1. Introduction

1.1 IPPC Licence Number IPPCL P0611-01

1.2 Name and Location

Electricity Supply Board West Offaly Power Shannonbridge Co Offaly.

1.3 Description of Activities

The production of energy in a combustion plant, which has a rated thermal input greater than 50 MW. West Offaly Power is one of two new peat stations and construction commenced in the Summer of 2002 with a commercial operation date (COD) of 27-1-2005. West Offaly Power station has one unit, consisting of a boiler, turbine and auxiliary plant, with an electricity generating capacity of 150MWe. The boiler operates on peat with gas oil used for start up. It is scheduled to burn approximately 1,245,000 tonnes of peat each year. Note: This report covers Environmental activities for the period of January 2010 to December 2010. The station is still operating under the construction warranty period. The contractor – Foster Wheeler and ESB concluded an agreement in December 2008 to implement in 2011 a permanent solution to the long standing corrosion problems The station will have a major outage in 2011 for 23 weeks after which the station will operate under the terms of the Corrosion Remediation Agreement and Warranty. Biomass The station conducted a number of handling trials throughout 2010 with the primary biomass, being a composition of the following biomass; sawdust ,woodchip, miscanthus and willow. In November the station completed a combustion trial on sawdust and woodchip. All details are held in the station and recorded for the purposes of Co2 verification and were done so with the conjunction of both OEE and GHG divisions of the EPA. Total Running Hrs 2010 Run Hours for 2010 was a total of 8136 hrs, which is slightly elevated in comparison to 2009 run hours as seen below in the Table. 2009 had a reduced running requirement, which was due to the flood conditions experienced in Qtr 4 which resulted in large stockpiles of peat being lost to the floods as well as railway line becoming impassable and a restriction on fuel supply occurred . The elevated run hours of 2010 could be a result of a number of factors including the cold weather conditions experienced both in early and late 2010 which resulted in reduced wind generation ensuring more thermal plant running and at higher loads due to considerable demand.

1.4 West Offaly Power Environmental Policy and Key Objectives.

West Offaly Power Generating Station is part of ESB Power Generation Business Unit. It exports approximately 137 Megawatts of electricity produced from steam generation plant burning peat and uses gas oil for start up. The station is located on the east bank of the River Shannon in an area of significant environmental importance. Environmental monitoring demonstrates that the operation of West Offaly Power does not have a significant impact on the environment.

It is the policy at West Offaly Power Generating Station to operate our facilities in a safe, efficient and environmentally responsible manner. In doing so we will:

• Define clear accountabilities and responsibilities for the management and operation of all environmental protection systems.

• Actively promote environmental awareness among all staff through communication and training programs.

• Integrate environmental concerns into all decision making and planning at the earliest stage.

• Ensure and demonstrate compliance with applicable permits, licences and relevant legal requirements, in particular Integrated Pollution Prevention and Control Licence No P0611-01.

• Ensure all significant risks are identified, evaluated and reduced to a minimum and the necessary plans and programmes are in place to minimise or eliminate potential impacts including those arising from emergency incidents.

• Put in place systems to reduce waste production and to monitor and ensure the safe disposal of all residual wastes.

• Have regard for the concerns of neighbours and other stakeholders.

• Recognise the need for special sensitivity in all operations arising from the station's location adjacent to the River Shannon, in an area of significant tourist and amenity value.

• Encourage good environmental practices from suppliers of goods and services.

• Achieve and maintain ISO 14001:2004 certification.

• Review our environmental policy and practices on an ongoing basis, to take cognisance of changes in technology and regulations.

• Minimise the consumption of energy, water and other process raw materials.

• Acknowledge the impact of peat extraction and to influence our fuel supplier towards optimum environmental management of that resource.

• Audit and review the environmental performance of the station at regular intervals and adjust our policy, procedures, objectives and practices in the light of findings and experience.

WOP will set and update appropriate targets on a regular basis in order to deliver the above objectives and ensure continuous improvement in environmental performance.

