CHAPTER 1 – GENERAL

Regulation 1 – Definitions

1 A new paragraph 23 is added as follows:

  • "23 Persistent floater means a slick forming substance with the following properties:

    • - Density: ≤ sea water (1025 kg/m3 at 20°C);

      - Vapour pressure: ≤ 0.3 kPa;

      - Solubility: ≤ 0.1% (for liquids) ≤ 10% (for solids); and

      - Kinematic viscosity: > 10 cSt at 20°C."

CHAPTER 5 – OPERATIONAL DISCHARGES OF RESIDUES OF NOXIOUS LIQUID SUBSTANCES

Regulation 13 – Control of discharges of residues of noxious liquid substances

2 A new paragraph 7.1.4 is inserted after existing paragraph 7.1.3 as follows:

  • "7.1.4 For substances assigned to category Y that are persistent floaters with a viscosity equal to or greater than 50 mPa·s at 20ºC and/or with a melting point equal to or greater than 0ºC, as identified by '16.2.7' in column 'o' of chapter 17 of the IBC Code, the following shall apply in the areas in paragraph 9:

    • .1 a prewash procedure as specified in appendix VI to this annex shall be applied;

    • .2 the residue/water mixture generated during the prewash shall be discharged to a reception facility at the port of unloading until the tank is empty; and

    • .3 any water subsequently introduced into the tank may be discharged into the sea in accordance with the discharge standards in regulation 13.2."

APPENDIX IV – STANDARD FORMAT FOR THE PROCEDURES AND ARRANGEMENTS MANUAL

Section 4 – Procedures relating to the cleaning of cargo tanks, the discharge of residues, ballasting and deballasting

4 Paragraph 4.4.5 is replaced by the following:

  • ".5 Persistent floaters with a viscosity equal to or greater than 50 mPa·s at 20ºC and/or a melting point equal to or greater than 0ºC

    This section should contain instructions on how to deal with tank washings of substances identified by the presence of '16.2.7' in column 'o' of chapter 17 of the IBC Code and the latest version of the MEPC.2/Circular, when operating in the areas specified in regulation 13.9 of Annex II."

Addendum A – Flow diagrams – Cleaning of cargo tanks and disposal of tank washings/ballast containing residues of category X, Y and Z substances

5 A new Note 4 is inserted after existing Note 3 as follows:

  • "Note 4: Within the areas specified in regulation 13.9 of Annex II, regulation 13.7.1.4 applies to substances that are identified by '16.2.7' in column 'o' of chapter 17 of the IBC Code."

APPENDIX VI – PREWASH PROCEDURES

6 A new section C is added after existing paragraph 21 as follows:

  • "C For all ships

    Prewash procedures for persistent floaters to which regulation 13.7.1.4 of Annex II of MARPOL applies

    Persistent floaters with a viscosity equal to or greater than 50 mPa·s at 20ºC and/or a melting point equal to or greater than 0ºC, shall be treated as solidifying or high-viscosity substances for the purposes of the prewash.

    Where it is determined that the use of small amounts of cleaning additives would improve and maximize the removal of cargo residues during a prewash, then this should be done in consultation and with prior agreement from the reception facility."
