Terrence Maldwyn Wiberg of M&R Commercials, Ferry Boat Close, Swansea, was ordered to pay full legal costs of £1,595 to Environment Agency (EA) Wales.
The court heard that Wiberg was issued with a licence to dismantle scrapped vehicles in October 2004, by EA Wales, which required him to put in place safeguards to ensure his activities did not cause pollution.
After he failed to implement these safeguards the Agency served notice on Wiberg in January 2005, and took him to court when he failed to comply with the notice.
Swansea magistrates issued Wiberg with fines of £2,000 for each offence, with the view that he had ignored the EA for several years.
EA Swansea environment management team spokesperson Jeremy Walters said: “We gave this operator every opportunity to avoid this court action. I hope this case will send a clear message to those operators who think that they can flout the law and carry on without any regard for their local environment.”
