The Colorado Department of Public Health and Environment has amended several regulations contained within Regulation Number 3, Parts A, B, C, and D. The Air Quality Control Commission has proposed revisions to primarily address federal changes to the New Source Review (NSR) Program related to PM2.5 National Ambient Air Quality Standards (NAAQS); these proposed revisions are seen as necessary for consistent state implementation of the federal NSR program.
In addition, the Division is proposing revisions that address several recent Environmental Protection Agency (EPA) State Implementation Plan (SIP) actions in which the EPA partially disapproved various SIP revisions. The Division is also proposing to incorporate into Colorado’s Prevention of Significant Deterioration (PSD) and Title V Permitting Programs the EPA’s Deferral of Biogenic Sources of CO2 Emissions to ensure consistent state implementation of greenhouse gas regulation under the federal PSD and Title V Permitting Programs.
Finally, the Division is proposing to make other miscellaneous revisions and to correct typographical, grammatical, and formatting errors.
A hearing on the amended regulations will be held on Thursday, October 20, 2011 at the Colorado Department of Public Health and Environment, 4300 Cherry Creek Drive South, Sabin Conference Room, Denver, Colorado 80246, beginning at 9:00 am.
