New forms were developed during the Plan development. The Plan has been developed to address the requirements of NPDES General Permit No. NCG080000. The current General Permit was re -issued by NCDWQ effective November 1, 2007. For purposes of this Plan, this facility is in the first year of the General Permit coverage term; thus new procedures for documenting Permit compliance are effective in Year 1. Table 1 identifies those permit compliance tasks which require documentation. Master originals of the forms and checklists identified in Table 1 are located in Appendix A. Implementation of the SWPPP should commence no later than 12 months from the effective date of the initial certificate of coverage (COC) of the Stormwater Permit. Target dates indicated are based on the Permit requirements. Table 1 is formatted to provide the user with a permanent record of Permit compliance. The user will fill in the status bullet and enter the completion date onto Table 1 when the tasks are implemented. All copies or originals of all documentation regarding the Permit and this Plan including completed forms, checklists, and sampling records are then inserted into Appendix F. Tables similar to Table 1 are provided for subsequent years in Appendix A. Use the designated table for each year of Permit coverage. Potential or existing pollutant or spill source item identified during site investigations conducted for the preparation of this Plan are identified in this document and on the facility area maps. 1 Make working copies of the Appendix A master forms and checklists for field use and documentation.

Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page viii 1. STORMWATER POLLUTION PREVENTION PLAN This Stormwater Pollution Prevention Plan (SWPPP) has been prepared to comply with the United States Environmental Protection Agency (EPA) National Pollutant Discharge Elimination System (NPDES) program under the amended 1977 Federal Water Pollution Control Act. The SWPPP has been developed using information from Stormwater Management for Industrial Activities: Developing Pollution Prevention Plans and Best Management Practice (USEPA, 1992). This SWPPP replaces all previous SWPPPs written for this Permittee. A SWPPP consists of steps and activities designed to identify potential sources of stormwater pollution or contamination, and establishes Best Management Practices (BMPs) that will prevent or reduce pollutants in stormwater runoff. This SWPPP has been prepared in accordance with standard engineering practices. The North Carolina Department of Environment and Natural Resources (NCDENR), Division of Water Quality (DWQ), has adopted final stormwater permitting rules for industrial discharges in North Carolina. North Carolina is a delegated NPDES state with general and individual permitting authority. EPA regulations 40 CFR 122 require most industrial facilities to apply for a NPDES permit for stormwater discharges. This facility is covered by NPDES General Permit No. NCG080000, which expires October 31, 20122. The Fleet Maintenance Garage has been issued Certificate -of -Coverage (COC) Number NCGO80801. The personnel at this facility are required to: • Learn and implement stormwater pollution prevention procedures and requirements; • Establish spill containment procedures, drainage control, and security measures; • Follow written standard operation procedures for hazardous material handling and storage; • Perform routine site inspections; and • Maintain records to document successful completion of SWPPP requirements. Technical and economic feasibility issues are a baseline consideration in choosing BMPs that will be performed during the first year of permit compliance. Expensive or unproved technologies are dismissed early in the selection process. The result is a list of practical BMPs (see Table 5) that the facility will implement. Additional BMPs, including structural controls, will be evaluated during the first annual Plan review. BMP evaluation will consider the potential for sources to contribute pollutants and a review of previous qualitative monitoring reports. The following appendices are included as part of this SWPPP: Appendix A contains the required documentation (administrative forms and inspection checklists) to be used at this facility. Appendix B contains SWPPP guidance information relevant to the SWPPP tasks and duties of the SWPPT. Plan amendments are filed in Appendix C. Appendix D contains SWPPP-related acronyms and definitions. Appendix E contains the COC and Permit issued to this facility located in Winston- Salem. Completed checklists and forms will be inserted into Appendix F. 2 A Notice -of -Intent renewal is submitted to NCDWQ 180 days before the Permit expires. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 1 1.1 General Location Map The Fleet Services Department is located south of Business I-40 and immediately west of US 52 approximately one mile southeast of the City's central business district. The site has a total area of about eight acres of which about 100% is used for industrial activity. The surrounding area consists of industrial and institutional development. There are no residential properties within 500 feet of this facility. Map 1 shows the location of the facility: Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 2 Insert Aerial Photograph here. Figure 1— Aerial View Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 4 1.2 Site Drainage The facility is located in the central Piedmont physiographic region. Locally, the soils are fill material over an abandoned landfill. The local soils have been disturbed due to construction of the facility and are probably more compacted near the surface than the natural soils in the vicinity. Maintaining or regenerating an adequate plant cover can minimize wind erosion and off -site sedimentation. The general topography of the site is flat with slopes to the south and southwest. The high ground lies to the northeast of the yard. The site is paved where industrial activities occur, except for gravel at the heavy equipment parking area. It is likely that spills of hazardous materials would quickly enter nearby inlets and could potentially enter nearby waters of the State via the facility's storm drainage system, or as surface flow, depending on the location of the spill. According to FEMA Flood Insurance Rate Map Panel No. 37067CO278H (1998) none of this Facility's buildings are within a mapped 100-year flood zone. However, Bath Branch, adjacent to the Yard on the west, has a mapped 100-year flood zone to a point upstream of Stadium Drive. The facility is located within the Yadkin River Basin, a tributary to the Pee Dee River. Runoff from this facility drains southwestward into Bath Branch upstream of its confluence with Salem Creek. Five industrial stormwater discharge outfalls (SDO) are located at the facility; refer to Table 2. A visual observation of the topography and land use surrounding the garage indicates that there are nearby industrial facilities. There is no runoff from other industrial properties onto this Permittee's facility, nor does off -site industrial runoff enter any of this Permittee's stormwater drainage outfalls. There is a culvert that passes under the west side of the site that carries street runoff originating north of Stadium Drive. This facility's SDO-01 discharges into this culvert. Offsite stormwater drainage systems are not mapped as part of this SWPPP. Leaks from off -site underground fuel tanks or spills beyond natural or manmade ridgelines could enter this Permittee's property due to groundwater flow. A groundwater study was not conducted as part of this Plan development and such flow patterns are not known. The industrial drainage outfalls are identified in Table 2. The approximate location of these outfalls (defined here as point source discharges of stormwater to "waters of the State") are shown in the table.

