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 Minister’s 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 all construction 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 managing

activities on the individual sites. The ECPs have been designed as A3 and/or A1 drawings for

attachment to site shed walls.




This ECMS includes the following:

� Attachment A – Environmental Control Plan.

� Attachment B – Progressive Erosion and Sediment Control Plan – main batch plant site.

� Attachment C – Batching plant first flush system.

� Attachment D – Environmental Update 12 – Concrete Batch Plant Sites.

� 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 production

and 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 site

leased 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

Attachment A. A consistency assessment was prepared for this site which included an assessment

against MCoA 129.




2.3 Key elements of the batching plants

• Access road will be at max. 10m wide and will be spray sealed.




Activity Description


• Widening of existing ramp onto the main alignment

Batching plant operational activities • Truck and agitator washdown

• Dewatering

• Recycling waste concrete

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 access

Access 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

the north.

A description of access road widening and measures to minimise impacts from road access and the

historic cutting of the Richmond Vale railway corridor is covered in ECMS 3 Site Construction

Compound, section 2.4 and in Attachment A.

The paving batching plant will accessed from the main alignment through an existing access track.

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 the

concrete 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 to

improve on the current condition of the area; however, this will depend on the land owner’s plans for

this parcel of land.

Notes All dirty water around the batch plant is directed into the Settling System. This Settling system acts as a first flush system as well (Wedge Pit). The first flush system works by capturing the dirty water runoff for a 10mm rainfall event (3500litres). If the wedge pit overtops water is directed into a overflow cut diversion drain that flows into the sediment pond. All site water from the storage area will be directed into the sediment pond. As the batch plant area is situated in a cut, clean water is directed around the site via a large diversion bund All shown basins will be sized as per Blue Book for inclusion on the Environmental Protection License. All controls will be installed and maintained as per the Blue Book.

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.

INTRODUCTION

The Protection of the Environment Operations Act1997 (POEO Act) sets out requirements for protectingthe environment from pollution. The HEA and itscontractors therefore have a legal obligation to ensureadequate management of concrete operations andprevent contaminated materials entering waterways.

Thiess currently hold Environmental ProtectionLicences for the operation of concrete batching plants.These licences shall be available to site staff and keptat the batch plant premises (as well as on the HEAdocument management system).

The following summary information is applicable toHEA batch plant sites:

SURFACE WATER MANAGEMENT

1. Clean water diversion (bunds or drains) shallbe installed to prevent off site water comingonto the batch plant site.

2. A First Flush (rainfall capture) System shall beinstalled - Refer to First Flush for Batch PlantLayout Sheet (to be displayed at each of theHEA 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 waterrun-off from the batch plant area. The watershall be reused for batching by pumping outof the most downstream holding tank andback into the batch plant water supply tank.This shall be undertaken after overnightsettling has occurred.

4. Capacity to capture (at least) a 10mm rainfallevent shall be maintained at all times. Prior topredicted, large rainfall events (e.g. greaterthan 30mm), additional capacity in the WRSshould be provided via increased dewateringto the batching water tank.

Figure 2: Value which allows the water level tobe reduced in the wedge pit.

5. At no time shall water from the WRS bepumped offsite.

WASTE CONCRETE MANAGEMENT

1. Concrete waste excavated from the wedge pitshall be positioned for drying immediatelynext to the wedge pit. Once dry it can betransferred to an appropriate storage location(refer to First Flush for Batch Plant LayoutSheet), prior to disposal or re-incorporationinto road construction materials.

2. All agitators loaded at the batch plant shallwashout directly into the wedge pit.

BASIN MANAGEMENT

1. After a rainfall event, all end of line sedimentbasins/dams are to be restored to theirrequired capacity within 5 days (see waterlevel marker install at each basin). This shouldbe undertaken via using the water forbatching operations, and to fill water carts inthe first instance. If the capacity can not berestored via these methods within 3 days,treatment, testing and releasing of the waterwill be necessary.

Contact Environment Staff prior to releasing wateroffsite from batching plants.

DUST MANAGEMENT

1. During paving operations, the risk of trackingcement and mud onto public roads isincreased. Measures to reduce mud trackinginclude:a. the installation of rumble grids or

hardstand areas at batch plant exitspoints

b. regular monitoring and clean up via astreet sweeper or water-cart broom

2. Stockpiles shall be kept damp to prevent winderosion and associated dust issues.
