2. INTRODUCTION

Charbon Colliery (Charbon) was an underground (bord and pillar) and open-cut coal mine owned and operated by Charbon Coal Pty Limited, a joint venture between Charbon Coal Pty Ltd Pty (95 percent) and SK Networks Resources Australia Pty Ltd (5 percent). After over 90 years of mining, Charbon has depleted its coal reserves and ceased mining in 2014. Charbon is currently focused on rehabilitation of the site and is working with state agencies to develop and implement the required plans for effective mine closure.


8 of 110

The Charbon Colliery site is located in the Western Coalfields of NSW, approximately 87 kilometres north-west of Lithgow and 3 kilometres south of Kandos (refer to

Figure 1).

The Colliery has been in operation since the 1920’s and initially supplied coal for the former Charbon Cement Works until its closure in 1977. The mine continued to produce coal for local consumption until the Colliery was upgraded in 1985.


9 of 110

The area of Charbon Colliery is 2,692ha. Mining operations prior to closure included six open cut mining areas, two underground mining areas, rail loop & loading facilities, and a coal handling and processing plant (CHPP). Additionally, Charbon also has two onsite Compensatory Habitat Areas (refer to Figure 2). Mining Lease boundaries for Charbon are presented in Figure 3.

6.1. NOISE

Noise monitoring is conducted quarterly to measure the ambient noise levels at the focus receptor locations (potentially worst affected) surrounding the mine and coal handling facilities in accordance with Schedule 3 Condition 1 of Project Approval 08_0211 and Condition L5.1 of EPL528, shown in Table 17 below.

Quarterly noise surveys comprise of operator attended monitoring in 15 minute intervals coinciding with day, evening and night-time periods. Evening and night monitoring was not conducted during the Q1, Q2 and Q3 reporting period as no activities were occurring on site during these time periods. Statistical indices recorded include LAmax, LA1, LA10, LA90 and LAeq. The results of noise monitoring conducted at Charbon during Q1 (March), Q2 (June), Q3 (September) and Q4 (December) 2016 are shown below under the relevant sub-headings. The location of the focus receptors is provided in Figure 45.

All locations at all times during Q4 (December) 2016 were compliant. A summary of noise monitoring results, consent conditions and compliance with consent conditions, can be seen in the Table 27 below.

Table 27 Noise Monitoring Q4 (December) 2016 – Summary of Compliance

In accordance with Schedule 8 Condition 8c the annual review shall report on the investigations and implementation on the effectiveness of noise controls. During the reporting period there were no exceedances of the noise criteria therefore current noise controls installed are considered to be effective in mitigating noise impacts.

6.1.4 HISTORIC NOISE MONITORING RESULTS

Charbon Colliery noise monitoring data from 2012-2015 have been graphically compared to the 2016 noise monitoring results. Locations L and P are the only two remaining locations at Charbon that are not subject to Negotiated Agreements.

Overall, there is generally a slight trend in higher noise readings during 2016 compared to previous years. Although readings are slightly higher than previous years, noise monitoring reporting did not identify the mine as contributing any noise to these receivers during the 2016 monitoring period. Futhermore, no mining operations were occurring during the 2016 reporting period at Charbon.

6.2. BLASTING

Blasting did not occur at Charbon during the 2016 reporting period. Blasting commenced at Charbon in November 2006 and occurred periodically until 2010, with the last blast occurring on 20 August 2010. Blast monitoring and compliance results for Charbon Colliery can be found within previous Annual Reviews.

6.3. AIR QUALITY

Operations at Charbon Colliery are undertaken to minimise the generation of airborne dust. Water trucks continually operate during adverse weather conditions to ensure that dust from workings and haul roads is controlled. Soil handling is undertaken, whenever possible, during times when there is little or no wind.


39 of 110

Schedule 3, Condition 19 of PA 08_0211 requires that the air pollution generated by the development does not exceed the criteria listed in Table 28. Schedule 3, Condition 22 of PA 08_0211 requires High Volume Air Sampler (HVAS) and depositional dust monitoring.

PA 08_0211 limits are adopted as the impact assessment criteria in the Air Quality Management Plan (AQMP).

The Air Quality Monitoring Program at Charbon Colliery consists of the following:

• Six dust deposition gauges;

• One on-site Automatic Weather Station (AWS);

• One HVAS (measuring Total Suspended Particulate [TSP] matter and Particulate Matter <10µm [PM10]).

