1 Introduction 1.1 Project Background Offaly County Council and Westmeath County Council have jointly appointed Minogue and Associates to prepare an Environmental Impact Assessment (EIA) screening report for the proposed Ballycommon Bridge to Kilbeggan Harbour Greenway, hereafter referred to as the proposed development. The proposed development relates to the provision of a Greenway Walking and Cycling route which deviates between the western and eastern towpaths of the Kilbeggan Branch of the Grand Canal, from Ballycommon Bridge in County Offaly, northwards to Kilbeggan Harbour, Co. Westmeath. For the purposes of this Part 8 consent process, the proposed project relates to the development of a greenway along the former Kilbeggan Branch Canal for a distance of c.13.5km in total. This EIA screening report contains necessary information to enable the competent authority, in this case Offaly and Westmeath County Councils, to undertake an EIA screening assessment and determine whether an EIA is required to support the proposed development. The findings of the EIA screening assessment are presented in this report and will inform the determination by each local authority in advance of the Part 8 planning consent process. 1.2 Legislative Background EIA requirements derive from EU Directive 85/337/EEC (as amended by Directive 97/11/EC, Directive 2014/52/EU and S.I. 454 of 2011; S.I. 464 of 2011; S.I. 456 of 2011 and S.I. No 296 of 2018).) http://www.irishstatutebook.ie/eli/2018/si/296/made/en/pdf on the assessment of the effects of certain public and private projects on the environment. The purpose of this Environmental Impact Assessment Screening Report is to determine whether this proposed development will require full Environmental Impact Assessment. The Directive outlines in Article 4 (1) 21 Annex 1 projects that require mandatory EIA. Article 4 (2) outlines Annex 2 projects that require consideration for EIA further to a case by case examination or through thresholds and criteria established by Member States. Projects requiring mandatory EIA are listed in Schedule 5 of the Planning and Development Regulations 2001, as amended. Where developments are under the relevant EIA threshold, planning authorities are required under Article 103 of the 2001 Regulations, as amended, to request an EIS where it considers the proposed development is likely to have a significant effect on the environment. In these cases the significant effects of the project are assessed relative to the criteria contained in Schedule 7a of the regulations, principally: • The projects characteristics • Sensitivity of the project location, and • Characterisation of potential impacts. In addition, where the development would be located on or in an area, site etc. set out in Article 103(2), the planning authority shall decide whether the development would or would not be likely to have significant effects on the environment for such site, area or land etc. the implication being that if it decides 3
that it would be likely to have significant effects on the environment, it can invoke its powers to request an EIS. Article 103(2) sites comprise the following: a) A European Site; b) An area the subject of a notice under section 16(2) (b) of the Wildlife (Amendment) Act, 2000; c) An areas designated as a Natural Heritage Area under section 18 of the Wildlife (Amendment) Act, 2000; d) Land established or recognised as a nature reserve within the meaning of section 15 or 16 of the Wildlife Act, 1976, as amended by sections 26 and 27 of the Wildlife (Amendment) Act, 2000; or e) Land designated as a refuge for flora or as a refuge for fauna under section 17 of the Wildlife Act, 1976, as amended by section 28 of the Wildlife (Amendment) Act, 2000. The proposed Greenway is located along the Kilbeggan Branch of the Grand Canal which is designated as a proposed Natural Heritage Area (site code: 002104). The Grand Canal comprises the canal channel, the canal banks and towpaths on either side of it. The Ballyduff Esker pNHA (site code: 001755), also called Murphy’s Bridge esker intersects with the Kilbeggan canal. The proposed development also falls under the EIA requirements of the Roads Act 1993 as amended by the Planning and Development Acts (2000-2011) and the Roads Act (2007) as well as regulations made under the Roads Acts, The European Communities (Environmental Impact Assessment) (Amendment) Regulations 1989-2001, and EC Directives 85/337/EC and 97/11/EC referenced above. A road within the 1993 act is defined to include: (a) any street, lane, footpath, square, court, alley or passage, (b) any bridge, viaduct, underpass, subway, tunnel, overpass, overbridge flyover, carriageway whether single or multiple, pavement or footway, (c) any weighbridge or other facility for the weighting or inspection of vehicles, toll plaza or other facility for the collection of tolls, services area, emergency, telephone, first aid post, culvert, arch, gulley, railing, fence, wall, barrier, guardrail, margin, kerb, lay-by, hard