The applicant, Port Charles Harbor, is an existing harbor facility which offers wet/dry slips, mechanical & refinishing service, boat restoration, and a ship store. The applicant seeks authorization to conduct maintenance dredging operations within the harbor, as multiple high water events, specifically the flood event of 2019, have caused the re-deposition of fine materials within the harbor. Previous permitting authorized the construction of the harbor, as well as subsequent permitting that authorized the placement of materials into the Mississippi River in an open water disposal site just outside the harbor’s mouth. The project purpose is to reissue the maintenance dredging permit previously authorized to maintain the harbor in such a condition that recreational vessels have a safe ingress and egress to the site. The proposed dredging will only remove material deposited by the river and will not alter the previously authorized contours of the Harbor. The applicant seeks reauthorization to continue with periodic maintenance by placing dredged material into the river just outside the harbor entrance at river mile 221.5.  The project is located on the right descending bank of Mississippi River at approximate mile 221.5, St. Charles County, Missouri. Specifically, the project is located on the Grafton USGS quadrangle maps, Section 08, Township 48 North, Range 5 East.  The Public Notice comment period is open from June 13, 2023 through July 05, 2023.
