Geological Concerns Regarding Fracking Regulation

The UK system of regulation of fracking imposes a range of strict geological controls on operators – including seismic surveys, safe distances, seismic monitoring, a traffic light system, and barriers to fugitive migration. Experience and professional advice suggest however that each of these controls is
flawed e.g.

1. Seismic surveys are invariably incomplete and incapable of detecting small fault lines and minor vertical displacement which could lead to earthquakes.

2. The EA formula for calculating a safe distance between fracking propagation and fault lines is unduly optimistic and should be replaced by a minimum distance of at least 850 metres horizontally.

3. The sequence of events at both the Preese Hall and PNR sites implies inherent instability in the stress planes of the fault lines in the Bowland Field.
