1 Introduction

1.1 Proposal identification Roads and Maritime Services is proposing to construct a new bridge on the Princes Highway over the Clyde River at Batemans Bay. The Batemans Bay Bridge replacement (the proposal) would remove the existing bridge and provide a new bridge with two lanes in each direction, improving traffic flow along the Princes Highway in Batemans Bay.

This report supports the environmental assessment for the proposal.

1.1.1 Proposal location and setting The proposal is located at the Princes Highway crossing of the Clyde River at Batemans Bay, generally between the Kings Highway and North Street (refer to Figure 1-1). Local roads including Clyde Street, Wharf Road and Old Punt Road would also be modified by the proposal.

The Batemans Bay Bridge is an important link for the Princes Highway. The Princes Highway is a classified State Highway (A1) and is the primary coastal route between Sydney and Melbourne. The Kings Highway, which is Canberra’s primary road connection to the NSW south coast, intersects with the Princes Highway in the north of the proposal area. The crossing over the Clyde River is also an important local connection between the commercial centre of Batemans Bay and areas north of the river such as North Batemans Bay.

On the southern side of the bridge is Bateman Bay’s main shopping and commercial area including a large supermarket and shopping mall. Key features adjacent to the proposal area on the south side of the bridge include holiday accommodation, commercial areas, river foreshore areas and facilities as well as an area mapped as a State Environmental Planning Policy 14 Coastal Wetlands (SEPP 14 wetland). On the northern side of the bridge are the suburbs of North Batemans Bay and Surfside. Other features near the proposal area include holiday accommodation, residences and commercial development.

1.1.2 Key features of the proposal Key features of the proposal include: construction of a new bridge to the west (upstream) of the existing Batemans Bay Bridge across the Clyde

River including:

− bridge approaches generally between Wharf Road on the northern side and Clyde Street on the southern side

− two traffic lanes in each direction (at least 3.5 metres wide)

− a three-metre-wide shared use path on the eastern side of the new bridge connecting the Kings Highway to North Street

− navigational clearance of about 12 metres from mean high water spring (MHWS) level

− no access to Clyde Street, which would pass under the new bridge

upgrade of the Princes Highway generally between North Street and the Kings Highway

upgrade of the Kings Highway / Princes Highway intersection

local road adjustments at Clyde Street, Wharf Road and Old Punt Road

earthworks, including cuttings and embankments and retaining walls to support the new bridge approaches

temporary ancillary facilities during construction including water quality controls, site offices, construction / demolition compounds, batching plants and stockpile sites

permanent operational water quality controls

utility relocations including optic fibre, telecommunications, electrical, water, drainage and sewerage

replacement of the T-wharf downstream of the existing bridge


removal of the existing bridge following opening of the new bridge

site rehabilitation and landscaping works.

The key features of the proposal are shown in Figure 1-1.

A number of temporary ancillary facilities and road diversions would be established for the proposal. These features would be removed and the relevant sites rehabilitated at completion of the proposal.

1.1.3 Proposal background The Batemans Bay Bridge is located on the Princes Highway around 270 kilometres south of Sydney and 150 kilometres east of Canberra. The existing bridge over the Clyde River at Batemans Bay was constructed in 1956 with a central lift span used to allow boats up to 23 metres in height to pass underneath. The bridge was constructed to replace a vehicle ferry across the Clyde River. While water traffic was originally related to the local timber and fishing industries, this has increasingly changed to recreational and commercial water traffic. The lift span is generally raised twice each day for a local tourist ferry but also for private yachts and commercial and recreational vessels. As the lift span is raised however, traffic along the Princes Highway is disrupted.

The existing bridge is structurally in poor condition, and does not conform to modern safety standards. Major structural components of the trusses are vulnerable to vehicle strike and there is evidence of significant vehicle impacts to the bridge occurring in the past. Higher Mass Limit (HML) vehicles are not permitted to use the bridge due to poor structural condition and height limitations. Issues with the central lift span have closed the bridge on numerous occasions resulting in local and regional traffic and economic impacts. The existing bridge provides a single, narrow lane in each direction, which can result in substantial congestion especially in peak holiday periods. Where there is an incident on the bridge or where the lift span has failed, the detour for highway traffic is around 350 kilometres.


Figure 1-1 Key features of the proposal


1.2 Purpose of the report This report has been prepared to support the environmental assessment for the proposal. The proposal is subject to assessment under two planning pathways, a review of environmental factors (REF) under Part 5 of Environmental Planning and Assessment Act 1979 (EP&A Act) and an environmental impact statement (EIS) under Part 4 of the EP&A Act.

