AIDS TO NAVIGATION
  CAUTION:   Temporary changes or defects in aids to navigation are not indicated on this 
  chart.  See Notice to Mariners.
  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.
  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.
  Consult U.S. 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 U.S. Coast Guard Light List.

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.

MINERAL DEVELOPMENT STRUCTURES:  Obstruction lights and sound (fog) signals are required 
for fixed mineral development structures shown on this electronic navigation chart, subject 
to approval by the District Commander, U.S. Coast Guard (33 CFR 67).

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).

VESSELS TRANSITING:  The U.S. Coast Guard and Pacific States/British Columbia Oil Spill 
Task Force endorse a system of voluntary measures and minimum distances from shore for 
certain commercial vessels transiting along the coast anywhere between Cook Inlet, Alaska, 
and San Diego, California. See U.S. Coast Pilot 7, Chapter 3 for details.

NATIONAL MARINE SANCTUARIES & MARINE PROTECTED NOTE: 
 National Marine Sanctuaries are protected areas, administered by NOAA, which contain sensitive and
diverse natural and cultural resources. These areas are particularly sensitive to environmental damage such as
spills of oil and other hazardous materials, discharges and groundings. Exercise particular caution and follow
applicable Sanctuary regulations when transiting these areas. A full description of Sanctuary regulations may be
found in 15 CFR 922 and in the U.S. Coast Pilot. A full description of the federal regulations governing the Marine
Protected Areas located within Channel Islands National Marine Sanctuary boundaries may be found in 15 CFR  
922 and 50 CFR 660. A full description of the state regulations governing the Marine Protected Areas located
within Channel Islands National Marine Sanctuary boundaries may be found in Title 14 California Code of
Regulations (CCR) section 632.
