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 Greeley 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.
