MAIL ft (8). The Johns Manville Pipe Company was located at Sperry Road and Airport Way, in Stockton, approximately 1.5 miles north of the Equinoa property. The company operated from 1957 until 1982, when Johns Manville Pipe Division was sold to J-M Manufacturing, Inc., an unrelated company. In addition to waste disposal at the Equinoa site,Johns Manville operated a 40-acre landfill on-site at its Stockton facility(8). The Equinoa property was reported to the San Joaquin County Department of Health (CoDOH) in April 1985 by Anderson Geotechnical Consultants, which identified surface and subsurface deposits of asbestos waste (9). Subsequent PAs conducted by Cal EPA DTSC and EPA TAT identified asbestos waste piles on the surface and below grade, on the Equina property (3,4). Cal EPA DISC applied a polymer sealant to the site in 1988 to prevent further air dispersal of the waste, after the Responsible Party(RP), Equinoa, failed to respond to a county order to fence and cap the site in 1985 (4). On November 15, 1988, Lyon Communities assumed title of the contaminated Equina property; Lyon subsequently assumed title of the Thomas property on January 20, 1989, since it was apparent that the Equinoa property could not be satisfactorily remediated with the residential parcel isolated in its center (7). The French Camp site was thus redefined to include the 1.16-acre Thomas parcel; earlier references to the site consider only the 4.96-acre Equinoa property (3, 4). Lyon Communities is the current owner of the French Camp site. Lyon Communities was issued CERCLA Section 106 order 89-09 in May 1989, requiring it to develop a remediation workplan within 21 days (2). Subsequent to this, the Thomas residence was demolished, the site was cleared of debris, and an interim 6-inch soil cap was installed over the site in 1990. A final 3-foot thick cap of clean fill, together with a wire mesh to prevent rabbits from entering the site, was installed on-site in 1991 (7, 18, 19, 20). 2.4 Regulatory Involvement The San Joaquin County Environmental Health Department (CoDOH) was notified of the Equinoa site in May 1985 by Anderson Geotechnical, a private geotechnical company (9). Cal EPA DISC was subsequently notified of the potential health threat presented by the site (11); it in turn notified the U.S. EPA Field Operations Branch on June 13, 1985 (10). In August 1985, CoDOH issued a California Health and Safety Code violation to the RP (Malcolm Equinoa) ordering him to fence, post, and cap the waste material at the site (4). The RP was unresponsive to this order (4). URS Consultants, Inc. Page 7
