Dear Stephen

Hazardous Materials Survey – Southern Toll Booths, Sydney Harbour Bridge

1. Introduction

Parsons Brinckerhoff was engaged by the NSW Roads and Maritime Services to undertake a hazardous

materials survey of the southern toll booths on the Sydney Harbour Bridge, Sydney NSW. The site

investigation was conducted by Parsons Brinckerhoff on 6 August 2012. For the purpose of this survey, the

term hazardous material is limited to the following:

asbestos containing materials (ACMs)

synthetic mineral fibres (SMF) material

class of compounds known as polychlorinated biphenyls (PCBs)

lead based paint systems

lead contaminated dust

zinc chromate based paint systems

The purpose of the survey was to identify the presence of the hazardous materials and to prepare a

hazardous materials register and removal control plan for the buildings/areas surveyed prior to the

commencement of the demolition works or any other works that may disturb them.

2106784A LT_6065 2/5

2. Methodology

2.1 General

The identification of hazardous materials involves a combination of visual inspection of the accessible

areas of the building / structure and the collection of representative samples of the suspect materials for the

purpose of analytical confirmation. Where identical suspect materials are detected at different locations,

visual confirmation only may have been made rather than additional sample collection.

2.2 Identification of Material

2.2.1 Asbestos Containing Materials

Representative samples of materials suspected of containing asbestos were collected and analysed in our

in house NATA Accredited Laboratory. The identification of asbestos fibres is based on using Polarised

Light Microscopy supplemented with Dispersion Staining techniques. The asbestos samples were collected

for analysis where safety of personnel would not be compromised.

2.2.2 Lead-Based Paint Systems & Lead Contaminated Dust

Representative samples of paint systems were taken from the building to determine percentage lead

content. Australian Standard, AS 4361.2-1998 “Guide to Lead Paint Management, Part 2: Residential and

Commercial Buildings” defines lead paint - a paint film or component coat of a paint system in which the

lead content (calculated as lead metal) is in excess of 1.0 per cent by weight of the dry film as determined

by laboratory testing.

Paint systems samples were forwarded to Envirolab Services Pty Ltd, an external NATA accredited

laboratory for analysis. The samples were tested for lead by using a method involving the digestion of the

paint flakes with HNO3 and analysis by ICP-MS. Results are expressed in percentage weight/weight

(%w/w).

Dust samples were collected from the ceiling space and forwarded to Envirolab Services Pty Ltd, an

external NATA accredited laboratory for analysis. Dust samples were analysed for lead content and results

expressed in mg/kg (ppm).

2.2.3 Zinc Chromate Based Paint Systems

Representative samples of paint systems were taken from the building to determine percentage zinc and

chromate content.

Paint systems samples were forwarded to Envirolab Services Pty Ltd, an external NATA accredited

laboratory for analysis. The samples were tested for zinc and chromate by using a method involving the

digestion of the paint flakes with HNO3 and analysis by ICP-MS. Results are expressed in percentage

weight/weight (%w/w).

Dust samples were collected from the ceiling space and forwarded to Envirolab Services Pty Ltd, an

external NATA accredited laboratory for analysis.

2.2.4 Polychlorinated Biphenyls (PCBs)

Representative examples of each major type of fluorescent light were examined to determine which lights

are fitted with PCB containing ballast capacitors. The details of the brand, model of each capacitor and

capacity were recorded and checked against with the ANZECC database of known PCB capacitors

and PCB free capacitors.

2106784A LT_6065 3/5

The Australian and New Zealand Environment Conservation Council “Polychlorinated Biphenyls

Management Plan, November 1996” outlines the National Strategy for the management of PCB’s.

PCB concentration PCB waste classification

<2 mg/kg PCB free.

2 mg/kg - <50 mg/kg Non-Scheduled PCB material or waste.

>50 mg/kg Scheduled PCB material or waste.

>100,000 mg/kg (10%) Concentrated PCB material

3. Restrictions/Inaccessible Areas

No access was possible within toll booths 7-18 and 20 due to keys not being made available at the time of

survey. Only limited access was available within the overhead canopy due to access points not available.

No subsurface investigation was undertaken.

4. Survey findings

This section of the report summarises the findings of the hazardous materials types identified and their

general locations. All findings are presented in Appendix A: Hazardous Materials Register.

4.1 Asbestos containing materials

4.2 Lead based paint systems and lead dust

No paint systems were found to contain greater than 1% w/w lead at the time of the inspection, as such the

paint systems tested shall not be classified as lead containing. The amount of dust present within the

overhead canopy spaces along with the toll booth tested was found to be low. Following analysis of the

dust, the risk associated with the lead content of the dust would be negligible.

