Environmental protection: water pollution; application requirements for new or increased discharge permit under NREPA; modify. Amends sec. 3112 of 1994 PA 451 (MCL 324.3112).

This bill modifies Michigan's environmental laws to require new or increased discharge permits to include proof of permission from any neighboring counties that might be affected by the discharge. Starting in 2025, applicants must submit a resolution from the impacted county's board of commissioners, and the state department must review applications within 30 to 90 days, treating them as complete if no decision is made by the deadline. The legislation also clarifies rules for oceangoing vessels by mandating specific permits for ballast water management to prevent the spread of aquatic nuisance species, while ensuring state standards remain at least as protective as federal requirements. Additionally, the bill sets strict timelines for the department to determine if applications are administratively complete and outlines the process for denying permits if county permission is missing.
