Executive Summary Anglo Coal (Drayton Management) Pty Limited (herein after referred to as Drayton) is an open cut coal mine located approximately 13 kilometres from the township of Muswellbrook in the Hunter Valley. Drayton has been in operation since 1983 and has an approved mine life to 2017. This document outlines the environmental and community performance for the 2011 calendar year. This report follows the “Guidelines to the Mining, Rehabilitation and Environmental Management Process” issued by the NSW Department of Primary Industries – Mineral Resources (DPIMR). This report also consolidates all Government reporting requirements for Drayton. Drayton has consent, licence and approval conditions issued by the Department of Planning and Infrastructure (DoPI), Office of Environment and Heritage (OEH) and the Department of Resources and Energy (DRE). During 2011, Drayton continued to operate under Mining Operations Plan 2007-2012. Mining operations in 2011 were focussed in the East Pit, South Pit, Rocky Knob and North Pit (NN) areas. Backfilling of the West Pit area continued during the period with overburden being sourced from the nearby Rocky Knob and South Pit West (SPW) areas. Exploration drilling continued within the current Drayton leases to determine coal quality, quantity and geological aspects to be encountered in future mining areas, in particular focusing in the South Pit East (SPE) and East Pit North (EN) areas. Dust levels remained similar to long term levels during 2011. Gauges within the Antiene area (and in close proximity to all near neighbours) displayed acceptable levels throughout the year. Levels within the Antiene area have remained similar to long term averages. Additionally suspended dust levels were below the NSW OEH goals. A real time PM10 monitor continued to operate in the Antiene area. Approximately 100 hectares of unshaped spoil piles were treated by aerial seeding late in 2011 to reduce dust emissions from Drayton. Weather conditions during 2011 resulted in well above average rainfall. Above average rainfall was received in almost all months with 2011 being the third wettest year on record. However no significant flooding occurred in this region. One offsite water discharge occurred when excessive rain led to the overflow of the Rail Loop dam discharging into a creek leading north off the mining lease. Drayton has since removed a large volume of sediment to increase the capacity of this dam to minimise potential for reoccurrence. Drayton is currently utilising several mine voids to store excess water from current mining operations. Blasting was monitored throughout 2011 with a total of 178 blasts occurring during the year. There was one reportable exceedance during 2011 where a blast was monitored over the 120dB(L) threshold at the de Boer blast monitor. During the year, 18 enquiries were related to Drayton blasting activities. All were discussed with the residents at the time of the incident. Background noise monitoring indicated that noise levels have remained similar to previous years. Drayton continued to conduct attended monitoring throughout 2011 and a real time noise monitoring system continued to operate in the Antiene area. Spontaneous combustion management remains a key environmental focus at Drayton. Monthly inspections and actions are detailed in quarterly reports that are forwarded to the OEH. Areas affected by visible spontaneous combustion remained stable during the year. Community consultation continued throughout 2011 with meetings of Drayton’s Community Consultative Committee (CCC) being held quarterly. Drayton was also involved in a variety of community-based events, such as the Bursting with Energy Expo at the Muswellbrook Show in March 2011. Drayton continues to operate a 24-hour hotline for environmental enquiries. A blasting hotline also allows for neighbours and the general public to access blasting times and the Drayton website is also available where environmental data and reports are publicly available. Waste management continued to improve throughout 2011 with tracking of waste and rebates being recorded. Thiess Services Pty Ltd continued to manage the disposal of waste materials from Drayton. 9.6ha of rehabilitation was completed in January 2011 with a further 20.9 ha completed in December 2011. In total 30.5 ha was completed during the reporting period against the 2011 target of 30.4ha. Annual Environmental Management Report 2011 Drayton Mine

1.1 Consents, Leases and Licences Drayton operates in compliance with a development consent issued under Section 75J of the Environmental st Planning and Assessment Act 1979, on 1 February 2008 and a subsequent modification issued in 2009 to extend a further 8 hectares to the existing approval area. Development consent was also issued in 2000 for the Antiene Joint Rail User Facility. With respect to mining leases, Coal Lease 395 (Mining Act 1973) was granted by the Minister for Mineral th Resources on 24 June 1992. This lease transferred part of Coal Lease 744, comprising approximately 14.5 ha from Bayswater Colliery to Drayton. This lease was renewed in 2008 and now extends to 2029. Section 100 and section 101 applications were granted in 2007 relating to an emplacement area in regard to washery reject material. This approval remained in place for 2011. Drayton’s current Mining Operations Plan was issued in 2006, covering the period 2007 – 2012. Other licences require annual or periodic renewal. A register of current approvals is maintained at Drayton and is updated and circulated as required. Refer to Appendix 1 for specific details.

