Project Location Ballycotton, Co. Cork
Natura Impact
Statement
In cases where an Appropriate Assessment is required a Natura Impact
Statement (NIS) is prepared and includes a report of a scientific examination of
evidence and data, carried out by competent persons to identify and classify any
implications of a project/plan, individually, or in combination with other plans or
projects, for Natura 2000 sites in view of the conservation objectives of the site.
Conclusion
A Natura Impact Statement has been undertaken to determine the significance
of the impact on Natura 2000 sites selected for further assessment in the
screening stage. Provided that the recommended mitigation measures are
implemented in full, it is considered that the project will not affect the integrity
of the Natura 2000 site assessed in this document;

1 INTRODUCTION
1.1 BACKGROUND
The proposal consists of refurbishment and modifications to St. Coleman’s Church of Ireland for
flexible use as a hall including removal of the rear vestry annex and construction of an extension to
provide an entrance/linkage to the adjacent schoolhouse building, and ancillary services to include;
Refurbishment and modifications to former schoolhouse building and change of use from
residential to restaurant
Construction of a store buildings
Construction of open space and car parking area, including playground, picnic and seating
areas, vehicular and pedestrian entrances, pedestrian crossings, site grading, fencing and
rock armour to the northern site boundary (200m length)
Construction of a temporary wastewater treatment plant, surface water drainage and water
utility surfaces
All ancillary site development and landscape works
A Screening for Appropriate Assessment has been completed for the project. The Screening for
Appropriate Assessment was undertaken to determine the potential for likely significant effects of
the project, individually, or in combination with other plans or projects, on Natura 2000 sites in view
of those sites conservation objectives. It has been concluded during the Appropriate Assessment
screening process, that significant impacts on a Natura 2000 site may potentially occur, and could
not be ruled out at stage 1 for one Natura 2000 site; Ballycotton Bay SPA.
Thus a Natura Impact Statement is required to inform the Appropriate Assessment, which will be
carried out by the competent authority. This Natura Impact Statement (NIS) has been undertaken by
Malachy Walsh and Partners ecologists. The test of the assessment is whether the plan or project
will have ‘an adverse effect on the integrity of the site’. Where potentially significant effects are
identified proven mitigation measures will be recommended.
Appropriate Assessment is the consideration of the impact on the integrity of the Natura 2000 site of
the project, either alone or in combination with other plans or projects, with respect to the site’s
structure and function and its conservation objectives. Mitigation of these impacts can be
considered.
2 ASSESSMENT METHODOLOGY
2.1 APPROPRIATE ASSESMENT GUIDANCE
This Natura Impact Statement (NIS) has been undertaken in accordance with the European
Commission Methodological Guidance on the provision of Article 6(3) and 6(4) of the ‘Habitats’
Directive 92/43/EEC (EC, 2001) and the European Commission Guidance ‘Managing Natura 2000
sites’ (EC, 2000) and guidance prepared by the NPWS (DoEHLG, 2009).
2.2 DESK STUDY
In order to complete the NIS certain information on the existing environment was required. A desk
study was carried out to collate available information on the site’s natural environment. This
comprised a review of the following publications, data and datasets:
18902-6004-A Natura Impact Statement June 2018
3
OSI Aerial photography and 1:50000 mapping
National Parks and Wildlife Service (NPWS)
National Biodiversity Data Centre (NBDC) (on-line map-viewer)
BirdWatch Ireland (BWI) on-line data sets
Environmental Protection Agency (EPA) water quality data
Southwestern River Basin District datasets (Water Framework Directive).
Geological Survey Ireland (GSI), area maps
Other information sources and reports footnoted in the course of the report
2.3 FIELD SURVEYS
An ecological site walkover was undertaken on the 16th April 2018 by Malachy Walsh and Partners
ecologist and coastal engineer. Habitats and ecological resources potentially impacted by the
development were identified. Habitats were categorised as per Fossitt (2000). Birds observed and
heard calling were recorded.
2.4 CONSULTATION
The local NPWS representative contacted regarding the proposed development highlighted the
importance of the shoreline and the bay for wintering bird species.
2.4.1 Data request NPWS
A data request was submitted to NPWS for records of any rare or protected flora and/or fauna,
2.4.2 Data request from BWI
The Irish Wetland Bird Survey (I-WeBS) is the scheme that monitors wintering waterbirds in Ireland.
I-WeBS is jointly run by BWI and the NPW. The survey runs from September to March each winter.
Wetlands of all types and sizes are monitored, including estuaries, coastlines, bays, rivers, turloughs,
lakes, streams and flooded fields. I-WeBS involves conducting counts of all waterbirds at wetland
sites once per month from September to March on predefined count days.
A request for IWeBS data was submitted to BWI for the most recent monthly count data of winter
birds available for the Ballycotton Bay SPA.
