1.0 INTRODUCTION
This Ecological Impact Assessment (EcIA) report provides an assessment of the potential
impacts of the proposed Single Wind Turbine and proposed grid connection route on the flora,
fauna and biodiversity of the site and surrounding area. This assessment has been undertaken
by Doherty Environmental Consultants (DEC) Ltd on behalf of ART Ltd. and examines the
potential ecological impacts of the proposed Single Wind Turbine.
The purpose of this assessment is to:
• identify the habitats of the site
• identify the existing sensitive fauna of the site
• identify the potential impact of the proposed development
• recommend measures to mitigate probable impacts
• identify any residual impacts to the site’s ecology
The scope of the following assessment follows the guidance outlined in the CIEEM’s
Guidelines for Ecological Impact Assessment (2018); TII Guidelines for Ecological
Assessment of National Road Schemes; and the EPA guidance document Guidelines on the
information to be contained in Environmental Impact Assessment Reports (2022).
The following impact assessment is based upon a review of existing desktop information and
the results of on-site field surveys, details for which are provided below.

1.2 Relevant Legislation & Guidance
1.2.1 LEGISLATION
1.2.1.1 EU Habitats Directive 92/43/EEC, European Communities (Natural Habitats) Regulations
1997, European Communities (Birds and Natural Habitats) Regulations 2011
The Habitats Directive provides the basis of protection for Natura 2000 sites, namely Special
Protection Areas (“SPAs”) and Special Areas of Conservation (“SACs”). Article 6 of the EU
Habitats Directive requires that any proposal that may have a significa nt effect on a Natura
2000 site must be subject to an Appropriate Assessment. An Appropriate Assessment is
required in order to ascertain the potential impact of a proposal on the reasons for which the
site is designated, and thereby ascertain the potential for adverse impact on the integrity of the
site. A proposal that may adversely impact the integrity of the site may not be consented except
in the absence of Feasible Alternative Solutions and in the event of Overriding Public Interest.
A Natura Impact Statement has been undertaken for the proposed EIA Development. This
concludes that the proposed EIA Development will not, adversely affect the integrity of any
European Site (Natura 2000 site), either directly, indirectly or cumulatively.
The Habitats Directive also provides for the protection of species listed under Annex IV of the
Directive wherever they occur. These species include otter and all bat species.
The Habitats Directive was transposed into Irish law by the European Communities (Natural
Habitats) Regulations 1997 and subsequently amended in the European Communities (Birds
and Natural Habitats) Regulations 2011. Regulation 42 of the 2011 regulations requires that
any proposal likely to have a significant effect on a European Site, alone or in combination with
other operations or activities, needs to be assessed with respect to its potential impact in the
site’s conservation objectives (an Appropriate Assessment) and that the decision-making
authority should be furnished with a Natura Impact Statement that incorporates a Screening
Assessment and Appropriate Assessment as necessary. RECEIVED: 07/10/2025

1.2.1.2 Environmental Impact Assessment Directive (2011/92/EU)
European Union Directive 2011/92/EU (“the EIA Directive”) considers the assessment of the
effects of certain public and private projects on the environment. It has been transposed to Irish
legislation by the Planning and Development Act 2000 (as amended), and the Planning and
Development Regulations (2000 – 2015) (hereafter referred to as the “2011 EIA Regulations”).
The Planning and Development Act 2000 (as amended) Part X, Section 171A (1) requires that
an EIA is carried out by the competent authority (i.e. the local planning authority or An Bord
Pleanála):
“that shall identify, describe and assess in an appropriate manner, in light of each individual case
and in accordance with Articles 4 to 11 of the Environmental Impact Assessment Directive, the
direct and indirect effects of a proposed development on the following:
(a) human beings, flora and fauna….,”
1.2.1.3 Environmental Impact Assessment Directive (2014/52/EU)
The requirements of the revised EIA Directive (2014/52/EU) (“the Revised EIA Directive”),
which will be incorporated into Irish law, are taken into account by the observance of draft
Revised Guidelines on the information to be contained in Environmental Impact Statements1.
Annex IV of the Revised EIA Directive provides requirements for information to be included
in the EIAR (as referred to in Article 5(1)(f). Additional emphasis has been placed on
‘biodiversity’ in the 2014 EIA Directive (see Section 1: Introduction of this REIS / EIAR for
further details).

1.2.1.4 EU Birds Directive 79/409/EEC
EU Birds Directive 79/409/EEC ("the Birds Directive”) establishes a system of general protection
for all wild birds throughout the European Union. Annex I of the Birds Directive comprises 175
bird species that are rare, vulnerable to habitat changes or in danger of extinction within the
European Union. Article 4 establishes clearly that wherever those species occur, they should be
the subject of special conservation measures concerning their habitat in order to ensure their
survival and reproduction in the area of distribution. Similar actions should be taken by Member
States regarding migratory species, even if they are not listed in Annex I.
1.2.1.5 Bern and Bonn Convention
The Convention on the Conservation of European Wildlife and Natural Habitats (Bern
Convention 1982) exists to conserve all species and their habitats. The Convention on the
Conservation of Migratory Species of Wild Animals (Bonn Convention 1979, enacted 1 983)
was instigated to protect migrant species across all European boundaries.
1.2.1.6 The Wildlife Act (1976) as amended (2000)
The Wildlife Act 1976 gives protection a wide variety of birds, animals and plants in the
Republic of Ireland. It is unlawful to disturb, injure or damage to their breeding or resting place
wherever these occur without an appropriate licence from National Parks and Wildlife Service
(“NPWS”). All birds, their nests and eggs are protected under law in Ireland through the
Wildlife Act 1976 (as amended in 2000). Wilful destruction of an active nest from the building
stage until the chicks have fledged is an offence. The act also provides a mechanism to give
statutory protection to Natural Heritage Areas (“NHAs”). The amendment in 2000 broadens
the scope of the Wildlife Acts to include most species, including the majority of fish and aquatic
invertebrate species which were excluded from the 1976 Act.
1.2.1.7 Flora (Protection) Order, 1999
The Flora (Protection) Order affords protection to listed vascular plants, mosses, liverworts and
stoneworts. It is illegal to cut, uproot or damage the listed species in any way, or to offer them
for sale. This prohibition extends to the taking or sale of seed. In addition, it is illegal to alter,
damage or interfere in any way with their habitats. This protection applies wherever the plants
are found and is not confined to sites designated for nature conservation. RECEIVED: 07/10/2025

1.2.2 SCHEDULE OF WORKS
DEC Ltd. was commissioned to undertake an Ecological Impact Assessment of the proposed
Single Wind Turbine at Carney’s Island Clones and associated grid connection route. A desktop
survey was undertaken to gather existing baseline information for the proposed development
site and surrounding area.
A range of on-site field surveys were completed to inform the baseline biodiversity conditions
at and surrounding the proposed development site.
Field surveys were completed at the project site to inform this screening report for Appropriate
Assessment. The field surveys included targeted vantage point surveys and winter and breeding
bird season transect surveys.
Habitat surveys were also completed and particularly attention was given to recording the
presence of surface water pathways in the form of watercourses or surface drains. .
The vantage point surveys comprised watches from a vantage point that provides a view of the
proposed turbine location and the wider surrounding area. The vantage points were completed
during the 2023 and 2024 breeding season, and the 2023/2024 non-breeding season on the 26th
April 2023; 14th June 2023; 12th October 2024; 7th February 2024; 1st May 2024; 9th May 2024;.
A watch of 3.5 hours was completed during each of the vantage point surveys amounting to a
total of 21 hours vantage point surveying of the proposed turbine location and wider
surrounding area.
Subsequent to the termination of each vantage point watch, walked transect surveys were
completed within the fields at and adjacent to the proposed turbine location and access track.
The location of the vantage point and the bird transects are shown on Figure 1.3..

management as well as relevant statutory and non-statutory agencies. In addition to the above
the following research was also undertaken:
• A review of the National Biodiversity Data Centre (NBDC) to identify the presence or
otherwise of protected species occurring within close proximity to the proposed site .
The area of search for records of rare, threatened or protected is shown on Figure 2.1
below.
• A review of the NPWS online database to identify the presence or otherwise of
designated conservation areas (i.e. SPAs, SACs, NHAs etc.)
• A review of Site-Specific Conservation Objectives (SSCO) mapping, published by the
NPWS, for SACs and SPA.
• A review of the online BCI Batlas
• A review of the New Atlas of the British and Irish Flora (Preston et al., 2002)
• A review of the New Atlas of Breeding Birds in Britain and Ireland: 2007 – 2011

2.2 Site Investigations
2.2.1 HABITAT SURVEYS
Habitat surveys were carried out on the 26th April 2023 and again on the 9th May 2024. Habitat
surveys were carried out to identify, describe, map and evaluate habitats and to verify
information gathered at the desk study stage. The basis of the surveys undertaken on the above
dates was an “Extended” Habitat Survey. This habitat survey was undertaken in accordance
with the Heritage Council Draft Best Practice Guidance for Habitat Survey and Mapping. The
National Vegetation Classification (NVC) User’s Handbook also informed the approach to the
habitat surveys. Habitats were classified using Fossitt’s Guide to Habitats in Ireland (2000)
which classifies habitats according to a hierarchical framework with Level 1 habitats
representing broad habitat groups, Level 2 representing habitat sub-groups and Level 3
representing individual habitats. The field survey focused on identifying Level 3 habitats.

