I will do my best—by the end of this, I’ll have nailed it.
These limits define the concentrations at which UV-328, dechlorane plus—I got that one—and methoxychlor can lawfully be found in a substance, article or mixture, where they are unintentionally present and found in minimal amounts. Dechlorane plus and UV-328 will also be listed alongside time-limited exemptions for their continued use in specific circumstances. These exemptions are available following agreement by the Stockholm convention’s conference of the parties.
This instrument will make a number of further changes to annex 1 of the POPs regulation, including the addition of a UTC level for two POPs already prohibited in Great Britain. It will also make amendments to the UTC limits and specific exemptions listed for the substance perfluorooctanoic acid, or PFOA, including a provision to phase out or remove exemptions that are no longer required, and the tightening of the requirements regarding a specific exemption for use of PFOA in polytetra-fluoroethylene, or PTFE, micropowders.
Annexes 4 and 5 of the POPs regulation relate to the treatment of waste containing POPs. This instrument will add or update waste concentration limits for several POPs. In practice, those limits specify the concentration at which waste containing POPs must be diverted from landfill to high-temperature incineration or other appropriate disposals, to ensure that the POPs content is appropriately destroyed. Importantly, that includes the introduction of a limit specifically targeted at firefighting foam mixtures containing PFOA—a substance in the poly and perfluoroalkyl, or PFAS, group of chemicals—to ensure the environmentally sound disposal of any remaining stockpiles of these foams.
Finally, this instrument will update the maximum concentration limits for a number of POPs and add decabromodiphenyl ether, or decaBDE, a brominated flame retardant, to the list of polybrominated diphenyl ethers, or PBDEs, in annex 5 of the POPs regulation. Maximum concentration limits set the threshold at which waste handlers can apply to permanently store certain wastes in designated landfill for hazardous waste or salt mines, where it can be demonstrated that destruction is not the environmentally preferred option. The instrument will also add two new European waste catalogue codes to this provision: one for fly ash from peat and untreated wood, and one for soil and stones.
Policy development informing this instrument was subject to a public consultation in 2023. In that consultation, we also stated our intention to prohibit the three new substances once they were adopted for listing under the convention, to implement our international obligations. There have been various opportunities, at both domestic and convention level, for UK stakeholders to submit information regarding the potential prohibition of UV-328, dechlorane plus and methoxychlor, and their potential adoption for global elimination under the Stockholm convention. A de minimis impact assessment was carried out, which concluded that there is no indication that the amendments in the instrument are expected to have an impact on businesses beyond one-off familiarisation costs, and that this instrument is not expected to disproportionally burden small businesses.
The Environment Agency is the delivery body for the POPs regulation for England; Natural Resources Wales and the Scottish Environment Protection Agency are the delivery bodies for Wales and Scotland respectively. They have been involved in the development of this instrument and have no concerns about implementation or resources. The territorial extent and application of the instrument is Great Britain. Under the Windsor frame-work, the EU POPs regulation applies in Northern Ireland. The devolved Administrations in Wales and Scotland were engaged in the development of the instrument and have consented to its being made on a GB-wide basis.
In conclusion, I emphasise that the measures in this instrument are needed, in part, to implement the requirements of the Stockholm convention by adding new POPs UV-328, dechlorane plus and methoxychlor to the list of substances prohibited in Great Britain by law. Other amendments included in the instrument ensure that the POPs regulation is adapted to scientific and technical progress in our understanding and treatment of POPs. The draft regulations will allow the UK to continue to implement the Stockholm convention requirements to prohibit, eliminate or restrict the production and use of POPs. I commend the draft regulations to the House.