An Environmental Management Committee (EMC) was instigated in 1995. Members comprise the General Manager, the Senior Leadership Team and the Environment Coordinator, Assistant and Graduate. The committee meets on a monthly basis to discuss environmental performance and community issues, and to provide guidance for environmental management to the organisation. All other departments within the company are also responsible for specific aspects of environmental management within their work areas under the advice of the SHE Department. The Technical Services department is responsible for the integration of environmental management into mine planning in addition to in-pit activities. This department is responsible for ensuring that rehabilitation is scheduled and, along with the Mining Operations department, that targets are achieved. The Engineering and Maintenance area is responsible for the minimisation of environment impacts when maintenance works are undertaken. The Environment Coordinator, in consultation with the Technical Services department and utilising both mining personnel and contractors, coordinates all mine site rehabilitation. Commercial aspects of environmental management are taken into consideration through the Commercial Manager’s participation in the EMC and for the provision of rehabilitation in the accounting field. All employees and contractors are also accountable for their environmental performance and employees have environmental requirements set within their position descriptions. In summary, environmental performance is the responsibility of all Drayton employees however it is the responsibility of the SHE department to measure, monitor and advise on this performance. This is achieved with the cooperation of all other departments within the company. Environmental performance is continually reviewed by the EMC, and environmental considerations are taken into account in all areas of the operation.

1.5 Corporate Environmental Goals and Policies The Drayton operation is part of leading global mining company Anglo American’s Metallurgical Coal business. Drayton is operated by Anglo Coal (Drayton Management) Pty Limited which is a wholly owned subsidiary of Anglo American Metallurgical Coal Pty limited. Anglo American’s philosophy holds that all employees are accountable for environmental protection, appropriate to their particular job function. Environmental performance lies with line management, from Chief Executive Officer to every level in the organisation. Responsibilities and accountabilities are included in job position descriptions and consideration of environmental performance forms a part of the performance appraisal of all staff. Drayton is certified to Anglo American’s Metallurgical Coal business unit Safety, Health and Environment Management System (SHEMS) to both ISO 14001 for its environmental management practices and AS4801 for health and safety. Each year, annual business plans are completed detailing ongoing commitments to safety, health and environment (SHE) and setting goals for various aspects of SHE management.

2 Operations during the Reporting Period Drayton produces coal suitable for electricity generation, cement manufacture and industrial processes. It has high specific energy, low ash and medium sulphur levels. All coal produced is marketed as product. Saleable coal produced in 2011 was 4.527 million tonnes. This total also consisted of a portion of semi soft coal. Mining operations in 2011 focused on the East Pit, Rocky Knob, South Pit (SS) area and North Pit (NN) areas. The West Pit area has now been finalised under a sub lease agreement with Mt Arthur Coal.

2.1 Exploration A total of 147 boreholes were drilled during the 2011 exploration programme. All of these boreholes were drilled within Coal Lease 229 and Mining Lease 1531. Of these, 14 were 96mm HQ3 cored boreholes. 133 boreholes were non-cored (Rotary). Eight HQ3 boreholes (including 2 re-drills) were positioned over a broad grid in the East-North (EN) proposed pit area to give coal quality, structural and geotechnical data. An additional borehole was drilled in EN for gas desorption testing on all mining sections. Further to exploration in EN a core program of 5 boreholes (including 1 re-drill) was conducted in and around the vicinity of South Pit East (SPE). Of these, 4 were for coal quality, structural and geotechnical data and the remaining hole was drilled solely for reactive ground analysis. Non-cored boreholes are located over the NN, EN and SPE areas and primarily targeted lithology/stratigraphy and structure for further delineation of mining areas. A program was conducted in conjunction with Mt Arthur Coal to the east of NN pit where a series of 11 boreholes were drilled to define resource extent and structure.

2.2 Land Preparation During 2011, approximately 12 hectares were cleared of topsoil in preparation for mining activities. This was predominantly in the Rocky Knob, EN and NN areas. Topsoil from these areas was respread over rehabilitated areas as well as stockpiled. Annual Environmental Management Report 2011 Drayton Mine

10 of 171

2.3 Construction 2011 saw the completed construction of a fines plant within the existing Coal Handling Plant (CHP). This plant was commissioned during the first quarter of 2011. No other permanent structures were constructed in 2011.

