The U.S. Department of Transportation (DOT) October 6 issued final regulations implementing many of the reforms to the categorical exclusion (CE) process required by the 2012 “Moving Ahead for Progress in the 21st Century” (MAP-21) surface transportation law. CEs are the least burdensome form of environmental review and are used on projects that have little or no environmental impacts. The new DOT regulations focus on key ARTBA-supported changes to the CE process including the creation of new categories of CEs, fewer steps in the CE process for routine projects, and enhancing state authority to administer CEs. These revisions to the CE process are intended to help reduce unnecessary project delay. ARTBA will monitor the impacts these key changes have on project delivery and continue to advocate additional ways to expedite the delivery of needed transportation improvements.
