Coal Services/Lamberts Gully 2013 AEMR Page 1

1 INTRODUCTION

Springvale Pty Ltd (Springvale Coal), a subsidiary of Centennial Coal Limited, owns and operates the Springvale Colliery, Springvale Coal Services Washery (Coal Services) and the previously operating Lamberts Gully Open Cut Mine (Lamberts Gully).

For the 2013 Annual Environmental Management Report (AEMR), Coal Services has been included for the third time with Lamberts Gully as previously it was covered by the Springvale Colliery AEMR. The AEMR includes both Coal Services and Lamberts Gully (Coal Services/Lamberts Gully) to reduce the confusion generated by the common Environment Protection Licence (EPL 3607), leases and overlapping consents covering essentially the same land area.

This AEMR relates solely to the reporting period 1 January 2013 to 31 December 2013.

The Reject Emplacement Area (REA), the co-disposal area, Energy Australia’s (prior to September 2013 owned by Delta Electricity) ash emplacement, and Council’s waste disposal activities will extend well beyond the life of the Lamberts Gully open cut. Access to the REA will remain open for the remaining life of the Washery and/or the Springvale Colliery. The REA will remain the responsibility of Coal Services for both management and rehabilitation.

Coal Services/Lamberts Gully continues to consult with the Lithgow City Council (LCC) and Energy Australia regarding access to both the Council Waste Disposal Facility and Ash Emplacement Area. The LCC owned landfill area is subject to a separate development consent. The area has been partly fenced and is the responsibility of the LCC. Energy Australia commenced construction of a new ash emplacement facility in 2013, which is located on Energy Australia owned land to the east of the existing ash emplacement.

During the reporting period there was no coal produced from open cut mining at the site and there are currently no plans to recommence mining at Lamberts Gully.

1.1 Historical Mining

Coal mining began at the Lamberts Gully site in 1942 under the name Big Spur. The site was later named Western Main. Below the open cut mine is an extensive series of underground workings which were part of the old Western Main Colliery, which mined the Lithgow Seam for over fifty years from the 1940’s to 1990’s (Brown, J 1989). Open cut mining has also occurred on the site since the 1940’s as an adjunct to the underground operations.

Between 1980 and 1994 the previous owners (Clutha Coal, then BP Coal, Novacoal Australia and Cypress/Samsung Joint Coal Venture) developed the following open cuts:

Bund Cut, Road Cut and Road Cut Extension– these were developed adjacent to the Castlereagh Highway and were designed to create both a bund wall and an adjacent void to allow backfilling with ash from Mount Piper Power Station.

Western Main Open Cut Extension – this extension mined the barrier between the underground workings and the previous bund cut.

Knoll Cut – this cut extended from Mudgee Road south towards the existing Washery and removed previous coal waste disposal areas which were causing acid leachate issues.


1.2 Description of Operations

Springvale Coal purchased the Western Main Colliery site from Novacoal Australia in October 1994 and took over the assets and leases. Coal Services/Lamberts Gully was located within the Western Main Colliery area (Appendix 6 - Figure 1).

The Coal Services/Lamberts Gully site is located north of Wallerawang and Lidsdale on the Castlereagh Highway. The site is bordered by the Blackmans Flat Village to the east, Ben Bullen State Forest to the south and the Mount Piper Power Station (including its ash placement area) to the northwest (refer to Appendix 6 - Figure 1). When mining was completed in 2010, Springvale Coal was the operator of Lamberts Gully, using Big Rim as the mining contractor.

Coal Services/Lamberts Gully consists of the following:

Administration offices and workshop;

ROM stockpile;

Coal Handling Preparation Plant;

Product coal stockpile;

Sedimentation dams;

Conveyors and associated infrastructure;

Reject Emplacement Areas; and

Proposed Waste Emplacement Facility.

Coal produced from underground mining at Springvale Colliery is sized at the Screening and Crushing Plant located adjacent to the ROM stockpile at Springvale Colliery. The sized product is then delivered directly to either Wallerawang Power Station or Mt Piper Power Station or Coal Services by overland conveyor. This product is stockpiled at Coal Services for either processing in the Coal Handling Preparation Plant (CHPP) or for delivery to Mt Piper Power Station.

Coal processed at the Coal Services CHPP is delivered to Lidsdale Siding via the overland conveyor for despatch by train to both Port Kembla and Newcastle to domestic markets or export markets by ship.

Coal Services/Lamberts Gully provides employment to 22 people and can operate 24 hours per day, 7 days a week.

1.3 Submission of the Environmental Impact Statement

An Environmental Impact Statement (EIS) for the Western Coal Services Project was submitted to the Department of Planning and Infrastructure (DP&I) in July 2013 (RPS 2013). This has now been referred to as the July 2013 EIS.

Springvale Coal is seeking approval to:

Upgrade the existing facilities and infrastructure within the Coal Services site to provide a total processing capacity of up to 7 Mtpa;

Construct processing infrastructure including additional conveyors and transfer points and other coal handling requirements to cater for the upgraded Washery facility within the existing disturbance footprint of the Coal Services site;

Extend and enlarge an existing reject emplacement area on the Coal Services site to enable sufficient reject disposal capacity for a 25 year life;

Increase the utilisation of the return side of the existing Overland Conveyor system to enable up to 6.3 Mtpa of coal to be delivered to Lidsdale Siding;

Construct a private Link Haul Road between the Coal Services site and the existing private haul road from Angus Place Colliery to Mt Piper Power Station;

Improve the current water management systems on the Coal Services site by better separation of clean and dirty water streams prior to either reuse or discharge off site;

Integrate the existing approved transport and processing of coal at Springvale Coal Mine and Angus Place Colliery into the one consent;

Integrate the remaining rehabilitation, monitoring, water management and reporting requirements associated with the Lamberts Gully Open Cut Mine, which occupies the Coal Services site; and

Allow continued use of all existing approved infrastructure, facilities and activities associated with the transport and processing of coal from each mine gate and the point of delivery to the Coal Services site. This infrastructure includes the existing conveyors, private haul roads, Kerosene Vale Stockpile Area, REA, services, access roads, car parks and buildings.

1.4 Current Consents, Leases and Licences

1.4.1 Consents

A Development Application (DA) for an extension to Lamberts Gully was submitted to the then Department of Planning (DoP), now DP&I on 20 October 2005, accompanied by a Statement of Environmental Effects. The Project Approval (06-0017) was granted by the Acting Minister of Planning on 12 May 2006.

On 5 December 2007, a submission was made to the then DoP for a modification to the project approval

to allow for the removal of 100,000 tonnes of coal from the ramp area to be constructed on behalf of LCC for a future waste disposal facility. The modification was granted on the 3

September 2008 and

work has been completed on the ramp area. Refer to Table 1.1 for a summary of consents.

As outlined in Section 1.3 above, the Western Coal Services Project EIS was submitted in July 2013 and is currently awaiting determination. Table 1.1 outlines the consents for Coal Services/Lamberts Gully.

Coal Services/Lamberts Gully.

This was not undertaken in 2013. The separation of

EPL’s will be completed following the new consent

approval of the July 2013 EIS.

2.2 Exploration

No exploration was carried out at Lamberts Gully/Coal Services during the reporting period. There are no current plans for any future exploration.


2.3 Land Preparation

Land prepared for Coal Services/Lamberts Gully has been calculated as an area of approximately 80 hectares which is essentially comprised of areas involved with A Blocks, C Blocks, F Blocks, the perimeter of the REA and other miscellaneous areas.

