Michigan City's air quality reflects the Lake Michigan southern shoreline position in the Indiana Dunes corridor, with vehicle emissions from I-94 and the surrounding NIPSCO Michigan City power station and the former Bethlehem Steel legacy generating elevated industrial background alongside the primary local vehicle sources. Lake Michigan's consistent northerly winds generally provide maritime ventilation, while summer regional ozone from the Chicago-Gary industrial corridor is the primary warm-season concern.
