On April 24, 2019, the commission adopted the El Paso Redesignation Request and Maintenance Plan SIP Revision for the One-Hour Ozone NAAQS (Non-Rule Project No. 2018-029-SIP-NR). The SIP revision includes a request that the United States Environmental Protection Agency (EPA) redesignate the El Paso area (El Paso County) to attainment for the one-hour ozone NAAQS and provides a maintenance plan that will ensure the area remains in attainment of the NAAQS through 2032. The SIP revision includes a request that the EPA also consider this plan as a second 10-year maintenance plan for the one-hour ozone NAAQS.