6.3.1 DEPOSITIONAL DUST MONITORING RESULTS – 2016

Depositional dust (g/m2/mth) results (insoluble solids) for 2016 are shown in Table 29 below. Monthly depositional dust (g/m2/mth) results for 2016 are shown in graphically in Figure 16.

EPL 528 does not include a licence limit for depositional dust, however a rolling average air quality criteria of 4 g/m2/mth is commonly used for comparison purposes. All depositional dust results for 2016 are in compliance with Charbon’s annual depositional dust consent condition limits.

Detailed monitoring results are described in monthly environmental data reports published on the Charbon Colliery website. Depositional dust gauge monitoring locations are shown in Figure 45.

7.1.1 HISTORIC SURFACE WATER RESULTS

Annual surface water quality results for pH, TSS, Turbidity, EC and Oil & Grease form 2012 to 2016 have been graphically represented below. These comparisons are calculated from the annual average result for each water quality parameter during discharge events. Gaps in data are due to nil discharge during that period or data not being required under EPL528 at that point in time.

LDP004, LDP005 and LDP006 were only added to EPL528 in October 2014; Turbidity was also added at this time.

Figure 41 Groundwater Electrical Conductivity data 2015-2016

The groundwater quality at PB2 and PB3 is typical of groundwater within the Shoalhaven Group. This rock formation was deposited in a marine environment and therefore the quality is brackish to saline and the chemistry is very hard and magnesium/calcium – sulfate dominant. Some metals are naturally elevated. No trends in groundwater quality at PB2 and PB3 are evident for most parameters.

8. REHABILITATION

In accordance with the requirements of PA 08_0211 and relevant mining tenements, Charbon is required to rehabilitate the site to the satisfaction of the Department of Industry – Division of Resources and Energy (DRE). Following the cessation of mining in 2015 Charbon has now entered a closure and rehabilitation phase.

There were no building removed from the site during the reporting period.

The Stoney Creek Rehabilitation project commenced during 2016, which included the rehabilitation of 3Ha. This project is scheduled to be completed in 2017.

No rehabilitation trials were conducted during the reporting period. An overview of rehabilitation status is presented in Section 8.1.

8.1. Rehabilitation Monitoring

A Baseline Rehabilitation Monitoring Report has been designed and undertaken to monitor the achievement of rehabilitation progress against the objectives/criteria for the Charbon Colliery Closure Mining Operations Plan (MOP).

The 2016 baseline rehabilitation monitoring report provides an overview of the current status of Charbon rehabilitation sites, a comparison with control sites consummate with the surrounding landscape, and published benchmark data for the target rehabilitated plant community (PCT 863). Measurements of ecosystem composition, landform structure and soil surface characteristics were made at each rehabilitation site and will be used to track performance over the life of the rehabilitation and monitoring program. Currently, all rehabilitation sites appear to be stable with various levels of vegetation growth. At this early stage of rehabilitation monitoring, it is not clear how rapid natural

including land surface stability and drainage performance. Each site is also free from

hazardous or polluting materials. The ecosystem health completion criteria have been

met at CHR 2; however the ecosystem composition and structural characteristics have

not yet progressed sufficiently to be considered complete. The remaining rehabilitation

sites are relatively young and therefore have not progressed enough to satisfy MOP

completion criteria for Domain B - Forest Rehabilitation. These ecosystem characteristics

that remain incomplete are all linked to age of vegetation and ecosystem complexity.

Overall, rehabilitation at all rehabilitation monitoring sites is progressing and showing

early stages of native woodland regeneration. Again, CHR 2 is much further advanced in

ecosystem functioning than other rehabilitation sites. Assuming that the native vegetation

that is currently established at rehabilitation sites continues to grow and become

established (with subsequent seeding and regeneration), and associated improvements

in soil function, it is likely that the ecosystem composition and structure will progress

further towards completion criteria over coming years

A summary of the performance of rehabilitation monitoring sites against the control sites ecological targets and MOP completion criteria are provided in Table 36 below.

8.2. Next Reporting Period

Rehabilitation works are planned to be completed on Privately Owned Land at Charbon in the three areas specified below:

• Area 1 – Southern Open-cut Extension (14ha)

• Area 2 – Southern Outlier (16.9ha) Area 3 – Western Outlier (3.7ha)

During 2016 these lands were prepared for rehabilitation activities to commence Quarter 1 2017. Charbon Coal intends to return 3 ha of privately owned land (Stoney Creek) to the landholder in 2017 Each of these three areas requires a combination of material movement options noted below, followed by comprehensive revegetation works:

• A. Re-contouring Reshaping of mine overburden areas required to reduce both the height of dumps and steeper grades, to allow final rehabilitation activities to occur.

