MO’s Working Group on the Evaluation of Safety and Pollution Hazards of Chemicals (ESPH 19), meeting at IMO Headquarters from 21 to 25 October, 2013, has agreed to classify high-viscosity PIB (Polyisobutylene) as category X for carriage by ship, thereby prohibiting the discharge of cargo residues into the sea. The categorization and carriage requirements for high-viscosity PIB will be included in the annual MEPC.2/Circular on the Provisional categorization of liquid substances, usually issued by IMO on 17 December each year and will be proposed for inclusion in the next edition of the International Code for the Construction and Equipment of Ships carrying Dangerous Chemicals in Bulk (IBC Code) which lists chemicals and their hazards and gives both the ship type required to carry that product as well as the environmental hazard rating. Amendments to the IBC Code are usually put forward on an annual basis so the next amendments could be considered during 2014, and if included in the next set of amendments to the IBC Code then the provisions for PIB could have an effective implementation date of 1 July 2016. Category X under the International Convention for Prevention of Pollution from Ships Annex II Regulations for the control of pollution by noxious liquid substances in bulk includes noxious liquid substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a major hazard to either marine resources or human health and, therefore, justify the prohibition of the discharge into the marine environment.
