The United States Department of Navy in cooperation with U.S. Coast Guard proposes to conduct certain activities as part of the Atlantic Fleet Training and Testing Phase IV needed to meet mission requirements along the East Coast of the U.S., the Gulf of Mexico, and portions of the Caribbean Sea. This includes activities occurring at Navy and Coast Guard pierside locations; port transit channels, bays, harbors, inshore waterways, and civilian ports; during transits between homeports and operating areas; and on the high seas. This action is subject to review for consistency with the enforceable policies of Maine Coastal Program under 15 CFR 930, subpart C. More information about the project can be found by going to the US Navy Supplemental Environmental Impact Statement page or by reading the 2024 USN AFTT CCD document. Public comments will be accepted through January 11, 2025 and can be sent to DMRCoastalProgram_FC@maine.gov.
