Michigan HB 4192 passes both chambers, heads to governor for signature

Michigan House Bill 4192 has passed both chambers of the state legislature and is now heading to the governor. The bill, sponsored by Rep. Greg VanWoerkom and eight co-sponsors, would modify groundwater discharge permit requirements under the state's 1994 natural resources and environmental protection act.

The House passed the bill with immediate effect on June 17, 2025, after adopting a substitute version. The bill was then referred to the Senate Committee on Energy and Environment. On June 2, 2026, the committee reported the bill favorably with a second substitute and referred it to the Committee of the Whole. No vote counts appear in the available action log (source: https://openstates.org/mi/bills/2025-2026/HB4192/).

The bill now goes to the governor, who may sign or veto it. No effective date beyond the House's immediate-effect passage has been specified in the available record.
