Persistent Organic Pollutants (Amendment) Regulations 2024

Considered in Grand Committee

Moved by

That the Grand Committee do consider the Persistent Organic Pollutants (Amendment) Regulations 2024.

My Lords, this instrument adds three substances, UV-328, dechlorane plus and methoxychlor, to the assimilated persistent organic pollutants—or POPs—regulation in response to the adoption of these three substances as POPs under the United Nations Stockholm convention. The UK is a party to the convention and is therefore obligated to reflect in UK law the listing of POPs under the convention.

In addition, this instrument makes a number of other technical changes to the annexes of the POPs regulation. These include changes to waste concentration limits, specific exemptions and unintentional trace contaminant levels—or UTCs—for some POPs. The amendments, in brief, update and clarify the way that some articles, substances or mixtures containing some POPs can be used, manufactured, placed on the market or disposed of.

This legislative change is permitted by use of the powers available within Articles 7, 15 and 18 of the assimilated EU regulation on POPs. We have worked with the devolved Administrations on this instrument.

POPs are substances recognised as being particularly dangerous to the health of humans, wildlife and the environment. This instrument preserves and adds to the current regime for managing, restricting or eliminating POPs in the UK. Some of the regulations in this amending instrument are needed to implement the UK’s commitments under the United Nations Stockholm convention on POPs. The majority of amendments are informed by updates to the Stockholm convention and, in some cases, following updates made to the Basel Convention guidance on the management of POPs waste, and following consultation.

Let me turn now to the detail of the instrument. At the 11th meeting of the conference of the parties held last year, a decision was adopted to add three new substances called UV-328, dechlorane plus and methoxychlor to the list of substances for global elimination under the convention. This decision was communicated to parties by the UN depository in February 2024. This instrument adds these new POPs to the list of substances that are prohibited by law from being manufactured, placed on the market and used in GB.

Secondly, the instrument provides some exemptions from the prohibitions by allowing the unintentional presence of these three substances at trace levels. These limits define the concentrations at which UV-328, dechlorane plus 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 conference of the parties to the Stockholm convention.

This instrument will make a number of further changes to Annexe 1 of the POPs regulation, including the addition of a UTC level for two POPs that are already prohibited in GB. It will also make amendments to the UTC limits and specific exemptions listed for the substance PFOA, including a provision to phase out or remove exemptions which are no longer required, and tighten the requirements regarding a specific exemption for use of PFOA in PTFE micropowders.

My Lords, I thank the Minister for her introduction. I understand why the changes to these regulations have been brought forward, in order to take account of changes to scientific and technical progress, and to stay in line with amendments to the Stockholm Convention on Persistent Organic Pollutants. The UK is a party to this critical convention, and it is important that we ensure that the country and the public as a whole are protected from toxic substances.

The four qualifications for substances being classed as a POP are that they are persistent, toxic, bioaccumulative and subject to long-range environmental transport. This SI makes amendments to the lists of substances in annexe A of the convention. The SI lists these substances as UV 328, dechlorane plus and methoxychlor. The instrument also lists unintentional trace contaminant UTC limits for those substances, and adds two new POPs to this category which are already prohibited under the ordinary POPs regulations: hexachlorobenzene and pentachlorophenol. There are other substances named which are covered by the SI, but I readily admit that, not being a chemist or a scientist, some of the detail is outside my experience.

Paragraph 5.8 of the Explanatory Memorandum refers to certain POP waste being permanently stored in designated hazardous waste landfill or salt mines when destruction is not the environmentally preferred option, as the Minister referred to. I assume that the salt mines referred to will be depleted and never brought back into use. Can she provide reassurance on this matter?

The SI also expands the scope for three offences under the POP regulations of 2007, but neither the Explanatory Memorandum nor the SI says what the penalties for the offences are. Can the Minister provide clarification on this?

My Lords, I also thank the Minister for bringing these regulations to the Committee and for opening this debate. We wholeheartedly support the Government in their work to build on our strong track record of tackling pollution and effectively managing substances that are persistent pollutants.

These regulations amend EU regulation 2019/1021 of the European Parliament and Council on persistent organic pollutants to alter the rules for the management of certain substances under the persistent pollutant regime. It is important that the Government have the right rules in place for the management of substances that can pollute our environment over many years because they break down slowly. We welcome these regulations.

What assessment have the Government made of our pollutant regulation regime since they took office? Can the Minister confirm whether they have identified any areas of pollution where Ministers intend to change our existing regime or whether they feel that it is currently satisfactory? Can she give some idea of current trace levels of these persistent pollutants and how they compare with the limits in this instrument? Further to that, can she reassure this Committee that these new limits will ensure that none of these pollutants can be intentionally introduced in manufacturing, except for the specified products?

The Minister set out exemptions for the use of these chemicals. Can she explain why these exemptions are necessary given the awful long-term consequences of allowing any production of these chemicals and compounds? Finally, what steps are the Government taking to monitor the levels of “forever chemicals” in our environment to ensure that these levels are within a safe range?

My Lords, I thank the noble Lord, Lord Roborough, and the noble Baroness, Lady Bakewell of Hardington Mandeville, for their support for this SI. It is very much appreciated. This was a small but perfectly formed debate on something complex but nevertheless important, because these draft regulations ensure that existing legal provisions for the prohibition and restriction of the manufacture, placing on the market and use of POPs will be extended to the new substances, and they also amend the annexes.

PFAS chemicals were recently raised as part of debates on the Water (Special Measures Bill)—the noble Lord, Lord Roborough, referred to this. I recognise the concerns, particularly about PFAS. I know that the Rivers Trust did a good but concerning report on this earlier in the year—that was launched here in the House of Lords, and I went to it. There is currently a lot of research on PFAS to improve our understanding. We are also looking at whether we should restrict PFAS in firefighting foams, as well as further restrictions for consumer and industrial uses. The instrument includes the introduction of a limit specifically targeted at PFOA, which is a type of PFAS in those foams. This will be designed to ensure environmentally sound disposal of any remaining stockpiles of these foams. Quite a lot of work is going on PFAS because we are very much aware of the problems in that area.

On chemicals included in the EIP, the Government have launched a rapid review to look at the legally binding targets within the environmental improvement plan, including how we accelerate progress to hit our international commitments of protecting 30% of the UK’s land and sea by 2030—the 30 by 30 target. So that is one thing that we are looking at, and we will use that as an opportunity to review some of the areas raised today.

The noble Baroness, Lady Bakewell, asked about waste. As I said, waste containing POPs above the specified waste concentration limits must be diverted from landfill or recycling because it is important that they are destroyed—for example, through high-temperature incineration. The noble Baroness asked about salt mines in particular. I probably need to get back to her on that and her question about penalties. I have not got the detail on salt mines in front of me, and there is a range of options for penalties, so it might be helpful to lay that out in a letter to the noble Baroness and share it with the noble Lord, Lord Roborough. Have I missed anything? It was such a short debate.

Has the Minister any more information on trace limits as a result of historic manufacturing of these persistent pollutants, compared to the limits in the instruments? That would be interesting and I completely understand if that might need a letter rather than an answer now.

That is an extremely important point, and it is probably part of the research currently being carried out in this sphere. I will check and we will get back to anyone with any outstanding questions.

Motion agreed.
