Two Portadown companies have been fined a total of £13,412 after being found guilty of breaches of waste management legislation.
The fines were imposed on Monday at Craigavon Crown Court.
Portadown Recycling and Skip Hire of Brownstown Business Centre was fined £7,000 for dumping controlled waste on land without a licence.
A compensation order for a further £5,912.10 was granted to HM Revenue & Customs for lost revenue.
Jameson Properties, the site owner of the same address, was fined £500 for keeping controlled waste, or knowingly caused or knowingly permitted controlled waste to be kept in or on any land without a licence.
The offences related to a site inspection carried out on May 10, 2011 by officers from the Northern Ireland Environment Agency (NIEA) at lands off Derrycor Road in Portadown.
They found a range of illegal waste deposits including brick, concrete, tiles, wood, metal, rubber crumb, glass and plastic bottles, buried on site.
Much of the waste had been through a mechanical process and had been shredded before being dumped.
An NIEA survey showed that approximately 7,639 tonnes of waste had been deposited on site without the necessary waste authorisations.
Portadown Recycling and Skip Hire had pleaded guilty, at an earlier hearing, to depositing 1,970 tonnes of waste (without there being a licence or exemption in place) at the Derrycor Road site.
An NIEA spokesperson said, “This is a significant outcome which has prevented further waste crime and environmental damage from taking place.
“NIEA officers will be continuing their efforts to ensure that environmental legislation is vigorously enforced in serious cases such as this.”
