4 1 Introduction 1.1 Background The Rizzani de Eccher Australia Pty Ltd/ Leighton Contractors Pty Ltd Joint Venture (RLJV) have been selected by the WestConnex Delivery Authority (WDA) to design and construct the M4 Widening Project (the Project) which will form the first stage of the WestConnex road project. This first stage of the project generally involves widening the existing M4 Motorway from three to four lanes in each direction for approximately 7.5 kilometers between the Pitt Street overpass at Parramatta and Homebush Bay Drive, Homebush. Major work is scheduled to commence in early 2015 and the M4 Widening is due to open to traffic in The WestConnex M4 Widening Environmental Impact Statement (EIS) (August 2014), assessed the impacts of construction, including section 6.4 with regards to ancillary facilities. Additionally Section 5.1 of the WestConnex M4 Widening Submissions Report (October 2014) built on this by providing a detailed review of potential impacts associated with the establishment and use of ancillary facilities during the construction period. Based on the construction activities proposed at the western end of the Project, an ancillary facility is proposed at Holroyd Oval. In line with the Department of Planning and Environment (DP&E) approval requirements, assessment and approval of proposed ancillary facilities for the Project is required prior to their establishment and use as an ancillary facility as outlined in this report. The construction activities in this section of the Project were previously assessed within the EIS and Submissions Report, as the location of the proposed facility is adjacent to construction footprint. Therefore relevant information from the EIS and Submissions Report has been used to inform this assessment. 1.2 Scope The purpose of this Environmental Review is to: Describe the change/activity (refer to Section 2); Assess the location against the ancillary facility requirements and other conditions specified in the Minister s Conditions of Approval (CoA) (refer to Section 3.3); Assess the environmental impacts associated with undertaking the activities confirming they are of minimal environmental impact (refer to Section 5); Recommend any site-specific environmental safeguards to be included in an Environmental Work Method Statement (EWMS) for establishing the facility (refer to Section 6); and Facilitate approval from the Secretary of DP&E (this assessment).

5 2 Description of Activity 2.1 Location and Setting Holroyd Sports Ground (Site 14) The proposed ancillary facility is located within Holroyd sports ground, which is located from Peel St Holroyd to Crescent St Holroyd, refer to Figure 2-1. The site is bounded by the M4 Motorway to the north, A Becketts Creek (concrete lined drain) to the south, and Robert/Peel St Holroyd are located to the west. Woodville Road is to the East of the proposed facility. Commercial /industrial properties surround the facility on the western, eastern and southern boundaries. The M4 Motorway separates the site from the closest residents which are located on Railway St Parramatta. The proposed site is located on the following land/portions of land: Lot 15 D (owned by Roads and Maritime); Lot 12 DP (owned by DP&E). A lease agreement has been established between the owners of the land and RLJV. A majority of the site is cleared grass that is regularly mowed, with some vegetation scattered throughout and along property boundaries. A row of trees is located to the north east of the site, however, this is outside the proposed facility boundary. An existing shared path is located adjacent to the M4 Motorway adjacent to the north of the proposed ancillary facility boundary at this location. Access to the shared path is currently available from Fox Street Holroyd to the west of the site, and Wigram Street Harris Park to the east of the site.

7 2.2 Description of proposed work Establishment of the ancillary facility site will involve: installation of erosion and sediment controls as required; installation of fencing and shade cloth/screening around the perimeter of the site; minor earthworks as required to construct level areas and creation of hardstand areas as required; Shared Path relocation works, including concrete works; installation of site sheds and storage containers and associated equipment and machinery; and installation of temporary onsite services as required (e.g. pump out sewer, water tanks if local water connection unavailable, and generators if electricity connection is unavailable). The following plant and equipment is indicative of what would be required for site establishment: hiab trucks; franna trucks; excavator; dozer; concrete agi; roller; light trucks; and utes. The ancillary facility as assessed in this report would have an approximate area of 1,500 square metres and would be used for staff amenities and sheds, materials storage and stockpile areas, and limited hazardous materials storage (e.g. minimal quantities of diesel, curing compound, oil, grease etc), refer to Figure 2-2. The main equipment and machinery to be used during operation of the facility would be trucks (hiabs and franna trucks) for the movement of personnel and materials. Access and egress to the ancillary facility would be from the M4 Motorway to the north of the site. The facility will be fenced and shade cloth/screening installed to prevent access to the site from the public including community members using the oval. Any lighting that is required will be oriented away from the Motorway traffic and surrounding businesses. The facility would be decommissioned and rehabilitated on completion of the works in consultation with the landowner to its current or an improved standard. This would be done in accordance with the CEMP and Ancillary Facility Management Plan (AFMP) and would include where applicable, any ripping; topsoiling of the area; weed control and seeding, planting, watering and maintenance; and removal of environmental controls. The lease agreement with the landowner includes the following requirements: Levelling out of the sports ground using fill material (suitable for its intended land use), refer Figure 2-3. Note: fill material won from the project will be tested at a NATA accredited laboratory and a validation certificate provided. Alternatively, a validation certificate for imported fill material will be obtained from the supplier of the material; Installation of boundary fencing on the drainage side of the sports ground (southern boundary); Reinstatement of the shotput pits, post RLJV construction works, (approximately March 2017).

Site establishment works are expected to take approximately two weeks. Operation of the ancillary facilities wouldd continue throughout the construction works in the western section of the Project. The facility would be decommissioned and rehabilitated on completion of the works in consultation with the landowner to its current or approved standard and in accordance with the lease requirements. All environmental controls would bee removed. The approved working hours for f the project (CoA D6) are as per the standard recommended construction hours as follows: 7:00am to 6:00pm Mondays to Fridays, inclusive; and 8:00am to 1:00pm Saturdays; and at no time on Sundays or public holidays. All site establishment works shall be carriedd out within these standard construction hours. Any out of hours works at the facility would be assessed and approved in accordance with CoA D8, including works in accordance with the Environmental Protection Licence (EPL) for the site (as issued).

