Environmental Control Measures at Greengairs Landfill Site

The paper describes a programme of infilling, the first phase of which will bring an immediate improvement to the amenity of Greengairs village and will screen the subsequent filling operations from view. The landfill is technically advanced, being designed as an engineered leachate attenuation site but including full back-up control facilities. These take the form of a full underdrainage blanket under the first two phases, which will collect attenuated leachate and allow confident predictions of the site's behaviour for the design of subsequent phases. A landfill gas-collection and control system was incorporated in accordance with laid-down guidelines. Other factors which have significant environmental effects are the control of site surface waters and their interaction with groundwater, mine drainage, and the receiving waters.