2106784A LT_6065 4/5

4.3 Zinc chromate based paint systems

Paint samples tested for zinc chromate provided results below the limit of detection for chromate. As such

no zinc chromate paint has been identified during this inspection.

4.4 Synthetic mineral fibre (SMF)

No synthetic mineral fibre containing materials were identified were identified at the time of the inspection.

5. Asbestos removal control plan

5.1 General

Parsons Brinckerhoff has provided the following recommendations as a guide for the safe removal of

the identified asbestos containing materials in accordance with the requirements of SafeWork

Australia How to Safely Remove Asbestos, Code of Practice 2011.

All persons engaged in asbestos removal work should wear appropriate PPE including respiratory

protective equipment (RPE) conforming with the requirements of AS/NZS1716-2003 Respiratory

Protective Devices’ and AS/NZS 1715:2009 Selection, Use and Maintenance of Respiratory Protective

Devices. Protective disposable coveralls must be chosen that provide particle-tight protection (Type 5)

and limited splash-tight protection (Type 6). Disposable coveralls should not have external pockets or

Velcro fastenings.

All work should be carried out in accordance with SafeWork Australia How to Safely Remove

Asbestos, Code of Practice 2011 and the NSW WHS Regulation 2011 made under NSW WHS Act

2011. Handling and disposal of asbestos waste material should be carried out in accordance with

NSW DECCW Waste Classification Guidelines: Classifying Waste (April 2008) revised 2009.

All fibre air monitoring shall be carried out by an licenced asbestos assessor with NATA accreditation such

as Parsons Brinckerhoff in accordance with National Occupational Health and Safety Commission

(NOHSC), Guidance Note on the Membrane Filter Method for Estimating Airborne Asbestos Fibres

[NOHSC:3003(2005)], NOHSC, Australia.

Personal decontamination must be undertaken each time workers leave the asbestos work area and

at the completion of the asbestos removal work. Personal decontamination should be undertaken

within the nominated decontamination area. The extent of decontamination required is dependent

upon the type of asbestos being removed. If friable asbestos is being removed then a three stage

wet decontamination unit shall be required. If it is noted that non-friable ACM is being removed this

may be undertaken in a nominated dry decontamination area. Refer to SafeWork Australia How to

Safely Remove Asbestos, Code of Practice 2011 and NSW WHS Regulation 2011 made under the

NSW WHS Act 2011 for personal decontamination methods.

A clearance inspection of the work area shall be undertaken at the completion of the works by an

licenced asbestos assessor such as Parsons Brinckerhoff in accordance with SafeWork Australia How

to Safely Remove Asbestos, Code of Practice 2011.

2106784A LT_6065 5/5

5.2 Removal of asbestos cement wall linings and cladding from toll booths

The approximate extent of the asbestos cement wall linings and cladding within the toll booths is

180m2.

All asbestos removal, transport and disposal must be performed in accordance with NSW legislative

requirements.

A site specific non-friable (bonded) asbestos removal permit from WorkCover will be required by the

licensed asbestos removal contractor prior to the commencement of works.

The asbestos work area and the asbestos removal site should be clearly defined and access restricted

to prevent unauthorised personnel entering that area. Potential entry points to the asbestos work area

should be signposted or labelled in accordance with AS1319-1994 Safety Signs for the Occupational

Environment.

The work area is to be enclosed with a 200 µm thick polythene enclosure. Prior to erecting of

enclosure all non-fixed furniture, equipment and miscellaneous goods should be removed from room.

All fixtures, fittings, windows, doors and drains inside the work area shall be appropriately sealed with

200 µm thick polythene to prevent cross-contamination.

Asbestos cement sheeting should be removed with minimal breakage and wrapped with 200 µm thick

polythene and placed in bins lined with 200 µm thick polythene. Any fragments generated during the

removal should be placed within a 200 µm thick polythene bag which is no longer than 1200 mm and

no wider than 900 mm wide. All nails, screws and fasteners associated with the AC sheeting must be

removed and disposed of as asbestos contaminated waste. All timber or metal battens and polythene

sheeting must be decontaminated following removal of sheeting with the use of an HEPA vacuum

cleaner.

Following satisfactory clearance inspection by the occupational hygiene consultant and/or licenced

asbestos assessor and if deemed necessary, PVA solution should be sprayed to timber or metal

battens and polythene prior to its removal from work area and disposal.

undertaken with other asbestos removal works. If the removal of the backing board is to be

undertaken as a separate job to the remaining asbestos removal no permit will be required as the

extent is less than 10m2.




