Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment he has made of the mode of storage and containment of water that has been used for the hydraulic fracking permitted by the Government to date; and whether any sites have been designated for this purpose.

Flowback fluids from hydraulic fracturing operations are deemed to be a mining waste and therefore require an environmental permit from the Environment Agency for temporary storage on site. Subsequent treatment and disposal of the fluid at a waste treatment facility is also regulated by the Environment Agency. Waste waters must be stored in sealed tanks on bunded storage areas. The storage of wastewaters in open lagoons, as has sometimes been practised in the US, would not be permitted in this country.
