Project No. 076-97005 <br /> r Page No.2 <br /> 3.0 PROCEDURES AND FINDINGS <br /> The UST removal and soil sampling activities were conducted under the direction of Mr. Eric <br /> r <br /> Trevena of the San Joaquin County Public Health Services, Environmental Health Division (SJCEHD). <br /> The removal contractor was Jim Thorpe Oil, Inc. Krazan & Associates (Krazan) was present to observe <br /> field activities and collect soil samples. <br /> Prior to Krazan's arrival at the site, the overlying soil had been removed and the USTs exposed. <br /> The USTs were not triple-rinsed prior to or during Krazan's observation. According to the "Application <br /> for Permit to Close USTs Storing Hazardous Materials", the USTs will be transported off-site to Ameri- <br /> r <br /> Clean,Inc., in Silver Springs,Nevada. Upon removal,the USTs were observed to be of single-wall, steel <br /> construction and were noted to be in relatively fair condition with a moderate amount of surficial rusting. <br /> The tank sizes, product contents, approximate capacity, and SJCEHD UST identification number is <br /> provided in Table I. <br /> r <br /> TABLE I <br /> UST Data <br /> Hutchins Street Square <br /> 125 South Hutchins Street <br /> Lodi, California <br /> April 10, 1998 Tank Removal <br /> UST No. Product Volume Dimensions(feet) <br /> A fuel oil 6,000 gallons 7 x 20 <br /> B fuel oil 3,000 gallons 4 x 10 <br /> The soils present in the excavation for the USTs appeared to be fill material comprised of <br /> reddish-brown, silty sand. Groundwater was not encountered during the excavation and tank removal <br /> procedures. <br /> Petroleum hydrocarbon odors were not noted within soils removed from the UST excavation. <br /> Soil discoloration was not noted in soils removed from beneath the UST excavation, with the exception <br /> of a relatively small amount of fuel oil which spilled during the removal of the USTs. The spilled fuel <br /> 6' oil and soil surrounding the spill was overexcavated and stockpiled for transport to Forward Landfill in <br /> San Joaquin County,California. <br /> As directed by Mr. Trevena, Krazan's representative collected four soil samples from beneath <br /> the USTs on April 10, 1998. Relatively undisturbed samples from the excavations were obtained from a — <br /> ►� backhoe bucket using brass sleeves in accordance with SJCEHD guidelines. Soil samples were collected <br /> from a depth of approximately three to four feet beneath the bottom of the USTs.
