No-Discharge Zones (NDZs) by State

This page provides links to non-EPA web sites that provide additional information about state-level no-discharge zone and "clean" boating programs. You will leave the EPA.gov domain and enter another page with more information. EPA cannot attest to the accuracy of information on that non-EPA page. Providing links to a non-EPA Web site is not an endorsement of the other site or the information it contains by EPA or any of its employees. Also, be aware that the privacy protection provided on the EPA.gov domain (see Privacy and Security Notice) may not be available at the external link. The following links exit the site Exit

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 NDZs 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.
