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 CENTURY ALUMINUM OF SOUTH CAROLINA INC 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.
