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 Maine 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 Maine 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 Maine arterial drainage scheme. It assesses the likely significant effects on Natura 2000 sites within the zone of influence of the proposed drainage maintenance activities. This report is 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 Maine 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 Maine 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 Maine 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 Maine 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 Maine Arterial Drainage Scheme The Maine Arterial Drainage Scheme is located in Co. Kerry. It includes 261km of watercourse and 95.7km of embankment. Figure 2-1: Map of the Maine Scheme

3 Surface Water Pathways

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

3.2 Results for the Maine Scheme

3.2.1 Level 1: Characterisation and Initial Impact Assessment It is assumed that none of the proposed drainage maintenance activities in the Maine 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 Maine Arterial Drainage Scheme. Step 2 There are two Natura 2000 sites within the same surface water catchment and sub-catchments overlapped by the Maine Arterial Drainage Scheme, as detailed in Table 3-1. Of these both were identified as having surface water connectivity with the Scheme. Table 3-1: Surface Water Pathway - Step 2 Is site within the same Is there surface water Natura 2000 Site (Site Code) surface water catchment connectivity with the as the scheme? scheme? Castlemaine Harbour SAC (000343) Yes Yes Castlemaine Harbour SPA (004029) Yes Yes

Two Natura 2000 sites remain within the screening assessment. Step 3 The Qualifying Interests/Special Conservation Interests for the remaining two 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 two 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? Castlemaine Harbour SAC (000343) Yes Castlemaine Harbour SPA (004029) Yes

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 Maine Arterial Drainage Scheme was identified, as detailed in Table 3-3.

3.2.3 Level 3: Potential Impact and Significance Assessment Step 5 This stage determines whether there is potential for the 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.

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.

Note: * proceeding under the precautionary principle as no pressure or threats with a complete source-pathway- receptor chain via land or air were identified,

2014s1164 AA Screening Maine v2.0 8

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. Table 3-6: Surface Water Pathway - Steps 7 and 8 for SACs

Step 9 A review of the attributes and targets for the SWD Qualifying Interests/Special Conservation Interests has identified that there is potential for significant effects on Qualifying Interests/Special Conservation Interests in the following Natura 2000 sites. Table 3-8: Surface Water Pathway - Step 9 Potential for Effects Based Potential for Likely Natura 2000 Site on Attributes Significant Effects Castlemaine Harbour SAC Yes Yes (000343) Castlemaine Harbour SPA Yes Yes (004029)

Step 10 In conclusion, the above steps have determined that the following Natura 2000 sites will require a Stage 2 Appropriate Assessment to be undertaken and the preparation of a Natura Impact Statement. However, if more data becomes available, further site specific investigations can be undertaken and this screening conclusion re-assessed.

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 Maine Arterial Drainage Scheme. The impacts of these pathways, if any, on Natura 2000 sites are then assessed.

4.2 Results for the Maine Scheme

4.2.1 Level 1: Characterisation and Initial Impact Assessment It is assumed that none of the proposed drainage maintenance activities in the Maine 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 Maine Arterial Drainage Scheme. Step 2 There are two Natura 2000 sites within 0.01km and two Natura 2000 sites located within 0.6km of the Scheme, as detailed in Table 4-1. Table 4-1: Land & Air Pathway - Step 2 Natura 2000 Site Name 0.6km Buffer Zone 0.01km (Overlap) (Site Code) Indirect impacts for noise and Direct impacts from physical Type of Impact visual disturbance through air disturbance of habitats pathways through land pathways Castlemaine Harbour SAC Yes Yes (000343) Castlemaine Harbour SPA Yes Yes (004029)

Step 3 The Qualifying Interests/Special Conservation Interests for each Natura 2000 site were obtained from the relevant Conservation Objective document available from the NPWS (2014). Table 4-2 below details which of the two Natura 2000 sites identified in Table 4-1 above have Qualifying Interests/Special Conservation Interests which can be potentially impacted upon by land and air pathways.

Step 6 Relevant information relating to each Natura 2000 site, 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 4-4.

