Abstract
EPA is taking direct final action approving a State Implementation Plan (SIP) revision submitted by the State of Colorado. On March 31, 2010, the Governor of Colorado's designee submitted to EPA a Clean Air Act (CAA) section 175A(b) second 10-year maintenance plan for the Colorado Springs area for the carbon monoxide (CO) National Ambient Air Quality Standard (NAAQS). This limited maintenance plan (LMP) addresses maintenance of the CO NAAQS for a second 10-year period beyond the original redesignation. This action is being taken under sections 110 and 175A of the CAA.
