The Environment Agency has served another Enforcement Notice on the Waste Recycling Group (WRG), which operates the sprawling Welbeck tip at Normanton.
The action, taken under the agency's regulatory powers, comes after a report in December which revealed 13 breaches of site operating conditions.
They were identified during a detailed check of the Welbeck site by agency officers during the summer. By December most had been rectified, but WRG was given a strict deadline to sort out the others.
Today the agency confirmed it had served another Enforcement Notice on WRG after an inspection last Monday.
A large quantity of waste derived from the fragmenting of scrap vehicles was discovered exposed at the landfill site, breaching one of WRG's Waste Management Licence conditions.
Agency environment management team leader Roger Wilde said: "This issue was raised following a major audit of the site in July 2002. As a result of this, there was a marked improvement but the situation has begun to deteriorate. The agency has now issued WRG with an Enforcement Notice under the terms of its prosecutions and enforcement policy.
"Agency officers will continue to visit the Welbeck site on a regular basis and also make unscheduled visits to ensure that licence conditions are being adhered to."
The Enforcement Notice, served on January 28, calls on WRG to cover over the fragmented waste. It has 14 days to comply.
The agency warned that any further breaches of this condition could lead to a more severe penalty being imposed.
No one from the Waste Recycling Group was available for comment.
The tipping site, owned by Wakefield Council, takes in thousands of tonnes of rubbish, some of it toxic.
Meeting
It has been opposed for more than ten years by the Altofts-based action group RATS (Residents Against Toxic Scheme).
RATS president Paul Dainton welcomed the latest action, but said they had reported the problem to the Environment Agency with nothing being done about it.
He said: "The enforcement notice is for not covering toxic waste on the surface of the tip. In other words, toxic waste at Welbeck has been blowing all over the site with no control whatsoever. RATS have reported three times this year that the tip is not covered and the agency has refused to accept our complaint."
• RATS is holding a public meeting at Lee Brigg WMC in Altofts tomorrow at 7.30pm to discuss several issues, including breaches of site licence conditions at Welbeck.
