Submitted via email and to Docket ID No. EPA-HQ-OW-2025- 0322 via regulations.gov and OW-Docket@epa.gov
To Whom It May Concern:
The undersigned organizations request that the Environmental Protection Agency (EPA) and Army Corps of Engineers (Corps) extend the comment period for the proposed rule published November 20 in the Federal Register titled “Updated Definition of ‘Waters of the United States,’” 90 Fed. Reg. 52,498 (Nov. 20, 2025). If not extended, the comment period will end on January 5, 2026, and will encompass several holidays during which most members of the public, technical experts, and other key stakeholders will not have sufficient time to review or participate meaningfully.
A comment period of at least 60 days is required in these circumstances. For one, Executive Order 12,866 specifies that “each agency should afford the public a meaningful opportunity to comment on any proposed regulation, which in most cases should include a comment period of not less than 60 days.” 58 Fed. Reg. 51735 (Sept. 30, 1993). Additionally, for Clean Water Act rulemakings like this one, section 101(e) of the Act specifies: “Public participation in the development, revision, and enforcement of any regulation, standard, effluent limitation, plan, or program established by the Administrator or any State under this Act shall be provided for, encouraged, and assisted by the Administrator and the States.” 33 U.S.C. § 1251(e).
In keeping with those directives, when the agencies most recently sought comment on changes to these regulations, the public comment period was 62 days. 86 Fed. Reg. 69372 (Dec. 7, 2021) (proposing revisions and setting comment period to close February 7, 2022). Notably, that comment period also spanned several holidays. Similarly, during the rulemaking process that led to the Trump administration’s “Navigable Waters Protection Rule,” commenters also had 60 days to participate. See 84 Fed. Reg. 4,154 (Feb. 14, 2019) (comment period ending April 15, 2019).
A reasonable comment period is also necessary considering the substance of the proposed rule. The agencies have proposed to dramatically reduce the number and extent of streams, wetlands, and other waters subject to the pollution prevention, control, and cleanup requirements of the Clean Water Act – a matter of major public concern. Additionally, the agencies’ proposal relies on new legal interpretations and technical concepts that the public should have an adequate opportunity to evaluate and weigh in on.
We respectfully request a prompt response to this request.
Sincerely,
A House Unbuilt
