Spill Prevention, Control and Countermeasure Plan Tesla Treatment Facility Page 35 of 45 3.2.5 Drainage Water Treatment [40 CFR§112.8(b)(5)] 40 CFR§112.8(b)(5) of the SPCC Rule is not applicable to the Tesla Treatment Facility because drainage water is not treated at the facility. 3.3 Bulk Storage Containers [40 CFR§112.8(c)] Table 2-1 of this SPCC Plan summarize the construction, volume, and content of oil storage containers at the Tesla Treatment Facility. Appendix A presents a physical layout of the facility and detail diagrams of the tanks and equipment that are subject to the SPCC Rule. 3.3.1 Container Compatibility [40 CFR§112.8(c)(1)] Consistent with 40 CFR§I 12.8(c)(1), the bulk storage tanks and generators' day tanks are built to the Underwriters Laboratory Standards 2085 and 142, National Fire Protection Association (NFPA) Standard 30, and American National Standards Institute (ANSI) B137.1-1971. Installed in 2011, the dual-wall steel storage tanks were manufactured by Modern Welding Company of West Sacramento, California. The tanks were built with a design pressures and temperatures exceeding operating pressures and temperatures The secondary containment of each tank is designed to contain 110% of the volume of the primary tank shell (PCL, October 6, 2011). Fuel Oil Service (FOS) and Fuel Oil Return (FOR) piping extends from the bulk storage tanks to the generators' day storage tanks. The FOR and FOS piping is supported by angle brackets and are sloped such that a low point and sump are located at each end of the piping,the sump equipped with a leak detection sensor. Those sections of the FOR and FOS piping that are underground are double-walled with the outer shell designed to contain 110%of the inner shell and sloped to a low point and sump equipped with leak detection sensor. Aboveground FOR and FOS piping is of single-wall construction, supported by angle brackets, and sloped such that a low point and sump are located at each end of the piping, the sump equipped with a leak detection sensor. Both the double-walled underground piping and single-wall aboveground piping are engineered to drain any leaked product into sumps equipped with electronic leak detection sensors. There is also aboveground fuel piping that extends from each generator's day tank to the generator's engine, single-walled piping of short length and housed in the generator's enclosure. The generators' day tanks have leak detection sensors and are equipped with drip or leak basins. Vent piping and fittings were designed to meet ANSI B16.3 (Class 150 and 300), and the American Society for Testing and Materials (ASTM) A53 and A120, and industry standards for fuel delivery systems (PCL, October 6, 2011). Piping between the aboveground bulk storage tanks is made of steel and placed aboveground on appropriate supports designed to minimize erosion and stress. The underground section of piping between the tank area and generators is double contained and designed to slope to the containment sumps, each sump is equipped with continuous electronic monitoring. Any release in the underground piping system will trigger an alarm and close the supply piping solenoid valves at each tank, stopping the flow of fuel through the system.
