Street: 841 Sungro Drive City: Elizabeth City State: NC Zip Code: 27909 Latitude/Longitude (Use one of three possible formats, and specify method) Latitude: 36`17'18.74" N Longitude: 76'16'32.67" W Stormwater runoff from the subject site or facility is received by: Knobbs Creek (Pasquotank River Basin) 1.2 Point of Responsibility Burl Domecq, Plant Superintendent is responsible for maintaining and implementing this SWPPP. The responsible person listed above will identify the facility stormwater pollution prevention team, and assign responsibilities, as necessary, to accomplish the requirements of this plan. The Pollution Prevention Team is identified below. Staff Names General Responsibilities Steven Byrum Conduct routine inspections of plant equipment and storage Plant Foreman facilities with regard to stormwater pollution. Each member of the stormwater pollution prevention team must have ready access to either an electronic or paper copy of applicable portions of the SWPPP. Stormwater Pollution Prevention Plan (SWPPP) Barnhill Contracting, Co. — 841 Sungro Drive 1.3 General Location Map Appendix A provides a general location map (U.S. Geological Survey (USGS) 7.5 minute quadrangle map) showing the location of the facility and all receiving waters for stormwater discharges. 1.4 Site Map Appendix B provides a site map of the facility boundary and size of the property in acres and locations of the activities listed in Table 1 below. SECTION 2: POTENTIAL POLLUTANT SOURCES 2.1 Associated Pollutants The site, being an asphalt plant, stores materials needed to produce hot -mix asphalt concrete. Table 1 below lists the associated pollutants on-site. These activities are shown on the site map in Appendix B. Table 1 Associated Pollutants Quantity Location on Site Map AC -20 Liquid Asphalt 30,000 gal. above ground tank S1 Heating Oil (Plant Process) 20,000 gal. above ground tank S2 Asphalt Shingle Stockpiles Bulk SH Sand/Aggregate Stockpiles Bulk SA Recycled Asphalt Milling (RAP) Bulk RA The facility utilizes twenty (20) dump trucks for product hauling, which are maintained on-site. 2.2 Spills and Discharges Appendix C provides a list of spills or leaks of pollutants that have occurred at the facility during the three (3) previous years and the corrective actions taken to mitigate spill impacts. 2.3 Non-Stormwater Discharge Documentation Appendix D provides the visual assessment form used during the initial evaluation of non- stormwater discharges at the facility. Information gathered included: drainage point ID, drainage point type, and dry -weather flow. Outfalls identified with non-stormwater flow were evaluated further. Stormwater Pollution Prevention Plan (SWPPP) Barnhill Contracting, Co. — 841 Sungro Drive SECTION 3: STORMWATER CONTROL MEASURES 3.1 Structural Controls The structural controls shown on the Site Map (Appendix B) are described below. These controls are used to minimize the exposure of the activities identified in Section 2.1. • (S1) AC -20 Liquid Asphalt: Routine Inspections; Drip Pans to catch minor oil leaks • (S2) Heating Oil: Routine Inspections; Drip Pans to catch minor oil leaks; Routine Pumping Out • (SA, RA, SH) Bulk Stockpiles: Placement of material at elevated portions of the site; Routine Inspections of drainage areas. 3.2 Good Housekeeping • Daily yard maintenance, and enhancement of grass and vegetation in buffer areas. Keep site clean of mud and graded for proper drainage. • Keep outside areas neat, orderly and free of trash. • Review Environmental guidelines for the proper handling of waste and refuse. • Discuss labeling of materials and proper storing requirements of those that are environmentally hazardous. • Review procedures for both routine and emergency clean-ups. • Discuss Plant Inspections, Check Lists and What to look for. 3.3 Recommended Best Management Practice A formal Best Management Practices policy should be developed by the Plant Staff and implemented through an employee training program. Particular items that to be included are: • Identify Oil leaks on or around the AC -20 tank and any appurtenances that need to be cleaned and repaired. • A written policy for proper methods of liquid material handling should be completed. This could be incorporated into an employee training program. • Structural examinations and leakage tests need to be performed on the containment structure(s) every 2-3 years. • A written proposal for the proper disposal of any fuel or oil laden stormwater as collected on the drums, sand or soil, should be developed and incorporated into a training program. Storrawater Pollution Prevention Plan (SWPPP) Barnhill Contracting, Co. — 841 Sungro Drive 3.4 Spill Prevention and Response • Review potential spill conditions and causes (i.e. lack of attention to tasks, faulty equipment, unusual weather conditions). • Discuss emergency spill response procedures and where telephone numbers are posted. • Copy and review with all employees the requirements set forth in the current Spill Prevention Control and Countermeasures Plan (SPCC) document. This should be done a minimum of once each year. • Discuss labeling of all chemicals and materials containers for quick identification and reference should an emergency occur. • Assign and review with employees specific clean up and inspection duties. 3.5 Management of Runoff Sources of pollution on this site are primarily from oil and fuel storage facilities as well as minor potential from some of the Plant Process equipment. Sand and fine rock screenings also have the potential to wash off the site and cause ditches, streams, and storm pipes to clog or increase turbidity in fish inhabited streams. This plan calls for the use of sheet flow and shallow swales to divert runoff to existing perimeter ditches, internal to the property boundaries that convey that runoff to existing sediment basins. Cleanup of said ditches and basins are proposed as a part of the upstart of this facility as well as regular inspection and maintenance. Existing Basins will be used for Erosion & Sediment control during construction of the plant site improvements. Upon completion and stabilization of the site, basins will be left in place and any skimmers or temporary measures removed. 3.6 Employee Training Personnel at all levels of responsibility will be trained in the components of the SWPPP and the SPCC. At a minimum, training will be provided on an annual basis. New personnel will receive training promptly upon assignment. All training will be documented. SECTION 4: INSPECTIONS The facility will conduct the following inspections: Routine facility inspections; Quarterly visual assessment of stormwater discharges; and Comprehensive site inspections. Storrawater Pollution Prevention Plan (SWPPP) Barnhill Contracting, Co. — 841 Sungro Drive Routine facility inspection Plant Superintendent, or specific designee will conduct routine facility inspections, using the form in Appendix E. Each structural control measure and activity area are visually inspected on a minimum annual basis, with more frequent inspections conducted as necessary to minimize the potential for a spill or release. Quarterly visual assessment Plant Superintendent, or specific designee will conduct quarterly visual assessments, using the form in Appendix D. Each drainage point is visually inspected on a quarterly basis. At least one inspection each year will be conducted when a stormwater discharge is occurring. Comprehensive facility inspection Plant Superintendent, or specific designee will conduct comprehensive facility inspections, using the form in Appendix F. Each structural control measure, activity area, and drainage point are visually inspected on an annual basis. SECTION 5: SWPPP CERTIFICATION The following certification statement must be signed and dated by the responsible signing official. This certification must be re-signed in the event of a SWPPP modification in response to a Part 3.1 trigger for corrective action.
