Boliden Tara Mines Limited Annual Environmental Report 2009 _______________________________________________________________________________________________________
NON-TECHNICAL SUMMARY INTRODUCTION Boliden Tara Mines Limited, the largest operating zinc and lead mine in Europe, is located at Knockumber, 2 km west of Navan in County Meath. Originally sited in a rural area, expansion of Navan has resulted in the development of residential areas nearer to the mine although much of its surroundings remain flat agricultural land drained by prolific fishing rivers. The River Blackwater, which flows into the River Boyne, passes over the orebody and forms a surface intersection feature between what is now referred to as the „Main orebody‟ and the „Nevinstown orebody‟. Production mining and processing has been in operation since 1977. Tara currently produces between 2.6 and 2.7 million tonnes of ore per annum, resulting in 400,000 tonnes of zinc and lead concentrate. Approximately 50% of the residual material is mixed with cement and returned to the mine as backfill to stabilise the worked out areas while the other 50% is pumped into the tailings storage facility (TSF) located 3km north of the mine site at Randalstown. The TSF, enclosing a footprint area of approximately 170 hectares, serves as containment for tailings to settle and consolidate, as well as a treatment storage area for the water which is circulated back to the processing plant at Knockumber prior to discharge under license to the River Boyne.
Randalstown Tailings Storage Facility
Environmental Management has always been at the core of operations at Tara since the development of the mine commenced in 1973. Today Company activities are carried out in compliance with our IPPC licence. All activities and emissions are controlled, operated and maintained as set out in conditions of this licence. Tara‟s environmental management system is accredited to the internationally recognised ISO 14001 Environmental Standard awarded by the National Standards Authority of Ireland in November 2007.

Mining and Processing The Tara orebody is mined by underground cut and fill excavation methods. The ore is removed in alternative vertical slices, leaving pillars of rock to provide stability. The mined out areas are then backfilled with tailings sand, cement and/or development waste. When the backfill has consolidated and of sufficient strength to provide stability, the pillars are removed. Development blasting occurs at the end of the day and night shift while production blasting occurs at the end of day shift. The mined ore is removed to the primary jaw crushing stations, either by loader, truck or conveyor, before being hoisted to surface. The hoisted ore then passes by conveyor system to a coarse ore storage building on surface and conveyed to an autogenous grinding circuit. Having passed through this circuit the ground material is mixed with water to produce a finely ground ore slurry. It is then pumped to the flotation stage of the process where combinations of chemical agents are used to selectively remove both zinc and lead minerals. These minerals, called concentrates, have a high water content, are passed through a thickner and then pumped to dewatering pressure filters. The final products zinc and lead concentrate is then taken by rail to Dublin Port from where it is shipped to smelters in Europe.

Boliden Tara Mines Limited Annual Environmental Report 2009 _______________________________________________________________________________________________________
New AG Mill In October 2009 a new Autogenous Grinding (AG) mill was installed to replace the old crushing and grinding circuit in the processing plant. Autogenous grinding is a process that uses larger lumps of ore to grind smaller pieces of ore (the ore being used to grind itself). Since processing operations began at Tara in 1977 ore comminution (size reduction) has been achieved using crushers and steel grinding mills. The AG milling circuit has replaced these conventional crushing and grinding systems, and delivers a similar product size distribution to flotation. The old system was a combination of wet and dry processes with dust generated at the dry crushing process which had to be ventilated. Dust was extracted and passed through a wet scrubber before being emitted to the atmosphere through the ventilation stack IPPCL Ref. A2-2. The new AG circuit is a completely wet enclosed system thereby eliminating any source of dust. The ventilation system is no longer necessary thereby resulting in the elimination / decommissioning of atmospheric emission point A2-2. With the new AG mill in place, the three main noise sources from the old grinding system have been decommissioned. This has a positive impact at the nearest residence reducing noise emission levels by more than 1dB.
Old crushing and grinding system
New autogenous grinding mill
Waste Management A new, dedicated waste segregation compound (concrete based) has been constructed for non hazardous waste including scrap steel, wood waste, rubber and general waste. Non-hazardous waste streams from surface and underground are now transferred to this new waste transfer compound. This waste compound replaces the need to transfer / store waste in an unbunded area. The waste compound is manned during operating hours and is under constant CCTV surveillance. New waste management procedures for all hazardous and non-hazardous waste have been updated to take cognisance of this development. Extension to Randalstown Tailings Storage Facility (TSF) Stage 5 In September 2009 Tara submitted a Planning Application and associated EIS to Meath County Council (MCC) for a 4 metre vertical extension (with a 5.6 million m3