Environment.


enclosure all non-fixed furniture, equipment and miscellaneous goods adjacent to the backing board

should be removed from the area. All fixtures, fittings, windows, doors and drains adjacent to the

backing board shall be appropriately sealed with 200 µm thick polythene to prevent cross-

contamination.

All electrics should be disconnected and isolated by a certified electrician prior to the work

commencing.

Asbestos backing board should be unbolted from the wall and wrapped with 200 µm thick polythene

and placed in bins lined with 200 µm thick polythene.

Any fragments generated during the removal should be placed within a 200 µm thick polythene bag

which is no longer than 1200 mm and no wider than 900 mm wide. All nails, screws and fasteners

associated with the board and casing must be removed and disposed of as asbestos contaminated

waste. All timber or metal battens and polythene sheeting must be decontaminated following removal

of sheeting with the use of an HEPA vacuum cleaner.




5.5 Removal of asbestos putty from toll booth windows

If the toll booths are to be demolished and there is no need to retain the windows, Parsons

Brinckerhoff recommends that the window frame along with the glass and asbestos putty be disposed

of as asbestos waste. This shall ultimately save on labour costs and time to decontaminate both the

frame and glass window panes.

Additional PPE should be utilised when removing the windows including cut resistant gloves and

safety glasses/face shield.

2106784A LT_6065 7/5

The window frames should be removed whole and are to be wrapped with 200 µm thick polythene and

placed in bins lined with 200 µm thick polythene.

Any debris generated during the removal should be placed within a 200 µm thick polythene bag which

is no longer than 1200 mm and no wider than 900 mm wide. The removal area should be

decontaminated with the use of a HEPA type vacuum and wet wiping.




5.6 Removal of asbestos mastic from concrete barricades

The extent of the asbestos mastic to the barricades is unknown however it has been noted that two

types of mastic are present. The white has been noted as containing asbestos while the black as

non-asbestos.


requirements.






Environment.

Polythene sheeting drop sheets are to be placed on the ground surface adjacent to the barricades.

Following the set-up of the work area, the barricades are to be pulled apart using lifting tools. The

mastic should be removed with the use of a hammer and chisel while shadow vacuuming with the use

of a HEPA type vacuum at all times.

The mastic removed is to be placed within 200 µm thick polythene bag which is no longer than

1200 mm and no wider than 900 mm wide. The surrounding area adjacent to the barricade is to be

decontaminated of all dust and debris with the use of a HEPA type vacuum cleaner. The concrete

barriers are then to be wet wiped and a visual clearance inspection of the removal area and barriers

shall be undertaken by a occupational hygiene consultant.

5.7 Waste disposal

All asbestos containing materials removed must be either wrapped and sealed within 200 µm thick

polythene or placed within 200 µm polythene bag which is no longer than 1200 mm and no wider then

900mm wide.

Bins or tip trucks should be utilised during the removal process and placed in the car park area

between the signal box and the park.

The bins/trucks must be lined with 200 µm thick polythene prior to being filled with the wrapped

asbestos waste. The bins must be sealed (covered with 200 µm thick polythene) at the end of each

shift and prior to removal off site.

When bins are ready to be moved from the work area they must be sealed and inspected by the

occupational hygiene consultant and/or licenced asbestos assessor to ensure they are sealed

correctly prior to movement to the waste disposal facility.

2106784A LT_6065 8/5

5.8 Air monitoring and clearance procedures

In all cases an occupational hygiene consultant who may also be a licenced asbestos assessor for

friable removal or a competent person for non-friable removal with NATA accreditation from a

company such as Parsons Brinckerhoff will be required on site to carry out perimeter, personal and

clearance air monitoring and inspections. The hygienist will be required to carry out a full visual

inspection of the work area prior to the commencement of any hazardous materials removal works to

ensure containment measures are satisfactory.

During all asbestos removal works ‘work in progress’ air monitoring should be undertaken surrounding

the work area, decontamination areas and waste transit route.

Following the completion of the hazardous materials removal works the occupational hygiene

consultant will be required to undertake a thorough visual inspection of the work area and transit route.

If removal works are not to the satisfaction of the occupational hygiene consultant, removal contractors

will be required to re-enter the work area and rectify any issues arising from the inspection.

If removal works are to the satisfaction of the occupational hygiene consultant, the removal contractor

will be allowed to apply PVA solution to the enclosure if deemed necessary.

Only following satisfactory clearance inspection and air monitoring where required, will removal works

be deemed as completed.

