Categorical Exclusions

The Federal Highway Administration (FHWA) defines Categorical Exclusions (CE) as actions that based on past agency experience with similar actions, do not involve significant environmental impacts.

Actions that meet the criteria for CEs in 40 CFR 1508.4and 23 CFR 771.117(a) and (b) are approved as CEs. Both (c)-list and (d)-list categorical exclusions may be approved by ADOT under the CE Assignment Program.

These projects are exempt from the requirements to prepare an Environmental Impact Statement (EIS) or an Environmental Assessment (EA).
