ATTENTION: APTI has moved to a new website
EPA has transferred the classroom and self-instructional training functions of the APTI website (www.epa.gov/apti) to the new Air Pollution Training Institute (APTI) Learning Management System: APTI-Learn (www.apti-learn.net).
Videos on Demand are still available on this web site at this time. They will eventually be transferred to the APTI-Learn website.
