Any change to MAG's RTP — TransPlan50 — that might increase vehicle air pollution must undergo testing to ensure the additional emissions do not exceed limits set by the State Division of Air Quality (DAQ) with the Environmental Protection Agency (EPA).
This testing is completed using the latest EPA-approved air quality model, an updated Travel Demand Network including all the proposed changes, and input from other air quality agencies. The result is the Air Quality Conformity Report below.
