Valley Pacific Petroleum Services Stockton,CA <br /> Spill Prevention,Control,and Countermeasure Plan <br /> • Checking tank foundations and supports for signs of instability or excessive <br /> settlement; <br /> • Inspecting the tank fill and discharge pipes for signs of poor connection which could <br /> cause a discharge; <br /> • Inspecting the tank vent for obstructions affecting proper operation; <br /> • Verifying the proper functioning of the overfill prevention system; <br /> • Checking the inventory of discharge response equipment—restock as needed; and <br /> Any trained personnel noticing any problems regarding tanks, piping, containment, or <br /> response equipment must immediately report it to the Facility Manager regardless if he/she <br /> noticed the problem(s) during the walkthroughs or not. Trained personnel must repair <br /> visible oil leaks from tank walls, piping, or other components as soon as possible to <br /> prevent a larger spill or an oil discharge to navigable waters. Trained personnel will <br /> remove pooled oil immediately upon discovery. <br /> The Facility Manager or their representative must sign the written monthly inspection <br /> records and must maintain the records with this SPCC Plan for a period of three years. <br /> C. Annual Inspections <br /> Trained facility personnel perform a more thorough written inspection of facility equipment <br /> on an annual basis using the checklist provided in Appendix D of this Plan before the first <br /> major storm event of the season in order to verify the imperviousness and proper <br /> functioning of the drainage control systems: the shut-off valve and USC. This annual <br /> inspection complements the monthly inspection described above. The Facility Manager <br /> must sign the written yearly inspection records and must maintain the records with this <br /> SPCC Plan for a period of three years. <br /> D. Tank Inspections <br /> In addition to the above facility personnel's monthly and annual, a certified inspector <br /> periodically evaluates all tanks using the Steel Tank Institute (STI) Standard for the <br /> Inspection of Aboveground Storage Tanks, SP-001, 2015 version. <br /> All tanks are field-constructed. The design and construction of all bulk storage containers <br /> are compatible with the characteristics of the oil product they contain, temperature, and <br /> pressure conditions. The appropriate aboveground supports, which are suitable for the <br /> steel piping located between fixed aboveground bulk storage tanks, minimize erosion and <br /> stress. Specially designed seismic shut-off valves are also in place. The shell thicknesses <br /> of all tanks are less than one-half inch. As discussed in the American Petroleum Institute <br /> (API) Standard 653 Tank Inspections, Repair, Alteration, and Reconstruction (API-653), <br /> brittle fracture is not a concern for tanks, which have a thickness of less than one-half inch. <br /> This is the extent of the brittle fracture evaluation for these tanks. <br /> 0 <br /> 10 <br />
