          compressors, pumps etc. on site must be located within the building or suitably
          provided with noise reduction measures and located to prevent a noise nuisance
          beyond the boundary of the site and to not exceed the levels specified in Table 1.
          Table 1

          NOISE LIMITS AT A SENSITIVE RECEPTOR

          PERIOD           Noise level at noise sensitive place measured as the adjusted
                           maximum sound pressure level (Lamax, adj,T)

          7am – 6pm        Background noise level (LAbg,T) plus 5 dB(A)

          6pm – 10pm       Background noise level plus 5 dB(A)

          10pm – 7am       Inaudible

          NOISE LEVELS AT COMMERCIAL PLACE

          PERIOD           Noise level at a commercial place measured as the adjusted
                           maximum sound pressure level (Lamax, adj,T)

          7am – 6pm        Background noise level (LAbg,T) plus 10 dB(A)

          6pm – 10pm       Background noise level plus10 dB(A)

          10pm – 7am       Background noise level plus 8 dB(A)

    96.   When requested by Council, a Noise Impact Assessment Report (NIAR) showing
          monitoring and recording of noise levels must be undertaken to investigate any
          complaint (other than a frivolous or vexatious complaint) caused by noise emissions
          from operations at the premises.
    97.   Such monitoring must be undertaken within a reasonable and practicable timeframe
          nominated by Council and be performed by a suitably qualified person in accordance

          achieve compliance with limits outlined in Table 1 of this Decision Notice.
          For the purpose of measuring and certifying relevant noise conditions and reporting
          (e.g. mechanical plant and equipment, a/c units, motors, refrigeration equipment,
          compressors, pumps, rooftop plant and equipment. etc) a suitably qualified person is
          either:
          a.   a Registered Professional Engineer of Queensland, or
          b.   an environmental consultant with a minimum of three (3) years current
               experience in the field of acoustics.
