Wolverhampton Crown Court heard that the company had been advised how to prevent oil pollution after a small patch of oil was spotted on the canal in January 2000. A subsequent visit by Agency inspectors found that the problem was continuing. The Agency sent a warning letter, but in April about 80 metres of the canal was covered in oil. An investigation traced the source to diesel from a surface water drain on AP's site.
The company was fined and ordered to pay prosecution costs of £1,624.
