Spill Prevention, Control and Countermeasure Plan Tesla Treatment Facility Page 41 of 45 4.0 PLAN REQUIREMENTS FOR VEGETABLE OIL-BASED EQUIPMENT [40 CFR§112.12 THROUGH 40 CFR§112.151 Section 4.0 of this SPCC Plan provides specific provisions to meet SPCC Rule provisions that apply to tanks used for the storage of vegetable oil-based fluids as is the case with the unit-type substation transformer located outside of the Electrical Building. Facility details are presented in Figure A-6.1 and Figure A-6.2 in Appendix A. Because the substation transformer tank is filled with a vegetable oil-based fluid, and not a petroleum hydrocarbon-based fluid, the substation transformer is exempt from the state's APSA. The substation transformer has a steel tank of 723-gallon capacity that is used for the storage of the transformer's insulating or dielectric fluid, Envirotemp® FR3TM. Envirotemp® FR3TM, an electrical insulating or dielectric fluid based on a natural ester derived from 100% renewable vegetable oils, is formulated from seed oils and performance enhancing additives (Cargill, 2016). The product contains no polychlorinated biphenyls (non-PCBs),no petroleum,halogens, silicones or sulfurs. The fluid is biodegradable,non-toxic, sustainable,recyclable, and possesses a high fire point(K class). Envirotemp® FR3TM is Approved by FM Global and Classified by Underwriters Laboratories (UL) as a Less-Flammable Dielectric Liquid for use in complying with the National Electric Code (NEC) and insurance listing requirements. Compatible with standard transformer construction materials and components, Envirotemp® FR3TM provides improved fire safety, transformer life/loadability and environmental benefits that are superior to mineral oil and unsurpassed by any other dielectric coolants in the marketplace (Cargill, 2016). 4.1 SPCC Plan Requirement [40 CFR§112.12(a)] This SPCC Plan was to meet the general requirements in Section 40 CFR§112.7 and specific discharge prevention and containment in Section 40 CFR§112.12 of the SPCC Rule. 4.2 Facility Drainage [40 CFR§112.12(b)] Drainage associated with the substation transformer is discussed below. 4.2.1 Drainage from Diked Areas [40 CFR§112.12(b)(1)] 40 CFR§112.12(b)(1)of the SPCC Rule is not applicable because there are no diked areas or diked containment around the substation transformer. 4.2.2 Allowable Drainage Valves [40 CFR§112.12(b)(2)] 40 CFR§112.12(b)(2)of the SPCC Rule is not applicable because there are no diked areas or diked containment around the substation transformer.
