Not all species listed under the EPBC Act have been mapped (see below) and therefore a report is a general guide only.Where available data supports mapping, the type of presence that can be determined from the data is indicated in generalterms. People using this information in making a referral may need to consider the qualifications below and may need to seekand consider other information sources.

For threatened ecological communities where the distribution is well known, maps are derived from recovery plans, Statevegetation maps, remote sensing imagery and other sources. Where threatened ecological community distributions are lesswell known, existing vegetation maps and point location data are used to produce indicative distribution maps.

- seals which have only been mapped for breeding sites near the Australian continent

Such breeding sites may be important for the protection of the Commonwealth Marine environment.

For species where the distributions are well known, maps are digitised from sources such as recovery plans and detailedhabitat studies. Where appropriate, core breeding, foraging and roosting areas are indicated under 'type of presence'. Forspecies whose distributions are less well known, point locations are collated from government wildlife authorities, museums,and non-government organisations; bioclimatic distribution models are generated and these validated by experts. In somecases, the distribution maps are based solely on expert knowledge.

1 INTRODUCTION & SCOPE OF WORKS

The Odour Unit WA Pty Limited (TOU) was commissioned by Aurigen to undertake a

desktop Calpuff dispersion modelling assessment of a proposed Waste Transfer and

Resource Recovery Facility (WTRRF), which is comprised of a putrescible waste

transfer station and a materials recovery facility, to be located at Jackson Street,

Bassendean Western Australia.

The aim of the modelling is to determine the risk of odour impacts offsite, and assess

compliance against the currently accepted Department of Environment Regulation

(DER) odour concentration criterion which is in place in lieu of a formal guidance

which is due in 2016.

Compliance with the criterion will be compared to the nearest sensitive receptor

locations outside of the surrounding commercial/industrial area.

1.1 SCOPE OF WORK

The study was carried out as a Desktop Odour Modelling Assessment with odour

emission rates (OER) compiled from TOU’s own database and that of other relevant

public domain assessments. The scope of works for the modelling assessment is as

follows.

Develop and run a site-specific odour dispersion model for the WTRRF

projecting odour impacts from the site;

Follow the requirements set by DER (formerly Department of Environment –

DoE) for odour impact assessments [1], [2]

as summarised below:

o Identify and quantify all emissions to atmosphere (odour) with a potential

to have a non-trivial impact on the environment. Emissions of potential

concern include (among others) odorous gases to be considered

explicitly, unless the proponent can demonstrate that the emission rates

of these are insignificant;

[1]

Department of Environment: Air Quality Modelling Guidance Notes, March 2006

[2] Department of Environment Regulation Guidance Statement: Separation Distances, Division 3, Part V,

Environmental Protection Act 1986, Draft released for Consultation August 2015



o For all those odour sources that cannot be dismissed as being of no

significance, the proponent must provide model predictions of the impact

of emissions in the form of concentrations and/or rates of deposition over

the range of averaging periods normally associated with relevant

standards for each pollutant, and assess the magnitude of this impact

against the relevant standards;

o Modelling results to be presented in the form of:

contour plots covering the region of interest (including population

centres or isolated residences), with a grid density adequate to

avoid significant loss of resolution, and

numerical values of concentrations at the point(s) of maximum

impact (explain where this occurs) and other locations (receptors)

of interest (e.g. places of human residence).

o When cumulative concentrations are modelled, in order for the

contribution to be properly assessed, the modelling results are presented

for:

the existing emissions plus background concentration (pre-

proposal),

the proposed development in isolation (excluding existing

emissions), and

the combined (existing plus proposed plus background)

emissions.

o Any estimates of emissions employed in modelling assessments are

realistic and that uncertainty is balanced by conservatism;

o The modelling must properly assess both emissions which are

continuous in nature and emissions which are intermittent. Intermittent

emissions which are insignificant in magnitude and/or very improbable in

the lifetime of the plant may be screened out and the remaining

emissions modelled together on a probabilistic basis to estimate the total

plant impact;

o The models and/or worst case calculation procedures and data

employed in the assessment must be demonstrably capable of

simulating, or accounting for, all of the features which are important in



the context of determining the air quality impact of the project. The

proponent is responsible for identifying and properly accommodating

these;

o If using a conventional model, the proponent will need to obtain at least

one (preferably two or more) year's data on the meteorology of the area,

with high data recovery and verifiable data accuracy. In the simplest

situations, the data may be limited to that necessary to provide reliable

hourly average estimates, at a representative site, of:

wind speed,

wind direction,

air temperature,

mixing height, estimated or measured via methods acceptable to

the DER, and

atmospheric stability, estimated by a method acceptable to the

DER.

The proponent’s report should include a description of the meteorological data used or

alternatively a reference to a publicly available report which contains this information.

The Calpuff assessment was carried out against the following odour modelling

criterion:

The modeled odour concentrations at the “most exposed existing or likely future

off-site sensitive receptors” should be compared with the following guideline

values:

i. 0.5 ou, 1-hour average, 99.5th percentile for tall stacks;

ii. 2.5 ou, 1-hour average, 99.5th percentile for ground-level sources

and down-washed plumes from short stacks;

AND

iii. For facilities that do not operate continuously, the 99.5th

percentile must be applied to the actual hours of operation.

The WA DEC also has a preference for the near-field criteria of:

iv. 8.0 ou, 1-hour average, 99.9th percentile.



1.2 REGULATORY GUIDANCE FOR DETERMINING RISK

Regulatory authority guidelines for odorous impacts of gaseous process emissions are

not designed to satisfy a ‘zero odour impact criteria’, but rather to minimise the

nuisance effect to acceptable levels of these emissions to a large range of odour

sensitive receptors within the local community.

The DER is undergoing significant environmental regulatory reform in developing a

comprehensive risk-based approach to its regulatory functions under Part V Division 3

of the Environmental Protection Act 1986. Consequently there has been a review and

amendment for the determination of Separation Distances based on contributions

from:

i. Guidance for the Assessment of Environmental Factors - Separation Distances

between Industrial and Sensitive Land Uses, No.3 (June 2005, Western

Australia); and

ii. Environment Protection Authority Victoria’s Guideline: Recommended

separation distances for industrial residual air emissions (2013).

The current Draft Guidance for Separation Distances [2] (August, 2015) prescribes

separation distances for:

o Category 61A (Solid waste facility: 1,000 tonnes or more per year; Premises

(other than premises within category 67A) on which solid waste produced on

other premises is stored, reprocessed, treated, or discharged onto land);

o 500m from the nearest sensitive receptor, and

o Category 62 (Solid waste depot: 500 tonnes or more per year; Premises on

which waste is stored, or sorted, pending final disposal or re-use);

o 200m from the nearest sensitive receptor.

The WTRRF will reside within the existing industrial/commercial industrial area and

does satisfy a minimum recommended 500m separation distance (refer Figure 1).

This assessment determines the projected odour buffer of the proposed WTRRF and

compares it to the generic distance of 500m. The separation distance will be

measured according to Method 1 [2] (urban method):

http://www.der.wa.gov.au/images/documents/our-work/regulatory-reform/Regulatory-functions.pdf



Method 1 measures the separation distance from the activity boundary of the

industry (odour source) to the property boundary of the nearest sensitive land

use;

Method 1 should be applied where the nearest sensitive land use is

either:

o in an urban area or township; or

o on a site less than 0.4 hectares, or in a zone allowing

subdivision to be less than 0.4 hectares.

