Pembroke power station 'breaches environment laws'
A new £1bn power station in Pembrokeshire could be forced to change its cooling system because of concerns that its current technology is breaching conservation laws.
A leaked document seen by BBC Wales reveals that such is the concern of the European Commission that it has sent a formal notice of infringement to the UK Government and lists 18 violations of four separate environment laws.
But RWE npower, which built the power station, said the plant's development had been thoroughly scrutinised.
