On 11 December, the Environment Agency (EA) said preparatory work to remove the tip would begin “imminently”, but Miller told MPs nothing appeared to have been done.
Responding to Miller in Tuesday’s adjournment debate, Creagh said: “The Environment Agency will continue to closely monitor the site whilst preparatory work takes place.
“This is an absolute top priority for this government, my message to the waste criminals is: ‘We are coming for you and we are going to shut you down’.”
Miller said protecting the people removing the waste and protecting the environment “just takes that bit longer”.
“But I will continue to put pressure on the government and the Environment Agency to get it done as quickly as possible.”
An EA spokesman said the criminal investigation “continues at speed”.
