Discharge of Sewage and Waste
- It is illegal for a vessel to discharge sewage into the waters of Vermont.
- All vessels equipped with a marine toilet must have a waste-water holding system to prevent the discharge of waste products into surrounding waters.
- Any holding tank that is designed to allow discharge into the water (such as those with a “Y” valve) must have the openings sealed shut and any discharge lines, pipes, or hoses must be disconnected and stored while the vessel is on Vermont waters.
- Residential use of vessels with overnight sleeping facilities is prohibited on waters that do not have sanitary waste pump-out facilities.
There are three types of MSDs.
- Types I and II MSDs are usually found on large boats. 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. They have the least effect on the environment since collected waste is discharged on shore into a local sewage treatment facility.
