No Discharge Zones (NDZs) by State

These tables list states where the current no discharge zones (NDZs) for vessel sewage are located. The tables also include the names of the waterbodies, the type of designation, a link to the Federal Register Notice describing the action and a clickable map. Where available, you can click on the state name in the table to link to state webpages related to no discharge zones and/or pumpout facilities. NDZ designation types include:

  • 312(f)(3) protecting aquatic habitats where pumpout facilities are available;
  • 312(f)(4)(A) protecting special aquatic habitats or species; and
  • 312(f)(4)(B) protecting drinking water intake zones to protect human health.

In some cases, more than one state shares a waterbody and NDZ designation. These cases are listed by each state with the other state(s) also listed with it.
