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.


7 of 171

The Drayton Environmental Management System (EMS) remains accredited to ISO 14001. Recertification will again be sought in 2012.

In summary, 2011 was a good year for Drayton in its environmental performance and community relations. Environment and community shall remain a key component of the operation as mining progresses in 2012. Introduction

1.4 Site Personnel Responsible For Mining, Rehabilitation and the Environment

The Safety, Health & Environment (SHE) Department is responsible for coordinating and facilitating environmental management and community issues on site. The department comprises of a SHE Manager, an Environment Coordinator, Environmental Assistant, Environmental Graduate and two Occupational Health and Safety (OHS) Officers. The SHE Manager, as a member of the Senior Leadership Team (SLT), reports directly to the General Manager on the implementation of policies and procedures across the site.

The Environment Coordinator is responsible for the recording, interpretation, and communication and reporting of environmental information gathered by Drayton’s monitoring programmes in addition to community based activities. The Environment Coordinator is also responsible for advising on mine-site rehabilitation, research programs, corporate reporting and other environmental issues.


9 of 171

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.

1.6 Employment Status and Demography

At the end of 2011 there were 445 permanent employees at Drayton, an increase of 35 employees from 2010. Drayton also engages the services of contractors to assist in some areas of the operation.

Table 2 indicates the origin of the permanent workforce at Drayton as at the 31st December 2011.

TOTAL 445

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.

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.


11 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 million tonnes as at 31

st 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.


16 of 171

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.


17 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 de-silting work on the dam to maintain maximum capacity. The de-silting was conducted in September and October 2011.

Figure 1: Water Management Flow Diagram Final Void


19 of 171

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

2.9.2 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 Environmental Management and Performance

Environmental monitoring is a key component of Drayton’s operation. Monitoring undertaken includes surface water quality; ground water; air quality; noise; blasting; and meteorology. All monitoring follows the appropriate Australian Standard, with collection of samples by site personnel and analysis of water and dust fallout samples being assessed by an independent laboratory.

(Dust is assessed as insoluble solids as defined in AS 3580.10.1-2003)

Current dust control management strategies include:

Clearing and topsoil stripping is restricted to a single strip ahead of mining;

Overburden drills are equipped with equipment to minimise dust generation;

Water tankers are operated on site for haul road dust suppression;

Dragline operations are conducted to minimise dumping height so there is minimal freefall of material;

Blasting of overburden is carried out using gravel stemming or drill cuttings which contains the blast energy in the ground and minimises dust;

The Coal Handling Plant is equipped with dust suppression sprays at the dump hopper and transfer points as well as coal stockpiles;


24 of 171

Rehabilitation of mining areas is progressive and follows the open cut approval plans to minimise exposed overburden areas; and

Implemented Dust Management Plan.

During December 2011, an amendment to the Drayton EPL was received from the OEH. The Amendment requires the introduction of a Pollution Reduction Program (PRP) which will take the form of a report ranking the top four mining activities that currently generate the most particulate matter. The PRP report will:

Estimate baseline emissions from the four mining activities;

Estimate possible reductions in emissions from implementing “best practice” measures;

Assess the practicality of these measures; and

Propose a timetable for the implementation of any practical measures.

The PRP report will be submitted to the OEH by June 2012.

On 20th December 2011, a trial of aerial seeding was conducted on the spoils in areas where spoils are

expected to be inactive for a period of several months, and in areas with very steep grades along haul roads. The purpose of the trial was to assess this best practice management technique for effective dust control on temporarily inactive spoil materials. Germination and establishment of cover will be assessed through visual monitoring during 2012. The trial is expected to help determine the best areas and types of spoil materials where this temporary dust control measure can be effective.

3.1.2 Dust Monitoring Results

3.1.2.1 Fallout Gauges Dust depositional gauges have been in operation for the duration of the life of the mine. Drayton’s depositional gauges that are used for compliance are situated in the Antiene area to reflect the mines near neighbours. Monitoring conducted during 2011 in the Antiene area included 8 dust gauges which were sampled on a monthly basis to the north of the lease boundary and in the vicinity of the residential areas around the mine.

The location of the gauges is indicated in Figure 2.

The dust gauges and measurement conform to the AS 3580.10.1 - 2003 - Methods 10.1 - Determination of Particulates - Deposited matter - Gravimetric Method. Samples are collected at the beginning of each calendar month according to AS 2724.5(1987). The samples are analysed by an independent laboratory for total solids, insoluble solids, ash residue and combustible matter. A field observational assessment is also noted as to possible contamination of samples.

