Introduction 1.1 IPPC Licence Number P Name and Location Electricity Supply Board Poolbeg Generating Station Pigeon House Road Dublin Description of Activities The production of energy in combustion plant, rated thermal input of which is greater than 50 MW. Poolbeg Generating Station currently has a total electricity generating capacity of 470MWe from a combined cycle gas turbine (CCGT) generating unit. The CCGT plant is made up of two gas turbines of 155 MWe each and a steam turbine of 170 MWe. The station is fired on natural gas from the national gas network and gas oil is stored as a secondary fuel which is normally only used for testing purposes and in times of grid system emergency. On 31 st March 2010, 510 MW of Thermal Generating Units ceased to operate. The CCGT will continue to operate into the future on the Poolbeg site. Note during 2011 the two Gas Turbine and Steam Turbines underwent major overhauls and were offload during the following periods; Gas Turbine 14 8 th April 2 nd June Gas Turbine th July 23 rd September Steam Turbine 8 th April 6 th June 1.4 Environmental Policy See page 5. 3

4 1.5 Environmental Management Structure and Responsibility Environmental Management is fully integrated into all aspects of management on site. The management structure is shown in figure 1.1. The Station Chemist is currently the Environmental Co-ordinator and is responsible for the co-ordination of all environmental activity at the station. The Environmental Co-ordinator works with the management team and environmental management group to ensure that The station prioritises full compliance with the provisions specified under its IPPC licence, other licences, planning permission and environmental legislation. The Station s EMS is operated and maintained to the required standard. By way of audit and review cycle, the EMS is effective, is adaptive to changing circumstances and is delivering continuous improvement. The station has been ISO accredited since April 1999 and received it original Integrated Pollution Control Licence in April 2002, a revised Integrated Pollution Prevention and Control licence was issued in December

5 POOLBEG STATION ENVIRONMENTAL POLICY STATEMENT Poolbeg Generating Station is situated in the heart of Dublin Bay, we are very aware of the areas of environmental importance in the locality. Poolbeg is bounded on the north by the River Liffey and to the east and south by Dublin Bay. South Dublin Bay is designated as a Natural Heritage Area, Special Area of Conservation and a Special Protection Area for Birds. In the vicinity is also the Bull Island Nature Reserve, Tolka Estuary Mudflats and Irishtown Nature Park. We are also aware of our presence in the local community. Poolbeg station has a total electricity generating capacity of 470MWe from a combined cycle gas turbine (CCGT) generating unit. The 510 MW Thermal power station ceased operation on 31 st March We at Poolbeg commit ourselves to meeting customer demand for electricity in a safe, efficient, sustainable and environmentally responsible manner, while recognising the technical and financial constraints within which we must operate. Environmental risks are minimised by the use of appropriate technologies and working procedures. We strive for continual improvement in our environmental performance and prevention of pollution through the operation of the station s environmental management system and adherence to our Integrated Pollution Prevention and Control Licence No. P By maintaining both ISO and OHSAS accreditation, we will continue to operate and improve on our Environmental and Safety Performance. We carry out our activities in conformance with the policy principles outlined below: Responsibilities and Accountabilities Regard the achievement of the station s annual environmental targets and objectives as a line management responsibility requiring personal involvement and commitment from all management and staff. Ensure that appropriate resources are allocated to environmental matters. Compliance Issues Ensure compliance with the terms and conditions of our IPPCL, Greenhouse Gas Permit and all other relevant legal requirements and conformance with all relevant in-house standards and procedures relating to environmental protection with proper monitoring and control systems in place. Use of Natural Resources Use environmental resources, including air, land and water in a responsible manner and make every effort to conserve finite natural resources by efficient use and careful planning. Energy Conservation Maintain the ongoing assessment of the efficiency with which energy is generated and used within the station with a view to optimisation. Waste Materials Reduce waste generation as far as possible and ensure supervision of the disposal of waste, to minimise its impact on the environment. Evaluate opportunities to recycle waste materials and implement these where practicable. Environmental Awareness Actively promote environmental awareness among staff through communication and training programmes and take into account the impacts on and concerns of the local community. Suppliers of Goods and on Site Services Ensure that appropriate suppliers of goods and on site services assess the environmental impacts in their dealings with Poolbeg. We will also encourage responsible environmental management and insist that they conform to all relevant legislation. For suppliers of on site services we will advise them of our site specific environmental policy and relevant environmental documentation. Auditing and Reporting Conduct regular internal and external audits to assess the level of performance and compliance with the environmental requirements of the company and regulatory bodies. Report, as appropriate, to staff, regulatory bodies and other interested parties. Review Carry out regular reviews of environmental policies and practices and keep abreast of any changing legislation or technology.