The DAFOR scale was used to characterise the vegetation within each habitat. This scale refers
to plant species in terms of dominance, abundance, frequency, occasional and rare (DAFOR).
In this report, scientific and common names for higher plants follow those in the Botanical
Society of the British Isles (BSBI) standard list, published on its website www.bsbi.org.uk.
Scientific and common names for bryophytes follow Smith (2004). Scientific and common
names of mammals follow Whilde (1993).
2.2.1.1 Non-volant Mammal Survey
The mammal survey involved walking either side of hedgerows and other field boundaries,
along the Legarhill Stream and through recently felled woodland, recording any field signs of
mammal activity. These field signs, as described in Neal & Cheeseman (1996) and Bang &
Dahlstrom (2006), include:
• mammal breeding and resting places, such as setts, holts, lairs
• pathways
• prints
• faecal deposits
• latrines (and dung pits used as territorial markers)
• feeding signs (snuffle holes)
• hair; and
• scratch marks
During these surveys particular attention was given to search the Legarhill Stream crossed by
the proposed access track for field signs indicating the presence of otters and their breeding
and resting places (i.e. holts and couches).
2.2.2 BIRD SURVEYS
2.2.2.1 Vantage Point Surveys
The methodology adopted for the vantage point surveys was derived from the Scottish Natural
Heritage (SNH) guidance document Recommended bird survey methods to inform impact
assessment of onshore wind farms (2017). These guidelines outline specific survey
methodologies for undertaking surveys to assess the potential impact of wind farms to
lowland/farmland species. With regard to smaller scale developments such as Single Wind
Turbine projects, the SNH guidelines state: RECEIVED: 07/10/2025

Smaller developments and even single turbines may also present a potential risk if placed in
areas of high bird sensitivity, particularly on or near SPAs. Survey effort and assessment of the
possible impacts of a proposed wind farm on birds should be in proportion to the scale of the
wind farm and the bird interest in the area. A number of small scale developments will either
not require an EIA or, if they are only just over the thresholds, require a limited environmental
assessment. Typically, these very small developments (including ‘domestic’ turbines of 15m or
less) are not considered to be a significant risk to birds, exceptions to this being proposals on
or near designated sites, or where the location is very close to the nest site of a Schedule 1 bird.
Assessment of existing bird data for the area may be all that is needed in many of these cases
and simple mitigation such as relocating the turbine further away from a designated site or a
Schedule 1 bird nest site may be sufficient to overcome any issue s without the need for further
survey.
Due to the small scale of the proposed development with only one turbine included, the SNH
recommended level of survey (which typically involves 36 hours of vantage point watching per
vantage point per season) for this assessment has been scaled down to reflect the limited scale
of the proposed development.
SNH guidance for surveys at wind farms recommend that field surveys focus on those species
of high nature conservation value for which there is potential for impacts to occur. These target
species tend to be limited to those species of conservation concern, which as a result of their
flight patterns or response behaviour are considered to be susceptible to either displacement
due to wind turbine operation or collision with turbine blades.
Bird surveys involved vantage point surveys and a transect survey through the project site. The
vantage point surveys comprised watches from a vantage point that provides a view of the
proposed turbine location and the wider surrounding area. The vantage points were completed
during the 2023 and 2024 breeding season, and the 2023/2024 non-breeding season on the 26th
April 2023; 14th June 2023; 12th October 2024; 7th February 2024; 1st May 2024; 9th May 2024;.
A watch of 3.5 hours was completed during each of the vantage point surveys amounting to a
total of 21 hours vantage point surveying of the proposed turbine location and wider
surrounding area.

2.2.3 BATS
The suitability of the project site to support bats was evaluated by reviewing the bat landscape
favourability model (Lundy et al. 2011) and appraising the habitats occurring within the site or
their potential to support foraging bats. This latter appraisal was completed with reference to
the foraging habitat preferences of bats, as detailed by Collins et al. (20 23) and the SNH (2019)
guidance for appraising the habitat risk for bats.
Bat activity surveys were completed during the 2024 bat activity season. One round of bat
activity survey was completed. The activity surveys were based on continuous automatic bat
detector surveys undertaken during the 2024 bat activity season between the 1st May and 11th
9th May over a period of 9 consecutive nights. The automatic bat detector survey was
undertaken using a Song Meter Mini Full Spectrum Ultrasonic Bat Detector. The detector was
positioned at one monitoring station (MS) adjacent to the proposed turbine location along the
edge of the recently felled conifer plantation. The location of the monitoring station is shown
in Figure 2.2. The bat detector was mounted on a pole at a height of 3m.
The Song-Meter was set to record continuously throughout each night of monitoring. Recording
commenced 30 minutes before sunset and terminated 30 minutes after sunrise.
Analysis of bat calls recorded during the activity surveys was undertaken using Kaleidoscope
software.

2.2.4 TERRESTRIAL MAMMALS
The mammal survey involved walking either side of hedgerows and along drainage ditches and
recording any field signs of mammal activity. The mammal survey was completed during the
July habitat survey. These field signs, as described by Neal & Cheeseman and Bang &
Dahlstrom (2006) include:
• Mammal breeding and resting places, such as setts, holts and lairs
• Pathways
• Prints
• Faecal deposits
• Latrines (and dung pits used as territorial markers)
• Feeding signs (snuffle holes)
• Hair and Scratch marks
2.3 Site Evaluation
The nature conservation value of habitats and ecological sites occurring within the proposed
site are based upon an established geographic hierarchy of importance as outlined by the
National Roads Authorities (NRA, 2009). The outline of this geographic hierarchy is used to
determine ecological value in line with the ecological valuation examples provided by the NRA
(see NRA, 2009). The geographic evaluation hierarchy is as follows:
• International Sites (Rating A)
• National Importance (Rating B)
• County Importance (Rating C)
• Local Importance (higher value) (Rating D)
• Local Importance (lower value) (Rating E)
2.3.1 BIRDS
The bird assemblage recorded at the proposed development site is valued with regard to the
ecological valuation examples set out in Guidelines for Assessment of Ecological Impacts of
National Roads Schemes: Revision 2 (2009). RECEIVED: 07/10/2025

The evaluation of the avifauna recorded at the project site during the baseline surveys is also
informed by the approach detailed by Percival (2003). This approach defines the sensitivity of
a species and bird assemblage as the ecological importance and nature conservation interest at
the site being assessed. The ecological importance and nature conservation interest is
determined by a number of factors including:
• whether the species is on Annex 1 of the EC Birds Directive
• whether the area being assessed is subject to any nature conservation designations
• whether the species is particularly ecologically sensitive: this includes larger birds of
prey and rare breeding birds (including divers, common scoter, hen harrier, golden
eagle, red-necked phalarope, roseate tern and chough)
• whether the site contains species at nationally important numbers (>1% of Irish
population)
• whether the site contains species at regionally important numbers (>1% of regional
population, with the region usually taken as the county)
• whether the species is subject to special conservation measures, e.g. as Red or Amber
species on the BirdWatch Ireland’s (Newton et al. 1999) list of Birds of Conservation
Concern.
The determination of sensitivity is summarised, as per Percival (2003), in Table 2.2 below:

The approach outlined by Kepel (2011) to quantifying bat activity has been used to evaluate
the level of bat activity recorded at and surrounding the proposed development site and the
importance of the proposed development site and surrounding area as a foraging resource for
bats.
The Kepel approach is based on assigning the number of bat passes recorded per hour per night
of each monitoring session to an activity category. Kepel has assigned the number of passes
per hour to three activity categories. These activity categories are as follows: RECEIVED: 07/10/2025

• Pipistrelle species and Leisler's bat: Low = <3.5 passes per hour; Moderate = 3.6 – 6.5
passes per hour; High = >6.5 passes per hour.
• All Other Bat species: Low = <4.0 passes per hour; 4.1 to 10 passes per hour; high =
>10 passes per hour.
The median bat pass per hour per night for each species recorded during bat activity surveys
has been used to assign bat activity levels in line with the Kepel approach. Median bat pass per
hour per night is used during this analysis as it is recognised as providing a more accurate
representation of activity, as bat activity levels between nights can be highly variable and thus
the median provides a more reliable value that the mean or maximum (Lintott & Matthews,
2018).
2.3.3 NON-VOLANT MAMMALS
The nature conservation value of non-volant mammal populations recorded during field surveys
has been assigned in accordance with the criteria set out by the TII 2009 guidance document.
2.4 Impact Assessment Methodology
2.4.1 IMPACT MAGNITUDE
Impact magnitude refers to changes in the extent and integrity of an ecological receptor. The
CIEEM (2006) defines integrity of designated conservation areas as “the coherence of the
ecological structure and function across the area that enables it to sustain the complex of habitat
and/or the levels of populations of the species for which it was classified”. For non-designated
sites this can be amended to: “the coherence of ecological structure and function, that enables
it (the site or populations supported by the site) to be maintained in its present condition”. For
the purposes of this assessment the impact magnitude is influenced by the intensity, duration,
frequency and reversibility of a potential impact and is categorised as follows:
• High magnitude impact: that which results in harmful effects to the conservation status
of a site, habitat or species and is likely to threaten the long-term integrity of the system.
• Moderate magnitude impact: that which results in harmful effects to the conservation
status of a site, habitat or species, but does not have an adverse impact on the integrity
of the system. RECEIVED: 07/10/2025

DEC Ltd. 7 07/07/2025
• Low magnitude impact: that which has a noticeable effect but is either sufficiently
small or of short duration to cause no harm to the conservation status of the site, habitat
or species.
• Imperceptible: that which has no perceptible impact.
• Positive: that which has a net positive impact for the conservation status of a site,
habitat or species.
2.4.2 IMPACT SIGNIFICANCE
The significance of impacts is determined by evaluating the nature conservation value of the
site, habitat or species concerned together with the magnitude of the impacts affecting the
system. The more ecologically valuable a receptor and the greater the magnitude of the impact,
the higher the significance of that impact is likely to be. Table 2.3 outlines the levels of impact
significance to be used during the assessment of impacts. The probability of an impact
occurring will also be outlined when defining the significance of impacts.

2.4.3 IMPACT ASSESSMENT – BIRDS
The sensitivity of a species is defined by evaluating its ecological importance and nature
conservation interest. Species sensitivity is ranked on a scale from very high to low. The criteria
used to rank species sensitivity is outlined in Table 2.4.

2.4.3.1 Impact Magnitude
Once the species/populations in the study area have been evaluated in terms of their sensitivity,
the next step is to determine the magnitude of the possible impacts that may occur on those
species/populations. The impact magnitude is based on the scale of loss or alteration to key
elements/features of the baseline conditions. Impact magnitude is ranked on a five -point scale
from very high to negligible. Table 2.5 outlines the criteria for determining the impact
magnitude of wind farm developments.

