Executive Summary JBA Consulting has been commissioned by the Office of Public Works (OPW) to provide environmental consultancy services in relation to statutory arterial drainage maintenance activities for 2014. Following the methodology outlined in the Screening Methodology Report (Ryan Hanley, 2014a), this report assesses the likely significant effects on Natura 2000 sites within the zone of influence of the proposed drainage maintenance activities in the Brosna Arterial Drainage Scheme in accordance with Article 6(3) of the Habitats Directive (Council Directive 92/43/EEC on the conservation of natural habitats and of wild fauna and flora). Three source > pathway > receptor chains have been examined to assess the likely impact of drainage maintenance activities on Natura 2000 sites; surface water, land and air, and groundwater pathways. From this screening exercise it has been determined that significant likely effects may arise on the following Natura 2000 sites as a result of OPW drainage maintenance activities in the Brosna Arterial Drainage Scheme.

1 Introduction

1.1 Background JBA Consulting has been commissioned by the Office of Public Works (OPW) to provide environmental consultancy services in relation to statutory arterial drainage maintenance activities for 2014. This report provides the results of the Appropriate Assessment Screening methodology for the Brosna arterial drainage scheme. It assesses the likely significant effects on Natura 2000 sites within the zone of influence of the proposed drainage maintenance activities in accordance with Article 6(3) of the Habitats Directive (Council Directive 92/43/EEC on the conservation of natural habitats and of wild fauna and flora).

1.2 Legislative Context The Habitats Directive (Council Directive 92/43/EEC on the conservation of natural habitats and of wild fauna and flora) aims to maintain or restore the favourable conservation status of habitats and species of community interest across Europe. The requirements of this Directive are transposed into Irish law through the European Communities (Birds and Natural Habitats) Regulations) 2011 (S.I. No. 477 of 2011). Under the Directive a network of sites of nature conservation importance have been identified by each Member State as containing specified habitats or species requiring to be maintained or returned to favourable conservation status. In Ireland the network consists of Special Areas of Conservation (SACs) and Special Protection Areas (SPAs), and also candidate sites, which form the Natura 2000 network. Article 6(3) of the Habitats Directive requires that, in relation to European designated sites (i.e. SACs and SPAs that form the Natura 2000 network), "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". A competent authority (e.g. the OPW or Local Authority) can only agree to a plan or project after having determined that it will not adversely affect the integrity of the site concerned. Under article 6(4) of the Directive, if adverse impacts are likely, and in the absence of alternative options, a plan or project must nevertheless proceed for imperative reasons of overriding public interest (IROPI), including social or economic reasons, a Member State is required to take all compensatory measures necessary to ensure the overall integrity of the Natura 2000 site. The European Commission have to be informed of any compensatory measures adopted, unless a priority habitat type or species is present and in which case an opinion from the European Commission is required beforehand (unless for human health or public safety reasons, or of benefit to the environment).

1.3 Appropriate Assessment Process Guidance on the Appropriate Assessment (AA) process was produced by the European Commission in 2002, which was subsequently developed into guidance specifically for Ireland by the Department of Environment, Heritage and Local Government (DEHLG) (2009). These guidance documents identify a staged approach to conducting an AA, as shown Figure 1-1.

2014s1164 AA Screening Brosna v2.0 1

1.3.1 Stage 1 - Screening for AA The initial, screening stage of the Appropriate Assessment is to determine: a. whether the proposed plan or project is directly connected with or necessary for the management of the European designated site for nature conservation b. if it is likely to have a significant adverse effect on the European designated site, either individually or in combination with other plans or projects For those sites where potential adverse impacts are identified, either alone or in combination with other plans or projects, further assessment is necessary to determine if the proposals will have an adverse impact on the integrity of a European designated site, in view of the sites conservation objectives (i.e. the process proceeds to Stage 2).

1.3.2 Stage 2 - AA This stage requires a more in-depth evaluation of the plan or project, and the potential direct and indirect impacts of them on the integrity and interest features of the European designated site(s), alone and in-combination with other plans and projects, taking into account the site's structure, function and conservation objectives. Where required, mitigation or avoidance measures will be suggested. 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 mitigation cannot be achieved, then alternative solutions will need to be considered (i.e. the process proceeds to Stage 3).

1.3.3 Stage 3 - Alternative Solutions Where adverse impacts on the integrity of Natura 2000 sites are identified, and mitigation cannot be satisfactorily implemented, alternative ways of achieving the objectives of the plan or project that avoid adverse impacts need to be considered. If none can be found, the process proceeds to Stage 4.

1.3.4 Stage 4 - IROPI Where adverse impacts of a plan or project on the integrity of Natura 2000 sites are identified and no alternative solutions exist, the plan will only be allowed to progress if imperative reasons of overriding public interest (IROPI) can be demonstrated. In this case compensatory measures will be required.

The process only proceeds through each of the four stages for certain plans or projects. For example, for a plan or project, not connected with management of a site, but where no likely significant impacts are identified, the process stops at stage 1. Throughout the process, the precautionary principle must be applied, so that any uncertainties do not result in adverse impacts on a site.

