1 Introduction
This Environmental Construction Method Statement (ECMS) documents the requirements for works
associated with the pre-construction, construction and post construction considerations of concrete
batching plants. This document:
addresses the requirements of the Ministers Condition of Approval 30 for the Hunter Expressway
project,
reflects the requirements of the Hunter Expressway Alliance (HEA) environmental management
system (as detailed in the Construction Framework Environmental Management Plan),
incorporates the management measures from the relevant sub-plans and DPI, Fisheries and
RMS guidance documents and
describes the environmental management measures relating specifically to the construction
activities and potential environmental issues.This ECMS has been prepared as a practical environmental management tool for use by all HEA
personnel and subcontractors and incorporates the assessment of the environmental and community
risks for these works. The specific environmental and community management controls developed
and detailed in the ECMS, include the following key information:
Key site and management personnel - responsibilities and contact details.
Operating hours.
Construction details activities, staging and schedule.
Objectives and targets monitoring requirements, criteria and procedures.
Action tables/plans inspection and test plans with actions, responsibilities, training, timing,
reporting, monitoring/auditing and checklists.
Site Drawings - Site layout, monitoring locations, erosion controls, noise barriers, discharge
points and limits of clearing.
1.1 ECMS overview
The General Construction ECMS 1 will be required for allconstruction sites.
This activity specific ECMS provides only specific requirements for concrete production and delivery.
When constructing and operating concrete batching plants, this ECMS will need to be used in
conjunction with ECMS 1: General Construction which will apply for the non-specific requirements for
the site.
The Site Supervisor in consultation with the QA Manager will determine which ECMSs are required for
each work site. Refer to the overview map contained in ECMS #1 for an overview of all ECMSs.
1.2 ECMS attachments
The ECMS site-specific Environmental Control Plans (ECPs) include site-specific drawings on a
cadastral and air photo base with site boundary overlain, general traffic controls and site-specific
environmental management action tables. ECPs are to be read/ implemented in conjunction with the
ECMS document and relevant reference documents and are for day-to-day reference for managingactivities on the individual sites. The ECPs have been designed as A3 and/or A1 drawings for
attachment to site shed walls.

Attachment E Environmental best practice for concrete washout.
Attachment B contains the erosion and sediment control measures and drainage for the two concrete
batching plants near the Project Office and the east bound rest area respectably. Each concrete
batching plant will require a first flush system flow system as indicated in Attachment C to ensure
wastewater is diverted, captured, treated and reused to prevent release to local waterways. The
specific control measures for the operation of a concrete batching plant are provided in Attachment D.
1.3 Key reference documents to ECMS
The development of this ECMS has been guided by detailed management plans and reports to
develop appropriate mitigation measures for managing the environment impacts associated with
batching plants. The relevant CEMP sub-plans listed in Table 1.1 and the specific references relevant
to batching plants as listed in Table 1.2, will be referred to as needed for specific information for day-
to-day worksite activities.

2 Scope of works
This ECMS covers the establishment and operation concrete batching plants for concrete productionand delivery as required for the construction of the 13 km expressway project from the Newcastle Link
Road interchange with the F3, through to Buchanan.
2.1 Overview of activities
A concrete batching plant is required for the supply of concrete during the construction program. The
main concrete batching plant is located at approximate chainage 6800 adjacent to the site office.
A second concrete batching plant is required for pavement construction as part of finishing works. It
will be located in the east bound rest area at alignment chainage 7400:8000.
The main concrete batching plant has been established within an existing 1.2h cleared area on a siteleased from a privately owned rural property used for cattle grazing and poultry. The batching plant
site was a former quarry that has been highly disturbed as a result of previous excavations. The site
is disused by the landowner and is surrounded by a large patch of remnant vegetation which
separates it from the construction compound.
The location for the paving batch plant is on disturbed land used previously by the Alliance to assist in
construction of the Expressway. Locating the batch plant on land adjoining the Expressway formation
will minimise the need to use main arterial routes and reduce interaction with public road users for the
production and placement of necessary concrete material to complete the Hunter Expressway.
Note: the grout batching plant is covered under the Mine Void Drilling and Grouting ECMS #6 (HEA-
CMS-GL-ENV-006-00-01).
2.2 Concrete production and delivery
The main concrete batching plant will be near the Project Office in Buchanan as identified in
Attachment A. A consistency assessment was prepared for this site which included an assessment
against MCoA 129 and additional environmental assessment.
The paving concrete batching plant will be located in the east bound rest area as identified in

