Buildcorp Group Contracting Pty LtdACTIVITY MANAGEMENT MEASURES
Piling works — Water suppression technique to be used
— Gas monitoring as outlined in Section 5.2 of this AQOMP (2021)
— If trigger levels of VOCs and landfill gases are exceeded during piling works,
management measures outlined in section 3.9 of the WSP CEMP (WSP 2021a)
will be implemented.
— During piling works, all spoil materials should be inspected for visual and
olfactory signs of contamination, including:
- hydrocarbon or other odours.
- staining and other visual indicators including dark material.
- oily sheen or the presence of liquid hydrocarbons; and
- large or frequently occurring foreign materials including potential asbestos
containing materials.
Bulk earthworks, filling works, — Stockpiling for longer than 28 days will be minimised. Contaminated materials, if
stockpiling, material movement encountered, which require stockpiling for longer than 28 days will be stabilised
or covered with geotextile fabric
— Known contaminated material must be stockpiled separately and placed on plastic
sheeting to prevent leaching of contaminants into surrounding soils
— Where a stockpile has the potential to generate dust, control measures such as
wetting the stockpile will be implemented during the day
— Geotextile material will be used to cover partially excavated contaminated
stockpiles at the end of each working day
— The height of contaminated stockpiles will be minimised to 2 m, covered
overnight with an appropriate material and removed off-site as soon as practicable
for disposal
— Stockpiles will be managed in accordance with Buildcorp’s Erosion and Sediment
Control Plan (Buildcorp 2021)
— Earthworks and exposed areas to be revegetated to stabilise the surfaces as soon
as practicable
— Where acid sulphate soil is encountered, management measures detailed in
Section 5.2 of the WSP Acid Sulfate Soil Management Plan for CNSW
Development Plan (WSP 2021b) will be implemented
Excavation/stockpiles – odour, — Odour suppressants, such as hydrocarbon mitigation agents, will be applied to
VOCs, SVOCs control odour at the point of excavation or at the stockpiles, if strong hydrocarbon
odour are detected.
— Stockpiles of piling spoil are to be covered.
— A biodegradable and environmentally friendly liquid odour and vapour control
suppressant concentrate EN2000 (equivalent to Biosolve Pinkwater) will also be
used to control odour, if required.

— Piling spoil will be stockpiled, tested and disposed off-site in accordance with
appropriate waste classification guidelines (WSP 2021a)
Leachate management — Where water comes into contact with contaminated spoil, the resultant leachate
must be contained and managed in accordance with measures contained in section
3.7 of the CEMP (Buildcorp 2021))
— All leachate will be collected and pumped to on-site storage tanks for testing prior
to disposal off-site to a licensed liquid waste facility (WSP 2021a)
Asbestos Containing Material — In areas where a detailed investigation has indicated the presence of ACM,
excavated material will be spread out and sparrow picked to remove visibly
bonded asbestos.
— All monitoring and reporting of ACM, and corrective actions if necessary, will be
carried out in accordance with requirements outlined in the Asbestos Removal
Control Plan (WSP 2021a).
— Spoil will be analysed for asbestos. If present, it will be appropriately managed by
certified asbestos personnel (WSP 2021a)
5.2 MONITORING
Monitoring of air emissions will take place for the duration of construction works. An air quality monitoring program
will be prepared for the site and include the following pollutants:
— Dust
Project No PS123639 WSP
Air Quality and Odour Management Plan for CNSW Development, Wilson Park March 2021
Silverwater NSW Page 11
Buildcorp Group Contracting Pty Ltd— Odour — VOCs e.g. benzene — SVOCs, e.g. PAHs — Methane, carbon dioxide, carbon monoxide, oxygen and hydrogen sulphide, This section provides a description for monitoring the above pollutants. 5.2.1 DUST It is proposed to monitor dust as follows: — Visually A Buildcorp site engineer will conduct daily visual dust checks (minimum twice daily) on-site and along the site boundary to identify areas of dust generation during the day. The details will be logged on the daily log sheet and available to be inspected by the regulatory authorities. Where dust generated on-site is visibly impacting off-site receptors, the Buildcorp HSE Coordinator (Buildcorp HSEC) will be promptly informed. 5.2.2 ODOUR Odour screening along the site boundary during piling works, removal of earthing rods during electrical works and excavation activities will be undertaken on a daily basis (WSP 2021a). The results of the qualitative monitoring will be recorded on the log sheet and available to be inspected by regulatory authorities. Where odour is detected along the site boundary, the Buildcorp HSE Coordinator will be informed and where necessary works ceased until the source of odour is discovered and controlled. 