Replacement Terminal Environmental Assessment

​2. What is the difference between an Environmental Assessment and an Environmental Impact Statement?

An Environmental Assessment (EA) is typically performed to determine the environmental impacts of a project on the surrounding environment when the anticipated outcome of the EA is that there are no mitigatable environmental impacts. An Environmental Impact Statement (EIS) is performed when there are known or anticipated significant impacts that cannot be mitigated to less than significance. For airport projects, the FAA defines and determines the extents and thresholds for impacts to the environment.

 

For the Replacement Terminal environmental planning, an EA has begun based on FAA input. If, in the view of the FAA during the EA process, it is determined there may be significant impacts that cannot be mitigated to less than significance, the project would be changed from an EA into an EIS and directed by the FAA.
