Two Yokshire waste firms run by the same pair of directors have been fined £10,000 each for burning waste without a permit.
Grantscope and RG Wastecare burnt waste at Boulder Bridge Lane, Barnsley, despite the permit held by Grantscope prohibiting burning of any sort.
The judge said she was satisfied the fires were deliberately lit on a number of occasions and were financially motivated. The Judge also said efforts were made to avoid the detection of the fires.
Director of both companies Dean Ryder, of Doncaster Road, Barnsley, was fined £5000.
RG Wastecare employee John Clifford, of Lewis Road, Lundwood, Barnsley, was fined £200.
Both waste management companies, and both individuals, were ordered to pay costs totalling £15,076 to the Environment Agency, which brought the case at Barnsley magistrates court.
Speaking after the case, EA officer Brad Haystead said: “Boulder Bridge continues to be a high priority area for the EA.
“Our officers spend a lot of time and effort working with operators and partners to improve the environment and minimise impact on the local community, but in cases like this where there is deliberate serious offending we’ll use our enforcement powers to take action.”