shoulder, island, pedestrian refuge, median, central reserve. Furthermore Cycleway is referred to in Section 68 of the 1993 Act as follows: (1) In this section “cycleway” means a public road or proposed pubic road reserved for the exclusive use of pedal cyclists or pedal cyclists and pedestrians. (2) (a) A road authority may construct (or otherwise provide) and maintain a cycleway. (b) Where a road authority constructs or otherwise provides a cycleway it shall by order declare either – (i) the cycleway is for the exclusive use of pedal cyclists, or (ii) that the cycleway is for the exclusive use of pedal cyclists and pedestrians. (c) any person who uses a cycleway in contravention of an order under paragraph (b) shall be guilty of an offence. 4
1.3 Screening According to European Commission Guidance (20171) “Screening has to implement the Directive’s overall aim, i.e. to determine if a Project listed in Annex II is likely to have significant effects on the environment and, therefore, be made subject to a requirement for Development Consent and an assessment, with regards to its effects on the environment. At the same time, Screening should ensure that an EIA is carried out only for those Projects for which it is thought that a significant impact on the environment is possible, thereby ensuring a more efficient use of both public and private resources. Hence, Screening has to strike the right balance between the above two objectives.” As previously stated, this may be considered a sub-threshold EIA development, as EIA is not mandatory for walking and cycling routes such as this Greenway. The key issue for the competent/consent authority in the context of the possible need for EIA of sub-threshold is whether or not such development is likely to have significant effects on the environment. Consideration of significant effect should not be determined by reference to size only. The nature and location of a project must also be taken into account. This EIA Screening Report is therefore being undertaken to determine in light of the criteria listed in Schedule 7a of the Planning and Development Regulations whether or not this proposed development will require full EIA. According to the Guidelines for Planning Authorities and An Bord Pleanála on carrying out Environmental Impact Assessment (2018): “For all sub-threshold developments listed in Schedule 5 Part 2, where no EIAR is submitted or EIA determination requested, a screening determination is required to be undertaken by the competent authority unless, on preliminary examination it can be concluded that there is no real likelihood of significant effects on the environment. This is initiated by the competent authority following the receipt of a planning application or appeal A preliminary examination is undertaken, based on professional expertise and experience, and having regard to the ‘Source – Pathway – Target’ model, where appropriate. The examination should have regard to the criteria set out in Schedule 7 to the 2001 Regulations. Where, based on a preliminary examination of the information submitted with the application and any other supplementary information received, the competent authority concludes that, having considered the nature, size and location of the proposed development, there is no real likelihood of significant effects on the environment, this should be recorded with reasons for this conclusion stated, and no EIA required or formal determination made. The recording of the competent authority’s view should be brief and concise, but adequate to inform the public. In many cases this considered view will be included in the planner’s/inspector’s report on the planning application 1Environmental Impact Assessment of Projects Guidance on Screening (Directive 2011/92/EU as amended by 2014/52/EU). European Commission 2017. Page 23. 5
and this may be cross-referenced in the competent authority’s decision. Normally, this will be published at the time of the decision of the competent authority.” 1.3.1 Changes to the EIA Screening process. The EIA Directive (2014/52/EU) has brought a number of changes to the EIA process with a strengthening of the Screening process as follows: • Article 4 (4) of this Directive introduces a new Annex IIA to be used in the case of a request for a screening determination for Annex II projects. This is information to be provided by the developer on the projects listed in Annex II (see below): 1.3.2 Annex IIA: Information to be provided by the developer on the projects listed in Annex II. 1. A description of the project, including in particular: (a) a description of the physical characteristics of the whole project and, where relevant, of demolition works (Section 2 of this report); (b) a description of the location of the project, with particular regard to the environmental sensitivity of geographical areas likely to be affected (Section 3 of this report) 2. A description of the aspects of the environment likely to be significantly affected by the project (Section 3 of this report) 3. A description of any likely significant effects, to the extent of the information available on such effects, of the project on the environment resulting from: (a) the expected residues and emissions and the production of waste, where relevant (Section 4 of this report) ; (b) the use of natural resources, in particular soil, land, water and biodiversity (Section 4 of this report). 