Environmental protection: groundwater contamination; location guidelines for wastewater discharge; provide for. Amends sec. 3112 of 1994 PA 451 (MCL 324.3112).

This bill updates Michigan's environmental regulations by clarifying rules for wastewater discharge and adding specific permit requirements for oceangoing vessels. It requires that any waste discharge into state waters must occur at least one mile upstream from the nearest dwelling and mandates that vessels operating in Michigan ports obtain permits demonstrating compliance with federal aquatic nuisance species rules. The legislation also sets strict timelines for the state department to review permit applications and outlines procedures for permit modification, suspension, or revocation if pollution violations occur. Additionally, it establishes fee structures for vessel permits and allows the department to adopt more protective standards than federal rules for preventing aquatic nuisance species in the Great Lakes.
