Abstract: The U.S. Army Corps of Engineers, Mississippi Valley Division, New Orleans District, has prepared this Supplemental to Individual Environmental Report #12 (IERS #12.a) to evaluate the potential construction impacts associated with the proposed project revisions to the original IER #12 Gulf Intracoastal Waterway (GIWW), Harvey and Algiers Levees and Floodwalls project area. Proposed design changes since the original IER #12 GIWW, Harvey and Algiers Levees and Floodwalls Jefferson, Orleans, and Plaquemines Parishes, Louisiana document would result in additional impacts not addressed in IER #12. Those modifications and anticipated impacts are discussed in this supplemental. The proposed action and the area of impact are located within the IER #12 project area in Jefferson Parish, LA. The Harvey-Westwego, Gretna-Algiers, and Belle Chasse Interagency Performance Evaluation Task Force polders are located within the Orleans, Jefferson and Plaquemines parishes. The total estimated population for these three parishes in 2006 was 687,261. It is also important to note the presence of the U.S. Environmental Protection Agency designated Bayou aux Carpes Clean Water Act Section 404(c) area within this Westbank and Vicinity project area. These nationally significant wetlands are protected under the Clean Water Act Section 404(c), which authorizes the administrator of the EPA to deny or restrict the use of any defined area for specification as a disposal site, whenever the administrator determines, after notice and opportunity for public hearings, that the discharge of such materials into such area would have an unacceptable adverse effect on municipal water supplies, shellfish beds and fishery areas (including spawning and breeding areas), wildlife, or recreational areas. All potential impacts to this unique environment associated with the proposed action are thoroughly explained in IER #12, sections 3.1.7, 3.2.2, 6, 7, and Appendix K. There are no impacts to the Bayou aux Carpes area as a result of the proposed action in this supplemental.
