1 An Bord Pleanála STRATEGIC INFRASTRUCTURE DEVELOPMENT PLANNING AND DEVELOPMENT ACTS 2000 to 2010 An Bord Pleanála Reference Number: 16.GA0004 (Local Authority: Mayo County Council) APPLICATION for approval under section 182C(1) of the Planning and Development Act, 2000, as amended, by Shell E & P Ireland Limited care of RPS Group, Fifth Floor, Block E, Iveagh Court, Harcourt Road, Dublin in accordance with plans and particulars, including an Environmental Impact Statement, as originally lodged with An Bord Pleanála on the 12 th day of February, 2009 and as described in the public notice on that date, and as altered in the Environmental Impact Statement received by An Bord Pleanála on the 31 st day of May, 2010 and further described in the public notice received by An Bord Pleanála on the 6 th day of July, PROPOSED DEVELOPMENT: Construction of the Corrib Onshore Pipeline, comprising strategic upstream gas pipeline infrastructure The proposed onshore pipeline is approximately 9.2 kilometres in length, comprising part of a longer strategic upstream pipeline system for the carrying of natural gas, and associated by-products, from the existing Corrib Gas Field to the gas terminal at Béal an Átha Buí (Bellanaboy Bridge), County Mayo, previously permitted under planning authority register reference number P03/3343 (An Bord Pleanála appeal reference number PL ). The proposed pipeline system comprises the onshore gas pipeline itself, associated services umbilicals and other essential cabling, and an outfall discharge pipeline extending from the gas terminal to a location some 12.7 kilometres offshore. The proposed pipeline extends from a landfall point in the townland of Gleann an Ghad (Glengad or Dooncarton), County Mayo, in a generally easterly direction across Sruwaddacon Bay, and across land in the vicinity of the settlement of Ros Dumhach (Rossport / Rossdoagh), before re-crossing Sruwaddacon Bay, and running east and south in the townlands of Na heachú (Aghoos) and Béal an Ghoille Theas (Bellagelly South), into the Bellanaboy Bridge Gas Terminal. It is proposed to lay the pipeline within a corridor of a general width between 40 metres and 100 metres. The permanent wayleave of the pipeline will be of between 14 metres and 20 metres width. The working width during the construction phase will typically be 40 metres. The proposed development will result in the removal from use of two number houses within the settlement of Ros Dumhach (Rossport / Rossdoagh) for the duration of operation of the pipeline. 16.GA0004 An Bord Pleanála Page 1 of 25

2 The proposed development includes an above-ground Landfall Valve Installation, including an associated surface water outfall system, located in the townland of Gleann an Ghad (Glengad or Dooncarton), and the permanent use of, and associated upgrading of, an existing access road from the L1202 public road to the site of the proposed Landfall Valve Installation. The Landfall Valve Installation is designed to limit the pressure in the onshore pipeline to 144 bar or less. The proposal also includes all associated temporary and permanent construction, site development and landscaping works, including the provision of temporary site construction compounds, and including the temporary use of the existing construction compound and internal access roads within the terminal site, and the use of existing access points from the terminal site onto the public road network, previously permitted under planning authority register reference number P03/3343 (An Bord Pleanála appeal reference number PL ). Temporary vehicular access to the pipeline corridor will be taken from the public road network, including at points where the corridor crosses public roads. The proposed development will cross public roads at four number locations three number locations in the townland of Ros Dumhach (Rossport / Rossdoagh), and one number location in the townland of Béal an Ghoille Theas (Bellagelly South). It is proposed to carry out minor road improvements at the junction of the L and L in the townland of Rossport to facilitate construction traffic. The proposal includes the importation and deposition of up to 75,000 cubic metres of peat, to be excavated from the route of the proposed onshore pipeline, into and within the existing Bord na Móna peat deposition site in the townlands of Srahmore and Attavally, Bangor-Erris, County Mayo (the Srahmore site ), previously permitted under planning authority register reference number P03/3343 (An Bord Pleanála appeal reference number PL ). The proposal includes all associated temporary and permanent site works, infrastructure, and facilities which facilitate such use of, and activity at, the Srahmore facility. The proposed activity at Srahmore comprises an activity for which a separate waste licence is required. Following a request by An Bord Pleanála to the undertaker under section 182C(5) of the Planning and Development Act 2000, as amended, to make alterations to the proposed development including modifying the pipeline route, the proposed development has been altered as described in the revised Environmental Impact Statement received by An Bord Pleanála on the 31 st day of May, 2010, as follows:- The altered pipeline extends from the High Water Mark to the landfall at Glengad townland, County Mayo in a route under Sruwaddacon Bay to Aghoos townland and to Bellagelly South townland, and into the Bellanaboy Bridge Gas Terminal The nature of the specified alterations is as follows (All placenames referred to are located in County Mayo save for Sruwaddacon Bay which is partly in County Mayo and partly in the foreshore): Modified pipeline route, to be beneath Sruwaddacon Bay (and approaches to same) between chainages and (per pipeline chainages in 2009 application) (Glengad and Aghoos). 16.GA0004 An Bord Pleanála Page 2 of 25

