(4) The lease holder shall, as and when directed by the Minister, cooperate with the Director-General to conduct and facilitate review of the AEMR involving other government agencies and the local council.

This Condition of Authority is addressed in Section 10.

1.1 OBJECTIVES AND SCOPE The primary objective of this DMP is to establish a dust management strategy for the Project that complies with Consent Conditions by providing: • a summary of relevant issues;

• air quality safeguards and procedures for dealing with dust emissions;

• details on how and when the mine operation is to be modified to minimise the potential for dust emissions; and

• dust monitoring locations and measures to continue baseline monitoring.


HAL-02-07/1/15/00685106.DOC/29/09/03 5

As assessed in the Cowal Gold Project Environmental Impact Statement (EIS) (North Limited, 1998) atmospheric dust is the predicted dominant component of air emissions from the Project. Other minor air quality emissions could potentially include exhaust fumes from mobile equipment, blasting fumes and evaporative emissions from processing facilities (Pavel Zib and Associates, 1997). As the EIS air quality assessment of the Project found these other emissions were not environmentally significant, this DMP provides safeguards, controls and management measures relating to dust emissions (both dust deposition and total suspended particulates [TSP]). This approach for the DMP has been agreed by the NSW Environment Protection Authority (EPA) (EPA, pers. comm., 5 June 2003). The DMP is structured as follows: Section 1: Outlines the objectives of the plan and details relevant consent conditions.

Section 2: Identifies relevant air quality criteria that apply to the Project.

Section 3: Outlines baseline air quality monitoring.

Section 4: Identifies potential dust generation sources for which management measures are proposed.

Section 5: Details air quality safeguards and control measures.

Section 6: Presents procedures for modifications to mining operations to minimise dust emissions.

Section 7: Outlines the air quality monitoring programme.

Section 8: Presents stakeholder consultation and notification requirements.

Section 9: Details complaint resolution and property acquisition requirements.

Section 10: Outlines reporting requirements for dust related issues. In accordance with consent condition requirements, EPA and the National Parks and Wildlife Service (NPWS) have been consulted during the preparation of this management plan. The DMP will be prepared to the satisfaction of the Director-General of the Department of Infrastructure, Planning and Natural Resources (DIPNR).

2 AIR QUALITY CRITERIA As set out in Section 1.1, relevant air quality criteria derived from the consent conditions and consultation with the EPA relate to dust deposition and TSP. Other emissions to air arising from the Project are not considered to be environmentally significant. The consent conditions require the management, monitoring and reporting of dust emissions from the Project. Dust is a generic term used to describe fine particles that are suspended in the atmosphere (Environment Australia, 1998). Consent Condition 8.3(b) requires monitoring of both dust deposition rates and concentration of TSP (Section 1). These can be defined as follows (Environment Australia, 1998): • dust deposition (deposited matter) – this term describes any particulate matter that falls out

from suspension in the atmosphere. This measurement is usually expressed in units of mass per area per time (eg. grams per square metre per month - g/m2/month); and

• TSP - the nominal size of this fraction has particles with a diameter up to 50 microns (micrometres or μm). This enables determinations of dust concentrations in units of mass (usually micrograms) per cubic metre (μg/m3).


HAL-02-07/1/15/00685106.DOC/29/09/03 6

Further detail on applicable criteria for these two aspects of air quality is provided below. Dust Deposition Table 1 details the EPA criteria for deposited dust which seek to limit total annual average levels to 4 grams per square metre per month (g/m2/month) and project related increases to 2 g/m2/month.

3.1.2 TSP No baseline monitoring of TSP was undertaken at Lake Cowal prior to the granting of development consent. Given the consistently low recorded levels of dust deposition, the concentrations of TSP are expected to be correspondingly low (Pavel Zib and Associates, 1997). Background mean annual TSP concentrations of 30 micrograms per cubic metre (μg/m3) were adopted for use in the Project EIS (North Limited, 1998).

3.2 CONTINUATION OF BASELINE MONITORING

3.2.1 Dust Deposition Dust deposition monitoring has been conducted at seven sites (Figure 3) since 1999 in a continuation of the baseline monitoring undertaken prior to the issued development consent (Section 3.1.1). In addition to the three baseline sites (51, 52 and 54), monitoring has also been conducted at the general monitoring sites of Lakeside, McLintocks, Site I5 and the Site Office (Figure 3). Continuation of baseline monitoring is further discussed in Section 7.2.

3.2.2 TSP No monitoring of TSP has occurred to date since the granting of development consent as TSP monitoring was not a component of the baseline monitoring programme. The commencement of TSP monitoring is discussed in Section 7.3.

4 DUST GENERATION SOURCES The air quality assessment conducted for the EIS (Pavel Zib and Associates, 1997) concluded that the Project would result in only minor exceedances of the dust deposition and TSP criteria outside of the Project Mining Lease Application (MLA) area. The exceedances that were identified were restricted to small areas adjoining the MLA area. No non-Company owned residences were predicted to exceed the relevant EPA criteria. Potential dust emission sources from mining operations include (Pavel Zib and Associates, 1997): • areas disturbed by construction activities;

• areas disturbed by mining activities, including waste emplacement areas and other portions of the mine site exposed to wind;

• waste rock handling and stockpiling activities (including loading and unloading, spreading and shaping of waste);

• movement of vehicles on unsealed roads for general mining activities;

• topsoil stripping and stockpiling;

• drilling and blasting; and

• crushing, screening, transport and preparation of ore.

In addition, farming activities could potentially also contribute to local and regional dust levels (Pavel Zib and Associates, 1997).

5 DUST SUPPRESSION AND CONTROL

5.1 AIR QUALITY SAFEGUARDS The Project air quality safeguards and control methods will minimise dust emissions from all sources identified in Section 4 (other than farming activities). These sources can be categorised as follows: (i) construction activities;

(ii) exposed areas (via wind erosion); and

(iii) general mining activities. Barrick will manage dust emissions proactively in a manner that minimises potential air quality impacts in accordance with development consent conditions for the Project. The air quality safeguards and control methods to minimise dust emissions that are detailed in this section have been prepared in consultation with the EPA (EPA, pers. comm., 5 June 2003). Tables 4, 5 and 6 list the air quality safeguards and control methods to minimise sources of construction, exposed area and general mining generated dust, respectively.

Table 4

Safeguards and Control Methods for Construction Generated Dust Sources

Source Control Methods

Disturbed Surfaces • Disturbed surfaces will be watered using water trucks or other methods to suppress dust.

• Areas for soil stripping will be minimised to reduce the area of exposed ground at any one time.

Access Roads • Access roads will be watered (using water trucks or other methods) and regularly maintained.

• Routes will be clearly marked.

• Obsolete roads will be ripped and revegetated.

• The speed of vehicles travelling on unsealed surfaces will be restricted.

Soil Stripping • Access tracks used for soil stripping during the loading and unloading cycle will be watered.

• Soil stripping will be limited to areas required for mining operations. After: North Limited (1998)


HAL-02-07/1/15/00685106.DOC/29/09/03 11

Table 5 Safeguards and Control Methods for Exposed Area Dust Sources


General Areas Disturbed by Mining

• Areas for soil stripping will be minimised to reduce the area of exposed ground at any one time.

• Exposed areas will be reshaped, topsoiled and revegetated as soon as practicable in accordance with DMR requirements (DMR, 2002), to minimise the generation of wind erosion dust.

Waste Emplacement Areas

• Exposed active work areas on waste emplacement surfaces will be watered to suppress dust where practicable. Progressive rehabilitation (ie. reshaping, topsoil placement and revegetation) of waste emplacement areas will continue throughout the Project in accordance with DMR requirements (DMR, 2002).

Soil Stockpiles • Long term soil stockpiles will be revegetated with a cover crop.

Material Handling and Stockpiles

• Prevention of truck overloading to reduce spillage during ore loading/unloading and hauling.

