The on-site and off-site groundwater wells were destroyed in July 2012. MW-10, located in the northwest section of the subject property, was destroyed y pressure-grouting to a depth of 3 feet bgs. The case was closed November 9, 2012, with a o Further Action Letter issued by the San Joaquin County Environmental Health Department. ntaminated soil at 21 feet bgs was left in-place, as it was determined that the contaminant pit me is shrinking. This is considered a Historic REC (HREC). No active leak has been detected ii the new tanks. However, if these USTs were to leak, the subject property would likely be im acted. This constitutes an REC. 845 Pine StreetIT ns Lodi Mai ten ti Ad'acent South/Down-Gradient) The two 1,000-gallon USTs at the property were removed in 1989. Petroleum hydrocarbons, VOCs and fuel oxygenate compounds were not detected in the soil or groundwater samples taken February 2002 at concentrations in excess of the analytical method reporting limits. A No Further Action Letter, dated June 12, 2002, from the Regional Water Quality Control Board was identified. No impact to the subject property is anticipated from this property. 900 and 900 1/2 Victor, Teresi Trucking fAdiacent East-Northeast/Uo-Gradient) Three USTs were removed from this property on December 1, 1995. Contamination at the site was located at 35 feet bgs, after the excavation was completed. Groundwater at the site has not has not risen above 50 feet since during the investigation, therefore, the case was closed April 13, 2001, even though contaminated soil was still located at this property. No impact to the subject property is anticipated from this property. 6.4 Interviews with Others No other interviews were conducted 7.0 EVALUATION 7.1 Findings • The subject property is located on the RGA LUST, CA FID UST, SWEEPS UST, HIST UST, and UST databases. • Three underground storage tanks were removed from the property in 1986, and replaced with three new tanks. Leaks were discovered from the old tanks and sail was excavated to 31 feet bgs. A No Further Action Letter was issued by the Environmental Health Department on April 7, 1998 and by the California Regional Water Quality Control Board July 8, 1997. • The three replacement underground storagefi�nks were removed in 2001. Soil contained elevated levels of motor oil. Tank closur@ was issued by the County on March 19, 2002. The Tank Closure letter did not alleviate owner responsibility to cleanup contamination associated with the removed USTs. • Soil approximately 30 feet bgs in the vicinity of the former gasoline USTs remains contaminated. • Pavement staining is evident on the property.