4. The criteria of Annex III shall be taken into account, where relevant, when compiling the information in accordance with points 1 to 3 (Section 4 of this report). Article 4(4) specifies that the developer may provide a description of any features of the project and/or mitigation measures to avoid or prevent what might otherwise have been significant effects on the environment. It should be noted that this does NOT include compensation measures (Mitigation measures are provided in Section 2.2.). 1.3.3 Article 4(5) Determination of Screening The competent authority shall make its determination, on the basis of information provided by the developer in accordance with paragraph 4 taking into account, where relevant, the results of preliminary verifications or assessments of the effects on the environment carried out pursuant to Union legislation other than this Directive. The determination shall be made available to the public and: (a) where it is decided that an environmental impact assessment is required, state the main reasons for requiring such assessment with reference to the relevant criteria listed in Annex III; or 6
(b) where it is decided that an environmental impact assessment is not required, state the main reasons for not requiring such assessment with reference to the relevant criteria listed in Annex III, and, where proposed by the developer, state any features of the project and/or measures envisaged to avoid or prevent what might otherwise have been significant adverse effects on the environment. The EIA Screening prepared here will inform the competent authority, in this instance Westmeath and Offaly County Councils on the EIA Screening Determination please see Section 5 of this Report for the EIA Screening Determination as proposed. 1.4 Approach to this EIS Screening This EIS Screening report has been prepared and informed by the following guidance and guidelines: • Guidelines for Planning Authorities and An Bord Pleanála on carrying out Environmental Impact Assessment, Department of Housing, Planning and Local Government, 2018; • Environmental Impact Assessment of Projects Guidance on Screening (Directive 2011/92/EU as amended by 2014/52/EU), European Commission, 2017. • Environmental Impact Assessment (EIA) Guidance for Consent Authorities regarding Sub- threshold Development, Department of Environment, Heritage and Local Government, 2003; • Guidance on the Information to be contained in Environmental Impact Statements Environmental Protection Agency 2002, and • Environmental Impact Assessment (Agriculture) Regulations 2011 Guide for Farmers, Department of Agriculture, Food and the Marine,2011) A desktop study of environmental receptors within the project area was undertaken in addition to a site walkover by the project ecologist Pat Doherty MSc, MCIEEM in July and August 2018. A review was also undertaken of relevant projects within the project area. The screening for Appropriate Assessment that was prepared as part of the current application has informed this EIA Screening report. 1.5 Statement of Authority This report has been prepared by Ruth Minogue, MCIEEM. Ruth has been a practicing environmental consultant for 20 years and has specialised in the preparation of Environmental Impact Assessment and Strategic Environmental Assessment. Additional inputs were provided by Pat Doherty, MCIEEM, an ecologist with 17 years practical experience and Dr. Ronan Hennessey, who provided the Geographical Information Systems analysis and mapping outputs. 7
2 Description of the Proposed Development 2.1. Description of Proposed development The proposed project relates to the development of a greenway along the former Kilbeggan Branch Canal of the Grand Canal for a distance of c.13.5 kilometres connecting Ballycommon Bridge in Co. Offaly with Kilbeggan Harbour, Co. Westmeath. This part of The Grand Canal (Kilbeggan Branch), which was constructed between 1830-36 was officially closed in 1961, but has been out of use since the end of the nineteenth century due to the development of road and rail transportation networks. It continues to provide an attractive environmental amenity route along an established dried out canal. The landscape associated with this greenway is varied, encompassing boglands, esker, woodlands and grasslands along this route. The proposed greenway encompasses predominantly lowlying, flat land and in this regard, its gradient is conducive to all users (including the cyclist, walker, person in a wheelchair and person pushing a buggy) without compromising on the scenic qualities of this route. The design of this project incorporates surfacing which will be finished to a high specification in accordance with required standards, so as to market and attract both the domestic and international tourist to this greenway, as well as accommodating the local communities within its vicinity for recreational purposes. 