5 NOISE SOURCES/IMPACTS

The following sections outline current major noise sources that were identified upon the site visit to have
potential impact on site.

5.1 LOADING DOCKS
5.1.1. Trolley Collection

During time on site, the following was observed and considered in the assessment in relation to trolley
activity:

e As advised by the client, trolley collection occurs:
o Woolworths
" Monday-Saturday from 8am to 9pm
«= Sunday from 9am to 6pm
o BigW
= Monday-Saturday from 9am to 5pm
«= Sunday from 10am to 3pm
e« Measured trolley activity noise level of 69 dB(A) Leq

5.1.2 Delivery Trucks
The following observations were made regarding delivery trucks:

« Small to medium sized delivery trucks were present within the loading docks;

« No more than one truck in each hour is present at the loading docks;

e As advised by the client, the loading dock operational hours are:
o Monday to Saturday — 5am to 9pm
o Sunday — 8am to 6pm

e = Truck (incl. refrigeration truck) idling was only considered to occur in the loading dock during
nominal 15minute loading period, and not along the boundaries or at the entrance to the
loading docks;

« Where trucks enter the site to wait for loading as well as during loading (unless short-time drop-
off/pick-up), engines must be turned off;

e In the case of refrigeration trucks, these should just come in and leave site after loading as no
idling shall be allowed at other times;

e Such restrictions should be included if not yet followed (e.g. signs installed at the entry and
along the boundaries and within the shopping centre loading docks); and

e The modelling assumptions in Section 6.2 show specific activities and types of vehicles in each
individual loading dock

5.2 MECHANICAL PLANT

Mechanical plant that was observed is indicated in Figure 2 with the noise sources based on the attended
measurement results in Table 4. As advised by the client, the operational hours for the mechanical plant are
as follows:

« Monday to Saturday — 7am to 9pm
« Sunday — 8am to 6pm

Mechanical plant operational restrictions considered in the modelling are listed in Section 6.2.
