(Stratus) has prepared this letter, on behalf of USA Gasoline <br /> Corporation (USA), to request an authority to construct (ATC) and permit to operate a <br /> trailer mounted Solleco 100 cubic feet per minute (cfm) soil vapor extraction system <br /> (SVE) at USA Service Station No. 65, located at 2500 West Lodi Avenue, Lodi, <br /> California (Figure 1). A completed application, supplemental information for soil and <br /> groundwater remediation, and a check in the amount of $60.00 are presented in <br /> Appendix A. <br /> Stratus proposes to install and operate a Solleco 100 cfm SVE system consisting of a <br /> 5-horsepower (hp) Roots positive displacement blower and an electric catalytic oxidizer <br /> rated at 100 cfm. Petroleum hydrocarbon laden soil vapors will be extracted using the <br /> 5-hp blower, and abated in the catalytic oxidizer prior to discharge to the atmosphere. <br /> The SVE system will be operated 24 hours a day, 7 days a week, and 52 weeks a year, <br /> beginning August 30, 2004. <br /> Prior to this application, an SVE system, consisting of a 2.3 hp Fuji regenerative blower <br /> rated at 150 cfm and two 2,000-pound vapor phase virgin coconut shell carbon units in <br /> series, was operated intermittently between August 2003 and March 2004, under Permit <br /> No. N-4887-1-0. Due to poor performance/low destruction efficiency of the carbon <br /> adsorption system resulting in high operation and maintenance costs (frequent carbon <br /> change-outs), this SVE system was shut down on March 12, 2004, pending re-evaluation <br /> of the design of the SVE system. In addition, a 150 cfm Stealth Bobcat catalytic oxidizer <br /> was also operated at the site between August 15, 2000 and August 15, 2002, under permit <br /> N-903-2-0. The Stealth Bobcat catalytic oxidizer was replaced with the carbon <br /> adsorption system due to low influent concentrations. The operational and analytical <br /> summaries for the previously operated SVE systems are presented in Appendix B. <br /> PAUSA Gasoline%00651Correspondence\USA 65 ATC For New UnitNUSA 65 ATC for new Unit.doc <br />
