The characteristics of the land cover following tree clearing and mulching activities yield an SCS Curve Number that allows for greater infiltration of excess rainfall. yegetation Pre -construction the site is primarily wooded with a mix of deciduous and non - deciduous trees and shrubs. • Post -construction disturbed open areas will contain a fairly uniform spreading of mulch. Other: The 12 Digit HUC for the property is: 020802040402. Drainage from the site flows into Moores Creek, the Rivanna River — Mechunk Creek, and then ultimately into the James River. • There are a few areas determined to be wetlands located within the project area. These wetland areas will be preserved during the tree cutting and mulching operations. The wetland areas will be included within the "Biscuit Run Park Phase 1 Roadway Improvements Plan" prepared by Kimley-Horn. Stormwater Pollution Prevention Plan (SWPPP) Biscuit Run Park: Phase la Entrance and Parking Erosion & Sediment Control BMPs: Minimize Disturbed Area and Protect Natural Features and Soil. Describe the areas that will be disturbed with each phase of construction and the methods (signs, fences, etc.) that you will use to protect those areas that should not be disturbed. Describe natural features identified earlier and how each will be protected during construction activity. Also describe how topsoil will be preserved. Include these areas and associated BMPs on your site map(s) also. Maximum disturbed area is detailed in the site plan. BMP Description: Tree Protection • Temporary Fencing: Install temporary fencing around tree protection zones to protect remaining trees and vegetation from construction damage. Maintain temporary fence and remove when construction is complete. Fencing should be the last item removed after completion of a project. This fencing will be erected at a radius of 1.50 feet away from the trunk of tree for every inch in stem diameter. Diameter is measured 4.5 feet above the ground. For trees 4 inches or less in diameter the measurement will be at 6 inches above the ground. This radial distance is termed the "critical root zone" and will serve as the Tree Protection Zone (TPZ). Fencing will consist of heavy-duty chain link. Fencing will be rigidly supported and maintained during all construction periods at a minimum height of 6.0 feet above grade. • Signs stating, "No Entry, Tree Protection Area," in both English and Spanish, are to be posted at 30-foot intervals. • Protect tree root systems from damage caused by runoff or spillage of noxious materials while mixing, placing, or storing construction materials. • Protect root systems from ponding, eroding, or excessive wetting caused by watering operations. • Do not store construction materials, debris, or excavated material inside tree protection zones. • Do not permit vehicles or foot traffic within tree protection zones; prevent soil compaction over root systems. • Maintain tree protection zones free of weeds and trash. Installation Schedule: Tree protection fencing should be installed prior to construction activities within the work area. Maintenance and Areas should be checked regularly to identify problems and Inspection: determine if additional controls (e.g., more training, more explicit signage, more obvious barriers) are needed. Inspectors should also look for signs of unintended Stormwater Pollution Prevention Plan (SWPPP) Biscuit Run Park: Phase la Entrance and Parking consequences of construction activities on the natural areas, such as changes in hydrology, flooding, or accidental spills, and take appropriate actions to mitigate the damage. Responsible Staff: Qualified Inspection Personnel TP TREE PROTECTION 2. Control Stormwater Flowing onto and Through the Project: Describe structural practices (i.e., diversions, berms, ditches, storage basins) including design specifications and details used to divert flows from exposed soils, retain or detain flows, or otherwise limit runoff and the discharge of pollutants from exposed areas of the site. Post -construction the mulch covered areas of the site will be used to maintain sheet flow conditions for the site. A shallow stormwater management quantity basin will be utilized within drainage area 4 to meet energy balance requirements. Stormwater Pollution Prevention Plan (SWPPP) Biscuit Run Park: Phase la Entrance and Parking 3. Stabilize Soils: Describe controls (i.e., temporary seeding with native vegetation, hydroseeding, etc.) to stabilize exposed soils where construction activities have temporarily or permanently ceased. Also describe measures to control dust generation. Use of impervious surfaces for stabilization should be avoided whenever possible. BMP Description: Dust Control Dust from the site will be controlled by using a mobile pressure -type distributor truck to apply potable water to disturbed areas. The mobile unit will apply water at a rate of 300 gallons per acre and minimized as necessary to prevent runoff and ponding. Installation Schedule: Dust control will be implemented as needed once site grading has been initiated and during windy conditions (forecasted or actual wind conditions of 20 mph or greater) while site grading is occurring. Spraying of potable water will be performed no more than three times a day during the months of May -September and once per day during the months of October -April or whenever the dryness of soil warrants it. Maintenance and Inspection: At least one mobile unit shall be available at all times to distribute potable water to control dust on the project area. Each mobile unit shall be equipped with a positive shutoff valve to prevent over watering of the disturbed area. Responsible Staff: Responsible Land Disturber see page 2 Stormwater Pollution Prevention Plan (SWPPP) Biscuit Run Park: Phase la Entrance and Parking 4. Protect Slopes: Erosion control blankets and matting, tackifiers, etc. are not being proposed at this time for the scope of this project. BMP Description: Soil Stabilization Blankets & Matting Geotextile erosion control blankets will be used to provide stabilization where necessary. The blanket will cover the entire area of the graded slope. The blanket will be installed by digging a small trench on the upside of the slope, 12 inches wide by 6 inches deep, and stapling the leading edge of the blanket in the trench. The blanket will be rolled down the slope slowly to maintain soil contact and stapled in 12-inch intervals. If the blanket cannot cover the entire slope, the blankets will be overlapped (minimum of 2 inches) and stapled at the overlapped edge. The erosion control blanket will always be installed according to manufacturer's instructions andspecifications. Installation