Phase II Environmental Site Assessment 2534 Kenzie Terrace WSB Project No. R-020198-000 Page 2 Based on the active regulatory status and proximity to the Site, it is possible that the petroleum and chlorinated solvent impacts at the east adjacent property have migrated onto the Site via groundwater migration. The documented petroleum and chlorinated solvent contamination at the east adjacent property are considered a REC. REC-3: Former Northwest Adjacent Dry Cleaner and Filling Station with Documented Contamination (MPCA IDs BF0000517, SA0000618) The northwest adjacent property located at 2401 Lowry Avenue Northeast is associated with active Brownfields/VIC listing BF0000517 and Site Assessment listing SA0000618. The northwest adjacent property was occupied by a filling station (Lowry Grove Filling Station) from approximately 1938-1941 and a dry cleaner (Pilgrim Cleaners) in the 1960s and 1970s. The property was redeveloped with the current bank building in 1979. A subsurface investigation completed at the property in August and October 2017 identified elevated concentrations of silver, dibromochloromethane, cis-1,2-dichloroethene (cis-1,2- DCE) and polycyclic aromatic hydrocarbons (PAHs) in soil. Concentrations of benzene, PCE, TCE, and cis-1,2-DCE were identified in groundwater at concentrations greater than their respective Minnesota Department of Health (MDH) Health Risk Limits (HRLs). Elevated TCE concentrations were identified in sub-slab soil vapor samples collected from within the current bank building footprint. Further, elevated concentrations of non- petroleum VOCs, including PCE, TCE, and cis-1,2-DCE, were identified in soil vapor samples collected across the property parking lot. Based on the active regulatory status, distance to the Site (within 100 feet), and presumed direction of groundwater flow to the south, it is possible that the petroleum and chlorinated solvent impacts at the northwest adjacent property have migrated onto the Site via groundwater migration. The documented petroleum and chlorinated solvent contamination at the northwest adjacent property are considered a REC. REC-4: North Adjacent Property with Documented Contamination (LS0018847, BF0000058, BF0001790) The north adjacent property located at 2501 Lowry Avenue Northeast is associated with active Brownfields/VIC listing BF0001790, inactive Brownfields/VIC listing BF0000058 and inactive leak listing LS0018847. A petroleum release was reported at the north adjacent property in August 2012 during the removal of one 12,000-gallon fuel oil UST. The UST was reportedly installed in 1965. The MPCA issued closure of the leak site in March 2013 following the completion of a limited site investigation. Additional subsurface investigations were completed at the north adjacent property prior to redevelopment in May 2016 and January 2021. The May 2016 investigation identified elevated concentrations of TCE, PCE, and cis-1,2-DCE in groundwater and elevated concentrations of PCE in soil vapor. The January 2021 investigation also identified elevated PCE and benzene concentrations in soil vapor at the property. Based on the soil vapor results, the MPCA required a vapor mitigation system to be installed at any proposed buildings at the property. The documented chlorinated solvent impacts were presumed to be associated with former dry cleaners located west (Pilgrim Cleaners) and south (Popko Cleaners & Tailers) of the property. Based on the active regulatory status, distance to the Site (within 100 feet), and presumed direction of groundwater flow to the south, it is possible that the petroleum and chlorinated solvent impacts at the north adjacent property have migrated onto the Site via groundwater migration. The documented petroleum and chlorinated solvent contamination at the north adjacent property are considered a REC.