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. Those marked in green have a significant environmental role within the station. The Station Chemist is the Environmental Co-ordinator and is responsible for the co-ordination and management of all environmental activity at the station. The Environmental Co-ordinator works with the management team and environmental management group (EMG) to ensure that

• the station complies with or improves on the requirements of any environmental 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 management review, the EMS is effective, is adaptive to changing circumstances and is delivering continuous improvement.

Note: *this is water used mainly in the DeSox plant for SO2 removal and the DeSOx was not in operation in 2009 or in 2010 ** this is water used solely for make-up to the steam/water cycle Comments; It was discovered that incorrect readings of the county council water meter for the site, had resulted in the county council providing incorrect consumptions figures for the previous years. Upon discovering this issue, we engaged in a programme of water surveys and repairs over several weeks in conjunction with the water services department of the county council. We discovered three major leaks and repaired them reducing consumption figures from approx 100m3/day down to 20m3/day. We have since installed water meters on site in addition to the county council water meter, which tracks consumption and plots consumption every half hour as an aid to identify the potential for future leaks. Water consumption reduction is also one of the five main targets in 2011.

2.10 Environmental Incidents and Complaints 2.10.1 Complaints Summary

Year Date Complaint Corrective Action

2010

Jan Noise High pitched noise coming from a tail roller from a fuel belt in the screening room in the BNM site section during cold weather. Several maintenance programs were engaged to reduce the noise- however the noise remained intermittent. A specialist noise monitoring survey was conducted in this area- it was determined the problem was known as “Squeal Noise”. It occurs when there are relatively large bearings used under a radial load. Squeal noise is most likely to occur in winter with cold weather conditions. Since the complaint the station has ensured that the door to the screening room remains closed throughout the day and night. No complaints have occurred since this measure was taken.

3.3 E-PRTR 2010

ESB West Offaly Power expected to carry out a study on heavy metals in air emissions in 2009 to coincide with similar work in other ESB power plant, however this has been postponed in other plants to 2010

3.3.1 Methodology for determination of mass emissions

The methodology for the determination of mass emissions for inclusion in the PER is as follows. The flue gas volume generated is not measured directly in the station CEMS equipment. It is, however, possible to calculate flue gas volumes under standard conditions (as is required to express measured emission concentrations) to a high degree of accuracy based on knowledge of fuel composition, calorific value and activity. NOx

The NOx has an ELV of 200 mg/Nm3. It is proposed that the NOx emitted be calculated on the basis of the

fuel quantity consumed, its consequent flue gas volume (under standard conditions) and the average NOx concentration measured over the reporting period SO2 Similarly, the SO2 is limited to an ELV of 200 mg/Nm

3 and is measured by an extractive system in the CEMS

system. It is proposed that the SO2 emitted be calculated on the basis of the fuel quantity consumed, its consequent flue gas volume (under standard conditions) and the average SO2 concentration measured over the reporting period. Particulate The dust has an ELV of 30 mg/Nm

3 and is measured by the CEMS. It is proposed that the dust emitted be

calculated on the basis of the fuel quantity consumed, its consequent flue gas volume (under standard conditions) and the average dust concentration measured over the reporting period. CO2

The calculation of CO2 emissions is as agreed for verification of compliance with the Emissions Trading Directive: CO2 emitted = Fuel consumed (in tonnes) x Fuel Carbon (C content as %/100) x Conversion Factor (3.667) x Oxidation Factor (as measured) In WOP the fuel is subject to a complex sampling regime to define its characteristics. 36 Primary samples are taken each day. These are combined and reduced to a daily sample that is analysed for moisture content. A week’s set of daily samples is used to generate a period sample and that is used to calculate C and H2 compositions. Analysis of C content and Carbon in Ash is done by an independent laboratory to EN ISO 17025. Fuel consumption is measured by independently calibrated belt-weighers. A calibrated weighbridge is used to measure deliveries of peat by road. The oxidation factor is calculated from the product of ash quantity and fraction of carbon-in-ash. Exclusion of other Substances. Please see 2008 AER for explanation on the exclusion of, Heavy Metals, Ammonia, Hydrazine and Ortho-phosphate .:

