MDW Environmental Services Job # E2014-017 Sampling & Analysis Plan – Cultural Limestone 1

1 INTRODUCTION

MDW Environmental Services (MDWES) has been engaged by High Manor Pty Ltd to prepare a Sampling & Analysis Plan (SAP) for Cultural Limestone at Lot 1 Military Road, Wilbinga, herein referred to as the Site.

As part of the environmental investigation, a separate SAP has been prepared to identify and

mitigate any risks associated the processing and crushing of Construction and Demolition (C&D)

waste. This specifically relates to potential the generation of dust during the movement and

crushing of stockpiled C&D material for potential respirable dust (including silica, PM2.5 & PM10

particulates and asbestos). At this stage it has to be assumed that the C&D material contains

asbestos due to the sources where the C&D was obtained.

The Site as a whole is a historical limestone quarry and limestone block manufacturing facility

(c.2006). Recently, C&D materials have been brought to Site and stockpiled. They will eventual be

crushed and used as hard stand and road base (as long as they are asbestos free). As the C&D

material may contain asbestos, it will be monitored during the movement and crushing processes.

The facility has been operational for approximately eight years. However, in July 2013, the

proponent was notified that the facility was carrying out operations that made it a “Scheduled

Premises” under the Environmental Protection Act (1987) and, consequently, needed to submit a

Works Approval Application and associated Licence application.

As part of the Works Approval and Licence Application process, this SAP has been developed to determine the nature and extent of potential contaminants associated with current Site operations. This SAP has been developed to determine the, nature and extent of potential contaminants within the C&D material. The SAP and proposed investigation has been developed in accordance with the Department of Environment Regulation (DER) - Contaminated Sites Management Series (2001 – 2010) which includes the Department of Health (DoH) The Guidance for Assessment Remediation and Management of Asbestos-Contaminated Sites in Western Australia (May 2009). In addition reference has been made to the ASC NEPM (1999) Air quality guidelines within this SAP.

1.1 Review of Existing Reports

MDWES is not aware of any previous reports for this Site. Therefore, no assessment or reference

has been made to any other reports.

MDWES presented a Preliminary Site Investigation (PSI) in October 2014 to the DER.

E2014-017-PSI-01-MW v1 – Preliminary Site Investigation (PSI) – MDWES (October 2014).

1.2 Current Classification

The Site is not currently listed by the DER under the Contaminated Sites Act 2003. However, further soil assessments for groundwater (metals and hydrocarbons), respirable dust assessment (Asbestos, PM2.5, PM10 and silica), soil assessment for hydrocarbons, together with ecological investigations are required. This is to provide an appropriate human health and environmental risk assessment, to assess suitability of the Site for ongoing operations. This SAP has been developed to assess the Asbestos component and classification for C&D waste on Site which is to be processed and utilised on site as a one off event (the ongoing Site assessment of groundwater, soils and air is covered under a separate SAP).


1.3 Background Information

A brief summary of Site information is presented below. A more comprehensive overview will be presented in the Preliminary Site Investigation report (PSI).

Table A: Brief Summary of Site Information

Site Location Lot 1, Military Road, Wilbinga, WA.

Geology The underlying geology of the Site comprises Coastal or Tamala Limestone (Davidson 1995).

Hydrogeology The Site is located above the Gnangara Mound (North), which includes a Priority 1 Perth Drinking Water Supply Area (PDWSA). The Perth Groundwater Atlas (DoW 2004b) indicates that the aquifer depth may be approximately 25m to 30 m below the Site.

Total Site Area:

The entire Lot area is Approximately 819,500 m2

(81.5 ha)

The Site and Work area of limestone quarrying and Operations:

Approximately 136,000m2

(13.5 ha) for the area of the Lot.

Title Identification Lot 1 on Diagram 44256 – Volume/Folio 1408/392 – Lot 1 Wilbinga.

Current Site Use: Limestone extraction, limestone block manufacture and construction and demolition material storage.

Proposed Site Use:

Limestone extraction and limestone block manufacture.

(the construction and demolition material is proposed to be crushed and deposited as hard stand or road base one off event).