• The coarse ore stockpile will be protected by a hood to prevent wind erosion of its surface.

• All conveyors will incorporate wind covers as necessary.

• The surface of all stockpiles will be sufficiently treated to minimise dust emissions. Such treatment may include application of a dust suppressant, regular dust suppression watering or establishment of vegetation on longer term stockpiles (eg. the low grade ore stockpile).

After: North Limited (1998)

Table 6 Safeguards and Control Methods for Mining Generated Dust Sources


Haul Road • All roads and trafficked areas will be watered (using water trucks or other methods) and regularly maintained (using graders) to minimise the generation of dust.

• Routes will be clearly marked.

• Obsolete roads will be ripped and re-vegetated.

Minor Roads • Development of minor roads will be limited and the locations of these will be clearly defined.

• Regularly used minor roads will be watered and regularly maintained.

• Obsolete minor roads will be ripped and re-vegetated.

Materials Handling • Prevention of truck overloading to reduce spillage during ore loading/unloading and hauling.

• A water spray dust suppression system will be used at the primary crusher bin during truck dumping of raw ore.

• All conveyors will incorporate wind covers as necessary.

• Freefall height during ore/waste stockpiling will be limited.

Soil Stripping • Access tracks used for soil stripping during the loading and unloading cycle will be watered.

• Soil stripping will be limited to areas required for mining operations.

Drilling • Dust aprons will be lowered during drilling for collection of fine dust.

• Water injection or dust suppression sprays will be used when high levels of dust are being generated.

Blasting • Fine material collected during drilling will not be used for blast stemming.

• Adequate stemming will be used at all times.

Equipment Maintenance

• Emissions from mobile equipment exhausts will be minimised by the implementation of a maintenance programme to service equipment in accordance with the equipment manufacturer specifications.



HAL-02-07/1/15/00685106.DOC/29/09/03 12

5.2 DUST CONTROL EQUIPMENT Table 7 presents the equipment that will be used to minimise Project dust generation.

Table 7 Dust Control Equipment

Equipment Type Typical Control Area

Water Trucks • Haul roads and exposed trafficked surfaces and all construction sites

Water Sprays • Ore crusher, product conveyors and conveyor feed points on stockpiles

Dust Collection Systems • Drill rigs

Hoods/Covers • Coarse ore stockpile

• Conveyors After: North Limited (1998)

An additional control measure that has been adopted for the Project is the use of a baghouse and associated collection hood/ducting to filter off-gas emissions (ie. to remove dust particles) from the gold room doré melt furnace. Particulate material collected by the baghouse will be returned to the melt furnace periodically (SNC Lavalin, 2003). This control method reduces the potential for any minor environmental emissions from the gold smelting process and maximises the retention of gold product. In accordance with Consent Condition 6.2(i) Barrick will maintain and use sufficient equipment to apply dust suppression water to unsealed and trafficked areas at a rate which minimises dust emissions (Tables 4, 5 and 6). Dust control equipment will be maintained in accordance with a site maintenance schedule that is based on equipment manufacturer’s specifications. The EPA does not recommend the description of specific rates of dust control watering or treatment of stockpiles in a DMP (EPA, pers. comm., 5 June 2003). Suitable rates of application of dust suppression water will be determined on an ongoing basis through on-site experience and will be largely related to soil types, variability in mine traffic volumes and meteorological conditions (for example, higher watering rates will be applied on hot, dry, windy days when large numbers of vehicles are trafficking massive-structured soil types than on wet days). Specific application rates are not prescribed in this DMP due to the potentially high day to day variability in weather conditions. It will be the responsibility of the Construction or Operational Manager (in co-operation with the Environmental Manager) to assess and implement suitable rates of water application to minimise dust emissions from trafficked and unsealed areas.

5.3 STOCKPILE SURFACE TREATMENT In accordance with Consent Condition 6.2(iii), Barrick will treat all stockpiles (eg. apply dust suppression and/or revegetate) as necessary to minimise windblown dust emissions (Table 5). As above, specific dust suppression activities will be determined by the Construction or Operational Manager in co-operation with the Environmental Manager. Measures to control wind-borne dust and sediment runoff from stockpiles include the following: (i) stripping and placement of soil stockpiles at appropriate moisture conditions whenever possible;

(ii) watering of stockpiles during construction when conditions indicate the need;


HAL-02-07/1/15/00685106.DOC/29/09/03 13

(iii) the application of mulch over completed soil stockpiles and monitoring the rapid revegetation of soil stockpiles (either unassisted or assisted, via the application of seed, fertiliser and water) to promoted rapid cover and as a consequence, erosion control;

(iv) construction of stockpiles of appropriate height and batter angles; and

(v) minimisation of runoff to stockpile areas. The control of wind-borne dust along the pipeline and borefield areas includes the regular inspection of works and any stockpile areas and rapid enactment of any remedial or response measures with respect to dust and soil/sediment control.

5.4 REHABILITATION Further to the above controls, rehabilitation works will be undertaken progressively as construction activities and mining proceed, in accordance with Consent Condition 3.6 and Section 5 of the EIS. Rehabilitation will be undertaken promptly in accordance with a progressive rehabilitation programme. The rehabilitation programme general principles include (North Limited, 1998): (i) The rehabilitation of Project landforms is to be progressive and conducted in accordance with

approved, verified plans which are to be updated annually.

(ii) The stability of newly prepared (ie. topsoiled) landforms prior to the establishment of long term vegetation is to be protected via the construction of moisture-retaining graded drains, water-holding structures (eg. surface depressions) and, where appropriate, the use of authorised hybrid cover crops to provide initial erosion protection.

(iii) Rehabilitation of the outer embankments of the tailings storages to be grassed during processing operational years, reducing habitat opportunities for avifauna.

(iv) Endemic groundcover, understorey, and tree seed and seedlings would be cultivated and utilised.

(v) The annual rehabilitation programme and budget is to be prepared by a site team incorporating the Project’s senior management.

Rehabilitation works will be detailed in the Mining Operations Plan (MOP) in accordance with the requirements of the DMR (DMR, 2002). The MOP describes all mining and mining related activities, rehabilitation plans and land use outcomes over the MOP period (maximum 7 years). The MOP must be in a format endorsed by the DMR and must contain plans and text which identify and define the area(s) proposed to be disturbed, mining and rehabilitation method(s) to be used and progressive rehabilitation schedules. For each area to be rehabilitated, the MOP will describe, where relevant (DMR, 2002): • physical and chemical characteristics of mining and processing waste of emplaced material

relevant to rehabilitation;

• method of land shaping;

• characteristics of all cover material including sealing/drainage layers, subsoil/topsoil;

• thicknesses of cover layers and methods of laying and compaction;

• drainage and erosion control consistent with material characteristics or erosion risk;


HAL-02-07/1/15/00685106.DOC/29/09/03 14

• final landform profile and slopes;

• soil treatment;

• vegetation species and methods of their establishment;

• the extent to which agreed rehabilitation outcomes and land use have been met; and

• maintenance activities/requirements. In accordance with Consent Condition 6.2(ii), effective rehabilitation will be ensured by: • the implementation of the rehabilitation programme in accordance with the above general

principles;

• rehabilitation maintenance work;

• rehabilitation monitoring activities; and

• compliance with DMR’s Mining Rehabilitation and Environmental Management Process (which includes the above DMR MOP and annual reporting requirements [Section 10]) (DMR, 2002).

Where practicable, disturbed areas will be seeded and stabilised with appropriate groundcover immediately following construction, to provide surface stability and an effective means of controlling dust (Tables 4 and 5). Additional DMR requirements relating to rehabilitation and/or dust control are included in the Mining Lease (ML 2000) conditions. Relevant conditions are provided in Section 1.

It will be the responsibility of the Environmental Manager in co-operation with the Construction or Operational Manager to meet the requirements of the DMR with regard to rehabilitation and dust control.

