Landfill: Difference between revisions

Line 162:

Gas and leachate extraction and monitoring equipment (such as monitoring well and pipework) commonly penetrates the capping and soil layers in order to afford access for maintenance and monitoring. Sometimes this equipment is progressively buried with suitable access points remaining at the surface; this is done principally for aesthetic reasons to improve the appearance of the final restored surface.

Landfill sites where all tipping has ceased and the all infrastructure for post-closure management has been installed are deemed "closed" following agreement with the [[EA]].

Landfill sites where all tipping has ceased and the all infrastructure for '''post-closure''' management has been installed are deemed "closed" following agreement with the [[EA]].

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 WMP26A<ref name="refA" /> 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. This period is known as the '''aftercare''' period.

* to indicate whether further investigation is required and, where the risks are unacceptable, the need for measures to prevent, reduce or remove pollution by leachate;

* to identify when a site no longer presents a significant risk of pollution or harm to human health (to enable an application for a certificate of completion to be made, and thereby formally end the licensing or permitting process and the legal duty to monitor).
