Re: Addendum to Noise Impact Assessment Report - (Noosa Council Decision Notice MCU19/0089)
      Review of Potential Extended Trading Hours for Service Station at 52 & 54 Mary Street,
      Noosaville                                                                   L35721/BH/18-130



MWA Environmental has reviewed the approved noise report and identified the
following relevant matters:

    1. The noise limit applied in the approved noise report for the night period (10pm
       to 7am) was based upon ‘background plus excess’ amenity criteria.
    2. The background noise levels used to derive noise limits for the ‘night’ period
       were assessed over the full 10pm to 7am period, as the Rating Background
       Level. The Rating Background Level parameter is the median of the quietest
       1 hour periods during the 10pm to 7am on each monitoring day. Thus, the
       Rating Background Levels reflect the quieter ‘middle of the night’ period
       background noise levels.
    3. The adopted background noise level for the night was quite low (30 dB(A)), as
       expected between 12am and 4am but conservatively low for the period from
       4am to 7am. The charts included as Figure 3.1 and Figure 3.2 of the approved
       noise report indicate higher background noise levels from 4am.
    4. The ‘middle of the night’ background noise levels were applied in the approved
       noise report to derive noise criteria for the 5am to 7am period.
    5. The ‘sleep disturbance’ noise limit applied in the approved noise report is
       relevant to the full 10pm to 7am period.
    6. The same noise limits would have been applied for the 4am to 5am
       period if those hours were originally proposed and assessed in the
       approved noise report.
    7. The approved noise report indicated compliance with the night noise
       limits and would thus have supported compliance for trading from 4am if
       that were to have been originally proposed.
    8. The noise control recommendations of the approved noise report,
       including acoustic barriers, would not have changed if trading from 4am
       were to have been originally proposed.

On this basis, it is evident that the assessment provided in the approved noise
report supports operation of the service station from 4am to 10pm.

It is considered reasonable for Wessel Petroleum Pty Ltd to seek amendment of
Condition 5 of the Decision Notice to allow extended trading hours, as follows:

        “5. The approved use must not operate outside the hours of 4am to 10pm.”

No other conditions of the Decision Notice require amendment to support the
proposed change to Condition 5.


Yours sincerely
