v ' <br /> Nondestructive Metal Thickness Testing MAR 0 3 2016 <br /> Norcal Transport Refrigeration - Stockton, Ew"!RONMENTAL <br /> Tu rZ�eF-I^Tgar-A4T <br /> Metal thickness testing and evaluation was performed on February 29, 2016, as per <br /> Steel Tank Institutes guidelines and the requirements of the SPCC Plan Section <br /> 112.8(c)(6). <br /> § 1.12.8 Spill Prevention, Control, and Countermeasure Plan requirements for <br /> onshore 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 inspection with another testing technique such as <br /> hydrostatic testing, radiographic testing, ultrasonic testing, acoustic emissions testing, <br /> or another system of nondestructive shell testing. You must keep comparison records <br /> and you must also inspect the container's supports and foundations. In addition, you <br /> must frequently inspect the outside of the container for signs of deterioration, <br /> discharges, or accumulation of oil inside diked areas. Records of inspections and tests <br /> kept under usual and customary business practices will suffice for purposes of this <br /> paragraph. <br /> Metal thickness testing was performed utilizing a certified Danatronics FMC-09DL- <br /> CW Digital Ultrasonic thickness gauge. Calibration of the testing unit was performed <br /> on February 29, 2016, prior to conducting certified nondestructive metal thickness <br /> testing_ <br /> Testing consisted of A point measurements per square foot. All aboveground steel <br /> fuel storage tanks were evaluated from the lower portion of the flank to at or above <br /> the midline. All report readings are the average thickness readings per square foot <br /> and an average for the entire side was reported. No defects were observed and the <br /> oil product tanks are reported to be in compliance with CFR 112.8(c)(6) <br /> requirements. <br /> Testing frequency is recommended to be on a five year basis for the Certified UL <br /> 142 #2 Diesel Fuel Storage tank to meet CFR 112.8(c)6) requirements. <br /> Gary Reeves, <br /> 4,"-R"eA.eS <br /> Certified Steel Tank Institute Level 1 <br /> & Level 2 Tank and System Inspector. <br /> SPOO1 Level II #11111 <br /> NDT UT Level III #001 <br /> ASNT-TC-1A # 01328 <br />