10 3 Need and Planning Context 3.1 Need The ancillary facility at Holroyd Sports Ground, Holroyd as outlined in this report is required in order to facilitate construction works for the project through the provision of site sheds for personnel, storage of plant and equipment and hazardous materials storage, as well as the provision of materials storage and stockpiling areas in close proximity to the works. The site is proposed for the location of an ancillary facility for the project because of its proximity to the works (i.e. proximity to the M4 Motorway), its location outside of environmentally sensitive areas, and no vegetation clearing required for establishment of the site. 3.2 Planning Context The State Significant Infrastructure (SSI) application (no. SSI 6148) for the M4 Widening project was approved on 21 December 2014 by the Minister for Planning, subject to a number of conditions being met. Ancillary Facilities are defined in the project Instrument of Approval as follows: Temporary facility for construction, including for example an office and amenities compound, construction compound, batch plant (concrete or bitumen), materials storage compound, maintenance workshop, testing laboratory or material stockpile area. The proposed ancillary facility at Holroyd Sports Ground meets this definition of an ancillary facility as outlined above, being used as a combination of an office and amenities compound, construction compound, materials storage compound and material stockpile area. Condition of Approval (CoA) D28 details specific requirements relating to the location of ancillary facilities. An assessment of the proposed ancillary facility at Holroyd Sports Ground against these requirements found that the proposed site does not meet all the location criteria (refer to Section 3.3 below). As such, this document seeks to facilitate approval from the Secretary of the Department of Planning and Environment for the location of this ancillary facility prior to establishment. Site establishment, operation and rehabilitation works are proposed to be undertaken in accordance with the Project Environmental Management Plan and the Ancillary Facilities Management Plan (AFMP) for the project. 3.3 Ancillary Facilities Criteria Table 3-1 below provides an assessment of the proposed ancillary facility in accordance with the criteria provided in CoA D28, as well as other conditions of approval relevant to ancillary facilities (CoA D27, 29 and 30). The site is located adjacent to an active construction work area for the project. The site is level and would not directly or indirectly affect Aboriginal sites or historic heritage, and would require no vegetation disturbance. The proposed ancillary facility at Holroyd Sports Ground is considered to satisfy all location criteria, except for CoA D28 (a) and (f).

13 4 Consultation Consultation regarding the Project was undertaken during the EIS exhibition period. This assessment confirms and further informs the findings of the previous assessments undertaken in relation to construction activities located in this area of the Project. Targeted consultation with residents and businesses located within 200 m of the facility will be undertaken in accordance with the Community Involvement Plan five days prior to establishment works are expected to commence. The consultation will provide the surrounding community with details of the proposed activities for each stage of use (i.e. establishment, operational and decommissioning/rehabilitation). Additionally, project contact details would be provided with these notifications to assist with any inquiries or concerns that may be raised during establishment and/or operation of the ancillary facilities. Localised diversions of the Shared Path, including the section between High St/Junction Street, Harris Park to Fox Street Holroyd, were discussed at the Traffic and Transport Liaison Group (TTLG) on 5 March The Group was advised of the notification measures to be implemented including the directional signage that would be installed to notify users that the detour was in place. Direct consultation was undertaken with the landowners, Holroyd Council and Holroyd Sports Ground Amenities (Parks Committee). Table 4-1 provides a summary of the consultation and the outcome.

14 5 Environmental Assessment This section outlines potential environmental impacts relevant to the proposed ancillary facility based on the findings of the EIS, Submissions Report and subsequent investigations undertaken by RLJV for the M4 widening project. Where potential environmental impacts have been identified, the proposed environmental management measures to minimise potential impacts are outlined in Section Traffic and Transport The proposed ancillary facility is located to the south of the M4 Motorway. Access to the facility is proposed off the M4 Motorway. Section 8 of Appendix D of the EIS considers potential traffic and transport impacts of the M4 Widening Project. Table 8.5 of the EIS includes an assessment of predicted construction vehicle movements at various work sites along the project alignment, with works at this location (between Works between Pitt Street and Church Street Parramatta west side) assessed as requiring approximately up to 20 daily heavy vehicle movements during construction and between 6 and 30 light vehicle movements required daily during construction. Impacts from traffic associated with the establishment and operation of the proposed ancillary facilities at this location would be similar to that previously assessed for construction activities for this section of the Project, with approximately 5 heavy vehicle movements predicted per day in and out of the facility, as well as approximately 10 light vehicle movements daily associated with the movement of personnel in and out of the facility. Relevant traffic controls would be implemented to manage impacts to pedestrians and cyclists using the shared path with a temporary diversion established during the facility establishment. Therefore impacts associated with these proposed ancillary facilities are not expected to be significant. Impacts on local road traffic are expected to be negligible as construction vehicles will enter and exit the facility from the M4 Motorway with no direct access proposed from local roads. A vehicle management plan will be implemented for the facility for internal vehicle movements. With the surrounding areas being predominantly commercial/industrial, impacts from internal vehicles movements at this location are expected to be consistent with that assessed in the EIS. The Shared Path that runs parallel to the M4 Motorway will require a minor temporary diversion to allow access from the Motorway to the facility, refer to Figure 2-2. Consultation with the TTLG, which includes bike user groups regarding the diversion has been undertaken, refer to Section 4 for details. The impact on the users as a result of the diversion is expected to be minimal. Traffic impacts would be managed through the implementation of mitigation measures as per Table 6-1 of this assessment, to be incorporated into the EWMS during facility establishment. Additionally traffic impacts at this site during construction are to be managed in accordance with the CEMP and the Traffic and Access Management Plan (TAMP) for the project, with the local community to be notified in advance of proposed works. The CEMP and TAMP will be updated as applicable following the approval of the facility. 5.2 Noise and Vibration The facility is surrounded predominantly by industrial/ commercial receivers and the M4 Motorway. A noise and vibration assessment has been prepared by SLR Consulting Australia (refer Appendix A) to determine the potential impact on the receivers surrounding the facility. The assessment was based on the typical construction scenarios for the facility, i.e. site establishment; facility operation; and facility demobilisation. The assessment determined that the WestConnex M4 Widening Environmental Review Ancillary Facility Holroyd Sports Ground 11

15 noise predictions indicate that the worst-case LAeq(15minute) construction noise levels of up to 54 dba is expected at the most affected residential receivers. This level is less than the nominated Noise Management Level (NML) for this facility. The noise predictions indicate that worst-case LAeq (15 minute) construction noise levels of up to 68dBA are expected at the most affected industrial premises adjacent to the facility. The NML for the industrial premises is 75dBA. Predicted LAeq(15minute) noise levels at the worst-affected residential receivers show that compliance with the nominated NMLs are predicted to be achieved without implementing any additional mitigation measures. However, to prevent any exceedances that may occur, noise management measures outlined in Section 6 will be implemented. 5.3 Visual The landscape character of the site and surrounds at the location of the ancillary facility at Holroyd Sports Ground has been classified in the project Section 8 EIS as being within Landscape Zone 1 Parramatta/Holroyd (southern side), which is of moderate sensitivity due to the surrounding landscape and land uses being predominantly commercial and open space. However as assessed in the EIS, the potential visual impacts associated with the introduction of ancillary facilities in general across the project are considered to be low to moderate in terms of landscape and visual impacts, with some ancillary facilities having the potential to be visible from surrounding land uses and from within the Motorway corridor. The same is expected for the proposed ancillary facility at Holroyd Sports Ground. Due to the temporary nature of the works, the implementation of relevant mitigation measures, as well as retention of existing vegetation, visual impacts as a result of the ancillary facility are not expected to be significant. 5.4 Soils, Water and Waste Preliminary (Phase 1) and detailed (Phase 2) site assessments were undertaken by GHD (2013, 2014 respectively) as part of the EIS for the M4 widening project to identify potential contamination and acid sulfate soils (ASS) that may be impacted by the project. The location of the proposed ancillary facility has been assessed in the GHD report as Section 1 Pitt Street, Parramatta to Church Street, Granville. Soil sampling from eight hand auger holes were taken along the southern toe of the existing embankment of the M4 Motorway. The analytical results did not detect any asbestos in the samples and all samples reported chemical concentrations less than the adopted health-based investigation and screening levels for the intended land use. The Soil Contamination Report (Coffey 2015) prepared to address CoA B8 concludes that no unacceptable contamination risk has been identified in this Section of the project based on the findings of the Phase 1 and Phase 2 site assessments and exposure settings. During the use of the facility there will be minimal ground disturbance required, however, the CEMP and the unexpected finds procedure will be implemented during the use of the facility to manage potential contamination. The soil landscape at this location has been identified in the EIS as being predominantly disturbed terrain, which across the project includes areas of fill or heavy ground disturbance through general urban development. A Becketts Creek is located immediately adjacent to the south east of the proposed ancillary facility. Controls would need to be installed to protect this waterway and any drains within the site protected in order to avoid any direct or indirect impacts to this local waterway. In accordance with the EIS, provided appropriate controls are implemented during construction, short term impacts as a result of the works associated with the proposed ancillary facility are expected to be manageable and similarly have no material impact on receiving water quality. Similarly, there is not expected to be any impacts to groundwater as a result of proposed works as ground disturbance would be limited WestConnex M4 Widening Environmental Review Ancillary Facility Holroyd Sports Ground 12

