1. Introduction
Atkins have been commissioned by Transport Infrastructure Ireland (TII) to install a concrete invert at Knockakip Culvert (KY-N21-016.00), Co. Kerry. The scope of this Natura Impact Statement (NIS) is for the proposed project at Knockakip Culvert. The proposed project falls under the TII Munster Bridges Term Maintenance Contract No. 3. 1.1. Project Context
The EIRSPAN Bridge Management System covers all aspects of bridge management including routine maintenance. Over the past number of years TII have undertaken routine bridge maintenance contracts under Bridge Term Maintenance Contracts. A TII Bridges Term Maintenance Contract is currently being delivered for all National Road Bridges in Munster.
Under the Munster Bridges Term Maintenance Contract No. 3, Atkins has been appointed as the Consultant to carry out services under the Contract such as bridge inspections and reporting, ecological assessment, production of contract documents, tender assessment, contract administration and site supervision. The Contract involves the annual inspection and undertaking of routine and reactive maintenance works to all National Road Bridges across all counties in the Munster region, namely counties Cork (City & County), Kerry, Waterford, Tipperary, Limerick and Clare. This contract will run until 2021, where it is intended to carry out annual routine maintenance work between circa June and December in each year. All works from each year will be subject to the Appropriate Assessment (AA) process.
It is proposed to install concrete inverts to all existing corrugated steel culverts under National Roads in Munster. These culverts were installed during the 1970s and 80s. The culverts now show signs of significant corrosion and to maintain their structural integrity, a concrete invert liner is to be installed. Under the current Bridges Routine Term Maintenance Contract TII have selected 5 corrugated steel culverts for concrete invert lining. These culverts are presented in Table 1-1 below.
The culverts proposed for concrete invert installation initially underwent Screening for Appropriate Assessment in 2018. TII determined that likely significant effects to European sites, in view of their conservation objectives, could not be ruled out and thus required Appropriate Assessment. Thus, the proposed concrete invert installation at Knockakip Culvert requires further assessment.
For the purposes of assessment, the 5 culverts in Munster have been grouped according to their potential zone of influence and location within Water Framework Directive (WFD) catchments. Using this system, 3 groups were established. These groups are detailed in Table 1-1. Where European sites are located within the potential zone of influence of more than one grouping, the potential for cumulative impacts shall also be considered. Knockakip Culvert is assigned to Group 1, which is in the Tralee Bay - Feale WFD catchment.

1.2. Project Description
Transport Infrastructure Ireland undertake routine bridges maintenance works to structures associated with the National Roads Network. This project comprises the provision of a concrete invert lining and associated instream works to Knockakip Culvert (KY-N21-016.00), Co. Kerry. Knockakip Culvert is located on the N21, approximately 6km north-east of Castleisland town. Knockakip Culvert is situated on the Ballyduff stream, which is a tributary of the River Owveg, located in the Feale subcatchment.
This corrugated steel structure has been identified as having durability and structural issues as a result of the erosion of previous bitumen protection linings and progressive corrosion of the metal particularly in the lower region. The purpose of the concrete invert is to mitigate further corrosion and section loss to the invert of the culvert and to restore and maintain it structural integrity.
It should be noted that the scope of the proposed project is the replacement of the existing concrete lining at the base of the culvert. Given engineering constraints for the structure, it is not feasible to retrofit a ledge for mammal passage within the existing structure. The design and installation of an entirely new structure would be required for this to be achieved, which is outside the scope of the proposed project.
The culvert will be dammed upstream and downstream within 10m of the culvert using double lined sand bags, filled with clean sand, tied and wrapped in heavy gauge polyethene.
There will be three dams erected in the stream; dam 1 upstream of the culvert and dam 2 &3 situated downstream of the culvert (Figure 1-1). Dam 2 and 3 will be erected first, 300mm high on the stream bed. Dam 1 will then be erected, and the stream flow pumped downstream of dam 3. The intake will be fitted with a filter to ensure no fish enter the pipeline. The outfall pipeline will be fitted with a silt sock. This will dissipate flow and prevent scour of the river bed. The stream between dam 1 & 2 will be electro fished and the fish placed in the pool created between dam 2 and 3. On completion of the electro fishing dam 2 will be raised to full height and a silt fence will be erected between dam 2 and dam 3 and a second silt fence will be erected just upstream of dam 3. The water between dam 1 and dam 2 will be pumped into the pooled area between dam 2 and dam 3 in advance of the silt fences. A shallow sump will be excavated (or naturally occurring) in the stream bed upstream of dam 2 to catch surface water and cleaning water from power washing the culvert. The collected water in the sump will be pumped downstream between dam 2 and dam 3 and discharge in advance of the silt fences.
Large boulders will be removed from the riverbed prior to placing a heavy-duty geotextile on the river substrate and stored within the works area for reinstatement on completion of the works. A hardstanding working platform will be placed over the geotextile upstream and downstream of the culvert. The working platform will consist of clean gravel/ crushed rock (typically 250mm thick depending on the riverbed ground conditions). Existing stream bed material within the metal culvert will be captured and stored within the works area for reinstatement on completion of the concrete lining. The corrugated steel culvert will be cleaned by power washing and hand-held mechanical tools such as wire brushing and grinding. The power washing water will be collected in a sump within the works area (i.e. upstream of dam 2) and discharged through the double silt fencing and dam 3 before entering the downstream waters. Arisings from the corrugated metal culvert cleaning will be collected within the culvert and disposed off-site to a licensed waste facility. Prior to placement of the lining, the corrugated steel culvert invert area to be lined will be primed with anti-corrosion primer, prior to placing 150mm thick (nominal) reinforced (stainless steel) concrete to circa one-third of the culvert height. On completion of the culvert lining works the temporary working platform and geotextile will be removed. The culvert bed will be reinstated with stream bed material that was removed from the culvert prior to the works and the stream bed will be regraded locally to the culvert ends with clean natural gravels to realign the culvert and stream bed levels.
The drawing detail of the proposed works is included in Appendix A.
The Contractor’s method statement details how the works will be carried out and the works sequence. The Contractor’s method statement is included in Appendix B and is summarised in the text below along with general specifications of the works from the contract’s Works Requirements Specifications.

1.2.1. Working Methods
Under the Munster Bridges Term Maintenance Contract No. 3, the works are carried out according to the Works Requirements Specifications. This details the general specifications of the works, which includes the installation of concrete inverts to corrugated structures: -
“The contractor shall remove all silt/debris and deposit build-ups from the structure ensuring appropriate downstream silt containment measures are in place. The existing invert shall be prepared for the installation of the sprayed concrete invert (HTR-DR 1006 & 1007) by cleaning back to bright steel. Removal of all detrimental contamination and corrosion products using handheld tools to produce a generally bright appearance overall. The surfaces shall be free of embedded abrasive particles and corrosion products when viewed through a x10 illuminated magnifying glass. The invert shall then be coated with the corrosion inhibitor Galvafroid manufactured by Fosroc. An anti-corrosion steel primer, Nitoprime Zincrich Plus by Fosroc, will be used to prime the steel”.
Fosroc were contacted regarding the above products proposed to be used during the installation of the concrete invert, as the Safety Data Sheets (SDS) for Galvafroid and Nitoprime Zincrich Plus categorise these products as ‘Aquatic Acute (1-H400) and Aquatic Chronic (1-H410)’. The SDS states that the products ‘contain a substance which is toxic to aquatic organisms and which may cause long-term adverse effects in the aquatic environment’. Fosroc confirmed that the danger to aquatic organisms arises from chlorinated paraffin, which is used as a plasticiser for the product when in a liquid state. These products will be applied during the installation of the concrete culvert in a dry working area. Once cured this material is bound in a polystyrene matrix and no longer mobile. Therefore, it is not regarded as a pollutant in its cured and solid state. These products are not epoxide resin-based coatings, which have been shown to potentially have adverse effects on the aquatic environment (Bell et al., 2020).
As stated in the Contract, existing deposits within the corrugated steel culvert will be removed and disposed of off-site, with the corrugated invert being cleaned back to bare steel using hand held tools. The exposed steel under the proposed concrete lining shall be treated with a corrosion inhibitor followed by an anti-corrosion steel primer. All shotcreting works shall be undertaken in accordance with ‘BS EN 14487: Sprayed Concrete – Execution’.
The installation of the culvert invert lining will be carried out during low water conditions in the months of July to September inclusive.
The Contractor’s method statement details how the works will be carried out in the works sequence. The Contractor’s method statement is included in Appendix B and is summarised in the text below.
The proposed project is anticipated to last approximately 2 weeks. The existing carriageway over the culvert shall always remain in service.

