In order to secure beyond 2026 capacity for the treatment and disposal of hazardous wastes and LLW to serve local, regional and national needs, Augean is proposing to construct an additional landfill void of approximately 2 million cubic metres to the west of the currently operated site.
80 per cent of the wastes accepted at the waste treatment and recovery facility and over 95 per cent of the waste accepted at the site for landfill over the last five years comes from the East Midlands, West Midlands, East of England, Greater London and South East regions. No new hazardous waste landfill facilities have been developed in these areas since the current waste management activities at ENRMF were authorised in 2013.
While the implementation of the hierarchy of waste means that generally less waste will be landfilled directly, the treatment of waste results in increasing amounts of residues many of which are hazardous and can only be landfilled. National strategies for the management of hazardous wastes recognise that where there is no better recovery or treatment option, landfill is the end point and the best available technique. The Government LLW policy likewise recognises that after the application of the waste hierarchy principles, final landfill disposal is the safe end point for LLW.
The other elements of the proposed development are:
- The winning and working of minerals in the western extension area in order to create the new landfill void and provide extracted materials for use on site as well as the exportation of clay and overburden for use in engineering, restoration and general fill at other sites.
- The temporary stockpiling of clay, overburden and soils for use in the construction of the engineered containment system at the site and restoration of the site.
- The direct input of waste into the landfill continuing at a rate of up to 150,000 tonnes per annum (tpa).
- An increase to the waste throughput of the waste treatment and recovery facility to 250,000tpa which is an increase of 50,000tpa compared with the currently consented rate.
- A total waste importation rate limit to the site for both the landfill and the waste treatment and recovery facility of 300,000tpa which is an increase of 50,000tpa compared with the currently consented total input rate.
- The continued disposal of LLW limited to that which typically has a level of radioactivity of up to 200 Bq/g.
- The diversion of some of the services that cross the western extension to alternative routes within the application area.
- No change in the operational hours of the site from those already permitted.
- A proposal for a coherent landform for the restoration of the existing landfill and the proposed extension comprising gently domed profiles.
- A nature conservation based after use of the site that includes wildflower grassland interspersed with areas of scrub and trees to integrate with the surrounding woodlands.
- Completion of the landfilling and restoration operations by December 2046. This is a provisional completion date that will be updated as part of the ongoing detailed design works and confirmed in the DCO application.
