Subpart UU – Injection of Carbon Dioxide
This page provides resources for subpart UU reporters, including implementation information as well as supporting documents for relevant rulemakings.
On this page:
Summary
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.
Visit the Capture, Supply, and Underground Injection of Carbon Dioxide page for more information about this sector.
