An official website of the United States government.

Due to a lapse in appropriations, EPA websites will not be regularly updated. In the event of an environmental emergency imminently threatening the safety of human life or where necessary to protect certain property, the EPA website will be updated with appropriate information. Please note that all information on the EPA website may not be up to date, and transactions and inquiries submitted to the EPA website may not be processed or responded to until appropriations are enacted.

We've made some changes to EPA.gov. If the information you are looking for is not here, you may be able to find it on the EPA Web Archive or the January 19, 2017 Web Snapshot.

Questions about EPA Organizations

If you have a question about an EPA headquarters office or about one of our Regional offices around the nation, please:
  • go to that office's page (you'll find the links in the middle of the About EPA home page).
  • 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).​

Local or Regional Issues

If you have a question about a local or regional issue, please:
  • view the map of EPA Regions; click on the Region you are located in
  • 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).

Questions about Other Topics

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. 

If you have a question about a topic not mentioned on this page, try the "Contact Us" page that is most closely related to the topic you're interested in, or the main Contact EPA page.