1.4 Methodology This screening assessment has been conducted in line with guidance produced for the OPW in 2013 (Ryan Hanley, 2013a, b and c). This methodology is based on source > pathway > receptor chain principles and involves assessing likely significant effects on Natura 2000 sites within the zone of influence of the proposed drainage maintenance in relation to three pathways: 1. Surface water 2. Land & air 3. Groundwater The screening assessment involves assessing the impacts of drainage maintenance operations within the arterial drainage scheme, and its zone of influence, in relation to each of the three pathways individually. The results of each pathway are then combined in a concluding section to identify if/where likely significant effects may arise.

Conclusion

Section 6

The screening process uses a combination of GIS analysis and qualitative assessment to identify which drainage maintenance activities, on which specific watercourses, are likely to have significant effects on the integrity of Natura 2000 sites. This screening report has been produced on currently available information, with the most up-to- date versions used. Where new, or updated, information becomes available the OPW will consider and review this screening assessment if necessary.

1.4.1 Consultation The findings of the screening assessment will be subject to consultation with the National Parks and Wildlife Service (NPWS). Inland Fisheries Ireland (IFI) will also be consulted in relation to fisheries interests within the designated sites and watercourses/embankments where drainage maintenance activities are proposed.

2 Descriptions of Proposals – The Brosna Scheme

2.1 Background Between 1945 and 1995, under the Arterial Drainage Act (1945), the OPW completed 34 Arterial Drainage Schemes on river catchments, along with five estuarine embankment schemes (over 11,500km of channel and 730km of embankments). The OPW is statutorily obligated to maintain arterial drainage channels under the 1945 Arterial Drainage Act, and since their completion, maintenance of these Arterial Drainage Schemes has been ongoing, with the majority of channels maintained every five years. However, larger channels tend to be only maintained every ten years, on average.

2.2 Drainage Maintenance Activities Arterial Drainage Maintenance includes a range of operations such as silt and vegetation management, mowing and structure maintenance, as detailed in Table 2-1, and listed as channel, embankment or structure maintenance in Table 2-2 below. It is required to retain the arterial drainage scheme design capacity. Table 2-1: OPW Drainage Maintenance Subcategories Drainage Maintenance Subcategories

Within the Brosna Arterial Drainage Scheme the exact location and type of required maintenance activity varies over time. For the purposes of this screening exercise we have therefore assumed

2014s1164 AA Screening Brosna v2.0 4

that all activities may occur on all Scheme channels, structures and embankments (i.e. following the precautionary principle). In terms of structural maintenance operations it is not currently known where and when maintenance will be required. Therefore, all bridges and associated structures on those watercourses screened into the assessment via each pathway are also screened into the assessment. The list of bridges screened in for each pathway is included in Appendix B.

2.3 The Brosna Arterial Drainage Scheme The Brosna Arterial Drainage Scheme is located between Co. Offaly and Co. Westmeath. It includes 613.2km of watercourse and 46km of embankment. Figure 2-1: Map of the Brosna Scheme

3 Surface Water Pathways

3.1 Introduction The following section identifies where surface water pathways may result in drainage maintenance activities in the Brosna Arterial Drainage Scheme having a significant effect on Natura 2000 sites.

3.2 Results for the Brosna Scheme

3.2.1 Level 1: Characterisation and Initial Impact Assessment It is assumed that none of the proposed drainage maintenance activities in the Brosna Arterial Drainage Scheme are directly necessary to the nature conservation management of Natura 2000 sites. Step 1 Each of the drainage maintenance activities detailed in Table 2-1 is proposed in the Brosna Arterial Drainage Scheme. Step 2 There are 16 Natura 2000 sites within the same surface water catchment and sub-catchments overlapped by the Brosna Arterial Drainage Scheme, as detailed in Table 3-1. Of these 10 were identified as having surface water connectivity with the Scheme.

Scheme and it was therefore concluded that these Natura 2000 sites cannot be impacted upon by maintenance activities within the Scheme via surface water pathways. Ten Natura 2000 sites remain within the screening assessment. Step 3 The Qualifying Interests/Special Conservation Interests for the remaining 10 Natura 2000 sites were obtained from the relevant Conservation Objective document available from the (NPWS) (2014). Table 3-2 below details which of the remaining 10 Natura 2000 sites have Qualifying Interests/Special Conservation Interests which can be potentially impacted upon by surface water pathways (i.e. Surface Water Dependent (SWD) Qualifying Interests/Special Conservation Interests). Table 3-2: Surface Water Pathway - Step 3 Does the site contain SWD Qualifying Natura 2000 Site Interests/Special Conservation Interests?

