1.0 EXECUTIVE SUMMARY <br />An API Standard 653 In-Service inspection of Canary Renewables Corp. 3134A Bio <br />Diesel Storage located at the Canary Renewables Corp. Site in Stockton, California <br />was conducted on 02/21/23. This inspection was conducted to collect data in order to <br />evaluate the mechanical integrity and fitness for continued service of the tank. The roof, <br />three shell courses and floor are all constructed out of 0.250" A36 grade carbon steel. <br />The tank is supported on a concrete slab foundation, fastened with anchor chairs. <br />Intersecting all three above ground storage tanks in the East/West direction the <br />concrete slab foundation appears to be heaving, causing a loss of embedment of the <br />anchor chair bolts. It is recommended to have a foundation engineer evaluate the root <br />cause of the anchor bolt release. <br />The roof vacuum/venting valve and relief valve are in a serviceable condition and do <br />not appear to contribute to lifting, further causing foundation anchor release. <br />The tank meets the requirements for 20 year initial internal inspection interval due to an <br />acceptable Release Prevention Barrier system installed to contain tank contents in <br />case of accidental release. <br />The tank roof has coating failure that will need to be addressed. Coating failure in <br />various locations around nozzles and tank chime require local coating repairs. <br />CODE STEEL performed all Non-Destructive Examinations as per API 650, Section 8. <br />Please refer to the results and recommendation sections of this report for other minor <br />discrepancies and recommendations that were identified during the course of this <br />inspection. Please note that it is the responsibility of the owner to review the inspection <br />findings, recommendations, and requirements to establish a repair scope if needed, <br />and determine the appropriate timing for repairs, monitoring, and maintenance activities <br />(Ref API 653, Para. 6.9.3.2). <br />Required Next Inspections per API-653: <br />UT Thickness: February 2038 <br />External: February 2028 <br />Internal: February 2034