storage capacity) to the existing Tailings Storage Facility (TSF), for the purpose of extending the life of the mine. The development, to be called the Stage 5 development, will be constructed on the footprint of the existing tailings storage facility, which occupies an area of 170 hectares.
Electro Fishing An Electro fishing survey was completed along the River Boyne during September 2009 (see Section 3.4 of AER). As a requirement under our licence this fish population survey and analysis of heavy metals in fish tissues samples collected is carried out every 5 years. The survey is carried out both upstream and downstream of discharge point (SW 1) along the River Boyne. Closure Plans A review of the Closure, Restoration and Aftercare Management Plan (CRAMP) for Boliden Tara Mines Limited was completed in March 2009 and submitted to the EPA, MCC and Department of Marine and Natural Resources. The closure plans for both the Knockumber minesite and the Randalatown TSF fulfil the requirements of IPPCL Conditions 13.3 and 14.2.
MONITORING Groundwater Monitoring Groundwater monitoring is carried out in accordance with Schedule 5(i) of Tara‟s IPPCL. A summary of monitoring data is presented in Section 2.12 of this AER (values are based on average concentrations). The existing groundwater monitoring network in the vicinity of the Randalstown TSF involves monthly sampling at 25 locations from overburden (OB) and bedrock (BR) boreholes and biannual sampling water from 11 domestic wells. The original groundwater monitoring network has evolved and expanded over the years as development has taken place (the TSF has been built and operated in five stages during the period 1974 to 2006). All water quality data is reviewed in line with relevant water quality standards. The EPA Interim Guideline Values (IGV) for Ireland are used as a guide for comparison with measured concentrations in groundwater, in addition to Irish drinking water standards. Sulphate is used as the indicator parameter for monitoring potential contamination of groundwater in the vicinity of the TMF. Sulphate concentrations in boreholes in the immediate vicinity of the TSF exceed Irish drinking water standards of 250mg/l and IGV of 200mg/l. However, these elevated levels are contained to a 50m distance from the interceptor channel which is a designed catchment boundary drain around the TSF. The 2009 sulphate concentrations in all boreholes at more than 50m from the TSF met water quality standards. Elevated concentrations of parameters (manganese, potassium, ammonia) a consequence of natural geochemical influences or non-point source contamination (as may arise from agricultural practice) show no discernible pattern across the area, Environmental Department Non-technical summary
iv
Boliden Tara Mines Limited Annual Environmental Report 2009 _______________________________________________________________________________________________________
occurring both upstream and downstream of the TSF. The spatial distribution of these elevated concentrations mean that the TSF is unlikely to be the source. Minor exceedance of IGV standards of chloride, nitrite, calcium and copper was demonstrated on some occasions. All other parameters tested in the boreholes met the relevant water quality standards. Of the 11 domestic well monitored, only 3 are in use and none for domestic purposes. Concentrations of manganese, potassium and ammonia above drinking water standards are consistent with the trend they are naturally occurring in groundwater in the area and their spatial distribution means the source unlikely to be the TSF. There are very minor exceedances of IGV standards in chloride and copper. No other parameters in the domestic wells tested exhibited elevated concentrations. Surface water Monitoring Surface water monitoring is carried out in accordance with Schedule 4(i) of Tara‟s IPPCL. A summary of monitoring data is presented in Section 2.11 of this AER (values are based on average concentrations). River and stream samples are taken monthly from 13 locations on the River Boyne, River Blackwater and Yellow River and on the Simonstown and Duog Streams, representing locations upstream and downstream of the TSF, the minesite and the discharge point to the River Boyne. Values indicate no discernable disparity between upstream and downstream samples. For the most part all parameters analysed in surface waters conform to the standards required for both salmonid waters (EC Freshwater Fish Directive (78/656/EEC)) and drinking water. Elevated levels of suspended solids and other elements (iron, manganese and aluminium) were detected in November are likely to be associated with heavy rainfall and flooding during that period. Ambient Air Monitoring Continuous ambient air monitoring is carried out at 6 sampling locations around the minesite and TSF in accordance with IPPCL Schedule 1(v). A summary of monitoring data is presented in Sections 2.9 of this AER. This high volume particulate sampling is performed in accordance with the requirements of Air Quality Standards Regulations SI 244 of 1987 and with the requirements of the Directive (99/30/EC). Dust deposition monitoring is carried out at 12 sampling locations around the minesite and TSF. A summary of monitoring data is presented in Section 2.10 of this AER. Samples are collected on a monthly basis and analysed in accordance with IPPCL Schedule 1(v). Monitoring is performed using Bergerhoff gauges specified in the German Engineering Institute VDI 2119 entitled “Measurement of Dustfall Using the Bergerhoff Instrument (Standard Method)” in accordance with TA Luft Standard. There was no exceedence of emission limit value in 2009. Noise and Vibration Monitoring Continuous vibration monitoring is being carried out at a minimum of 6 locations around the minesite and SWEX area, the number depending on requests from residents. A summary of monitoring data is presented in Section 2.13 of this AER. Environmental Department Non-technical summary