3 A further significant increase in separation distance between the proposed pipeline to the nearest occupied residence. The proposed pipeline is now reduced in length by 0.9 kilometres to approximately 8.3 kilometres long. The altered route under Sruwaddacon Bay (and the approaches to same) of approximately 4.9 kilometres will include the placing of the pipeline within a 4.2 metre (outside diameter) tunnel, constructed from Aghoos to Glengad. Approximately 4.6 kilometres of the tunnel will be beneath Sruwaddacon Bay. A Maximum Allowable Operating Pressure in the Onshore Pipeline (between the Landfall Valve Installation and the Bellanaboy Bridge Gas Terminal) of 100 barg. A Maximum Allowable Operating Pressure in the Offshore Pipeline (upstream of, and including, the Landfall Valve Installation) of 150 barg. The proposed pipeline is no longer located within Priority Habitat in the Glenamoy Bog Complex (candidate Special Area of Conservation). The tunnel will be constructed in one direction from Aghoos and the pipeline will be assembled and installed into the tunnel from Aghoos; as a result the tunnelling compound at Aghoos will be larger and will see an increased volume of activity while the tunnelling compound at Glengad will see a decreased level of activity, and there will be no construction activity at Rossport. The section of pipeline from chainage to the High Water Mark at Glengad has been included within the development application. Ancillary changes to the development arising out of the specified alterations are also included. These include: a spare umbilical, electrical cable, fibre optic cable and water discharge pipeline within the tunnel, increased width of the stone road by 3 metres to 12 metres, increased importation of material to the Aghoos tunnelling compound, increased volume of excavated material (approximately 68,000 cubic metres) and a longer duration of construction works. DECISION GRANT approval under section 182D of the Planning and Development Act, 2000, as amended, for the above proposed development in accordance with the said plans and particulars based on the reasons and considerations under and subject to the conditions set out below. 16.GA0004 An Bord Pleanála Page 3 of 25