Typical sequence of works
The sequence of proposed works is sourced from the contractor’s method statement and detailed below: -
• In relation to existing bed gravels immediately upstream and downstream of structure: Existing river bed gravels shall be retained. Lay Terram 2000GT on existing riverbed gravel and construct temporary 300mm thick clean Class 6F granular capping over to form working platform. On completion of the works remove the granular working platform and geotextile. Supplement the existing gravels to IFI requirements local to the culvert ends;
• Excavator to be tracked down the path from the road to the river;
• Existing concrete lining to be broken from culvert using breaker on 1.5T machine;
• Broken out material to be removed using excavator, shovels and wheel barrows. Kango hammer to be used where necessary;

o The washing unit generator will be positioned in the works area on the road with the lance hose running down the bank into the mouth of the culvert.
o The washing will commence on upstream side, washing in the downstream direction.
o It is predicted that the power washing will remove all loose / decayed material but if required small angle grinders and wire brushes will be used to remove any small pockets that remain. This area will then be power washed again to ensure it is completely clean.
o A silt fence will be erected at the outfall of the culvert on the downstream side to ‘filter’ the resultant water from the washing of the steel lining.
o Arisings from the cleaning of the culvert lining will be collected within the culvert and disposed of off-site to a Conhor construction tip.
o A small pump will then be placed on the down – stream side to pump the water into the area between Dam 2 and Dam 3.
o A layer of silt fencing will be wrapped around the intake pipe of the pump as an additional filter layer and the outfall will have a de-watering bag placed around the end of hose.
• Nominal 200mm Thick C25/30 Shotcrete Lining with A393 Stainless Steel Mesh Reinforcement to 1.3 diameter height.

1.2.2. Hydraulic Assessment
A hydraulic impact assessment was prepared for the proposed project. The hydraulic assessment report is included in Appendix C. The hydraulic assessment was conducted to analyse the impact of the proposed lining on the culvert’s flow capacity, change in predicted water levels upstream and downstream of the culvert, and changes in the velocities during low flow events. The hydraulic model shows that the proposed works to the existing culvert will not have a significant impact on the hydrological and hydraulic regime of the watercourse. The hydraulic impact assessment supported a Section 50 licence application to the Office of Public Works (OPW). Section 50 consent has been obtained for the proposed project at Knockakip Culvert (Appendix D), granted on 19th March 2021. A recommendation of the consent was that the proposed project should be designed to be resistant to scour and erosion, especially in a flood situation. The design of the proposed project incorporates this recommendation.
The following conclusions, based on the hydrology estimations and further hydraulic model assessment for the baseline and proposed scenarios, were made in the hydraulic assessment for Knockakip culvert: -
• ‘This hydraulic capacity assessment has been prepared in consideration of the requirements under Section 50 of the Arterial Drainage Act 1945.
• IH124 methodology has been used to derive flows for QMED, Q100 and Q100C1 and their magnitudes are 1.639 m3/s, 3.438 m3/s and 4.125 m3/s, respectively.
• The proposed works, due to the reduced flow area and higher invert levels results in increase in water levels upstream of the Knockakip culvert. No changes in the maximum water levels are predicted at the downstream end of the culvert.
• For the three events analysed, the predicted increase in the maximum stage is in the range of 215 mm to 271 mm. The change due to the proposed works is within the OPW limit of 300 mm.
• A minimum freeboard of 1.90 m is available in the culvert under all conditions, and this meets the OPW minimum threshold criteria.
• During low flow conditions, there is sufficient depth of flow, above the recommended 150 mm water depth for fish passage. The proposed works is not expected to cause significant worsening of the present situation with regards to fish passage.
• To aid in smooth fish movement during low flows, placing large rocks and providing transition pools should be considered at the channel immediately downstream of the culvert in discussion with Inland Fisheries Ireland.
• No nearby properties are expected to be affected in the proposed scenario.’
As detailed above, a recommendation of the hydraulic assessment was for the provision of large rocks and pools in the channel immediately downstream of the culvert, in consultation with Inland Fisheries Ireland. Atkins consulted with Inland Fisheries Ireland (IFI) in May 2020. IFI were of the opinion that due to very little channel upstream of the culvert and the fact that the channel is unlikely to be fish bearing, such provisions were not necessary. Prevention of loss of sediment and cementitious material to the watercourse were raised as a concern during the proposed installation of the concrete invert. These concerns will be addressed through the implementation of measures detailed in the working methods, contractor’s method statement (Appendix B) and mitigation measures set out in Section 6.3 of this NIS.

2. Scope of Study
The proposed project was previously subject to Screening for AA, where TII determined that the proposed project required Appropriate Assessment.
Thus, the aim of this report is to provide supporting information to assist the competent authority to carry out an Appropriate Assessment with respect to the proposed project. 2.1. Legislative Context
Directive 92/43/EEC on the Conservation of Natural Habitats and Wild Fauna and Flora, known as the ‘Habitats Directive’ provides legal protection for habitats and species of European importance. Article 2 of the Directive requires the maintenance or restoration of habitats and species of European Community interest, at a favourable conservation status. Articles 3 – 9 provide the legislative means to protect habitats and species of Community interest through the establishment and conservations of an EU-wide network of sites known as European sites. European sites are Special Areas of Conservation (SACs) designated under the Habitats Directive and Special Protection Areas (SPAs) designated under the Conservation of Wild Birds Directive (79/409/EEC).
Articles 6(3) and 6(4) of the Habitats Directive set out the decision-making tests for plans or projects that could potentially affect European sites. Article 6(3) establishes the requirement for Appropriate Assessment: -
“Any plan or project not directly connected with or necessary to the management of the site but likely to have a significant effect thereon, either individually or in combination with other plans or projects, shall be subject to appropriate assessment of its implications for the site in view of the site's conservation objectives. In the light of the conclusions of the assessment of the implications for the site and subject to the provisions of paragraph 4, the competent national authorities shall agree to the plan or project only after having ascertained that it will not adversely affect the integrity of the site concerned and, if appropriate, after having obtained the opinion of the general public.”
Article 6 (4) deals with the steps that should be taken when it is determined, as a result of Appropriate Assessment, that a plan or project will adversely affect a European site. Alternative solutions, imperative reasons of overriding public interest (IROPI) and compensatory measures need to be addressed in this case. Article 6(4) states: -
“If, in spite of a negative assessment of the implications for the site and in the absence of alternative solutions, a plan or project must nevertheless be carried out for imperative reasons of overriding public interest, including those of a social or economic nature, the Member State shall take all compensatory measures necessary to ensure that the overall coherence of Natura 2000 is protected. It shall inform the Commission of the compensatory measures adopted.
Where the site concerned hosts a priority natural habitat type and/or a priority species, the only considerations which may be raised are those relating to human health or public safety, to beneficial consequences of primary importance for the environment or, further to an opinion from the Commission, to other imperative reasons of overriding public interest.” 2.2. Appropriate Assessment Process
Guidance on the AA process was produced by the European Commission (EC, 2001; 2018), which was subsequently used to develop guidance for Ireland by the Department of Environment, Heritage and Local Government in 2009 (DEHLG, 2009) and also by the National Parks and Wildlife Service in 20181 (NPWS 2018). These guidance documents set out a staged approach to complete the AA process and outlines the issues and tests at each stage. The stages outlined below are taken from the guidance document Appropriate Assessment of Plans and Projects in Ireland – Guidance for Planning Authorities (DEHLG, 2009).

Figure 2-1 - Appropriate Assessment Process (Source: DEHLG, 2009).
2.2.1. Screening for Appropriate Assessment
Screening is the process that addresses and records the reasoning and conclusions in relation to the first two tests of Article 6(3): -
i. Whether a plan or project is directly connected to or necessary for the management of the site, and ii. Whether a plan or project, alone or in combination with other plans and projects, is likely to have significant effects on a European site in view of its conservation objectives.
If the effects are deemed to be significant, potentially significant, or uncertain, then the process must proceed to Appropriate Assessment.
2.2.2. Appropriate Assessment
Appropriate Assessment considers whether the plan or project, alone or in combination with other projects or plans, will have adverse effects on the integrity of a European site, and includes any necessary mitigation measures.
The competent authority can only agree to the plan or project after having ascertained that it will not adversely affect the integrity of the site(s) concerned. If this cannot be determined, and where sufficient mitigation cannot be achieved, the alternative solutions need to be considered and the process proceeds to the consideration of alternative solutions.
2.2.3. Alternative Solutions
This examines any alternative solutions or options that could enable the plan or project to proceed without adverse effects on the integrity of a European site. The process must return to AA as alternatives will require assessment in order to proceed. Demonstrating that all reasonable alternatives have been considered and assessed, and that the least damaging option has been selected, it is necessary to examine whether there are imperative reasons of overriding interest (IROPI).
2.2.4. IROPI
This examines whether there are imperative reasons of overriding public interest for allowing a plan or project that will have adverse effects on the integrity of a European site to proceed in cases where it has been established that no less damaging alternative solution exists. Compensatory measures must be proposed and assessed, of which the Commission must be informed.
The AA process only progresses through each of the full process for certain plans and projects. For example, for a project not connected with the management of a European site and where no likely significant effects on a European site in view of its conservation objectives are identified, the process stops at Screening for AA. Throughout the process the precautionary principle must be applied, which requires that the conservation objectives of Natura 2000 should prevail where there is uncertainty (EC, 2001; 2018).

A desk study was carried out to collate information available on European sites in the vicinity of the proposed project. These areas were viewed using Google Earth, Google maps3 and Bing maps4 (last accessed on 28/05/2020).
The National Parks and Wildlife Service (NPWS) and National Biodiversity Data Centre (NBDC) online databases were reviewed concerning European sites and their features of interest in the vicinity of the proposed project. The Environmental Protection Agency (EPA) mapping5 system was used to identify any hydrological connection between the proposed project and European sites.
Locations and boundaries of all European sites within 15km of the proposed project were identified and reviewed using the NPWS online map viewer. Boundary shapefiles were also downloaded from this site to facilitate the preparation of project graphics.
Desktop information on relevant European sites were reviewed on the NPWS website, including the site synopsis for each SAC/SPA, the conservation objectives, the site boundaries as shown on the NPWS online map viewer, the standard Natura 2000 Data Form for the SAC/SPA which details conditions and threats of the sites, and published information and unpublished reports on the relevant European sites.
Relevant planning information for the surrounding area was reviewed using the planning enquiry systems of Kerry County Council. Search criteria were implemented to determine whether such projects or plans that would not be relevant to this study. This information was used to determine potential cumulative impacts from other plans / projects with the proposed works.

