1 INTRODUCTION

1.1 Purpose

This Spoil Management Sub Plan (SMP) forms part of the Construction Environmental Management Plan (CEMP) for the Hunter Expressway Alliance (HEA).

The purpose of the SMP is to:

• identify the environmental management issues associated with the sourcing, handling,

transportation, stockpiling, disposal and reuse of spoil material; and

• document and describe the systems and procedures developed to mitigate

environmental impacts.

This Sub Plan provides practical measures that will be put in place in order to minimise any detrimental impact on the surrounding environment resulting from spoil management during pre-construction, construction and post-construction phases of the project.

This Sub Plan is applicable to all HEA activities during the construction phase of the Project

While this Sub Plan provides overall guidance and direction for the management of spoil, Work Method Statements (WMS) and Environmental Construction Method Statements (ECMS) will be prepared to be used in site specific situations.

1.2 Objectives

The objectives of the Spoil Management Sub Plan are to:

• manage spoil generated during the Hunter Expressway Alliance Project in accordance

with preferred waste management hierarchy of avoidance, minimisation, reuse,

recycling and finally disposal;

• where possible ensure all clean and/or treated spoil shall be reused or recycled;

• Minimise off-site disposal of spoil;

• minimise the impact of erosion and sedimentation from construction activities

associated with the Project;

• ensure all sediment and erosion controls are implemented on site in accordance with

best practice environmental management as outlined in Managing Urban Stormwater -

Soils and Construction (Landcom 2004) including Volume 2D Main Roads Construction;

• provide an organised, integrated and systematic approach to effectively address spoil

management issues during the project; and

• provide staff with an increased level of understanding and awareness of spoil and fill

management issues.

disposal requirements, record keeping and licence requirements.

Applies to the handling and disposal of spoil associated with excavation works on

this project.




Contaminated Land

Management Act 1997

This Act regulates the discovery and management of contaminated land.

S60 of this Act requires that: notification be provided to DECCW if:

� Contamination exceeds guideline level on land

� Contamination enters or may enter neighbouring land and exceeds guideline level

� Contamination otherwise meets criteria in regulations




3 SPOIL MANAGEMENT OVERVIEW

3.1 Spoil types

Spoil is defined as any earthen material that is surplus to requirements or unsuitable for re-use in fill and embankments (such as unsuitable rock and soil material) or material that is contaminated.

This plan has been prepared to facilitate the beneficial reuse of all material, ensuring that none is disposed off-site, except if unsuitable for reuse.

Fill is defined as earthen material excavated from one location along the corridor (for example, for a detention basin or cut excavations) and relocated elsewhere as compacted fill.

Cut and fill material will generally not be stockpiled, but will be removed from the excavation site and transported directly to the construction face for immediate reuse as compacted fill. Unsuitable excavated material will primarily be transported to identified locations within the road corridor for reuse or, if space is not available, will be stored temporarily off-site for re-use later.

Select material is defined as earthen material of comparatively higher quality, necessary for

engineered backfill and incorporation in upper earthworks layers as part of the overall

pavement design. Typically on the HEA project this will include high strength sandstone and

low/medium strength claystones, siltstones and sandstones.

Wherever possible, select material will be sourced on site, and stockpiled as necessary until

incorporated in the works. However, preliminary investigations suggest that a considerable

proportion of the select material required for the project will need to be sourced from off site.

Unsuitable (non-contaminated) material on the HEA project is generally composed of silty, sandy, gravely and organic clays; sandy silts; clayey, silty and gravely sands and carbonaceous rock.

This material will be reused on the project in the following ways:

• widen embankments where possible;

• land contouring;

• landscaping mounds;

• landscape treatments; and

• noise mounds (if required).

Topsoil will be stripped and recovered for reuse in landscaping and revegetation. On

average, the top 100mm of topsoil will be collected for future use.




