Hinkley Point – Saltmarsh Proposals
On the 9th September 2024, our parish learned that EDF – the builders of the Hinkley Point C nuclear power station – were looking at areas of the Kingston Seymour parish (and the adjacent Clevedon) to create areas of saltmarsh.
This page will be a repository for documents which relate to this activity and for the information of parishioners and others.
The latest items are at the top.
There is also a link to a repository of documents produced by (and curated by) EDF that are too large to load directly onto this website. This is under the entry for the 23rd October 2024. Please scroll down for more.

Please see the following statement from Mike Sewell, Chair of the Parish Council
Earlier this week the Parish Council was contacted by the Sunday Times in relation to an article they are preparing on how the development of major infrastructure projects, such as Hinkley point, are affecting communities, particularly with the governments drive to net zero emissions.
This led to a very hastily arranged visit by their Science Editor, Ben Spencer, who visited the village for an hour on Tuesday having already visited Hinkley Point and WWT Steart Marshes to meet me to better understand the effect that EDF’s Saltmarsh plans have had and could have on our community.
During these discussions Ben shared that he had recently had a meeting with Natural England where they were expressing some concerns with regards to the results coming out of the EDF Acoustic Fish Deterrent (AFD) tests which have currently placed all previous EDF plans re Saltmarsh creation in our community on a hard pause as we confirmed in March this year.
We have no official feedback on these tests and do not expect further feedback from EDF before an arranged meeting in September, we have however asked EDF for an update, but nothing received yet.
EDF have previously made it clear that their worst-case position even if their AFD trials are not successful is that they do not consider saltmarsh, to the scale proposed, proportionate and that even if they had to revisit this issue their approach would be quite different. Any future works would have to be by local agreement only.
We expect the Sunday Times article to be published this weekend (Sunday 18 May 25), we have not seen it and will of course follow up on any issues raised outside those we expect to see.
We will continue to liaise with EDF and all relevant parties to monitor the progress of the AFD trials to ensure that the saltmarsh issues we have experienced do not resurrect or repeat.

A MOMENTOUS DAY! A statement from the Chairman of Kingston Seymour Parish Council
Yesterday I attended a call with EDF and today I have received confirmation of the following:
- EDF is halting the development of any saltmarsh mitigation for Hinkley Point.
- They have sourced what looks to be an effective Acoustic Fish Deterrent (AFD) solution that is maintainable and are now entering into comprehensive tests for the rest of 2025.
- They are writing to landowners and the press from today confirming that they are introducing a pause on all activity and revoking their section 172 compulsory access rights from 31 Mar 25. In addition, all wildlife survey data collected will be provided to our community.
- EDF have made it clear that their worst-case position even if their AFD trials are not successful is that they don’t consider salt marsh, to the scale proposed, proportionate and that even if they had to revisit this issue in 12 months’ time their approach would be very different. Any future works would have to be by local agreement only.
I have provided below a copy of the correspondence that EDF have issued today. Here (PDF opens in a new window) Although covering their position with a ‘Hard Pause’, EDF are clear they prefer the alternate AFD proposal, it is a proven technology and they expect trials to be successful given the proven nature of the solution.
This is good news for our village and the wider community. The last few months since September 2024 have been very trying ones for us all, hopefully this decision by EDF will allow our community to move on and put this episode behind us.
We will of course continue to liaise with EDF and monitor the progress of their AFD trials to ensure that this issue does not resurrect or repeat itself.

At a meeting of the Kingston Seymour Parish Council on Monday 21st October, Councillors formally voted unanimously that the parish council would resist the attempts of EDF to create saltmarsh in our parish.
Similar discussions have been taking place in the three other parishes threatened with such actions and today, a Joint Statement from the chairs of Arlingham, Westbury-on-Severn and ourselves has been issued and is here Joint Statement from Parish Council chairs (PDF opens in a new window)
Aust Parish – the fourth threatened area – are meeting on the 15th November and are expected to ratify the statement.