The purpose of this report is to describe the proposal, to document the likely impacts of the proposal on the environment, and to detail environmental management measures to be implemented.

1.2.1 Secretary’s Environmental Assessment Requirements Part of the proposal is located within an area mapped as SEPP 14 wetlands. As such, an EIS has been prepared and approval is being sought for that part of the proposal under a Part 4 of the EP&A Act. As part of this process, Secretary’s Environmental Assessment Requirements (SEARs) have been issued, which stipulate the requirements for the EIS. The SEARs relevant to operational water quality are presented in Table 1-1. This report has been prepared in accordance with relevant water quality guidelines and the SEARs.

Table 1-1 Secretary’s environmental assessment requirements

Reference Requirement Where addressed

Soil and water quality

Detail the disturbance of soils and the associated impacts on: • receiving waterways and wetlands, in

particular the Batemans Marine Park • groundwater dependent ecosystems • surface and groundwater sources and quality • occurrence of acid sulfate soils and likely

disturbance of those soils.

Section 3 and 4 of this report Biodiversity Assessment Report Section 3 and 4 of this report Soils and Geology Assessment Report

1.2.2 Scope of Works The scope of works for this operational water quality assessment report comprised:

review legislation and policy framework

determine the existing water quality conditions within the Clyde River

undertake water quality modelling to assess contaminant loading generated from operation of the proposal

provide an assessment of the potential impacts and benefits during the operational phase of the proposal

describe management measures to be implemented.


2 Regulatory framework The following sections summarise the key legislation, policies and guidelines relevant to operational water quality aspects of the proposal.

2.1 NSW State Legislation

2.1.1 Environmental Planning and Assessment Act 1979 The EP&A Act provides the statutory basis for planning and environmental assessment in NSW. The EP&A Act provides the framework for environmental planning and development approvals, and includes provisions to ensure that the potential environmental impacts of a development are assessed and considered in the decision making process. As noted above, the REF proposal is subject to assessment under Part 5 of the EP&A Act. Part of the proposal is also required to be assessed under Part 4 of the EP&A Act due to the application of SEPP 14.

Section 79C of the EP&A Act outlines the matters that must be considered when granting development consent for the EIS proposal, including environmental impacts. These include impacts of the development on water quality.

Section 111 of the EP&A Act applies the REF proposal and requires that Roads and Maritime “examine and take into account to the fullest extent possible all matters affecting or likely to affect the environment by reason of that activity”. This includes consideration of the impacts of the REF proposal on water quality.

The SEARs stipulate the requirements for the EIS, as described in Section 1.2.1.

2.1.2 Protection of the Environment Operations Act 1997 (NSW) The Protection of the Environment Operations Act 1997 (POEO Act) regulates land, air, noise and water pollution in NSW. It also aims to provide opportunity for increased public involvement and access to information regarding environmental protection. An environment protection licence (EPL) is required for scheduled activities or scheduled development work outlined in Schedule 1 of the POEO Act. The following scheduled activities potentially apply to the proposal: road construction if it results in four or more traffic lanes (not including bicycle lanes or lanes used for

entry or exit), where the road is classified or proposed to be classified as a main road for at least three kilometres of its length in the metropolitan area, and for at least five kilometres in any other area

extractive activities - where excavation required for the proposal is greater than 30,000 tonnes

cement or lime handling – where either the daily volume is greater than 150 tonnes or annual volume is greater than 30000 tonnes. This would apply to the operation of a concrete batch plant if one is required.

The overall proposal does not meet the definition for a scheduled activity for road construction as the overall proposal would not be greater than five kilometres in length, nor would it meet the criteria for cement or lime handling.

With regards to extractive activities, it is estimated that the cut requirements for the overall proposal would be about 55,000 tonnes over a two year period. Due to the potential to meet the criteria for extractive activities, it is assumed that an EPL would be required for the proposal, however this would be determined during detailed design when cut requirements are refined.

Regardless of the need for an EPL, the proposal would still be required to comply with the provisions of the POEO Act. Section 120 of the POEO Act makes it an offence to cause water pollution.


2.1.3 Fisheries Management Act 1997 The objectives of the Fisheries Management Act 1997 (FM Act) are to conserve, develop and share the fishery resources of the State for the benefit of present and future generations. The objectives of the FM Act that are specifically relevant to water quality and the proposal include:

to conserve fish stocks and key fish habitats

to conserve threatened species, populations and ecological communities of fish and marine vegetation

to promote ecologically sustainable development, including the conservation of biological diversity

to promote viable commercial fishing and aquaculture industries.

By ensuring that the operation of proposal does not have significant impacts on water quality, the above objectives of the FM Act would be achieved.