2.5 ASSESSMENT OF POTENTIALLY SIGNIFICANT EFFECTS
As set out in the NPWS guidance, the task of establishing whether a plan or project is likely to have
an effect on a Natura 2000 site(s) is based on a preliminary impact assessment using available
information and data, including that outlined above, and other available environmental information,
supplemented as necessary by local site information and ecological surveys. This is followed by a
determination of whether there is a risk that the effects identified could be significant. The
precautionary principle approach is required.
Once the potential impacts that may arise from the proposal are identified the significance of these
is assessed through the use of key indicators:
Habitat loss/alteration
Disturbance and/or displacement of species
Water quality and resource
Habitat or species fragmentation
18902-6004-A Natura Impact Statement June 2018

As mentioned, Stage 2 of Appropriate Assessment, otherwise known as Natura Impact Statement,
involves the consideration of the impact on the integrity of the Natura 2000 site of the project,
either alone or in combination with other plans or projects, with respect to the site’s structure and
function and its conservation objectives. Additionally, mitigation of these impacts can be considered.
In cases where an Appropriate Assessment is required a Natura Impact Statement (NIS) shall be
prepared and shall include a report of a scientific examination of evidence and data, carried out by
competent persons to identify and classify any implications for Natura 2000 sites in the view of the
conservation objectives of the site. The aim of the assessment is to provide a sufficient level of
information to the competent authority on which to base their appropriate assessment of the plan
or project. The plan or project should be fully described particularly in relation to the aspects that
could interact with the surrounding environment.
3 DESCRIPTION OF PROJECT
3.1.1 Site Location
The project development site is located adjacent to Ballycotton Bay, Co. Cork, to the north and south
of the R629 as it enters Ballycotton village. It encompasses the St. Colemans Church of England and
adjacent schoolhouse to the south as well as the agricultural fields to the north adjacent to the
shoreline of Ballycotton Bay. Figure 1 shows the site location map. Figure 2 shows the proposed site
boundary.
Figure 1: Site location map
18902-6004-A Natura Impact Statement June 2018

Figure 2: Site boundary
3.1.2 Description of site
The former St Colman’s Church of Ireland is situated at the junction of a local road with the R629
approximately 350m west of the centre of Ballycotton village. The church and the adjacent
schoolhouse and grounds are classified as buildings and artificial surfaces (BL3).
The proposed car parking area to the north of the main road opposite the church comprises two
improved agricultural grassland fields (GA1) delineated by stone walls (BL1) adjacent to the road.
The eastern most field is dominated by winter heliotrope (Petasites fragrans) a garden escape
invasive weed. This parcel of land is narrower than the western section owing to erosion. The length
of the site varies between approximately 45-80 metres north to south with the western parcel
noticeably wider than the eastern.
Rock revetment is proposed for the length of sedimentary cliff (CS3) associated with the proposed
car park (approximately 200m). The adjoining shoreline which is abutted by the sedimentary cliff is a
shingle and gravel shore (LS1) grading into a rocky shoreline. A sea wall (CC1) occurs on the shoreline
to the north east of the proposal site, while rock armour occurs along the shoreline for a length of
approximately 500m to the north-west. The mid to low shoreline is classified as a moderately
exposed rocky shore (LR2) dominated by barnacles Semibalanus balanoides, Chthamalus montagui
and the introduced Austrominius modestus, and seaweeds (Fucus spp.). Periwinkles (Littorina
18902-6004-A Natura Impact Statement June 2018
6
littorea), topshells (Osilinus lineata) and dogwhelks (Nucella lapillus) were abundant with frequent
limpits (Patella spp.). The upper shingle and gravel shore was delineated by a narrow band of
ephemeral green algae (Enteromorpha spp.) while the lower shoreline was dominated by reefs of
honeycomb worm (Saballaria alveolata). Overall species diversity and abundance was low, and there
was a distinct lack of mobile species on all zones of the shoreline.
The development area is underlain by sandstone and mudstone bedrock. The Corine1 landcover
category for the development area is ‘Discontinuous Urban Fabric’ with the surrounding lands to the
west and south categorised as ‘Pasture’ and ‘Arable Lands’.
3.1.3 Purpose of the project
The project forms part of local focused initiatives to promote visitor activities in the area and the
provision of community uses (playground and potential flexible hall use).
3.1.4 Characteristics of the proposal
The project will comprise several elements as described hereunder. Owing to the degree of exposure
of the area, rock armour is required to protect the proposed open space and car park and the
adjacent R629 from erosion. It is proposed to install rock armour for a length of approximately
200m to the northern site boundary.
A surface water drainage system will be established within the carparking area. This will be fitted
with a petrol interceptor and will discharge to the sea north of the site through rock armour which
will attenuate and control the rate of run-off from the site.