16 to stabilisation of the ground surface as required for installation of temporary t site sheds and storage containers. Waste expected to be generated as a result of the establishment of the t ancillary facility would be as a result of minor ground disturbance; installation of temporary drainage d andd other erosion and sediment control structures; the placement of gravel road base as required; and construction/removal of the temporary Shared Path. In accordancee the CEMP Appendix B7 Waste and Energy Management Plan any a excavated soil materials that requires r disposal off site will be classified and disposed at an approved licenced facility. In the event that asbestos is identified during the works the Asbestos Management Strategy will be implemented which is contained in Appendix B. 5.5 Flooding and Hydrology Works at the ancillary facility are not expected to have any impacts on local flooding or hydrology and are not likely to be subject to t flooding as the facility is located above a the 200 year ARI flood level, refer to Figure 5-1 below. The assessmentt mapped the 1:100 year ARI, which demonstrates that during such an event the facility would be clear of flooding. As this is a more severe event, it can be concluded that during a 1:20 year flood event, the facility would not be impacted. Figure 5-1: Flood extent based on the 1% AEP 5.6 Biodiversity An ecological assessment of the M4 Widening project was undertaken as part of the EIS which has been used to inform this assessment. Areas of planted Figs and Tallowood have been identified within the row of trees along the northern boundary of the Holroyd Sports Ground, refer Figure 2-1. Both these vegetation types t are WestConnex M4 Widening Environmental Review Ancillary Facility Holroyd Sports Ground 13

17 distributed throughout the study area. The understorey is dominated by exotic flora including a wide range of environmental and noxious weed species. A habitat feature has been identified within the group of Fig trees in the stand to the north east of the proposed facility and adjacent to the M4 Motorway. No vegetation removal is required for the use of this facility. No endangered ecological communities were identified within or immediately adjacent to the proposed ancillary facility. Vegetation immediately surrounding the site to be retained would be appropriately protected during the works using no-go signage and flagging. Most of the project study area was found to support some level of noxious weed abundance. Therefore there is a risk these species could be spread during works associated with establishment and/or operation of the ancillary facility, therefore relevant mitigation measures would be implemented to manage potential impacts during works to control the spread of weeds. Due to the limited ecological value identified at the facility and minimal vegetation disturbance is proposed (i.e. no tree clearing), and the implementation of the unexpected threatened species finds procedure (included in Appendix C of this assessment), no significant impacts to flora or fauna are expected as a result of the works. 5.7 Heritage No registered sites were identified on the online Aboriginal Heritage Information Management System (AHIMS) within the project study area as assessed in the EIS for the M4 widening project, which includes the location where the ancillary facility at Holroyd Sports Ground is proposed. The field survey undertaken as part of the EIS confirmed that the project study area has low archaeological potential and no Aboriginal archaeological objects or Aboriginal places were identified within the project study area therefore no impacts to Aboriginal sites/objects places are expected as a result of these works. A number of non-aboriginal / historic heritage items were identified in close proximity to the facility as identified on the Parramatta LEP heritage map and LEP schedule 5 environmental heritage listing as follows: Vauxhall Inn (LEP reference: I11) located approximately 300m east of the ancillary facility; Federation Period cottage (14 Meehan Street, Granville) (LEP reference: I10) located approximately 233m north-east of the ancillary facility with the M4 Motorway between the facility and the property. The heritage sites are located approximately 300m and 233m respectively from the ancillary facility suggesting that no impact from construction activities at the proposed facility are expected. However, in the event of a discovery of a potential heritage item the unexpected heritage finds procedure (refer to the Heritage Management Plan) will be implemented. 5.8 Air Quality There is potential for dust to be generated during site establishment works and during operation of the proposed ancillary facility, which if uncontrolled has the potential to impact local air quality. It is expected that some dust may be generated at the site intermittently over the length of the project; however with the proposed mitigation measure in place as outlined in the CEMP and Appendix B6 Air Quality Management Plan (AQMP), the works are not expected to have any significant off-site impacts.

18 6 Environmental mitigation and management measures A range of environmental management and mitigation measures are identified in the various assessment and approval documents for the project, including the EIS, the Submissions Report, Conditions of Approval and RMS standard documents. Site specific management and mitigation measures have been adapted from these documents as relevant to the establishment; operation, decommissioning and rehabilitation of the proposed ancillary facility at Holroyd Sports Ground, as outlined in Table 6-1 below. The approved CEMP and sub plans will be implemented to manage the establishment, operation and rehabilitation of the facility. An EWMS for facility establishment has been developed and reviewed to incorporate relevant mitigation measures outlined in Table 6-1. Operation and rehabilitation of the ancillary facility will be undertaken in accordance with the CEMP and relevant sub plans including the Ancillary Facility Management Plan (AFMP).

