Waste which has been dumped on a site in Oswaldtwistle will begin to be removed early next week.
Around 3,500 tonnes of waste left on the site of former NIPA Laboratories at Nook Lane is to be removed following discussions between the Environmental Agency, Hyndburn Council, Lancashire County Council, landowners Lockgate/Amcis and Blakeley's Waste Management Limited.
The bales which have been left at the site are being blamed for the fly infestation affecting thousands of residents.
Around 300 people attended a meeting on Thursday, July 26 where Oswaldtwistle Councillor Peter Britcliffe told residents the waste was being removed.
He said: "We met with the site owners this afternoon and they have agreed to start removing the rubbish from the site on Sunday or Monday. I believe they are removing it because of the action because of the protest from residents at Nook Lane last night."
Residents gathered on Nook Lane on Wednesday, July 25 to voice their concerns to the Environmental Agency.
Speaking during Thursday night's meeting, Councillor Clare Pritchard, deputy leader of Hyndburn council, said the council will continue to monitor the fly infestation in the weeks ahead.
She said: "Contractors are on site spraying twice daily and this will continue.
"We estimate it will take approximately 400 wagon loads to remove the waste. We will work to get this done as soon as possible."
Contractors were due to visit the site on Friday, July 27 to prioritise removing the waste bales that are causing the most problems, and to find ways to eradicate the fly infestation.
Steve Molyneux, environment manager for the Environment Agency in Lancashire said, officers will be onsite to monitor the removal.
He said: "We understand that this issue has been distressing for the local residents and business. However, we wish to ask the local residents to remain patient while the waste is removed. In working with the council we hope to have the issues in the area resolved soon."
