PRELIMINARY SITE ASSESSMENT WORK PLAN <br /> March 1996 <br /> Alberg Trucking <br /> 13430 Lower Sacramento Road <br /> Lodi, California <br /> 1.0. INTRODUCTION <br /> In accordance with the request of Mr. Fred Alberg,A&wnced GeoEnvironmental, .Inc. (AGE) has <br /> prepared this Site Assessment Work Plan for the advancement of two angled soil borings in the <br /> vicinity of the former underground storage tank (UST) area at 13430 Lower Sacramento Road in <br /> Lodi, California(the site). The location of the site is illustrated on Figure I -Location jalap. A plan <br /> of the site is illustrated on Figure 2 - Site Plan. <br /> The investigation is performed in accordance with San Joaquin County Public Health Services - <br /> Environmental Health Division (PHS-EHD) and Central Valley Regional Water Quality Control <br /> Board (CVRWQCB) guidelines for the investigation of underground storage (UST) sites. <br /> 2.0. BACKGROUND <br /> 2.1. SITE DESCRIPTION <br /> The site is located in a rural residential area of San Joaquin County, south of Lodi (Figure 1) and is <br /> presently occupied by a bar/restaurant. Fred Alberg Trucking is located on the property immediately <br /> south of the site. <br /> 2.2. UNDERGROUND STORAGE TANK REMOVAL <br /> It is our understanding that two 500-gallon and one 250-gallon underground storage tanks(UST s: <br /> Tank 91, Tank 42 and Tank 93) were removed from three separate excavations on the property in <br /> January 1988. One additional 250-gallon UST was slurry filled with concrete under the inspection <br /> of the PHS-EHD and abandoned in place. The 250-gallon tank is located partially under the building <br /> at the site. <br /> Soil samples were collected from beneath each removed UST and analyzed for total petroleum <br /> hydrocarbons quantified as gasoline and diesel (TPH-g and TPH-d), volatile aromatics (benzene, <br /> toluene, ethyl benzene and xylenes: BTE&X) ethylene dibromide (EDB) and total lead. <br /> Analytical results of soil samples indicated that TPH-g and BTE&X were present in soil samples <br /> beneath Tank 93 (250-gallon), located near the southern portion of the site. Therefore, the PHS- <br /> EHD required further investigation at the site to determine the lateral and vertical extent of <br /> hydrocarbon impacted soil. <br />
