Nicholas Willsmore pleaded not guilty to four charges relating to the deposit, keeping and burning of waste at an unlicensed site, contrary to sections 33(1)(a) and 33(1)(b) of the Environmental Protection Act 1990. However, the court decided his testimony was "not credible".
The case amounted to "a deliberate or reckless breach of the law that continued despite repeated warnings," it said.
The Environment Agency first investigated the site in January 2001 following complaints from local residents. Mr Willsmore repeatedly agreed to remove the waste but failed to do so until August 2004, at a cost of £8,500.
Kevin Smith and Andrew Wilson each admitted five charges relating to the deposit, keeping and treating of waste contrary to section 33 of the 1990 Act.
Agency officers first discovered the offences when they visited the site in October 2002. The two men failed to comply with enforcement notices served by the Agency that December requiring them to remove tyres from the site and to stop shredding tyres until a licence was issued.
The tyres were finally removed after notices were served again in November 2004.
