(b) On June 25, 1996, the Governor of Colorado submitted a revision to the Colorado Springs element of the carbon monoxide (CO) portion of the Colorado State Implementation Plan (SIP). The revision to the Colorado Springs element was submitted to satisfy certain requirements of part D and section 110 of the Clean Air Act (CAA) as amended 1990. The revision substitutes Colorado's oxygenated gasoline program for the Colorado Springs bus purchase program as a source of emissions reductions credits in the Colorado Springs CO element of the SIP.
