13.3.86 A number of off-site licences are recorded within a kilometre of the site, the closest being a
licence for Local Authority Pollution Control, for general incineration processes under 1 tonne
an hour and a registered waste transfer site, with a maximum input of 10,000 tonnes per year
just outside the northwest of the application area. There is also a discharge consent for public
sewage and storm sewage approximately 180m southwest of the site.
Sensitivity of Receptors
13.3.87 On the basis of the baseline surveys and available information, Table 13.8 below identifies the
sensitivity of receptors as outlined in Table 13.3, with justification for their categorisation.

Surface Water
Water Quality
Black Devon High SEPA classification ‘Moderate’ but is a designated Salmonid River. Subject to
embankment protection along its lower course. Used for recreation, such as angling.
River Forth Medium SEPA classification of ‘Poor ecological status’ but is a designated Salmonid River.
Constructed embankments present along much of its lower course. Used for
recreation, such as angling. Tidal dominated by site boundary, large dilution
capabilities.
Groundwater Low The water quality of the groundwater body beneath the site has been classified as
Low with high confidence by SEPA.
Flood Risk
Flood Risk Medium Very limited areas of development fall within the flood inundation envelope (met
mast) but watercourses downstream of development have potential to flood.
Soils, Geology and Hydrogeology
Soils Low Much of the soil cover is expected to have been removed by the landfill in the southeastern
part of the site and the historical development in the north-western part of the
site. Soils do not support protected habitats; common to area as a whole.
Geology Medium Reserves of coal exist in the local area which could be worked at some time in the
future. Two coal adits are present in the north-eastern part of the site. The site is not

Key Issues
designated as a geological SSSI.
The superficial deposits are classified as an aquifer of limited potential and without
significant groundwater. Any groundwater resources in the superficial deposits may
already be impacted by the presence of the landfill at the site.
Groundwater in the bedrock is dominated by fracture flow, which offers very little
protection from pollutants.
The aquifers at the site vary in classification from Vulnerability Class 1 to Vulnerability
Class 3 in SEPA vulnerability classification scheme.
Landfill leachate and landfill gas will be disturbed during the excavations for turbine
foundations. The landfill cap will also be impacted during the excavations.
Localised disturbance of made ground may occur during construction.
There are no private water supplies identified within 3km of the site.
There are no public water supply pipelines identified at the site.
13.3.88 The following potential issues have been addressed as part of the assessment:
• pollution risk from disturbance and excavation of landfill material;
• risk of gas release from disturbance and excavation of landfill material;
• effects of excavation on landfill cap;
