The National Oceanic and Atmospheric Administration (NOAA) Office of Marine and Aviation Operations (OMAO) submitted a national consistency determination to address potential coastal effects from vessel operations undertaken by OMAO from 2023-2038. OMAO vessel operations include routine activities such as vessel movement, anchoring, waste handling and discharges, and vessel repair and maintenance. OMAO may also operate active acoustic systems and other sensors, data collection systems, uncrewed marine and aircraft systems, small boats, and conduct over the side operations. The NOAA fleet needs to be modernized by updating vessels in the existing fleet and replacing aging vessels with new vessels built specifically to support NOAA missions. This action is subject to review for consistency with the enforceable policies of Maine Coastal Program under 15 CFR 930, subpart C.
