' • • <br /> Remediation Well Installation Work Plan New West Flag City Facility <br /> August 7 2008 6437 W. Banner Street, Lodi, California <br /> ' 4.3 SOIL SAMPLING <br /> ' Soil samples will be collected at a minimum of every 5 vertical feet. Samples will be field <br /> screened for the presence of residual petroleum hydrocarbon vapor concentrations using a photo- <br /> ionization detector (PID). Soil samples collected will be classified by Closure Solutions field <br /> ' personnel according to the Unified Soil Classification System (USCS) and examined using <br /> visual and manual methods for parameters including odor, staining, color, grain size, and <br /> moisture content. Selected soil samples may be submitted under Chain-of-Custody protocols to <br /> a California ELAP certified analytical laboratory, as described in Section 4.4. Based on the <br /> ' locations of the proposed wells, no chemical analysis of the soil samples is planned. <br /> 4.4 SOIL SAMPLE HANDING AND ANALYSIS <br /> Each soil sample collected for possible chemical analysis will be covered at each end with <br /> ' Teflon"m sheeting, capped with plastic end caps, labeled, and placed in an ice-filled cooler for <br /> preservation. Any soil samples selected for chemical analysis will be submitted under chain-of- <br /> custody protocol to Kiff Analytical of Davis, California, a California State-certified analytical <br /> laboratory and will be analyzed for the following: methyl tertiary butyl ether (MTBE), ethyl <br /> tertiary butyl ether (ETBE), and tertiary butyl alcohol (TBA), tertiary amyl methyl ether <br /> ' (TAME), di-isopropyl ether(DIPE), ethanol, and methanol using EPA Method 8260B. <br /> 5.0 WASTE DISPOSAL <br /> Investigation derived waste (IDW) will be temporarily stored on-Site in 55-gallon, <br /> ' DOT-approved 17H drums, pending characterization and disposal. The IDW will be <br /> characterized in accordance with waste disposal or recycling facility acceptance requirements. <br /> ' Closure Solutions will coordinate the transport and disposal of the IDW at an approved facility. <br /> 6.0 GEOTRACKER <br /> ' In accordance with GeoTracker requirements, Closure Solutions will upload to GeoTracker all <br /> soil and groundwater analytical and gauging data, and copies of the boring logs and final report <br /> ' related to this investigation. <br /> ' Page 7 of 9 <br />
