Breedon Trading Limited (trading as Welsh Slate) has submitted two planning applications for Penrhyn Quarry. The first planning application seeks a small lateral extension to the working area of the quarry at its south-western corner. Land associated with the proposed extension lies wholly within the boundary of the current planning permission. The second planning application seeks to amend the current planning permission in so far as it relates to the life of the quarry.

These proposals have been amended from those previously consulted on between 11 December 2020 and 22 January 2021 as part of the formal Pre-Application Consultation process. In this respect, the extent of the proposed extension has been reduced to 1.6 hectares (ha) so that it lies on the inside of the drainage leat that bounds the quarry. In view of the reduced extension, and in the light of being able to sell more of the quarry waste, the requirements for additional tip capacity has reduced. Accordingly, it is no longer proposed to amend the tipping arrangements from those current approved. In fact no other changes to the way the quarry has operated over many years are proposed.

The key facts are: -

The application site is 2.3 hectares in area, but only 1.6 hectares would be quarried;

If it’s approved it will increase the amount of slate permitted to be quarried by 250 000 tonnes, or 3.6 million tonnes overall;

It’ll increase the life of Penrhyn Quarry from the end of 2023 to the end of 2035, and;

In all other respects the quarry will continue to operate as it has for many years, including the disposal of mineral waste.

The application includes: -
