Air, Noise & Vibration Management

E1 Speed limit within the site boundary including access tracks restricted to a maximum of 40kph.

Construction

E2 Activities will be managed onsite to ensure dust is not a hazard. Observational monitoring of dust will be undertaken along the construction right of way (ROW) where adjacent to sensitive receptors, including monitoring of fine particulates.Management/control measures proportionate to the level of risk must be put in place to minimise risk of generation. Control measures used may include:• Water carts used on unsealed work areas; • crushed rock placed on existing permanent unsealed

access tracks where agreed with relevant stakeholders • Water spray units used on soil stockpiles and during the

loaded and unloaded of dust generating materials .i.e. soil/sand/fill and aggregates; and

• Vehicle loads covered when carrying dust (or litter) generating material.

Dust suppression activities are to be undertaken as directed by the APA Construction Manager, who will take

the following factors into consideration:• Weather patterns; hot, dry, windy forecasts; • Ground cover .i.e. exposed surfaces;• Type and moisture content of soil present; and• Type of activities being conducted, such as vehicle

movement, vegetation clearing and excavation.

E3 If all available methods of dust stabilisation fail to suppress dust and dust emissions are evident beyond the Site boundary, the APA Construction Manager will temporarily modify or suspend dust generating activities until conditions subside.

Construction

E4 Vehicles, plant and machinery will be maintained in good working order to minimise air emissions that may cause nuisance and so that noise and vibration do not exceed the manufacturer’s specifications.

Construction

E5 Construction may occur up to 24 hours a day, 7 days a week. Normal working hours will be between 7 am and 6 pm weekdays and 7 am to 1 pm Saturday. Where, for practical reasons, out-of-hours work is unavoidable, it must only occur with prior approval by the APA Construction Supervisor and affected residents must be notified at least 24 hours before the out of hours work commences.

Construction

E6 Managing noise from construction activitiesConstruction noise and vibration will be managed with reference to Section 2 (Construction and Demolition Site Noise) of EPA Publication 1254 Noise Control Guidelines and Section 5 (Noise and vibration) of EPA Publication 480 Environmental Guidelines for Major Construction Sites. This includes the development of a construction noise and vibration management plan (CNVMP) plan to manage noise and vibration during construction in consultation with the EPA , and approved by the relevant authority . The plan will include: • critical works through townships or other sensitive

regions affected by the pipeline works including Hastings;

• site specific noise controls to be implemented at the HDD locations listed in Performance D9; and

• an appropriate stakeholder communication strategy that incorporates the complaint management procedures and includes prior communication advice and notices to affected residents, with assessment

conducted prior to any night works taking place , and timely communication of noise monitoring results, on request, to affected residents .

The plan CNVMP w ill also include the following general good practice techniques: Using the lowest-noise work practices and equipment

that meet the requirements of the job. Locating and positioning site buildings, access roads

and plant to minimise noise disturbance at the locality. Installing broadband reversing alarms on construction

vehicles and machinery in preference to 'beeper' reversing alarms. The site will also be planned to minimise the need for reversing of vehicles.

Turning off plant and vehicles when not being used. Taking care not to drop spoil and construction

materials that cause peak noise events.The CNVMP must be informed by modelling and/or monitoring undertaken by a suitably qualified noise and vibration consultant prior to the construction activities occurring.Where the construction noise and/or vibration levels are predicted or measured to be exceeded at sensitive receptor locations, noise management measures detailed in the CNVMP and consistent with the requirements of NSW CNVG shall be implemented prior to works occurringreduction measures proportionate to the level of risk of impacting on a sensitive receptor will be included in the planning and design of the Project activities. These may include, but are not limited to, the following: Adopting engineering noise controls at the source (e.g.

silencer, mufflers, enclosures) by the best practical means using current technology – Expected reduction of 10 dB to 15 dB.

Installation of onsite barriers such as hoardings or temporary enclosures to provide a noise barrier between any particularly noisy construction works and the residences - Expected reduction of 5 dB to 10 dB.

Limiting normal works between 6am and 7am to the arrival of staff on site, toolbox meetings and pre-work checks. The use of loud equipment, generation of unnecessary noise and the movement of vehicles on the construction footprint will be minimised outside normal working hours.