A temporary Waste Water Treatment Plant (WWTP) designed to serve a population equivalent of 50
will also be constructed to service the proposed church and restaurant development until the
proposed new Ballycotton WTTP is commissioned. Effluent will be treated to an agreed standard of
20:30:20. The temporary WWTP will connect treated effluent to the municipal network (EPA
Regulation No. D0516-01). Emergency storage will also be provided on the temporary WWTP in
event of a power outage, which will pump to the main sewer.

predominant landuse activity.
4 IDENTIFICATION OF NATURA 2000 SITES
The Screening for Appropriate Assessment was undertaken to determine the potential for likely
significant effects of the project, individually, or in combination with other plans or projects, in view
of the conservation objectives of the site on a Natura 2000 Site. It has been objectively concluded
during the screening process the proposed development, whether individually or in combination
with other plans or projects, beyond reasonable scientific doubt will not have significant effects on
the following European Sites:
Ballymacoda, Clonpriest and Pillmore SAC (000077)
Ballymacoda Bay SPA (004023)
Cork Harbour SPA (004030)
Great Island SAC (001058)
The screening for AA undertaken for this project concluded that significant effects on the
Conservation Objectives of one Natura 2000 site could, potentially, ensue from the proposed
development in Ballycotton. Therefore, further assessment is required to determine whether the
project is likely to adversely affect the integrity of the following Natura 2000 site: Ballycotton Bay
SPA (Site Code: 004022).

4.2 DESCRIPTION OF BALLYCOTTON BAY SPA2 (004022)
Ballycotton Bay is an east-facing coastal complex situated on the south coast of Co. Cork. The
designated site stretches northwards from Ballycotton to Ballynamona, a distance of c.2 km. The site
comprises two sheltered inlets which receive the flows of several small rivers. The southern inlet had
formerly been lagoonal (Ballynamona Lagoon) but breaching of the shingle barrier by erosion has led
to the habitat becoming estuarine in nature since 1991 (Smiddy, 2005). The principal habitat within
the site is intertidal sand and mudflats. The bay has a range of littoral sediments, ranging from the
exposed eastward facing shores of the outer Bay characterised by mobile sands and shingle, to the
mid to low shore and inner bay that supports muddier sediments, with a richer species diversity
(MERC/ERM, 2012).
Saltmarsh and marsh habitat is best represented at Shanagarry and at Ballynamona, while rocky
shore (reef) is exposed at low tide in various locations. Near Ballynamona Lagoon, peat exposures
derived from former lake sediments occur. These exposures have a well-developed gallery of
burrows from a former piddock population but were not found to contain live piddocks (boring
bivalves) when surveyed in 2011. Peat and clay exposures with either existing or historical evidence
of piddock activity are unusual communities of limited extent, adding to the biodiversity interest
where they occur (MERC/ERM, 2012). The relict burrows provide a potential micro-habitat for
species such as small crabs and anemones and the bivalve Ruditapes decussatus is also frequent
(NPWS, 2014). While relatively small in area, Ballycotton Bay supports an excellent diversity of
wintering waterfowl and has nationally important populations of eleven species, of which two,
Golden Plover and Bar-tailed Godwit are listed on Annex I of the E.U. Birds Directive.
4.3 IDENTIFICATION OF POTENTIAL IMPACTS
The following Table 2 lists the SCI’s of the Ballycotton Bay SPA (004022) and evaluates through a
scientific examination of evidence and data whether or not these features should or should not be
selected for further assessment in the NIS. The SCI that are selected for further assessment are
discussed further in the section followed by an assessment of potentially significant effects arising
from the project.

5 ASSESSMENT OF POTENTIALLY SIGNFICANT EFFECTS
This section considers the list of sites identified in section 4 above together with the potential
significant ecological impacts identified in the previous section and determines whether the project
is likely to have significant effects on a Natura 2000 site.
The likelihood of significant effects to a Natura 2000 site from the project was determined based on
a number of indicators including:
Habitat loss/alteration
Water quality and resource
Disturbance and/or displacement of species
Habitat or species fragmentation
The potential likely ecological impacts arising from the project are identified below. The likelihood of
significant cumulative/in-combination effects is assessed in Section 5.5.
5.1 WATER QUALITY AND RESOURCE
Construction phase
The greatest potential sources of water quality impacts during the construction phase of the project
are considered to be excavations to accommodate the open space and car parking area. However,
there are no watercourses within the development site to act as a conduit of potentially polluting
material to the SPA. While deep excavations will be required to facilitate the installation of the car
park to the south and the new surface water drainage system to serve the new hard surface area,
these excavations will be limited in extent within the overall area. The car parking area will be
positioned to the southern end of the existing fields only. The northern section of the site will
remain a ‘green area’ with the existing vegetation being retained along the northern section of the
car parking site, adjacent to the cliff edge/shoreline. These green areas will provide vegetated
buffers which will provide further protection from release of silt/sediment to the bay. Excavations
will not be required to facilitate the placement of rock armour.
