1. Introduction

1.1 Purpose and Application

This Construction Soil, Stormwater and Flooding Management Plan (CSSFMP) describes how the Laing O’Rourke team will ensure all risks associated with erosion and sediment control, surface water quality, site wastewater, potential water contamination, groundwater and flooding issues are considered and managed effectively during the design and construction stages of the Moore Park Works as part of the Managing Contractor early works for the CBD and South East Light Rail (CSELR) Project (the Project).

This CSSFMP addresses the relevant requirements of the Project Approval (EIS, Submissions Report and Minister’s Conditions of Approval (CoA)) the Project Contract (with TfNSW) and all applicable guidelines and standards.

Section 0.0 (Page 3) of this CSSFMP includes a table demonstrating the Plan’s compliance against the requirements of the CoA including CoA 66 (which requires the Plan to be prepared, consulted and approved).

1.2 Background

1.2.1 CSELR Overview

The Project incorporates the new light rail network, a 12 km route integrating major interchanges with other transport modes at Circular Quay, Wynyard, Town Hall, Central, Randwick and Kingsford, which will transform Sydney and support the city’s growing economy and population. The expanding light rail network will connect people to jobs, homes, entertainment precincts and form part of an integrated public transport solution to ease congestion and improve services.

The new light rail network will be delivered in two stages, as follows:

Stage 1 – CSELR Early Works Managing Contractor - critical and long lead enabling works being undertaken by Laing O’Rourke (appointed by Transport for NSW (TfNSW)).

Stage 2 – CSELR Main Construction Works – to be delivered under a Public–Private Partnership (PPP) contract (to be appointed by TfNSW).

1.2.2 CSELR Moore Park Works Overview

The Moore Park Works scope includes:

Moore Park Tennis Centre – Reconfiguration of the existing car park and access driveway at the Tennis Centre as well as construction of a replacement amenities block prior to demolition of the existing amenities block for the Moore Park Tennis Centre.

Tramway Oval Eastern Extension - An extension of the turfed surround of the current Tramway Oval Field by 5 metres to the east, to create provision for a subsequent relocation of the oval by the Public Private Partnership (PPP) Contractor.

Moore Park Bus Loop – Construction of a temporary bus turnaround to run event buses in both directions on the events bus loop located to the east of Tramway Oval during construction of the CSELR project.

Moore Park Construction Compound – Establishment of a construction compound to support the works within Moore Park.

Further details are provided in Section 2 of the Moore Park Works CEMP.

1.2.3 Environmental Planning Approval

The Project has been assessed by TfNSW under Part 5.1 of the Environmental Planning and Assessment Act 1979 (EP&A Act) as State Significant Infrastructure (SSI). The Project, its impacts, consultation and mitigation were documented in the following suite of documents:

SSl Application SSI 6042;




7/46

CSSFMP

CBD and South East Light Rail Project, Environmental Impact Statement, TfNSW November 2013; and

CBD and South East Light Rail Project, Submissions Report (incorporating Preferred Infrastructure Report), TfNSW March 2014.

The Minister for Planning granted Approval for the Project in the Minister’s Conditions of Approval (CoA, 4 June 2014 (ref SSI-6042)).

1.2.4 CSELR Moore Park Works Approval Pathway

In accordance with Condition of Approval (CoA) A7 of the Planning Approval, the Project is able to be constructed in stages provided that those stages are undertaken consistently with the Conditions of Approval.

Due to a key Project’s priority to commence (and therefore complete) an initial package of early works in advance of the main early works by the Managing Contractor (MC) for the Project, TfNSW has requested a Staged Approval to permit the priority works to be commenced in advance of the main MC works.

A Staging Report has been submitted to DPE which reflects the proposed first stage of MC works, referred to as the Moore Park Works. Subsequent Stages will be described and approved through subsequent submissions of the required Plans such as this CSSFMP.

1.2.5 Project-Specific Environmental Management System

The Moore Park Works Construction Environmental Management Plan (CEMP) is the head EMS document for the delivery of the Moore Park Works and this Plan is one of the suite of Aspect-Specific support Plans and Environment Procedures to the CEMP. In summary, these documents include: Moore Park Works Construction Environmental Management Plan (Moore Park Works CEMP) Moore Park Works Construction Noise and Vibration Management Plan (CoA B89 (b)) Moore Park Works Construction Traffic, Transport and Access Management Plan (CoA B89 (c)) Moore Park Works Soil, Stormwater and Flooding Management Plan (CoA B66) – this Plan Moore Park Works Construction Heritage Management Plan (CoA B89 (e)) Moore Park Works Construction Business Management Plan (CoA B89 (f)) Moore Park Works Construction Compound and Ancillary Facility Plan (CoA B88 (a)) Community Communication Strategy (CoA B90)

1.3 Objectives and Targets

Laing O’Rourke project objectives and targets related to Construction Soil, Stormwater and Flooding Management, and which are applicable to the Moore Park Works are as follows:

Minimise erosion on site through implementation and maintenance of appropriate erosion and sediment controls.

o Target - Inspections by ER, TfNSW and regulator resulting in no occurrence of significant issues/non-compliances.