Table 10 summarises the average monthly deposition rate over the year’s results of total solids, insoluble solids, ash and combustible matter. Due to the design of dust depositional gauges, they are regularly subject to high levels of contamination. Details relating to each individual gauge on a monthly basis are outlined in Appendix 2.3.

3.1.2.2 Total Suspended Particulates

Total Suspended Particulates (TSP) is measured using high volume air samplers in accordance with AS 2724.3 – 1984: Particulate Matter – Determination of Total Suspended Particulates (TSP), High Volume Sampler Gravimetric Method.

Drayton operates two high volume air samplers at locations indicated in Figure 7. Each sampler is operated according to the monitoring programme requirements of the OEH. Both samplers were upgraded with replacement monitors on 19

th December 2011. The Met Station monitor is located onsite in the CHP area

and used to indicate TSP levels onsite whereas the Lot 22 monitor is located offsite and is used for compliance purposes reflecting TSP levels at near neighbours. The results for the year are in Appendix 2.5, the summarised results are in Table 11 and the year results and historical results are in Figure 3 and Figure 4.

3.1.2.3 Real Time PM10 Monitoring

Commissioned in late 2009, Drayton’s Tapered Element Oscillating Microbalance (TEOM) continuously monitors ambient particulates with diameter less than ten microns (PM10). This monitor is located between Drayton’s mining operations and near neighbours boundaries (refer to Figure 7) and used to indicate real time dust levels between the operation and near residents.

TEOM data capture for 2011 was >95% with the average air quality level being 5.0 micrograms per cubic metre (µg/m

3). The recorded 24 hour average range was between 0 and 60.4 µg/m

3.

Monthly averages for PM10 emissions are detailed in Table 12. Daily average PM10 results are presented in Appendix 2.4. Figure 5 and Figure 6 show 2011 PM10 24 hour average data and the historical data since the TEOM’s commissioning in 2009.

3.1.2.4 Interpretation and Review of Results Dust monitoring and assessment continued throughout 2011 as in previous years. Dust fallout, suspended dust and real time dust were all measured in accordance with the requirements of the OEH, Development Consent conditions and the appropriate Australian Standards.

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. Figure 2 illustrates the dust gauge locations. Levels within the Antiene area have remained close to long term averages. Additionally suspended dust levels were below the NSW OEH goals.

All gauges within the Antiene area (and in close proximity to all near neighbours) displayed acceptable levels throughout the year with average insoluble levels being 2.40 g/m² for 2011 compared to 2.28g/m² recorded in 2010.

Table 10 shows average and long-term average levels for each Antiene gauge for 2011. Long-term averages are similar to those reported in previous years.

2011 long-term averages for each site showed comparable results with 2010 with an average difference of 0.02 g/m².month. Sites 2157 and 2247 showed no long-term average difference between 2011 and 2010; and site 2208 was the only site to show a decrease in the long-term averages over this period.

Background levels in the Antiene area, to the north of the mine and in the direction of Drayton’s near neighbours generally remain below the OEH licence requirements of 4g/m².month. In addition, the OEH amenity based criteria of a maximum increase in deposited dust levels of 2g/m².month in the Antiene area was not exceeded during 2011. Due to the nature of Dust Deposition Gauges, contamination of samples is very common.

Gravimetric sampling also continued throughout 2011, with average annual geometric means for total suspended particulates (TSP) for the Antiene station well below the 90µg/m³ limit as well as being slightly down for long-term average compared to 2010. Annual TEOM monitoring of PM10 indicated levels well below 30µg/m³ although monthly averages were slightly higher than in 2010 with an average difference of1.9µg/m³.

Total Suspended Particulate (TSP) monitoring was undertaken in two locations, at the north of the mining operation; one east of the CHP (Met) and the other, Lot 22, is located within the Antiene rural sub division, close to residential premises. Drayton’s sampling program following the OEH guidelines of a six-day rotational cycle. Average TSP levels at Lot 22 were well within the 90µg/m

3 annual criteria. Technical

difficulties resulted in some sampling dates not being recorded on the sampling date although these were immediately rectified with make-up runs. These technical issues have been reduced since December 2011 due to replacement of TSP monitors at both locations.

During the reporting period OEH continued to run the Upper Hunter Air Quality Monitoring Network. The nearest real time PM10 monitor to the Drayton operation is located in Muswellbrook township with results used for comparison. There is a close correlation between the results of the Drayton TEOM and the PM10 monitor in Muswellbrook indicating that particulate matter levels are representative across the region.

