ti A. G. SPANOS CONSTRUCTION, INC. 1341 W.ROBINHOO❑ORIVE • STOCKTON,CALIFORNIA 95207 TELEPHONE{2091478-7954 March 31., 1993 Mr. Mike Purcel AP9 0 1 1593 Chevron U. S .A. Products Company ENVIRONMENT P.O. Box 5004 P R� III �Avd� S HEALTH San Ramon, CA 94583-0804 SI:"v Re: Chevron Station No. 9-6465 5608 North Pershing Avenue Stockton, California Dear Mr. Purcel : we recently learned that, in addition to contaminated soil adjacent to the waste oil disposal. tank and in the bottom of the major tank pit of the above referenced property, there have been product releases from the distribution pipes in the vicinity of monitoring wells one ( 1) and two (2 ) . This condition, apparently of many years duration, is that for which the monitoring wells were required. We understand that Chevron intends to remove the contaminated soil from the tank areas and replace it with clean fill . We also understand that Chevron has not yet decided on a remediation for the contamination resulting from the product spill . Apparently one alternative would be to excavate, stockpile and aerate the soil until the contamination is reduced to acceptable levels . The soil would then be returned to the excavation. That is not acceptable to the owners . The owners have an alternative use for the property which requires that the premises be returned to them as soon as possible. Given that Chevron has known about the product release for years and that its lease allows only a reasonable time to accomplish the removal of the improvements and remediation of the site, the owners insist that Chevron remediate by the most expedient means, even if that is not the cheapest. Additionally, we require that all of the monitoring wells be closed and abandoned in accordance with County requirements as part of the closure. Should the alternative use be lost because Chevron did not diligently pursue its obligation to deliver the site in a timely manner, we would look to Chevron to compensate for the loss .
