[[Category:Non-Haz Landfill]]
==Summary==
[[Dunbar Landfill Site]] was developed by [[Blue Circle Waste Management]] and then [[Viridor]] from the early 1990s onwards. Blue Circle Waste Management were acquired by Pennon in 1995 and were renamed Haul Waste Disposal thereafter, subsequently becoming known as Viridor in 1999.
The site comprises a modern [[landfill]] engineered to Landfill Directive standards.

==History==
Dunbar landfill was developed by Blue Circle Waste Management commencing in the early-1990s. It is located to the 4 km to the south-east of Dunbar, East Lothian. It adjoins a cement works and quarry operated by Lafarge (formerly Blue Circle Cement). It is located between the A1 trunk road and the East Coast mainline railway and is within 500m of the coast.

The site was previously a quarry producing feedstock for the adjoining cement works.

[[Planning Permission]] for restoration by landfilling was granted in 1996, site operations commenced in 1997. This planning permission envisaged completion of landfilling and site restoration by 2020. Subsequently, in 2020, an application (20/00627/PM) was made that sought to extend the life of the landfill operations at the site until 2025. This application was approved in September 2020.

The [[Waste Management Licence]] was changed to an [[Environmental Permit]] in 2003/4 as required by the changing legislation at the time.

The capacity at the site as originally granted Planning Permission was circa xxxx cubic metres; this was subsequently increased upon approval of a revised [[Landfill Surcharge Allowance]] and set of [[Landfill Settlement Contours]] to around yyy cubic metres.

==Geology==
Prior to excavation of the quarry, the site was underlain by Quaternary-aged fluvio-glacial deposits comprising silts, sands and gravels. These are underlain by limestones of the Middle Skateraw Limestone, part of the Lower Limestone Group, which itself forms part of the Carboniferous Limestone Series sequence. The limestones are classified as [[Principal Aquifer]]. 

Mineral extraction at the site was principally the limestone of the Middle Skateraw Limestone. 

==Engineering and Environmental Controls==
The morphology of the site is a medium depth landfill within a steep sided quarry void.

The landfill is constructed as a Containment Facility, utilizing site-derived and imported clay materials as the principal barrier. The landfill lining system is augmented with a flexible membrane liner of High Density Polyethylene (HDPE) on the base and the sidewalls. 

There is [[Landfill Gas]] power generation with electricity export to the National Grid. Installed capacity is 5.25W.<ref>[https://renewablesandchp.ofgem.gov.uk/Public/ReportViewer.aspx? [[Ofgem]] Summary of Installed Capacity]</ref>

Leachate pumped from the landfill site is drained to two lagoons at the eastern end of the site. For many years, this has then been removed by road tanker for off-site disposal. In 2015, Viridor obtained planning permission (15/00022/PM) for an on-site treatment plant which would dispose of treated final effluent to the Dry Burn which runs along the eastern boundary of the site. It is unclear whether this plany has been constructed yet.

==Other Infrastructure==
Elsewhere within the site complex, Viridor have also developed several other waste processing facilities, including an internal waste transfer station (to enable road going vehicles to avoid driving on to the waste mass and also to act as a buffer store during windy weather conditions) and [[Dunbar EfW (Oxwellmains EfW)]], which will eventually take over for the landfill when it closes. The site is also rail-connected and wastes for landfill disposal were received from [[Edinburgh City Council]] by rail until the related contract ended in 2018/9.
