ANNEX Summary, for reference purposes, of the Marpol 73/78 discharge regulations relating to discharges of oil and noxious liquid substances, as referred to in Article 2.2

Part I: Oil (Marpol 73/78, Annex I)

For the purposes of Marpol 73/78 Annex I, ‘oil’ means petroleum in any form including crude oil, fuel oil, sludge, oil refuse and refined products (other than petrochemicals which are subject to the provisions of Marpol 73/78 Annex II) and ‘oily mixture’ means a mixture with any oil content.

Excerpts of the relevant provisions of Marpol 73/78 Annex I:

• Regulation 9: Control of discharge of oil

  1.

  Subject to the provisions of Regulations 10 and 11 of this Annex and paragraph 2 of this Regulation, any discharge into the sea of oil or oily mixtures from ships to which this Annex applies shall be prohibited except when all the following conditions are satisfied:

Part II: Noxious liquid substances (Marpol 73/78 Annex II)

Excerpts of the relevant provisions of Marpol 73/78 Annex II:

• Regulation 3: Categorisation and listing of noxious liquid substances

  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 sea 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 recognisable 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.
