1 IntroductionThis Environmental Construction Method Statement (ECMS) documents the requirements for worksassociated with widening and upgrading of existing access tracks to the construction corridor. Thisdocument:

addresses the requirements of the Minister’s Conditions of Approval 30 for the Hunter Expresswayproject,

reflects the requirements of the Hunter Expressway Alliance (HEA) environmental managementsystem (as detailed in the Construction Framework Environmental Management Plan),

incorporates the management measures from the relevant CEMP sub-plans and

describes the environmental management measures relating specifically to the constructionactivities and potential environmental issues.

This ECMS has been prepared as a practical environmental management tool for use by all HEApersonnel and subcontractors and incorporates the assessment of the environmental and communityrisks for these works. The specific environmental and community management controls developedand 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, and monitoring/auditing and checklists.

Site Drawings - Site layout, monitoring locations, erosion controls, noise barriers, discharge pointsand limits of clearing.

A number of access routes will be required into the Hunter Expressway Project alignment throughoutconstruction. It is anticipated that there will be at least four (4) stages of development executed on thecurrent access avenues into the alignment:

1. Immediate enabling works to the existing access tracks without vegetation removal for pre-construction geotechnical and mine void investigation drill rigs and support vehicles and lightconstruction vehicles,

2. Immediate enabling works to the existing access tracks with conditional vegetation removal forvehicles as per above;

3. Track widening to eight (8) meters, to achieve haul road status; and4. Constructions of new link roads as the alignment clearing works proceed.


1.1 ECMS attachmentsThe General Construction ECMS 1 will be required for all construction sites.

This activity specific ECMS provides only specific requirements for access tracks. When undertakingaccess track work, this ECMS will need to be used in conjunction with ECMS 1: General Constructionwhich 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 foreach work sites. Refer to the overview map contained in Attachment B of ECMS 1 for an overview ofall ECMSs. Specific environmental constraints are further identified in the maps contained inAttachment A.

Attachment A – ECMS Environmental Control Plans

Attachment B – Construction Access Roads General Arrangement; provides sketches of accesstrack locations and classification (ie: use as is, upgrade without widening, upgrade and widen to8 m, construct new link road)

The ECMS site-specific Environmental Control Plans (ECPs) include site-specific drawings on acadastral and air photo base with site boundary overlain, general traffic controls and site-specificenvironmental management action tables. ECPs are to be read/ implemented in conjunction with theECMS document and relevant reference documents and are a day-to-day reference for managingactivities on the individual sites. The ECPs have been designed as A1 drawings for attachment to siteshed walls. This ECMS includes the following ECPs:

Flora and Fauna Management Hours of Operation Noise and Vibration Soil and Surface Water Management Construction Air Quality Management.

1.2 Key reference documents to ECMSThe following detailed management plans and reports have been prepared in conjunction with theECMS to assist in the mitigation of specific environmental issues for the works. This ECMS providesthe required detail for day-to-day worksite activities and the management plans and reports will bereferred as needed for specific information requirements:

2 Scope of worksThis ECMS covers works associated with:

Repairs to existing access tracks that do not require any widening or vegetation removal

Upgrading existing access tracks to haul road status, including widening and associatedvegetation removal,

Construction of new access tracks to provide linkages for complete circuits

This ECMS covers all access tracks required for the project. Construction methodology is providedbelow. The Construction Activities Table (Table 2.1) provides a summary of construction activities tobe undertaken on the worksites, indicative timing, equipment/plant and an indication of key issuesrelated to the activities.

2.1 Pre-construction activities

2.1.1 Survey and fencing off sensitive environment

An Aboriginal Archaeological Survey and Flora and Fauna Survey will be conducted alongaccess tracks where tracks are located outside the extent of the previous surveys. Allidentified issues will be managed in accordance with the Indigenous Cultural HeritageManagement Sub Plan (HEA-PL-GL-IHP-001) and Flora and Fauna Management Sub Plan(HEA-PL-GL-FFP-001). Any sensitive areas identified in the reports will be fenced prior totrack upgrading.

Areas identified as having threatened species in the vicinity of track upgrade works will beinspected by a qualified ecologist who will locate and mark (with tape or similar) thethreatened flora. Any marked flora will be fenced and signs erected prior to any works beingundertaken so that trimming or clearing of threatened flora is prevented. The location ofthreatened flora will be clearly communicated to relevant work teams via the GroundDisturbance Permit (GDP) system.

2.1.2 Site inductions

All HEA personnel/contractors associated with the access track works will be inducted to thesite. The induction will include relevant information on all environmental and communityissues.

2.1.3 Community notification

Relevant community groups that utilise the Sugarloaf Ranges track network for recreationalactivities will be informed of the commencement of construction and changes to access in thevicinity of the works. Signage will be placed at intersections of access tracks advising ofconstruction before works commence.