SW1 Condenser Cooling Water SW2 Water treatment neutralisation tank Units 1, 2 and 3 SW3 Water treatment neutralisation tank CCGT SW4 Boiler blowdown (Unit 1) SW5 Boiler blowdown (Unit 2) SW6 Boiler blowdown (Unit 3) SW7 Boiler blowdown (CCGT B14) SW8 Boiler blowdown (CCGT B15) SW10 Screen Wash Water SW11 Screen Wash Water Following the closure of Poolbeg Thermal Station on 31 st March 2010 there will be no further discharges from the following emission points SW2, SW4, SW5, SW6 and SW10 and hence monitoring has been ceased at these emission points. Monitoring of the remaining operational emission points SW1, SW3, SW7, SW8 and SW11 is carried out in accordance with Schedule 2(iii) of Poolbegs IPPC license Emission Point Reference Number SW1 - Condenser Cooling Water Temperature Table 2.1 SW1 Monthly average temperature differentials. Month Emission Limit Value Station Average T o C C January 5.6 February 6.8 March 6.8 April May 7.4 ( Until 8 th April only) CW not in service June 5.0 July 4.9 August 3.5 September 3.9 October 5.0 November 4.8 December 5.0 Note: The steam turbine and cooling water (CW) system was not in-service from 8 th April - 6 th June. 7

8 Compliance with Emission Limit Values There was 15 hourly averages greater than 10 o C but less than 11.5 o C this equates to 99.77% of hourly operating values being less than 10 0 C. There was one ELV exceedence for a period of twenty minutes, see Table 2.30 for summary of reportable incidents. Flow The maximum volume to be emitted in any one day of 2,520,000m 3 and maximum rate per hour of 105,000m 3 was not exceeded in this reporting period. The capacity of the CCGT pumps in Poolbeg is such that the maximum flow required to support full station output is 43,200 m3/hour and it is therefore not foreseen that the licence volume would be exceeded under any circumstances. From the individual unit operating records, the volume of cooling water emitted for the reporting period is calculated at 212,766,696 m 3 vs. a licensed volume emission of 919,800,000 m 3. Chlorine The emission limit value of 0.1mg/l has not been exceeded in this reporting period.

57 Comments on Ground Water Results from 2011 Results have been screened against the Groundwater Regulation Threshold Values (2010) and EPA Interim Guideline Values (IGVs) for groundwater. Results from the two sampling rounds indicate that: February 2011 Similar to previous rounds the concentrations of TPH, BTEX and MTBE were not detected above the method detection limit (MDL); PAH concentrations have increased in MW2. Concentrations of Benzo(a)pyrene, Total 4 PAHs and Total 17 PAHs exceeded the IGVs; PAH concentrations have decreased in MW4. However, concentrations of Benzo(a)pyrene, exceeded IGVs. Total coliform concentrations exceeded the IGVs in samples collected from BH1, MW2, MW3, and MW4, the impact is considered to be minor. (Refer also to report submitted 25/01/2011) July 2011 Similar to previous rounds the concentrations of TPH, BTEX and MTBE were not detected above the method detection limit (MDL); PAH concentrations were relatively low in all four samples collected with reported concentrations below MDL or appropriate IGV. This is broadly consistent with previous monitoring rounds; Benzo(a)pyrene concentrations have decreased in MW4 and MW2 since February 2011 when they exceeded the IGV. Total coliform numbers exceeded the IGV in samples collected from BH1, MW02, MW03, and MW04 with a slight increase in numbers of coliforms noted since February However, overall, the impact is considered to be minor.