SECTION 1.1.2
Pollution Emission Register (PER) (Condition No. 2.4)
Prior to 2007 a Pollution Emission Register (PER) Proposal and PER Report was prepared annually by Tara in accordance with IPPC Licence Condition 2.4 and submitted as part of the AER in accordance to the EPER (European Pollution Emissions Register) reporting mechanism. Regulation (EC) No 166/2006 concerning the establishment of a European Pollutant Release and Transfer Register (PRTR) was adopted in 2006. This Regulation, which aims to enhance the availability of information to the general public on the sources and amounts of emissions to air, water and land from European industry is the successor to the EPER reporting mechanism. Now all emissions and waste transfer records are reported via the EPA’s AER / PRTR Emissions Data Reporting Workbook. To prepare for the implementation of this Regulation Tara:
Carried out a review of the PRTR list (91 specified pollutants) and identified those which were / present on the site. Quantified all deliberate, accidental, routine and non-routine releases to air, water and land. Quantified all transfers of hazardous or non-hazardous wastes. Reviewed methods of measurement for air and water pollutants used at Tara.
SECTION 1.1.3
Documentation (Condition 2.5)
Tara’s EMS is made up of a series of components; documentation describes the system and how its components work together. All documents relating to the EMS are ‘controlled’ and maintained within a dedicated electronic Document Management System named Centuri. The system conforms to the strict requirements of the ISO 14001 standard.
SECTION 1.1.4
Corrective Action (Condition 2.6)
The Environmental Department has ‘Corrective Action Procedures’ in place, should an environmental incident occur. These procedures outline the course of action to be taken and the notification procedure to be followed. Responsibility for initiating investigation and corrective action lies with the relevant Department Supervisor. The Environmental Department ensures that correct procedures are followed. Procedures for dealing with environmental incidents are outlined in the Emergency Response Procedures (ERP) which addresses potential emergency situations / events that may arise onsite based on documented experience at Tara and anecdotal information from other, comparable, mining operations. This ERP was designed to prepare for, mitigate, respond to and recover from an emergency. Periodic tests are carried out to ensure effectiveness of procedures in the ERP. Notification procedures are in accordance with IPPC License Condition 4 and the Agency is notified as soon as practicable after an occurrence. A summary report of incidents reported to the Agency and other authorities throughout the year is submitted annually as part of the AER.

