EHD has verified on October 16, 2013 that the <br />87 -octane leak detector had to be removed as a part of the repair process. The permit has <br />been approved with the following conditions: <br />Contact the local fire department and the San Joaquin Valley Air Pollution Control <br />District for any applicable permits and requirements. <br />2. Any changes in information and scope of work must be submitted to EHD for approval <br />prior to commencing work. All new addenda supersede the previous ones. <br />3. Contact Jeffrey Wong at (209) 468-0335 to arrange the following inspection <br />appointments. <br />a. Primary piping soap test: One hour pneumatic pressure test at 110% of operating <br />pressure, or 40 psi, whichever is greater. <br />b. Secondary piping soap test: One hour pressure test per manufacturer's guidelines. If <br />there are no manufacturer's guidelines, test shall be performed using an applicable <br />method specified in an industry code or engineering standard. <br />c. Leak detector test: Leak detector must be tested during normal operating condition <br />after concrete has been poured and set, to confirm that the device can detect a leak <br />of 3 gallons per hour at 10 psi. <br />Please be aware that the facility cannot operate the UST system prior to the EHD <br />inspection and approval. <br />4. Since piping has been damaged, a soil sample is required to evaluate if an unauthorized <br />release has occurred. Have the laboratory collect a native soil sample beneath the <br />piping at a depth not to exceed 2 to 4 feet, and analyze for unleaded gas constituents: <br />TPH-G, BTX&E, and all 5 oxygenates including 1,2 -DCA and EDB using EPA Method <br />8260 by a 3rd Party laboratory. Results of the analyses must be submitted to EHD <br />directly from the laboratory. <br />
