Spill Prevention,Control,and Countermeasure Plan Love's/Speedco#944,Ripon,California Page 6of13 anteagroup 4.5 Discharge Prevention Measures [40 CFR 112.7(a)(3)(ii)] This section describes spill prevention measures and procedures for routine handling of products at the facility. Measures the facility takes to prevent discharges include the following: a. Employees receive training in the prevention of spills, as well as control and countermeasure procedures. Employee training records are maintained in Appendix A or kept on file with the SPCC Plan. b. A Tank Inspection Record is completed by a trained employee. The record documents the inspection of the ASTs, dispensers, maintenance areas, valves, gauges and alarms. Tank inspection records are maintained in Appendix B or kept on file with the SPCC Plan. c. Written procedures are maintained and followed for loading and unloading operations for oil transfers. Loading/Unloading Procedures are presented in Appendix C. d. Equipment is maintained in good condition to minimize the risk of an oil discharge due to equipment failure.A comprehensive preventative maintenance program is implemented at the facility. 4.6 Discharge/Drainage Controls [40 CFR 112.7(a)(3)(iii)] This section describes discharge or drainage controls such as spill containment materials and secondary containment around containers and other structures,equipment,and procedures for the control of a discharge. • An oil and water separation unit is used to treat wastewater at the Facility, prior to discharge to a municipal treatment system. The units are contained within the secondary containment structure and receive influent from the main sump (also located within the secondary containment structure). Floor surfaces of the Facility are sloped toward floor drains which flow into the sump system. The capacity of the sump is approximately 400 gallons. As oil and water accumulate in the sump system, pumps are activated which transfer the sump contents to the oil/water separator. The oil/water separator is designed with three compartments and has an approximate flow through capacity of 300-gallons. The unit transfers oil to the used oil tank (Tank 1) and transfers water to the municipal sewer. An independent contractor is under agreement to maintain and clean this equipment, per the manufacturer's recommendations. The air compression system used to operate the tank and oil/water separator pumps is shut off at the close of each business day.This practice prohibits the ability of equipment malfunctions when the Facility is not manned outside of business hours. The OWS is a flow through wastewater treatment unit and therefore is exempt from SPCC oil storage container regulation. • Tanks 1-5 are situated within a three-foot deep concrete secondary containment with an approximate holding capacity of 11,420 gallons. Any collection of liquid would be pumped into the main sump system leading to the oil and water separator. • Tanks 6-7 and the various other small oil containers are located inside the lubrication bays. Any spills or leaks would drain to the main sump via the floor drains. • Discharges resulting from a leak or spill would be contained using spill containment kits.The containment kits are used to capture spilled oil and prevent the oil from entering sanitary sewers and/or storm water outfalls.An oil release flowing toward an on-site storm water or sanitary sewer drainage system would be controlled with containment socks and absorbents.
