DJ Taylor (Anglian Oils) has been fined £10,000 after it admitted causing pollution with vehicle wash detergents as well as vegetable oil from its yard.
In an Environment Agency (EA) prosecution, King's Lynn Magistrates' Court was told how in August 2010, officers discovered that surface water drainage from the firm's site in Downham Market, Norfolk, had polluted a nearby lagoon.
Pollution had then flowed into a watercourse, turning it a dirty white colour, contrary to the Environmental Permitting (England and Wales) Regulations 2010.
The court was also told that staff at the company had not been trained to an appropriate level, which led them to disposing of oil-contaminated water to surface water drains on site.
DJ Taylor (Anglian Oils) - authorised for 12 vehicles and 10 trailers - said that since the incident they had stopped washing trucks on site.
They had also installed two water storage tanks to store the oil-contaminated process water. This was now sent off for treatment and the interceptors were checked regularly. The company was also ordered to pay costs of £4,427.