3.2.1. Geographical Information System
Under the Munster Bridges Term Maintenance Contract No. 3, Atkins developed a Geographic Information System (GIS) to store all ecological data relating to the Munster bridges and to facilitate easy interrogation of data both within the dataset and spatially. The GIS was used during the assessment of the 16 structures proposed for the installation of concrete inverts for geospatial analysis of all data using MapInfo V. 16. This included the examination of the locations and boundaries of European sites within 15km of all structures and determination of surface water connectivity between structures and European sites, using the EPA’s river network data.
Under the Munster Bridges Term Maintenance Contract No. 3, Atkins submitted a data request to NPWS regarding freshwater pearl mussel Margaritifera margaritifera. This dataset was also used in the GIS. 3.3. Site Visit
An ecological walkover survey of the site was conducted by an Atkins ecologist during September 2019. The purpose of the survey was to survey the site for invasive plant species and to record the habitats and flora in the vicinity of the proposed project. The survey was chiefly concerned with recording the presence or likely presence of protected species and recording protected habitats or those habitats suitable to support protected species, in particular qualifying interests of European sites. The survey had regard for guidance sources such as NRA (2009) and Smith et al. (2011).
Aerial photos and site maps assisted the ecological walkover survey. Mammals and birds were surveyed based on incidental sightings, signs of activity during the survey and the identification of possible suitable habitats to support these species. Habitats were classified and named according to Fossitt (2000). During the ecological survey the presence of invasive plant species such as Japanese knotweed Reynoutia japonica, Himalayan balsam Impatiens glandulifera and Giant Hogweed Heracleum mantegazzianum were recorded. 3.4. Consultation
Consultation took place with IFI and the OPW regarding the proposed installation of the concrete invert at Knockakip culvert. Concerns raised by IFI were in relation to the loss of sediment and cementitious material to the watercourse during the installation of the proposed concrete invert, which are addressed in the working methods, contractor’s method statement (Appendix B) and mitigation measures set out in Section 6.3 of this report. Consultation with the OPW was with respect to the findings of the hydraulic assessment (Appendix C). Section 50 consent has been obtained for the proposed project at Knockakip Culvert (Appendix D). 3.5. Statement of Authority

4. Existing Environment 4.1. Desktop Review
Knockakip Culvert carries the Ballyduff stream under the N21 road from Castleisland to Abbeyfeale. The Ballyduff stream is a first order stream that originates from Knockakip Hill within the Stack’s Mountain range.
The Ballyduff stream flows for approximately 6km in a north-east direction where it joins the Owveg river. The Owveg River is a tributary of the River Feale. The River Owveg-Feale confluence is located approximately 13km downstream of Knockakip Culvert.
The Ballyduff stream and the Owveg and Feale rivers are categorised as ‘Good’ status under the Water Framework Directive (WFD).
IFI’s Water Framework Directive monitoring of the River Feale and River Owveg have recorded the following species; salmon, brown trout, sea trout, European eel, lamprey sp., and minnow6. O’Connor (2006) has also conducted surveys for juvenile lamprey in the Feale catchment. River/brook lamprey were confirmed from the Owveg catchment. Sea lamprey were only recorded in the downstream reaches of the River Feale and were not recorded in the Owveg catchment. During consultation IFI commented that there is very little channel available upstream of the culvert and it is unlikely that it is fish bearing.
Otter spraints was recorded on the Ballyduff Stream approximately 400m downstream of Knockakip Culvert during the Otter Survey of Ireland (Chapman & Chapman, 1982). It was noted that the stream was small with good cover, however that few aquatic prey items were likely to be available for otter. There are no road kill records for otter in the vicinity of the culvert on the Road Kill Survey 2020 database7. 4.2. Site Visit
Knockakip culvert carries the N21 over the Ballyduff stream. The culvert is located in a rural setting. A small area of broadleaved woodland, which boarders a conifer plantation, is located immediately upstream of the culvert. The broadleaved component is dominated by willow Salix spp. with an understorey of ivy Hedera hibernica, bramble Rubus fructicosus and ferns (Polypodiopsida). A maintenance access track is present upstream of the culvert on the left-hand side, which is lined with bramble, willowherb Epilobium sp. and gorse Ulex sp.. The channel substrate upstream of the culvert was gravel, sand and cobble (in order of dominance).
Downstream of the structure, a significant drop of approximately 1m to the riverbed is present. This drop is a significant barrier to fish passage.
On the left bank Japanese knotweed Reynoutia japonica was recorded. The area of the Japanese knotweed was approximately 5m x 8m in size. Both old stems and new growth was noted. Downstream of the Japanese knotweed, the river bank was dominated by ivy, ferns, herb-robert Geranium robertianum, montbretia and a large Sycamore tree. The vegetation of the right bank downstream of the culvert consisted of herb-robert, ferns, bramble, grasses, rushes and willow. The channel substrate upstream and downstream of the culvert was cobble, gravel and sand (in order of dominance). Mosses were the dominant instream vegetation.
A small stream or spring was present on the right bank, approximately 5m downstream of the culvert.
Otter spraints were present on the downstream side of the culvert. One sprainting site was recorded with 2 spraints present; 1 old and 1 fresh spraint. No otter holts were recorded in the vicinity of the culvert.

5. Screening for Appropriate Assessment
5.1. Connectivity of Proposed Project to European Sites
The ‘zone of influence’ (ZoI) for a project is the area over which ecological features may be subject to significant effects as a result of the proposed project and associated activities. This is likely to extend beyond the project site, for example where there are ecological or hydrological links beyond the site boundaries. The zone of influence will vary for different ecological features depending on their sensitivity to an environmental change (CIEEM, 2019).
A distance of 15km is recommended in the case of plans, as a potential zone of influence and this distance is derived from UK guidance (Scott Wilson et al., 2006). However, for projects the distance could be much less, and in some cases less than 100m. National Parks and Wildlife Service guidance8 advises that this must be evaluated on a case-by-case basis with reference to the nature, size and location of the project, the sensitivities of the ecological receptors, and the potential for in-combination effects.
Thus, given the nature, scale and extent of the proposed project, the potential zone of influence will consider European sites with regard to the location of a European site, the QIs of the site and their potential mobility outside that European site, the Cause-Pathway-Effect model and potential environment effects of the proposed project.
5.1.1. Special Areas of Conservation
Knockakip Culvert does not lie within a Special Area of Conservation (SAC).
There is one SAC within 15km of the proposed project; Lower River Shannon SAC (002165). The proposed project is hydrologically connected to the SAC, as its upper boundary lies approximately 2.6km d/s of the culvert on the Ballyduff stream. The Lower River Shannon SAC is a very large site, which is designated for a diverse range of habitats and species, not all of which are relevant to Knockakip Culvert and the Ballyduff stream. Due the surface water connectivity between the proposed project and the SAC, the Lower River Shannon SAC falls within the potential zone of influence of the proposed project.
5.1.2. Special Protection Areas
Knockakip Culvert does lie with a Special Protection Area (SPA); Stack’s to Mullaghareirk Mountains, West Limerick Hills and Mount Eagle SPA (004161). The SPA is designated for Hen Harrier Circus cyaneus.
The proposed project on the N21 will not result in loss or disturbance of supporting habitat regarding nesting sites and hunting ground for Hen Harrier, which is typically open bog, moorland, young conifer plantation and hill farmland (NPWS, 2015). Thus, given the nature and extent of the proposed works and the location of the structure on the N21, likely significant effects to the SPA are not anticipated. Thus, likely significant effects are not anticipated as a result of the proposed project and thus, this SPA is not considered further in this assessment.