2.1.2 Features of the proposed development The proposed Kilbeggan-Ballycommon Greenway will include the following features: c.13.5 km of shared walking and cycling Greenway along the existing towpath. • Path widths will vary along the greenway from 1.5m to 3m at its widest. Widths will be dictated by existing on-site features. • Improvements to the existing towpath along the former canal through the provision of suitable surfacing including 804 sub-base and Quarry Dust which will be the primary surface; surface dressing/Asphalt Tarmac (to be utilised where deemed necessary and appropriate for vehicular access (serving necessary agricultural use/ Waterways Ireland operations only) and other material finishes will be incorporated into the scheme where appropriate. • Provision of access controls such as pedestrian and cycle friendly gates along the route. • The provision of a temporary construction compound to be situated at the works yard in Kilbeggan and close to Ballycommon Bridge. All associated ancillary works and integrated landscape plans for the reinstatement of temporary construction footprint. The detailed approach to the works to the Greenway is presented in the following section but primarily comprise the following: • Upgrading of former towpath (deviating between eastern and western side of proposed greenway in accordance with design of route proposed) with varying surfaces proposed having regard to sensitivities and constraints (visual, environmental, physical) of the greenway. • Traffic safety measures to facilitate safe pedestrian and cycling crossings. 8
• Fencing/gates to facilitate safety and permit access to agricultural lands, where required. • There is no lighting proposed as part of this application. • Tree removal is not proposed other than pruning of overhanging branches or limited removal where necessary to meet minimum greenway width. 2.1.3 Habitat loss to the footprint of the development A worst-case scenario calculation was made to estimate habitats to be lost to the footprint of the development. The methodology employed utilised the shapefiles provided by Waterways Ireland from the 2013 Ecology Survey, overlaid with the drawings provided by the two local authorities. The calculations below assume a total footprint of 3m for the whole Greenway by calculating habitat loss of 1.5 m from the centre of the existing towpath. It is to be noted however that the footpath will reduce to 1.5m/2m at key areas, where due to a number of considerations (including ecological considerations, physical constraints and/or visual sensitivities in ensuring the assimilation of the greenway into its surroundings), a narrower footprint is required. In addition, replacement and enhancement measures are provided in Section 2.10 to compensate for loss of important habitats and recreate in particular conditions that will encourage reestablishment and growth of calcareous grasslands over time.

2.2 Methodology for Greenway Construction 2.2.1 General Methodology: As outlined in the introduction, the proposal is to develop a greenway (cycleway and footway) upon the towpath (deviating between eastern and western side towpath) of the former Kilbeggan Branch of the Grand Canal from Kilbeggan Harbour to Ballycommon Bridge. Works will be completed and overseen by the respective local authorities i.e. Westmeath County Council and Offaly County Council and will include a subcontractor agreement with a qualified Ecological Clerk of Works.(See section 2.11)). 2.2.2 Equipment The following will be used in the work, where necessary. Tracked Excavator Mini Excavator Hand/Power Tools Barriers Signage JCB Excavator Trucks Grader Tractor mounted hedge cutter. 2.2.3 Surface Water Management Surface water runoff during the construction phase will be contained (and will either drain to ground or will drain away from the canal). Water will be prevented from draining to the canal through the retention of the existing bank on the canal side of the towpath and where this is absent, the provision of a barrier at such locations that will prevent the migration of surface water to the canal. 