There was no land preparation in the 2013 reporting period as mining had been completed in June 2010. Land preparation was completed by Energy Australia to construct a new ash emplacement facility with this being located in the Lamberts Gully/Coal Services consent area.

The 2010 Revised Mine Closure Plan outlines the final land use for A and B Blocks including a long term REA for Springvale. E Block is being utilised by Energy Australia for ash emplacement from their Mount Piper Power Station. The majority of areas outside A and B blocks are completely rehabilitated or in the process of rehabilitation. The Mine Closure Plan will be updated following the approval of the Western Coal Services Project which was submitted to the DP&I in July 2013.

2.4 Construction

There was no construction during the reporting period; although there were upgrades to a number of water management structures (see Section 2.9). During 2013 an extra conveyor was set up at the Coal Services CHPP site to allow ROM coal to be loaded onto the overland conveyor to Lidsdale Siding.

Other activities on site relating to coal processing included operation of plant and equipment for the stockpiling and reclaim of coal along with maintenance of stockpiling and processing plant and equipment.

A total of 357,243 t of reject material was generated from the processing of coal at Coal Services during the reporting period. There was no recorded breakdown between coarse rejects and fines, although from previous assessments, a 50% split is fairly indicative and has also been adopted for the AEMR.

Coal fine reject (tailings) produced at the CHPP, are pumped from the Washery to the A-Pit, which is the licenced reject emplacement area (REA). Coarse reject is transported via truck to the REA.

2.7 Waste Management

Waste generated on-site includes: packaging, timber, waste oil, oil filters, oily water, empty oil drums, metal, hoses, and paper. Oil drums and filters (after rinsing and crushing) are disposed of with waste metals through metal recyclers. Aluminium cans are a separate stream which is sold to metal recyclers. Waste oil (and oily water) is disposed of by licensed waste transporters and recyclers, or treatment plants. Remaining waste is removed from site by a licensed waste contractor. Table 2.5 below summarises waste disposal and recycling in 2012 compared to 2013.

Table 2.5: Waste Management Summary

Regular waste management inspections are completed by the waste contractor, JR Richards. During 2013, approximately 26% of waste was recycled from the Coal Services/Lamberts Gully operation.

2.8 ROM and Coal Stockpiles

During the reporting period stockpiling and processing activities were carried out to address production levels from the Springvale Colliery and demand from both domestic customers (Energy Australia) and export markets.

Table 2.6 outlines the stockpiled coal at the Coal Services site at the end of the AEMR reporting period.

2.9 Water Management

Water management at Coal Services/Lamberts Gully is undertaken in accordance with the Coal Services/Lamberts Gully Water Management Plan. Water used in coal processing and dust suppression is supplied from existing surface dams. Water is discharged through the Licensed Discharge Point 6 (LDP006) (see Figure 4 - Appendix 6). Regular water monitoring assesses quality of discharge under the site EPL conditions.

The water storage capacities and volumes are reported in Table 2.7. There are several silt traps and sumps on site, but these have not been included in the table as water storages.

Photo 4: The Main Sediment Pond at Coal Services

If the July 2013 EIS is approved, there will be several upgrades to the water management system at site including the addition of approximately 15ML of pollution control storage.

2.9.1 Potable Water Usage

Potable water usage is metered by LCC and reported in the Springvale AEMR. Drinking water for employees is sourced from a local commercial drinking water supplier.

2.9.2 Process Water

Water to be used for process water is pumped from Cooks Dam to the Coal Services CHPP water storage tanks via pontoon mounted and standby submersible pumps. This system is used to minimise the risk of discharging poor quality water from the Coal Services/Lamberts Gully site. A further submersible pump is set up to pump excess water make from Cooks Dam to the DML Dam for future use at the Coal Services CHPP.

2.9.3 Water Management System

Surface water management systems consist of clean and dirty water flow paths. Excess surface water is discharged through LDP006 (see Appendix 6).

Existing surface water runoff is managed through drainage channels, pipelines, pumps and a series of dams. The drainage channels follow the site contours and natural creek lines. There are a number of existing dams on site, serving a range of purposes for the site’s operations.

The main surface water actions completed in 2013 included:

Ongoing investigation into the inflows of water through overburden into the old underground workings and then into Cooks Dam (see Section 2.9.4);

Construction of clean and dirty water drains at Coal Services (see Photo 5 and 6);

Installation of additional groundwater piezometers (Photo 7); and

Erosion and sediment controls upgraded at several locations including near Sediment Dam 2.

2.9.4 Water Management Studies

Cooks Dam Investigation

A preliminary investigation report was completed by RPS Aquaterra in 2013 regarding inflows into Cooks Dam. Extra groundwater inflows result in the exceedance of pumping capacity to DML Dam, causing discharge to LDP006. Without pumping, Cooks Dam will discharge naturally. Upgrades to the site water management system will continue in 2014 in consultation with the EPA.

Several bores have been installed into the goafed mine area to enable the calculation of the volume of water that is held in storage. Close monitoring of the water level response to any rainfall events will enable the determination of the amount of infiltration/recharge that the underground workings are receiving. Potential water level decline within the underground in response to the ongoing discharge to Cooks Dam will also be able to be assessed.

In 2014 the following will be undertaken:

RPS Aquaterra to continue the study into the source and magnitude of inflows;

Consultation with the NSW Office of Water (NOW) and the EPA as required;

Quantification on the amount of water stored within the workings and the rate of recharge/infiltration to the workings;

Continued water testing;

Identify the possibility of offsite influences, notably the Mt Piper ash emplacement and drainage works;

Consider options for remediation measures to reduce the risk of continued seepage into Cooks Dam; and

Hydrodynamic Assessment and Reporting.

Pollution Studies and Reduction Programs

The following pollution studies and reduction programs are required by the EPL 3607.

U1 Sediment dam storage capacities

U1.1 The licensee must undertake works at the Centennial Coal Services site to ensure that the Main Sediment Dam, the Stockpile Sediment Pond and the Washery Sediment Dam have the capacity to store a 95th percentile (56mm) 5 day rainfall event.

These works must be completed by 9 May 2014.

The Stockpile Sediment Pond was desilted during 2013 to create additional storage capacity. All three dams were surveyed for storage capacity in January 2014.

U2 Groundwater seepage interception system

U2.1 The licensee must design and implement a groundwater seepage recovery system at the Coal Services portion of the premises such that all major or significant groundwater seepages that would otherwise flow in to the site's dirty water system and discharge through LD6 are captured and recycled within the closed system of the coal washery's water supply.

The licensee must design and implement the groundwater seepage interception system by 31 July 2013.

A sump and low flow pump have been installed below Cooks Dam adjacent to the spillway to mitigate the issue of groundwater seepage. An additional sump and low flow pump have been installed immediately upstream of LDP006 to minimise low flow poor water quality to discharge through LDP006.


U3 Assessment of potential impacts of pollutants at LDP6

U3.1 At Point 6 (LDP6) the licensee must monitor (by sampling and obtaining results by laboratory analysis) the concentration of each pollutant specified in Column 1 in the table below. The licensee must use the sampling method, units of measure and sample at the frequency as specified in the columns opposite each pollutant. The licensee shall continue to monitor for these pollutants at the upstream and downstream locations within Wangcol Creek as previously nominated.

Following the collection of additional monitoring results up until 31 December 2013, the licensee must undertake an assessment of the pollutants detected in water discharged from the site via LDP6 in accordance with ANZECC water quality guidelines and provide this assessment to the Bathurst Regional Office of the EPA by 28 February 2014.

