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.
