Woodward-Clyde <br /> 1.0 <br /> INTRODUCTION <br /> V <br /> The Federal Emergency Management Agency (FEMA) has undertaken a program to bring <br /> federal government-owned underground storage tanks (USTs) located at Emergency Alert <br /> System (EAS) stations into compliance with federal and state regulations. This may involve <br /> removal, replacement, abandonment, and/or upgrade of the tanks. The program involves <br /> approximately 650 protected EAS stations in the Broadcast Station Protection Program <br /> (BSPP) throughout the United States and its territories. BSPP stations contain federally <br /> funded equipment such as USTs and standby generators. The tanks are used to store diesel, <br /> gasoline, or fuel oil for operating transmitting equipment at least 14 days in the event of an <br /> V <br /> emergency. The radio station KJAX is one of the protected EAS stations within the BSPP <br /> program. <br /> FEMA retained Woodward-Clyde Federal Services (WCFS) to provide environmental <br /> consulting services for the removal and closure of one UST at the KJAX Radio Transmitter <br /> Station (site). An "Analytical Results Report" describing the removal of the FEMA owned <br /> UST at the KJAX site was prepared by WCFS in May, 1994 (WCFS, 1994). The May 1994 <br /> report described the existence of diesel contaminated soil at an approximate depth of 18 feet <br /> bgs below the north end (fill end) of the former UST. <br /> V <br /> This Preliminary Investigation and Evaluation Report (PIER) describes activities conducted <br /> in response to a letter to FEMA from San Joaquin County Environmental Health Division <br /> (SJCEHD) requesting further investigation of soil contamination which resulted from leakage <br /> from the former UST at the KJAX site. This PIER presents the results of the site <br /> characterization activities conducted at the KJAX site in Stockton, California. <br /> V <br /> Section 1.0 of this report presents physical setting, site background, regional and local <br /> hydrogeology, and project objective. Section 2.0 presents a summary of our field activities <br /> conducted May 25 through June 22, 1995 and Section 3.0 presents the findings of our field <br /> activities. Our conclusions and recommendations are presented in Section 4.0. Uncertainties <br /> V <br /> and limitations are discussed in Section 5.0. <br /> 8054TEMAWAXPIER.Rn/8-24-95 SAC 1-1 <br />