3.2 Wind Turbine
The proposed wind turbines will be a Nordex N133 on a 71.5m tower and will have a maximum
tip height of 143.8m. A drawing of the proposed wind turbine is shown on Drawing No. 22790 -
200 & 201.
The turbines installed on the site will be the conventional three -bladed, tubular tower model
with horizontal axis. The rotor blades are bolted to the central rotor hub, which is connected to
the nacelle. The nacelle contains the following turbine components:-
• Generator
• Electrical components
• Aviation lighting to Irish Aviation Authority (IAA) specifications.
The entire nacelle and rotor are designed to rotate, or ‘yaw’, in order to face the prevailing
wind. A wind vane located on the nacelle of the turbine controls the yaw mechanism. A control
unit is typically located at the base of the turbine and an internal lift or ladder leads up to the
nacelle where the shaft, generator and gearbox are located.
The turbine tower is a conical steel tube with multiple layer paint finish. Towers comprise a
steel ring at the base of the tower which is assembled on top of the concrete foundations. The
tower will be delivered to site in three sections. The base of the tower is approximately 4.3m in
diameter, tapering to approximately 3.2m where it is attached to the nacelle. The tower is
accessed by a galvanised steel hatch door, which will be kept locked except during
maintenance.
The blades of the turbines are typically made of fibreglass or carbon fibre reinforced polyester
and are aerodynamically shaped to improve efficiency and lower noise production.
The turbines are multi-ply coated to protect against corrosion. It is proposed that the turbines
will be of an off-white or light grey colour to blend into the sky background RECEIVED: 07/10/2025

3.3 Turbine hardstand
The crane Hardstand will be constructed to accommodate and support the Wind Turbine
components, cranes and other plant during delivery and Turbine erection. Hardstands will also
be used for maintenance activities while the Wind Turbines are in operation.
The dimension of a single Hardstand is circa 91 metres in length and 35 metres in width. There
will also be smaller temporary stoned areas constructed to store the Wind Turbine parts and
components prior to erection, these will be removed, and the areas reinstated on completion of
the Wind Turbine erection. See Planning Drawing 22790-202 for details on the Hardstand.
The crane Hardstands will be constructed to support the significant loads imposed by the
outriggers of the main lifting crane during the Wind Turbine installation process on site.
Hardstand construction will include the following:-
1. The excavation process will involve hydraulic excavators moving excavated material to on -site
repository areas using articulated dumper trucks or tractor and trailers.
2. Topsoil will be excavated in the presence of the Archaeologist and removed to the temporary
topsoil repository area for use in the permanent reinstatement works.
3. The Hardstand formation will be formed by excavating subsoil to a suitable bearing stratum in
accordance with the requirements of the Design Engineer.
4. The Hardstand will be constructed using imported stone aggregate rolled in layers and tested in
accordance with the requirements of the Design Engineer.
5. Temporary set down areas will be created at each crane Hardstand to store Wind Turbine
components such as the rotor hub assembly, turbine blades, turbine towers, and nacelle. These
areas will be made of compacted stone aggregate, these will be removed and the areas reinstated
on completion of the Wind Turbine deliveries.
6. Plate bearing tests will be conducted on the completed Hardstand surface to verify if the
Hardstand bearing strengths meet the crane outrigger load requirements. RECEIVED: 07/10/2025

7. The main crane outrigger areas are subjected to the highest levels of stress and as such strict
minimum requirements are put in place to ensure safety during the works. This includes but is
not limited to:
a. Surface Evenness of equal or less than 0.25% slope.
b. Minimum Bearing Capacity of 220kN/m2.
3.4 Substation
It is proposed to construct a 20kV electricity Substation within the site boundary as shown on
Drawing No. 22790-102. This Substation will provide a connection to the national grid via an
underground 20kV transmission cable connection.
The construction and electrical components of the on-site Substation will be to ESB, Electrical
Designer and Wind Turbine Supplier specifications.
The Substation compound will have an area of approximately 256m2 and will include one
Substation building and electrical components. The Substation and compound will be
surrounded by stockproof fencing.
Prior to construction beginning, interception drains will be placed uphill from the planned
Substation area to catch any current overland water flows and direct them downhill to minimise
water contact with the construction site. The clean water will be released through a level
spreader downhill from the construction site, flowing over the current vegetation.
The construction will include the following:-
1. The Substation compound's area will be outlined using ranging rods or wooden posts.
2. Perimeter drains will be installed or upgraded to collect surface water run-off from the
Substation compound. This will involve the installation of check dams, silt traps and level
spreaders to manage surface run-off effectively.
3. Topsoil will be stripped and carefully stockpiled for future landscaping use. RECEIVED: 07/10/2025

4. Subsoil will be excavated and retained on site by incorporated it into the perimeter of the
compound area.
5. The Substation compound will be formed by constructing compacted layers of suitable
hardcore;
6. The foundations for both Substation buildings will be excavated down to the level indicated by
the designer and appropriately shuttered;
7. Steel reinforcement will be laid in place and concrete foundations will be poured;
8. The Substation building will be constructed on top of the concrete foundations.
9. Construction of underground cable ducts and trenches within the Substation compound will be
carried out;
10. On completion of the ground works the area will be re-topsoiled and landscaped;
11. Stockproof fencing and gates will be installed around the compound perimeter on completion
of the landscaping works.
3.5 Grid Connection
The turbine will connect directly to the national electrical grid network at the approved
substation. The grid connection route is not included as part of this planning application but is
assessed as part of the Planning and Environmental Report. The grid connection is via circa
1.9km of underground 20kV electrical cabling connecting to Clones 38kV Substation in the
townland of Clones, County Monaghan. The majority of the grid connection will be constructed
in public road verges and footpaths.
3.6 Turbine Delivery Route
The components for the Wind Turbines will be delivered by cargo ships to the Port of Waterford,
which is also known as Belview Port, and is actually located in County Kilkenny. The
components for the Wind Turbine will be delivered in separate loads, some of which are abnormal RECEIVED: 07/10/2025

in terms of their width and length. The components will be transported from Belview to the site
along the motorway, national, regional and local road network.
Several junction locations along the national road and both bends and junctions on the regional road
network require temporary works to accommodate these deliveries of Wind Turbine components
to the site, as well as construction works at the site access on the R183. These works will include
the temporary alterations at locations on the N54 and the R183.
This will include the temporary hardstanding’s, making signposts, lighting columns and kerbs
demountable / hinged, utility diversions, minor drainage works (i.e. temporary relocated
interceptor ditches) hedgerow / vegetation cutting for oversail.
At construction stage a transportation plan will be prepared by the Wind Turbine component delivery
company. Permits for moving the abnormal loads on the public roads to the Wind Farm site will
be obtained from An Garda Síochána and the applicable local authorities on the selected haulage
route.
The selected haulage route is detailed below:
• Starting at Belview Port;
• Turn Left, then the next right onto the N29;
• Merge onto the N29;
• At the Slieverue Roundabout, exit to stay on N29 going Northbound;

3.7 Site Drainage
Clean water cut-off drainage will be installed up-hill or up-stream around the perimeter of the
proposed work areas as part of the Enabling Works. This drainage “cuts-off” existing drainage
runs from entering the proposed work areas thus reducing site surf ace water run-off, prevent
soil erosion, and protect the water quality downstream. This drainage will be temporary and
on completion of the site works it will be removed or altered and incorporated into the
permanent works drainage.
Permanent drainage will be constructed during construction of the Access Roads, Hardstands,
Turbine Foundations, Substation. While construction works are being carried out, this drainage RECEIVED: 07/10/2025

tends to pick-up a suspended solids – and is often known as “dirty water”. During the
construction stage, this dirty water drainage is directed to a number of sediment control
measures such as check dams and settlement ponds. The permanent drainage during the
construction stage is therefore often referred to “dirty water cut-off drainage”.
Plate 3.1 below shows a typical check dam arrangement. The site's proposed drainage system
is detailed in Planning Drawings 22729-130 to 22729-134, provided under separate cover with
the planning application documentation.
Plate 3.1: Check Dam
The drainage design will incorporate the following:-
1. Check dams strategically positioned at regular intervals along all drains to slow down flow,
encourage settlement, prevent scour and ditch erosion, and prevent silt from reaching adjoining
drainage channels.
2. Low gradient drains will be installed. These slow down the flow rate in the drains, which
decreases soil and subsoil erosion and reduces the amount of water entering watercourses. RECEIVED: 07/10/2025

3. Existing drains will be preserved where applicable.
4. Regular buffered outfalls will be installed. These are composed of several minor drains
branching from the main drain and terminating by spreading out into the nearby vegetation
through tapered drains. The drain will have hardcore material to capture suspended sediment.
5. Construction site runoff will be redirected into settlement ponds to encourage sediment
deposition and decrease hydraulic loading by lowering flow velocities, enabling sediment to
settle. The settlement ponds are structured as a three-stage tiered pond system. The settlement
pond system design for the site is outlined in Planning Drawing 22729-102 & 103.
6. Water from the settlement ponds will flow into the sediment traps for additional cleaning
through a sequence of graded gravel filters.
7. Drainage ditch outfalls from silt traps will release water periodically to imitate natural
hydrology, promoting percolation and reducing hydraulic loadings at discharge sites. The
drainage ditches will discharge onto the ground by spreading out over the surrounding
vegetation through tapered drains.
8. The Access Roads will be graded to ensure that all runoff is channelled towards the dirty water
drains. A small embankment will be built between the road and clean water drains to prevent
runoff from the road from entering the clean water system.
9. Where possible the natural vegetative barrier will not be disturbed. Protective barriers and
fences will be installed to prevent access to protected areas.
10. All drainage and silt control measures will be regularly inspected during the construction works
to ensure they are performing correctly. When necessary, silt will be cleaned out from silt
control measures and disposed of on site, initially by stockpiling to allow drying out, and then
incorporating into groundwork finishing works.

