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 kilometres 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 (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. Both the Environmental Impact Statement (EIS) and Submissions Report identified a number of ancillary facilities including a proposed location at Alfred Street (site 3). In line with the Department of Planning and Environment (DP&E) approval requirements, further assessment and approval of the proposed ancillary facilities for the project, including at Alfred Street (site 3) is required prior to their establishment and use as an ancillary facility for the project, as outlined in this report. It is noted that the ancillary facility at Alfred Street (site 3) was previously assessed as an ancillary facility within the EIS and Submissions Report. 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 site against the ancillary facility site 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 site (refer to Section 6); and Facilitate approval from the Secretary of DP&E (this assessment). WestConnex M4 Widening Environmental Review Ancillary Facility Site 3 1

5 2 Description of Activity 2.1 Location and Setting The proposed Alfred Street ancillary facility (site 3) would be located to the east of Alfred Street, Granville, on land currently owned by Roads and Maritime Services. The site is bounded by Alfred Street to the west, A Becketts Creek to the north, houses along A Beckett Street to the east, and the M4 Motorway to the south (with a portion of the site extending into land located beneath the M4 Motorway). The size of the facility is approximately 5,100 square metres. The proposed site is located on the following land/portions of land: Lot 6 DP1250; Lot 1, DP809505; Lot 1 and 2 DP207490; and Lot 21, 29, 39, 41, and 48 DP This site is within the footprint of the area assessed in the EIS and Submissions Report for ancillary facility/compound site 3 (refer to figure 2-1 below), however the previously assessed portion of land to the south of the M4 Motorway is no longer proposed to be used. Refer to Figure 2-2 for the proposed layout. 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 in the southern portion of the proposed site, as well as in the northern portion of the site along the boundary with A Becketts Creek. The surrounding area is primarily residential with some road infrastructure (i.e. the M4 Motorway). Detached residential dwellings are located adjacent to the site on Alfred Street to the north-west, A Beckett Street to the east, north of A Becketts Creek, and to the south of the site on the other side of the M4 Motorway along Onslow Street. An existing shared path is located beneath the M4 Motorway adjacent to the south of the proposed ancillary facility boundary at this location. Access to the shared path is currently available from Alfred Street to the south-west of the site, and A Beckett Street to the south-east of the site.

7 2.2 Description of proposed work Establishment of the ancillary facility will involve: establishment of no go zones within vegetated areas around the perimeter of the site as required; installation of erosion and sediment controls as required; installation of fencing around the perimeter of the site as required; minor earthworks as required to construct level areas and creation of hardstand areas as required using clean (i.e. contamination free) material; 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 would be likely required for site establishment: bogey trucks; graders and rollers; and excavators. The following plant and equipment would be likely required for site operation: bogey trucks; and excavators. The following plant and equipment would be likely required for site demobilisation: equipment for revegetation; bogey trucks; and excavators. The ancillary facility at site 3 assessed in this report would have an approximate area of 5,100 square metres and would both be used for staff amenities and sheds, materials storage (including bonded asbestos containing materials (bonded ACM)) 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. Any lighting that is required will be oriented away from the surrounding properties. Access and egress to site 3 would be predominantly from Arthur Street via A Beckett Street to the east of the site. The facility would be decommissioned and rehabilitated on completion of the works in consultation with WDA 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.

9 2.3 Duration and Timing The ancillary facility is proposed to be established from late November 2015 following approval from DP&E. and in accordance with the conditions of approval for the project. Site establishment works are expected to take approximately two weeks at this location. Operation of the ancillary facility would 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 WDA to its current or approved standard. All environmental controls would be removed. The expected timing for decommissioning is March The approved working hours for 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 carried out within these standard construction hours. Any out of hours works at the site 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). WestConnex M4 Widening Environmental Review Ancillary Facility Site 3

