Abstract
EPA is approving the State Implementation Plan (SIP) revisions submitted by the Governor of Colorado on July 18, 1995 and April 22, 1996. The PM10 and NO<INF>X</INF> emissions budgets contained in these SIP revisions are used to assess the conformity of transportation plans, transportation improvement programs and, where appropriate, federally funded projects for the applicable periods required by EPA's conformity rules. EPA originally proposed approval of the two emissions budget SIPs on October 3, 1996. Based upon comments received on that proposal, EPA published a second proposal on August 5, 1997, seeking additional input on certain issues. In reaching its final decision to approve the July 18, 1995 and April 22, 1996 PM10 and NO<INF>X</INF> SIP submittals, EPA has considered the comments it received on both its October 3, 1996 and August 5, 1997 Federal Register documents.