3.7.1 WATERCOURSE / DRAINAGE CROSSINGS
As part of the upgrade to the existing road and new road construction there will be one drain
and stream surface water drainage crossing. This will include the construction of new drainage
crossings.
The sizing, layout and works methodology of drainage crossings will be agreed with Monaghan
Co. Co. and, where required, with the OPW, prior to construction.
In general drainage crossings will be constructed of concrete precast concrete or High-Density
Polyethylene (HDPE) pipes and will cater for a minimum 1 in 100-year return rainfall event
with an additional 30% allowance for climate change.
• The invert of the pipe will be submerged approximately 1/4 of its diameter below the original
drainage bed. Where natural gradients allow, a nominal back fall in the pipe will be incorporated
to prevent scour and promote the settling of natural material along the invert of the pipe RECEIVED: 07/10/2025

3.8 Proposed Construction Schedule
It is anticipated that the overall construction of the development will take approximately 10 -12
months from starting on-site to final commissioning of the Wind Turbine.
All vegetation clearance that is required for the construction works will be carried outside the
bird breeding season, which runs from the 1st of March to the 31st of August. To comply with
this requirement a section of the initial Civil Engineering Works may be carried out as advance
enabling works in the months from September to February.

3.9 Waste Generated during Construction
The wastes likely to be generated during the construction phase will include the following:
• Excavated material from road cuts and foundations. The material will be stored in a
centralised area to minimise environmental impact and will be used on-site for
hardstanding and embankments;
• Cut-offs from building material. This material will be taken off-site for re-use,
recycling, or taken to a licensed landfill facility;
• Domestic type waste by contractors. This material will be collected on-site, stored in
an enclosed skip and disposed of at a licensed landfill facility
3.10 Material & Disposal of Excavated Material
Where necessary, excavated soil material will be stored, out of the path of trafficking
machinery. Where the topsoil layer must be temporarily held in the spoil storage areas, the
contractor will divide the storage areas to ensure that the topsoil layer is not mixed with the
underlying soils. This will facilitate adequate site reinstatement and ensure re -vegetation of the
land occurs as quickly as possible. RECEIVED: 07/10/2025

DEC Ltd. 24 07/07/2025
Site inspections indicate that the soil conditions at the site will facilitate material being
stockpiled to a height of no greater than 2.0m. Depending on geotechnical considerations, the
maximum gradient of side slopes in the spoil storage areas should be 30-40 degrees to ensure
safe storage of materials and reduce the overall erosion potential at the site. The top of the soil
mound is to be profiled gently to facilitate surface water and therefore prevent ponding and
saturation of the soil. All stockpiling will be temporary and subject to receipt of planning
permission for this application, specific site locations for stockpiling will be determined by the
appointed site engineer and will form part of a Construction Management Plan for the entire
development.
Drainage channels at the uphill side will intercept clean water runoff and will be directed away
from the spoil storage areas to prevent sedimentation. Runoff from the storage areas will pass
through a sediment basin to ensure suspended particles are settled out.
The vegetated top soil layer (300-500mm depth typically) removed from the surface will be
side-cast where feasible and used to resurface ground adjacent to road edges, the turbine base
and other disturbed areas to assist in the recovery vegetation. Re -seeding of the areas will also
be carried out at this stage providing it is the appropriate time of year. Re-instatement will be
carried out as soon as possible after excavation to ensure vegetation recovers without delay.
This will ensure that, as well as restoring the natural environment, the erosion potential for the
soil will be minimised thus reducing the risk of sediment entering watercourses.
The majority of the excavated material (typically clay) underlying the topsoil will be brought
to storage areas. At certain locations along the access road it may be possible to side cast this
material adjacent to the road and place topsoil over it. The to psoil will be graded to reflect the
surrounding landscape. The maximum depth of any side cast material will be 500mm.
In an effort to reduce the storage time of excavated material, a sequential ('rolling') extraction
restoration programme will be employed where feasible i.e. where topsoil and overburden from
one location can be used for the restoration of the previous location.
3.11 Construction Traffic
As with any construction development project, the transport of materials onto the site will give
rise to increased traffic. It is considered that the proximity of the site to the regional route R691, RECEIVED: 07/10/2025

(the primary access road to the site) will reduce the degree of traffic impact that would
otherwise be associated with third class or minor roads.
Public perception of the construction phase will be influenced primarily from the impact of
traffic movements. The degree of traffic disturbance caused by the construction phase of a wind
farm depends on the number of turbines (in this instance a single wind turbine), the associated
civil engineering requirements and the length of the construction period.
The traffic movements to be expected will involve:
• Vehicles bringing concrete (for foundations) to the site;
• Articulated vehicles bringing turbine components to the site;
• Private vehicles of those employed on site for the construction phase; and
• Cranes to erect the turbine.
The largest number of traffic movements will be with the delivery of concrete to the site for
construction of the turbine foundations. In order to assist with logistics for delivery of turbines
the selection of final delivery times and routes will be subject to detailed consultation with the
Planning Authority and the Garda Siochána. The site has good accessibility with close
proximity to a National Road. This will greatly assist the logistics of delivering components on
site, compared to more remote and inaccessible locations.
Once the turbine is in operation, traffic movements to and from the sight will be very light,
probably averaging one visit a week by a light commercial vehicle or car. The potential need
to replace machine components may generate heavier commercial vehicle movements, but
these are likely to be infrequent.
Subject to receipt of planning permission of this application a detailed Traffic Management
Plan will be completed and will form part of the Construction Management Plan.

4.3 Terrestrial Habitats
4.3.1 HABITATS OCCURRING UNDER THE FOOTPRINT OF THE PROPOSED TURBINE
& ASSOCIATED INFRASTRUCTURE
The dominant habitat occurring within the footprint of the proposed turbine location is conifer
plantation with remnant linear sections of cutover/degraded bog occurring along unplanted fire
breaks. The Fossitt Level 3 habitats occurring at the turbine location and along the proposed
access road are outlined in Table 4.1 below. A habitat map showing the extent and distribution
of these habitats is presented as Figure 4.2.

Habitat Description Project Infrastructure
Deposition
Stream –
Legarhill
Stream
The Legarhill Stream is representative of a first order depositing
stream. It is a slow flowing glide stream flowing a path of low
gradient through the project site. The stream displays signs of
enrichment with abundant macrophytes, dominated by Apium
nodiflorum occurring along the channel. Macroinvertebrate
searches identified EPA Class C species, such as Gammurus and
Class C caddis fly species as dominant. Owing to the moderate
water quality status of the stream and the absence of suitable
spawning and nursery habitat, the section of the stream occurring
in the vicinity of the project site is of limited fisheries value.
The proposed access
track will corss the
Legarhill Stream twice
within the wind turbine
site, with one existing
crossing to be used and
one new crossing to be
provided via a piped
culvert.
Improved
agricultural
grassland
(GA1)
Improved agricultural grassland dominates the land cover to the
east of the project along the section of the access track approaching
the substation and surrounding the substation itself. This habitat is
nutrient enriched and intensively managed for cattle grazing and
silage. Species indicative of high nutrient conditions in the habitat
were noted throughout the land holding. These species include an
abundance of Lolium perenne, Holcus lanatus, Alopecurus
pratensis, Ranunculus repens, R. acris, Trifolium repens, Trifolium
pratense, Cirsium arvense, Cirsium vulgare and Urtica dioica.
Stands of Juncus effusus occur within the improved agricultural
grassland sward indicating the peaty and poor drained soils that
underly this habitat.

Habitat Description Project Infrastructure
Overall, the improved agricultural grassland is species-poor and
widespread on a local to national scale. This habitat plays a limited
function in supporting wildlife although it does provide foraging
and dispersal habitat for badgers and can support a lim ited range of
invertebrates.
Recently
felled conifer
plantation
(WS5)
This habitat consists of stand of commercially planted Sitka Spruce
that have been recently felled for harvest. The ground flora within
this habitat is representative of pioneering and ruderal species
commonly associated with recently disturbed ground.
No element of the project
footprint occurs within
this habitat.
Hedgerow
(WL1)
Hedgerows (WL1) occur within the project site and form the
boundary around agricultural fields. Hawthorn (Crataegus
monogyna) is the dominant species. Gorse (Ulex europaeus) and
bramble (Rubus fruticosus agg.) were also present. Occasional Ash
(Fraxinus excelsior) was seen in hedgerows across the site.
Along with Alnus glutinosa, Acer pseudoplatanus, Salix aurita and
Salix cinerea.
Approximately 125m of
hedgerow occurs within
the footprint of the
project.
Buildings and
artificial
surfaces
(BL3)
An existing access track runs through the redline boundary of the
proposed wind turbine site and sections of this are used for the
proposed access track. A former homestead now in ruin is located a
short distance to the southeast of the proposed turbine location.

4.4 Fauna
4.4.1 NON-VOLANT MAMMALS
4.4.1.1 Otters
Otters (Lutra lutra) and their holts and couches are protected under the EU Habitats Directive
as well as under the Wildlife Act (as amended) 1976. Otters holts and couches are generally
established along riverbanks and these mammals are rarely found far away from aquatic
habitats.
The Legarhill Stream was searched for field signs indicating the presence of otters. No field
signs were recorded. The Legarhill Stream is considered to be of limited fisheries value and
this in turn is likely to limit the reliance of otters on this watercourse for foraging.
4.4.1.2 Badgers
Badgers (Meles meles) and their resting place i.e. setts, are protected under the Wildlife Act
1976 (as amended). Setts are generally found in woodland, scrub and along hedgerows in free
draining areas where soil is dry and not subject to flooding. Mire habitats, such as bl anket bog
and heaths, are generally considered to be unsuitable habitat for supporting badger setts due to
the high moisture content associated with peat substrates.
No signs of badgers were found during field surveys within and adjacent to the project site.
4.4.1.3 Irish Hare
The Irish hare is found in many different habitats including unimproved, semi-improved and
improved grassland, upland habitats such as heather-dominated heaths and bogs and in coastal
habitats including sand-dunes. They also tend to occur on modified grassland habitats such as
golf courses and airfields (Fairley, 2001; Dingerkus & Montgomery, 1997). The Irish hare is
protected under Annex IV of the EU Habitats Directive and the Wildlife Act 1976 (as
amended).
No signs of Irish Hare were found during field surveys at and surrounding the project site.