10 3 Need and Planning Context 3.1 Need The ancillary facility at Alfred Street (Site 3), Granville, 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), existing access to the locations via the local road network, its location outside of environmentally sensitive areas, and minimal vegetation clearing requirements 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 Alfred Street (Site 3) 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 Alfred Street (Site 3) 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 Construction Environmental Management Plan and the Construction Ancillary Facilities Management Plan (AFMP) for the project. 3.3 Ancillary Construction Facilities Criteria Table 3-1 below provides an assessment of the proposed ancillary facility at Alfred Street (Site 3) 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 within the construction work area for the project as identified in the Submissions Report. The site is generally level and would not directly or indirectly WestConnex M4 Widening Environmental Review Ancillary Facility Site 3

11 affect Aboriginal sites or historic heritage, and would require minimal (if any) vegetation disturbance. The proposed ancillary facility at Alfred Street (Site 3) is considered to satisfy all location criteria, except for CoA D28 (a), (d), (f), (g) and (j).

15 4 Consultation Consultation regarding the Project was undertaken during the EIS exhibition period. Further investigations into the proposed ancillary facilities for the Project was undertaken as part of the Submissions Report in order to address commitments made in the EIS and/or address comments received from the community and government agencies during consultation. This assessment confirms and further informs the findings of the previous assessments undertaken in relation to Site 3. 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. Once the ancillary facility is approved, the surrounding community would be informed of the upcoming establishment and operational works, including the proposed use, duration and size of the facility as outlined in this assessment. 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 facility. WestConnex M4 Widening Environmental Review Ancillary Facility Site 3 12

16 5 Environmental Assessment This section outlines potential environmental impacts relevant to the proposed ancillary facility at Alfred Street (Site 3) 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 at Alfred Street (site 3) is located to the north of the M4 Motorway. Access to the Alfred Street facility is proposed off Arthur Street to the east of the site, via A Beckett Street. This access was selected to minimise the impact on the residence located on the western boundary on Alfred Street. Section 8.1 of the EIS considers potential traffic and transport impacts of the M4 Widening Project. Table 8.2 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 A Beckett Street and the western abutment of the bridge over Carlingford Rail Line) assessed as requiring approximately up to 10 daily heavy vehicle movements during construction and between 12 and 50 light vehicle movements required daily during construction. Impacts from traffic associated with the establishment and operation of the proposed ancillary facility at this location would be similar to that previously assessed, with approximately 30 heavy vehicle movements predicted per day in and out of this site, as well as approximately 15 light vehicle movements daily associated with the movement of personnel in and out of the site. Relevant traffic controls would be implemented to manage impacts to pedestrians and cyclists using the shared path beneath the M4 Motorway to the south of the proposed Alfred Street ancillary facility (Site 3). Therefore traffic impacts associated with the proposed ancillary facility are not expected to be significant. With the surrounding areas being predominantly residential, impacts on local road traffic at this location are expected to be consistent with that assessed in the EIS. 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 for this location for site establishment works. Additionally traffic impacts at this site during construction are to be managed in accordance with the construction Traffic and Access Management Plan (TAMP) for the project, with the local community to be notified in advance of proposed works impacting local residential streets. The number of construction personnel working at the facility will be approximately 3-4 workers. Parking will be available on site for these personnel, therefore minimising the impact to residents. Access to the facility will generally be within standard construction hours. If the facility is required to be used out of standard hours the out of hours procedure will be implemented and the surrounding community notified. WestConnex M4 Widening Environmental Review Ancillary Facility Site 3 13

