Duncan Compliance: Dba, R&D Compliance Testing <br /> Secondary Containment/SB989 (707)621-0378 <br /> Line/Leak Detectors <br /> Tank Monitor Certification <br /> California UST Service Technician#5246802-UT <br /> California UST Designated Operator#5246802-UT <br /> CSLB C61/D40 License#1036490 <br /> Secondary Containment Test Procedure Used To Determine Test Results <br /> Tank Secondary Containment—The Service Technician will test and certify using <br /> methods developed and recommended by the Tank Manufacture, Industry Standard or <br /> Professional Engineer. Test procedure recommended and used is a vacuum slowly <br /> applied to establish a stable vacuum of 6"to 10" inches Hg. for one hour using a <br /> Standard Industry Vacuum Gauge with a range of-0"to -30"measured in Hg./inches of <br /> mercury. The test is completed at the end of one hour/Tanks with a Volume of 20,000 <br /> Gallons or less, and 2 hours for Tanks that exceed a Volume of 20,000 Gallons, if the <br /> vacuum reading does not decrease below the established vacuum or the Threshold <br /> Criteria recommended by the Tank Manufacture, Industry Standard, or Professional <br /> Engineer. <br /> Product Piping Containment/Vent Piping Containment/Vapor Recovery Piping <br /> Containment—The Service Technician will test and certify using methods developed <br /> and recommended by the Piping Manufacture, Bravo System UDC Manufacture, Industry <br /> Standard or Professional Engineer. Test procedure recommended and used is,Nitrogen <br /> Gas pressure, slowly applied to establish a stable pressure of 5 psi for one hour or 3 Psi <br /> for 1 hour using a Standard Industry Pressure Gauge with a range of 0 to 15 measured in <br /> Psi/Pounds per square inch. If the Product Piping is Fiberglass and the UDC's are a <br /> Bravo System Manufacture, constructed of Coated Steel, with an O Ring Seal at <br /> Primary/Secondary Product Piping Interface at end of Product Piping Run at UDC's then, <br /> Bravo System Manufacture recommends a maximum applied test pressure of 3 Psi. The <br /> test is completed at the end of one hour if the pressure reading does not decrease below <br /> the established pressure or the Threshold Criteria recommended by the Piping <br /> Manufacture, Bravo System UDC Manufacture, Industry Standard or Professional <br /> Engineer. <br /> Turbine/Product Piping Sump/Fill Riser Sump/Remote Fill Sump/Transition/Vent <br /> Sump/Spill Container/Misc. Sump connected to UST System —The Service <br /> Technician will test and certify using methods developed and recommended by the Sump <br /> Manufacture, Industry Standard or Professional Engineer. The test procedure <br /> recommended and used is Hydrostatic with a level change indicator that has been <br /> developed to indicate a standard leak rate of 1/4 inch in 24 hours within 30 minutes, and <br /> has been examined and reviewed by a third party Professional Engineer. The Service <br /> Technician will perform all Hydrostatic Testing using the Caldwell Systems Level <br />
