New UK shale delays over radioactive waste water release.

BBC.co.uk: “Energy company Cuadrilla has withdrawn applications for permits to frack in Lancashire after issues with radioactive waste. Fracking produces large volumes of water contaminated with low level naturally-occurring radiation.”
“The Environment Agency (EA) said it would not grant a radioactive substances permit until it was sure the water will be disposed of safely.
Cuadrilla said it was preparing new permits to meet revised guidelines.
….When Cuadrilla Resources fracked at Preese Hall, Weeton the agency found traces of naturally-occurring uranium and thorium. It also found levels of radium 90 times higher than naturally occurs in drinking water.
….Previous regulations classed the waste water as industrial effluent and Cuadrilla was legally authorised to discharge two million gallons into the Manchester Ship Canal after being processed at the Davyhulme treatment works in Trafford.
Flowback water is now classed as radioactive waste following European regulations which came in to force in October 2011.
Without a valid permit, the company can drill, but not frack and the operator and treatment works need a permit to safely dispose of it.
Cuadrilla said: “Following recent changes in the Environment Agency’s guidance on permits and an ongoing review of our exploration programme, we have decided to withdraw the previous permit applications for our sites in Lancashire.
“We are preparing new permits and will provide further detail when we announce a number of proposed new exploration sites.
“We will need a radioactive substances permit to flow test any well after fracturing.”
