AIDS TO NAVIGATION
  CAUTION:  Limitations on the use of certain 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: Temporary changes or defects in aids to navigation are not indicated on this chart.
  See Notice to Mariners.
  
RADAR REFLECTORS:  Radar reflectors have been placed on many floating aids to navigation.  
Individual radar reflector identification on these aids has been omitted from the light 
list and will not be reflected in the objects or attribution of this electronic navigation 
chart.
Consult U.S. Coast Guard Light List for supplemental information concerning aids to 
navigation.

AUTHORITIES:  Hydrography and Topography by the National Ocean Service, Coast Survey, 
with additional data from the U.S. Army Corps of Engineers, U.S. Geological Survey, and 
U.S. Coast Guard.

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.

NOAA VHF-FM WEATHER BROADCASTS:  The National Weather Service stations listed below provide 
continuous marine weather broadcasts.  The range of reception is variable, but for most 
stations is usually 20 to 40 miles from the antenna site.
Point Arena /Ukiah, CA	       	KIH-30  		162.55 MHz WX1
Mt Pise, CA 	                KHB-49  		162.40 MHz WX2
Mt Umunhum, CA			KEC-49		        162.55 MHz WX1
Mt Umunhum, CA (Marine only)	WWF-64		        162.45 MHz WX5

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).

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.
