7.2.1 Any national or international legal requirements
or obligations should be considered in identifying potential sea areas
for designation under Regulation B-4.2.
7.2.2 Sea areas beyond the jurisdiction of a port
State may provide the most practical and appropriate area for ballast
water exchange. A Party should not designate ballast water exchange
areas in waters under the jurisdiction of another State, without its
agreement and consultation with adjacent and other States. Consultation
should be initiated as soon as possible in the process to facilitate
exchange of information and agreement for the designation of the ballast
water exchange area (see section 6).
