Allen's air quality reflects the DFW metroplex's northern Collin County corridor, with vehicle emissions from US-75 the primary local source in this major Dallas northern suburb. The flat North Texas plain provides reasonable wind dispersal, while the broader metropolitan ozone from vehicle and Barnett Shale gas emissions affects the entire northern corridor and summer ozone is the primary warm-season air quality concern.
