This bill updates Michigan's environmental cleanup laws by clarifying definitions for terms like agricultural property and hazardous substance background levels. It requires property owners to conduct specific environmental assessments before buying or occupying land and establishes new standards for determining when soil contamination is safe for residential use. The legislation also adds new sections to the Natural Resources and Environmental Protection Act while repealing an outdated provision. These changes aim to streamline the process for cleaning up contaminated sites and provide clearer guidelines for developers and landowners.
