What is the Law regarding boat discharges in LIS?
Under U.S. Coast Guard regulations, if your boat has an installed toilet, you are required to have a certified Marine Sanitation Device (MSD). Type I or II MSDs treat sewage chemically and discharge it into the water. Type III MSD’s include holding tanks that retain and discharge human body waste. It is illegal to discharge any untreated waste into Long Island Sound or any of Connecticuts waters. Type III MSD’s must be emptied at pumpout facilities or may be directly discharged three nautical miles past the southern shore of Long Island. For boats that have a portable toilet, sewage must be disposed of at a pumpout facility or dump station.