The Site The Site slopes steeply upwards towards the south, with a variance in height of approximately 25m across the site. The site is remote and not bound by security fencing or walls. However, the site is enclosed with large-mesh stock fencing on all sides.

Neighbouring

Properties & Land use

Much of the surrounding environs consist largely of partially cleared pasture or undeveloped bush. There are no residential dwellings within the Site’s vicinity.

Site Elevation The site ranges from approximately 45 to 70 metres Australian Height Datum (AHD).

Current Ownership: High Manor Pty Ltd.

Local Council: Shire of Gingin.

1.4 Environmental Objective

The investigation designed within this SAP is to assess the impact of proposed treatment of C&D

materials by Cultural Limestone, in terms of human health (construction / workers / local residents)

and associated environmental risks. The investigation will:

Investigate the presence (or otherwise) of potential asbestos containing material (ACM) in the stockpiled construction and demolition materials pre and post crushing, prior to its use as on-Site hard stand or road base.

Assess the human risks with respect to respirable dust (asbestos, PM2.5 & PM10 particulates) that may be associated with the processing of the C&D material.

Provide meaningful and accurate results on which to base potential human health and ecological risk recommendations.

Consider the suitability of the Site for use as a Prescribed Premises, taking into account the zoning of surrounding properties.


The objective of the SAP is to outline the sampling methodologies, sample locations and laboratory analysis to be completed.

1.5 Contaminants of Potential Concern

The assessment made within this SAP is for the potential for Asbestos within the stockpiled C&D

waste on Site, which has identified the following Contaminants of Potential Concern (CoPC).

Asbestos (Potential): common asbestos such as brown, white and blue asbestos was commonly used within building materials, construction, plumbing and engineering, prior to the late 1980’s. Once airborne, asbestos fibres can cause respiratory problems and can damage lung tissue. Inhalation of asbestos fibres can cause asbestosis, lung cancer and mesothelioma. The risk of contracting these diseases increases with the number of fibres inhaled.

Particulates (PM10 and PM2.5). Long-term exposure to current ambient PM concentrations may lead to a marked reduction in life expectancy. The reduction in life expectancy is primarily due to increase cardio-pulmonary and lung cancer mortality. The smaller-sized particles - those 2.5 micrometres or less in diameter, called PM2.5 - are of greatest health concern because they can pass through the nose and throat and be absorbed deep inside the lungs.

2 PROPOSED INVESTIGATION – C&D CRUSHING

Based on the findings of the Preliminary Site Investigation (PSI), this Sample Analysis Plan (SAP) has been developed by MDWES as part of the scope of works. The following section outlines and discusses the requirements for an air monitoring program during the crushing of the C&D waste. The SAP has been written in accordance with Department of Environment Regulation (DER) guidelines (Development of Sample and Analysis Plan), Department of Health monitoring guidelines and NEPM guidelines.

2.1 Scope of Works

The following scope of works details the requirements for a particular aspect of operations on Site.

The stockpiled C&D waste (requires sampling and air monitoring)

It is proposed that the crushing will commence once approval of the SAP is granted by the DER. Current expectations are that the crushing will take place in late October 2014, for a period of 2-3 weeks (depending on loading and crushing speeds). MDWES proposes the following scope of works to achieve the environmental objectives.

2.1.1 Stockpiled Construction and Demolition Materials - Asbestos Survey

Construction and Demolition (C&D) materials are currently stockpiled on Site. Recyclables such as iron, aluminium, plastics and wood have progressively been removed from the stockpiles, leaving the concrete and rubble. The intention is to use the resultant “rubble” as a road base or hardstand on-Site. The rubble will be crushed to approximately 25mm and then utilised. No asbestos was thought to have been present in either of the two sources of C&D material (ie Wanneroo Shopping Centre and The Dome, Burwood). However, due to the potential for asbestos to be contained in the C&D material, on-Site asbestos sampling will be conducted on each of the pre and post crushed stockpiles. This is to ensure with confidence that ACM is not contained within the aggregate rubble before re-use on Site.

