Reopening a Federal Register Comment Period

The short version

A reopened comment period means a federal agency has opened another window for public comments on the action identified in a Federal Register document.

The action may be a proposed rule, a notice, a request for information, an information collection notice, or another agency document that asks for public input. If the document says the comment period is reopened, comments can be submitted if the new period is still open and the document invites public comments. Use the deadline in the DATES section and follow the submission instructions in ADDRESSES and any related instructions in SUPPLEMENTARY INFORMATION.

A reopening does not by itself change a proposal, create a final rule, delay an effective date, or amend the Code of Federal Regulations. It means the agency is adding or restoring time for comments on the document, issue, or docket it names. The safest sources are the published document on FederalRegister.gov and the matching docket or comment page on Regulations.gov when the agency uses that portal.

Why agencies reopen comment periods

Agencies reopen comment periods when they decide more public input is useful or required after an earlier comment window has closed or needs to be restored.

Common reasons include public requests for more time, newly available data, a public hearing, a correction, a technical problem receiving comments, a court remand, or a related proposal that changes what commenters need to evaluate. The reopening document should identify the earlier Federal Register publication or citation, the docket ID if there is one, the new close date, and any limits on the subjects the agency wants comments about.

Read the scope carefully. Some reopenings invite comments on the whole proposal or notice. Others ask only about new material, a specific issue, or a changed deadline. A comment outside that stated scope may appear in a docket, but the agency may say it is outside the request being considered. Do not assume the agency will consider late comments after the reopened deadline unless the document says so.

Can you file a new comment?

Yes, if the reopened period is open and the Federal Register document invites comments from the public.

• Open the Federal Register document and read the DATES section for the new deadline.
• Read ADDRESSES for the allowed submission methods. Many agencies use Regulations.gov, but some provide different or additional methods.
• Search the docket ID on Regulations.gov if one is listed, then confirm that the docket or document is open for comments.
• Check whether the agency limits comments to certain issues, documents, or questions.
• Include the docket ID, RIN, file number, or other identifier the agency asks commenters to use.

Comments filed during the original period usually remain in the public docket or rulemaking record. You usually do not need to resubmit the same comment unless the agency asks for resubmission, says there was a receiving or docket problem, or the record shows your comment was not received. If you have new evidence, changed facts, or a clearer explanation, submit it before the reopened deadline.

How it differs from related actions

A reopened comment period is not the same thing as a proposed rule, final rule, correction, withdrawal, or effective-date delay.

A proposed rule is the agency's proposal and normally invites public comment before the agency decides whether and how to finalize it. The Administrative Procedure Act generally requires agencies to give interested persons an opportunity to participate in notice-and-comment rulemaking, but exceptions and special statutes exist. A final rule is the agency's adopted rule and usually includes an effective date. Final rules that amend general and permanent rules are later reflected in the Code of Federal Regulations. A notice may request information, announce a hearing, manage an information collection, or handle a docket without changing the CFR by itself.

That distinction matters because the right response depends on the document type. If an agency reopens comments on a proposed rule, comments may still influence what becomes final. If an agency reopens comments after a final rule, direct final rule, interim final rule, or court remand, read the document closely to see exactly what the agency is reconsidering and whether any effective date, compliance date, or CFR text is affected.

How to track reopenings

Reopenings are easy to miss because they may publish days, weeks, or months after the original Federal Register document.

Search FederalRegister.gov by docket ID, agency, Regulation Identifier Number, Federal Register citation, or the title of the original document. Then check Regulations.gov or the agency's listed comment system for docket status, supporting materials, and the live comment form. FederalRegister.gov may show enhanced fields such as Comments Close, but the published DATES text and agency instructions are the source to read first.
