Industry Standards Testing <br /> Williams Tank Lines <br /> 1477 Tillie Lewis Drive, Stockton, CA 95206 <br /> Industry Standards testing was performed on May 7, 2020, as prescribed by the <br /> guidelines of the Steel Tank Institute and the requirements of the SPCC Plan Section <br /> 112.8(c)(6). <br /> § 112.8 Spill Prevention, Control and Countermeasure Plan requirements for onshore <br /> facilities (excluding production facilities). <br /> (c) Bulk storage containers. <br /> (6) Test each aboveground container for integrity on a regular schedule, and whenever <br /> you make material repairs. The frequency of and type of testing must take into account <br /> container size and design (such as floating roof, skid mounted, elevated, or partially <br /> buried). You must combine visual inspections with another testing technique such as <br /> hydrostatic testing, radiographic testing, ultrasound testing, acoustic emissions testing, <br /> pneumatic pressure or another system of nondestructive shell testing. You must keep <br /> comparison records and you must also inspect the container's supports and foundations. <br /> In addition, you must frequently inspect the outside of the container for signs of <br /> deterioration, discharges, or accumulation of oil inside diked areas. Records of <br /> inspections and tests kept under usual and customary business practices will suffice for <br /> purposes of this paragraph. <br /> Industry Standards testing was performed utilizing a Certified Ashcroft T5500 SS 0-5 psi <br /> gauge. Calibration of the certified testing device was performed and passed on May 7, <br /> 2020, prior to conducting the non-destructive test evaluations. <br /> Industry Standards testing consisted of pneumatic pressure testing of the secondary <br /> containment space. No defects were observed throughout all of the oil product tanks and <br /> the systems are in compliance with CFR 112.8(c)(6) testing requirements. <br /> Test frequency is based on a five-year basis as the tank system is a Category II. <br /> Gary Reeves <br /> Certified Steel Tank Institute Level I <br /> & Level II Tank System Inspector at <br /> SP001 #11111 <br /> NDT-UT#0001 <br /> ASNT-TC-1A#073128 <br /> Certified Environmental Professional , <br /> REA II #30349 <br /> Gary Reeves, LLC <br />
