EPA Greenhouse Gas Permitting Requirements Maintain Focus on Largest Emitters/Steps to streamline process will ease burden on state and local permitting authorities

WASHINGTON – July 03, 2012 - The U.S. Environmental Protection Agency (EPA) today announced that it will not revise greenhouse gas (GHG) permitting thresholds under the Clean Air Act. Today’s final rule is part of EPA’s common-sense, phased-in approach to GHG permitting under the Clean Air Act, announced in 2010 and recently upheld by the U.S. Court of Appeals for the D.C. Circuit. The final rule maintains a focus on the nation’s largest emitters that account for nearly 70 percent of the total GHG pollution from stationary sources, while shielding smaller emitters from permitting requirements. EPA is also finalizing a provision that allows companies to set plant-wide emissions limits for GHGs, streamlining the permitting process, increasing flexibilities and reducing permitting burdens on state and local authorities and large industrial emitters.

After consulting with the states and evaluating the phase-in process, EPA believes that current conditions do not suggest that EPA should lower the permitting thresholds. Therefore, EPA will not include additional, smaller sources in the permitting program at this time.

Today’s final rule affirms that new facilities with GHG emissions of at least 100,000 tons per year (tpy) carbon dioxide equivalent (CO2e) will continue to be required to obtain Prevention of Significant Deterioration (PSD) permits. Existing facilities that emit 100,000 tpy of CO2e and make changes increasing the GHG emissions by at least 75,000 tpy of CO2e, must also obtain PSD permits. Facilities that must obtain a PSD permit, to include other regulated pollutants, must also address GHG emission increases of 75,000 tpy or more of CO2e. New and existing sources with GHG emissions above 100,000 tpy CO2e must also obtain operating permits.

EPA’s GHG permitting program follows the same Clean Air Act process that states and industry have followed for decades to help ensure that new or modified facilities are meeting requirements to protect air quality and public health from harmful pollutants. As of May 21, 2012, EPA and state permitting authorities have issued 44 PSD permits addressing GHG emissions. These permits have required new facilities, and existing facilities that make major modifications, to implement energy efficiency measures to reduce their GHG emissions.

The GHG Tailoring Rule will continue to address a group of six greenhouse gases: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). The PSD permitting program protects air quality and allows economic growth by requiring facilities that trigger PSD to limit GHG emissions in a cost effective way. An operating permit lists all of a facility’s Clean Air Act emissions control requirements and ensures adequate monitoring, recordkeeping and reporting. The operating permit program allows an opportunity for public involvement and to improve compliance.