Real time dust monitoring in the Antiene area for PM10 continued throughout 2011. Results indicate that levels were typically in compliance with statutory limits for PM10 levels. The 24 hour average PM10 results were above the OEH limit of 50µg/m

3 twice during the year at the monitoring location. This occurred in

January and October.

On the 27th January the 24hour average was 60.3µg/m

3 at the TEOM. This was a day of high winds and high

temperatures. The Muswellbrook OEH data also indicates that max PM10 levels were very high with a maximum level of 115.73µg/m

3 during this day. Winds on the day were predominantly from the South East

with the result not reflecting particulate matter sourced from the Drayton operation.

On the 22nd

of October the 24hour average was 51.3µg/m3 at the TEOM. In assessing the 1 hour averages

for this day, very high levels of PM10 were recorded in the early hours of the morning which correlated to a strong northerly wind. 1 hour averages lowered as the wind speed reduced and turned from the west throughout the rest of the day. On this day of high particulate matter, the TEOM was located upwind of the mining operation, hence the results would not have been influence by the mine.

Three enquiries were received during 2011 regarding dust emissions. These occurred in January, February and March. Enquiries were related to perceived dust on two of the enquirer’s properties and one regarding dust visible from Thomas Mitchell Dr. These complaints were discussed with complainants with information conveyed as to Drayton’s dust mitigation measures. These enquiries did not correlate with elevated levels at the TEOM


34 of 171

Drayton offers near neighbours additional potable water supplies through filling water tanks should their tank water levels fall unacceptably low. Several neighbours have taken up the offer during the drier periods of 2011. During the reporting period Drayton engaged a contractor to clean the insides of rainwater tanks at nearby residences to assist in mitigating dust impacts on the surrounding community.

3.2 Erosion and Sediment

All water movements around the mining operation occur in either enclosed pipelines or open drains adjacent to mine haul roads. Major pumping is undertaken through large enclosed pipes leading directly from pumps to the destination dam. Excess water from in pit water tanker fill locations flows via open drains back to site water storage dams. These drains are located adjacent to mine haul roads and are constantly changing as roads alter.

With regard to rehabilitation areas, contour banks are constructed on all sloping areas of rehabilitation with average grades of drains being between 0.5 to 1%. This ensures that erosion is minimised during rainfall events by sustaining a low intensity flow within contour drains.

3.3 Surface Water

There are two main drainage basins that leave the Drayton site. These catchments are Bayswater Creek (flowing to the south east) and Ramrod Creek (to the northwest and to the north east).

Surface water monitoring is undertaken on the dams on the creeks, or directly from the creeks whenever there is sufficient water in the creeks available for sampling purposes. Figure 8 illustrates the locations of the sampling sites.

The following standard water testing is carried out on all samples:

3.3.1 Bayswater Creek (1895)

Bayswater Creek flows south eastward from the Drayton boundary. It is monitored on a monthly basis from dam 1895 located at the Far East Tip. This dam has a total storage capacity of 130 ML and collects runoff water from non mining related areas. The results of water quality sampling from Dam 1895 are provided in Table 13 below.

It should also be noted that this dam is not impacted on by any mining activity.

3.3.2 Ramrod Creek

The Access Road Dam (2081) is located on a tributary of Ramrod Creek, leading off the site to the northeast. It has a storage volume of 750 ML and is used to supply water to the Coal Handling Plant (CHP) for coal processing and dust suppression on stockpiles. Water from this dam is also transferred back to the workshop area for washdown and industrial usage. The results of water quality sampling from Dam 2081 are provided in Table 14.

Dam 2081 is a prescribed dam regulated by the Dams Safety Committee (DSC) and undergoes periodic inspections as required by the DSC.

In addition to the surface monitoring of the main drainage basins that leave the Drayton site, 6 other dams are also monitored on a monthly basis. The locations of these dams are illustrated in Figure 8. Most dams are mine water dams with the exceptions being dams 2090 and 2221. A summary of the results of the water quality sampling is presented in Table 15. The complete data is provided in Appendix 2.1.

3.3.3 Interpretation and Review of Results

During 2011, Drayton received the highest annual rainfall recorded since the installation of the onsite meteorological station in 1981. Water levels in main dams were stable throughout the year and the site increased in storage capacity via the introduction of the completed ES pit as a site water storage structure.

During 2011, water quality monitoring continued as in previous years. Salinity levels remained stable in most dams throughout the year. Those dams within the mining operation which are utilised for surface water storage showed little variation in water quality during the year.

Dam 1895 is located at the base of the Far East Tip, to the east of the mine. This dam collects runoff from the Far East Tip, an area rehabilitated in the early 1990’s and is unaffected by current mining operations. This dam has a total holding capacity of 130ML.

