The Triangle West TPO will be adopting the updated Triangle Region Transportation Air Quality Conformity Determination Report (AQ CDR) on August 26, 2025. This update was required because the TPO will be adopting the FY 2026-2035 TIP (Transportation Improvement Program).

The Air Quality Conformity Determination Report (AQ-CDR) demonstrates that certain pollutant emissions from the future transportation sector will not exceed a specified threshold. Although the Triangle area is in attainment for all of the controlled emissions, the area is in a maintenance program for ozone and therefore must demonstrate conformity for nitrous oxides, which help create ozone. The updated AQ CDR demonstrates that the implementation of the 2050 MTP will result in a level of pollutant emissions that meet the air quality thresholds.
The public comment period will be open until July 23. Comments can be provided via this survey.
