As the flaring entered its fifth day today, complaints from the public now exceed 600. The figure is among the highest it has ever received for a single incident.
SEPA launched a full regulatory, air quality and noise monitoring programme in response.
The regulator issued a final warning letter to the firm a year ago following flaring that it found to be “preventable and unacceptable”. Permit conditions were tightened in response. SEPA and the Health and Safety Executive also began a joint probe last year.