2 WTRRF FACILITY (ODOUR SOURCE) OVERVIEW

The WTRRF comprises of primarily a putrescible Waste Transfer Station (WTS) and a

Materials Recovery Facility (MRF), with a proposed capacity of 100,000 tonnes per

annum (tpa) of putrescible and C&I waste streams for the WTS, and an additional

100,000 tpa of recyclables into the MRF.

A summary of the building design and layout (refer Figure 2) is as follows:

· An “L” shaped building of approximately 80m x 77m (longest sides) x 15m high

(at apex), comprising;

o the north, east and south faces of the building to have 5m high concrete

push walls(estimated 230mm thick),

o the remaining heights on the north, east and south faces to have

zincalume wall cladding to roof height,

o The interface between the 5m high push walls and the cladding to be

sealed with an impervious seal, and

o Proposed roof vents along the apex to allow for natural, passive

ventilation.

The WTRRF will have six (6) 4m x 5m access doorways. The WTS area will have

three (3) access doorways where only 2 are operational at any one time. The MRF will

have two (2) access doorways. The sixth door is for maintenance and contingency

and will remain shut otherwise.

An additional seventh doorway is also operational at the western end of the MRF

building. This doorway is used to allow the transfer of sorted recyclables to other

storage buildings on the site.

A summary of site operations is as follows:

1. Approximately 274 tonnes of putrescible waste daily (average) is expected

(based on 100,000 tpa with 365 days of waste acceptance/annum);



a. approximately 30 x 9 tonne incoming putrescible waste trucks daily,

b. approximately 47 incoming MRF (comingled recyclables) waste trucks

daily,

2. Waste is unloaded from trucks onto the WTS bunker area (24m x 18m) where

there are 2 operational bays for unloading; it is then moved by front end loader

into the hopper for compaction before removal from site;

a. each outgoing compaction bulk haulage truck to carry 50 tonnes per

truck movement,

b. up to 120 tonnes of residual waste is expected to be left on the bunker

floor each night,

3. No sorting of putrescible waste will be done at the site;

4. The WTS and MRF building will be fully enclosed (doors proposed to remain

open during operational hours) with large truck access doors on one side of the

building with the initial design to have passive ventilation at the roof apex;

5. Unloading time of incoming trucks is approximately 15 minutes per delivery;

a. Outgoing bulk compaction trucks do not factor into timeframes into/out of

WTRRF,

6. Peak delivery periods are expected twice daily for 2 hours each;

7. In the event of a malfunction or breakdown the total waste stream will be

removed using bulk haulage; and

8. All site leachate generated within the WTS and MRF building is captured and

treated onsite with residual discharged directly to sewer.

3 AIR EMISSION ASSUMPTIONS & ODOUR EMISSION RATES

3.1 AIR EMISSION ASSUMPTIONS

The WTS and MRF “L” shaped building (“the building”) initial design proposes to have

roof vents allowing for passive airflow out of the building.

The total void area of these vents is assumed to be approximately 100m2 comprising

of, for example, a 80m longitudinal vent with a 0.5m void on each side along the

length of the MRF; and a 20m longitudinal vent with a 0.5m void on each side along

the length of the building, or a combination of roof top “whirly birds” or similar

ventilation means.

Under any wind condition, the external building pressurisation under a heavy gust of

high winds, and/or pressurisation of the building when the vehicle doors are opened

would not cause a complete and instantaneous venting of the building. Given the

internal air pressure is largely equalised with ambient conditions due to the passive

roof vents, it is more likely that the turbulence created from opened doorways would

shift the air within the building rather than induce an immediately exit flux of air.

a) It is proposed to have a number of access doorways remain open for the duration

of daily activities which means that the entire building will undergo mixing of air;

i. With doorways remaining open and ongoing mixing of the building the

fugitive odour escaping would be dilute since the volume of MRF air

(negligible odour) is able to mix and dilute the odorous air emanating from

the putrescible waste stockpile within the waste bunker.

b) There is also scope to consider the partitioning of the WTS area from the MRF

essentially confining odour to the WTS area alone;

i. Under a partitioning scenario the bulk odour would be confined to the WTS

area with only nominally a 10% carryover of the odour strength into the MRF

area.



If it is assumed that ventilation would occur along the vent/void area commensurate

with prevailing winds; then it can be assumed that at worst case the entire downwind

total void would be an emission source at any one time, although this is unlikely.

Under a westerly (SW – NW) prevailing wind origin the downwind void area comprises

of the five (5) access doorways, each of 20m2 when opened. Easterly winds (NE –

SE) would blow into the building and the downwind void area would be the roof vents

of approximately 100m2 in total void area. Therefore, under any wind condition the

downwind void represents approximately 100m2 of emissions interface.

The velocity of airflow through the entire downwind 100m2 void at any one time is

assumed as 1m/s accounting for a low wind speed, constant fugitive air emission.

Doorways will be closed in the evenings and agitation/transfer of putrescible wastes

will cease; however, the building is assumed to still be emitting fugitive air. The fugitive

emission air volume is thus 100m3/s, or 360,000m3/hr. This represents approximately

6 air changes per hour (360,000m3/hr / 62,000m3) which is considerably

overestimated where in TOU’s experience typically naturally ventilated waste transfer

stations exhibit 2-4 air changes per hour depending on design.

c) These air changes represent the entire WTS and MRF building volume of

62,000m3.

d) Where the building is partitioned, the volume within the WTS area is 21,645m3. If

the downwind void still represents 100m2, then the air changes therein are >16/hr

for the WTS area where the bulk odour is contained.

3.2 COMPILING & DETERMINING ODOUR EMISSION RATES

TOU has undertaken numerous site-specific odour assessments of putrescible waste

transfer stations throughout Australia. Additionally, there are many public domain

assessment reports where odour strengths were measured for the purposes of

dispersion modelling. The concentrations of odour strengths sampled from some of

these sites are listed in Table 3.2.1 below.

The range of odour concentrations listed in Table 3.2.1 represent off-peak and peak

time periods where waste volumes are changing. The average odour concentration

from the first 4 data points is 550ou.

TOU has chosen the average value of 550ou to represent the continuous odour

strength within the WTS and MRF building. This value effectively smooths the odour

concentrations throughout each operational day by accounting for the range of odour

strengths emitted during off peak and peak periods.



3.2.1 Odour Emission Rates for a Contiguous (non-partitioned) Building

Applying the average derived odour concentration to the fugitive air emission rate of

100m3/s gives an odour emission rate of 55,000ou/s throughout the building. When

the operational periods have ceased inside the WTS area, and the MRF remains

operational but no putrescible waste is being processed/transported, it is assumed

that only 5% of the total odour emission rate will be emitted.

3.2.2 Odour Emission Rates for a Partitioned Building

When partitioned, the WTS area will contain the bulk of the odour emission of

55,000ou/s. TOU estimates that 90% of this bulk rate will be assigned to the WTS

area, whilst the partitioned MRF is estimated to contain 10% of the bulk emission rate

due to some diffusion between the partitioning curtains. When the operational periods

have ceased inside the WTS area, and the MRF remains operational but no

putrescible waste is being processed/transported, it is assumed that 5% of the odour

emission rate will be passively emitted from the WTS area, but no odour will permeate

into the MRF area since the partitioning curtains are static.