• B. Overburden material movement Overburden material movement to construct the design final landform is required. Suitable mine compliant machinery will be utilised for safe efficient material movement.

• C. Soil material movement Topsoil/subsoil strategic material movement from stockpile source is required to final location or subsequent spread on final landform.

• Revegetation works Final trim, drainage works and seedbed preparation will be completed with subsequent fertilizing and seeding.

9. ENVIRONMENTAL MONITORING

9.1. Aquatic Ecological Monitoring

Charbon undertakes Aquatic Ecological Monitoring bi-annually at serval control and impact locations in waterways associated with Charbon Colliery. A Baseline Aquatic Ecological Monitoring report was sampled during Spring 2015 and Autumn 2016 to establish a baseline reference for monitoring the effects of rehabilitation activities on receiving waters.

Water quality, sediment quality and macroinvertebrate samples have been taken and compared to baseline in accordance with Charbon Colliery’s Water Management Plan.

A total of 40 macroinvertebrate families were in spring 2016. Overall, Diptera (flies) were

the dominant taxa contributing approximately 25% of the total taxa. This was followed by

Odonata (dragonflies and damselflies; 19%), Hemiptera (true bugs; 11 %) and

Ephemeroptera (mayflies; 9%) (refer Figure 42).

Figure 42 Community composition of macroinvertebrate orders for Charbon sites surveyed in spring 2016

Taxa richness, EPT richness, and average SIGNAL-2 scores for each site are presented in Figure 43.


72 of 110

Figure 43 Taxa richness, EPT richness and average SIGNAL-2, spring 2016

The highest taxa richness observed in a macroinvertebrate sample was 23 at RYLR

(refer Figure 43). The next highest taxa richness was observed at DAM1, followed by

RILEY and RECD. EPT richness was highest at DAM1, with four EPT taxa observed,

and lowest at RILEY, where two EPT taxa were observed. Average SIGNAL-2 scores did

not vary greatly between replicates or sites, ranging from 3.12 at RECD to 3.56 at DAM1.

Figure 44 Number of sensitive taxa in macroinvertebrate samples, spring 2016

The numbers of sensitive taxa recorded at each site in spring 2016 are presented in Figure 44. The most sensitive taxa were observed at DAM1, where four sensitive taxa were observed in each replicate. All other replicates contained either two or three sensitive taxa.


73 of 110

9.2. Terrestrial Ecological Monitoring

Terrestrial Flora and Fauna monitoring surveys were undertaken during December 2016 at existing predetermined locations within the northern and southern Compensatory Habitat Management Areas (CHMAs).

Flora surveys comprised BioMetric Plots (n=12), two natural regeneration transects and two subsidence transects. Fauna surveys included 11 bird census plots and opportunistic documentation of fauna during all other survey methods. This methodology is consistent with 2015 except that the flora quadrat method has been upgraded to Biometrics. This methodology measures vegetation structure and habitat characteristics, thereby enhancing the evaluation of condition and effectiveness of management practices.

A Total of 179 flora species were observed during surveys, comprising 144 native species and 35 exotic species. One threatened species, Eucalyptus cannonii (Cannon’s Stringybark) was detected during surveys

Native species richness decline was limited to one plot (i.e. FL07). Plots FL03, FL05, FL06, FL09 and FL11 had considerable (>15) increases in net change between 2015 and 2016. The remaining plots were more closely related in native species richness based on net change. The 2016 species richness results are trending much more closely to the WBM targets (i.e. FL03, FL05, FL06, FL09, FL11 and FL12).

Comparative analysis of 2015 and 2016 weed species richness showed consistent results although the general trend was increased weed species richness.

The data indicated that Eucalypt canopy recruitment has increased since 2015. Site observations indicate a range of age classes (i.e. small seedling through to larger saplings) that supports the increased regeneration.

No obvious changes were evident along the subsidence transects. Dieback and epicormics regrowth have been observed however other confounding factors (e.g. aspect and associated differences in incident solar radiation) may be the reason for the variation in subsidence monitoring transects.

A total of 42 bird species, five mammals and two reptiles were recorded during fauna surveys. Of these, one species, the Gang-gang Cockatoo (Callocephalon fimbriatum) was observed on multiple occasions within and outside the CHMAs. This species is listed as vulnerable under the NSW Threatened Species Conservation Act 1995 (TSC Act). One pest species, the Feral Pig (Sus scrofa) was also observed during surveys.

