A developer has been told to restore a well known quarry site in Caernarfon as it withdraws its proposal for a concrete crushing plant. Seiont Brickworks closed in 2008 - ending a 200 history of brick making in Caernarfon. It was taken on by Jones Bros to be used as a compound during the building of the £140m Caernarfon bypass, which was completed in 2022. The company then put forward two proposals for the large site. These were for a gas fired short-term operating reserve plant and a concrete batching facility. Both schemes triggered major opposition from local residents concerned about the impact of the developments. The first project was rejected by Welsh Government planners and the second scheme - which would have gone before planners at Cyngor Gwynedd - has now been withdrawn. Meanwhile Cyngor Gwynedd has commenced formal enforcement action - telling the company to remove equipment from the site and submit a restoration plan. The company told North Wales Live they have sent proposals for the restoration of the site to the council and are now for waiting their feedback ahead of a formal application to restore the site. “These two proposals have been the subject of a long and determined campaign led by the local group Caernarfon Lân,” said Siân Gwenllian, Plaid Cymru Senedd member for Arfon. “Following the very welcome decision to refuse the gas plant, I understand that the concrete crusher application has now been withdrawn and that the company has been instructed to restore the site in line with the original planning agreement. This is excellent news and a clear example of how effective, well-organised campaigning can deliver real results for local communities. “People were rightly concerned about pollution, noise, and the wider environmental impact of fossil fuel developments so close to homes, a hospital, a school and the town’s rugby club. We’ll need to keep a close eye on what happens next, but I hope this marks the end of the matter and brings some reassurance to Caernarfon residents.” A Cyngor Gwynedd spokesperson said: “We can confirm that planning application C24/0297/19/LL for the Seiont Quarry site has been withdrawn by the applicant.

When we receive their comments, we will be able to develop full plans and submit the necessary applications for planning approval."
