The Environmental Protection Agency has proposed removing federal discharge permits from a category of industrial vessels operating in ocean waters more than three miles from shore, and the public has until October 19 to comment.

The proposed rule, published September 4 and signed by Administrator Lee Zeldin, would rewrite part of the regulatory definition of the phrase discharge of a pollutant in the National Pollutant Discharge Elimination System regulations. The practical result, in the agency's own description, is that a vessel or other floating craft that is not secured to the seabed would no longer need an NPDES permit to add pollutants to the contiguous zone or the ocean.

The change is narrower than its title suggests and worth stating precisely. Nothing in the proposal touches waters of the United States or the territorial seas, which extend three miles from shore. Nothing changes for facilities anchored to the seabed. The affected zone begins where the territorial sea ends.

For coastal households and fishing communities in Alaska, Washington and Oregon, the concrete stake is what stops being measured. The vessels most directly affected are offshore seafood processors, and the permits they hold today carry sampling, monitoring, and public reporting requirements that would end.

One Phrase Removed from One Definition

The mechanics come down to a single qualifying phrase. Since 1979, the regulation at 40 CFR 122.2 has limited the Clean Water Act's vessel exclusion in the contiguous zone and ocean to craft "which is being used as a means of transportation." A processing trawler that works one general area rather than moving across the ocean is not transporting anything, so it has not needed a permit.

EPA proposes to delete that phrase, matching the regulation to the bare statutory text. Congress wrote the definition in two parts in 1972: additions of pollutants to navigable waters from any point source, and additions to the contiguous zone or ocean from any point source other than a vessel or other floating craft.

In its place, the agency would add a test based on physical attachment, under which a point source secured to the seabed would not count as a vessel. The proposal defines secured as permanently attached, substantially moored such that the facility cannot be moved without special effort from outside it, or a mobile offshore drilling unit engaged in drilling. Offshore oil and gas platforms tied to a wellhead by a riser stay regulated. Marine aquaculture facilities secured to the seabed stay regulated.

EPA rests the change on the Supreme Court's 2024 decision in Loper Bright Enterprises v. Raimondo, which directs agencies toward the best reading of a statute. The agency argues the 1979 preamble never explained why Congress treated pollutant additions differently by geography, and it says the current regulation is broader in scope than the law allows.

The Fleet That Would Stop Needing a Permit

The affected universe is small and specific. EPA counts 79 permittees under its Region 10 general permits for offshore seafood processing, covering federal waters off Alaska, Washington and Oregon. The agency estimates that about 71 of those are small businesses.

EPA estimates the proposal would save offshore seafood processors about $1.7 million a year in compliance costs and save the agency another $50,000 in administrative costs, for roughly $1.8 million in total annual savings. That works out to nearly $22,000 per establishment.

Those permits were not written casually. The consultation record for the Washington and Oregon general permit includes a Fish and Wildlife Service biological opinion, an essential fish habitat consultation with the National Marine Fisheries Service, coastal zone consistency decisions from both states, and a separate consultation with the Olympic Coast National Marine Sanctuary. The Alaska general permit fact sheet describes a provision governing seasonal discharge within one nautical mile of spectacled eider wintering critical habitat.

There is a forward-looking element the preamble itself treats lightly. On its own NPDES regulations page, EPA writes that the proposal would apply to current activities such as certain seafood processors and to future activities such as potential deep seabed mining. That second category involves no permittees today and no cost estimate in the analysis, but it is the agency's stated scope. A short agency fact sheet accompanies the proposal.

Monitoring Data That Would Stop Being Collected

EPA does not claim the change is costless, and its candor here is the most useful part of the document for readers weighing in.

The agency writes that potential foregone benefits could include the current management of localized seafood processing discharges beyond three miles, with possible effects on marine species and receiving-water quality. It adds that the proposal would eliminate permit-required monitoring and reporting, "potentially reducing the information available for public review."

The specific obligations that would end are listed in the rule: notices of intent and termination, discharge monitoring reports, noncompliance reports, annual reports, best management practices plans, analytic sampling requirements, and recordkeeping. EPA's paperwork estimate for the affected entities drops to zero respondents and zero burden hours.

How much that loss matters is a contested judgment rather than a settled one. In its own permitting analysis for the Alaska fleet, EPA concluded that impacts to the seafloor and water quality from discharging whole or ground fish were expected to be fairly minimal. The counterweight sits in the agency's own preamble, which flags possible effects on marine species and receiving-water quality once the discharges are no longer managed under permit. Comments that engage that specific trade-off with evidence will carry more weight than assertion in either direction.

Other statutes would continue to apply offshore. EPA names the Marine Protection, Research, and Sanctuaries Act, the Oil Pollution Act of 1990, and the Vessel Incidental Discharge Act, and says it does not intend to change the scope of any of them. Those frameworks are not equivalent to an NPDES permit, and they do not carry the same discharge monitoring reports.

Comment Routes and the Hearing That Is Not Described

Comments go to the rulemaking docket at regulations.gov under docket number EPA-HQ-OW-2026-6965, by email to the Office of Water docket, or by mail to EPA's Docket Center in Washington. Submissions cannot be edited or removed once filed, and personal information may be posted.

One procedural gap is worth noting. The rule's DATES section tells readers to consult the supplementary information for details about a public hearing, but the public participation section that follows describes only written comments and gives no hearing date, format or registration path. Anyone planning to testify rather than write should confirm with the agency contact listed in the rule.

The proposal is classified as a deregulatory action under Executive Order 14192, and EPA has certified that it will not have a significant economic impact on a substantial number of small entities because it relieves burden rather than imposing it. The agency says it plans to consult with tribal officials, noting that it directly implements the NPDES program in Indian country everywhere except Maine.

Nothing takes effect yet. This is a proposal, and EPA must review comments and publish a final rule before any permit obligation changes. Nature World News will report the final rule and any litigation that follows. Fishing crews, processors and coastal residents who want the underlying numbers can find the draft economic analysis filed in the docket alongside the rule.

What Readers Want to Know

What is EPA proposing to change? It would remove the phrase limiting the Clean Water Act vessel exclusion to craft used as a means of transportation, so that unsecured vessels discharging in the contiguous zone or ocean would no longer need an NPDES permit.

Does this affect water near the beach? No. The proposal does not apply to waters of the United States or the territorial seas, which reach three miles offshore. It applies to the contiguous zone and ocean beyond that line.

Who would actually be affected? EPA identifies 79 permittees under its Region 10 general permits for offshore seafood processing off Alaska, Washington, and Oregon, most of them small businesses. Offshore oil and gas platforms and aquaculture facilities secured to the seabed would remain permitted.

What would stop being reported? Discharge monitoring reports, noncompliance reports, annual reports, best management practices plans, sampling requirements and recordkeeping. EPA acknowledges this could reduce information available for public review.

Are there other laws still covering these discharges? Yes. EPA cites the Marine Protection, Research, and Sanctuaries Act, the Oil Pollution Act, and the Vessel Incidental Discharge Act, though none imposes the same permit monitoring regime.

When is the deadline and how do I comment? Comments are due October 19 through regulations.gov under docket EPA-HQ-OW-2026-6965, or by mail or email to EPA's Office of Water docket.

Is this final? No. It is a proposed rule. EPA must consider comments and issue a final rule before anything changes.