A report has been completed and will be sent to the EPA by 28 February 2014.

2.9.5 Sewage Treatment Systems

The site sewage management system consists of two Biocycle units. Sewage from the demountable buildings is connected to these systems and treated effluent is sprayed on surrounding land. Maintenance of the Bio-cycle unit is contracted to a local plumbing service provider.

2.10 Hazardous Materials Management

A Safety Data Sheet (SDS) register is maintained at Coal Services/Lamberts Gully. The main potentially hazardous materials at site are flocculent and oil and grease.

Mining ceased during 2010 so there is no requirement for blasting. With the completion of open cut mining, the diesel and waste oil tanks associated with this process have been removed from site. Big Rim coal stockpile equipment (front-end loader, dozer etc.) used on the site is refuelled by mobile tanker.

Environmental Spill Kits are located around Coal Services/Lamberts Gully. These are replenished as required.

2.11 Other Infrastructure Management

There are no other identified major infrastructure management issues apart from those mentioned in this document.


3 ENVIRONMENTAL MANAGEMENT AND PERFORMANCE

3.1 Risk Management

Environmental Management at Coal Services/Lamberts Gully is undertaken via a risk-based approach. Assessing risk against pre-determined consequence and probability criteria allows for site resources to be efficiently involved in high risk or high consequence issues.

In February 2013, a Broad Brush Risk Assessment (BBRA) was completed for Coal Services/Lamberts Gully. Table 3.1 has been updated based on this risk assessment.

The identification and assessment of environmental risks at the site has allowed management plans and procedures to be developed to minimise the potential risk on the environment and community. Management controls are required for all items which have been assessed as either high or medium risk. The site BBRA for Coal Services/Lamberts Gully is updated and reviewed annually.

3.2 Meteorological Monitoring

Meteorological data is sourced from a weather station located at the Pinedale Mine, located across the Castlereagh Highway opposite Coal Services/Lamberts Gully. An additional rainfall gauge is installed at LDP006, with data obtained via the internet.

3.2.1 Rainfall

Total annual rainfall for the reporting period is reported in Table 3.2. This shows that 2013 was a drier year (586 mm) than the long term Lithgow average (859mm).

There was a reduction in the total rainfall and number of wet days than the previous year for the Pinedale Weather Station, with 58 wet days recorded in 2013 compared to 76 in 2012. February 2013 had the highest monthly rainfall with 131.2 mm recorded.

Appendix 3 details the meteorological data from Pinedale.

Wind Speed and Direction

Wind direction and wind speed data is sourced from the weather station located at the Pinedale Mine. A summary of wind data is included in Table 3.3. A summary of wind data is included in Table 3.3 and wind roses from RCA meteorological monitoring are included in Appendix 3.

Table 3.3: 2013 Wind Data Summary

The dominant wind direction during the reporting period was from a West-North-West direction. In comparison to 2012, the most dominant wind was South-Southwest.

3.2.2 Temperature Summary

The air temperature data during 2013 is summarised in Table 3.4 below.

Table 3.4: 2013 Temperature Summary at 10m

The lowest temperature during 2013 occurred on 27 July, with a temperature of -5.4 degrees Celsius (°C) recorded. The maximum temperature recorded in 2013 was 36.9 °C which was recorded on two occasions (12 January and 18 January 2013). In comparison to 2012, the lowest temperature was -5.9 °C and the highest temperature was 32.9 °C.

3.3 Air Quality

Potential dust sources from Coal Services/Lamberts Gully include unsealed traffic areas and coal stockpiles. Dust is controlled on unsealed traffic areas by the use of water carts.

3.3.1 Air Quality Monitoring Program

In accordance with Schedule 3 Condition 17 of the Project Approval No 06-0017, an Air Quality Monitoring Program was submitted and was approved by the Director General on 13 December 2006.

Because of the close proximity of the operations, Coal Services/Lamberts Gully entered into an arrangement with Pinedale Mine to share air quality data and meteorological data.

The Air Quality Monitoring Program stipulates that dust emissions generated by the project must not cause additional exceedances of the long term impact assessment criteria listed in Table 3.5, 3.6 and 3.7.

Table 3.6: High Volume Air Sampler (HVAS) Particulate Matter: Long Term Impact Assessment Criteria

Table 3.7: HVAS Particulate Matter: Short Term Impact Assessment Criteria

Detailed air quality data is available for the twelve month reporting period and is presented in Appendix 3.

3.3.2 Air Quality Monitoring Program – Dust Results

A detailed analysis of the dust monitoring results is presented in Appendix 3. The locations of the dust monitoring stations are shown in Appendix 6 – Figure 2.

Coal Services/Lamberts Gully currently has 3 depositional dust gauges. Two of these gauges are located within the township of Blackmans Flat, whilst the third gauge is located to the south of Blackmans Flat. Data from Gauge D1 & D2 is shared by Pinedale Mine and Coal Services/Lamberts Gully. Dust Gauge D3 is owned solely by Coal Services.

Depositional dust results for 2013 show an annual average insoluble solids result of 1.6 g/m2/month for

dust gauge D1; 0.7 g/m2/month for dust gauge D2; and 1.1 g/m

2/month for dust gauge D3. These

results fall well below the guideline of 4.0 g/m2/month, as stipulated in the Air Quality Monitoring

Program. These depositional dust results were similar to the previous reporting period (0.9 g/m2/month

for D1, 0.6 g/m2/month for D2 and 0.6 g/m

2/month for D3).

Coal Services/Lamberts Gully currently has one HVAS TSP unit and one HVAS PM10 unit located adjacent to the township of Blackmans Flat (Appendix 3). Results from the HVAS TSP and PM10 units are shared by Pinedale Mine and Coal Services/Lamberts Gully. HVAS TSP and PM10 summary results for the period January – December 2013 are shown in Appendix 3.

HVAS TSP results for the period January – December 2013 show an annual average result of 26.2 ug/m

3, which is well below the annual average assessment a criterion of 90 ug/m

3. This is a slight

increase on dust levels from 2012, which recorded an annual average of 24.6 ug/m3.

Similarly, the HVAS PM10 results were also within the required Air Quality Monitoring Program assessment criteria. The average PM10 result was 12.7 ug/m

3 which is considerably lower than the

annual average PM10 assessment criteria of 30 ug/m3. The highest PM10 result recorded during a single

24 hour run day was 85 µg/m3

which was recorded on 18 October 2013, with this being above the 24 hour-maximum criteria of 50 ug/m

3. This increased level of PM

10 corresponded to significant bushfires in

the area.


3.3.3 Green House Gas Emissions

In accordance with Condition 33(c) of the project approval, greenhouse gas (GHG) emissions are monitored on an absolute basis and on a per tonne of coal produced basis. The main source of GHG emissions is the burning of diesel fuel on the site. The operations constantly seek ways of reducing fuel consumption through efficient mine planning and machinery maintenance.

Centennial Coal has statutory reporting obligations for data collected under the National Greenhouse and Energy Reporting (NGER) Act 2007. The data measured under this Act is independently verified by an external auditor prior to submission to Government. This data is collected, audited and reported on a financial year basis and as such is reported externally to any agency on a financial year basis using the most up to date recently audited data.

Greenhouse gas results for Coal Services/Lamberts Gully are recorded as part of the Springvale AEMR.