Limit the disturbed area and stabilise as soon as practicable following the completion of works Prevent pollution of surface water to ensure existing water quality of surrounding surface

watercourses is maintained. o Target: no pollution incidents resulting in environmental harm or regulatory action o Target: no written warnings or Penalty Infringement Notices arising from the works

Ensure all discharges from site comply with the objectives of Section 120 of POEO Act. o Target: no non-compliances with s120 PoEO Act – i.e no incidents of “pollution”.

Prevent mud and litter from being deposited on roadways Minimise demand for, and use of, potable water for construction and maximise opportunities for

water re-use from captured stormwater, wastewater and groundwater. Design and construct works to minimise adverse increase in flood impacts to local and regional

catchments.

3. Existing Environment

3.1 Soils

3.1.1 Moore Park Works Local Conditions

The Moore Park, Kensington/Kingsford and Randwick precincts are underlain by Quaternary age unconsolidated sands known as Botany Sands. The Botany Sands comprise medium to fine grained marine sand with podsols.

ASS are known to occur in low-lying coastal floodplain areas. The ASS risk map is provided in Figure 10.4 of the EIS, indicates the overall risk of disturbing ASS in the Moore Park sections of the CSELR alignment is considered to be low and no known occurrences of ASS have previously been identified.

3.2 Contamination

3.2.1 Moore Park Works Local Contamination Risks

According to the EIS, historical land use surveys indicate that in the area of Moore Park, the key potential contamination risks are:

• bonded asbestos materials

• PAHs

Further, in accordance with MCoA B72, a Stage 2 Contamination Site Investigation report is currently underway regarding risks within the Moore Park Work. If the Stage 2 Contamination Site Investigation identifies contamination to the extent that a Remediation Action Plan (RAP) is required for the site, any specific risks and mitigation measures, beyond measures in the Moore Park Works CEMP and this Plan, are to be included in the Site Auditor endorsed RAP (CoA B72(a)).

3.3 Water Quality

3.3.1 Moore Park Works Local Water Quality Conditions

Kippax Lake is the only water course in proximity to the work and is located approximately 50m to the north of the Tramway Oval site.

During construction site water would drain to the Ponds of Centennial Parklands which form the upper catchment of the Botany wetlands. They act as a detention basin and receive stormwater runoff from surrounding catchments including Randwick. Water quality has been poor in the past and is currently improving due to recent measures put in place to improve it.

The key construction impacts on stormwater quality would be sediment mobilisation and deposition, oil and petrol from construction vehicles and accidental spills of chemicals and other hazardous construction materials.

If uncontrolled, runoff from the worksites could result in discharge of contaminants to receiving waterways, further contributing to the poor water quality in the catchments downstream.

It is also noted that run off from site (if uncontrolled and polluted) to Ponds of Centennial Parkland has potential to cause pollution of the ground water aquifer which is recharged by the ponds.

3.4 Flood Conditions

3.4.1 Moore Park Works Local Flood Conditions

Flood information related to the Moore Park site is presented in Table 3-1 (Locations 2/3 from EIS) and identifies that the area will suffer some degree of flooding following a rainfall event with an ARI of one in five

years, with some flooding along the southern section of Anzac Parade predicted to occur more frequently during a one in two year ARI event.

No data < 0.1 0.2–0.5 0.2–0.5 0.5–1.0 1.0–2.0 1.0–2.0

Note: ARI = Annual recurrence interval; PMF = probable maximum flood

Potential of localised flooding issues during construction caused by surface water entering, or falling directly onto the construction area will be mitigated by implementing site-based management measures including earthen bunds, sediment fences and stormwater inlet protection as detailed in Section 5 and Appendix C and D. With these measures in place, construction phase stormwater flows should not result in additional flow velocities or volumes off site.

Existing stormwater infrastructure will remain in place during the Moore Park construction works, minimising localised flooding potential due to construction activities. All new connections to the existing stormwater system, as part of the construction works, will be approved by an appropriately certified designer to ensure capacity of the system is acceptable. The above measures will minimise impact to the downstream drainage network.

