 1.2 Structural requirements

1.2.1 For category A and B ships constructed on or after [date of entry into force] with an aggregate oil fuel capacity of less than 600 m³, all oil fuel tanks shall be separated from the outer shell by a distance of not less than 0.76 m. This provision does not apply to small oil fuel tanks with a maximum individual capacity not greater than 30 m³

1.2.2 For category A and B ships constructed on or after [date of entry into force] of less than 600 tonnes deadweight, all cargo tanks constructed and utilized to carry oil shall be separated from the outer shell by a distance of not less than 0.76 m.

1.2.3 For category A and B ships constructed on or after [date of entry into force] all oil residue (sludge) tanks and oily bilge water holding tanks shall be separated from the outer shell by a distance of not less than 0.76 m. This provision does not apply to small tanks with a maximum individual capacity not greater than 30 m³.

_{* It should be noted that parts II-A and II-B are expected to be adopted by MEPC 68 (11 to 15 May 2015).}

Chapter 2 - Control of Pollution by Noxious Liquid Substances in Bulk

2.1 Operational requirements

2.1.1 In Arctic waters any discharge into the sea of noxious liquid substances, or mixtures containing such substances, shall be prohibited.

2.1.2 Operation in polar waters shall be taken into account, as appropriate, in the Cargo Record Book, the Manual and the shipboard marine pollution emergency plan for noxious liquid substances or the shipboard marine pollution emergency plan as required by MARPOL Annex II.

2.1.3 For category A and B ships constructed on or after [date of entry into force] the carriage of noxious liquid substances (NLS) identified in chapter 17, column e, as ship type 3 or identified as NLS in chapter 18 of the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk in cargo tanks of type 3 ships shall be subject to the approval of the Administration. The results shall be reflected on the International Pollution Prevention Certificate for the Carriage of Noxious Liquid Substances in Bulk or Certificate of Fitness identifying the operation in polar waters.

Chapter 4 - Prevention of Pollution by Sewage from Ships

4.1 Definitions

4.1.1 Constructed means a ship the keel of which is laid or which is at a similar stage of construction.

4.1.2 Ice-shelf means a floating ice sheet of considerable thickness showing 2 to 50 m or more above sea-level, attached to the coast.^footnote

Such discharges shall be subject to the approval by the Administration.

Chapter 5 - Prevention of Pollution by Garbage from Ships

5.1.1 Ice-shelf means a floating ice sheet of considerable thickness showing 2 to 50 m or more above sea-level, attached to the coast^footnote.

5.1.2 Fast ice means sea ice which forms and remains fast along the coast, where it is attached to the shore, to an ice wall, to an ice front, between shoals or grounded icebergs^footnote.

 5.2 Operational requirements

5.2.1 In Arctic waters, discharge of garbage into the sea permitted in accordance with regulation 4 of MARPOL Annex V, shall meet the following additional requirements:

• .1 discharge into the sea of food wastes is only permitted when the ship is as far as practicable from areas of ice concentration exceeding 1/10, but in any case not less than 12 nautical miles from the nearest land, nearest ice-shelf, or nearest fast ice;
• .2 food wastes shall be comminuted or ground and shall be capable of passing through a screen with openings no greater than 25 mm. Food wastes shall not be contaminated by any other garbage type;
• .3 food wastes shall not be discharged onto the ice;
• .4 discharge of animal carcasses is prohibited; and
• .5 discharge of cargo residues that cannot be recovered using commonly available methods for unloading shall only be permitted while the ship is en route and where all the following conditions are satisfied:
  • .1 cargo residues, cleaning agents or additives, contained in hold washing water do not include any substances classified as harmful to the marine environment, taking into account guidelines developed by the Organization;
  • .2 both the port of departure and the next port of destination are within Arctic waters and the ship will not transit outside Arctic waters between those ports;
  • .3 no adequate reception facilities are available at those ports taking into account guidelines developed by the Organization; and
  • .4 where the conditions of subparagraphs 5.2.1.5.1, 5.2.1.5.2 and 5.2.1.5.3 of this paragraph have been fulfilled, discharge of cargo hold washing water containing residues shall be made as far as practicable from areas of ice concentration exceeding 1/10, but in any case not less than 12 nautical miles from the nearest land, nearest ice shelf, or nearest fast ice.

5.2.3 Operation in polar waters shall be taken into account, as appropriate, in the Garbage Record Book, Garbage Management Plan and the placards as required by MARPOL Annex V.]