3.4 Erosion and Sediment Control

Erosion and sediment control is part of the Site Water Management Plan (SWMP). Erosion and sediment control measures that are in place include:

Staging of works;

Controlling access into and within the site;

Management of earthworks;

Maintaining existing vegetation on site;

Minimising erosion of disturbed areas;

Flocculation of dams to reduce TSS;

Where practical progressive rehabilitation of the work areas will be undertaken in accordance with the Mine Closure Plan; and

Contour banks are constructed to reduce runoff velocities and direct runoff into sediment traps and collection ponds before potential discharge.

As outlined in Section 2.9, there were upgrades to erosion and sediment controls at several locations, including near Sediment Dam 2. Photo 8 illustrates an eroded drainage line that has been reshaped near Sediment Dam 2.

Photo 8: Drainage line at Coal Services/Lamberts Gully was reshaped and stabilised in 2013


3.5 Surface Water Management

The upgrades to the site water management system are outlined in Section 2.9. This section outlines surface water monitoring results and flows.

Graphed surface water monitoring results (from LDP006) are presented in Appendix 2.

3.5.1 Review of Water Quality Monitoring Results – LDP006

Coal Services/Lamberts Gully has two licensed discharge points, LDP006 and LDP007, under EPL 3607. Overflow from Cooks Dam discharges directly into LDP006, which discharges into Wangcol Creek.

LDP007 is a sump at the overland conveyor transfer point and usually does not discharge. It did not discharge during the reporting period and hence no monitoring data was collected. There is no discharge limit associated with LDP007 in the EPL.

For LDP006 and LDP007, the concentration of a pollutant discharged at that point, is not to exceed the concentration limits specified for that pollutant in Table 3.8.

Table 3.8: LDP006 and LDP007 Discharge Limits

Table 3.9: Water Quality Monitoring Requirements for LDP006 and LDP007


Table 3.10 presents the minimum, maximum and average values of monitoring data at LDP006. Appendix 2 provides graphs for each of the surface water key parameters that have been measured. Appendix 2 also provides surface water monitoring results for upstream and downstream monitoring locations (total four locations) on Wangcol Creek. This allows a comparison between upstream, LDP006 and downstream monitoring locations.

All oil and grease results were below the detection limit at LDP006, therefore no additional data analysis has been completed.

Surface water discharges from LDP006 must be within the pH range of 6.5 to 8.5 to meet the EPL surface water criteria. The pH for LDP006 during the reporting period ranged from 6.34 to 7.46 with an average of 6.8 (Appendix 2 - Graph 1). The average pH at LDP006 increased from 6.21 in 2012 to 6.8 in 2013. The pH range for the upstream and downstream monitoring locations at Wangcol Creek was 5.97 to 7.94 in 2012 compared 6.56 to 7.79 in 2013. The 2013 results at Wangcol Creek were generally consistent with the pH results at LDP006.


Surface water discharges from LDP006 for Total Suspended Solids (TSS) must be less than 30 mg/L to meet the EPL surface water criteria. TSS results for LDP006 during the reporting period ranged between 2 mg/L and 25 mg/L, with all results therefore being within EPL criteria (Appendix 2 - Graph 2). The average TSS at LDP006 decreased from 22 mg/L in 2012 to 11 mg/L in 2013. The TSS range for the upstream and downstream monitoring locations at Wangcol Creek was 0.6 mg/L to 84 mg/L in 2012 compared to 1 mg/L to 8 mg/L in 2013. The 2013 results at Wangcol Creek were lower than the TSS range at LDP006.

The electrical conductivity (EC) results for LDP006 during the reporting period ranged from 1100 µS/cm to 3180 µS/cm, with an average of 2383 µS/cm (Appendix 2 - Graph 3). The average EC level at LDP006 increased from 1588 µS/cm in 2012 to 2383 µS/cm in 2013. The EC range for the upstream and downstream monitoring locations at Wangcol Creek was 76 µS/cm to 2340 µS/cm in 2012 compared to 237 µS/cm to 3240 µS/cm in 2013. The 2013 results at Wangcol Creek were a greater range than those recorded at LDP006.

Total zinc results for LDP006 during the reporting period ranged from 0.03 mg/L to 0.59 mg/L, with an average of 0.28 mg/L (Appendix 2 - Graph 4). The average total zinc at LDP006 decreased from 0.188 mg/L in 2012 to 0.28 mg/L in 2013. The total zinc levels for the upstream and downstream monitoring locations at Wangcol Creek ranged from 0.005 mg/L to 0.233 mg/L in 2012 compared to 0.005 mg/L to 0.340 mg/L in 2013. The 2013 results at Wangcol Creek were a smaller range than the LDP006 results.

Nickel (filterable) for LDP006 during the reporting period ranged from 0.028 mg/L to 0.334 mg/L, with an average result of 0.223 mg/L (Appendix 2 - Graph 5). The average nickel (filterable) level at LDP006 increased from 0.152 mg/L in 2012 to 0.223 mg/L in 2013. The nickel (filterable) levels for the upstream and downstream monitoring locations at Wangcol Creek ranged from 0.003 mg/L to 0.277 mg/L in 2012 compared to 0.005 mg/L to 0.314 mg/L in 2013. On average the nickel (filterable) levels were higher at LDP006 than at the Wangcol Creek monitoring locations for 2013.

Total hardness results for LDP006 during the reporting period ranged from 316 mg/L to 1290 mg/L, with an average result of 883 mg/L (Appendix 2 - Graph 6). The average total hardness results for LDP006 increased from 575 mg/L in 2012 to 883 mg/L in 2013. The total hardness results for the upstream and downstream monitoring locations at Wangcol Creek ranged from 30 mg/L to 948 mg/L in 2012 compared to 80 mg/L to 1240 mg/L in 2013. The 2013 results at Wangcol Creek were of a similar range to the LDP006 results.

Filterable manganese results for LDP006 during the reporting period ranged from 0.479 mg/L to 9.36 mg/L, with an average result of 3.43 mg/L (Appendix 2 - Graph 7). The average filterable manganese level at LDP006 increased slightly from 3.204 mg/L in 2012 to 3.43 mg/L in 2013. The filterable manganese results for the upstream and downstream monitoring locations at Wangcol Creek ranged from 0.062 mg/L to 2.88 mg/L in 2012 compared to 0.098 mg/L to 3.93 mg/L in 2013. The 2013 results at Wangcol Creek were of a smaller range than the LDP006 results.

Filterable iron results for LDP006 during the reporting period ranged from <0.05 mg/L to 6.1 mg/L, with an average result of 1.21 mg/L (Appendix 2 - Graph 8). The average filterable iron level at LDP006 decreased from 1.74 mg/L in 2012 to 1.21 mg/L in 2013. The filterable iron results for the upstream and downstream monitoring locations at Wangcol Creek ranged from <0.05 mg/L to 5.64 mg/L in 2012 compared to 0.05 mg/L to 0.81 mg/L in 2013. The 2013 results at Wangcol Creek were of a significantly smaller range than the LDP006 results.

3.5.2 Review of Discharge Volume Monitoring Results

Discharge from LDP006 (Appendix 2 - Graph 9) ranged between 0 kL/day and 11,652 kL/day. The total water discharged from LDP006 decreased significantly from 1,040,882 kL in 2012 to 310,585 kL in 2013. There was only one occasion when the discharge limit of 10,000 kL/day was breached, with this occurring on the 1 March 2013.

On the 21 May 2013, the EPL was modified, with the discharge limit of 10,000 kL per day removed. There were no other occasions where the discharge was greater than 10,000 kL for the rest of 2013. Table 3.11 displays a comparison of volume data over the last three years.