Visual and analytical monitoring will be conducted at all outfalls as described in Appendix B. Other discretionary points within the facility that may be useful to isolate potential pollutant sources can be identified and observed by the Permittee. 1.3 Discharges to 303d-Listed Streams The closest receiving stream, Salem Creek, is a 303d-listed stream from Salem Lake downstream to its confluence with Muddy Creek as of the effective date of this Plan. Salem Creek is a 303d- listed stream for Ecological/Biological Integrity Benthos. The field study portion of TMDL development for Bacteria in Salem Creek commenced October 28, 2002. A TMDL for Fecal coliform has been established for Salem Creek as follows: Fecal coliform shall not exceed a geometric mean of 200/100 ml (membrane filter count) based upon at least five consecutive samples examined during any 30 day period, nor exceed 400/100 ml in more than 20 percent of the samples examined during such period. Bath Branch is not a 303d-listed stream as of the effective date of this SWPPP. This facility does not have a reasonable potential for violating the Salem Creek water quality standards due to its stormwater discharges. Wet weather sampling will be performed in order to evaluate pollutant loadings into the adjacent creeks. Based upon the pollutant loads, additional structural and non-structural BMPs may be necessary to prevent further degradation to the receiving surface waters. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 6 1.4 FACILITY INDUSTRIAL ACTIVITY This garage has the following baseline industrial activities: Hazardous Materials Handling Loading docks and tanker receiving areas are considered industrial activity areas when hazardous materials are received and shipped and there is a reasonable potential for a spill or leak of said materials entering the stormwater drainage system or waters of the State. Hazardous Materials Storage Storage areas for new and waste materials such as antifreeze, gasoline, diesel fuel, and oils are included when the storage areas are either directly exposed to rainfall or when spills or leaks from these areas have the potential to enter the storm drainage system. Materials used and stored at this facility include toxics, oxidizers, and flammables. Equipment Maintenance & Repair Equipment maintenance practices are addressed when there is a potential for a release of oil or other chemical during the maintenance or repair activity. Equipment that could cause a release includes fuel pumps and pressurized supply lines. Vehicle Washing Vehicle washing activities, including the storage and use of detergents, are addressed when there is a potential for wash or rinse water flows to enter the storm drainage system. Non -Hazardous Materials Processes Areas where abandoned equipment, scrap debris, and trash are accumulated and handled are subject to stormwater controls where there is a reasonable potential for the items to enter the storm drainage system via surface runoff. Hazardous Waste Generation and Accumulation Central and satellite accumulation points are addressed where there is a potential for the storage areas or spills to be exposed to precipitation or stormwater runoff. This facility does not generate regulated hazardous wastes as of the effective date of this Plan. However, there is a possibility that certain spill clean ups may result in the short-term accumulation of a hazardous waste. 1.4.1 Activity Descriptions The site -specific industrial activities performed at the facility include maintenance and repair of City -owned vehicles (e.g., automobiles, garbage trucks), equipment repair and maintenance, vehicle refueling, and vehicle washing. The layout of the facility is shown on Maps 2 through 7. The site maps identify building locations, hazmat storage, the stormwater drainage system, potential pollution sources, and stormwater discharge outfalls. Table 3 below provides a written description of the various site -specific industrial activity areas, potential pollutant sources, and implemented BMPs: Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 7 TABLE 3 - INDUSTRIAL ACTIVITY AREAS AREA ACTIVITIES POLLUTANTS IMPLEMENTED BMPs A Vehicle Maintenance & Repair Oil, Grease, Fuel Vehicles are serviced inside a Antifreeze garage.