2.2.4 Noise and Vibration Noise and vibration emissions will be generated during the construction phase. In order to minimise any potential for noise and vibration and potential nuisance to residents located within proximity to the canal and other ecological receptors such as otters or badgers mitigation measures will be implemented. These measures will adhere to the best practice guidelines outlined in BS5228: Code of Practice for Noise and Vibration Control on Construction and Open Sites – Part 1 Noise (2009 + A1 2014). These standard guidelines offer detailed guidelines on the control of noise and vibration from construction activities. The following mitigation measures will be implemented during the construction phase of the proposed development to ensure noise and vibration limit values are complied with: • The hours during which site activities are likely to create high levels of noise will be limited to a set time period; • A site representative will be appointed to take responsibility of all matters relating to noise and vibration; • Plant with low inherent potential for generating noise and/or vibration will be selected for construction; • Where required, noise barriers will be erected around items such as generators or high duty compressors; 13
• Plant which have high inherent potential for generating noise will be sited as far away from sensitive properties as permitted by site constraints. With the implementation of the measures it is predicted that the nuisance impact of noise generated during the construction phase will be of a short-term, slight, negative nature. 2.2.5 Construction sequence Prior to the commencement of the construction works, the setting out of the construction footprint along the proposed greenway will be the first item of works to be completed on the ground. The construction footprint will be limited to the width of the existing towpath where present (as indicated on drawings) from its boundary adjacent to the bankside verge to its boundary which is represented variously by a grassy verge, treelines, hedgerows. In the case of the expanse of bogland and woodland areas which the greenway will traverse, the construction corridor will be limited to encompassing lands of the greenway and necessary construction corridor. Once marked out on the ground the construction corridor temporary fencing will be installed. Once fencing is in place all construction plant, machinery and personnel will be restricted from encroaching into areas along the canal beyond the temporary construction fenceline. Once the fenceline is in place, the subject lands will be closed to the public for the duration of the construction phase. 2.2.6 Ecologically Sensitive Areas. 7 such areas are identified along the Kilbeggan Branch and these will be marked out as part of the initial construction sequence, prior to commencement of construction works. Please see table within Section 3.3.3 for further details. 2.2.7 Surface Types Tailored surface finishes shall be employed to ensure a durable and fit for purpose greenway in accordance with National Trails Office Guidance. These surfaces will not only improve accessibility but provide a more robust surface that will be able to withstand increased footfall. Surface dressing will also be utilised where deemed necessary and appropriate for vehicular access (serving necessary agricultural use/ Waterways Ireland operations only) and other material finishes will be incorporated into the scheme where appropriate. 2.2.8 Construction Methodology for Surface Types 804 and Quarry Dust: Geotextile Polybrane 240 Membrane or alternative equivalent product grade Sub -Base layer 4” Down Broken Stone, then Granular sub-base, in accordance with Clause 804 of Tii Specification. Any Stripped vegetation and excavated topsoil to be stacked neatly either side of formation tray to be used for reinstatement of path shoulders. 14
There will be no excavation requirements in regard to the overlay of the existing surface other than to address isolated issues with soft spots. Surface Layer Surface layer 0/6mm crushed limestone or quarry dust. Using either a drag box or suitable excavator lay limestone dust to falls and levels, to form 1.5m to 3m wide path surface. Compact surface layer using a roller until satisfactory compaction is achieved. Once rolling is finished, check levels of the surface at regular intervals along the compacted surface layer for consistent even surface regularity. Any part of the surface layer deviating from the required level must be raked off or topped up with additional limestone dust and re- compacted to the correct levels. Surface Dressing / Bitmac/Asphalt Geotextile Polybrane 240 Membrane or alternative equivalent product grade . Sub -Base layer 4” Down Broken Stone then Granular sub-base, in accordance with Clause 804 of Tii Specification. Base layer 60mm Dense Bitumen Macadam base course to NRA Specification for Road Works (Series 900). Surface layer 40mm hot rolled asphalt to NRA Specification for Road Works (Series 900) or Dense Bitumen Macadam wearing course to NRA Specification for Road Works (Series 900). Landscaping Using available topsoil and turfs from excavations (and only if necessary, imported topsoil). Landscaped verges and edges should be finished level with path surface and taper down and away from the path surface to allow surface water to run off onto adjacent verges. Other Surfacing Other surface finishes (including geotextile installation) may be incorporated into the project, where appropriate. 15
