Department of the Army, Corps of Engineers July 2018 – Federal Register Recent Federal Regulation Documents

The U.S. Army Corps of Engineers (Corps) Omaha District has prepared a Final Environmental Impact Statement (EIS) to analyze the direct, indirect, and cumulative effects of a water supply project called the Northern Integrated Supply Project (NISP or Project) in Larimer and Weld Counties, CO. The purpose of NISP is to provide the Participants, a group of 15 water providers and communities, with approximately 40,000 acre-feet (AF) per year of new, reliable municipal water supply through a regional project coordinated by the Northern Colorado Water Conservancy District (Northern Water). NISP would result in direct impacts to jurisdictional waters of the U.S., including wetlands. The placement of fill material into waters of the U.S. requires authorization from the Corps under Section 404 of the Clean Water Act. Northern Water is the applicant for the Section 404 permit, acting on behalf of the Participants. In accordance with Section 176 of the Clean Air Act a Draft General Conformity Determination has been prepared for the Project.

The U.S. Army Corps of Engineers (``USACE''), Memphis District, Vicksburg District, and the New Orleans District, is announcing its intent to prepare Supplement II (SEIS II) to the Final Environmental Impact Statement, Mississippi River and Tributaries (MR&T) Project, Mississippi River Mainline Levees and Channel Improvement of 1976 (1976 EIS), as updated and supplemented by Supplement No. 1, Mississippi River and Tributaries Project, Mississippi River Mainline Levee Enlargement and Seepage Control of 1998 (SEIS I) to the 1976 EIS, to cover construction of remaining authorized work on the Mississippi River mainline levees (MRL) feature. Over the past twenty years since the finalization of SEIS I, USACE has determined that various sections (reaches) of the mainline levee system are deficient in varying amounts, and that certain remedial measures need to be undertaken to control seepage and to raise and stabilize the deficient sections of the levee to protect the lower Mississippi River Valley against the Project Design Flood (PDF) and maintain the structural integrity of the MRL system. The Proposed Action of SEIS II is to supplement and, as necessary, augment the 1976 EIS and SEIS I using the primary MR&T goals of: (1) Providing flood protection from the PDF; and (2) developing an environmentally sustainable project; formulating alternatives; identifying significant resources; assessing the direct, indirect, and cumulative impacts to those resources; investigating and environmentally assessing potential borrow areas; developing mitigation measures; and evaluating and selecting a preferred method for the construction of necessary authorized MRL Project features, which may include but are not limited to, implementing seepage control measures and the construction of various remediation measures for deficient levee reaches to bring these reaches to the project design grade. SEIS II will evaluate the potential direct, indirect, and cumulative impacts for an array of alternatives, including a No Action alternative.

The Department of Defense (DoD) is publishing this notice to announce that the following Federal Advisory Committee meeting of the Inland Waterways Users Board will take place.
