Abstract
EPA is approving revisions to the Colorado and Montana State Implementation Plans (SIPs) that incorporate consultation procedures for transportation conformity. The conformity rules assure that in air quality nonattainment or maintenance areas, projected emissions from transportation plans and projects stay within the motor vehicle emissions ceiling in the SIP. The transportation conformity SIP revisions enable the States to implement and enforce conformity consultation procedures in regulations for Conformity to State or Federal Implementation Plans of Transportation Plans, Programs, and Projects Developed, Funded or Approved Under Title 23 U.S.C. or the Federal Transit Laws. We are approving these SIP revisions under sections 110(k) and 176 of the Clean Air Act (Act).
