Construction Surface Water Management Plan
2.45 All stockpiled construction materials shall be stabilised and covered where practicable to prevent
erosion or dispersal of the materials. The Proponent shall manage any fill/ preload material brought to the
Site in manner that prevents erosion and dispersal of those materials.
The above conditions are addressed where relevant in this CSWMP.
Construction of Stage 1 of the Project commenced in January 2008, with operations of the Stage 1 Project
components commencing in the third quarter of 2010. These works allow the CET to operate up to the initial
Project capacity of 30 Mtpa. The Stage 1 Project components included the construction of:
•
rail infrastructure including one train unloading station;
•
the southern portion of the coal storage area including two combined stacker/reclaimers; and
•
wharf facilities including one shiploader and two shipping berths.
The Stage 2AA construction activities are scheduled to commence in the third quarter of 2010. The construction
period is expected to take approximately 29 months and, when complete, will increase the capacity of the CET to
53 Mtpa. The Stage 2AA Project components will include the construction of (Figure 2):
•
a second train unloading station and associated rail infrastructure;
•
a portion of the coal storage area including a third combined stacker/reclaimer; and
•
a second shiploader.
The High Capacity Optional Inlet Rail Spur is not required for Stage 2AA of the Project.
The environmental management described in this document is specifically designed to ensure the construction
activity outlined for Stage 2AA is undertaken in a manner compliant with the requirements of the Project Approval
(06_0009).
NSW Maritime was granted Development Consent (DA 134-3-2003-i) (the Port Consent) by the Minister on
9 August 2005. The Extension of Shipping Channels, Port of Newcastle includes dredging, excavation, treatment
and disposal of sediments from the south arm of the Hunter River.
The dredging required for the development of the Project up to the initial 30 Mtpa capacity (Stage 1) involved the
removal and handling of material including sand, silt clay and rock from the south arm of the Hunter River. There
will be no dredging or marine works conducted during Stage 2AA of the Project and as such the Port Consent
(DA 134-3-2003-i) does not apply to the Stage 2AA development phase. Therefore, this CSWMP has been
prepared to only provide for the management of surface water and stormwater on the Project site.
This CSWMP has been prepared to assist NCIG in the implementation of appropriate environmental
management measures during the Stage 2AA construction period of the Project. Where there is any conflict
between the provisions of this CSWMP and any Contractors’ obligations under their respective Contracts,
including the various statutory requirements (i.e. licences, permits, Project Approval conditions and relevant
laws), the Contract and statutory requirements are to take precedence. In the case of any real or perceived
ambiguity between elements of this CSWMP and the above statutory requirements the Contractor shall first gain
clarification from NCIG prior to implementing that element of this CSWMP over which the ambiguity is identified.
The remainder of this CSWMP is structured as follows:
Section 2:
Summarises the potential surface water quality impacts for each area of the Project site.
Section 3:
Provides the surface water and stormwater management measures and the Erosion and
Sediment Control Plan.
Section 4:
Provides details of the surface water and stormwater monitoring program.
Section 5:
Describes the reporting requirements for this CSWMP.
Section 6:
Lists the references cited in this CSWMP.

SURFACE WATER AND STORMWATER MANAGEMENT
This section provides details on the objectives, concepts and design criteria which are used in the design of the
infrastructure.
The construction surface water management strategy for the Project is based on:
•
the separation of surface water runoff generated from within the active Project construction areas from that
generated from surrounding areas; and
•
the implementation of adequate water management controls to minimise the potential for impacts to off-site
water resources such as adjacent wetland areas, adjacent ponds and the Hunter River (Figure 3).
3.1
THE INTERNAL DRAINAGE NETWORK
Temporary erosion and sediment controls (e.g. silt fences and construction settling ponds) will be installed prior
to the commencement of construction activities on the Project site.
A network of water management structures will be used to manage runoff on and around the construction site.
All long-term site water management structures have been lined with low permeability materials (e.g. compacted
clay or geo-membrane) to minimise the potential for leakage. Water management structures have been
designed and constructed with sufficient capacity for a 1 in 100 year average recurrence interval (ARI) rainfall
event. Project water management structures will also be designed to operate in accordance with Environment
Protection Licence (EPL) 12693 obtained from the Department of Environment and Climate Change (DECC)
(now the Department of Environment, Climate Change and Water).
In accordance with Condition 2.41, Schedule 2 of Project Approval (06_0009), Project water management
structures will be designed to operate to comply with Section 120 of the Protection of the Environment
Operations Act, 1997.