2.1.4 Marine Estate Management Act 2014 The Clyde River is part of the Batemans Marine Park which is located on the NSW south coast between Murramarang Beach near Bawley Point in the north and the entrance to Wallaga Lake at Murunna Point in the south. The proposed bridge would be located within the “habitat protection” zone of the Batemans Marine Park. Some work for the proposal would be carried out within the “special purpose” zone.

By ensuring that the operation of proposal does not have significant impacts on water quality, the habitat of the Batemans Marine Park would be protected.

2.2 Other policies and guidelines Other relevant policies and guidelines are discussed in the following sub-sections.

2.2.1 State Environmental Planning Policy No 14 – Coastal Wetlands The aim of SEPP 14 is to ensure that the coastal wetlands are preserved and protected in the environmental and economic interests of NSW. The Mcleods Creek SEPP 14 wetland is located in and adjacent to the proposal area. By ensuring that the operation of the proposal does not have significant impacts on water quality, the Mcleods Creek SEPP 14 wetland would be protected.

2.2.2 State Environmental Planning Policy No 71 – Coastal Protection Relevant aims of State Environmental Planning Policy No 71 – Coastal Protection (SEPP 71) to water quality include:

to protect and manage the natural, cultural, recreational and economic attributes of the New South Wales coast

to protect and preserve the marine environment of New South Wales

to manage the coastal zone in accordance with the principles of ecologically sustainable development (within the meaning of section 6 (2) of the Protection of the Environment Administration Act 1991).

Clause 16 of the policy requires that a consent authority must not grant consent to a development application to carry out development on land to which this Policy applies if the consent authority is of the opinion that the development will, or is likely to, discharge untreated stormwater into the sea, a beach, or an estuary, a

https://www.legislation.nsw.gov.au/#/view/act/1991/60


coastal lake, a coastal creek or other similar body of water, or onto a rock platform. This relevant for the EIS proposal which requires development consent from Eurobodalla Shire Council.

As the REF proposal would be development without consent, SEPP 71 would not apply to this part of the proposal.

2.2.3 Australian and New Zealand Guidelines for Fresh and Marine Water Quality

The Australian and New Zealand Environment Conservation Council (ANZECC) published the revised Australian and New Zealand guidelines for fresh and marine water quality in 2000 (ANZECC 2000 Guidelines).

The ANZECC 2000 Guidelines provide government and the community - especially regulators, industry, consultants, community groups and catchment and water managers - with a framework for conserving ambient water quality in our rivers, lakes, estuaries and marine waters.

The guidelines form the central technical reference of the National Water Quality Management Strategy, which the federal and all state and territory governments have adopted for managing water quality.

The guidelines establish environmental values (including human uses) for different types of waterways and then provide trigger values and a methodology to ensure that the water quality of the waterway can support these values.

2.2.4 NSW Water Quality and River Flow Objectives, 2000 (2007) – Clyde River and Jervis Bay

The NSW water quality objectives (http://www.environment.nsw.gov.au/ieo/) are the agreed environmental values and long-term goals for NSW's surface waters. They set out:

the community's values and uses for our rivers, creeks, estuaries and lakes (ie healthy aquatic life, water suitable for recreational activities like swimming and boating, and drinking water)

a range of water quality indicators to help assess whether the current condition of waterways supports those values and uses.

The objectives are consistent with the agreed national framework for assessing water quality set out in the ANZECC 2000 Guidelines. These guidelines provide an agreed framework to assess water quality in terms of whether the water is suitable for a range of environmental values (including human uses).

The water quality objectives provide environmental values for NSW waters and the ANZECC 2000 Guidelines provide the technical guidance to assess the water quality needed to protect those values.

The Batemans Bay area falls within the category of waterways that are “waterways affected by urban development” (see http://www.environment.nsw.gov.au/ieo/Clyde/report-02.htm#P182_17766) these are streams within urban areas that are frequently substantially modified and carry poor quality stormwater. The process of developing the water quality objectives for the Clyde River identified several major issues that could need progressive action to achieve healthy and viable Clyde River and Jervis Bay catchments. Major issues identified relevant to the proposal were the need to:

protect the estuarine environments from adverse impacts on water quality, including the effects of drainage from acid sulfate soils. This was considered a major goal in protecting the local oyster-farming, fishing and tourism industries

improve controls on stormwater from urban areas. Greater use of filtration and tighter controls on littering were mentioned as possible solutions

http://www.environment.nsw.gov.au/ieo/


protect rivers in the catchment that have high conservation value. As a guide, such rivers should not be allowed to further degrade in water quality or flow regime, and may require restoration where they have poor water quality, a changed flow regime and habitat loss or degradation

overcome the effects of erosion and sedimentation from roads and road-building

protect wetland areas and clear the obstruction to fish passage in areas where this is a problem

respect Aboriginal spiritual and cultural values associated with rivers, creeks, wetlands and lakes; and traditional Aboriginal management roles in, and uses for, these areas-including as a source of traditional foods that are safe to eat.