Ongoing monitoring has revealed that the water quality in this dam has stabilised reflecting alkaline conditions for pH and higher than traditional background salinity levels. This reflects natural saline conditions typical of upper hunter catchments.

Dam 2081, located on the Drayton entrance road is designed to store up to 750ML of mine water for use in industrial processes. This dam has a high turnover of water which is pumped from the Industrial Dam (1969). Water quality has remained constant thought the year due to the nature of the incoming water.

Dam 2114, located within the Drayton rail loop, collects surface runoff from the Coal Handling Plant (CHP) and returns water to the Drayton internal water management system. Water quality remained generally stable in this dam throughout 2011. Electrical conductivity and salinity dropped slightly across the year due to influx of rainwater and de-siltation work. Please refer to section 2.8.1 Water Management for discussion on a water discharge from this Dam on 15

th June 2011.

Dam 2221 is located off site in the Antiene rural sub division area. This dam has no connection to mining activity and is monitored for background purposes only. Dam 2221 was traditionally a small farm dam, however stock no longer have access to the dam and its sole purpose is to supply water to native animals. This dam exhibits similar, slightly alkaline conditions as most of the onsite mine water dams. Water quality in the dam has remained stable throughout 2011.

Dams and voids are monitored on a monthly basis for storage volumes. Meter readings are also performed on a monthly basis to record details of pumping volumes. The site water balance is recalculated each month using this information and rainfall volumes recorded by the onsite meteorological station. This information is provided to site managers at the monthly Environmental Management Committee (EMC) meetings to enable effective surface water management through regular assessment of the current storage capacity and monthly water usage requirements.

3.4 Groundwater

Piezometers were initially established during the exploration-drilling program and subsequently throughout the mining process as further exploration drilling was carried out. Some piezometers have been destroyed as the mining has progressed.

At the end of 2011, 12 piezometers were being monitored on a monthly basis. Some piezometers could not be sampled on each monitoring occasion due to insufficient water or obstructions. Piezometers R4171A and R4171B were destroyed by mining during 2011.

The locations of the piezometers monitored are illustrated in Figure 9. A water level indicating instrument was used to determine the standing water level in the piezometers. A summary of the groundwater levels is presented in Table 16. The complete results from the 2011 groundwater monitoring program are shown in Appendix 2.2.

Drayton does not extract groundwater from established bores. Groundwater is extracted only through infiltration to mine voids.

3.4.1 Interpretation and Review

Piezometer levels from monitoring locations to the south of the mine are generally steady with the exception of piezometer R4220 which continued a steadily dropping trend over the past 3 years since 2009. This piezometer exhibited a sharp drop in level between monitoring in October and November 2011. Mining disturbance has encroached slowly towards the monitoring location and is now in close proximity the piezometer location. The groundwater level has been steady since November 2011 at the R4220 piezometer. All other piezometers to the south of the mining area have remained steady throughout 2011.

Piezometers located in the northern areas of the mining lease continue to have displayed a gradual decline in 2011. This gradual decline in groundwater levels to the north of the mining area has been a continuing trend over several years with the exception of 2007, during which an extreme high rainfall event occurred.

One piezometer to the north of the mine did not follow the general declining trend. Piezometer F1167, located in the Antiene area, followed a generally increasing trend throughout 2011 resulting in a recovery to pre 2005 groundwater levels. This trend began in mid 2010, following several years of slight decline to steady trends likely to be the result of low rainfall. This piezometer, located in the Antiene area, illustrates the complexity and resilience of groundwater conditions in the general vicinity of the mine. Strong rainfall throughout the year has lead to the recharging of groundwater levels in the Antiene area which are not considered to be significantly affected by mining activity.

3.5 Contaminated Land

During 2011 there was no remediation works required to contaminated land.

3.6 Threatened Flora

Three natural woodland communities and five rehabilitation and grassland communities have been identified at Drayton. Of these, the Forest Red Gum Open Forest and Woodland (consisting of regrowth woodlands totalling 8 hectares) contains a species composition consistent with the definition of Hunter Lowland Red Gum Forest. This form of forest has been declared under the Threatened Species Conservation Act 1995 as an Endangered Ecological Community.

An assessment of significance was conducted for the Forest Red Gum Open Forest and Woodland which determined that the project is not expected to have a significant impact on this community. No other threatened vegetation communities were identified.