4 ODOUR DISPERSION MODELLING METHODOLOGY

4.1 THE CALPUFF ODOUR DISPERSION MODEL

The odour dispersion modelling assessment was carried out using the CALPUFF

System (Version 7). The main system programs are:

CALPUFF - Version 7.2.1 - Level 150618

CALMET - Version 6.5.0 - Level 150223

CALPOST - Version 7.1.0 - Level 141010

CALPUFF is a multi-layer, multi-species, non-steady-state puff dispersion model that

is able to simulate the effects of time- and space-varying meteorological conditions on

pollutant transport (USEPA). CALMET is a meteorological model that produces three

dimensional gridded wind and temperature fields to be fed into CALPUFF [3]. The

primary output from CALPUFF is hourly pollutant concentrations evaluated at gridded

and/or discrete receptor locations. CALPOST processes the hourly pollutant

concentration output to produce tables at each receptor and contour plots across the

modelling domain. The result is a summary of pollutant concentrations at various time

averages and percentiles or a tally of hours where a pollutant has exceeded a pre-

determined concentration [3]. For further technical information about the CALPUFF

modelling system refer to the document CALPUFF Modeling System Version 6 User

Instructions [3].

The CALPUFF system can account for a variety of effects such as non-steady-state

meteorological conditions, complex terrain, varying land uses, plume fumigation and

low wind speed dispersion (USEPA). CALPUFF is considered an appropriate

dispersion model for impact assessment in one or more of the following applications:

complex terrain, non-steady-state conditions,

buoyant line plumes,

coastal effects such as fumigation,

high frequency of stable calm night-time conditions,

high frequency of calm conditions,

inversion break-up fumigation conditions

long-range transport, and

close-field assessments.

For this study, the air contaminant was odour and ground level concentrations in

odour units (ou) have been projected.

4.2 GEOPHYSICAL AND METEOROLOGICAL CONFIGURATION

A CALMET hybrid three-dimensional meteorological data file for Bassendean, Perth

Western Australia was produced that incorporated gridded numerical meteorological

data supplemented by surface observation data, topography and land use over the

domain area.

4.2.1 Terrain configuration

Terrain elevations were sourced from 1 Second Shuttle Radar Topography Mission

(SRTM) Derived Smoothed Digital Elevation Model (DEM-S). The SRTM data has

been treated with several processes including but not limited to removal of stripes,

void filling, tree offset removal and adaptive smoothing [4]. The DEM-S was used as

input into TERREL processor to produce a 39km2 grid at 0.25km resolution. Coastline

data was sourced from USGS Global Self-consistent Hierarchical High-resolution

Shoreline (GSHHS) Database [5]. A map of the terrain is illustrated in Figure 4.1.

4.2.2 Land use configuration

Land use was sourced from the United States Geological Survey (USGS) Global Land

Cover Characteristics Data Base for the Australia-Pacific Region [6]. The data was

used as input into CTGPROC processor to produce a 39 km2 grid at 0.25 km

resolution.

4.2.3 Geophysical configuration

The geophysical data file was created using the MAKEGEO processor. Land use data

from CTGPROC and terrain data from TERREL was used as input to produce a 39

km2 geophysical grid at 0.25 km resolution.

4.2.4 Meteorological configuration

4.2.4.1 Input data

Five years of the latest one-hour average observed meteorological surface data was

sourced from the Perth International Airport Automatic Weather Station (AWS)

maintained by the Bureau of Meteorology (BoM). The location of Perth Airport surface

station and other metadata are available in Appendix A. Once reviewed the data was

sorted and processed using the chi-x test algorithm to define the most representative

year out of the last five years of data. The representative year was 2012. The BoM

data was formatted into generic format and was processed with SMERGE to produce

a surface meteorological data file.

A 3D data tile from TAPM was developed for numerical meteorological data and

processed with CALTAPM into a suitable format. TAPM was run using multiple

nested grids, at least three nests and 35 vertical levels. TAPM innermost nest was

40km2 at 1 km resolution. The nested grid resolutions were close to a ratio of three as

possible.

4.2.4.2 CALMET meteorological model configuration

CALMET was run using the hybrid option that uses geophysical data, surface station

data from Perth Airport and upper air data from the TAPM 3D data tile. The data was

used to initialise the diagnostic functions of the CALMET module to produce a full 3D

meteorology data for input into CALPUFF. Table 4.1 shows key variable fields

4.2.4.3 Meteorological data analysis

Observed 2012 BOM surface data was compared with longer term climate (2010 –

2015) from Perth Airport to gauge how representative and suitable the year is for the

purpose of air quality dispersion modelling. The chi-squared test algorithm was used

to determine this representative year. For reference, meteorological data was also

extracted from the CALMET model for the location directly nearby the proposed

Bassendean WTRRF site.

The 2012 Annual Windroses (Figure 4.2) show bias to easterly winds, likely due to

the close proximity to the Darling Scarp with the sea breeze effects dominant from the

south-west.

Autumn and Winter seasons show a strong dominance of north-easterly winds with

sea breeze effects in the Summer and Spring months.

Dominant light winds occur between the hours of 1900hrs – 0600hrs as expected

(Figure 4.3). Under light wind conditions the odour dispersion is poor and impacts are

at their greatest.

4.3.2 Receptor configuration

Receptors were spaced at 50m x 50m (250m; 5 x nesting factor) over a 3.5km x

4.75km domain centred over the Bassendean WTRRF site. Sensitive receptors were

placed at three of the nearest offsite industrial locations as well as two at the nearest

north-west and south-east sensitive receptors. The coordinates of sensitive receptors

4.3.5 CALPUFF Model Options

CALPUFF default model options were set except for the following as recommended in

Table A-4 contained and explained within Barclay and Scire [7]:

Dispersion coefficients (MDISP) = dispersion coefficients from internally

calculated sigma v, sigma w using micrometeorological variables (2);

Probability Density Function used for dispersion under convective conditions

(MPDF) = Yes (1); and

Minimum turbulence velocities sigma v for each stability class over land and

water (SVMIN) = 0.2 m/s for A, B, C, D, E, F (0.200, 0.200, … , 0.200).

4.4 ODOUR DISPERSION MODELLING SCENARIOS & ODOUR EMISSION RATES

The following scenario/s were simulated with CALPUFF:

i. Non-Partitioned building representing mixing of air throughout. Total Odour

Emission Rate (OER) of 55,000ou/s emitted continuously during daily operational

hours with the percentage of odour assigned as follows:

o WTS assigned 23% of Total OER based on operational surface area;

o MRF assigned 77% of Total OER; and

o After Hours the continuous OER emitted was 5% of the Total OER.

ii. Partitioned building representing mixing of air throughout. Total Odour Emission

Rate (OER) of 55,000ou/s emitted continuously during daily operational hours

with the percentage of odour assigned as follows:

o WTS assigned 90% of Total OER;

o MRF assigned 10% of Total OER; and

o After Hours the continuous OER emitted was 5% of the Total WTS OER.

[7]

Barclay, J. & Scire, J., 2011. Generic Guidance and Optimum Model Settings for the CALPUFF

Modeling System for Inclusion into the ‘Approved Methods for the Modeling and Assessments of Air Pollutants in NSW, Australia’



4.4.1 Modelling Assumptions

The entire WTS and MRF building is an “L” shaped building where the WTS has an

operational area of approximately 23% (952m2) of the entire surface area. Under the

scenario where there is no partitioning of the WTS and MRF the building is assumed

to have uniform mixing of the total OER. Where partitioning is assumed, 90% of the

total OER is assigned to the WTS area.

The OER is considered to be a constant odour emission during all hours; however, in

the evening periods outside of operational hours only 10% of the total OER is emitted

for the non-partitioned scenario, and 5% for the partitioned scenario. This is because

the WTS is a discrete source when partitioned and access doorways are closed

outside of operational hours. The MRF however is proposed to operate 24hrs so their

doorways are still operational outside of daily operational hours.

