Bill > HB4641

This bill proposes to remove the existing prohibition against establishing dark sky preserves in Michigan's Upper Peninsula and simultaneously eliminate the specific list of currently designated dark sky preserves. A dark sky preserve is a designated area that limits light pollution to protect the nighttime environment and enable better astronomical observations. The bill would modify section 75102 of the Natural Resources and Environmental Protection Act by removing the paragraph that previously listed eight specific dark sky preserves (including locations in Lenawee, Emmet, Huron, Presque Isle, Alpena, and Cass Counties) and the explicit restriction preventing new dark sky preserves in the Upper Peninsula. By removing these provisions, the bill effectively opens the possibility for creating new dark sky preserves anywhere in Michigan, including the Upper Peninsula, without the previous geographical limitations. This change could potentially allow local governments, parks, and conservation organizations more flexibility in establishing areas dedicated to preserving dark night skies and protecting nocturnal environments.
