Opportunity Area 1 Opportunity Area 1 is comprised of five Sites (1-1 through 1-5) located east of Cleveland Avenue and south of County Road C-2. Sites I-I through 1-3 encompass about 10.17 acres and are currently occupied by a truck terminal/service and parts business. These sites are referred to as the Dorso Site. These or similar businesses occupied this Area since the early 1960s. Sites 1- 4 and 1-5 will be discussed with the Opportunity Area 2 Sites. The results of previous environmental site assessment activities that address this Area include the following: . Limited Environmental Site Assessment Report> DPRA> Project No. 5781.0003.0001, July> 2002. . Phase I Environmental Site Assessment, AET, Project No. 03-01578.2814, August 11, 2003. (Sites 1-1 through 1-3) . Groundwater Evaluation Report, DPRA, Project No. 5781.0003.0001, August, 2003. . Supplemental Groundwater Evaluation Report, DPRA, Project No. 5781.0003.0001, August, 2004. Environmental Conditions identified at Area 1 include the following: . Underground Storage Tank (UST) and Leaking Underground Storage Tank (LUST) site. . Use as a truck terminal (vehicle servicing, petroleum products, parts cleaners, floor drains, oil-water separators, etc.). . Septic tank/cesspool initially serviced facility. . Part of Area has been filled. . Staining of parking surface. . Trichloroethylene (TeE) impacts to glacial aquifer near southeast corner of Site 1-3. . Adjacent Minnesota Ponution Control Agency (MPCA) Voluntary Investigation and Cleanup (VIe) and LUST sites. Additional environmental assessment to be performed may include the following: . Assess UST and LUST basins to identifY magnitude and extent of subsurface impacts. . Assess areas of oil-water separators, drains, underground piping, etc. within buildings for evidence of subsurface impacts. . Assess area of septic tank/cesspool for evidence of subsurface impacts. . Assess fill. . Assess areas of surface staining for evidence of subsurface impacts. . Assess the shallow subsurface soil and groundwater (depths of 0 to 20 feet) in area where solvent contamination, specifically TCE, has impacted the glacial aquifer, and if necessary, assess the glacial aquifer for TCE impacts. . Assess areas that are adjacent to VIC and LUST sites for evidence of subsurface impacts.