An ongoing programme of Environmental Awareness and Training is carried out for all company employees and contractors. Training needs are identified on an ongoing basis and actions taken to ensure the provision of appropriate training. Monthly EHS crew meetings provide the forum to raise environmental awareness for employees and has been extended to all regular contractors during 2009. All visiting contractors working on behalf of the Company and all visitors receive induction training, including environmental awareness information, upon arrival on site. The Environmental Department supports and advises all departments within the company on all relevant aspects of our IPPC Licence and environmental aspects of the Company's activities, products and services that could be affected by their work.
SECTION 1.1.6
Responsibilities (Condition 2.8)
The successful implementation of an EMS calls for a commitment from all persons working for the Company or on its behalf. As part of this commitment, top management has designated specific personnel with defined responsibility and authority for implementing the EMS. Resources include human resources and specialized skills, organizational infrastructure, technology and financial resources. All employees should clearly understand their environmental roles and responsibilities, as well as understand the importance of the environmental targets and objectives and the affect their actions may have upon them. Ultimate implementation of the Company Environmental Policy and operation of the EMS lies with the Managing Director. The role of day to day running of the Environmental Department and the implementation of the EMS is delegated to the Environmental Superintendent. It is the responsibility of the Environmental Superintendent to ensure that the EMS is established, implemented and maintained and regularly reported to top management on the performance of the EMS, including recommendations for improvement.
SECTION 1.1.7
Communications (Condition 2.9)
The company operates an ‘open door’ policy with respect to environmental practice, monitoring and control. All environmental data, including submissions to the EPA in compliance with IPPC Licence conditions, are available for inspection at the Company’s Environmental Department offices strategically located, for accessibility, along the N3, Kells Road. Environmental personnel are available for consultation during normal working hours without the need for security clearance and every effort is made to cooperate with members of the public. An Environmental Community Relations Policy is in place and reviewed annually. There is a procedure in place for dealing with both the internal and external communication of environmental matters. All communication records are controlled in the Document Management System.

NON-COMPLIANCE / INCIDENT SUMMARY REPORT January - December 2009
Date
Non-Compliance / Incident
Corrective Action
EPA Audit 12/07/09
Waste Storage Was oil was stored in a non-bunded area on a gravelled area (non-compliance with Condition 9.6.1 and 9.6.3)
The two mobile bunds observed have been relocated to the nearby waste oil handling facility. This area is covered and has a concrete base. This measure should eliminate the potential for spillage onto unprotected ground.
EPA Audit 12/07/09
Spill Control No spill control kit was accessible at the waste oil separator compound (noncompliance with Condition 9.6.7). A spill of oil on permeable gravel outside the bund area was noted (non-compliance with Condition 9.5.1)
The area around the waste oil handling area has been cleaned up and a spill kit has been put in place in the waste oil compound. Workers operating in this area have been trained regarding proper waste handling procedures. Adequate supplies of containment booms and oil absorbent materials are kept as stock items.
Bund Integrity Testing The Sulphuric Acid Bund was repaired during 2007 and subject to bund integrity test on 31/10/2007. This test report was found to be deficient (non-compliance with Condition 9.6.1)
Remedial work will be carried out on the sulphuric acid bund and should be complete at the end of the 3Q 2010. Following completion an integrity test will be carried out to satisfy the requirements of the Agency. The small stainless steel containment tank located in a new concrete bund structure (adjacent to the main bund) has not been tested. However, this is designed only to capture any spills and washings that may arise from acid delivery. The level of captured acid is monitored online by the mill central control room operator and emptied automatically, being recycled to the mill. Very small amounts of acid spills are in this tank at any instance in time. Because of buoyancy issues regarding the small lightweight stainless tank it is considered inappropriate to fill this secondary bund with water. All relevant bunds on site have been labeled appropriately and locations indicated on a site plan. A register of these bunds has been compiled and will be forwarded with this AER.

