(Stratus). In <br /> the report, Stratus requested that the site be evaluated by EHD for closure <br /> consideration and that preparation of California Regional Water Quality Control <br /> Board (CRWQCB) Appendix B documentation be directed. The request was also <br /> conveyed verbally by Mr. Jay Johnson by telephone 30 May 2002 and 21 June <br /> 2002. To consider the request EHD also reviewed portions of Additional Soil and <br /> Groundwater Investigation Report, dated 27 October 2000 and previous boring <br /> logs and cross sections. A brief summary of recent site activities and findings is <br /> as follows: <br /> A 1,000-gallon underground storage tank (UST) was removed from the <br /> site in July 1988; soil impacted by hydrocarbons was encountered during <br /> the UST removal. <br /> In February 1997, three soil borings were advanced on the site, two of <br /> which were converted to ground water monitoring wells, MW-1, screened <br /> from 16 to 25 feet below surface grade (bsg) and MW-2, screened 15 to <br /> 39 feet bsg. Impacted soil was encountered in the vadose zone underlying <br /> the boring advanced in the former tank pit, impacted soil was encountered <br /> in the saturated zone in all three borings. Ground water in the two wells <br /> was impacted by petroleum hydrocarbons as gasoline (TPH-g) at <br /> concentrations as high as 18,000 parts per billion (ppb) TPH-g and 4,400 <br /> ppb benzene. <br /> • Five other impacted UST sites are in the immediate vicinity of the subject <br /> site and a commingled plume of impacted ground water, incompletely <br /> assessed, reportedly underlies portions of the area. <br />