Schedule: The erosion control blankets will be installed once the soil has reached final grade. Maintenance and Inspection: The erosion control blanket will be inspected weekly and immediately after storm events to determine if cracks, tears, or breaches have formed in the fabric; if so, the blanket will be repaired or replaced immediately. Good contact with the soil must be maintained and erosion should not occur under the blanket. Any areas where the blanket is not in close contact with the ground will be repaired or replaced. Responsible Staff: Responsible Land Disturber see page 2 Stormwater Pollution Prevention Plan (SWPPP) Biscuit Run Park: Phase la Entrance and Parking 5. Protect Storm Drain Inlets: Describe controls (i.e., inserts, rock -filled bags, or block and gravel, etc.) including design specifications and details that will be implemented to protect all inlets receiving stormwater from the project during the entire duration of the project. BMP Description: Outlet Protection Structurally lined Outlet protection used for dissipating energy placed at the outlets of pipes or paved channel sections. Outlet protection is used to prevent scour at stormwater outlets and minimize downstream erosion. See ESC narrative (Section 4) for design details and placement. Installation Schedule: The outlet protection will be established when the inlet drainage pipe is installed. This form of protection shall be performed on all stormwater outlets by using ri ra . Maintenance and Inspection: Inspect to ensure against scour. Responsible Staff: Responsible Land Disturber see page 2 Stormwater Pollution Prevention Plan (SWPPP) Biscuit Run Park: Phase la Entrance and Parking 6. Establish perimeter controls and sediment barriers: Describe structural practices (i.e., silt fences or fiber rolls) including design specifications and details to filter and trap sediment before it leaves the construction site. BMP Description: Silt Fence Silt fences will be installed along the disturbed area as shown on the site plan. Silt fences will be installed by excavating a 12-inch-deep trench along the line of proposed installation. Wooden posts supporting the silt fence will be spaced 4 to 6 feet apart and driven securely into the ground: a minimum of 18 to 20 inches deep. The silt fence will be fastened securely to the wooden posts with wire ties spaced every 24 inches at the top, mid -section, and bottom of the wooden post. The bottom edge of the silt fence will be extended across the bottom of the trench and the trench will be backfilled and compacted to prevent stormwater and sediment from discharging underneath the silt fence. Installation Schedule: The silt fence will be installed before construction begins at the site and silt fence locations are illustrated on the plan Section 4). Maintenance and Inspection: Silt fences will be inspected weekly and immediately after storm events to ensure it is intact and that there are no gaps where the fence meets the ground or tears along the length of the fence. If gaps or tears are found during the inspection, the fabric will be repaired or replaced immediately. Accumulated sediment will be removed from the fence base if it reaches one-third the height of the silt fence and hauled off -site for disposal. If accumulated sediment is creating noticeable strain on the fabric and the fence might fail from a sudden storm event, the sediment will be removed more frequently. Before the fence is removed from the project area, the sediment will be removed. The anticipated life span of the silt fence is 6 months and will likely need to be replaced after this period. Responsible Staff: Responsible Land Disturber see page 2 Design Specifications 1. The silt fence will be constructed long enough to extend across the expected flow path. 2. The support posts will be a minimum of 4.5 feet and driven a minimum of 18 to 20 inches in the ground. Posts will be spaced a maximum of 6 feet apart. Fabric will be securely fastened to posts with half -inch staples or 16-gauge wire ties spaced a maximum of 6 inches. 3. A 12-inch trench will be excavated along the uphill side of the silt fence posts. The bottom edge of the fabric will extend across the bottom of the trench. The trench will be backfilled to 4 inches above ground and compacted to bury and secure the bottom of the filter fabric. Stormwater Pollution Prevention Plan (SWPPP) Biscuit Run Park: Phase la Entrance and Parking 7. Retain Sediment On -Site and Control Dewatering Practices: Describe sediment control practices (i.e., sediment trap or sediment basin), including design specifications and details (volume, dimensions, outlet structure) that will be implemented at the construction site to retain sediments on -site. Describe dewatering practices that will be implemented if water must be removed from an area so that construction activity can continue. 8. Establish Stabilized Construction Faits: Describe location(s) of vehicle entrance(s) and exit(s), procedures to remove accumulated sediment off -site (i.e., vehicle tracking), and stabilization practices (i.e., stone pads and/or wash racks) to minimize off -site vehicle tracking of sediments and discharges to stormwater. BMP Description: Temporary Stone Construction Entrance A stone entrance shall be constructed utilizing existing driveways, as identified on the site map, to prevent off -site transport of sediment by construction vehicles. The stone entrance will be at least 70 feet long and a minimum of 10 feet wide. This stone area shall be used for washing sediment from vehicles exiting the site. Where sediment is transported onto a public road surface, the road shall be cleaned thoroughly at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. Installation Schedule: The stabilized exits will be installed before construction begins and shall be adjacent to Scottsville Road (Route 20) as shown on the Erosion & Sediment Control plan ES2.0 . Maintenance and Inspection: The exit will be inspected weekly and after storm events or heavy use. The exit will be maintained in a condition that will prevent tracking or flowing of sediment onto Scottsville Road. All sediment tracked, spilled, dropped, or washed onto Scottsville Road will be swept up immediately and hauled off -site for disposal at the landfill. Broken road pavement as a result of construction activities on roadways immediately adjacent to the project site will be repaired immediately. Alternate Method: The County inspector may, at their discretion, require the use of a paved construction entrance as an alternate to the stone construction entrance. For details see E&SC plan details in the Appendix. Responsible Staff: Responsible Land Disturber see page 2 9.

