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 1-1 through 1-3 encompass about 10.17 acres and are currently occupied by a truck terminaliservice 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 discussedwith the Opportunity Area 2 Sites. The results of previous environmentalsite assessment activities that address this Area include the following: « Limited Environmental Site Assessment Report, �PRA, Project No. 5781.0003.0001, July, 2002. • Phase I Environmental Site Assessment, AET, Project No. 03-0157$.2$14, 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. 5781A003.0001, 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 tmck terminal (vehicle servicing, petroleum products, parts cleaners, floor drains, oil-water separators, etc.). � Septic ta,�klcesspoa� initially serviced facility. . Part of Area has been filled. • Stainingofparkingsurface. Trici�loraethyl8na (TCE) impacts to glacial aquifer near southeast comer of Site 1-3. . Adjacent Minnesota Pollution Control Agency (MPCA) Voluntary Investigation and Cleanup (VIC) and LUST sites. a- , 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/cesspoai 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.