An area also exists to the north of the mining leases of Drayton which was proclaimed and gazetted in 1987 as a Wildlife Refuge. It allowed planned land use of all areas of the Drayton land holding, whilst still respecting wildlife values. Ultimately this means that mining and grazing could coexist and continue in the mining lease area, whilst the Antiene area would be retained as a passive wildlife area. Besides providing a buffer zone between residents and the mine, the Antiene area provides remnant woodland for the continuing existence of natural ecosystems.

3.7 Threatened Fauna

A total of 96 fauna species have been detected including 67 bird species, 27 mammal and two reptile species. Of these, ten were identified as threatened species listed under the Threatened Species Conservation Act 1995 and the Environmental Protection and Biodiversity Conservation Act 1999. An assessment of significance for each of these species indicated that the operation would not have a significant impact on any of these species.

During 2011, logs were brought into the southern offset area to provide habitat augmentation for wildlife. These habitat logs have been placed to provide habitat for ground dwelling mammals and reptiles in the southern offset area.

3.7.1 Feral Animal Control

A baiting program was planned to occur in 2011 in conjunction with the local regulatory authorities however this was hampered by continued wet weather. It is envisaged that a program will be implemented in 2012. Where possible, Drayton implements a coordinated feral animal control program with neighbouring property holders. This integrated approach is designed to maximise effectiveness of control for target species across a broad area.

3.8 Weeds

An ongoing weed management program continued throughout 2011. Weeds including St John’s Wort and Prickly Pear were targeted. Results of the weed management program are very encouraging with most target weed species occurring only in small isolated patches on Drayton owned land. This program will continue for 2012 and beyond.

Weed infestations targeted during 2011 are shown in Figure 10.

3.9 Blasting

Both mining lease conditions and noise approval conditions include requirements for the monitoring and control of blasting impacts. The Office of Environment and Heritage (OEH) and the Department of Planning and Infrastructure (DoPI) have established limits for blasting activities at Drayton. Applicable limits include ground vibration to be less than 10 millimetres per second (mm/sec) and air blast to be less than 120 decibels (dB) at any residence on privately owned land for all blasts, with five percent of blasts allowed to exceed 115 dB and 5 mm/sec.

Blasting is permitted under Drayton’s Project Approval between the hours of 0900 and 1700 Monday to Saturday (EST) and 0900 – 1800 Monday to Saturday (DST).

Drayton utilise an internet based blast monitoring system which gives access to immediate blasting information for all blasts. The locations of the Drayton blast monitoring units are shown in Figure 11.

In addition, Instantel Portable blast monitoring units are also utilised to enable additional monitoring to be undertaken in specific locations as required. These units are manually monitored and downloaded upon return to base. Calibration and maintenance of the units occurred in December 2011.

Procedures have been implemented to ensure Drayton minimises impact of blasting on near neighbours and operates within licence and project approval conditions. They include the following:

Loading blasts according to Drill and Blast Engineer’s design with attention given to factors such as:

o charge weight per delay;

o loading pattern of holes;

o stemming used;

o firing sequence and direction;

o maximum instantaneous charge; and

o type of blast.

Accountability for compliance lies primarily with the Mining Operations Department regarding blasting;

Meteorological conditions are considered when firing shots. In particular cloud cover and the possible presence of temperature inversions are taken into account. Blasting is generally conducted close to midday or early afternoon, when temperature inversions are least likely to occur, especially during the winter months. Drayton also utilities the ACARP MM5 sodar device for predictive impacts of blasting;

Waveforms of both air blast and vibration are available for all blasts;

Implementing an NN Strategy for blasting in the north pit;

Implementing a road closure process for closing Thomas Mitchell Drive during blasting in the north pit within 500m of the road;

Implementing electronic detonation on some blasts in the NN area; and

Designing blasts to remain below internal limits well below regulatory limits.

Drayton is also involved in a continuing research project, funded by ACARP in regard to the identification of specific weather conditions relating to blasting activity. This is a joint research project involving a number of Upper Hunter mining companies. This project is referred to as the SODAR project.

Table 17 gives a summary of all blasting activity at Drayton during 2011. A total of 178 blasts occurred during 2011. All blasting data can be found in Appendix 2.8.

During 2011 a total of 178 blasts occurred, with one reportable exceedance of air blast criteria. The exceedance occurred at 3:59pm on 6

th May 2011 during blasting in East Pit. The incident resulted in an air

blast level of 122.4 dB(L) at the de Boer monitor.


47 of 171

Investigation revealed that a combination of waveform reinforcement, stemming ejection caused by undetected bridging between holes and calm weather conditions at the time of the blast lead to the exceedance occurring. The incident was reported and an incident report sent to the Office of Environment and Heritage (OEH) in accordance with requirements and to the Department of Planning and Infrastructure (DoPI). No complaints were received as a result of the blast.

