New Executive Director's Recommended CO Limited Maintenance Plan SIP Revision for El Paso

On September 7, 2016, the commission will consider adoption of the El Paso CO Limited Maintenance Plan SIP Revision (Non-Rule Project No. 2015-015-SIP-NR). The SIP revision would satisfy Section 175A(b) of the Federal Clean Air Act, which requires states to submit an additional revision to the SIP eight years after the redesignation of any area to attainment. The second maintenance plan must demonstrate continued attainment of the standard for 10 years after the expiration of the initial maintenance period. This SIP revision would demonstrate continued maintenance of the CO National Ambient Air Quality Standard in El Paso for the period of October 2018 through October 2028.