Jim Antonopoulos, 19/11/20,

We either need to define what an extended period is or delete this


Normal trigger for any management action should also be audibility. Recommend a threshold trigger of B/g+0dB (which triggers works notifications / communications). Further management measures triggered at B/g+different margins as per NSW CNVG. Only having 55 dBA as the single trigger point of any engagement/management is concerning if that is what is intended here. The 55 dBA level is when relocation is normally adopted. It is easier to adopt the NSW guidance fully which addresses this, otherwise we can customise a version with all the management measures at different noise levels. Is that preferred?


inaudibility is the EPA target requirement. B/g +5dB is not likely to meet inaudibility. B/g+0dB or more (ie B/g-5dB) would be a more appropriate screening level for inaudibility. There cant be any audible construction works at night unless it qualifies as unavoidable.



with impacted landholders to discuss individual mitigation options.Options include:-Provision of ear plugs or noise cancelling

Noise will be predicted or measured above 55 dB(A) for two or more nights to justify the application of management measures.

Residents with special requirements will be consulted with on a case to case basis.

E8 Out of hours work will be scheduled in consideration of other projects occurring in the area to reduce cumulative noise impactsThe EPA and the proponents of the projects listed below will be consulted during detailed design and the construction planning phase for the purpose of managing cumulative noise impacts associated with the following projects:

• Pakenham East rail depot construction and operation (Department of Transport)

• Healesville-Koo Wee Rup Road upgrade construction (Major Road Projects Victoria and the principal contractor)

• Crib Point Jetty upgrade construction works (Port of Hastings Development Authority)

• Crib Point Jetty operation (United Petroleum).

B10 Swamp Skink

Where areas of Swamp Skink habitat are identified in the Environmental Line List (Attachment G), the following measures will be taken to reduce impacts:

Clear and grade activities will occur preferentially in warmer months (late Spring to early Autumn) when skinks are more active and better able to avoid activities.

A fauna handler will complete an inspection of the habitat area immediately prior to any vegetation removal (including ground cover).

If clear and grade occurs during cooler months, when skinks may be in burrows (April to September or as determined by a fauna ecologist), a fauna handler will be present during topsoil stripping to monitor the area and inspect stripped material.

A fauna handler will complete an inspection of topsoil and vegetation stockpiles prior to respreading.

Erosion and sediment controls and temporary fencing will be inspected for sheltering skinks prior to removal.

Any individuals captured during the inspections described above will be relocated to the nearest adjacent habitat away from the construction area.

Construction

B11 Southern Brown BandicootFollowing clearing, fencing suitable to exclude the Southern Brown Bandicoot will be installed at the edges of the construction footprint where it is adjacent to any of the of Southern Brown Bandicoot habitat areas identified in the Environmental Line List (attachment G) to reduce the likelihood of animals entering the construction footprint. Monitoring of fencing will be undertaken and repairs completed as required.

In the event that Southern Brown Bandicoot are discovered within the construction footprint, all mobile construction equipment in the surrounding area will cease work, excluding use of light vehicles to move staff to and from the area. Mobile construction equipment will not recommence work until a wildlife handler has removed the individual or it has been confirmed that individual has left the workspace. Captured individuals will be removed and relocated to nearest adjacent habitat away from the construction area.

If night time activities are required within or adjacent to any of the identified locations of Southern Brown Bandicoot habitat, a wildlife handler will be available to the construction site.

At least one t T emporary Southern Brown Bandicoot shelter site s (shelter pile or bandicoot hide) will be established for every 100 metres of potential habitat along the alignment to provide interim cover / refuge whilst vegetation is re-established.

If an area of Cinnamon Fungus Phytophthora cinnamomi dieback is identified within the ROW, biosecurity clean-down locations will be established at the exits to the area. The design of any clean-down locations will consider the containment and appropriate disposal of removed soil and runoff. Clean-down will be required for vehicles, machinery and personnel clothing exiting the area. This will involve the following steps: scrape off soil (clumps, lumps and thick caked

on soil), manure and organic material from vehicles, machinery and personnel clothing with a shovel and/or hard bristled brush.

Spray/rinse with Phytoclean vehicles and machinery areas and footwear or other items areas that have contacted soil.

These locations and requirements will be communicated to all personnel.

