1 KLE/NF .LIhl &i9hthMkN9�f bWXom Parcel 3 Kleinfelder conducted the Site Reconnaissance of Parcel 3 on October 31, 2016 with Mr. Lloyd Farmer, former owner and current lessee. Mr. Farmer was interviewed at that time and subsequently on November 1, 2016 by phone. Interview information and a copy of the interview documentation from Mr. Farmer are presented in Appendix C. Mr. Farmer indicated that a prior Phase I ESA, prepared by AGE, had been conducted in 2015 for Parcel 3. A copy of the report is presented in Appendix D, and a summary is provided in Section 5.5. Mr. Farmer purchased Parcel 3 in 1994 from Teichert Construction Company (Teichert) and sold it in 1995 to Doug Howard. Mr. Farmer commented that he believed the land was historically farmed and then purchased by Teichert in the 1970's. Onsite soil was thought to have been used by Teichert for the nearby 1-5 construction, although no fill was reportedly needed after Mr. Farmer's purchase. Mr. Farmer built the current building on the lot, leased the parcel from owner Doug Howard, and ran a trucking business for seven years between 1995 and 2002. The business hauled building material and had a fleet of up to approximately 65 trucks which were fueled, maintained and washed onsite. A former fueling island, canopy and 12,000 gallon diesel AST were installed to fuel the trucks near the current gate entrance off East Transportation Court from 1995 to 2004. The AST was single-wall metal construction within a concrete secondary containment, with a fuel dispenser on either side (north and south). An unknown amount of diesel fuel spilled in August 2005 during fueling of a truck from the north dispenser. JTO, of Lodi, California excavated approximately 30 cubic yards of fuel impacted soil. JTO then transported and disposed of the soil at an offsite disposal facility under manifest. According to the AGE 2015 Phase I ESA, GeoAnalytical Laboratories conducted confirmation soil sampling within the excavation and performed subsequent chemical analyses for various petroleum compounds. JTO backfilled the excavation with pea gravel. The diesel AST was demolished and disposed of offsite by Stockton Service Station Equipment in 2005. A summary of this event with few details were discussed in the 2015 Phase I ESA (see Appendix D). Mr. Farmer did not recall if the county health department was present during the clean-up process. 20172543.001A/ST016R49461 Page 45 of 54 November 2, 2016 ©2016 Kleinfelder v .kleinfelder.com
