Important: U.S. Coast Guard regulations require that boats
have a sanitation system on board to control pollution. Waste
is to be stored in a holding tank or other device so it can be
properly disposed of at a shore facility. Discharging this waste
overboard in U.S. lakes, rivers, bays, and sounds and within 3
miles of shore in international waters is prohibited. Check with
the Coast Guard regarding regulations in your area.