2.2.5 Water sensitive urban design guideline The Water sensitive urban design guideline (Roads and Maritime 2017) describes the application of water sensitive urban design principles and techniques which are appropriate to the construction and operation of the NSW transport network. This guideline has been used to identify and design water quality measures for the proposal as well as identifying load reduction targets for specific water quality parameters.


3 Existing environment

3.1 Catchment overview The catchment for the Clyde River is 1,720 km2 with an estuary area comprising about 17 km2. Land use within the catchment is primarily forest (95.7%) with some rural (3.3%) and urban land use (0.5%)1. The proposal is located in an area affected by urban development (Figure 3-1).

The proposal area that impacts the catchment is limited to the bridge deck itself and the associated roadways.

1 Clyde River Estuary – Water Quality Report Card 2014-2015, Eurobodalla Shire Council


3.2 Sensitive environmental features The sensitive environmental features that may be affected by operational water quality impacts associated with the proposal include:

the Mcleods Creek SEPP 14 wetland is located in and adjacent to the proposal area, near the southern approach to the new bridge. Other SEPP 14 wetlands are located further upstream beyond Budd Island. Mangrove and wetland vegetation are also located on Budd Island

oyster leases are located about 500 metres upstream of the proposal between the mainland and the southern side of Budd Island. Further oyster leases are located along the Clyde River upstream from Budd Island

seagrass beds are located throughout the Clyde River estuary including within and adjacent to the proposal area

several threatened and migratory species of birds including the Pied Oystercatcher, Sooty Oystercatcher, Little Lorikeet and White Bellied Sea-eagle are known to occur within and near the proposal area

the Clyde River is classified as highly sensitive fish habitat because of the presence of SEPP 14 wetlands and extensive seagrass beds and is known habitat for the threatened Australian Grayling (Prototroctes maraena)

the Clyde River through the proposal area also forms part of the Batemans Marine Park.

3.3 Existing bridge drainage The existing bridge drainage comprises of road grates which discharge any runoff directly into the Clyde River. Runoff on the southern approach of the bridge (adjacent to the SEPP 14 wetlands area) is currently collected, piped and discharged directly to the Mcleods Creek SEPP 14 wetlands. On the northern approach of the existing bridge, runoff is partially collected, piped and discharged directly into the Clyde River. No treatment measures are incorporated into the existing local stormwater system.

Key pollutant loads in stormwater from the existing bridge and approaches were modelled using MUSIC (Ewater, Version 6), an urban stormwater improvement conceptualisation software package. The pollutant loads from the modelled area are provided in Table 3-1.

Table 3-1 Key pollutant loads in stormwater from the existing bridge and approaches

Measurement Annual load

Flow 11.9 ML/yr

Total suspended solids 4150 kg/yr Total phosphorus 7 kg/yr Total nitrogen 28.7 kg/yr

Gross pollutants 312 kg/yr

3.4 Existing water quality The NSW water quality objectives for the Clyde River are generally based upon the ANZECC 2000 Guidelines (Table 3-2). The water quality objectives state that reducing diffuse pollutant loads during rainfall and runoff periods should be a key focus for improving water quality. The water quality objectives also state the importance of managing longer term impacts, such as sedimentation and polluted sediments.

Water quality monitoring data is available for several locations along the Clyde River from the Office of Environment and Heritage (OEH) and Eurobodalla Shire Council.

Eurobodalla Shire Council has undertaken monthly monitoring at three locations relatively close to the proposal area (sites CLY400, CLY401 and CLY403). Table 3-3, Table 3-4 and Table 3-5 provide a summary of water quality data at those sites with their indicative locations identified on Figure 1 (Appendix A). Sites CLY403 and CLY400 are immediately up and downstream of the proposed bridge, respectively. Site CLY401 is around 4.5 kilometres upstream of the proposal area at the mouth of Waterfall Creek.

Water quality at these three locations is relatively consistent with the exception of conductivity which varies significantly along the length of the river due to the mixing of fresh and marine waters. The mean of most water quality parameters demonstrate that water quality is generally good within the Clyde River and complies with relevant water quality objectives where available. However, the minimum and maximum values show that water quality can deteriorate and be relatively poor for some sampling events. For most parameters there were specific sampling events where the water quality objectives were not met. This is expected to be the result of rainfall and runoff from the surrounding catchment before the sampling event.