17 5.2 Noise and Vibration Section 8.2 of the EIS identifies noise and vibration impacts of the project, dividing the project area into a number of Noise Catchment Areas (NCAs) and identifying Noise Management Levels (NMLs) to be implemented at sensitive receivers impacted with the project. The proposed ancillary facility at Alfred Street (Site 3) is surrounded predominantly by residential receivers within NCA.A02_07N, with some commercial/industrial receivers scattered throughout this NCA. Additionally the Parramatta Local Environmental Plan (LEP) land use zoning map identifies both a recreation area and a place of worship to the north of Site 3 on the opposite side of A Becketts Creek. A noise and vibration assessment has been prepared by SLR Consulting Australia (2015) (refer Appendix F) to determine the potential impact on receivers. The assessment was based on the typical construction scenarios, i.e. establishment; operation; and demobilisation. The assessment determined that the noise predictions indicate that the worst-case LAeq(15minute) construction noise levels of up to 79dBA (during facility establishment) is expected at the most affected residential receivers. The noise is generated during hardstand preparation and will be intermittent and of short duration occurring for approximately two days. The SLR report predicted the long term facility operations to produce moderate typical works-case NML exceedances of up to 9dB at receivers located immediately adjacent to the ancillary facility. As such, noise levels are likely to be lower than the worst-case noise levels presented in the assessment. In light of this, a noise mound is proposed to be constructed around the boundary of the facility following hardstand establishment. Barriers, such as noise mounds, that break the line of sight from the receiver to the noise producing plant can typically mitigate noise levels by between 5 db and 10 db. An assessment of cumulative noise impact has been included in the noise and vibration assessment (Appendix F). The main construction works that will be undertaken in the vicinity of the proposed ancillary facility will include piling, substructure and superstructure activities. These works are to be undertaken on the opposite side of the Motorway from the proposed ancillary facility, on the southern side of the existing viaduct. The Site 3 ancillary facility would likely experience an increase of up to 3 db to predicted noise levels when mainline works are occurring simultaneously. It is proposed that the existing background noise from the Motorway, and the mitigation measures detailed, including the erection of the noise mound will sufficiently mitigate cumulative impacts on noise receivers in this location. An assessment of the impact of construction traffic has been included in the Noise and Vibration Assessment and it has been predicted that a maximum increase in road traffic noise of 14.9dB can be expected as a result of the operation of the facility. In order to minimise this impact, traffic movement for the facility will be restricted to standard construction hours, which coincides with the peak hour of vacancy of residential properties, thus it is expected that most houses will be empty during the haulage operations. Increased traffic movement will form part of the consultation to be undertaken with adjacent residences, and this route will be included in the Local Road Dilapidation Report and Traffic and Access Management Plan.

18 5.3 Visual The landscape character of the site and surrounds at the location of the ancillary facility at Alfred Street (Site 3) has been classified as being within Landscape Zone 2 Harris Park Granville, which is of high sensitivity due to the surrounding landscape and land uses being predominantly residential, as well as the landscape associated with A Becketts Creek corridor which is near the facility. 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 Alfred Street (Site 3). Mitigation measures as per the CEMP and relevant sub plans would be implemented to manage any visual and landscape character impacts as a result of the works. This would include in the event of out of hours works being required and the facility being used at night time, temporary lighting would be set up in such a manner as to reduce light spill to adjacent residential receivers. Due to the temporary nature of the works, the implementation of relevant mitigation measures, and the post demobilisation revegetation works, visual impacts as a result of this 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 at Alfred Street (Site 3) has been assessed in the GHD report as Section 2 Church Street to Deniehy Street, Granville. No samples were taken or assessed at the location of the proposed ancillary facility at Alfred Street (Site 3), however information from the GHD report for this section (Section 2) of the alignment is deemed sufficient to inform this assessment. Asbestos fragments and fibres, as well as polycyclic aromatic hydrocarbons (PAHs) in fill soils were recorded in this section of the alignment. This location was also identified as having hydrocarbons in groundwater with potential soil impacts, and a number of contaminants identified in sediments in A Becketts Creek at this location. Additionally a publicly accessible area to the east of Alfred Street beneath the M4 Motorway has been identified as being a high risk contamination area due to asbestos, which is located immediately adjacent to the southern portion of the proposed ancillary facility at Alfred Street (Site 3). The GHD report recommends further investigation of the level and extent of asbestos at this location which would be undertaken prior to site establishment works to determine additional controls and/or remedial action if required. Therefore with the implementation of mitigation measures, including those specific to asbestos management at the proposed ancillary facility at Alfred Street (Site 3), and due to the limited ground disturbance as a result of the works, contamination impacts are not expected. 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 WestConnex M4 Widening Environmental Review Ancillary Facility Site 3 15