10. COMMUNITY

Charbon Colliery held two (2) Community Consultative Committee (CCC) Meetings during the reporting period; 21 March and 17 October 2016. The focus of the CCC meetings was to outline the mine closure procedure and commencement of rehabilitation planning. A copy of the minutes to these meetings can be found on the Centennial Coal website: http://www.centennialcoal.com.au/Operations/OperationsList/Charbon.aspx.

Further to this, Charbon has been and continues to work with the local community in minimizing the social and economic impacts relating to mine closure. Charbon Colliery has made the following community contributions over the reporting period including:

• Kandos Events’ - Donation of shipping container;

• ‘Rylstone Pony Club’ – Donation of steel pipes;

• ‘Cullen Bullen Rural Fire Brigade’ – Donation of lockers;

• ‘Kandos/Rylstone Touch Football Club’ – Sponsorship of a team;

• Rylstone Club Annual Charity Day’ – Cash Donation.

• Negotiations with the Kandos museum to host community/tourism tours of the 2Trunk High Wall

Further to this Charbon has been, and continues to work with the local community in minimizing the social and economic impacts relating to mine closure. Centennial Coal’s community sponsorship for this region has shifted to a strategic capacity building approach, where alternate employment opportunities are being pursued. In partnership with the Kandos Museum and the Lithgow State Mine Railway, Charbon has supported the initiative for train based tourism between Lithgow and Kandos. Train based tourism in this area has been so successful that the rail line to Rylstone has now been opened.

Charbon Colliery received two complaints during the 2016 reporting period, one relating to a water discharge and one other relating to weed control, which are detailed Table 39 and Table 40 below. This is a decrease on three (3) community complaints from the previous 2015 reporting period.

The flora and fauna complaint was received via email from the Department of Trade and Investment, Division of Resources and Energy (DRE) – Orange office, advising that a community complaint had been made to the DRE on 18 January 2016. The complaint was made by a neighboring landholder and reported that Charbon was inadequately controlling weeds on-site. Charbon responded to this complaint and continued to implement its extensive annual weed management program.

The water complaint was made on 2 November 2016 by a resident regarding a drainage line being installed on-site, and the diversion of water from his property. The site contacted the resident again the same day, with consultation ongoing.

Action Site

High stem density and adequate diversity of

species within this older rehabilitation area was

observed. Approximately 80% to 100% canopy

cover was present due to a high density of trees.

Self-thinning is expected to start in the next 5

years due to some Acacia species nearing the

end of their expected lifespan and Eucalyptus

species becoming dominant.

Very few weeds observed.

Minimal erosion concerns are present at this

monitoring location as the soil surface contains

grasses, pasture and leaf litter. In addition,

remnants of deep ripping and rough surfaces

were observed, which slows water flow and

encourages infiltration.

Continue to monitor tree and

understorey success and the presence

of weeds. Also monitor and repair any

various ages.

General Action

Required

Varied success of pasture and tree species was

observed at this monitoring location.

Supplemental tubestock planting was noted in

the pasture area.

This monitoring location contained a moderately

high density of weed species which should be

monitored and managed once the trees are high

enough to be easily identifiable.

Historical erosion issues with contour bank

failure was discussed as well as the option of

re-building the bank to spill to the southern area

away from the current sedimentation dam.

Good stands of established trees were noted

with some Acacia species dying due to age. This

tree establishment forms a strong basis for a

diverse rehabilitation. Natural colonisation from

mature trees in adjacent forest were noted.

Some areas require earthworks and revegetation

following the cessation of mining activities.

Tree emergence should be monitored

and if deemed necessary should be

supplemented with tubestock to obtain

desired species mix.

It is recommended that the Proponent

wait a year or two to allow trees to

emerge and become obvious before a

weed spraying program is implemented

at this monitoring location. Some

noxious weed species may be targeted

if outbreaks become detrimental to the

area.

Erosion along banks or in drainage lines

should be monitored and repaired. Re-

shaping the landform as areas become

available should continue to achieve

gentle slopes (Less than 10 degrees) as

the final landform.

It is recommended that trials continue to

identify best surface ameliorants and

subsoil use on rehabilitation areas.

Rehabilitation less

than 12 months old

General Action

Required

This area has recently been shaped, ripped and

aerial seeded. Some trees have already

germinated (mainly Acacia species), however

they are difficult to identify given the high density

of weed species.

