No Discharge Zone
Commercial Vessel Pumpout:
NEP Grant Funding Solicitation
Ecology is soliciting applications for National Estuary Program
(NEP) grant funding for commercial vessel sewage disposal facilities or pumpout
stations in Puget Sound. It is designed to assist in the
installation of commercial pumpout stations to support sewage
pumpout for certain commercial vessels.
What is a No Discharge Zone or NDZ?
A No Discharge Zone (NDZ) is a designated body of water where the discharge of sewage (blackwater/toilet waste) from boats, whether treated or not, is prohibited.
Under existing federal regulations, treated sewage may be discharged anywhere in Puget Sound, and untreated sewage may be discharged as long as the boat is more than three miles from shore.
If a NDZ is established no boat, whether a freighter, a cruise ship, or a sailboat, could discharge anywhere within the designated NDZ. All boats and vessels would have to store their sewage until they could safely dispose of it at an onshore or mobile pumpout facility, or hold it until it can be discharged in the open ocean beyond 3 miles from shore. The United States
Environmental Protection Agency (EPA) Vessel Sewage website has more information on NDZs.
More than 80 NDZs have been established in 26 states, while
there are currently no NDZs in Washington State. A full listing
of these NDZs is provided on
EPA’s NDZ website.
