National Environmental Policy Act: Implementing Procedures; Revision to Categorical Exclusions for U.S. Geological Survey (516 DM 9)

Résumé

In accordance with the National Environmental Policy Act of 1969 (NEPA) and the Council on Environmental Quality regulations implementing NEPA, the U.S. Geological Survey (USGS) in the Department of the Interior (the Department) is revising two existing categorical exclusions included in the Department of the Interior's Departmental Manual 516 DM 9. The revisions to the categorical exclusions pertain to two types of activities conducted by the USGS: The excavation of trenches across potentially active faults to assess the history of earthquakes along those faults; and the removal of hydrologic and water-quality monitoring structures and equipment and restoration of the sites. USGS experience with these activities indicates that they do not normally have the potential for significant environmental impacts in the absence of extraordinary circumstances. The intent of the revisions is to improve the efficiency of the environmental review process.