There are no existing BMPs located within the project area. Watershed for the site is the Moores Creek Watershed. The HUC for the project is: 020802040402. Stormwater Management - Post Construction Post -construction stormwater will flow through mulched areas to maintain sheet flow. A shallow stormwater quantity basin will be constructed within drainage area 4 to meet energy balance requirements. Stormwater Management - Summary: Stormwater Quantity: Post -construction stormwater from the park will convey via sheet flow to one of six points of interest identified for evaluating stormwater quantity impacts. One shallow stormwater quantity basin will be installed to meet energy balance regulations under 9VAC25-870-66B.3.a. for channel protection. State Regulation 9VAC25-870-66.C.3.D. shall be met by conveying stormwater via sheet flow through the use of mulching. Stormwater Quality: The County will meet stormwater quality regulations under 9VAC25-870-65 by purchasing offsite nutrient credits to offset the impact of site improvements. 100 FN Stormwater Management Narrative: Water Quantity: Pre -Construction Site Conditions: There are six drainage divides located within the project area. Stormwater quantity was evaluated at each of these points of interest for pre -construction and post -construction conditions. Point of Interest 1: Drainage area 1 drains via overland flow to the point of interest. In the pre -construction condition the drainage area is wooded with a mix of deciduous and non -deciduous trees. Point of Interest 2: Drainage area 2 drains via overland flow to the point of interest prior to entering an exisitng 24" CMP. This pipe conveys under the existing roadway. In the pre -construction condition the drainage area is wooded with a mix of deciduous and non -deciduous trees. A portion of the existing roadway for Avon Street Ext. and Scottsville Road (Route 20) converge at point of interest 2. Point of Interest 3: Drainage area 3 drains via overland flow to the point of interest. This point of interest is located prior to entering an existing 21" DI pipe. This pipe conveys under the existing roadway. In the pre -construction condition the drainage area is wooded with a mix of deciduous and non -deciduous trees. A portion of the existing roadway for Scottsville Road (Route 20) conveys through point of interest 3. Point of Interest 4: Drainage area 4 drains via overland flow to the point of interest prior to entering an exisitng 18" CMP. This pipe conveys under the existing roadway. In the pre -construction condition the drainage area is wooded with a mix of deciduous and non -deciduous trees. A portion of the existing roadway for Scottsville Road (Route 20) conveys through point of interest 4. Point of Interest 5: Drainage area 5 drains via overland flow to the point of interest prior to entering an unnamed tributary. In the pre -construction condition the drainage area is wooded with a mix of deciduous and non -deciduous trees. Point of Interest 6: Drainage area 6 drains via overland flow to the point of interest prior to entering an unnamed tributary. In the pre -construction condition the drainage area is wooded with a mix of deciduous and non -deciduous trees. A portion of the existing roadway for Scottsville Road (Route 20) conveys through point of interest 6. Post -Construction Site Conditions: Post -construction improvements include tree clearing and mulching 9.8 acres of the site. The post -construction conditions of the site were evaluated at each point of interest to ensure State Regulations are being met. The following improvements were made to the existing drainage pattern in order to meet energy balance requirements: Point of Interest 1: The post -construction condition contains 0.73 acres of mulched area. Post -construction drainage for drainage area 1 flows through the point of interest before travelling overland and ultimately entering an existing culvert. The overall drainage pattern will remain relatively unchanged from the pre -construction to the post -construction condition. Point of Interest 2: The post -construction condition contains 1.48 acres of mulched area. Post -construction drainage for drainage area 2 flows through the point of interest before entering the existing 24" CMP. The overall drainage pattern will remain relatively unchanged from the pre -construction to the post -construction condition. Point of Interest 3: The post -construction condition contains 4.63 acres of mulched area. Post -construction drainage for drainage area 3 flows through the point of interest before entering the existing 21" DI pipe. The overall drainage pattern will remain relatively unchanged from the pre -construction to the post -construction condition. Point of Interest 4: The post -construction condition contains 0.89 acres of mulched area. Post -construction drainage for drainage area 4 flows through the point of interest before entering the existing 18" CMP. A shallow stormwater quantity control device will be installed to reduce stormwater flow within the existing swale. This device is located just upstream of the right-of-way line within the existing swale for drainage area 4. See C-601 for location