2.4 Mining 2.4.1 Estimated Mine Life At the end of 2011 and under the current consent approval, the estimated mine life for Drayton extends to 2017. During 2011 an exploration program continued to determine Drayton’s potential mine life and to confirm resources for the remainder of mine life. The total mine plan and additional resources are 40,700 st million tonnes as at 31 December 2011. This figure comprises of both resources and reserves

2.4.2 Recovery / Dilution The current approvals have Drayton’s long term mine annual production rate remaining around 5 million tonnes and decreasing to 3 million tonnes in about 2016-2017, however upon completion of exploration program and review of mining options, this will ultimately change in the forthcoming years. Coal is mined selectively, with blending undertaken at Drayton’s Coal Handling Plant (CHP). The geological complexity of the Drayton deposit has provided an ongoing challenge for mining. Folding, faulting and steep dips occur extensively. Whilst upper seam interburden is predominantly softer shales and siltstones, the Balmoral sandstone, above the lowest seam group, is a massive formation of inert competent rock. Mining operations have centered on the North, South and East Pits, with mining occurring in four main areas: northern end of the north pit (NN) northern end of the east pit (EN), south-eastern strips (ES, SP) and the Rocky Knob area. During the reporting period mining of the ES strips was completed. Mining in the NN area, north of the existing East Pit, has continued throughout 2011 with operations extending in a northerly direction. Mining in the Rocky Knob area also continued during 2011 with the southern end of the area being excavated and coal progressively being mined.

2.4.3 Overburden Handling Overburden and parting material at Drayton is removed by excavator and truck fleet or by the dragline. All overburden and parting material are removed to tips, located within the previously mined areas. Placement of this material follows the guidelines in Drayton’s Spontaneous Combustion Management Plan. Details mining statistics for 2011 are shown in Table 3.

2.5 Mineral Processing All mineral processing at Drayton is undertaken through the Drayton Coal Handling Plant (CHP). This facility comprises of a series of small washery, fines plant, crushers, two stackers, two-bucket wheel reclaimers and a series of overland conveyor belts. Coal leaves Drayton by either rail, through the Drayton Rail Load Out facility and Antiene Rail Spur for export coal or by overland conveyor to the Bayswater Power Station for domestic supply. During the reporting period Drayton ceased conveying coal to Bayswater Power Station with all coal now railed from site.

2.5.1 Saleable Coal Production At Drayton all coal mined is saleable coal. Coal is selectively mined and blended to meet market specifications. In 2011, 4.527 million tonnes saleable coal was produced, of which 0.547 million tonnes went to the domestic market and 3.903 million tonnes went to the export market.

2.5.2 Changes or Additions to Processes or Facilities during Reporting Period During 2011 a coal fines plant within the existing coal handling plant was commissioned. This plant has provided Drayton with greater scope to market its coal. Tailings disposal continued into the BW void and will continue until a final void has been established in the East Pit and approvals for the utilisation of this area have been obtained.

2.5.3 Changes in Product Transport During the reporting period Drayton ceased providing coal to Bayswater Power Station resulting in coal conveyed ceasing. No coal is transported by road. All export coal produced at Drayton is transported by rail to the port of Newcastle.

2.6 Waste Management 2.6.1 Waste Management Drayton’s waste management objective involves increasing the knowledge and training of staff and contractors to minimise production of waste streams and maximise utilisation of identified recycling and reuse options. Management strategies are in place for each major waste stream relevant to key work areas. Drayton seeks to minimise the risk of safety, health and environmental incidents and liabilities that may be caused by waste generated or stored onsite by operating in accordance with the site’s Waste Management Procedure, which incorporates all major waste streams. A waste management contract currently exists with Thiess Services providing a complete, integrated waste management service. Monthly inventories and reports ensure all waste movements are documented. Major waste streams include oil, batteries, grease, empty drums, cardboard bales, wooden pallets, and mixed recyclables (including paper and aluminium cans). Any spills that occur within waste collection areas are contained within the bunds for spill control, and drain into Drayton’s pollution control system. Table 5 indicates the total waste collection for 2011.

2.6.2 Recycling Initiatives Where possible waste items are recycled by Original Equipment Manufacturers or certified contractors. Machine batteries, mobile phone and radio batteries, waste oil, grease, empty drums, aluminium cans and scrap metal are removed from site by the Waste Contractor and are recycled. Planet Ark removes used printer cartridges. Reimbursements are received for waste oil, batteries and metal waste streams.

2.6.3 Oil and Grease Containment and Disposal Controls in place for the management of oil and grease include the following: 

Both fixed and mobile evacuation systems are used to manage lube and services within the workshop and in pit. A registered contractor for recycling collects this waste on a regular basis from the collection tank.



Field service trucks are fitted with evacuation systems and storage tanks for the evacuation of waste from plant and equipment located in the field. Evacuated wastes are then transferred to the workshop evacuation system.



An oil and grease interception dam is located downstream of the workshop area. This interceptor dam is designed to collect all oily flows from the surrounding area, and to minimise any oil, floating debris, grease and silt from being released into the mine water dam below.



Empty resealable drums are available in the store for the collection and storage of waste grease. When full, these drums are collected by Thiess. If reasonably uncontaminated, the grease is recycled, as well as the drums. If the grease is contaminated with items such as rags and gloves, the grease is incinerated.

