Springvale has completed the following actions in relation to noise management:

• Toolbox Talk issued to dozer operators.
• Dozers inspected by Westrac technicians.
• Guard on dozer, thought to be exacerbating noise levels, removed.

Springvale Stand-down Survey

Springvale Stand-down Survey

• The suspension of operations at Springvale mine for 8 weeks

provided a rare opportunity to assess the impact of the stand down

• n employees, their families and the local-level impacts of the

mine’s absence from the local economy.

• A series of focus groups were conducted in August 2016 to assist

develop the survey instrument and a survey was conducted with Springvale employees in December 2016.

• Employee participation (staff and workforce) was 71%.

Springvale Stand-down Survey: Research Outputs

The output of the research is valuable for reasons including but not limited to:

• provide an understanding as to how this stand down impacted on people;
• support both the economic impact assessment (EIA) and social impact

assessment (SIA) elements of future consent applications for the Western

• perations;
• understand the local social and economic impacts of employment in an area

such as Lithgow, rather than applying state and national level metrics in the assessment;

• consider the sustainability of Centennial’s workforce and employment profile
• f the Lithgow region into the future;
• future planning for the Lithgow LGA and surrounding region;
• the impact of the existing approvals pathway; and
• understand the immediate impact in relation to the transition away from

mining on regional communities such as Lithgow.

Springvale Stand-down Survey: Employee responses

Employee response to stand down:

• The responses clearly demonstrate the negative effects the stand-

down had on individuals and their experiences in the workplace. During the stand-down – managing the effects:

• There were significant pressures placed on employees in both

workplace and domestic environments. These effects were also felt by family and/or other household members.

• The data on type of leave taken and the effects this has had on

plans for subsequent leave provide one measure of the ongoing effects of this event.

Springvale Stand-down Survey Employee responses

Returning to work:

• Despite the relief of getting back to work, the experience has clearly

caused the workforce to consider the longer-term ramifications of the stand-down, the circumstances that precipitated it and their own future in the industry.

• 89 percent reported that they were considering their future in the

industry. Future of mining / future of Lithgow

• The results indicate a significant degree of both pragmatism and

concern over the future of the coal mining industry.

• The prospects of finding alternative employment in the region were

clearly considered as poor by respondents.

• 47 percent of respondents who recognised that they would, or may

have to, leave the region to find alternative work if necessary.

Springvale Stand-down Survey: Employees are Stakeholders

• 77 percent of employees reside within a 15 kilometre radius of

Springvale Mine. All employees reside within 67 kilometres.

• 48 percent of households are situated in the immediate Lithgow

township.

• The 263 respondent’s households comprise a total of 849 residents

meaning there is an average household size of 3.3 persons.

• Tenure in the area (years in residence) is on average, 31 years.
• 93 percent of respondents either fully own or are buying their

present homes.

• 62 percent of the workforce reported being involved with local

community, service, cultural and sports organisations.

• Approximately 72 percent of take home pay is spent in the local

area.

Centennial Coal Community Consultative Committee Meeting August 9th 2017

Introduction and Agenda

45

Presenter

• David Randall
• Projects Manager
• Centennial Coal

Agenda

• Springvale Water Treatment Project
• Regis Water Transfer System

Springvale / Energy Australia Water Treatment Project

• Key objective
• Improve environmental outcomes for the receiving waters in the Coxs River

catchment

• Will achieve objective by:
• Meeting the 2019 mine water quality criterion (500 µS/cm at 90th percentile) in

Springvale Mine’s consent SSD 5594 (Schedule 4 Condition 12)

• Discontinuing discharges of LDP009 mine water or any treated mine water to

the environment

• Maximising the reuse of treated mine water within the Mount Piper Power

Station (MPPS) cooling water system

• Reducing the reliance on extraction of water from Coxs River catchment (Lake

Lyell) and other sources (Fish River Scheme) to meet the power station make- up water requirements.

• Project operational by 30 June 2019

46

Project Components

• Pipeline Transfer System
• Raw water transfer system from Gravity Tank compound on Newnes Plateau to a

water treatment plant (WTP) at MPPS

• Treated water pipelines from the WTP to MPPS cooling water system and Thompsons

Creek Reservoir

• Network of pipelines from the WTP to brine management system at MPPS
• Residuals transfer pipeline from the WTP to REA at Springvale Coal Services Site
• Water Treatment System
• New pre-treatment clarifier and new desalination facilities (RO) for treatment of all

mine water

• Integration with existing MPPS water treatment system plus a new crystalliser for brine

management

• By-product Management
• Residuals (pre-clarification process) to be emplaced in the new REA at SCSS
• Brine (reverse osmosis / blowdown processes) to be managed within the existing

MPPS bine management system

Water Usage at MPPS and Mine Inflows

• Water usage within the cooling water system at MPPS depends on

energy demand:

• Average of 40 ML/day
• 54 ML/day for full capacity operations
• <30 ML/day when MPPS operating at or <50% capacity.
• Groundwater modelling (CSIRO 2016) for Springvale and Angus Place

mines shows an average peak mine inflow of 36 ML/day.

• Proposal to transfer 42 ML/day to the Project to provide sufficient

redundancy is incorporated into the project to ensure reliable treatment

• f all mine water transferred from Angus Place and Springvale to

MPPS.

• Treated water will be used as priority for cooling make-up water prior to

extracting water from Lake Lyell and Fish River.

• Excess treated mine water will be temporarily stored in the Thompsons

Creek Reservoir for subsequent reuse at MPPS, no discharge of treated water.

50

Project Key Benefits

• Will achieve better water quality performance measures in the Coxs River catchment than

required in the Springvale Mine’s consent SSD 5594 given nil discharge development

• Provides an opportunity for beneficial industrial reuse of mine water at MPPS
• Minimal environmental footprint
• Project’s socio-economic profile:

–

The Project allows continued operation of Springvale Mine:

–

will provide a reliable supply of coal to MPPS

–

critical to ensuring secure and reliable electricity supply to NSW 15% - 20%

–

Estimated Capex in excess of $100 Million

–

Creation ~ 25 FTE operational workforce

–

Supports the ongoing viability of existing MPPS and Centennial (Springvale, Angus Place, Western Coal Services) operations and continued employment of >660 FTE personnel. 51

• The McPhillamys Project must secure a reliable source of

process water for the project to be approved.

• 13ML/D of process water is required.
• The water is used to process ore and produce gold at the

mine.

• An opportunity exists for Springvale and Energy Australia to

transfer 13ML/D of process water to the McPillamys Project

• This water would come from the following 3 sources

1. Mount Piper Power Station (MPPS) – Blow Down Ponds 2. Springvale Coal Services - LDP006 3. Angus Place – LDP001