5.2.3 VOCs VOCs may be emitted during piling works, removal of earthing rods during electrical works and excavation activities. (WSP 2021a). VOCs monitoring will be conducted during piling works, removal of earthing rods during electrical works and excavation works using a photoionisation detectors (PID). The proposed piling method adopted is CFA. A spiral auger will drill to the design termination depth without generating spoil at the surface. At termination depth, the auger will be lifted as concrete is pumped into the hole through the auger. Spoil will be generated at the surface as the augers are removed from the hole. This piling method does not enable the monitoring of gases in the soil / bore or during the removal of earthing rods as outlined in the CMP/RAP (DP 2020f). As such, an alternative method for VOC monitoring was provided by Douglas Partners (DP) and outlined in Section 3.9.2 of the WSP CEMP (WSP 2021a). For each bore, a record sheet will be completed including bore number, date of boring, depths of gas measurements, gas readings and actions. Prior to moving the piling rig to a new location, VOC monitoring will take place at the ground surface and 1.5 m above the ground surface to ensure gas levels are below the relevant Action Level (section 5.2.5) as outlined in the WSP CEMP (WSP 2021a). For benzene, the PID will be set to alarm at 1 part per million (ppm) [WSP 2021a] as presented in section 5.2.5. This Action Level correlates with the time weighted average (TWA) for benzene as prescribed in Safe Work Australia (2018), Workplace Exposure Standards for Airborne Contaminants. During piling works, removal of earthing rods during electrical works and excavation activities where VOC concentrations (e.g. benzene) remain greater than 1 ppm specific VOCs monitoring using Draeger tubes will also be undertaken (Section 3.9 of WSP 2021a). During excavation works, the method for conducting VOC monitoring is outlined in the WSP CEMP (WSP 2021a). Project No PS123639 WSP Air Quality and Odour Management Plan for CNSW Development, Wilson Park March 2021 Silverwater NSW Page 12 Buildcorp Group Contracting Pty Ltd
Stockpile monitoring will be undertaken if there are visual or olfactory signs of contamination from the stockpile (WSP 2021a) using a PID. Where gas readings persist above the Action Level (section 5.2.5), the stockpile will be temporarily covered. Daily monitoring of VOCs will be also conducted along the perimeter of the site using a PID and all results documented in a daily log sheet. The results of all qualitative monitoring will be recorded on the daily log sheet and available for inspection by regulatory authorities. 5.2.4 LANDFILL GASES Landfill gases (methane, H2S, CO and CO2) and oxygen (O2) may be emitted during piling works, removal of earthing rods during electrical works and excavation activities. (WSP 2021a). Gas vapour monitoring of landfill gases will be carried out during bore piling works, removal of earthing rods during electrical works, and excavation works of the pool basement and rainwater tank, using a landfill gas (LFG) multirae gas meter or equivalent. As referred to in section 5.2.3 during piling works and the removal of earthing rods (during electrical works), an alternative gas monitoring method is outlined in the WSP CEMP (WSP 2021a) and will be used during these works. Prior to moving the piling rig to a new location, LFG monitoring will take place at the ground surface and 1.5 m above the ground surface to ensure gas levels are below the relevant Action Level (section 5.2.5) as outlined in the WSP CEMP (WSP 2021a). During excavation works, the method for conducting LFG monitoring is outlined in the WSP CEMP (WSP 2021). 5.2.5 MONITORING ACTION LEVELS Monitoring action levels to be applied to the construction works (WSP 2021a) are: — Methane – equal to or more than 5 per cent (%) LEL — Carbon dioxide – equal to or more than 0.5% v/v — Hydrogen sulphide – equal to or more than 10 ppm — Carbon monoxide – equal to or more than 30 ppm — Oxygen – equal to or less than 19.5% v/v — Volatile organic compounds – equal to or more than 1 ppm. 5.2.6 ASBESTOS CONTAINING MATERIAL The WSP CEMP (WSP 2021a) has indicated that the risk posed by ACM in surface soils has been mitigated by works completed by Ford Civil Contracting (FCC). Buildcorp will confirm that the validation report for the Early Civil works for Stage 1 has been completed and approved before proceeding with works that may be impacted by the validation (WSP 2021a). Where ACM is encountered during CFA piling, removal of earthing rods during electrical works and excavation activities, asbestos monitoring will be conducted at locations to be determined by the certified occupational hygienist in accordance with the Asbestos Removal Control Plan (FCC 2020).

Buildcorp Group Contracting Pty Ltd7 COMMUNICATION STRATEGY
7.1 SITE INDUCTIONS AND TOOL BOX TALKS
Prior to undertaking any work at the Project site, all employees and subcontractors will attend an induction session which
will incorporate training on the procedures and controls measures associated with this Plan.
Further to site inductions, weekly toolbox meetings will be held to highlight the activities occurring during that week
including a briefing on potential high PM and odour generating activities and the control measures in place to control off-
site impacts.
