Pollution Categorisation System Category X Major Hazard prohibition of discharge into the environment Category Y Hazard limitation on quality and quantity of discharge into environment Category Z Minor hazard less stringent restrictions on quality and quantity of discharge Other Substances (OS) Present no harm and not subject to any of the requirements of the Annex 13 Some of the Other Substances Apple Juice Clay Slurry Coal Slurry Glucose Solution Hydrolised Vegetable Protein Kaolin Slurry Molasses Water Lecithin Sorbitol solution 14 Lists of Products Products evaluated under Annex II were originally listed in Appendices II and III to Annex II. Since the early 1990 s editions of the Convention have not included these lists since pollution categories are indicated in the appropriate column of chapters 17 and 18 of the IBC Code 15 5
Cargoes that are subject to the IBC Code (i.e. that must be carried on chemical tankers) are listed in Chapter 17 of the Code, together with all necessary carriage requirements 16 Cargoes that have been evaluated and found not to require carriage in chemical tankers are listed in Chapter 18 of the Code. Such cargoes are mostly subject to MARPOL Annex II, and vessels which carry them must comply with the relevant provisions 17 Products that have been provisionally assessed or that have been fully evaluated and are awaiting entry into the next edition of the IBC Code can be found in List 1 of the MEPC.2/Circular. 18 6
MEPC.2/Circ. Issued each year in December Contains a number of Annexes with additional information regarding various aspects of the carriage of NLS 19 Annex 1:List 1: Pure or technically pure products; Annex 2: List 2: Pollutant only mixtures containing at least 99% by weight of components already assessed by IMO; Annex 3: List 3: (Trade-named) mixtures containing at least 99% by weight of components already assessed by IMO, presenting safety hazards; Annex 4: List 4: Pollutant only mixtures containing one or more components, forming more than 1% by weight of the mixture, which have not yet been assessed by the IMO 20 Annex 5: List 5: Substances not shipped in pure form but as components in mixtures; Annex 6: Synonyms for vegetable oils; Annex 7: Country abbreviations; Annex 8: Tripartite contact addresses; Annex 9: Manufacturers authorized to conduct pollutantonly assessments by calculation; Annex 10: Cleaning additives; and Annex 11: Recognised bio-fuels 21 7
NLS divided into categories according to the level of threat they pose the environment Conditions established for each category under which discharge into sea is permitted Stripping Limits defined for each category Procedures and Arrangements (P & A) Manuals define how the vessel will comply 22 Discharge Below the Waterline The underwater discharge outlet (or outlets) shall be located within the cargo area in the vicinity of the turn of the bilge and should be so arranged as to avoid the re-intake of residue/water mixtures by the ship s seawater intakes. 23 The underwater discharge outlet arrangement shall be such that the residue/water mixture discharged into the sea will not pass through the ship s boundary layer 24 8
25 Prewash Ashore The most polluting products are not allowed to be discharged into the marine environment under any circumstances Upon completion of unloading a prewash must be performed, with washings discharged to a reception facility ashore 26 Wash water must be discharged to a reception facility until the concentration of the substance in the effluent to the facility is at or below the levels specified Annex II defines how this is to be achieved 27 9
Stripping Limits Vessels must be provided with pumping and piping systems that enable them to strip tanks to levels defined in regulation 12 of Annex II 28 Regulation 12 Pumping, piping, unloading arrangements and slop tanks 1 July 1986 1 January 2007 X, Y<300 Litres Z<900 Litres X, Y<100 Litres Z<300 Litres X, Y and Z <75 Litres Underwater Discharge Outlet Slop tanks (cargo tanks) 29 4 Category system ALL new ships Existing IBC Existing BCH Other ships (existing) X 75 litres + PW 100 litres + 50 ltr tolerance + 300 litres + 50 ltr tolerance + NO TRANSPORT PW PW Y 75 litres (PW + ES) 100 litres + 50 ltr tolerance 300 litres + 50 ltr tolerance NO TRANSPORT (PW + ES) (PW OR ES) Z 75 litres 300 litres + 50 ltr tolerance 900 litres + 50 ltr tolerance TO THE MOST EXTENT POSSIBLE NO quantity NO quantity NO quantity NO quantity OS NO quality LIMITATION NO quality LIMITATION NO quality LIMITATION NO quality LIMITATION 30 10

IBC Code International standard for the safe carriage by sea in bulk of dangerous and noxious liquid substances Mandatory under both SOLAS and MARPOL 34 applies to ships, regardless of size, including those of less than 500 gt, engaged in the carriage of bulk cargoes of dangerous chemicals or noxious liquid substances (NLS), other than petroleum 35 The IBC Code prescribes carriage requirements for each individual cargo that is subject to the Code in respect of a variety of factors including, inter alia:- SHIP TYPE and other specific requirements Tank venting open or controlled Tank environmental control drying, inerting, padding Electrical Equipment according to surface temperature and type of gases for which it is suitable Gauging open or restricted Fire Protection type of foam, powder or spray Special requirements chapter 15 lays out particular special requirements which may apply to certain cargoes 36 12
Each tanker is assigned a Ship Type according to the degree of hazards of the products to be carried 37 Ship Types are assigned according to the cargoes the ship will carry, taking into account: the hazard they may present to the environment other hazardous properties, including: flammability toxicity corrosivity reactivity 38 Ship Types are defined according to: cargo tank location ability to withstand collision or grounding damage 39 13
Ship Type 1 a chemical tanker intended to transport chapter 17 products with very severe environmental and safety hazards which require maximum preventive measures to preclude an escape of such cargo. Must be capable of sustaining damage throughout the entire length of the vessel 40 Ship Type 2 a chemical tanker intended to transport chapter 17 products with appreciably severe environmental and safety hazards which require significant preventive measures to preclude an escape of such cargo. Must be able to sustain damage: more than 150 m in length: anywhere in its length. 150 m in length or less: anywhere except involving either of the bulkheads bounding a machinery space located aft. 41 Ship Type 3 chapter 17 products with sufficiently severe environmental and safety hazards which require a moderate degree of containment to increase survival capability in a damaged condition. Must be able to sustain damage: more than 225 m in length: anywhere 125 m to 225 m in length: anywhere except involving either of the bulkheads bounding a machinery space located aft. below 125 m in length: anywhere except involving damage to the machinery space when located aft. 42 14