Tonnage throughputs although affecting the bulk OER at any one time have been

“smoothed’ by considering an average constant OER which accounts for peak loads

as well as those timeframes where waste is minimal to negligible in the WTS.



5 ODOUR DISPERSION MODELLING RESULTS

The non-partitioned scenario shows that for an odour criterion of:

o 2.5ou; 99.5th percentile with 1-hour averaging times

The model projections demonstrate a “PASS” with respect to the nearest sensitive

receptor locations. There is a slight projection into the open-space north-west of the

site but not impacting housing.

For an odour criterion of:

o 8ou; 99.9th percentile with 1-hour averaging times

The model shows minor impacts on receptors north of the WTRRF site; however,

these projections represent an “upset” condition such as:

a transient peak odour emission when waste is held too long

due to breakdown of outgoing truck movements;

uncontrolled loss of emissions in the morning start-up periods

when doorways are opened and there is decomposed residual

waste that has been held on in the bunker over a weekend

etc.

The partitioned scenario also shows a “PASS” with respect to the nearest sensitive

receptor locations. The partitioning of the building shifts the origin of the bulk odour

emission rate slightly to the east as it is centred within the WTS. The shape of the

offsite odour impact is therefore only marginally changed to reflect a change in the

emission centre.

The partitioned scenario does not reflect the betterment of odour control, rather it

depicts the containment of the odour centred over the WTS rather than mixed

throughout the entire building. Under this scenario there is a greater opportunity to

maintain the bulk odour emission within a discrete area rather than allowing it to

permeate throughout the entire building.

The odour dispersion modelling results have been visually illustrated as odour impact

contours superimposed on a gridded aerial map, specifically, the 2.5ou and 8ou

isopleths for each modelled scenario. A complement of these odour isopleths are

presented in the Figures below.

6 FINDINGS AND CONCLUSIONS

TOU has carried out an odour dispersion modelling assessment of Aurigen’s

proposed Waste Transfer Station at Bassendean, Western Australia. The objectives of

the odour dispersion modelling were to provide three-dimensional CALPUFF odour

modelling to determine if offsite odour would impact the nearest sensitive receptors

outside of the industrial/commercial land use where the WTRRF is situated within.

The CALPUFF modelling system (ASG, 2011) was used to carry out the odour

dispersion modelling. Geophysical data was sourced from national and international

databases for terrain (Gallant, et al., 2011) and land use (USGS, 1997). Input into

the CALMET meteorological model comprised of the processed geophysical data,

observed surface meteorological data sourced from Perth Int’l Airport and numerical

prognostic meteorological data for the Perth region using the derived representative

year available (2012) with >98% raw data recovery. Odour emissions data was

derived from other assessed Waste Transfer Stations throughout Australia and the

average odour strength applied to this assessment.

The results of all modelling show compliance to the relevant DER odour concentration

criteria with respect to the nearest sensitive receptors. Therefore it is concluded that

no adverse odour impacts are expected as a result of the proposed operations of the

Aurigen Bassendean WTRRF, and that modelling projection results for consent

conditions have been shown to pass the relevant criterion.

HALF-HOURLY DATA HOLDINGS

UPPER-AIR EDT DATA HOLDINGS

Holdings calculated up to 01 Nov 2015The % complete figure is the completeness of observations averaged over all months of record, for the given station and observation type,taking gaps into account. For hourly holdings, the completeness is relative to the maximum number of daily observations for the site eachmonth, and is therefore an estimate. For daily holdings, the completeness figure shown is exact.

The single days missed figure is the total number of days for which no observation was received, not including full missed months. The fullmonths missed figure is the total of full month gaps over the period of record. Where an element is not included assumptions can generallybe made about availability, and the list to use has been suggested below.

The following notes have been compiled to assist with interpreting the metadata provided in thisdocument. These notes are subject to change as the network evolves. Changes in station-specific metadataoccur more frequently, both as recent changes are recorded and historical information is transferred frompaper file to electronic database.

Reliability of the metadata

The Commonwealth Bureau of Meteorology maintains information on more than 20,000 stations which haveoperated since observations began in the mid 1800s. The amount of information available for each ofthese sites and its associated uncertainty are influenced by a number of factors including the type andpurpose of the station and the time over which it operated.

Early information about stations was held only on paper file. In 1998 a corporate electronic database wasestablished to help maintain information about the network and its components. The number of parametersrecorded about a station is now much greater than before this database was established. The nationaldatabase has also helped improve consistency in the metadata through the implementation of predefinedfields. As a result, and through the refinement of operating procedures, station metadata recordedsince 1998 are of a higher overall standard than previously, although occasional omissions and errorsare still possible.

The Bureau is part way through a task of entering historical information held on paper file into thecorporate database. Until this process is completed there will remain large gaps in the informationcontained in these metadata documents and considerable caution should be used when derivingconclusions from the metadata. As an example, two consecutive entries about a rain gauge dated 50 yearsapart may appear in the equipment metadata. This may either mean that nothing happened to thatinstrument over the 50 years, or that information for the intervening period has yet to be enteredinto the database. Similarly, if no information was available about instruments at a site when it wasfirst established, fields which were required to have a value present may have used the earliestinformation available as a best-guess estimate. Sometimes this was the metadata current when the databasewas established in 1998. In some instances there may be gaps in metadata relevant to the post 1998 period.

For the above reasons it is recommended that all metadata prior to 1998 be considered as indicative only,and used with caution, unless it has been quality controlled. The Bureau of Meteorology should becontacted if further information or confirmation of the data is required. Depending on the nature of theinquiry there may be a fee associated with this request. Contact details are provided in the telephonebook for each capital city or the Bureau's web site at:http://www.bom.gov.au

The following pages contain explanatory notes for selected terms found in this document.

Station Number

The Bureau of Meteorology station number uniquely specifies a station and is not intended to change over timetime, although on very rare occasions a station number may change or be deleted from the record (usuallyto correct an error). Generally a new station number is established if an existing station changes in a waythat would affect the climate data record for that site (measured in terms of air temperature and precipitation).Significant station moves are an example of this.

Some stations also possess a World Meteorological Organization (WMO) station number. The WMO number isdifferent to the Bureau of Meteorology number. It also uniquely specifies a station at any given time butcan be reassigned to another station if the new station takes priority in the global reporting network.Only selected stations will have a WMO number. Significant stations may maintain their WMO number formany decades.

Network Classification Continued....

Stations may be included in several different networks, which may change over time. The table on theprevious page lists current network classifications related to the scientific purpose of the network.Some of these networks - the GCOS network for instance - are components of a global network. Entriesin the database for some networks may not be complete, thus not properly representing the statusof the network. The composition of the network will usually change over time. While several of thenetworks have international significance, other network classifications have been developed to aidoperational management.

Station Purpose

The station purpose can be classified according to the observation program listed below. Parameters inbrackets list some of the various different configurations which occur.

• Synoptic [Seasonal, River Height, Climatological, Telegraphic Rain, Aeronautical, Upper Air] • Climatological [Seasonal, Telegraphic Rain] • Aeronautical • Rainfall [River Height] • River Height • Telegraphic Rain [Non-Telegraphic River Height, Telegraphic River Height] • Non-Telegraphic Rain [Telegraphic River Height] • Evaporation [Rainfall, River Height, Telegraphic River Height, Non-Telegraphic River Height, Telegraphic Rain, Non-Telegraphic Rain] • Pluviograph [Rainfall, Telegraphic Rain, Non-Telegraphic Rain, River Height, Telegraphic River Height, Non-Telegraphic River Height] • Radiation • Lightning Flash Counter • Public Information • Local Conditions • Radar Site • Unclassified • No Routine Observations

Note: Telegraphic observations are those which are sent by some electronic means be it a phone ortelegram to the responsible Bureau office. It is a term which is historically linked to analogue nonautomatic data transmission.