Vegetation currently located between construction site compounds and adjacent residential areas will be retained where practicable to screen views Where possible, some screening fencing will be introduced between the residential premises and the work site to reduce the visual impacts. The ancillary facility and associated access points shall be rehabilitated to pre-construction condition or better, unless otherwise agreed by the landowner where relevant. Any areas temporarily disturbed during construction will be rehabilitated as soon as feasible and reasonable following the completion of construction/operation of the ancillary facilities. Soils, Water and Waste An erosion and sediment control plan will be prepared for the site in accordance with: Managing Urban Stormwater Soils and, Volume 1 Managing Urban Stormwater, 4th edition ( the Blue Book ). Managing Urban Stormwater Soils and, Volume 2D Main Road. Measures will be implemented during construction to minimise the risk of erosion, sedimentation and pollution. These measures may include: Designate no-go zones for construction plant and equipment Install upstream diversion channels to direct clean runoff from upstream catchments around or through disturbed areas (maintaining separation from runoff containing sediment). Install/line catch drains to carry any sediment laden runoff to appropriate sediment control measures. Remove cleared or excavated materials as soon as practicable after excavation and appropriately dispose of or stockpile off-site. Employ appropriate measures to prevent/minimise wind-blown dust from leaving the site (e.g. watering). Establish designated areas for plant and construction material storage within ancillary facility sites and other locations within the project area. Store all chemicals and fuels associated with construction in secure roofed and bunded areas. Transport of chemicals and fuels will be in bunded trays Pre- Responsibility Manager Manager Manager Manager Environment Manager Environment Manager Manager / Environment Manager Reference EIS/Submissions Report V-7 EIS/Submissions Report V-5 EIS/Submissions Report V-7 CoA D29 CoA D32(f)(iii) G36 Section 4.16 EIS/Submissions Report SWW-1 CoA D3 SWMP EIS/Submissions Report SWW-2 SWMP WestConnex M4 Widening Environmental Review Ancillary Facility Holroyd Sports Ground 18

22 ID Measure / Requirement When to implement Drip trays will be used when decanting fuels and chemicals Retain erosion and sediment controls until disturbed areas are stabilised. Fill material won from the project and used during re-establishment will be tested at a NATA accredited laboratory and a validation certificate provided; alternatively a validation certificate for imported fill material will be obtained from the supplier of the material. This information will be provided to the landowners prior to placement. Excavated material that is not suitable for on-site reuse or recycling will be transported to a site that may legally accept that material for reuse or disposal. Soils leaving the site will be waste classified so that correct resource recovery and or off-site disposal occur. All works shall be carried out in accordance with the project s Asbestos Management Strategy (refer to Appendix A), developed in accordance with the National Environment Protection (Assessment of Site Contamination) Measure 1999, which includes measures for the safe removal and disposal of known and undiscovered asbestos within the SSI footprint and related construction ancillary facilities, stockpile sites and site access. All wastes, including contaminated wastes, will be identified and classified in accordance with Environmental Guidelines: Assessment, Classification and Management of Liquid and Non-Liquid Wastes. Disposal of any non-recyclable waste will be in accordance with the Protection of the Environment Operations Act 1997 (POEO Act) and Waste Classification Guidelines: Part 1 Classifying Waste An Unexpected Discovery of Contaminated Land Procedure (see Appendix D) will be implemented if potentially contaminated land, spoil or fill is encountered. Works in the vicinity will be stopped or modified and will not recommence until the material has been analysed and management measures implemented.

24 7 Conclusion The RLJV project Team s proposed ancillary facility at Holroyd Sports Ground does not meet all of the ancillary facility location criteria as required by CoA D28, specifically: D28 (a) be located more than 50 metres from a waterway; and D28 (f) be separated from nearest residences by at least 200 metres (or at least 300 metres for a temporary batching plant). Therefore this assessment is being referred to the Secretary for approval prior to the establishment of an ancillary facility at this location. The proposed ancillary facility has been selected due to its location in close proximity to the construction works, and the minimal environmental impact associated with the establishment and operation. The environmental management measures outlined in Section 6 have been proposed to further protect the surrounding environment from potential impacts. As a result, with proper implementation of the management measures, it has been determined that the proposed activity is likely to have minimal environmental and community impacts.

This report presents the noise impact assessment relating to the M4 Widening Project works that are planned to be undertaken at Ancillary Site 14 (Halroyds). 1.2 Relevant Guidelines The construction noise goals adopted for this assessment are based on guidelines contained in the publications managed by the NSW Environment Protection Authority (EPA). The EPA guideline applicable to this assessment include: Noise Interim Noise Guideline - DECC 2009 (ICNG). 1.3 Terminology Specific acoustic terminology is used within this assessment. An explanation of common acoustic terms is included as Appendix A. 2 Works 2.1 Timing All works are proposed to be carried out during the day-time period of 7.00 am to 6.00 pm Monday to Friday, and 8.00 am to 1.00 pm Saturdays. 2.2 Equipment Table 1 details the construction scenarios, equipment used and corresponding sound power level data for the proposed activities. These phases do not necessarily relate to the steps of the process, rather they have been used as a planning tool to identify which element of the overall activity results in the likely worstcase noise impacts.

Guidance levels are given for airborne noise at residences and other sensitive land uses, including commercial and industrial premises. The quantitative assessment method involves predicting noise levels at sensitive receivers and comparing them with the guidance, or Noise Management Levels (NMLs). The various NML categories have been reproduced from the guideline and are presented in Table 2. Table 2 Noise Management Levels for Airborne Noise Time of Day Recommended standard hours: Monday to Friday - 7 am to 6 pm - Saturday 8 am to 1 pm Outside recommended standard hours. Commercial premises Industrial premises Note 1: Noise Management Level LAeq(15minute) RBL db RBL db 70 dba 75 dba The Rating Background Level (RBL) is the overall single-figure background noise level measured in each relevant assessment period (during or outside the recommended standard hours).

30 Rizzani Leighton Joint Venture M4 Widening Ancillary Site Facility - Site 14 (Holroyds) Noise Impact Assessment 16 April Ancillary Site 14 CNIS.docx Page Project Area Noise Management Levels The NMLs for the project area have been determined on the basis of unattended background noise monitoring previously undertaken in the project area as part of the M4 Widening project refer to the EIS technical paper, SLR Report R2 WestConnex M4 Widening, Pitt Street, Parramatta to Homebush Bay Drive, Homebush, and Operational Road Traffic Noise and Vibration Impact Assessment dated 23 July While this monitoring data is over two years old, the background noise levels in the vicinity are dominated by road traffic noise from the adjacent M4 motorway, and are unlikely to have reduced. This data is therefore considered acceptable to use for the purpose of determining appropriate noise management levels for the receivers adjacent to the proposed works (and may be slightly conservative). The LAeq(15minute) NMLs have been determined in accordance with the ICNG. The NMLs which are relevant to the Noise Catchment Areas (NCAs) (refer to Figure 1 and Figure 2) for the proposed works are detailed in Table 3.