Table 3.11: Comparison of Annual Discharge Volumes from LDP006 from 2011 to 2013

2011 2012 2013

Min Flow (kL) 0 0 0

Average Flow (kL)

Max Flow (kL) 53,534 174,029 11,652

Total Flow (kL) 903,360 1,040,882 310,585

As illustrated in Table 3.11, during 2013 there was a large decrease in the amount of water discharged from LDP006, compared to 2012 and 2011. This decrease was primarily related to lower rainfall and the pumping of Cooks Dam water to DML Dam.

3.5.3 Review of Surface Water Monitoring

A review of water quality data over the last four years (Table 3.12) from LDP006 generally shows that 2013 results are comparable to previous years. The largest variations occurred in EC (increase) and TSS (decrease) during 2013.

3.6 Groundwater Management

Additional piezometers were installed at Coal Services/Lamberts Gully in 2013 to gather additional information on water seeping into Cooks Dam. These bores which have been installed into the goafed mine area to enable the calculation of the volume of water that is held in storage. Close monitoring of the water level response to any rainfall events will enable the determination of the amount of infiltration/recharge that the underground workings are receiving.

RPS Aquaterra prepared a Groundwater Assessment for the July 2013 EIS. Overall the impact of the Project on the groundwater system, licensed groundwater users, Wangcol Creek and downstream groundwater dependant ecosystems (GDEs) is considered to be minimal. Increases in groundwater discharge to dams at Coal Services/Lamberts Gully will have a beneficial effect on the existing water quality discharging from site.

The impact assessment has indicated that the existing and future operation of the Western Coal Services Project poses a very low risk to groundwater systems. Additional groundwater monitoring will be undertaken in order to verify the predicted impacts.


3.7 Contaminated / Polluted Land

In February 2012 a letter was sent to the OEH from Centennial to notify them of a contamination site assessment across all of Centennial’s operating sites in NSW to determine the legal obligation to report contamination pursuant to the amendments to the Contaminated Land Management Act 1997. Coal Services/Lamberts Gully was assessed as a low risk site with an additional assessment to be undertaken within the next three years.

A Phase 1 Environmental Site Assessment (ESA) was completed in April 2013 by AECOM for the July 2013 EIS. The Phase 1 ESA concludes that the past and current use of the site is likely to have resulted in potential soil, sediment and surface water contamination, and potential groundwater impact in some areas of the site. AECOM recommends a Phase 2 ESA should be conducted where contamination risk is moderate (see table 3.13).

The ESA outlined that potential contaminants of concern identified from the past and current activities at the site include total petroleum hydrocarbons (TPH) associated with fuel storage; monocyclic aromatic hydrocarbons associated with fuel and solvent storage; polycyclic aromatic hydrocarbons (PAHs) associated with coal waste, lubricating oil and ash from adjacent power station; metals (As, Cd, Cr, Cu, Ni, Hg, Pb, Zn) associated with mine operations; polychlorinated biphenyls associated with historic use of electrical transformers; explosives associated with storage of explosives on site; and asbestos associated with fill material and demolition of former buildings on site.

The results of the qualitative risk assessment indicate that based on the information currently available, the potential contamination at the site presents a very low to moderate risk to human health and the environment. A summary of the risk ranking outcomes is provided in Table 3.13.

3.8 Threatened Flora

An ecological assessment was completed by RPS as part of the preparation of the July 2013 EIS for the Western Coal Services Project. The ecological assessment extends well outside the Coal Services/Lamberts Gully site and includes consideration of vegetation adjacent to the haul roads, Lidsdale Siding, Wangcol Creek and Ben Bullen State Forest.


The total Coal Services site/Lamberts Gully site is approximately 287 hectares and can be described as follows:

51% of the site is cleared and severely disturbed, being mined/worked land;

24% of the site is planted/regenerated vegetation – previously mined areas;

24% of the site is relatively un-disturbed native vegetation; and

Less than 1% of the site is pine plantation.

Targeted threatened flora surveys by RPS for the July 2013 EIS identified one threatened flora species within the site, namely E. Aggregate, which is listed as Vulnerable under the TSC Act 1995. No additional threatened flora species were recorded on site during the preparation of the July 2013 EIS. Only five E. aggregata trees were found in the Tablelands Gum – Peppermint woodland to the east of the dam that occurs within Lamberts Gully. This area was cleared in January 2007. The trees were felled and left for seed harvesting prior to being windrowed. Over half a kilogram of seed was harvested and some has been used in seeding of the rehabilitation program and some has been retained for future use.

E. aggregata is outside the REA and is not likely to be impacted upon as a result of the proposed activities. Surveys within the site did not detect any further threatened flora species, however two are considered to have potential to occur, namely, E. cannonii and T. australe.

3.9 Threatened Fauna

An ecological assessment was completed by RPS as part of the preparation of the July 2013 EIS for the Western Coal Services Project. The results of database searches indicated that 42 threatened fauna species have been previously recorded within 10km of the site (the locality) and/or have potential habitat within the site.

Eleven species of microchiropteran bat were positively identified from Anabat echolocation call recording within the site. Of these, four species are listed as threatened under the TSC Act 1995. These included the Chalinolobus dwyeri (Large-eared Pied Bat), Falistrellus tasmaniensis (Eastern Falsistrelle), Miniopterus schreibersii oceanensis (Eastern Bent Wing Bat) and Saccolaimus flaviventris (Yellow Bellied Sheathtail Bat).

The upgrade project is expected to result in the removal of approximately 10.67 ha of forest based upon the preferred Link Haul Road option (Link Haul Road Option 2). The surrounding state forests provide large areas of consolidated habitat for common and threatened fauna considered to have potential to occur within the locality. Whilst the removal of the vegetation on site is deemed to constitute a loss of habitat for threatened fauna, given the large amounts of neighbouring habitat, the proposal is not considered to constitute a significant reduction of habitat to locally occurring fauna.

3.10 Weeds

The major weed threats include Blackberry (Rubus fruticosus), St. Johns Wort (Hypericum perforatum) and Pampas Grass (Cortaderia selloana), which are controlled by the annual noxious weed control program.

There are very few established weeds in the Lamberts Gully Rehabilitation areas. Weed spraying was completed during 2013, targeting Blackberry, and will continue in 2014.


3.11 Operational Noise

3.11.1 Noise Monitoring Program

In accordance with Condition 5 of Schedule 3 of the Project Approval, a Noise Monitoring Program was submitted to the then Department of Planning (DoP) on the 14

th August 2006. Following consultation

with the then DoP, the Program was revised and resubmitted on the 25th September 2006 and approved

by the Director General on the 13th December 2006. The Noise Monitoring Program has been fully

implemented.

As set out by the Project Approval and EPL and specified in the Noise Monitoring Program, noise generated by the project must not exceed the noise impact assessment criteria presented in Table 3.14 below:

Noise monitoring locations are shown in Drawing 2 of Appendix 3 (Air Quality, Noise and Meteorological Monitoring Report).

3.11.2 Noise Monitoring Compliance Assessment

Noise monitoring for Coal Services/Lamberts Gully is undertaken in accordance with the Noise Monitoring Program at two key locations. Previously, noise monitoring had been conducted at the Tailings Dam site; however in 2013 the monitoring site was changed to Residence R2, to enable background monitoring to continue without the need to enter the Lamberts Gully Mine site. It should be noted that residential monitoring site R2 is located approximately 53m to the NNE of the Tailings Dam monitoring site.

In previous years, noise monitoring at Coal Services/Lamberts Gully has been carried out at several different locations including the Blackmans Flat residential monitoring locations (R1- R7), the tailings dam site (TD2), and also at Lamberts Gully Pit Top monitoring site (LGP).