3.2.2 Level 2: Existing Impact Assessment Step 4 The 'At Risk' status (under the Water Framework Directive (WFD) of all surface water bodies within 5km of the Brosna Arterial Drainage Scheme was identified, as detailed in Table 3-3. Table 3-3: Surface Water Pathway - Step 4 - WFD Risk Status of Surface Water Bodies in 5km of Brosna Arterial Drainage Scheme Water Management No. of Ecological Time Period Risk Status Unit Channels Status Brosna 24 Varies Varies Not at risk Probably at Brosna 16 Varies Varies risk Brosna 287 Varies Varies At Risk

3.2.3 Level 3: Potential Impact and Significance Assessment Step 5 This stage determines whether there is potential for proposed drainage maintenance activities within a scheme to effect Natura 2000 site(s) within the surface water catchment; this is based on the hydrological setting (i.e. marine, estuarine, freshwater). This is assessed from a matrix of pre-determined distances and typologies (i.e. upstream or downstream) which define the zone of influence within which effects can potentially occur within each type of setting (Ryan Hanley, 2014a). The results of this are summarised in Table 3-4. 2014s1164 AA Screening Brosna v2.0 7

Step 6 Relevant information relating to each of the remaining Natura 2000 sites, including the Conservation Objectives Supporting Document, Site Synopsis and Natura 2000 Standard Data Form, were then reviewed to identify the potential for pressures and threats and related cumulative and in-combination effects. The results of this assessment are detailed in Table 3-5.

Steps 7 and 8 These stages involved examining the SWD Qualifying Interests/Special Conservation Interests for each of the remaining 'screened in' Natura 2000 sites to identify which may potentially be impacted upon by drainage maintenance activities. This was done using a set of pre-determined buffer zones derived for each individual habitat and species, within which effects can potentially occur (Ryan Hanley, 2014a). The location of the Natura 2000 site for these stages is also important, depending on whether it is downstream, upstream or overlaps the Scheme as this situation may allow some Qualifying Interests/Special Conservation Interests to be screened out. Information, including from the Conservation Objectives, was also reviewed to determine the location of the drainage maintenance activities relative to the SWD Qualifying Interests/Special Conservation Interests. Where no information on the location of SWD Qualifying Interests/Special Conservation Interests was available, the precautionary principle was applied and the Qualifying Interests/Special Conservation Interests were screened in. Table 3-6 summarises the results of this stage for the remaining SACs and Table 3-7 provides the results for the remaining SPAs.

4 Land and Air Pathways

4.1 Introduction The following section of this report examines the land and air pathways which may arise due to drainage maintenance activities in the Brosna Arterial Drainage Scheme. The impacts of these pathways, if any, on Natura 2000 sites is then assessed.

4.2 Results for the Brosna Scheme

4.2.1 Level 1: Characterisation and Initial Impact Assessment It is assumed that none of the proposed drainage maintenance activities in the Brosna Arterial Drainage Scheme are directly necessary to the nature conservation management of Natura 2000 sites. Step 1 Each of the drainage maintenance activities detailed in Table 2-1 is proposed in the Brosna Arterial Drainage Scheme. Step 2 There are 10 Natura 2000 sites within 0.01km and 11 Natura 2000 sites located within 0.6km of the Scheme, as detailed in Table 4-1.

5 Groundwater Pathways

5.1 Introduction The following section of this report examines the groundwater pathways which may arise due to drainage maintenance activities in the Brosna Arterial Drainage Scheme. The impact of these pathways, if any, on Natura 2000 sites, is then assessed.

5.2 Results for the Brosna Scheme

5.2.1 Level 1: Characterisation and Initial Impact Assessment It is assumed that none of the proposed drainage maintenance activities in the Brosna Arterial Drainage Scheme are directly necessary to the nature conservation management of Natura 2000 sites. Step 1 Each of the drainage maintenance activities detailed in Table 2-1 is proposed in the Brosna Arterial Drainage Scheme. Step 2 The Brosna Arterial Drainage Scheme is located across 23 groundwater bodies (GWB). Ten GWBs were removed as they did not contain any Natura 2000 sites. There are 43 Natura 2000 sites (28 SACs and 15 SPAs) located within the 13 remaining GWBs and remain within the screening assessment, as detailed in Table 5-1.

5.2.3 Level 3: Potential Impact and Significance Assessment Step 5 This stage assesses whether there is potential for a drainage maintenance activity to effect the Qualifying Interests/Special Conservation Interests of the Natura 2000 site(s) within the zone of influence of a scheme. This is determined through undertaking a visual assessment of the topographic catchment of the Natura 2000 site, combined with application of a buffer to the Natura 2000 site boundaries at a pre-established distance dependent on the flow regime of the GWB (i.e. karstic, fissured, poorly productive, intergranular) (Ryan Hanley, 2014a). Depending on this, a conclusion can then be made as to whether potential effects may occur. The results of this are summarised in Table 5-4.

Step 7 This stage involves examining each of the GWBs in turn and determining, based on the GWD Qualifying Interests/Special Conservation Interests of each Natura 2000 site, whether they are likely to be significantly affected by the drainage maintenance activates. This is based on an assessment of whether the activity is up or down gradient of a Natura 2000 site.