The potential exists for accidental fuel and oil spills to reach the SPA through existing groundwater
seepage. The Construction and Environmental Management Plan (CEMP) will make provisions for
fuel management and surface water management during the construction phase of the
development. Section 5.5, below, outlines a programme of mitigation measures designed to control
and eliminate the point and diffuse pollution sources identified and to ameliorate the potential
adverse water quality impacts that might ensue. Water quality protection measures will be
inspected and monitored regularly and records will be maintained of same. The table below gives
the rationale for no significant water quality impacts to the Ballycotton Bay SPA during the
construction phase.

Operation phase
Surface water
Existing surface water at the proposed open space and car parking site percolates to ground. The
current hydrological regime will not be significantly altered as a substantial area of green field to the
north of the car park site will not be developed. The new surface water drainage system will collect
surface water from the newly hardsurfaced areas and will discharge it to the sea through one
discharge point located to the west of the site within the revetment structure. Tarmac will only be
associated with the car parking spaces and the access road within the carpark. The new drainage
system will only serve the tarmac areas of the development area. The surface water drainage system
has been designed to retain the natural drainage regime of the site by maintaining the natural
percolation of surface water through the green field area to the north, while allowing surface water
collected in the new drainage system to percolate through the revetment structure, mimicking the
current natural attenuation and control of surface water from the site. The drainage system will be
fitted with a petrol interceptor.
Foul water
Waste water from the on-site WWTP will not be discharged directly to the sea. Treated foul water
from the new WWTP will be connected to the municipal sewer. Foul water from the site will be
treated to a standard of 20mg/l Biological Oxygen Demand (BOD) and 30mg/l Total Suspended Solids
(TSS) and 30mg/l Ammonia. The WWTP is designed to serve a p.e. of 50, with emergency storage
provided to pump to the main sewer in the event of a power outage. Significant water quality
impacts owing to the proposed on-site WWTP are not envisaged. As a precaution, mitigation
measures are included in 6 below.
18902-6004 Natura Impact Statement June 2018
17
Conclusion
With the appropriate mitigations in place, the physicochemical properties of the receiving
environment will not be significantly impacted by the proposed discharges, thus prey habitat and
abundance is not envisaged to be significantly impacted. It is concluded that significant water
quality impacts to the Ballycotton Bay SPA during either the construction or operational phases of
the proposal are not likely to occur as a result of the proposed works.
5.2 HABITAT LOSS/ALTERATION
Construction Phase
The Ballycotton Bay SPA is of special conservation interest for a number of intertidal wetland bird
species (See Table 2 above). The principal habitat within the site is intertidal sand and mudflats.
These are mostly well exposed and the sediments are predominantly firm sands. In the more
sheltered conditions of the inlets, sediments contain a higher silt fraction. The intertidal flats provide
the main feeding habitat for the wintering birds. Sandy beaches are well represented. Salt marshes
fringe the flats in the sheltered inlets and these provide high tides roosts. A small area of shallow
marine water is also included3.
The principal wetlands within the SPA are of Conservation Interest of the Ballycotton SPA site, as a
foraging resource for the SCI bird species of the Ballycotton Bay SPA.. The Conservation Objectives
for wetlands within this SPA are to maintain the favourable conservation condition of the wetland
habitat in Ballycotton Bay SPA as a resource for the regularly occurring migratory birds that utilise it.

The rock revetment will be confined to the upper shoreline immediately adjacent to the sedimentary
sea cliff, for a length of 200m east to west, which is located above the high water mark of the
shoreline. An existing band of ephemeral shingle and gravel occurs adjacent to the sea cliff at this
location. This habitat is not considered as important a food resource to birds as the rocky shoreline
3 https://www.npws.ie/sites/default/files/protected-sites/synopsis/SY004022.pdf
18902-6004 Natura Impact Statement June 2018
18
that extends from the mid shore to the lower shore. The rock revetment will be placed along the cliff
for a total length of 200m and will extend approximately 15m from the sea cliff. Rock revetment will
not encroach into the rocky reef habitat that dominates the shoreline in this location. There will be
no direct impacts to the principal wetland habitats listed above, as a result of the proposed
development. Principal wetland habitats associated with the SPA, namely, sand flats, mud flats and
salt marshes are located to the north west of the site approximately 740m from the site location.
There will be no direct impacts to these habitats during the construction phase of the development.
The preceding section 5.1 concluded that significant water quality impacts during the construction
phase were not expected with the appropriate mitigations in place, therefore habitat loss or
alteration through water quality impairment is not reasonably foreseeable.
