NHPA Process

As the lead federal agency for the B2H Project, BLM is responsible for ensuring the project complies with Section 106 of the National Historic Preservation Act (NHPA).

BLM is consulting with the Advisory Council on Historic Preservation (ACHP), an independent federal agency promoting the preservation, enhancement and productive use of our nation’s historic resources, and consulting parties to identify, evaluate and assess effects to historic properties. In addition, other consulting parties are also assisting with development of a project programmatic agreement which outlines the path to resolving adverse effects to historic properties.

About Historic Properties

Historic properties are any prehistoric or historic district, site, building, structure, or object included in, or eligible for inclusion in, the National Register of Historic Places. Eligibility is based on the historic property’s age (generally at least 50 years old), significance and integrity.

About NHPA and Section 106 Consultation

The NHPA is a federal law intended to “preserve the historical and cultural foundations of our nation.” The NHPA was developed in recognition that historic resources are valuable for knowing and understanding our past, providing a sense of roots and identity, recognizing and commemorating the past, and inspiring future generations.

Section 106 of the NHPA directs federal agencies to consider the effects of their actions on historic properties and to consider ways through consultation to avoid, minimize or mitigate for effects to historic properties. Consulting parties may include affected tribes, historic preservation offices, local governments, historically and culturally focused organizations, and individuals who have a demonstrated interest in the preservation of potentially affected historic properties.
