2018 Investigation Timeline

2018 Investigation Timeline

  • In January 2018, EGLE filed a legal complaint against Wolverine under the federal Resource Conservation and Recovery Act (RCRA) and state law, including Part 201 (Environmental Remediation) in the United States District Court for the Western District of Michigan.  In the complaint, the state seeks orders that Wolverine institute protective measures to mitigate risks to public health, continue environmental investigations, address PFAS contamination in ground and surface water and pay for the state’s past and future costs associated with enforcement of state clean-up laws.
  • In late Spring 2018, Wolverine began conducting a source area investigation on the House Street site under a United States Environmental Protection Agency (USEPA) Unilateral Administrate Order (UAO) to address the non-PFAS contamination and is sampling for PFAS for EGLE as part of those investigation activities.  This investigation was completed in late November 2018, with a summary report due to the agencies in late February 2019.

  • On November 3, 2018, EGLE completed reviewing Wolverine’s revised filter operation and maintenance plan and provided comments back.
  • In late November 2018, the USEPA and EGLE released a status update factsheet, providing residents an update on the investigation and announcing the January town hall meeting.
