SPCC Plan — Williams Tank Lines - Stockton, CA <br /> 301 <br /> Direction Rate of Flow & Total Quantity of a Potential Discharge <br /> 40 CFR 112.7 b <br /> The facility's oil product storage system is securely located and the main tank for <br /> diesel fuel storage is a 12,000 gallon single wall steel tank. The tank is designed to hold <br /> oil products and any failure of the 12,000 gallon tank will be retained within the spill <br /> containment wall. No oil product will be allowed to drain from the containment area. The <br /> waste oil product tanks are 220 gallon IBC totes that are securely installed on a 700 <br /> gallon spill pallet. Any failure of the IBC tote system will be contained within the spill <br /> pallet and no oil product will be released. Any piping, pump or valve failure outside the <br /> containment area will be contained on site and drain into the two compartment oil/water <br /> separator located in northwest of the IBC tote storage tank area. The new motor oil and <br /> other oil product storage tanks are securely maintained inside the truck shop. Any <br /> discharge from these oil product storage tanks will be controlled inside the truck shop. <br /> All pipe endings are plugged or have adapters and caps and are sealed. No oil <br /> product line has the free ability to drain. <br /> The truck unloading area is on the west side of the facility and located on cement <br /> and asphalt. If a failure of the tanker truck occurred, it is expected that the driver would <br /> initiate controls to mitigate the discharge of oil products. Each compartment has a <br /> maximum of 5,000 gallons and a discharge as a result of a broken or ruptured delivery <br /> hose can be mitigated by the driver promptly closing the any manifolded delivery valves. <br /> Any discharge from the truck or hose will flow onto the asphalt and will be contained <br /> within the designed control system on the asphalt area. <br /> The retained fuel storage tank is contained within a steel containment pan that is <br /> designed to contain the entire oil product capacity. In the event of the tank failure any <br /> and all oil product discharge will be securely contained within the containment pan. <br /> The oil products stored in 55 gallon drums and used oil products within the truck <br /> shop room and/or adjacent to the truck shop are secured and safely placed. Any spill or <br /> discharge from the oil product containers in the truck shop room will remain within the <br /> confinement of the truck shop room. The floor drain is terminal to the room and any spill <br /> or discharge will be mitigated within the room area. All drums adjacent to the truck shop <br /> are located on spill pallets. No oil products will freely flow from any nozzle or discharge <br /> gun within the facility. All oil product potential discharges are designed to flow into the <br /> drains leading to the three part oil/water separator and precipitation is designed to drain <br /> to the drains that lead to the detention basin, located at the southwest side of the <br /> facility. <br /> The site' drainage system is designed to control the flow of any liquid discharge <br /> and Williams Tank Lines management is committed to controlling any potential <br /> discharge and will insure that any spill or discharge is addressed safely and securely. <br /> George W.Lowry Oil, Inc. 23 <br /> Environmental Services Division <br /> 2010 <br />