3.5 Groundwater

3.5.1 Moore Park Works Conditions

The major aquifer system in the vicinity of Moore Park is the Botany Sands aquifer, an unconsolidated aquifer that predominantly consists of sand. Groundwater in the shallower beds is unconfined, but in the deeper layers is partially confined. Groundwater flow direction generally is from north to south, partly tending to the north-east to south-west. Potential sensitive receptors include groundwater bores, a stormwater channel on Alison Road and the Alexandra Canal. Recharge mainly occurs via rainfall infiltration. Ponds in Centennial Park receive stormwater, which recharges the aquifer. It is likely that some recharge from leaking pipes also occurs. Groundwater levels fluctuate over time in response to recharge, pumping, and (in locations where the water table is shallow), evapotranspiration. EIS summarises water table levels taken from the NSW Office of Water’s (2013) database which range between 0.5 metres and 7 metres below ground level. Groundwater within the Botany Sands is mostly low in salinity. In 2003, an embargo was implemented under section 113A of the Water Act 1912 in the northern part of the aquifer (where the alignment is located), because available water was depleted by plumes of contamination. The Moore Park Works will comprise surface/shallow excavations; additionally no groundwater was encountered during geotechnical investigations undertaken for the Moore Park Works which were based on the proposed design and construction methodology depths. Therefore works are not anticipated to encounter or impact significant groundwater, with the exception of perched shallow bodies if encountered, and volumes of groundwater to be intercepted and dewatered are expected to be minimal. The key risk associated with the works is from accidental spills or leakage from construction plant which are to be mitigated as per Section 5 of this Plan.

5. Management Measures This Section describes the overall approach and principles associated with managing and mitigating soil, stormwater and flooding risks during the Moore Park Works. Further Appendix B includes Table B1- Mitigation Measures which details specific actions and responsibilities to be implemented during the works. The management measures are based on the mitigation measures compiled from the EIS, Submissions Report (Revised Environmental Mitigation Measures or REMMs) and the Minister’s Conditions of Approval (MCoA), as well as the requirements and standards of TfNSW and Laing O’Rourke.

5.1 Key Soil, Stormwater and Flooding Management Tools

The hierarchy of management documentation used by Laing O’Rourke for the implementation of the mitigation measures on each site are as follows: 1. Construction Soil, Stormwater and Flooding Management Plan (CSSFMP) – key guidance

document from which the practical site-based management tools are developed 2. Environmental Controls Map (ECM) – plan/map based tool specific to site/work area and includes

the location of existing waterways, environmental protection measures, monitoring requirements, conditions of approval and environmentally/community sensitive areas

3. Erosion and Sedimentation Control Plans (ESCPs) - Site-specific ESCPs developed for each of the site to ensure conformance with the Blue Book and POEO Act requirements. Consisting of the initial Primary ESCP for each site prior to construction followed by Progressive ESCPs (PESCPs) to reflect changing nature of the site as works progress. The ESCPs would include the location of existing drainage infrastructure in proximity to the works and associated controls to be installed.

4. Procedures and Protocols - contain detailed measures to mitigate specific risks which are read in conjunction with the tools above, and include Clearing and Grubbing, Topsoil Stripping and Stockpiling, Installation of drainage, Dewatering and discharge of excavations

5. Drainage Design Reports –– Site Drainage System design reports will include hydraulic and flood modelling, consultation with relevant stakeholders (councils, neighbours) and mitigation measures to reduce flood risks.

5.2 Principles of Soil, Stormwater and Flooding Management

The following points have been identified as the key techniques to control water quality on the project. These points collectively fulfil the principles of sound soil conservation practice. In selecting appropriate control structures care must be taken so that their use does not exceed design limitations. Where exceedance of design limitations cannot be avoided detailed design of the structure will be required.

The key measures associated with sediment and erosion control will include:

Check the operation of all project-related sediment and erosion controls at least once per day during operational hours, to help identify potential water pollution risks

Minimising the exposure of fill and excavated material to active work fronts Ensuring stockpiles or other materials are not placed within 15m of drainage lines or water courses

where practical Retention of stabilised areas as much as practical to prevent erosion Diverting stormwater runoff around disturbed areas of the site where practical to prevent

contamination with runoff from the disturbed areas. Where this is not possible, control measures such as diversion drains will be constructed to ensure stormwater runoff does not cause additional erosive impacts

Bunded chemical storage areas will be located within the compound and will have provision for protection from rainfall and will consist of lockable containers. To avoid the cumulative effect of multiple container failure the bund will be sufficient to contain 110% of all liquid materials contained within the bund

Implementing water quality control measures prior to the commencement of construction activities




14/46

CSSFMP

Implementation of temporary and permanent erosion and sediment controls to prevent sediment from the construction site from leaving site. The specific measures are outlined below in subsequent sections of this Plan

Laing O’Rourke will monitor temperature, humidity, wind velocity and rainfall at the nearest Australian Bureau of Meteorology weather station or site compound weather station

If high rainfall events are predicted erosion and sediment controls will be inspected to ensure maintenance is not required, Inspection of controls during rainfall event will occur to ensure they are performing.

