Environmental Noise Level Impact Assessment of Metal Fabrication Business, 54 Boronia Road, Cootharaba      Page 9 of 16




From monitoring location B these noise levels (ambient noise levels less 10 dB(A)) would be:

     •   42 dB(A) LAeq,15min;
     •   54 dB(A) LA1,15min;
     •   44 dB(A) LA10,15min.

The source noise levels measured 15 metres from the eastern end of the Allstar Metal Fabrication
building were adjusted by separation distance to be equivalent to the closest eastern boundary of the
subject site, resulting in the following source noise levels at the closest part of the eastern boundary:

    •    29 dB(A) LAeq,15min;
    •    35 dB(A) LA1,15min;
    •    31 dB(A) LA10,15min.

As all of the above source noise levels, at the closest boundary to the eastern end of the Allstar Metal
Fabrication building, are less than the ambient noise levels less 10 dB(A), it is concluded that noise from
Allstar Metal Fabrication would be inaudible at the closest eastern boundary and, therefore, comply with
the requirements of the Noosa Plan.

At the closest part of the western side boundary of the subject site to Allstar Metal Fabrication the
source noise levels would be:

    •    43.6 – 5.5 = 38 dB(A) LAeq,15min;
    •    49.8 – 5.5 = 44 dB(A) LA1,15min;
    •    45.8 – 5.5 = 40 dB(A) LA10,15min.

As all of the above source noise levels, at the closest boundary to the western end of the Allstar Metal
Fabrication building, are less than the ambient noise levels less 10 dB(A), it is concluded that noise from
Allstar Metal Fabrication would be inaudible at the closest western boundary and, therefore, comply with
the requirements of the Noosa Plan.

On this basis noise from Allstar Metal Fabrication complies with the noise criteria at the closest
boundaries to the Allstar Metal Fabrication building and, therefore, no further noise control measures
are required. This is provided that the shipping container remains in place across the eastern end of the
Allstar Metal Fabrication building.


RECOMMENDATION

It is recommended that, from an environmental noise perspective, Allstar Metal Fabrication be approved
to operate during the daytime only, 0700 to 1800 hours, 6 days per week (Monday to Saturday) but
excluding public holidays, from 54 Boronia Road, Cootharaba, with no further noise control measures
required.
