The screening report hosted on this site is a technical exercise across England, Wales and Northern Ireland. No specific location in England, Wales or Northern Ireland has been identified as a potential GDF site. Any future decision on geological disposal would be subject to community agreement and planning and environmental consents.

Details

Our work shows that we may find a suitable geological setting for a GDF in most of this subregion.

Given that most of this subregion is the area which extends to 20km from the coast, rock can only be seen at the surface at a few locations in the Vale of Clywd including man-made excavations such as quarries or road cuttings. A small number of and give us an understanding of the geology at depth.

There are various types of and we .

There are layers under most of the subregion in which we may be able to site a GDF. There may also be layers of under the northern half of the subregion in which we may be able to site a facility. We would need to do more work to find out whether these rocks have suitable properties and thicknesses.

Even where individual clay-rich rock layers are found not to be thick enough to host a GDF they may support the siting of a GDF in deeper rocks as they could act as a barrier to from depth. This is important because is one of the ways in which radioactive material could be carried back to the surface.

There are no known coal, oil, gas or metal in this subregion which means that it is unlikely that future generations may .

Parts of this area, off the coast around Rhyl, are allowing companies to explore for coal. It is not known whether coal in these licence areas will be exploited. RWM will continue to monitor how this exploration programme progresses.
