How Federal Agencies Make Regulations

Congress passes statutes that can direct an agency to carry out a program or give it authority to set more detailed requirements. A regulation, also called a rule, is one way an agency does that. An agency must act within the authority Congress gave it; the notice-and-comment process does not itself grant new authority. The statute and any other laws that apply to the subject help determine what procedures the agency must follow. ([uscode.house.gov](https://uscode.house.gov/view.xhtml?edition=prelim&f=treesort&num=0&req=%28title%3A5+section%3A553+edition%3Aprelim%29+OR+%28granuleid%3AUSC-prelim-title5-section553%29&utm_source=openai))

The usual process described here is the Administrative Procedure Act’s (APA) informal notice-and-comment rulemaking procedure. It is a useful general guide, not a guarantee that every agency action follows the same steps. A law may set additional requirements, deadlines, or procedures for a particular agency or subject.

A typical sequence is: the agency develops a proposal, publishes a notice of proposed rulemaking, accepts comments, considers the relevant material, and publishes a final rule if it decides to proceed. The process may take months or longer, and it can change along the way. An agency might extend a comment period, publish a revised proposal, withdraw a proposal, or take a different procedural route when the governing law allows it.

Under 5 U.S.C. § 553, a notice of proposed rulemaking generally identifies the legal authority for the proposal and describes its terms or the subjects and issues involved. It must provide an opportunity for interested people to submit written data, views, or arguments; an oral presentation may also be offered. The statute does not set one standard comment-period length for every rule. Check the notice itself for the deadline and instructions. ([uscode.house.gov](https://uscode.house.gov/view.xhtml?edition=prelim&f=treesort&num=0&req=%28title%3A5+section%3A553+edition%3Aprelim%29+OR+%28granuleid%3AUSC-prelim-title5-section553%29&utm_source=openai))

Comments are a way to put relevant information, reasoning, and alternatives into the rulemaking record. A comment can support or oppose the proposal, identify a practical problem, offer evidence, or suggest different wording. The APA says agencies must consider relevant matter presented and include a concise general statement of a final rule’s basis and purpose. A final rule’s explanation is where readers can look for the agency’s discussion of significant issues and changes made after comments. ([uscode.house.gov](https://uscode.house.gov/view.xhtml?edition=prelim&f=treesort&num=0&req=%28title%3A5+section%3A553+edition%3Aprelim%29+OR+%28granuleid%3AUSC-prelim-title5-section553%29&utm_source=openai))

Notice and comment is common, but it is not universal. Section 553 excludes certain matters from its requirements, including some military or foreign-affairs functions and matters involving agency management or personnel. It also generally exempts interpretative rules, general policy statements, and rules about agency organization, procedure, or practice—unless another statute requires notice or a hearing. Agencies may also invoke the APA’s “good cause” exception when they find that notice and public procedure are impracticable, unnecessary, or contrary to the public interest; the statute calls for the agency to state its reasons in the rule. Other statutes can impose separate or additional requirements. ([uscode.house.gov](https://uscode.house.gov/view.xhtml?edition=prelim&f=treesort&num=0&req=%28title%3A5+section%3A553+edition%3Aprelim%29+OR+%28granuleid%3AUSC-prelim-title5-section553%29&utm_source=openai))

Some rulemaking documents are labeled “interim final rule” or “direct final rule,” rather than following the familiar proposal-then-final sequence. The label alone does not tell you the legal basis or what happens next. Read the document’s explanation, comment instructions, and cited authority to see whether comments are invited, whether the rule has an effective date, and whether the agency describes any next steps. ([archives.gov](https://www.archives.gov/federal-register/tutorial/text?utm_source=openai))

Start with the Federal Register, the federal government’s daily journal for rules, proposed rules, notices, and presidential documents. Search by topic, agency, phrase, or a known document number. In a document, check the agency and action labels first: “Proposed Rule” generally signals a proposal, while “Rule” or “Final Rule” signals a final action. The document’s summary and supplementary information explain what the agency is proposing or deciding. ([archives.gov](https://www.archives.gov/federal-register/the-federal-register/about.html?utm_source=openai))

For a proposal, look for the “DATES” and “ADDRESSES” sections. They typically identify the comment deadline and how to submit input. Also note the docket number, which links the Federal Register notice to the agency’s rulemaking record. Regulations.gov is used for comments and dockets for many federal rulemakings, but the issuing agency’s instructions control. The Office of the Federal Register publishes documents; it does not itself receive or manage agency comments. ([archives.gov](https://www.archives.gov/federal-register/tutorial/text?utm_source=openai))

Search Regulations.gov by the docket number to find the associated docket and, where available, supporting documents and posted comments. A docket can contain more than the Federal Register notice, such as agency materials or later documents in the proceeding. If the Federal Register page does not link to a Regulations.gov comment form, follow the submission method stated in the notice or contact the agency listed under “FOR FURTHER INFORMATION CONTACT.” ([regulations.gov](https://www.regulations.gov/assets/files/Public-Comment-on-Federal-Regulations_Final.pdf?utm_source=openai))

To see what changed, compare the proposed rule with the final rule. Read the final document’s explanation of comments and its regulatory text, not just the headline or short summary. A final rule may adopt the proposal, revise parts of it, or take another action described by the agency. Then check the Code of Federal Regulations (CFR) for how regulations are organized by subject and agency. The eCFR is a convenient, continuously updated online version, but it identifies itself as authoritative yet unofficial; the CFR is the official legal edition. ([archives.gov](https://www.archives.gov/federal-register/the-federal-register/about.html?utm_source=openai))

A final rule’s publication date and effective date are not necessarily the same. Under the APA, substantive rules generally must be published or served at least 30 days before taking effect, subject to statutory exceptions and exceptions stated in the law. The final rule’s “DATES” section is the place to check the agency’s stated effective date. Some rules also set separate compliance dates or phase in requirements, so note which date applies to the question you are asking. ([uscode.house.gov](https://uscode.house.gov/view.xhtml?edition=prelim&f=treesort&num=0&req=%28title%3A5+section%3A553+edition%3Aprelim%29+OR+%28granuleid%3AUSC-prelim-title5-section553%29&utm_source=openai))

A published rule is not automatically immune from legal challenge or later agency action. The APA provides for judicial review in certain circumstances, including review of whether agency action exceeds its authority or fails to observe legally required procedure. For a rule with major practical or legal consequences, check for later Federal Register documents, updates to the codified text, and relevant court orders rather than treating the original publication as the final word on its status or effects. ([uscode.house.gov](https://uscode.house.gov/view.xhtml?edition=prelim&num=0&req=granuleid%3AUSC-prelim-title5-section706&utm_source=openai))

When tracking a rule, keep the proposal, docket, final action, and dates together. This helps distinguish what the agency proposed from what it ultimately adopted and what is currently scheduled to apply.