The majority of data points monitored by OEH are located upstream of the confluence of the Buckenbowra River. Appendix A (Figure 1) identifies the three OEH monitoring points closest to the proposal area, namely locations 79, 80 and 82. These sites are about 1200 metres, 600 metres and 4400 metres upstream of the existing bridge, respectively. Only one round of water quality monitoring was undertaken at these locations and is summarised in Table 3-6. The OEH water quality results were similar to those measured by Eurobodalla Shire Council and apart from dissolved oxygen saturation, complied with the relevant water quality objectives.

A single round of dry weather surface water monitoring was undertaken at 11 selected locations within the Clyde River in July 2017. These locations are identified on Figure 1 in Appendix A. Samples were collected and analysed for a range of contaminants for the purpose of identifying baseline water quality conditions. Analytical laboratory certificates are provided in Appendix B. General water quality parameters (such as pH, conductivity and dissolved oxygen) were also measured and the data is provided in Appendix C.

Contaminant concentrations were largely below the laboratory detection limits except for some total iron and arsenic concentrations which were just above laboratory detection limits. Where contaminant concentrations are below the laboratory detections limits they complied with water quality objectives. All locations reported detectable iron concentrations with the highest reported at SW3 (170 µg/L) which is located about 1100 metres upstream of the existing bridge. SW2, located adjacent to Budd Island, also reported an iron concentration of 53 µg/L with the remainder of locations generally lower and consistent.


The origin of the elevated iron concentrations is unknown, however it may be from human activities or natural sources (eg groundwater). In water, iron is generally present as dissolved ferric iron (Fe(III)), ferrous iron (Fe(II)) or as suspended iron hydroxides. As ferrous iron was not detected (ie at <50 µg/L) and the pH measured was too high for ferric iron to be present, it is likely iron hydroxides were present. Regardless, ANZECC 2000 Guidelines (Table 8.3.2) states that typical background iron concentrations range between 0.76 µg/L and 67 µg/L within estuarine waters2. The iron concentrations reported also remain below the recreational ANZECC 2000 guideline value of 300 µg/L.

The one-off monitoring program also assessed receiving water nutrient concentrations (Table 3-7). The limit of detection for the phosphorus analysis was too high to allow assessment of results against the water quality objectives, however total phosphorus concentrations were below the limit of detection. For total nitrogen, most sites had concentrations below the relevant water quality objective apart from two sites which recorded total nitrogen concentrations of 400 ug/L and 600 ug/L.

Table 3-7 Summary of nutrient data from eleven sampling locations in dry weather

Analysis Units Range in values Water quality objective (ANZECC 2000 Guidelines)

Total Nitrogen µg/L 200 to 600 <300

Total Phosphorus mg/L <50 to <1000 <25

Overall, the monitoring data suggests that water quality in the Clyde River is generally good and complies with the NSW water quality objectives for the Clyde River (ANZECC 2000 Guidelines). However, there is a lack of wet weather nutrient and contaminant data and given this is the period when stormwater discharge would occur, further wet weather data would be required to better characterise water quality in the Clyde River.

4 Proposal water quality measures

4.1 Stormwater treatment Stormwater runoff from the new bridge and approaches would be captured and treated prior to discharge. The relevant guidelines for stormwater quality treatment design targets for the proposal are:

Water sensitive urban design guideline (WSUD guideline) (Roads and Maritime 2017a)

stormwater treatment guidelines from Eurobodalla Shire Council’s Infrastructure Design Standard (V01 undated).

These guidelines specify a target reduction in loads for key pollutants and also contain hydrological targets (Table 4-1). The WSUD guideline (Roads and Maritime 2017a) and Eurobodalla Shire Council stormwater treatment guidelines (undated) are similar in scope and load reduction targets.

Table 4-1 Guideline stormwater quality treatment design targets

Pollutant / Parameter WSUD guideline objective (Roads and Maritime 2017a)

Infrastructure Design Standard V01 stormwater treatment guidelines (Eurobodalla Shire Council, undated)

Total suspended solids 85% retention of the annual average load 80% retention of the typical urban annual load

Total nitrogen 45% retention of the annual average load 45% retention of the typical urban annual load

Total phosphorus 65% retention of the annual average load 45% retention of the typical urban annual load

Flow management Maintain the 1.5 year ARI peak discharge to pre-development magnitude.