6 ADDITIONAL MODIFICATION OF MINING OPERATIONS TO MINIMISE DUST EMISSIONS

6.1 REQUIREMENT FOR ADDITIONAL MODIFICATIONS OF OPERATIONS With the implementation of the air quality safeguards and controls outlined above, the distance from operational areas of any bird breeding or native flora areas and given extent of Barrick-owned land surrounding the Project (Figure 2), negligible air quality impacts are anticipated at non-Company owned residences or at bird breeding or native flora areas. Notwithstanding, there may be occasions when additional modifications to mining operations may be required to further minimise Project dust emissions due to a particular emission issue. For example: • a short term dust generation event – eg. excessive dust emissions under unfavourable

meteorological conditions such as a hot, dry and windy day; or

• an amenity criteria exceedance – eg. in the event that the air quality monitoring programme indicates a continuing or episodic Project related exceedance of EPA amenity criteria at a non-Company owned residence or a bird breeding/native flora monitoring area.

Management procedures for modifying the mining operation to address these issues are provided below and are illustrated on Figure 4. Examples of applicable control methods which would be implemented during these procedures to minimise potential dust emissions are provided in Tables 4, 5 and 6.

6.2 DUST MANAGEMENT PROCEDURES

6.2.1 Standard Management Procedure The standard management procedure is to be implemented to minimise dust emissions from day-to-day Project activities. Implementation of the procedure will be the responsibility of the Construction or Operational Manager in cooperation with the Environmental Manager. When considering potential dust generation issues at the Project, the following should be considered by the Operational Manager in cooperation with the Environmental Manager: • The nearest non-company owned residence is located approximately 3.5 km north of the Project

ML at “Coniston” (Figure 3).

• The major bird breeding areas associated with Lake Cowal occur in the wooded and vegetated parts to the north of the lake viz. in the Lignum/River red Gum expanses some 4.5 km to the north of the Project area (Resource Strategies et. al., 1997).

• Soil erosion or erosion of stockpiles by winds begins to occur at windspeeds in excess of 5.4 metres per second (m/s) (Quality Urban Air Review Group [QUARG], 1996).

• Baseline meteorological data which indicates that the Project area is strongly influenced by winds from the south-west. Wind speeds during the year are generally moderate and usually range between 6 and 10 kilometres per hour (km/hr) (1.67 to 2.77 m/s), increasing up to 20 km/hr (5.54 m/s) in summer during the afternoons (North Limited, 1998). The Project air quality safeguards and control measures outlined in Section 5 were developed to achieve suitable dust control under this range of conditions.

The standard management procedure includes the following: Source Identification and Prediction The first step of the standard management procedure involves identification of the mining activities that will be conducted and the potential for dust generation. The following should be considered: • the methods and types of equipment that will be used;

• the timing of the dust generating activity;

• the location of the activity (in relation to surrounding topography and landuse);

• the prevailing climatic conditions, including current conditions (Section 7.1) and weather forecasts; and

• the environmental conditions Including lake water levels, season and bird breeding activities.

In addition, if hourly average wind speeds on site are greater than 5.6 m/s (20 km/hr) from the south and general environmental conditions are conducive to dust generation (eg. hot and dry), the Environmental Manager or his/her delegate will be required to review dust generation levels on-site, and assess the requirement for implementing additional modifications to the mining operation to minimise dust emissions, particularly from exposed areas. If the source identification and prediction step indicates a requirement to modify the operation to reduce dust emissions, a modification strategy will be required.


HAL-02-07/1/15/00685106.DOC/29/09/03 17

Modification Strategy This component involves determination of how the mining operation will be modified to include additional dust control and management methods to minimise dust emissions, based on the results of the identification stage. The Operational Manager in cooperation with the Environmental Manager may adopt a range of modifications to the mining operation. Typical modifications that can be adopted are outlined in Table 8, however, additional modification measures may also be adopted as required.

Table 8 Modifications to Dust Generating Activities

Project Component Modification

General Exposed Areas Increased watering of exposed surfaces via water trucks or other methods as required.

Stockpiles Activating or increasing rates of water application at fixed water sprays on stockpiles and/or transfer points.

Ancillary Activities Temporary cessation of ancillary or non essential on-site dust generating activities (eg. soil stripping).

Notwithstanding the modification to activities, the general air quality safeguards and controls described in Section 5 (Tables 4, 5 and 6) should continue to be implemented. Implementation This stage of the procedure involves implementation of the measures selected in the modification strategy phase. Review The Operational Manager in cooperation with the Environmental Manager would continue to implement these modifications until the conditions that led to the requirement for the modification improve (eg. wind speeds drop sufficiently). An important component of the procedure is the assessment of the effectiveness of the modifications. The Construction or Operational Manager will regularly review the effectiveness of dust controls using visual assessment of dust generation at source (eg. dust generation levels behind vehicles on haul roads) as well as review of general environmental and meteorological conditions and any results that may be available from the dust monitoring programme (Section 7). The review will be conducted daily or more often as determined by the Environmental Manager. If required, the manager will return to the modification strategy phase of the procedure to implement further controls as necessary.

6.2.2 Amenity Criteria Management Procedure The objective of the amenity criteria procedure is to identify longer term strategies for mitigating dust levels if EPA amenity criteria for dust deposition are exceeded at non-Company owned residences or bird breeding or native flora areas. It is the responsibility of the Environmental Manager to implement the strategy in cooperation with the Construction or Operational Manager. The procedure includes the following components:


HAL-02-07/1/15/00685106.DOC/29/09/03 18

Amenity Criteria Assessment The results of the dust deposition monitoring programme will be assessed against EPA criteria (Section 2) and reported in the AEMR (Section 10). In the event that the EPA criteria is exceeded, an assessment will be conducted to determine: • the timing of elevated dust levels;

• the general location of the elevated dust levels;

• the climatic conditions at the time of the elevated dust levels;

• potential contributing factors to the elevated dust levels; and

• whether the elevated dust levels are attributable to Project activities. The results of this assessment will be provided to the EPA (and NPWS in the event of exceedances at bird breeding or native flora monitoring sites). Modification Strategy This component involves determination of the modification to operations to minimise dust emissions in the medium to long term, based on the results of the amenity criteria assessment stage of the procedure. The additional dust control, management and modification measures to be adopted (Sections 5 and 6.2.1) will be selected with consideration of: • mine activities scheduled for the next phase of construction/operation;

• possible reasons for previous elevated dust levels;

• additional modifications in the form of control methods or operational changes which could be adopted;

• control equipment that will be utilised; and

• the location of current and future dust generating activities. Implementation This stage of the procedure involves implementation of the dust control and management methods selected in the modification strategy process. Review The effectiveness of the additional dust control and management measures adopted will continue to be assessed against the EPA criteria in accordance with the monitoring programme (Section 7). If required, the Environmental Manager will return to the management strategy phase of the procedure in consultation with the EPA (and NPWS if required). This DMP presents management procedures to minimise potential dust related impacts at the outset of the Project. The development of any additional dust control measures (including modifications to Project activity) is expected to be an iterative process, based on specific issues, observations and empirical data.


