This document corrects coordinates published on July 1, 2003 for a no-entry zone in the Florida Keys National Marine Sanctuary. The no-entry zone was established by a temporary rule and became effective June 26, 2003 until August 25, 2003. That temporary rule created two no-entry zones in the vicinity of White Bank Dry Rocks off of Key Largo to prevent the inadvertent spread by swimmers and snorkelers of infectious agents associated with diseased corals in the two zones. Each no-entry zone is approximately 0.25 square miles in size. This document corrects the coordinates of White Bank South Patch that were incorrectly described in the temporary published on July 1, 2003.
