Disposing of polychlorinated biphenyls (PCBs)

You must dispose of PCBs and materials that contain PCBs as a persistent organic pollutant and hazardous waste.

That means you can either:

• dispose of the PCBs or equipment in a way that destroys the PCB content 
• apply to permanently store the equipment underground if you cannot destroy the PCB content

You must keep records to show that you disposed of the PCBs by one of these two methods.

Transformer disposal and decontamination

You can continue to hold transformers that contain fluids containing more than 0.005% but no more than
0.05% by weight of PCBs, and a total volume of more than 0.05dm3 of PCBs until 31 December 2025.

After this date they must be taken out of use and disposed of, or decontaminated as soon as possible.

Tell us about your plans to meet this deadline and how you will demonstrate you have implemented it
successfully.
