Proposed Salt Marshes: Pawlett Hams

Debate between Tessa Munt and Mary Creagh

Wednesday 9th October 2024 Westminster Hall

[The Parliamentary Under-Secretary of State for Environment, Food and Rural Affairs (Mary Creagh)]

It is an honour to serve under your chairmanship, Mr Twigg. I congratulate the hon. Member for Bridgwater (Sir Ashley Fox) on securing this debate and on his excellent representation of his constituents’ views here today. I begin by saying that this is the subject of a live planning case and I am sure that hon. Members will understand the limits on what I can say. However, I can assure hon. Members that I have listened carefully to the points raised, asked my officials some of the questions that they have asked, and have spent a considerable amount of time thinking about the issue. I hope that what I say will be useful to them and their constituents.

I will begin by setting out the facts of the case. The Conservation of Habitats and Species Regulations 2017 protects special areas of conservation and special protected areas. The regulations require an assessment of whether a plan or project could have an adverse impact on the integrity of a protected site. Any harm must be mitigated unless there are imperative reasons of overriding public interest and no alternative. In those cases, compensatory measures must be secured.

In this case, an acoustic fish deterrent was part of the approved mitigation for the impact of Hinckley Point C on the Severn estuary. Hinckley Point C has applied to remove the acoustic fish deterrent. That means that compensation may be needed for the loss of fish within the Severn estuary site. The species of concern are Atlantic cod, sea bass, whiting and herring.

In a pre-application consultation earlier this year, Hinckley proposed Pawlett Hams as a suitable compensatory salt marsh habitat. As the hon. Member for Bridgwater has said, Pawlett Hams was designated as part of the Bridgwater bay SSSI in 1989. It is particularly important for its network of freshwater ditches and their associate invertebrate communities—insects. Pawlett Hams is also part of the Severn estuary Ramsar—which is a wetland site—and special protection area, a European designation for bird sites. It has a triple protection.

In its response to the pre-application consultation, the Environment Agency was unable to agree with the suitability of the Pawlett Hams sites until further evidence and assessment has been completed. Hinckley approached the Environment Agency; to gently correct the hon. Member for Bridgwater, the Environment Agency did not suggest it. It is my understanding that the applicant makes a request to the regulator.

I understand that following the consultation, Hinkley Point C is investigating new locations for salt marsh creation as an alternative to Pawlett Hams. It is holding early conversations with stakeholders ahead of public consultation, as we have heard from colleagues today. Any additional sites being put forward are sites identified and selected by Hinkley Point C, not the Environment Agency. The Environment Agency agrees that the marine measures proposed are an appropriate option within a wider compensation package. It has not agreed on the scale of the measures to off-set the predicted adverse effects. To the question raised by the hon. Member for Wells and Mendip Hills (Tessa Munt), flood modelling and flood risk assessments would be required for identified sites.

[Tessa Munt]

As I understand it, the Environment Agency is helping the integrity of the seawall by building it up at Kingston Seymour, so it seems incredibly perverse that it might agree that that should change. Currently, it is making it better by creating more flood protection for the villagers in Kingston Seymour.

[Mary Creagh]

Let me come on to flood protection, and I will say something about salt marshes later. If the hon. Member is not satisfied with my response, then I am happy to write to the Environment Agency on her behalf.

The application for a material change is currently in the pre-application stage. That involves consultation and engagement with various bodies, including statutory consultees such as the Environment Agency and Natural England, which looks after our SSSIs. Those bodies will be able to provide valuable information on environmental impacts. That will include the sufficiency of the compensation package and its ability to compensate for the impact on protected fish species—let us not forget that this is about protecting the fish.

To comply with the pre-application consultation requirements under the Planning Act 2008, Hinkley Point C must carry out an appropriate consultation about any proposed changes. The decision relating to the project will ultimately be for the Secretary of State for Energy Security and Net Zero, my right hon. Friend the Member for Doncaster North (Ed Miliband) to make. I am confident that he will do so correctly, in line with the requirements of the Planning Act. However, in doing so, he will need to consider all relevant issues. They include whether the proposed compensation is required and if it is, whether it is proportionate to the detrimental impact on fish populations of not fitting the acoustic fish deterrent. The planning guidance is clear: Ministers and officials should approach all such decisions with an open mind, based on the evidence presented to them, objectively and without having or giving the appearance of having any predetermined views on the merits or otherwise of the case. I am sure that we are all, in this room, seasoned politicians in planning applications.

I cannot discuss the particular merits of this case, but I want to raise some broader points prompted by some of the issues, because I too have asked questions. I have heard what the hon. Members for Bridgwater and for Wells and Mendip Hills have asked and that has made clear that we must deliver our infrastructure goals in a way that is positive for our natural world and for our wider landscapes. If we are to meet our ambitious targets on nature restoration while accelerating to net zero, we will have to think carefully about how we use our land. That is why the forthcoming land use framework for England will consider cross-governmental issues, such as energy and food security, and how we can expand nature-rich habitats, such as wetlands, peat bogs and forests.

Spatial planning will play an important role in the delivery of the Government’s growth and clean energy missions, and the land use framework will work hand in hand with the strategic spatial energy plan. The Government will also explore the opportunities for spatial planning to support the delivery of other types of infrastructure. I recognise that in some cases the planning regime acts as a major brake on economic growth, which is why the Government will make the changes we need to forge ahead with new grid connections, roads, railways, reservoirs and other nationally significant infrastructure.

The proposed Planning and Infrastructure Bill will accelerate house building and infrastructure delivery and streamline the delivery process for critical infrastructure, including accelerating upgrades to the national grid and boosting renewable energy. That will benefit local communities, unlock delivery of our 2030 clean power mission and net zero obligations and ensure our domestic energy security. We will simplify the consenting process for major infrastructure projects and enable new and improved national policy statements to come forward. We will also establish a review process to provide the opportunity for them to be updated every five years, which will give increased certainty to developers and communities.

We are just as committed to protecting and restoring nature. In England, we are committed to halting the decline in species abundance by 2030 and reversing it by 2042. We are also committed to reducing the risk of species extinction and we will restore and create more than half a million hectares of wildlife-rich habitat by 2042. Delivering those targets sits at the heart of our mission to ensure nature’s recovery. We will look to reduce pressures on species and protected sites, such as pollution and climate change, and we will take action to recover specific species.

I will say a quick word about solar farms, because I know there has been a lot of talk about them, as mentioned by the hon. Member for Wells and Mendip Hills. My understanding from conversations with my biodiversity net gain team is that when we put in a solar farm on grazing land, the actual biodiversity net gain is up to 140%. I understand there are concerns about solar farms, but actually, it is an interesting way to diversify farm income while providing a boost to nature.

Salt marshes have had a bad rap in this debate. They are incredible valuable habitats. Wonderfully mysterious places on the border between land and sea, they are a liminal landscape in constant change, shifting with the tides. They are often overlooked and undervalued and, as we have heard, they can be talked down. I want to speak up for the salt marshes. They play a vital role in supporting species. For many fish, including sea bass and herring, those wetlands serve as essential nurseries—