Discharges for an average 1.5 year ARI are to be maintained at pre-development levels

Litter No objective specified 70% retention of the typical urban annual load

The proposal would be located in an area containing sensitive environmental features including the Batemans Marine Park, oyster leases, seagrass beds, SEPP 14 wetlands and habitat for threatened fish and migratory birds. Consequently, a higher level of water quality protection is warranted.

The WSUD guideline (Roads and Maritime 2017a) provides the most appropriate stormwater quality treatment targets for the proposal. These targets would be adopted as the proposal water quality targets (Table 4-2). While the WSUD guidelines doesn’t specify a treatment objective for litter, generally all stormwater treatment measures would capture a high level of litter and a greater than 70 percent capture rates would be typical.

Table 4-2 Proposal stormwater quality treatment design targets

Pollutant / Parameter Proposal stormwater quality treatment design target

Total suspended solids 85% retention of the annual average load

Total nitrogen 45% retention of the annual average load

Total phosphorus 65% retention of the annual average load

Flow management Maintain the 1.5 year ARI peak discharge to pre-development magnitude.


4.2 Spill containment Spill containment would be provided for the new bridge and approaches to ensure that spills of fuel or other hazardous from major traffic incidents are captured before entering the Clyde River. Generally spill containment volumes are based upon the type and size of typical loads of hazardous substances transported by vehicles using a proposed road or bridge – and assume the complete loss of load. A minimum of 20,000 litres of spill containment would be provided for the proposal, however further assessment of the appropriate spill containment volume would be carried out as part of the detailed design.


5 Impact assessment The key potential operational water quality impacts of the proposal would be:

discharge of stormwater runoff from the new bridge and approaches into the Clyde River and Mcleods Creek SEPP 14 wetland. Stormwater runoff from the proposal may contain a range of pollutants including heavy metals, hydrocarbons, particulates, gross pollutants and nutrients. These pollutants would accumulate on the bridge and road surfaces from passing traffic, atmospheric deposition and wind deposition.

large spills of hazardous substances from traffic incidents on the bridge and approaches involving vehicles transporting hazardous substances (eg fuel tankers). If the spilt hazardous substance entered the Clyde River or SEPP 14 wetland it could have significant environmental impacts.

5.1 Discharge of stormwater runoff The proposal would include new drainage systems for the new bridge and its approaches, which would enable stormwater runoff from the proposal to be captured and treated before discharge into the Clyde River or associated sensitive aquatic environments. The WSUD guideline (Roads and Maritime 2017a) identifies a range of potential treatment options for stormwater from roads and bridges including:

vegetated swales

bioretention swales

sediment basins

bioretention basins

constructed wetlands

ponds/wet basins

gross pollutant traps

porous and permeable pavements

exfiltration systems.

Generally, a number of treatment options would be included in design of the stormwater systems to meet treatment objectives as one option alone is unlikely to achieve the required outcomes. The selection of specific treatment options depend upon a number of factors including:

sensitivity of the adjacent environment – for a pristine environment or drinking water catchment, there would be higher need to ensure that water leaving the project is of a high quality compared to a degraded area where any improvement from the project would be of marginal value to the greater environment

effective imperviousness – an understanding of the amount of change to the imperviousness of a project area compared to what is currently present

space – the amount of physical space available may be a limiting factor

environmental constraints – whether there are other environmental issues, such as the presence of national parks or threatened species or ecological communities, which may be regarded as being of a higher level of importance for a project to resolve or determine the amount of available space

landform – overall topography of the land through which the project passes

geology – the type of geology and soil types of the site will help to ascertain which water sensitive urban design elements may be best suited for implementation

the nature and scale of the project – a project’s inherent scope may determine the amount that could be achieved by incorporating water sensitive urban design


safety – an understanding of the safety issues that may be present when incorporating water sensitive urban design should be made. This would include for both asset user and maintenance personnel

maintainability – the ability and capacity of the asset owner to maintain the water sensitive urban design element

cost – whether the whole-of-life cost (capital as well as operational cost) of incorporating water sensitive urban design into the project is regarded as being sufficiently worthy of inclusion

legislative or policy obligation – any applicable Local, State or Federal planning or legislative instruments, or any internal or external requirements such as the Infrastructure Sustainability Council of Australia Rating Tool.

The location, type and suitability of stormwater treatments options for the proposal would be determined during detailed design. The location of stormwater discharge points and the volume of treated stormwater directed to each discharge point would require consideration during detailed design to ensure no increase in pollutant loads to SEPP 14 wetlands. Stormwater treatment options would be developed in conjunction with spill containment requirements.

The inclusion of a stormwater treatment system to meet the proposal stormwater quality treatment design targets improve the quality of stormwater entering receiving waters, as the existing bridge and approaches do not have a stormwater treatment system. This would be particularly evident in wet weather, during and after stormwater runoff events.

