In response to the FY2008 Consolidated Appropriations Act (H.R. 2764; Public Law 110–161), EPA has issued 40 CFR Part 98, which requires reporting of greenhouse gas (GHG) emissions from large sources and suppliers in the United States. Part 98 is intended to collect accurate and timely emissions data to inform future policy decisions.
Under Part 98, suppliers of fossil fuels or industrial GHGs, manufacturers of vehicles and engines, and facilities that emit 25,000 metric tons or more per year of GHG emissions are required to submit annual reports to EPA. Part 98 was published in the Federal Register (www.regulations.gov) on October 30, 2009 under Docket ID No. EPA-HQ-OAR-2008-0508-2278. Part 98 became effective December 29, 2009. This action included reporting requirements for 31 of the 42 emission sources listed in the April 10, 2009 proposed rule.
EPA's GHG reporting system will provide a better understanding of where GHGs are coming from and will guide development of sound policies and programs to reduce emissions. This comprehensive, nationwide emissions data will help in the fight against climate change.
On April 12, 2010, EPA issued four new proposed rules that amend Part 98. These proposals would require reporting of emissions data from oil and natural gas systems, industries that emit fluorinated GHGs, and facilities that inject and store carbon dioxide (CO2) underground for the purposes of geologic sequestration or enhanced oil and gas recovery. In addition, EPA has proposed to add three new reporting requirements to the General Provisions (subpart A). EPA plans to finalize all four of these proposals this year so that they would become effective starting in 2011. More information about these proposed rules.
On May 27, 2010, the Administrator signed a proposed rule that includes technical corrections and clarifying and other amendments to Part 98, which was published on October 30, 2009. In general, the proposed updates would not change the overall requirements of Part 98 but would improve clarity and ensure consistency across the calculation, monitoring and data reporting requirements.
On June 28, 2010, Administrator Jackson signed two actions related to Part 98, which was published on October 30, 2009:
Final Rule: Mandatory Reporting of Greenhouse Gases from Magnesium Production, Underground Coal Mines, Industrial Wastewater Treatment, and Industrial Landfills, finalizes the reporting requirements for these source categories (subparts T, FF, II and TT, respectively). This action also states EPA's final decision not to include ethanol production and food processing as distinct subparts in Part 98, as well as the final decision not to include suppliers of coal in Part 98 at this time. With this final rule the Agency has taken action on all outstanding source categories and subparts from the April 2009 proposal for the GHG reporting program. More information on this rule.
Proposed Confidentiality Determination for the Mandatory Greenhouse Gas Reporting Rule and Proposed Rule Amendment Specifying Procedures for Handling Part 98 Data. This action proposes to determine which data elements to be reported under EPA's GHG Reporting Program would be publicly available and which would be kept confidential. More information on this rule.
On July 20, 2010, EPA signed revisions to certain provisions of the Mandatory Reporting of Greenhouse Gases (GHG) Rule, which was published on October 30, 2009. These proposed amendments primarily make clarifying and technical changes to specific sections of the final rule that were either not clear, or did not have the intended effect. This proposal is complementary to the proposed rulemaking: Technical Corrections, Clarifying and Other Amendments, published on June 15, 2010. Together, these two proposed rulemakings address the most significant questions raised during implementation. More information on this rule.
The U.S. Environmental Protection Agency (EPA) is proposing confidentiality determinations for data reporting requirements included in the July 20, 2010 "Proposed Rulemaking: Revision of Certain Provisions of the Mandatory Reporting of Greenhouse Gases Rule (PDF)" (72 pp, 478K). This action only addresses the confidentiality of the new and revised data elements included in the July 20, 2010 Proposal. More information on this rule.