The investigation of the C&D stockpiles is a one-off event and assessment would continue until the C&D waste was either utilised on site or removed (depending on the identification of asbestos). In accordance with DoH Guidelines, the stockpiles will be controlled and monitored as follows:

Current Stockpiles will be kept “damp” to suppress any potential asbestos-containing material (ACM) being liberated from the stockpile.

Samples will be collected from the stockpile of construction and demolition (C&D) material, prior to crushing of the “rubble” (sample density of 8 samples per 1000m3)*, to confirm the presence or non-presence of ACM.

The C&D material will be analysed for asbestos fibre (AF) and fibrous asbestos (FA) weight for weight (w/w%) through laboratory analysis prior to crushing.

If no asbestos is detected from analysed stockpiled C&D material, then the C&D material will then be sent to be crushed to 25mm, using the on-Site crushing equipment.

Once the demolition material is crushed, further samples will be collected from the generated stockpile (Sample density 8 samples per 1000m3)**.

The resultant crushed C&D material will be analysed for asbestos fibre (AF) and fibrous asbestos (FA) weight for weight (w/w%) through laboratory analysis.

The samples will be sent to a National Association of Testing Authorities (NATA) registered laboratory.

If the crushed C&D material is found to be “asbestos-free” the demolition material will be used as road base on Site.


During the movement (disturbing) and crushing of C&D material stockpiles, an ongoing on-Site air monitoring program will be necessary to monitor levels. Initial sampling will be relatively intense, tapering off if no asbestos is detected (see sections, 2.1.2 and 3.2.4).

* If asbestos sampling returns positive identification from the stockpiled construction material (Prior to crushing) or from the crushed C&D material. The material will be removed from site to a licensed facility that accepts construction material which is asbestos impacted.

** Total sampling density from whole stockpile of 16 samples per 1000m3.

2.1.2 Air Monitoring Program – C&D Material

Air Monitoring Sampling (AMS) will be conducted during the movement and crushing of the C&D waste. This will be in accordance with DoH Guidelines and NEPM Air quality guidelines.

The on-Site asbestos air monitoring program will need to continue until all C&D materials have been crushed or removed from Site and the final stockpile of crushed C&D material is found to be “asbestos free”.

If approved for deposition, either as road base or hardstand, the on-Site asbestos air monitoring program will continue. Initial sampling will be relatively intense, tapering off if no asbestos is detected.

Dust particulates and asbestos fibres have the potential to be both a health hazard and a nuisance. They have the potential to be generated as a consequence of transportation and/or disturbance of the C&D material. Severity may be exacerbated by site characteristics associated with the area and include the uplift of finer particulates (PM10, PM2.5 and fibres). These finer particulates have the capacity to be inhaled by site personnel.

Daily air/dust monitoring will be conducted during the movement and crushing of the C&D material. The air monitoring is to assess human health risks posed to on-site workers.

Daily air/dust monitoring is to include dust particulates (PM2.5 & PM10) and asbestos.

Particulate PM2.5 & PM10 sampling will be conducted in accordance with AS/NZS3580.9.11-2008 Methods for sampling and analysis for ambient air – Determination of Suspended Particulate Matter PM10, PM2.5.

Asbestos fibre sampling will be conducted in accordance with NOHSC:3003 (2005) Guidance Note on the Membrane Filter Method for the Estimation Airborne Asbestos Fibres, 2nd Edition.

Monitoring stations will be positioned adjacent to the pre and post stockpiles and crushing area.

Laboratory sample analysis will be undertaken by a NATA accredited laboratory for asbestos analysis.


3 SAMPLING PROGRAM

3.1 Inputs Affecting Outcomes

There are a number of parameters that are considered likely to influence the outcomes of the investigation. These parameters are considered and include the following:

The potential presence of Contaminants of Potential Concern (CoPCs), asbestos and asbestos-containing-material within the construction and demolition materials on Site.

The potential for the Site to impact on Site workers.

The identification of potential receptors and the location of sensitive environments.

The assessment of exposure periods for the potential receptors of concern.

DER, WA-endorsed environmental criteria for each media.

The media identified as requiring assessment are outlined in Table B below.

Table B: Media and the Investigation Justification

Media Yes No Justification

Soil X At this point no assessment is proposed for the soils on Site.

