of the rock formation causes the ,fluid, to return to the surface. Known as “,flowback,” or “produced water,” this ,fluid, can contain the injected chemicals as well as naturally occurring materials (hydrocarbons, brines, metals, and radionuclides). The ,flowback, is stored on site in tanks or pits before treatment, disposal, or re-cycling.

On the issue of flowback fluid, the guidance states that: Flowback fluid can be treated and reused as fresh injection fluid for the purpose of hydraulic fracturing and we consider this to be a suitable environmental option. Flowback fluid must be reused where it is reasonably practicable to do so to meet the Mining Waste Directive (MWD) obligation to minimise waste.
