Environmental protection: cleanups; cleanup to residential and safe drinking water standards; require unless technically infeasible. Amends secs. 20118, 20120a, 20120b, 20120e & 20121 of 1994 PA 451 (MCL 324.20118 et seq.). TIE BAR WITH: SB 391'25, SB 385'25

SB 392 amends Michigan's Natural Resources and Environmental Protection Act to require cleanup of contaminated sites to meet residential and safe drinking water standards, unless technically infeasible. It directly affects property owners, developers, and environmental remediation companies responsible for cleaning up hazardous substance releases at contaminated sites. The bill mandates that cleanup efforts must restore affected aquifers to drinking water standards where possible, stop contamination spread, and comply with state/federal environmental laws. Exceptions allowing less stringent cleanup are only permitted if the Department of Environment, Great Lakes, and Energy documents technical infeasibility and confirms the alternative approach still protects public health and the environment. This bill updates existing cleanup standards (sections 20118, 20120a, and related sections) to strengthen residential and water quality protections.