3.2 Spoil strategy

The following provides an overview of the HEA strategy for achieving the key spoil management objectives:

• Minimise the amount of spoil generated – this requirement will be achieved by

ensuring that the design minimises the volume of spoil generated from excavation (a

key driver for this is the need to minimise our construction footprint in order to reduce

clearing). It should be noted that the minimisation of spoil generation is a standard

process in developing designs and planning construction activities as there are

significant financial savings in minimising spoil generation and management. .

• Classify the spoil generated using recognised guidelines and its geotechnical

characteristics – The Waste Classification Guidelines (DECCW Apr 08) are the

primary guidelines for the classification of spoil and other waste materials in relation to

contamination. The geotechnical characteristics of spoil are also important to consider

as it will determine the potential engineering uses of spoil.

• Maximise the beneficial reuse of spoil on site based on its classification (both

contamination category and geotechnical characteristics) – Some of the spoil

generated is expected to be able to be reused on site and will be suitable as general fill

across the site. Some spoil may be unsuitable, however this maybe used for inclusion in

capped landscaping mounds or features. Some spoil material, mainly due to its

geotechnical characteristics will not be suitable for reuse.

• Maximise the beneficial reuse of spoil off site based on its classification (both

contamination category and geotechnical characteristics) – Whilst it is HEA’s

intention to try and re-use all material on-site some of the spoil generated may be able

to be reused off site on other projects. Further investigation into the needs of the

numerous nearby mine sites will continue in this regard. Some spoil material due to its

geotechnical characteristics will not be suitable for reuse.

• Dispose of spoil off site based on its contamination classification - spoil unable to

be reused on site or off site would be disposed of at a facility that has the appropriate

development approval and Environment Protection Licence to receive and store the

relevant waste classification of the spoil.

• Manage the excavation, storage, transport reuse and disposal of spoil to

minimise impacts and meet other environmental requirements – this includes

implementing mitigation measures to manage potential impacts on traffic and soil and

water, dust generation and contamination of spoil (e.g. onsite - dust control, erosion and

sedimentation controls, monitoring and validation for contamination and Potential Acid

Sulphate Soils, offsite – tracking and monitor spoil/fill movements and quality

(contamination), haulage routes, impacts on public safety and roads and public amenity,

noise impacts and required compliance requirements (i.e. approvals and

consents/licences).

Note: The detailed spoil and materials management strategy will be addressed in both the Earthworks Management Plan and the Materials Management Plan for the Project.

3.3 Spoil generating activities

Spoil generated by construction will primarily come from excavation works. The spoil is expected to vary in content with silty, sandy, gravely and organic clays; sandy silts; clayey, silty and gravely sands and carbonaceous rock.




The activities associated with the generation and management of spoil and fill materials are:

• clearing of vegetation;

• selection of material;

• clearing of topsoil;

• excavation of earthen material;

• blasting of earthen material (if required);

• transport of earthen material;

• storage/stockpiling of spoil, topsoil and mulch; and

• reuse of spoil, topsoil and mulch.

There is a small possibility that acid sulfate soils may be encountered during construction work. Management and mitigation measures of potential acid sulfate soils are presented in the Acid Sulfate Soil Management Strategy (Refer to Appendix C of the Soil and Water Management Sub Plan).

3.4 Volumes and sources of spoil

Overall approximately 2,172,994 m³ of material will be won on-site from excavation works over the life of the Project. This will be made up of select material, un-suitable and topsoil.

Approximately 370,918 m³ of material will require importing to site to be used as select material for pavement design, drainage blanket material and as backfill for retaining walls. It should be noted that this figure does not include the aggregate required for the supply of concrete for the batching plant which, based on current estimates, will require 100,000 tonnes of aggregate and 60,000 tonnes of sand. The source location for this material is currently unknown but will likely be sourced from local quarries..

Given the volume of imported material required in excess of that won on-site, numerous local quarries will be engaged to supply the required material. At this stage it is not known which quarries will be used as negotiations are currently taking place.