A final inspection by the occupational hygiene consultant of the work site will be required following

removal of enclosure and equipment to ensure no debris or dust remains onsite.

5.9 Decontamination

Personal decontamination must be undertaken each time workers leave the asbestos work area and

at the completion of the asbestos removal work. Personal decontamination should be done within the

asbestos work area where re-contamination cannot occur. Refer to SafeWork Australia How to Safely

Remove Asbestos, Code of Practice 2011 and the NSW WHS Regulation 2011 made under NSW

WHS Act 2011 for personal decontamination methods

For non-friable (bonded) asbestos removal works a dry decontamination area is to be set up at the

entry point of the asbestos work area. This will include a sheet of 200 micron thick polythene weighed

down with sandbags being laid on the floor with a bucket of water and a bag of rags.

When leaving the work area all site personnel must make their way to the nominated dry

decontamination area, remove their coveralls and clean their masks and boots using the wet rags.

Respirator must remain on during decontamination and must only be removed on completion of

decontamination.

All equipment that is to leave the work area must also be decontaminated in the dry decontamination

area with the use of wet rags.

Any equipment that cannot be decontaminated completely such as HEPA vacuum cleaners and

brushes must be placed and sealed in 200µm polythene bags prior to removal from site.

Once the decontamination process is complete contaminated rags and coveralls must be disposed of

in 200µm polythene bags.

At completion of works all asbestos related materials including polythene, coveralls, geo-fabric and

rags must be double wrapped and sealed for disposal as asbestos contaminated waste.

2106784A LT_6065 9/5

5.10 PCB Containing Capacitors

A presumption has been made that the light fittings are fitted with PCB containing capacitors. If this

presumption is found to be accurate, Parson Brinckerhoff recommends that the light fittings be removed as

detailed below.

5.10.1 General

All persons engaged in PCB removal work should wear appropriate PPE including respiratory

protective equipment (RPE) conforming with the requirements of AS/NZS1716-2003 Respiratory

Protective Devices’ and AS/NZS 1715:2009 Selection, Use and Maintenance of Respiratory Protective

Devices. Disposable coveralls that provide particle-tight protection (Type 5) and limited splash-tight

protection (Type 6) should be utilised such as “Tyvex” coveralls.

Personal decontamination must be undertaken each time workers leave the PCB work area and at the

completion of the PCB removal work. Personal decontamination should be done within the PCB work

area where re-contamination cannot occur. Refer to the ANZECC Identification of PCB Containing

Capacitors (1997) and the NSW WHS Regulation 2011 made under NSW WHS Act 2011 for personal

decontamination methods.

All work should be carried out in accordance with the ANZECC Identification of PCB Containing

Capacitors (1997) and the NSW WHS Regulation 2011 made under NSW WHS Act 2011. Handling

and disposal of PCB waste material should be carried out in accordance with NSW DECCW Waste

Classification Guidelines: Classifying Waste (April 2008).

A clearance inspection of the work area shall be undertaken at the completion of the works by an

approved occupational hygiene consultant such as Parsons Brinckerhoff.

5.10.2 Removal of PCB containing capacitors

Care should be taken to avoid spillage or leakage of PCBs. The following precautions should be taken:

The electrician should wear the following PPE:

Disposable gloves made of materials that are resistant to PCBs such as Viton, polyethylene,

polyvinyl alcohol (PVA), polytetrafluoroethylene (PTFE), butyl rubber, nitrile rubber or neoprene

rubber. Do not use PVC or latex gloves. Mid-arm gauntlets may be required.

Disposable coveralls that provide particle-tight protection (Type 5) and limited splash-tight

protection (Type 6) e.g..Tyvek.

A full face shield should be worn as eye protection.

P2 respirator if light fittings are found to be fixed to flaking lead paint or any asbestos or

suspected asbestos containing material.

Licensed electrician is to disconnect electricity from light fitting, unscrew fitting and pass to licensed

removal contractor and hygienist. Licensed contractor and hygienist to be fitted with PPE.

The capacitor is to be checked for leaks.

If found to have leaked whole unit is to be double wrapped in 200 µm thick polythene sheeting.

If no leaking is evident, the capacitor is to be removed and doubled bagged in 200µm thick polythene

bags.

The following markings are to be placed on both sides of the bags:

2106784A LT_6065 10/5

"ENVIRONMENTAL CONTAMINANT – CLASS 6.1 (A). CAUTION - CONTAINS

POLYCHLORINATED BIPHENYL (PCB) – A TOXIC ENVIRONMENTAL CONTAMINANT."

All workers wash their hands thoroughly in warm soapy water before eating, drinking, smoking or

using toilet facilities.