2.4 Batching plant facilities
The main and paving batching plants will be approximately 1.2 and 1 hectares in area respectively and
will accommodate the following facilities:
A concrete batching plant.
A 400 kw generator.
A concrete silo.
Five 15 metre by 15 metre aggregate bins.
Two storage containers for additives.
On-site parking for approximately 30 vehicles.
Sediment pond.
The soil and concrete testing lab and the curing shed will be located at the Project Office site.
2.5 Batch plant accessAccess to the main batching plant will be from:
1. George Booth Drive to the south via a new construction access road around the perimeter of
remnant vegetation.
2. Existing unsealed accesses track which leads to the Project Office and HEA road corridor to

2.6 Batching plant process
A wet mix mixer plant will be installed consisting of aggregate bins with associated weigh hoppers,
conveyors, cement silos, a mixer, and an office (batch hut). Up to five aggregate stockpiles will be
established on the ground in proximity to the plant. Each stockpile will cover an area of approximately
15 metres by 15 metres. Aggregates will be stockpiled to a height of approximately 3 metres.
The plant would also include two storage containers, each 6 m x 3 m for concrete additives, including
air entraining agent and water reducing agent.
Two water tanks will be located in proximity to the batch plant. A slump testing area, a small storage
and laydown (hardstand) and an ablution facility will be at the site. The site will store a self-bunded

twin skin tank for the storage of diesel and a self-bunded tank for the storage of various oils. The
workshop, soil and testing lab will be located at the Project Office site.
On-site parking will be provided for approximately 30 vehicles in the vicinity of the workshop. The
batch plant and workshop will be floodlit at night for security reasons. A 1.8 metre high fence will also
be erected around the perimeter for security purposes. A septic effluent disposal system will be
installed to manage domestic wastewater generated on site.
2.7 Concrete waste solids reuse
Concrete waste solids will be removed routinely from the settlement pits and reused, primarily for
roadbase and fill during construction and finishing works. Where concrete solids cannot be reused,
excess concrete will be allowed to settle and then disposed of at a licensed waste facility that accepts,
General Waste (non-putrescibles).
There will be no disposal of concrete wastewater to sewer, soil, waterways or drains. Agitator trucks
transporting concrete will be washed out at the concrete batching plant, unless the distance from theconcrete batching plant would lead to the impairment of operation of the agitator truck. Where site
washout is required of concrete laden equipment, vehicles or machinery, a geotextile lined ditch will be
constructed in accordance with the Best Practice Guideline for Concreting Contractors, DECCW, Nov
2004 (refer Attachment E for an extract of the guideline).
2.8 Water capture, use and reuse
Water saving measures will include:
Use of a high pressure, low volume nozzle for wash down operations in the truck wash bay.
Siphoning off water capture in the sediment basin for washdown operations.
2.9 Hours of operation
Normal construction hours apply to the activities included in this ECMS. These hours are:
Monday to Friday 7:00 am 6:00 pm
Saturdays: 8:00 am 1:00 pm
Sundays & Public Holidays no work
The batching plants will be required for the duration of the Stage 2 construction works which is
expected to be for approximately 2.5 years.
Out of hours work may be required for a number of project components such as pre-cast beams and
large bridge pours. As per the EPL:32965, out of hours work can be undertaken for dust suppression.
With the storage and handling of raw materials for concrete production it is likely that dust suppression
will be required in high wind conditions at the batching plant. Out of hours work, shall be carried out in
accordance with the Project EPL (section 3.2), and the Noise and Vibration Management Plan.
2.10 Site rehabilitation and restoration
), The condition of the batching plant sites is currently highly disturbed as a result of previous
earthworks. Therefore, the final rehabilitation strategy for the batching plant sites will be negotiated
with the land owners. Where possible, the rehabilitation strategy adopted for the sites will seek toimprove on the current condition of the area; however, this will depend on the land owners plans for
this parcel of land.

