Samuel McIlroy of Crumlin became only the second person to be jailed for waste offences in the province after appearing for sentencing at Craigavon crown court on 4 December.
The Environment and Heritage Service first investigated Mr McIlroy’s site off the Sevenmilestraight, Antrim, in May 2004.
Officers found at least 5,000 tonnes of biodegradable household waste originating from the Republic of Ireland buried there. Leachate was escaping from the site and polluting a tributary of the Dunore river.
Mr McIlroy pleaded guilty to three offences under the Waste and Contaminated Land (Northern Ireland) Order 1997 and one under the Water (Northern Ireland) Order 1999 before Antrim crown court in October. He was sentenced to six months for each offence, to run concurrently.
The first custodial sentence for a waste offence in the province was given last year to a farmer who buried more than 4,500 tonnes of household waste from the Republic on his land (ENDS Report 378, p 55 ).