2.3 Best Practice Construction Approach All construction works, relating to the activities and construction sequence outlined in Section 2.2 above, will be undertaken in accordance with the following: o Inland Fisheries Ireland’s Requirements for the Protection of Fisheries Habitat during Construction and Development Works. o CIRIA (Construction Industry Research and Information Association) Guidance Documents ▪ Control of water pollution from construction sites (C532) ▪ Control of water pollution from linear construction projects: Technical Guidance (C648) ▪ Control of water pollution from linear construction projects: Site Guide (C649) ▪ Environmental Good Practice on Site (C692) o NRA Guidance Documents ▪ Guidelines for the Crossing of Watercourses during the Construction of National Road Schemes ▪ Guidelines for the Management of Noxious Weeds and Non-Native Invasive Plant Species on National Roads ▪ Guidelines for the Protection and Preservation of Trees, Hedgerows and Scrub Prior to, during and Post Construction of National Road Schemes. All work completed to be in compliance with the Wildlife Acts, 1976 – 2012; In areas where Annex II-listed species (e.g. Badgers) or Flora Protection Order species are known to occur the works shall be carried out under licence from the NPWS. 2.4 Pre-Construction Prior to construction commencing, Westmeath and Offaly County Councils will record sensitive areas highlighted in either the statutory conditions and/or conditions on the ground, giving particular reference to the site operational issues also listed below. This will include the areas identified as Ecological Sensitive Areas identified by the 2013 Survey, and areas within the footprint of the towpath or adjacent to the proposed greenway route identified through the habitat mapping produced as part of these surveys. The identification of these areas on the ground and supervision of fencing off will be supervised by an Ecological Clerk of Works, to be appointed by the Local Authority. 16
2.5 Earthworks • Excavation and infilling will be carried out in small progressive stages; • Any topsoil that is of use for landscaping will be stored on the site. Where this is required during the construction phase, it will be stored suitably far away from surface water features and covered to avoid excessive sediment run-off or wind blow; • Whilst no significant run-off of silt laden run-off is anticipated, given the proposed construction methodology, the site will be regularly monitored by construction staff for signs of run-off such as silt in surrounding vegetation and measures will be put in place to prevent this where necessary. This may include the provision of a solid containment berm (of soil) or alternatively the erection of a silt fence. A silt fence may be constructed by attaching a sheet of geotextile membrane to a stock fence and burying the bottom of it into the ground, thus allowing water to pass through but not the heavier fraction of the sediment; • Excavations will be carried out using a suitably sized excavator; • Any excavated soil that is not re-used will be disposed of to a Local Authority approved waste disposal facility; • In all circumstances, excavation depths and volumes will be minimised and excavated material will be re-used where possible. 2.6 Fuel Use and Storage The use of machinery at the site carries the potential for accidental hydrocarbon contamination of the area, by fuel spillages or oil leaks for example. The works will be carried out in accordance with the following measures to avoid such impacts: • Mobile storage such as fuel bowsers will be bunded to 110% capacity to prevent spills. Tanks for bowsers and generators shall be double skinned. • When not in use, all valves and fuel trigger guns from fuel storage containers will be locked. • All plant refuelling will take place on site using mobile fuel bowsers. Only dedicated trained and competent personnel will carry out refuelling operations. 17
• Plant refuelling will take place as far as practicable from watercourses located within proximity such as the Silver River and Grand Canal at Ballycommon. A spill kit and drip tray shall be on site at all times and available for all refuelling operations. Equipment shall not be left unattended during refuelling. • All pipework from containers to pump nozzles will have anti siphon valves fitted. • Strict procedures for plant inspection, maintenance and repairs shall be detailed in the contractor’s method statements and machinery shall be checked for leaks before arrival on site. • All site plant will be inspected at the beginning of each day prior to use. • Defective plant shall not be used until the defect is satisfactorily fixed. • All major repair and maintenance operations will take place off site. • Care will be taken at all times to avoid contamination of the environment with contaminants other than hydrocarbons, such as uncured concrete or other chemicals. • The plant refuelling procedures described above shall be detailed in the contractor’s method statements. 