Abstract: The purpose of this study is for CEMVN to develop a management plan for the placement of material dredged for the maintenance and operation of the Calcasieu Ship Channel. The actions and strategies set forth in the DMMP/SEIS would provide for the management of dredged material for a minimum period of 20 years while updating and redefining the base plan/Federal standard for the project. Currently, the project does not have the adequate dredged material disposal capacity needed to maintain the channel to authorized depths. The gross 20-year dredging capacity required to maintain the channel is approximately 97 million cubic yards, while the existing confined disposal capacity is only five million cubic yards. Existing discharge sites are at or near capacity, and past maintenance deficiencies have resulted in substantial erosion of discharge facilities into adjacent water bodies. As a result, it has become necessary for CEMVN to reduce channel widths in some reaches. The Calcasieu Ship Channel supports a thriving commercial navigation industry. The tonnage of commodities handled at the ship channel’s docks makes the Lake Charles Harbor & Terminal District (Port of Lake Charles) the 11th largest seaport in the U.S. and the second largest Strategic Petroleum Reserve facility. In 2006, more than 58,000 jobs in Louisiana were related to business activity at the port’s terminals. The marine cargo and vessel activity at the port generated $7.9 billion of total economic activity in Louisiana in the same year. Without action, navigation on the channel may be restricted as a result of reduced channel dimensions.
