  Criteria pollutants   EPA no longer tracks air pollutant emissions with the AIRS database and emissions data presented in this report should be considered obsolete. The data were extracted from AIRS on Septembers 8, 2000. Since that time, emissions data has been removed from the AIRS database, and there will be no further updates or revisions. AIRS Source reports will be removed from the AIRSDATA website during the first quarter of 2001.   EPA AIRS database.
