Associates Consultants believes there is a high probability that <br /> compressor blowdown oil is present in surface and subsurface soil <br /> in quantities and concentrations that would lead a prudent <br /> potential purchaser to conduct a more detailed assessment prior <br /> to the acquisition of this property. The following actions are <br /> recommended: <br /> The areas of oil-stained soil should be investigated to <br /> determine the extent of contamination and the possible <br /> need for remediation. A suggested approach would be to <br /> excavate the oil stained areas and remove the soil down <br /> to a depth beyond where oil can be detected by odor or <br /> observation with field instruments. The soil should be <br /> stockpiled on site on an impermeable membrane and <br /> covered to prevent erosion. Samples should be collected <br /> from the soil piles and analyzed for petroleum <br /> hydrocarbons by the method recommended by the Colorado <br /> Department of Environmental Protection (DEP) for <br /> determination of the appropriate disposal action. The <br /> bottom and sides of each excavation should be sampled <br /> for confirmation that the soil has been removed down to <br /> a "clean zone" as defined by the Colorado DEP <br /> regulations for petroleum hydrocarbons in soil. The <br /> results should be compared with the Colorado DEP action <br /> level and the stockpiled soil could, with regulatory <br /> approval, either be returned to the excavation if <br /> "clean" or disposed of offsite if "contaminated" . <br /> The AST should be emptied and removed. <br /> The trash piles should be cleaned up and disposed of <br /> properly. <br /> Scrap metal should be collected and sold for recycling. <br /> A determination should be made of the asbestos content <br /> of the pipe insulation and of the building insulation <br /> and roofing tars. <br /> The waste oils stored in drums and buckets on the <br /> property should be collected and sold to a recycler for <br /> reclamation and reuse. <br /> The lead acid battery should be removed and turned in <br /> for recycling. <br /> The stockpiles of limestone and magnetite should either <br /> be covered in place or sold and removed from the <br /> property. <br /> R.D. Piland and Associates Consultants believes that the level of <br /> inquiry presented in this assessment is adequate to identify that <br /> 24 <br />
