Tarmac took over Walleys Quarry

In 1997 Tarmac took over Walleys Quarry and got planning decision for the site to be a landfill (granted by the secretary of state). Planning conditions 2 and 8 of that permission specify that only inert waste, non-hazardous industrial and commercial wastes as well as stable non-reactive hazardous wastes shall be imported into the site.
