Background

The former Wolverine Sole Plant, located at 485 Wolverine Drive NE, was historically used by Wolverine World Wide for shoe manufacturing operations, including shoe sole production. On December 1 and 2, 2021, EGLE staff and subcontractor, AECOM, collected groundwater samples from five monitoring wells installed at the property. The groundwater sample results identified PFOA and PFOS at concentrations exceeding Groundwater Cleanup Criteria in all five monitoring wells. PFNA was also detected in one monitoring well above Groundwater Cleanup Criteria.

This property is not located within the boundaries of the “North Kent Study Area” and is, therefore, not subject to the requirements of the Consent Decree (Court Case. 1:18-cv-00039; effective February 19, 2020) between the State of Michigan, Algoma and Plainfield Townships, and Wolverine. EGLE considers the contamination identified at this property to be a new and separate Part 201 issue that Wolverine is responsible to manage.

Groundwater flow is in a westerly direction to the Rogue River west of the property.

Historical Timeline

    • On December 1 and 2, 2021, EGLE staff and subcontractor AECOM, collected groundwater samples for PFAS analysis from five onsite monitoring wells.
    • On January 5, 2022, EGLE received the results which identified PFOS, PFOA, and PFNA at concentrations exceeding Groundwater Cleanup Criteria. PFOS was identified at a maximum concentration of 1,250 ppt.
    • On March 3, 2022, EGLE sent a Compliance Communication Regarding the Release at the Former Wolverine Sole Plant and requested Wolverine conduct response activities.
    • On April 18, 2022, Wolverine submitted a work plan for proposed response activities at the Former Sole Plant.
    • On May 4, 2022, EGLE provided Wolverine with comments on the work plan and requested that a Response Activity Plan (ResAP) be submitted with the results of the work plan investigation.
    • On September 30, 2022, Wolverine submitted a ResAP summarizing the results of the investigation and proposing next steps.
