Oil and gas companies are regularly breaching their legal produced water permit allowances, Oceana’s report claims. Yet, in line with official government reporting requirements, these breaches are not registered as accidental oil spills. Indeed, Sea Slick counts a total of 723 permit breaching incidents in the last three-and-a-half years – that’s equivalent to 17 oil or chemical spills each month.

Currently these permit breaches aren’t counted as accidents. They’re not really counted as anything – other than permit breaches. If these unaccounted-for permit breaches are factored into official government data for accidental oil spills, Oceana estimates that the volume of oil spilling into UK seas increases by at least 43%.

The oil and gas sector are keen to reassure the public that chronic oil pollution can be quickly dispersed and poses a low risk to marine life or human health. Certainly, if incidents were rare, this might be a more persuasive argument. But they aren’t.

Getting serious about sanctions

Oceana’s research highlights that oil and gas companies have only been fined on two occasions in the last five years. One was for just £7,000.