5.3 Permanent Controls

5.3.1 Vegetation

All disturbed areas are to be stabilised and or revegetated in accordance with the contractual requirements as soon as practical following final land shaping.

5.3.2 Drainage

Appropriate local stormwater and pavement drainage design will be developed for the Tennis Centre car park and the Tramway Oval for the bus turning circle at the Tramway Oval site.

5.4 Temporary Controls

Temporary controls will be documented on Erosion and Sedimentation Control Plans (ESCPs). These will be developed prior to relevant works activities commencing and based on detailed site investigations.

5.4.1 Erosion and Sediment Control Plans

Progressive Erosion and Sediment Control Plans (ESCP) will be prepared for all areas of the work site prior to the commencement of construction. The ESCPs will include landforms and flow paths, existing drainage infrastructure, ERSED controls, stockpile locations and additional actions for management of spoil in accordance with Managing Urban Stormwater: Soils and Construction Volume 1 (Landcom 2006) (the Blue Book”).

5.4.2 Batter Protection

Exposed batters of the site during earthworks represent a significant source of readily erodible material until final stabilisation is achieved. To minimise the potential for the generation of sediment laden water run-off from exposed batters during the works, geotextile fabric will be placed and secured as a temporary erosion control measure where practical.

5.4.3 Sediment Fences

Sediment fences or suitable equivalent operate by slowing the flow of runoff and enabling the coarse suspended solids to settle out and be trapped behind the control structure. Sediment fences will be utilised for stockpiles of spoil and other erodible materials, site perimeter sections and disturbed areas.

Design limitations are:

Drainage area ≤0.6 ha Maximum grade 1V:2H Maximum slope length 60m.

Particular attention must be made to the potential outlet of the sediment fence during high rainfall events and the likely point at which the fence will discharge. To ensure that the fence remains intact during high flow events and runoff discharges to the appropriate areas, a small reinforced weir may need to be constructed in the fence. This will be reviewed daily during construction. Weirs in sediment fences must outlet to stable areas.




15/46

CSSFMP

Details on location of these structures will be verified on site, and incorporated in the working Erosion and Sediment Control Plans.

5.4.4 Sandbags and Sediment Socks

Sandbags and sediment socks are utilised to create a weir or check dam in table drains to slow the runoff water velocity and enable coarse sediment to settle. They can also be used to create diversion drains or bunds walls to contain liquids, or to supplement existing sediment controls and will be placed around any existing live stormwater pits or drop inlets prior to decommissioning of the structure. Locations will be confirmed on site and included in working sediment and erosion control plans.

Check dams will be carefully constructed where required to allow runoff to exist the sediment control structure via the intended flow path. A specifically constructed low point must be incorporated into the dam to direct runoff and ensure that flow is retained within its intended path.

5.4.5 Dust Control

Water carts fitted with sprays will be used to wet down any unsealed haul roads and fill areas to minimise the amount of dust generated where required. The number and size of the water carts shall be regularly reviewed by the Site Supervisor and the Project Manager to ensure that adequate watering is taking place and dust is kept to a minimum. Care is to be exercised to limit the amount of water used to ensure run-off does not occur and leave the site.

5.4.6 Stockpiles

Temporary stockpiles shall be located more than 15m from drainage lines or water courses where practical. Sediment barriers shall be erected on the down slope side so that any sediment laden runoff from the stockpile is captured and controlled. On the upslope, berms or catch drains shall be installed, if practicable, to divert clean water away from the stockpile.

Stockpiles will be covered or stabilised when not in use to minimise erosion and dust.

5.4.7 Site Access

A stabilised access is to be utilised to reduce the tracking of sediment off-site. A street sweeper will be utilised as required during the construction phase of the project.

5.5 Operation and Maintenance of Site Controls

Construction water quality structures and sediment controls will be implemented and maintained until such times as disturbed areas have been stabilised. The Site Supervisor and Project Environmental Manager will continually inspect the site’s environmental controls during active works and when controls are required to be installed and left on site between track possessions. An inspection of the site will also be undertaken following heavy rainfall events.

The Site Supervisor and Environmental Manager will also inspect the site prior to Rostered Day Off (RDO site shut-down day) weekends or other periods of extended closure.

Permanent and temporary sediment control structures which become blocked or overloaded with sediments will be cleaned out using appropriate methods such as an excavator, backhoe or by manual means. Cleaning shall be performed prior to or when the accumulated sediment has reduced the capacity of the structure to less than 60%, based on a visual assessment.

Silt collected from cleaning temporary and permanent sediment and erosion control measures shall be mixed with dry material and incorporated into the works where deemed able. Detention basins (if used) will be de-silted when the capacity of the sediment storage zone has been reduced to less than 60%.

All temporary erosion and sediment controls will be removed and the areas rehabilitated as per the revegetation and landscaping details.

