O a) Op a o0 °'�0 0 �-C -0 p 0 .,_ N D a)c a) -0 O •c c a. c o UO Q p0 N O D a) U a) -0 C> v w U C o Q O o) ° a)N "' N O p Q Q U .0 N U N Q O N U M C C c ' a) -O 0 U a) t O Q p Q a) o a)-0a) (7 a) -C = 0 C 3 C ° N C C D Q Q' U N O ''= N c p C w Q a) a O N N° p c o ° _O N-a o a) U O .0 Ca) 0 ,_ O c O OU 0 m Q N o-C U a) O N j -0 N a) Q a) U O p ~ t c Q U o L Q N d>° N> -0 C Sri Q 3 O c p o u ° c m 3- c :_�a)m�a) ) �o a� ��0) w a) ° w 4) �`'' �p OU 0— o2.
