Cleanup of soil and groundwater at the Duell & Gardner site in Dalton Township, Mich., is complete, and the state now oversees and monitors the site.
Previous chemical manufacturing operations at the site contaminated the soil and groundwater with metals and volatile organic compounds.
EPA said cleanup is complete at the site and has removed it from the NPL.
At least four subsidiaries of United Technologies Corp. have been named as defendants in lawsuits seeking damages from alleged PFAS contamination.
The grant will allow the state to contribute to a nationwide health study of PFAS and will allow for the expansion of a multiyear effort underway in West Michigan.
During a daylong virtual public hearing on October 10, environmental activists spoke out against proposed CCR changes.
The proposed changes include revising one of the criteria in the coal ash beneficial use definition and the requirements applicable to piles of coal ash.
The partial deletion pertains only to the groundwater portion of the site; the landfill and landfill gas components will remain on the Superfund list.
One action is an advanced notice of proposed rulemaking allowing public input on adding PFAS to the Toxics Release Inventory toxic chemical list.
MDC alleges the state’s Department of Energy and Environmental Protection is responsible for PFAS contamination in groundwater from a closed landfill.