The three-dimensional model includes source noise levels, ground topography, location of sources and receivers, acoustic shielding provided by ground topography, air absorption, ground effects and the duration of equipment usage within the assessment period. noise levels have been predicted at receiver locations in the vicinity of the proposed works. The resultant day time worst-case LAeq(15minute) noise level predictions are presented in Table 4. The results are presented as a summary of the worst-case impacts for each works scenario. The worstcase predictions (and subsequent mitigation measures) for each of the identified buildings relate to the facades/apartments orientated towards the works. The calculated noise levels will inevitably depend on the number of plant items operating at any one time and their precise location relative to the receiver of interest. In practice, the noise levels will vary due to the fact that plant will move about the worksites and will not all be operating concurrently. As such, noise levels are likely to be lower than the worst-case noise levels presented in Table 4. SLR Consulting Australia Pty Ltd

Accordingly, it has been predicted that compliance with the nominated NMLs will be achieved at all residential receiver locations for the proposed daytime operations. Noise predictions indicate that worst-case LAeq(15minute) construction noise levels of up to 68 dba are expected at the most affected industrial premises adjacent to the proposed ancillary facility. Accordingly, it has been predicted that compliance with the nominated NMLs will be achieved at all industrial receiver locations for the proposed daytime operations. Predicted LAeq(15minute) noise levels at the worst-affected receivers are shown in the maps in Appendix B. 4.3 Mitigation Measures Although no exceedance of the industrial / commercial NMLs is predicted, moderately high levels are predicted at the closest industrial / commercial receptor and thus, it is recommended that the following mitigation measures be implemented: Turn off plant which is not being used. Ensure plant is regularly maintained and replace equipment which becomes noisy. Arrange the worksite to minimize the use of movement alarms on vehicles and mobile plant. In addition, it is recommended that site inductions be given to all contractors taking part in the works. The inductions should highlight that as sensitive receivers are in close proximity to the works there is a need to limit noise where possible from shouting, vehicle stereos, radios, dropping of materials, slamming of doors, etc. SLR Consulting Australia Pty Ltd

33 Rizzani Leighton Joint Venture M4 Widening Ancillary Site Facility - Site 14 (Holroyds) Noise Impact Assessment 16 April Ancillary Site 14 CNIS.docx Page Cumulative Impacts Given the relatively small construction area and likely staged approach to the works, cumulative noise impacts are considered unlikely and further consideration of cumulative noise impact from the works is therefore not warranted. 5 Ground-borne Noise Assessment All of the proposed plant items are considered to have limited potential to cause adverse ground-borne noise impacts and as such have not been considered in this assessment.

34 Appendix A Report Page 1 of 2 Acoustic Terminology 1 Sound Level or Noise Level The terms sound and noise are almost interchangeable, except that in common usage noise is often used to refer to unwanted sound. Sound (or noise) consists of minute fluctuations in atmospheric pressure capable of evoking the sense of hearing. The human ear responds to changes in sound pressure over a very wide range. The loudest sound pressure to which the human ear responds is ten million times greater than the softest. The decibel (abbreviated as db) scale reduces this ratio to a more manageable size by the use of logarithms. The symbols SPL, L or LP are commonly used to represent Sound Pressure Level. The symbol LA represents Aweighted Sound Pressure Level. The standard reference unit for Sound Pressure Levels expressed in decibels is 2 x 10 5 Pa. 2 A Weighted Sound Pressure Level The overall level of a sound is usually expressed in terms of dba, which is measured using a sound level meter with an A weighting filter. This is an electronic filter having a frequency response corresponding approximately to that of human hearing. People s hearing is most sensitive to sounds at mid frequencies (500 Hz to 4000 Hz), and less sensitive at lower and higher frequencies. Thus, the level of a sound in dba is a good measure of the loudness of that sound. Different sources having the same dba level generally sound about equally loud. A change of 1 dba or 2 dba in the level of a sound is difficult for most people to detect, whilst a 3 dba to 5 dba change corresponds to a small but noticeable change in loudness. A 10 dba change corresponds to an approximate doubling or halving in loudness. The table below lists examples of typical noise levels Sound Pressure Level (dba) Typical Source Subjective Evaluation 130 Threshold of pain Intolerable 120 Heavy rock concert Extremely noisy 110 Grinding on steel 100 Loud car horn at 3 m Very noisy 90 site with pneumatic hammering 80 Kerbside of busy street Loud 70 Loud radio or television 60 Department store Moderate to quiet 50 General Office 40 Inside private office Quiet to very quiet 30 Inside bedroom 20 Recording studio Almost silent Other weightings (eg B, C and D) are less commonly used than Aweighting. Sound Levels measured without any weighting are referred to as linear, and the units are expressed as db(lin) or db. 3 Sound Power Level The Sound Power of a source is the rate at which it emits acoustic energy. As with Sound Pressure Levels, Sound Power Levels are expressed in decibel units (db or dba), but may be identified by the symbols SWL or LW, or by the reference unit W. The relationship between Sound Power and Sound Pressure may be likened to an electric radiator, which is characterised by a power rating, but has an effect on the surrounding environment that can be measured in terms of a different parameter, temperature. 4 Statistical Noise Levels Sounds that vary in level over time, such as road traffic noise and most community noise, are commonly described in terms of the statistical exceedance levels LAN, where LAN is the Aweighted sound pressure level exceeded for N% of a given measurement period. For example, the LA1 is the noise level exceeded for 1% of the time, LA10 the noise exceeded for 10% of the time, and so on. The following figure presents a hypothetical 15 minute noise survey, illustrating various common statistical indices of interest. Sound Pressure Level (dba) LAmax LA1 LA10 LAeq LA90 00:00 05:00 10:00 15:00 Of particular relevance, are: LA1 LA10 LA90 LAeq Monitoring or Survey Period (minutes) The noise level exceeded for 1% of the 15 minute interval. The noise level exceed for 10% of the 15 minute interval. This is commonly referred to as the average maximum noise level. The noise level exceeded for 90% of the sample period. This noise level is described as the average minimum background sound level (in the absence of the source under consideration), or simply the background level. The Aweighted equivalent noise level (basically the average noise level). It is defined as the steady sound level that contains the same amount of acoustical energy as the corresponding timevarying sound. When dealing with numerous days of statistical noise data, it is sometimes necessary to define the typical noise levels at a given monitoring location for a particular time of day. A standardised method is available for determining these representative levels. This method produces a level representing the repeatable minimum LA90 noise level over the daytime and nighttime measurement periods, as required by the EPA. In addition the method produces mean or average levels representative of the other descriptors (LAeq, LA10, etc). 5 Tonality Tonal noise contains one or more prominent tones (ie distinct frequency components), and is normally regarded as more offensive than broad band noise. SLR Consulting Australia Pty Ltd

