County regulation of gray water discharges from commercial houseboats provision in certain counties

This bill shifts regulatory authority for gray water discharges (non-toilet wastewater) from commercial houseboats in St. Louis, Koochiching, and Lake Counties from the state Pollution Control Agency to those counties. It prohibits the state agency from regulating such discharges in these counties and requires counties to adopt local rules compliant with the federal Clean Boating Act of 2008. The bill specifically applies to commercial houseboats operating in those three counties and excludes discharges containing toilet waste. This is a policy change transferring local regulatory responsibility without altering federal requirements.