December 2009
Elevated Antimony in Effluent Discharge Analysis of effluent discharge samples reported on 29/12/2009 has shown elevated Antimony levels. The reported data covers the period from 11/12/09 to 28/12/09 and Antimony levels ranged from 1.04mg/l to a maximum level of 1.29mg/l (marginally above the Emission Limit Value of 1.0mg/l).
Environmental Department
Corrective Action
Following reporting of the results, discharge to the River Boyne was immediately shut down on 29/12/2009 at 16.30hrs. A control system is now in place where water from the mine with low levels of Antimony is blended with process water. Investigation into the source of Antimony in the process water and the long term control measures is continuing and when completed a summary of the findings will be forwarded to the Agency. This was reported to the EPA, Meath County Council and Eastern Regional Fisheries Board.

Energy Performance Indicators: Electricity consumption per ton was above target for 2009. Mine power consumption correlates poorly with tonnage and base load has increased possibly due to increased ventilation and water pumping. Mill power consumption was consistently below budget and below 2008 levels until commissioning of the AG mill when low throughput rates had a severe adverse effect. Liters diesel per ton hoisted also ran above target since the middle of the year – this is due to increased underground development activity. The higher unit rate targets set for 2010 reflect planned increases in ventilation and water pumping in the mine and an increase due to the Autogenous Mill.

Boliden Tara Mines Limited Annual Environmental Report 2009 _______________________________________________________________________________________________________
NON-TECHNICAL SUMMARY INTRODUCTION Boliden Tara Mines Limited, the largest operating zinc and lead mine in Europe, is located at Knockumber, 2 km west of Navan in County Meath. Originally sited in a rural area, expansion of Navan has resulted in the development of residential areas nearer to the mine although much of its surroundings remain flat agricultural land drained by prolific fishing rivers. The River Blackwater, which flows into the River Boyne, passes over the orebody and forms a surface intersection feature between what is now referred to as the „Main orebody‟ and the „Nevinstown orebody‟. Production mining and processing has been in operation since 1977. Tara currently produces between 2.6 and 2.7 million tonnes of ore per annum, resulting in 400,000 tonnes of zinc and lead concentrate. Approximately 50% of the residual material is mixed with cement and returned to the mine as backfill to stabilise the worked out areas while the other 50% is pumped into the tailings storage facility (TSF) located 3km north of the mine site at Randalstown. The TSF, enclosing a footprint area of approximately 170 hectares, serves as containment for tailings to settle and consolidate, as well as a treatment storage area for the water which is circulated back to the processing plant at Knockumber prior to discharge under license to the River Boyne.
Randalstown Tailings Storage Facility
Environmental Management has always been at the core of operations at Tara since the development of the mine commenced in 1973. Today Company activities are carried out in compliance with our IPPC licence. All activities and emissions are controlled, operated and maintained as set out in conditions of this licence. Tara‟s environmental management system is accredited to the internationally recognised ISO 14001 Environmental Standard awarded by the National Standards Authority of Ireland in November 2007.

Boliden Tara Mines Limited Annual Environmental Report 2009 _______________________________________________________________________________________________________
Mining and Processing The Tara orebody is mined by underground cut and fill excavation methods. The ore is removed in alternative vertical slices, leaving pillars of rock to provide stability. The mined out areas are then backfilled with tailings sand, cement and/or development waste. When the backfill has consolidated and of sufficient strength to provide stability, the pillars are removed. Development blasting occurs at the end of the day and night shift while production blasting occurs at the end of day shift. The mined ore is removed to the primary jaw crushing stations, either by loader, truck or conveyor, before being hoisted to surface. The hoisted ore then passes by conveyor system to a coarse ore storage building on surface and conveyed to an autogenous grinding circuit. Having passed through this circuit the ground material is mixed with water to produce a finely ground ore slurry. It is then pumped to the flotation stage of the process where combinations of chemical agents are used to selectively remove both zinc and lead minerals. These minerals, called concentrates, have a high water content, are passed through a thickner and then pumped to dewatering pressure filters. The final products zinc and lead concentrate is then taken by rail to Dublin Port from where it is shipped to smelters in Europe.