The presence of forest timber and debris

provided erosion control and habitat for various

small animals as noted by the presence of scats.

Any attempt to spray weeds at this stage would

prove detrimental to emerging trees and

pastures.

Various surface ameliorants were noted with

higher pasture success recorded in areas that

contained a high density of organic matter

material such as mulch, as these areas had a

higher water holding capacity.

Diversion banks within this monitoring location

require monitoring for sediment build up and to

ensure that they are working, to ensure that

repairs are made in a timely manner.

De-silting of sediment dams will also be required

to ensure capacity is available and to reduce

sealing of the base of the dams.

Tree emergence should be monitored

and if deemed necessary,

supplemented with tubestock, or re-

seeding to obtain desired species mix.

It is recommended that weed species

are monitored and managed to ensure

that trees are not put at risk of spray

drift.

should be monitored and if necessary,

repaired.

General Action

Required

Monitoring location 5 consists of dumped

overburden material, steep slopes and a

concentrated drainage line which flows into a

site-managed sedimentation dam and then off-

site.

This area requires specific design measures to

ensure a stable surface is achieved. The

addition of organic matter, soil ameliorants, etc.

may be required to ensure successful

germination of pasture species to minimise

erosion and sedimentation risks.

Diversion drains are required to reduce run-on

water. Steep slopes are evident in the natural

surroundings adjacent this site and extra effort

and care is required to stabilise these slopes

whilst rehabilitation is established.

Surface water diversion structures

should be designed to reduce potential

run on volumes.

The landform should be designed to

reduce the risks of surface erosion

12. WASTE MANAGEMENT AND MINIMISATION

In accordance with Schedule 3 C 46d waste management and minimisation practices shall be included in the annual review.

Charbon is in “Care and Maintenance” phase and no longer produces or processes coal at the site. Consequently, all waste produced at Charbon during 2016 is related to the rehabilitation and maintenance of the site. A summary of waste produced on site is detailed in Table 43.

12.1. Sewage Treatment and Disposal

Sewage and other waste water from the bathhouse and site offices within the surface facilities area is treated using an approved biocycle treatment facility. Treated water is used to irrigate landscaped areas and areas undergoing rehabilitation within the Colliery via LDP001 (which allows for the discharge of effluent from the onsite sewage treatment system via irrigation) and is covered under EPL 528. The treatment facilities are serviced by a licensed contractor, as required.

12.2. Oil and Grease Containment and Disposal

There is only one operational diesel storage facility at Charbon which is located in the decommissioned washery area. This facility comprises of one above ground tank and is compliant with Australian Standard AS1940-2004 – The Storage and Handling of Flammable and Combustible Liquids. Bulk diesel is delivered by a suitably licenced fuel delivery contractor as required. All hydrocarbons are stored in a fully bunded area designed to contain 110% of the maximum storage volume.

Unused oil and grease is removed from site by the servicing contractor, which occurs when machinery is serviced, generally on an annual basis.

12.3. General Waste Disposal

General waste is collected into industrial waste containers that are serviced by a licensed contractor. Scrap metal is collected in a separate bin and recycled. Paper and cardboard are segregated on site and recycled by a waste contractor.

13. INCIDENTS AND NON-COMPLIANCES DURING THE REPORTING PERIOD

Table 44 Incident/Non-Compliance Summary

Nature of the incident/non-compliance

High volume air sampler (HVAS) power outage – No sample recorded.

Date of incident/ non-compliance (if known; if not known state not known)

21-26 September 2016.

The location of the incident/ non-compliance (include a figure if appropriate), if known

Charbon’s HVAS unit.

Detail the cause of the incident/non-compliance

Due to a power outage relating to the HVAS unit, it did not record a sample for a six (6) day period, with the source of the power outage appearing to be from a kangaroo colliding with the power cable to the HVAS and dislodging it from the output socket.

Detail action that has been, or will be, taken to mitigate any adverse effects of the incident/ non-compliance

Reported to the Department of Planning and Environment (DP&E) and the Environment Protection Authority (EPA) on 4 October 2016. Charbon does not currently have any active mining operations occurring onsite, therefore dust generation during the period of the power outage is considered negligible. In addition, no exceedances of air quality criteria have occurred during the reporting period or during 2016.

Detail action that has been, or will be, taken to prevent recurrence of the incident/ non-compliance

The power cable was connected back to the output socket and the problem has now been rectified.
