• Use of Test Fluid. <br /> FASTECH's testing fluid is comprised mostly of water with low concentrations (<2%) of surfactants and <br /> stabilizers. California Regulations allow for the transportation and reuse of water that is used as testing fluid. <br /> D.O.T. regulations mandate that the test fluid never contain more than 2% by volume of a hazardous material. <br /> Because of the extensive cleaning of the sumps prior to the introduction of the test fluid, the test fluid has never <br /> been determined to be hazardous. <br /> • Tank Annular Space. <br /> For tanks less than 20,000 gallons capacity, apply a vacuum of 10" mercury to annular space. After <br /> establishing a stable vacuum, maintain this vacuum for 60 minutes. At the end of the test period, if the vacuum <br /> reading has not changed from the established test vacuum, the test is complete and has achieved a "pass". <br /> For tanks greater than or equal to 20,000 gallons capacity, apply a vacuum of 10" mercury to annular space. <br /> After establishing a stable vacuum, maintain this vacuum for 120 minutes. At the end' of the test period, if the <br /> vacuum reading has not changed from the established test vacuum, the test is complete and has achieved a <br /> "`pass". <br /> If the tank does not maintain the test vacuum, the contractor may re-test the annular space. If, after the second <br /> test the tank does not achieve a "pass", the secondary containment must be considered not liquid tight. <br /> Repairs may be made by the tank manufacturer or authorized representative per the requirements of the local <br /> CUPA. <br /> • Product, Vent, and Stage 11 Vapor Piping Secondary Containment. <br /> An inert gas shall be used. The secondary containment shall be made airtight with either the rubber test boot <br /> or fiberglass test fitting installed at time of installation. If the test boot is missing or damaged, an approved <br /> replacement test boot or fiberglass test fitting may be installed. <br /> Pressurize secondary containment piping to 5 psig and allow to stabilize for 10 minutes. Maintain test pressure <br /> of 5 psig for 60 minutes. At the end of the test period, if the pressure reading has not changed from the <br /> established test pressure, the test is complete and has achieved a "pass". <br /> If the piping does not maintain the test pressure, the contractor may tighten clamps and fittings, if necessary, <br /> and re-test the piping. If, after the second test, the piping does not achieve a "pass", the secondary <br /> containment must be considered mot liquid tight. Repairs may be made by the piping manufacturer or <br /> authorized representative per the requirements of the local CUPA. <br /> • Containment Sumps and Under Dispenser Containment. <br /> The containment sump shall be free of dirt, debris and residual petroleum product. Place test fluid in the sump <br /> a minimum of 2-inches above the highest piping penetration. Electrical penetrations do not need to be included <br /> unless located below a product, vapor or vent piping penetration. Piping shall include primary/secondary <br /> product piping, vent piping, vapor recovery piping and siphon piping. <br /> After test fluid has stabilized for 30 minutes, the liquid level shall be measured using test equipment third party <br /> tested to below .0007-inches resolution. The test period shall consist of two 15-minute tests. At the end of <br /> each 15-minute test period, the test equipment must confirm a hydrostatic change in level no greater than .002- <br /> inches in order to achieve a "pass". <br /> If the containment sump does not pass the test, the contractor may re-inspect the sump, tighten <br /> penetrations/clamps and fitting, and re-test. If after the second test the containment sump does not achieve a <br /> "pass", the secondary containment must be considered not liquid tight. Repairs may be made using the sump <br /> manufacturer's procedures per abiding by the requirements of the local CUPA. <br /> Page 2 of 3 <br />
