Public invited to comment on renewal of the ADOT, FHWA agreement for project environmental reviews

April 11, 2024

Draft Memorandum of Understanding available for comment until May 10

PHOENIX – The Federal Highway Administration (FHWA) and the Arizona Department of Transportation are proposing to renew an agreement through which ADOT assumes FHWA’s authority for approval of federal environmental review documents for proposed projects. 

A draft Memorandum of Understanding that would continue this agreement, known as NEPA (National Environmental Policy Act) Assignment, has been posted to the Federal Register and is available for comment until May 10.

The agreement, established in 2019, allows a state to apply for and assume decision-making and legal responsibility for meeting NEPA requirements and other federal environmental laws otherwise administered by FHWA for projects. Congress established the program to help streamline environmental reviews for federally funded highway projects. Arizona is among eight states, including California and Texas, that currently have this authority. NEPA requirements apply to all projects that use federal funds.
