R M Penny (Plant Hire and Demolition) has also been given a one year conditional discharge by local magistrates.
The case was brought by the Environment Agency because the company had not checked whether the place it was dumping the waste, Rugbourne Farm at High Littleton, was still a licensed tip. There had been a landfill site in the farm but this closed in 1992.
The Agency said in a statement: "RM Penny provided the Agency with waste transfer notes showing where the waste had come from. This meant checks could be made on the type of waste and whether it was likely to have included contaminated material.
"However, it failed to check whether Rugbourne Farm still had a valid tipping licence. RM Penny has been in the haulage, waste management and demolition business long enough to know how important it is to check whether relevant permissions are in place before they tip."
