The Nationwide Programmatic Agreement Section 106: What You Need to Know

The Nationwide Programmatic Agreement (NPA) Section 106 is a crucial aspect of the National Historic Preservation Act (NHPA) that aims to preserve the United States` historical and cultural resources. It is an agreement between the Advisory Council on Historic Preservation, the Federal Highway Administration, and the State Historic Preservation Offices that outlines the procedures for carrying out Section 106 reviews for transportation projects nationwide. Here`s what you need to know about this agreement.

What is Section 106?

Section 106 is a provision of the NHPA that requires federal agencies to consider the effects of their actions on historic resources. It applies to all projects that receive federal funding or approval, including transportation projects such as highways, bridges, airports, and transit systems. Section 106 requires agencies to consult with the State Historic Preservation Officer, Indian tribes, and other interested parties to identify and evaluate historic properties, assess the effects of the proposed project on these properties, and develop measures to mitigate any adverse effects.

What is the NPA?

The NPA is a tool that agencies can use to streamline the Section 106 review process for transportation projects. It was first created in 2005 to expedite the review of highway projects but was later expanded to include all types of transportation projects. The NPA sets forth a series of standard procedures and timelines for the Section 106 review process, which can vary depending on the size and complexity of the project.

What are the Benefits of the NPA?

The NPA provides several benefits to federal agencies, State Historic Preservation Offices, and other stakeholders involved in the Section 106 review process. For agencies, the NPA offers predictable timelines and procedures that help to expedite the review process, reducing delays and ensuring that projects can move forward without unnecessary delays. The NPA also provides clear guidance on the types of projects that may be exempt from the Section 106 review process, such as routine maintenance or minor rehabilitation work.

For State Historic Preservation Offices, the NPA provides a more efficient and streamlined review process that allows them to focus their resources on the most significant historic resources and those with the greatest potential for adverse effects. The NPA also includes provisions for public involvement, ensuring that interested stakeholders have an opportunity to provide input and feedback on the proposed project.


The Nationwide Programmatic Agreement Section 106 is a critical tool that helps to protect the United States` historic and cultural resources while allowing transportation projects to move forward. By providing a standardized and streamlined process for the Section 106 review process, the NPA ensures that projects can be completed efficiently while preserving our nation`s heritage. If you`re involved in a transportation project that may be subject to the Section 106 review process, be sure to consult with your State Historic Preservation Office and other stakeholders to ensure that your project is in compliance with all applicable regulations and guidelines.