information. See C-612 for device details. Point of Interest 5: The post -construction condition contains 0.82 acres of mulched area. Post -construction drainage for drainage area 5 flows through the point of interest before entering the existing tributary to Biscuit Run. The overall drainage pattern will remain relatively unchanged from the pre -construction to the post -construction condition. Point of Interest 6: The post -construction condition contains 1.28 acres of mulched area. Post -construction drainage for drainage area 6 flows through the point of interest before entering the existing tributary to Biscuit Run. The overall drainage pattern will remain relatively unchanged from the pre -construction to the post -construction condition. Method of Analysis: The six points of interest for our analysis were chosen as the point where all drainage from each drainage divide converge. These points allow for the quantification of stormwater including all new improvements. A shallow stormwater quantity control basin is being proposed on -site to meet State regulations and energy balance. Adjacent property information, field -run survey, and County GIS documents were utilized to develop the limits of each drainage divide. Rain data was obtained from NOAA National Weather Service Data. Soil information was obtained from the United States Department of Agriculture Natural Resources Conservation Service for soil surveys. A curve number (CN) of 98 was assumed for all impervious surfaces, a CN of 48 was assumed for the proposed cleared and mulched cover area, and a CN of 55 was assumed for all wooded areas. These assumptions were based on soil information obtained from the U.S. Department of Agriculture (USDA) web soil survey, the USDA National Engineering Handbook and with the recommendations found in the Virginia Stormwater Management Handbook Volume II, Chapter 4, Table 4-6b for agricultural lands. The curve number for the proposed new cleared land area with intermixed mulched cover was interpolated and based upon similar land cover examples for brush -weed -grass mixture in hydrologic group type B soils. The existing wooded area of the park was primarily pasture land as recently as 15 years ago. Due to the abundance of pioneer tree species that populates the park today, there is currently a good amount of young undergrowth shrub and meadow grasses interspersed amongst the wooded areas. The existing trees to be cleared will be transformed into mulch containing a mixture of cedars, pines, and deciduous trees. Proposed erosion and sediment control measures for the tree clearing would combine the mulched areas with new temporary grass seeding. The plan specifies a post -construction tree clearing area with undergrowth shrub, new and existing grasses and the addition of a fairly uniform spreading of wood mulch. Pre -construction and post -construction flows were modelled using HydroCAD software to demonstrate that this project meets energy balance and State regulations. The modelling software projected flow rates were then analyzed to confirm that energy balance requirements will be achieved with the proposed site improvements. Summary: Channel Protection: Pre -construction and post -construction peak flows and runoff volumes were calculated at each point of interest. See the summary for these calculations on plan sheet C-602. Drainage conveyed at each point of interest is shown to meet energy balance in the post -construction condition of the site. The energy balance at the point of interest for the 1-YR, 24-hr storm is being met with the proposed site improvements. This satifies VSMP regulations under Part II B, Water Quantity (9VAC25-870-66.B.3.a.). Flood Protection: The post -construction condition of the site includes 9.9 acres of cleared land. The cleared area will contain a fairly uniform spreading of mulch. This mulched area will act as an erosion control and stormwater measure. The mulch will continue to sheet flow the stormwater to the point of interest. Sheet flow satisfies VSMP regulations under Part II B, Water Quantity (9VAC25-870-66.C.3.D). I_�10III NV GI VI Water Quality: Pre -Construction Site Conditions: There are no existing stormwater quality measures located on -site. Post -Construction Site Conditions: The Owner (Albemarle County, Lesee) is eligible to purchase offsite nutrient credits under Albemarle County Code, Chapter 17, Sec. 17-502.A.2. due to the total post -construction pollution control (measured in phosphorus) requirement totalling less than 10 lb/yr. The County intends to purchase offsite stormwater nutrient credits to meet State Regulated stormwater quality requirements. Method of Analysis: Impervious and pervious surfaces for pre -construction and post -construction site conditions were quanitfied and entered into the DEQ VRRM spreadsheet. This allowed us to ensure that State required stormwater quality benchmarks are being met with the proposed site improvements. Summary: The County will purchase nutrient credits to meet Water Quality (9VAC25-870-65). The DEQ VRRM spreadsheet summary can be found on sheet C-630 of the plan set. The proposed improvements require 0.46 Ib/yr of total phosporus nutrient loads.