19 heavy ground disturbance through general urban development. However based on the minimal scope of ground disturbance at the facility; impacts to PASS are not anticipated. A Becketts Creek is located immediately adjacent to the north of the proposed ancillary facility at Alfred Street (Site 3). Controls would be installed to protect this waterway and any drains within the facility 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 at either site as ground disturbance would be limited to stabilisation of the ground surface as required for installation of temporary site sheds and storage containers. Surface erosion and sedimentation will be managed through the implementation of an Erosion and Sediment Control Plan (Appendix D) for this ancillary facility, As per the EIS, waste expected to be generated as a result of the establishment of this temporary ancillary facility would be as a result of minor ground disturbance, installation of temporary drainage and other erosion and sediment control structures and the placement of gravel road base as required. In accordance with the Phase 2 contamination assessment any excavated soil materials from the facility are likely to be classified and disposed of as General Solid Waste (GSW), with asbestos and/or PASS managed accordingly if identified during the works. The Asbestos Management Strategy to be implemented for the project is included in Appendix A of this assessment. Stockpiling of bonded ACM is proposed to be undertaken in this location. The management of bonded ACM stockpiles will be undertaken in accordance with the Soil and Water Management Plan Appendix F - Asbestos Management Strategy, included as Appendix A to this document. 5.5 Flooding and Hydrology Works at the proposed ancillary facility at Alfred Street (Site 3) are not expected to have any impacts on local flooding or hydrology and are not likely to be subject to flooding throughout the works as the facility is predominantly located above the 20 year ARI flood level, with a small section of the northern portion of the proposed facility at Alfred Street (Site 3) located within the 20 year ARI flood level, refer Figure 2-1. However given the short term and temporary nature of the proposed works, impacts from flooding are not expected during site establishment or operation of the ancillary facility. Relevant mitigation measures will be implemented as presented in Table 6-1 and a flood contingency plan as required by CoA D28 (j), refer Appendix B. The contingency plan specifies storage requirements for particular materials, for example, hydrocarbons and chemicals to be stored above the 20 ARI flood level. 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. A further Ecology Report WestConnex M4 Widening Environmental Review Ancillary Facility Site 3 16

20 prepared by Cumberland Ecology (12 August 2015) has assessed the flora and fauna at the facility (refer to Appendix F). The report concludes that no threatened species are present within the ancillary facility at Alfred Street (Site 3), one habitat feature was identified. Tree removal is not proposed for this ancillary facility. Revegetation of grass in the disturbed area will occur post-demobilisation as required.vegetation within and immediately surrounding the facility to be retained would be appropriately protected during the works. Noxious weed abundance was observed at the northern end of the proposed ancillary facility at Alfred Street (Site 3). Therefore there is a risk these species could be spread during works associated with establishment and/or operation of the facility. It is proposed that this area will not be disturbed to minimise any such risk. Due to the limited ecological value and given the minimal vegetation disturbance proposed, as well as the implementation of relevant mitigation measures as per Table 6-1 including 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 proposed ancillary facility at Alfred Street (Site 3). 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 this site as identified on the Parramatta LEP heritage map and LEP schedule 5 environmental heritage listing as follows: T.C. Barker and Son Pottery at 3 A Beckett Street (LEP reference: I83) located approximately 230m east of the Alfred Street ancillary facility (Site 3); Latalda at 20 A Beckett Street (LEP reference: I84) located approximately 85m south-east of the Alfred Street ancillary facility (site 3); Conjoined residences at 22 and 24 A Beckett Street (LEP reference: I85) located approximately 65m south-east of the Alfred Street ancillary facility (site 3. The proposed access to this site would involve trucks and light vehicles passing in front of these locations, however these are set back from the road with no impacts expected as a result of the proposed works at these locations. 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 WestConnex M4 Widening Environmental Review Ancillary Facility Site 3 17

21 measure in place, the works are not expected to have any significant off-site impacts. WestConnex M4 Widening Environmental Review Ancillary Facility Site 3 18

22 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 Alfred Street (Site 3) as outlined in Table 6-1 below.