35 6 Impulsiveness An impulsive noise is characterised by one or more short sharp peaks in the time domain, such as occurs during hammering. 7 Frequency Analysis Frequency analysis is the process used to examine the tones (or frequency components) which make up the overall noise or vibration signal. This analysis was traditionally carried out using analogue electronic filters, but is now normally carried out using Fast Fourier Transform (FFT) analysers. The units for frequency are Hertz (Hz), which represent the number of cycles per second. Frequency analysis can be in: Octave bands (where the centre frequency and width of each band is double the previous band) 1/3 octave bands (3 bands in each octave band) Narrow band (where the spectrum is divided into 400 or more bands of equal width) The following figure shows a 1/3 octave band frequency analysis where the noise is dominated by the 200 Hz band. Note that the indicated level of each individual band is less than the overall level, which is the logarithmic sum of the bands. Sound Pressure Level (dba) Appendix A Report Page 2 of 2 Acoustic Terminology People are able to feel vibration at levels lower than those required to cause even superficial damage to the most susceptible classes of building (even though they may not be disturbed by the motion). An individual's perception of motion or response to vibration depends very strongly on previous experience and expectations, and on other connotations associated with the perceived source of the vibration. For example, the vibration that a person responds to as normal in a car, bus or train is considerably higher than what is perceived as normal in a shop, office or dwelling. 10 Over:Pressure The term overpressure is used to describe the air pressure pulse emitted during blasting or similar events. The peak level of an event is normally measured using a microphone in the same manner as linear noise (ie unweighted), at frequencies both in and below the audible range. 11 Ground:borne Noise, Structure:borne Noise and Regenerated Noise Noise that propagates through a structure as vibration and is radiated by vibrating wall and floor surfaces is termed structureborne noise, groundborne noise or regenerated noise. This noise originates as vibration and propagates between the source and receiver through the ground and/or building structural elements, rather than through the air. Typical sources of groundborne or structureborne noise include tunnelling works, underground railways, excavation plant (eg rockbreakers), and building services plant (eg fans, compressors and generators). The following figure presents the various paths by which vibration and groundborne noise may be transmitted between a source and receiver for construction activities occurring within a tunnel Overall 1/3 Octave Band Centre Frequency (Hz) 8 Vibration Vibration may be defined as cyclic or transient motion. This motion can be measured in terms of its displacement, velocity or acceleration. Most assessments of human response to vibration or the risk of damage to buildings use measurements of vibration velocity. These may be expressed in terms of peak velocity or rms velocity. The former is the maximum instantaneous velocity, without any averaging, and is sometimes referred to as peak particle velocity, or PPV. The latter incorporates root mean squared averaging over some defined time period. Vibration measurements may be carried out in a single axis or alternatively as triaxial measurements. Where triaxial measurements are used, the axes are commonly designated vertical, longitudinal (aligned toward the source) and transverse. The common units for velocity are millimetres per second (mm/s). As with noise, decibel units can also be used, in which case the reference level should always be stated. A vibration level V, expressed in mm/s can be converted to decibels by the formula 20 log (V/Vo), where Vo is the reference level (10 9 m/s). Care is required in this regard, as other reference levels may be used by some organizations. 9 Human Perception of Vibration The term regenerated noise is also used in other instances where energy is converted to noise away from the primary source. One example would be a fan blowing air through a discharge grill. The fan is the energy source and primary noise source. Additional noise may be created by the aerodynamic effect of the discharge grill in the airstream. This secondary noise is referred to as regenerated noise SLR Consulting Australia Pty Ltd

41 1 Introduction This Asbestos Management Strategy has been developed to assist in compliance with environmental legislation and to control potential environmental impacts associated with management of asbestos that may be discovered in the course of construction of the WestConnex M4 Widening Major Civil Works Project (M4 Widening). It is prepared in accordance with the CEMP. This Strategy applies to all RLJV employees and sub-contractors. 1.1 Definitions Table 1-1 Definitions used in this Asbestos Management Strategy Term Asbestos Asbestos Containing Materials (ACM) Non-friable Asbestos Friable Asbestos Project Manager Competent Person Definition A naturally occurring silicate mineral that is a known carcinogen. Asbestos was used for its heat and corrosion resistant properties, mainly in buildings, ships and vehicles, from the 1950s to the 1980s. Any material containing more than a prescribed amount, (>0.5%) or as defined by local authorities in any form of asbestos. ACM that is not friable. Examples of non-friable asbestos could include flat, corrugated or compressed asbestos cement sheeting (roofing, exterior & interior wall cladding, eaves, fencing) and asbestos cement pipes such as electrical, water, drainage and flue pipes or vinyl floor tiles. ACM that: May be crumbled, pulverised, or reduced to powder by hand pressure. As a result of the work process becomes such that it may be crumbled, pulverised, or reduced to powder by hand pressure. Examples of friable ACM could include damaged plaster surfaces or thermal insulation. Note: This includes dust resulting from non-friable ACMs, raking or removal of plaster ceilings containing asbestos. The manager responsible for the health and safety of the workers (employees, contractors & subcontractors) and work activities undertaken by RLJV as part of the project / works. A person who, through training, qualifications, experience or a combination of these, has acquired the knowledge and skills that are needed for them to correctly and safely perform a task. 2 Background The M4 Widening Project covers 7.5 kilometres of existing road network between the Pitt Street overpass at Parramatta and Homebush Bay Drive, Homebush. The route covers an area of diverse characteristics and is surrounded by a number of potentially contaminating land uses including industrial complexes, landfill sites and WestConnex M4 Widening Major Civil Works SWMP Appendix F- Asbestos Management Strategy Page 4 of 15

42 railway facilities. The Phase 1 preliminary site assessment identified areas of high or high-moderate risk of contamination. The Phase 2 detailed site assessment identified the highest risk was the presence of asbestos. In the landscaped stockpile on the eastern side of the James Ruse Drive Junction In land to the north of the M4 Motorway adjacent to the east and west of Deniehy Street In an area of public access beneath the M4 Motorway to the east of Alfred Street 2.1 Types of Asbestos Asbestos is the name given to a group of minerals that occur naturally as bundles of fibres which can be separated into thin threads that break down to respirable size fibres. Four types of asbestos have been used commercially: Chrysotile - also known as white asbestos; Crocidolite - also known as blue asbestos; Amosite - usually has brown fibres; and Anthophylite usually has grey fibres. ACM refers to any material, object, product or debris that contains asbestos and it can take several physical forms. The two groups of ACMs likely to be encountered in the workplace include nonfriable asbestos and friable asbestos Non-friable Asbestos Non-friable asbestos products are made from a bonding compound (such as cement) mixed with a small proportion (usually less than 15%) of asbestos and are solid, rigid and not able to be crushed by hand (i.e. non-friable). Examples of non-friable asbestos products include: Flat, corrugated or compressed asbestos cement sheeting (roofing, exterior & interior wall cladding, eaves, fencing); Asbestos cement pipes such as electrical, water, drainage and flue pipes; Older caulking and glazing compounds; Older vinyl floor tiles and vinyl sheet flooring; Brake and clutch linings; Thermal boards around fireplaces; and Shingles & Wall siding Friable Asbestos Friable asbestos products are generally quite soft and loose and can be crumbled into fine material or dust with very light pressure, such as crushing with your hand. Examples of friable asbestos products include: WestConnex M4 Widening Major Civil Works SWMP Appendix F- Asbestos Management Strategy Page 5 of 15

