Air Quality impacts are evaluated for all Idaho Transportation Department (ITD)
federally funded transportation projects to determine if the project will cause
or contribute to a violation of National Ambient Air Quality Standards. ITD’s
mission is to improve air quality by ensuring all ITD projects and operations
comply with federal, state and local air quality laws and regulations, and by
promoting strategies which reduce emissions of motor vehicle pollutants.