Asbestos (C&D) X C&D material has been identified as potentially containing asbestos. Analysis of C&D waste for asbestos is included in this scope of works.

Asbestos (Air) X

C&D material has been identified as potentially containing asbestos. If C&D material is used for hardstand or road base, air monitoring for asbestos is included in this scope of works.

Silica (Air) X At this point no assessment is proposed for assessing silica within air particulates.

Dust

PM10 and PM2.5 (Air)

X C&D Crushing can generate PM10 and PM2.5 particles. PM10 and PM2.5

particles are both a nuisance and a potential health hazard to on-Site personnel.

Surface Water X Minimal potential for surface water to escape from Site.

Groundwater X At this point no assessment is proposed for the groundwater on Site.

Biota X At this point no assessment is proposed for an ecology assessment on Site.


3.2 Investigation Methodology

The investigation of the C&D material will involve two phases of soil sample analysis, during the Pre-Crushing and Post-Crushing of the C&D material. During the process of crushing, C&D material air monitoring will also be undertaken, to assess the quality of air within the work space area. 3.2.1 C&D Asbestos Survey – Soil Sampling Pre-Crushing

The potential for asbestos contamination of stockpiled construction and demolition (C&D) material

requires verification. Further information is required to ascertain the potential asbestos content of

the C&D material pre and post crushing (if any). The locations of all asbestos sampling locations

(on Site) are shown on Figure 3. Asbestos assessment field activities conducted at the Site are

summarised in Table C below.

Table C: Soil Sampling C&D Materials – Pre Crushing

Activity Details

Date of Field Activity Works to sample the C&D materials before crushing will commence on approval of SAP (potentially October 2014). It is anticipated that the initial asbestos sampling of stockpiles will take one day (Pre) and one day (Post).

Investigation A sample density 8 samples per 1000m3 will be collected randomly from the surface of

the C&D stockpile material Pre crushing. Once declared ‘asbestos free’ then the crushed can begin, once crushed the C&D waste will be further stockpiled. The encountered soil material will be logged and recorded in accordance with DER standards.

Proposed Sample Density

8 samples per 1000m3 will be taken from surface of the C&D rubble stockpile(s) pre

crushing.

Rationale for Sampling Locations

Opportune random samples will be taken over representative areas of all C&D stockpiles. The rationale behind this judgemental placement is based on taking representative samples from stockpiles to demonstrate the likelihood or otherwise of asbestos.

Sampling Method A 10L composite sample will be taken from the C&D material (fine).

This will be sieved using a 7mm screen. Oversized material will be assessed for ACM bagged and sampled if identified.

From the undersized sieved material, a soil sample will be taken by hand using clean gloves and collected in a laboratory-provided asbestos sample bag. The sample bag will be referenced, marked and recorded.

(Samples will be taken as best as possible from the concrete material).

QA / QC For Asbestos, no QA/QC sampled will be taken, as the sample cannot be quantified or qualified.

Calibration No calibration is required.

Decontamination Procedure

Clean gloves will be used at each location.

Special PPE Standard Site PPE is required on this Site (Hard Hat, high visibility clothing and steel toed boots).

However, Site Personnel undertaking the asbestos investigation will also wear a P3 half face respirator with a P2 filter for asbestos sampling.

Analysis Asbestos and Asbestos Containing Material (ACM) (FA and AF)

Laboratory Primary samples will be sent to ALS Environmental (Perth) NATA Accredited.

Sample Preservation Samples will be placed in laboratory supplied sample bags. Samples will be stored in an esky while on Site and in transit to the laboratory as a precaution.


3.2.2 C&D Asbestos Survey – Soil Sampling Post Crushing

Once verified as safe to do so (ie “asbestos-free”), the C&D stockpile(s) (rubble) will be crushed to

25mm size, using the current on-Site crushing and screening machinery (or an appropriate crusher

and screener will be hired). The crushed material will be stockpiled ready for post-crushing

sampling. This stockpiled material will again be sampled to confirm the presence or non-presence

of asbestos. Only once confirmed as ‘asbestos free’ can it be used for hardstand or as road base.

The locations of the crushed C&D material stockpiles have yet to be determined. Asbestos

assessment of the crushed C&D stockpiles conducted at the Site is summarised in Table D below.