4.4.1.4 Other Mammals
There was no evidence recorded during field surveys suggesting the presence or otherwise of
pine marten or red squirrels (Sciurus vulgaris) and the limited occurrence of woodland habitat
surrounding the proposed development leaves these lands unsuitable for supporting red
squirrels or pine marten.
Other mammals that are likely to occur in the general area include fox (Vulpa vulpa), rabbit
(Oryctolagus cuniculus), hedgehog (Erinaceus europaeus), wood mouse (Apodemus
sylvaticus), brown rat (Rattus norvegicus), and pygmy shrew (Sorex minutus). Foxes are likely
to hunt widely across the surrounding hinterland.
4.4.2 BATS
NBDC & Batlas Records
No records for bats species within the immediate vicinity (i.e. within the area of search as shown
on Figure 2.1) of the proposed wind turbine location are held by the NBDC or the BCI Batlas.
Habitat Classification
A review of the bat landscapes published by Lundy et al. (2011) indicates that the proposed
wind turbine site does not overlap with core areas for bats occurring in Ireland. The habitat
suitability for all bats in the area surrounding the proposed turbine scores a rating of 33.22,
indicating a medium-high sensitivity for bats. The landscape surrounding the proposed wind
turbine site is comprised of open and exposed fields with a well established hedgerow network
occurring at and in the surrounding landscape. High value foraging habitat for bats occur to the
south of the proposed turbine location at Bishops Lough and at Altartate Lough and the
surrounding wetland habitat.
Bat Roost Inspection Survey
The ruined structure to the southeast of the proposed turbine location is of low potential to
support bats. The structure is now comprised of a remain gable wall and stone rubble along
former side walls. Mature cedar and sycamore trees occur surrounding the ruin. These trees did
not support preferred roost features for bats and are considered to be of low roost potential for
bats.

A total of 4,888 bat passes were recorded in the vicinity of the proposed turbine location during
monitoring.
The dominant species recorded during monitoring was Common pipistrelle and Leisler's bat,
followed by Soprano pipistrelle Myotis species were recorded at very low levels during the
monitoring session whilst no activity for Nathusius pipistrelle or brown long-eared bat was
recorded.
There are varying methods to quantity bat activity recorded during automatic static monitoring.
Matthews et al. (2016) provided an arbitrary threshold for levels of low, medium and high bat
activity. Kepel (2011) used the bat passes recorded per hour as a metric against which activity
levels can be assigned. The Mammal Society established EcoBat, an online database that
compares bat activity recorded at a monitoring point against all other bat activity held by the
database for the surrounding area. However the EcoBat application tool is currently unavailable
for use to analyse bat data recorded during automatic monitoring sessions. As such the bat
activity recorded on site has been categorised in line with the method described by Kepel
(2011). Kepel (2011) assigned bat activity based on bat passes per hour as follows: RECEIVED: 07/10/2025

The overall median nightly bat activity levels, as per Kepel (2011) recorded for each taxa during
the monitoring survey are provided in Table 4.3 below. As can be seen on Table 4.3 bat activity
for Common pipistrelle was high, whilst activity for all other species was low.

4.4.3 BIRDS
The project site is not an important area for sensitive bird species (i.e. species listed as Red and
Amber on the Birds of Conservation Concern in Ireland) and has not been identified by
BirdWatch Ireland as being located within a sensitive bird area for wind energy development.
The BirdWatch Ireland Sensitivity Mapping for the surrounding area has identified it to be of
low sensitivity for barn owl (sensitivity score of 14.8).
Bird species recorded during bird surveys completed for the proposed turbine include Buzzard,
Chaffinch, Robin, Wren, Gold crest, Linnet, Chiffchaff, Pied Wagtail, Great Tit, Mute Swan,
Wood Pigeon, Great crested Grebe, Hooded Crow, Jackdaw, Grey Heron, Herring Gull and

No previous records for rare, threatened or protected invertebrates have been recorded at or in
the vicinity of the proposed development. No such invertebrate species were observed during
field surveys.
4.5 Aquatic Fauna
4.5.1 FISH
The water quality of the Legarhill Stream flowing through the project site is perturbed as a
result of excessive nutrient inputs and limits the fisheries value of this river. The River Finn
downstream is similarly affected by nutrient inputs. This river was formerly considered to be
one of the best brown trout fisheries in Ulster, but chronic pollution over years destroyed this
status. Previous IFI fisheries surveys along the River Finn have recorded a total of 9 fish
species. Gudgeon was the most abundant species, followed by roach, brown trout, perch, pike,
European eel, stone loach, three-spined stickleback, and juvenile lamprey.
5.0 SITE EVALUATION

5.2 Habitats
No rare or protected flora species were recorded during the current habitat surveys within or
adjacent to the footprint of the proposed wind turbine site.
The improved agricultural grassland and buildings and artificial surfaces occurring within the
project site are considered to be of low value (Rating E).
The hedgerows occurring within the project site are of local importance (higher value) (Rating

5.3 Fauna
5.3.1 NON-VOLANT MAMMALS
The lands occurring and in surrounding the proposed turbine and development footprint are not
considered to play an important role in supporting significant populations of mammals. No
evidence of non-volant mammals breeding or resting places were identified during field surveys
and no field signs indicating the presence of protected non-volant mammals species were noted
during the surveys. Based upon the findings of the field surveys the site is of low value (Rating
E) for non-volant mammals.
5.3.2 BATS
In line with Kepel’s approach to quantifying bat activity, very low levels of bat activity for all
species was recorded at and in the vicinity of the proposed turbine location.
The presence of Common pipistrelle, Soprano pipistrelle and Leisler's bat foraging at high
levels surrounding the proposed turbine location is not unexpected. These species are
widespread and commonly occurring throughout the country and are “commonly encountered
during bat surveys” (NPWS, 2019). These species are also “very general in their habitat
preference, foraging in woodland, riparian habitats and parkland, along linear features in
farmland, and in towns and cities” (NPWS, 2019). The national population of these three
species is increasing and no existing pressures or threats to the conservation status of this
species at a national level have been identified. Overall the future prospects for this species in
terms of range, population and habitat are ‘Good’ (NPWS, 2019).
In light of the above, the absence of any roosting opportunities within the vicinity of the
proposed turbine location and the high median levels of activity for these species recorded
during monitoring the project site is considered to be representative of a site of local importance
(higher value) (Rating D) for Common pipistrelle, Soprano pipistrelle and Leisler's bat.
5.3.3 AQUATIC FAUNA
The Legarhill Stream is considered to be of limited fisheries value and is of Local importance
(lower value) (Rating E) for aquatic fauna.

6.0 DO NOTHING IMPACT
In the absence of the proposed development the available land-holding and the footprint of the
proposed development will continue to be used for conifer plantation.
7.0 POTENTIAL IMPACTS OF THE DEVELOPMENT
Potential impacts associated with the proposed development will arise during both the
construction and operation phases. The installation of the wind turbine and associated
infrastructure such as hard standing, access road and a grid connection route will result in direct
and permanent habitat loss under the footprint of the development. A further temporary loss of
habitat associated with areas for construction work will arise during the construction phase.
However, with the employment of best practice construction methods, this will be limited and
will be closely associated with the development footprint. Sections 7.1 and 7.2 describe the
impacts associated with habitat loss, severance/fragmentation and disturbance that may arise
during the construction and operation of the proposed development. It is anticipated that direct
impacts associated with the loss of habitats will generally be restricted to the construction phase.
7.1 Construction Phase
The activities associated with the construction phase that will have the potential to affect
habitats and species include:
• The excavation of soils and sub-soils at the turbine-base location and hardstand area
• The upgrade and/or construction of an access road
• The construction of a 20 KV substation
• The construction of a cable duct from the turbine to the substation.
• The operation of heavy plant and machinery
• The management of excavated areas, excavated soil and construction materials stored
onsite.
7.1.1 IMPACTS TO DESIGNATED NATURE CONSERVATION AREAS
The Screening Report for Appropriate Assessment provided with this application examines the
potential impact of the proposed development to European Sites (i.e. SAC and SPAs). No
NHAs or pNHAs are connected to the project and there will be no potential for the project to
result in impacts to such sites in the wider surrounding area.

7.1.3 CONSTRUCTION PHASE IMPACTS TO FAUNA
Potential negative impacts to otters and aquatic fauna of the Legarhill Stream and River Finn
have been considered in Table 7.2 above.
7.1.3.1 Badgers
No breeding sites or resting places of protected terrestrial non-volant mammals such as badgers
were noted within or immediately adjacent to the project site. As such the construction phase
of the project will not have the potential to result in significan t disturbance to non-volant
terrestrial mammals.
7.1.3.2 Bats
The construction phase of the proposed development will not result in the loss of, or disturbance
to any structures with the potential to support roosting bats. No trees with potential to support
roosting bats will be felled as a result of the construction phase.
The proposed wind turbine development will result in the loss of discrete areas of hedgerow
that will be negligible in the context of the mapped area and wider surrounding area of such
habitats. As such the project will not result in a perceptible change to the availability of potential
bat foraging habitat.
Therefore, the potential for negative impacts to bat species as a result of the loss of these
habitats or disturbance during the construction phase is considered to be negligible to minor
and insignificant.
7.1.3.3 Birds
Habitat Loss
The construction phase will result in the loss of minor section of hedgerow that could be used
by birds for nesting. RECEIVED: 07/10/2025

No sensitive species were identified as occurring at or in the vicinity of the project footprint
and the loss of minor area of hedgerow habitat will represent an impact of very low significance
for bird species.
Areas of higher value habitat for birds in the surrounding locality such as at Bishops Lough and
Altartate Lough and the surrounding wetland will not be affected by the project.
In terms of impacts to other passerine species, it is noted that these species are typically short-
lived with high reproduction rates and are not generally considered to be sensitive to
construction effects (Langston et al., 2012). However, the absence of appropriate mitigation
measures and consideration of birds during the breeding season, construction works could result
in disturbance to breeding territories of other bird species that may use scrub habitat within the
footprint of the proposed development. Potential impacts include disturbance to nest and injury
to eggs and chicks and the loss of nesting and foraging habitat.
7.1.3.4 Aquatic Fauna
Earthworks associated with the construction phase of the project will necessitate the denuding
of surfaces. In the absence of appropriate mitigation measures such activities will have the
potential to generate silt-laden runoff from the works area and for this runoff to be discharged
via existing preferential surface water flow pathways and drainage channels crossed by the
project. As part of the project one new crossing of the Legarhill Stream will be required.
During the construction phase standard best practice measures will be implemented on site to
eliminate the loss of contaminated surface water from construction areas to the surrounding
aquatic environment. This in turn will minimise the potential for the project to result in negative
effects to aquatic fauna.