On the 12th February and the 18

th of July 2011, 3 separate shots were fired within the day. This occurred to

reduce the risk of unplanned discharges due to reactive ground found at Drayton. No complaints were received on these days.

Two separate blast monitor faults resulted in loss of data during 2011. In late April 2011, the Sharman monitor failed resulting in the loss of data for four blasts at that location. In June 2011, a fault with the de Boer monitor required a complete replacement of the unit. The results from seven blasts were lost for the de Boer location. On all occasions the data available from the other monitors in the area indicated that the blasts were within limits.

A total of 18 enquiries were received during 2011 related to blasting activities of which 14 were considered complaints, four did not relate to Drayton activity. Of these 12 related to vibration, ten to noise and two were received via regulators.

All enquiries were investigated and appropriate responses made. The enquirers were given details of monitoring data recorded for the blast under enquiry where applicable. Details of all enquiries received during 2011 are contained in Section 4.1 of this report.

3.10 Operational Noise

3.10.1 Noise Criteria and Control Procedures

Drayton undertakes attended and real time noise monitoring to assess noise levels against relevant licence and approval conditions. An independent contractor is engaged to conduct quarterly attended noise monitoring to assess compliance.

3.10.2 Real Time Noise Monitoring

Drayton conducts real-time noise monitoring using a BarnOwl® noise monitoring system which operates continuously 24 hours per day. This system facilitates production of graphical and numerical data as well as recording and maintaining noise emission files on a five minute basis. Monthly average noise levels for the day, evening and night periods during 2011 are provided in Table 18.

These levels have been recorded by the BarnOwl® located approximately 150m from the Drayton rail spur in the direction of the nearest residence (Figure 14).

Figure 12 illustrates typical daily noise levels recorded by the system. The red lines indicate mine related noise including train noise from both Drayton and Mt Arthur Coal operations. The two operations co-use the Drayton rail spur to transport coal to the Newcastle port via the main Northern rail line. The blue line represents all other noise sources such as highway traffic, birds, dogs, wind, rain, insects and other domestic noises.

Attended background noise levels were measured at six locations during 2011. The locations of all noise monitoring stations are shown in Figure 15. The locations are focussed on the local community and near neighbours. These include the De Boer residence, Doherty residence, Halloran residence, Horder residence, Collins residence and Robertson residence.

The complete results for noise monitoring are in Appendix 2.6. A summary of the background noise measurements is provided in Table 19 and Table 20.

Attended monitoring results include all noises being recorded during a 15-minute period. These regularly include highway traffic, birds, insects, dogs, wind, rain and domestic noise. Mining contributions are included, but are not the sole source of noise results indicated in Table 19 and Table 20. Results from 2011 attended noise monitoring in the Antiene area generally indicated that noise levels are consistent with long term averages.

The de Boer residence is located north east of the mine and approximately 500m from the New England Highway. Major noise influences at this location consist of highway traffic, insects and birds. The noise monitoring station located near this residence and results of attended noise monitoring indicate that noise from rail movements may impact this residence. Levels remain generally within regulatory limits.

The Doherty residence is located on Balmoral Road. Attended noise monitoring at this residence indicate that the major influences on noise levels are insects, birds and traffic on New England Highway and Thomas Mitchell Drive. On occasions Drayton and other mining operations are audible from this residence.


51 of 171

The Halloran residence is also located on Pamger Drive. In relation to this monitoring station several large native trees surround this site which are frequented by a variety of native birds such as cockatoos, king parrots, galahs and rosellas. This influences ambient background noise levels significantly. Other influences include traffic from the New England Highway, wind and traffic on Pamger Drive.

The Robertson residence is the closest residence to the mining operation. This location is influenced predominantly by traffic on Thomas Mitchell Drive with mining related noise also audible during attended noise monitoring. This residence is within an acquisition zone and has made no complaints regarding noise from Drayton.

The Collins residence was monitored during 2010 and 2011. This location is approximately five kilometres from the Drayton mine. Noise emissions detected at this location are comprised almost solely of highway noise. Monitoring at this location ceased in late 2011 due to lack of audible mine noise.

The Horder residence, is located east of the mine and west of the New England Highway. Noise emissions at this location commonly detect traffic, birds and wind through the trees. Mine related noise is occasionally audible at this location however the residents have indicated that noise is generally not intrusive. This residence also falls into an acquisition zone.