2.6.4 Sewerage Treatment / Disposal Drayton's sewerage treatment plant collects and treats on-site effluent. The treated effluent is then collected in two settlement ponds, and the overflow is pumped to an area of rehabilitation on the East Tip.

This includes septic tanks that exist in other areas of the mine such as the CHP and crib huts not connected to the onsite treatment station. A licensed contractor collects these and the effluent is pumped back into the on-site treatment plant. A total of 578,000 litres of effluent was collected during 2011.

2.6.5 Rubbish Disposal Domestic rubbish from the site is emptied into collection bins provided by the Waste Contractor. This rubbish is transported to and deposited in the Muswellbrook Waste Management Facility. During 2011, 380 tonnes of domestic rubbish was removed from site and deposited in the Muswellbrook Waste Management Facility.

2.7 Ore and Product Stockpiles All coal produced at Drayton passes through Drayton’s Coal Handling Plant (CHP). The coal is crushed so that 100% of the coal passes 50mm and 95% passes 38mm, and then it is stacked on one of four stockpiles. Each stockpile has a capacity of approximately 80,000 tonnes. Coal is blended on the stockpiles to meet market specifications. A ROM stockpile is also located adjacent to the CHP dump hopper, which is capable of storing up to 200,000 tonnes. This additional storage allows for the blending of a range of coal types from a number of coal seams. Total reject produced in 2011 was 774,000 tonnes. Tailings disposal accumulated to 1,325,426 cubic metres.

2.8 Water Management 2.8.1 Water Use The water management flow path is illustrated in Figure 1. Drayton had two final voids to the west of the mine for excess water storage in 2011, the SW13 and BW voids. Another final void, the East Pit South (ES) void became available for excess water storage during 2011 at the completion of mining. A highwall pump is installed on the SW13 void to transfer water back to the operations via Savoy Dam (1609) and a series of small holding dams. These dams, to the south of the mining operations, are connected in series to the ES void and the Access Road Dam (2081). This main ring line is capable of moving mine water both into and out of the storage locations allowing flexible water management depending on usage, rainfall and fluctuations in storage volumes. Water is applied in the pit on the haul roads and around the workshop to minimise airborne dust. During 2011, approximately 600ML of mine water was utilised for haul road dust suppression. Water from Savoy Dam can be pumped to the West Pit truck fill point for this purpose. ES void water is pumped to the Industrial Dam (1969) from where it is used for haul road dust suppression via the East Pit truck fill point or may be transferred to the Access Road Dam (2081). Water from the Access Road Dam (2081) is used to supply industrial water to the workshop and wash down areas. The Coal Handling Plant (CHP) also uses a large percentage of the water from 2081 for the Coal Treatment Unit (CTU) which was upgraded during 2011 and dust suppression on coal stockpiles and conveyors. The BW void is not equipped for the return of mine water to the Drayton water management system. This void is only a recipient of water and was the recipient of Drayton tailings during 2011. During 2011, water consumption was approximately 2595ML. Of the total consumption, 575ML consisted of industrial usage mainly through washdown in the workshop and truck wash bays and 600ML was sprayed onto haul roads for dust suppression purposes. Approximately 1015ML was used by the CHP to process coal through the upgraded Coal Treatment Unit (CTU), for washdown and in CHP dust suppression systems. Some of the CHP water consumed was lost through tailings slurry pumping and flushing of the newly commissioned tailings line from the CTU.


16 of 171

Drayton’s total water storage capacity is approximately 8153ML, of which 1653ML capacity is in established dams and 6500ML is available in disused voids. Of the 6500ML available in void storage, approximately 3900ML is accounted for by the ES void which became available during 2011 at the end of mining in East Pit South. This storage is currently holding only water but is planned as a tailings emplacement area where both water and tailings will be stored. Water will be reclaimed from this void for recycling through industrial use and coal processing. Water storage levels in dams and voids are surveyed each month. At the end of 2011, approximately 922ML was being stored in established dams and 1672ML in pit voids. This equates to approximately 56 percent of available dam storage capacity and approximately 26 percent of available void storage capacity. Drayton’s water storage at December 2011 is shown in Table 6. Some dams exist principally for the prevention of discharge and as sedimentation structures for runoff. Dam 1895 (Far East Tip Dam) controls runoff from the Far East Tip, a rehabilitated, out of pit overburden dump. This dam has a capacity of approximately 130ML and has no connection with mining activities. The dam capacity is therefore not included in the overall site storage capacity. The dam is currently being monitored for quality on a monthly basis. All water quality monitoring results have been included in Appendix 2.1. Drayton is a credit holder in the Hunter River Salinity Trading Scheme (HRSTS). As Drayton’s licence conditions do not permit mine water discharge, direct participation in the water releases did not occur in 2011. During September 2011, Drayton made a trade of HRSTS credits with Macquarie Generation. Potable water is supplied for domestic use by a pipeline from Muswellbrook Shire Council.