OPERATION PHASE
Refer to the Screening Report for Appropriate Assessment for an examination of potential
impacts to designated nature conservation areas.
7.2.2 OPERATION PHASE IMPACTS TO HABITATS
The operation phase of the proposed development will not cause additional significant or
adverse direct impacts to the quality or functionality of the habitats occurring within the
proposed development area.
7.2.3 OPERATION PHASE IMPACTS TO TERRESTRIAL FAUNA
7.2.3.1 Non-volant Mammals
No effects to protected non-volant mammals are predicted during the operation phase of the
proposed wind farm. As no field signs indicating the presence of such species were noted within
or adjacent to the proposed development footprint during field surveys and due to the limited
human presence for maintenance works during daylight hours, outside the period of peak
badger activity, no significant effects are predicted to affect badgers during the operation of the
proposed wind farm.
7.2.3.2 Bats
Potential effects to the local bat population include the following:
• Effects on bat roosts
• Direct habitat loss
• Displacement and barrier effects
• Fatalities resulting from collision and barotraumas RECEIVED: 07/10/2025

Effects on Bat Roosts
No structures with potential to function as bat roosts occur within 200m of the turbine location.
No trees with potential to support bat roosts occur within a 200m radius of the turbine location.
Due to the absence of a potential roosting opportunities in the vicinity of the proposed turbine
location, there will be no direct or indirect impacts to bat roosts.
Direct Habitat Loss
As outlined in Section 7.1.3.2 the potential for negative impacts to bat species as a result of the
loss of these habitats or disturbance during the construction phase is considered to be negligible
to minor and insignificant.
Displacement & Disruption of Foraging Sites
The potential for displacement of bats from foraging habitats due to their avoidance of wind
turbines is still poorly understood and is likely to result in species-specific behavioural
responses. A number of studies have shown that bats avoid foraging in areas in the immediate
vicinity of turbines (Bach 2002). Other studies have shown that pipistrelle species become
habituated to the presence of turbines and are in general not displaced from foraging habitats
located adjacent to wind turbines (Bach & Rahmael, 2004).
In light of the presence of suitable bat habitat in the wider area surrounding the proposed
turbine, the potential for the turbine to result in displacement/disruption to bat foraging is
predicted to represent an impact of low magnitude and minor significance for the local bat
populations occurring in the wider surrounding area.
Potential Bat Fatalities
Research in Europe, Australia and North America has shown that the operation of wind turbines
can resulted in bat fatalities. The research suggests that peak casualties occur during migration
(Kunz et al. 2007; Rodrigues et al., 2008) and within extensive forested areas (Brinkmann &
Schauer-Weisshahn, 2006). Fatalities at wind farm sites can result from collision with the
turbine and turbine blades and barotraumas (i.e. damage to lungs caused by rapid or excessive
pressure changes in the vortices of moving turbine blades). Baerwald et al. (2008) suggested RECEIVED: 07/10/2025
Client: ART Generation Ltd.
Project Title: Single Wind Turbine, Carney’s Island
Document Title: EcIA
Date: July 2025
Document Issue: Final
SWT Carney’s Island 52 03/09/2025
that barotrauma may be the overriding cause of bat mortality at wind farm sites. More recent
research has questioned this contention with Grodsky et al (2011) concluding that bat fatalities
at wind turbine sites are not exclusively or predominantly a result of barotrauma, but a
combination of both barotrauma and direct collision. More recently the results of forensic
pathology examination of bat corpses at wind farm sites by Rollins et al (2012) goes further in
questioning the predominance of barotrauma at wind farm sites. This research “strongly
suggests that traumatic injury, due to collision, is the major cause of bat mortality at wind farms
and, at best barotrauma is a minor etiology”.
With continued research, the understanding of bat fatalities at wind farm site is evolving. While
it is widely acknowledged that there is a lack of evidence with regard to collision/mortality at
operational wind turbines in Britain and Ireland, it is considered likely that such risks exist due
to the presence of the same species that have been shown to experience fatalities at wind farm
sites in Europe.
In addition to the absence of such evidence, no specific interim guidance is available in Ireland
to support the assessment of wind turbine impacts to bats. Due to the lack of national guidance
this report refers to Scottish Natural Heritage (SNH, 2019), Natural England’s Technical
Information Notes (TIN) 051 and 059 and other recent developments in the research of potential
risks posed by operational wind turbines to bats.
The NE TIN 059 guidance document facilitates an assessment of the potential impacts of a
single wind turbine to bats by identifying:
• The sensitivity of individual bats of different species to mortality based on flight
characteristics and habitat preference etc. and
• The degree of risk to bat populations base on the relative size of the populations of each
species.
The Natural England TINs provide recommendations for avoiding impacts to foraging bats.
This guidance recommends that a 50m buffer should be established between the rotor swept
area of the turbine and the nearest vegetation corridor. The application of a 50m buffer is
considered to minimise potential impacts to bats.

Further risk assessment guidance has also been provided by the Bat Conservation Trust (BCT)
in their guidance document Bat Surveys: Good Practice Guidelines (2012 & 2016). This
guidance sets out a number of factors (see Table 30.1 of the BCT 2012 guidelines) which aim
to establish the potential risk to bat species based on the features associated with a proposed
site and proposed scheme. With reference to both Table 30.1 of the BCT guidelines and the
assessment criteria outlined in the NE TIN 051 Guidelines, the criteria used to establish the
fatality risk posed by the proposed turbine to bat species are as follows:
• Habitat quality surrounding the proposed development
• Presence of bat roosts that may be affected by the proposed development
• Habitat loss and/or displacement;
• Levels of bat activity recorded; and
• Sensitivity of species at the individual and population level to wind turbines
Habitat Quality Surrounding the Proposed Development
High value bat foraging habitat in the form of hedgerow occur in the vicinity of the proposed
turbine location and the wider surrounding area. High value habitat occurs to the south of the
proposed turbine location at lake and wetland habitats. The clearance of this vegetation will not
significantly alter the habitat quality of foraging bats in the surrounding area.
The Natural England guideline for a minimum buffer distance of 50m from the rotor swept area
to the nearest example of structured habitat will be implemented as part of the proposed
development and this buffer will decrease the risk to bat species.
Presence of Bat Roosts that may be Affected by the Proposed Development

High levels of bat activity have been recorded for Common pipistrelle, Soprano pipistrelle and
Leisler's bat at the proposed turbine location.
Sensitivity of Bat Species to Wind Turbines
The sensitivity of each of these species to turbines is outlined in the SNH Guidance document
(2019). Table 7.3 outlines the sensitivity of bats at the individual species level to wind turbines
(Source: SNH, 2019).

Low Risk Medium Risk High Risk
Myotis species Leisler’s bat
Long-eared bats Nathusius pipistrelle
Horseshoe bats Common pipistrelle
Soprano pipistrelle
Pipistrelles
Common, Soprano pipistrelle and Leisler's bat have been classified by the SNH Guidance
document as a species at high risk of turbine collision. Based on the assessment of habitats
occurring in the vicinity of the proposed turbine and the high levels of activity recorded for
Common pipistrelle, Soprano pipistrelle and Leisler's bat at the proposed turbine location, there
is, in the absence of appropriate mitigation measures, for this species to interact with the
proposed turbine. However the implementation of the recommended 50m buffer distance
between the rotor swept area and the nearest structured vegetation will ensure that the
probability of interactions will be reduced to a low risk. A low probability of interaction will
limit the risk of fatality to individual pipistrelles to a low risk level.
Considering the status of these species within the wider geographical context it is unlikely that
the turbine will have the potential to negatively affect these species at a
local/county/regional/national level.

species to vegetated corridors and woodland edge and their low risk classification; the absence
of such habitat features at and immediately surrounding the proposed turbine location; the very
low to near absent levels of Myotis species bat activity recorded during monitoring at the
proposed turbine location; and the absence of lesser horseshoe bats and brown long-eared bat
during monitoring, it is considered that the probability of these species interacting with the
proposed turbine will be low. The implementation of the recommended 50m buffer distance
between the rotor swept area and the nearest vegetated feature will also ensure that the
probability of interactions remains low. A low probability of interaction will limit the risk of
fatality to individual Myotis species and Brown long-eared bats to a low risk level.

