Does the information documenting the absence of endangered or threatened species have to be updated?
The potential for endangered or threatened species to be present within a project area should be established or confirmed at key phases of the project. At a minimum, it is recommended that this occur when the RI/FS work plan is prepared, prior to completion of the FS or preparation of the proposed plan (if more than two years has elapsed), during remedial design, and at each Five Year Review.