This general permit also authorizes stormwater discharges from support activities (e.g., concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated material disposal areas, borrow areas) located on -site or off -site provided that: a. The support activity is directly related to the construction activity that is required to have general permit coverage for discharges of stormwater from construction activities; b. The support activity is not a commercial operation, nor does it serve multiple unrelated construction activities by different operators; c. The support activity does not operate beyond the completion of the last construction activity it supports; d. The support activity is identified in the registration statement at the time of general permit coverage; e. Appropriate control measures are identified in a stormwater pollution prevention plan and implemented to address the discharges from the support activity areas; and f. All applicable state, federal, and local approvals are obtained for the support activity. B. Limitations on coverage. 1. Post -construction discharges. This general permit does not authorize stormwater discharges that originate from the site after construction activities have been completed and the site, including any support activity sites covered under the general permit registration, has undergone final stabilization. Post -construction industrial stormwater discharges may need to be covered by a separate VPDES permit. Discharges mixed with nonstormwater. This general permit does not authorize discharges that are mixed with sources of nonstormwater, other than those discharges that are identified in Part I E (Authorized nonstormwater discharges) and are in compliance with this general permit. Discharges covered by another state permit. This general permit does not authorize discharges of stormwater from construction activities that have been covered under an individual permit or required to obtain coverage under an alternative general permit.

Where an inspection report does not identify any incidents of noncompliance, the report shall contain a certification that the construction activity is in compliance with the SWPPP and this general permit. The report shall be signed in accordance with Part III K of this general permit. H. Corrective actions. The operator shall implement the corrective actions identified as a result of an inspection as soon as practicable but no later than seven days after discovery or a longer period as approved by the VSMP authority. If approval of a corrective action by a regulatory authority (e.g., VSMP authority, VESCP authority, or the department) is necessary, additional control measures shall be implemented to minimize pollutants in stormwater discharges until such approvals can be obtained. The operator may be required to remove accumulated sediment deposits located outside of the construction activity covered by this general permit as soon as practicable in order to minimize environmental impacts. The operator shall notify the VSMP authority and the department as well as obtain all applicable federal, state, and local authorizations, approvals, and permits prior to the removal of sediments accumulated in surface waters including wetlands. Page 18 of 26 PART III CONDITIONS APPLICABLE TO ALL VPDES PERMITS NOTE: Discharge monitoring is not required for this general permit. If the operator chooses to monitor stormwater discharges or control measures, the operator shall comply with the requirements of subsections A, B, and C, as appropriate. A. Monitoring. 1. Samples and measurements taken for the purpose of monitoring shall be representative of the monitoring activity. Monitoring shall be conducted according to procedures approved under 40 CFR Part 136 or alternative methods approved by the U.S. Environmental Protection Agency, unless other procedures have been specified in this general permit. Analyses performed according to test procedures approved under 40 CFR Part 136 shall be performed by an environmental laboratory certified under regulations adopted by the Department of General Services (1 VAC30-45 or 1 VAC30-46). 3.

This period of retention shall be extended automatically during the course of any unresolved litigation regarding the regulated activity or regarding control standards applicable to the operator, or as requested by the board. C. Reporting monitoring results. Page 19 of 26 1. The operator shall update the SWPPP to include the results of the monitoring as may be performed in accordance with this general permit, unless another reporting schedule is specified elsewhere in this general permit. 2. Monitoring results shall be reported on a discharge monitoring report (DMR); on forms provided, approved or specified by the department; or in any format provided that the date, location, parameter, method, and result of the monitoring activity are included. If the operator monitors any pollutant specifically addressed by this general permit more frequently than required by this general permit using test procedures approved under 40 CFR Part 136 or using other test procedures approved by the U.S. Environmental Protection Agency or using procedures specified in this general permit, the results of this monitoring shall be included in the calculation and reporting of the data submitted in the DMR or reporting form specified by the department. 4. Calculations for all limitations which require averaging of measurements shall utilize an arithmetic mean unless otherwise specified in this general permit. D. Duty to provide information. The operator shall furnish, within a reasonable time, any information which the board may request to determine whether cause exists for terminating this general permit coverage or to determine compliance with this general permit. The board, department, EPA, or VSMP authority may require the operator to furnish, upon request, such plans, specifications, and other pertinent information as may be necessary to determine the effect of the wastes from his discharge on the quality of surface waters, or such other information as may be necessary to accomplish the purposes of the CWA and the Virginia Stormwater Management Act. The operator shall also furnish to the board, department, EPA, or VSMP authority, upon request, copies of records required to be kept by this general permit. E. Compliance schedule reports. Reports of compliance or noncompliance with, or any progress reports on, interim and final requirements contained in any compliance schedule of this general permit shall be submitted no later than 14 days following each schedule date. F. Unauthorized stormwater discharges. Pursuant to § 62.1-44.5 of the Code of Virginia, except in compliance with a state permit issued by the department, it shall be unlawful to cause a stormwater discharge from a construction activity. G. Reports of unauthorized discharges. Any operator who discharges or causes or allows a discharge of sewage, industrial waste, other wastes or any noxious or deleterious substance or a hazardous substance or oil in an amount equal to or in excess of a reportable quantity established under either 40 CFR Part 110, 40 