Civil procedure: statute of limitations; accrual of cause of action for groundwater contamination cases; revise. Amends 1961 PA 236 (MCL 600.101 - 600.9947) by adding sec. 5830.

This bill modifies Michigan's civil laws to update how the legal clock starts for lawsuits involving hazardous substances like groundwater contamination. Under the new rule, a victim's right to file a claim begins when they discover the harm or when they should have reasonably known about it, rather than from the date the contamination initially occurred. This change directly affects individuals or businesses seeking damages for environmental injuries by aligning the start of the legal filing period with the discovery of the problem. The provision simplifies the process for plaintiffs by ensuring the statute of limitations reflects when the issue became known to them.