CSSFMP

5.6 Site Wastewater Controls

5.6.1 Waste Water

All site waste water will be directed to existing site sewerage facilities in compliance with the requirements of the Sydney Water Act 1994 or waste from portable toilet facilities will be managed and disposed by a licenced contractor.

5.6.2 Concrete Washout

Where washout of concrete trucks is required on site, the Laing O’Rourke Site Supervisor will locate a designated washout area a minimum of 20m away from any natural watercourses or drainage lines.

An Environmental Risk Action Plan (ERAP) relating to concrete washout has been included in the Moore Park Works CEMP. Concrete Washout areas will be set up in accordance with the intent of the NSW EPA guideline ‘Environmental Best Management Practice Guideline for Concreting Contractors’ (2002) and TfNSW Concrete Washout Guideline – 3TP-SD-112.

5.6.3 Paint Washout

Where wash out of paint is required on site, a paint washout facility will be located in a designated and signposted washout area.

5.7 Water Discharge Requirements

Water discharge and reuse on the Moore Park Works will be in accordance with the TfNSW Standard; Water Discharge and Reuse Guideline - PE-ST-146.

5.7.1 Criteria for Discharge to Water

As an Environment Protection Licence is not going to be held for the CSELR MC Works, the criteria for discharge of site water to stormwater is set by the objective of compliance with Section 120 of the POEO Act. Specifically, Laing O’Rourke would utilise ANZECC (2000) Australian and New Zealand Guidelines for Fresh and Marine Water Quality (utilising ANZECC Protection Level Criteria of 3. Highly Disturbed Systems) to determine these criteria (i.e. a breach of ANZECC Guideline represents a breach of POEO Act). The highly disturbed criteria has been adopted in the case of the Moore Park Works as suitable for the proposed discharge of site water to stormwater and based on the existing local water quality conditions (Section 3.3.1).

Any water discharged from site must be of the same quality, or better, than the “background” water quality of the receiving water bodies.

Prior to, during and after discharge, the quality of the discharge and receiving waters are to be tested and characterised to demonstrate compliance.

As a guide, before water can be discharged to any receiving waters (whether on or off site), it must as a minimum meet the following criteria:

Parameter Criterion Method Time prior to discharge

Oil and grease No visible Visual inspection < 1 hour

pH 6.5-8.5 Probe/meter 1 < 1 hour

Total Suspended Solids (TSS) < 50mg/L 2 Meter/grab sample 3 < 1 hour/< 24 hours 1 litmus paper and pool testing kits are not to be used 2 a more stringent TSS criterion may need to be adopted in certain situations 3 grab samples to be analysed at a NATA accredited laboratory




17/46

CSSFMP

The analytical results report will be assessed to confirm water quality meets applicable criteria.

If the criteria above are not met, the water will be treated and retested prior to discharge or disposed offsite.

If all criteria above are met then the water may be authorised for discharge by the PEM by completing the TfNSW Approval to Discharge or Reuse Water form; Approval to Discharge or Reuse Water - 9TP-FT-207.

As per the TfNSW Standard, discharge can use a syphon system or a pump, with a priority on delivering low energy flows to downstream drainage lines, watercourses or land. The flow from the outlet must be directed onto a non-erodible surface or material and, for discharges to waters, sufficient energy must be dissipated before the flow enters the natural watercourse to ensure no erosion shall occur.

The pump inlet must be placed so that it will not disturb or take in any sediment or sediment laden water. The discharge must be monitored throughout to ensure that the water being syphoned or pumped:

complies with the discharge criteria does not come into contact with any soil or exposed surfaces before discharging does not mix with any sediment laden/untested water at either the inlet or outlet.

Water must never be discharged or reused onsite in a manner that exceeds the capacity of sediment controls and/or generates runoff with the potential to discharge from site.

5.7.2 Discharge to Land

The objective of discharging water to land (within the site boundary) is to allow the water to infiltrate into the ground, thus avoiding direct discharge to, or pollution of, waters. Any suspended solids in the water are deposited either on the surface or retained in underlying soil layers, so the TSS criterion does not apply. However, to avoid impacts to vegetation or soil contamination pH testing and a visual inspection for oil or grease must be undertaken.

In addition to criteria for discharges to water:

No surface runoff will be generated from the discharge and there is no potential for discharged water to reach any watercourse (within or outside the site)

No erosion is caused from the discharge and appropriate erosion and sediment control are installed in accordance with the Blue Book

All discharge water can be wholly contained within the site boundary.

5.7.3 Reuse on Site

Water to be reused on site for dust suppression or other uses will not require the TSS criteria as with discharge requirements as the water will not be discharged from the Project site, however pH testing and visual inspection for oil and grease is still to be undertaken. The flowchart from TfNSW Water Discharge and Reuse Guideline Planning & Environment: Standard PE-ST-146 outlines the process for testing water and determining options for reuse, discharge or disposal.

