Attachment 5 - Environmental Noise Assessment

Executive Summary
EcoAcoustics Pty Ltd was commissioned by Kings Group to conduct a noise impact assessment of a
proposed car wash and take-away coffee shop located at 34 Elm Street Cooroy. This noise impact
assessment report has been completed to support the proposal, as part of the development
application. The purpose of this report is to assess the noise emissions from the site in accordance
with the prescribed standards contained in the Environmental Protection (Noise) Policy 2008.
To ensure compliance with the EPP (Noise), the following recommendations are required to be
incorporated into the proposed carwash:
    ➢ All vacuum bays are required to be three-phase vacuums;
    ➢ The plant room roof is to be lined with 50mm 32kg/m3 sound absorbing insulation or
      similar ;
    ➢ The proposed automatic car wash bays will be fitted with automatic doors on the exit
      equivalent to a PVC clear 2.5 mm door blade (which provides a minimum Rw 23);
    ➢ The entry to the automatic wash bays will be fitted with a roof as shown in Figures 1.2 and
      1.3;
    ➢ Vacuum bays are not permitted to operate during the night time period.
The results of the noise predictions show that the site can comply with the noise criteria set out in
EPP (Noise) for all time periods at nearby residential receivers with the inclusion of the attenuation
measures discussed in Section 6.