During 2011, 14 complaints were received in relation to noise, 10 of which related specifically to noise from trains and railing activities. Four further train noise enquiries were received which did not relate to Drayton train activity as Drayton did not have any trains on the rail spur on the dates and times subject to enquiry. As the rail infrastructure is shared with Mt Arthur Coal, all complaints and enquiries received relating to train noise were communicated to Mt Arthur Coal staff. Rail related complaints were also referred to Drayton’s rail carrier for further investigation.

Six noise complaints and enquires were received via the DoPI during 2011. In response to complaints received, an independent assessment was requested by the DoPI during 2011 on the de Boer residence. The results showed general compliance with the noise criteria. Subsequent correspondence from the DoPI indicated that rail noise remains an issue despite compliance with relevant criteria. The DoPI require that the rail spur be accessed only by locomotives approved to operate on the NSW rail network in accordance with noise limits published in RailCorp’s Environmental Protection Licence (EPL 12208). This requirement has been communicated to Drayton’s rail carrier. Drayton’s carrier has confirmed that all locomotives operating on the rail spur have been certified compliant with the appropriate noise criteria. Regular inspections and maintenance are performed on both locomotives and wagons by the rail carrier. Table 21 below, details noise mitigation measures outlined in Drayton’s environmental assessment and approval.

7 A 4m berm and/or wall would be constructed along the eastern side of the coal haul road from ROM stockpile to meet the existing ROM hopper wall

New ROM stockpile not constructed as yet.

8 A sound power level limit of 103 dB(A) each for three new reclaimers and one ROM coal stacker

No new reclaimers or stackers have been commissioned as yet.

9 Steel sheeting would be installed on the northern face of the secondary crusher building after the removal of the rotary breaker and installation of the new screen and crusher

Not completed as yet, however noise monitoring has not reflected any increase in noise emissions even without sheeting.

10 Upgraded exhaust mufflers on some trucks with the exception of the South Pit overburden fleet

Mufflers altered on trucks within fleet.

3.11 Visual - Lighting

Drayton has achieved low visual impact for its operation by judicious clearing during initial construction. Remnants of the initial woodland have been retained around and throughout the site by careful layout of infrastructure and clearing of the minimum area required. Mature trees provide effective screening of areas such as the Coal Handling Plant (CHP), Rail Loadout facilities and general administration area.

Tree planting continues to be a component of rehabilitation programmes. In the future these plantings will provide additional screening of mining activities as well as a corridor for wildlife movement between refuge and offset areas.

The Antiene Wildlife refuge is passively managed with general exclusion of stock. This has resulted in extensive regeneration of native vegetation including Ironbark, Grey Box, Red Gum and Spotted Gum.

During 2007, some 2060 native tree seedlings were planted along Thomas Mitchell Drive to act as future visual barrier for future mining developments. These successfully established and continue provide a screened barrier for travellers along Thomas Mitchell Drive.

Mobile lighting is actively managed to prevent impact on both Thomas Mitchell Drive and the New England Highway. Potential impacts from lighting plants located on high dumps are an issue discussed by managers at monthly Environmental Management Committee (EMC) meetings. These lights, essential for night-time operations, are carefully positioned to prevent glare from impacting drivers.

3.12 Aboriginal Heritage

Archaeological surveys conducted for Drayton’s project approval granted in 2008, discovered a total of 39 Aboriginal sites. Of these a total of 26 were salvaged in 2009, subsequent to the DoPI Approval of the Aboriginal Cultural Heritage Management Plan.

In addition to these, five European sites were identified. Most will not be impacted as a result of mining operations.

No salvage work was undertaken and no Aboriginal Heritage issues arose during 2011. .

3.13 Natural Heritage

Drayton has no identified natural heritage sites on the Drayton mine site, nor do any lands under the control of Drayton.

3.14 Spontaneous Combustion

Spontaneous combustion remains an important environmental issue as it creates heat, fumes, dust and the potential for offsite odours. It is continually addressed and efforts are continuously placed on the prevention and control of fresh outbreaks, as well as continuing to rectify problems that occur in established overburden dumps and mining areas.

All overburden tips, both in pit and out of pit continue to be monitored for outbreaks of spontaneous combustion. The Far East Tip, which contains 24 Mbcm of overburden, remains free of spontaneous combustion. The East Tip, containing 14 Mbcm of overburden, also remains free of spontaneous combustion. The South Tip, which contains 38 Mbcm of overburden, shows no sign of spontaneous combustion.

The Great North Tip does not exhibit any sign of spontaneous combustion in areas of rehabilitation; although open faces on the most eastern, southern and northern extremity, exhibit isolated outbreaks of spontaneous combustion. The western face of the great north tip lies within the Bayswater (No 2) void area.


