1. INTRODUCTION

Peter Tippett Haulage has commissioned Herring Storer Acoustics to carry out an acousticassessment of its operations, particularly truck movements in and out of the depot, located at484 Bickley Road, Maddington.

Conditional approval has been granted to the haulage company, by the City of Gosnells, with thecondition being for operations only occur Monday to Friday. This acoustic assessment has beenundertaken to support the application to allow trucks to enter and exit the yard on Saturdays.

Whilst the Environmental Protection (Noise) Regulations 1997 do not distinguish a criteriondifference between weekdays and Saturdays, between the hours of 07:00 and 19:00, it is theopinion of the City that ambient noise levels on Saturdays could be less than those on aweekday; hence the truck movement would be more intrusive. Therefore, an “extraordinary”assessment of the Haulage operations has been undertaken to compare the potential truckmovements in and out of the yard on a Saturday. Ambient noise levels were measuredcontinuously over two consecutive Saturdays, as well as weekday’s in-between.

Noise levels measurements of the truck movements in and out of the yard were conducted withthe results from this assessment also being assessed for compliance against the EnvironmentalProtection (Noise) Regulations 1997.

2. SUMMARY

The objective of this assessment was to measure noise levels attributable to the truckmovements in and out of Peter Tippett Haulages yard and assess against the regulatory criteria.Additionally, comparisons of a Saturday with and without the truck movements have also beenconducted.

Noise levels for truck movements associated Peter Tippett Haulage, at the nearest residentialpremises, has been calculated to be 47 dB(A). This can be compared to the assigned noise levelof 66 dB(A) for weekdays and Saturdays. Hence compliance with the Environmental Protection(Noise) Regulations 1997 is achieved at all times.

The comparison of noise levels for Saturdays shows that truck noise associated with the haulageoperations would not be distinguishable from other traffic noise associated with vehiclestravelling on Kenwick and Bickley Roads; and ambient noise levels are similar to that whichoccur on a weekday hence, would not be any more intrusive. Based on the analysis undertaken,the haulage yard should be able to expand its operations to include Saturdays.

3. CRITERIA

The acoustic criteria are as required in the Environmental Protection (Noise) Regulations 1997. These regulations stipulate maximum allowable external noise levels determined by the calculation of an influencing factor, which is then added to the base levels shown in Table 3.1. The influencing factor is calculated for the usage of land within the two circles, having radii of 100m and 450m from the premises of concern.

LA1 is the noise level exceeded for 1% of the time. LAmax is the maximum noise level. IF is the influencing factor.

It is a requirement that noise from the site, when received at another premises, be free of annoying characteristics (tonality, modulation and impulsiveness), defined below as per Regulation 9.

“impulsiveness” means a variation in the emission of a noise where the difference between LApeak and LAmax Slow is more than 15 dB when determined for a single representative event;

“modulation” means a variation in the emission of noise that –

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

(b) is present for more at least 10% of the representative assessment period; and

(c) is regular, cyclic and audible;

“tonality” means 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 3dB 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 8dB at any time when the sound pressure levels are determined as LA Slow levels.

If the above characteristics exist and cannot be practicably removed, then any measured level is adjusted according to Table 3.2 below.

TABLE 3.2 - ADJUSTMENTS TO MEASURED LEVELS

Where tonality is present Where modulation is present Where impulsiveness is present

+5 dB(A) +5 dB(A) +10 dB(A)

Note: These adjustments are cumulative to a maximum of 15 dB.



Our Ref: 18925-1-15046

The nearest potential noise sensitive premises to the Haulage operations has been identified using the area map in Figure A2 in Appendix A. Zoning for the area has been based on the City of Gosnells Zoning Map shown in Figure 1.

FIGURE 1 – ZONING MAP

The influencing factor at the closest identified noise sensitive premises has been assessed, with the calculation based on the following:

Industrial within inner circle 39% +3.9 dB

Industrial within outer circle

75% +7.5 dB

Total IF 11.4 dB (Rounded down to 11 dB)

4. METHODOLOGY

Noise imissions1, due to noise associated with truck movement in and out of the yard, weremeasured during a site visit on Saturday 21st February 2015.

Hand held, observed measurements were conducted (close to the front gate, nearest the truckpass) for a Volvo truck exiting and entering the yard twice. Measurements were conducted ofthe entire pass by event which takes approximately 30 seconds from mid yard to Kenwick Road(including the access road).

Continuous noise monitoring was also conducted from Friday 20th February, through to Tuesday3rd March. The logger was situated near to the access drive of the haulage operations, on BickleyRoad, with photos shown below.

Figure 1 – Monitoring Photographs

5. RESULTS

The measured noise levels from both the hand held measurements of the truck passes, and a comparison of the two Saturdays are shown below. Additional graphs for the entire period are contained in Appendix B.

The entering and exiting of the yard by trucks, for the purpose of testing occurred at 09:15 on Saturday the 20th February. These times have been highlight on the graph. It should be noted that the second Saturday, the 28th February was a long weekend; hence there may have been some altered conditions from a normal Saturdays.

Noise levels have been presented in one minute increments to ensure clarity.

It should also be noted that the only truck movements associated with the haulage yard on either Saturday were those truck measurements undertaken for testing.

Figure 2 – Saturday Comparison (Continuous Noise Monitor)

Assessment of the time taken for the truck to pass into the yard from Kenwick road, resulted in the noise level being present for less than 10% of the time. Therefore, the appropriate parameter is the LA1 noise level. Based on this, the measure noise level was LA1 64dB(A). As this was measured on the access road, within 2 to 5m of the passing truck (location shown in Appendix A), calculations were undertaken to allow for the further distance of the residence have been made. Conservatively, the attenuation from the measurement point to the nearest residence is 17 dB(A), based on a distance of 35 metres.



Our Ref: 18925-1-15046

6. ASSESSMENT

The applicable adjustments to the calculated noise levels, in accordance with the EnvironmentalProtection (Noise) Regulations 1997, are listed in Table 6.1. Based on calculated noise levelsrelative to the measured ambient noise level, at the nearest noise sensitive premises, noiselevels are not likely to contain “annoying” characteristics in accordance with the EnvironmentalProtection (Noise) Regulations 1997.

Hence, Table 6.1 summarises the applicable Assigned Noise Levels, and assessable noise levelemissions.

7. CONCLUSION

The objective of this assessment was to measure noise levels attributable to the truckmovements in and out of Peter Tippett Haulages yard and assess against the regulatorycriteria. Additionally, comparisons of a Saturday with and without the truck movements havealso been conducted.

Noise levels for truck movements associated Peter Tippett Haulage, at the nearest residentialpremises, has been calculated to be 47 dB(A). This can be compared to the assigned noise levelof 66 dB(A) for weekdays and Saturdays. Hence compliance with the Environmental Protection(Noise) Regulations 1997 is achieved at all times.

As to the comparison of noise levels for Saturdays, the monitoring shows that the truck noiseassociated with the haulage operations would not be distinguishable from other traffic noises,such as vehicles travelling on Kenwick and Bickley Roads and the ambient noise levels on aSaturday are similar to that received on a weekday.

Based on the above, the haulage yard should be able to extend its operations to includeSaturday.
