Phase II Environmental Site Assessment 2534 Kenzie Terrace WSB Project No. R-020198-000 Page 1 1. Introduction WSB was retained by the City of Saint Anthony Village (City) to conduct a Phase II Environmental Site Assessment (ESA) at the vacant property located at 2534 Kenzie Terrace in St. Anthony, Minnesota (Site). The Site consists of Hennepin County Parcel 0702923230015 and totals approximately 0.32 acres. The Site location is depicted in Figure 1. The objective of the Phase II ESA was to investigate the recognized environmental conditions (RECs) identified in the Phase I ESA completed by WSB and dated March 28, 2022 (see Section 1.2). WSB understands that the investigation results will be used for future Site transaction/acquisition purposes. This Phase II ESA has been prepared exclusively for the City. No additional parties can rely on the information in this report without written permission from WSB. 1.1 Site Description and Background The Site was historically occupied by a filling station and car wash from before 1938 until approximately the 1960s. By the early-1970s, the Site was cleared and graded. The Site has been developed as vacant lot since the late-1970s. The Site is in a commercial and residential district of St. Anthony with commercial properties to the east and northwest and residential properties to the north and south. 1.2 Previous Investigations WSB completed a Phase I ESA for the Site, and the results of the assessment were summarized in a report dated March 28, 2022 (2022 Phase I ESA). The 2022 Phase I ESA identified the following RECs in connection with the Site: REC-1: Former Property Filling Station Based on a review of historical aerial photographs and city directories, the Site was developed with a filling station (Kenzie Company Gas Station) as early as 1938 until the late-1960s. By the early-1970s, the Site was cleared and graded. The former filling station is not listed under any regulatory databases and details related to the former underground storage tanks (USTs), including the size and contents, are not known. Further, documentation regarding the removal of UST systems, fueling lines, dispensers, etc. are not available. Undocumented petroleum releases may have occurred at the former UST system and associated filling station activities resulting in soil, groundwater, and/or soil vapor impacts at the Site. It is also possible that the USTs remain in-place at the Site and were never removed. The former Site filling station is considered a REC. REC-2: Former East Adjacent Dry Cleaner with Documented Contamination (MPCA ID BF0001960) The east adjacent property located at 2510/2512/2520 Kenzie Terrace is associated with active Brownfields/Voluntary Investigation and Cleanup (VIC) listing BF0001960. The east adjacent property was historically occupied by a dry cleaner (Popko Cleaners & Tailors) from approximately 1983 to 1988. The dry cleaner occupied the current building at 2510/2512 Kenzie Terrace, located approximately 15 feet from the Site. A subsurface investigation completed in July 2021 identified elevated concentrations of non-petroleum volatile organic compounds (VOCs), including tetrachloroethene (PCE) and trichloroethene (TCE), in groundwater and/or sub-slab soil vapor at the east adjacent property. Based on the sub-slab soil vapor results, the MPCA required an active vapor mitigation system to be installed on an expedited schedule at both property buildings in October 2021. The 2021 subsurface investigation also identified elevated concentrations of diesel range organics (DRO) in groundwater approximately 10 feet east of the Site.
