           methodology) are explained in Section 7.1. In summary, component LAeq noise from refrigeration
           plant on trucks loading / unloading at the commercial site during stipulated loading times, when
           predicted     at the nearest     residences, should         not exceed    the    existing LAeq   noise levels at the

           residential   areas    during that time. The existing noise levels applicable at the residential areas
           near the commercial site are indicated              in the logging results (please refer to Figure 5 to Figure 12

           attached at the end of the report).



           The    quasi-continuous       noise limits     are   presented   in Table   5.     Similar to the transient noise

           emissions, an adjustment of 2dBA has been made for quasi-continuous noise emissions.

7.3        Limits of mechanical plant noise


           In   determining      the   appropriate     noise emission      limits for continuous mechanical          plant noise,
           reference     has   been     made     to    the    Environmental   Protection     (Noise) Policy      2008    and    the

          Environmental Protection Act 1994.



           For continuous noise, the acoustic quality objectives for outdoors as presented in Table 3 would

          apply at all noise sensitive receptors. In addition to these long-term goals, controlling background

          creep must be achieved           as   described in Section 10 of the EPP (Noise). To the extent that it is

           reasonable to do so, noise from an activity must not be:

                   a)      For noise that is continuous and measured           using the LA90, Tll parameter, more than nil
                           dBA greater than the existing acoustic environment measured by the LA90, T; or


                   b)      For noise that varies over time measured            by LAeq, adj, T more than 5dBA greater than
                           the existing acoustic environment measured by LA90, T.


          For air-conditioning equipment, Section 440U of the Act states that an occupier of a premises (at

          or    for which there is air-conditioning equipment) must not use, or permit the use of, equipment

          on    any day:


                   a)      Before 7am, if it makes a noise of more than 3dBA above the background level; or


                   b)      From 7am to      10pm, if it makes a noise of more than 5dBA above the background

                           level; or

                   c)      After 10pm, if it makes a noise of more than 3dBA above the background level.

     This criterion is impossible to achieve, as any additional noise, no matter how small, will result in an increase of the
     LA90, T noise level. Since it is impossible to fulfil the specified requirement, the statement has been re-interpreted to
     mean that the component noise levels due to the continuous noise must be equal to or less than the existing

     ambient LA90 noise level.
