These Regulations relate, in respect of Scotland, to Council Directive 96/59/EEC on the disposal of polychlorinated biphenyls and polychlorinated terphenyls ( PCBs ). They are made for the purpose of implementing the provisions of the Directive which require decontamination or disposal of PCBs and equipment containing them and the associated provisions for inventories, labelling and monitoring. They are additional to the existing relevant requirements of the waste management licensing regime under the Environmental Protection Act 1990. They provide, among other things, for registration of persons who are in possession of PCBs, including any used PCBs or of any equipment.
