AIDS TO NAVIGATION 
Consult U.S. Coast Guard Light List for supplemental information concerning aids to navigation.


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).


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.


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.


SUPPLEMENTAL INFORMATION
Consult U.S. Coast Pilot 9 for important supplemental information.


CAUTION - TEMPORARY CHANGES 
Temporary changes or defects in aids to navigation are not indicated. See Local Notice to Mariners.


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.


ADDITIONAL INFORMATION 
Additional information can be obtained at www.nauticalcharts.noaa.gov.


NOTE A 
Navigation regulations are published in Chapter 2, U.S. Coast Pilot 9.  Additions or revisions to Chapter 2 are published in the Notice to Mariners. Information concerning the regulations may be obtained at the Office of the Commander, 17th Coast Guard District in Juneau, AK, or at the Office of the District Engineer, Corps of Engineers in Anchorage, AK. 
Refer to charted regulation section numbers.

RADAR REFLECTORS 
Radar reflectors have been placed on many floating aids to navigation. Individual radar reflector identification on these aids has been omitted from this chart.