5.2 Large spills of hazardous substances Potentially hazardous substances that are may be transported on the new bridge and approaches include petroleum products, liquid petroleum gas, corrosive materials (acids and alkalis) and other toxic materials. The risk associated with a spill of dangerous goods from a traffic incident on the proposal is determined by the likelihood of an incident occurring and the consequences of such an incident.

The likelihood of a spill incident to occur on the new bridge and approaches would be low because:

the proposal would reduce the risk of crashes as there would be two wider traffic lanes in each direction and the design of the proposal would include current safety requirements (eg improved traffic barriers, lighting and signage). The proposal would also eliminate the need for traffic to stop to allow the bridge to open. Stopped traffic is a common cause of traffic incidents

the low proportion of dangerous goods vehicles travelling through the proposal area. Heavy vehicle traffic is considered to be relatively low (about 10 per cent of traffic volume). Based on monitoring undertaken on similar highways (Connell Wagner 2004) less than one per cent of heavy vehicles would be transporting dangerous goods

there are stringent legislative controls on the transport of dangerous goods including the Australian Code for the Transport of Dangerous Goods by Road and Rail (National Transport Network 2015).

The consequence of a spill incident may is considered to be relatively minor due to:

the design of drainage system would allow sections to be isolated in the case of a spill. Potential spills not able to be contained on the road surface and drainage system would generally drain towards spill containment systems which would provide for a minimum volume of 20,000 litres. Spill containment would be provided on both sides of the Clyde River

the proximity of the proposal to various emergency services should also result in a short response time and therefore improve the ability to contain and manage spills.


5.3 Summary of impacts and benefits The impacts and benefits of the proposal are summarised in Table 5-1.

Table 5-1 Summary of impacts and benefits

Item Current Proposed Impact or Benefit

Stormwater runoff

Currently stormwater is collected off the existing bridge and is directly discharged into the river

Stormwater runoff would be collected from the new bridge and treated before directing it into Council’s existing stormwater system.

Benefit

Stormwater runoff

Stormwater on the northern approach is untreated before discharge into the Clyde River

Stormwater collected from the northern approach would be treated and then discharged into Council’s existing stormwater system.

Benefit

Contaminant loads

The existing bridge is closed periodically to allow the central lift span to be opened. During this time, traffic is idle and the potential for contaminants to leak from vehicles is increased.

Vehicles would no longer need to stop on the bridge or approaches and this would reduce the contaminant load on the road surface.

Benefit

Spill events The existing bridge does not provide any storage for spill events and would discharge any spills directly into the river if no emergency response was implemented to contain the spill.

The proposal would collect spills from the bridge and direct them to spill containment.

Benefit


6 Conclusions and management measures The operational water quality impacts of the proposal, including on the identified sensitive environmental features within and near the proposal area, would be minimal and lower than existing impacts based on the implementation of a stormwater treatment system and spill containment.

Management measures are detailed in Table 6-1.

Table 6-1 Management measures for operational water quality

Aspect Mitigation measure Responsibility Timing

Water quality monitoring

A water quality monitoring program would be developed and implemented during construction in accordance with Roads and Maritime Guideline for Construction Water Quality Monitoring (Roads and Maritime, 2003).

Contractor Pre-construction

Construction

Contamination of surface water

All fuels, chemicals, and liquids will be stored at least 40 metres away from waterways (including existing stormwater drainage system) and will be stored in an sealed bunded area within the ancillary facility. On barges, fuels, chemicals and liquids will be stored within a bunded area.

Contractor Construction

The refuelling and maintenance of land-based plant and equipment will be undertaken in a designated sealed bunded area at ancillary facilities, where possible. Refuelling of marine based plant and vessels will be undertaken in a suitably bunded area (through use of silt curtain or booms)to minimise risk of spills.


Vehicle wash downs and concrete washouts will be carried out within designated sealed bunded areas at ancillary facilities, or carried out off-site.


Regular visual water quality checks (include for turbid plumes and hydrocarbon spills or slicks) will be carried out when working in or near the waterway.


Accidental spill A site specific emergency spill plan will be developed, and include spill management measures in accordance with the Roads and Maritime Code of Practice for Water Management (RTA, 1999) and relevant EPA guidelines. The plan would address measures to be implemented in the event of a spill, including initial response and containment, notification of emergency services and relevant authorities (including Roads and Maritime and EPA).

