The Dormant Oil Tank,if it has petroleum product in any concentration would be understate jurisdiction which is what <br /> the regulations that the county enforces. I don't recall if it is or not. <br /> The Certified inspector has classified the tank as a Category 2 tank,which has more stringent testing requirements than <br /> the category 1 tanks (your gas and diesel tanks) <br /> As pointed out in the report there are two testing options for the tank. <br /> One would be testing frequency of 10 year Formal External Inspection by Certified Inspector and a 20 year internal <br /> Formal Internal Inspection by Certified Inspector <br /> The other would be a 5 year Formal External Inspection by Certified Inspector and a 10 year Leak test by owner or <br /> owners designee. <br /> All the testing would need to comply with STI SP-001 standards. <br /> The report states that the inspection intervals begin from the current inspection date which would seem to be 2019 <br /> from the inspection reports. <br /> The standard however states the following <br /> The owner shall use the AST's type,capacity, installation characteristics, and previous inspection history,if any,to <br /> develop a schedule of applicable types of inspections for each AST,per Table 5.5.The interval for the initial inspection <br /> shall begin from the AST's initial service date.If the initial service date is not known, the owner shall he responsible for <br /> establishing and documenting the initial service date(for example, from nameplates, as-built drawings,manufacturer cut- <br /> sheets,due diligence reports,fire marshal inspection records, state operating permits,building code permits,etc.). <br /> If the tank is under state APSA jurisdiction (contains petroleum)the internal testing or leak test will need to be verified <br /> by the next APSA inspection,which is three years from the original inspection by the county. Based on the estimated age <br /> of the tank,the initial service date is over twenty years and internal or leak tests have not been performed per STI SP- <br /> 001 standards. <br /> Let me know if there are any questions. <br /> FREE classes presented by NES Inc. are available to all San Joaquin County Hazardous Waste, Underground Storage Tank, <br /> and Aboveground Petroleum Storage Facility Business Owners and Operators.
