1.1 The International Convention for the Control
and Management of Ships' Ballast Water and Sediments, 2004 (BWM Convention) regulates the transfer of harmful
aquatic organisms and pathogens from ships' ballast water and sediments.
This Convention gives a Party, individually or jointly with other
Parties, the right to introduce additional measures (e.g., immediate
control measures in emergency or epidemic situations) in accordance
with regulation C-1, taking into
account the Guidelines for additional measures regarding ballast water
management including emergency situations (G13).
1.2 The technical recommendations contained in
this document provide guidance for use in emergency/epidemic situations,
when specific and rapid measures need to be taken to prevent major
threats and damages from the transfer of harmful aquatic organisms
and pathogens through ballast water. This guidance would assist a
Party to rapidly identify appropriate measure(s) whenever emergency
situations occur in relation to ballast water operations. Countries
should analyse the risks and nature of the threats that are posed
by ballast water transfer in their waters and develop the structure
that best suits them, taking into consideration the specific characteristics
of the ecosystems involved and the resources available to them. This
Guidance is not intended as a mandatory model or a set structure to
be followed during potential or actual emergencies.
1.3 Examples of when an emergency situation may
arise include:
–
|
the introduction of organisms that may
cause significant damage to the human population, human food supply,
industry or other economic activities, or an area's natural biodiversity;
or
|
–
|
the threat of such an introduction
through ballast water from a vessel that has come from another emergency
area.
|
1.4 Appropriate and efficiently applied emergency
measures are vital to minimizing both the potential damage in an affected
area and the risk of other areas being affected. Emergency situations
relating to environmental, economic and human health issues may represent
an immediate threat to a particular location, or to neighbouring locations,
as well as areas to be visited by vessels carrying ballast water from
this location.
1.5 Rapid and correct handling of the emergency
will also affect the likelihood of normalizing the situation in the
longer term. It should be noted, however, that the priority for emergency
situations should be the prevention of introduction of harmful aquatic
organisms and pathogens. Once a relevant species has gained a foothold
in an area, it will be very difficult to eradicate it without causing
additional significant environmental or habitat damage. Often terrestrial
eradication measures do not transfer easily into the coastal, tidal
and marine environment.