Table D: Soil Sampling C&D Materials – Post Crushing

Activity Details

Date of Field Activity Works to sample the C&D materials will commence post-crushing, once stockpiled. It is anticipated that the asbestos sampling of stockpiles will take one day.

Investigation Environmental samples will be taken from the post-crushed C&D stockpiles.


8 samples per 1000m3 will be collected randomly from the surface of the crushed C&D

stockpile material.

Rationale for Sample locations

Opportune random samples will be taken over representative areas of all crushed C&D stockpiles. The rationale behind this judgemental placement was based on taking representative samples from stockpiles to demonstrate the likelihood or otherwise of asbestos.

Sampling Method A 10L composite sample will be taken from (each of) the crushed C&D stockpile(s).

This will be sieved using a 7mm screen. Oversized material will be assessed for ACM bagged and sampled if identified.

From the undersized sieved material, a soil sample will be taken by hand using clean gloves and collected in a laboratory-provided asbestos sample bag. The sample bag will be referenced, marked and recorded.

(Samples will be taken as best as possible from the concrete material).

QA / QC For Asbestos, no QA/QC sampled will be taken, as the sample cannot be quantified or qualified.

Calibration No calibration is required.

Decontamination Procedure

Disposable nitrile gloves will be used at each location.

Special PPE Standard Site PPE is required on this Site (Hard Hat, high visibility clothing and steel toed boots).

However, Site Personnel undertaking the asbestos investigation will also wear a P3 half face respirator with a P2 filter for asbestos.

Analysis Asbestos and Asbestos Containing Material (ACM) (FA and AF)

Laboratory Primary samples sent to ALS Environmental (Perth) NATA Accredited.

Sample Preservation Samples will be placed in laboratory supplied sample bags. Samples will be stored in an esky while on Site and in transit to the laboratory as a precaution.


3.2.3 C&D Asbestos Survey – Air Monitoring

Based on information provided regarding the source of the C&D materials, it is not expected that

asbestos will be detected in the C&D materials stockpiled on-Site. In addition, before it is used for

hardstand or road base, the crushed C&D material will have been checked for asbestos twice –

initially pre crushing and post crushed.

Only if verified as asbestos-free during the two phases of analysis, will the C&D waste be deem fit

for use as hardstand or road base. However, as a further check, for on-Site personnel, an air

monitoring program is proposed to verify that the Site remains asbestos-free over time. Ongoing

air monitoring for asbestos will be conducted during the transportation and crushing of all

stockpiled C&D waste, until declared ‘asbestos free’, or removed from site.

The locations of the air monitoring stations on Site are shown in Figure 3. Ongoing air monitoring

for asbestos conducted at the Site is summarised in Table E below.

Table E: Air Monitoring Program of C&D Materials

Activity Details

Date of Field Activity

Air monitoring for airborne asbestos fibres will commence prior to any disturbance of the C&D material stockpiles. It will continue during any crushing of C&D materials through to the deposition of C&D materials as hardstand or road base. Or until all C&D materials are removed from Site. (the length and duration of air monitoring is dependant on the crushing and processing of the C&D material).

Investigation Automated air monitoring equipment for Dust and Asbestos will positioned around the stockpiled C&D material, the crushing plant and the plant used to transport the C&D waste. Additional personal monitoring pumps will be placed site workers, working in or around the C&D crushing process area.


A total of 8 AMS will be utilised to monitor the movement and crushing of the C&D material. Additional personal pumps will be given to Site operators working ‘on the ground’. They will also wear personal monitors if working in the processing area.

Rationale for Sampling Locations

As long as the C&D material is kept damp the generation of dust and potentially asbestos will be localised to specific areas and should be negligible if suppressed properly. Sources of dust generation will be limited to the loading, unloading and crushing areas.

The AMS will be strategically located around within the following locations:

X2 AMS stations positioned next to the Pre-Crushed C&D stockpile.

X1 AMS located on the Crusher.

X1 AMS located on the excavator loading into the Crusher.

X2 AMS Stations positioned next to the Post Crushed C&D material.

