Mossmorran has returned to normal operations after severe weather led to flaring at the site. 

Plant bosses blamed "extreme weather" for what they described as a "process upset" yesterday.

Shell Fife NGL Plant manager Craig Burnett thanked the community for their patience during the episode. 

However, work will start on the plants annual 'Turnaround' and you should expect to see flaring between August 18 - 22, starting Tuesday.

Fife Ethylene Plant, operated by ExxonMobil, has now also safely returned to normal production. 

In a statement released this afternoon, Craig Burnett said: "Following my community notice issued yesterday (12 August) regarding the use of our elevated flare due to the extreme weather, we have now safely returned the plant to normal operations.

"Thank you for your patience during this time and I apologise for any inconvenience caused.

"I would also like to notify you that next week we will start our annual ‘Turnaround’ at the Shell Fife NGL plant. The Turnaround is an important activity for the maintenance of the plant so that we can continue to operate effectively to our safety standards and industry regulations.

"In order for this work to be carried out safely, we need to empty Module 1 of hydrocarbons, which will require the use of the flare.

"As usual, we will prioritise the use of the ground flares to minimise the impact on the community but you may see occasional, short periods of low intensity flaring in the elevated stack between Tuesday 18 and Saturday 22 August. We do not expect each period to be for more than a few hours.

"We have informed the regulator SEPA of our intention.

"Please contact us if you have any questions or comment. Our notices and contact details are also on the plant website."

Later in the evening ExxonMobil said: "While the flare is part of our many safety systems, we understand the need to minimise community disturbance and our team made every effort to reduce the flare size.

"We appreciate the patience of Communities during this time. Should you have any questions, please let us know."
