The BLM’s National Programmatic Agreement (nPA) governs its Section 106 compliance activities nationwide and primarily in eleven western states where the BLM administers most of its surface lands and mineral estate.  The nPA governs the BLM’s activities on federal, state, and private lands that have the potential to impact historic properties and authorizes BLM state offices to maintain protocol agreements with individual SHPOs. These two-party agreements are the primary means by which the BLM achieves efficiency and consistency for Section 106 reviews within a state. Protocols establish thresholds for classes of undertakings requiring (or not requiring) consultation with SHPOs, establish documentation and data-sharing standards, stipulate annual reporting requirements, and govern other aspects of SHPO consultation. The nPA also outlines a framework for how the BLM will consult with Indian Tribes in the context of an ongoing government-to-government relationship and to obtain their views on the potential effects on historic properties of significance to them.
