Programs and pollutants

Velarion’s copy of EPA’s ICIS-AIR download does not yet include its program, pollutant and Title V certification files, so this page does not list the Clean Air Act programs GENERAL DYNAMICS MISSION SYSTEMS INC - PLANTS 2&3 is under or the pollutants it is permitted for. The programs each evaluation and violation below was recorded under are shown with it. EPA’s free Detailed Facility Report lists both.
