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.
