The Arley Consulting Company Limited was instructed by P Casey Enviro Limited to compile an IPPC permit application for Arden Quarry Landfill Site, Birch Vale, Derbyshire.  Arden Quarry is an existing non-hazardous landfill which was allocated as a tranche 3 site.

Arden Quarry Landfill Site has been operated since 1998 for the disposal of waste. The installation comprises five discrete landfill cells within an existing sandstone quarry, two of the cells have already been constructed, lined and are currently operated under the waste management licence; the remaining three cells will be developed under the PPC regime.

Leachate treatment is carried out on site in a custom built biological treatment plant. Gas is flared via a 1000 m³/hr ground flare, with gas engines to be installed in the near future.

The site lies on the edge of the High Peak District Park, which is classed as a special area of conservation (SAC) and a specially protected area (SPA).  This site has been defined as a habitat site of high priority under the Habitats Directive

Within the application the following reports were submitted, all according to agency guidelines and templates:

site investigation particulars, engineering design of the site, discussion of monitoring data and the environmental impact of the landfill, detailed drawings.

a review of surface and groundwater status and monitoring results, production of a LandSim model to predict future possible impacts of the landfill on the hydrogeology of the area.

addressing the stability of the basal sub-grade, side slope sub-grade, basal lining system, side slope lining system, waste mass and capping system.

details of the waste inputs and filling regime, containment engineering details, production of a GasSim model to predict future gas production from the site.

identification of site specific pathways and receptors, nuisance effects and control measures to restrict detriment of the amenity of the surrounding area.

identification of site specific pathways and receptors of the designated European habitat, possible detrimental effects and control measures in place to prevent realisation of these effects.
