One business owner said the courtyard at the site had laid empty since a major fire last September.
The EA said it first issued the operator with a suspension notice on 17 February, due to piles of wood and plasterboard exceeding safe limits and a failure to maintain fire breaks.
But after reports of recent vehicle activity, inspections on 23 and 25 February confirmed new waste had been brought onto the site and added into a pile of waste about 6m high, both inside and outside of the main shed.
In a statement, a spokesperson for the EA said it was committed to stopping “waste criminals”.
“Working with local councils, the police force and our other partners in Worcestershire, we’re committed to stopping them,” they said.
Together we’re pulling every lever available to us to disrupt those who profit from the harm illegal waste sites cause.”