2.2 Staging of works

2.2.1 Existing tracks upgraded without widening

Tracks identified in the Construction Access Tracks General Arrangement (Attachment B) as‘existing tracks, upgrade without widening’ will not be widened beyond their current boundary,which will be defined by the growth of any vegetation at the edge of any track. There will be no


vegetation clearing to repair these tracks, however in some instances minor trimming ofoverhanging branches may be required.

1. Immediate enabling works without vegetation removal

Tracks will be inspected by the Project Engineer and/or Project Foreman for suitability for use.Tracks which have erosion features and rutting that prevent safe passing will have all or someof the following improvement works:

Removal of high points Infill of scours using aggregates and road base; Blade leveling of sections of tracks featuring rutting; Removal/leveling of redundant stockpiles impeding access; Compaction of the surface by track rolling.

Suitable erosion and sediment controls will be developed and submitted to the EnvironmentManager (EM) and approved for use prior to works commencing. Once implemented, theEnvironmental Officer (EO) will inspect the work for suitability.

Once works are complete and tracks are subject to construction traffic, they will be monitoredfor erosion on an ongoing basis by the construction environmental officer and/or the foreman.

2. Immediate enabling works with conditional vegetation removal

Where vehicular movements are impeded by overhanging limbs, some vegetation may requireremoval; however this will be restricted to trimming only and will not result in significantdamage to trees.

In areas identified as containing both EEC and non-EEC, and thus included within theconstruction clearing limit, only branches of trees that measure less than 75mm will beremoved. Under no circumstances will individual trees be removed, as per the EnvironmentalWork Method Statement – Surveying.

2.2.2 Track widening to achieve haul road status

A survey pick-up of all tracks in the vicinity of the project alignment will be executed. Surveydata will be analysed to determine those tracks that will be upgraded to allow the safe haulingof materials throughout the project alignment. In all cases, a minimal disturbance footprintapproach will be adopted.

Surveyed track widths will allow the calculation of accurate clearing areas required to widenspecific routes.

Prior to any widening works commencing, routes will be reviewed and approved by theConstruction Manager or his delegate.

Upon approval, the following sequence of events shall occur:

1. Develop and approve An Inspection and Test Plan (ITP) for the “Construction of HaulRoads”. The GDP shall be opened and process of sign off by relevant managers,including Safety, Utilities and Environment commenced.

2. Where threatened flora and EEC have been identified in the vicinity of track works, anecologist shall locate and mark (red & white hazard tape) the location prior to any worksbeing undertaken to prevent accidental trimming or clearing of threatened flora. Thelocation of threatened flora and EEC shall be clearly communicated to the work team viaGDPs.


3. Survey team to peg the clearing limits of the haul road at ten (10) meter centers inaccordance with Flora and Fauna Management Sub-Plan Measure 29 – Section 5.2.3.1.

4. Survey team to individually mark the trees on the clearing limit5. Environmental officer and Site Engineer to verify the individually marked trees “limit

vegetation” on the limits of the haul road clearing6. Stocking tracks (tracks that will be ultimately closed) to be identified and clearly marked

on a plan for storage of mulch and unsuitable material7. Hold points on the ITP for the commencement of clearing to be released8. Clear and grub works commence9. Placement of suitable material to commence10. Final survey as constructed pick-up to be completed.

Refer to ECMS #2: Clearing and Topsoil Management.

Cleared vegetation will be recovered and/or mulched for future reuse or recycling as perMCoA64.

2.2.3 Construction of new link roads

As the alignment clearing works proceed, there may be an opportunity to construct moreefficient haul roads by constructing link roads to complete haul road circuits. In this instance,the sequence of events will be as per 2.2.2.

Particular attention must be paid to ensure no effects on the over-all project clearing limit areincurred.

2.3 Construction activitiesTable 2.1 provides a summary of the proposed construction activities to be undertaken on theworksite, indicative timing, equipment and plant, and an indication of key issues related to theactivities.

Note: Add 5 dB(A) to the measured construction noise level for tonal or impulsive construction activity.

Construction Traffic Noise: Less than 60 dB(A) LAeq,1hr during working hours; 55 dB(A) LAeq,1hr outside of working hours Not to increase existing noise at any receiver > 2 dB(A).


Provide site personnel with induction/instruction on key noise issues andmitigation measures, approved construction hours and community concerns.

PEM

Install signage is installed on site to inform workers of approved hours for noisyactivities.

PEM


Noise and Vibration Management

Investigate and report all noise or vibration complaints in accordance with theHEA Community Engagement Strategy.

PEM/CRM

Switch off plant and equipment when not in use. All

Schedule activities to minimise co-incidence of noisy plant working simultaneouslywhere practicable.

SE

Ensure noisy plant items are not located in the vicinity of sensitive receivers(where practicable).

SE

Ensure that where practicable, rock excavation is conducted by means of rippingrather than rock breaking.

SE

Where delivery of oversize items of plant/ equipment to the worksite outside ofstandard work hours is required, this must be in accordance with RTArequirements and approval of EMR/DECCW.

