Between May 13–14, 2004 the site was enclosed with temporary mesh fencing and plain-clothed security guards commenced patrols of the public areas. At 02:00 on May 15 bulldozers arrived at the site and tree-felling began at 07:00. The work caused immediate concern to nearby residents who feared the work might unsettle asbestos deposits in the ground. Residents formed the Save Spodden Valley action group the following week. Residents also protested to Rochdale Council, which subsequently issued an emergency tree preservation order on six parts of the site, preventing the removal of trees without permission of planning officers, and carrying a fine of up to £20,000 per tree. The Health and Safety Executive (HSE) also secured a voluntary arrangement to halt any work that could disturb soil on the site pending soil sampling. Former Turner's employees and local residents claimed that, as recently as the 1960s, asbestos dust and fibres were clearly visible hanging from the trees, and that a disused coalmine shaft exposed by the tree felling had been used over a period of decades to dump hundreds of tonnes of asbestos waste.
