The general process for completing a Project Report and Environmental Document for a Transportation Project commences after reviewing project alternatives identified in the Project Study Report (PSR), and prior to the identification of impact mitigation measures. Upon completion of the appropriate environmental studies and identification of potential significant adverse impacts, the need for additional alternatives is determined.

When the environmental studies for the viable alternatives are complete, the Draft Project Report is finalized, approved and the Draft environmental document is circulated to the public. A preferred alternative is not recommended at the Draft environmental document stage. However, if presented, the discussion of the preferred alternative should document factors considered in its selection.

Following circulation of the Draft environmental document (the public review period), a public hearing is held. After analyzing the public hearing comments, a preferred Alternative is normally selected, which allows the preparation and approval of the Final environmental document, which is attached to the PR.

Selection of the Preferred Alternative authorizes the completion of the PR for project approval. When an EIS has been prepared, an Environmentally Preferred Alternative is identified in the Record of Decision (ROD) that is published in the Federal Register.
