AASHTO PH09-1, Practitioner's Handbook: Using the SAFETEA-LU Environmental Review Process, was prepared to help state transportation agencies and their partners move projects through the environmental review required under the federal surface transportation legislation of that period. The handbook explains the sequence of the process, the roles of the agencies involved, the documentation expected at each stage, and the points at which decisions are made. It is written for project managers, environmental staff and consultants who need a practical guide rather than the statute itself.
