EIS's are prepared for HHS organization actions when:

1. Evaluation of data in an Environmental Assessment (EA) leads to a finding by the responsible official that a proposed action may significantly affect the quality of the human environment under the criteria in 40 CFR 1508.14 and 1508.27; or

2. Initial evaluation by the responsible official of any action, including any action for which an EA would otherwise be required, establishes that significant environmental effects may be associated with one or more of the probable courses of action being considered.
