As the number of vehicles on the nation’s roadways increased, air pollution from mobile sources was identified as an important national health concern. Recognizing this connection, the 1990 Clean Air Act Amendments require the projects in the Transportation Improvement Programs (TIP), and Long Range Transportation Plans conform to the Michigan State Implementation Plan (SIP). Conformity to a SIP means that planned transportation activities will not produce new air quality violations, worsen existing violations, or delay timely attainment of the National Ambient Air Quality Standards (NAAQS).
The Transportation Equity Act for the 21st Century (TEA-21) and its successor legislations, the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), the Moving Ahead for Progress in the 21st Century (MAP-21), and most recently the Fixing America’s Surface Transportation (FAST) Act reinforce the need for coordinated transportation and air quality planning through the metropolitan planning process.
Currently, EPA has designated Berrien County Michigan as Non- Attainment for the 2015 8-Hour Ozone NAQS effective January 16, 2018. (Federal Register, Volume 82, Number 220 - 82 FR 54232).
