1 A Party shall endeavour to notify mariners of
areas under their jurisdiction where ships should not uptake Ballast
Water due to known conditions. The Party shall include in such notices
the precise coordinates of the area or areas, and, where possible,
the location of any alternative area or areas for the uptake of Ballast
Water. Warnings may be issued for areas:
-
.1 known to contain outbreaks, infestations, or
populations of Harmful Aquatic Organisms and Pathogens (e.g., toxic
algal blooms) which are likely to be of relevance to Ballast Water
uptake or discharge;
-
.2 near sewage outfalls; or
-
.3 where tidal flushing is poor or times during
which a tidal stream is known to be more turbid.
2 In addition to notifying mariners of areas in
accordance with the provisions of paragraph 1, a Party shall notify
the Organization and any potentially affected coastal States of any
areas identified in paragraph 1 and the time period such warning is
likely to be in effect. The notice to the Organization and any potentially
affected coastal States shall include the precise coordinates of the
area or areas, and, where possible, the location of any alternative
area or areas for the uptake of Ballast Water. The notice shall include
advice to ships needing to uptake Ballast Water in the area, describing
arrangements made for alternative supplies. The Party shall also notify
mariners, the Organization, and any potentially affected coastal States
when a given warning is no longer applicable.