Vibration monitoring shall be carried out during construction as provided in the Environmental Impact Statement generally and in the specific detail provided at oral hearing [Oral Hearing Document Reference Number 25]. The monitoring shall include: Monitoring at the Aghoos Tunnel Launch Pit Area and Monitoring at the Glengad Tunnel Reception Pit Area (a) At each site monitoring vibration from (i) Piling activity (ii) Rock Excavation activity (iii) Tunnel Boring Machine activity. In the case of the Glengad site, monitoring is to be carried out as the Tunnel Boring Machine approaches the site. (b) Monitoring at 25 metres and 50 metres from the source on two orthogonal planes aligned parallel and perpendicular to the predominant foliation or schistocity of the rock or as close to parallel and perpendicular as may be practicable. The monitoring shall serve to characterise the site specific ground response to these construction activities and shall provide verification data for review of the model predicted vibrations. An interpretative report and the data of the monitoring activity shall be provided to Mayo County Council and to the Project Monitoring Committee and published on a website in accordance with monitoring procedures established. Vibration shall not exceed the standards set out in National Roads Authority Guidelines for Treatment of Noise and Vibration in National Road Schemes so that the maximum allowable vibration velocity (PPV) at the closest part of any sensitive property (including any dwelling) to the source of vibration shall be as follows: Less than 10Hz For all vibrations >10Hz 8 mm/sec 12.5 mm/sec Reason: To provide for the control of vibrations and ensure there is no adverse impact from excavation works. 16.GA0004 An Bord Pleanála Page 17 of 25

18 31. The hazards listed on the Geotechnical Risk Register in the Environment Impact Statement submitted to An Bord Pleanála shall be the subject of ongoing monitoring throughout the development. A qualified engineer with appropriate experience shall carry out the monitoring. During the excavation and construction phase, the undertaker shall submit a report in relation to the Risk Register every two months to Mayo County Council and the Project Monitoring Committee. The report shall describe the progress of monitoring the hazards listed on the Register and shall detail any specific difficulties encountered and contingencies employed. The reports shall be made available for public inspection within seven days of submission at the offices of Mayo County Council and the offices of the undertaker in Belmullet. Reason: In the interest of safety and the proper planning and sustainable development of the area. Control of Waste 32. All tank and drum storage areas on the sites shall, as a minimum, be bunded to a volume not less than the greater of the following:- 110% of the capacity of the largest tank or drum within the bunded area, or 25% of the total volume of substances which could be stored within the bunded area. Reason: To prevent surface and ground water or surface pollution. 33. All fuel storage areas and cleaning areas, particularly for trucks, shall be rendered impervious to the stored or cleaned materials and shall be constructed to ensure no discharges will cause pollution to ground waters. Reason: To prevent surface and ground water pollution. 34. The undertaker shall maintain on the sites, for the duration of the construction period, oil abatement kits comprising of booms and absorbent materials. Reason: To prevent water pollution. 35. Prior to disposal of materials from site that have derived from tunnel arisings, testing shall be carried out on the materials to confirm appropriate waste disposal options and records of the testing shall be maintained by the undertaker. Reason: To protect the environment. 16.GA0004 An Bord Pleanála Page 18 of 25

19 Sanitary Waste Facilities and Management 36. Sanitary facilities shall be installed in the compounds and on the site of the construction works and on the site of the peat deposition area for the duration of the construction project. All waste generated from such facilities shall be disposed of by a licensed waste contractor to an appropriate approved treatment works. Reason: In the interest of public health. 37. Where liquid wastes are being disposed of at appropriate treatment works, the undertaker shall establish that there is adequate capacity at those works to take the loadings from the liquid waste. Reason: To protect fish and the aquatic environment from consequential pollution. Construction in Peatland 38. Prior to construction of the Stone Road in the peat lands, pre-construction confirmatory examination of the site by an experienced Engineer/Geologist, as provided for in the Environmental Impact Statement and Geotechnical Risk Register, shall take place. In particular, in relation to those areas identified in the qualitative assessment of relative potential for peat failure of medium potential and high potential, the following shall apply: (a) (b) The design of the proposed stone road and the design of the compound at Aghoos shall be reviewed in light of the examination of the conditions at the site at the time of construction. Side casting of peat shall be restricted as follows: (i) No side casting of peat shall take place in those areas of relative high potential for peat failure (ii) No side casting of peat shall take place at any location ahead of the completed Stone Road i.e. where side casting peat, the area on which the peat is being placed shall lag behind the area where the Stone Road is being constructed so that peat is not side cast adjacent to an open or partially backfilled excavation. (iii) No side casting of peat shall take place where the slope on the surface, or at the base of the peat, is greater than 3 degrees (iv) No side casting of peat shall take place within 25 metres from a break in slope greater than 3 degrees. 16.GA0004 An Bord Pleanála Page 19 of 25

