Landfill: Difference between revisions

The landfill operator is required to continue to maintain monitoring and management of the site post-closure until it can be shown to the satisfaction of the EA that the active management of the site by the operator is no longer required. Assessment of such a state is measured against criteria identified in WMP 26A and subsequent EA guidance. It is generally accepted for non-hazardous landfill sites that this is unlikely to be able to shown for at least 60 years post-closure, probably somewhat longer.<br>

As the waste mass decomposes, the fill material settles under its own weight to occupy less volume. This process is known as '''settlement'''. The filling of the filling of the site is designed to achieve pre-agreed finals levels. These levels are agreed with the Planning Authority and it is usual to agree two sets of levels - one that represents the levels after the majority of the settlement has taken place and the other at an elevated level intended to represent teh level to which waste will be placed prior to settlement taking place. The difference between the two sets of levels is known as '''surcharge'''.
