The USDA Forest Service (FS) National Programmatic Agreement (nPA) for Phasing Section 106 of the National Historic Preservation Act for Large-Scale Multi-Year Undertakings provides the agency an alternative approach to phase and defer the Section 106 process for long-term wildfire prevention, forest health improvement, and other large-scale undertakings. Under the terms of the nPA, the FS engages consulting parties at the earliest design stages of the undertaking, requires the FS to develop a Heritage Implementation Plan prior to a project decision, and allows the agency to complete the Section 106 process after a project decision is made.