Significant spills are defined as those spills that have at least one of the following characteristics: • The spilled material enters either adjacent creek, • The spilled material flows off the property, • The spilled material causes injury to personnel • The spilled material contaminates the soil, adjacent wetlands, or waters of the State, or • The spilled quantity exceeds a regulatory reporting limit. A summary of significant spill incidents are noted in Table 5 below. The detailed spill report (use Form 8 or similar) is filed in Appendix F. TABLE 5 — SIGNIFICANT SPILLS DATE SPILLED MATERIAL QUANTITY CORRECTIVE ACTION Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 10 1.6 Outfall Certification The consultants conducted an investigation at this facility on May, 2008. During this investigation, no illicit connections were identified. Several improper discharges were identified and include: • There are oil drips on the pavement where vehicles are parked. • There are fuel stains on the pavement in the vicinity of the fuel island. • There are oil drips on the gravel where equipment is parked. • Wash/ rinse water escapes from wash bays and flows into CB#4.1. As a point of reference, wash waters containing detergents, other cleaning agents, or degreasers cannot be directly discharged to the stormwater drainage system under NPDES General Permit No. NCG080000. Refer to the section on Equipment Cleaning Areas for additional information. Illicit connections and improper discharges, where identified now or in the future, must be plugged and abandoned, authorized under a separate NPDES permit, or re-routed to a municipal sanitary sewer system. The following certification will be signed each year for the term of the General Permit. Blank master forms for subsequent years are found in Appendix A. Special Notes: June 25 2008 @ 0902 hrs — The City's Stormwater Division staff conducted dye -testing of the trench drains in the heavy equipment garage area. Dye was observed in the adjacent downstream sanitary sewer manhole, thus confirming the trench drain system discharges to the City's sanitary sewer system. July 2 2008 — The City's Streets Department staff unearthed and raised the manhole covers at MH#1.1 and MH#1.4 to the current grade. These manholes are now accessible to the Fleet Services staff for monitoring purposes. 3 Floor drains that connect to a process water or sanitary sewer system are not considered illicit under NPDES General Permit NCG080000. However, other permits address discharges to the sanitary sewer system and expressly prohibit slug discharges. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 11 CERTIFICATION OF NON-STORMWATER DISCHARGES I certify, under penalty of law, that the stormwater outfalls covered by this Permit have been tested or evaluated for the presence of non-stormwater discharges under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of those persons, to the best of my knowledge and belief, no non -permitted discharges of non-stormwater enter the stormwater outfalls covered by this Permit because of activities occurring at this facility [as specified in Part II, Section A, Paragraph 1(e) of the Permit]. Print Name and Official Title: Signature: Date Signed: Representing: Fleet Services Department 650 Rams Drive Winston-Salem, North Carolina 27101 Methods of Evaluation Used: Q Review of building and site plans. Q Visual inspection of storm drainage system components (e.g., catch basins, manholes). Q Observation of outfalls on a dry day that was preceded by at least 72 hours of dry weather. Q Interview with facility personnel. Q Flow tests using water, tracers, dyes, or smoke. The Permittee is aware of the upset or bypass notification procedures as specified in the facility s NPDES Permit and will act accordingly (See Part III, Sections C and E of the Permit). Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 12 2. STORMWATER MANAGEMENT PLAN 2.1 Feasibility Study The BMPs selected for this operator to implement have been determined to be reasonable, effective, and feasible. It is not feasible to cover the equipment parking area nor the vehicle parking lot. All ASTs, except AST-8 and AST-9, are located inside the garage and are secondarily contained. The Permittee has determined that it will be feasible to provide secondary containment for all future ASTs that may be placed into service. For ASTs that will be located inside a building, the operator will either provide a secondary containment structure for that AST, or raise the doorway thresholds a sufficient amount to contain 110% of the spillable volume. AST-8 and AST-9 are constructed of HDPE and are not subject to corrosion or traffic damage. The Permittee will work with the vendor to obtain double -walled tanks or spill pallets within 24 months of the effective date of this Plan. 2.2 Risk Assessment One operation that has a moderate risk of contributing to a large spill (more than 100 gallons) that may enter the stormwater drainage system is the delivery of fuel to the site. The vendor's tanker is not secondarily contained when it is parked next to the USTs during the filling process. A second operation that has a moderate risk of contributing to a large spill (more than 100 gallons) is the transfer of used oil from the ASTs into the vendor's tanker. The vendor's tanker is not secondarily contained when it is parked next to the ASTs during the transfer process. Another operation that has a moderate risk of contributing to a medium spill (more than 55 gallons) that may enter the stormwater drainage system is