5.2. Brief Description of European sites
5.2.1. Lower River Shannon SAC (002165)
NPWS (2013) site synopsis describes the site as follows: -
“This very large site stretches along the Shannon valley from Killaloe in Co. Clare to Loop Head/ Kerry Head, a distance of some 120 km. The site thus encompasses the Shannon, Feale, Mulkear and Fergus estuaries, the freshwater lower reaches of the River Shannon (between Killaloe and Limerick), the freshwater stretches of much of the Feale and Mulkear catchments and the marine area between Loop Head and Kerry Head. Rivers within the sub-catchment of the Feale include the Galey, Smearlagh, Oolagh, Allaughaun, Owveg, Clydagh, Caher, Breanagh and Glenacarney. Rivers within the sub-catchment of the Mulkear include the Killeenagarriff, Annagh, Newport, the Dead River, the Bilboa, Glashacloonaraveela, Gortnageragh and Cahernahallia.
Freshwater rivers have been included in the site, most notably the Feale and Mulkear catchments, the Shannon from Killaloe to Limerick (along with some of its tributaries, including a short stretch of the Kilmastulla River), the Fergus up as far as Ennis, and the Cloon River. These systems are very different in character: the Shannon is broad, generally slow flowing and naturally eutrophic; the Fergus is smaller and alkaline; while the narrow, fast flowing Cloon is acid in nature. The Feale and Mulkear catchments exhibit all the aspects of a river from source to mouth. Semi-natural habitats, such as wet grassland, wet woodland and marsh occur by the rivers, but improved grassland is the most common habitat type. One grassland type of particular conservation significance, Molinia meadows, occurs in several parts of the site and the examples at Worldsend on the River Shannon are especially noteworthy. Here are found areas of wet meadow dominated by rushes (Juncus spp.) and sedges (Carex spp.), and supporting a diverse and species-rich vegetation, including such uncommon species as Blue-eyed Grass (Sisyrinchium bermudiana) and Pale Sedge (C. pallescens). Floating river vegetation characterised by species of water-crowfoot (Ranunculus spp.), pondweeds (Potamogeton spp.) and the moss Fontinalius antipyretica are present throughout the major river systems within the site. The rivers contain an interesting bryoflora with Schistidium alpicola var. alpicola recorded from in- stream boulders on the Bilboa, new to Co. Limerick.
Five species of fish listed on Annex II of the E.U. Habitats Directive are found within the site. These are Sea Lamprey (Petromyzon marinus), Brook Lamprey (Lampetra planeri), River Lamprey (Lampetra fluviatilis), Twaite Shad (Allosa fallax fallax) and Salmon (Salmo salar). The three lampreys and Salmon have all been observed spawning in the lower Shannon or its tributaries. The Fergus is important in its lower reaches for spring salmon, while the Mulkear catchment excels as a grilse fishery, though spring fish are caught on the actual Mulkear River. The Feale is important for both types. Twaite Shad is not thought to spawn within the site. There are few other river systems in Ireland which contain all three species of lamprey. Two additional fish species of note, listed in the Irish Red Data Book, also occur, namely Smelt (Osmerus eperlanus) and Pollan (Coregonus autumnalis pollan). Only the former has been observed spawning in the Shannon.
5.2.1.1. Features of Interest
Due to the size and geographic range of the Lower River Shannon SAC, not all qualifying interests of the SAC are within the zone of influence (ZoI) of the proposed works. Table 5-1 below outlines the qualifying interests of the SAC that are within the ZoI of the proposed project on the Ballyduff stream, Co. Kerry.
Thus, the qualifying interests of the SAC that are within the ZoI of the proposed project are: -
• Water courses of plain to montane levels with the Ranunculion fluitantis and Callitricho-Batrachion vegetation [3260]
• Margaritifera margaritifera (Freshwater Pearl Mussel) [1029]
• Lampetra planeri (Brook Lamprey) [1096]

5.2.1.2. Conservation Objectives
The conservation objectives of the qualifying interests within the ZoI of the proposed works are broadly summarised below: -
• To maintain the favourable conservation condition of Water courses of plain to montane levels with the Ranunculion fluitantis and Callitricho-Batrachion vegetation [3260] in the Lower River Shannon SAC.
• To restore the favourable conservation condition of Freshwater Pearl Mussel in the Lower River Shannon SAC.
• To maintain the favourable conservation condition of Brook Lamprey in the Lower River Shannon SAC.
• To maintain the favourable conservation condition of River Lamprey in the Lower River Shannon SAC.
• To restore the favourable conservation condition of Salmon in the Lower River Shannon SAC.
• To restore the favourable conservation condition of Otter in the Lower River Shannon SAC.
5.2.1.3. Potential Threats to the Lower River Shannon SAC
The site synopsis for the Lower River Shannon SAC describes the land use and management within the site as follows: -
“There is a wide range of land uses within the site. The most common use of the terrestrial parts is grazing by cattle, and some areas have been damaged through over-grazing and poaching. Much of the land adjacent to the rivers and estuaries has been improved or reclaimed and is protected by embankments (especially along the Fergus estuary). Further, reclamation continues to pose a threat, as do flood relief works (e.g. dredging of rivers). Gravel extraction poses a major threat on the Feale.
In the past, cord-grass (Spartina sp.) was planted to assist in land reclamation. This has spread widely and may oust less vigorous colonisers of mud and may also reduce the area of mudflat available to feeding birds.
Domestic and industrial wastes are discharged into the Shannon, but water quality is generally satisfactory, except in the upper estuary where it reflects the sewage load from Limerick City. Analyses for trace metals suggest a relatively clean estuary with no influences of industrial discharges apparent. Further industrial development along the Shannon and water polluting operations are potential threats.
Fishing is a main tourist attraction on the Shannon and there are a large number of angler associations, some with a number of beats. Fishing stands and styles have been erected in places. The River Feale is a designated Salmonid Water under the E.U. Freshwater Fish Directive. Other uses of the site include commercial angling, oyster farming, boating (including dolphin-watching trips) and shooting. Some of these may pose threats to the birds and dolphins through disturbance. Specific threats to the dolphins include underwater acoustic disturbance, entanglement in fishing gear and collisions with fast moving craft.”

6. Appropriate Assessment 6.1. Introduction
This section of the report assesses the European site in more detail and examines where likely significant effects may arise. Where these effects are identified that may affect the integrity of the SAC, avoidance and mitigation measures are proposed to offset these effects. These are discussed below in the following sections. 6.2. Impact Evaluation
6.2.1. ‘Do Nothing’ Impact
In the case of the proposed project the ‘do nothing’ approach would be not to repair the existing culvert and not install the concrete invert to its base. In the absence of the proposed project, Knockakip culvert will continue to convey flows under the N21. As the existing culvert is experiencing corrosion, in the absence of repair works, this corrosion will continue and may ultimately result in structural failure of the culvert.
The existing culvert may present an artificial barrier to fish migration, however the length of channel upstream of the culvert is relatively short. During consultation IFI commented that there is very little channel available upstream of the culvert and it is unlikely that it is fish bearing. The ‘do nothing’ approach would result in the status of the culvert regarding fish passage remaining unchanged.
Knockakip culvert is located ca. 2.6km upstream of the Lower River Shannon SAC. Otter from the SAC could travel upstream and travel through the culvert. Given the nature of Knockakip culvert, the sides of the culvert are dry at normal flows. Therefore, otter can freely pass through the culvert during normal flows. It is possible that during high flows, where the sides of the culvert are no longer dry, otter may not be able to travel through the culvert and may access the N22 road as a result. The proposed project is for the installation of a concrete invert at Knockakip culvert. The hydraulic assessment demonstrates that the proposed project will not significantly affect the hydrological regime of the watercourse, nor the capacity of the culvert. Therefore, the installation of the concrete invert will not change the conditions under which Knockakip culvert is passable to otter.
6.2.2. Potential impacts during the works
In summary and as outlined in Section 5 above, the features of interest that are within the zone of influence of the proposed project are: -
• Water courses of plain to montane levels with the Ranunculion fluitantis and Callitricho-Batrachion vegetation [3260]
• Margaritifera margaritifera (Freshwater Pearl Mussel) [1029]
• Lampetra planeri (Brook Lamprey) [1096]
• Lampetra fluviatilis (River Lamprey) [1099]
• Salmo salar (Salmon) [1106]
• Lutra lutra (Otter) [1355]
The attributes and targets for the conservation objectives of the qualifying interests within the zone of influence of the proposed project listed above are set out in Table 6-1. The proposed project is not located within th catchment.
5162555DG023 | 5 | 19/03/2021 Atkins | 5162555DG0023 rev 5 - Knockakip NIS.docx Page 23 of 44
6.2.2.1. Direct impacts
As the proposed project is located approximately 2.6km upstream of the SAC boundary, given the nature and extent of the proposed project, direct impacts to the qualifying interests of the Lower Shannon River SAC will not occur during the construction phase of the proposed project.
6.2.2.2. Indirect impacts
The site of the proposed project is hydrologically linked to the SAC via surface water pathways. The mobilisation of silts, nutrients, hydrocarbons and concrete materials, could potentially occur during the works. Spillages of products in their liquid state, e.g. primer products, could also potentially occur during the works.
The release and entry of these materials to the Ballyduff stream has the potential to result in localised impacts of sedimentation and increased algal and macrophyte growth in the watercourses downstream, which in turn could impact on the aquatic biota that the river supports and hence, its ecological status.
Qualifying interests such as salmon, lamprey and freshwater pearl mussel may be impacted by the release of sediments as they are sensitive to changes in water quality. Mobilisation of sediments may affect lamprey and salmon spawning beds due to sedimentation of river substrates and the increase of fine sediments to spawning habitats. Fish spawning habitat is generally near suitable freshwater pearl mussel habitat. Freshwater pearl mussel requires very good water quality with cobble and gravel substrate containing very little fine sediment, and algal and plant growth. Floating river vegetation is also sensitive to siltation and changes in substrate composition as this affects the rooted structure of the plants and their ability to photosynthesise.
The potential impacts to species such as salmon and lamprey may also indirectly affect otter and the availability of a food source (fish biomass). Salmon and lamprey are important food sources for otter and a decline in these would have an indirect negative impact on otter.
The potential entry of polluting materials such as hydrocarbons and concrete material into the Ballyduff stream would have a negative impact on all aquatic qualifying interests of the SAC.
Due to the presence of site staff at the culvert for 2 weeks, i.e. the duration of the works, there is potential for temporary disturbance of otter that may travel upstream from the SAC. However, given the scale, extent and duration of the works, this impact is not anticipated to be significant. The dam setup will not cause fragmentation of the riparian corridor and thus, otter will be free to travel through the culvert. However, it is acknowledged that this will most likely be when the work crew is not present at the site, i.e. at the end of each working day until the following morning when works re-commence and at weekends.
Japanese knotweed is present on the downstream left riverbank. It is important that avoidance measures and biosecurity measures are implemented during the works to ensure that the area of Japanese knotweed on the downstream left bank is not disturbed. It is important to note that the area of Japanese knotweed is located on the riverbank, and slightly set back from the channel edge. Therefore, the rhizomes of the Japanese knotweed plants are contained within the soils of the riverbank and not within the instream working area.
6.2.3. Potential impacts post completion of the works
As shown by the hydraulic impact assessment, the proposed repair works to the existing culvert will not impact on the hydrological and hydraulic regime of the watercourse. The installation of the concrete invert at Knockakip Culvert will not alter the conditions under which the culvert is passable to otter, nor will it alter the status of the culvert regarding fish passage. The operation of the proposed project will not generate further emissions to the watercourse.

