SPILL PREVENTION,CONTROL AND COUNTERMEASURE OIL PRODUCTION FACILITY REQUIREMENTS—ANIMAL FATS, PLAN(SPCC) OILAND VEGETABLE OILS Pacific Ethanol,Stockton. 7. OIL PRODUCTION FACILITY REQUIREMENTS -ANIMAL FATS, OIL AND VEGETABLE OILS 7.1 Facility Drainage [112.12(B)] 7.1.1 Close and Seal Drains There are six diked areas at the Facility. The trench sumps and containment system contain drainage for the buildings in the Facility. If accumulated oil is observed in containment structures during monthly inspections, it will be removed in accordance with approved methods. PES will investigate to determine the source of the oil accumulation. Once identified, Pacific Ethanol will make repairs to eliminate the oil leak. 7.1.2 Inspect Drainage Systems Drainage systems are inspected monthly. If accumulated oil is observed during the inspection, it will be removed in accordance with approved methods. PES will investigate to determine the source of the oil accumulation. Once identified, PES will make repairs to eliminate the oil leak. 7.2 Bulk Storage Containers [112.12(C)] 7.2.1 Container Compatibility with Contents and Storage Conditions (112.12(c)(1)] The containers used for the storage of oil are compatible with storage conditions and the materials they hold. 7.2.2 Secondary Containment[112.12(c)(2)] The storage tanks (including denatured ethanol and corn oil) have concrete secondary containment berms and trenches. Spillage from any of the tanks at the Facility will drain into the Facility's sump system. The sump system will thus effectively serve as a secondary containment system and will prevent any release from reaching navigable waters. 7.2.3 Inspections(112.12(c)(6)] Bulk storage containers will be inspected by the Facility in accordance with the requirements of 112.12(c)(6) as applicable. 7.2.4 Discharge Avoidance Through Good Engineering Practices[112.12(c)(8)] ASTs at the Facility are equipped with high liquid level and low liquid level alarms to notify personnel. 7.3 Facility Transfer Operations [112.12(D)] The provisions of 40 CFR 112.12 are nearly identical to those in 40 CFR 112.8. Section 112.8 covers requirements associated with petroleum and Section 112.12 deals with animal fats, oils and greases, and vegetable oils. 7.3.1 Protection of Buried Piping(112.12(d)(1)] There are no buried oil-containing pipelines at the Facility. The analysis of this section was determined to be similar to the discussion in Section 6. www erm.com Project No:0453993 Pacific Ethanol 28 September 2018 Page 29