Operation phase
The principal wetland habitats located north west of the proposal site have potential to be indirectly
altered or lost through changes in coastal processes owing to the placement of rock revetment. Rock
revetment has potential to alter the sediment transport regime of the bay thereby altering the
supply of sediments to these habitats. There will be no disruption or alteration to the natural coastal
processes of the Ballycotton Bay owing the proposed development; in particular the placement of
rock revetment will not alter the sediment transport regime of the Ballycotton Bay. Refer to
Appendix 1 for the Ballycotton Coastal Process Study. Models were run to simulate the wave
climate, the tidal current and sediment transport regime to determine the movement of sediment
along the beach. Coastal process modelling shows that the primary driver of erosive sediment
transport is wave action which approaches the shoreline directly and so results in cross shore
movement of sediment. These models showed that there is very little tidal driven movement of
sediment outside the immediate flow path of the estuary, located approximately 740 m north west
of the site and since the new revetment works are outside the active transport zone they are not
likely to have any impact beyond their immediate location.
The preceding section 5.1 concluded that significant water quality impacts during the operation
phase were not expected with the appropriate mitigations in place, therefore habitat loss or
alteration through water quality impairment is not reasonably foreseeable.
Conclusion
With the appropriate mitigations in place, it is concluded that significant habitat loss or alteration
impacts to the Ballycotton Bay SPA during either the construction or operational phases of the
proposal are not likely to occur as a result of the proposed works.
5.3 DISTURBANCE/DISPLACEMENT OF SPECIES
Prey availability for SCI species within the receiving waterbody and shoreline will not be altered as
the preceding sections 5.1 and 5.2 concluded that the water quality and habitat availability and thus
the prey community within the receiving environment will not be significantly impacted as a result of
the project. As shown in Table 4, the majority of SCI species feed in the intertidal flats. Table 9 below
lists the preferred trophic guild and prey requirement for the SCI species of the Ballycotton Bay SPA.

As discussed in the preceding sections 5.1 and 5.2, the water quality of the receiving environment will not be significantly impacted by the proposed discharges,
thus prey habitat and abundance is not envisaged to be significantly impacted.
Construction phase
Since the SCI species listed in the Conservation Objectives of the Ballycotton SPA are non breeding populations, impacts on their breeding are not expected.
The proposed construction works to facilitate development will be conducted at the eastern extremity of the Ballycotton SPA. There is the potential for some very
localised and temporary disturbance and/or displacement of SCI bird species potentially foraging in the area. A certain amount of activity already exists in the
area, including the village/dwellings to the east and south, vehicular/traffic associated with the main Ballycotton road, and agricultural activities in the area
(agricultural grassland/silage harvesting/arable land etc). The scale of the proposed works, the level of activity currently in the area, in addition to the fact that the
proposed works are situated at the eastern extremity of this SPA site outside the principal wetland habitats, indicates that any potential disturbance/displacement
impacts during the construction phase will be localised and temporary in nature.

19033-6004 Natura Impact Statement June 2018
20
Operation phase
After the construction phase, all foraging bird species are expected to utilise the shore habitats
adjacent to eh development area. The green field area that will be maintained tot eh north of the
open space and car parking area will buffer the potential noise and visual disturbance emanating
from the site. Birds are expected to become habituated to the increased levels of activity within a
short period of time. The change of use of the existing grassland fields to car park and open space is
not expected to have a significant impact on wintering birds within the SPA as the site is considered
sub-optimal for roosting SCI species. In the event that the site is used by either foraging or roosting
species, the change of use is not expected to have a significant impact on SCI’s as there is an
abundance of similar and higher value habitat in the overall area. Furthermore, in the absence of
coastal protection the fields/cliff are expected to be lost to erosion in a number of years. Therefore
the habitat will be unavailable to foraging and roosting birds. Owing to the proximity to the local
road and passing traffic It is expected that the SCI’s of the Ballycotton SPA choose higher value
foraging and roosting habitat located within the principal wetland habitats of the SPA site. . The SCI’s
of the Ballycotton SPA that rely on the principal wetland habitats extending away from the
development site to the north west, are not expected to exclusively rely on the existing sub optimal
habitats at or adjacent to development site.
Conclusion
It is therefore concluded that significant disturbance/displacement impacts to the SCI habitat or
species of the Ballycotton Bay SPA during either the construction or operational phases of the
development are not likely to occur as a result of the proposed works.
5.4 HABITAT OR SPECIES FRAGMENTATION
Given the nature and location of the works, and due to the fact that the proposed development is
situated towards the eastern extent of the Ballycotton SPA, habitat or species fragmentation is not
envisaged as a result of either the construction or operational phases of the proposal. Therefore,
significant habitat or species fragmentation impacts are not likely to occur.