This shall include; Induction training would include the education of staff on noise impacts and associated mitigation measures. Construction of a noise mound around the perimeter of the site. The use of temporary barriers / hording around stationary/localised items of plant (may include stockpiling areas or loading areas). This may include the use of earth mounds or similar to minimise noise to residents. Loading and unloading should be carried out away from sensitive receivers, as far as practicable. Work areas (stockpiling, fabrication, maintenance etc) within compounds should be located as far as practicable from nearby sensitive receivers. Avoid noisy plant working simultaneously in close proximity adjacent to sensitive receivers. The facility shall be designed to promote one-way traffic where possible so that vehicle reversing movements are minimised. Truck routes to and from the ancillary facility will be via major roads where possible. Unless required for technical reasons, undertake noisy activities during the day, or early in the evening if required to be undertaken at night; avoiding short sharp sounds from impacts. Monitor noise at nearby receivers generated from the ancillary facility to manage and avoid exceedance of the NML. Where possible, the offset distance between noisy plant items and nearby noise sensitive receivers should be as great as possible. Where possible, equipment with directional noise emissions should be oriented away from sensitive receivers. Regular compliance checks on the noise emissions of all plant and machinery used on site would identify whether noise emissions from plant items were higher than predicted. This also identifies defective silencing equipment on the items of plant. Ongoing noise monitoring during construction at sensitive receivers during critical periods to identify and assist in managing high risk noise events.

30 7 Conclusion The RLJV project Team s proposed ancillary facility at Alfred Street (Site 3) does not meet all of the ancillary facilities location criteria as required by CoA D28, therefore this assessment is being referred to the Secretary for approval prior to the establishment of the 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 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.

36 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

37 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

38 Spray-on insulation or soundproofing; Asbestos cloth and rope; Millboard; Drywall mudding compound; Pipe and Boiler lagging (i.e. hot water pipes, domestic heaters & stoves); Heat resistant fabrics; Loose fill roofing insulation (not common); Carpet underlay; Decorative paints; Brick & plaster sealants, fillers & some adhesive products, and Hail or fire damaged, or badly weathered asbestos cement products. 3 Legislation, standards and guidelines Table 3-1 details the legislation, licences, standards, planning instruments and guidelines considered during development of this plan.

39 4 Procedure WestConnex M4 Widening Major Civil Works SWMP Appendix F- Asbestos Management Strategy Page 7 of 15

40 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 Construction 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

41 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

42 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

43 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

44 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

45 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

46 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

47 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.

49 Flood Contingency Planning Detailed flood contingency planning is required to ensure human health and property impacts are avoided. The following management measures shall be implemented; 1. Weather forecasts will be monitored on a daily basis or as weather changes. This data will be used to guide work activities undertaken on-site. Forecasts shall be checked by the on-site Supervisor and discussed with the relevant engineers at the start of each day and prior to undertaking new work activities that may be affected by rainfall or adverse weather. 2. Where weather forecasts predict conditions that may pose an environmental risk, site environmental controls shall be inspected and secured to reduce erosion and sediment control impacts. 3.

Noise and vibration predictions have been undertaken, where appropriate, for the Site 3 Ancillary site construction works. The predictions indicate that some of the proposed activities are likely to exceed the construction goals causing a potentially significant impact at some locations and should therefore be managed in accordance with mitigation measures detailed within this report. I trust this information is sufficient for your requirements; however, please contact me if you require further information.

63 Rizzani Leighton Joint Venture M4 Widening Ancillary Site Facility - Site 3 Construction Noise Impact Assessment 2 November Ancillary Site 3 CNIS docx Page 2 1 Introduction 1.1 Report Objectives SLR Consulting Australia Pty Ltd (SLR) has been tasked by the Rizzani Leighton Joint Venture (RLJV) to assess the potential impacts from construction works associated with the Ancillary Site Facilities which are proposed to be undertaken as part of the M4 Widening Project. This report presents the noise impact assessment relating to the M4 Widening Project works that are planned to be undertaken at Ancillary Site 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 is: Construction Noise Interim Construction 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 Construction 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 elements of the overall activity results in the likely worst-case noise impacts. It is noted that rolling activities associated with the Hardstand works scenario are assumed to employ non-vibratory rolling plant. SLR Consulting Australia Pty Ltd

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 against the 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 Construction 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). The term RBL is described in detail in the NSW Industrial Noise Policy (EPA 2000). SLR Consulting Australia Pty Ltd

65 Rizzani Leighton Joint Venture M4 Widening Ancillary Site Facility - Site 3 Construction Noise Impact Assessment 2 November Ancillary Site 3 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, Construction 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. 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) 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. Construction 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. Predicted LAeq(15minute) noise levels at the worst-affected receivers are shown in the maps in Appendix B. Acoustic shielding provided by property boundary fencing has not been included in the construction noise prediction methodology as the effective acoustic properties of such constructions can vary significantly due to configuration and maintenance specifics. The results presented below are therefore considered conservative as boundary fencing may provide additional noise screening up to around 10 db depending on relative orientation of source and receiver.

