The National Oceanic and Atmospheric Administration (NOAA) issues a temporary rule prohibiting all entry into two areas off the east side of Key Largo within federal waters of the Florida Keys National Marine Sanctuary. The combined areas are approximately 0.50 square miles in size. This temporary rule is necessary to prevent injury to, and destruction of, living coral from stress to diseased coral within the close areas, and to protect healthy coral from human- caused contamination.
