1.Member States shall take the necessary measures to ensure that transformers containing more than 0,05 % by weight of PCBs are decontaminated under the following conditions:
(a)the objective of the decontamination must be to reduce the level of PCBs to less than 0,05 % by weight and, if possible, to no more than 0,005 % by weight;
(b)the replacement fluid not containing PCBs must entail markedly lesser risks;
(c)the replacement of the fluid must not compromise the subsequent disposal of the PCBs;
(d)the labelling of the transformer after its decontamination must be replaced by the labelling specified in the Annex hereto.
2.By way of derogation from Article 3, Member States shall ensure that transformers the fluids in which contain between 0,05 % and 0,005 % by weight of PCBs are either decontaminated under the conditions laid down in paragraph 1 (b) to (d) or disposed of at the end of their useful lives.