2.7 Measures to Protect Water Quality & Surface Water Bodies • A number of aqueducts (five in total) occur along the proposed Greenway Route. These aqueducts cross over watercourses such as the Silver River. To prevent the ingress of any surface water or dust emissions to these watercourses during the construction phase, a temporary silt trap and impermeable barrier will be placed along the edge of the aqueduct while dust screens will be placed over the aqueduct guardrails. • Suitable prevention measures will be put in place at all times to prevent the release of sediment to other drainage channels associated with construction areas and migration to adjacent watercourses. • To reduce erosion and silt-laden runoff, the creation, where possible, of natural vegetation buffers between the construction footprint and the canal area and other drainage channels and divert runoff from exposed excavated areas will be undertaken. • Disturbance to natural drainage features will be avoided during the construction and/or maintenance of proposed greenway. • Excavated material will not be stored immediately adjacent to watercourses. • During maintenance works of greenway, no construction activities will be undertaken at watercourse crossing in wet weather conditions. 18
• Any refuelling or lubrication of machinery will not be undertaken within 50m of a watercourse. 2.8 Non-Native Invasive Species The presence of non-native invasive terrestrial plant species was not identified along the proposed Greenway Route during the 2013 habitat surveys. However, Canadian waterweed was recorded in the 2013 survey in an area south of Wood of O Bridge (Offaly County Council). • The proposed works will involve the movement of soil on the site and will create disturbed ground that may, in the absence of undertaking biosecurity measures at construction stage, be subject to colonization with non-native and invasive species such as Japanese Knotweed and Butterfly Bush. In this regard, the following biosecurity measures to be undertaken:Any vegetation clearance or construction works to be undertaken in the vicinity of areas identified as supporting non-native species will be undertaken in accordance with the Transport Infrastructure Ireland (TII) (formerly the National Roads Authority (NRA)) guidance measures for the control and management of noxious weeds and non-native invasive species (see NRA, 2010). Sites of known infestation shall be clearly marked prior to works and avoided during construction. The importance of preventing the spread of these species will form part of a tool box talk to all personnel prior to construction commencing. • In the event that additional topsoil and quarried stone is required on the site, it will be sourced from a stock that has been screened for the presence of any invasive species and where it is confirmed that none are present. • Sites of known infestation shall be clearly marked prior to works and avoided during construction. The importance of preventing the spread of these species will form part of a tool box talk to all personnel prior to construction stage. • All contractors should incorporate strict biosecurity protocols into their Construction Environmental Management Plans. These protocols to include the thorough cleaning and disinfection of all machinery prior to arrival and departure from the site, to prevent the spread of invasive species. 2.9 Mitigation Measures 2.9.1 Mitigation by avoidance The proposed greenway design has been underpinned by the mitigation hierarchy of avoidance, reduction and remediation. As such the final design of the greenway has been restricted to the footprint 19
of the former towpath (combination of eastern and western side of former canal as per accompanying drawings) and will be minimised to 1.5m to 2m width in areas of greatest sensitivity. 2.9.1.1 Habitats The proposed greenway will not involve any new watercourse crossings and only existing crossings over the Silver River and other watercourses will be utilised for the project. The absence of any new crossings will ensure potential habitat loss and disturbance to fauna along the former canal is avoided. The Ecological Clerk of Works will be employed to supervise pre-construction works, excavator works, and reinstatement works. Where soil that includes potential calcareous grassland is removed, its supervision including reinstatement works will also be supervised by the Ecological Clerk of Works. 2.9.1.2 Fauna It is not proposed to include any public lighting along the greenway. The avoidance of lighting will ensure that potential adverse effects to light sensitive species, such as bats, badgers, otters, barn owl and a range of invertebrates will be avoided. 