The preceding sections have concluded that significant habitat loss or alteration impacts to the
Ballycotton SPA are not likely, with mitigations in place, no significant water quality impacts are
predicted and significant disturbance or displacement to any species are not expected to ensue.
Having regard to the location, existing activities at the site, nature and scale of the proposed works,
and the conclusions of the preceding sections, it is considered that significant habitat or species
fragmentation impacts are not reasonably foreseeable as a result of the proposal.
5.5 ASSESSMENT OF POTENTIALLY SIGNIFICANT CUMULATIVE EFFECTS
As well as singular effects, the potential for in-combination or cumulative affects also need to be
considered. A cumulative impact arises from incremental changes caused by another past, present
or reasonably foreseeable future actions together with the proposed developments. The EC (2001)
guidelines on the provision of Article 6 of the Habitats’ Directive state that the phrase ‘in
combination with other plans or projects’ in Article 3(3) of the Habitats Directive refers to the
cumulative impacts due to plans or projects ‘that are currently under consideration together with
the effects of any existing or proposed projects or plans.’ Relevant plans and projects have been
identified in Section 3.1.5, above. There is the potential for significant ecological impacts at large
distances from the proposed development. A distance of 15km from the subject site has been
considered in this assessment of cumulative impacts.
18902-6004 Natura Impact Statement June 2018
21
5.5.1 Plans
The proposal was considered in combination with other plans and projects in the area that could
result in cumulative impacts on the Ballycotton SPA. Other plans considered include:
Cork County Development Plan 2014
Cork County Local Area Plans- East Cork Municipal District
No significant cumulative impacts are predicted with the plans listed above, as each plan has a range
of environmental and natural heritage policy safeguards in place. These safeguards to protect the
natural environment and Natura 2000 Sites will also apply to the proposal described in this report.
The assessments completed in the preceding subsections have concluded that no significant direct
or indirect impacts on the Ballycotton Bay SPA are expected to ensue from the proposed project.
Development within the SPA will be confined to the 200m stretch of sea cliff associated with the
development site that is currently affected by coastal erosion along the coastline.
The main impacts that could ensue on the SCI species comprise those that could result from
potential impacts to water quality. A search for relevant plans and projects completed in section
3.1.5 above, determined that there are no current planning applications or grants of permission for
any large scale projects or plans in the area adjacent to the proposed development.
The main threats to water quality in the area, are on-going agricultural and recreational landuses
and domestic wastes. The temporary on-site WWTP is proposed to serve the development as the
Ballycotton WWTP does not currently have the capacity to do so. The main potential cumulative
water quality impact would be in terms of a potential increase in nutrient levels in the principal
wetland habitats within the Ballycotton SPA. There is limited potential for the proposed
development to contribute to a cumulative impact on water quality in the Ballycotton Bay SPA.
Effluent will be treated to a 20:30:20 secondary standard. Upgrading works at the Ballycotton WWTP
are expected to be complete by 2021, by which time the on-site WWTP will be decommissioned and
the development area will be connected directly to the municipal network.
It is considered that in the presence of mitigation that no significant cumulative impacts to water
quality within the Ballycotton Bay SPA will arise as a result of the construction/operational phases of
the proposed development.
It is concluded therefore, bearing in mind the scope, scale, nature and size of the development and
having regard to the mitigation measures outlined in Section 6 below, that significant cumulative or
in-combination impacts to the Ballycotton Bay SPA are not reasonably foreseeable.
18902-6004 Natura Impact Statement June 2018

6 MITIGATION
6.1 SEASONAL TIMING OF THE WORKS
In order to avoid impacts on the populations of wintering bird species for which the Ballycotton Bay
is designated the placement of rock armour will take place outside the months of peak wintering
bird activity. Advice on suitable timing of coastal works shall be sought from NPWS prior to
placement of rock revetment.
6.2 CONSTRUCTION AND ENVIRONMENTAL MANAGEMENT PLAN (CEMP)
The final CEMP will be implemented by the appointed contractor and will manage the environmental
commitments of the project. The implementation of proposed mitigation measures, as well as the
monitoring and supervision of these measures will be managed through the CEMP. Mitigation
measures to prevent significant negative impacts on the Conservation Objectives of the BAllycotton
Bay SPA will be incorporated into the project through the CEMP. The finalised CEMP will take
cognisance of CIRIA technical guidance on water pollution control (Murnane, E., Heap, A., and Swain,
A., 2006) and will include the following:
Noise, Vibration, Dust and Air Control
Management of Construction and Demolition Waste
Water Quality/Sediment and Erosion Control
Fuel and Oils Management
Management of Concrete
Emergency Response Plan
Site Clearance Plan
Construction method statements will be prepared prior to commencement of construction
and incorporated into the CEMP.