Boliden Tara Mines Limited Annual Environmental Report 2009 _______________________________________________________________________________________________________
New AG Mill In October 2009 a new Autogenous Grinding (AG) mill was installed to replace the old crushing and grinding circuit in the processing plant. Autogenous grinding is a process that uses larger lumps of ore to grind smaller pieces of ore (the ore being used to grind itself). Since processing operations began at Tara in 1977 ore comminution (size reduction) has been achieved using crushers and steel grinding mills. The AG milling circuit has replaced these conventional crushing and grinding systems, and delivers a similar product size distribution to flotation. The old system was a combination of wet and dry processes with dust generated at the dry crushing process which had to be ventilated. Dust was extracted and passed through a wet scrubber before being emitted to the atmosphere through the ventilation stack IPPCL Ref. A2-2. The new AG circuit is a completely wet enclosed system thereby eliminating any source of dust. The ventilation system is no longer necessary thereby resulting in the elimination / decommissioning of atmospheric emission point A2-2. With the new AG mill in place, the three main noise sources from the old grinding system have been decommissioned. This has a positive impact at the nearest residence reducing noise emission levels by more than 1dB.
Old crushing and grinding system
New autogenous grinding mill
Waste Management A new, dedicated waste segregation compound (concrete based) has been constructed for non hazardous waste including scrap steel, wood waste, rubber and general waste. Non-hazardous waste streams from surface and underground are now transferred to this new waste transfer compound. This waste compound replaces the need to transfer / store waste in an unbunded area. The waste compound is manned during operating hours and is under constant CCTV surveillance. New waste management procedures for all hazardous and non-hazardous waste have been updated to take cognisance of this development. Extension to Randalstown Tailings Storage Facility (TSF) Stage 5 In September 2009 Tara submitted a Planning Application and associated EIS to Meath County Council (MCC) for a 4 metre vertical extension (with a 5.6 million m3

storage capacity) to the existing Tailings Storage Facility (TSF), for the purpose of extending the life of the mine. The development, to be called the Stage 5 development, will be constructed on the footprint of the existing tailings storage facility, which occupies an area of 170 hectares.
Electro Fishing An Electro fishing survey was completed along the River Boyne during September 2009 (see Section 3.4 of AER). As a requirement under our licence this fish population survey and analysis of heavy metals in fish tissues samples collected is carried out every 5 years. The survey is carried out both upstream and downstream of discharge point (SW 1) along the River Boyne. Closure Plans A review of the Closure, Restoration and Aftercare Management Plan (CRAMP) for Boliden Tara Mines Limited was completed in March 2009 and submitted to the EPA, MCC and Department of Marine and Natural Resources. The closure plans for both the Knockumber minesite and the Randalatown TSF fulfil the requirements of IPPCL Conditions 13.3 and 14.2.
MONITORING Groundwater Monitoring Groundwater monitoring is carried out in accordance with Schedule 5(i) of Tara‟s IPPCL. A summary of monitoring data is presented in Section 2.12 of this AER (values are based on average concentrations). The existing groundwater monitoring network in the vicinity of the Randalstown TSF involves monthly sampling at 25 locations from overburden (OB) and bedrock (BR) boreholes and biannual sampling water from 11 domestic wells. The original groundwater monitoring network has evolved and expanded over the years as development has taken place (the TSF has been built and operated in five stages during the period 1974 to 2006). All water quality data is reviewed in line with relevant water quality standards. The EPA Interim Guideline Values (IGV) for Ireland are used as a guide for comparison with measured concentrations in groundwater, in addition to Irish drinking water standards. Sulphate is used as the indicator parameter for monitoring potential contamination of groundwater in the vicinity of the TMF. Sulphate concentrations in boreholes in the immediate vicinity of the TSF exceed Irish drinking water standards of 250mg/l and IGV of 200mg/l. However, these elevated levels are contained to a 50m distance from the interceptor channel which is a designed catchment boundary drain around the TSF. The 2009 sulphate concentrations in all boreholes at more than 50m from the TSF met water quality standards. Elevated concentrations of parameters (manganese, potassium, ammonia) a consequence of natural geochemical influences or non-point source contamination (as may arise from agricultural practice) show no discernible pattern across the area, Environmental Department Non-technical summary
iv

