These works are explained in a reply I got when I made enquiries about the spraying -
At Whinney Hill currently, they have installed and are using a temporary deodoriser (located to the left of the site entrance and up Whinney Hill Road) due to engineering works being carried out on the old part of the site to improve environmental performance. This work involves installing an engineering cap to the landfill which will reduce infiltration of rainwater (and so protect groundwater, as well as allow more efficient collection of landfill gas and use in the gas engines (to produce electricity) and not lost to the atmosphere (greenhouse gas). Part of this work does involve partial re-profiling of the flanks of the landfill therefore old waste has been dug into and moved to other parts of the site. http://www.accringtonweb.com/forum/f...tml#post477781
