Laws & Regulations


EPA is called a regulatory agency because Congress authorizes us to write regulations that explain the technical, operational, and legal details necessary to implement laws. Regulations are mandatory requirements that can apply to individuals, businesses, state or local governments, non-profit institutions, or others. 

We provide a number of tools for you to keep track of and participate in the development of new EPA regulations, and to learn how to comply with existing regulations.

Find regulations

Title 40, Code of Federal Regulations (40 CFR)

Regulations are codified annually in the U.S. Code of Federal Regulations (CFR). Title 40: Protection of Environment is the section of the CFR that deals with EPA's mission of protecting human health and the environment.

The Federal Register

The Federal Register (FR) is the official daily publication for rules, proposed rules, and notices of federal agencies and organizations, as well as executive orders and other presidential documents.

There's a difference between the CFR and the FR. The FR announces ongoing activities of the agencies and notifies you when you can comment on a proposed regulation. Once a final decision is issued in the form of a final regulation, the regulation is then codified when it is incorporated into the CFR.

You may also find more detailed regulatory information regulatory information by topic or by sector.

Track EPA rulemakings and retrospective reviews

EPA rulemakings (i.e., regulations that are under development) could impact you once they become final regulations. But, you have an opportunity to provide input on almost every regulation before it is finalized. To help you get involved in our rulemakings, we provide a number of ways you can keep track of them.

  • Regulatory Development and Retrospective Review Tracker (Reg DaRRT): Access monthly updates on the progress of EPA's priority rulemakings, available from the moment we start working on a rulemaking, and on the progress of EPA's retrospective reviews of existing regulations.
  • Actions Initiated by Month: Read about the rulemakings and other regulatory actions we initiate each month, including some that appear in Reg DaRRT as priority rulemakings and some that don't.
  • Regulatory Agendas and Regulatory Plans: Download twice yearly publications of EPA's regulatory activities.
  • Regulations.gov: This multi-agency website serves as an online clearinghouse for materials related to EPA rulemakings and is EPA's official on-line comment system. Comment on regulations, and access rules that have been published in the Federal Register and related documents.
  • EPA Docket Centers: EPA docket centers provide access to the same information as Regulations.gov for those people without access to the Internet. In addition, the docket centers provide access to those pieces of information that we are unable to provide electronically. You may also submit comments to the docket centers, in addition to submitting them via Regulations.gov.