X2 AMS locations to be utilised up and down gradient of the works area to monitor potential impact

An allowance for personal monitoring pumps should be allowed for site workers, working in and around the loading, crushing and stockpiling area.

Sampling Method Air Monitoring will be conducted in accordance with NOHSC:3003(2005) Guidance Note on the Membrane Filter Method for the Estimation Airborne Asbestos Fibres, 2

nd Edition. Limits

for monitoring 0.1f/ml time weighted average and 0.01f/ml for detection limits.

Sampling volume for dust (PM10 and PM2.5 will meet the NEPM criteria of 50µg/m3 over 24

hour timed average.

Sampling will run for the duration of the site daily operating hours, from before disturbance of any C&D material stockpile(s), through any crushing, through any deposition of C&D material. After deposition, it will be assumed that no asbestos is present on Site.


Activity Details

Calibration Daily flow calibrations (pre and post sampling) will be completed prior to commencing work on pumps place on site.

Sampling pumps used to complete asbestos monitoring are to be within their annual calibration.

QA/QC Daily blank filters will be sent with samples as a transport blank (Asbestos).

Daily pre and post sampling flow checks will be undertaken on all equipment.

Special PPE Standard Site PPE is required on this Site (Hard Hat, high visibility clothing and steel capped boots).

However, Site Personnel undertaking the asbestos investigation will also wear a P3 half face respirator with a P2 filter for asbestos.

Analysis Asbestos

4 AIR MONITORING EQUIPMENT

The following section provides a description and specifications of the equipment to be used as part

of the air quality monitoring program.

4.1 SKC AirCheck XR5000 Sampling Pump

The SKC AirCheck XR5000 sample pump is able to maintain a set flow rate from 5-5000ml/min.

The pump uses a patented isothermal flow sensor to measure flow directly and acts as a

secondary standard. A built in sensor compensates for changes in temperature that occur after

calibration. For the purposes of this project, the air sampling pump will be used with the Asbestos

Cassette Filters.

The XR5000 is a compact and light sampling device and therefore will be used in monitoring the

personnel working onsite. Table F summarises the instrument specifications.

4.4 Weather Monitoring Station

The weather station that will be used on site by MDWES is a WS501-UMB Compact Weather Station. The weather station monitors the following parameters:

Wind Direction and Speed: using 4 ultrasonic sensors which take cyclical measurements in all directions, Wind speed and direction is calculated from the measured run-time sound differential.

Air Temperature and Humidity: a NTC-resistor measures temperature and a capacity humidity sensor to measure humidity. To minimize the sensors being influenced by external factors such as solar radiation. Sensors are housed in a ventilated housing with radiation protection.

Air Pressure: is measured with a built in sensor (MEMS). The relative air pressure referenced to sea level is calculated using a barometric formula with the aid of local altitude, which is user-configurable on the equipment.

Compass: integrated digital compass used to check North-South adjustment of the sensor housing for wind direction measurement.

Precipitation: additional bucket balance.


5 CONCEPTUAL SITE MODEL

A Conceptual Site Model (CSM) describes the possible pathways by which exposure to potential contamination may occur. For exposure to occur, a complete pathway must exist between the source of contamination and the receptor, based on a Source-Pathway-Receptor model (SPR) (i.e. the person or ecosystem components potentially affected directly by the contamination). A risk may only exist where a plausible SPR linkage is present, and where the quantity or concentration of a contaminant is sufficient to pose harm. Under the statutory definition of "contamination", this may only strictly exist where contaminants pose a risk of harm to a receptor. Human and/or environmental risk may be defined as a function of the magnitude and severity of any adverse effects arising from contamination. Where the exposure pathway is incomplete, exposure cannot occur, leaving no risk via that pathway.

An exposure pathway will typically consist of the following elements:

A source of contamination – e.g. a hydrocarbon spill.

A release mechanism – e.g. migration in soil, leaching to water, emission to air (vapour).

Retention in the transport medium - i.e. soil, groundwater, surface water or air.

An exposure point - i.e. where a person(s) come into contact with contaminated dust or soil, or contaminated groundwater from a well or in a building overlying volatile contamination.