20 Notwithstanding the above, the designer shall carry out the necessary site investigation, design and analysis to confirm that the stability of the peat repository will be acceptable at the time of construction. Specific consideration shall be given to areas where the alignment of the road is perpendicular to the slope contours, where it will not be possible to sidecast upslope from the stone road. Reason: To ensure stability of peat and to protect the environment from any peat slide damage. 39. Within the stone road, the rock fill below the trench for the gas pipeline and umbilical shall extend beyond a minimum 45 degree influence line (1 vertical:1 horizontal) from the sides of the trench at pipe invert level down to the base of the peat. Reason: To ensure stability of peat and the pipeline and to protect the environment from any peat slide damage. 40. In the construction of the pipeline, care shall be taken in those areas where the pipeline is being laid within the stone road and below the peat in the mineral soil. In those areas peat plugs shall be installed across the stone road section at either end of those sections and at centres in between not greater than 100 metres apart. Reason: To prevent the stone road and pipeline construction acting as a preferential drain in the peat. 41. (1) In the construction of the stone road, permeability barriers shall be installed where the road approaches the Leenamore River, the two streams and ditches, which shall restrict free drainage of water through the road. (2) The construction detail for the compounds regarding drainage and restoration in the peat lands shall be similar in terms of permeability restriction to that used for the stone road. Reason: To ensure that the impact of the stone road on hydrology of the peatlands is minimised. 42. Method statements for construction works in the peatlands shall be developed using conservative design values and applying conservatively the risk mitigation measures set out in the Geotechnical Risk Register of the Environmental Impact Statement, or as may be set out in any revision of the risk register following preconstruction surveys and confirmation of method of construction and during the construction of the project. All construction work in peatland shall be supervised by professional persons with adequate expertise of the geohydrology and ecology of blanket bogs and experience of construction in peatland, who shall ensure that hydraulic paths in the peat are identified, marked and reinstated 16.GA0004 An Bord Pleanála Page 20 of 25

21 satisfactorily. An experienced contractor with specific experience of construction in peat shall be engaged for the construction. Reason: To protect against peat instability and minimise the impact of the development on blanket bog habitats. Archaeology 43. Monitoring for archaeological materials or remains shall be carried out at this site in accordance with the measures outlined in the Environmental Impact Statement and as follows: (a) The undertaker shall engage the services of a suitably qualified archaeologist who shall monitor ground disturbance works associated with the development (b) If archaeological remains are found the work may be stopped pending a decision on how best to deal with the archaeology. The undertaker shall be prepared to receive advice in this regard from the Heritage and Planning Division of the Department of the Environment, Heritage and Local Government and shall facilitate the archaeologist in recording any material found. (c) The archaeologist shall submit reports of the monitoring to Mayo County Council, the Project Monitoring Committee and the Department of the Environment, Heritage and Local Government at regular intervals as determined by Mayo County Council Reason: To protect the archaeological heritage of the area and provide for the appropriate preservation of any remains that may exist within the site. The Protection of Drinking Water Sources 44. Prior to commencement of construction, the location of wells which serve as water supply sources shall be identified, in agreement with Mayo County Council, and these wells shall be monitored prior to, during and after construction. Reason: To protect existing drinking sources in the area. 45. The undertaker shall include in the Environmental Management Plan a detailed method statement for construction of surface water drainage and discharge from the construction site in the chainage to chainage area approximately, that is in the Carrowmore Lake Catchment. Surface water from the construction project shall not discharge into the Carrowmore Lake Catchment (Chainages given here refer to the 2010 chainages) Reason: To protect the Carrowmore Lake Water Supply 16.GA0004 An Bord Pleanála Page 21 of 25
