1   INTRODUCTION

BP Australia Pty Ltd (BP) are proposing to refurbish an existing service station located at
210 (Lot 151) Great Eastern Highway in Ascot, on the corner of Resolution Drive – refer
Figure 1.1 taken from the City of Belmont’s Local Planning Scheme No.14. The main area
of interest of this report is the addition of an automotive vehicle wash, although analysis has
also been undertaken of some existing noise sources.


                R1 – 27 Hardey Rd                                   R2 – 16 Carbine St


                                                                                 R3 – 214 GEH




                                                                                    R4 – 249 GEH

        Proposed Facility




                                    Figure 1.1 –Locality Map

Noise from the facility has been assessed to the closest residences (refer Figure 1.1) against
the prescribed standards of the Environmental Protection (Noise) Regulations 1997.

Note that an acoustic assessment has already been undertaken by another consultant and
submitted to the City of Belmont. However, the Council have requested an independent
acoustic assessment to ensure compliance can be achieved.

Appendix E 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

                                                                                                                          A
                                                                                            Lloyd George Acoustics
                                                                                                                         59
             (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 5dB 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 2.1 – Adjustments For Intrusive Characteristics

                            Tonality                       Modulation                       Impulsiveness

                              + 5dB                          + 5dB                               + 10dB

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

The baseline assigned levels (prescribed standards) are specified in Regulation 8 and are
shown below in Table 2.2.

The influencing factor has been calculated at each receiver location. Note that R3 is
currently commercial and therefore has no influencing factor with allowable levels of 60 dB
LA10, 75 dB LA1 and 80 dB LAmax. Table 2.3 shows the applicable influencing factor should
the site be developed into residential.

With reference to Section 4, it has been determined that the most critical assigned noise
levels are the LA10 on Sundays during the day and the LA1 during the night. The LAmax is also
applicable for the intermittent audible alarm from the air pressurisation units used for tyre
inflation.

Table 2.4 shows the critical assigned noise levels including the influencing factor at each of
the assessment locations.

Numbers in brackets indicate assigned noise level if residential use.



3     CARWASH USAGE

From Table 2.2, it can be seen that for items that do not operate for more than 10% of the
time, a higher allowable noise level is permissible. That is, if something generates noise for
more than 1% but less than 10% of the time, the LA1 parameter is applicable. Similarly if
something operates for less than 1% of the time, the LAmax parameter is applicable.

Information sourced for previous projects indicated that a car wash will be used 34.5%
during the day on a Sunday and 3.2% of the night on a Sunday. All other days/times
resulted in lower percentage uses and thus Sunday is the most critical. Note that vacuum
usage is assumed to be equivalent with carwash usage.

Due to the relative low usage of the car wash at night, it is considered unlikely the vacuum
units would operate simultaneously with the carwash and hence these are assessed
independently. During the day or evening, it is considered possible that the carwash and
vacuums will operate simultaneously.

Noise from the audible alarm associated with the air pressurisation device is present for only
a short time, considered to be less than 1% and therefore the night LAmax parameter is
applicable.

4    METHODOLOGY

4.1 Site Measurements
Long term monitoring has been undertaken at R4 as part of a different project. This
monitoring involved the use of an ARL Type 316 noise data logger and was located 5 metres
from Great Eastern Highway. The logger was programmed to record hourly LA1, LA10, LA90,
and LAeq levels. The logger was field calibrated before and after the measurement session
and found to be accurate to within +/- 1 dB. Lloyd George Acoustics also holds current
laboratory calibration certificate for the loggers.

Hand held noise measurements were undertaken of the equipment (existing and proposed)
on 25 March 2010. The proposed carwash was measured at BP Carlisle (corner of Orrong
Road and Archer Street), whilst the vacuum and tyre pressurisation alarm were both
measured at the Ascot side.

