          a.   before 7a.m, if it makes a noise of more than 3dBA above the background level; or
          b.   from 7a.m. to 10p.m, if it makes a noise of more than 5dBA above the background level; or
          c.   after 10p.m, if it makes a noise of more than 3dBA above the background level.

5.3.2          440V Refrigeration equipment
    3. This section applies to a person who is—
          a.   an occupier of premises at or for which there is plant or equipment for refrigeration
               (refrigeration equipment); or
          b.   an owner of refrigeration equipment that is on or in a vehicle, other than a vehicle used or to
               be used on a railway.
    4. The person must not use, or permit the use of, the refrigeration equipment on any day—
          a.   before 7a.m, if it makes a noise of more than 3dBA above the background level; or
          b.   from 7a.m. to 10p.m, if it makes a noise of more than 5dBA above the background level; or
          c.   after 10p.m, if it makes a noise of more than 3dBA above the background level.
    5. In this section—
        vehicle includes a trailer.

5.4            Environmental Protection (Noise) Policy
5.4.1          Overview
In respect of the acoustic environment, the object of the Act is achieved by the Environmental Protection
(Noise) Policy 2019 (EPP (Noise)). This policy identifies environmental values to be enhanced or protected,
states acoustic quality objectives, and provides a framework for making decisions about the acoustic
environment.

5.4.2          Background Creep
The EPP(Noise) identifies that background creep is to be prevented or minimised. Background creep is defined
as a gradual increase in the total amount of background noise in the area of place as measured under the
document called the ‘Noise measurement manual’.
Unlike the former 2008 EPP(Noise), there are no specific criteria proposed for the control of background creep.
It is therefore proposed to refer to noise criteria that have been used over a number of decades in Queensland
and are still used in the EP Act as offence criteria for mechanical plant, i.e.
◼      From 7am to 10pm, noise (inclusive of background noise) is to be no more than 5 dBA above the
       background level.
◼      Before 7am or after 10pm, noise (inclusive of background noise) is to be no more than 3 dBA above the
       background level.


5.5            Summary of Criteria
The proposed noise criteria are the background creep criteria, as follows:
◼      from 7am to 10pm, noise (LAeq,adj,T inclusive of background noise) is to be no more than 5 dBA above the
       background level (LA90,T).
◼      before 7am or after 10pm, noise (LAeq,adj,T inclusive of background noise) is to be no more than 3 dBA
       above the background level (LA90,T).