6.3 WATERCOURSES (GENERAL MEASURES)
The main risk to the water quality results from the potential for ingress of sediment or accidental
fuel or oil spillages discharging to watercourses during construction. Sediments can be released
during excavation and construction works. The following measures will be incorporated so as to
ensure no significant negative water quality impacts occur. These measures will be incorporated into
the finalised CEMP;
Raw or uncured waste concrete / cementitious material will be disposed of by removal from
the development area;
Suitable excavated soil will be re-used as backfill and landscaping. Temporary stockpiles will
not be permitted along the cliff edge. Silt fences will be installed on the seaward side of
temporary stockpiles to prevent run-off in the event of an adverse weather event;
The site compound will be situated at least 25m from the cliff edge;
Fuelling and lubrication of equipment will be carried out under controlled conditions in
bunded areas within the site compound and away from the cliff edge;
Any spillage of fuels, lubricants or hydraulic oils will be immediately contained and the
contaminated soil removed from the site and properly disposed of;
Sufficient oil booms and oil soakage pads will be kept on site to deal with any accidental
spillage;
18902-6004 Natura Impact Statement June 2018
23
Waste oils and hydraulic fluids will be collected in leak-proof containers and removed from
the site for disposal or re-cycling;
Prior to any work it will be ensured that all construction equipment is mechanically sound to
avoid leaks of oil, fuel, hydraulic fluids and grease; and
Overnight parking of plant machinery and site vehicles will only take place in the designated
site compound area away from the cliff edge.
6.3.1 Runoff and sediment control
Measures to ensure erosion control, where runoff is prevented from flowing across exposed ground,
and sediment control, where runoff is slowed in order to allow suspended sediment to settle, will be
implemented into the finalised CEMP to prevent transport of sediment to the Ballycotton Bay should
any unforeseen delays or unexpected weather events occur. These measures will include the
following:
Existing vegetation within the proposed green areas to the south of the open space/car park
will be retained. Exclusion zones will be set up around these green areas. Vegetation will not
be removed.
Implement control measures to prevent runoff flowing across exposed ground within the
working areas and become polluted by sediments;
Regularly inspect and maintain surface water and sediment controls. Inspection and
maintenance is especially important after prolonged or intense rainfall;
Additional protection by silt trapping apparatus such as a geotextile silt fence to prevent
contaminated runoff;
Temporary silt fences should be erected to trap sediment particles when work is taking place
during a prolonged wet weather period or intense rainfall event;
6.3.2 Concrete
It is important to prevent concrete/tarmacadam from entering the Ballycotton Bay. The following
measures will be implemented during construction of the development:
Washout of concrete trucks will not occur within the development area. Trucks will return to
the supplier’s yard for wash out;
A designated trained operator, experienced in working with concrete will be employed
during any concrete pouring ;
Any small volumes of incidental wash generated from cleaning hand tools, cement mixers or
other plant, as required, will be trapped on-site to allow sediment to settle out and reach
neutral pH before clarified water is released to the surface water drains or allowed to
percolate into the ground. Settled solids will need to be appropriately disposed of off‐site.
The total volume will be reduced by only permitting concrete chutes to be washed on site.
6.3.3 Fuel and Oil Management Plan
Fuel oils must not, under any circumstances, discharge into the aquatic zone. The fuel and oil
management plan outlined in this statement will be incorporated into the conduct of the works.
These measures to prevent fuel and oil from entering any surface water body and will describe the
emergency procedures designed to control any accidental spillages. All site plant and machinery e.g.