CFR Part 117, 40 CFR Part 302, or § 62.1-44.34:19 of the Code of Virginia that occurs during a 24-hour period into or upon surface waters or who discharges or causes or allows a discharge that may reasonably be expected to enter surface waters, shall notify the Department of Environmental Quality of the discharge immediately upon discovery of the discharge, but in no case later than within 24 hours after said discovery. A written report of the unauthorized discharge shall be submitted to the department and the VSMP authority within five days of discovery of the discharge. The written report shall contain: 1. A description of the nature and location of the discharge; 2. The cause of the discharge; Page 20 of 26 3. The date on which the discharge occurred; 4. The length of time that the discharge continued; 5. The volume of the discharge; 6. If the discharge is continuing, how long it is expected to continue; 7. If the discharge is continuing, what the expected total volume of the discharge will be; and Any steps planned or taken to reduce, eliminate and prevent a recurrence of the present discharge or any future discharges not authorized by this general permit. Discharges reportable to the department and the VSMP authority under the immediate reporting requirements of other regulations are exempted from this requirement. H. Reports of unusual or extraordinary discharges. If any unusual or extraordinary discharge including a "bypass" or "upset," as defined in this general permit, should occur from a facility and the discharge enters or could be expected to enter surface waters, the operator shall promptly notify, in no case later than within 24 hours, the department and the VSMP authority by telephone after the discovery of the discharge. This notification shall provide all available details of the incident, including any adverse effects on aquatic life and the known number of fish killed. The operator shall reduce the report to writing and shall submit it to the department and the VSMP authority within five days of discovery of the discharge in accordance with Part III 12. Unusual and extraordinary discharges include any discharge resulting from: 1. Unusual spillage of materials resulting directly or indirectly from processing operations; 2. Breakdown of processing or accessory equipment; 3. Failure or taking out of service of some or all of the facilities; and 4. Flooding or other acts of nature. I. Reports of noncompliance. The operator shall report any noncompliance which may adversely affect surface waters or may endanger public health. An oral report to the department and the VSMP authority shall be provided within 24 hours from the time the operator becomes aware of the circumstances. The following shall be included as information that shall be reported within 24 hours under this subdivision: a. Any unanticipated bypass; and b. Any upset that causes a discharge to surface waters. 2. A written report shall be submitted within five days and shall contain: a. A description of the noncompliance and its cause; Page 21 of 26 b. The period of noncompliance, including exact dates and times, and if the noncompliance has not been corrected, the anticipated time it is expected to continue; and c. Steps taken or planned to reduce, eliminate, and prevent reoccurrence of the noncompliance. The department may waive the written report on a case -by -case basis for reports of noncompliance under Part III I if the oral report has been received within 24 hours and no adverse impact on surface waters has been reported. 3. The operator shall report all instances of noncompliance not reported under Part III 1 1 or 2 in writing as part of the SWPPP. The reports shall contain the information listed in Part 111 1 2. NOTE: The reports required in Part III G, H and I shall be made to the department and the VSMP authority. Reports may be made by telephone, email, or by fax. For reports outside normal working hours, leaving a recorded message shall fulfill the immediate reporting requirement. For emergencies, the Virginia Department of Emergency Management maintains a 24-hour telephone service at 1-800-468-8892. 4. Where the operator becomes aware of a failure to submit any relevant facts, or submittal of incorrect information in any report, including a registration statement, to the department or the VSMP authority, the operator shall promptly submit such facts or correct information. J. Notice of planned changes. 1. The operator shall give notice to the department and the VSMP authority as soon as possible of any planned physical alterations or additions to the permitted facility or activity. Notice is required only when: a. The operator plans an alteration or addition to any building, structure, facility, or installation that may meet one of the criteria for determining whether a facility is a new source in 9VAC25-870-420; b. The operator plans an alteration or addition that would significantly change the nature or increase the quantity of pollutants discharged. This notification applies to pollutants that are not subject to effluent limitations in this general permit; or 2. The operator shall give advance notice to the department and VSMP authority of any planned changes in the permitted facility or activity, which may result in noncompliance with state permit requirements. K. Signatory requirements. 1. Registration statement. All registration statements shall be signed as follows: a. For a corporation: by a responsible corporate officer. For the purpose of this chapter, a responsible corporate officer means: (i) a president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy -making or decision -making functions for the corporation; or (ii) the manager of one or more manufacturing, production, or operating facilities, provided the Page 22 of 26 manager is authorized to make management decisions that govern the operation of the regulated facility including having the explicit or implicit duty of making major capital investment recommendations, and initiating and directing other comprehensive measures to assure long-term compliance with environmental laws and regulations; the manager can ensure that the necessary systems are established or actions taken to gather complete and accurate information for state permit application requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures; b. For a partnership or sole proprietorship: by a general partner or the proprietor, respectively; or c. For a municipality, state, federal, or other public agency: by either a principal executive officer or ranking elected official. For purposes of this chapter, a principal executive officer of a public agency includes (i) the chief executive officer of the agency or (ii) a senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency. 2. Reports and other information. All reports required by this general permit, including SWPPPs, and other information requested by the board or the department shall be signed by a person described in Part III K 1 or by a duly authorized representative of that person. A person is a duly authorized representative only if: a. The authorization is made in writing by a person described in Part III K 1; b. The authorization specifies either an individual or a position having responsibility for the overall operation of the regulated facility or activity such as the position of plant manager, operator of a well or a well field, superintendent, position of equivalent responsibility, or an individual or position having overall responsibility for environmental matters for the operator. (A duly authorized representative may thus be either a named individual or any individual occupying a named position); and c. The signed and dated written authorization is included in the SWPPP. A copy shall be provided to the department and VSMP authority, if requested. 