Hazardous property code
HP POP Contains regulated POPs above legal limits
Waste that contains regulated persistent organic pollutants (POPs) at concentrations exceeding the legal limits set out in Annex IV of the POPs Regulation, and is therefore classified as hazardous.
HP POP applies where a waste contains regulated persistent organic pollutants at concentrations above the limits set for them. Unlike the other hazard properties, which describe an effect, this one is about named substances measured against published limits.
It changes what can be done with the waste as well as how it is documented: waste above those limits has to be treated so the POP content is destroyed or irreversibly transformed. The POPs present are declared as components with their concentrations, using DEFRA's POP codes.

EWC codes that commonly carry this hazard property
6 entries from the UK List of Wastes.
These are EWC entries that typically carry this hazard property, not a determination that any particular load does. Under WM3, whether a hazard property applies depends on the substances actually present and their concentrations — the producer is responsible for assessing each consignment.
- 03 02 02organochlorinated wood preservativeshazardousOrganochlorinated wood preservatives (e.g. pentachlorophenol) — acutely toxic, carcinogenic and ecotoxic; PCP is a listed POP.
- 13 01 01hydraulic oils, containing pcbshazardousPCB-containing hydraulic oils — carcinogenic and ecotoxic; PCBs are Stockholm-listed POPs.
- 13 03 01insulating or heat transmission oils containing pcbshazardousPCB-containing insulating / heat-transmission oils — carcinogenic and ecotoxic; PCBs are listed POPs.
- 16 02 09transformers and capacitors containing pcbshazardousPCB-containing transformers and capacitors — carcinogenic and ecotoxic; PCBs are listed POPs.
- 16 02 10discarded equipment containing or contaminated by pcbs other than those mentioned in 16 02 09hazardousEquipment containing or contaminated by PCBs — carcinogenic and ecotoxic; PCBs are listed POPs.
- 17 09 02construction and demolition wastes containing pcb (for example pcb-containing sealants, pcb-containing resin-based floorings, pcb-containing sealed glazing units, pcb-containing capacitors)hazardousC&D waste containing PCBs — carcinogenic and ecotoxic; PCBs are listed POPs.

Recording HP POP on real paperwork?
Waste carrying HP POP is hazardous, so it moves on a Hazardous Waste Consignment Note rather than a standard Waste Transfer Note. Our free generator produces a compliant PDF in under a minute.
