Corporon, P.G. North Carolina Division of Water Resources Raleigh Regional Office—Attn: NPDES Unit 1617 Mail Service Center Raleigh, North Carolina 27699-1617 Subject: Site Management Practices and Spill Response Plan Speedway#6973 13960 Capital Boulevard Youngsville, North Carolina NPDES Permit No.: NCO087912 Dear Mr. Corporon, On behalf of Speedway, LLC (Speedway), and in compliance with Section A.(2.) of their National Pollutant Discharge Elimination System (NPDES) Permit No. NC0087912, Mid-Atlantic Associates, Inc. (Mid-Atlantic) has prepared this Site Management Practices and Spill Response Plan (MPSRP). The objective of this plan is to outline the strategies and procedures implemented at the site to minimize the generation and discharge of wastewater at the diesel dispenser islands, and to ensure swift and effective response to fuel spills, thereby protecting the environment. Site Management Practices The following practices are currently implemented or will be carried out to reduce both the quantity and contamination level of wastewater generated at the diesel fuel islands, which is ultimately treated and discharged: 1. Canopy Coverage: The diesel dispenser islands are shielded by a canopy to reduce exposure to rainfall, thereby minimizing the amount of contaminated runoff. 2. Drainage System: A frame and grate system, connected to a grit separator and oil/water separator, has been installed to limit stormwater infiltration into the wastewater system. 3. Spill Kits and Dry Absorbents: The facility is equipped with spill kits and dry absorbents, maintained in accessible locations as per Speedway personnel guidelines. 4. Spill Response: Spills or leaks resulting from vehicle fueling operations are promptly cleaned using dry absorbents to prevent contamination. 5. Break-Away Hoses: Dispensers are fitted with "break-away" hoses to prevent fuel spills caused by vehicles driving off with the nozzle still attached.

Routine Inspections: Regular inspections of the diesel dispenser islands, collection system, and oil/water separator are conducted by the designated Operator-in- Responsible-Charge (ORC) or their backup. 7. Periodic Pumping: The oil/water separator is periodically pumped out to maintain adequate capacity and functionality. Spill Response Procedures To effectively manage and mitigate fuel spills at the site, the following procedures will be executed: 1. Immediate Cleanup: Minor spills and leaks during vehicle fueling are addressed immediately using dry absorbents. 2. Source Control: The source of the spill will be quickly identified and secured, whether by shutting down or disconnecting the fuel source. 3. Containment: In cases where a spill surpasses the capacity of the frame and grate system, immediate action will be taken to prevent the spread of fuel. This includes isolating the downgradient storm drain located in the southeastern corner of the site to prevent fuel from entering the drainage system. Containment measures may include the use of spill booms, absorbent pillows, or oil-dry dams. Notification and Reporting: The on-site Speedway employee will contact the Operations 24/7 Speedway Store Support Center. The Store Support Center is responsible for alerting the appropriate emergency response teams who will report the spill to relevant government agencies. Evaluation, Inspection, and Monitoring of the Oil/Water Separator The oil/water separator is a critical component of the spill containment and wastewater treatment system at the site. Proper evaluations and inspections are essential to ensure its effective operation and to prevent environmental contamination. This section outlines the procedures for evaluating and inspecting the oil/water separator. Evaluation Initial Evaluation: • Purpose: To assess the current condition and performance of the oil/water separator and to establish a baseline for future inspections and maintenance. • Procedure: o Conduct a visual inspection of accessible exterior portions of the separator to check for signs of wear, damage, or corrosion. o Evaluate the separator's efficiency by testing the quality of the treated water exiting the unit. This can be done by collecting samples and analyzing them for oil content and other contaminants. o Review the manufacturer's specifications and maintenance history to ensure 0 Mid Atlantic Site Management Practices and Spill Response Plan November 1, 2024 13960 Capital Boulevard Page 3 Youngsville, North Carolina the separator is operating within its designed parameter Performance Evaluation: • Purpose: To regularly assess the operational efficiency of the oil/water separator to ensure it is effectively removing oil and other contaminants from wastewater. • Procedure: o Monitor the quality of the effluent by conducting periodic water quality tests. These tests should measure oil concentration, total suspended solids (TSS), and other relevant parameters. o Compare the results against regulatory standards and manufacturer specifications to determine if the separator is performing adequately. o If performance issues are detected, conduct a detailed assessment to identify the root cause and implement corrective actions. • Frequency: Quarterly, or more frequently if required by local regulations or if previous evaluations have indicated potential issues. Inspections: Routine Inspections: • Purpose: To detect early signs of problems and ensure the separator is functioning correctly. • Procedure: o Visually inspect the oil/water separator for signs of leaks, cracks, or other damage. o Check the oil level in the separator and ensure it is within the acceptable range. o Inspect the inlet and outlet pipes for blockages or buildup of materials that could impede flow. o Verify that control panels, alarms, and monitoring devices are operational, if applicable. • Frequency: Monthly, with additional inspections following heavy rainfall or a significant spill event. Detailed Inspections: • Purpose: To conduct a comprehensive examination of the separator, including internal components that may not be visible during routine exterior inspections. • Procedure: o Shut down the separator and remove accumulated oil and sludge according to manufacturer guidelines and environmental 0 Mid Atlantic Site Management Practices and Spill Response Plan November 1, 2024 13960 Capital Boulevard Page 4 Youngsville, North Carolina regulations. o Inspect the internal baffles, plates, and coalescing media for signs of wear, fouling, or damage. o Clean the separator's internal components as necessary to maintain efficiency. o Inspect seals and gaskets and replace them if signs of deterioration are observed. • Frequency: Biannually or as recommended by the manufacturer. Manual Monitoring: • Purpose: To provide a hands-on assessment of the separator's performance. • Procedure: o Manually check the oil/water separator's effluent quality by taking samples and visually inspecting them for signs of oil contamination. o Record the oil levels in the separator and compare them with historical data to identify unusual trends. • Frequency: Biannually, with additional checks following significant operational changes or spill events. We trust that this plan meets the requirements outlined in Section A.(2.) of Speedway's NPDES Permit for the Youngsville facility.