occurring both upstream and downstream of the TSF. The spatial distribution of these elevated concentrations mean that the TSF is unlikely to be the source. Minor exceedance of IGV standards of chloride, nitrite, calcium and copper was demonstrated on some occasions. All other parameters tested in the boreholes met the relevant water quality standards. Of the 11 domestic well monitored, only 3 are in use and none for domestic purposes. Concentrations of manganese, potassium and ammonia above drinking water standards are consistent with the trend they are naturally occurring in groundwater in the area and their spatial distribution means the source unlikely to be the TSF. There are very minor exceedances of IGV standards in chloride and copper. No other parameters in the domestic wells tested exhibited elevated concentrations. Surface water Monitoring Surface water monitoring is carried out in accordance with Schedule 4(i) of Tara‟s IPPCL. A summary of monitoring data is presented in Section 2.11 of this AER (values are based on average concentrations). River and stream samples are taken monthly from 13 locations on the River Boyne, River Blackwater and Yellow River and on the Simonstown and Duog Streams, representing locations upstream and downstream of the TSF, the minesite and the discharge point to the River Boyne. Values indicate no discernable disparity between upstream and downstream samples. For the most part all parameters analysed in surface waters conform to the standards required for both salmonid waters (EC Freshwater Fish Directive (78/656/EEC)) and drinking water. Elevated levels of suspended solids and other elements (iron, manganese and aluminium) were detected in November are likely to be associated with heavy rainfall and flooding during that period. Ambient Air Monitoring Continuous ambient air monitoring is carried out at 6 sampling locations around the minesite and TSF in accordance with IPPCL Schedule 1(v). A summary of monitoring data is presented in Sections 2.9 of this AER. This high volume particulate sampling is performed in accordance with the requirements of Air Quality Standards Regulations SI 244 of 1987 and with the requirements of the Directive (99/30/EC). Dust deposition monitoring is carried out at 12 sampling locations around the minesite and TSF. A summary of monitoring data is presented in Section 2.10 of this AER. Samples are collected on a monthly basis and analysed in accordance with IPPCL Schedule 1(v). Monitoring is performed using Bergerhoff gauges specified in the German Engineering Institute VDI 2119 entitled “Measurement of Dustfall Using the Bergerhoff Instrument (Standard Method)” in accordance with TA Luft Standard. There was no exceedence of emission limit value in 2009. Noise and Vibration Monitoring Continuous vibration monitoring is being carried out at a minimum of 6 locations around the minesite and SWEX area, the number depending on requests from residents. A summary of monitoring data is presented in Section 2.13 of this AER. Environmental Department Non-technical summary

