This document focuses largely on air emissions from two industrial facilities in Idaho. During the time that ATSDR evaluated these air emissions, the name of one of the facilitieschanged. Specifically, when ATSDR began this health consultation, FMC Corporation owned andoperated one of the facilities of concern. Now, that facility is owned and operated by Astaris. Allreferences to "FMC" and the "FMC facility" in this health consultation, therefore, refer to what is currently the Astaris facility.