5.8 Drainage/Flooding Design and Construction

The Moore Park construction works and the operational drainage impacts will not significantly change the site levels, drainage configuration or increase the final impermeable area and consequently is not envisaged to have a significant adverse impact on the local flood potential. Approximately 50m of the existing drainage at Tramway Oval will be replaced as part of the eastern extension of the Oval, designed and approved by an appropriately certified designer. The final design of the Moore Park Tennis Centre works, including car park reconfiguration, landscaping and construction of a new amenities building will be designed and approved by an appropriately certified designer




18/46

CSSFMP

As documented in the relevant Design Reports, designs for all Moore Park construction works includes local hydraulic and flood modelling taking into account existing stormwater system capacities, local topography, proposed additions to the stormwater system associated with the new amenities building and areas of new pavement. These reports have indicated that the proposed Moore Park works will not increase flooding potential of the local or downstream area and will have negligible impact to the existing stormwater system. Consultation has been undertaken with relevant stakeholders (CMPT, asset owners, and council) in order to ensure that flood risks are considered and mitigated. These Design Reports will meet the requirements of CoA 65 and, as required, be in compliance with the NSW Floodplain Development Manual.

5.9 Incident Management

In the case of an incident resulting in contamination of water (e.g. fuel spill) or contaminated / turbid water being discharged from the site then the incident management procedures located in Moore Park Works CEMP will be implemented.

In all cases, the situation will be assessed and if safe to proceed measures implemented to stop or slow down the released of contaminated material from the site. The Project Construction Manager and Environmental Manager will be informed and all necessary stakeholders informed as per the incident management process in the Moore Park Works CEMP.




19/46

CSSFMP

6. Soil, Stormwater and Flooding Risk Training

All site personnel shall undergo site specific induction training, which will include environmental awareness. It will also include training in the need for effective sediment and erosion control on site. Toolbox meetings will also be undertaken as and when required; covering specific environmental issues and shall include erosion and sediment control measures.

Personnel directly involved in implementing sediment and erosion control measures on site will be given specific training in the construction, operation and maintenance of the various measures to be implemented.

Personnel conducting sampling, measuring, monitoring and reporting activities are to be suitable trained or experienced in the activity. Records of all training are to be filed in accordance with the project filing system.

It is the Project Environment Manager (and Site Environmental Officers) responsibility to ensure all personnel are appropriately trained as outlined above.




20/46

CSSFMP

7. Monitoring of Controls

Site inspections and audits will be undertaken in accordance with Section 18 of the Moore Park Works CEMP, and in accordance with this Plan for soil, stormwater and flooding management during construction.

All water quality control and sediment control structures (e.g. sediment fences, drainage protection, temporary check dams/sumps) will be regularly inspected and maintained throughout the project. The Site Construction Manager is responsible for managing the installation of controls and rehabilitation of the sites in accordance with the requirements. The Project Environment Manager (and Environmental Site Officers) are responsible for monitoring the installation and maintenance of controls and providing training.

Daily inspections of controls will be made by Supervisors and maintenance will be recorded in site diaries during active site works.

The Project Environmental Manager will conduct a detailed documented inspection at least once per week during active works and after any heavy rainfall. An inspection of the site will also be undertaken prior to RDO weekends and other times where the site will be closed or inactive for an extended period. The inspections will focus on the integrity, capacity and performance of the site control measures which will include the sediment fences, temporary check dams/sumps, diversion bunds, drain protection and rehab works.

Items that require repair or action will be documented on the site environmental inspection. Items that require specific and detailed action will be recorded on the Project’s Corrective Action Register. The Superintendent will be responsible for providing appropriate resources in terms of labour, plant and equipment to enable the items to be rectified in the nominated timeframes.

If deemed necessary, additional sedimentation control measures will be implemented to ensure that water quality is maintained throughout the works. Improvement requests received from the TfNSW, Environmental Representative or other appropriate agencies shall be assessed and responded to within 24 hours if the issue is not environmentally threatening.

The following forms and check sheets shall be utilised to inspect, monitor and record erosion and sediment controls and water quality on this project and filed in accordance with the project filing system.

Stakeholder Date/Format Comment Response

1.3 Objectives and Targets:Section 1.3 of the CSSFMP indicates the objectives and targets related to Construction, Soil, Stormwater, and Flooding Management include to maximise opportunities for water re-use from captured groundwater (page 8). The Office of Water requests it is provided with details on the expected groundwater inflows and the volumes of groundwater to be dewatered and re-used as part of the Stage 1A Moore Park MC works.