Pollution Emission Register (PER) (Condition No. 2.4)
Prior to 2007 a Pollution Emission Register (PER) Proposal and PER Report was prepared annually by Tara in accordance with IPPC Licence Condition 2.4 and submitted as part of the AER in accordance to the EPER (European Pollution Emissions Register) reporting mechanism. Regulation (EC) No 166/2006 concerning the establishment of a European Pollutant Release and Transfer Register (PRTR) was adopted in 2006. This Regulation, which aims to enhance the availability of information to the general public on the sources and amounts of emissions to air, water and land from European industry is the successor to the EPER reporting mechanism. Now all emissions and waste transfer records are reported via the EPA’s AER / PRTR Emissions Data Reporting Workbook. To prepare for the implementation of this Regulation Tara:
Carried out a review of the PRTR list (91 specified pollutants) and identified those which were / present on the site. Quantified all deliberate, accidental, routine and non-routine releases to air, water and land. Quantified all transfers of hazardous or non-hazardous wastes. Reviewed methods of measurement for air and water pollutants used at Tara.
SECTION 1.1.3
Documentation (Condition 2.5)
Tara’s EMS is made up of a series of components; documentation describes the system and how its components work together. All documents relating to the EMS are ‘controlled’ and maintained within a dedicated electronic Document Management System named Centuri. The system conforms to the strict requirements of the ISO 14001 standard.
SECTION 1.1.4
Corrective Action (Condition 2.6)
The Environmental Department has ‘Corrective Action Procedures’ in place, should an environmental incident occur. These procedures outline the course of action to be taken and the notification procedure to be followed. Responsibility for initiating investigation and corrective action lies with the relevant Department Supervisor. The Environmental Department ensures that correct procedures are followed. Procedures for dealing with environmental incidents are outlined in the Emergency Response Procedures (ERP) which addresses potential emergency situations / events that may arise onsite based on documented experience at Tara and anecdotal information from other, comparable, mining operations. This ERP was designed to prepare for, mitigate, respond to and recover from an emergency. Periodic tests are carried out to ensure effectiveness of procedures in the ERP. Notification procedures are in accordance with IPPC License Condition 4 and the Agency is notified as soon as practicable after an occurrence. A summary report of incidents reported to the Agency and other authorities throughout the year is submitted annually as part of the AER.

Date
Non-Compliance / Incident
Corrective Action
EPA Audit 12/07/09
Waste Storage Was oil was stored in a non-bunded area on a gravelled area (non-compliance with Condition 9.6.1 and 9.6.3)
The two mobile bunds observed have been relocated to the nearby waste oil handling facility. This area is covered and has a concrete base. This measure should eliminate the potential for spillage onto unprotected ground.
EPA Audit 12/07/09
Spill Control No spill control kit was accessible at the waste oil separator compound (noncompliance with Condition 9.6.7). A spill of oil on permeable gravel outside the bund area was noted (non-compliance with Condition 9.5.1)
The area around the waste oil handling area has been cleaned up and a spill kit has been put in place in the waste oil compound. Workers operating in this area have been trained regarding proper waste handling procedures. Adequate supplies of containment booms and oil absorbent materials are kept as stock items.
Bund Integrity Testing The Sulphuric Acid Bund was repaired during 2007 and subject to bund integrity test on 31/10/2007. This test report was found to be deficient (non-compliance with Condition 9.6.1)
Remedial work will be carried out on the sulphuric acid bund and should be complete at the end of the 3Q 2010. Following completion an integrity test will be carried out to satisfy the requirements of the Agency. The small stainless steel containment tank located in a new concrete bund structure (adjacent to the main bund) has not been tested. However, this is designed only to capture any spills and washings that may arise from acid delivery. The level of captured acid is monitored online by the mill central control room operator and emptied automatically, being recycled to the mill. Very small amounts of acid spills are in this tank at any instance in time. Because of buoyancy issues regarding the small lightweight stainless tank it is considered inappropriate to fill this secondary bund with water. All relevant bunds on site have been labeled appropriately and locations indicated on a site plan. A register of these bunds has been compiled and will be forwarded with this AER.

Energy Performance Indicators: Electricity consumption per ton was above target for 2009. Mine power consumption correlates poorly with tonnage and base load has increased possibly due to increased ventilation and water pumping. Mill power consumption was consistently below budget and below 2008 levels until commissioning of the AG mill when low throughput rates had a severe adverse effect. Liters diesel per ton hoisted also ran above target since the middle of the year – this is due to increased underground development activity. The higher unit rate targets set for 2010 reflect planned increases in ventilation and water pumping in the mine and an increase due to the Autogenous Mill.
