NOAA publishes this final rule for certain regulations for the Florida Keys National Marine Sanctuary. This final rule makes technical corrections and modifications to several areas in the regulations. As part of these modifications, NOAA: amends the definition of coral to specifically include the common sea fan, Gorgonia ventalina and Venus sea fan, Gorgonia flabellum, which are both important sanctuary resources and are currently managed under the category "live rock"; specifies that "touching" coral is an injury and therefore, a prohibited activity in the FKNMS; amends the minimum distance between vessels and "divers down" flags to be 100 yards instead of 100 feet; clarifies that the prohibitions listed for Sanctuary Preservation Areas and Ecological Reserves also apply in Research-only Areas; and corrects several citations that were currently out of date.
