INWqw low 6.0 Summary The French Camp site is located at 4599 Manthey Road, French Camp California, approximately 3 miles south of Stockton. The 6-acre site was used as a dump site for off- specification asbestos-containing piping and other asbestos waste between the early 1970s and 1985. Approximately 13,000 cubic yards of debris is believed to have been disposed of at the site, some abandoned in piles on the surface. The site is bordered by agricultural land on three sides, with Interstate 5 located approximately 400 feet to the east. The site is unfenced, and there are two residences within 500 feet. The San Joaquin County Health Department referred the site to the California Environmental Protection Agency Department of Toxic Substances Control (Cal EPA DTSC) in 1985; Cal EPA DTSC subsequently referred the site to the U.S. EPA Emergency Response Section in June 1985. Cal EPA DTSC conducted sampling at the site in 1986, confirming the presence of chrysotile asbestos in friable piles of surface debris, and the existence of a health threat to surrounding workers and residents. Cal EPA DTSC issued an order to the Responsible Party (RP) requiring the mitigation of the immediate threat represented by the friable asbestos-containing materials. The RP did not respond to the state order. As a result, Cal EPA DTSC requested assistance from the U.S. EPA Emergency Response Section in March 1988. The EPA Technical Assistance Team conducted a Preliminary Assessment of the site on April 6, 1988, collecting samples which confirmed the widespread presence of chrysotile asbestos on-site. Cal EPA DTSC contracted to apply a soil sealant to the site as an interim measure, while EPA negotiated with the RP, Malcolm Equina. In May 1989, a CERCLA 106 order was issued to the new title holder of the property, Lyon Communities, requiring mitigation of the site. The permanent capping of the site was finally completed in 1991, and a deed restriction was placed upon the property to prevent any construction work'that would impact the cap's integrity. The following are the HRS factors pertinent to the French Camp site: ■ The asbestos-containing waste is capped and is not available for dispersal by wind. • The chrysotile asbestos in the pipe debris is not leachable and therefore cannot migrate via groundwater.
