15-Day Notice
This Public Notice announces the Section 408 Review of the Columbia Natural Gas, Clinton Street Utility Boring Project in Walla Walla, Washington. The U.S. Army Corps of Engineers (USACE) is reviewing Columbia Natural Gas’s proposal to replace approximately 200 feet of pipe and provide natural gas distribution pressure. The new natural gas line will cross under the Mill Creek Channel, which is part of the Mill Creek Flood Control Project within the City of Walla Walla, Walla Walla County, Washington.
Alteration of a federally authorized project: Columbia Natural Gas proposes to install 200 feet of pipe (via Horizontal Directional Drilling) and provide natural gas distribution pressure along Clinton Street, of which portions will cross under the Mill Creek Flood Control Project. The pipeline is needed to provide stable pressures in the surrounding area. Since the proposed pipe replacement would cross portions of the Mill Creek Flood Control Project, USACE is required to ensure the project would not adversely affect the operation or performance of the federally authorized infrastructure. 33 USC 408 (Section 408) provides authority to the Secretary of the Army to grant permission to the alteration or modification of USACE federal civil works projects when, in the judgement of the Secretary, such alteration or modification will not be injurious to the public interest and will not impair the usefulness of the project.
Consideration of Comments: USACE is requesting comments regarding the proposed pipe replacement from the public; federal, state, and local agencies and officials; and other interested parties. Comments will be considered in determining whether it would be in the public interest to approve the proposed project.
All comments received will become part of the official record and are subject to public release under the Freedom of Information Act including any personally identifiable information such as names, phone numbers, and addresses.
Comments: Interested parties should submit comments regarding the Clinton Street Natural Gas Pipe Replacement Project in the City of Walla Walla, Washington to USACE.
