Correspondence - 4444 Shoreline Drive - 3/19/2026 t-rem-vic2-10 · LB 1529 · 7/15/22 March 19, 2026 VIA EMAIL Mike Hart 4444 Shoreline Drive, LLC 2510 Casco Point Road Orono, MN 55391 RE: No Further Action Determination for Soil Vapor Approval of RAP Implementation Report World Ferrari, 4444 Shoreline Drive, Spring Park MPCA Site ID: BF0002678 Billing ID: 32383 PIN: 1811723340003 Dear Mike Hart: The Minnesota Pollution Control Agency (MPCA) staff in the Voluntary Investigation and Cleanup (VIC) Program has been requested to provide a No Further Action Determination for releases identified at the World Ferrari site, located at the address referenced above (the Site). The Minnesota Pollution Control Agency (MPCA) staff in the Voluntary Investigation and Cleanup (VIC) Program has reviewed the documents submitted for the Site. Former businesses that operated at the 0.65-acre Site include an automotive repair and maintenance garage, a landscaping business, and a dock service business. 4444 Shoreline Drive, LLC purchased the Site in July 2023 and began operating a boat detailing business. A subsurface investigation was completed at the site in December 2023 that included the advancement of three soil borings. No staining, odors, or anthropogenic debris were observed in the soil borings. Groundwater was encountered at a depth of approximately 20 feet below ground surface (bgs). Three deep soil samples and one groundwater sample were collected and analyzed for volatile organic compounds (VOCs), diesel range organics (DRO), gasoline range organics (GRO), polycyclic aromatic hydrocarbons (PAHs), and Resource Conservation and Recovery Act (RCRA) metals. No VOCs, DRO, or GRO were detected in the soil or groundwater samples. Metals and PAHs detected in soil were within the range of typical background concentrations. The MPCA does not consider the metals detected in the groundwater sample to represent a release. In general, groundwater samples collected from temporary wells can result in detections of metals that are not representative of groundwater conditions, due to sediment entrained in the sample. Five sub-slab soil vapor samples were collected at the Site in September 2023 (non-heating season). Tetrachloroethene (PCE) was detected in one sample, from the northern (garage) portion of the building, at a concentration of 3,980 micrograms per cubic meter (μg/m3), exceeding the MPCA action level of thirty-three times (33X) its intrusion screening value (ISV). Other non-petroleum VOCs detected in the soil vapor samples are ubiquitous and not considered to represent a release to the environment. Mike Hart Page 2 March 19, 2026 The other four sub-slab vapor points were resampled in November 2023 (heating season); PCE was well below the vapor mitigation action level. A vapor mitigation system was required for the northern portion of the Site building. Three exterior soil vapor samples were collected at the Site in December 2023 (heating season) and July 2024 (non-heating season) to define extent and magnitude of contamination. The concentration of PCE, when detected, was less than its industrial ISV. For the purpose of this letter, the identified release at the Site is defined as PCE in soil vapor (Identified Release). This letter does not address petroleum-related compounds. Technical assistance for petroleum-related compounds may be obtained through the MPCA’s Petroleum Brownfield Program. Response actions completed at the Site are described in the Response Action Implementation Report prepared by Carlson McCain dated December 27, 2024 (Implementation Report). An active sub-slab depressurization system was installed in a portion of the existing Site building in July of 2024. Post- mitigation confirmation sampling was completed in November of 2024. Measurement of pressure field extension and analysis of confirmation samples indicate that the vapor mitigation system in the Site building is working as designed. To ensure ongoing protection against vapor intrusion, the vapor mitigation system in the Site building must be operated, monitored, and maintained in accordance with the Operation and Maintenance Plan prepared by Carlson McCain dated December 27, 2024. The Implementation Report is approved. Based on a review of the information provided to the MPCA, the MPCA staff will not request any further investigation or remediation of the Identified Release at the Site. Furthermore, the MPCA is issuing a determination to take no action under Minn. Stat. sections 115B.01-115B.18, with respect to the Identified Release. Specifically, the MPCA staff will not refer the Identified Release to the U.S. Environmental Protection Agency for inclusion in the Superfund Enterprise Management System (SEMS) database, to the State Site Assessment staff for evaluation, or to the MPCA Commissioner for the placement of the Site on the Permanent List of Priorities. An Environmental Covenant (EC) was recorded with Hennepin County on November 20, 2025, as document number 6170702. The EC documents the affirmative obligation to operate and maintain the vapor mitigation system. Please note that the Environmental Covenant requires submittal of an annual compliance report/letter by July 1st of each year to document the status and condition of the vapor mitigation system. The annual compliance report/letter should include supporting documentation, as appropriate, and be sent via electronic mail to instcontrols.pca@state.mn.us. Please include the MPCA Site name (World Ferrari) and identification number (BF0002678) on the submittal. This determination is subject to the following conditions and qualifications: 1. This determination is based solely on the results of the soil vapor investigation conducted on the Site. Due to the limited amount of information regarding other media, this letter does not address any conclusions or representations regarding the future need for further investigation or response actions relating to soil or groundwater. 2. This determination is contingent upon the continued commercial/industrial use of the Site. Changes in land use can create new potential exposure pathways for soil or soil vapor contaminants and should be preceded by a concurrent evaluation of Site conditions. Mike Hart Page 3 March 19, 2026 3. The soil vapor determination conveyed in this letter applies only to the existing building at the Site, as described in the Implementation Report. Future construction activities at the Site (e.g., potential addition, new building, new utility trenches, etc.) should be preceded by a soil vapor investigation within the footprint of the proposed construction area, so a vapor mitigation decision for the new feature can be made based on concurrent data. Please be advised that the determination made in this letter is subject to the disclaimers found in Attachment A. If you have any questions about the contents of this letter, please contact Madison Scheer, Project Manager, at 651-757-2821 or by email at madison.scheer@state.mn.us. Sincerely, Amy K. Hadiaris This document has been electronically signed. Amy K. Hadiaris, P.G.