An exposure route - i.e. inhalation, ingestion, absorption through the skin

5.1 Contaminants of Potential Concern (CoPCs)

The Conceptual Site Model (CSM) developed during preparation of the PSI schematically assessed the interrelationships between potential and known contamination sources, migration pathways (geology and hydrogeology), exposure routes and potential receptors. Based on the CSM, site history, site visits and the DER Contaminated Sites Management Series, the following CoPCs identified in section 1.5 are summarised below.

Asbestos: It is anticipated that the C&D material on Site does not contain asbestos, however due to the source of the material, it is advised that a precautionary approach is adopted and air monitoring for asbestos is undertaken. Therefore, it must be assumed to be present and will be sampled for, during the processing of the C&D waste.

Dust (PM10 & PM2.5): There is the potential for dust from the C&D material and crushing of C&D material (particulates, asbestos and silica). Nuisance dust off-site is also possible, although the site is very remote.


5.2 Preliminary Site Risk Assessment

A Preliminary Risk Assessment (PRA) has been prepared, based on information obtained as part of the desk study. Possible risks associated with potential sources of contamination and sensitive receptors identified have been considered, following a source-pathway-receptor (SPR) approach. For the purpose of the Preliminary Risk Assessment (PSI), risk is expressed as a function of the nature of the source, the sensitivity of a receptor, and the magnitude or likelihood of any associated pathway(s) between the source and receptor. The source, pathway(s) and receptor are each rated on a ten-point scale, with the overall level of risk being expressed as a multiple of those ratings. The product of the risk assessment is assigned a level of risk on a scale (negligible to very high). The risk assessment scores and overall risk rating matrix is given in Table I (below).

5.3 Potential Sources

Possible sources of contamination have been identified or discounted and are summarised in Table J. The Site has been historically used as a limestone quarry and limestone block manufacturing facility. However, stockpiling of C&D waste on site, with potential asbestos material, requires additional assessment. There are several aspects of the current and/or historical operations which could present additional potential contaminant sources.

5.3.2 Potential Exposure Pathways

The possible exposure pathways are identified as natural and/or man-made pathways for the preferential migration of contaminants of concern in the liquid, airborne and/or gaseous state and are summarised in Table L, below. Potential contaminant migration pathways for the chemicals of concern could include:

Physical airborne asbestos fibres or dust transported by prevailing winds. Potential human exposure routes for the chemicals of concern within the expected land use scenario are developed as a risk to receptors. Potential human exposure points occur where a person(s) comes into contact with contaminated dust or soil, or contaminated groundwater. The following human contact points are presented below and are adopted in the “potential exposure pathways” Table L.

5.3.3 Conclusion

The CSM identified two potential sources of contamination from the proposed process for the C&D material. This includes dust from C&D materials (which has to be assumed to contain asbestos, until proven otherwise). Equally, minimal pathways were identified from potential migration of these potential contaminants which would be through airborne migration. The receptors identified include, but are not limited to, persons, structures and ecology. A numerical analysis has been adopted for the assessment of risk, expressed as the multiple of likelihood and severity (Source x Pathway x Receptor). The categories correspond to Table M with regards to risk levels. A summary of the numeric risk assessment is given in the following matrix.

Following this approach, it can therefore be seen that a variety of potential risks may be posed to various targets from possible 'contamination' – with the onsite workers being most at risk. This is mainly from possible asbestos in the stored construction and demolition material (especially once crushed and deposited as road base/hardstand). An overall designation of ‘MODERATE’ risk has been assigned to the Site. However, the risk assessment should be re-evaluated, based on the additional information gathered as part of the site investigation in relation to the C&D waste.


6 QUALITY ASSURANCE / QUALITY CONTROL

The following Quality Assurance/Quality Control (QA/QC) program will only be implemented to ensure the accuracy and precision of the air monitoring data obtained. A QA/QC program will not be undertaken for the asbestos investigation of stockpiles, as asbestos samples cannot be quantified or qualified. However, for air sampling, one blank filter will be sent for analysis for QA/QC purposes each day. Daily flow checks will be made “pre and post” air monitoring. QC measures the effectiveness of the procedures of the QA program.

