Spill Prevention, Control and Countermeasure Plan Tesla Treatment Facility Page 34 of 45 3.0 PLAN REQUIREMENTS FOR PETROLEUM OIL-BASED FACILITIES [40 CFR§112.8 THROUGH 40 CFR§112.111 Section 3.0 of this SPCC Plan provides specific provisions of the Part 40 CFR§112—Oil Pollution Prevention(SPCC Rule)that apply to the Emergency Power Generation Facility where diesel fuel and engine oil are stored, handled, and maintained. Facility details are presented in Figure A-5.2 through Figure A-5.6 in Appendix A. 3.1 SPCC Plan Requirement [40 CFR§112.8(a)] This SPCC Plan was prepared to meet the general requirements in Section 40 CFR§112.7, and specific discharge prevention and containment in Section 40 CFR§112.8 of the SPCC Rule. 3.2 Facility Drainage [40 CFR§112.8(b)] The following addresses facility drainage requirements in 40 CFR§112.8(b) of the SPCC Rule. 3.2.1 Drainage from Diked Areas [40 CFR§112.8(b)(1)] 40 CFR§112.8(b)(1) of the SPCC Rule is not applicable because there are no diked oil storage areas at the Tesla Treatment Facility. 3.2.2 Allowable Drainage Valves [40 CFR§112.8(b)(2)] 40 CFR§112.8(b)(1) of the SPCC Rule is not applicable because there are no diked oil storage areas at the Tesla Treatment Facility. 3.2.3 Facility Drainage System Design [40 CFR§112.8(b)(3)] Facility drainage is shown in Figure A-4.3 and Figure A-4.4 in Appendix A. Any significant spill or discharge that occurs from the tanks,piping,valves, and appurtenance not retained by secondary containment, not contained by spill response efforts, or not pooled or retained by the ground surface at the discharge source, can potentially collect and flow by gravity into the stormwater drainage system that services the facility. At the Emergency Power Generation Facility, stormwater runoff and surface drainage is diverted via storm drain inlets,culverts and underground piping to the storm drain inlet located immediately south of the loading/unloading area. Drainage collecting in this storm drain inlet flows southward via a 15-inch underground stormwater sewer pipe and discharges into the retention basin located along the south side of the Tesla Treatment Facility. The retention basin is designed to collect all stormwater runoff and surface drainage from the Tesla Treatment Facility to allow for retention and sedimentation before drainage continues eastward via an underground sewer pipe to discharge off the property. Drainage then continues downslope along drainage channel towards Interstate Highway I-580, located approximately 0.6 miles east of the Tesla Treatment Facility. 3.2.4 Drainage Diversion System [40 CFR§112.8(b)(4)] 40 CFR§112.8(b)(4) of the SPCC Rule is not applicable to the Tesla Treatment Facility.
