The Environment Agency (EA) is appealing for witnesses to the illegal dumping of around 3000m³ of waste at a Bedfordshire warehouse.
Specialist EA waste crime officers discovered the dumping after they were called to the site in Dunstable.
Investigations revealed the dumping occurred during nights between 16 and 20 November last year.
The waste is due to be removed soon, but at the expense of the landowner.
Tracy Nash, environmental crime team leader, said: “This is not a matter of small scale fly-tipping, this case appears to be intentional large scale avoidance of disposal costs.
“This callous act has endangered the environment and had a costly impact for the land owner. It is vital that we identify where the waste came from and who transferred it to the warehouse.
“If an innocent party has handed it to a contractor for disposal in good faith then they won’t be in any trouble and may have critical information for us.
“The waste must have been taken to the site in several large vehicles, and with the hole having been cut in the side of the warehouse, we’re hopeful that someone may have seen something suspicious, such as tipper lorries or plant machinery on the site in mid November.”
Anyone who has any information can contact the EA on 0800 807060 quoting CMS 16469 or if they wish to speak in confidence, to Crimestoppers on 0800 555 111.
The EA stated: “Illegal dumping costs taxpayers hundreds of thousands of pounds a year in clean up costs.”
- The call comes after a Eunomia report estimated that waste crime may be costing the UK economy as much as £808m, with fly-tipping one of the main issues.
