Environmental protection: groundwater contamination; limitation period for filing actions; revise. Amends sec. 20140 of 1994 PA 451 (MCL 324.20140).

This bill updates the timeline for filing legal claims related to groundwater contamination and environmental cleanup costs under Michigan's Natural Resources and Environmental Protection Act. It establishes specific deadlines for lawsuits seeking response costs or natural resource damages, generally requiring claims to be filed within six years of starting cleanup work or three years after cleanup finishes. The legislation also sets a fixed cutoff date of July 1, 1994, for claims involving incidents that occurred before that time, while clarifying that this rule applies retroactively to ensure consistency with the original law.