55 of 171

Active mining is continuing in the northern end of the East Pit with small outbreaks of spontaneous combustion occasionally evident in the upper northern batter primarily in dragline spoil. These areas are addressed with capping however spontaneous combustion still remains and will require ongoing surveillance and further capping as mining continues.

During 2011, infilling of the west pit area continued. Spontaneous combustion outbreaks during the reporting period were primarily concentrated in the South and East Pits in unshaped and inaccessible dragline spoils. These areas are regularly monitored with mine planning focusing on managing existing and preventing new occurrences.

Drayton completes six monthly reports to the OEH regarding spontaneous combustion management.

Drayton has implemented a Spontaneous Combustion Management Plan to meet both statutory and company requirements. This plan indicates the causes of spontaneous combustion, determines accountabilities for its management, lists remediation work to prevent recurrences, and specifies monitoring and reporting requirements.

3.15 Bushfire

Drayton has reduced the possibility of an outbreak of fire on site through a system of peripheral roads that act as firebreaks. Access to water tankers is available if outbreaks should occur on site.

All electrical substations are also kept weed and grass free to ensure the risk of fire is minimised at all times. Similarly, the growth of grass and weed around fuel storage areas is also kept under control.

Annual inspections are carried out to assess the status of the Drayton property boundary and neighbouring properties regarding the potential for bushfires. Plans are then made to address any areas of significant risk.

Drayton also has a Bushfire Management Plan that will be reviewed in 2012.

3.16 Mine Subsidence

Drayton is an open cut coal mine with no underground workings. Therefore mine subsidence is not an issue for Drayton.

3.17 Hydrocarbon Contamination

Drayton has various hydrocarbon (diesel, oils, etc.) storages. The primary diesel tank, with a capacity of 860,000 litres, is located within a fully bunded area near the workshop. Additionally, there is an in pit fuel facility, with above ground diesel storage tanks of 247,000 litre capacity. These are also located within bunded areas. All bulk storage tanks and containers of hydrocarbons are stored within appropriate bunding and kept in neat and tidy condition. Contamination is kept at a minimum, with any large spillages being reported internally through Drayton’s incident reporting system. Tanks and storage areas are located such that any incidents will not lead to offsite discharge and impacts.

Drayton also has an oil pollution control dam, located below the main workshop and lube facilities. Any runoff from the industrial area, reports to this dam, where a filtration system separates contaminants from water. Water is then allowed to pass through to a major storage dam for reuse on site. Oils, grease and other contaminants are collected in storage tanks, which are serviced by a waste contractor on a regular basis.

3.18 Methane Drainage / Ventilation

Drayton is an open cut coal mine with no underground workings. Therefore methane drainage and ventilation issues are not relevant to Drayton.


56 of 171

3.19 Public Safety

Drayton offers no access to the public of any mine working areas. Drayton operates 24 hours a day, 7 days per week. During weekends, maintenance and some additional overtime crews operate. Contract security is in place during higher risk periods on weekends and public holidays.

A boom gate system operates on key access routes which restrict access to employees and inducted contractors. Signage around the mining lease boundary fences has been erected notifying the public not to enter the mining areas.

3.20 Other Issues and Risks

3.21 Meteorological Monitoring

During 2011, weather conditions were monitored onsite using an online automatic weather station. Measurements are logged every five minutes with data being immediately transferred into a log file located on Drayton’s electronic database.

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.


63 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.

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

st 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.

Table 28: Rail Enquiries Date Resident Issue Outcome

9/01/2011 Lot 22 Train Noise RH called to complain about train noise on the preceding two nights. Sound level investigation conducted. Discussed with RH.

27/05/2011 Lot 22 Train Noise Train noise from last few hours. Drayton had only one train and it arrived 20 minutes prior to call. Do not believe it was a Drayton train

17/10/2011 Lot 27 Train Noise Communication via DoP regarding train noise at lunchtime and 4:30pm. Advised DoP that one train noise was at the time indicated but within limits and there were no Drayton trains at the other times stated

19/10/2011 Lot 27 Train Noise Communication via DoP regarding unbearable train noise at from 10:15pm onwards the night before and at4:41am, they advised that the continual humming of the trains loading awakened them and disturbed their sleep. Advised DoP that there were no Drayton trains on the night of the 18.10.11 or at all on the 19.10.11

20/10/2011 Lot 27 Train Noise Communication via DoP regarding train noise on the 19.10.11 from 10:30pm onwards concerning disturbing continual humming train noise. Advised DoP that there were no Drayton trains on the 19.10.11


73 of 171

7/12/2011 Lot 27 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.