Section 3.5.1 Additionally a response will be provided to NOW on e-mail

3.2.2 Moore Park Water quality Conditions:The CSSFMP notes that during construction, site water would drain to the Ponds of Centennial Parklands (see Section 3.2.2, page 12). It indicates that if uncontrolled, runoff from the worksites could result in discharge of contaminants to receiving waterways but contaminates could also enter the aquifer, as Table 3.5 indicates the Ponds of Centennial Park receive stormwater which recharges the aquifer (page 14). It is suggested Section 3.2.2 also makes reference to the potential for contaminates to enter the aquifer if runoff is uncontrolled.

Section 3.3.1

3.4.2 Moore Park Conditions:Section 3.4.2 notes the Stage 1A Moore Park works will comprise surface/shallow excavations and are not anticipated to encounter or impact significant groundwater with the exception of perched shallow bodies (page 14). It is noted in Table 3.5 that the Sydney Basin Central Aquifer is approximately 2 to 3 m below ground level within areas traversed by the CSELR alignment and water table levels of the Botany Sands Aquifer range between 0.5 m and 7 m (page 14). The Stage 1A Moore park works as outlined in Section 1.2.2 do not appear to involve significant excavation but it is suggested Section 3.4.2 is amended and it includes specific details, including: the maximum depths of excavations associated with the works, the depth of the shallow perched groundwater expected volumes of groundwater to be intercepted and dewatered.

Section 3.5.1

4. Aspects, Impacts and Risks:It is recommended an air photo and scaled map is included in the CSSFMP which shows the location of the proposed works and the location of all watercourses and drainage lines potentially affected by the works.

Section 3.3.1 Section 3.4.1 Section 5.1

Stockpiles and Concrete washout:Section 5.4.6 of the CSSFMP indicates temporary stockpiles shall be located more than 15 m from drainage lines or watercourses (page 18) and Section 5.6.2 refers to concrete washout areas on site being located a minimum of 20 m away from any natural watercourses or drainage lines (page 19). It is suggested Table B1 in Appendix B, is amended so that SSF 24 and SSF 28 specify the minimum setback distances of 20 m and 15 m respectively.

Table B1

6. Soil, Stormwater and flooding risk training:Section 6 Soil, Stormwater and flooding risk training: It is unclear who will be responsible for undertaking the training and it is suggested the CSSFMP includes this detail.

From: "Wendy Stevenson " <[email protected]> Date: 11 August 2014 2:50:29 PM AEST To: Shannon Blackmore <[email protected]> Cc: Neville Moran <[email protected]>, Nicole Jones <[email protected]>, Mark Hanemann <[email protected]> Subject: CBD and South East Light Rail (CSELR) - Moore Park Works - EPA Comments on Construction Soil, Stormwater and Flooding Management Plan

Hi Shannon The EPA has reviewed Copy No. V0.00 of the Construction Soil, Stormwater and Flooding Management Plan (the Plan) prepared for the Stage 1A Moore Park Managing Contractor (MC) Works, which was provided to the EPA via the email below on 04 August 2014. The scope of the review covered environmental protection issues within the remit of the EPA and focussed on the Plan’s identification of appropriate guidelines and procedures. The review also assumed that the Plan has been prepared by appropriately qualified personnel and that all quantitative values contained within the Plan (such as those relating to sediment fence design and water discharge criteria) have been based on appropriate guidelines or criteria. It is noted that the EPA does not approve or endorse EMPs. The EPA’s comments on the Plan are as follows:

Section 1.1 Purpose and Application: The first sentence (which refers to the scope and purpose of the Plan) should also

refer to groundwater. Section 1.3 Objectives and Targets: The fourth dot point (regarding compliance with the Protection of the Environment

Operation Act 1997) needs to be reworded. Section 120 of the Act does not contain any criteria that can be exceeded.

It is noted that any discharges to water that do not meet the ANZECC (2000)

guideline requirements may be considered to constitute a breach of section 120 of the Protection of the Environment Operation Act 1997 unless an exemption is granted by the EPA via an environment protection licence.

Section 2.3 Guidelines: This section should also list guidelines of relevance to water quality.

The following additional guidelines should also be referenced:

o Managing Urban Stormwater: Soils and Construction – Volume 2A: Installation of services (DECC 2008).

o Guidelines on the Duty to Report Contamination under the Contaminated Land Management Act 1997 (DECC 2009)

o Australian and New Zealand Guidelines for Fresh and Marine Water Quality (ANZECC 2000)

Section 3.1 Soils: This section should also identify any contamination issues and corresponding

management requirements.

Section 5.7.1 Criteria for Discharge to Water: 1st sentence - It is noted that that any discharges to water that do not meet the

ANZECC (2000) guideline requirements may be considered to constitute a breach of section 120 of the Protection of the Environment Operation Act 1997 unless an exemption is granted by the EPA via an environment protection licence.

2nd sentence - This should refer to the “background” water quality of the receiving

water bodies rather than the quality of receiving waters at the time of discharge. The water quality objectives for the receiving water bodies and relevant trigger levels/ guidelines should be determined with reference to appropriate current guidelines, including the ANZECC (2000) guidelines.