6.2.4. In-combination Impacts
In-combination impacts with the following plans and projects were considered during the preparation of this report. The search of Kerry County Council was based on a map-based search.
Kerry County Development Plan sets out strategies and objectives to provide sustainable development within Co. Galway. The Plan contains several natural heritage and biodiversity policies, which includes the protection of international and national designated sites, protect existing green infrastructure and provide additional green infrastructure, and the eradication of invasive species. A Natura Impact Report was prepared for the Plan, which assessed the Plan regarding its potential to adversely affect the integrity of European sites. The findings of the AA were integrated into the Plan, ensuring that potential adverse effects have been and will be avoided, reduced or offset. Thus, an AA determination was made by Kerry County Council that the Plan is not foreseen to have any adverse effects on the ecological integrity of any European Site. The current NIS is being prepared to ensure that the proposed project will not have an adverse impact on the integrity of European sites. Given the elements outlined above, the County Development Plan is not anticipated to act in-combination with the proposed project.
Projects that have been granted planning permission in the vicinity of Knockakip culvert, Ballyduff stream and the Owveg River include retention of existing developments, typically extensions to domestic dwellings, or the construction of new domestic dwellings or extensions to such dwellings. Regarding potential impacts to water quality, these projects will have to comply with the EPA’s Code of Practice for Wastewater Treatment Systems for Single Houses (EPA, 2009; 2018).
The 3 Groupings of culverts proposed for repair works in the Munster region (Table 1-1) are in the WFD catchments Tralee Bay – Feale, Suir, and Laune – Maine – Dingle Bay respectively. The proposed project is in the Tralee Bay – Feale catchment that drains to the Lower River Shannon SAC. The culverts in Group 2 and Group 3 are in separate WFD catchments to Group 1 and these WFD catchments do not drain to the Lower River Shannon SAC. Therefore, in-combination effects between the proposed project and other proposed culvert projects will not occur.
The OPW has an arterial drainage scheme in the Feale catchment, however the extent of the drainage scheme is in the lower section of the Feale catchment. The upper extent of the drainage scheme on the River Feale is Listowel town, which is located approximately 20km downstream of Abbeyfeale. Thus, in-combination effects with the OPW drainage programme of the Feale scheme and the proposed project are not anticipated.
Farmers and landowners may also undertake general agricultural operations in areas adjacent to the proposed project and along the river, which could potentially give rise to impacts of a similar nature to those arising from the proposed project. This could potentially result in additional an increased risk to water quality. Many agricultural operations are periodic, not continuous in nature, and qualify as a Notifiable Action that requires consultation with National Parks and Wildlife Service in advance of the works e.g. reclamation, infilling or land drainage within 30m of the river, removal of trees or any aquatic vegetation within 30m of the river, and harvesting or burning of reed or willow (NPWS, 2018). Agricultural operations must also comply with the EC (Environmental Impact Assessment) (Agriculture) Regulations 2011 and amendment 2017 S.I. No. 456/2011 and 407/2017 in relation to activities covered by the regulations;
• restructuring of rural land holdings,
• commencing use of uncultivated land or semi-natural areas for intensive,
• land drainage works on lands used for agriculture.
A Natura Impact Statement is required under Regulation 9 if it is likely to have a significant effect on a European designated site. The drainage or reclamation of wetlands is controlled under the Planning and Development (Amendment) (No. 2) Regulations 2011 and the European Communities (Amendment to Planning and Development) Regulations 2011. Therefore, the in-combination effects of agricultural operations and the proposed project are not likely to be significant.

6.3. Mitigation Measures
This section describes the mitigation measures required to ensure there are no residual effects on the integrity of the Lower River Shannon SAC. Table 7-1 summaries how these mitigation measures will result in no adverse effect on the integrity of European sites.
6.3.1. General Measures
1. An Ecological Clerk of Works (ECoW) will be appointed and will supervise all aspects of the critical works on site, in particular initial site set up, dam/ silt fence installation, pouring of concrete and use of chemicals. The ECoW will be a suitably qualified and experienced ecologist, which will be appointed by TII. The ECoW will ensure compliance of mitigation measures on site and liaise with IFI and NPWS staff where required.
2. A pre-construction survey for otter will be carried out upstream and downstream of the culvert within one month of commencement of works on site.
3. In accordance with the NRA guidelines, the following guidelines shall be followed: -
• No physical damage or disturbance to an otter holt shall occur.
• No works shall be undertaken within 150m of any holt at which breeding females or cubs are present.
• No wheeled or tracked vehicles should be used within 20m of an active non-breeding holt.
4. If an otter holt is recorded during the pre-construction survey and is likely to be damaged or disturbed by the proposed works, a derogation licence will be applied for from NPWS. Any further mitigation measures required by the derogation licence shall be implemented.
5. The proposed works shall be carried out during July 1st to September 30th inclusive.
6. The site manager shall monitor the 10-day weather forecast. The works shall not take place during high river flows or prior to forecasts of heavy rainfall. High river flows constitute river flows that will top the dams or will be in excess of pumping capabilities. If such conditions are forecast, the works area shall be secured and all materials, including the elements of the dam system (sandbags, silt fences, pumps and associated pipes and silt socks) will removed from the works area and riverbanks. Upon subsidence of flows, the dam system shall be re-instated upstream and downstream of the culvert and the works area de-watered before works can re-commence. This shall be supervised by the ECoW.
7. A Temporary Traffic Management zone will be created within the road corridor. This shall be used for parking and deliveries of materials.
8. All site staff will be informed of best practice methodologies to be employed on site via the dissemination of a tool-box talk. This shall include the requirement for protection of aquatic habitats, the sensitivity of the Lower River Shannon SAC and the presence of Japanese knotweed immediately downstream of the culvert.
9. Works will be carried out during day-time hours, except in the event of an emergency.
10. Any chemical, fuel and oil stores will be located on an impervious base within a secured bund with a storage capacity 110% of the stored volume.
11. Biodegradable oils and fuels will only be used.
12. Drip trays will be placed underneath any standing machinery to prevent pollution by oil/fuel leaks. Where practicable, refuelling of vehicles and machinery will be carried out on an impermeable surface in one designated area well away from any watercourse or drainage (at least 20m).
5162555DG023 | 5 | 19/03/2021 Atkins | 5162555DG0023 rev 5 - Knockakip NIS.docx Page 29 of 44
13. Emergency spill kits will be available on site and staff will be trained in their use. A reporting system will be established on site to record accidents and/or spillages on site and the resultant action taken to remedy the incident.
14. Operators will check all equipment, machinery and vehicles on a daily basis before starting work to confirm the absence of leakages. Any leakages should be reported immediately and addressed.
15. Daily checks will be carried out and records kept on a weekly basis and any items that have been repaired/replaced/rejected noted and recorded. Any items of plant machinery found to be defective will be removed from site immediately or positioned in a place of safety until such time that it can be removed. All items of plant will be checked prior to use before each shift for signs of wear/damage.
6.3.2. Specific Measures
16. A dry working area will be achieved by setting up a dam system. There shall be three dams in total; one upstream of the culvert and two downstream of the culvert. Each dam will consist of tightly packed sandbags that are filled with clean sand. The sandbags will be double lined and individually sealed. Only sealed sandbags will be used to create the dams. No clay or soil material is permitted to ‘seal’ the sandbag dams. If needed, a geotextile membrane will be used to enhance the seal of the dams.
17. The integrity of the sandbag dams must be monitored to ensure that the works area is isolated from the live channel. This shall be monitored by the site manager twice daily; in the morning before the commencement of works and at the end of the day prior to leaving site.
18. Two silt fences shall be installed between the two sandbag dams situated downstream of the culvert. Any water pumped into this dammed area shall be in advance of the silt fences. Thus, all water pumped from the work area must pass through both silt fences before re-entering the river.
19. The pipe used to flume flows through the works area will be fitted with a filter to ensure no fish enter the pipe. The outfall of the pipe will be fitted with a silt sock. The silt sock shall be changed and/ or cleaned at regular intervals. The interval for replacing the silt sock will be dependent on the turbidity of the watercourse and therefore this shall be monitored by the site manager twice daily at a minimum; in the morning before the commencement of works and at the end of the day prior to leaving site.
20. The temporary working platform, i.e. terram and 300m thick class 6F granular capping, must be clean and free of any foreign debris before being installed on the existing riverbed gravels.
21. There can be no entry of debris and / or waste material from the works area to the live channel. The debris must be collected within the dry work area, removed from the work area and disposed of appropriately off site at Conhor Construction tip in Ballincollig, Cork.
22. Powerwashing of the culvert will not involve any water abstraction from the river. Water will be brought to site in a bowser by the Contractor. Power washing can only take place when the sandbag dam system and silt fences are in place. The wash unit generator will be positioned on the road and the lance hose will run down the bank into the work area.
23. Any water arising in the work area, as a result of power washing or seepage through the upstream dam, will be pumped from the working area into the area between the two downstream dams in advance of the silt fences. The pump will be located on the temporary working platform and fitted with a drip tray. All associated pipes will be fitted with a silt sock and/ or de-watering bag.
24. Primer products shall be applied to surfaces in the morning of a workday. This is to ensure that the required 6-hour curing time can be achieved before leaving the site at the end of the day. Primer products shall not be applied to surfaces within 48 hours of a heavy rain forecast.
25. Only quantities of primer products required for use in that working day shall be available at the site. These shall be kept is a bunded container located at least 20m from the watercourse until required for use.
5162555DG023 | 5 | 19/03/2021 Atkins | 5162555DG0023 rev 5 - Knockakip NIS.docx Page 30 of 44
26. The Shotcrete pump will be located on the road above the work area. The integrity of pump hoses must be checked prior to commencing works Pump hoses will be located within the dry work area to ensure no spillage of concrete to the live channel.
27. At no point will any equipment be washed out within the work area or adjacent to a watercourse.
28. Sandbag dam no. 3 and the silt fences shall be left in place until any sediment plume has dissipated.
29. The gravel area on which the temporary working platform was located will be loosened, as it may have been compacted during the works. This area will be reinstated with washed and clean gravel.
30. All material used on site, including the sandbags, silt fences, silt socks, de-watering bags and components of the temporary working platform, will be removed from site and disposed of at Conhor Construction tip in Ballincollig.
6.3.3. Biosecurity protocols
Japanese knotweed is present on the downstream side of Knockakip culvert. Facing downstream, Japanese knotweed is present on the left bank. The area is within 7m of the works area. Therefore, a 7m area will be fenced off, with the river side of the stand fenced-off along the edge of the watercourse. A tarpaulin sheet will be placed over the plant and tied down with rope, which will be attached to stone weights. Care will be taken not to break any parts of the Japanese stand while putting the tarpaulin sheet in place. This area will not be disturbed during the works. After the works, the tarpaulin must be inspected to make sure it is clean and free of any plant material before being removed from the site.
The stands of Japanese knotweed will be cordoned off and signage erected to denote that it is an area where no access is permitted. No access to this area will occur during the proposed project and this riverbank will not be used for the transport of sandbags or any other materials to and from the carriageway and culvert. All access hoses will come down the opposite bank, i.e. the right bank facing downstream.
A pre-construction invasive species survey will be conducted prior to the commencement of works on site. If any further invasive species are recorded, these shall be fenced off using a 7m buffer from the outermost edges of the invasive species plant(s).
Biosecurity protocols shall be implemented during the construction phase of the proposed project to prevent the introduction of invasive species listed on the third schedule of the EC (Birds and Natural Habitats) Regulations 2011 to site and the further spread of diseases.
1. All equipment intended to be used at the site shall be dry, clean and free from debris prior to being brought to site.
2. If drying out of equipment is not feasible, equipment should be either: -
i. power steam washed at a suitably high temperature or at least 65 degrees, or
ii. disinfected with an approved disinfectant, e.g. Virkon or an iodine-based product. It is important that the manufacturer’s instructions are followed and if required, the correct contact times are allowed for during the disinfection process. Items that are difficult to soak should be sprayed or wiped down with disinfectant.
3. During the duration of the proposed project, if equipment is removed off-site to be used elsewhere, the said equipment shall be cleaned and disinfected prior to being brought back to the works area of the proposed project.
4. Appropriate facilities shall be used for the containment, collection and disposal of material and/or water resulting from washing facilities of vehicles, equipment and personnel.
5. Importation of materials shall comply with Regulation 49 of the EC (Birds and Natural Habitats) Regulations 2011.

