Omaha, Neb. – A draft supplemental environmental assessment for proposed construction changes at the cultural interpretive center located on the Fort Berthold Indian Reservation in McKenzie County, North Dakota is currently available for public review. The draft supplemental EA evaluates the environmental impacts of increasing the project footprint by approximately four acres. 

The purpose of the proposed project is to increase the size of the cultural interpretive center by approximately 15,000 square feet, construct a 500-seat amphitheater adjacent to the interpretive center, alter the location of the proposed parking areas, and install an on-site septic treatment system that would discharge treated sanitary effluent to Lake Sakakawea. The revised plans would result in approximately four additional acres of disturbance that were not evaluated as part of the original 10 acres described in the 2005 EA. 

This document supplements the “2005 Environmental Assessment and Finding of No Significant Impact (FONSI), Cultural Interpretive Center Project, Garrison Dam / Lake Sakakawea” which disclosed the potential environmental impacts of constructing a cultural interpretive center and associated parking area, earth lodges, a tepee village, a scenic overlook, access road and utility corridor, a pedestrian bridge, and walking trails. Since approval of the 2005 EA and FONSI, the earth lodges, access road and utility corridor have all been constructed. 

The public is encouraged to provide comments on the draft supplemental environmental assessment, which is available for viewing at: http://www.nwo.usace.army.mil/Missions/CivilWorks/Planning/ProjectReports.aspx. Comments can be mailed to: U.S. Army Corps of Engineers, Omaha District; CENWO-PMA-C; ATTN: Matthew Vandenberg; 1616 Capitol Avenue; Omaha, NE 68102-4901. Comments can also be emailed to: cenwo-planning@usace.army.mil. Comments must be postmarked or received no later than March 31, 2018. 

This draft supplemental EA is consistent with the National Environmental Policy Act of 1969, as amended, the Council on Environmental Quality’s regulations for implementing NEPA (40 CFR 1500-1508), the Corps’ regulations for implementing NEPA (33 CFR 325 and Engineering Regulation 200-2-2) and other applicable environmental laws and regulations.
