1 INTRODUCTION This report assesses the potential noise impacts from a proposed service station (and associated retail) at Lot 9000 Bussell Highway in Margaret River to existing and proposed residences. The planned local centre, comprising the service station, is shown in Figure 1-1 comprising the store, diesel refuelling area and carwash facilities.

Existing residences are located on Village Green to the north (left of page). Land to the east of the service station site (between the proposed local centre and Beech Drive) will be subdivided into R40 residential lots.

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".

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

Table 2-l Adjustments for Intrusive Characteristics

Modulation ‘

impulsiveness

+ 5dB ‘

+ 5dB ‘

+ 10dB

Note" The above are cumulative to a maximum 0f15dB.

The baseline assigned levels (prescribed standards) are specified in Regulation 8 and are shown in Table 2-2.

The influencing factor, applicable at the noise sensitive premises has been calculated as 3 dB, as a result of 2 dB from Bussell Highway (secondary road within 100m) and 1 dB due to the proposed local centre (service station/retail) considered as 'commercial’ in Schedule 1 Classification of Premises of the Regulations.

Table 2-3 shows the assigned noise levels including the influencing factor.

The assigned noise levels apply outside a residence and as such, this is what must be satisfied for the existing residences. For the residences proposed as part of this development, there is an opportunity to enforce higher than standard construction requirements for the dwellings so that internal noise levels are acceptable, even though external noise levels may be above the assigned levels.


Lloyd George ACOUSTICS

A critical period will be Sunday's during the daytime where mechanical plant and carwash activities are likely to operate for more than 10% of the time. As such, the LA10 assigned noise level of 43 dB is applicable.

The other critical period will be during the night. At this time, there is expected to be low usage of the carwash but could potentially be a refrigerated truck refuelling. In both instances, the noise may be present for more than 1% of the time but less than 10% of the time and as such, the LA1 assigned noise level of 38 dB is applicable.

Note that noise from vehicles engines are not assessed as these are considered exempt by way of regulation 3(1)(a). However, noise from the refrigeration units on refrigerated trucks is considered.

3 METHODOLOGY To predict the noise emissions from the site to neighbouring residences, the software $0undPLAN 7.2, with the CONCAWE algorithms, has been utilised. 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.

3.1 MeleorologicolInformation

Meteorological information utilised (Table 3-1) is based on that specified in the draft EPA Guidance for the Assessment of Environmental Factors No.8 Environmental Noise. These conditions are considered the worst-case 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.

Note that the modelllrlg package useo allows roi all Wlfld dlretllons to be modelled simultaneously


Lloyd George Acousiics

The EPA policy is 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 Topographical Dala

Topographical data was based on that shown on the site plan and elevations, including the site being somewhat cut into the existing topography.

3.3 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). The site itself (excluding landscaping area) has been assumed to have a value of 0.1, with 1.0 used elsewhere.

3.4 Source Sound Levels

Table 3-2 presents typical sound power levels appropriate for service station noise assessments.

3.5 Scenarios

The scenarios modelled are:

Sunday being 43 dB Lm.

2. Auto Carwash Operating with 1 x self serve bays and 1 x vacuum as well as a refrigerated truck at the diesel refuelling area. This is considered to represent a worst-case night-time scenario. This scenario is unlikely to occur often, but may occur at night and is therefore compared to the night LA1 assigned level of 48 dB LA1.

3. Auto Carwash Operating with 4 x self serve bays and 4 x vacuums as well as a refrigerated truck at the diesel refuelling area. This is considered to represent a rare daytime scenario and is therefore assessed against the Sunday LA1 assigned noise level of 53 dB LA1.

4 RESULTS The results for the noise modelling to the existing residences is summarised below in Table 4-1.

During the day, the exceedance is calculated to be up to 11 dB LAN and 4 dB LA1, whilst during the night, the exceedance is calculated to be up to 9 dB LA1. The noise levels at each house varies significantly, depending on the shielding provided by the retail building.

It is common practice for automatic car washes to have entry and exit doors installed which close prior to the car wash commencing operation. These doors are capable of providing up to around 22 dB reduction depending on the model of door selected. For the purpose of this assessment, it

has been assumed a reasonably high performance door will be installed, sufficient to achieve a 15 dB reduction. Installing such doors, results in noise levels reducing to a worst-case of 44 dB LA“, at existing residences and therefore still an exceedance of 1 dB.

To accommodate this further reduction and provide improved amenity, it is recommended the boundary wall to the perimeter of the site be 2 metres high. For consistency, this is to apply alongside the existing residences and the proposed residences. For the existing residences (25 to 33 Village Green), the existing fence is timber pine lap. As such fencing can warp over time, this is not adequate as an acoustic wall. As such, this fence is to be replaced with a noise wall or an additional wall is to be constructed. Walls are to be free of gaps and constructed of a material having a

minimum surface mass of 15kg/ml. An alternative to a wall would be to construct a bund or bund and wall combination within the perimeter landscaping area.

