This bill proposes new regulations concerning the discharge of gray water from commercial houseboats in specific counties in Minnesota, namely St. Louis, Koochiching, and Lake County. It establishes that the Pollution Control Agency will not regulate sewage discharges from these houseboats, provided that the sewage does not contain toilet wastes. Instead, the responsibility for regulating these discharges will fall to the respective counties, which must ensure that their ordinances comply with the federal Clean Boating Act of 2008 and other relevant federal laws. The bill introduces a new section in Minnesota Statutes, chapter 115, specifically designated as [115.544] REGULATING DISCHARGES OF GRAY WATER FROM COMMERCIAL HOUSEBOATS IN CERTAIN COUNTIES. This legislative change aims to streamline the regulatory process for gray water discharges from commercial houseboats, allowing local counties to take charge of the regulations while adhering to federal standards.