7.2.3.3 Birds
Operating wind farms have the potential to affect birds through:
• Reduction in habitat extent as a result of displacement
• Collision with wind turbines
Collision can result in the direct mortality or lethal injury of birds and can result not only from
collisions with wind turbine blades but also with other structures associated within wind
turbines such as towers, nacelles etc. Collision risk can be influenced by topography and
weather, particularly during periods of poor visibility i.e. fog. Other factors influencing
collision risk include species-specific flight behaviour and morphology (de Lucas et al, 2008).
With the exception of notable examples such as Altamont Pass (California), the majority of
studies assessing collision caused by wind farms have recorded relatively low levels of
mortality. However, this may be a reflection of the fact that many wind farms are located away
from large concentrations of birds. Percival (2003) suggested that wind farms in Ireland are
most likely to have serious negative impact to birds where high densities of seabirds, wintering
wildfowl or breeding raptors occur.
The proposed turbine location was not found to be relied upon by target species during baseline
surveys with very low levels of flight activity recorded in the vicinity of the proposed turbine
for those target species recorded i.e. Buzzard, Heron, Herring Gull.
Research (e.g. Vauk, 1990, Phillips 1994, Percival 2000 & 2005, Devereux et al. 2008, Pearce-
Higgins et al. 2012) suggests that most birds are only slightly affected as a result of
displacement by the presence of operational wind turbines. RECEIVED: 07/10/2025

Corvids and passerines represent the most common and abundant group of species occurring
within the vicinity of the proposed turbine. Previous studies have shown that breeding
passerines are not significantly disturbed by turbines. For instance Thomas (199 9) studied the
effects of 10 wind farms in England and Wales on a range of bird species and observed no
significant disturbance to breeding passerines (Thomas, 1999). Ketzenberg et al. (2002) also
showed no effects on number or spatial distribution of skylark within 1km of a wind farm and
noted that some species of waders were more abundant in the vicinity of wind turbines when
compared to pre-installation due to changes in land management. This study also highlights the
potential for habitat quality to outweigh potential negative displacement effects associated with
turbines. Other studies from Spain have shown that passerine numbers are not negatively
affected following wind farm construction (De Lucas et al. 2005) and further evidence comes
from a study of winter farmland birds at two wind farm sites in East Anglia (Devereux et al.
2008). This study looked at four functional groups (seed-eaters, corvids, gamebirds and larks)
and quantified distribution in five 150m distance bands from turbines (0-150m to 600-750m)
as well as examining the closest distance band in more detail to see if there was a difference in
distribution between 0- 75m and 75-150m from turbines. The authors found no evidence to
suggest that the distribution of wintering farmland birds (with the single exception of pheasant)
was affected by wind turbines. Scottish Natural Heritage (SNH) also recognizes the low risk
posed by wind turbines to passerines in the guidance document Bird Survey Methods for
Assessing Impact of Onshore Wind Farms on Birds (2005 & 2014).
The proposed turbine location is situated in an area that is at a remote distance from any
important bird area, the nearest being the Slieve Beagh SPA, located approximately 13km to
the north/northeast of the project site.
Considering the above it is considered likely that the proposed wind turbine will result in a
displacement/disturbance effects of low significant to birds.
Common resident passerines occurring in the landholding area are not considered to be at risk
of collision with the operating wind farm as their flight heights are generally well below the
lowest point of a rotating turbine blade. The risk of collision is assessed as being of negligible
magnitude and negligible significance. RECEIVED: 07/10/2025

The likely grid connection route for the project will connect into the Glencoole 38kV power
station at New Birmingham to the north, northwest of the project site. This grid connection
route will be an overhead cable line comprised of a 20kV electricity cable.
7.2.3.4 Operation Phase Impacts to Aquatic Fauna
Given the separation distance between the proposed turbine hardstand and the Legarhill Stream
the operation phase of the turbine will no pose a risk of contaminated surface water runoff to
the Legarhill Stream.
8.0 MITIGIATION MEASURES
8.1 Construction Phase Mitigation
8.1.1 MITIGATION BY AVOIDANCE
The design of the project has sought to avoid significant negative effects to habitats by
minimising the extent of loss of habitats to the footprint of the proposed development and siting
the infrastructure elements of the proposed development in habitats of low nature conservation
value. The positioning of the turbine to the west of the landholding within an area of industrial
cutover bog has minimised the potential for habitat loss as well as disturbance to adjacent
habitats and fauna occurring in the landholding.
8.1.2 MITIGATION BY REDUCTION
Habitat disturbance during construction work will be confined strictly to within the direct land -
take of the proposed wind turbine and associated infrastructure, in accordance with the outlined
mitigation measures. A project ecologist will be appointed for the construction phase and the
project ecologist will meet with the contractor on site to identify and mark out the required
work area.
The construction footprint will be kept to a minimum and an impermeable barrier will be
installed around the construction area for the turbine base to ensure no surface runoff to surface RECEIVED: 07/10/2025

watercourses. The area of vegetation removal will be kept to a minimum to reduce the exposure
of bare soil and peat and the risk of sediment runoff and peat desiccation.
An approximate 125m of hedgerow habitat will be removed in order to provide for the proposed
turbine hardstand and the access track. An additional 215m of hedgerow habitat will be
removed as part of the bat buffer mitigation measure. The loss of this hedgerow habitat will be
compensated for by providing a broadleaved hedgerow along the length of the access track
from the site entrance to the substation. This will provide for new replacement hedgerow habitat
either side of sections of the access track that will at minimum exceed the 340m plus 100% (i.e.
the provision of a minimum length of 680m of replacement hedgerow habitat. This will result
in a net increase in the extent of this habitat occurring at and in the vicinity of the project site.
It is noted that all new replacement hedgerow will be positioned outside the 50m bat buffer of
the rotor swept area of the turbine.

A minimum 10m construction phase pollution prevention buffer zone (setback) will be applied
to the watercourses that flow through (and adjacent to) the project. This will be applied at all
location except where the proposed access track will cross the Legarhill Stream.
Impositions placed on lands within the buffer zone include no unnecessary construction
activities that have the potential to release pollutants such as re-fuelling activities, plant
maintenance, spoil heaps, materials/fuels/lubricants storage. The following will therefore apply
to the area within the buffer zone:
• No stripping/removal of vegetation;
• No spoil deposition or stockpiling of excavated material; and
• No storage or use of chemicals, fuels, or other lubricants.
Buffer zones described above comply with (or exceed) published guidance for works in
comparable circumstances.
8.1.4 SITE DRAINAGE
Site drainage will be implemented as per the details set out in Section 3.7 above. The
implementation of this drainage design will eliminate the risk of pollution to the Legarhill
Stream and the surrounding surface water environment during the construction phase of the
project.

protection measures will be placed at and downstream of any pumped outlet.
Geotextile silt fences shall be installed adjacent to the live watercourses in order to filter
contaminated runoff that may be caused by plant movement associated with the diversion.
If conditions require, in-channel geotextile check dams will also be installed within the channel

After completion, any temporary scour protection or silt barriers will be removed
8.1.6 CONCRETE, CEMENT & GROUT
Concrete, cement and grout are highly alkaline and corrosive and can have a detrimental impact
on watercourses. To minimise any impact:
• A “record of assessment for low-risk concrete washout discharges” will be completed
to assess the risk to receptors based upon site location and volume of concrete washout
that will be generated;
• Concrete lorries will wash down in designated areas e.g. lined with an impermeable
sheet to prevent ground contamination; and,
• Any concrete or cement mixing will be sited on an impermeable area, at least 10 m
away from a watercourse or surface water drain.
8.1.7 SILT MANAGEMENT
• Water containing silt, or any other contaminating material will not be released directly
to a watercourse or surface water drain. Silty run-off will be routed either overland or
to a suitably designed and sited settlement pond/filter channel. The settlement pond
will be inspected daily;
• Any temporary stockpiling of materials will be prevented from eroding by rainwater or
surface water run-off; and,
• Effluent from wheel washers (if required) and plant washing facilities will be contained
for proper treatment and disposal. RECEIVED: 07/10/2025

8.1.8 DEWATERING / PUMPING AND OVER PUMPING
• Excavations that cannot be drained via gravity will require dewatering and pumping
out of collected rainwater and/or groundwater during construction. All de-watering will
be passed through suitable treatment such as a settlement pond or a mechanical
settlement unit for settling suspended materials.
• Water from excavations will not be pumped directly to watercourses. Where there is a
requirement for over pumping, pumped discharge will be via erosion protection and
over suitable vegetation outside of the buffer zone prior to re-entry to the watercourse.
8.1.9 POLLUTION PREVENTION MEASURES
The primary source of potentially contributing pollution will be from vehicle, plant and
equipment accessing and exiting the site. To prevent pollution of the downstream watercourses
(which flow into the designated Dalgan River section of the Lough Corrib SAC), the following
measures will be employed:
• All work will be carried out in line with GPP 5 “Works and maintenance in or near
water” in order to ensure best practice with regard to the protection of water quality;
• Concrete lorries will wash down in designated areas e.g. lined with an impermeable
sheet to prevent ground contamination;
• Any concrete or cement mixing will be sited on an impermeable area, at least 10 m
away from a watercourse or surface water drain;
• Construction plant will be operated in accordance with the manufacturer’s written
recommendations;
• Vehicle, plant and equipment maintenance records will be kept on site and these will
be made available to the employer’s representative upon request;
• Plant to be refuelled in a designated area, on an impermeable base away from drains or
watercourses;
• Integrally bunded mobile fuel bowsers are to be used;
• Drip trays are to be installed under static plant;

• Liaison with EPA and OPW to take place prior to the commencement of works.
8.1.10 STORAGE OF HAZARDOUS MATERIAL
The Pollution Prevention Guidelines: - GPP26 Safe storage of Drums and Intermediate Bulk
Containers (IBCs) will be complied with on this project. COSHH Risk Assessments will be
completed for all hazardous chemicals brought onto site.
Flammable liquids e.g. petrol, paints and solvents will be stored in secure stores clearly marked
with appropriate warning signs.
Storage for hazardous substances will be as per the suppliers’ recommendations and will be
sited away from sensitive areas of the site. Additionally, the storage area will provide
containment in the event of a spillage.
8.1.11 OIL STORAGE & REFUELLING
Oil is one of the most common pollutants. Spilt oil can pollute streams, rivers and groundwater
supplies which can be used for drinking water.
Types of oil to be potentially found on site include:
• Petrol;
• Diesel;

• Synthetic and mineral oils;
• Biodegradable and;
• Waste oils.
Oil will be stored in dedicated areas in the temporary construction compound. These areas will
be specifically designed and constructed to be safe and secure. All reasonable measures will be
put in place to secure fuel tanks from vandalism.
In all cases, storing oil in high-risk locations such as the following, will be avoided:

