PLAINFIELD TOWNSHIP, Mich. — Wolverine Worldwide released its plan for dealing with PFAS contamination at the company's former dumping site on House Street.
In a proposal to the Michigan Department of Environment, Great Lakes, and Energy, Wolverine says it will use two approaches to prevent more PFAS from leaking into the groundwater.
The first step is called strategic capping, which involves installing a membrane over the areas most contaminated with per- and polyfluoroalkyl substances. Those membranes are designed to hold PFAS, which are man-made chemicals that require special filtration systems to remove from water.
The second approach, called phytoremediation, will have Wolverine plan up to 4,000 trees on the site. The company says over time the trees will pull the PFAS out of the ground. Wolverine says the plan will allow the 76-acre site to be turned into a public greenspace with the possibility of limited use nature trails being built in the future.
In a post on the community blog, Wolverine says the plan took into account the feedback from neighbors in Plainfield and Algoma Townships along with local and state leaders.
Now Wolverine's plan must be approved by EGLE. The company says it could have the membrane and trees in place after a year and a half of work.
If the proposal is rejected Wolverine says the consent decree made between it and EGLE would require the creation of a surface cap over nearly 30 acres. That project could take two and a half years.
