Introduction <br />In accordance with Title 22 of the California Code of Regulations, Chapter 15, Article 10, Section <br />66265.192 (22 CCR §66265.192), Wood Environment & Infrastructure Solutions, Inc. (Wood) conducted <br />an integrity assessment of the Holt of California waste antifreeze tank system associated with the Truck <br />Division at 1521 W. Charter Way in Stockton, California. <br />This written reassessment follows a prior assessment conducted by HDR in September of 20111. This <br />reassessment addresses San Joaquin County Environmental Health Department (Department) Class II <br />violations documented in a Large Quantity Hazardous Waste Generator Inspection Report conducted on <br />February 13, 2020, and later amended on February 26, 2020. The Department indicated that the subject <br />tank had not been reassessed by a Professional Engineer within the past five years. The regulation (22 <br />CCR §66270.11(d)) requires Holt of California to have a written hazardous waste tank system integrity <br />assessment performed by a qualified professional engineer (PE), registered in California. <br />Purpose <br />This document is the reassessment for the waste antifreeze storage tank system located behind the <br />Truck Shop at the Stockton Facility located at 1521 W. Charter Way, in Stockton, California. <br />This reassessment attests that the tank system has sufficient structural integrity; is acceptable for the <br />transferring, storing, and treating of hazardous waste (Waste Antifreeze); and the tank and containment <br />system are suitably designed to meet the requirements cited above (22 CCR §66265.192). <br />An independent, qualified PE registered in California, certified the tank system integrity reassessment in <br />accordance with 22 CCR §66270.11(d). <br />Assessment Overview <br />Wood conducted an integrity reassessment of the tank system which is used for the accumulation of <br />waste antifreeze generated by the Truck Division. The waste antifreeze tank integrity reassessment <br />consisted of the following elements: <br />●Visual examination of the tank, ports, equipment connections, piping, valves, and ancillary features <br />using the Steel Tank Institute (STI) SP001 monthly and annual inspection checklists as a means <br />for prompting documentation. <br />●Interviews with Holt personnel responsible for operating and maintaining the tank system. <br />●A chemical compatibility review regarding the materials of construction and the storage of waste <br />antifreeze. <br />●A secondary containment system assessment regarding the capacity and condition for the <br />containment of releases from the tank and ancillary equipment. <br />●A review of available tank system design drawings and records. <br />Tank System Identification <br />●Tank Name / Marking: 275-gallon waste antifreeze tank with Tank ID 1105326794 <br />●Tank Age: Based on a review of prior reporting (HDR 2011), which included input from facility <br />personnel and the manufacturer, and a review of construction drawings, the tank system was <br />delivered to the site in September of 2011. <br />●Tank Remaining Service Life: The estimated remaining service life of the tank system is at <br />least 5 years. <br />1 HDR, 2011.
