Current federal transportation law supports PEL. U.S. Code Title 23, as amended by the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), the federal surface transportation act for years 2005-2009, requires many activities previously considered "good practice"-those that strengthen consideration of environmental issues and impacts within the transportation planning process and encourage the use of planning products during NEPA.

SAFETEA-LU also ventures into new areas such as asking for the use of visualization techniques and a new level of dialogue and interaction with the public (participation plans for stakeholder involvement) in discovering, describing, and analyzing strategies.

Environmental Considerations In Planning

Specifically, SAFETEA-LU Sections 3005, 3006, and 6001 require that:

Appendix A to Part 450-Linking the Transportation Planning and NEPA Processes (23 USC 139) describes how information, analysis, and products from transportation planning can be incorporated into and relied upon in NEPA documents under existing laws.
