SPCC for Antonini Enterprises Lathrop Facility (vi) Aboveground tank periodic integrity testing: 112.8(c) (6) Test or inspect each aboveground container for integrity on a regular schedule and whenever you make material repairs. Determine, in accordance with industry standards, the appropriate qualifications for personnel performing tests and inspections, the frequency and type of testing and inspections, which take into account container size, configuration, and design(such as containers that are:shop-built, field-erected, skid-mounted, elevated, equipped with a finer, double-walled, or partially buried). Examples of these integrity tests include, but are not limited to: visual inspection, hydrostatic testing, radiographic testing, ultrasonic testing, acoustic emissions testing, or other systems of non-destructive testing. You must keep comparison records and you must also inspect the container's supports and foundations. In addition, you must frequently inspect the outside of the container for signs of deterioration, discharges, or accumulation of oil inside diked areas. Records of inspections and tests kept under usual and customary business practices satisfy the recordkeeping requirements of this paragraph. Integrity testing. The facility and all AGTs are new and were recently installed (2013). No deterioration or leakage was observed at the time of the site inspection. The two large bulk storage tanks AGT 1 and AGT 2 are continuously monitored by electronic inventory tracking system (Veeder-Root, TLS 300). The system allows the user to track instantaneous fuel quantities as well as monitor the secondary interstitial space of each tank for potential breech of the interior tanks. The waste oil collection tank (AGT 6) can be manually tested for leaks within the primary tank. The secondary containment tank for this AGT has a cap on top that can be opened. A visual inspection or dip stick can be used to inspect for possible leaks. The fresh oil tank (AGT 7) has a leak indicator that can be visually inspected for indications of a leak within the primary tank. Inspections. The Fleet Manager performs inspections of the equipment no less than once per week. During inspections, the outside of the tanks and exposed piping and supports are inspected for leaks and signs of deterioration, and for leaks inside of the secondary containment. A copy of the inspection form used is included in Appendix B. Inspection forms are stored with the SPCC in the office of the Safety Supervisor. (vii) Control of leakage through internal heating coils: 112.7(e)(2) Bulk storage tanks (onshore); (excluding production facilities). (vii) To control leakage through defective internal heating coils, the following factors should be considered and applied, as appropriate. (A) The steam return or exhaust lines from internal heating coils that discharge into an open water course should be monitored for contamination, or passed through a settling tank, skimmer or other separation or retention system. (B) The feasibility of installing an external heating system should also be considered. None of the tanks are equipped with internal heating coils. (viii) Tank installation fail-safe engineered: 112.7(e)(2) Bulk storage tanks (onshore), (excluding production facilities). (viii) New and old tank installations should, as far as practical, be fail safe engineered or updated into a fail-safe engineered installation to avoid spills. Consideration should be given to providing one or more of the following devices: (A) High liquid level alarms with an audible or visual signal at a constantly manned operation or surveillance station;in smaller plants, an audible air vent may suffice. -14-