excavators, dumpers etc, will be refuelled in a, bunded, designated area at least 50m from any water
body. No servicing or repair of plant, machinery or vehicles will be undertaken outside the site
compound area. The management of fuel on site will have regard to the following elements:
18902-6004 Natura Impact Statement June 2018
24
Machinery will be confirmed as being mechanically sound and without fuel or oil leaks and
fit for purpose prior to project start
To minimise the requirement for refuelling during operations, plant will be refuelled prior to
the start of each day’s works program
Fuelling and lubrication of equipment will be carried out in bunded areas
Use of biodegradable products where possible, e.g. hydraulic fluid
Mobile bowsers, tanks and drums will be stored in secure, impermeable storage area within
the site compound
Fuel containers must be stored within a secondary containment system e.g. bund for static
tanks or a drip tray for mobile stores
Ancillary equipment such as hoses, pipes must be contained within the bund
Taps, nozzles or valves must be fitted with a lock system
Fuel and oil stores including tanks and drums will be regularly inspected for leaks and signs
of damage
Only designated trained operators will be authorised to refuel plant on site and emergency
spill kits will be present at equipment for all refuelling events
Procedures and contingency plans will be set up to deal with an emergency accidents or
spills
An emergency spill kit with oil boom, absorbers etc. will be kept on site in the event of an
accidental spill
Fuels, lubricants and hydraulic fluids for equipment used will be carefully handled to avoid
spillage, properly secured against unauthorised access or vandalism and provided with spill
containment according to current best practice
Procedures and contingency plans will be set up to deal with emergency accidents or spills
6.3.4 Plant management
Plant and machinery management measures shall be implemented to ensure that plant
machinery is appropriately managed for the duration of the progamme of works. Operators
shall adhere to the following practices:
Vehicle and equipment operators must have appropriate training and qualifications for
proper and safe use of their equipment
Operation of all vehicles, vessels and equipment will be carried out in a safe and professional
manner
The fuel management plan as outlined at XXXXwill be adhered to at all times
To avoid risk of spills or leakages into the marine environment continuous care and
maintenance of vehicles and equipment will be maintained
All filters, oils, lubricants and other related materials will be disposed of properly
Plant will be parked in the secure compound when not in use
6.4 EMERGENCY PLANS AND PROCEDURES
The contractor will prepare an emergency response plan and set of procedures for incidents/events
likely to cause pollution including the pollution of Ballycotton Bay with silt/sediment, fuels/oils, etc.
The contingency plan in place during construction and displayed at appropriate locations.

6.5 CONSTRUCTION OF COASTAL PROTECTION ROCK REVETMENT
Coastal protection works will be restricted to the area above the mean high water mark.
Temporary access to the shoreline will be clearly demarcated for vehicles and personnel.
Exclusion zones will prevent access to the rocky habitats within the mid and low shore.
Natural re-vegetation of the cliff top from the existing seed bank will be facilitated.
6.6 DISTURBANCE TO FAUNA (GENERAL MEASURES)
Habitat disturbance to fauna will be limited by controlling the movement of vehicles and
personnel. Construction vehicles and personnel will not encroach onto habitats beyond the
proposed development footprint. Exclusion zones will be established on the shoreline to
protect the reef habitats that extend from the mid shore to the low shore. Vehicles and
personnel accessing the shoreline during construction of rock armour will follow a
designated route along and within the upper 15m of shoreline. Vehicles, plant and personnel
will not be permitted outside this 15m exclusion zone.
To reduce the level of disturbance to fauna, construction activities will be restricted to
between 7.30am and 7.30pm, Monday to Friday and between 8am and 6pm on Saturdays.
Construction work will not take place outside of these hours unless in exceptional
circumstances.
6.7 INVASIVE SPECIES MANAGEMENT
To reduce the likelihood of invasive species being introduced to the site from construction works on
other sites, it will be required that vehicles and tools will arrive on site already steam washed. Work
boots will be dipped in or scrubbed with a disinfectant solution and thoroughly dried afterwards
before being used on the site for the first time. All PPE will be visually inspected and any attached
vegetation or debris removed. PPE and tools will remain on site for the duration of construction.
Any machinery or equipment returning from a different construction site will cleaned, steam washed
and visually inspected again before re-entering the site.
To reduce the likelihood of invasive species being introduced to the site from quarries, the
aggregate will be crushed stone which will be biologically inert and would not be expected
to have a seed bank.
To reduce the likelihood of invasive species spreading throughout the site, the construction
personnel involved in works will be trained in basic relevant invasive species prevention and
management.
Invasive species management methodologies and plans outlining Best Available Techniques
(BAT) will be sourced from current best practice/TII (The Management of Noxious Weeds
and Non-Native Invasive Plant Species on National Roads).
6.8 MAINTENANCE OF WWTP AND SURFACE WATER DRAINAGE
In order to prevent water quality impairment in the Ballycotton Bay SPA/wetland habitats during
operation, the following shall be undertaken:
Regular maintenance of the on-site WWTP shall be undertaken;
The WWTP will be serviced by a licensed operator;
Silt traps will be included on the new surface water drainage system;
Petrol interceptor will meet a minimum requirement of Class 1 “by-pass” separator with
trigger alarm (UK Environmental Agency PPG3, 2006).
18902-6004 Natura Impact Statement June 2018

7 RESIDUAL IMPACTS
Residual impacts are impacts that remain, once mitigation has been implemented or, impacts that
cannot be mitigated.
Provided all mitigation measures are implemented in full and remain effective throughout the
construction phase/operational phase, no significant residual impacts on the Ballycotton Bay SPA are
expected from the proposed development.
Conclusion
It is objectively concluded, provided the recommended mitigation measures are implemented in full,
that the impacts identified in Section 4.3 above, will not result in adverse effects on the integrity of
the Ballycotton Bay SPA (Site Code: 004022), either as a standalone project, or in combination with
other project/plans.
