The Caltrans' interchange project at the <br /> junction of Highways 4 and 99, requires approximately one third of the east portion of this site for <br /> construction. In September 1989, Caltrans became aware of problems with this site and has <br /> worked with the Department of Health Services, the San Joaquin County District Attorney's Office, <br /> and the San Joaquin County Environmental Health Division to get resolution to this problem and <br /> keep our project on schedule. <br /> The following is a brief history of this site as I know it: <br /> In February 1988 the Department of Health Services investigated Roy's Auto Wrecking at <br /> the request of the California Highway Patrol. During the investigation it was observed that <br /> there was standing oil and antifreeze on the site. DHS obtained surface samples at <br /> locations that appeared to be the worst areas. The samples had high concentrations of <br /> lead and the fluids that were tested had pH readings as low as 3.6. No subsurface samples <br /> were taken. <br /> The Report of Violation was sent to Mr. Knoll on July 19, 1988. Mr. Knoll did not <br /> .vlu'itc,:rily CO�i�Ni'y' Yti'iiii iil8 iiuci aiiu vi IS l:UriSlliercU iris a low priority project and <br /> followup on the cleanup order was not done. After our meeting with DHS, the case was <br /> referred to the DA's Office in October 1989 and a suit was filed. <br /> During the next several months Caltrans had meetings with the DA and Mr. Knoll to <br /> determine the progress of the site investigation and cleanup. In August 1990 a stipulation <br /> was prepared by the DA and signed by Mr. Knoll which provided 30 days for Mr. Knoll to <br /> supply the name of a consultant and 90 days to prepare and submit a work plan for the <br /> investigation of the site. <br /> After discussions with the DA in September 1990, it was apparent that Mr. Knoll was not <br /> going to comply with the stipulation. Caltrans met with Mr. Knoll on October 1, 1990 and <br /> offered to do the investigation on the portion of the property required for the freeway <br /> construction. The Caltrans' consultant prepared a work plan, which was reviewed by the <br /> Environmental Health Division, and the investigation was scheduled for December 1990. <br />
