Spill Preyentlon, Control, and Countermeasure Plan Swift Transportation, Inc. — Lathrop, California ENSAFESection 14.• Bulk Storage Tanks/Secondary Containment February 2016 14.5 Corrosion Protection of Partially Buried Metallic Tanks 112,8(c)(5): You must not use partially buried or bunkered metallic tanks for the storage of oll, unless you protect the buried section of the tank from corrosion. You must protect partially buried and bunkered tanks from corrosion by coatings or cathodic protection compatible with local soil conditions. No partially buried metallic tanks are present at Swift; therefore, this section is not applicable. 14.6 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. You must 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 liner, 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 Although 40 CPR 112.8(c)(6) requires integrity testing for each aboveground storage container, the U.S. PPA, March 2004 industry settlement, established exceptions to the regulation. These rules direct the engineer to recommend integrity testing based on industry standards. For the type of tanks at the Swift terminal, STI SP001 industry standard applies. This industry standard sets integrity testing requirements based on AST type, size, installation, corrosion rate, and previous inspection history to develop a schedule of applicable types of inspections for each AST. Visual Inspections and In#eigrity Testing As summarized in Table 7-1, the oil containers included in this SPCC Plan are subject to monthly and annual visual inspections using the Inspection Checklist in Appendix D. Completion of the monthly inspections must be tracked and records kept by the service manager. The split used oil and new oil AST is classified as a Category 1 system that is less than 5,000 gallons. In accordance with Table 5.4 of STI 5P001, periodic (monthly and annual) visual inspections are the only type of integrity testing required for the facilities ASTs that are less than 5,000 gallons. The three, 10,000 -gallon bulk diesel ASTs are classified as a Category I system that is greater than 5,000 gallons. In accordance with Table 5.5 of STI SP001, a formal external inspection by a certified STI inspector is required every 20 years. In addition, periodic (monthly and annual) visual inspections are required for these three ASTs. 14-3