IPPCL P0611-01 states the following under condition 5: Emission to Air. 5.7 The licensee shall report the total annual emissions of SO2, NOx, and dust (as total suspended particulates) annually as part of the AER. When continuous monitoring is used, the licensee shall separately calculate for each substance the mass emitted each day, on the basis of volumetric flow rates of waste gases. The basis of the calculation of the pollutants in the Table is that the ultimate analysis data for the fuel was used to calculate dry flue gas volumes generated under standard conditions of 6% O2 dry and hence multiplied out to estimate this for the annual tonnage (including the contribution of gas oil to the total flue gas volume). The concentrations recorded on a 24 hour average by the CEMS was then used to determine the amount emitted annually NCVs of fuels used in 2010

4 Licence Specific Reports

4.1 Noise Monitoring Reports

See Appendix 4.2 Underground Tanks and Pipelines CCTV inspection surveys were conducted in 2008. Copies of the survey are held within the station for viewing at any time by the Agency. The next survey is due in 2011.

4.3 Report on List 1 and List 11 Substance Reduction

(i) List I and List II Substance Reductions

Hydrazine, Trisodium Phosphate and Sodium Hypochlorite were originally considered during the application of this licence, following an internal review it was deemed that other treatment technologies could be used in their place therefore none of these items are currently used in the station for operation. 4.4 Energy Efficiency Audit Report Summary General The generating plant at West Offaly Power (WOP) station consists of one circulating fluidised bed boiler (CFB) and a Fuji steam turbine with a capacity of 150Megawatts. . West Offaly Power is one of the most modern and efficient generating stations of its kind in the world with a conversion efficiency of the order of 37%. The CFB is the most up to date technology available. It operates almost exclusively on peat with gas oil used only in start-up. All possible operations are computerised and automated. Sophisticated monitoring systems provide immediate warning of any deviation from normal standards. The following are the configuration and operating particulars to year end 2010. The overall efficiency for 2010 was 36%.

Design Parameters The plant is required to meet design operating conditions and efficiency and this determined by an ‘Acceptance Test’ prior to takeover of the plant by ESB. The ‘Acceptance Test’ was successfully carried out in Nov-Dec 2004 and the plant was accepted by ESB on commercial operation date (COD) of the 28-1-‘05. All operating parameters of the plant are recorded on a computer system called the DCS. All operating parameters are analysed by a computer system known as the Operating Information System (OIS). These monitoring systems provide immediate warning of any deviation from normal standards. Plant Corrosion The contractor Foster Wheeler and ESB reached agreement in December 2008 on the implementation of corrective measures to eliminate the corrosion problems that have limited the output from the plant since commissioning in Jan 2005. Program planning has commenced by both parties and the corrective action will be implemented in the Summer of 2011 from 31

th of March till the 16

th of September.

Review of Efficiency Monitoring Practice in the Station Unit efficiency is reported by Operations staff to the Production Manager who reviews the information on an ongoing basis. Appropriate remedial action, where necessary, is decided upon and progressed through the maintenance/operations work planning system, known as ‘Maximo’. The Production Manager in turn reports efficiency performance to the Station Manager on a regular basis, but daily information is also provided. Future Plans Environmental During design all environmental considerations were taken into account and during construction all necessary equipment was installed. Periodically minor improvements have been instituted and this will continue to be the case with station staff continually assessing procedures/plant for improvement. Each year a list of environmental objectives are drawn up for continual environmental improvement and these are monitored by station management for implementation A number of Environmental & Sustainability projects are planned for 2011, these are incorporated into the stations Targets &Objectives for 2011 or the stations environmental management programme. Three environmental projects from 2010 have been pushed out to early 2011.Therefore a total of 8 targets and Objectives are ongoing for 2011. 4.5 Review of Environmental Liabilities Insurance Cover / Environmental Risk Assessment Report
