PUBLIC NOTICE
USACE Seeking public comment on Lower Columbia River Channel Maintenance Plan
Draft Dredged Material Management Plan and Environmental Impact Statement
Comment Period Opening Date: August 23, 2024
Comment Period Closing Date: October 7, 2024
Interested parties are hereby notified that the U.S. Army Corps of Engineers, Portland District (USACE) is seeking public comment on its Lower Columbia River Channel Maintenance Plan Draft Dredged Material Management Plan (DMMP) and Environmental Impact Statement (EIS).
PROJECT DESCRIPTION
The Lower Columbia River (LCR) is a dynamic system that poses an annual challenge for USACE to maintain the deep-draft Federal Navigation Channel (FNC) to the authorized depth of 43 feet and width of 600 feet. Sediment at the bottom of the LCR accumulates into mounds that can interfere with passing ships. It is important to have sufficient water depth for deep-draft vessels to safely transit. The goal of the DMMP is to develop a strategic plan for flexible, efficient operations for a minimum of 20 years to ensure the continued economic viability of this vital shipping gateway.
The Proposed Action reviewed in this Draft DMMP-EIS is continued Operations & Maintenance of the LCR FNC for specific, authorized purposes and in compliance with the Endangered Species Act and all other applicable treaties, laws, and regulations. The Draft DMMP-EIS presents the potential effects on the human environment from the No Action Alternative and two action alternatives at a program level with site- specific analysis where it is available. All three alternatives include continued dredging and placement at previously established sites. The action alternatives include additional suites of measures to extend the life of existing placement sites, allow for new placement methods and locations, and reduce dredging volumes. Further environmental review would occur where appropriate prior to phased implementation of the DMMP, as further discussed in the Draft DMMP-EIS. The Preferred Alternative is the Draft Recommended Plan, which is a refinement of Alternative 1.
NOTIFICATION
USACE has developed a draft Dredged Material Management Plan (DMMP) to support continued operation and maintenance of the Lower Columbia River Federal Navigation Channel (LCR FNC) for the next 20 years. The DMMP was subject to environmental review via a draft Environmental Impact Statement (EIS) pursuant to the National Environmental Policy Act (NEPA) and the Washington State Environmental Policy Act (SEPA). The EIS was jointly prepared by USACE and the Lower Columbia River Sponsor Ports (Sponsor Ports are the Port of Longview, Washington; the Port of Kalama, Washington; the Port of Woodland, Washington; the Port of Vancouver USA, Washington; and the Port of Portland, Oregon). USACE was the NEPA lead agency and the Port of Longview was the SEPA nominal lead agency for the Washington Ports. Combined, the DMMP and EIS are an integrated report known as the Draft DMMP-EIS. The Draft DMMP-EIS was prepared in compliance with Corps policy for the preparation of DMMPs, and the requirements of NEPA and SEPA. USACE will also issue a separate public notification of the proposed discharges of dredged or fill material described in the DMMP-EIS, in accordance with agency regulations and section 103 of the Marine Protection, Research, and Sanctuaries Act (MPRSA, also known as the Ocean Dumping Act) and section 404 of the Clean Water Act.
