The Environment Agency and the Environmental Permit require the ongoing management and phased restoration of a landfill site operated by Durham County Council. This will involve the development of a permanent cap over the existing uncapped areas of previous waste placement, extending the existing gas management scheme and developing a scheme for the long term management of surface water from the site as a whole.

As part of Durham County Council’s waste strategy, the appointment will include:-