Updated to reflect B Lane Reply evidence and M Cole evidence

M Cole evidence:

A survey every 200m along the proposed pipeline would be necessary to determine the active contamination sites. Plant and equipment could not move between these sites without washdown. Plant and equipment could not move across farm boundaries between infected and non-infected farms without washdown. Washdown between properties is essential.

Bunded washdown pads are concreted with containment drains and facilities to sanitise the collected water and soil. Adequate testing of the soil and water before it is released from the site for safe disposal. Risk is reduced for grassland but is high for vegetation, so testing is adjusted accordingly.

If considering the models for information on presence or absence of the pathogen, then they need to be used pragmatically. If the pipeline is following an existing easement then risk is lower. If in vegetation then risk is high. The pipeline should be tested along its length for the presence of Pc. Pc is in the agricultural land so cleaning from property to property is essential. If in a crown land easement then risk is lower.

Accepted in part as above. Concrete wash down bays not accepted

relevant discharge criteria will be disposed to an EPA Victoria licensed facility.

Dewatering of excavated trenches/bellholes will be managed to minimise sedimentation, including the use of sediment control devices to remove suspended solids and dissipate flow as described in EPA publication 480 (Section 4.4 Dewatering work sites) and EPA publication 275 (Section 16 Water treatment). Sediment control devices may include, but are not limited to:

i. settlement pondsii. floating pump intakesiii. filtered intakes/outlets

Discharge will be to low gradient, stable, grassed areas and through ESC systems to prevent scour or erosion.

Discharge to land will not occur within 50 metres of watercourses.

Water will not be discharged directly to waterways or into stormwater drains without prior approval from relevant authorities.

Visual monitoring will be undertaken during discharge to land.

Where groundwater is entering excavations, dewatering activities will be limited to two days or less in trenched sections and HDD tie-in bell holes, and 10 days or less at thrust bore sections and thrust bore bell holes.

T6 Trench breakers will be installed adjacent to watercourses, wetlands and steep slopes as shown in the standard drawing (CPT.2373-DWG-L-0106).

T12 Contaminated groundwater/trench water Contaminated groundwater/trench water will

be managed in accordance with:– SEPP (Waters)– PFAS National Environmental

Management Plan. All Project personnel will be made aware of

the presence of contaminated groundwater containing PFAS east of the former Tyabb landfill (Environmental Line List - Attachment G).

Where there are open excavations adjacent to the former Tyabb landfill site, the excavation will be monitored for landfill gas as part of morning pre-start checks and prior to any hot works commencing.

Disturbance of saturated soil and groundwater within the PFAS affected area will be minimised. The management plan will include measures to prevent migration of PFAS into the surrounding soil or surface water.

An intrusive groundwater investigation will be undertaken in the area between KP7.3 and KP7.9 prior to commencing pipeline construction, to confirm presence or absence of contaminated groundwater within the area, due to historical and existing land uses.

Water from areas that have been identified as contaminated will not be discharged to the environment (land, waterways, sewer).

Contaminated water will either be treated onsite, depending on contaminant encountered (this may require approval from the EPA Victoria) or disposed offsite to an EPA Victoria licensed facility. Alternatively, a construction approach may be adopted where contaminated groundwater is left in-situ (i.e. not abstracted or disturbed).

Where the potential for soil or groundwater contamination has been identified, any imported backfill materials must have similar or lower hydraulic conductivity to the surrounding soils.

the watercourse has been undertaken. The exposed trench within the watercourse and riparian

zones will be reinstated immediately following the installation of the pipeline.

Waterway reinstatement will be designed to avoid future erosion over the pipeline alignment. This may include the use of riprap made of stones to stabilise the waterway.

Temporary ESC will be provided as needed to prevent erosion and scour until the vegetation has established.

Visual monitoring will be undertaken downstream of the trench during flow events if the trench has not been reinstated.

Temporary diversions will be provided if there is permanent or tidal flow in the waterway in accordance with International Erosion Control Association (IECA) Best Practice Erosion and Sediment Control Appendix P: Land-based Pipeline Construction (2008). Flow diversion measures may include pumps to ensure that water can be moved from one side of trench to the other, screened inlets (or other appropriate equipment) to minimise the entrapment of aquatic fauna and outlet structures that are designed to avoid scouring of the channel.