Where relevant, details of the site drainage layout for the Stage 2AA construction period are shown on Figure 4.
The provisional site drainage layout for the final operating capacity of 66 Mtpa is shown on Figure 5. Detailed
plans of the Stage 2AA and provisional final site drainage layout are provided as Attachment 1.
3.1.1
Coal Storage Area
The site drainage network has been established to capture site runoff, including runoff transferred from the rail
infrastructure corridor and the wharf facilities area (Figure 4).
The Project coal storage area is relatively flat with a slight fall to the north-west (Figure 4). Three coal stockpiles
pads and two berms were constructed in the southern section of the coal storage area during Stage 1 of the
Project. A sub-grade drainage system has been incorporated into the coal stockpile pads to capture water
infiltrating through the coal stockpiles. The sub-grade drainage system comprises of a series of underground
drains to control drainage from the coal storage area (see Attachment 1 for details of the sub-grade drainage
system).
Stormwater runoff collected on the Project infrastructure areas is diverted through sediment control structures
and/or construction settlement ponds. Construction settling ponds have been installed where necessary at the
end of the open drains to act as sediment and pollutant traps (Figure 4).

Construction Surface Water Management Plan
Two construction open drains running east-west will divert run-off from the northern portion of the coal storage
area around the coal stockpiles and berms during the Stage 2AA construction period (Figure 4). One drains to a
construction settling pond to the west of the coal storage area and then to the primary settling ponds. A second
construction settling pond located in the east of the coal storage area collects runoff from the second
construction open drain. Runoff from this pond is pumped to the overflow pond. The primary and secondary
settling ponds and overflow pond have been constructed to the north of the coal storage area. The primary and
secondary settling ponds and the overflow pond capture sediments not trapped in the construction settling
ponds.
Consistent with the design goal of no discharge to the Hunter River during operations, the construction settling
ponds, primary and secondary settling ponds and the overflow pond are designed and constructed with sufficient
capacity to contain a 1 in 100 year average recurrence interval (ARI) rainfall event. All Project water
management structures will be operated in accordance with the requirements of the Project Approval and
EPL 12693.
An existing stormwater drainage channel runs from the overflow pond to the Hunter River. This channel was
used to return seawater to the south arm of the Hunter River from reclaimed dredged material during Stage 1 of
the Project. As dredging activities are not to occur during Stage 2AA of the Project, no water will be discharged
to the Hunter River unless expressly provided for under the provision of an EPL.
3.1.2
Rail Infrastructure Area
Surface water features in the vicinity of the rail infrastructure corridor comprise waterbodies created by the
existing Kooragang Island mainline rail embankment, emplacement cells associated with the KIWEF and a
number of depressions in the KIWEF landform that intermittently fill with water in response to rainfall runoff.
There is also a drainage channel adjacent to the Kooragang Island mainline which drains to the south arm of the
Hunter River. Deep Pond is a large waterbody in this area and is connected to a series of ponds to its south-east
via drainage lines (Figure 4) (NCIG and Connell-Hatch, 2006). Figure 4 shows the various catchments within the
rail infrastructure corridor.
Stormwater runoff from areas adjacent to the Project rail infrastructure corridor is diverted via table drains along
parallel the Project rail infrastructure corridor and in to the existing drainage system across the KIWEF. The rail
embankment includes culverts where it traverses low points in the existing topography to allow drainage across
its alignment and prevent ponding in adjacent areas. Details of the drains and culverts along the rail
infrastructure corridor are shown on Figure 6 and Figure 7. These drains and culverts were constructed as a part
of the Stage 1 works.
Runoff from the train unloading stations will be collected in sumps before being transferred via pump and pipeline
networks to the coal storage area drainage system (Figure 4 and Attachment 1). These works were constructed
as a part of the Stage 1 project and are currently operational.
The High Capacity Inlet Rail Spur (Figure 2) will not be constructed as a part of the Stage 2AA construction
activities. This will result in any potential impact on Deep Pond being minimal.
3.1.3
Wharf Facilities and Shiploader Area
The wharf facilities and shiploader area is relatively flat with a slight fall to the south-east (Figure 4). The wharf
facilities have been designed to ensure that all stormwater from this area drains away from the Hunter River.
Stormwater runoff from the wharf facilities and shiploader area passes through sediment control structures
before being collected in a settling basin. Water collected in the settling basin will be transferred via pump and
pipeline to the coal storage area drainage system (Figure 4).
Silt curtains will be installed adjacent to disturbance areas that may create excessive disturbance during
construction works in the wharf facilities and shiploader area.