7. Conclusions
This NIS provides the competent authority with supporting information to undertake the Appropriate Assessment in relation to the proposed project at Knockakip Culvert and its potential indirect impacts via surface water pathways on the Lower River Shannon SAC.
The NIS has examined the potential impacts of the proposed project on the integrity of the SAC, alone and in combination with other plans and projects, taking into account the site’s structure, function and conservation objectives. Where potential likely significant effects were identified, mitigation measures have been recommended to assist in offsetting these effects.
Following a comprehensive evaluation of the potential direct, indirect and cumulative impacts on the qualifying interests of the SAC, and the implementation of the proposed mitigation measures, it has been concluded by the authors of this report that there will be no residual impacts and the proposed project will not have an adverse effect on the integrity of the Lower River Shannon SAC.
To confirm this conclusion, the following checklist taken from DEHLG (2009) has been completed.
Table 7-1 Checklist of Site Integrity (DEHLG, 2009).

Ecological Notes
• No re-fuelling can take place within 20m of the stream and can only take place using bowsers of delivery trucks. • Spill trays to be used when refueling • All refueling to take place within the site set up on the hard shoulder and not anywhere near the watercourse • Spill kits will be readily available on site • When entering the stream, and when leaving the, all operatives must wash down their wellingtons / waders and any tools that come into contact with the water with active Virkon
Page 1 of 21 CCF800/23 Rev 0 Aquatic. This will avoid the risk of any cross contamination when working on other bridges in other areas. • Operatives to be made familiar with Inland Fisheries Ireland Biosecurity Protocol 2010 prior to commencing the works to ensure all guidelines are followed • Sandbags to be placed as bund to dry area below area of impact to prevent any lime mortar entering the watercourse • All birds’ nests are protected by law. Nests which might be encountered under bridges include dipper and grey wagtail. The Dipper nests in closed / domed nests often located on supports under bridges. Kingfisher may also nest in sand banks close to bridges. Our ecologist will advise on general ecological questions as works progress. If a nest is discovered, the area is to be left undisturbed and the ecologist advice should be sought. If a known nesting site would be impacted be proposed repair works, mitigation in the form of artificial nest boxes must be provided. • There is Japanese knotweed on the d/s left bank. No works to be carried out within 7m of this. All access hoses to come down the opposite bank. This area is not to be disturbed and will be fenced off from the works area. This work will be carried under guidance from Cumnor’s Ecologist. •
Site Set Up
• TTMP set up No1 to be set up as per diagram below
• Site vehicles will park within the temporary traffic management set up on the hard shoulder • All materials will be stored within the TM set up

Water Management
1) The stream will be over-pumped through a flume that will be attached roof of the culvert at a high level. 2) The pump will be located in a shelf that will be dug into the slope above the culvert. 3) Life ring to be placed in full view on pole at edge of river 4) Sand to be brought to site in 1T Bags from Roadstone Classis. Sand to be clean building sand. 5) Approximately 60 no. hessian sand bags to be filled with sand and handed down to the river bed at upstream side of culvert 6) Sand bags should only be half filled with sand and tied & sealed to ensure no sand enters the watercourse 7) Bottom layer of sandbags should be “walked in” to riverbed to create good seal between sand bags and river bed 8) Sand bags to be built up in stretcher bond to desired height 9) There will be three dams erected in the stream; a. Dam 1 upstream of the culvert and dam 2 &3 situated downstream of the culvert (See above). b. Dam 2 and 3 will be erected first, 300mm high on the stream bed. c. Dam 1 will then be erected and the stream flow pumped downstream of dam 3. The intake will be fitted with a filter to ensure no fish enter the pipeline. d. The outfall pipeline will be fitted with a silt sock. This will dissipate flow and prevent scour of the river bed. e. The stream between dam 1 & 2 will be electro fished and the fish placed in the pool created between dam 2 and 3. f. On completion of the electro fishing dam 2 will be raised to full height and a silt fence will be erected between dam 2 and dam 3 and a second silt fence will be erected just upstream of dam 3. g. The water between dam 1 and dam 2 will be pumped into the pooled area between dam 2 and dam 3 in advance of the silt fences. h. A shallow sump will be excavated (or naturally occurring) in the stream bed upstream of dam 2 to catch surface water and cleaning water from power washing the culvert. i. The collected water in the sump will be pumped downstream between dam 2 and dam 3 and discharge in advance of the silt fences
Page 3 of 21 CCF800/23 Rev 0 10) The outlet pipe will be placed into a 225mm non perforated pipe installed through the culvert at high level. It will be secured by a temporary bracket that will be fixed to at high level along the culvert. 11) The bracket will consist of a threaded bar arrangement with unit strut drilled through the steel lining with an expanding anchor bolt fitting at the end to hold it in place. The threaded rod arrangement will allow for height adjustment to accommodate for a gravity fall on the pipe. 12) Sump and 2 inch pump to be set up on down stream side of culvert to pump away any excess water that has managed to get through the sandbag dam. This water is to be pumped into the area between dam 1 and dam 2 13) Cumnor will arrange consultation with IFI prior to mobilisation. Electrofishing requirement will be agreed upon at this consultation.

