Whole document
Regulation 2 Application
(1) Unless expressly provided otherwise the provisions of this Annex
shall apply to all ships carrying noxious liquid substances in bulk.
(2) Where a cargo subject to the provisions of Annex I of the present
Convention is carried in a cargo space of a chemical tanker, the
appropriate requirements of Annex I of the present Convention shall also
apply.
(3) Regulation 13 of this Annex shall apply only to ships carrying
substances which are categorized for discharge control purposes in
Category A, B or C.
(4) For ships constructed before 1 July 1986, the provisions of
regulation 5 of this Annex in respect of the requirement to discharge
below the waterline and maximum concentration in the wake astern of the
ship shall apply as from 1 January 1988.
(5) The Administration may allow any fitting, material, appliance or
apparatus to be fitted in a ship as an alternative to that required by
this Annex if such fitting, material, appliance or apparatus is at least
as effective as that required by this Annex. This authority of the
Administration shall not extend to the substitution of operational methods
to effect the control of discharge of noxious liquid substances as
equivalent to those design and construction features which are prescribed
by regulations in this Annex.
(6) The Administration which allows a fitting, material, appliance or
apparatus as alternative to that required by this Annex, under paragraph
(5) of this regulation, shall communicate to the Organization for
circulation to the Parties to the Convention, particulars thereof, for
their information and appropriate action, if any.
Regulation 3 Categorization and listing of noxious liquid sub-stances
(1) For the purpose of the regulations of this Annex, noxious liquid
substances shall be divided into four categories as follows:
(a) Category A: Noxious liquid substances which if discharged into
the sea from tank cleaning or deballasting operations would present a
major hazard to either marine resources or human health or cause serious
harm to amenities or other legitimate uses of the sea and therefore
justify the application of stringent anti-pollution measures.
(b) Category B: Noxious liquid substances which if discharged into
the seat from tank cleaning or deballasting operations would present a
hazard to either marine resources or human health or cause harm to
amenities or other legitimate uses of the sea and therefore justify the
application of special anti-pollution measures.
(c) Category C: Noxious liquid substances which if discharged into
the sea from tank cleaning or deballasting operations would present a
minor hazard to either marine resources or human health or cause minor
harm to amenities or other legitimate uses of the sea and therefore
require special operational conditions.
(d) Category D: Noxious liquid substances which if discharged into
the sea from tank cleaning or deballasting operations would present a
recognizable hazard to either marine resources or human health or cause
minimal harm to amenities or other legitimate uses of the sea and
therefore require some attention in operational conditions.
(2) Guidelines for use in the categorization of noxious liquid
substances are given in appendix I to this Annex.
(3) The list of noxious substances carried in bulk and presently
categorized which are subject to the provisions of this Annex is set out
in appendix II to this Annex.
(4) Where it is proposed to carry a liquid substance in bulk which has
not been categorized under paragraph (1) of this regulation or evaluated
as referred to in regulation 4 (1) of this Annex, the Governments of
Parties to the Convention involved in the proposed operation shall
establish and agree on a provisional assessment for the proposed operation
on the basis of the guidelines referred to in paragraph (2) of this
regulation. Until full agreement between the Governments involved has been
reached, the substance shall be carried under the most severe conditions
proposed. As soon as possible, but not later than 90 days after its first
carriage, the Administration concerned shall notify the Organization and
provide details of the substance and the provisional assessment for prompt
circulation to all Parties for their information and consideration. The
Government of each Party shall have a period of 90 days in which to
forward its comments to the Organization, with a view to the assessment of
the substance.
Regulation 4 Other liquid substances
(1) The substances listed in appendix III to this Annex have been
evaluated and found to fall outside the Categories A, B, C and D, as
defined in regulation 3 (1) of this Annex because they are presently
considered to present no harm to human health, marine resources,
amenities or other legitimate uses of the sea, when discharged into the
sea from tank cleaning or deballasting operations.
(2) The discharge of bilge or ballast water or other residues or
mixtures containing only substances listed in appendix III to this Annex
shall not be subject to any requirement of this Annex.
(3) The discharge into the sea of clean ballast or segregated ballast
shall not be subject to any requirement of this Annex.