Previous monitoring results have shown that monitoring undertaken at each of the residential locations is not representative of the noise generated from the Coal Services/Lamberts Gully operations, due to the dominance of other ambient noise sources present at these locations, namely the Castlereagh Highway.

During the 2013 period, bi-monthly monitoring was conducted when possible (weather permitting) at the R2 and R7 sites in order to obtain background noise data whilst mining operations were not occurring.

During 2013 routine bi-monthly attended noise monitoring was undertaken during the following periods:

February – monitoring at R2 and R7 undertaken on 20 February 2013;

April – monitoring at R2 and R7 undertaken on 22 April 2013;

June – monitoring at R2 and R7 undertaken on 24 June 2013 and 25 June 2013;

August – monitoring at R2 and R7 undertaken on 26 August 2013; and


October – monitoring at R2 and R7 undertaken on 30 October 2013.

Noise monitoring for the December 2013 bi-monthly period is scheduled to be conducted in mid-January 2014.

A detailed analysis of the noise monitoring results and a figure showing location of noise monitoring stations is presented in Appendix 3. In summary, operational attended noise monitoring results for the period January – December 2013 are not directly comparable to the noise impact assessment criteria stipulated in Noise Monitoring Program as the mine was not operational during this period. The results, however, are useful in that they provide a true measure of the background noise levels in the area.

When these background noise results are compared to the noise impact assessment criteria for noise monitoring sites R2 and R7 it can be seen that exceedances are still shown to occur even when the mine is not operational. This implies that the noise impact assessment criteria initially set for the Lamberts Gully Mine are not practically achievable, even during periods of non-operation.

During the reporting period, Coal Services/Lamberts Gully received no noise complaints.

3.11.3 EIS Noise Assessment

SLR Consulting completed the Noise and Vibration Impact Assessment for the July 2013 EIS. The predicted noise emission levels indicate that many noise receivers modelled will meet the Project Specific Noise Criteria established for the upgrade project. However, the results of the Noise and Vibration Impact Assessment indicate that there will be likely residual noise impacts above the Project Specific Noise Criteria at some of the receptors at Blackmans Flat. A specific Noise Management Plan would be developed upon approval of the July 2013 EIS, with this management plan to outline the specific noise monitoring requirements and noise management strategies for the site.

3.12 Blasting

With mine production ceasing during 2010, there was no blasting undertaken during the reporting period. It should be noted that Pinedale has conducted blasting during the reporting period.

3.13 Visual Stray Light

Visual stray light is not considered to pose any potentially adverse environmental impacts at the mine due to surface footprint, locality, and the distance to neighbouring properties. There have been no complaints received in the operating life of the mine in relation to visual stray light.

Visual impact was assessed for the July 2013 EIS. Whilst the visual impact of the upgrade project will be considered moderate, the visual absorption capacity of the area is relatively high in relation to coal handling and coal infrastructure. Consequently, it is considered that the cumulative visual impact is considered minor to moderate.

There are predicted to be no changes to visual impact at Coal Services/Lamberts Gully in 2014.

3.14 Aboriginal Heritage

A Cultural Heritage Assessment was completed by RPS as part of the July 2013 EIS.

A total of 17 registered sites have been identified at the Coal Services/Lamberts Gully site. Of these sites, eight (47.5%) have been salvaged under a Section 90 Aboriginal Heritage Impact Permit, which means that 52.5% of all known sites remain. With the relevant approvals, there is an opportunity to salvage the six newly recorded sites (isolated finds) in the Coal Services/Lamberts Gully site, reducing the total number of sites remaining to three (17.6%).


The Cultural Heritage Assessment notes that isolated finds are a common occurrence in the landscape which cannot be contextualised or associated with an assemblage to develop an understanding of the subsistence activity once associated with the artefact. Given that the six newly recorded sites were identified in a highly modified and/or disturbed landscape, the value of these sites has also been assessed as low.

There are no cumulative impacts or foreseeable risk of harm to Aboriginal or non-Aboriginal Heritage due to the Project.

3.15 European Heritage

There are no identified areas of European heritage at Coal Services/Lamberts Gully.

3.16 Spontaneous Combustion

Spontaneous combustion from coal processing and stockpiling at Coal Services is considered as a low risk. The mined coal seams have a low propensity for spontaneous combustion with no spontaneous combustion issues in relation to in-situ or for processed coal. The highest risk of spontaneous combustion appears to be when stockpiling remains for greater than approximately 1 to 2 years. Coal sent to Coal Services is generally stockpiled for less than 1 year. There have been no incidences of spontaneous combustion in the life of the Coal Services/Lamberts Gully site.

3.17 Bushfire

No controlled burns were carried out during the reporting period and there were no bushfires onsite.

The risk of bushfire being increased by the site activities is low at Coal Services/Lamberts Gully, as the local ecology is adapted to fire and robust bushfire management protocols are in-place, and bushfire management included in the Emergency Management System.

The largest risk comes from bushfires emanating from the Ben Bullen State Forest. This forest is managed by the Forestry Corporation of NSW. Firebreaks have been established along the overland conveyor where it passes through forested land. The main assets on site are adequately protected by existing cleared land.

A Bushfire Management Plan has been prepared for Coal Services/Lamberts Gully with this plan outlining:

Emergency procedures and numbers;

Firefighting equipment;

Management of flammable materials;

Training; and

Water sources for firefighting.

3.18 Mine Subsidence

Surface inspections have identified subsidence areas across the mining lease as the site is above historic underground workings. Previously where subsidence has been found which requires remediation the area is shaped, contour drains established, top-dressed and sown.

During 2013 there were no new subsidence areas identified or repairs completed.


3.19 Methane Drainage/Ventilation

The previous underground mining operations completed in the Lamberts Gully/Coal Services area have not caused any issues relating to methane drainage/ ventilation. Since Centennial has managed the open cut operation the site has had no issues regarding methane drainage/ ventilation. Neighbouring underground operations in the Lithgow region have not recorded any issues relating to methane drainage/ ventilation.

3.20 Public Safety

Public safety risks associated with the Coal Services/Lamberts Gully are largely from public trespass on land around the open cut area. The site is sign posted and regularly patrolled by a contract security service. The site is surrounded by a large perimeter fence.

During the reporting period, fencing had to be repaired on numerous occasions due to vandalism.

3.21 Other Issues and Risks

No other environment or community risks have been identified during the 2013 Broad Brush Risk Assessment process.

3.22 Summary of Compliance

Heavy rainfall on 1 March 2013 resulted in a discharge from LDP006 of greater than 10,000kL per day (total 11,652 kL). On the 21 May 2013, there was a variation to the EPL, with the discharge limit of 10,000 kL per day removed. There were no other occasions where the discharge was greater than 10,000 kL for the rest of 2013.

There were two occasions during 2013 (1 March and 4 July) when the water sample taken at LDP006 was below the EPL pH criteria of 6.5 (result pH 6.34 on 1 March 2013 and pH 6.48 on 4 July 2013). There were no exceedances of TSS or oil and grease from LDP006 during the reporting period.

The above non-compliances relating to volume discharge and the pH exceedances from LDP006 will be reported in the Annual Return.


4 COMMUNITY RELATIONS

4.1 Environmental Complaints

There were no community complaints relating to Coal Services/Lamberts Gully during the reporting period.

4.2 Community Liaison

A Community Consultative Committee (CCC) was formed and ran under the terms of the Lamberts Gully Coal Mine approval. The CCC was officially closed in 2011, following consultation and approval with the Department of Planning and Infrastructure.

