AGENCY:

Department of the Army, U.S. Army Corps of Engineers, DoD.

ACTION:

Notice.

SUMMARY:

In accordance with the requirements of the National Environmental Policy Act (NEPA), the U.S. Army Corps of Engineers (USACE or Corps) Kansas City District, in cooperation with U.S. Environmental Protection Agency, has prepared a Draft Evaluation Report and Draft Environmental Impact Statement Start Printed Page 19429(DEvR/DEIS). This study identifies deficiencies in the foundation of the existing dam that could lead to failure in the event of a major earthquake. In addition, minor deficiencies were identified in the existing tainter gate system and with the existing amount of freeboard that could adversely affect performance of the dam during a major flood event. Failure of the structure in the event of a major earthquake or flood would have significant adverse impacts on the human environment, including property damage and potential loss of human life. Considering these potential significant impacts on the human environment, and in accordance with the NEPA, the Corps initiated preparation of an Evaluation Report and Environmental Impact Statement (EvR/EIS). This DevR/DEIS presents a screening level analysis of several alternatives considered during scoping and a detailed analysis of four alternatives that would minimize the potential for loss of human life and property damage related to failure of the dam in the event of a major earthquake. These included: Restricted Lake Operation; Stabilize Foundation Soil with Drawdown; Stabilize Foundation Soil without Drawdown; and Enlarge Embankment. The DEIS identifies Stabilize Foundation Soil without Drawdown as the Corps' Preferred Alternative. In addition, the Corps considered the “No Action” Alternative. The Corps also identified potential measures to ensure satisfactory performance of the dam during a major flood. These measures include minor repair work on the existing tainter gate system and construction of a “Jersey barrier” wall across the top of the dam to increase freeboard and prevent wind and wave wash. The DEvR/EIS presents a detailed study of the environmental impacts of the five alternatives listed above, the minor measures needed to ensure satisfactory performance of the dam during a major flood, and an interim measure proposed to enhance public safety.

SUPPLEMENTARY INFORMATION:

The proposed project must also address environmental impacts relative to the Clean Air Act, Clean Water Act, Endangered Species Act and the Fish and Wildlife Coordination Act (FWCA). In accordance with the NEPA, the DEvR/DEIS evaluates reasonable alternatives for the USACE's decision making process. As required by NEPA, the USACE also analyzes the “no action” alternative as a baseline for gauging potential impacts. As part of the public involvement process, notice is hereby given by the USACE-Kansas City District of a public meeting to be held at the Holiday Inn, 530 Richards Drive, Manhattan, KS, beginning at 7 p.m. on May 2, 2002. The public meeting will allow participants the opportunity to comment on the DEvR/DEIS prepared for the Tuttle Creek Dam Safety Assurance Study.