Station Observation Program Summary

Surface Observations

The following terms are used to describe the frequency of surface observations at a site. Historicalobservation programs will typically be missing for many sites until the database is backfilled withinformation.

Set a) • Continuous Program · More than half hourly observations sent (eg an automatic weather station {AWS} which continuously transmits 10 minute observations). This will automatically include half hourly and hourly observations programs. • Half hourly observations · Half hourly observations sent. This will automatically include hourly observations. • Hourly observations · Hourly observations sent only. Stations report on non-synoptic hours (ie. 0100, 0200, 0400, 0500, etc)






Surface observations continued....

Set b) • Performed · Observations performed, instruments read and observations recorded • Reported · Observations performed, instruments read and reported real time • Seasonal · The program may only be performed during a defined season (such as Fire Weather observations) or the routine program may increase in reporting frequency and/or parameters. The program dates are currently modified at the start and end of each season for stations performing seasonal observations. Historically this was not always the case.

Current Station Equipment Summary

Equipment listed in this metadata product is catalogued under one of systems listed below, appropriate toits application. The "Infrastructure" category has been included since it contains information about themast height of an anemometer (if present).

• Flood Warning • Infrastructure • Radiation • Rainfall Intensity • Surface Observations • Upper Air • Weather Watch {RADAR}

Station Equipment History

Equipment Install/Remove

One of four types of actions can be performed on an instrument in this listing:

Install - A new instrument is installed at the site. This can be either a completely new addition (eg thefirst barometer at the site), or the replacement of an existing instrument with a different type (eg replacingmercury barometer with electronic barometer)

Remove - An instrument can be removed either when it is no longer necessary to measure a particularelement, or when the element is to be measured by an instrument of a different type ( see under "Install"above)

Replace - This occurs when one instrument is replaced with another of the same type (eg Kew patternmercury barometer replacing another Kew pattern mercury barometer)

Share - The same instrument is used for observations under two (or more) systems (eg a rain gauge maybe used within both Surface Observations and Rainfall Intensity systems)

Unshare - The instrument is no longer shared between systems






Calibration

During a site inspection an instrument will be calibrated as either being within or not within the specifiedtolerance in accuracy.

Where a quantative calibration result can be achieved by comparison to a transfer standard (egbarometer comparisons and tipping bucket rain gauge calibrations), the instrument will be recorded as beingwithin or outside the required tolerance. Instruments (such as 203mm rain gauges, screens and evaporationpans) where quantitative calibrations cannot be derived should be regarded as meeting specifications whenthe instrument is in 'good working order'.

This product provides a summary table of the number of times an instrument was found to be out of calibration

Station Detail Changes

This set of metadata indicates when some aspect of the general information about a station has changed.

- STATION

Metadata which are categorised as pertaining to STATION are items of (textual) information describing aspecific attribute of the station. A reference to (nondB seeding) indicates initial information of this fieldhas been sourced from a previous database.

Station position

- Latitude and longitude

Derivation of station latitude and longitude, defined by the location of the rain gauge when it is present,has changed over time. Current practice is to locate or verify open and operational station latitude andlongitude based on Global Positioning System equipment. Methods used to locate a station as described inthis product (latlon_deriv) are as follows: GPS, MAP 1:10000, MAP 1:12500, MAP 1:25000, MAP 1:50000,MAP 1:100000, MAP 1:250000, SURVEY, and Unknown (which is more commonly represented by a null value).The field latlon_error should be used with caution as the method of determining this value has beeninterpreted in different ways over time.

- Height

Determination of heights for observing sites is by survey where possible. Otherwise height may bedetermined using a Digital Aneroid Barometer and a known surveyed point, or derived from map contours.The source of height is provided in the corresponding parameter with a suffix of "_deriv".

Heights which may appear in these metadata are: • aero_ht · The official elevation of the aerodrome which normally corresponds to the altitude of the highest threshold of the runways at that airport; • bar_ht · this represents the height of the mercury barometer cistern or the digital aneroid barometer above mean sea level (MSL); • stn_ht · this normally represents the height of the rain gauge above MSL






- Land Use

To assist the long term understanding of climate change it is important to be able to determine the differences overtime which are attributed to variations in the climate. Since land use has an effect on the micro climate around thesite, and changes in land use will therefore affect the climate record, it is important that the characteristics ofthe site are monitored. Soil types are recorded as they affect the land use and also add to the knowledge of thesite details.

Defined Land use Types. • Non-vegetated (barren, desert) • Coastal or Island • Forest • Open farmland, grassland or tundra • Small town, less than 1000 population • Town 1000 to 10,000 population • City area with buildings less than 10 metres (3 stories) • City area with buildings greater than 10 metres (3 stories) • AirportThe land use code is entered on the station inspection form in the ranges 0 to 100 m, 100 to 1 km and 1km to10 km; ie: • lu_0_100m: Land Use 0 to 100 metres from the enclosure • lu_100m_1km: Land Use 100 metres to 1 kilometre • lu_1km_10km: Land Use 1 kilometre to 10 kilometres

Defined Soil Type (At Enclosure). • unable to determine • sand • black soil • clay • rock • red soil • other

Surface Type (At Enclosure). • unable to determine • fully covered by grass • mostly covered by grass • partly covered by grass • bare ground • sand • concrete • asphalt • rock • other

1 INTRODUCTION

It is proposed to open a Waste Management Facility at 25 Jackson Street in Bassendean – refer

Figure 1.1.

It is understood that the site is existing and currently operates a cardboard/paper baling and scrap

metal baling facilities. The proposed operations will include a putrescibles waste transfer station

(WTS) and a commercial and industrial (C&I) waste Materials Recovery Facility (MRF) and may

include a metal shredder on the site to assist with commodity aggregation activities. The new site

will include three main buildings as follows:

WTS and MRF building which includes designated acceptance areas for the WTS and the

MRF. The building will have up to 6 roller shutter doors (2 for MRF, 3 for WTS, 1 for

maintenance) with 2 doors of the WTS operational at any one time;

Bale Shed (finished products storage); and,

Metal Recycling Facility and Baler / Shredder Shed building which will be extended to house

the existing baler and new metal shredder. This building will be fully open to the north east

side to allow for access to the shredder.

The WTS and MRF each have a capacity of 100,000 tonnes per annum (tpa) consisting of municipal

solid waste (MSW) and C&I waste streams with waste moved to and from site by truck.

The proposed hours of operations for various areas on site are as follows:

WTS, 0600 to 1830 seven days per week

(C&I) MRF, 24 hrs per day

Metal shredder, 0600 to 1800 seven days per week

It is noted the proposed site is located within an industrial area and surrounded by industrial

premises. The nearest noise sensitive premises identified are located on Shalford Street,

approximately 600 metres to the north.

This report assesses the noise emissions from the facility, including truck movements on the

premises, at the surrounding industrial receivers and nearest residences against the requirements of

the Environmental Protection (Noise) Regulations 1997.

Appendix A presents the proposed site plan of the facility on which this assessment is based.

Appendix C contains a description of some of the terminology used throughout this report.

2 CRITERIA

Environmental noise in Western Australia is governed by the Environmental Protection Act 1986,

through the Environmental Protection (Noise) Regulations 1997 (the Regulations).