the transfer of the oils and other fluids within the garage. This operation involves moving full 55-gallon drums by hand or truck. This operation occurs indoors and outdoors. Refer to the SPCC Plan for a detailed description of oil handling activities. The daily routine handling of motor oils, lubricants, and hydraulic fluids presents a moderate risk of small (<55 gallons) and incidental spills (<25 gallons). Regular spill prevention awareness training will help minimize accidental spills and leaks. Other pollutant risks are minor as all operations take place inside the building. Most containers used as dispensers are positioned away from exterior doors. Some POL containers and dispensers are placed on spill pallets that provide secondary containment. The building construction limits exposure of leaks from interior tanks, but close -proximity containment will minimize the spread of leaks across the interior floors. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 13 Most hazardous material storage areas are located away from exterior doors and are in secure containers. Locating spill kits close to potential spill sources will reduce the risk of spills contaminating the environment and provide readily available defensive controls in the event of a spill. Materials (e.g. trash, debris, scrap metal) subject to long-term exposure to precipitation represent a high risk of stormwater pollution and should be protected from precipitation. Exposed materials can leach metals, chemicals, and other pollutants into stormwater due to contact with acidic rainfall, abrasive winds, and natural decomposition. 2.3 Secondary Containment Requirements Secondary containment for bulk storage of liquid materials, storage of Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals, or storage of hazardous substances to prevent leaks and spills from contaminating stormwater runoff will be provided for all such containers within 12 months of the effective date of this Plan. If the secondary containment devices are connected directly to stormwater conveyance systems, the connection will be controlled by manually activated valves or other similar devices [which will be secured with a locking mechanism] and any stormwater that accumulates in the containment area will be at a visually observed for color, foam, outfall staining, visible sheens and dry weather flow, prior to release of the accumulated stormwater. 2.4 Policy for Pumping Out Secondary Containment Structures These steps will be followed: 1. Any rainwater or other material accumulated or spilled inside an exposed secondary containment structure will be visually observed and recorded using BMP Checklist #5. 2. Measure the pH of the accumulated material. If pH is in the range 6.0 — 9.0 and no other visual observations indicate a chemical or oil spill, the accumulated material can be released onto the ground. If pH is not in the range of 6.0 — 9.0, then the SWPPT Leader will be notified prior to the material's removal. 3. If other visual observations indicate a spill or leak into the containment structure, the SWPPT Leader will be notified immediately. The SWPPT Leader will coordinate the proper and legal handling and transport of the contaminated material. 4. Material accumulated inside a non -exposed secondary containment structure will be considered a waste product and will be properly disposed. No accumulated rainwater that shows evidence of contamination will be released or discharged from a secondary containment structure onto the ground or into the street, ditch, stormwater conveyance system. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 14 2.5 Best Management Practices Summary Table 6 lists the BMPs that were in place on the effective date of this Plan and the new BMPs scheduled to be implemented by this Plan. Solid bullets indicate existing or completed BMPs and hollow bullets indicate proposed BMPs. The Target Date indicates the latest date at which the BMP should be implemented. The hollow status bullets will be filled in and the SWPPT Leader will enter implementation dates in the table when the tasks are implemented. Complete implementation of proposed BMPs, including secondary containment as specified in the Permit, should be accomplished within 12 months of the effective date of the initial COC of the Permit. BMPs may be added, deleted, or modified during the annual reviews as the Permittee determines effectiveness and feasibility. Changes must be documented through narrative amendments. BMP amendments will be inserted into Appendix F. The following BMPs are in place and operating properly, or are required for this facility: 2.5.1 Handling and Disposal of Hazardous Substances This facility stores and uses batteries, automotive chemicals, antifreeze, fuels, and oils. These hazardous substances are stored at the facility in containers ranging is size from 16-oz aerosol cans to 55-gallon drums to several bulk aboveground storage tanks. This facility has designated areas for storage of hazardous and flammable materials. Receiving of bulk chemicals and POL is typically limited to the hours between 7:00 am and 4:00 pm Monday through Friday. However, bulk fuel can be delivered at any time. All pails and drums containing hazardous substances should be placed on spill pallets or within a secondary containment area. Flammables cabinets should be provided in the garage for storage of aerosols, paints, lubricants, and other hazardous substances. Spill kits should also be positioned near hazmat storage areas. Incompatible materials such as flammables and oxiders