MI SB0717

Amends Michigan's underground storage tank (UST) liability and corrective action framework by modifying definitions, liability standards, and consultant qualification requirements in the Natural Resources and Environmental Protection Act.

Establishes alternative institutional control mechanisms to traditional restrictive covenants, including compliance with local ordinances, state transportation department licenses for contamination in public highways, and reliance on public highway existence if certain conditions are met.

Clarifies liability protections for government entities acquiring property involuntarily and exempts lessees using property for retail, office, or commercial purposes from liability unless otherwise responsible for the contamination.

Requires property owners to conduct baseline environmental assessments within 45 days of purchase or occupancy and provide results to the department within 6 months to avoid liability for pre-existing contamination.

Mandates that department employees overseeing corrective action activities and conducting audits receive formal training and demonstrate proficiency in risk-based corrective action (RBCA) methodology.