Typical sequence of works:
Page 4 of 21 CCF800/23 Rev 0 1. In relation to existing bed gravels upstream and downstream of structure : Existing river bed gravels shall be retained. Lay Terram 2000GT on existing riverbed gravel and construct temporary 300mm thick clean Class 6F granular capping over to form working platform. On completion of the works remove the granular working platform and geotextile. Supplement the existing gravels to IFI requirements local to the culvert ends.’ 2. Excavator to be tracked down path from road to river bed 3. Existing concrete lining to be broken from culvert using breaker on 1.5T machine 4. Broken out material to be removed using excavator, shovels and wheel barrows. Kango hammer to be used where necessary 5. Material to be disposed of in Conhor Construction Tip in Ballincollig 6. Power Washing of Culvert Lining: • The lining will be cleaned using a 25.000PSI Hydro Power Washer removing the loose / decayed material and exposing a clean Sa3 finish on the existing steel lining. • The washing unit generator will be positioned in the works area on the road with the lance hose running down the bank into the mouth of the culvert. • The washing will commence on upstream side, washing in the downstream direction. • It is predicted that the power washing will remove all loose / decayed material but if required small angle grinders and wire brushes will be used to remove any small pockets that remain. This area will then be power washed again to ensure it is completely clean. • A silt fence will be erected at the outfall of the culvert on the downstream side to ‘filter’ the resultant water from the washing of the steel lining. • Arisings from the cleaning of the culvert lining will be collected within the culvert and disposed of off site to a Conhor construction tip. • A small pump will then be placed on the down – stream side to pump the water into the area between Dam 2 and Dam 3. • A layer of silt fencing will be wrapped around the intake pipe of the pump as an additional filter layer and the outfall will have a de-watering bag placed around the end of hose. 7. Nominal 200mm Thick C25/30 Shotcrete Lining with A393 Stainless Steel Mesh Reinforcement to 1/3 diameter height

1. Introduction
Atkins has been commissioned by Transport Infrastructure Ireland (TII) in respect of National Roads bridges maintenance for Munster and North West regions of Ireland. As a part of this,45 corrugated steel culverts are proposed to be lined with concrete. This assessment is being done for the Knockakip culvert (Structure Ref ID: KY-N21-016) to analyse the impact of proposed lining on the culvert’s flow capacity and its impacts on the flood levels upstream and downstream of the culvert.
2. Site Location
The Knockakip culvert (Structure Ref ID: KY-N21-016) is located at the national primary road N21 near Castleisland in the County of Kerry, approximately 5.5 km north of Castleisland town as indicated in Figure 2-1 below.
Figure 2-1 - Knockakip culvert location
3. Existing Culvert Description
The Knockakip culvert is circular in shape and made up of corrugated steel metal. The upstream face of the culvert has a diameter 2.80 m, and the downstream face has diameter of 2.96 m. The cross sections upstream and downstream of the culvert have the river wider than the width of the culvert. The banks are mostly covered with grass and forest trees. The current condition of the culvert is shown in Figure 3-1. No significant silt deposition is evident from the figure. Figure 3-2 shows that the watercourse takes approximately a 90-degree bend to enter the Knockakip culvert.

4. Proposed Works
The proposed works consist of cleaning out the silt from the existing culvert and lining the culvert with 150mm thick reinforced concrete for the bottom-third of the culvert, as detailed in Figure 4-1. However, for the purpose of hydraulic assessment, the culvert has been assumed to be lined at the top as well, as discussed further in Section 6.2.

5. Catchment Description
The Knockakip culvert lies on an unnamed tributary to River Owveg, approximately 5 km upstream of its confluence with River Owveg. The catchment is small with area < 1 km2 and is completely rural. The outlet node of the ungauged catchment as taken from the FSU portal is about 100 m downstream of the Knockakip culvert (Location number: 23_2047_1). The Knockakip culvert drainage catchment and the culvert location are shown in Figure 5-1. The catchment descriptors from the FSU Portal for the subject site are tabulated in Table 5-1. The main stream is steep as can be noted from a high value of main stream slope (S1085 = 39.7263 m/km). The catchment is flashy and has low permeability (BFISOIL = 0.3389), and there is no attenuation due to lakes/reservoirs (FARL = 1). This indicates that the catchment has a quick response to the rainfall events. There is one property identified at the edge of the catchment. The N21 which is a primary road lies within the catchment. However, there is no historical flooding reported in the area (floodmaps.ie web portal)

5.1. Flow Assessment For the assessment of inflows to the hydraulic model, three different methods for flow estimation viz. Flood Studies Update (FSU), FSR3 and IH124 were used. Since the catchment area is small (<25 km2), the FSU method is not applicable. However, to obtain the catchment parameters and for comparative purposes, the FSU method was also considered.
Flood Studies Update (FSU) Programme Method The catchment that drains to the Knockakip culvert is smaller than the catchment used in the FSU Portal to compute QMED, with the latter having an additional area of 0.11 km2 downstream of the N21 road. To reduce the flow pro-rata by area, a multiplying factor has been applied to the QMED estimate, which is computed as below: 푐푎푡푐ℎ푚푒푛푡 푎푟푒푎 표푓 푡ℎ푒 푐푢푙푣푒푟푡 0.906 퐹푙표푤 푟푒푑푢푐푡𝑖표푛 푓푎푐푡표푟 = = = 0.892 푐푎푡푐ℎ푚푒푛푡 푓푟표푚 퐹푆푈 푃표푟푡푎푙 1.016
The PCD (physical catchment descriptors) rural estimate of QMED for the downstream ungauged outlet from the FSU Portal is 0.8664 m3/s, hence for the culvert upstream, QMED is calculated as 0.772 m3/s (0.8664 x 0.892). As the catchment is completely rural, only the rural estimates were taken for computation.
FSU QMED Estimation As the subject site is ungauged, pivot catchments were reviewed for hydrological similarity. However, all the pivot catchments were very big (>100 km2), and the closest hydrological similarity value computed was 5.1262 (recommended value is 1), hence all pivot catchments were rejected. Thus, the PCD (physical catchment descriptors) QMED estimate was applied with the standard factorial error of 1.37 (for 68% confidence interval - upper limit) to ensure that the flows are not underestimated, and the final QMED values was calculated to be 1.058 m3/s (0.772 x 1.37).
FSU 100yr Design Flow Estimation Pooled flood frequency analysis was performed for the subject site in the FSU Portal, and the growth factor for various flood frequencies was estimated as shown in the Figure 5-2 below.
Figure 5-2 - Growth factors from FSU Portal
The growth factor of 1.92 for 100-year design flood was used for the assessment. The upper limit of the standard error associated with growth factor in pooling analysis for EV1 distribution is 2%, and hence the error adjusted growth factor is 1.958. Finally, the 100-year flood (Q100) is calculated as 2.072 m3/s. A 20% uplift for climate change was applied to obtain 100-year flood with 20% climate change (Q100C1) as 2.486 m3/s. Table 5-2 summarizes the design flows for Knockakip culvert from the FSU analysis.

Institute of Hydrology Report No. 124 Method The Institute of Hydrology (IoH) Report 124 method was used for comparative purposes to determine the mean annual flow (QBAR), hence Q100 and Q100C1 were estimated for Knockakip culvert catchment. The Institute of Hydrology Report No.124 (IH 124) 3 parameter equation to determine mean annual flow (QBAR) is shown below: 0.89 1.17 2.17 푄퐵퐴푅푟푢푟푎푙 = 0.00108 퐴푟푒푎 푆퐴퐴푅 푆푂퐼퐿
A desktop study was carried out to determine the values of the parameters for the Knockakip culvert catchment. The soil for both the catchments was classified into Class 5 based on maps from the UKSUDS website. The description of parameters of the IoH 3-variable equation and the determined values for the catchment are listed in Table 5-3.

The values listed above were applied to the calculations, and the QBAR was calculated. Further, the standard factorial error of 1.65 (for 68% confidence interval) was applied and the estimate is shown in Table 5-4. For IoH 124 method, the growth factor for 1 in 100-year flood is 1.96 (Flood Studies Report). Thus, Q100 and Q100C1 are estimated and listed in Table 5-4.

For FSR3 method, the growth factor for 1 in 100-year flood is 1.96 (Flood Studies Report). Thus, Q100 and Q100C1 are estimated and listed in Table 5-5.

The flows determined using the three methods discussed in Sections 5.1.1, 5.1.2 and 5.1.3 were reviewed. The FSU analysis was carried out just for comparative purposes as it is applicable on catchment areas greater than 25 km2. The comparison of Q100 estimates (Table 5-6) from the other two different methods are comparable, thereby indicating the robustness and reliability of estimates for the study area. The FSR3 and IH124 methods are better suited for catchment sizes greater than 0.4 km2.
Table 5-6 - Comparison of Q100 estimates Event Flow (m3/s)
FSU 2.072
IH124 3.438
FSR3 3.243
IH124 method gives the conservative estimate for Q100 and is also relevant for the Knockakip catchment which has an area of 0.9 km2. Therefore, the flows computed using IH124 methodology was taken forward for hydraulic modelling. The QMED event corresponds to the median flood flow (1 in 2-year return period) and is a reasonable estimate for low flows as there is 50% exceedance probability. The QMED flow for IH124 method is estimated as: 푄퐵퐴푅 푄푀퐸퐷 = ⁄1.07 Thus, QMED is computed as (1.754/1.07) = 1.639 m3/s. The summary of flows taken forward for hydraulic modelling is listed in Table 5-7.

