Donald N. Hoffman 9 11828 Dublin Blvd. Dublin, CA 94568 (510) 829-8491 �2 April 3, 1995 Diane Hinson and Steve Sasson San Joaquin County Health Services and Environmental Health Division 445 North San Joaquin Street Stockton, California 95205 Subject" My property at 835 Clover Rd. , Tracy, CA Site code 2068 (APN 214-180-42,43) Ms. Hinson and Mr. Sasson, I have just reviewed the Terrasearch amended work plans and request for closure on the subject "contamination" problem. Within the last week I also talked to Ben Curran, broker for my purchase of the property, and the son of Ralph Hayes (deceased) , former owner of the property. According to his son, Ralph Hayes quit his effort for closure of the site about 1990, when he tried to get closure, and was told by your department that he would have to do another round of monitoring and that there was "a problem" because the project file had been "misfiled". A month later the file was still lost, and has never been located. This explains why your records show only one scrap of a field inspection report. To quantify the amount of contaminated soil, we have had to completely redo the original work including excavation of probably 250 C.Y. of original sand backfill as well as maybe 70 C.Y. of surrounding native clay after spending considerable time and money just locating the original tank excavation by exploritory drilling. This information was undoubtedly in the lost report of the earlier work. Now, five years and $20,000.00 later, I am asking for closure. There is apparently less than a gallon of diesel oil in the stockpile and in the small amount of material around the bottom perimeter of the hole. It will cost a couple of thousand dollars to bring that material to the surface and into the stockpile, and more to backfill the excavation.
