The Handbook clarifies and provides information to project managers on the successful integration of Section 106 and the National Environmental Policy Act (NEPA) with a specific focus on Section 106 as it applies to transportation projects for which the project applicant is a state department of transportation (DOT). The Handbook is not a beginner introduction to the Section 106 process, nor is it an exhaustive technical guide for Section 106 practitioners.

Practical tips include preparing for Section 106 consultation, defining an area of potential effects (APE), inviting consulting parties and public involvement; evaluating eligibility for the National Register of Historic Places;, determining and resolving adverse effects, developing memoranda of agreement (MOAs) and programmatic agreements (PAs), and using alternative procedures to satisfy Section 106 requirements.