2.9.1.3 Birds Impacts to breeding birds will be avoided by retaining trees, scrub and woodland occurring either side of the greenway. Should pruning or cutting be required to facilitate construction works or allow for the provision of minimum required greenway width, any such works will be undertaken outside of the bird nesting season and in compliance with the Wildlife Acts as amended. General Pre-Construction Badger Survey Prior to any works being carried out, a pre-construction badger survey will be undertaken in the area around Whelan’s Bridge where an active badger sett in the canal channel was identified in 2013. This survey should be completed well in advance of the commencement of construction to allow for derogation licence applications in the event that additional badger setts are identified. Should additional setts be identified adjacent to the construction footprint then all measures in line with good practice will be required to be implemented. 2.10 Enhancement Any stripped topsoil from the species rich grassland areas should be stockpiled, covered and stored (outside species-rich areas, ESAs, areas prone to flooding or areas with tall herb vegetation). This topsoil will contain a species-rich seed bank and should be utilised, where possible, as backfill or landscaping material and allowed to regenerate naturally. The identification of the most appropriate areas and supervision of same will be the responsibility of the Ecological Clerk of Works. Calcareous grassland that may be lost due to the project works may also form part of a translocation strategy to adjacent unaffected areas of grassland, elsewhere along the route with similar conditions (such as aspect). Training will be provided to local operatives in explaining the ecological importance of habitats and the implementation of a more relaxed mowing regime for ecological areas supporting calcareous grasslands, 20
where required. This will be organised by Westmeath County Council in conjunction with Waterways Ireland. 2.11 Ecological Clerk of Works It will be a requirement of the contractor to provide for an Ecological Clerk of Works to supervise works at key stages of the project, in particular in relation to excavation activities. The ecological clerk of works must be fully qualified and experienced with proof of qualifications and previous project experience and be a member of the Institute of Ecology and Environmental Management. 2.12 Monitoring Monitoring plans (during and post construction) for protected species such as bats and Otter will be implemented, where required, to ensure adverse environmental effects are avoided. Post construction monitoring of calcareous grassland will be undertaken in 2, 4 and 6 years post construction. This will form part of the planning consent. 21
3 Receiving Environment 3.1 Introduction Schedule 6 of the Planning and Development Regulations, 2001, as amended, outline the aspects of the environment likely to be significantly affected by a proposed development. These are: • Human beings • Fauna and flora • Soil • Water • Air/climatic factors • Landscape • Cultural heritage, including the architectural and archaeological heritage and cultural heritage • Material assets • The inter-relationship between the above factors. 3.1.1 Overview The Grand Canal main line comprises of some 144km extending from Dublin city and connecting with the River Shannon on the Offaly/Galway boundary. It was fully constructed in 1803, whilst the Kilbeggan Branch became operational in 1836. Closed formally to navigation in 1961 the Kilbeggan branch was seeping water from the canal banks, leading to pressure on water levels on the main line. Consequently, the Kilbeggan branch was dammed at Ballycommon, immediately upstream of Campbells Bridge and allowed to dry out. Since its closure, the canal channel has infilled with reed vegetation, scrub and wet woodland whilst in some parts the towpath margins have been reclaimed for pasture. In recent years, parts of the towpath have become popular for amenity use including walking and horseriding. The Grand Canal is a focus for a wide range of uses, especially for recreation and tourism purposes. The visual quality of the surrounding areas is intrinsic to maintaining the attractiveness of the Grand Canal corridor. As an ecological corridor, the Grand Canal is of great significance as it links and connects with a number of habitats and key watercourses along an east-west orientation. It functions as an important stepping stone for a range of species. A summary of each of the above topics as they relate to the receiving environment is provided below and each summary description is from the southern area of the former Kilbeggan Branch canal at Ballycommon northwards to Kilbeggan. 22
3.2 Human Beings The project area is located within four Electoral Districts. The immediate area is primarily agricultural with a dispersed settlement pattern of housing. The largest settlements close to the canal are Kilbeggan to the north and Tullamore to the south. Table 4 below shows the breakdown for the four relevant Electoral Districts.
