Discharge of Sewage and Waste
The marine sanitation device (MSD) requirements on New York state waters are dictated by both the federal and state government, depending on where you boat.
- If you have a recreational vessel with installed toilet facilities, it must have an operable, U.S. Coast Guard–certified MSD on board.
- There are three types of MSDs.
- Types I and II MSDs are usually found on large vessels. Waste is treated with special chemicals to kill bacteria before the waste is discharged. Types I and II MSDs with “Y” valves that would direct the waste overboard must be secured so that the valve cannot be opened. This can be done by placing a lock or non-reusable seal on the “Y” valve or by taking the handle off the “Y” valve.
- Type III MSDs provide no treatment and are either holding tanks or portable toilets. Collected waste should be taken ashore and disposed of in a pump-out station or onshore toilet.
- All installed MSDs must be U.S. Coast Guard–certified.
