Federal Compliance

The National Environmental Policy Act (NEPA) and the National Historic Preservation Act (NHPA) require federal and state agencies and projects with federal support to take into account the impact of any undertaking on cultural resources. Bunyak Research Associates can assist federal and state agencies and their consultants to comply with NEPA and sections 106 and 110 of NHPA for historic properties.

Bunyak Research Associates has prepared historic resources survey reports; preliminary planning documents that include reconnaissance surveys, feasibility studies, and Environmental Overview Studies; mitigation documentation and a wide range of technical reports including, Environmental Assessments, Environmental Impact Studies and more recently, Tiered EIS documents.

The project included field survey for identification of potentially eligible historic resources to the National Register of Historic Places, preparation of technical memorandums, a final survey report, and an analysis of the potential effects on identified historic resources.