HAL-02-07/1/15/00685106.DOC/29/09/03 19

7 AIR QUALITY MONITORING PROGRAMME The existing Project air quality monitoring programme utilises a network of dust deposition gauges (Figure 3). Dust deposition gauges are analysed monthly for ash content, combustible matter and insoluble solids. Levels of metals in the dust (ie. aluminium, arsenic, cadmium, lead, selenium, zinc and copper) are also analysed at six monthly intervals. Additionally dust levels outside of the Project MLA area will be monitored to aid in the continued improvement of dust control methods. The primary objective of dust control at the Project is to limit the Project air quality emissions to within acceptable levels as defined by the air quality criteria detailed in Section 2. It will be the responsibility of the Environmental Manager to implement the monitoring programme prior to the commencement of construction and to ensure monitoring is conducted in accordance with applicable standards and guidelines as described in Sections 7.2 and 7.3. The air quality monitoring programme for the Project has been formulated from: • consent condition requirements; • results of baseline studies conducted for the EIS; and

• consideration of the potential impacts resulting from the Project. The monitoring programme will be used to assess compliance with consent conditions and to review dust management strategies. In accordance with Consent Condition 6.1(a) the location of all monitoring sites (dust deposition and TSP) has been determined in consultation with the EPA (EPA, pers. comm., 5 June 2003) and NPWS (NPWS, pers. comm., 21 May 2003). In accordance with Consent Condition 8.3, the following monitoring programme has been developed to “monitor dust deposition rates and concentrations of total suspended particulates (TSP) for the life of the mine, including monitoring impacts of dust on any surface water within the high water mark of Lake Cowal.” In accordance with Consent Condition 8, the air monitoring programme will be “revised/updated annually, unless otherwise directed by the Director-General, to reflect changing environmental requirements, significant changes in technology/operational practices and results from monitoring conducted”.

7.1 METEOROLOGY In accordance with Consent Condition 8.1, an on-site meteorological station will provide data to be used for predicting dust impacts on nearby residences and bird breeding areas. An automated meteorological station is currently located at the exploration office and records rainfall, wind speed, wind direction and temperature. The station will be relocated to continue to monitor meteorological conditions during Project operations. When used in conjunction with the air quality monitoring results, meteorological data (in particular, wind speed, wind direction and rainfall) will provide useful information for the management of dust emissions (Section 6) and review of dust management practices.


HAL-02-07/1/15/00685106.DOC/29/09/03 20

7.2 DUST DEPOSITION GAUGES A network of 15 static dust gauges will be used to monitor dust deposition in the vicinity of the Project during construction and operations (Figure 5). In accordance with Consent Condition 6.1(a) and (c), 8.3(a) and 8.3(b) dust deposition monitoring sites will be located: • at Gumbelah Homestead (DG6) (Consent Condition 6.1(a));

• within the high water mark of Lake Cowal (DG4 and DG5) (Consent Condition 8.3(b));

• proximal to known bird breeding areas in the north of Lake Cowal (DG2 and DG3) (Consent Condition 6.1(a)); and

• within native flora areas (DG4, DG8, DG9 and DG10) (Consent Condition 6.1(a)). These dust monitoring sites have been located and agreed in consultation with the EPA (EPA, pers. comm., 5 June 2003) and NPWS (NPWS, pers. comm., 21 May 2003). In addition, dust deposition monitoring will be continued at Site 52. Site 52 is the only EIS baseline monitoring site which is not located directly within Project infrastructure disturbance areas. Sites 51 and 54 are located within disturbance areas and continued monitoring at these locations is not practical or required given the range of monitoring sites proposed. Dust deposition monitoring at the sites established to continue the EIS baseline monitoring programme (Section 3.2.1 and Figure 3) will continue (excluding sites 51 and 54). A summary of the dust deposition monitoring sites agreed in consultation with EPA (EPA, pers. comm., 5 June 2003) and NPWS (NPWS, pers. comm., 21 May 2003) is provided in Table 9 along with the rationale for site location.

Dust Monitoring Locations



HAL-02-07/1/15/00685106.DOC/29/09/03 22

The siting of individual dust monitoring sites will be undertaken in accordance with Australian Standard (AS) 2922 Ambient Air - Guide for the Siting of Sampling Units (Appendix B) which sets out the process for selection of monitoring sites and positioning the sampling units, and AS 3580.10.1-1991 - Methods for sampling and analysis of ambient air - Determination of particulates - Deposited matter - Gravimetric method (Appendix C). For dust gauges Sections 8 and 9 of AS 2922 and Section 7 of AS 3580.10.1 relevantly require: • The site shall be level ground, free, as far as practicable, from foreign sources of pollution such

as chimneys, traffic, incinerators, trees, dusty ground and road traffic. If a local foreign source exists in the area, it shall be noted and mapped.

• The gauge to be located at least 5 m from the nearest obstacle.

• There should be unrestricted airflow of 360o around the sampling site.

• There should be a clear sky angle of 120o above the sampling inlet.

• The height of the funnel aperture above the surface of the immediate surrounding area shall be 2 m (±0.2 m) and the funnel aperture plane should be horizontal.

• In general, the period of exposure shall be 30 (±2) days. All collection and analysis of dust gauge samples will be conducted in accordance with AS 3580.10.1 which sets out the principles, reagents, apparatus, sampling procedures, results calculations and precision, test report format and diagrams of sampling equipment for dust deposition monitoring (Appendix C). Dust deposition samples will be analysed monthly for ash content, combustible matter and insoluble solids. The dust deposition results will be compared with the criteria presented in Section 2. All dust deposition monitoring results will be reported in the AEMR (Section 10).

7.2.1 Analysis of Metals in Dust Samples In the majority of situations, dust produced by mining operations is chemically inert, consisting of particles of exposed soil and rock (Environment Australia, 1998). However, there is a perception that dust generated from the Project could potentially contain elevated levels of heavy metals that could adversely impact the water quality of Lake Cowal. This issue arose in submissions to the EIS and at the Commission of Inquiry. In order to address the concern and as a continuation of baseline analysis, composite dust samples will be analysed for select metals (ie. aluminium, arsenic, cadmium, lead, selenium, zinc and copper) at six monthly intervals for comparison to average crustal abundance levels (Bowen, 1979). The concentrations of metals collected in dust gauges during mining operations will be compared to the baseline dust monitoring metals results (Section 3).

7.2.2 Dust Deposition Monitoring within Lake Cowal In accordance with Consent Condition 8.3(b), Site DG5 has been initially positioned near the centre of Lake Cowal so that it remains within the surface water area under a range of lake water level conditions (currently dry). However, if access to this site for collection of data proves difficult under high water levels, an alternative site would be agreed with regulatory authorities. Monitoring at DG5 and other dust deposition gauges located in and around the lake (Figure 5) will provide results representative of potential dust impacts on any surface waters within the high water mark of Lake Cowal.


HAL-02-07/1/15/00685106.DOC/29/09/03 23

7.2.3 Surface Water Monitoring Programme In addition to the dust monitoring programme outlined above, surface water quality monitoring in Lake Cowal will be undertaken to assess the impacts of the Project on lake waters. Analysis of surface water monitoring results in conjunction with dust deposition monitoring data will provide for monitoring of the potential impacts of dust on any surface water within the high water mark of Lake Cowal in accordance with Consent Condition 8.3(b). For example, the relative dust deposition results at sites DG3 and Site 52 (Figure 5) will allow comparison of dust deposition levels within the high water mark of Lake Cowal, both immediately adjacent to the mine and at the opposite side of the lake. If surface water is present, water monitoring results from water quality monitoring sites adjacent to the mine and at the opposite side of the lake can similarly be compared and any differences in water quality examined in light of the dust monitoring data (including metals concentrations in dust and surface waters). A description of the surface water monitoring programme components relevant to monitoring of potential dust impacts on Lake Cowal waters is presented below. The locations, frequency and parameters/analytes of surface water monitoring within Lake Cowal at its associated watercourses that are relevant to the dust monitoring programme are summarised in Table 10. The full surface water monitoring programme is outlined in the Surface Water, Groundwater, Climate and Aquatic Biological Monitoring Programme (SGWMP) and is consistent with the EIS (North Limited, 1998).

Given the ephemeral nature of Lake Cowal, surface water monitoring will not be possible at all times. If Lake Cowal is dry, surface water monitoring will commence after a significant inflow occurs at any of the four inflow sites (Bland Creek, Sandy Creek, irrigation channel and/or Lachlan floodway) or when sufficient water collects in the lake and enables water quality monitoring.


