Rule Information

Latest Developments

November 25, 2014
The Administrator signed a final rule that adds 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. The changes will increase the completeness and accuracy of the carbon dioxide (CO2)-equivalent emissions calculated and reported by suppliers and emitters of fluorinated GHGs and HTFs. This final action also makes conforming changes to the provisions for the Electronics Manufacturing and Fluorinated Gas Production source categories. In addition, the final rule amends 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. More information »

  • For package delivery (Preferred): Carole Cook, c/o Director, Climate Change Division, U.S. Environmental Protection Agency, 1310 L Street, NW, 802e, Washington, DC 20005. Phone: 202-343-9263
  • For U.S. mail: Carole Cook, c/o Director, Climate Change Division, U.S. Environmental Protection Agency, 1200 Pennsylvania Avenue, NW, Mail Code: 6207J, Washington, DC 20460

BAMM requests for subpart W must be submitted through e-GGRT.