Measurements were undertaken in accordance with Regulations 19, 20, 22 and 23 and
Schedule 4, specifically noting the following:

        The sound level meter used was a Bruel & Kjaer Type 2260 (S/N: 2508199), which
        holds current laboratory certificates of calibration (Calibration Date 4 July 2007)
        available upon request and was field calibrated before and after the measurements
        and found to be within +/- 0.5 dB. This meter simultaneously records the slow and
        fast time weighted sound levels allowing relevant data to be collected. The
        microphone was fitted with a standard wind screen with winds being less than 5m/s;

        The microphone was at least 1.2 metres above ground level and at least 3.0 metres
        from reflecting facades (other than the ground plane) and as such no adjustments
        have been applied for reflected noise;

4.2 Noise Modelling
To determine the noise emissions from the automotive vehicle wash facility, the computer
modelling programme SoundPlan 6.5 has been utilised. The programme was selected to
use the CONCAWE algorithms, which requires the following input data:

        Meteorological Information;
        Topographical data;
        Ground Absorption; and
        Source sound power levels.

    4.2.1   Meteorological Information

Meteorological information utilised is based on that specified in EPA Guidance for the
Assessment of Environmental Factors No.8 Environmental Noise draft, and are shown below
in Table 4.1.

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

Note that the above conditions approximate the typical worst-case for enhancement of
sound propagation. 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.

At wind speeds greater than those shown above, sound propagation may be further
enhanced, however background noise from the wind itself is likely to be elevated and
dominate the ambient noise levels.

    4.2.2     Topographical Data

Topographical data was based on file data, which is from the Department of Land
Information (DLI). The contours are in 1-metre intervals and cover the noise sensitive
premises of concern.

Buildings and perimeter fencing have also been included as these can provide barrier
attenuation when located between a source and receiver, much the same as a hill.

    4.2.3     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). The site
itself is considered to be reflective so an absorption of 0.1 (10%) has been assumed, with
the surrounding land assumed to be 0.65 (65%), representing a mixture of hard and soft.

    4.2.4     Sound Power Data

Measurements were undertaken of the BP Carlisle carwash for a deluxe carwash and
standard carwash. The noise levels were logged in 1-second intervals at 3-metres from the
entry door. The entry and exit to the carwash are fitted with acoustic doors that close once
the wash commences. The results of the noise logging are presented in Appendix B. The
LA10 and LA1 noise levels from the carwash were then determined and converted to a sound
power level. Note that the entry and exit doors are assumed to have the same sound power
level as shown below in Table 4.2.

                                                                                                     A
                                                                           Lloyd George Acoustics
                                                                                                    64
During the day on a Sunday, the carwash may operate once every 15-minutes. Based on
this usage, the calculated sound pressure level at 3-metres was 76 dB LA10, with negligible
difference between the standard and deluxe wash cycles. During the night, the usage may
be once every 2-hours. Based on this usage, the calculated sound pressure level at 3-
metres was 77 dB LA1, again with negligible difference between the standard and deluxe
wash cycles.

The vacuum and tyre pressurisation alarms were both measured at the existing Ascot site at
1-metre from each source with the logging results presented in Appendices C & D
respectively.

The vacuum usage is assumed to be on a 1 for 1 basis with the car wash. As such, the
calculated sound pressure level at 1-metre was 84 dB LA10 when assessed over a 15-minute
period (e.g. daytime) and 84 dB LA1 when assessed over a 2-hour period (e.g. night-time).

The highest noise level recorded from the tyre pressurisation alarm was 81 dB LAmax at 1-
metre.

5    RESULTS

5.1 Background Noise Measurements
Figure 5.1 shows the noise levels over an entire Sunday. The measurement location is at 5-
metres from the edge of Great Eastern Highway and is therefore significantly influenced by
road traffic. The lowest noise level is at 4am when road traffic is at a minimum, recording a
noise level of 46 dB LA90. During the day, the noise level is continually around 60 dB LA90.

For every doubling of distance away from the road, a 3 dB reduction would be approximately
applicable.

6   ASSESSMENT

Noise levels from each of the noise sources have the potential to contain intrusive
characteristics, in particular tonality. However, if compliance is achieved, that is the noise
levels from the service station is equal to the assigned noise levels, it is unlikely that any
intrusive characteristics would be audible above background noise. As such, no penalty has
been applied for intrusive characteristics.

6.1 Existing Service Station

Examining the existing scenario (Table 5.1), compliance is currently being achieved. The
most critical location is R2, where the predicted noise level from the vacuum unit during the
day is the same as the assigned noise level.

If location R3 was redeveloped for residential use, compliance would be achieved at ground
level. However, the noise levels from the vacuum units are calculated to be 5 dB higher at
an upper floor and would therefore exceed. This could however be readily overcome by
considering this in the design of the residences. It is unlikely that a development would have
balconies for instance facing the service station so external noise at an upper level is
unlikely to a concern. Any windows facing the service station would likely be relatively small
and thicker than standard glass to minimise the impact of road traffic noise.