will be stored at least 50 feet apart. The best solution for hazardous substance storage is to place containers inside a pre -fabricated metal hazmat storage building with integral secondary containment. These pre-fab buildings also provide fire and explosion protection. This option is expensive and requires available space to erect the building. Another suitable method is to construct a concrete curb around the area where drums and tanks will be located. Secondary containment that is not exposed to precipitation should have a volume equal to 110% of the largest container within the containment. If the containment structure is exposed to precipitation, provide containment for 100% of the largest tank and then add 5.77 Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 15 inches to the height of the containment wall or curb. A ramp can be provided to allow access for drum handling equipment. Drums that are used as dispensing units should be set on spill -containment pallets. Dispenser drums exposed to precipitation will be set within a clam -shell or other type covered spill - containment pallet. 2.5.2 Regulated Hazardous Wastes Wastes that are deemed hazardous should be stored in areas protected from precipitation. Spill kits pre -positioned near hazardous waste accumulation areas will aid in quick response to leaks and spills. Hazardous wastes should not be stored in close proximity to new hazardous materials. Central and satellite waste accumulation points have certain standards — refer to 40 CFR 262 for further information. 2.5.3 Aboveground Storage Tanks Aboveground storage tanks (ASTs) exposed to precipitation must be provided with secondary containment that equals 100% of the largest AST volume plus 5.77 inches of freeboards. By providing protection from rainfall (e.g., a shed roof over the AST and containment), the potential for releasing pollutants, as well as the regulatory burden, is reduced. If rainfall is prevented from accumulating within the secondary containment structure, then inspection and documentation of releases can be avoided. Interior ASTs will be provided with secondary containment that equals 110% of the largest AST within the contained area. Interior ASTs can be provided with individual curbs or dikes, or the room can provide secondary containment with raised thresholds and eliminating holes and drains through the walls and floor. Individual secondary containment is preferred as it prevents the spread of the spilled material and possible recovery and re -use. ASTs will also be marked with the contents, capacity, a unique identification number, and the 4- color diamond placard. These markings will help emergency response personnel to identify hazards, and help prevent accidents due to overfilling, or mixing incompatible chemicals. ASTs and secondary containment structures are subject to semi-annual inspections as indicated in the BMP Status table. a This is the approximate depth of rainfall from the 25-year, 24-hour storm event in Winston-Salem, North Carolina (TR-55 - Urban Hydrology for Small Watersheds, USDA Soil Conservation Service, 1986). 5 The net volume of secondary containment must consider the volume displaced by other tanks and appurtenances within the containment area. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 16 2.5.4 Inlet Inserts All catch basins within the facility boundary should be provided with inlet inserts designed to trap oil & grease and/ or sediment, depending on the pollutant of concern. These inserts will be inspected monthly for the first year, and then at an appropriate interval thereafter but not less than once every six months. The inserts will be cleaned once every three months and replaced as necessary to achieve maximum pollutant trapping. 2.5.5 Vegetated Buffers Vegetated buffers provide for infiltration of stormwater and a slowing down of runoff velocity. Vegetation can also uptake some pollutants common to stonmwater runoff. Areas on the site that are currently vegetated will be maintained with a good growth of grass, shrubs, and trees. Other areas on the site that are not needed for parking or vehicle access can be converted to vegetated buffers. Inspect twice yearly to ensure adequacy to slow runoff and prevent erosion. Vegetated buffers should be maintained with grass trimmed to a height of four (4) to six (6) inches tall. The planting of small shrubs will improve runoff detention and pollutant uptake. Other vegetated buffers such as around building perimeters and along public right-of-ways should be maintained with grass and other small plantings as appropriate. Allow runoff to flow through grass buffers. Denser vegetation such as shrubs and trees provide better stormwater management. Where possible, runoff can be diverted into a simple infiltration/ detention device known as a level spreader. This device resembles a willow u- or v-shaped grass -lined ditch with almost no slope. Runoff enters the level spreader and flows toward each end, slowly infiltrating, or running over the down -gradient edge as sheet flow. 2.5.6 Inlet Markings Inlets that connect to the storm drainage system can marked with a phrase such as "Drains to Yadkin River — Do Not Dump." This will help educate employees and vendors on pollution awareness and prevention and minimize the risk that improper disposals will occur. 2.5.7 Riprap Apron Velocity Dissipator An appropriately designed riprap apron consisting of Class B rock will be installed the end of any outlet pipe where erosion is evident. All riprap will be laid on a geotextile fabric liner.

