Notes
This Washington State law requires that no state agency, metropolitan planning organization, or local government may approve or fund a transportation plan, program, or project in a nonattainment area without a conformity determination showing compliance with the state implementation plan for air quality under the federal Clean Air Act. The law assigns responsibility for conformity determinations to the administering agency and directs the Department of Ecology and Department of Transportation to adopt rules for federally funded projects. Projects limited in scope to preservation or maintenance are exempt from conformity determination requirements.
