A.1. Introduction Mayo Renewable Power (MRP) is proposing to construct a 48.66 MWe biomass High Efficiency CHP plant located on the former Asahi site in Killala, . CHP or Combined Heat & Power is a form of technology whereby both heat and electricity are produced to obtain the maximum energy from the input fuel. In operation, this plant will use wood chip biomass. The fuel will be supplied from a variety of sources including locally grown willow, spruce from local forestry and forestry thinnings along with imported supplies. The 48.66MWe electricity produced by the plant will be exported directly onto the National Grid and distributed throughout the country. This development will bring jobs to the northwest of Mayo, provide a much needed boost to the local economy and deliver significant carbon savings helping Ireland deliver on its renewable energy commitment. The site requires an Industrial Emissions licence in accordance with the First Schedule to the EPA Act 1992 as amended as follows: 2.1 Combustion of fuels in installation with a total rated thermal input of 50MW or more. Planning permission for the development was granted by Mayo County Council in November 2010. An Environmental Appraisal Report was submitted with the planning application, no EIS/EIAR was required, as confirmed by the planning authority in February 2014. The BAT Conclusions for Large Combustion Plants published in July 2017 are relevant to the proposed development. Other relevant BREF documents include cooling systems, storage and energy efficiency. No derogation under Section 86A(6) is being sought under this application.

A.2. The Site MRP is located on a 2.7-hectare site in the Killala Business Park (KBP). The KBP is located on the outskirts of Killala Town (2km) and just north of Ballina (8km). The site was formerly occupied by the Japanese company Asshi For inspection Synthetic purposes Fibres only. Ltd., which ceased operations in Consent of copyright owner required for any other use. 1997. The KBP comprises a total of 400 acres of land the majority of which is Greenfield with a large section of Brownfield lands located through the centre. Today there are a number of existing and planned developments located within the KBP. Existing developments include a large vacant 7000m2 warehouse building, together with much smaller commercial and office building space. Scottish and Southern Energy operate an emergency electricity generating plant in the west of the site. Approved developments on site in include 1 no. wind turbine by Killala Community Windfarm Ltd, and an ESB approved new 110KV Electrical Transformer Station Community. Currently in the planning stage, Irish Water are proposing to construct a new waste water treatment plan to a design capacity of 2,400 P.E. This is due to be completed in Q1 2020. A.3. Surroundings As described in Section A.2, the MRP site is located approximately 3 kilometres south of Killala Town and approximately 8 kilometres north of Ballina Town. The site is accessed on the eastern boundary off the R314 Regional Rd, connecting 2 National Secondary roads, the N59 to Sligo and the N26 on to .

Ballina is the nearest main urban centre with a population of 12,000 people attracting multiple major retailers. This town is a major rail freight hub, transporting containers of Coca Cola concentrate from the towns plant taking 4,000 trucks off Irish roads. Ireland West Airport (Knock) is located approximately 50 kilometres from Ballina. While the KBP itself can be considered to be an industrialised site made up of artificial surfaces, it is located in a generally rural area, surrounded by agricultural land. There are no ecological designated areas in the vicinity of the Mayo Renewable Ltd site. The activity is not carried out on any natural habitats designated in accordance with legislation, or located such that it is liable to have an adverse effect on such natural habitats.

A.4. Materials and Process Key processes taking place on site are power generation, incoming raw water treatment, wastewater treatment, and storage of ash prior to re-use/disposal off site. Mayo Renewable Power Ltd will operate using Combined Heat & Power (CHP). CHP is a form of technology whereby both heat and electricity are produced to obtain the maximum energy from the input fuel. In operation, this plant will use wood chip biomass, which constitutes the principal materials to be used in the process. The fuel will be supplied from a variety of sources including locally grown willow, spruce from local forestry and forestry thinning’s along with imported supplies. The 48.66MWe electricity produced by the plant will be exported directly onto the National Grid and distributed throughout the country. A.5. Seveso Classification The site is not an establishment for the purpose of the EC COMAH (Seveso 2) Control of Major Accident Hazards Directive (Directive 96/82/EC) as amended by Directive 2003/105/EC of the European Parliament and of the Council of 16 December 2003 because the threshold quantities of dangerous Forsubstances inspection purposes are notonly. exceeded. Consent of copyright owner required for any other use. A.6. Atmospheric Emissions The main boiler emission point from the facility is the CHP boiler stack. Vents and valves in the plant are considered minor emission points. The emission data and source characteristics for the CHP boiler stack are given in Table A.1. Pollutant concentrations are based on Emission Limit Values (ELVs) outlined in the BAT Conclusions for Large Combustion Plants for biomass plants.

Air dispersion modelling was undertaken for the facility, which shows that, once operational, the facility will be easily compliant with the relevant air quality standards. Pollutant concentrations from the boiler stack are minimised through the provision of the following design measures, included in accordance with BAT requirements: • a SCR to reduce the nitrogen oxides; For inspection purposes only. • a bag filter for the reductionConsent of copyright of particulate/mercury; owner required for any other use. and • dry sorbent injection system to minimise SOx, HCl and HF.

