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.).

This bill modifies Michigan's environmental laws to clarify how the state handles the cleanup of contaminated sites, specifically allowing for more flexibility when full restoration to drinking water standards is not technically possible. It requires that cleanup efforts generally meet safety standards and stop the spread of pollution, but it permits the Department of Environment, Great Lakes, and Energy to approve alternative solutions if achieving strict standards is impractical, too costly, or would cause more harm than good. The legislation also introduces specific conditions under which a site can be closed without meeting certain chemical limits, such as when natural processes will reduce contamination over time or when strict cleanup would have negative environmental impacts. These changes directly affect property owners, developers, and environmental agencies by defining the rules and exceptions they must follow when remediating hazardous waste sites.
