The word "comment" has specific connotations for rule writers. Before EPA finalizes a rule, we typically publish a draft version – called a Notice of Proposed Rulemaking (NPRM) – in the Federal Register and invite the public to provide written feedback during a "formal comment period" specified in the NPRM's preamble. Generally, the Administrative Procedure Act of 1946 (APA) requires EPA to consider every germane comment received during a formal comment period.
All formal comments, the NPRM, the finalized rule, supporting documentation, and other information on EPA rulemakings are stored in a docket (i.e., an electronic folder) on Regulations.gov. If you want to submit a formal comment on an NPRM that is open for comment, please go to Regulations.gov. Feedback submitted through the Rulemaking Gateway website is not considered a formal comment, and EPA is not obligated under section 553 of the APA to address your data, views, or arguments.