6.1 Data Quality Objectives

The Data Quality Objective (DQO) process is used to define the type, quantity and quality of data needed to meet the objectives of the environmental assessment. The DQOs provide a systematic approach for defining the criteria that a data collection design should satisfy, including when, where and how to collect samples and the number of samples that should be collected. The DQOs were devised in accordance with the seven step process outlined in Section 5 of the Australian Standard guidelines AS-4482.1-2005 (Standards Australia 2005). The steps and their respective identified relevance for this project include:

Table N: Data Quality Objectives

Rule Decision

State the problem Asbestos may be present in C&D materials stored on-Site and silica and particulates may also present as health risks. The processing of the C&D material is required for use on site as a road-base and/or hard standing.

Identify the decision

The C&D requires classification and determination for asbestos within the soil matrix and also for air quality on site.

Identify the inputs to the decision

The inputs are based on the information gathered during site visits and the writing of the PSI.

Define the study boundaries

The boundary of the processing area has not been determined. The crusher is not adjacent to the stockpile of C&D waste. There will be some transportation required between stockpile and crushing deck.

Develop a decision rule

This investigation is to define the C&D material for reuse on site as long as its asbestos free.

Specify Performance and Acceptance Criteria

Sampling errors when the sampling program does not detect the variability of possible contamination on site and do not represent the site conditions.

Measurement errors that occur during sample collection, handling, preparation, analysis and data reduction. Ensure all samples are compliant with guidelines and comply with holding times. Soil samples are to be assessed by a NATA accredited laboratory

The Criteria used to assess the soils for asbestos will be DoH Asbestos assessment guidelines.

Optimise the design for obtaining data

Procedures for determining sample locations and collection of samples were developed to ensure optimal data will be used in the decision. In addition, in order to ensure that the results are suitable accurate and reproducible for use in the decision, a thorough quality assurance/quality control (QA/QC) program will be incorporated. This includes duplicate, triplicate samples as well as transport and rinsate blanks.


6.2 Quality Assurance

All procedures including staff selection, sampling methodologies, equipment, analysis methods and data transfer are based on:

National Environment Protection (Ambient Air Quality) Measure (2003);

Particularly, the following actions applied:

All samples will be collected by a trained and experienced Environmental Scientist.

All samples will be collected by the same person, ensuring that techniques used are consistent across the sampling program.

6.2.1 Soil Sampling Procedure

All soil samples will be subject to the following procedures:

Samples will be collected from C&D stockpiles (pre and post crushing) and analysed for asbestos,

The use of C&D material on site will only be permitted if the material is found to be “asbestos free”.

The C&D material will be analysed for asbestos fibre (AF) and fibrous asbestos (FA) weight for weight (w/w%) through laboratory analysis.

All samples will be marked in the field using permanent marker with a label showing e.g. sample location, depth, date and job number.


6.2.2 Air Sampling Procedure

All air samples will be subject to the following procedures:

AS3580.9.6-1990 and AS3580.9.7-1990 (PM10), USEPA Federal Reference Method (USEPA reference method: US Code of Federal Regulations Title 40 Part 50 Appendix L Reference Method for the Determination of Fine Particulate Matter as PM2.5 in the Atmosphere).

NOHSC:3003(2005) Guidance Note on the Membrane Filter Method for the Estimation Airborne Asbestos Fibres, 2nd Edition.

NIOSH Method 7500 – Silica, Crystalline, by XRD (filter re-deposition) (NIOSH, 2004).

All samples will be marked in the field using permanent marker with a label showing e.g. sample location, depth, date and job number.


6.3 Quality Control

To ensure the quality of the sampling method and laboratory analysis several quality control (QC) samples will be collected:

One transport blank filter will be taken every day to assess for cross contamination.


6.4 Laboratory

The laboratory to be used for primary analysis of the samples is ARL laboratory with NATA accreditation for all analyses to be undertaken (AIR). The secondary laboratory to be used is ARL Environmental, also NATA accredited. The laboratory to be used for primary analysis of the samples is ALS laboratory with NATA accreditation for all analyses to be undertaken (SOIL). The secondary laboratory to be used is ARL Environmental, also NATA accredited.


7 ASSESSMENT CRITERIA
