Get Involved with EPA Regulations

Many people get involved with EPA's regulations by submitting comments when we publish a proposed version in the Federal Register. You can submit comments on-line at or you can make a submission via mail, e-mail, or EPA docket centers.

Often, you can get involved well before a proposed regulation is published, as well. And after a regulation is finalized, regulated entities (such as businesses, state governments, or individuals) can stay involved by learning how to comply. Learn how to:

Keep tabs on rulemakings

  • Regulatory Development and Retrospective Review Tracker (Reg DaRRT) - View monthly (and in some cases daily) updates to our priority rulemakings that are under development as well as our retrospective reviews of existing regulations. Reg DaRRT posts a profile on a priority rulemaking right when we start to work on it, which is sometimes months or even years before we publish a proposed rule. Also, Reg DaRRT offers a number of RSS feeds and lists upcoming public meetings related to priority rulemakings. 
  • Actions Initiated by Month - Every month, we post an Action Initiation List (AIL) that includes every new rulemaking that we are initiating. If there's a priority rulemaking on the AIL, we link to Reg DaRRT so you can continually keep tabs on it. If a rule isn't on Reg DaRRT, you can still get twice yearly updates in our Regulatory Agenda .
  • - This is EPA's official on-line commenting system. Any rule in Reg DaRRT that is open for comment directs you to so you may submit a comment. Also, from, you can sign up for email alerts and sign up for RSS feeds.
