State Water Resources Carol Board Division of Clean Water Programs UST Cleanup Fund Program January 14, 1992 Page 2 The property, an automotive sales and repair facility, was purchased with three (3) underground storage tanks formerly utilized to store gasolines, but not in service at the time of the acquisition. , The buyers (now owners) had knowledge of the tanks, but no knowledge of any contamination. The tanks, under a mandate for removal by the City of Tracy, were destined for removal due to non-use in the previous five (5) years. The present owners, in fact, then removed the three (3) dormant tanks (under the then-governing regulations) under jurisdiction of the Tracy Fire Department Permit No. 00920, with final inspection sign-off(without incident)on November 5, 1981 (copy attached). The removals were accomplished without incident by a licensed contractor (invoice copy attached). When considering a sale of the property in early 1987, the possibility of UST contaminated soil precipitated the engagement of a consulting geotechnical firm to investigate, test, and report on the existing site conditions with respect to UST contaminants. Test borings were taken and three (3) monitoring wells were installed. Low level hydrocarbon contaminants were found in one small area of the property. Reports of the findings were transmitted to the appropriate county and state regulatory agencies. Bi-annual site monitoring and testing of the three wells continues, with appropriate reports to the regulatory agencies (summary report attached). Accumulated costs to date for engineering, well construction, and well monitoring are approximately $30,000. Current estimated costs to remediate(remove,remediate,refill) are estimated to be$50,000 to$150,000,depending upon in-situ conditions as found when excavating. All required data referenced and required in the UST application forms is available.
