Introduction SSD 7592, for the Springvale Water Treatment Project, was granted to Springvale Coal Pty Limited on the 19
th of June 2017 by the Planning Assessment Commission (under delegation
from the Minister of Planning). Veolia Australia & New Zealand (Veolia) have been engaged as the construction and operations contractor to carry out the Springvale Water Treatment Project (Project) for MP Water, who are contracted to Springvale SK Kores Pty Limited, Centennial Springvale Pty Limited (together, the Springvale Joint Venturers) and EnergyAustralia NSW Pty Ltd (EnergyAustralia) for that purpose. The approved Project encompasses the following major elements:
A mine water transfer system with sufficient hydraulic capacity to allow transfer of 42 ML/day of dewatered mine water from the existing mine water Booster Station 2, forming part of the approved dewatering facilities on the Newnes Plateau, to the Mt Piper Power Station (MPPS) site;
A new water treatment plant at MPPS incorporating desalination processes to reduce the salinity in mine water to a standard suitable for either industrial reuse or environmental release;
Transfer of treated water from the water treatment plant for use in the MPPS cooling water system;
Infrastructure to allow pumping of excess treated water to Thompsons Creek Reservoir;
Disposal of residuals from the pre-treatment process in the reject emplacement area (REA) at the Springvale Coal Services site;
Transfer of the saline brine stream to the MPPS for integration with existing fly ash and brine disposal practices; and
Installing a crystalliser to provide further treatment of the additional salt load generated within the MPPS cooling water blowdown system.
The NSW Department of Planning and Environment (DPE) issued a modification application (SSD 7592 MOD1) for the Project on 12 January 2018. The changes to the Project as a result of the modification include an amended brine management process, a change to the pond strategy, additional hydraulic controls and minor changes to the pipeline alignments and an increase in the estimated peak construction workforce.
On the 16th of April 2018, DPE approved a request to extend the construction hours for the
Water Treatment Project. The approval was in relation to:
Extended construction hours for the Water Transfer System works over a 48hour period to complete horizontal directional drilling at the Wolgan Road drill site.
Extended construction hours (24hours, 7 days a week) at the Water Treamtnet Facility as required, to ensure the Project is completed within the approved timeframe (June 2019).
In accordance with Schedule 4, Condition 7 of SSD 7592 (as modified), reproduced below in Table 1, this progress report has been prepared to address the requirements of this condition.
The reporting period covers the period between the 20th of June 2018 to 19
th of September
2018 (Reporting Period).

1.1
1.2
(c) identify any potential delays and describe measures to ensure that the Water Treatment Plant is operational by 1 July 2019; and
1.3
(d) be made publicly available on the Applicant’s website; 2.1
to the satisfaction of the Secretary. Noted
1 Project Status
1.1 Works Completed during Reporting Period
During the Reporting Period the progress made is as follows:
Design:
The detailed design is nearing completion allowing other delayed contingent work
components to be progressed;
Model review and design workshops are mostly complete with all relevant outcomes
defined and being incorporated into the completed models; and
Veolia has reached 91% completion in the detailed design, for issue to construction
subcontractor, Abergeldie, for supply and installation.
Water Treatment Facility (WTF):
Detailed excavation to pile caps complete;
Concrete works are ongoing with completion planned for September 2018;
Underground services pits and conduits completion planned for September 2018;
Process drainage installation is commenced and progressing to completion;
Installation of a fire main complete;
Deliveries of equipment for the WTF are progressing; and
Installation of the equipment for the WTF is ongoing with interconnections to
commence.
Water Transfer System (WTS):
Pipe deliveries complete;
Vegetation clearing and grubbing of the pipe corridor in Zones from 0 to 4 and 6
complete;

7
Vegetation clearing and grubbing of the pipe corridor in Zone 5 has commenced and
is progressing;
Erosion and sediment controls are progressively being installed along the pipeline
construction corridor. The erosion and sediment controls regularly monitored and
maintained for them to work properly, and effectively minimise sediment pollution;
Directional boring of pipeline under Castlereagh Highway and Coxs River complete.
The pipe has been pulled back through the final borehole to complete installation of
the WTS section in Zone 3;and
Installation of the pipeline for WTS sections in Zone 2 and Zone 6 are complete.
Procurement:
Procurement packages cumulatively ordered at 80% complete.
1.2 Works Proposed for Upcoming Year
The following work is scheduled to be completed in the forward 12 month period:
Engineering and Procurement
Completion of remaining final detail design; and
Placement of any outstanding orders for equipment and materials.
Water Transfer System (WTS)
Installation of the WTS sections in Zones 0,1,4,5;
Joining and hydrotesting of all of the WTS sections;
Installation of fibre optic communication cable for pipeline monitoring;
Rehabilitation of the disturbed areas; and
Pre-commissioning and commissioning of the WTS.
Water Treatment Facility (WTF)
The remaining electrical design;
The final remaining detail design;
Interconnecting pipelines to the power station water systems;
Receipt of all process equipment and installation;
Installation of switchboards and power supplies;
Piping and cabling installation and connections;
Installation of buildings, offices and associated infrastructure; and
Pre-commissioning and commissioning of the WTF.
1.3 Identified Potential Delays and Mitigation Measures
Recent reviews of the project schedule have highlighted actual and potential slippages
against contracted construction completion dates. This has been driven by refinements to the
WTF configuration, which has effected completion of detailed design activities and
construction requirements more broadly. To mitigate the delay risk Veolia has engaged
external specialist assistance within project delivery to enhance and increase the capability of
its team to successfully deliver the works. Initial reviews have highlighted the opportunity to
bring forward completion of underground services and completion of all civil works to provide
a clear access to maximise productive installation of the Mechanical and Electrical packages.
Additionally, the construction sequencing is being modified to maximise the approved benefit
available through increased construction and commissioning hours (shift-work and 7-day
operation). Agreements are in place between Veolia and its major contractor which have
streamlined communications and workflow, enabling critical fabrication and pipe-spooling
works to be fast-tracked from newly available design information.

The project forward schedule is being reviewed to incorporate a range of strategies to allow
increased work-fronts and parallel activities than originally anticipated due to the design
complexity and procurement delays. The impact of these strategies will be confirmed within
the next quarterly report as all Design and Procurement activities are finalised.
