The BGMPO adopted the updated Triangle Region Transportation Air Quality Conformity Determination Report (AQCDR) on August 19, 2025. This update was required because the MPO amended the 2050 Metropolitan Transportation Plan and adopted the 2024-2033 Metropolitan Transportation Improvement Program (TIP). The 2026-2035 TIP will reflect the amendments (if any) and will be uploaded when adopted.
The Air Quality Conformity Determination Report (AQCDR) demonstrates that certain pollutant emissions from the future transportation sector will not exceed a specified threshold. Although the portion of the BGMPO's Metropolitan Planning Area that extends into Orange County is in attainment for all controlled emissions, the area is in a maintenance program for ozone and therefore demonstrates conformity for nitrous oxides (NOx), which contribute to ozone formation. The updated AQCDR demonstrates that the implementation of the 2050 MTP will result in pollutant emissions that meet the air quality thresholds. 03.2L.
