Used Oil Tank <br /> Containment Integrity Report <br /> For <br /> HMT Inspection <br /> Tracy Express Carwash & Lube <br /> Tracy, CA January 17,2019 <br /> Page 9 of 34 <br /> 3.0 EVALUATION FOR CCR COMPLIANCE - USED OIL <br /> STORAGE TANK <br /> SUMMARY OF CA DTSC EVALUATION PER TITLE 22 CCR, Part 66265.191: <br /> Pursuant to Title 22, §66265.191 of the California Code of Regulations, the following <br /> highlights provide a summary evaluation of the major areas of concern regarding the <br /> aboveground Used Oil Storage Tank under those regulations: <br /> 1. The primary design basis utilized in the construction of this tank is normal <br /> industry practice for horizontal aboveground storage tanks on structural supports. <br /> 2. The product in the tank includes used oil that is temporarily stored prior to <br /> recycling off-site. <br /> 3. Corrosion protection measures directly applicable to the tank involve coatings on <br /> the tank (paint or material resistant to degradation). The walls of the tank that <br /> are in contact with the stored liquid are all of carbon steel construction, resistant <br /> to corrosion from oil. These materials continue to be resistant to the stored liquid <br /> based on current condition and age. <br /> 4. The Used Oil Tank has been on this site and present location and has been in <br /> operation since 1996. The tank and connections show no evidence of <br /> deterioration at this time. If properly maintained now and into the future, the tank <br /> and connections should have a remaining useful life of 5 years or more based on <br /> past history and current condition. The next inspection interval for the tank and <br /> connections has been established at approximately 5 years based on the need to <br /> verify continuing integrity of the material in contact with the stored liquid (ref. <br /> corrosion rate calculations in Table B included herein). <br /> 5. Flow into the tank is controlled manually using collection pans and a manual <br /> pneumatic pump into the tank. This equipment is suitable for continued service <br /> until the next out-of-service or maintenance cycle. <br /> 23264311 Used Oil Tank-DTSC Report r4(Rev 0) 2/7/2019 2:38 PM <br />