Centennial Coal is in the process of establishing a Centennial Western Sites CCC. Letters were sent out to the local community (Wallerawang area) requesting those to register interest in joining the Centennial Western sites CCC. The Centennial Western CCC will be established in 2014.

Community engagement was completed as part of the July 2013 EIS for the Western Coal Services Project. Section 6 of the July 2013 EIS provides details on community consultation, including:

Community Information sessions;

Letter box-drop of leaflets;

A series of articles and advertisements in the local paper;

Direct engagement with residents in the main residential area of Blackmans Flat; and

Meetings with key government stakeholders including the DP&I.


5 REHABILITATION

A Rehabilitation and Mine Closure Risk Assessment was completed for Coal Services/Lamberts Gully in March 2010 to identify and scope the risks associated with rehabilitation and mine closure.

Prior to the risk assessment, aspects and categories were entered into the risk assessment spreadsheet based on the key steps in the Rehabilitation and Closure Costs spreadsheet. Based on these aspects, a detailed rehabilitation and closure methodology was developed, with risks and existing controls recorded by the risk assessment team. The risk assessment team then recommended additional controls to effectively manage the risks associated with rehabilitation and closure of the site. The Mine Closure Plan will be updated following approval of the July 2013 EIS.

5.1 Buildings

On the completion of mining in June 2010, several portable buildings associated with mining were removed. During the reporting period, there were no permanent buildings renovated or removed.

5.2 Rehabilitation of Disturbed Land

Currently there are minimal areas available for rehabilitation, due to areas being used for operational purposes. Where areas are available, a rehabilitation seed mix will be used that is similar to a native forest ecosystem which surrounds the site. This does not include the area to the north which is required for additional ash emplacement by Energy Australia and to accommodate the LCC Waste Emplacement Facility.

Appendix 6, Figure 3 illustrates the layout of the mining blocks at Lamberts Gully.

Reject Emplacement Area (REA)

Access to the REA will remain open for the remaining life of the Washery and these areas will remain the responsibility of Coal Services/Lamberts Gully to both manage and rehabilitate. There was no rehabilitation of this area in 2013, with none planned for 2014. The July 2013 EIS outlines plans to expand the REA.

Council Waste Facility and Energy Australia Ash Emplacement Facility

Separate access to both the Council Waste Disposal Facility and the Ash Emplacement Area will be developed in consultation with both LCC and Energy Australia. Once completed, these areas will become the responsibility of LCC and Energy Australia respectively to both manage and rehabilitate.

During 2013, Energy Australia constructed a new ash emplacement facility on Energy Australia owned land. Specific aspects of the ash emplacement facility are outlined in the Environmental Assessment (August 2010), which was approved by the DP&I on 16 February 2012 (PA09_0186).

5.3 Other Infrastructure

There was no other infrastructure available for removal during the reporting period. All established infrastructure is required for the continued operations of the Washery.


5.4 Rehabilitation Trials and Research

AECOM Pty Limited (AECOM) was again engaged to undertake rehabilitation monitoring at Coal Services/Lamberts Gully during the 2013 reporting period. This is the fourth year of ecosystem function analysis (EFA) monitoring for Coal Services/Lamberts Gully. Monitoring was undertaken at eight monitoring transects, comprising three analogue transects (CSV A1 to CSV A3) and five rehabilitation transects (CSV R1 to CSV R5). Transects CSV A1, CSV R1, CSV R2 and CSV R3 were established in 2010, transects CSV A2 and CSV A3 were established in 2012, and transects CSV R4 and CSV R5 were established in 2013.

Permanent transects and associated photo reference sites were established in areas of post-mining rehabilitation and correspondingly in adjacent undisturbed areas to provide analogue/reference sites. The analogue sites are selected to represent as close as possible the proposed vegetation characteristics of the rehabilitation and revegetation areas. The analogue sites also provide data on the long-term goal for the rehabilitation areas. Analogue and rehabilitation monitoring locations are outlined in Figure 1. Table 5.1 summarises rehabilitation monitoring results at Coal Services/Lamberts Gully during the reporting period. Figure 2 and 3 shows the Soil Surface Condition Indices (SSCI) at Coal Services/Lamberts Gully over the 2010-2013 monitoring period for rehabilitation monitoring sites and analogue monitoring sites.

Summary of Rehabilitation Monitoring Sites

New rehabilitation monitoring sites (CSV R4 and R5) were added in 2013 to the rehabilitation monitoring program. As these sites (CSV R4 and R5) have only recently been added, there is no comparison data from previous years of rehabilitation monitoring. In summary:

CSV R1

Stability – decrease from 49% in 2012 to 41% in 2013.

Infiltration – increase from 19% in 2012 to 25% in 2013.

Nutrient Cycling – no change with 13% in 2012 and 2013.

CSV R2



Nutrient Cycling – increase from 17% in 2012 to 19% in 2013.

CSV R3

sourced from the licensee’s underground workings, through licensed discharge points 4 (LD4) and 5

(LD5) in the event of a shutdown of the Springvale Colliery to Delta Water Transfer Scheme for

circumstances either beyond the licensee’s control or for essential maintenance purposes.

E1.2 Prior to discharge:

The licensee must ensure that appropriate measures are taken prior to any emergency water discharge to

minimise erosion and sedimentation at the discharge points (LD4 and LD5) and of the drainage lines

downstream of LD4 and LD5.

E1.3 Notifying the EPA of emergency discharge

The licensee shall inform the EPA in writing (fax to 6332 7630):

a) within 24 hours of a failure in the Springvale to Delta Water Transfer Scheme;

b) no later than 48 hours prior to a scheduled pipeline shutdown;

c) no later than 48 hours prior to the requirement to continue the emergency discharge for a period

greater than 2 weeks; and

d) within 24 hours following the reinstatement of the pipeline.

The notification of a failure or planned shutdown of the pipeline must include details of the nature of the

failure/shutdown and the expected timeframe to restore the pipeline.

E1.4 Monitoring during emergency discharge

In addition to the monitoring required by condition M2.1, the licensee shall undertake the following

monitoring during and following an emergency discharge event:

a) daily inspections of the discharge points (LD4 and LD5) and the drainage lines downstream of LD4 and

LD5;

b) daily monitoring (visual) of the equilibration of the flow rate between emergency discharge points LD4

and LD5; and

c) a photographic survey along the length of the flow lines, beneath the discharge points, likely to be

affected during periods of emergency discharge. This survey must be conducted either immediately prior

to or during the emergency discharge event and no later than 6 months following the cessation of the

emergency discharge event.

E1.5 Emergency discharge reporting




A report shall be prepared by the licensee, following the recommissioning of the pipeline, which shall

include but not be limited to:

a) the cause of the pipe failure/shutdown;

b) the duration of the emergency discharge (in days);

c) the total volume of water discharged from LD4 and LD5 (in kL/day);

d) the results of all monitoring undertaken;

e) any remedial measures required on the drainage line(s) below the emergency discharge points that

have been or will require implementation;

f) any measures to be taken to prevent a recurrence in the case the emergency discharge event was a

result of a pipe failure; and

g) all appropriate photos and figures.

The report must be sent to the EPA’s Bathurst office within four (4) weeks of the recommissioning of the

Springvale to Delta Water Transfer Scheme.

Option Study to treat Mine Water DischargeE2

E2.1 The licensee must prepare and submit to the EPA for review, a report outlining options to treat ground

water (mine water) generated by the licensed premise as a result of mine dewatering activities, prior to

any discharge to the environment.

