There are calls for the Scottish Government to start planning for the closure of the Mossmorran plant.
It comes after what some have called the worst flaring ever there over the Easter weekend and environment agency SEPA receiving their highest number of complaints ever.
The call comes from Mid Scotland and Fife MSP Mark Ruskell who says a report into the health impacts of flaring needs to be carried out.
He has told Kingdom FM News: “There’s no sign from Mossmorran’s owners that they are prepared to invest to give the plant a future, so its becoming increasingly clear that it will need to shut down.
"A study into health impacts is important and despite commitments given to me from the Public Health Minister we see no progress, however continuing to stare at the problems Mossmorran creates doesn't deal with the solution.
"We need to learn the lessons from Longannet and ensure that a long term plan to shut the site is started now, ensuring that no workers at the plant are left behind.
"The Just Transition Commission has been set up specifically to deal with these difficult long term questions about how changes can take place and should be brought in to discuss a future plan with unions, communities and the plant operators.
Stuart Neill, external affairs manager at ExxonMobil Fife Ethylene Plant, said: “We note Mr Ruskell’s statement, and would welcome the opportunity for an informed discussion on the points he has raised.
"Only last week, we shared directly with Mr Ruskell our planned multi-million pound investment programme that will work to further minimise the frequency and impact of unplanned flaring.
"This is in addition to investments in maintenance and modernisation totalling over £100m in the last five years alone.
"We, again, invite Mr Ruskell to visit the Fife Ethylene Plant to better understand not only our operations, but also the vital economic and employment benefits we bring to communities in Fife.”