With the above controls in place, noise reductions also occur for the LA1 predicted noise level. As both LA1 scenarios are dominated by the refrigerated truck, both result in the same predicted noise level of up to 52 dB LA1, being a worst case exceedance of 4 dB during the night. To achieve this reduction requires the north side of diesel refuelling area to be enclosed. This could be Colorbond sheeting if desired, with the truck side of the sheeting to be lined with insulation such as 50mm thick, Z4 kg/m3 with a perforated foil facing.

With the described noise controls in place, compliance is achieved at the existing residences.



Noise levels at the proposed residences are calculated to be up to 58 dB LAN during the day and 63 dB LA1 during the day and night due to a refrigeration truck. These represent exceedances of up to 15 dB LAN and 15 dB LA1. As these proposed residences form part of the same structure plan application, it is possible to place restrictions on the development. Recommended requirements are:

' Notifications on title to advise of the close proximity of the service station (and supporting retail) and the potential for high levels of noise.

' Each dwelling is to provide at least one outdoor area that is shielded from the service station by either locating on the east side of the dwelling or constructing an alcove type arrangement so that the outdoor area is again, protected by the dwelling. The focus is to be not having line of site to the refuelling area or carwash area.

' Locate, where practicable, non-habitable rooms on the west side of the dwelling to face the service station/retail use.

' Eaves are to be enclosed with minimum 4mm thick fibre cement sheet. ' Ceiling to be insulated with minimum R3 type insulation between ceilingjoists. ' Roof to be Colorbond with Anticon or clay rooftiles with sarking. ' Ceilings to be 13mm thick plasterboard. ' Walls to be double brick construction. ' Windows to bedrooms on the west, north or south sides to be no more than 20% of the

floor area, fixed, awning or casement style with 10.38mm thick glass sufficient to achieve Rw 35.

' Windows to other habitable spaces (including kitchens) on the west, north or south sides to be no more than 50% of the floor area, fixed, awning or casement style with 10.38mm thick glass sufficient to achieve RW 35.

' Mechanical ventilation to be provided to allow windows to be closed.

5 NOISE MANAGEMENT From the analysis within this report, the following recommendations are made:

' Boundary wall is to be constructed around the perimeter of the site at a minimum height of 2 metres. The wall is not to have any gaps and be constructed of a material having a

minimum surface mass of 15kg/ml such as brick, limestone, twinside panels or other equivalent.

' Automatic carwash is to have entry and exit doors installed. These doors are to close prior to operation of the carwash and be sufficient to provide a minimum 15 dB insertion loss.

' North side of the diesel refuelling area is to be sheeted with Colorbond or similar with 50mm thick, 24kg/ma insulation to the inside of the Colorbond. The insulation can be faced with perforated foil or similar.



New residences, immediately to the east of the site, are to have the following restrictions/requirements:

o Notifications on title to advise of the close proximity of the service station (and supporting retail) and the potential for high levels of noise.

Each dwelling is to provide at least one outdoor area that is shielded from the service station by either locating on the east side of the dwelling or constructing an alcove type arrangement so that the outdoor area is again, protected by the dwelling. The focus is to be not having line of site to the refuelling area or carwash area.

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 {L,,,) 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 lkW 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 (L,,) 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.

I-ASlow

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.

I-AFust

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.

I-AP2ak

This is the maximum reading in decibels using the A frequency weighting and P time weighting AS1259.1-1990.

I-Amnx

An LAM“ level is the maximum A—weighted noise level during a particular measurement.

I-A1

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.

I-A10

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.

Reference: 13042396-03.docx Page A 1


I-Aeq

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.

I-A90

An l-AQQ 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.

LA,,,,,,, assigned level Means an assigned level which, measured as a LA5|°W value, is not to be exceeded at any time.

LA; assigned level Means an assigned level which, measured as a LA5|Ow value, is not to be exceeded for more than 1% of the representative assessment period.

LAM assigned level Means an assigned level which, measured as a LA5k,W 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;|,,w 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 LAM or is more than 3 dB LAW, 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 LAW“ and LA Mamow is more than 15 dB when determined for a single representative event;

Major Road ls a road with an estimated average daily traffic count of more than 15,000 vehicles.

Secondary / Minor Road ls a road with an estimated average daily traffic count of between 6,000 and 15,000 vehicles.

Influencing Factor {IF} = £ (U/° TY!” A100 + 0/" TYPE A450 )‘l' % (0/° Type B100 + % TYPe B450) where :

% Type Am = the percentage of industrial land within al00m radius of the premises receiving the noise

%TypeA45o = the percentage of industrial land within a 450m radius of the premises receiving the noise

% Type B100 = the percentage of commercial land within al00m radius of the premises receiving the noise

%TypeB,,5(, = the percentage of commercial land within a 450m radius of the premises receiving the noise

+ Traffic Factor (maximum of 6 dB) = 2 for each secondary road within 100m = 2 for each major road within 450111 = 6 for each major road within 100m

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 ofinterest.

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) The maximum instantaneous velocity in mm/s of a particle at a point during a given time interval and 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) 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 root mean square (rms) response. RMS velocity is normally used for the assessment of human annoyance from vibration.

Peak Particle Velocity (PPV) The maximum instantaneous velocity in mm/s of a particle at a point during a given time interval and 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.
