Our proposed regulations are almost always open to the public for comment, typically for 30-90 days after the date of publication in the Federal Register. You can comment on them in several ways; each rule tells you how in its "Addresses" section. You can also learn more about commenting on our "Get Involved with EPA Regulations" page.
- Headquarters offices
- Regional offices (click on the Region you are located in)
- Labs and research centers
Once there, look for the "Contact" link in the Related Information box (NOT the "Contact Us" link in the upper right corner of the page -- clicking on that will bring you back to this page).

We strive to respond to every request with an answer or an appropriate referral as quickly as possible. Most websites within epa.gov have their own "Contact Us" pages. Almost every page on epa.gov has links at the upper right and at the bottom that go to the "Contact Us" page for that topic. You will receive a quicker response if you send your question or comment to the "Contact Us" page that is most closely related to the topic you're interested in.
