The DCHC MPO adopted the Triangle Region Transportation Conformity Determination Report on December 11, 2019. The Transportation 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, based on the 1997 NAAQS (National Ambient Air Quality Standard) for ground level ozone. The MPO recently amended the 2045 Metropolitan Transportation Plan (MTP) and adopted the FY 2020-2029 Transportation Improvement Program (TIP) and these actions required the MPO to adopt an updated Conformity Determination Report.
