Subpart RR – Geologic Sequestration of Carbon Dioxide

Rule Information

This rule requires reporting of greenhouse gases (GHGs) from facilities that inject carbon dioxide underground for geologic sequestration. Geologic sequestration (GS) is the long-term containment of carbon dioxide in subsurface geologic formations.

This rule is complementary to and builds on EPA's Federal Requirements under the Underground Injection Control (UIC) Program for Carbon Dioxide Geologic Sequestration Wells.

Subpart RR Final Decisions

Under subpart RR, EPA must approve all geologic sequestration monitoring, reporting, and verification (MRV) plans, requests for a research and development exemption, and requests to discontinue reporting. Any interested person can formally appeal any of these decisions. More Information (PDF) (2 pp, 37K).

Posted below are final decisions under 40 CFR Part 98, Subpart RR. If you have questions or would like a copy of any available actual, signed and dated final decision, please send an email to gsreporting@epa.gov or contact the Help Center.
