CAUTION - USE OF RADIO SIGNALS (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 United States Coast Guard facility if telephone communication is impossible (33 CFR 153). AIDS TO NAVIGATION Consult United States Coast Guard Light List for supplemental information concerning aids to navigation. See National Geospatial-Intelligence Agency List of Lights and Fog Signals for information not included in the United States Coast Guard Light List. SUPPLEMENTAL INFORMATION Consult U.S. Coast Pilot 2 for important supplemental information. CAUTION - LARGER SCALE CHARTS Danger, Prohibited, and Restricted Areas falling within the limits of the larger scale charts are shown thereon and not repeated. CAUTION - SUBMARINE PIPELINES AND CABLES Additional uncharted submarine pipelinesand 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. CAUTION - TEMPORARY CHANGES Temporary changes or defects in aids tonavigation are not indicated. See Local Notice to Mariners. RADAR REFLECTORS Radar reflectors have been placed on manyfloating aids to navigation. Individual radar reflector identification on these aids has been omitted from this chart. 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. VESSEL TRAFFIC SERVICE Recommended traffic lanes established in Prince William Sound are shown on larger scale ENCs.
