Greenhouse Gas Reporting Program

Subpart RR – Geologic Sequestration of Carbon Dioxide

You will need Adobe Reader to view some of the files on this page. See EPA’s PDF page to learn more.

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.

Latest Developments

March 1, 2013
EPA proposed amendments to the Greenhouse Gas Reporting Program (GHGRP) that affect this subpart. The amendments consist of three parts: Minor Technical Amendments, Amendments Related to Global Warming Potentials (GWPs), and Confidentiality Determinations for new or revised data elements.

December 17, 2012
EPA has evaluated (PDF) (34 pp, 297K) inputs whose reporting deadline was deferred until 2013 following the process that was outlined in the final inputs deferral rule[1], and does not plan to take further action regarding the 2013 inputs. Therefore, inputs to equations whose reporting was deferred until 2013 must be reported to EPA by April 1, 2013[2], for reporting years 2010, 2011, and 2012 as applicable[3]. The 2013 inputs will be reported as part of the RY 2012 reporting process. More info (PDF) » 3 pp, 48K)

[1] 76 FR 53057 published 8/25/11, p.53061
[2] Because March 31, 2013 falls on a weekend, the deadline is moved to the next business day which is April 1, 2013.
[3] Facilities should have this information for prior years because inputs to equations are required to be kept as recordkeeping (see 40 CFR Part 98.3).

  • Proposed Monitoring, Reporting, and Verification (MRV) plan (or extension request) or Research and Development (R&D) project exemption request is due by June 30, 2011

If you are subject to Subpart RR and were issued a final UIC permit (any class) on or after January 1, 2011:

  • Certificate of Representation is due 60 days prior to submission of a proposed MRV plan (or extension request) or R&D exemption request
  • Proposed MRV plan (or extension request) or R&D project exemption request is due within 180 days of receiving your final UIC permit

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).