3. Changes to authorization. If an authorization under Part III K 2 is no longer accurate because a different individual or position has responsibility for the overall operation of the construction activity, a new authorization satisfying the requirements of Part III K 2 shall be submitted to the VSMP authority as the administering entity for the board prior to or together with any reports or information to be signed by an authorized representative. 4. Certification. Any person signing a document under Part III K 1 or 2 shall make the following certification: "I certify under penalty of law that I have read and understand this document and that this document and all attachments were prepared in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant Page 23 of 26 penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations." L. Duty to comply. The operator shall comply with all conditions of this general permit. Any state permit noncompliance constitutes a violation of the Virginia Stormwater Management Act and the Clean Water Act, except that noncompliance with certain provisions of this general permit may constitute a violation of the Virginia Stormwater Management Act but not the Clean Water Act. Permit noncompliance is grounds for enforcement action; for state permit coverage, termination, revocation and reissuance, or modification; or denial of a state permit renewal application. The operator shall comply with effluent standards or prohibitions established under § 307(a) of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish these standards or prohibitions or standards for sewage sludge use or disposal, even if this general permit has not yet been modified to incorporate the requirement. M. Duty to reapply. If the operator wishes to continue an activity regulated by this general permit after the expiration date of this general permit, the operator shall submit a new registration statement at least 60 days before the expiration date of the existing general permit, unless permission for a later date has been granted by the board. The board shall not grant permission for registration statements to be submitted later than the expiration date of the existing general permit. N. Effect of a state permit. This general permit does not convey any property rights in either real or personal property or any exclusive privileges, nor does it authorize any injury to private property or invasion of personal rights, or any infringement of federal, state or local law or regulations. O. State law. Nothing in this general permit shall be construed to preclude the institution of any legal action under, or relieve the operator from any responsibilities, liabilities, or penalties established pursuant to any other state law or regulation or under authority preserved by § 510 of the Clean Water Act. Except as provided in general permit conditions on "bypassing" (Part III U) and "upset' (Part III V), nothing in this general permit shall be construed to relieve the operator from civil and criminal penalties for noncompliance. P. Oil and hazardous substance liability. Nothing in this general permit shall be construed to preclude the institution of any legal action or relieve the operator from any responsibilities, liabilities, or penalties to which the operator is or may be subject under §§ 62.1-44.34:14 through 62.1-44.34:23 of the State Water Control Law or § 311 of the Clean Water Act. Q. Proper operation and maintenance. The operator shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances), which are installed or used by the operator to achieve compliance with the conditions of this general permit. Proper operation and maintenance also includes effective plant performance, adequate funding, adequate staffing, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems, which are installed by the operator only when the operation is necessary to achieve compliance with the conditions of this general permit. R. Disposal of solids or sludges. Solids, sludges or other pollutants removed in the course of treatment or management of pollutants shall be disposed of in a manner so as to prevent any pollutant from such materials from entering surface waters and in compliance with all applicable state and federal laws and regulations. Page 24 of 26 S. Duty to mitigate. The operator shall take all steps to minimize or prevent any discharge in violation of this general permit that has a reasonable likelihood of adversely affecting human health or the environment. T. Need to halt or reduce activity not a defense. It shall not be a defense for an operator in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this general permit. U. Bypass. 1. 'Bypass," as defined in 9VAC25-870-10, means the intentional diversion of waste streams from any portion of a treatment facility. The operator may allow any bypass to occur that does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to ensure efficient operation. These bypasses are not subject to the provisions of Part III U 2 and 3. 2. Notice. a. Anticipated bypass. If the operator knows in advance of the need for a bypass, the operator shall submit prior notice to the department, if possible at least 10 days before the date of the bypass. b. Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as required in Part III I. 3. Prohibition of bypass. a. Except as provided in Part III U 1, bypass is prohibited, and the board or department may take enforcement action against an operator for bypass unless: (1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage. Severe property damage means substantial physical damage to property, damage to the treatment facilities that causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production; (2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventive maintenance; and (3) The operator submitted notices as required under Part III U 2. b. The department may approve an anticipated bypass, after considering its adverse effects, if the department determines that it will meet the three conditions listed in Part III U 3 a. Page 25 of 26 V. Upset. 1. An "upset," as defined in 9VAC25-870-10, means an exceptional incident in which there is unintentional and temporary noncompliance with technology -based state permit effluent limitations because of factors beyond the reasonable control of the operator. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. 