Drayton currently has seven Water Licences issued by the NSW Office of Water. Most relate to piezometers which are for monitoring purposes only. One allows groundwater extraction of up to 985ML per annum from the mining operations due to ground water inflow. Estimated groundwater inflow to active workings in North Pit, East Pit and South Pit does not exceed 955ML per annum. Pit water extracted from Drayton’s operation is a combination of both ground water and surface runoff from the areas within the pit during periods of rainfall. Dam 2114, located within the rail loop acts as both a transfer dam and collects runoff from the CHP and Rail Loadout Facilities. A water discharge event occurred from the Rail Loop Dam (2114) during June 2011. The uncontrolled event occurred during a period of high intensity rainfall when approximately 100 millimetres of rainfall fell within a 48 hour period. The incident was reported to the Office of Environment and Heritage (OEH) and the Department of Planning and Infrastructure (DoPI). The DoPI conducted an inspection of the Rail Loop Dam in early July 2011. Drayton received a letter from the DoPI and an instruction to perform desilting work on the dam to maintain maximum capacity. The de-silting was conducted in September and October 2011.

Final landforms of the East, North and South Pits will ultimately result on final voids. These proposed structures are detailed in the Mining Operations Plan and will be based on the following criteria: 

All exposed coal seams in final highwalls and endwalls will be covered with a seal of inert material to a height of two metres above the roof of the coal seam, to prevent spontaneous combustion;



All final walls will have an overall angle of 37 degrees to maintain long term stability;



Low walls leading into final voids will be rehabilitated to steep slopes of 18 degrees with five metre wide berms every 15 vertical metres;



A four metre high safety berm will be established all around the final highwalls and endwalls to prevent accidental entry into the voids;



Contour drains will be constructed around voids to prevent fresh water run-off from undisturbed ground entering the voids; and



Final voids will be used to capture run-off from rehabilitated areas until run-off water quality has been proven to be of suitable quality to discharge into natural catchments.

Whilst the final outcome for the ultimate use of final voids has not been fully determined as yet, Drayton has entered into discussion with Macquarie Generation over the potential use of an east pit void for additional ash disposal area for Liddell power station at the end of mine life for Drayton. Other uses of final voids may consist of the following: 

Tailings disposal;



Out-of-pit emplacement areas for surrounding mines;



Residue disposal areas for surrounding mines;



Ash disposal for local power stations; and



Garbage disposal areas for local communities.

During 2011, Drayton continued to utilise the SW13 void, located in the West Pit for water storage. Drayton utilise this water for dust suppression in the Rocky Knob and East Pit mining areas and the West Pit emplacement area. This void is part of the sub lease arrangement with Mt Arthur Coal, with Drayton retaining the rights to store and extract up to 1000ML water from the void for the remainder of Drayton’s mine life. At the completion of Drayton mining operations, Mt Arthur Coal will be responsible for emplacement of material, final landform design and creation and final rehabilitation of this void.

2.9 Hazardous Material Management 2.9.1 Status of Licences Drayton’s Dangerous Goods licence was renewed during 2011. The applicable licences and registrations are listed in Table 7.

2.9.2 Fuel Containment Fuel containment at Drayton consists of a series of above ground storage tanks. The major containment for diesel is in a Class C1 above ground tank with a capacity of 860,000 litres. In addition to this, three other above ground tanks are located around the mine, each being Class C1 and capacities of 27,000 litres and two each of 110,000 litres All permanent fuel containment areas are earth bunded. These tanks are currently listed under Drayton’s licence for keeping dangerous goods (licence number 35/019387).

2.9.3 Inventory of Material Safety Data Sheets All chemicals used, or proposed to be used, onsite are checked for their safety and environmental effects by the SHE department. All chemical usage must be approved of by the SHE Department prior to its use on site. For each chemical a Material Safety Data Sheet (MSDS) is maintained in a central register. All contractors working with chemicals must also carry the relevant MSDS. All work is required to be carried out in accordance with the MSDS advice. At Drayton, the ChemAlert database supplied and managed by Risk Management Technologies is utilised to assist with chemical management. This system contains MSDS for all chemicals used on site. In addition, extra information is included in the database that is not necessarily required by law. This information includes environmental hazards associated with the use of each chemical, and the necessary measures to control these hazards.

2.10 Other Infrastructure Management The Antiene Joint Rail User facility has specific conditions of consent. These are detailed in Section 7.1 of this report.

2.11 Environmental Risk Drayton has assessed the risk associated with the primary aspects of mining activities. Table 7Table 8 shows the primary aspects of mining rated against the Anglo American Risk Matrix (Appendix 5).