CM

Check that heavy vehicle movements related to worksite activities are inaccordance with the traffic management plan and do not pass through residentialareas.

CM

Fit all plant and equipment with properly functioning noise attenuation devices (egmufflers). Test all plant and equipment on delivery to site to ensure it complieswith noise and vibration output as described in the Noise and VibrationManagement sub-plan.

CM/PEM

Construction Air Quality Management

Sub Plan ref: Construction Air Quality Management Plan (HEA-PL-GL-AQP-001-001-00-02)

Objective: To minimise dust generation and manage emissions from construction activities to preventimpacts on surrounding receivers.Performance Criteria:

Depositional dust goals of max 4 g/m2 per month, subject to monthly background levels,as per DECCW guidelines.

No complaints received from nearby residents or local road users.

Monitoring sites/sensitive receivers:Location 1: F3 Freeway, North-bound on-Ramp, Seahampton, located at the southern end of works(100m -500m)Location 2: John Renshaw Drive, Buchanan, near the southern end of works. (70km SW of nearestresidence)


Pre-construction

Consult with local residents before works begin (i.e. site clearing and major earthworksnearby) and notify of the nature and timing of the work.

CRM

Dust suppression activities

Regularly control dust emissions using water sprays on water carts over unsealedtrafficable areas, earthworks and stockpiles, and other surfaces as necessary. Ensurecarts are available and maintained at all times.

SS, SE,CM

Water can only be extracted for dust management or other construction related activities CM


Construction Air Quality Managementfrom sources approved by the Environment Manager. For example, sediment basins,local creeks where allowed. All water movements are to be covered by a watermovement permit1.

Clean any dirt tracked onto public roadways from construction vehicles using brooms ora street sweeper. SS, SE

Suspend work if excessive dust generation from surface dirt accumulation occurs untildust emissions are controlled.

SE,CM,PEM

Enclose storage / weigh bin tops to minimise wind-generated dust emissions. SS

Ensure no open burning or incineration on site unless otherwise approved by the EPA. SS

Minimise clearing at any one time by leaving vegetation within work sites and within thecorridor unless clearing is absolutely necessary. Commence revegetation of clearedareas as soon as practicable to prevent or minimise wind blown dust.

SS, SE

Vehicle, plant and equipment

Cover loads and secure tailgates from construction vehicles prior to leaving worksite toprevent loss of load on public roads and areas accessible to the public. Any spillage isrequired to be removed within 24 hours.

SS

Restrict and monitor construction traffic using local unsealed roads to 40 km/h. Installsignage. Control access to all construction areas to specific entry/exit points and confinevehicle movements to designated construction areas.

SS, SE

Provide facilities, such as rumble grids at site exit points to minimise tracking mud, dirtor other material onto a public road or footpath. Ensure wheels and undercarriage oftrucks are clean prior to the exiting the worksite. (See the flora and fauna section formore detail on these measures).

SE, CM

Service construction plant, vehicles and equipment regularly and maintain in topcondition so that existing exhaust emissions standards are met or surpassed.

SS, SE

In the event of visible smoke emissions from equipment lasting longer than 10 secondsduration, have equipment taken out of service and adequately repaired or tuned so thatsmoke is no longer visible for periods exceeding 10 seconds.

SS

Ensure plant or equipment is not left idling for longer than 15 minutes. SS

Stockpiling

Revegetate temporary stockpiles to stabilise the soil and minimise wind erosion. SS, SE

Establish quick growth cover crops to protect long-term topsoil stockpiles and clearedareas as soon as possible after completion. (See soil and water section for more detailon stockpiling).

SS, SE

Extreme conditions

On high wind days, either reprogram construction activities work that could cause anuisance or danger to people or property, or relocate to areas removed from sensitivereceptors.

SE, CM

No spark generating activities (such as welding) on days with a Total Fire Ban. CM

Avoid use of lime for stabilisation activities during windy days. SS, SE

Instigate a call out system to respond to dust suppression requirements out of hours andon weekends.

CM

1 The water movement permit system is an onsite system designed to track and check use of water across thesite.


Construction Air Quality Management

Monitoring

Monitor dust deposition monthly throughout construction to determine effectiveness ofdust suppression measures. Review and modify dust control and operational proceduresif dust deposition levels are exceeded.

PEM

Monitor and record weather conditions, including rainfall, wind speed, wind direction andhumidity on a 24 hour basis.

CM

On high wind days where on site controls cannot prevent transport of dust, make arecord of: date, time, location, wind, direction, wind speed, pre-existing dust controls,additional controls implemented; and modifications to work implemented.

CM

Monitor and record any complaints received in relation to air quality. CRM, PEM

Visually monitor dust during daily inspections during pre-construction and constructionphase.

SE, PEM

Undertake periodic visual checks of exhaust systems from construction plant, vehiclesand machinery. PEM