SPILL PREVENTION AND RESPONSE The Permit requires that the Permittee develop a spill prevention and response component within the SWPPP document. This section meets the requirements. 3.1 Materials of Concern The spill sources with a reasonable risk for contaminating stormwater include the storage and handling of fuel, oil, lubricants, and water treatment chemicals. Accidents and careless handling during these activities can cause spilled liquids to enter the storm drainage system. The following spillable and potentially hazardous or polluting materials are used, collected, and stored in significant quantities at this facility: TABLE 8 — HAZARDOUS SUBSTANCES Item Typical Quantity On -Site Method of Storage New Antifreeze 100 gals 1-gallon jugs New Motor Oil 4200 AST Gear Oil 80W90 3600 AST Transmission Fluid 2000 AST Used Antifreeze 500 AST/ Tote Used Oil 500 AST Detergent 500 AST Windshield Wiper Fluid Gasoline 20,000 UST Diesel Fuel 20,000 UST Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 21 Spill Prevention During transfer of hazardous materials to and from the Permittee's facility, the driver of the delivery vehicle will be responsible for preventing spills. The driver will ensure that all hoses are secure and that absorbent materials (pads and socks) are available before commencing the fluid transfer. Absorbent pads and booms are to be provided by the Permittee and located near the hazmat delivery/ connection points. During all bulk POL operations, the tanker driver will remain with the vehicle at all times. In addition to the driver remaining at the tanker vehicle during the transfer, a designated garage employee will observe the bulk fuel delivery area for signs of leaks and spillage as soon after the transfer is completed as practical. Preferably, this observation should occur as the driver checks out and before the tanker leaves the site. Employee awareness is the key to an effective spill prevention and response program. Spill prevention training will be a component of the general employee training program. New personnel will be taught spill prevention practices. The spill response team will gain a sufficient understanding of the objectives of the spill prevention program. Spill prevention training will highlight previous spill events, equipment failures, remedies taken, and newly developed prevention measures. The SWPPT Leader will evaluate the spill prevention program once each year. Spill prevention items that are addressed within this SWPPP and may need annual review and revision include: • Review and update materials inventory list (emphasis on hazardous substances) • Identify potential spill sources • Establish incident reporting procedures • Develop inspection procedures • Review previous incidents • Establish a training program • Review new construction and proposed operational changes Spill Response In case of large volume or significant spills, this facility can request aid from the local Fire Department6 (dial 911) or a private vendor to provide emergency spill response. Minor spills can be absorbed using absorbent wipes, pads or booms. All liquid materials are stored and used inside the building or are otherwise not normally exposed to the storm drainage system. Small spills can be controlled by sweeping or mopping the material into approved containers for proper disposal. Proper disposal includes removing absorbent materials from the floor on a timely basis. The facility will follow spill response procedures outlined below. This facility uses many different hazardous substances, some in large quantities. Similar precautions regarding other materials are 6 The facility may request an annual inspection from the local Fire Marshall's office. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 22 necessary. Spills that occur outside on paved vehicle parking lots may discharge to the storm drain system. There is always concern about preventing soil contamination and a concern of preventing any spills from reaching the storm drain system. Reasonable measures necessary to prevent contamination of soil or waters of the State will be carried out. There are four basic steps that are to be taken to control pollution that can result from a spill: 1. Stop the spill at the source. 2. Contain the spill using appropriate defensive actions. 3. Collect the spilled material if trained and directed to do so. 4. Dispose of the spilled material and subsequent contaminated material properly and legally. If containment methods are required for which you are not trained, or personal protective equipment is not available, immediately evacuate the contaminated area and prevent unauthorized personnel from entering. Steps 3 and 4 should only be undertaken by personnel that are properly trained in spill response and cleanup. 3.2 Initial Response Actions Many of the chemicals used at this facility are combustible. Remove or turn off sources of ignition in vicinity of spills. Do not attempt actions for which you are not properly trained or equipped. Personnel safety and protection of life and limb take precedence over environmental protection. The normal course of action in the event of a hazardous materials spill is to: a. Initiate evacuation, if necessary. b. Notify your immediate supervisor. If supervisor is not available, notify the SWPPT Leader. The third in line for notification is any on -call supervisor. The SWPPT Leader is responsible for making external notifications based on the type and nature of the spill or disaster. The SWPPT Leader will ensure that appropriate facility personnel are notified and will direct control and cleanup efforts. Leaks and minor spillage will also be reported to insure appropriate action is taken to correct deficiencies or malfunctions that caused the discharge. c. Stop spill flow when possible without undue risk of personal injury. The attempt to stop the source of a spill should be made only by those personnel sufficiently familiar with the spilled substance and equipment as to provide an effective response without undue risk of personal injury. Most employees are instructed to go no further than Step 2. Never attempt actions for which you are not trained. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 23 d. Contain the spill using spill response equipment or whatever means is readily available. e. Make spill scene OFF LIMITS to unauthorized personnel. f. Restrict all sources of ignition when flammable/ combustible substances are involved. g. Report to the incident commander upon his/ her arrival to the scene. The sequence of initial response action may be altered depending upon individual spill characteristics (e.g., type of spill, quantity of spill, and/or safety hazards involved). Initial information is critical. Pre-printed Form #8, which asks pertinent questions, is included in Appendix A. Answers to some of these questions will not be immediately known, but it is important to quickly gather as much information as possible without putting personnel in danger. Identification number, shipping manifests, and placard information are essential for the identification of the spilled or leaked material. First responders can use DOT'S Emergency Response Guidebook to help identify hazardous substances, and for guidance on initial precautionary and containment steps. 3.3 Additional Emergency Actions a. In case of fire/ explosion, activate the fire alarm system, telephone 911, and evacuate the area. b. Prohibit smoking or open flames within the spill hazard zone. c. Equipment with magneto -sparked engines or equipment that produce sparks or static electricity located within the spill hazard zone will disconnected during spill response activities. d. Do not use any material that would cause oil to sink or disperse. e. Place chemical -soaked sorbents and soil into plastic bags, then into metal, leak -tight drums. Label and dispose the drums properly. For releases originating outside of the facility, the site maps will be consulted to determine the potential flow direction of the spill. Water bodies downstream from where spills could be discharged may need to be monitored. In the event additional personnel and/or services are required, the local fire department or outside contractors may be employed. For spills that result in a slug discharge to the City's sanitary sewer system, the Facility SWPPT Leader will notify the City of Winston-Salem's WWTPB at 336-765-0130, xl 102. 8 The City of Winston-Salem operates the Fleet Maintenance Garage to which this facility discharges sanitary sewerage. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 24 Contracts or agreements with contractors, transporters, or similar personnel for movement of such commodities as paints, lubricants, and fuel, in or out of the facility, will stipulate that the contractor, transporter, or similar person will be responsible for cleanup of spills on the facility caused by their negligence. The agreement will also stipulate once these contracted personnel leave the physical confines of this site, this Permittee's responsibility for their actions terminates. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 25 3.4 Notification of Releases Facility personnel will be notified of a spill that could pose an immediate threat to their health through the telephone system, PA system or word of mouth where practical. The SWPPT Leader will be notified by telephone or voice of all spills of oil or hazardous substances immediately. The SWPPT Leader will be responsible for notifying off -site agencies of reportable spills. Only the SWPPT Leader or his designee will contact off -site agencies.

Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCGO80801 Page 26 3.5 Spill Response Tools Industrial facilities using hazardous substances should obtain spill response tools appropriate for the facility. The SWPPT Leader will assess the hazardous substances and potential spill conditions at this facility and acquire necessary items. Table C.3 provides a guideline for tools that may be needed for a safe response to a spill of stain, mineral spirits, or other hazardous substances at the facility. Not all items shown may be required at this facility. The SWPPT Leader will indicate on the table available tools and location at least once per year.

