Michigan House Bill 5485 aims to update and enhance the state's dam safety regulations for inland lakes. It proposes amendments to existing sections of the Natural Resources and Environmental Protection Act, specifically sections 31502 through 31523, and introduces new sections 31506a, 31509a, 31509b, 31517a, 31518a, 31518b, 31518c, 31518d, 31528a, and 31528b. These changes are designed to modernize safety standards, clarify maintenance requirements, and improve flood management and structural integrity of dams. The bill does not alter existing enforcement procedures but seeks to provide clearer guidelines for dam owners and operators.