45 4.1 Assessment of the work area Review the contamination management sub plan for areas of known asbestos contamination prior to commencing work that requires ground disturbance. These areas must be identified on site as No-Go zones. A permit is required to enter the area. Only authorised personnel are to enter these No-Go areas. If previously unidentified asbestos contamination is identified the following must be adhered to: 1. All work must cease as per the Unexpected Discovery of Contaminated Land Procedure and the Environmental Manager notified; 2. A suitable exclusion zones is to be established around the contaminated soil area; and 3. Warning signs are to be erected at all entrances and exists. 4.2 Identification and assessment of potential asbestos A specialist contractor to be engaged to correctly identify the material in consultation with NATA accredited testing laboratories and/or hygienists if necessary. Additional controls may installed as advised by the asbestos contractor to prevent further disturbance to the asbestos material while the material is being identified. Such controls may be spraying material with a sealant and/or wetting material and covering in plastic. 4.3 Management of identified asbestos Asbestos contamination management strategies are discussed in Section Management of Contaminated Soils of the Soil and Water Quality Management Plan. A summary of options is replicated in Table 4-1 below, and additional management actions detailed below. Table 4-1 Asbestos Contamination Management Strategies Contamination Issue Non-friable asbestos on surface (top 10cm) or non-friable asbestos exceeding 0.05% in top 0.5m Risks Inhalation health risks to construction workers and site users Migration via earthworks spreading asbestos impacts and extending health risks to surrounds Potential Strategies Strategy options/hierarchy may include: 1. Undertake emu picking to remove the non-friable asbestos fragments, if only the surface is impacted and subsurface is not impacted. 2. In consultation with WDA, remove and reuse impacted material in-situ below road pavement (e.g. buried below 0.5m). WestConnex M4 Widening Major Civil Works SWMP Appendix F- Asbestos Management Strategy Page 8 of 15

46 Friable asbestos on surface (top 10cm) or friable asbestos exceeding 0.001% in top 0.5m Inhalation health risks to construction workers and site users Migration via earthworks and wind spreading asbestos impacts and extending health risks to other areas 3. Excavate and dispose of material to a licensed landfill following waste classification. Asbestos management to be supervised by a WorkCover accredited Class A Licenced Asbestos Removalist for friable asbestos works and Class B Licenced Asbestos Removalist for non-friable works. Obtain specific asbestos management advice from a WorkCover accredited Licensed Asbestos Assessor (Coffey). Asbestos management to be supervised by a WorkCover accredited Class A Licenced Asbestos Removalist for friable asbestos works and Class B Licenced Asbestos Removalist for non-friable works. Specific actions to be implemented include; Safety team are to notify Work Cover as required. If asbestos has been positively identified and management in situ is unavailable the material shall be removed by an appropriately licensed asbestos removal contractor and transported by an EPA licensed waste transporter. The following procedure will be adopted where removal of asbestos material is required: 1. Area to be restricted to those completing the works and the area to be isolated and barricaded prior to removal works commencing and signage erected; 2. All contractors are to ensure that they have the correct PPE in accordance with Hygienists instructions for the asbestos removal task, (all PPE to be sealed in bag with contaminated material and removed and disposed appropriately); 3. Any removal work will utilise wet/damp methods only. Stockpiling of asbestos contaminated materials shall be avoided where possible. If stockpiling is unavoidable all stockpiles shall be kept damp and covered at the end of each day. 4. If machine is loading / excavating material it needs to be contained to hygienist s satisfaction. 5. If greater than 10 m2 of non-friable asbestos is found the Class-A licensed asbestos removalist will apply for a WorkCover NSW Non-friable Asbestos Removal Permit and remove the item and soil if necessary. 6. If friable asbestos is found, the Class-A licensed asbestos removalist will apply and receive a WorkCover NSW Friable Asbestos Removal Permit (Class B). WestConnex M4 Widening Major Civil Works SWMP Appendix F- Asbestos Management Strategy Page 9 of 15

47 7. All asbestos contaminated materials including PPE will be transported by an appropriately licensed transport to an appropriately licensed waste disposal facility. 8. Waste will be tracked and records kept in the waste management spreadsheet. 9. A clearance inspection shall be undertaken by an independent licenced asbestos assessor for friable work (Class A works) or for an independent competent person (depending on the type of removal work) for non-friable removal works. Once clearance reports are received from the Independent NSW Licenced Asbestos Assessor or competent person, only then work can proceed. Soil sampling for the detection of asbestos fibres released from fragments of non-friable asbestos such as fibro is not required where the non-friable asbestos product is in good condition. 4.4 Removing Asbestos All removal of verified asbestos contaminated material will be removed by an appropriately licenced asbestos removal contractor and transported by an EPA licensed waste transporter. Removal of friable asbestos must be conducted by asbestos contractors with a Class A licence and the removal of non-friable asbestos with by a contractor with a Class B licence from WorkCover. Removal of asbestos by a person who does not hold a Class A or Class B asbestos removal licence is permitted if the asbestos is: 10 m² or less of non-friable asbestos for example, asbestos sheeting Asbestos-contaminated dust or debris (ACD) that is not more than a minor contamination and is associated with the removal of 10 m² or less of nonfriable asbestos. The appropriately licenced asbestos removal contractor must prepare a work method statement, detailing the proposed work methodologies to be used in order to safely and effectively remove, enclose or encapsulate (as directed by Site Project Management) the asbestos containing materials. This method statement shall be submitted to Site Project Management and/or the nominated NSW Licenced Asbestos Assessor for Class A works or independent competent person for Class B for review and approval prior to commencing work on site. The method statement must include: - Work area isolation; - Removal methods; - Contamination control methods (wet methods and decontamination procedures); and - Health and safety procedures (respiratory protection). WestConnex M4 Widening Major Civil Works SWMP Appendix F- Asbestos Management Strategy Page 10 of 15

48 All friable asbestos material (any material that contains asbestos and is in the form of a powder or can be crumbled, pulverised or reduced to powder by hand pressure when dry )shall be: - isolated and secured by installing warning signs and temporary barricades around the affected area to minimise the potential for exposure of site personnel and/or the public to airborne fibres. - kept damp or sealed with PVA glue and covered where practicable with plastic sheeting. - collected and sealed in 200-micron thick, appropriately labelled, plastic bags - double wrapped in 200-micron thick plastic bags - in bags that weigh not more than 25 kilograms, and are less than half full - stored in a secure area, awaiting removal; and - removed from the site as soon as practicable by a licensed Class A contractor. All non-friable asbestos waste (i.e. any material other than friable asbestos material that contains asbestos) shall be: - Kept damp (prevent runoff water) - collected, labelled and sealed using appropriate plastic or leak proof containers - stored in labelled, plastic-lined bins that are covered, or leak-proof containers that are covered - placed in bins or trucks that are large enough to contain full sheets without breaking them - stored in a secure area; and - removed from the site by a licensed contractor (Class A or Class B) as soon as practicable. Buried ACM will be managed as follows: Asbestos only presents a risk if fibres may become airborne and breathed in. Where non-friable or friable asbestos is present in soil at depth (greater than 0.5m below the soil surface), the asbestos material may not be disturbed unless it is for the purpose of site remediation, redevelopment or site management. This would be considered on a case-by-case basis in consultation with an appropriately licensed asbestos assessor. Where asbestos is found at depths between 10cm and 0.5m, a site-specific assessment would be undertaken by the specialist consultant to assess an appropriate management strategy. Where asbestos is distributed throughout the soil stratum, the NEPM 1999 (amended 2013) identifies criteria for asbestos in soil that are unlikely to generate elevated levels of airborne asbestos. These criteria provide a useful guidance for assessment and clean-up. Specialised advice would be obtained. WestConnex M4 Widening Major Civil Works SWMP Appendix F- Asbestos Management Strategy Page 11 of 15

