Production at the Mossmorran ethylene plant in Fife resumed on 21 February 2020, after a five month shutdown.
On 3 March 2020, the Scottish Environment Protection Agency (SEPA) was notified by ExxonMobil Chemical Ltd of unplanned and elevated flaring at the complex, with normal operations reported to have resumed the following day. SEPA reported that their officers deployed air and noise monitoring during this period of unplanned flaring, with initial data suggesting no breach of UK air quality standards.
Whilst recognising that flaring is an important safety mechanism, SEPA highlight that this incident is a reminder that the plant operator should take short- and medium-term steps to mitigate the flaring, including noise-reducing flare tips and bringing forward plans for fully enclosed ground flares.