3.21.3 Interpretation and Review of Results Similar weather conditions prevailed in 2011 as occurred in 2010. Above average rainfall was received in seven months during 2011. Maximum rainfall occurring over a 24 hours period was 59.6mm occurring in June 2011. June and November 2011 both showed much higher rainfall (by 89.6mm and 93.2mm respectively) than in the previous year. July 2011 was the opposite with 78.6mm less rain than the previous year. During 2011 a total of 978.2mm of rainfall was recorded which is the highest amount of rain received in a year since the start of rainfall recording at Drayton in 1981. Throughout the year, the total number of wet days was 151 compared to 169 days affected by rainfall greater than 0.2mm in 2010. Figure 12 illustrates 2011 rainfall compared with historical rainfall patterns. November 2011 was the wettest November on record for Drayton. Annual Environmental Management Report 2011 Drayton Mine

62 of 171

Temperatures in 2011 followed similar results in recent years with the temperature range being 0.2 to 42.3°C. Only slightly higher monthly temperatures in summer separated the historical temperature trend to 2011. Overall temperatures were akin to long term averages. Wind patterns for 2011 were generally similar to previous years. Wind speeds remained similar to 2010 levels below 8m/sec which was historically down as in previous years winds were experienced in excess of 10m/sec during some periods of the year. Maximum wind speed recorded during 2011 was 18.72m/sec in July. Wind direction generally followed normal trends with significant E-SE winds during the period October through to April, W-NE for the remainder for the year.

4 Community Relations Drayton has an ongoing close association with near neighbours. The SHE Manager and the Environment Coordinator have regular contact with the local residents to discuss environmental, safety, exploration and operational issues. All local residents are encouraged to contact Drayton if they have any concerns or questions relating to the Drayton mining operation. Information is also mailed or hand delivered to local residents regarding developments occurring at Drayton. Drayton has an active Community Consultative Committee, which has been in operation in excess of 15 years. This forum meets on a quarterly basis to discuss environmental and operational issues.

4.1 Environmental Complaints Drayton has a documented process for receiving enquiries relating to environmental issues, whether they relate to Drayton specifically or not. All enquiries are investigated and the enquirer is informed whether there was any Drayton activity at the time stated relating to the incident, and if so, informed of the results of any investigation when they became available, and the issues discussed. If the enquirer wishes to have the issue classed as a complaint, it is recorded as a complaint rather than an enquiry. Drayton uses a real time noise monitor located in the Antiene area to investigate all noise complaints and blast monitors to investigate the results of blasting. During 2011, 47 enquiries were received. Of these, 8 did not relate to Drayton, 2 were regional issues. Of the remaining enquiries, 18 related to blasting, 7 to Spontaneous Combustion odours, 17 to noise, two regarding lack of communication and one to a enquiry regarding the potential sale of a property. Of the 47 enquires that were received, 8 were specific to rail activity noise. Table 26 lists all enquiries received by Drayton during 2011.

4.2 Community Liaison The Drayton Community Consultation Committee (CCC) met on four occasions during the year, in February, May, August and November. A number of issues were discussed during the year at the CCC meetings. These issues included Drayton’s environmental action plan, rehabilitation, current and future mine development and assessment process, blasting and rail spur issues. The 24-hour environmental contact line remained operational during 2011. The phone number is 1800 814 195, and is available to the public for reporting of environmental incidents. This is also advertised in local newspapers each month. Drayton’s environmental website continued to host minutes of CCC meeting, quarterly performance data, and displaying environmental approvals and management plans as they are approved. A Joint Community Consultative Committee also operates between Drayton’s constituent CCC members, together with Mt Arthur Coal’s CCC members. This forum met on two occasions during 2011, discussing issues relating to the joint rail spur development. Issues discussed included environmental performance, monitoring data and enquiries.

4.3 Social / Economic Contributions and Achievements During 2011, 35 employees were awarded service awards. Two received ten year awards, one received a 20 year award, thirty one received 25 year awards and one employee reached 30 years of service. Drayton continued its association with educational groups in 2011. Two university mining engineering students were employed over the summer vacation period of 2011/2012. During 2011, Drayton again took part in a Bursting with Energy Expo as a component of the local Muswellbrook Agricultural Show. This was held over two days with presentations, giveaways and mining representatives being available to address enquiries. Drayton Mine has a community support policy, under which all requests for donations and sponsorships are considered in a consistent manner, the main focus being on youth in the local community. In 2011 $22,000 was donated to local community groups, charities, junior sporting clubs and schools as well as organisations such as the Westpac Rescue Helicopter. Drayton has a community engagement plan as required by Anglo American. This details company policy of engaging with community groups and communication measures to be undertaken.

