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
on 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
operations;
• 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
of 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.
Care in Centennial: Respecting our Stakeholders

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
47
Project Area Boundary

Water Treatment Plant – Indicative Layout
49
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 of 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.
