3.6 Environmental Assessments

An Environmental Assessment (EA) is prepared when the proposed project does not meet the requirement of a CE, and when the significance of its impacts is uncertain. Actions that are not Class I (EIS) or Class II (CE) fall under the Class III (EA) classification.

If during the preparation of an EA, it is apparent that the project will have significant effects, an EIS should commence immediately. The FHWA may utilize an EA to determine whether the potential impacts are to a level significant enough to warrant completion of an EIS or issuance of a Finding of No Significant Impact (FONSI).
