Inc. <br /> 2410 Camino Ramon <br /> San Ramon, California 94503 <br /> RE: Vapor Extraction and Treatment Systam <br /> Fortner Chevron SS 9-018 <br /> 45 East Harding Way <br /> Stockton, California <br /> Dear Ms. Marinaro: <br /> Please find encloaed EA's proposal for the installation and oper- <br /> ation of a Vapor Extraction and Treatment System (VETS) at the <br /> site of former Chevron Service Station (SS) 9-1918, located at 45 <br /> East Harding Way In Stockton, California. The proposed treatment <br /> system employs the HasGtech Multimode combustor similar to the <br /> one you vievoe. In Oakdale. The VETS consiats of a vacuum pump <br /> unit to provide the auction for soil vapor removal, a flame <br /> incinerator to burn off the bulk of the hydrocarbon contaminants, <br /> and a catalytic reactor to removes the remaining contaminants for <br /> fl.%al hydrocarbon-free discharge. Once purchased and permitted <br /> appropriately, thin system Is easily m- yed to additional sites <br /> for continued operation. <br /> The work plan and budget proposed herein covers purchasing, <br /> installing, parmittinj, testing, sampling, and operating the unit <br /> for six months. Operation beyond the 6-month period will depend <br /> on the level of cleanup obtained at the site, and is not covered <br /> under the proposed costs. <br /> EA is prepared to begin the permitting and acquisition processes <br /> within one week of written authorization to proceed. Delivery of <br /> the Hasstech systam to the site 16 est1mated to take 4 to 7 weeks <br /> from the date of order; permitting Is also expected to require <br /> the same 4 to 7 weeks. System lnstallation will require two <br /> --weeks,.-and-fita-r tup-ton tina.-and--sys tem-adjuaMent-vi I I- require-an <br /> additional week. <br /> BALTIMOOE C CHICAGO 0 CtNCINNATI 0 LINCOLN 0 NEW YORK 0 SANFRANCISCO <br /> 14 <br /> 0=1 <br />
