Spill Prevention, Control, and Countermeasure Plan Swiff Transportation, Inc. — Lathrop, California ENSAFE Section 14.- Bulk Storage Tanks/Secondary Containment February 2016 INDUSTRY STANDARD CONSIDERATION: In addition to the general oil loading/unloading guidelines outlined in Section 5.2.10, Swift personnel should be cognizant of the following overfill protection guidelines outlined in API RP 2350 Section 2.2.2: (1) If an electrical or mechanical failure occurs that affects the level detectors, product receipt shall stop and not recommence until (a) the detectors are functioning properly or (b) manual operations and procedures are implemented (as outlined In Section 11.0), (2) When only one detector is used, this high -high level detector shall be located at or above the safe fill levels and shall alarm/signal to provide sufficient time to shut off or divert product flow before the overfill is reached. (3) When used for overfill protection, the high -high level detector shall be independent of the automatic tank gauge system to provide greater reliability and to comply with the requirements of NFPA 30-2012 (Section 21.7). This section applies to ASTs at terminals receiving Class 1 liquids from mainline pipelines and marine vessels. (Note., A Class 1 liquid is a liquid with a flash point below 100°F [e.g., gasoline].) (4) If a tank is to be filled above its normal fill level (normal capacity) up to its safe fill level (tank rated capacity), a trained and qualifled person shall be assigned by the operator to be present at the tank. API does not recommend routinely filling a tank above the safe rill level due to the increase in overfill risk. (5) Any shutdown or diversion procedures should be compatible with the transporters operations to prevent consequential damage, such as hydraulic shock or over pressuring the piping system. 14.9 Observation of Disposal facilities for Effluent Discharge 112.8(c)(9); You must observe effluent treatment facilities frequently enough to detect possible system upsets that could cause a discharge as described in §112.1(b). There is no effluent discharge to navigable waters at Swift (the OWS discharges to the sanitary sewer); therefore, this section is not applicable. 14.10 Visible Oil teak Corrections from Tank Seams and Gaskets 112.8(c)(10): You must promptly correct visible discharges which result in a loss of oil from the container, induding but not limited to seams, gaskets, piping, pumps, valves, rivets, and bolts. You must promptly remove any accumulations of oil in diked areas. Currently, potential oil leaks from tank systems are identified during the daily operations. Operational personnel are trained and instructed to notify the terminal contacts listed in Section 2,2 if these conditions are observed. The terminal and/or service manager is responsible for using spill control materials to remove any spilled oil and for ensuring that AST seams/gaskets are repaired promptly. 14-6
