r, File No. 20-3941-0LEO 1 KLEINFIELDER March 6, 1997 PROPOSED SERVICES Task E01 - Permitting and Pre-Field Activities It has been Kleinfelder's experience that this proposal contains sufficient detail and information to be submitted to the PHS/EHD to review and approve a boring/well permit. Kleinfelder can prepare a boring/well permit application, a proposed boring/well location map, and a health and safety plan for submittal along with this proposal to PHS/EHD. Additionally, the permits must be approved prior to drilling the borings. Following obtaining approval from the PHS/EHD, Kleinfelder will commence the actual field assessment. Task E02- Drilling of One Soil Boris One (1) soil boring will be advanced vertically to a depth of approximately 50 feet below surface grade(bsg). The boring will be advanced immediately south of the underground storage tank (UST) cluster. During the advancement of the boring, drilling returns and soil samples will be examined for lithologic classification and qualitative field screening, with an organic vapor analyzer (OVA). The OVA measures ionizable compounds in air in parts per million by volume (ppmv). Lithologic classification will be based on the Unified Soil Classification System (USCS). Currently, based on your correspondence and our experience, we anticipate groundwater in the vicinity of the project site to be present at a depth of 65 feet bsg. Therefore, at this time, we propose five (5) soil samples will be obtained from the boring for quantitative chemical analysis (the 15 foot, 25 foot, 40 foot, 45 foot and 50 foot samples). After collection, the soil sample will be labeled, Iogged on a chain-of-custody, and immediately stored in an iced cooler. Kleinfelder proposes submitting the five (5) soil samples from the boring to a State certified laboratory for the following analyses: • Total Petroleum Hydrocarbons Purgeable (Gasoline Range) by EPA Method 8015M15030 [TPH-G] • Benzene, Toluene, Ethylbenzene, Xylenes by EPA Method 8020/5030 [BTEX] • Total Extractable Petroleum Hydrocarbons as Referenced to Diesel (TPH-D) by EPA Method 8015M The samples will be analyzed on an accelerated laboratory schedule requiring approximately one week(five working days) for completion unless an optional 24 to 48 hour analytical turnaround is requested by the client at an additional charge. 20-3941-01.E01/207PE076 Page 2 of 8 0 1997, Kleinfelder, Inc.
