Non-Major (Air Pollutant) Source Construction and Operation Permit Applications – Air Quality Forms

Minor sources of air pollution are those that have the potential to emit air pollutants at rates below defined major source thresholds. These sources generally require a Chapter 2 pre-construction review permit prior to commencement of construction and a Chapter 2 operating permit following completion of construction. In the District, minor sources include gas stations, dry cleaners, auto body shops, sites using generators, and small printing facilities.
