USCG PRECAUTIONARY TRANSIT NOTIFICATION IN VICINITY OF FUKUSHIMA, JAPAN

Effective 01 August, 2013, the U. S. Coast Guard terminated its radio guard of the international voice distress, safety and calling frequency 2182 kHz and the international digital selective calling (DSC) distress and safety frequency 2187.5 kHz. Additionally, marine information and weather broadcasts transmitted on 2670 kHz will terminate concurrently. See the safety alert. Note that these frequencies are still available and in use, notwithstanding the Coast Guard's termination of the radio guard. Please contact us if you have any questions.



In response to the situation at the Fukushima Nuclear Power Plant in Japan, the U.S. Coast Guard recommends, as a precaution, that vessels avoid transiting within 50 miles (43 nautical miles/80 kilometers) of the Fukushima Nuclear Power Plant (37░N, 141░01'E). áMariners are advised that this recommendation should be considered a minimum distance. áPrudent route planning should incorporate prevailing and changing wind and weather conditions, in addition to the other precautionary measures.

In the event a vessel bound for a U.S. port transits within the 50 mile (43 nautical miles/80 kilometers) cautionary area, the U.S. Coast Guard recommends the vessel's master submit transit information, including the date and total time within the cautionary area, to the cognizant U.S. Coast Guard Captain of the Port using the comment block in the routine submittal of their 96-hour Advanced Notice of Arrival.

The U.S. Coast Guard will provide an updated notice as additional guidance becomes available. áMariners should keep abreast of information being provided by the government of Japan relating to any further potential impacts.
