You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.

This rule requires reporting of greenhouse gases (GHGs) from facilities that inject carbon dioxide underground for the purposes of enhanced oil and gas recovery or any other purpose other than geologic sequestration. Facilities that report under subpart RR for a well or group of wells are not required to report under subpart UU for that well or group of wells.