HAL-02-07/1/15/00685106.DOC/29/09/03 24

Water quality monitoring samples will be subject to laboratory analysis at a NATA registered laboratory, with a field test used to determine turbidity. Surface water sample collection, preservation and general maintenance will be in accordance with AS 5667:1998 Water quality – Samples and the SWGMP. The surface water monitoring data will be reported in the AEMR and will be reviewed and revised annually as part of the AEMR review process. Should analysis of relevant surface water monitoring data (Table 10) and data from the dust gauge network indicate adverse effects of Project dust on surface waters within the high water mark of Lake Cowal, additional dust suppression and control measures will be implemented in accordance with the procedures detailed in Section 6.2.

7.3 TOTAL SUSPENDED PARTICULATE HIGH VOLUME SAMPLER The proposed TSP monitoring site is shown on Figure 5. Monitoring will be conducted at HV1 at the ‘Coniston’ Homestead to the north of the Project. The location and selection of a single TSP monitor has been agreed by the EPA (EPA pers. comm., 5 June 2003). The TSP monitor is located at the nearest non-Company owned residence to the Project as the TSP criteria adopted by the EPA were recommended by the National Health and Medical Research Council of Australia as the maximum permissible level of TSP in the air to protect public health in residential environments (Pavel Zib and Associates, 1997). All other non-company owned residences are more than 3.5 km from the Project and monitoring at these distant locations is not warranted given the EIS predicted that the Project would result in only minor exceedances of the dust deposition and TSP criteria outside of the Project MLA area (Pavel Zib and Associates, 1997). The monitoring of TSP will be conducted by high volume sampler in accordance with procedures established with the EPA namely Approved Methods for the Sampling and Analysis of Air Pollutants in New South Wales (Appendix A). TSP will continue to be monitored for the life of the mine unless otherwise agreed by the Director-General. The siting of the monitoring unit will be undertaken in accordance with AS 2922. For TSP high volume samplers Sections 8 and 9 of AS 2922 relevantly require that: • There should be unrestricted airflow of 360O around the sampling site.

• There should be a clear sky angle of 120O above the sampling inlet.

• The sampler shall be 1 to 1.5 m above the ground surface.

• Sampler located at least 20 m from trees.

• No boiler or incinerator flues nearby.

• Located at least 50 m from roads.

• Power supply and vehicular access should be available. TSP will be measured to assess fluctuations in particulate matter concentrations on a six day cycle (ie. a 24 hour sample is collected every six days). The high volume sampler will be fenced if necessary to exclude stock. All sample collection and analysis will be conducted in accordance with AS 2724.3-1984: Ambient Air – Particulate Matter – Determination of Total Suspended Particulates (TSP) – High Volume Sampler Gravimetric Method (Appendix D). AS 2724.3 sets out the principles, apparatus, calibration, procedures, results calculations and accuracy, test report format and diagrams of sampling equipment for TSP high volume samplers. In addition to the dust deposition and TSP monitoring programmes, visual assessments of dust generating activities will be periodically conducted by the Environmental Manager or his/her delegate to identify the major dust generating activities on-site (Section 6).


HAL-02-07/1/15/00685106.DOC/29/09/03 25

7.4 REVIEW OF MONITORING PROGRAMMES

The results of the meteorological, TSP and dust deposition monitoring will continue to be maintained in a database for examination and assessment. This data will be used to analyse relationships between short-term variations in dust levels and the number and distribution of any dust-related complaints. Results of the analysis will then be used in the review of the monitoring programme to determine if further monitoring is necessary (eg. additional dust deposition gauges) or whether the programme can be modified in consultation with the EPA to monitor dust deposition only (no TSP). The results of this review process will be reported annually in the AEMR (Section 10). An IEA will be conducted in accordance with Consent Condition 8.8. The condition is reproduced below:

HAL-02-07/1/15/00685106.DOC/29/09/03 27

(ix) By year 5 of mining operations the Applicant shall, in consultation with CEMCC, identify and discuss post mining issues, particularly in relation to reduced employment and consequent impacts on West Wyalong, and develop a plan for the phase out of the mine workforce. The plan will be reviewed during the year of mining operations following the scale down of the year 8 mining operation workforce. The impacts of the year 8 scale down shall be monitored by the Applicant and results used in planning for full mine closure.

(x) The Applicant shall, in consultation with the CEMCC, develop appropriate strategies to support activities which promote special interest tourism related to the co-existence of mining and the Lake Cowal environment.

The CEMCC will comprise representatives of Bland Shire Council (BSC), Lake Cowal Environmental Foundation (LCEF), two Barrick representatives and four community representatives including one from the Lake Cowal Landholders Association. The CEMCC will provide opportunities for members of the community to attend CEMCC meetings to discuss specific issues relevant to them, including dust-related issues. This will be achieved by landholders making a request to the CEMCC regarding a particular issue, or by the landowner registering a complaint in the complaints register. Landowners who register complaints will be invited to join in discussion of the issue at the next CEMCC meeting. Items of discussion at these meetings will include mine progress, reporting on environmental monitoring, complaints, rehabilitation activities and any environmental assessments undertaken.

9 COMPLAINTS AND PROPERTY ACQUISITION IN THE EVENT OF DUST AFFECTATION

A process for the handling of complaints, resolution of disputes and land acquisition in the event of affectation is provided below in accordance with the requirements of Project consent conditions and to facilitate prompt and comprehensive responses to any community concerns that relate to dust.

9.1 COMPLAINTS REGISTER A complaints register will be maintained by the Environmental Manager in accordance with Consent Condition 10.1(a). The condition is reproduced below:

Preliminary investigations into the complaint will commence within 48 hours of complaint receipt. In the event that the complainant is not satisfied with Barrick’s response to the complaint, or exceedance of EPA criteria has been demonstrated, an independent investigation will be undertaken (Section 9.2).

9.2 INDEPENDENT INVESTIGATION PROCESS Consent Condition 11.1(a) outlines the independent investigation process in the event that a landowner considers dust levels are in excess of relevant EPA criteria at their dwelling. The consent condition is reproduced below. Consent Conditions 11.1(b) to (e) are reproduced in Section 9.3.

11.1 Area of Affectation - Land Acquisition (including resolution of disputes)

Note: In Condition 11.1 (a)-(e) "land" means the whole of a lot in a current plan registered at the Land Titles Office as at the date of this consent.

(a) (i) In the event that landowners consider that noise and/or dust from the Cowal Gold mining

operations at their dwelling(s) is in excess of the criteria set out in this consent or the relevant EPA amenity criteria for noise and/or dust levels, and the Director-General, in consultation with the EPA, is satisfied that an investigation is required, the Applicant shall upon receipt of a written request:

• appoint a qualified independent person to undertake direct discussions with the landowners affected to ascertain their concerns and to plan and implement an investigation to quantify the impact and determine the sources of the effect, and

• bear the cost of the independent investigation and make available plans, programmes and other information necessary for the independent person to form an appreciation of the past, present and future mining operations and their effects on noise and/or dust emissions.

(ii) The investigation is to be carried out by a qualified independent person in accordance with a documented Plan. The Plan shall be designed and implemented to measure and/or compute (with appropriate calibration by measurement) the relevant noise and/or dust levels at the complainant’s dwelling emitted by the current normal mining operations.

(iii) The independent person, the Plan and the timing of its implementation shall be approved by the Director-General, in consultation with BSC, the EPA, the affected landowner and the Applicant. A report of the investigation shall be provided to the Director-General, the EPA, the Applicant and the affected landowner.

(iv) The results of the investigation shall be assessed and reported by the independent person in the light of the mine’s current operations and proposed short, medium and long term development plans.

