4.1 The objectives of these Guidelines, developed
under technical and scientific guidance, are intended to assist Governments
and appropriate authorities, ship masters, operators and owners, and
port authorities as well as other interested parties in minimizing
the risk of introducing harmful aquatic organisms and pathogens from
ships' ballast water and associated sediments while protecting ships'
safety.
4.2 The Guidelines allow port States to exempt
ships within the area under their jurisdiction from part or all of
the relevant provisions. Notwithstanding that any administration wishing
to apply restrictions to ballast water operations should still follow
these Guidelines, when developing legislation or procedures.
4.3 In order that the Guidelines be implemented
in a standard and uniform manner, all Member State Governments, ship
operators, other appropriate authorities and interested parties are
requested to apply these Guidelines.
