File No. 20-3978-01.P02 wL■ KLEINFELDER <br /> November 5, 1996 <br /> Kleinfelder proposes to conduct a visual inspection of these two structures to establish if <br /> floor drains are present within either structure. If floor drains are present, Kleinfelder <br /> proposes to core through the concrete foundation slab and collect soil samples from <br /> beneath the slabs for analysis. If no floor drains are present, soil samples will be <br /> collected from the perimeter of each structure using a hand auger. A maximum of four <br /> hand auger borings at each structure (8 total) will be advanced. <br /> Flammable Materials Storage <br /> A temporary storage trailer was formerly located adjacent and south of the Ag shop. The <br /> trailer was used to store flammable materials. The former trailer location is unpaved. <br /> Kleinfelder proposes to collect shallow depth and surface soil samples in the vicinity of <br /> the former flammable materials storage trailer using a hand auger. Kleinfelder proposes <br /> two hand auger borings at the flammable materials storage trailer location. The soil <br /> samples will be collected at the surface (0 to 6 inches) and at depths of two and five feet <br /> below grade. <br /> Discoloration and Odor in Barn <br /> A strong petroleum odor and visible staining of the wood floor was present within the <br /> barn. Kleinfelder proposes to collect shallow depth and surface soil samples from <br /> beneath the visibly stained flooring using a hand auger. A maximum of three hand auger <br /> borings will be advanced in the barn. The soil samples will be collected at the surface (0 <br /> to 6 inches) and at depths of two and five feet below grade. <br /> TECHNICAL APPROACH FOR FIELD ACTIVITIES <br /> Underground Storage Tank and Septic Systems <br /> Drilling Permit and Work Plan Submittal <br /> Kleinfelder will collect soil samples and Hydropunch IITI water samples from borings. <br /> The PHS/EHD requires a workplan and boring permit application for exploratory soil <br /> borings drilled for site assessment purposes. The proposed soil/Hydropunch IIT^" borings <br /> will require boring permits. Additionally, because closure will be requested for the <br /> former UST location, a workplan will be submitted to the PHS/EHD for review. <br /> Kleinfelder will also prepare a health and safety plan for use in the field. <br /> Drilling of Borings and Soil Sample Collection <br /> A total of six Hydropunch IIT"' soil borings will be drilled in the vicinity of the <br /> underground storage tank and septic systems (refer to Plate 2). One boring will be <br /> advanced through the center of the former UST location (B-1). A second boring will be <br /> advanced along the product piping run adjacent to the former fuel dispenser (B-2). The <br /> former UST and fuel dispenser locations were established by reviewing existing site <br /> plans, and our Phase I ESA site reconnaissance. <br /> 20-3978-01.P02IMP960129 Page 3 of ©1996, KleinJleder, Inc. <br />