(v) If the independent noise and/or dust investigation finds that the relevant criteria are being exceeded by noise and/or dust emission from normal mining operations, the Applicant shall:

• modify those areas of the mining operation which are causing the exceedances; or

• undertake other measures, as agreed with the affected landowner, to ameliorate the effects of the impact, within three (3) months or as otherwise directed by the EPA.


HAL-02-07/1/15/00685106.DOC/29/09/03 29

(vi) Within two (2) months after the expiry of the three (3) month period in sub-clause (v) above, and upon written request from the landowner, the Applicant shall arrange for a further independent noise and/or dust investigation to be completed.

(vii) If the investigation in sub-clause (vi) above finds that the relevant noise and/or dust emission levels from normal mine operations exceed relevant amenity criteria, the Applicant shall purchase the property within six months of receipt of a written request from the owner of the affected property.

(viii) Further independent investigations shall cease if the Director-General, in consultation with the EPA is satisfied that the relevant consent limits or EPA amenity criteria are not being exceeded and are unlikely to be exceeded in the future.

In the event that a request to purchase a property is received by Barrick in respect to Consent Condition 11.1(a)(vii) property acquisition would occur (Section 9.3).

9.3 PROPERTY ACQUISITION DUE TO DUST AFFECTATION Consent Condition 11.1(b),(c),(d) and (e) outlines the process for acquisition of a property in the event of demonstrated dust affectation (Section 9.2). The consent condition is reproduced below:

(b) In respect of a request to purchase land arising under Condition 11.1(a), the Applicant shall pay the owner the acquisition price which shall take into account and provide payment for:

(i) a sum not less than the current market value of the owner's interest in the land used for its existing use at the date of this consent who is the occupier and all improvements thereon at this date as if the land was unaffected by the development proposal.

(ii) the owner's reasonable compensation for disturbance allowance and relocation costs within the Bland or Forbes Local Government Areas.

(iii) the owner's reasonable costs for obtaining legal advice and expert witnesses for the purposes of determining the acquisition price of the land and the terms upon which it is to be acquired.

(c) In the event that the Applicant and any owner referred to in Condition 11.1(a) cannot agree within the time limit upon the acquisition price of the land and/or the terms upon which it is to be acquired, then:

(i) either party may refer the matter to the Director-General, who shall request the President of the Australian Institute of Valuers and Land Economists to appoint a qualified independent valuer, suitably qualified in compensation issues, who shall determine, after consideration of any submissions from the land owner and the Applicant, the acquisition price.

(ii) in the event that the independent valuer requires guidance on any contentious legal, planning or other issues, the independent valuer shall refer the matter to the Director-General, who if satisfied that there is need for a qualified panel, shall arrange for the constitution of the panel. The panel shall consist of:

1) the appointed independent valuer,

2) the Director-General, and/or

3) the President of the Law Society of NSW or his/her nominee.

The qualified panel shall, on the advice of the valuer, determine the issue referred to it and advise the valuer.

(d) The Applicant shall bear the costs of any valuation or survey assessment requested by the Director-General in accordance with Conditions 11.1(a) - 11.1(c).

(e) Upon receipt of a valuation, the Applicant shall offer to acquire the relevant land at a price not less than the said valuation. Should the Applicant's offer to acquire not be accepted by the owner within six (6) months of the date of such offer, the Applicant's obligations to such owner and in respect of that property under Conditions 11.1(a) - 11.1(e) above shall cease.

The General Manager or Environmental Manager will manage the above process if required.

1. IntroductionThis document lists the methods to be used for sampling and analysing air pollutants in NewSouth Wales for statutory purposes. The document covers:

• pollutants in emissions from stationary sources, including continuous monitoring ofsuch emissions

• pollutant emissions from motor vehicles

• components in and properties of petroleum products

• pollutants in ambient air.

This document is referred to in:

• the Clean Air (Plant and Equipment) Regulation 1997

• the Clean Air (Motor Vehicles and Motor Vehicle Fuels) Regulation 1997.

It may also be referred to in conditions attached to statutory instruments, such as licences ornotices, issued under environment protection legislation, as defined in the Protection of theEnvironment Administration Act 1991.

Industry has an obligation to ensure compliance with limits specified in the Clean Air (Plantand Equipment) Regulation 1997, the Clean Air (Motor Vehicles and Motor Vehicle Fuels)Regulation 1997 and certain statutory instruments. All monitoring to show compliance mustbe done in one of three ways:

• in accordance with the methods specified in this document

• in accordance with the methods specified in the relevant statutory instrument

• if no method is specified in either this document or the statutory instrument, in amanner approved by the EPA in writing before any tests are conducted.

In exceptional circumstances, the EPA may approve the use of alternative methods to thoseprovided here. An application for approval of a test method as an equivalent alternative to atest method in this document (the 'approved method') must be made in writing to the ChiefScientist, Environment Protection Authority.

The application must:

1. show that there are exceptional circumstances that justify the use of a method otherthan the approved method

2. give details of the alternative method for which approval is sought

3. show that the alternative method is scientifically sound

4. show that the alternative method would produce results comparable to those producedby the approved method.

The EPA will not approve an alternative test method unless it is satisfied that the applicationfor approval gives adequate details of the proposed alternative method as listed above.

Any other method, which has been approved by the EPA in accordance with the approvalprocedures set out above as an equivalent alternative to a test method of a particular numberin this document, is prescribed as a test method of that same number.

2. Sample collection and handling


Collect, handle and preserve samples according to the relevant test method. Collect them atthe locations determined in accordance with the relevant regulation or specified in thestatutory instrument, as the case may be. If the regulation does not provide for determinationof the locations or if no locations are specified in the instrument, collect them from suchlocations that they are representative of the total or known portion of the source emissions.

Whenever a United States Environmental Protection Agency (USEPA) test method refers toMethod 1—Sample and Velocity Traverses for Stationary Sources, Standards Association ofAustralia, AS 4323.1-1995 must be substituted. Whenever a USEPA test method refers toMethod 5—Determination of Particulate Emissions from Stationary Sources, AS 4323.2-1995must be substituted.

When determining compliance with the emission limits for oxides of nitrogen in the CleanAir (Plant and Equipment) Regulation 1997, sample during the normal operation of the plantor equipment being tested, not during start-up or shutdown operations. (Start-up is when theplant or equipment is brought up to its normal operating conditions from inactivity byfollowing a prescribed series of steps or operations. Shutdown is when the plant orequipment is taken out of service from normal operation to inactivity by following aprescribed series of steps or operations.)


When siting ambient air sampling units, follow AS 2922-1987. Monitoring sites are classifiedinto three types: peak, neighbourhood or background. When selecting a monitoring site, youneed to consider many parameters, including possible chemical or physical interference,locality, terrain, services and local activities. Try to locate wind speed and direction meterswith the ambient air monitoring instruments unless appropriate wind data are available fromanother nearby source.

3. Methods for sampling and analysisAnalyses should be carried out by a laboratory accredited to perform them by an independentaccreditation body acceptable to the EPA, such as the National Association of TestingAuthorities (NATA).

Methods approved by the EPA for specific analytes and parameters are listed in Tables 1 to 3.In most cases, standard methods are referenced, with additional guidance or clarificationgiven if needed. Where there is no suitable published method, a complete description of theapproved method is given. Refer to Test method sources, for the organisations that publish theapproved methods.

Refer to Generic procedures and definitions that apply to stationary source monitoring andreporting.

All volumes and concentrations are normally reported as dry at a temperature of 0°C and at anabsolute pressure of 101.3 kilopascals (kPa). The EPA’s monitoring requirements may alsospecify a reference gas level to which the result must be corrected.


