An application to vary the conditions of the environmental permit (Ref. DP3734DC) was made in July 2020 by the site operator, Walleys Quarry Ltd (formerly named Red Industries RM Ltd), to allow changes to approved landfill operations.
Variations to environmental permits are not unusual during the operational lifespan of a landfill and the specific variations within this permit are standard for such a regulated site. In most cases they are introduced to allow for the implementation of improved operational technologies and techniques, or to add additional conditions to improve regulation.
Applications of this kind do not require public consultation. However, given the level of interest from the neighbouring community, the Environment Agency has decided to carry out a consultation before it reaches its final decision.
The permit variation application proposes two changes. The first relates to the type of material used to cap the landfill as part of the restoration process. The current permit requires the use of a clay layer to seal the site, but the operator has instead requested that a geo-synthetic layer be used. Whilst clay is a widely used and acceptable means of capping, geo-synthetic caps are more effective in controlling landfill gas emissions and offer a better alternative to clay.
The second change involves the introduction of revised limits of methane and carbon dioxide measured at specific boreholes at the perimeter of the site. This will allow the Environment Agency to better identify the levels of methane emitted by Walleys Quarry. The removal of carbon dioxide compliance limits is standard across the landfill sector.
