KLEINF-EL ER Bright People.Fight Solutiom to initiating the field activities (copy of permit in Attachment C). Underground Services Alert and the local fire department were contacted prior to field activities. FIELD ACTIVITIES The original UST location on the east side of French Camp Road (Plate 2) was re- excavated by Kleinfelder and observed on September 26, 2013. Kleinfelder personnel collected soil samples at and beneath the estimated UST elevation and from the excavated and stockpiled soil. The soil samples were analyzed per the directives of SJCEHD and for soil profiling purposes, assuming potential disposal. Personnel present during the field activities included Mesdames Stacy Rivera and Thuy Tran from SJCEHD, Mr. Josiah Hall of PB, Mr. Paul McConahey from the Stockton Fire Department, and Messrs. Vincent Wang and Doug Heard from Kleinfelder. UST Preparation, Transportation and Disposal RAH Environmental from Loomis, California (RAH) arrived at the Site on September 26, 2013 with a backhoe to excavate the former UST area and to load the UST onto a transportation truck provided by C&H Veteran Enterprises, Inc. (C&H). Prior to UST loading and transport RAH inserted approximately 20 pounds of dry ice into the UST and monitored gas levels within the UST using a Lower Explosive Limit meter to evaluate fire and explosion hazards. The gases monitored included methane, oxygen, hydrogen sulfide and carbon monoxide. RAH labeled the tank and wrapped it in plastic sheeting prior to transportation. C&H, a licensed hazardous waste transporter, transported the UST for disposal to Ecology Control Industries in Richmond, California. The "Uniform Hazardous Waste Manifest" is located in Attachment D. UST Excavation and Soil Sampling RAH began excavation in the area of the reported UST (see Photograph 1 and 2, Plate 3) on September 26, 2013. The final excavation was oblong with approximate dimensions of 12 x 10 x 9 feet deep (Photograph 4, Plate 4). The digging was noted to be relatively easy with soils noted to be predominantly silty sands with some clay. No unusual odors or soil discoloration was noted within the excavation, from soil excavated or exposed in the immediate proximity to the UST. No tank backfill material or water was observed in the excavation. Roadway fill material, consisting of aggregate base rock was noted in the upper foot of the soil profile. 125819.E01/ST013RO732 Page 3 of 10 December 11, 2013 Copyright 2013 Kleinfelder
