House panel hears competing testimony on Mundy Township ‘mega site,’ with residents warning of PFAS and developers touting jobs

The House Oversight Subcommittee on Corporate Subsidies and State Investments heard competing testimony October 25 about the proposed Advanced Manufacturing District (AMD) in Mundy Township, known locally as the “mega site.” Joanne Mendy, president of Mendy Engineering Solutions LLC and a Mundy Township resident, told the committee residents have organized in opposition and raised health and groundwater concerns; Flint and Genesee Economic Alliance executive director Tyler Rossmesler and Michigan Economic Development Corporation officials defended the site-preparation work and said the state-funded effort is meant to attract large manufacturing investment.

Mendy said the group sought baseline water testing at three Genesee County locations in 2023 and was denied by Eagle (the transcript identifies the response as citing “insufficient funds”).

Mendy outlined worker- and community-health concerns frequently raised about semiconductor manufacturing, including studies the group cites on…