Step 7 Not applicable to this pathway. Step 8 As part of this step, further information on the following sites was collected to determine the location of drainage maintenance activities relative to the Qualifying Interests/Special Conservation Interests of each site, to determine if they are located in or outside of the zone of influence:  Castlemaine Harbour SAC (000343) – The Conservation Objective Supporting Documents for marine and coastal habitats in the SAC (NPWS, 2011a and 2011b) provide further detail on where the different Annex I habitats and Annex II species can be found. The marine habitats of estuaries, and also mudflats and sandflats exposed at low tide dominate the open water areas of the harbour (see Figure 4-1 and Figure 4-2) and therefore come into close proximity with scheme watercourses. The coastal habitats cover smaller areas of the SAC, within specific areas of particular interest. For example, the Inch Spit is important for a range of dune habitats, saltmarsh (including areas of Salicornia) and Spartina swards; the Rosbehy area is an important saltmarsh; and the Cromane area also consists of saltmarsh. However, these areas are in the middle and outer estuary, more than 2km from the nearest scheme watercourse. However, NPWS (2011a) do identify some areas of Atlantic salt meadows, Mediterranean salt meadows and Spartina swards in areas where scheme watercourses are present (i.e. east of Cromane, Whitegate. Fybagh) (see Figure 4-3 as an example). There is limited information available on species distribution within the SAC, although Petalwort is associated with dune slack habitats on the Inch Spit (NPWS, 2011a).

 Castlemaine Harbour SPA (004029) -– The Conservation Objective Supporting Document (NPWS, 2011c) for the SPA provides information on bird distribution and occurrence throughout the harbour. This is done from 2009/2010 Waterbird Survey Programme which divides the estuary into a number of subsites. Subsites OK456, OK458, OK466, OK455, OK457, OK467, OK449 and OK468 contain, or are immediately adjacent to, watercourses where drainage maintenance works are proposed. Bird species recorded in these subsites include Light-bellied Brent Goose, Wigeon, Ringed Plover, Sanderling, Bar-tailed Godwit, Mallard, Scaup, Comorant, Oystercatcher, Greenshank, Redshank and Turnstone. The areas near where drainage maintenance works are proposed do support Pintail, Common Scoter or Red-throated Diver.

Where no information on the location of Qualifying Interests/Special Conservation Interests was available, the precautionary principle was applied and the Qualifying Interests/Special Conservation Interests were screened in, given their unknown location. The results are given in Table 4-5 below.

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 Maine Arterial Drainage Scheme. The impact of these pathways, if any, on Natura 2000 sites, is then assessed.

5.2 Results for the Maine Scheme

5.2.1 Level 1: Characterisation and Initial Impact Assessment It is assumed that none of the proposed drainage maintenance activities in the Maine 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 Maine Arterial Drainage Scheme. Step 2 The Maine Arterial Drainage Scheme is located across three groundwater bodies (GWB). All GWBs remain in the assessment as they all contain any Natura 2000 sites. There are 8 Natura 2000 sites (5 SACs and 3 SPAs) located within the 3 GWBs and remain within the screening assessment, as detailed in Table 5-1. Table 5-1: Groundwater Pathway - Step 2 GWB name (EU_Code) and Natura 2000 Site Natura 2000 Site (Site Code) flow regime within GWB Slieve Mish Mountains SAC (002185) Yes Dingle (IE_SW_G_033) Dingle Peninsula SPA (004153) Yes Poorly productive bedrock Mount Brandon SAC (000375) Yes Castlemaine Harbour SAC (000343) Yes Castlemaine (IE_SW_G_026) Castlemaine Harbour SPA (004029) Yes Karstic Castlemaine Harbour SAC (000343) Yes Lough Yganavan And Lough Yes Nambrackdarrig SAC (000370) KillarneyTown_1 Killarney National Park, (IE_SW_G_043) Macgillycuddy'S Reeks And Caragh Yes River Catchment SAC (000365) Karstic Killarney National Park SPA (004038) Yes Castlemaine Harbour SAC (000343) Yes Castlemaine Harbour SPA (004029) Yes

Step 3 The Qualifying Interests/Special Conservation Interests for each Natura 2000 site within the identified GWBs were obtained from the relevant Conservation Objective document available from the NPWS (2014). Table 5-2 below details which of the 8 Natura 2000 sites identified in Table 5-1 above have Qualifying Interests/Special Conservation Interests which can be potentially impacted upon by groundwater pathways.

