Information concerning the regulations may be obtained at the Office of the Commander, 11th Coast Guard District in Alameda, California or at the Office of the District Engineer, Corps of Engineers in San Francisco, California. Refer to charted regulation section numbers. SECURITY ZONE Security Zone: 33 CFR 165.1183 - The Coast Guard has established moving and fixed security zones, extending 100 yards around and under all cruise ships and tanker vessels, that enter, are moored in, anchored in, or depart from the San Francisco Bay, California and Delta ports. When a cruise ship and/or tank vessel approaches within 100 yards of a vessel that is moored, or anchored, the stationary vessel must stay moored, or anchored, while it remains within the cruse ships's and/or tank vessel's security zone, unless it is either ordered by, or given permission from the COTP San Francisco Bay to do otherwise. Entry can be authorized by the Captain of the Port of San Francisco Bay, at telephone number 510-437-3073 or VHF-FM channel 16 (156.8 MHz). SUPPLEMENTAL INFORMATION Consult U.S. Coast Pilot 7 for important supplemental information. CAUTION - LIMITATIONS Limitations on the use of radio signals as aids to marine navigation can be found in the U.S. Coast Guard Light Lists and National Geospatial-Intelligence Agency Publication 117. Radio direction-finder bearings to commercial broadcasting stations are subject to error and should be used with caution. POLLUTION REPORTS Report all spills of oil and hazardous substances to the National Response Center via 1-800-424-8802 (toll free), or to the nearest U.S. Coast Guard facility if telephone communication is impossible (33 CFR 153). AIDS TO NAVIGATION Consult U.S. Coast Guard Light List for supplemental information concerning aids to navigation. CAUTION - TEMPORARY Temporary changes or defects in aids to navigation are not indicated. See Notice to Mariners. CAUTION - DREDGED AREAS Improved channels are subject to shoaling, particularly at the edges. CAUTION - SUBMARINE PIPELINES and CABLES Additional uncharted submarine pipelines and submarine cables may exist within the area of this chart. Not all submarine pipelines and submarine cables are required to be buried, and those that were originally buried may have become exposed. Mariners should use extreme caution when operating vessels in depths of water comparable to their draft in areas where pipelines and cables may exist, and when anchoring, dragging or trawling. Covered wells may be marked by lighted or unlighted buoys. PRECAUTIONARY AREA Traffic within the Precautionary Area may consist of vessels making the transition between the Main Ship Channel and one of the established traffic lanes. Mariners are advised to exercise extreme caution when navigating within this area. When passing Traffic Lane Lighted Buoys "S", "W", or "N", inbound vessels should contact pilot boat on channel 13 for boarding instructions. NOAA WEATHER RADIO BROADCASTS The NOAA Weather Radio stations listed below provide continuous weather broadcasts. The reception is range is typically 20 to 40 nautical miles from the antenna site, but can be as much as 100 nautical miles for Stations at high elevations. Mt. Pise, CA KHB-49 162.40 MHz WX2 Mt. Umunhum, CA KEC-49 162.55 MHz WX1 Mt. Umunhum, CA WWF-64 162.45 MHz WX5 WARNING - PRUDENT MARINER The prudent mariner will not rely solely on any single aid to navigation, particularly on floating aids. See U.S. Coast Guard Light List and U.S. Coast Pilot for details. AUTHORITIES Hydrography and Topography by the National Ocean Service, Coast Survey, with additional data from the Corps of Engineers, Geological Survey, and U.S. Coast Guard. NOTE - Z Under the Clean Water Act, Section 312, all vessels operating within a No-Discharge Zone (NDZ) are completely prohibited from discharging any sewage, treated or untreated, into the waters. All vessels with an installed marine sanitation device (MSD) that are navigating, moored, anchored, or docked within a NDZ must have the MSD disabled to prevent the overboard discharge of sewage (treated or untreated) or install a holding tank. Regulations for the NDZ are contained in the U.S. Coast Pilot. Additional information concerning the regulations and requirements may be obtained from the Environmental Protection Agency (EPA) web site: http://www.epa.gov/owow/oceans/regulatory/vessel_sewage/. CAUTION – BASCULE BRIDGE CLEARANCES For bascule bridges, whose spans do not open to a full upright of vertical position, unlimited vertical clearance is not available for the entire charted horizontal clearance. RACING BUOYS Racing buoys within the limits of this chart are not shown hereon. Information may be obtained from the U.S. Coast Guard District Offices as racing and other private buoys are not all listed in the U.S. Coast Guard Light List. TIDAL INFORMATION For tidal information, see the NOS tide table publication or http://co-ops.nos.noaa.gov. ADDITIONAL INFORMATION Additional information can be obtained at www.nauticalcharts.noaa.gov IMO AMENDED TRAFFIC SEPARATION SCHEME Portions of the traffic separation scheme shown on this chart have been amended by the IMO. See IMO COLREG.2/Circ.64. Please be advised that these portions have not been revised by the United States Coast Guard and that the corresponding changes have not been updated in the Code of Federal Regulations (33 CFR part 167). There are differences between the two traffic separation schemes and caution is advised. END OF FILE
