The National Oceanic and Atmospheric Administration (NOAA) is issuing an interim final rule, temporary emergency rule in the Florida Keys National Marine Sanctuary (FKNMS) establishing three special use areas that will prohibit all entry except for restoration activities under a valid Office of National Marine Sanctuaries (ONMS) permit. These special use areas are needed for the relocation of coral nursery stock to cooler waters in response to an anticipated marine heatwave this summer with a high likelihood of coral bleaching. NOAA is establishing three special use areas, each of which are individually approximately 0.07 square miles and are within Federal waters of FKNMS. This temporary rule is necessary to prevent or minimize destruction of, loss of, or injury to sanctuary resources by facilitating restoration activities to improve or repair living habitats through protecting coral nursery stock at this site from potential impacts caused by anchor damage and/or fishing gear. These special use areas would expire within 60 days unless they are extended an additional 60 days. NOAA also requests comments on this action.
