Grid
Connection
The application
does not include a future off-site grid connection by National Grid.
Turbines would be connected to a control building/switching station
and then by underground cable 6 km to a proposed sub-station within
the Strathy South forest, where a future 78 turbine wind farm is proposed.
From there it will continue by underground cable a further 12 km to
connect into the existing Beauly to Dounreay 275kV tower line near the
Strath Halladale to Forsinard A897, through the Flow Country. (This
is like building a house with all services terminating at the edge of
the site. Planning Permission would not be granted without all service
connections being included in the application.)
Landscape
& Visual Amenity
This is an area
of Great Landscape Value. The proposed 7km square wind farm is situated
in a semi-mature conifer plantation, surrounded by internationally important
peatlands of high quality blanket bog, heathland and associated habitats
together with lochs, lochans, streams and the River Strathy. These Peatlands
are designated as a Special Protection Area (SPA), Ramsar Site and Special
Area of Conservation (SAC). The Peatlands extend east, west and southwards
from the site boundary. SSIs (sites of Special Scientific Interest)
surround all the forest boundaries.
This wind farm
will impact visually on numerous points over a wide area, extending
from Strathnaver, Bienna Mhadaid, Ben Griam Begg, Forsinard, Strath
Halladale, the settled North Coastal strip extending from Bettyhill
& Farr, towards Melvich, including Strathy Valley as well as parts of
Strathy, which would be adversely affected. The visual and landscape
impacts would be significantly detrimental and contrary to Policy G2
and Policy 4 in the Highland Structure Plan.
Noise
and Flicker
The noise implications
will be significantly detrimental, contrary to Policy G2 in the Highland
Structure Plan. The effect of noise has been misrepresented in the Environmental
Impact Assessment, which bases its reassurance on simple noise levels,
rather than assessing the complex noise pattern emitted by low frequency,
low-level aerodynamic and mechanical sound from gearbox, turbine and
blades. The claims that noise levels will be within night time limits
except for Braerathy Lodge, and that only Dallangwell will be at the
upper daytime limit, are questionable. Bowland Lodge and the village
of Strathy are not included, they might also be affected by shadow flicker.
Infrasound can be
detected at distances up to 10 km from a wind turbine. Although the
measurements might be small, the effect on peat stability and structures
within that radius, is still an unknown factor and no mitigating measures
have been put forward by the developer.
Ecology
The area is inhabited
by a large number of protected species, include Pine Marten, Wildcat,
Badger, Water Vole, Bats and Otters on the River Strathy, which is also
home to Atlantic Salmon and Brown Trout. Important Habitats are covered
in Annex 1 and Species in Annex 2 of the EC Habitats Directive, which
requires the establishment of a network of protected areas to ensure
conservation status of these habitats and species to be preserved intact.
There will be a
negative impact and disturbance of shelter and movement corridors of
protected species.
There will be an
impact on stream fauna and food sources.
There would be a
habitat change and an ecological change to the heathland, where the
foresty plantation is cleared, with a water table drawdown near the
cut faces in the peat for turbine foundations and tracks, including
floating tracks, within the wind farm site.
Birds
This development
would have an adverse impact on several European protected species and
qualifying interests of the Caithness and Sutherland Peatlands Special
Protection Area and Ramsar site and is therefore, contrary to policy
N1 of the Highland Structure Plan. Qualifying SPA species recorded were
Hen Harrier, Golden Eagle, Short-eared Owl, Merlin, Red-Throated Diver,
Black-Throated Diver, Golden Plover, Dunlin and Wood Sandpiper. In total
85 different species of birds were recorded on, near or flying over
the site. Birds of conservation concern recorded on the site include
14 red listed and 37 amber listed species. Of particular concern is
the impact on breeding Hen Harrier, Black-Throated Diver, Golden Plover,
Greenshank and Dunlin.
Geology
and Peat
This area forms
part of the Caithness & Sutherland Peatlands, one of the largest and
most intact known areas of blanket bog in the world, which should not
be destroyed. Peat depths vary from 0.1 to 4.5 metres, it dries out
at excavations and is likely to change into dry heath. Excavating for
turbine foundations, tracks and floating tracks, and watercourses for
the construction of a wind farm, will permanently damage the peat. It
is physically impossible to restore it once damaged. Restoration attempts
are going on at Forsinard by the RSPB, where trees have been felled,
but no wind farms are being constructed here. It has yet to be proved
by RSPB that it can be fully restored to blanket bog, not in our lifetime;
it will be a very long process, requiring maintenance far longer than
the 25 year lifetime of wind farms.
There is considerable
risk of peat slide. Strathy Forest is on the same blanket bog as the
rest of the area. When trees are felled, this puts slopes at risk of
peat slide, or peat instability, particularly should the construction
period coincide with dry weather followed by very wet weather. Turbine
foundations should not be sited on or near peat slopes. Turbines 1,
5, 9 and 17 are sited on slopes grossly exceeding 7% and turbine 34
is too close to the safe limit of 7%.
Destroying peat
adds to global warming. Peat stores 3 to 3.5 times as much carbon dioxide
as rain forests.
The hydrogeology
of the site will be affected. Below the peat the Precambian rocks are
impermeable, so there will be little capacity for storing the water.
The hydrology of
the whole catchment area of the River Strathy will be affected. Lochs
and private water supplies to Dallangwell and Bowland Lodge could also
be affected with the drying out of the site. There will be an increase
in silt, a risk of blocking watercourses and smothering of fauna and
flora with dust and debris during the construction period.
There will be permanent
scarring of the ground next to tracks from Borrow pits, i.e. new local
quarries.
Archaeology
The site contains
many archaeological remains. There are records of 2 archaeological sites
within the wind farm site, pre-clearance settlements at Dalangwell and
Braestrathy. One new site was discovered during the field survey. There
are extensive remains of medieval or later rural settlements, both deserted
and still occupied along the west bank of the River Strathy. There are
five archaeological sites within the proposed access corridor and at
Bowside. The whole area to the south was extensively settled, there
are one or more hut-circles on the east side of the river. More archaeological
sites may be discovered during the construction period.
Socio-economic
issues
Local employment
will be affected as it will impact on tourism and any new jobs would
only last for the length of the construction period, i.e. under one
year. There is no guarantee that local contractors would be employed.
Contractors outside the area may be employed by SSE, who also state
two people only would be sufficient to maintain it.
This proposed development
is contrary to Policy G1 of the Highland Council Structure Plan in that
it will not promote and enhance the social and environmental wellbeing
of the people of Strathy.