Regulation 7 defines the prescribed standard for noise emissions as follows:

“7. (1) Noise emitted from any premises or public place when received at other premises –

(a) Must not cause or significantly contribute to, a level of noise which exceeds the

assigned level in respect of noise received at premises of that kind; and

(b) Must be free of –

i. tonality;

ii. impulsiveness; and

iii. modulation,

when assessed under regulation 9”

Project Site

Shalford Street Residences



A “…noise emission is taken to significantly contribute to a level of noise if the noise emission …

exceeds a value which is 5 dB below the assigned level…”

Tonality, impulsiveness and modulation are defined in Regulation 9. Noise is to be taken to be free

of these characteristics if:

(a) The characteristics cannot be reasonably and practicably removed by techniques other

than attenuating the overall level of noise emission; and

(b) The noise emission complies with the standard prescribed under regulation 7 after the

adjustments of Table 2-1 are made to the noise emission as measured at the point of

reception.

Table 2-1 Adjustments Where Characteristics Cannot Be Removed

Where Noise Emission is Not Music Where Noise Emission is Music

Tonality Modulation Impulsiveness No Impulsiveness Impulsiveness

+ 5 dB + 5 dB + 10 dB + 10 dB + 15 dB

Note: The above are cumulative to a maximum of 15dB.

The baseline assigned levels (prescribed standards) are specified in Regulation 8 and are shown in

Table 2-2.

1. highly sensitive area means that area (if any) of noise sensitive premises comprising — (a) a building, or a part of a building, on the premises that is used for a noise sensitive purpose; and (b) any other part of the premises within 15 metres of that building or that part of the building.



The influencing factor applicable at the nearest noise sensitive premises to the north has been

calculated as 7 dB as shown in Table 2-3 and based on the land use map in Appendix B. The

transport factor has been calculated as 2 dB, due to Tonkin Highway being considered a major road

(> 15,000 vehicles per day from MRWA Metropolitan Traffic Digest, 2013/14) within 450 metres of

the residence.

1. highly sensitive area means that area (if any) of noise sensitive premises comprising — (a) a building, or a part of a building, on the premises that is used for a noise sensitive purpose; and (b) any other part of the premises within 15 metres of that building or that part of the building.

It is noted that given the relatively large separation distance to the nearest noise sensitive premises,

it is likely compliance with the Regulations will be driven by the assigned noise levels applicable at

the boundary of the adjacent industrial premises.

In addition, the assigned noise levels are statistical levels and therefore the period over which they

are determined is important. The Regulations define the Representative Assessment Period (RAP) as

a period of time of not less than 15 minutes, and not exceeding 4 hours, which is determined by an

inspector or authorised person to be appropriate for the assessment of a noise emission, having

regard to the type and nature of the noise emission. An inspector or authorised person is a person



appointed under Sections 87 & 88 of the Environmental Protection Act 1986 and include Local

Government Environmental Health Officers and Officers from the Department of Environment

Regulation. Acoustic consultants or other environmental consultants are not appointed as an

inspector or authorised person. Therefore, whilst this assessment is based on a 4 hour RAP, which is

assumed to be appropriate given the nature of the operations, this is to be used for guidance only.

Under regulation 3, nothing in the Regulations applies to the following noise emissions –

(a) noise emissions from the propulsion and braking systems of motor vehicles operating on

a road;

(b) noise emissions from a safety warning device, other than a reversing alarm, fitted to a

motor vehicle operating on a road;

(c) noise emissions from trains or aircraft (other than model aircraft and trains operating on

(iii) it is a requirement under another written law that such an alarm be fitted; and

(iv) it is not practicable to fit an alarm that complies with the written law under

which it is required to be fitted and emits noise that complies with these

Regulations;



It is considered that reversing alarms fitted to commercial vehicles and mobile plant e.g. HV trucks

or loaders, are not exempt under the Regulations since they are not specifically required under

another written law. The commonly used fixed noise output tonal reversing alarms also known as

'reversing beeper' emit, by their very nature, tonal and modulating noise at high levels. As such, this

type of reversing alarm generally cannot comply with the Regulations even at distant receivers.

If deemed to be required, an alternative reversing alarm type should be sourced. Such alternative,

which can more readily comply with the Regulations, include alarms emitting a broadband signal in-

lieu of a tonal 'beep'.

3 METHODOLOGY

3.1 Site Measurements

Site visits were conducted on the 13 April and 15 June 2016 to determine the sound power levels of

various equipment and ambient noise levels applicable to the nearby industrial receivers.

The equipment used was a Rion sound level meter type NA28 and the following is noted in regard to

the sound level meter:

The equipment holds current laboratory certificates of calibration that are available upon

request. The equipment was also field calibrated before and after the Event and found to be

within +/- 0.5 dB.

The microphone was fitted with a standard wind screen.

The microphone was approximately 1.4 metres above ground level and at least 3.0 metres

from reflecting facades (other than the ground plane).

3.2 Noise Modelling

Computer modelling has been used to predict the noise emissions from the proposed operations.

The advantage of modelling is that it is not affected by background noise sources and can provide

the noise level for various weather conditions and operating scenarios if necessary.

The software used was SoundPLAN 7.4 with the CONCAWE algorithms selected. These algorithms

have been selected as they are one of the few that include the influence of wind and atmospheric

stability. Input data required in the model are:

Meteorological Information;

Topographical data;

Ground Absorption; and

Source sound power levels.



3.2.1 Meteorological Information

Meteorological information utilised is provided in Table 3-1 and is considered to represent worst-

case conditions for noise propagation. At wind speeds greater than those shown, sound

propagation may be further enhanced, however background noise from the wind itself and from

local vegetation is likely to be elevated and dominate the ambient noise levels.

Table 3-1 Modelling Meteorological Conditions

Parameter Night (1900-0700) Day (0700-1900)

Temperature (oC) 15 20

Humidity (%) 50 50

Wind Speed (m/s) 3 4

Wind Direction* All All

Pasquil Stability Factor F E

* Note that the modelling package used allows for all wind directions to be modelled simultaneously.

It is generally considered that compliance with the assigned noise levels needs to be demonstrated

for 98% of the time, during the day and night periods, for the month of the year in which the worst-

case weather conditions prevail. In most cases, the above conditions occur for more than 2% of the

time and therefore must be satisfied.

3.2.2 Topographical Data and Buildings

Topographical data was based on that publicly available from GoogleEarth in the form of spot

heights as well as project specific data.

In addition, buildings within and surrounding the proposed site were incorporated as these can

provide noise barrier effects and also reflection paths. Buildings on adjacent industrial sites were

modelled at 6 metres high.

The buildings are assumed to be built from corrugated steel sheets at least 1mm thick and internally

lined with acoustic insulation at least 50mm thick to prevent reverberant noise build up. Vents are

also provided on the ridge line of the MRF building roof to allow for natural ventilation with

approximately 100m2 in total open area.

3.2.3 Ground Absorption

Ground absorption varies from a value of 0 to 1, with 0 being for an acoustically reflective ground

(e.g. water or bitumen) and 1 for acoustically absorbent ground (e.g. grass). In this instance, a value

of 0 has been used as an average across the study area.

3.2.4 Source Sound Levels

The sound power levels used in the modelling are provided in Table 3-2.

With regards to the above, please note the following:

The sound power levels represent L10 source levels;

The sound power levels for the excavator were derived from on-site measurements with the

equipment operating under normal conditions and not a static 'idle' condition;

The sound power levels for other equipment were derived from measurements of similar

equipment either already on file or provided by the Client;

All mobile equipment were modelled as a point source located 2 metres above local ground,

with the exception of the forklift, modelled 1m above ground; and,

The conveyors and balers within the MRF building were modelled as line sources located

between 1 and 3 metres above local ground.