The objective of the option study is to reduce salt load and salinity levels discharged into the Coxs River

Catchment by the licensee. The options or option identified must be capable of treating all mine water

generated by the premises (ground and surface water) to achieve an electrical conductivity (EC) of 350

microsiemens per centimetre in the treated water, prior to the treated water being discharged to the Coxs

River or any of its tributaries. Where appropriate, the treatment of other pollutants in the discharge must

be assessed.

Where the option study proposes a water treatment option that involves Delta Electricity, the option must

be developed in consultation and agreement with Delta Electricity.

Completion Date: The option study and report must be submitted to the EPA by 30 September 2013.

1 GENERAL COMMENTS

The following report provides a summary of monthly environmental monitoring data for the Lamberts Gully Mine for the year 2013. Summary data is comprised of High Volume Air Samples (TSP & PM10), Depositional Dust, and Environmental Noise monitoring.

A compliance assessment of both depositional dust results and High Volume Air Sample (HVAS) results is made in accordance with the criteria presented in the Lamberts Gully Coal Mine Air Quality Monitoring Program.

Similarly, a compliance assessment of the routine noise monitoring results is undertaken in accordance with the criteria presented in the Lamberts Gully Coal Mine Noise Monitoring Program.

2 ASSESSMENT CRITERIA

2.1 DEPOSITIONAL DUST AND HVAS PARTICULATE MATTER ASSESSMENT CRITERIA

The Air Quality Monitoring Program stipulates that dust emissions generated by the project must not cause additional exceedances of the long term impact assessment criteria listed in Table 1, 2 and 3.

3 ANNUAL DATA SUMMARY: JANUARY – DECEMBER 2013

3.1 METEOROLOGICAL MONITORING RELATING TO AIR

Lamberts Gully receives continuously recorded meteorological data via a data sharing agreement with nearby Pine Dale Mine, which has a meteorological monitoring station located on-site. Parameters recorded (at 10-minute intervals) include wind speed, wind direction, temperature at 10m height, temperature at 2m height, and rainfall. Additional sensors to record humidity, solar radiation, sigma theta and evapotranspiration were installed on 22 May 2013.

Data capture from the weather station during the January to December 2013 period was 99.96%.

Details of weather data recorded for the period January to December 2013 are presented in Appendix B.

3.2 DEPOSITIONAL DUST DATA SUMMARY

Lamberts Gully Coal Mine currently has 3 depositional dust gauges. Two of these gauges are located within the township of Blackmans Flat, whilst the third gauge is located to the south of Blackmans Flat (refer Drawing 1- Appendix A). Data from Gauge D1 & D2 is shared by Pine Dale Mine and Springvale Coal – Lamberts Gully Coal Mine. Dust Gauge D3 is owned solely by Springvale Coal.

3.4 METEOROLOGICAL MONITORING RELATING TO NOISE MONITORING

In addition to the continuous data recorded by the meteorological monitoring station, local wind speed and wind direction at ground level, and cloud cover (%) is measured prior to the start of each 15-minute attended noise survey.

3.5 NOISE MONITORING RESULTS SUMMARY

Noise monitoring for the Lamberts Gully Coal Mine is undertaken in accordance with the Lamberts Gully Coal Mine Noise Monitoring Program M82 V2.0, 2008. During the 2013 period, bi-monthly monitoring was conducted when possible (weather permitting) at two residential monitoring sites R2 and R7. The purpose of the noise survey was to obtain background noise data whilst mining operations were not occurring.

Previously, noise monitoring had been conducted at the Tailings Dam site; however, the monitoring site was changed to Residence R2 at the request of Mr Rob Hunt (Centennial), to enable background monitoring to continue without the need to enter the Lamberts Gully Mine site. It should be noted that residential monitoring site R2 is located approximately 53m to the NNE of the Tailings Dam monitoring site. Refer to Drawing 2, Appendix B for noise monitoring locations.

10


During 2013 routine bi-monthly attended noise monitoring was undertaken during the following periods:

February – monitoring at R2 and R7 undertaken on 20/02/13.

April – monitoring at R2 and R7 undertaken on 22/04/13.

June – monitoring at R2 and R7 undertaken on 24/06/13 & 25/06/13.

August – monitoring at R2 and R7 undertaken on 26/08/13.

October – monitoring at R2 and R7 undertaken on 30/10/13.

December – see note.

Note - noise monitoring for the December 2013 bi-monthly period is schedule to be conducted in mid-January 2014.

Results of bi-monthly attended noise monitoring are shown in Table 7. Results compared to the Noise Impact Assessment Criteria are shown in Table 8.

4 COMPLIANCE ASSESSMENTS

4.1 4.1 AIR QUALITY MONITORING COMPLIANCE ASSESSMENT

4.1.1 Depositional Dust Results

Depositional Dust results for the period January – December 2013 show an average insoluble solids result of 1.6g/m2.month for dust gauge D1; 0.7 g/m2.month for gauge D2; and 1.1 g/m2.month for gauge D3. These results fall well below the nominated annual average assessment criteria of 4.0g/m2.month, as stipulated in the Air Quality Monitoring Program.

An elevated result (9.5g/m2.month) was recorded at D1 during December 2013. An investigation of the sample indicates that organic contamination contributed heavily to the insoluble solids result with a combustible matter to insoluble solids ratio of 87%. This shows that only 13% of the sample consisted of inorganic (potential deposited dust) material. The field sheet indicates that insects were present and therefore are the likely contamination source. Despite this high result, the annual average at this monitoring location is still considered low, with a result of 1.6g/m2.month.

4.1.2 HVAS Particulate Matter Results

HVAS Total Suspended Particulate (TSP) results for the period January – December 2013 show an annual average result of 26.2g/m3; which is well below the annual average TSP assessment criteria of 90g/m3. During the reporting period there were six run events in which a programming error caused the TSP unit to run for greater than the quality assurance period of twenty four hours ± one hour as stipulated in AS3580.9.3.

15


The HVAS particulate matter results <10m (PM10) also show levels which are within the required Air Quality Monitoring Program assessment criteria. The annual average PM10 result was 12.7g/m3 which considerably lower than the annual average PM10 assessment criteria limit of 30g/m3. There was one exceedence of the OEH’s short term 24hour maximum criteria of 50g/m3 for PM10 particulates during the reporting period with a concentration of 85µg/m³ measured. This exceedence occurred on the 18 October 2013 during a period when severe bushfires, including the “State Mine Fire”, were present in and around the Lithgow area.

During the reporting period there were two run events in which a programming error caused the PM10 unit to run outside of the quality assurance run period of twenty four hours ± one hour as stipulated in AS3580.9.6.

4.2 NOISE MONITORING COMPLIANCE ASSESSMENT

Operational attended noise monitoring results for the period January – December 2013 are not directly comparable to the noise impact assessment criteria stipulated in the Lamberts Gully Coal Mine Noise Monitoring Program as the mine was not operational during the 2013 period. The results, however, are useful in that they provide a true measure of the ambient noise levels present at each monitoring location.

When these ambient noise results are compared to the noise impact assessment criteria for noise monitoring sites R2 and R7 it can be seen that exceedances are still shown to occur even when the mine is not operational. This indicates that during periods when the Lamberts Gully mine is not operational, the noise impact assessment criteria is exceeded at the Blackmans Flat residences. The influence of the nearby Castlereagh Highway is considered to have a much greater impact upon the noise levels received at the Blackmans Flat residences than the noise emissions generated by the Lamberts Gully mining operations.
