Advance Notice of Proposed Rulemaking: ANPRM Guide

The short version

An advance notice of proposed rulemaking, often shortened to ANPRM, is an early Federal Register document that asks for information before an agency settles on a proposed rule.

Agencies use ANPRMs to gather facts, test possible approaches, ask focused questions, and learn how a problem affects regulated parties and the public. An ANPRM may or may not include possible regulatory text. The key point is that the agency is still shaping the record before it publishes a notice of proposed rulemaking, if it decides to move forward.

An ANPRM matters because it can be one of the first useful chances to influence the rulemaking record. A comment with facts, examples, cost information, technical constraints, or better alternatives can help the agency understand the issue before a proposal is locked in.

How an ANPRM fits in rulemaking

Federal rulemaking uses several document types, and they do different jobs.

• ANPRM: An early request for information or views. It usually does not create new legal duties by itself, and it normally comes before any proposed rule text is final enough for a proposal.
• Proposed rule: Also called a notice of proposed rulemaking or NPRM. It announces the agency's proposed action and opens a comment period on that proposal. Proposed rules often include proposed CFR amendments or enough detail for the public to respond.
• Final rule: The adopted rule. A final rule usually states its effective date and, when it changes general and permanent requirements, amends the Code of Federal Regulations.
• Notice: An official Federal Register announcement that may cover meetings, information collections, comment-period extensions, hearings, permits, or other agency actions. A notice is not automatically a rule.
• CFR: The Code of Federal Regulations is where general and permanent federal rules are organized after adoption. An ANPRM is earlier than codification.

Not every rulemaking starts with an ANPRM. Many agencies move straight to a proposed rule when they already have enough information. Others use an ANPRM when the subject is complex, the record is thin, or the agency wants public input before choosing a regulatory path. The agency's power to regulate still comes from statutes and other law, not from the ANPRM itself.

What to check first

The most important parts of an ANPRM are the dates, the questions, and the docket information.

Start with the DATES section in the Federal Register document. It tells you whether comments are being accepted and when they are due. Comment periods vary by agency, statute, document type, and subject, so do not rely on a default number of days. If the deadline changes, the agency often publishes a separate Federal Register notice extending or reopening the comment period.

Then read the agency's questions. ANPRMs often ask for facts the agency does not yet have, such as market data, technical limits, compliance costs, safety issues, small-business effects, state or local impacts, or alternatives to regulation. A strong comment answers the questions directly, names the source of the information, and explains the real-world effect.

Finally, use the docket number to find supporting materials and submitted comments on Regulations.gov, unless the Federal Register document gives a different submission method. For the official publication text, use FederalRegister.gov. If the issue affects your work, set up a free watch on RegWatch so you see matching ANPRMs, proposed rules, notices, and comment deadlines without checking by hand.

How to comment on an ANPRM

An ANPRM comment is most useful when it gives the agency information it can use later in the rulemaking record.

• Answer the agency's numbered questions before adding broader concerns.
• Explain how the issue works in practice, especially facts the agency may not see from public data.
• Separate impacts on large firms, small firms, nonprofits, state agencies, consumers, or other affected groups when those differences matter.
• Identify clearer or lower-cost alternatives that still fit the agency's legal goal.
• Flag definitions, thresholds, reporting systems, or implementation timelines that could create avoidable problems.
• Ask for another comment opportunity if the agency later publishes a proposed rule.

The agency may decide not to regulate, may publish a proposed rule, may issue another notice, or may take another path allowed by law. An ANPRM does not guarantee a final rule and does not mean the final policy has already been chosen. It means the agency is asking for public input while the rulemaking record is still being built.
