For the removal plan <br /> deficiencies you will find, a new "Application for permit for <br /> underground storage tank closure" , a new Monitoring and Response <br /> Plan for San Joaquin County and new decontamination verbiage <br /> pertaining to the removal of tanks. . . , enclosed. <br /> As per the installation deficiencies, a new site plan with <br /> existing utilities is enclosed on a 8 1/2" by 11" . You will also <br /> find a new response plan which address the proposed method and <br /> equipment to be used for removing hazardous materials including <br /> excess contaminated water from a holding facility. <br /> Our monitoring plan states, that in the event of a leak that the <br /> product will be contained in the annular space, true. Once the <br /> primary tank develops a holy:, the liquid in the annular space and <br /> the primary tank will seek a common level , thus causing the water <br /> level to drop while raising the product level . The only way that <br /> excess fluid could spill into other areas would be if additional <br /> fluid was being added into the system. I have enclosed cut <br /> sheets from Owens-Corning depicting various situation regarding <br /> tank leaks. <br /> The tank level gauge used on this project will be a Veeder Root <br /> TLS 250. <br /> Yes, we will be installing a OPW 61 SO at this site. <br /> bRANCHESs LARKSPUR,CA(415)461-0990 PlUTALUMA,CA(707)765-10410 <br />
