A No DIscharge Zone (NDZ) is a designated body of water that prohibits the discharge of treated or untreated boat sewage. It is also illegal to discharge untreated sewage from boats in all Virginia waters. The U.S. Coast Guard (USCG) regulations require all vessels to disable the Marine Sanitation Device (MSD) discharge capability while operating in waters designated as a NDZ.