6. Development of Hydraulic Model
A 1D hydraulic model was developed for the tributary with the Knockakip culvert added. The purpose was to estimate the impact of the proposed lining on the culvert capacity, change in predicted water levels upstream and downstream, and changes in the velocities during the low flow events. Due to the uncertainty and limitations in hydrologic and hydraulic modelling along assumptions as listed in Section 6.2, the reader is advised to exercise caution and interpret the results as indicative changes in river channels levels due to the proposed works. The results should not be used for any direct assessment of flood risk in the region. 6.1. Hydraulic Model Selection Flood Modeller v4.5 was selected to construct the 1D hydraulic model for the study area. 6.2. Hydraulic Modelling Assumptions The following are the main assumptions in the hydraulic model development: 1. The channel roughness has been defined based on land use information provided in survey drawings 2. The shape of the culvert is assumed to be circular based on the survey information provided 3. Based on the information from survey, the culvert inlet unit was assumed to be a square headwall type (i.e. with no wingwalls), corresponding to circular corrugated metal conduits. 4. For model simplification, lining is assumed to be done all round inside the culvert 5. No silt deposition and no significant blockage at all conditions has been assumed for the modelled scenarios 6. A 90-degree bend with a head loss coefficient of 0.5 has been assumed at the upstream face of the culvert, based on the survey information. 6.3. Topographical Survey Data Topographical survey data from Murphy Surveys (2019) has been used to develop the hydraulic model. The data includes river cross sections and culvert and deck details. The survey covers the watercourse for a length of 241m upstream of the culvert, and 220 m downstream of the culvert. The extent of the survey and the survey data received are shown in Appendix A of the report. 6.4. Channel & Associated Bank Roughness Values No roughness values were provided with the survey data. Therefore, based on the survey information on the land use type, the roughness values were assigned. The channel consisted mostly of stones/ gravel and hence a Manning’s ‘n’ of 0.04 was used. For the banks, ‘n’ value of 0.055 and 0.06 was assigned to land use classes corresponding to grass/bog and forestry respectively. In the proposed scenario, the culvert is assumed to be lined entirely with reinforced concrete. Table 6-1 below lists the assigned Manning’s roughness values in the hydraulic models.

6.5. Boundary Conditions A constant flow boundary was applied at the upstream and a normal depth boundary was applied as the downstream boundary conditions. 6.6. Hydraulic Model Development A total channel length of 486 m along the unnamed tributary to the River Owveg was modelled. This includes river cross sections, the Knockakip culvert and the boundaries. Interpolated sections were added to the hydraulic model so that spacing between the cross-sections follows the rule of thumb, suggested by the software guidance notes for a given slope and typical depth (Samuels P.G, 1990). Also, Section KNK_11 provided in the survey data was removed as the section was not representative of the typical channel and banks in the watercourse. The location of cross sections used for hydraulic model development is shown in Figure 6-1. The cross sections and their relative positions to the culvert is tabulated in Table 6-2.

The survey data was used to develop a ‘baseline’ model representing the existing situation. The ‘baseline’ hydraulic model was further used to create a ‘proposed’ scenario model, where lining is provided in the culvert. Below are the changes in the ‘proposed’ scenario model. • Manning’s roughness value was updated to 0.012 for the bottom and top of the culvert to represent the concrete liner, considering that no silt will be deposited (also see assumption-5 under Section 6.2.) • The invert levels at the entry and exit, and diameter of the culvert were updated to reflect the 150mm thick concrete lining.

7. Analysis of Model Simulations
The baseline and proposed models were simulated under steady state mode for the following scenarios: • Impact of proposed works (Q100) • Impact of climate change (Q100C1) • Low flow condition (QMED) 7.1. Impact of Proposed Works The baseline and proposed hydraulic models were simulated for 1 in 100-year event to predict the impacts of proposed works. The maximum stage and depth results from hydraulic modelling for Q100 are presented in Table 8-1 and Table 8-2 respectively. A long section plot indicating the maximum stages along the watercourse for 1 in 100-year event is also shown in Figure 7-1.
Figure 7-1 - Long section plot -Q100
The results demonstrate that the impact due to lining is predicted only in the reach upstream of the culvert. For the 1 in 100-year event, the maximum increase in the water level is 258 mm. Of this 258 mm increase in water levels, 150 mm increase is due to raising the culvert invert levels by 150mm by installing the proposed lining. There is enough freeboard available (minimum 2.03m) in the proposed scenario, and the proposed works do not affect the water levels in the reach beyond 68 m upstream of the culvert. The N21 road is also not overtopped due to the lining works. There is one property identified at the edge of the catchment. As the flows are remaining in the channel, the property is not affected due to lining.

Hence, the proposed works to the Knockakip culvert will not have a significant hydraulic impact on the tributary and its main watercourse.
7.2. Impact of Climate Change The baseline and proposed hydraulic models were simulated for 1 in 100-year plus 20% climate change event. The purpose of these simulations was to assess whether the proposed lining works to the Knockakip culvert will have any hydraulic impacts under a climate change scenario. The maximum stage and depth results from hydraulic modelling for Q100C1 are presented in Table 8-1 and Table 8-2 respectively. The results of the simulation indicate that the maximum increase in the water level is 271 mm, of which 150 mm of the increase is due to raised invert levels of the culvert in the proposed scenario. There are no changes predicted downstream of the culvert. For the climate change scenario, which models the worst-case scenario for the catchment, there is enough freeboard available (1.98 m) for the proposed scenario. The maximum water level within the culvert remains at less than one-third of its opening height. Hence, the results indicate that no extra allowances are needed during proposed works to account for a climate change event. Therefore, the assumption of an all-round lining to the culvert does not impact the hydraulic results. There is one property identified at the edge of the catchment. As the flows are remaining in the channel, the property is not affected due to lining. 7.3. Impact on the Low Flows To assess the availability of water for fish passage during low flows, the hydraulic model was assessed for the QMED event. The flow depth is summarised in Table 8-2 and the velocity in Table 8-3. The modelling results in Table 8-2 suggest that for the baseline scenario, the depth of flow is 482 mm at the upstream and 280 mm at the downstream end of the culvert. The corresponding flow velocities are in the range of 2.32 m/s to 4.96 m/s for the upstream and downstream ends respectively (Table 8-3). From Table 8-2, it can be noted that the proposed works causes the flow depth at the upstream end of the culvert to reduce by 151 mm, to 331 mm. The corresponding increase in velocity is from 2.32 m/s to 4.25 m/s. At the downstream, the flow depth remains unchanged at 280 mm, with a small increase in velocity from 4.96 to 5.25 m/s. From the above analysis, the proposed works is not expected to cause significant worsening of the present situation. However, measures to reduce the exit velocity and increase the water levels at the channel immediately downstream of the culvert should be considered in discussion with Fisheries Ireland. This could be achieved by placing large rocks and providing transition pools at the downstream to drown the culvert inlet.
8. Conclusions
Based on the hydrology estimations, and further hydraulic model assessment for the baseline and proposed scenarios, following conclusions are made: • This hydraulic capacity assessment has been prepared in consideration of the requirements under Section 50 of the Arterial Drainage Act 1945. • IH124 methodology has been used to derive flows for QMED, Q100 and Q100C1 and their magnitudes are 1.639 m3/s, 3.438 m3/s and 4.125 m3/s respectively. • The proposed works, due to the reduced flow area and higher invert levels results in increase in water levels at upstream of the Knockakip culvert. No changes in the maximum water levels are predicted at the downstream. • For the three events analysed, the predicted increase in the maximum stage is in the range of 215 mm to 271 mm. The change due to the proposed works is within the OPW limit of 300 mm. • A minimum freeboard of 1.90 m is available in the culvert under all conditions, and this meets the OPW minimum threshold criteria

• During low flow conditions, there is sufficient depth of flow, above the recommended 150 mm water depth for fish passage. The proposed works is not expected to cause significant worsening of the present situation with regards to fish passage. • To aid in smooth fish movement during low flows, placing large rocks and providing transition pools should be considered at the channel immediately downstream of the culvert in discussion with Fisheries Ireland. • No nearby properties are expected to be affected in the proposed scenario.

I refer to the above Section 50 applications.
This application was received from Atkins Ireland Ltd on behalf of Transport Infrastructure Ireland and arises due to the proposed works for the Knockakip culvert on the N21 National Road.
The documentation submitted has been examined and I am to confirm that the consent of the Commissioners of Public Works under Section 50 of the Arterial Drainage Act, 1945 is given to the proposed culvert/bridge with the following recommendations:
Recommendation
1) The proposed works should be designed to be resistant to scour. This is the applicants/designers responsibility. 2) Detail design for the proposed scheme is the responsibility of the applicant. 3) It is the applicant’s responsibility to satisfy themselves that all works planned and undertaken are in compliance with all current environmental and ecological legislation.
It should be noted that consent is given only for the purpose of Section 50 and does not absolve the recipient of responsibility for any adverse effects caused by this installation to any third party.
The Commissioners of Public Works are not responsible and accept no liability for any loss or damage whatsoever caused as a result of this development.
Yours sincerely,
