The federal rulemaking process is the sequence federal agencies follow to turn a statute passed by Congress into a specific, enforceable regulation. In its standard form, an agency drafts a proposal, publishes it in the Federal Register as a Notice of Proposed Rulemaking, collects written comments from the public, reviews and responds to those comments, publishes a final rule, sends the required report to Congress, and only then does the rule take effect and get codified in the Code of Federal Regulations. Each stage carries legal requirements under the Administrative Procedure Act (APA), and several of those stages are also where the public, regulated businesses, and Congress can push back.
What Starts a Rulemaking
A rulemaking usually begins because Congress passed a new law that directs the agency to write regulations, a court ordered the agency to act, an internal review flagged a problem, or someone outside the agency filed a petition. Under the APA, any person has the right to petition a federal agency to create, amend, or repeal a rule.1Office of the Law Revision Counsel. 5 USC 553 – Rule Making The agency has to respond, but it decides whether the petition warrants action.
Before drafting anything, the agency does preliminary analysis. The Regulatory Flexibility Act requires an initial analysis whenever a proposed rule could significantly affect a substantial number of small businesses, nonprofits, or local governments.2U.S. Small Business Administration Office of Advocacy. Regulatory Flexibility Act Executive Order 12866 directs agencies to assess both the costs and benefits and to adopt the rule only when the benefits justify the costs.3U.S. Department of Health and Human Services. Executive Order 12866 – Regulatory Planning and Review
For particularly complex or novel issues, the agency may publish an Advance Notice of Proposed Rulemaking (ANPRM) to ask for early public input before it has settled on an approach. An ANPRM is optional and does not replace the later formal proposal. If you want to see what agencies are working on before anything is proposed, the Unified Agenda of Regulatory and Deregulatory Actions is published twice a year by the Office of Information and Regulatory Affairs and lists planned and recently completed regulatory actions across the executive branch.4RegInfo.gov. Current Unified Agenda of Regulatory and Deregulatory Actions
The Notice of Proposed Rulemaking
The formal public process begins when the agency publishes a Notice of Proposed Rulemaking (NPRM) in the Federal Register. The NPRM has to cite the legal authority under which the agency is acting and must include either the full text of the proposed rule or a description of the subjects and issues involved.1Office of the Law Revision Counsel. 5 USC 553 – Rule Making In practice, most NPRMs go well beyond that statutory minimum. They publish the full regulatory text plus a detailed preamble laying out the problem, the agency’s reasoning, and the data behind the approach.
When Agencies Can Skip Notice and Comment
Not every agency action runs through the full process. The APA carves out several categories that let an agency act without a proposed rule or public comment period.
- Interpretive rules, which explain how the agency reads an existing statute or regulation and do not carry the force of law.
- General policy statements describing how the agency intends to use its discretionary power.
- Procedural rules governing the agency’s internal organization, procedures, or practices.
- The good cause exception, which lets the agency skip notice and comment when following the standard process would be “impracticable, unnecessary, or contrary to the public interest,” provided the agency explains its reasoning in the rule itself.1Office of the Law Revision Counsel. 5 USC 553 – Rule Making
Courts scrutinize good cause justifications closely, and a weak explanation can get the rule struck down. Two variants build on the exception. Interim final rules take effect immediately upon publication but open a comment period at the same time; agencies use them during emergencies or when delay would cause serious harm. Direct final rules are used for changes the agency expects no one to oppose; if any adverse comment arrives before the effective date, the rule is withdrawn and the agency starts the regular notice-and-comment process.
How the Public Comment Period Works
Once the NPRM is published, anyone can submit written comments: individuals, businesses, trade associations, nonprofits, state and local governments, other federal agencies. The APA requires an opportunity to submit comments but does not set a minimum number of days. Executive Order 12866 directs agencies to allow at least 60 days for significant rules, and 60 days is typical in practice.5Regulations.gov. Learn About the Regulatory Process Complex rules sometimes get 90 days or longer; straightforward changes may get shorter windows.
Comments are submitted through Regulations.gov, which hosts the public docket for each proposed rule and makes every submission part of the public record.6Regulations.gov. Regulations.gov The agency is legally obligated to consider all relevant, timely comments. Some rulemakings also include public hearings, though hearings are not required for standard informal rulemaking.
The Logical Outgrowth Doctrine
The final rule has to be a “logical outgrowth” of what the agency proposed. Courts developed the doctrine to keep agencies from proposing one thing and finalizing something meaningfully different, which would deny the public a real chance to comment on the actual rule. The test is whether the public should have reasonably anticipated that the final version was a possible outcome of the proposal.7U.S. Department of Transportation. Logical Outgrowth Under the Administrative Procedure Act If a final rule is “surprisingly distant” from the NPRM, a court can invalidate it. For anyone commenting, the practical implication is to address not just the specific text the agency proposed but the reasonable alternatives it might adopt.