A.7 Emissions to Water A.7.1 Surface Water Emissions to Sewer Surface water emissions will arise from the rain-fall run-off from roofs, roadways, hard standings and the fuel storage area within the site, which will be collected in the dedicated surface water drainage system. Surface water from the adjoining premises, to the east, will also be combined with surface water from the north-western part of the site. A.7.2 Process Effluent Emissions to Sewer Process effluent will arise from a number of sources: There will be a backwash stream from the raw water filter system, regeneration discharge streams from the boiler water treatment systems, blow down streams from the cooling tower and boiler, and waste streams from uses of service water, such as equipment wash down. The regeneration stream from the organic scavengers, which are part of the boiler water treatment system, will be treated by pH neutralisation. The effluent from the pH neutralisation system will be combined with the filter backwash stream, the

EPA Export 31-05-2018:04:29:52 Mayo Renewable IE Licence Application Attachment No. A regeneration discharge and the reverse osmosis concentrate streams from the boiler water treatment systems, the blow down streams from the cooling tower and boiler, and the waste water streams from uses of service water. The surface water will be directed through a Class 1 oil/water separator. Surface water and process effluent will be discharged to the Mayo County Council sewer, which discharges to . The treated effluent is not expected to have a significant negative effect on the sewer or Killala Bay.

A.7.3 Sanitary Effluent A packaged sewage treatment plant with a capacity for 14 population equivalent will be installed on site. Sanitary effluent will be collected from staff welfare facilities and treated on site. Sewage from the adjoining premises, to the east, will also be treated in the onsite treatment plant. The treated sanitary effluent will be discharged to the Mayo County Council sewer, which serves the site. The treated effluent is not expected to have a significant negative effect on the sewer. Irish Water, in association with Mayo County Council have recently announced a €19 million investment in the Killala, and Charlestown Sewerage Schemes, which will end the untreated discharge in Killala Bay and improve water quality in the Moy and Mullaghanoe rivers. The project, which will include the construction of a new wastewater treatment plant to serve a population equivalent (PE) of 2,300; a new pumping station; and the upgrade of the associated sewer network. When the wastewater treatment plant has been completed (due in Q1 2020), discharges from the facility will be doubly treated by this plant. A.8 Noise Emissions Baseline noise monitoring was undertaken for the facility, along with modelling of noise impacts at the nearest sensitive receptors. Cladding installed in the boiler and turbine building will abate noise emissions from For inspection internal purposes equipment. only. Consent of copyright owner required for any other use. The noise modelling assessment has shown that the facility can operate in compliance with IE Licence Limits. The facility will be designed to ensure compliance with the limits. It is not anticipated there will be any discernible noise impact at sensitive receptors associated with the Mayo Renewable facility. A.10 Baseline environment As part of the construction works for the proposed development, it can be confirmed that as part of the site demolition and site clearance works in 2015, that all waste materials (including asbestos, contaminated timber, etc.) were removed from site. There are no stockpiles on site currently that would incur environmental liabilities. A.9 Wastes All wastes arising at the Mayo Renewable Ltd facility will be removed by authorised waste collection permit holders. Wastes arising at the plant from power generation, maintenance and other typical sources will be classified in consultation with waste collectors, the European Waste Catalogue and relevant waste legislation. Hazardous waste streams will be collected, segregated and transported off-site by specialist waste management companies for appropriate treatment, recycling and/or disposal.

Mayo Renewable Power Ltd endeavours to minimise and recover wastes where possible. Where this is not feasible collection recycling or disposal of waste is undertaken using authorised waste collection permit holders and licensed waste facilities to minimise any environmental impact. A.10 Monitoring Emissions to the environment will be monitored in accordance with the requirements of the IE Licence, subject to grant and issue by the EPA. With regards emissions to sewer, a monitoring chamber will be installed upstream of the discharge point and the surface water run-off will be monitored prior to discharge to ensure compliance with the licence limits.

Three groundwater monitoring points are proposed at the facility. It is proposed that the emissions points will be monitored biannually.

A.11 Environmental Considerations The site will be operated in accordance with the an ISO 14001: 2004 accredited Environmental Management System (EMS). Mayo Renewable Ltd (MRL) will be subject to the requirements of its IE licence during operation. An Environmental Management System/Plan will be developed and will require the facility to optimise the use of energy and material resources. The primary aim of IE licensing is to prevent or reduce emissions to air, water and land, to reduce waste and to use energy efficiently. MRL will achieve these objectives by using an advanced, energy-efficient CHP method for the production of renewable energy. The following measures will be used at MRL to increase the energy efficiency: • Combustion: minimising the heat loss due to unburned gases and elements in solid wastes and residues from combustion • The highest possible pressure drop in the low pressure end of the steam turbine through the lowest possible temperature of the cooling water (fresh water cooling) • Minimising the heat loss through conduction and radiation with insulation For inspection purposes only. • Minimising the internalConsent energy of copyright consumption owner required by for taking any other appropriateuse. measures, e.g. scorification of the evaporator, greater efficiency of the feed water pump, etc.) • Preheating the boiler feed water with steam • Improved blade geometry of the turbines • Fuel drying A.12. Accidental Emissions The site will be operational 24 hours a day, 7 days a week. Personnel will be in attendance at all times to ensure an adequate response to emergency situation.
