Rhydymwyn Buffer Depot and Tunnels Access in 2026 - Part 3
In 2008 about a dozen of us formed RVHS to research the Valley Site and report on our findings. In the intervening years we have been on a marvellous journey but then was then and now is now.
There have been major changes recently which totally change what is available and what our access is to it.
As we are now better informed, we can report on what is being offered by Defra and how we can best integrate with that. This is not a short-term casual issue, major changes have been made, and we wish to be able to contribute in the fullest way to the long-term future of the site and its importance. There are so many people who wish to be involved.
To achieve this, we need to tell all of you, in a broad way what is the situation today, we will then call a full meeting and answer any questions, and you will be able to choose how you wish to progress.
We believe that we are acting in a mature and responsible way.
Best Regards
Colin
