One of the UK's biggest building suppliers has been fined £40,000 for illegally storing and treating waste.
Jewson last week pleaded guilty to stockpiling soil, subsoil concrete, metal and asbestos cement at the rear of its Leamington Spa branch.
Officers from the Environment Agency investigated the area, surrounded by housing on three sides, in February 2004 following complaints by members of the public.
"This was of great concern to local residents, with both brown and white fragments of asbestos cement found to be onsite, posing a potential risk to human health."
In mitigation, Rugby Magistrates Court heard that Jewson had no previous convictions, had entered a guilty plea, had co-operated fully with EA during the investigation and had made no profit from the activities.
The court was told that following the investigation Jewson spent 108,000 to dispose of all waste materials on the site.
As well as the fine, Jewson was ordered to pay the EA £6,181 in costs.