Contractor Pre-construction

Construction

Accidental spill Emergency spill kit would be kept on site at all times. Spill kits will be located at all ancillary facilities and main construction work areas, including barges. All staff would be made aware of the location of the spill kit and trained in its use


Stormwater runoff

Operational water quality treatment and quantity will be identified during detailed design in consideration of the Roads and Maritime Water Sensitive Urban Design Guidelines (2017), impacts to SEPP 14 wetlands and the capacity of Council’s stormwater systems.

Contractor Detailed design

Spill containment Operational spill containment of a minimum of 20,000 litres will be provided to ensure that spills on the new bridge and approaches can be captured before reaching sensitive environments.

Methodology Summary

Soil samples are extracted with methanol and spiked into water prior to analysing by purge and trap GC-MS.

Water samples are analysed directly by purge and trap GC-MS. F1 = (C6-C10)-BTEX as per NEPM B1

Guideline on Investigation Levels for Soil and Groundwater.

Org-013 Water samples are analysed directly by purge and trap GC-MS.

Org-003 Soil samples are extracted with Dichloromethane/Acetone and waters with Dichloromethane and analysed by

GC-FID.

F2 = (>C10-C16)-Naphthalene as per NEPM B1 Guideline on Investigation Levels for Soil and Groundwater

(HSLs Tables 1A (3, 4)). Note Naphthalene is determined from the VOC analysis.

Metals-022 Determination of various metals by ICP-MS.

Metals-021 Determination of Mercury by Cold Vapour AAS.

Inorg-055/062 Total Nitrogen - Calculation sum of TKN and oxidised Nitrogen.

Inorg-062 TKN - determined colourimetrically based on APHA latest edition 4500 Norg. Alternatively, TKN can be derived

from calculation (Total N - NOx).

Inorg-055 Nitrate - determined colourimetrically. Soils are analysed following a water extraction.

Inorg-019 Suspended Solids - determined gravimetricially by filtration of the sample. The samples are dried at 104+/-5°C.

Inorg-076 Ferrous Iron is determined colourimetrically by discrete analyser.

Inorg-055 Nitrite - determined colourimetrically based on APHA latest edition NO2- B. Soils are analysed following a

water extraction.

Inorg-060 Phosphate determined colourimetrically based on EPA365.1 and APHA latest edition 4500 P E. Soils are

analysed following a water extraction.

Metals-020 Determination of various metals by ICP-AES.

Quality Control Definitions

Blank: This is the component of the analytical signal which is not derived from the sample but from reagents, glassware etc, can be determined by processing solvents and reagents in exactly the same manner as for samples.

Duplicate : This is the complete duplicate analysis of a sample from the process batch. If possible, the sample selected should be one where the analyte concentration is easily measurable.

Matrix Spike : A portion of the sample is spiked with a known concentration of target analyte. The purpose of the matrix spike is to monitor the performance of the analytical method used and to determine whether matrix interferences exist.

LCS (Laboratory Control Sample) : This comprises either a standard reference material or a control matrix (such as a blank sand or water) fortified with analytes representative of the analyte class. It is simply a check sample.

Surrogate Spike: Surrogates are known additions to each sample, blank, matrix spike and LCS in a batch, of compounds which are similar to the analyte of interest, however are not expected to be found in real samples.

Laboratory Acceptance Criteria

Duplicate sample and matrix spike recoveries may not be reported on smaller jobs, however, were analysed at a frequency to meet or exceed NEPM requirements. All samples are tested in batches of 20. The duplicate sample RPD and matrix spike recoveries for the batch were within the laboratory acceptance criteria. Filters, swabs, wipes, tubes and badges will not have duplicate data as the whole sample is generally extracted during sample extraction. Spikes for Physical and Aggregate Tests are not applicable. For VOCs in water samples, three vials are required for duplicate or spike analysis.

Duplicates: <5xPQL - any RPD is acceptable; >5xPQL - 0-50% RPD is acceptable. Matrix Spikes, LCS and Surrogate recoveries: Generally 70-130% for inorganics/metals; 60-140% for organics (+/-50% surrogates) and 10-140% for labile SVOCs (including labile surrogates), ultra trace organics and speciated phenols is acceptable.

In circumstances where no duplicate and/or sample spike has been reported at 1 in 10 and/or 1 in 20 samples respectively, the sample volume submitted was insufficient in order to satisfy laboratory QA/QC protocols.

When samples are received where certain analytes are outside of recommended technical holding times (THTs), the analysis has proceeded. Where analytes are on the verge of breaching THTs, every effort will be made to analyse within the THT or as soon as practicable.

Where sampling dates are not provided, Envirolab are not in a position to comment on the validity of the analysis where recommended technical holding times may have been breached.

Measurement Uncertainty estimates are available for most tests upon request.