The results of any monitoring required by a statutory instrument must be provided as asummary report signed by the licence holder or, where there is no licence, by the personrequired to provide the report. The report must contain at least the following information foreach air contaminant, unless the statutory instrument states otherwise:

• name and address of reporting organisation or individual

• date of issue of the report

• the test method used and details of any deviation from that method

• period of monitoring (start and end dates and percentage of time the instruments wereon-line)

• location of monitoring points (normal address and Australian Map Grid reference,height above nominal ground level, and a description of the terrain features)

• the air pollutants measured, the monitoring instruments used, and a description of theair sampling system

• maximum hourly average concentration, daily average concentration, and appropriatelonger-term averages

• appropriate statistical information to describe the variability and range of theconcentrations

• any factors that may have affected the monitoring results

• the precision of the results (using AS 2706 as a guide)

• details of the most recent calibration of each instrument used to take measurements.

Generic procedures and definitions that apply tostationary source monitoring and reporting

Adjustment to reference and equivalent values

1. Oxygen

For adjustment to an oxygen reference, the adjusted concentration of a pollutant, Cb, isdetermined by:

Cb = Ca × (21 – reference oxygen concentration as volume %) ÷ (21 – measured oxygenconcentration as volume %)

where Ca is the measured concentration of the pollutant.

2. Carbon dioxide

For adjustment to a carbon dioxide reference, the adjusted concentration of a pollutant, Cc, isdetermined by:

Cc = Ca × 12 ÷ measured carbon dioxide concentration as volume %

where Ca is the measured concentration of the pollutant.

3. Reference values

4. Nitrogen dioxide


23

Oxides of nitrogen (NOx) from combustion of fossil fuels consist predominantly of nitricoxide (NO) and nitrogen dioxide (NO2). Oxides of nitrogen concentrations are converted toequivalent NO2 thus:

Equivalent NO2 = calculated NO2 + (measured NO × 46 ÷ 30)

where:

calculated NO2 = measured NOx – measured NO46 = molecular weight of NO2

30 = molecular weight of NO

Both NO and NOx must be measured directly, and all concentrations must be expressed inppm.

Cubic metre (m3)

In this document a cubic metre refers to the volume of dry gas that occupies 1 m3 at atemperature of 0°C (273 K) and at an absolute pressure equivalent to 1 atmosphere (101.3kPa).

Measuring concentrations and volumes in gases

When reporting concentrations of pollutants in gases for comparison with emission standardsor with limits in regulations, licences, approvals, statutory notices, guidelines, codes ofpractice or environmental management plans, you must use the following conversions.However, where any of these conversions are part of the test method used to determine theconcentration, they do not need to be repeated for reporting.

The test method for a pollutant gives the volume of gas sampled at the test conditions(temperature, pressure) at the sample point, Va.

• Determine the moisture content (MC, %) of the gas at the sample point in accordancewith USEPA Method 4.

• Calculate the volume of dry gas at sample point conditions (Vb):

Vb = Va × (100 – MC) ÷ 100 ... (1)

• Calculate the volume of dry gas at standard temperature (273 K) (Vc):

Vc = Vb × 273 ÷ (273 + gas meter temperature in °C) ... (2)

• Calculate the volume of dry gas at standard temperature and pressure (Vd):

Vd = Vc × (gas meter pressure in kPa) ÷ 101.3 ... (3)

• Divide the measured mass of pollutant (Ma ) by Vd to determine the concentration (Ca):

Ca = Ma ÷ Vd ... (4)


24

Test method 17—Determination of sootMeasure the concentration of soot emitted from a source with the True Spot Smoke TesterModel RCC-B, the Oil Burner Smoke Scale and the filter paper supplied by Bacharach Inc.,625 Alpha Drive, Pittsburgh, PA, USA. Tel: 0011 1 412 963 2000.

Insert the clean sampling tube, extended if necessary, into the gas stream to be tested. Connectit to the smoke tester. Insert a strip of filter paper into the slot at the end of the tester andtighten the clamp screw. Pull the smoke tester pump handle steadily through 10 full strokes:take 3 to 4 seconds for each pull motion, pause a further 3 seconds at the end of each stroke,then return the pump handle to its original position.

Loosen the clamp screw and examine the paper to see whether any soot has produced a smokespot on the paper. Move the filter paper to a new position in the smoke tester slot. Repeat thetest until consecutive smoke spots on the paper are of equal shading.

Match the colour of the smoke spots on the filter paper to the closest spot on the Oil BurnerSmoke Scale. Hold the scale at arm's length against an opaque white page. Slide the filterpaper behind it so that you can see the spot on the filter paper through the holes in the centresof the colour spots on the scale.

Test method 19—Determination of total mass of unburntorganic vapours from vapour disposal units

Sampling

Draw the exhaust gases through a 316 stainless steel probe to a sample line of PTFE or 316stainless steel held at a temperature of at least 105°C.

Pass the exhaust gases to a device capable of reducing the moisture content of the gases to adew point of less than 3°C. Filter the sample gases to remove entrained particles.

Analysis

Pass the conditioned sample gases to the following two analysers.

Hydrocarbon analyser (flame ionisation detector type)

Set the analyser to zero with air that has a hydrocarbon concentration of less than 10 ppm byvolume of propane. Calibrate it with a gas of known propane concentration to give adeflection of between 20% and 90% of full scale on the range being used.

The average of the indicated concentration of hydrocarbons in the conditioned sample gasesmust lie between 30% and 90% of full-scale deflection of the analyser. The combined effectsof carbon dioxide and carbon monoxide in the gases must not affect the reading by more than2% of full-scale deflection. The deviation from linear response of the analyser must notexceed 2.5% of full-scale deflection.

Carbon dioxide analyser (non-dispersive infrared type)

Set the analyser to zero with nitrogen that has a carbon dioxide concentration of less than0.05% by volume. Calibrate it with a gas of known carbon dioxide concentration to give adeflection of between 20% and 90% of full scale on the range being used.

The analyser must have a full-scale range for carbon dioxide concentration lying between 0%and 14% and 0% and 20% by volume. The deviation from linear response of the analysermust not exceed 2.5% of full-scale deflection.

Calculation of mass of unburnt organic vapours

The mass of unburnt organic vapours in each cubic metre of the exhaust gases is equal to:

C ÷ (42.3 × L) grams ... (1)

where:

C = the average concentration of hydrocarbons measured as equivalent propane in ppm overthe test period42.3 = a conversion factorL = the average concentration of carbon dioxide content expressed as a percentage of samplegases.


26

Test method 20—Determination of total mass ofunrecovered organic vapours from vapour recovery units

Sampling

Draw the exhaust gases through a sample line of PTFE or 316 stainless steel construction.Pass them to a hydrocarbon analyser (flame ionisation detector type).

Analysis

Set the analyser to zero with air that has a hydrocarbon concentration of less than 10 ppm byvolume of propane. Calibrate the analyser with a gas of known propane concentration to givea deflection of between 20% and 90% of full scale on the range being used.

The average of the indicated concentration of hydrocarbons in the exhaust gases must liebetween 30% and 90% of full-scale deflection of the analyser. The combined effects ofcarbon dioxide and carbon monoxide in the gases must not affect the reading by more than2% of full-scale deflection. The deviation from linear response of the analyser shall notexceed 2.5% of full-scale deflection.

Calculation of mass of unrecovered organic vapours

The mass of unrecovered organic vapours emitted for each litre of organic liquid is:

(318 × C × A × M × P × V) ÷ (L × T) milligrams ... (1)

where:

C = the average concentration of hydrocarbons expressed as equivalent propane in ppm overthe test periodA = the cross-sectional area of the exhaust duct at the plane where the measurements aremade, in m2

M = the total time for organic liquid to pass into the tank or out of the industrial plant, inminutesP = the atmospheric pressure in kPaV = the average exhaust gas velocity in metres per secondL = the volume of organic liquid passing into the tank or out of the industrial plant, in litresT = the average exhaust gas temperature in kelvins (273 + temperature in °C)318 = a conversion factor


27

Test method 21—Calculation of vapour pressureA volatile organic liquid for which the Reid Vapour Pressure may be ascertained shall bedeemed to have a vapour pressure exceeding 75 kilopascals if the maximum bulk storagetemperature of the liquid is greater than the temperature specified in Column 2 of the tablebelow corresponding to the Reid Vapour Pressure of the liquid specified in Column 1.

