Cuadrilla warned for releasing tonnes of methane

Fracking firm Cuadrilla Resources has breached three of its environmental permitting conditions, according to an Environment Agency (EA) audit of its Preston New Road shale gas exploration site.

The regulator conducted a day-long inspection of the site’s gas flaring operations at the end of February, with subsequent technical evaluation and data assessment concluding on 20 March. A report detailing its conclusions was released this week.

It covers a period when nitrogen was being injected into the well, with intermittent flaring. This reduced the concentration of methane in the gas entering the flares to less than 40%, the minimum level needed for them to light.
