How to Submit Public Comments on Proposed Regulations

The federal rulemaking process includes a structured public participation stage that allows individuals, organizations, and businesses to formally influence regulations before they take effect. This page explains what public comments are, how the submission process works under the Administrative Procedure Act, the scenarios in which commenting is most consequential, and the distinctions that determine whether a comment is likely to affect agency decision-making. Understanding this process is foundational to navigating the regulatory agency rulemaking process and exercising rights under federal administrative law.

Definition and scope

Public comments are written submissions made to a federal agency during the open comment period that follows publication of a proposed rule in the Federal Register. The legal basis for this process is the Administrative Procedure Act (APA), codified at 5 U.S.C. § 553, which requires agencies engaged in notice-and-comment rulemaking to publish a notice of proposed rulemaking (NPRM), allow a public comment period of at least 30 days (though 60 days is standard practice for significant rules), and consider all substantive comments before issuing a final rule.

The scope of who may comment is broad: private citizens, corporations, trade associations, academic institutions, state and local governments, and foreign entities all have standing to submit comments on federal rulemakings. There is no requirement to demonstrate a personal stake or legal injury — participation is open by design. The process does not apply to interim final rules and emergency rulemaking, which bypass the notice-and-comment stage under good cause exceptions.

How it works

The submission process follows a defined sequence tied to the Federal Register publication cycle and the centralized federal docket system.

1. Locate the proposed rule. The Federal Register (federalregister.gov) publishes all NPRMs with a unique docket number (e.g., EPA-HQ-OAR-2023-XXXX). The Regulations.gov portal (regulations.gov) consolidates open comment periods across all federal agencies into a single searchable interface.

2. Identify the comment deadline. The NPRM specifies the closing date for comments. The Office of Information and Regulatory Affairs (OIRA) tracks significant rules through the unified regulatory agenda, which provides advance notice of upcoming NPRMs. Missing the deadline disqualifies a comment from the administrative record unless the agency exercises discretion to accept late submissions.

3. Draft the comment. Effective comments address the specific regulatory text at issue, cite factual or technical grounds for objection or support, and reference specific sections of the proposed rule. Comments that merely express approval or disapproval without substantive reasoning receive minimal weight in agency deliberations. The regulatory cost-benefit analysis published alongside major rules is a primary target for data-driven comment.

4. Submit through the official docket. Most agencies accept electronic submissions via Regulations.gov. Some agencies — including the Securities and Exchange Commission and the Federal Communications Commission — operate proprietary comment portals. Submissions must reference the correct docket number to enter the administrative record.

5. Track the agency's response. Agencies must address substantive comments in the preamble of the final rule. A comment that raises a significant issue the agency fails to address can form the basis for a challenge under judicial review of regulatory agency decisions.

Common scenarios

Individual citizen comments on environmental rules. The Environmental Protection Agency routinely receives tens of thousands of comments on air and water quality rules. For example, the EPA's 2015 Clean Water Rule received more than 1 million public submissions, as documented by the EPA docket. Volume alone does not shift an agency's analysis — only substantive technical or legal arguments carry formal weight.

Industry associations submitting technical data. Trade associations commonly submit comments bundled with proprietary studies, economic modeling, or engineering data. These submissions often run to hundreds of pages and are coordinated through outside counsel. Under OIRA and regulatory review, agencies reviewing economically significant rules (those with an annual effect on the economy of $100 million or more, per Executive Order 12866) face heightened scrutiny of how they respond to major industry objections.

Small businesses invoking the Regulatory Flexibility Act. The Regulatory Flexibility Act (5 U.S.C. §§ 601–612) requires agencies to analyze impacts on small entities and consider less burdensome alternatives. Comments from small businesses and regulatory agencies that document specific compliance cost impacts can trigger a formal regulatory flexibility review.

State and local governments seeking preemption clarity. State agencies frequently comment on federal rules that would preempt state law. These governmental comments receive particular attention under Executive Order 13132 on Federalism.

Decision boundaries

Not all comment submissions carry equal procedural weight, and understanding the distinctions determines where effort is best concentrated.

Substantive vs. non-substantive comments. A substantive comment raises a specific factual, legal, or technical challenge to the proposed rule — such as questioning the scientific basis of an exposure threshold or identifying a conflict with an existing statute. A non-substantive comment expresses a policy preference without supporting reasoning. Courts reviewing final rules under the APA's arbitrary-and-capricious standard focus on whether agencies adequately responded to substantive comments; non-substantive comments do not create reviewable error.

Formal rulemaking vs. informal rulemaking. Formal rulemaking (governed by APA §§ 556–557) involves trial-type hearings before an administrative law judge and is required only when a statute explicitly triggers that procedure. Informal rulemaking — the far more common track — uses written comments without adversarial hearings. The distinction matters because formal proceedings allow cross-examination of agency witnesses, a right that does not exist in standard notice-and-comment proceedings.

Pre-comment vs. post-comment intervention. Agencies often solicit advance input through Requests for Information (RFIs) or Advance Notices of Proposed Rulemaking (ANPRMs) before drafting an NPRM. Participating at the ANPRM stage, as catalogued in the unified regulatory agenda, gives commenters the opportunity to shape the rule's initial framing rather than respond to text already drafted. Post-comment intervention — petitioning a regulatory agency for rulemaking after a final rule is issued — is a separate procedural path governed by APA § 553(e).