3.2.5 Truck movements

A total of 153 trucks per day are expected at the facility during the operating day (0600 to 1830).

The trucks are evenly split between the WTS/MRF (76 trucks) and aggregated commodities (77

trucks) and will also use dedicated entrances.



In relation to the WTS/MRF, trucks will enter and exit via the Alice Street weighbridges. There will

also be two peak-hour periods, each two hours long, during which 28 trucks are expected (14 trucks

per hour).

For the aggregated commodities, the trucks will enter and exit site from Jackson Street.

Assuming only one peak-hour period occurs over the representative assessment period (the RAP) of

4 hours, the worst-case numbers of trucks were estimated at 34 for the MRF/WTS and 25 for the

aggregated commodities over the RAP.

4 RESULTS

4.1 Site Measurements

During our site visit of the 13 April 2016, only the excavator managing the scrap metal stockpile was

operating. A noise level of 78 dB LA10 was recording at 25 metres from the excavator operating and

this level was used as an input in the noise modelling. Figure 4-1 shows the excavator at work.

A second site visit was undertaken to record local ambient noise levels at a location close to the

potentially most affected industrial receiver located at No 6 Alice Street. Noise levels were

continuously recorded over a period of 30 minutes in the morning while normal operations on the

existing site and nearby receivers were occurring. The following noise levels were recorded:

78 dB LAmax from a haul truck on Alice Street;

68 dB LA1; and,

57 dB LA10.

From our observation on site the ambient noise was found to be dominated by heavy goods vehicle

traffic on Alice Street, industrial noise from surrounding industry and sporadic aircraft fly over. It

was also noted the excavator on the proposed site was working behind a stock pile 3 to 4 metres

high and therefore its noise emission was not audible at the monitoring location (refer Figure 4-2).

Figure 4-2 Monitoring Location at Entry Ramp From Alice Street



4.2 Noise Modelling

The results of the noise modelling for the proposed operations are shown as noise level contour

plots in Figures 4-3 and 4-4 for the day (0600 to 1830) and night (1830-0600) operations

respectively, and are also summarised below in Table 4-1.

The day operations (0600 to 1830) include the noise emissions from the WTS and MRF facility, Bale

Shed, truck movements and metal shredder. The new buildings (WTS and MRF, Bale Shed, etc.) are

assumed to be internally lined with acoustic insulation at least 50mm thick to prevent reverberant

noise build up. It is also noted that roller shutter doors are located on the southern west wall of the

WTS and MRF. For the purpose of this assessment, it was assumed two roller doors can be open for

more than 10% of the representative assessment period and therefore noise breaking out through

two open roller doors was included in the model.

In relation to truck movements on site, in particular to/from the MRF/WTS, it was considered the

industrial receiver at 6 Alice Street will be most impacted as this receiver is not shielded by other

buildings and is directly adjacent the Alice Street entry/exit weighbridge. An average route length of

280 metres from the site boundary on Alice Street to the MRF doors (and back out) was derived

from the site plans. Assuming an average truck speed of 20 km/hr, this means truck noise would be

present on site for approximately 28 minutes based on 34 trucks over 4 hours. As such, truck noise

is to comply with the LA10 assigned noise level.

For the night operations (1830 to 0600), only the noise from the MRF and Bale Shed are considered

as other activities will not be occurring at night-time. Noise emissions include the MRF noise

breakout via the roof vents and the open roller door to the Bale Shed, and the forklift noise.

5 ASSESSMENT

5.1 Day Operations - 0600 to 1830

It is noted the shredder shed will be fully open to the north east, therefore allowing for noise to

breakout in this specific direction. Given the relatively short distances to the industrial receiver to

the north east, impulsiveness is likely to be present in the noise emissions when the metal shredder

is operating. In addition, the noise emissions from the trucks would also be considered tonal

however, since the noise from the shredder dominates at all receivers, only the +10 dB penalty for

impulsiveness was added in accordance with Table 2-1.

At the nearest noise sensitive premises, annoying characteristics are not considered to be present

given the separation distance of 600 metres and the number of transport corridors nearby.

Given the proposed hours of operations, the noise emissions from the site will spread across the

various time periods defined in the Regulations e.g. night-time and Sundays and public holidays,

noting that the night-time on Sundays and public holidays technically finishes at 0900.

Table 5-1 assesses the noise levels from the day operations on site at each location against the

relevant assigned noise levels.

Notes: 1. Periods are as defined in Table 2-4. 2. The assigned noise level is as defined in Table 2-4. 3. From Table 4-1. 4. Noise adjusted by +10 dB at industrial receivers for impulsiveness from metal shredder operating.

5.1.1 Residential Receivers

It can be seen from the assessment above the noise emissions from the site would only comply with

the Regulations during the daytime, Monday to Saturday 0700 to 1900 hours. To be able to operate



the shredder during the daytime on Sundays and public holidays, that is between 0900 and 1900

hours, would require a further 5 dB reduction in overall noise levels.

5.1.2 Industrial Premises

In relation to the nearby industrial premises, it can be seen the predicted exceedances are larger

than at the residential receivers and therefore the LA10 assigned noise level at the boundary with

other industrial premises drives the compliance requirements. An overall noise reduction of 20 dB

would be required to achieve compliance. It is noted this level of reduction assumes that noise

emissions from the shredder are impulsive when assessed at the boundary and therefore should

impulsiveness be removed then only an overall reduction of 10 dB is required.

However, it is also noted that should the shredder noise be mitigated, noise from trucks on site can

become a significant noise contributor, in particular at the industrial receiver on the east side of the

entry/exit ramp off Alice Street (No. 6 Alice Street). At that location the predicted truck noise level is

67 dB LA10 (refer Table 4-2). As this noise emission would be considered tonal, a +5 dB penalty must

be added, resulting in an assessable level of 71 dB LA10. Therefore, the noise from the trucks alone

would result in a 6 dB exceedance at the industrial receiver located at No. 6 Alice Street.

5.2 Night Operations - 1830 to 0600

At night-time, no equipment will be operating outdoors and the noise emissions from the Bale Shed

and MRF buildings will be contained within each building. However, the roller door to the Bale Shed

will be in use and, as such, tonality could be present at the closest industrial receiver which is 'Mid-

West', but was not considered likely at all other receivers.

Outside the hours of 0600 to 1830, only the MRF and Bale Shed buildings will continue operating

and given the proposed hours of operations, its noise emissions will spread across all various time

periods defined in the Regulations.

Table 5-2 assesses the noise levels from both buildings at each location and against the relevant

assigned noise levels.

It can be seen from the assessment the noise emissions from night operations can comply with the

Regulations at all times and at all receivers and therefore no noise mitigation would be required.

6 RECOMMENDATIONS

6.1 Day Operations

6.1.1 Industrial Receivers

On the basis the assigned noise levels at the boundary with adjacent industrial premises drive the

compliance requirements, an overall noise reduction of 20 dB is required.

It is noted the most significant noise source is the metal shredder and that it's sound power levels

were derived from sound pressure measurements conducted by others. Therefore it is

recommended to first confirm the selected metal shredder noise levels from manufacturer/supplier

or arrange for measurements to be made of similar shredder on alternative site, with the aim to

identify targeted noise controls to mitigate the shredder noise at the source. Alternatively, the

following noise controls could be used to reduce the impact from the shredder shed noise:

Incorporate localised noise barriers within the shed and around the shredder to provide at

least 10 dB overall noise reduction to the combined metal shredder and excavator noise.

