SITA UK has submitted a Proposal of Application Notice (PAN) to Aberdeenshire Council outlining its proposal to amend the closure date of Stoneyhill landfill site.
SITA UK proposes that tipping be allowed to continue at the facility for a further 12 years, from June 2012 to December 2024.
At current input rates, it will take this long for the existing permitted void to be filled and the approved final restoration levels to be reached.
The total amount of waste deposited at the site will not increase and there are no other changes to the existing permitted scheme.
Annemarie Wilshaw, Planning Manager for SITA UK, said: "Landfill still has an important part to play in managing waste as recycling rates increase and alternative sustainable facilities are introduced in Scotland.
"Amending the end date of this site will mean the permitted space will be filled as planned and Stoneyhill landfill will continue to take non-recyclable waste from the residents of Aberdeen City, Aberdeenshire and the Highlands."
As part of the pre-application consultation process, SITA UK will be holding two public exhibitions in mid-June to enable residents to look at the plans in detail, ask questions and voice their views.
Wider plans for a proposed resource recovery park at Stoneyhill, incorporating a mechanical biological treatment (MBT) facility and gasification plant, will also be on show. Further details about the exhibitions will be released nearer the time.
SITA UK will then submit two separate planning applications to Aberdeenshire Council, one for the landfill closure change and a separate one for the resource recovery park, sometime during the summer.
The plan is in line with the Scottish Government’s Zero Waste Plan, which still envisages a role for landfill for waste that cannot be recycled or treated.
