2. SITE DESCRIPTION 2.1 Subject Site and Vicinity The subject site is located in east-central Stockton, at the intersection of Laurel and Watts Streets with Fremont Street. The previous tenant was Apache Plastics, who utilized the site to manufacture extruded plastic piping. The site is currently developed, with a warehouse (approximately 260 feet by 270 feet) occupying the western portion of the property (Figure 2). Asphalt paving covers the eastern portion of the property. Both the warehouse space and the adjoining paved area are currently utilized for recreational vehicle and boat storage. The property is bounded to the north by Fremont Street, to the east by a construction company's yard, to the south by railroad tracks, and to the west by a warehouse. In 1976, Apache Plastics installed a 1,000-gallon underground storage tank (UST) beneath the sidewalk along the northern property boundary. The UST was used to store gasoline. The UST and associated product piping were removed on August 11, 1992, A Sunland Gasoline station (Sunland) formerly operated at 2085 East Fremont Street, directly north of Apache Plastics across Fremont Street (Figure 2). The site was subsequently used for auto sales, and is currently occupied by a taxi cab company. Gasoline USTs were removed from this site in 1998, and hydrocarbon impact has been identified in both soil and groundwater beneath this site. The nature of impact at this site and its relation to the impact beneath the Apache Plastics site are discussed below. Some records suggest that one 2,000-gallon gasoline, one 2,000-gallon diesel, and one 5,000-gallon diesel USTs were installed at the Port Stockton Foods facility, immediately adjacent to the Apache Plastics site to the west (refer to Western Geologic Resources , Inc. potentiometric surface map dated September 29, 1989 in Appendix B). Information regarding the existence of these tanks or any environmental investigations that may have been performed at the Port Stockton Foods facility were not available for inclusion in this SCM. 2.2 Topography and Surface Conditions Topography in the vicinity of the site is generally flat, at an elevation of approximately 18 feet above mean sea level. The entire site is covered either by the warehouse building or asphalt paving. p_\Apache Plastics\ReportslApache SCM.doc Page 2 Stratus
