Rule Information

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.

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)

[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).