2. An upset constitutes an affirmative defense to an action brought for noncompliance with technology -based state permit effluent limitations if the requirements of Part III V 4 are met. A determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is not a final administrative action subject to judicial review. 3. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation. 4. An operator who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs or other relevant evidence that: a. An upset occurred and that the operator can identify the cause of the upset; b. The permitted facility was at the time being properly operated; c. The operator submitted notice of the upset as required in Part III I; and d. The operator complied with any remedial measures required under Part III S. 5. In any enforcement proceeding, the operator seeking to establish the occurrence of an upset has the burden of proof. W. Inspection and entry. The operator shall allow the department as the board's designee, the VSMP authority, EPA, or an authorized representative of either entity (including an authorized contractor), upon presentation of credentials and other documents as may be required by law to: 1. Enter upon the operator's premises where a regulated facility or activity is located or conducted, or where records shall be kept under the conditions of this general permit; 2. Have access to and copy, at reasonable times, any records that shall be kept under the conditions of this general permit; 3. Inspect and photograph at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this general permit; and 4. Sample or monitor at reasonable times, for the purposes of ensuring state permit compliance or as otherwise authorized by the Clean Water Act or the Virginia Stormwater Management Act, any substances or parameters at any location. Page 26 of 26 For purposes of this section, the time for inspection shall be deemed reasonable during regular business hours, and whenever the facility is discharging. Nothing contained herein shall make an inspection unreasonable during an emergency. X. State permit actions. State permit coverage may be modified, revoked and reissued, or terminated for cause. The filing of a request by the operator for a state permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any state permit condition. Y. Transfer of state permit coverage. 1. State permits are not transferable to any person except after notice to the department. Except as provided in Part III Y 2, a state permit may be transferred by the operator to a new operator only if the state permit has been modified or revoked and reissued, or a minor modification made, to identify the new operator and incorporate such other requirements as may be necessary under the Virginia Stormwater Management Act and the Clean Water Act. As an alternative to transfers under Part III Y 1, this state permit may be automatically transferred to a new operator if: a. The current operator notifies the department at least 30 days in advance of the proposed transfer of the title to the facility or property; b. The notice includes a written agreement between the existing and new operators containing a specific date for transfer of state permit responsibility, coverage, and liability between them; and c. The department does not notify the existing operator and the proposed new operator of its intent to modify or revoke and reissue the state permit. If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in Part III Y 2 b. 3. For ongoing construction activity involving a change of operator, the new operator shall accept and maintain the existing SWPPP, or prepare and implement a new SWPPP prior to taking over operations at the site. Z. Severability. The provisions of this general permit are severable, and if any provision of this general permit or the application of any provision of this state permit to any circumstance, is held invalid, the application of such provision to other circumstances and the remainder of this general permit shall not be affected thereby. Stormwater Pollution Prevention Plan (SWPPP) Biscuit Run Park: Phase la Entrance and Parking SECTION 12: INSPECTIONS and MAINTENANCE 12.1 Inspections Project Information: 1. Inspection Personnel. The Contractor will conduct inspections and the Contractor will bear primary responsibility for inspections of all Erosion and Sediment Control devices and pollution prevention measures to ensure continuing effectiveness. The inspector must be considered Qualified Personnel. Qualified personnel means a licensed professional engineer, responsible land disturber (RLD), or other knowledgeable person who holds a certificate of competence from the board in the area of project inspection, is enrolled in the board's training program for project inspection or combined administrator, and successfully completes such program within one year of enrollment. 2. Inspection Schedule and Procedures: i. Inspections will be conducted at least once every 14 calendar days and within 48 hours following any runoff producing storm event. Where areas have been temporarily stabilized or runoff is unlikely due to winter conditions (e.g., the site is covered with snow or ice, or frozen ground exists) such inspections will be conducted at least once every month. ii. Inspections must include all areas of the site disturbed by construction activity, off -site areas (covered by the permit), and areas used for storage of materials that are exposed to precipitation. Inspectors must look for evidence of, or the potential for, pollutants entering a stormwater conveyance system. Control measures identified in the SWPPP shall be inspected for proper installation, maintenance, and operation. Discharge locations, where accessible, shall be inspected to ascertain whether control measures are effective in minimizing impacts to receiving waters. Where discharge locations are inaccessible, nearby downstream locations shall be inspected to the extent that such inspections are practicable. Locations where vehicles enter or exit the site shall be inspected for evidence of off -site sediment tracking. iii. Major observations should include: the location(s) of discharges of sediment or other pollutants from the site; amount of rainfall at the construction site since the previous inspection; weather information and a description of any discharges occurring at the time of inspection; location(s) of control measures that need to be maintained; location(s) of control measures that failed to operate as designed or proved inadequate for a particular location; and location(s) where additional control measures are needed that did not exist at the time of inspection. iv. All vegetative and structural erosion and sediment control practices shall be constructed and maintained according to minimum standards and specifications of the Virginia Erosion and Sediment Control Handbook. Stormwater Pollution Prevention Plan (SWPPP) Biscuit Run Park: Phase la Entrance and Parking V. Contractor shall prepare a report summarizing the scope of the inspection, names and qualifications of personnel making the inspection, the dates of the inspection, major observations relating to the implementation of the SWPPP, and actions taken in accordance with stonnwater regulations.