Inspections will uncover conditions such as cracks or slow leaks that could cause breakdowns or failures that result in discharges of chemicals (e.g., antifreeze, lubricants) or particulate matter (e.g., solids, paint chips, dirt) to the storm drainage system. The program will reduce breakdowns and failures by making proper adjustments, repair, or replacement of equipment or parts. Standard operating procedures include two specific preventative maintenance periods: • Run-time preventative maintenance occurs daily during each shift as normal operation of the equipment and machinery. • Scheduled preventative maintenance on a regular basis that will involve inspections, cleaning, and minor repairs to equipment. The following items, if present at the facility, are subject to periodic inspections as they have a direct risk to stormwater. The Permit requires written documentation of scheduled inspections that are performed in compliance with this Permit. Inspections that occur more frequently than shown below are not required to be documented under the terms of this Permit. • Oil/ Water Separator: Items such as the piping, electrical components, filters, and gauges will be checked for wear. Routine maintenance will adjust and replace items as needed. Oil/ Water Separators will be inspected once every six months and pumped out as needed. • Oil pumps: These devices are subject to frequent inspection and maintenance that includes lubrication, balancing, repacking bearings, and tightening of support bolts and pipe connections. The pump manufacturers' recommendations will be followed. Seals, couplings, and valves will be inspected and replaced as needed. Oil pumps will be inspected once every six months. • Compressors: Compressors are often sources of an oily mist that is deposited around the compressor. Compressors also leak lubricants. Compressors will be inspected once every six months and maintained to prevent oily discharges. • Mobile Equipment: These machines (e.g., forklifts, hoists) will be inspected for leaking hydraulic fluids, fuel lines, and lubricating oils. Mobile equipment will be inspected once every six months. • Secondary containment structures: These structures will be equipped with a locking valve controlling discharge. The valves will be locked in the closed position. Discharges will be made in accordance with the Permit and other applicable regulations. The inspector will observe the structural integrity, valve and lock operation, and look for signs that the enclosed tank(s) may be leaking. Exposed secondary containment structures will be inspected once every six months. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 28 • Pipes and supply lines: Pressurized hazardous substance supply pipes will be inspected once every six months. Special attention will be made to supports, connectors, couplers, and valves. • Other: Equipment used for recycling or filtering various compounds will be inspected and maintained as directed by the original manufacturer. Other equipment that presents a reasonable risk for stormwater pollution will be inspected once every six months. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 29 5. GOOD HOUSEKEEPING PROGRAM Good housekeeping is the preservation of a clean and orderly work environment that contributes to overall facility pollution control efforts. The execution of this program may also include some materials management practices as they relate to storage of drums and bench stock in the work areas. Adherence to the following practices will minimize the potential for stormwater pollution: • Maintain dry and clean floors. Interior floors will be swept as needed, with residue placed in designated waste disposal containers. Loading docks and building perimeters will be kept clear of scrap material and debris. • Trash and litter will be picked up on a regular basis and disposed properly. • Separate metal holding cans will be provided for oily rags and solvent wipes for fire prevention. • Drip pans will be emptied as needed with collected drippings disposed properly. • The exterior grounds will be policed regularly. Litter and other trash will be disposed properly. Scrap parts and empty drums will be removed from the facility promptly. • All equipment will be visually inspected for leaks and other conditions that could lead to a discharge of a pollutant to waters of the State. • Hazardous substances will be stored in approved containers. The containers will be stored in an area not exposed to stormwater. The containers will be located away from direct vehicular traffic and preferably within secondary containment. • Containers of liquids will be placed on spill containment pallets or racks to prevent corrosion and contain leaks. Pallets and non -cleaned drums will not be stored exposed to precipitation. • Containers of chemicals and other compounds or mixtures will be labeled with name of substance, stock number, expiration date, health hazards, safe handling requirements, and first aid information. For each chemical substance used, a Material Safety Data Sheet (MSDS) will be provided in areas accessible to personnel. • Good housekeeping procedures will be included in the employee training program. Regularly scheduled meetings will be held to discuss good housekeeping and pollution prevention concepts. • Contractors performing work on -site will be instructed to practice good housekeeping in the immediate vicinity of their work and material storage areas. • Remove trash, debris & dirt from wash bays so waste water drains to the sanitary sewer. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 30 5.1 Daily Observations A weekly walk-through of the entire plant is conducted by Fleet Services Supervisor or designated staff. A written record is not required nor kept for these observations. Particular attention is made in regards to leaks, spills, and operating equipment. Problems are be reported and corrected as soon as practical. The following list serves as a guide to critical items: • Tanks and Drums - observe for leaks and corrosion. • Check for fuel and lubricant leaks from equipment. • Check secondary containment structures. Drains, where installed, should be closed and locked. • Liquid -product Delivery Trucks (e.g., tankers) - observe for leaks and malfunctioning valves. • Look for unusual stains on walls, floors, and grounds. • Look for deterioration of equipment foundations and anchorages. • Check for and remove litter and debris from storm drain inlets. • Are any unusual odors detected? • Is equipment operating properly? Is excessive noise, vibration, or exhaust present? • Are the work areas kept in a clean and orderly manner? Practice good housekeeping. • Observe pipelines. Look for deteriorating gaskets, supports, and loose valve stems. • Make sure all valves are in proper position. Check that valves are not leaking. • Look for leaking containers. Replace as necessary. • Check condition of all spill response kits and quantity of absorbent materials. • Clear access to all safety equipment such as eyewashes, fire extinguishers, and spill response kits. • Clear access to emergency exit doors. Emergency exit doors must be kept unlocked during all work hours. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 31 5.2 Vehicle and Equipment Cleaning Areas General Permit NCGO80000 specifically addresses the issue of wash waters. This facility will establish measures to prevent the point source discharge of wash and rinse waters to the storm drainage system or directly to waters of the State. These measures are included here to provide guidance. The Permittee must ensure that all wash waters discharge in accordance with the Permit". If a sanitary sewer system is not available to the facility and cleaning operations take place outdoors, the cleaning operations will take place on level grassed or graveled areas to prevent point source discharges of the wash water into storm drains or surface waters. Where cleaning operations cannot be performed as described above and when operations are performed in the vicinity of a storm drainage collection system, the drain is to be covered with a portable drain cover during cleaning activities. Any excess ponded water will be removed and properly handled by pump to a sanitary sewer system prior to removing the drain cover. Detergents will be biodegradable and the pH adjusted to be in the range of 6 to 9 standard units. The following methods are recommended to prevent or minimize contamination of the stormwater runoff from areas used for vehicle and/or equipment cleaning operations: • Perform all cleaning operations so that wash waters discharge to the sanitary sewer; • Provide cover for outdoor cleaning operations; • Collect wash water runoff from outdoor cleaning areas and provide treatment or recycling; or • Other equivalent measures. An adequate wash area can be provided by designating a gravel pad away from the stormwater discharge outfalls (SDOs) and constructing a low gravel berm around the pad that would contain the wash water and allow infiltration into the ground. Important Note: The point source discharge of vehicle or equipment wash or rinse water, including tank and drum cleaning operations, to a stormwater drainage system is not authorized by NPDES General Permit No. NCGO80000 and must be covered under a separate NPDES general or individual permit or discharged to a sanitary sewer in accordance with applicable local industrial pretreatment requirements. Wash waters may be discharged to a municipal sanitary sewer system as long as slug discharges are prevented in accordance with local ordinances. " NCGO80000 does not allow the discharge of wash waters into the storm drainage system by exclusion from its definition of allowable discharges. Rinse water is defined as a process wastewater, which also cannot be discharged through any of the outfalls. Wash and rinse waters are prohibited discharges under other local and federal regulations.