• Within 50 m of a spring, well or borehole;
• Within 10 m of a watercourse, ditch or drainage channel; and,
• Where spilt oil could enter open drains or soak into unmade ground where it can pollute
groundwater.
If storing more than 200 litres of oil, a secondary containment system shall be provided. The
capacity of the secondary containment system will be either 110% of the largest drum or 25%
of the total volume stored (whichever is greater). Additionally, all ancillary equipment will be
kept contained within the bund. Any open oil storage areas will be covered in order to prevent
rainwater collecting.
All oil storage areas, containers and secondary containers will be frequently inspected and
checked for signs of damage, corrosion, bulging, leaks or unauthorised use and interference.
Any required maintenance, defects or faults will be repaired immediately.
A designated refuelling area will be established for the project. This area will consist of an
impermeable surface, situated well away from any watercourse. Signage will be erected to
indicate the location of the refuelling area and an oil spill kit will also be at hand at this area.
All fuel deliveries to site will be supervised by a designated individual.
A drip tray, or other secondary containment solution, will be used during refuelling, to prevent
oil from spilling onto the ground. Where mobile fuelling is necessary, all bowsers will carry an
emergency spill kit. All oil containers (including mobile browsers) will be returned to the
designated storage area after use.
A dedicated person will be appointed and trained for the purpose of refuelling on site. An
‘appointed persons poster’ will be completed and displayed on site. The operative will also be
trained in the use of spill kits. In the absence of the primary appointed person for fuelling,
refuelling duties will be delegated to secondary appointed persons. These persons will be
trained in the storage and use of fuel and oils. They will also have been trained in the use of
spill kits. Refuelling must be carried out by a trained operative. RECEIVED: 07/10/2025

8.1.12 SITE COMPOUND
The temporary construction and decommissioning phase site compounds will be installed over
an impermeable barrier. Either existing areas of concrete apron that occur adjacent to the
proposed development footprint will be used or else the foundation of alternative area will be
lined with an impermeable membrane prior to the installation of the site compound. This will
ensure that surface water draining from the site compound is prevented from draining to ground.
Surface water arising from the site compound will be directed to perimeter drains which will
bound the compound. The perimeter drains will be fitted with regularly spaced check dams in
the form of straw bales and/or stone filter dams. The perimeter drain will convey surface water
runoff to a buffered outfall that will discharge waters over peat vegetation. The existing peat
overburden along with the prior treatment along the drains will provide for effective treatment
of the surface water runoff prior to draining to ground.
The site compound will be used to store potentially polluting materials. All potentially polluting
materials such as hydrocarbons, oils and other chemical solutions required for the construction
phase will be stored in a securely bunded containers within a bunded area.
Cement and cement-based products will also be stored in a securely bunded area.
8.1.13 MEASURES TO PREVENT THE SPREAD OF NON-NATIVE INVASIVE PLANT
SPECIES
8.1.13.1 Best Practice & Biosecurity
The following additional measures will be implemented as standard best practice approach to
construction works on site. These measures will be put in place with the aim of avoiding the
introduction of other non-native invasive plant species during the construction and
decommissioning phase of the project. The potential for importation or introduction of non-
native plant species (such as Japanese Knotweed, Himalayan Balsam, etc.) can arise during
construction works on development sites. Section 49 of the European Communities (Birds and RECEIVED: 07/10/2025

Natural Habitats) Regulations 2011 prohibits the introduction and dispersal of invasive alien
species (particularly plant species) listed on Part 1 (third column) of the ‘Third Schedule’.
All construction at the project site will have due regard to the relevant biosecurity measures
outlined below:
• All plant machinery will be restricted from disturbing known colonies of invasive
species.
• All plant machinery will avoid unnecessary crossings to adjoining lands.
Good site hygiene will be employed to prevent the introduction and spread of problematic
invasive alien plant species (i.e. Japanese Knotweed (Lesser Knotweed), Himalayan Balsam
(Impatiens glandulifera), Himalayan Knotweed (Persicaria wallichii), etc.) by thoroughly
inspecting and washing vehicles prior to entering the works area.
The biosecurity measures outlined above are in line with best practice guidelines issued by the
National Roads Authority (NRA, 2010) – The Management of Noxious Weeds and Non-native
Invasive Plant Species on National Roads and broadly based on the Environm ent Agency’s
(2013) – The Knotweed Code of Practice: Managing Japanese Knotweed on Development Sites
(Version 3, amended in 2013, accessed on the Environment Agency’s website on the 11th of
July 2016).
In addition to the above, measures for the prevention and spread of Crayfish plague, as detailed
under SI 354/2018, the European Union (Invasive Alien Species) (Freshwater Crayfish)
Regulations 2018 will be adhered with throughout all construction works and a ctivities. With
regard to such measures the simplest is to implement routine cleaning and drying of equipment
once leaving a river, and before using it again. This is especially important as it is known that
the crayfish plague organism can be carried on wet equipment to new sites. The ‘Check, Clean
and Dry’ protocol is an effective barrier. RECEIVED: 07/10/2025

8.1.14 MITIGATION MEASURES FOR SPOIL DISPOSAL
Spoil will be generated during excavations for foundations at turbines and along new access
roads.
Minimisation of the production of this spoil will be treated as a high priority, but it is nevertheless
expected that peat will be excavated during site works.
Spoil types will be treated separately. Glacial soils and peat will be separated during excavation
and these two types of spoil will be disposed of generally as follows:
A Glacial soils will be deposited directly on top of other glacial soils. This will require the
removal of peat where present to facilitate the process.
B Peat can be disposed of either on top of glacial soils, on top of inactive peat or on top of
the “Acrotelm” where the “Top Mat” has been removed.
1. Glacial spoil disposal will take place within a 100m radius of each structure.
2. It is intended that spoil movements will be minimised by disposing of the material within
or immediately adjacent to the construction footprint of the structure from whence it was
excavated.
3. Preparation of the Spoil Disposal site will involve the removal of the “Top Mat” which
will be transplanted to an area of inactive bog and maintained for re-use during restoration
operations.
4. Spoil will be deposited, in layers of 0.50m and will not exceed a total thickness of 1.50m.
5. Spoil will only be deposited on slopes of < 10 degrees to the horizontal and greater than
10m from the top of a cutting. The exact location of such areas will be determined on
consultation with the geotechnical specialist.
6. A Peat Stability Register will record the location of each Spoil Disposal Site used and
regular weekly assessment will be made by the construction manager or other suitably
qualified individual.
7. Once disposal is complete the disposal sites will be re-vegetated with the “Top Mat” RECEIVED: 07/10/2025

removed at the commencement of disposal operations. Upon commencement of the
restoration phase guidance from a suitably qualified ecologist will be sought to provide a
suitable methodology and programme of maintenance for the restored areas.
8.1.15 BIRDS
The following mitigation measures will be implemented to minimise potential impacts to bird
species:
• Construction activity such as vegetation stripping will be timed to commence prior to
the start of the breeding bird season, which includes the months of March to August
inclusive.
• A Project Ecologist will be appointed for the duration of construction works to advise
the contractor and will visit as necessary when works are in progress to ensure that all
mitigation measures are adhered to. The Project Ecologist will be responsible for
completing pre-construction transect/walkover surveys over the proposed development
site to ensure that disturbance to breeding birds (such as skylarks) is avoided.
• The Project Ecologist will be responsible for undertaking ongoing ornithological
monitoring during periods of the construction phase that overlap with the breeding bird
season. The ornithological monitoring will focus on identifying the presence of
sensitive bird species at the proposed development site. In the event that sensitive bird
species are identified as nesting at or within a 500m buffer zone of the construction
footprint, the timing of works will be scheduled to minimise disturbance to nests and/or
an appropriate buffer distance between the works and any nest site will be implemented.
8.1.16 MITIGATION BY REMEDIATION
When excavating the access road, peat material will be removed and stored separately. This
peat will be stored in designated areas and reinstated along the edges of the completed access
road on completion of construction. The surface of this peat will be seeded with heathland
species such as Calluna vulgaris, Erica tetralix, Myrica gale etc. that are typical of the
surrounding peatland habitats. RECEIVED: 07/10/2025

All spoil material excavated during the construction phase will be reinstated following the
completion of the construction phase of the proposed development. Suitable temporary storage
areas will be identified in advance in association with the site contractors. The Project Ecologist
will review any suggested storage areas for possible ecological interests.
8.2 Operational Phase Mitigation
8.2.1 PROTECTION OF BATS
The Natural England guidance (2014) and NatureScot (2021) recommends that potential
collision to bats from wind turbine developments can be minimised by siting the proposed
turbines so that all parts of the turbine rotor swept area are over 50 m from the nearest vegetated
feature. The location of the proposed turbine will satisfy this recommendation with no vegetated
features occurring within 50 m of a turbine rotor diameter. To this end a “bat buffer” area will
be implemented around turbine such that the buffer area will remain free of suitable foraging
habitat, consisting of conifer plantation edge and scrub. This will require the clearance of
conifer plantation within a 91m radius of the turbine hub.
The implementation of this buffer will increase the total extent of hedgerow clearance to a total
length of 340m.
In order to avoid the potential for future interactions between the now proposed turbine and
local bat populations all structures associated with the project (i.e. the substation building) will
be built in a manner to ensure no roosting opportunities are present to bats. Also, no structured
vegetation will be permitted to establish at these locations during the operational phase of the
turbine.

9.1 Conclusion
The proposed Single Wind Turbine at Carney’s Island is not subject to any statutory nature
conservation designations. The footprint of the project is dominated by habitats of low nature
conservation value. The proposed development site is connected to the Lough Oughter And
Associated Loughs SAC via hydrological pathways. The hydrological pathway will not RECEIVED: 07/10/2025

function as an impact pathway and there will be no risk of likely significant effects to this or
any other European Sites.
A comprehensive approach to the management of surface water drainage will be implemented
from the outset as part of the project. The surface water management measures to be
implemented are representative of best practice construction methods that aim to avoid
contamination of the aquaitc environment. The implementation of such measures will minimise
to an insignificant level the likelihood of any event occurring that could impact on the water
quality of watercourses at and downstream of the proposed site.
A range of mitigation measures have been outlined for the proposed development and with the
implementation of these measures the proposed development will not have the potential to
result in significant negative residual impacts to habitats or fauna occurring at and in the wider
area surrounding the proposed development site.
