The National Oceanic and Atmospheric Administration (NOAA) expanded the boundaries of Gulf of the Farallones National Marine Sanctuary (now renamed Greater Farallones National Marine Sanctuary or GFNMS) and Cordell Bank National Marine Sanctuary (CBNMS) to an area north and west of their previous boundaries with a final rule published on March 12, 2015. The Final Rule entered into effect on June 9, 2015. At that time, NOAA postponed the effectiveness of the discharge requirements in both sanctuaries regulations with regard to U.S. Coast Guard (USCG) activities for six months, which has since been extended. Upon request by USCG, NOAA is considering allowing the following USCG discharges within part or all of GFNMS and CBNMS: (1) Untreated vessel sewage; (2) vessel graywater that does not meet the definition of clean as defined by the Federal Water Pollution Control Act (FWPCA), and (3) ammunition and pyrotechnics (flare) materials used in USCG training exercises for use of force and search and rescue.
