The Sea Pollution (Amendment) Act 1999 gives effect in Irish law to the International Maritime Organisation's Oil Pollution Preparedness, Response and Co-operation Convention. The IMO, in March 2000, adopted a protocol to OPRC, providing for a response measure similar to those for oil pollution to apply in respect of hazardous and noxious substances. The Sea Pollution (Miscellaneous Provisions) Bill 2003 gives effect to the protocol. Building on the arrangements adopted in respect of oil tankers and vessels carrying hazardous substances, a convention was adopted at international level in March 2001 in relation to civil liability in respect of pollution from spills of bunker oil, which is oil that is carried other than as cargo. The miscellaneous provisions Bill gives effect to that convention. The International Convention on the Control of Harmful Anti-Fouling Systems on Ships 2001, the AFS Convention, was adopted by the IMO in October 2001 and the miscellaneous provisions Bill also gives effect thereto. The Sea Pollution Act 1991 provides for the prevention of pollution of the sea by oil or other substances and gives effect to the International Convention for the Prevention of Pollution from Ships, done at London on 2 November 1973, as amended by the protocol done at London on 17 February 1978, also known as the MARPOL Convention. Regulations covering the various sources of ship-generated pollution were originally contained in the five annexes to the convention.
