Galway 83 ii | Irish Water Natura Impact Statement – Glenamaddy Sewerage Scheme Introduction This report forms a Natura Impact Statement (NIS) for the upgrade of the existing Glenamaddy Sewerage Scheme including a new Waste Water Treatment Plant (WwTP) located at Glenamaddy, County Galway. The purpose of this NIS is to inform the Appropriate Assessment process will be completed by the relevant competent authority. Appropriate Assessment (AA) is an assessment of whether a plan or project, alone and in combination with other plans or projects, could have significant effects on a European site in view of the site’s conservation objectives. An Appropriate Assessment is a requirement of Article 6 of the EC Directive 92/43/EEC on the Conservation of Natural Habitats and of Wild Fauna and Flora (as amended) (hereafter referred to as the “Habitats Directive”). The overall aim of the Habitats Directive is to maintain or restore the “Favourable Conservation Status” of habitats and species of European Community interest. These habitats and species are listed in the Habitats Directive and also in the Birds Directive (2009/147/EC), leading to the designation of European Sites for conservation of these interests, within the Natura 2000 network. These Natura 2000 sites include both Special Areas of Conservation (SACs) under the Habitats Directive, and Special Protection Areas (SPAs) under the Birds Directive. European and national legislation places a collective obligation on Ireland and its citizens to maintain habitats and species in the Natura 2000 network at favourable conservation condition. The Government and its agencies are responsible for the implementation and enforcement of regulations (in particular Part XAB of the Planning and Development (Amendment) Act 2010 and the European Communities (Birds and Natural Habitats) Regulations, 2011 (S.I. 477) (often referred to as the Habitats Regulations) to ensure the ecological integrity of these sites. This report follows the guidance for AA published by the Environmental Protection Agency’s (EPA) ‘Note on Appropriate Assessments for the purposes of the Waste Water Discharge (Authorisation) Regulations, 2007 (S.I. No. 684 of 2007)’ (EPA, 2009); and takes account of the Department of the Environment, Heritage and Local Government’s guidelines ‘Appropriate Assessment of Plans and Projects in Ireland. Guidance for Planning Authorities’ (DoEHLG, 2010) and Circular L8/08 1 | Irish Water Natura Impact Statement – Glenamaddy Sewerage Scheme ‘Water Services Investment and Rural Water Programmes – Protection of Natural Heritage and National Monuments’ (DoEHLG, 2008). This report, and site investigation work, was completed on behalf of Irish Water by TOBIN Consulting Engineers, utilising a qualified team of scientists (ecologist and hydrogeologist), in combination with water services engineers. Legislative Context The Appropriate Assessment process (AA) is an assessment of the potential for adverse or negative effects of a plan or project, in combination with other plans or projects, on the conservation objectives of a European Site. These sites consist of Special Areas of Conservation (SACs) and Special Protection Areas (SPAs) and provide for the protection and long-term survival of Europe’s most valuable and threatened species and habitats. Council Directive 92/43/EEC of 21 May 1992 on the Conservation of Natural Habitats and of Wild Fauna and Flora - ‘The Habitats Directive’, has been transposed into Irish law by The European Community (Natural Habitats) Regulations 2011 (S.I. No. 477). The Birds Directive, Council Directive 79/409/EC on the Conservation of Wild Birds, seeks to protect birds of special importance by the designation of Special Protection Areas (SPAs) whereas the Habitats Directive does the same for habitats and other species groups with Special Areas of Conservation (SACs). The requirement of AA is outlined in Article 6(3) and 6(4) of the EU Habitats Directive. Article 6(3) of the Habitats Directive requires that: “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 2 | Irish Water Natura Impact Statement – Glenamaddy Sewerage Scheme concerned and, if appropriate, after having obtained the opinion of the general public.” Article 6(4) of the Habitats Directive requires that: “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.” If, in spite of a negative assessment of the implications for the site and in the absence of alternative solutions, a plan or project may 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 network 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. An AA should be based on best scientific knowledge and Planning Authorities should ensure that, for Stage 2 of the Appropriate Assessment in particular, ecological and hydrological expertise (if relevant) is utilised. This report details a Natura Impact Statement to inform the AA process which is finalised by the statutory authority. This NIS was informed by desk and field studies undertaken by professionals within TOBIN’s environmental services division (ecology and hydrogeology) utilising data provided by the water services engineers. 3 | Irish Water Natura Impact Statement – Glenamaddy Sewerage Scheme Relevant Guidance This report has been carried out using the following guidance: Note on Appropriate Assessments for the purposes of the Waste Water Discharge (Authorisation) Regulations, 2007 (S.I.
