A <br /> Project Descriptions AddanBrown <br /> INVESTIGATION AND REMEDIATION OF HYDROCARBONS IN SOIL, <br /> COLORADO, UTAH AND WYOMING <br /> AdrianBrown was retained to perform a Phase I Environmental Site Assessment,Phase II Site <br /> Investigation, and site remediation for several sites in Colorado,Utah and Wyoming which our client <br /> was considering purchasing. The sites contained natural gas production,gathering and transmission <br /> systems. Facilities of concern at the sites included: compressors,dehydrators,waste oil tanks, <br /> condensate pits, landfills, meter stations, and underground storage tanks. <br /> The purpose of the Phase I Site Assessment was to identify the likelihood of past or ongoing releases of <br /> hazardous substances, including petroleum products,to soil,surface water or groundwater at any of the <br /> sites. The site assessment involved limited site inspections and a review of facility documents and <br /> records held by the existing owner of the sites.A number of facilities were identified as releasing <br /> hydrocarbons,typically via production pits and drip tanks. <br /> The Phase H Site Investigation involved borehole drilling, monitoring well installation, and soil and <br /> groundwater sampling and analysis at contaminated sites. Geologic and hydrologic models were <br /> developed for each of the sites investigated to evaluate the potential hazards associated with <br /> contamination. <br /> The Phase I and Phase 11 investigations resulted in substantial savings for our client with respect to the <br /> purchase agreement for the sites. <br /> Once the sites were purchased by our client,AdrianBrown was retained to perform necessary <br /> remediation.AdrianBrown worked with the Colorado Oil and Gas Conservation Commission <br /> (COGCC)to develop a classification system for the sites. The sites were classified as sensitive or non- <br /> sensitive based on interpretation of well records,topographical maps and state geologic reports. <br /> AddanBrown obtained approval to classify facilities in non-sensitive areas as exempt from <br /> remediation. <br /> Remediation of contaminated sites in sensitive areas was performed by excavating contaminated soil. <br /> The excavated soil was land farmed if possible. The soil was removed to an approved disposal facility if <br /> necessary. <br />
