This mini-peer exchange, held February 18, 2016, provided an overview of NCHRP 25-43: Navigating Multi-agency NEPA Processes to Advance Multimodal Transportation Projects. The research objectives were to: (1) characterize the challenges inherent in satisfying the NEPA requirements of more than one U.S. DOT agency; (2) identify strategies and tactics used to overcome these challenges; and (3) suggest new and innovative strategies.
AASHTO hosted a Virtual Peer Exchange (VPE) that featured three State DOTs discussing their experience with alternative project delivery and the NEPA process. The three states that presented are Pennsylvania,…
The National Environmental Policy Act (NEPA) establishes policy and goals for the protection, maintenance, and enhancement of the environment across the United States, and it provides a process for implementing these goals within federal agencies.
Learn more about when NEPA is required, who oversees the process, and why it is important.
NEPA Assignment is a process states can choose to undertake where they assume federal responsibility for transportation projects in exchange for a faster federal review process.