49 Respirators used during the removal of asbestos should comply with the AS/NZS 1716 Respiratory Protective Devices and selected, used and stored in accordance with AS/NZS 1715 Selection, Use and Maintenance of Respiratory Protective Devices. 4.5 Transporting and Post Removal of Asbestos The appropriately licenced asbestos removal contractor must give a minimum 5 days notice to WorkCover regarding the removal of asbestos and obtain a Friable Asbestos Removal Permit. This permit will be obtained prior to any work occurring on the stockpile, as the risk of identifying and removal of asbestos is likely. It should be noted that a Non-friable Asbestos Removal Permit is not required when there is less than 10 m 2 of the material. All asbestos waste must be transported in a covered leak-proof vehicle and must be disposed of in a manner approved by EPA and at a waste facility licensed by the EPA to accept asbestos waste; After completion of removal works at each location personnel must undertake the following decontamination procedures if they have been involved in removal of asbestos: remove & dispose of all PPE and wash hands, face and exposed skin areas; After removal works have been completed, the area must be inspected to ensure all asbestos have been removed to a satisfactory standard. The process for validation should be as follows: - NSW Licenced Asbestos Assessor for Class A works or independent competent person for Class B to conduct visual inspection. - NSW Licenced Asbestos Assessor for Class A works or independent competent person for Class B to conduct clearance air monitoring within work area where appropriate. Where clearing soil, then soil samples may also be appropriate. - NSW Licenced Asbestos Assessor for Class A works or independent competent person for Class B to conduct clearance that all equipment has been decontaminated. At the completion of visual inspection and sampling, the NSW Licenced Asbestos Assessor for Class A works or independent competent person for Class B will issue a clearance report that demonstrates that removal works have been effectively carried out. A Clearance Certificate will be issued to certify that works have been completed satisfactorily and it is safe to resume normal operations. Waste transfer dockets for all material removed from the works shall be provided and a copy kept within the Project s waste management documentation. 5 Responsibilities The management of the discovery, handling and removal of asbestos is the responsibility of the specialist consultant with overview by the Safety Team. WestConnex M4 Widening Major Civil Works SWMP Appendix F- Asbestos Management Strategy Page 12 of 15

50 The Environmental Team are responsible for the tracking and appropriate disposal of asbestos; 6 Training The project induction will include details on asbestos management and what to do in the event of suspected asbestos on site. Ongoing training in asbestos management and the unexpected discovery of asbestos procedure will be implemented at regular intervals through the construction phase of the project. RLJV will maintain a record of the qualifications of the asbestos removalist s workers as part of the induction process to assure only competent and qualified workers are undertaking this work. 7 Consultation 7.1 Community In the event of a suspected asbestos or ACM discovery, the Community Manager (CM) will be immediately notified. The CM is to record the proposed actions taken by the site personnel and prepare a notification to the community impacted by the works. 7.2 Workers The Project Manager is to make sure that all RLJV staff, workers and subcontractors who are impacted by the disturbance of asbestos or ACM are told of: the presence and location of asbestos within the workplace the proposed immediate response to be taken to minimise risks the sampling process to be undertaken by a competent person how to access the Asbestos Register the risk associated with the presence of asbestos the measures to control the asbestos risks the Asbestos Management Plan requirements All RLJV staff, workers and subcontractors will be consulted with during the removal of the asbestos or ACM from the site. These personnel are to be informed of sampling and monitoring results and be involved in any risk analysis activities. Consultation will include the development and the review of the safe work method statement supplied by the appropriately licenced asbestos removal contractor. WestConnex M4 Widening Major Civil Works SWMP Appendix F- Asbestos Management Strategy Page 13 of 15

51 8 Incident management and emergency procedures 8.1 Incident Reporting Any incident or near miss resulting in an exposure or potential exposure must be reported immediately and an Incident Report Form completed. The information collected will form the basis of the asbestos register and will include a marked up site plan. 8.2 Emergency Procedures Emergency procedures on site will cover actions to be taken when asbestos is uncovered, catastrophic events occur or air monitoring indicates high levels of airborne asbestos fibre. The emergency procedures contained in the CEMP will be implemented. It is important to remember that the first priority must always be the safety of workers or others involved in the events. Uncovering of asbestos may occur due to human error or to catastrophic event. Catastrophic events may include but not limited to: Explosion Industrial Accident Failure of construction structures Failure of an asbestos control (i.e. encapsulation, equipment etc) Earthquake Flood Fire All emergency action should take place as soon as possible after the event. The first priority is to stabilise the situation and to prevent further hazard or worker exposure. 9 Monitoring There are three different types of air monitoring required to be completed for asbestos work; this monitoring will be undertaken by the NSW Licenced Asbestos Assessor for Class A works or independent competent person for Class B. 1. Occupational monitoring- is measuring airborne respiratory fibres in the worker s breathing zone and comparing it with the exposure standard. This type of monitoring is generally not carried out during removal work. The exposure standard for all types of asbestos is 0.1 fibres per millilitre of air; 2. Control monitoring; - is monitoring occurs during asbestos remediation or removal work; Air monitoring shall be carried out for all friable asbestos removal. It may also be necessary for removal of non-friable asbestos or ACM, if there is an increased risk to the public or workforce due to the location of the site. Air monitoring shall be conducted in accordance with the Guidance Note on the Membrane Filter Method for Estimating Airborne Asbestos Dust, 2nd Edition [NOHSC: 3003 (2005)] WestConnex M4 Widening Major Civil Works SWMP Appendix F- Asbestos Management Strategy Page 14 of 15

52 Air monitoring shall be conducted before and during Class A asbestos removal work. However, it is not required before friable asbestos removal work commences when the glove bag removal technique is used (refer to the Code of Practice How to Safely Remove Asbestos). Air monitoring shall be carried out as part of a clearance inspection, e.g. at the conclusion of the asbestos removal work. Air monitoring shall be carried out by an Independent NSW Licenced Asbestos Assessor or competent person engaged by RLJV. Any exceedances during control monitoring must follow the guidance provided in the following table; Action Level (airborne asbestos fibres/ml) Action Less than 0.01 Between 0.01 and 0.02 More than 0.02 Continue with control measure Review control measure Stop removal work and find the cause Code of Practice for the Safe Removal of Asbestos [NOHSC:2002 (2005)] The clean up goal for contaminated land is asbestos in soil should not exceed 0.001% weight for weight (w/w) for FA and AF and should not exceed 0.05% w/w for ACM (Western Australia Guidelines (2009)) 3. Clearance monitoring; - is monitoring that occurs following asbestos removal work. All friable asbestos removal work must have a clearance certificate at the completion of work. The clearance certificate must be completed by an NSW Licenced Asbestos Assessor for Class A works or independent competent person for Class B and the results assessed by a laboratory accredited by NATA for the test method. All waste will be tracked from origin to approved landfill destinations via waste tracking forms. The approved waste tracking forms will be retained to record the date of asbestos removal, and identify the licensed waste transport contractor and destination of the wastes from the worksite.
