Phase II Environmental Investigation STLOU 137941 Saint Louis Park ES-1

Executive Summary Short Elliott Hendrickson Inc. (SEH®) was retained by the City Saint Louis Park (the City) to conduct a Phase II Environmental Investigation (Phase II) for the proposed Walker Pond II Project in Saint Louis Park, Minnesota (herein referred to as “project area”). The project area location is depicted on Figure 1.

The City plans to construct two lined storm water filtration basins that will treat storm water runoff from adjacent developed urban land. The purpose of the project is to create shared or stacked infrastructure where the filtration basins will treat storm water from multiple privately owned parcels. The City’s goal with this project is to attract redevelopment on the adjacent parcels by providing storm water treatment on public land. The filtration basins will be lined to provide a separation of storm water from impacted soil and ground water that lies below. The preliminary design layout is available in Appendix A.

The investigation included four soil borings (SS-01 through SS-04) completed to a maximum depth of 25 feet below ground surface (bgs). Two soil borings were completed within the currently proposed east filtration basin in the area of the former Reynolds Welding building. The other borings were located in the proposed west filtration basin and near the storm water discharge area on the western portion of the project area.

Soils encountered generally consisted of sandy outwash deposits below sand fill material. Fill material was present in every boring to a maximum depth of 17 feet bgs. Deep fill is located on the eastern portion of the project area as result of previous construction activities associated with the Walker Street project. Groundwater was encountered as shallow as 9.5 feet bgs.

Six soil samples were collected for laboratory analysis. Soil sample SS-02-3 indicates shallow fill in the proposed east filtration basin and in the area of the former Reynolds Welding building is impacted with petroleum compounds and non-petroleum compounds. Soil is contaminated with Diesel Range Organics (DRO) (148 mg/kg), lead (474 mg/kg), Benzo(a)pyrene (BaP) equivalent (1.931 mg/kg), and Tetrachloroethene (PCE) (0.92 mg/kg). The sample was analyzed for TCLP lead and the result was 2.8 mg/L, which is below the EPA Lead TCLP Hazardous Level of 5.0 mg/L.

One groundwater sample was collected from boring SS-04 located on the western portion of the project area. Groundwater was observed at 9.5 feet bgs and the concentration of DRO (212 μg/L) is above the Minnesota Department of Health drinking water standard of 200 μg/L.

Review of previous environmental documentation for the former Reynolds Welding site that occupied the eastern portion of the project area indicates soil is impacted with DRO up to 445 mg/kg, BaP equivalents up to 14.96 mg/kg, PCE up to 6.5 mg/kg and TCE up to 4.72 mg/kg. Groundwater was observed to be 16 to 23 bgs. TCE was detected in groundwater at 26.3 μg/L. Soil vapor results indicated Methylene Chloride up to 1,117 micrograms per cubic meter (μg/m3), PCE up to 3,910 μg/m3 and TCE up to 489 μg/m3. Based on Demolition Plans for the former Reynolds Welding building efforts were made to minimize soil disturbance and this contamination remains below the fill on-site.

SEH recommends completion of a Response Action Plan (RAP) and special provisions that address contingencies and proper screening, handling and disposal of regulated soil that may be encountered during construction activities for the project. SEH further recommends that the City enter the MPCA Voluntary Remediation Program for approval and assurances of the Response Actions.