Waste is to be placed within sealable metal containers. This container must be clearly marked with

details above, maintained in a good condition (no visible signs of damage or corrosion). The container

should be partially filled with absorbent material in case of any leakage.

The container is to be disposed of at a facility licensed to accept PCB waste.

6. Legislative requirements

Hazardous Materials remediation works must be undertaken in accordance with the following legislative

requirements:

NSW Work Health and Safety Act 2011.

<: Less than >: Greater than LCS: Laboratory Control Sample

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 batched of 20. The duplicate sample RPD and matrix

spike recoveries for the batch were within the laboratory acceptance criteria.

Duplicates: <5xPQL - any RPD is acceptable; >5xPQL - 0-50% RPD is acceptable.

Matrix Spikes and LCS: Generally 70-130% for inorganics/metals; 60-140% for organics and 10-140% for SVOC and

speciated phenols is acceptable.

Statement of Limitations

Limitations of a Hazardous Materials inspection

Scope of Services

This hazardous materials inspection report (“the report”) has been prepared in accordance with the scope

of services set out in the contract, or as otherwise agreed, between the Client and PB (“scope of

services”). In some circumstances the scope of services may have been limited by a range of factors

such as time, budget, access and/or site disturbance constraints.

Reliance on Data

In preparing the report, PB has relied upon data, surveys, analyses, designs, plans and other information

provided by the Client and other individuals and organisations, most of which are referred to in the report

(“the data”). Except as otherwise stated in the report, PB has not verified the accuracy or completeness

of the data. To the extent that the statements, opinions, facts, information, conclusions and/or

recommendations in the report (“conclusions”) are based in whole or part on the data, those conclusions

are contingent upon the accuracy and completeness of the data. PB will not be liable in relation to

incorrect conclusions should any data, information or condition be incorrect or have been concealed,

withheld, misrepresented or otherwise not fully disclosed to PB.

No Inspection Can Be Guaranteed to Locate All Hazardous Materials

In practice it is generally impossible to locate all hazardous materials in the course of an inspection.

This is because of factors such as:

The need to avoid damage, such as when attempting to inspect behind wall panels or under

carpets.

Minimising inconvenience when premises or plant are in use whilst an inspection is being

conducted.

The availability of building/plant construction plans. There is no instrument which can detect

hazardous materials.

The presence of hazardous materials must be determined visually, as there is no single, cost effective

instrument currently available for the purpose. Usually an inspector will take samples of suspect

materials and have them analysed in a laboratory. Thus, any restrictions on the amount of sampling will

reduce confidence in the hazardous materials inspection findings. The consequence of this is that

hazardous materials which cannot be seen will not be found.

Hazardous Materials are Commonplace

From the early 1900s until the early 1970s, asbestos was widely used in industry. The use of asbestos

cement sheets in roof pipes and wall cladding was particularly widespread, as was the use of “limpet”

asbestos fibre insulation in steel framed high-rise buildings. Asbestos was also used for applications

such as insulation of pipes and high temperature electricity cables, in plastics, in PVC floor tiles, for

reinforcement in cements, putties and mastic and in gaskets and friction materials.

Whilst major uses of hazardous materials were sometimes recorded on engineering drawings, there are

few records of the ad hoc use of hazardous materials and products. To give examples from the building

industry, plumbers frequently used asbestos fibre in caulking compounds and builders often used

Asbestos Cement sheeting as packing under floorboards.

In short, asbestos could be almost anywhere in a building or plant constructed before the 1980s.

Reliance on a Hazardous Materials Inspection

The client must not rely upon an inspection or report as indicating that a site or building is “hazardous

materials free”. All that the report can be relied upon to show is that no hazardous materials were found

(or that only such hazardous materials were found as was reported to have been found) in the course of

the inspection. The findings of the report must be considered together with the specific scope and

limitations of the type of inspection undertaken.

Report for Benefit of Client

The report has been prepared for the benefit of the Client and no other party. PB assumes no

responsibility and will not be liable to any other person or organisation for or in relation to any matter dealt

with or conclusions expressed in the report, or for any loss or damage suffered by any other person or

organisation arising from matters dealt with or conclusions expressed in the report (including without

limitation matters arising from any negligent act or omission of PB or for any loss or damage suffered by

any other party relying upon the matters dealt with or conclusions expressed in the report). Other parties

should not rely upon the report or the accuracy or completeness of any conclusions and should make

their own enquiries and obtain independent advice in relation to such matters.

For the purposes of this limitations statement, “conclusions” include statements, opinions, facts,

information, conclusions and/or recommendations in the report.