2014s1164 AA Screening Maine v2.0 25

Seven of the 8 Natura 2000 sites were identified as supporting groundwater dependent (GWD) Qualifying Interests/Special Conservation Interests and therefore remain in this screening assessment, as detailed in Table 5-2. Table 5-2: Groundwater Pathway - Step 3 GWD Qualifying GWB name (EU_Code) Natura 2000 Site (Site Code) Interests/Special and flow regime Conservation Interests Slieve Mish Mountains SAC (002185) Yes Dingle (IE_SW_G_033) Dingle Peninsula SPA (004153) No Poorly productive bedrock Mount Brandon SAC (000375) Yes Castlemaine Harbour SAC (000343) Yes Castlemaine Castlemaine Harbour SPA (004029) Yes (IE_SW_G_026) Castlemaine Harbour SAC (000343) Yes Karstic Lough Yganavan And Lough Yes Nambrackdarrig SAC (000370) Killarney National Park, KillarneyTown_1 Macgillycuddy'S Reeks And Caragh Yes (IE_SW_G_043) River Catchment SAC (000365) Karstic Killarney National Park SPA (004038) Yes Castlemaine Harbour SAC (000343) Yes Castlemaine Harbour SPA (004029) Yes

5.2.2 Level 2: Existing Impact Assessment Step 4 Under the requirements of the WFD the Environmental Protection Agency (EPA) has classified GWBs as being ‘at risk of not achieving’, ‘possibly at risk of not achieving’, ‘expected to achieve’ and ‘strongly expected to achieve’ good water quality status. This data has been reviewed to determine the groundwater quality status of the GWBs containing Natura 2000 sites with GWD Qualifying Interests/Special Conservation Interests. The ‘At Risk’ status of these groundwater bodies is given in Table 5-3. Table 5-3: Groundwater Pathway - Step 4 GWB name (EU_Code) EPA Water Framework Natura 2000 Site (Site Code) and flow regime Directive 'At Risk' Slieve Mish Mountains SAC (002185) Probably not at risk Dingle (IE_SW_G_033) Mount Brandon SAC (000375) Probably not at risk Poorly productive bedrock Castlemaine Harbour SAC (000343) Probably not at risk Castlemaine Castlemaine Harbour SPA (004029) At risk (IE_SW_G_026) Castlemaine Harbour SAC (000343) At risk Karstic Lough Yganavan And Lough At risk KillarneyTown_1 Nambrackdarrig SAC (000370) (IE_SW_G_043) Killarney National Park, Karstic Macgillycuddy'S Reeks And Caragh At risk River Catchment SAC (000365)

Consequently those sites in the Dingle (IE_SW_G_033) GWB (i.e. Slieve Mish Mountains SAC and Mount Brandon SAC) are screened out of the assessment. The exception to this is Castlemaine Harbour SAC which also falls within the other GWBs.

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 affect 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 6 Relevant information relating to each Natura 2000 site still remaining in the screening assessment at this stage, 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 5-5.

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.

Step 8 As part of this step, further information on the following GWBs was collected to determine the likely effects of drainage maintenance activities relative to the GWD Qualifying Interests/Special Conservation Interests of each site, based on their typology. No additional information was available in the conservation objectives supporting documents. All sites have proceeded to step 9. Step 9 A review of the attributes and targets for the Qualifying Interests/Special Conservation Interests has identified that there is potential for significant effects on GWD Qualifying Interests/Special Conservation Interests in the following Natura 2000 sites. Table 5-10: Groundwater Pathway - Step 9 Potential for Effects Based Potential for Likely Natura 2000 Site on Attributes Significant Effects Castlemaine Harbour SAC Yes Yes (000343) Castlemaine Harbour SPA Yes Yes (004029)

Step 10 The following Natura 2000 sites will require a Stage 2 Appropriate Assessment to be undertaken and the preparation of a Natura Impact Statement or further site specific investigations, if more data becomes available.