Where the Reid Vapour Pressure of the liquid lies between two adjacent values specified inColumn 1 of the table, the corresponding temperature may be calculated as though a linearrelationship existed between the Reid Vapour Pressure and the temperature at and betweenthose two values.

Where the Reid Vapour Pressure of the liquid lies outside the values specified in Column 1 ofthe table or cannot be determined, the vapour pressure of the liquid shall be calculated bysuch methods as the EPA may determine.

Test method 27—Lead concentration in leaded andunleaded petrolThe lead in all petrol must be determined with this test method. The method was developedby the EPA from the standard test methods AS 1876-1990 Petrol (Gasoline) for MotorVehicles and ASTM D3237-97 Standard Test Method for Lead in Gasoline by AtomicAbsorption Spectrometry.

Applicability

This method is independent of the lead alkyl type.

Principle

The petrol sample is diluted with methyl isobutyl ketone, and the alkyl lead compounds arestabilised by reaction with iodine and a quaternary ammonium salt. The lead content of thesample is determined by atomic absorption flame spectrophotometry at 283 nm. Standardsprepared from reagent-grade lead chloride are used for calibration.

Range

Lead concentrations in the range 0.005 to 1 g/L can be determined. Higher leadconcentrations require dilution with iso-octane before analysis.

Sampling and storage

Containers for samples from bowsers, tanks, delivery tanks, tank vehicles or pipeline

Sampling containers must be metal cans with welded side seams and a minimum capacity of250 mL. Each container must have an opening at the top of 30 to 50 mm in diameter. The topmust be sealed with a vapour-tight screw cap.

Number of samples

Take two samples of the petrol to be tested and analyse the lead content of each. If requested,leave a third sealed sample with the owner or the person in charge.

Sampling from a bowser

Pour the petrol directly from the nozzle of the bowser hose into the top opening of the samplecontainer. Fill the container to near capacity.

Sampling from a tank, delivery tank, tank vehicle, pipeline, fuel tank or motor vehicle

Take a representative sample. Pour it into a sample container for transport.

Storage

Store samples at 0° to 8°C. Bring them to room temperature before analysis.

Cleaning procedures

Rinse the sampling containers with acetone (propanone) or iso-octane. Dry them in a dryingcabinet at 40°C or higher.

Reagents

• MIBK: methyl isobutyl ketone (4-methyl-2-pentanone) (AR grade).

• Iodine solution: Dissolve 3.0 g AR grade iodine in AR grade toluene and dilute to 100mL with the toluene. Store in a brown glass bottle.

• Aliquat 336: Tricapryl methyl ammonium chloride.

• 10% Aliquat 336/MIBK solution: Dilute 100 mL of Aliquat 336 to 1 L with MIBK.

• Intermediate stock lead solution (100 mg/L): Transfer accurately by pipette 5 mL ofstock lead solution to a 100 mL volumetric flask. Dilute to the mark with 10% Aliquat336/MIBK solution. Mix well and store in a brown glass bottle.

• Iso-octane: 2,2,4-trimethylpentane (AR grade).

• Nitric acid (1+1): Mix equal volumes of concentrated AR grade nitric acid anddistilled water.

• Acetone (AR grade).

Maximum storage periods for reagents:

iodine solution 30 days

10% Aliquat 336/MIBK 30 days

1% Aliquat 336/MIBK 30 days

stock lead solution 30 days

Standard lead solution 1 day

Grades of reagents other than those indicated may be used on two privisos:

• The reagent is of high enough purity to permit its use without lessening the accuracyof the determination.

• The same source of reagent is used for all standards and blanks.

Analysis

General

Glassware must be de-leaded by rinsing with dilute nitric acid (1+1) and then rinsed withdistilled water. Wash the glassware with acetone and dry it at 50° ± 5°C.


32

Preparation of working standards (2, 5, 10, 20 mg/L)

Transfer accurately by pipette 1.0, 2.5, 5.0 and 10.0 mL of the intermediate stock leadsolution (100 mg/L) to four 50 mL volumetric flasks. Adjust the volume of each to 10 mL byadding 1% Aliquat/MIBK solution and add 10 mL of iso-octane. Add 0.1 mL of iodinesolution, mix well and allow to react for at least 1 minute. Dilute to volume with MIBK andmix.

Preparation of the blank

To a 50 mL volumetric flask add 30 mL of MIBK then 10 mL of iso-octane. Add 0.1 mL ofiodine solution, mix well and allow to react for at least 1 minute. Add 5 mL of 1%Aliquat/MIBK solution and mix. Dilute to volume with MIBK and mix.

Preparation of sample

• For petrol with a lead concentration of < 0.1 g/L: To a 50 mL volumetric flaskcontaining 30 mL of MIBK and 10 mL of petrol sample, add 0.1 mL of iodinesolution. Mix well and allow to react for at least 1 minute. Add 5 mL of 1%Aliquat/MIBK solution. Dilute to volume with MIBK and mix.

• For petrol with a lead concentration of 0.1–1 g/L: To a 50 mL volumetric flask add 30mL of MIBK. Add 1–5 mL of petrol sample and enough iso-octane to yield a finalsample volume of 10 mL. Add 0.1 mL of iodide solution, mix well and allow to reactfor at least 1 minute. Add 5 mL of 1% Aliquat/MIBK solution. Dilute to volume withMIBK and mix.

• For petrol with a lead concentration of > 1 g/L, dilute with iso-octane before analysis.

Preparation of the atomic absorption spectrophotometer

Optimise the instrument for lead at 283.3 nm. Using the blank, adjust the gas mixture(acetylene/air) and aspiration rate to obtain an oxidising lean, blue flame. Aspirate the 20mg/L lead working standard and adjust the instrument to achieve maximum response.

Standardisation and analysis

Aspirate the reagent blank and adjust the instrument to zero. Measure the absorbances of the2, 5, 10 and 20 mg/L lead working standards. Aspirate the samples and record the absorbancevalues. Aspirate the blank between each sample measurement.

For instruments without a direct concentration readout, prepare a calibration curve by plottingthe absorbance of the working standards against their concentrations (mg/L) on linear graphpaper.

Calculations

Read the lead concentration in g/L directly from the instrument readout or calculate it byreferring to the appropriate calibration curve:

Lead concentration in petrol sample (g/L) = (C × V1) ÷ (V2 × 1000)

where:

C = lead concentration (mg/L) of sample (as read from graph or instrument readout)V1 = final volume (50 mL)V2 = volume of sample petrol (mL)

Test method 31—Observation procedure for excessive airimpurities: visible emissionsWhen an observer is determining if a vehicle is being used in breach of the clause limitingvisible emissions, the following principles apply:

• The observer must be satisfied that the vehicle generating the visible emissions iscorrectly identified.

• The observer must be satisfied that the emissions are visible not just because of heat orthe condensation of water vapour.

• The emissions must be continuously visible for more than 10 seconds.

The following details of the observation must be recorded:

• Length of time in seconds that the visible emissions were observed.

• Registration number of the motor vehicle under observation.

• Type of motor vehicle under observation.

• Colour and darkness, in the opinion of the observer, of the air impurities emitted.

• Location, date and approximate time of day that the observation was made.


34

Other approved method 9—Determination of “coarse”particulatesTo determine “coarse” particulates:

• determine total solid particles using TM-15;

• simultaneously determine “fine” particulates (PM10 emissions) using OM-5; then

• subtract the result of OM-5 (PM10 or “fine” particulates) from the result of TM-15(Total solid particles) to determine “coarse” particulates.

The two methods must be carried out simultaneously, over the same sampling period toensure the influence of process change does not impact on the results.