7.2 AIR QUALITY REPORTING
All internal reports will be presented to the Buildcorp HSEC. Observational monitoring for dust and odour will be
reported on a daily basis to the Buildcorp HSEC.
Monthly air quality monitoring reports will be prepared for dust including graphical and tabular representation of data.
7.3 COMPLAINTS REPORTING
Air quality and odour complaints will be taken seriously and dealt with promptly. Each complaint will be investigated
and appropriate management measures put in place to prevent future occurrences.
Complaints will generally be managed in accordance with the Better Practice Guide to Complaint Handling (Australian
Government, Commonwealth Ombudsman, 2009) and Australian Standard 10002-2006 Customer Satisfaction—
guidelines for complaints handling in organisations (AS ISO 10002, 2006) with air quality and odour complaints being
lodged via a website and a phone hotline. The Community Involvement Plan (CIP) and CEMP (WSP 2021a) contain
details of the complaints handling process including a list of emergency contacts.

8 ON-SITE MANAGEMENT 8.1 TRAINING All employees, contractors and utility staff working on site will undergo site induction training relating to environmental issues, including dust and odour management. The induction training will address the following elements related to dust and odour management: — The existence and requirements of this plan — Work hours and the requirement for strict compliance — Delivery hours, trucking routes and loading/unloading locations — Air quality management measures — Project environmental responsibilities — Location of sensitive receptors — The importance of regular plant maintenance. Records would be kept of all personnel undertaking the site induction and training, including the contents of the training, date and name of trainer/s. Key staff will undertake more comprehensive training relevant to their position and/or responsibility. This training may be provided as toolbox training or at a more advanced level by the HSE Coordinator or delegated representatives. Air monitoring training may also be undertaken for VOCs (PID), landfill gases (Multirae) and dust (DustTrak) as required (WSP 2021a) to ensure the monitoring requirements of Section 3.9 of CEMP (WSP 2021a), CMP / RAP (DP 2020e) and the CEMP (WSP 2021a) are implemented appropriately. 8.2 INSPECTIONS AND AUDITING Audits (both internal and external) may be undertaken to assess the effectiveness of environmental controls, compliance with this sub plan and other relevant approvals, licences and guidelines. 8.3 NON-COMPLIANCES All air quality (dust) and odour monitoring data will be recorded and reviewed by the Buildcorp Project Administrator or HSE Coordinator. Issues of concern or non-compliance will be documented and discussed with the view of resolving the issue or determining a way forward. Where identified exceedances may impact the safety of people or property, work at the concerned site shall cease immediately. Typical emergency situations that may result in substantial air quality impacts may include substantial air quality events during out of hours works. These events are considered highly unlikely, however in the event of such an event occurring: — Work would cease immediately. — Any occupants would be evacuated with due consideration to safety. — The area would be secured to prevent unauthorised access. — A structural assessment would be undertaken and the results compared with any previous dilapidation survey. Project No PS123639 WSP Air Quality and Odour Management Plan for CNSW Development, Wilson Park March 2021 Silverwater NSW Page 17 Buildcorp Group Contracting Pty Ltd
— Where the damage is associated with construction, rectification work would be implemented or compensation agreed. An Environmental Incident Report form would be completed by the Project Site Manager or HSE Coordinator for any incident causing air quality impact on local residences. This form should identify the cause of the incident, the investigation of corrective actions and close out of the problem. 8.3.1 CORRECTIVE ACTIONS When required, corrective actions will be implemented in consideration of the Contamination Management Plan / Remediation Action Plan (DP 2020f) and Section 3.9 Ground Gas/Vapour of the CEMP (WSP 2021a). 8.4 REPORTING Records relating to air quality for the project shall be maintained for a period of five years in the site Environmental register or equivalent. These records shall include details related to air quality management, including: — Training/inductions records — Equipment inspections — Air quality monitoring reports — Audit or reviews — Communication regarding air quality management — Details of complaints 8.5 PLAN REVIEW Continual improvement of this plan will be achieved by the continual evaluation of environmental management performance against proposed control measures, environmental policies, objectives and targets for the purpose of identifying opportunities for improvement. The continual improvement process will be designed to: — Identify areas of opportunity for improvement of environmental management which leads to improved environmental performance — Determine the root cause or causes of non-conformances and deficiencies — Develop and implement a plan of corrective and preventative action to address non-conformances and deficiencies — Verify the effectiveness of the corrective and preventative action — Document any changes in procedures resulting from process improvement — Make comparisons with objectives and targets. Changes to this plan will be approved by Buildcorp representatives and stakeholders (if required) and documented in the document control section for each revision. A copy of the updated plan and changes will be distributed to all relevant stakeholders.