Or,

Close off the open side of the shredder shed when the shredder is in operation. This could

be done using roller doors or large flexible noise curtains which can be open and closed on

demand and relatively quickly.

It is considered that either noise controls above will remove the impulsiveness characteristic and

result in compliance with the Regulations.

It is noted that truck noise would also need to be mitigated by at least 10 dB at the receiver on the

east side of the entry ramp from Alice Street, which could be achieved by building a noise wall along

the east side of the ramp and a section of the north east boundary. It is noted such noise barrier will

also mitigate noise from the shredder shed at that receiver. Alternatively, reducing the number of

trucks entering the site via the Alice Street ramp to 28 in any 4 hours would result in truck noise

being present in that area of the site for approximately 23 minutes. Compliance with the LA1

assigned noise levels of 75 dB would then be achieved even with the tonal penalty included.

Furthermore, if deemed required for reversing alarms to be fitted, all trucks and mobile equipment

are recommended to have broadband noise reversing alarms fitted to minimise the impact of

vehicle reversing noise.

6.1.2 Residential Receivers

Compliance with the Regulations during the daytime, that is Monday to Saturday between 0700 and

1900 hours, can be achieved. However, to operate the shredder during the daytime on Sundays and

public holidays, that is between 0900 and 1900 hours, would require a further 5 dB reduction in

overall noise levels.

This level of reduction is expected to be readily achieved by noise controls implemented to achieve

compliance at the neighbouring industrial receivers.



6.2 Night Operations

The night operations were predicted to comply with the Regulations and therefore no mitigation

measures are required other than ensuring the inside of the buildings are lined with acoustic

insulation at least 50mm thick to prevent reverberant noise build up.

Terminology


The following is an explanation of the terminology used throughout this report.

Decibel (dB)

The decibel is the unit that describes the sound pressure and sound power levels of a noise source. It

is a logarithmic scale referenced to the threshold of hearing.

A-Weighting

An A-weighted noise level has been filtered in such a way as to represent the way in which the human

ear perceives sound. This weighting reflects the fact that the human ear is not as sensitive to lower

frequencies as it is to higher frequencies. An A-weighted sound level is described as LA dB.

Sound Power Level (Lw)

Under normal conditions, a given sound source will radiate the same amount of energy, irrespective of

its surroundings, being the sound power level. This is similar to a 1kW electric heater always radiating

1kW of heat. The sound power level of a noise source cannot be directly measured using a sound level

meter but is calculated based on measured sound pressure levels at known distances. Noise modelling

incorporates source sound power levels as part of the input data.

Sound Pressure Level (Lp)

The sound pressure level of a noise source is dependent upon its surroundings, being influenced by

distance, ground absorption, topography, meteorological conditions etc and is what the human ear

actually hears. Using the electric heater analogy above, the heat will vary depending upon where the

heater is located, just as the sound pressure level will vary depending on the surroundings. Noise

modelling predicts the sound pressure level from the sound power levels taking into account ground

absorption, barrier effects, distance etc.

LASlow

This is the noise level in decibels, obtained using the A frequency weighting and the S time weighting

as specified in AS1259.1-1990. Unless assessing modulation, all measurements use the slow time

weighting characteristic.

LAFast

This is the noise level in decibels, obtained using the A frequency weighting and the F time weighting

as specified in AS1259.1-1990. This is used when assessing the presence of modulation only.

LAPeak

This is the maximum reading in decibels using the A frequency weighting and P time weighting

AS1259.1-1990.

LAmax

An LAmax level is the maximum A-weighted noise level during a particular measurement.

LA1

An LA1 level is the A-weighted noise level which is exceeded for one percent of the measurement

period and is considered to represent the average of the maximum noise levels measured.

LA10

An LA10 level is the A-weighted noise level which is exceeded for 10 percent of the measurement

period and is considered to represent the “intrusive” noise level.


LAeq

The equivalent steady state A-weighted sound level (“equal energy”) in decibels which, in a specified

time period, contains the same acoustic energy as the time-varying level during the same period. It is

considered to represent the “average” noise level.

LA90

An LA90 level is the A-weighted noise level which is exceeded for 90 percent of the measurement

period and is considered to represent the “background” noise level.

One-Third-Octave Band

Means a band of frequencies spanning one-third of an octave and having a centre frequency between

25 Hz and 20 000 Hz inclusive.

LAmax assigned level

Means an assigned level which, measured as a LA Slow value, is not to be exceeded at any time.

LA1 assigned level

Means an assigned level which, measured as a LA Slow value, is not to be exceeded for more than 1% of

the representative assessment period.

LA10 assigned level

Means an assigned level which, measured as a LA Slow value, is not to be exceeded for more than 10% of

the representative assessment period.

Tonal Noise

A tonal noise source can be described as a source that has a distinctive noise emission in one or more

frequencies. An example would be whining or droning. The quantitative definition of tonality is:

the presence in the noise emission of tonal characteristics where the difference between -

(a) the A-weighted sound pressure level in any one-third octave band; and

(b) the arithmetic average of the A-weighted sound pressure levels in the 2 adjacent one-third

octave bands,

is greater than 3 dB when the sound pressure levels are determined as LAeq,T levels where the time

period T is greater than 10% of the representative assessment period, or greater than 8 dB at any time

when the sound pressure levels are determined as LA Slow levels.

This is relatively common in most noise sources.

Modulating Noise

A modulating source is regular, cyclic and audible and is present for at least 10% of the measurement

period. The quantitative definition of modulation is:

a variation in the emission of noise that —

(a) is more than 3 dB LA Fast or is more than 3 dB LA Fast in any one-third octave band;

(b) is present for at least 10% of the representative.


Impulsive Noise

An impulsive noise source has a short-term banging, clunking or explosive sound. The quantitative

definition of impulsiveness is:

a variation in the emission of a noise where the difference between LA peak and LA Max slow is more than 15

dB when determined for a single representative event;

Representative Assessment Period

Means a period of time not less than 15 minutes, and not exceeding four hours, determined by an

inspector or authorised person to be appropriate for the assessment of a noise emission, having

regard to the type and nature of the noise emission.

Background Noise

Background noise or residual noise is the noise level from sources other than the source of concern.

When measuring environmental noise, residual sound is often a problem. One reason is that

regulations often require that the noise from different types of sources be dealt with separately. This

separation, e.g. of traffic noise from industrial noise, is often difficult to accomplish in practice.

Another reason is that the measurements are normally carried out outdoors. Wind-induced noise,

directly on the microphone and indirectly on trees, buildings, etc., may also affect the result. The

character of these noise sources can make it difficult or even impossible to carry out any corrections.

Ambient Noise

Means the level of noise from all sources, including background noise from near and far and the

source of interest.

Specific Noise

Relates to the component of the ambient noise that is of interest. This can be referred to as the noise

of concern or the noise of interest.


Peak Component Particle Velocity (PCPV)

The maximum instantaneous velocity in mm/s of a particle at a point during a given time interval and

in one of the three orthogonal directions (x, y or z) measured as a peak response. Peak velocity is

normally used for the assessment of structural damage from vibration.

Peak Particle Velocity (PPV)


is the vector sum of the PCPV for the x, y and z directions measured as a peak response. Peak velocity

is normally used for the assessment of structural damage from vibration.

RMS Component Particle Velocity (PCPV)


in one of the three orthogonal directions (x, y or z) measured as a root mean square (rms) response.

RMS velocity is normally used for the assessment of human annoyance from vibration.

Peak Particle Velocity (PPV)


is the vector sum of the PCPV for the x, y and z directions measured as a root mean square (rms)

response. RMS velocity is normally used for the assessment of human annoyance from vibration.
