INTRODUCTION ' This report provides a summary of Bechtel National, Inc. 's (BNI) ' Phase 1 site contamination investigation at the Stockton Division facility of the American Forest Products Company (AFPC) . It ' describes Phase 1 field sampling and chemical analysis methods and their results, and provides conclusions regarding the extent of site contamination and recommendations for future action. Background ' AFPC operates a lumber remanufacturing facility at Stockton, ' California. The facility purchases lumber from other mills and produces various finished products, among them furniture kits, cut ' stock (dimensioned lumber) , shooks (agricultural boxes) with covers, and mouldings. ' The California Department of Health Services (DOHS) conducted an inspection of the facility on February 23 and 29, 1984. A DOHS ' inspection report citing violations of environmental laws and regulations and possible site contamination was sent to AFPC on ' March 6, 1984. In April 1985, AFPC submitted a Preliminary Compliance Plan (prepared by BNI) to DOHS which addressed the violations cited in the inspection report. ' A two-phased site contamination investigation was included in the ' Preliminary Compliance Plan. The objective of Phase 1 was to provide qualitative information for identifying contaminated areas ' of the site. Phase 1 was to also provide limited information on the lateral and vertical extent of any existing contamination. DOHS ' approved the Phase 1 site contamination investigation program. If site contamination was found to exist, a Phase 2 investigation would then be initiated. Phase 2 would provide additional information on ' the lateral and vertical extent of the contamination and obtain data necessary for developing design criteria to implement a successful ' remedial action program. - 1 - 2611F
