Phase I Environmental Site Assessment Neighborhood E Page 13 7.0 ADDITIONAL SERVICES No additional services were requested. 8.0 FINDINGS The Site is agricultural land, currently planted with corn and alfalfa with some fallow portions. The Site reconnaissance revealed the following suspect environmental conditions: • One 500-gallon capacity aboveground storage tank(AST)with minor associated soil staining. • Two bermed structures, one containing a tailwater pond with a small amount of water. No suspect environmental conditions were identified on any nearby properties during the Site reconnaissance. The review of ASTM-specified environmental records identified two locations within the specified search radii. Trimark Communities (18621 Mountain House Parkway), located about 1,600 feet to the northeast of the Site, was identified by the Hazardous Waste Information System (HAZNET) database. M & T Souza, located about 3,800 feet to the south of the Site, was identified by the Resource Conservation Recovery Act Information System-Small Quantity Generator (RCRIS-SQG) and Facility Index System (FINDS) databases. Review of San Joaquin County Public Health Services/Environmental Health Division (PHS-EHD) and San Joaquin County Office of Emergency Services (OES) records produced no further information regarding the locations. Additionally, there are no records on file with PHS-EHD or OES for the Site or its adjoining properties. Pesticide Use Reports provided by the San Joaquin County Agricultural Commissioner's Office revealed that pesticides have been used on the Site for the last five years. An interview with the site manager also indicated the use of pesticides for agricultural purposes at the Site. 9.0 OPINION No historical recognized environmental conditions were identified for the Site. Condor found one condition at the Site that is considered a recognized environmental condition pursuant to the ASTM Standard: • During the Site reconnaissance, one 500-gallon AST was identified on the Site with some minor soil staining beneath it. Condor identified one de minimis condition at the Site: • During the Site records review and interviews, the past use of agricultural chemicals on the Site was identified. The AST constitutes a recognized environmental condition pursuant to the ASTM Standard. Leakage from the AST containing petroleum products could possibly introduce petroleum hydrocarbon components, including benzene, toluene, ethyl benzene, total xylenes (BTEX), or methyl tertiary butyl ether (MTBE) into the soil. Containment by a relatively small excavation in the area of the AST would likely remove the potentially contaminated soil and could eliminate the recognized environmental condition. Sampling should be performed at the time of excavation to confirm removal of all contaminated material. Proper disposal of the soil should be arranged. The historical application of pesticides to agricultural land at the Site is considered to be a de minimis l condition by Condor. Much of the Central Valley was, at one time, used for agricultural use. and hence 1 the presence of pesticide residues is anticipated in the soils. This de minimis condition designation for lkmtilo� A CONDOR
