Pikes Peak Area Council of Governments 15 S. 7th Street, Colorado Springs, CO 80905
Subject: Greenhouse Gas Transportation Report as required by the Colorado Greenhouse Gas Pollution Reduction Planning Rule
Per 2 CCR 601-22, Rules Governing Statewide Transportation Planning Process and Transportation Planning Regions, the Colorado Department of Public Health and Environment (CDPHE), Air Pollution Control Division (Division), is respectfully submitting our verification of the Transportation Greenhouse Gas Report associated with the 2050 Regional Transportation Plan 2024 Amendment.
Thank you for the opportunity for CDPHE to review and verify the Pikes Peak Area Council of Governments Transportation Greenhouse Gas Report for the Pikes Peak Area MPO.
Based on the analysis of the report, supporting datasets, and information provided, we can verify that the report and data inputs address the requirements of the Colorado Greenhouse Gas Pollution Reduction Planning Rule. The submitted package describes the baseline and compliance transportation demand modeling (TDM) runs and how they meet the Rule requirements. The submitted package describes how the TDM model was deployed and how emissions were calculated. The Report includes a summary table of the MOVES database outputs for each base and action analysis year. The Division finds the outputs to be mathematically correct.
The Division would like to thank the Pikes Peak Area Council of Governments for providing the necessary data files and Report. The Division would also like to thank Dale Wells from the Division who performed the verification analysis and Sabrina Williams and Scott Ramming of CDOT for their efforts in validating the results.
Sincerely,