Refer to Table 3.1 for details on material quantities and Table 3.2 for the location of potential spoil disposal and off-site storage / re-use sites.

As can be seen from Table 3.1, approximately 2,115,833 m³ of material will be used as fill for pavement and embankment construction. Approximately 293,079 m³ of spoil will be produced which may require off-site disposal or re-use.

3.5 Spoil classification

The classification of spoil will be undertaken in accordance with the Waste Classification Guideline, 2008 including the implementation of a spoil sampling and analysis program during excavations. This will determine the type of spoil:

Virgin Excavated Natural Material (VENM): DECCW places no specific restrictions on reuse options of VENM

Clean fill (e.g. Inert): If deemed suitable (i.e. waste classification and poses no environmental or OH&S risk) can be used as fill on site. Topsoils are suitable for reuse in rehabilitation works

Potentially contaminated material: Requires management or disposal in accordance with EPA guidelines




3.6 Locations of spoil disposal and off-site storage / re-use sites

Potential spoil disposal / off-site storage sites are detailed in Table 3.2.

1Negotiations are continuing with Coal & Allied re: the use of the Brick Pit as a disposal site with the

potential for using surplus spoil to rehabilitate the site. 2Both landfill sites are licensed to accept general solid waste (non-putrescible)

Prior to any permanent disposal of spoil at these locations (or others yet to be determined), a review of the CoA, associated approvals and environmental documentation shall be carried out by the HEA Environment Team and additional approvals sought when required.

3.7 Transportation of spoil

40T off-road dump trucks and on-road spoil trucks will be used to move spoil material between sites in the construction corridor. Wherever possible, material is to be moved internally along the construction corridor.

Where the construction programme necessitates movement of material prior to access along the construction corridor becoming available, material will be hauled on public roads by road trucks, in accordance with the project Traffic Management and OHS Management Plans.

Haulage by road trucks will be along the Project corridor wherever possible. In instances where haulage of cut material is required by road, exit from and entry to the project will be via specific Project access points, using designated haul routes as detailed in the project Traffic Management Plan.




3.8 Storage of spoil

Material which can be re-used on-site but which cannot be directly re-placed will be stored in designated stockpile areas on-site. Where space is restricted material may require temporary storage off-site prior to re-use on-site. Temporary spoil storage locations are detailed in Table 3.2.

All spoil material requiring disposal will be classified according to the Waste Classification Guidelines 2008 (DECCW publication)

The Construction Environmental Manager and Project Engineer will identify storage areas prior to commencement of construction in each area primarily to ensure that disturbance to local residents is minimised, local amenity is maintained, and to protect receiving waters from potential runoff.

Temporary stockpile areas for the Project will be located as detailed in Table 6.1.

Erosion and Sediment Control Plans prepared for specific areas will contain details on the locations and control measures for stockpiling. The relevant ECMS will also provide general measures for the location and management of stockpiles.




4 PERFORMANCE CRITERIA

The performance criteria for the Spoil Management Sub Plan are to ensure:

• All clean and/or treated spoil shall be reused or recycled to the greatest extent where

possible and cost effective to do so (CoA 123).

• Spoil generated from construction activities is maximised in preference to any import of

fill (CoA 123).

• Erosion of stockpiles is minimised and release of sediment into any waterway is

avoided;

• Any weed invasion of stockpiled materials is managed;

• Dust generated from stockpiles is minimised;

• Stockpiled material is reused wherever possible rather than disposed of offsite;

• Staff are aware of the requirements of relevant sections of documents to be adhered to

including: the CEMP, any associated Environmental Construction Method Statements

(ECMS), erosion and sediment control plans (ESCP) and all other statutory

requirements to be met whilst on site; and

• Effective communication is maintained with statutory authorities and all statutory

requirements are carried out to control impacts on the environment and prevent

pollution.
