Ariz. Admin. Code § 18-2-1426

Current through Register Vol. 30, No. 43, October 25, 2024
Section R18-2-1426 - Criteria and Procedures: Interim Period Reductions for PM[10] and NO[2] Areas (TIP)
A. A TIP shall contribute to emission reductions or shall not increase emissions in PM10 and NO2 nonattainment areas. This criterion applies only during the interim and transitional periods. It applies to the net effect on emissions of all projects contained in a new or revised TIP. This criterion may be satisfied if the requirements of either subsection (B) or subsection (C) are met.
B. Demonstrate that implementation of the plan and TIP and all other regionally significant transportation projects expected in the nonattainment area will contribute to reductions in emissions of PM10 in a PM10 nonattainment area (and transportation-related precursors of PM10 in PM10 nonattainment areas if the EPA Regional Administrator or the Director of ADEQ has made a finding that such precursor emissions from within the nonattainment area are a significant contributor to the PM10 nonattainment problem and has so notified the MPO and USDOT) and of NOx in an NO2 nonattainment area, by performing a regional emissions analysis as follows:
1. Determine the analysis years for which emissions are to be estimated, according to the requirements of R18-2-1425(B)(1).
2. Define for each of the analysis years the Baseline scenario, as defined in R18-2-1423(C), and the Action scenario, as defined in R18-2-1423(D).
3. Estimate the emissions predicted to result in each analysis year from travel on the transportation systems defined by the Baseline and Action scenarios as required by R18-2-1425(B)(3), and make the demonstration required by R18-2-1425(B)(4).
C. Demonstrate that when the projects in the transportation plan and TIP and all other regionally significant transportation projects expected in the area are implemented, the transportation system's total highway and transit emissions of PM10 in a PM10 nonattainment area (and transportation-related precursors of PM10 in PM10 nonattainment areas if the EPA Regional Administrator or the Director of ADEQ has made a finding that such precursor emissions from within the nonattainment area are a significant contributor to the PM10 nonattainment problem and has so notified the MPO and USDOT) and of NOx in an NO2 nonattainment area will not be greater than baseline levels, by performing a regional emissions analysis as required by R18-2-1425(C).
