Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government what checks will be undertaken to ensure that no contaminated waste material arising from the construction of the new Hinkley Point power station will be shipped for depositing in the Cardiff Grounds; and who will conduct those checks.

The sediment has been sampled and tested for chemical and radiological substances. An accredited laboratory, Centre for Environment, Fisheries and Aquaculture Science (Cefas), has undertaken the testing and analysis in accordance with international guidelines. Permission is only granted to dispose of material that is deemed safe according to these internationally established guidelines.