In the event that discharges to waters are to be carried out as part of the works,

water quality monitoring will be required both prior to and during construction and must be sufficient to enable identification of project impacts.

These works will form Stage 1 of the project and a Staging Report is currently being prepared in accordance with condition A7 of the Minister’s Conditions of Approval (MCoA attached) that will be submitted to the Department of Planning and Environment (DPE) shortly. Detailed design, construction and operation of the CSELR Project will be undertaken by a Public Private Partnership as the second stage of the project. The first package of works to be undertaken by Laing O’Rourke as part of Stage 1 will occur entirely within Centennial Park / Moore Park Trust (CPMPT) lands. The works, referred to as the Moore Park Works, will include:

Tramway Oval is used as a training ground for the Sydney Swans AFL team. Works on the oval are time constrained due to the fact the oval needs to be handed back to the Sydney Swans by the end of October 2014. In order for this to occur, the construction works at this location would need to be commenced by approximately the 26th August 2014. As the proposed works are limited to the extent of the CPMPT lands, DPE have agreed to TfNSW submitting CEMP and associated sub-plans for the proposed Moore Park Works in order that the above timeframes can be met. As part of this process EPA need to be consulted on the soil and water management plan and the noise and vibration management plan. It is the intention to submit these plans Monday the 4 August for your review. Could you please confirm your availability to undertake this review and if you would like us to come in and discuss the submission this week we would be happy to do so?

CBD and South East Light Rail –Construction Soil, S tormwater and Flooding Management Plan – Stage 1A Moore Park MC works

The NSW Office of Water (Office of Water) provides the following comments on the Construction Soil, Stormwater and Flooding Management Plan (CSSFMP) for the Stage 1A Moore Park MC works:

It is suggested a table is included in the CSSFMP which summarises who will be involved with implementing the plan, the tasks, roles and responsibilities; the frequency etc including:

• who will inspect/monitor/maintain the permanent and temporary sediment controls and the frequency of when will this occur and identify which position(s) this information will be reported to

• who will test the quality of any water to be discharged from the site and the receiving waters • who will undertake training; • who will remove the controls and rehabilitate disturbed areas.

1.3 Objectives and Targets: Section 1.3 of the CSSFMP indicates the objectives and targets related to Construction, Soil, Stormwater, and Flooding Management include to maximise opportunities for water re-use from captured groundwater (page 8). The Office of Water requests it is provided with details on the expected groundwater inflows and the volumes of groundwater to be dewatered and re-used as part of the Stage 1A Moore Park MC works. 3.2.2 Moore Park Water quality Conditions: The CSSFMP notes that during construction, site water would drain to the Ponds of Centennial Parklands (see Section 3.2.2, page 12). It indicates that if uncontrolled, runoff from the worksites could result in discharge of contaminants to receiving waterways but contaminates could also enter the aquifer, as Table 3.5 indicates the Ponds of Centennial Park receive stormwater which recharges the aquifer (page 14). It is suggested Section 3.2.2 also makes reference to the potential for contaminates to enter the aquifer if runoff is uncontrolled. 3.4.2 Moore Park Conditions: Section 3.4.2 notes the Stage 1A Moore Park works will comprise surface/shallow excavations and are not anticipated to encounter or impact significant groundwater with the exception of perched shallow bodies (page 14). It is noted in Table 3.5 that the Sydney Basin Central Aquifer is approximately 2 to 3 m below ground level within areas traversed by the CSELR alignment and water table levels of the Botany Sands Aquifer range between 0.5 m and 7 m (page 14). The Stage 1A Moore park works as outlined in Section 1.2.2 do not appear to involve significant excavation but it is suggested Section 3.4.2 is amended and it includes specific details, including:

• the maximum depths of excavations associated with the works, • the depth of the shallow perched groundwater • expected volumes of groundwater to be intercepted and dewatered.

4. Aspects, Impacts and Risks It is recommended an air photo and scaled map is included in the CSSFMP which shows the location of the proposed works and the location of all watercourses and drainage lines potentially affected by the works.

NSW Office of Water | Page 3 of 3

Stockpiles and Concrete washout Section 5.4.6 of the CSSFMP indicates temporary stockpiles shall be located more than 15 m from drainage lines or watercourses (page 18) and Section 5.6.2 refers to concrete washout areas on site being located a minimum of 20 m away from any natural watercourses or drainage lines (page 19). It is suggested Table B1 in Appendix B, is amended so that SSF 24 and SSF 28 specify the minimum setback distances of 20 m and 15 m respectively. 6 Soil, Stormwater and flooding risk training:

It is unclear who will be responsible for undertaking the training and it is suggested the CSSFMP includes this detail.
