Sources including, but not limited to, large combustion sources, landfills, oil & gas facilities, power plants, ethanol plants, large breweries, refineries, fertilizer manufacturers, and industrial facilities or mining operations utilizing perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), or sulfur hexafluoride (SF6) in their processes may be subject to the Prevention of Significant Deterioration and Title V permitting programs.
Most stationary sources in Colorado are not anticipated to have the potential to emit greater than 100,000 tpy CO2e. Please note, however, that exemption from the Environmental Protection Agency's (EPA) Mandatory Reporting Rule does not guarantee exemption from the Prevention of Significant Deterioration (PSD) and Title V permitting requirements.
Colorado sources with emissions of biogenic GHG can defer the inclusion of biogenic CO2 in GHG emission calculations for Title V and PSD applicability, in accordance with EPA’s “Deferral for CO2 Emissions from Bioenergy and Other Biogenic Sources” (76FR43490, July 20, 2011). Note that this deferral applies ONLY to CO2 emissions from biogenic sources; CH4 and other GHG emissions from biogenic sources must still be included in applicability calculations. This deferral will expire on July 21, 2014, absent additional action by EPA and the AQCC. Please contact the Division for additional information on the permitting requirements for your source.
