Ariz. Admin. Code § R18-2-1424 - Criteria and Procedures: Interim Period Reductions for Ozone and CO Areas (Project Not from a Plan and TIP)
A transportation project shall contribute to emissions reductions in ozone and CO nonattainment areas. This criterion applies during the interim and transitional periods only, except as otherwise provided in R18-2-1436 . This criterion is satisfied if a regional emissions analysis is performed which meets the requirements of R18-2-1422 and which includes the transportation plan and project in the Action scenario. If the project which is not from a conforming transportation plan and TIP is a modification of a project currently in the plan or TIP, the Baseline scenario shall include the project with its original design concept and scope, and the Action scenario shall include the project with its new design concept and scope.