EMPLOYEE TRAINING Training schedules will be developed and training provided at a minimum on an annual basis on proper spill response and cleanup procedures and preventative maintenance activities for all personnel involved in any of the facility's operations that have the potential to contaminate stormwater runoff. All employees will be trained according to the guidelines indicated in Appendix B, Personnel Training. The SWPPT Leader will coordinate with an instructor, set the training workshop dates, and designate attendees. The target dates for the annual Permit and SWPPP compliance workshop are shown on the compliance tasks schedules. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 33 7. RESPONSIBLE PARTY The responsibilities of the Stormwater Pollution Prevention Team (SWPPT) are to: • Schedule the actions to be performed as directed in the SWPPP; • Monitor stormwater discharges as specified in the Permit; • Conduct semi-annual site inspections; • Implement best management practices; • Perform record keeping and documentation as required by the SWPPP; • Perform the annual updating and certifications as required by the SWPPP; • Evaluate the adequacy of the SWPPP; and • Modify the SWPPP as necessary to achieve reasonable pollutant reductions at the facility. The General Services Supervisor will designate the SWPPT Leader and Members. The organizational arrangement of the SWPPT is presented schematically in Section 7.1. A chart showing actual names, areas of responsibility, and telephone numbers is provided in Appendix F. The SWPPT will meet at least annually to evaluate the effectiveness of the BMPs and determine if additional BMPs need to be incorporated at the facility. A series of BMP checklists are included in Appendix A to assist the team in the evaluation of their assigned areas. The SWPPT is required to make revisions to the Plan where changes to the facility affect the potential risks to stormwater quality. These revisions can be simple and brief narratives inserted as amendments to the original Plan (Use Record of Amendments form provided in Appendix A). The Plan may need to be updated or re -written when the Permit is renewed. 7.1 SWPPT Organization Chart General Services Supervisor Consultants SWPPT Leader City of Winston - Jewell Engineering Salem Consultants, PC Stormwater Division Stormwater Services Groun.

PLAN AMENDMENTS The Permittee will amend the Plan whenever there is a change in design, construction, operation, or maintenance which has a significant effect on the potential for the discharge of pollutants to surface waters. The Stormwater Pollution Prevention Plan will be reviewed and updated on an annual basis. The Director may notify the Permittee when the Plan does not meet one or more of the minimum requirements of the permit. Within 30 days of such notice, the Permittee will submit a time schedule to the Director for modifying the Plan to meet minimum requirements. The Permittee will provide certification in writing (in accordance with Part III, Standard Conditions, Section B, Paragraph 5) to the Director that the changes have been made. Records of amendments will be made using a copy of Form 5. Completed forms and amendment summaries are inserted into Appendix C. Fleet Maintenance Garage Stormwater Pollution Prevention Plan NPDES Permit No. NCG080801 Page 35 9. FACILITY INSPECTION PROGRAM Permittees are required to inspect the facility and all stormwater systems on a semiannual basis, once during the January through June period and once during the July through December period, with at least 60 days separating the inspection dates unless inspections are performed more frequently. These semi-annual inspections will be performed on a dry day that has been preceded by at least 72 hours of dry weather. Refer to the compliance task schedules for the inspection target dates. The inspection and any subsequent maintenance activities performed will be documented, recording date and time of inspection, individual(s) making the inspection and a narrative description of the facility's stormwater control systems, plant equipment and systems. BMP Checklists #1 through #6 are provided to document these semi-annual site inspections. Records of these inspections will be inserted into the SWPPP at Appendix F. 10. STORMWATER MONITORING Analytical monitoring of stormwater discharges will be performed as specified in the Permit at Part II Section B. Samples will be collected during a representative rainfall event once during the January through June period and once during the July through December period, with at least 60 days separating the monitoring dates unless monitoring is performed more frequently. Stormwater discharge qualitative monitoring as required in Part II Section D of the permit will be performed in addition to the facility site inspections. Wet weather discharge monitoring (i.e., visual observations) will occur once during the January through June period and once during the July through December period, with at least 60 days separating the monitoring dates unless monitoring is performed more frequently. Qualitative Monitoring must be performed during the same representative storm event when the discharge samples are collected. Qualitative Monitoring will be performed at all industrial outfalls. A copy of BMP Checklist #6 will be used to document these wet weather visual observations. Refer to the compliance task schedules for the outfall monitoring target dates.