White House Review of Significant Rules
Under Executive Order 12866, any “significant regulatory action” has to be submitted to the Office of Information and Regulatory Affairs (OIRA) within the Office of Management and Budget before it can move forward. A rule counts as significant if it is likely to have an annual economic effect of $100 million or more, create conflicts with other agency actions, alter the budgetary impact of government programs, or raise novel legal or policy issues.3U.S. Department of Health and Human Services. Executive Order 12866 – Regulatory Planning and Review
For rules that hit the $100 million threshold, the agency has to prepare a detailed regulatory impact analysis quantifying costs and benefits and evaluating less costly alternatives. OIRA has up to 90 days for its review, with the possibility of an extension.8The White House. About OIRA During the review, OIRA can request changes, and outside parties can request meetings to discuss the rule. Review applies to both the proposed rule before the NPRM is published and the final rule before it is published. Rules that don’t meet the significance threshold skip OIRA and move directly to the Federal Register.
The Final Rule and Its Preamble
After the comment period closes, the agency reviews everything it received and decides whether to modify the proposal. If it proceeds, it drafts a final rule with a preamble. The APA calls for a “concise general statement” of the rule’s basis and purpose.1Office of the Law Revision Counsel. 5 USC 553 – Rule Making Concise is not what most preambles are. Agencies use the preamble to walk through the significant comments, explain why they accepted or rejected suggested changes, and lay out the factual and legal foundation for the final regulation. This response-to-comments section matters because courts examine it when deciding whether the agency acted reasonably. Ignoring a significant comment or failing to explain a decision invites a judicial challenge.
Significant rules go back to OIRA for a second round of review at this stage. Once the agency clears all internal and external reviews, the final rule goes to the Federal Register for publication.
When the Rule Takes Effect
Publication does not make a rule immediately enforceable. Substantive rules take effect no earlier than 30 days after publication, giving affected parties time to adjust.1Office of the Law Revision Counsel. 5 USC 553 – Rule Making Three exceptions cut through the 30-day minimum: rules that grant an exemption or relieve a restriction, interpretive rules and policy statements, and situations where the agency finds good cause for an earlier date.
Rules classified as “major” wait longer under the Congressional Review Act (CRA). A rule is major when the OIRA administrator determines it is likely to have an annual economic effect of $100 million or more, significantly increase costs for consumers or industries, or cause substantial adverse effects on competition or employment.9Office of the Law Revision Counsel. 5 USC 804 – Definitions Major rules cannot take effect until at least 60 days after either Congress receives the required report or the rule is published, whichever is later.10Office of the Law Revision Counsel. 5 USC 801 – Congressional Review
Before any rule takes effect, the agency has to submit a report to both chambers of Congress and to the Comptroller General. The report includes a copy of the rule, a statement of whether it qualifies as major, and the proposed effective date. Major rules also require a copy of the cost-benefit analysis and documentation of compliance with the Regulatory Flexibility Act and the Unfunded Mandates Reform Act.10Office of the Law Revision Counsel. 5 USC 801 – Congressional Review Congress can overturn a final rule by passing a joint resolution of disapproval. If the President signs it, the rule is nullified and the agency is barred from reissuing a substantially similar rule unless Congress specifically authorizes it in later legislation.11U.S. Government Accountability Office. FAQs on the Congressional Review Act That “substantially the same” bar is unusually restrictive: a CRA disapproval does not just kill one version of a rule, it blocks the agency from trying the same approach again without new legislation.
Codification in the Code of Federal Regulations
Once a rule takes effect and clears any immediate challenge, it is incorporated into the Code of Federal Regulations (CFR), the official compilation of general and permanent rules issued by executive departments and agencies.12GovInfo. Code of Federal Regulations The CFR is organized into 50 titles by subject and updated annually on a rolling basis. At this point, the rule carries the same binding legal force as the statute that authorized it.
Challenging a Final Rule in Court
Any person adversely affected by a final rule can challenge it through judicial review. The APA authorizes courts to set aside agency actions that are arbitrary or capricious, exceed the agency’s statutory authority, violate constitutional rights, or were adopted without following required procedures.13Office of the Law Revision Counsel. 5 USC 706 – Scope of Review Most challenges live under the arbitrary-and-capricious standard. To survive it, the agency must show that it examined the relevant data, considered important alternatives, and articulated a satisfactory explanation. A rule built on flawed reasoning, ignored evidence, or unexplained departures from past practice is vulnerable.
Timing is strict. Some statutes set short, specific deadlines: the Hobbs Act, for instance, gives challengers 60 days to contest certain agency orders. When no specific statute applies, the default period is six years from publication, though courts have recognized that certain claims based on a rule being applied unlawfully may accrue later. Miss the deadline and the right to challenge the rule is forfeited.
Procedural failures are among the most common grounds for invalidation. If an agency skipped notice and comment without a valid exemption, failed to respond to significant comments in the preamble, or published a final rule that was not a logical outgrowth of its proposal, a reviewing court can vacate the rule and send the agency back to fix its process. The administrative record compiled during rulemaking is what the court reviews, which is why the comment period and the agency’s response to those comments carry so much practical weight for anyone hoping to shape, block, or overturn a federal rule.
