NEPA Re-evaluation

FHWA and CDOT will re-evaluate the FEIS in light of the new information discovered and developed since the ROD in order to determine if additional National Environmental Policy Act (NEPA) documentation is required. The re-evaluation will analyze both the changes in the environmental setting (new gas well, previously unidentified cultural resources, etc.) as well as changes to the proposed action and the effect those will have on various environmental resources. If there are new significant environmental impacts, a Supplemental EIS will be prepared. If there are no new significant environmental impacts, a written report documenting the re-evaluation will be prepared.
