A permit has been issued for a company to drill a borehole near Llandow in the Vale of Glamorgan to explore for oil and gas.
Natural Resources Wales says an environmental permit has been issued for Coastal Oil and Gas, based in Bridgend, to drill in Llandow Industrial Estate.
The permit ensures that waste such as rock and soil is recovered or disposed of in a way that protects the environment and local communities says NRW.
NRW says it does not allow the company to conduct any hydraulic fracturing or ‘fracking’ to extract any oil or gas.
The drilling and testing operations and work to reinstate the land should last no longer than 12 months.
