Mobile Sources

The Division of Mobile Source Program’s mission is to improve air quality and public health through the implementation of programs and projects that will reduce emissions from motor vehicles, off-road equipment and associated fuels-related sources. Programs include the Illinois Vehicle Inspection and Maintenance (VIM) program which oversees the testing of over 2.1 million vehicles a year in the Chicago and Metro-East St. Louis areas, and the Illinois Clean Air Program which includes the issuance of rebates for the use of alternative fuels or grants to reduce emissions from locomotives, school buses or other large diesel engines, and the oversight of fuel distribution sources such as gasoline dispensing facilities and gasoline delivery trucks.