Notes on First Flush System:
1. All dirty water around the batch plants is directed into the
Settling System. This Settling system acts as a first flush
system as well.
2. The first flush system works by capturing the dirty water
runoff for a 10mm rainfall event (5,600 litres). However, this
system has the capability to capture a 55mm rainfall event
(31,000 litres) assuming the wedge pit valve is closed and the
pit is full and both containers are full but not overflowing. If
the wedge pit is not full then the first flush capacity is
increased. .
3. After the system if "full", the water banks up the inlet
channels to the point that it starts to overflow at the bypass
point.
4. All clean water falling on the site is diverted around settling
tanks and into the Batch Plant Dam.5. The second settling tank has an additional capacity of

Document Number: HEA-RP-GL-ENV-012-00-0Page 1
INTRODUCTION
The Protection of the Environment Operations Act
1997 (POEO Act) sets out requirements for protecting
the environment from pollution. The HEA and its
contractors therefore have a legal obligation to ensure
adequate management of concrete operations and
prevent contaminated materials entering waterways.
Thiess currently hold Environmental Protection
Licences for the operation of concrete batching plants.
These licences shall be available to site staff and kept
at the batch plant premises (as well as on the HEA
document management system).
The following summary information is applicable to
HEA batch plant sites:
SURFACE WATER MANAGEMENT
1. Clean water diversion (bunds or drains) shall
be installed to prevent off site water coming
onto the batch plant site.
2. A First Flush (rainfall capture) System shall be
installed - Refer to First Flush for Batch PlantLayout Sheet(to be displayed at each of the
HEA batch plants)
Figure 1: Surface water being directed into the WRS.
3. A three bay Water Retention System (WRS)
shall be provided to catch and control water
run-off from the batch plant area. The water
shall be reused for batching by pumping out
of the most downstream holding tank and
back into the batch plant water supply tank.
This shall be undertaken after overnight
settling has occurred.
4. Capacity to capture (at least) a 10mm rainfall
event shall be maintained at all times. Prior to
predicted, large rainfall events (e.g. greater
than 30mm), additional capacity in the WRSshould be provided via increased dewatering
to the batching water tank.
Figure 2: Value which allows the water level to
be reduced in the wedge pit.
5. At no time shall water from the WRS be
pumped offsite.

WASTE CONCRETE MANAGEMENT
1. Concrete waste excavated from the wedge pit
shall be positioned for drying immediately
next to the wedge pit. Once dry it can be
transferred to an appropriate storage location
(refer to First Flush for Batch Plant Layout
Sheet), prior to disposal or re-incorporation
into road construction materials.
2. All agitators loaded at the batch plant shall
washout directly into the wedge pit.
BASIN MANAGEMENT
1. After a rainfall event, all end of line sediment
basins/dams are to be restored to their
required capacity within 5 days (see water
level marker install at each basin). This should
be undertaken via using the water for
batching operations, and to fill water carts in
the first instance. If the capacity can not be
restored via these methods within 3 days,
treatment, testing and releasing of the water
will be necessary.
Contact Environment Staff prior to releasing water
offsite from batching plants.
DUST MANAGEMENT
1. During paving operations, the risk of tracking
cement and mud onto public roads is
increased. Measures to reduce mud tracking
include:
a. the installation of rumble grids or
hardstand areas at batch plant exits
points
b. regular monitoring and clean up via a
street sweeper or water-cart broom
2. Stockpiles shall be kept damp to prevent winderosion and associated dust issues.
Figure 3: Water sprinkler systems assist in reducing
dust issues