This level of NML exceedances is typical for site clearing works using chippers within close proximity to receiver buildings. NML exceedances for the site establishment works would be concerning for surrounding residents and particular effort should be directed towards the implementation of all feasible and reasonable noise mitigation and management strategies as per the standard mitigation measures detailed in the ICNG. It is noted that high noise activities associated with the site establishment works (tree removal and hardstand) will be undertaken over a period of three days or less (refer Table 1). The construction noise impacts for these works will therefore only affect the nearby receivers for a relatively short period of time. Long-term ancillary facility operations are predicted to produce moderate worst-case NML exceedances of up to 12 db. Ancillary site worst-case NML exceedances are representative of all plant operating concurrently immediately adjacent the nearest receiver facade. In practice the noise producing plant will be located further away from the nearest sensitive receivers, resulting in lower NML exceedances of up to 9 db. 5 Discussion The noise predictions indicate that worst-case LAeq(15minute) construction noise levels of up to 90 dba are expected at the most affected residential receivers adjacent Site 3 for site establishment works. The construction noise impacts for these works are anticipated to only affect the nearby receivers for a relatively short period of time and are restricted to daytime construction hours. Long-term ancillary facility operations are predicted to produce moderate typical worst-case NML exceedances of up to 9 db at receivers located immediately adjacent the ancillary site. Particular effort should be directed towards the implementation of all feasible and reasonable noise mitigation and management strategies detailed in Section 6. Predicted LAeq(15minute) noise levels at the worst-affected receivers are shown in the maps in Appendix B. 6 Traffic Noise The ICNG does not provide specific guidance in relation to acceptable noise levels associated with construction traffic. For assessment purposes, guidance is taken from the RNP however it is noted that these are taken as noise goals only and are not mandatory. SLR Consulting Australia Pty Ltd

68 Rizzani Leighton Joint Venture M4 Widening Ancillary Site Facility - Site 3 Construction Noise Impact Assessment 2 November Ancillary Site 3 CNIS docx Page 7 One of the objectives of the RNP is to apply relevant permissible noise increase criteria to protect sensitive receivers against excessive decreases in amenity as the result of a proposal. In assessing feasible and reasonable mitigation measures, an increase of up to 2 db represents a minor impact that is considered barely perceptible to the average person. On this basis, construction traffic NMLs set at 2 db above the existing road traffic noise levels during the daytime and night-time periods are considered appropriate to identify the onset of potential noise impacts. Where the road traffic noise levels are predicted to increase by more than 2 db as a result of construction traffic, consideration would be given to applying feasible and reasonable noise mitigation measures to reduce the potential noise impacts and preserve acoustic amenity. In considering feasible and reasonable mitigation measures where the relevant noise increase is greater than 2 db, consideration would also be given to the actual noise levels associated with construction traffic and whether or not these levels comply with the following road traffic noise criteria in the RNP: 55 db LAeq(1hour) day and 50 db LAeq(1hour) night for existing local roads. 6.1 Existing and future traffic flow Project related daytime traffic flow including three (3) heavy vehicles and 1.5 light vehicles per hour is expected due to the proposed stockpile facility. The existing and estimated future local traffic flows (per hour) for the potentially affected streets are shown in Table 5. Existing traffic flows were referenced from the EIS technical paper, SLR Report R2 WestConnex - M4 Widening, Pitt Street, Parramatta to Homebush Bay Drive, Homebush, Construction and Operational Road Traffic Noise and Vibration Impact Assessment dated 23 July Project vehicles will be limited to standard daytime use only and as such no assessment of night time impacts has been conducted.

