40 CFR Part 98, Subpart C - General Stationary Fuel Combustion Sources

The Environmental Protection Agency (EPA) is adding chemical-specific and default global warming potentials (GWPs) for a number of fluorinated greenhouse gases (F-GHGs) and fluorinated heat transfer fluids (F-HTFs) to the general provisions of the Greenhouse Gas Reporting Rule. Currently, these fluorinated GHGs and HTFs are not assigned GWPs under the rule. The changes will increase the completeness and accuracy of the carbon dioxide (CO 2 )-equivalent emissions calculated and reported by suppliers and emitters of fluorinated GHGs and HTFs. The EPA is also making conforming changes to the provisions for the Electronics Manufacturing and Fluorinated Gas Production source categories. In addition, the EPA is amending certain provisions of the Fluorinated Gas Production source category to reduce the level of detail in which emissions are reported, eliminate the mass-balance emission calculation method, and clarify the emission factor method. These amendments also include an alternative verification approach for this source category in lieu of collecting certain data elements for which the EPA has identified disclosure concerns and for which the reporting deadline was deferred until March 31, 2015. In addition, this action establishes confidentiality determinations for certain reporting requirements of the Fluorinated Gas Production source category.

The Environmental Protection Agency (EPA) is finalizing revisions and confidentiality determinations for the petroleum and natural gas systems source category and the general provisions of the Greenhouse Gas Reporting Rule. These revisions include changes to certain calculation methods, amendments to certain monitoring and data reporting requirements, clarification of certain terms and definitions, and corrections to certain technical and editorial errors that have been identified during the course of implementation. This action also finalizes confidentiality determinations for new or substantially revised data elements contained in these amendments and revises the confidentiality determination for one existing data element.

The Environmental Protection Agency (EPA) is correcting a final rule that appeared in the Federal Register on December 11, 2014 (79 FR 73750). The final rule amends the general provisions of the Greenhouse Gas Reporting Rule to establish chemical-specific and default global warming potentials (GWPs) for a number of fluorinated greenhouse gases (F-GHGs) and fluorinated heat transfer fluids (F-HTFs). The rule also includes conforming changes to the provisions for the Electronics Manufacturing and Fluorinated Gas Production source categories.

The Environmental Protection Agency (EPA) is announcing a change in date for the public hearing for the proposed rule titled “Greenhouse Gas Reporting Program: 2015 Revision and Confidentiality Determinations for Petroleum and Natural Gas Systems”. The original public hearing date was December 24, 2014, and the new public hearing date will be January 8, 2015.

The Environmental Protection Agency (EPA) is proposing revisions and confidentiality determinations for the petroleum and natural gas systems source category of the Greenhouse Gas Reporting Program. In particular, the EPA is proposing to add calculation methods and reporting requirements for greenhouse gas emissions from gathering and boosting facilities, completions and workovers of oil wells with hydraulic fracturing, and blowdowns of natural gas transmission pipelines between compressor stations. The EPA is also proposing well identification reporting requirements to improve the EPA's ability to verify reported data and enhance transparency. This action also proposes confidentiality determinations for new data elements contained in these proposed amendments.