6.2 Existing Service Station with Car Wash

With the addition of the car wash, noise levels are calculated to exceed the prescribed
standards of the Environmental Protection (Noise) Regulations 1997, based on the car wash
measured at BP Carlisle.

Noise levels from the vacuum and tyre pressurisation alarm comply by themselves, however
the noise of the vacuum units does significantly contribute at some locations.

At R4, it is considered that compliance is achieved at all times, given the only exceedance is
by 1 dB during the day.

At R1 and R2, the car wash is calculated to cause exceedances during the day and night, by
up to 8 dB. Even at R3, a 3 dB exceedance is calculated during the day assuming this is a
commercial property.


7   RECOMMENDATIONS

Based on the methodology and analysis described in this report, the proposed automotive
carwash is calculated to exceed the Sunday LA10 day time assigned noise levels by up to
8 dB and the night-time LA1 assigned noise levels by up to 3 dB. It is therefore
recommended that further noise controls be implemented than those currently proposed.

                                                                                     Lloyd George Acoustics
                                                                                                                 68
In terms of the measured carwash in Carlisle, this did incorporate acoustic doors. Compared
with file data for a typical car wash with no acoustic doors, the Carlisle carwash was around
7 dB less. This would relate to doors that have an Rw1 rating of around 13. From file
information, ratings of up to Rw 26 are available for car wash doors. To achieve compliance
at R1 & R2, an Rw 26 door would be required to the carwash entry. This will result in noise
from the carwash being 5 dB less than the assigned noise level, thereby allowing for the
contribution of the vacuum unit should the two operate simultaneously during the day. An
alternative would be to reduce the rating of the entry door to say Rw 21 and replace the
vacuum units with quieter models. File data suggests models that are up to 15 dB quieter
than those currently present are available. Note that whilst the adjoining lot is commercial,
the exit door is less critical and would need to be improved by only 3 dB (i.e. an Rw 17 rated
door).

A further alternative may be to relocate the carwash. From an acoustic perspective, the
preferred location would be to be orientated parallel to Great Eastern Highway and on the
south side of the parking area where the vacuums are located. This would need to be
assessed in detail on its own merit if it is practicable from a traffic arrangement point of view.

Based on the proposed arrangement, the most practicable noise control options are
considered to be:
      1. Replace the existing vacuum units with quieter models; and
      2. Upgrade the entry door to a minimum Rw 21 rated door; and
      3. Upgrade the exit door to a minimum Rw 17 rated door.

Note that the above recommendations assume the adjoining property to the east remains as
a commercial use. If this property were to be developed as single storey residential, noise
levels are calculated to exceed by up to 15 dB. In this case, the following would be required:
      1. Replace the existing vacuum units with quieter models; and
      2. Install Rw 26 rated doors at both the entry and exit; and
      3. Increase the height of the boundary wall from 1.8 metres to 2.1 metres.

If the neighbouring property were to be developed to multi-storey residential, noise levels at
Level 1 would exceed by up to 19 dB. With the inclusion of Rw 26 rated acoustic doors, the
exceedance would still be 6 dB and therefore the boundary wall would need to increase to
3.5 metres or Level 1 of the development would need to incorporate design features to
minimise noise intrusion (e.g. no balconies facing service station, 10mm laminated glass to
windows etc).

    Rw is a single number value given to a material providing guidance on its sound insulation performance and
measured in a laboratory under controlled conditions. It is determined by using the procedures documented in
AS/NZS 1276 and AS 1191. The higher the number, the better the performance. Note it is very similar to the
previously used STC (Sound Transmission Class) value. The only difference being a shift in frequency range
where Rw is determined from the transmission loss at each one-third-octave band centre frequency between 100
Hz and 3.15kHz, STC was between 125 Hz and 4kHz. The two ratings are normally within 1 point of each other.

If the neighbouring development was to be more than 2 storeys, a boundary wall of say 4
metres high (considered to be the maximum practicable) would not reduce noise levels. As
such, floors above Level 1 would need to incorporate noise mitigation design features and
the carwash would need the highest rated acoustic doors (Rw 26).
