THE Scottish Environment Protection Agency has today, Thursday, announced a formal regulatory investigation into the ongoing flaring from ExxonMobil Chemical Limited at the Mossmorran petrochemical plant.

And they pointed out that an 'unprecented' number of complaints had been received by their Hotline from residents.

The investigation was announced by SEPA Chief Executive, Terry A’Hearn, as flaring enters its fifth day at the Mossmorran Fife Ethylene Plant. The move by SEPA follows ‘Final Warning Letters’ issued to ExxonMobil Chemical Ltd in April 2018, regarding flaring which was found to be “preventable and unacceptable”.

It also follows SEPA and Health and Safety Executive investigations in 2018/201919, a tightening of permit conditions and an instruction to conduct a ‘Best Available Technologies’ (BAT) assessment, due shortly.

On Easter Sunday, SEPA responded to complaints of unplanned flaring at ExxonMobil Chemical Ltd, Mossmorran. Whilst flaring is an important safety mechanism and is permitted through permit conditions, SEPA deployed a full regulatory, air quality and noise monitoring response which will inform SEPA’s understanding of the nature of the event.

With the operational response continuing across the duration of the incident, including regulatory and noise monitoring, air quality monitoring carried out on Monday April 22 showed no cause for concern.

With ExxonMobil Chemical Limited advising that flaring is likely to continue over the coming days, SEPA has reinforced to the site operators the importance of restarting the plant as quickly as possible with the minimal amount of elevated flaring.

Over 600 complaints have been received to date by SEPA’s 24 hour Pollution Hotline, one of the highest number for any single event.

Terry A’Hearn, SEPA’s CEO, said: “Every day, SEPA works to protect and enhance Scotland’s environment and compliance with Scotland’s environmental rules is simply non-negotiable. In addition to working hard to ensure ExxonMobil brings a halt to the flaring as quickly as possible, we have also launched this investigation into the incident.

“The unprecedented number of complaints we have received is a clear message and it’s one that we have heard powerfully and clearly. I want to thank everyone who has taken the time to help us understand the impacts of this flaring, and I encourage people to continue to report to us.

“The Mossmorran complex is a major industrial facility, where this type of flaring is a legitimate safety mechanism, but it’s been happening too often, and the current level and extent of the flaring from ExxonMobil Chemical Limited is unacceptable.”

SEPA will provide as much information, as quickly as possible, within the constraints of a live regulatory investigation. Updates will be provided across our online hub, where communities can sign up for email updates.