69 Rizzani Leighton Joint Venture M4 Widening Ancillary Site Facility - Site 3 Construction Noise Impact Assessment 2 November Ancillary Site 3 CNIS docx Page 8 The predicted noise increase presented in Table 6 shows that the additional traffic flow from the proposed stockpile facility will result a 0.3 dba and 14.9 dba noise increase at the nearest noise affected receivers by using Alfred Street and A Beckett Street as the main entrance respectively. It is recommended to use Alfred Street as the main entrance to the proposed stockpile facility due to the minimum noise effect to the nearest residential receivers. Whilst the inclusion of project traffic on A Beckett Street would result in a significant change in noise levels, over all noise levels would be compliant with the RNP LAeq 1hr criteria of 55 dba. However, mitigation measures and communication with the local community are required if A Beckett Street is chosen to be the main entrance to the proposed stockpile facility. 7 Mitigation Measures Based on the assessment of construction noise impacts in this report a range of noise mitigation measures have been recommended to reduce and control potential construction noise impacts. The construction noise mitigation measures are recommended, where feasible and reasonable, to minimise potential for disturbance at receivers, preserve the acoustic amenity of the surrounding environment and aim to control noise levels within the NMLs. Construction Noise : The use of temporary barriers / hording around stationary/localized items of plant (may include stockpiling areas or loading areas). Temporary barriers that break the line of sight from the receiver to the noise producing plant can typically mitigate noise levels by between 5 db and 10 db. Loading and unloading should be carried out away from sensitive receivers, as far as practicable. Work areas (stockpiling, fabrication, maintenance etc) within compounds should be located as far as practicable from nearby sensitive receivers. Avoiding noisy plant from working simultaneously in close proximity adjacent to sensitive receivers will result in reduced noise emissions and exposure. Equipment which is used intermittently is to be shut down when not in use. Where possible, the offset distance between noisy plant items and nearby noise sensitive receivers should be as great as possible. Where possible, equipment with directional noise emissions should be oriented away from sensitive receivers. Regular compliance checks on the noise emissions of all plant and machinery used on site would identify whether noise emissions from plant items were higher than predicted. This also identifies defective silencing equipment on the items of plant. Ongoing noise monitoring during construction at sensitive receivers during critical periods to identify and assist in managing high risk noise events. Reversing of equipment should be minimised so as to prevent nuisance caused by reversing alarms. Where audible reversing warnings are required, these units should be non-tonal. Where possible, schedule a respite period of one hour for every three hours of continuous construction activity, or scheduling high noise generating works to the less sensitive times of 9:00 am to 12:00 pm or 2:00 pm to 5:00 pm. 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

70 Rizzani Leighton Joint Venture M4 Widening Ancillary Site Facility - Site 3 Construction Noise Impact Assessment 2 November Ancillary Site 3 CNIS docx Page 9 Construction Traffic Trucks will not queue outside residential properties. No trucks will arrive on site or be permitted to queue near sensitive receivers outside of standard construction hours unless required by road safety considerations. Truck drivers will limit compression braking as far as practicable. Truck movements will be kept to a minimum, ie trucks will be sufficiently utilised for each trip. Truck movements will be restricted to identified haulage routes and the routes outlined in the Construction Traffic Management Plan. The contractor will provide training to all project personnel, including relevant sub-contractors on noise and vibration requirements from this plan through inductions, toolbox talks and targeted awareness training 8 Cumulative Impacts Cumulative noise impacts warrant assessment where more than one works scenario operates at the same time and in the same location such that the same receiver is impacted by noise from more than one works scenario in comparable magnitudes. The prediction of cumulative noise levels from more than one construction scenario operating close to another scenario within the proposal area is a complex matter given the number of sources and possible locations of a particular combination of construction works. In practice, it is not always possible to specify the precise location of more than one works scenario for the same 15-minute period and the assessment becomes overly conservative to calculate the cumulative impacts based on all nearby works operating on a worst-case basis at the same time. In conjunction with the operation of site 3 ancillary facility, M4 Widening construction works are likely to occur on the southern side of the M4 Motorway near Alfred Street (refer to Figure 1). Table 7 details the proposed construction works and corresponding sound power levels for works scenarios which may occur within close proximity of the compound. Table 7 Construction Scenarios Construction Scenarios Maximum LAeq Sound Power Level (likely worst case scenario) Pile/pile caps construction 107 Column and girder construction 110 Deck construction 110 Parapet installation 105 Asphalt works. 115 A construction noise assessment of M4 Widening construction works has been document in SLR report OOWH Western Zone Sept Taking into account the construction scenarios in Table 7 and a review of the predicted noise levels for M4 Widening construction works, receptors adjoining Site 3 ancillary facility would likely experience and increase of up to 3 db when works occur simultaneously. Mitigation measures which have been documented within this report (Section 7) would be required to manage these impacts. 9 Construction 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.