5 Rehabilitation (This AEMR Period) The main objective of mine rehabilitation at Drayton is to create a landform which is compatible with the surrounding countryside, is stable in the long term and which is capable of a productive form of land use. This future landform is also designed to align to the general principles of the NSW Department of Resources and Energy - Mineral Resources Synoptic Plan of Integrated Landscapes with respect to the creation of wildlife and habitat corridors. The traditional use of the area has been beef cattle grazing, so maintenance of grazing capacity is one objective. Trees are also an important part of the existing ecosystem and biodiversity and as such the establishment of trees native to the region is another objective. Both of these goals are compatible and attainment of these goals will result in land that has good grazing potential and high wildlife amenity.

5.1 Buildings During 2011, construction was completed on a fines plant within the existing coal handling plant (CHP) preparation area. No additional buildings were constructed.

5.2 Rehabilitation of Disturbed Land Drayton had a target of 30.4ha to be rehabilitated in 2011. A total of 30.5ha was completed and comprised of 9.6ha in January and 20.9ha in December. The areas that were rehabilitated in 2011 were on the northern, southern and eastern sides of the Great North Tip. These areas are highlighted on Figure 18. Table 27 gives a summary of mining areas located at Drayton for 2011. A further 12.3 hectares was bulk shaped and topsoiled ready for seeding during 2012. No maintenance of rehabilitated area was required during 2011. All areas rehabilitated during 2011 were sown with pasture species. Fertiliser was applied at the time of seeding and excellent groundcover has been established. Stability of slopes and condition of contour banks are assessed as part of regular site inspections. No maintenance was required to erosion control measures in 2011. The 9.6 hectares of rehabilitation scheduled for 2010 was completed in January 2011. The area was spread with a mixture of pasture species and fertiliser. The area was prepared for rehabilitation during 2010 with topsoil spread and contour banks installed to prevent erosion. With consistent rainfall received throughout 2011, a high level of vegetation cover has established, creating a stable slope. No maintenance was needed during 2011. Areas rehabilitated during the reporting period were prepared in accordance with the Drayton Rehabilitation and Offset Management Plan and the Spontaneous Combustion Management Plan. These areas where bulk shaped then capped with a 2 meter layer of inert material to minimise the risk of spontaneous combustion. Topsoil was spread over the areas with a minimum coverage of 10cm. Contour drain construction and seeding works were conducted by NSW Soil Conservation Services.

5.3 Rehabilitation Trials and Research No rehabilitation trials or research was conducted in 2011.

5.4 Further Development of the Final Rehabilitation Plan 5.4.1 Synoptic Plan of Rehabilitation Performance Drayton continues to follow the general principles of our mining operations plan. A total area of 672 hectares remains disturbed with a total of 576 hectares being rehabilitated. Due to the incidents of spontaneous combustion, inert capping is applied in areas of rehabilitation that are of risk of an outbreak of spontaneous combustion. Erosion control measures are incorporated into final rehabilitation works where appropriate. This strategy for rehabilitation shall continue using similar successful methods.

5.4.2 Review of Rehabilitation Monitoring and Performance Rehabilitation during 2011 did not follow exactly as predicted in the Mining Operations Plan and Drayton’s business plan. At the end of the reporting period 30.5ha of rehabilitation was completed. Of the total area rehabilitated, 9.6ha was planned for 2010 although was completed in January 2011. A weed control program continued during 2011 with Prickly Pear and St Johns Wort being the primary targets treated. This program will continue throughout 2012.

6 Activities Proposed In the Next AEMR Period 6.1 Environmental Performance Environmental targets for 2012 include:  Maintain full compliance with environmental legislation;  Nil discharge of mine water; All blasts to be less than 5 mm/sec ground vibration and 115 dB(L) at the nearest residence;  Dust emissions to be below the statutory limits of 4g/m2.month and 50 g/m3 Total Suspended Particulates at the boundaries;  Noise emissions to be below statutory requirements;  Reduction in spontaneous combustion emissions by continued improvement in application of the spontaneous combustion management plan;  Continuation of the Community Consultative Committees;  Continuation of the waste management plan and continued improvement in the application of the waste management practices;  Continuous improvement of the documentation associated with the Environmental Management System;  Maintain compliance with ISO14000 systems Targets and Objectives for the operation of the Antiene Rail Loop and Drayton Rail Spur will remain consistent with those detailed for the Drayton mining operation.  Conduct 18ha of rehabilitation.

7 Additional Information 7.1 Antiene Joint Rail User Facility As condition 8.1 of DUAP development consent S99/01070 states, the following additional information is supplied in relation to environmental management of the Drayton Rail Loop and Antiene Rail Spur development. Some aspects have been specifically addressed within the core of this report, however some aspects lies outside the bounds of the format this report follows. This section therefore addresses those specific areas not previously covered in this AEMR. st

st

This report relates to the period from 1 January 2011 – 31 December 2011.

