Environmental protection: water pollution; penalty for certain excess discharges into waters of the state; provide for. Amends sec. 3115 of 1994 PA 451 (MCL 324.3115) & adds secs. 3112d & 3119a.

This bill strengthens Michigan's environmental laws by requiring counties to notify neighboring counties at least 24 hours before discharging waste or sewage into shared waters, with permission needed from the affected county before the discharge occurs. It establishes new penalties for failing to provide this advance notice or for discharging without permission, including fines up to $500,000 that go into a state recovery fund. The legislation also clarifies existing rules by defining specific circumstances under which violations lead to criminal charges or civil fines, particularly when actions pose a substantial danger to public health or the environment. Additionally, it adjusts how courts determine liability for serious violations and mandates that certain fines be paid to the state's general fund while creating liens on the property of those found liable.