74 A.1 Introduction The WestConnex Delivery Authority (WDA) has contracted Rizzani Leighton Joint Venture to undertake works to widen and upgrade the M4 Motorway generally between Pitt Street, Parramatta and Homebush Bay Drive, Homebush. It is understood that the areas subject to the upgrade works are to be cleared, excepting a small drainage line to the north of Adderley Street West, which will remain unaffected by the upgrade works. Cumberland Ecology was contracted by Rizzani Leighton Joint Venture to undertake a preclearing assessment of a section of the project alignment located adjacent to Alfred Street, Granville. (hereafter referred to as the subject site ) (see Figure 1 in Appendix B) in accordance with mitigation measures detailed in the Construction Environmental Management Plan (CEMP). A.2 Methodology A.2.1 Desktop Assessment The Biodiversity Assessment report prepared by Jacobs SKM (2014) was consulted to determine threatened flora species likely to occur within the subject site. Threatened species identified in the Biodiversity Assessment for the project were targeted during surveys. The following noxious weeds, declared under the NSW Noxious Weed Act 1993 in the Holroyd, Parramatta, Auburn, Strathfield, Canada Bay and Burwood Local Government Areas (LGAs), were also identified for consideration during the field surveys (Table 1). Some of these species are also identified as Weeds of National Significance (WONS) under the National Weeds Strategy and require stricter control measures due to their invasiveness and potential for spread.

Survey methodologies are detailed below. i. Flora Surveys Targeted searches for threatened flora and noxious weeds known from the locality were performed by conducting random meander transects throughout the subject site. Where threatened species or noxious weeds were detected, pink flagging was attached to large individuals of the plant. The pink flagging tape had the feature number written on it. ii. Fauna Surveys Identification of fauna habitat features, such as hollow-bearing trees, trees with nests, decorticating bark, aquatic habitat, and piles of logs and debris, was undertaken throughout the subject site. Any fauna habitat features had their locations recorded with a hand held Global Positioning System (GPS) unit, and were marked with pink flagging tape. Flagging tape was numbered with the designated tree or feature number. CUMBERLAND ECOLOGY LET AUGUST 2015

77 A.3 Results A.3.1 Flora i. Threatened Flora No threatened flora species were identified within the subject site. ii. Weeds Lantana (Lantana Camara), Broad-leaf Privet (Ligustrum lucidum), Balloon Vine (Cardiospermum grandiflorum), Madeira Vine (Anredera cordifolia), African Olive (Olea europaea subsp. cuspidata) and Asparagus Fern (Asparagus aethiopicus) are noxious weeds found to occur within the subject site (see Photograph 1 in Appendix C). The locations of these individuals that were recorded during survey are shown in Figure 1 and identified in Table 2.

It is expected that any clearing undertaken within the subject site is undertaken in accordance with any relevant approvals. A.4.1 Threatened Flora There are no recommendations for threatened flora as no threatened species were identified within the subject site during the assessments. A.4.2 Noxious Weeds The noxious weeds (as identified in Figure 1 and Table 2) should be cleared, stockpiled, and removed from site or stockpiled securely and covered in black plastic to ensure the spread of weeds does not occur. If practical, suppression of weeds should occur through the use of bush regenerators. A.4.3 Habitat Features One small nest was identified within the subject site on 3 August Clearing of native vegetation and habitat features should be undertaken using a two-stage clearing process, whereby an area around habitat features is cleared initially, leaving the habitat features isolated. These should then be left overnight, prior to felling under an ecologist s supervision. CUMBERLAND ECOLOGY LET AUGUST 2015
