The independent oil and gas regulator, the Oil and Gas Authority (OGA), is responsible for ensuring operators mitigate the risk of induced seismicity. The OGA is continually monitoring operations around the Preston New Road site to ensure they remain in line with Cuadrilla’s Hydraulic Fracture Plan, which was independently approved by the OGA, Environment Agency and the Health and Safety Executive (HSE) before the commencement of hydraulic fracturing operations.

The Traffic Light System dictates that if an event of 0.5ML or above is detected and causally linked to operations, Cuadrilla must pause operations for 18 hours and reduce well pressure. Operations are only allowed to resume once regulators are satisfied that any risks have been appropriately mitigated. The very minor seismic events recorded at the Preston New Road site cannot be felt at the surface.
