Streamline Transit Projects Act

S 3284, the Streamline Transit Projects Act, allows large urban transit agencies (with populations over 200,000) that prove capacity to handle environmental reviews for certain transit projects. Eligible agencies would assume responsibility for determining which projects qualify as "categorical exclusions" (projects not requiring full environmental impact studies), replacing federal oversight for these specific activities. Agencies must follow public disclosure rules, sign agreements with the Transportation Secretary, and become legally liable for compliance, while the federal government monitors performance and can terminate agreements for poor execution. This bill directly affects major transit authorities in large cities, shifting a key federal review process to local agencies.
