APCR Treatment and Disposal

FCC Environment is proposing to build an Air Pollution Control Residue (APCR) pre-treatment facility at Whisby Landfill off Eagle Road, Whisby. The APCR facility will safely treat the APCR that arises from the gas cleaning technology at the Lincolnshire Energy from Waste facility and other facilities.

What is APCR (Air Pollution Control Residue)?

Air Pollution Control Residue (APCR) is the fine powder that remains following the cleaning of the gases from Energy from Waste (EfW) facilities. The powder consists mostly of lime which is alkaline and consequently APCR is classified as hazardous waste and must therefore be pre-treated and neutralised before being disposed of in a specially constructed hazardous landfill mono-cell. The term mono-cell refers to a separate, specially engineered landfill cell solely for the disposal of hazardous wastes. This is because the regulations prevent the co-disposal of hazardous and non-hazardous wastes and it is therefore necessary to keep them separate.



Why is an APCR Facility needed at Whisby?

The primary purpose of the proposed facility is to pre-treat APCR from the Lincolnshire EfW facility in preparation for disposal. The existing Whisby landfill site is the most suitable site locally for the final disposal of pre-treated APCR as the site already benefits from planning permission that allows for the disposal of this type of material and is already an active landfill site.
 
The facility is required in order to pre-treat APCR prior to its disposal.  The pre-treatment of this hazardous waste is required so that it meets waste acceptance limits specified by the Landfill Regulations.  Developing the treatment facility and landfill cell on the same site reduces vehicle movements that would otherwise be generated if the treatment facility was located at another location.



How does the process work?

The APCR would be transported to the site in sealed powder tankers before being transferred by pipe directly into an enclosed storage silo. Once within the silo, residues are conveyed into a unit where the material is hydrated/treated with a combination of either water or acid to reduce its alkalinity and may also be mixed with stabilising materials such as cement or pulverised fuel ash (PFA) from power stations, depending upon its composition and treatment requirements. Following treatment the material would then be loaded onto dedicated site vehicles for disposal in specifically constructed landfill mono-cells.

The treatment process is designed to reduce the hazardous nature of the APCR to meet the hazardous waste acceptance criteria and to stabilise it ready for landfill disposal. The treatment applied to the APCR results in a material similar in nature to a concrete mix, and it sets shortly after being placed in the landfill mono-cell. Due to the nature of the concrete-like-state of the treated material there is no potential for the usual amenity issues such as odour, litter, vermin etc. that are commonly associated with landfill sites.



How is the waste disposed of?

The treated APCR will be disposed of within a fully engineered mono-cell to be developed at the existing Whisby landfill site.

The site currently has planning permission for landfill disposal (there are no restrictions on waste types under this permission) and also has an environmental permit for the disposal of non-hazardous wastes. FCC Environment will be applying to the Environment Agency to vary the current environmental permit to allow for the acceptance of APCR. FCC Environment safely operates a number of other hazardous mono-cells for the disposal of APCR in the UK.

Would there be any environmental or amenity impacts?
An Environmental Impact Assessment (EIA) will be undertaken in support of the planning application for the APCR pre-treatment facility. This will consider whether the proposed development has the potential to give rise to any significant environmental effects. The scope of the assessment was discussed and agreed with Planning Officers at Lincolnshire County Council.  As a result, the statement will consider the effects of the development in terms of:

    Air Quality (including Dust and Odour)
    Ecology and Nature Conservation
    Noise
    Landscape and Visual effects
    Traffic and Transportation

The EIA concluded that the proposed development will not give rise to any significant effects on the environment or public amenity.

In addition to the assessment of potential impacts through the planning process it must also be noted that once the APCR pre-treatment and stabilisation facility is constructed and operational, it will be controlled and regulated by an Environmental Permit, issued and regulated by the Environmental Agency.



Will there be dust or odours from the APCR facility?

Due to the nature of the APCR, the potential for odour is extremely limited. Amenity issues are considered further in the planning and environmental permit applications for the proposed facility. Once operational, amenity issues would be controlled through the site's Environmental Permit which will be regulated by the Environment Agency.



 Will the process be noisy?

FCC Environment operational experience gained at other facilities confirms that the proposal would generate limited noise. The location of the proposed facility and limited process equipment is within an enclosed clad structure, which would further reduce the potential for noise. For this specific facility, a noise impact assessment has been completed and submitted with the planning application.



What will the visual impact be?

Due to the location of the proposed facility within the wider Whisby landfill site, the limited extent of the built development and the presence of existing, mature vegetation, it is not considered that the proposal would generate any visual impacts. A landscape and visual assessment is included within the planning application.



What will the traffic impact be?

Waste delivery vehicles are already permitted under the current planning permission for the landfill site. The proposed facility would not create additional vehicle movements over and above that permitted by the current planning consent. The introduction of the proposed development is simply to provide pre-treatment of waste prior to disposal and will enable the site to be restored in accordance with the approved landfill restoration scheme. The development of this facility would not create any additional traffic that would not have potentially been visiting the site to dispose of other waste types that do not require pre-treatment.



 What happens next?

The pre application public consultation period has now concluded and the application was submitted in October 2011. Planning Officers at Lincolnshire County Council will review the application and all the feedback from the public and statutory stakeholders (such as the Environment Agency and Health Protection Agency). Following this review a report will be prepared and presented to members of the Planning Committee at Lincolnshire County Council who will make a formal decision as to whether to approve or reject the application.
