         For refrigeration equipment, Section 440V of the Act states that an occupier of a premises (at or

         for which there is refrigeration equipment) or an owner of refrigeration 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      lOpm, if it makes a noise of more than SdBA above the background

                              level; or

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



         The above limits apply to air conditioning equipment and                 refrigeration equipment that would be
         installed within the proposed commercial development site. We note that there is possibility that a

         supermarket could be developed at the site, which could result in refrigeration plant operating
         continuously for 24-hours. Therefore noise emission limits should be determined for day, evening
         and night time periods.



         The Act does not specify the noise measurement parameter which is represented                          by the default
         noise standard limits. When                measuring continuous noise from mechanical plant, the parameter
         which is usually used is the LAeq noise level.




    The LA90 noise levels associated with the existing acoustic environment are presented in Table 1 and

        Table 2. From these levels, the corresponding limits for mechanical and refrigeration plant can be

         derived for surrounding residences as presented in Table 6.
