FTA, in coordination with the Federal Highway Administration and the Federal Railroad Administration, developed 20 Qs & As that highlight amendments to 23 U.S.C. 139, Efficient Environmental Reviews for Project Decisionmaking, made by section 1304 of the FAST Act. These amendments became applicable on December 4, 2015. This new set of detailed Qs & As provide stakeholders and practitioners with a more thorough discussion of section 1304’s specific changes, such as changes to the definitions, programmatic reviews, lead agency and participating agency roles and responsibilities, project initiation process, alternative analysis, coordination plans, issue resolution, and project/process transparency.