7.1.1 Review of effectiveness of environmental management During 2011, general environmental monitoring continued with regard to both Drayton’s mining operation and the use of the Drayton Rail Loop Facility. This data has been discussed in detail in relevant sections of this report. A joint Community Consultative Committee held two scheduled meetings during 2011 each comprising both the Drayton Community Consultative Committee and the Mt Arthur Coal Community Consultative Committee where the environmental performance of the rail spur is discussed and reviewed at length, together with any environmental enquiries, and other issues, which may have been raised. Drayton received 8 enquiries regarding rail activity during 2011. These were initially indicated in Table 26 and are sub listed in Table 28 below.

Blast and train noise

Email recieved from DoP on 7th Dec from de Boer regarding a Drayton blast at 3pm on Thur 1st Dec 2011 which was reported to be loud and shook the house. Complaint also made about train noise from 9am on Sat 3rd Dec and from 2:20am on Sun 4th Dec. Complaint investigated. Reponse sent to DoP via email on 8th Dec. Results of blast at 3:15pm on Thur 1st were within limits. Drayton train loading at 9am on 3rd Dec but no train at 2:20am on 4th Dec. Noise levels within limits on both occasions.

21/12/2011

Lot 27

Train noise

Email received from DoP regarding train noise. Trains were recorded by DoP Ben Harrison. Noise was investigated and found to be within compliance limits.

Several of these related to train movements from both Drayton and Mt Arthur Coal. On three occasions, Drayton did not have any rail activity occurring. During the reporting period the department of Planning and Infrastructure requested that an independent audit of a near neighbours property identified whilst noise was compliant with the relevant Drayton consent conditions, noise was elevated.

7.1.2 Trends of monitoring results over life of the project Trend analyses of both noise and air quality have been discussed within this report. Appendix 7 illustrates longer-term trends in both noise and dust monitoring. With regard to noise monitoring, trends over a period of 1998 – 2011 show trends in Leq are reducing. It must be noted that these figures encompass all noise emissions, which largely are non mine related. Major influences include New England Highway, Thomas Mitchell Drive, birds, wind and dogs. Trend analysis for both data sets indicates stable or lessening noise levels. With regard to dust emissions, data sets studied throughout the Antiene rural subdivision, generally indicate no increase in dust emissions is evident over a period of in excess of 20 years in some instances. Therefore mining activity and rail influences from the Drayton Antiene Rail Spur have not indicated any significant increase in either parameter within the local community.

7.1.3 Variations in relation to approvals There have been no variations to Drayton approvals relating the rail facility during this period.

7.1.4 Environmental management targets and strategies Environmental targets and strategies will remain to be those detailed in the Environment Management Plans. 

Adhere to all conditions as set out in development consent;



Ensure all monitoring is undertaken as per EMP and consent conditions;



Ensure all enquiries are dealt with promptly and efficiently;



Ensure all reporting requirements are met within the required timeframe;



Ensure, if required, the any requirements outside of this consent, as directed by the Director General are undertaken; and



Ensure active community consultation continues on a regular basis.

7.1.5 Coal Haulage Report A coal haulage reports are required under condition 6.1 (e) on a six monthly basis. These were reported to Department of Planning at the appropriate time, with a summary report being contained in Appendix 6.

7.2 Dams Safety Committee requirements The Liddell Ash Dam Levee (ADL) was constructed to protect the Drayton Mining Operation from ash and water entering the mine workings. During 2011, the NSW Dams Safety Committee (DSC) issued Drayton with new requirements for monitoring and reporting regarding the ADL.

The new conditions require Drayton to provide monthly reports on the ADL in place of the previously required quarterly reporting. The monthly reports contain information regarding the condition of the ADL and monitoring results for rainfall, seepage and blast operations near the ADL wall.

The DSC set vibration limit for blasting is 20mm/sec. During 2011, no blast exceeded the 20mm/sec limit. The current DSC requirements for monitoring and reporting of the ADL include:  Annual independent Type 2 engineering assessment;  Tri-weekly inspections conducted by a competent person;  Annual review of the Ash Dam Management System;  Appoint a DSC Liaison Officer;  Inspect after each blast in the notification area;  Report significant changes in seepage to DSC immediately;  Report blast vibrations in excess of 20mm/sec to DSC immediately; and  Provide a monthly report on: o seepage o ash deposition status o blast monitoring results within the notification area o mining face positions o compliance statement The Drayton Access Road Dam (2081) is also DSC prescribed dam. This dam is a 13 metre high significant consequence category dam. A Type 3 surveillance inspection is conducted every five years and results reported to the DSC. The last Type 3 surveillance report for this dam was submitted to the DSC in September 2010. The next report is due in June 2015.
