A petrochemical business has apologised for unplanned flaring at its Fife plant.
The flaring started off at 22:00 on Monday at the ExxonMobil Chemical Ltd facility at Mossmorran.
Residents claimed “light air pollution turned night into working day” and “considerable noise” meant they were unable to rest.
It follows a few days of prepared flaring by Shell, which shares the internet site and prompted no reviews of issues from residents.
James Glen, chairman of the Mossmorran Action Group, told the BBC Scotland news site that the flaring was however continuing.
He explained: “As soon as once more the night sky in central Fife has been lit up with apocalyptic flaring as ExxonMobil experiences yet another unplanned emergency.
“A significant plume of black smoke testified to the launch of a big amount of unburned hydrocarbons and other harmful pollutants.
“Family members in neighbouring communities were once more compelled to endure comprehensive sounds intrusion, gentle air pollution that turned evening into working day and consequent sleeplessness and nervousness.”
Mr Glen added: “People have been left discouraged when they couldn’t report the unplanned emergency to SEPA as their air pollution helpline proved unable to cope with the volume of calls.
“People today have submitted studies to our team of disturbed slumber, nausea, worry, anxiety, complications, sore throats and burning eyes during this excessive flaring party.
“In 2001 the then shadow health minister, Nicola Sturgeon promised inhabitants a general public probe into Mossmorran, eighteen yrs later inhabitants are continue to waiting.
“Public calls for an independent social effects study has fallen on deaf ears, as the very first minister, and health minister Roseanna Cunningham dismiss the plight of residents.”
Stuart Neill, exterior affairs manager for ExxonMobil stated: “We can validate that we have professional mechanical failure across two of our a few boilers.
“With the reduction of this steam generation, we are not able to keep on to function our typical processes.
“As this sort of, we are progressing with the unit shut down to allow for us to consider the root trigger and execute required repairs.
“Flaring will be necessary even though our team take the actions expected to securely shut down operations.
“We will constantly function to minimise the timelines, and will update you as these are confirmed.
“We, once more, apologise if flaring is resulting in any concern but reiterate that the method is harmless and poses no danger to communities.”
