all time periods. Realistically, night time activity will be less frequent than daytime and as a result is predicted
to yield lower noise levels.

6.2.4        Deliveries and Waste Collection
It is understood that the deliveries and waste collection activities will be completed from the existing country
club. Deliveries will be dropped off at the existing country club and then transported up the hill to the proposed
development. Waste will be collected and transported down the hill to the existing country club for overall
collection. GH Australia has noted that the transporting of goods will be done via electric motorised golf carts
and the expected noise levels would be relatively low.
With the deliveries and waste collection activities occurring at the existing clubhouse, it is not expected the
increase in these activities would have a significant noise impact. Deliveries and waste collection activities are
still suggested to be limited to daytime hours 7am to 6pm. The activities are described as follows:
◼     A vacuum pump truck will extract grease from the underground grease trap at approximately number
     23 shown in Figure 3.1. We are informed pumping out the grease trap will take 15 to 30 minutes and is
     likely to occur once every two months. The assessment for the vacuum pump truck can be found in
     Section 6.2.4.1.
◼    Linen Deliveries may also occur on 3 occasions each week via the service road at approximately number
     “23” shown in Figure 3.1. A sound power level of 98 dBA for the delivery vehicle has been adopted with
     a period sound power level LW,eq of 61 dBA, which is based on 2 movements (to and from) and a speed
     of 10-40 km/hr. It was found that the linen truck delivery had no adverse effects on the predicted noise
     levels at R1, R2 or R3.

6.2.4.1      Waste Collection – Grease Pump
It is understood that a grease trap located at the hotel loading dock area requires emptying every 1 to 2
months to remove any residue. This involves bringing in a pump truck that is equipped with a vacuum pump
to clear the grease in the trap. The sound power levels produced by the vacuum pump were provided by
Haztek. The sound power level and calculated sound pressure levels at 1m can be found in Table 6.5.

 Vacuum Pump H400W (5m away)            84                                     112.3
 Vacuum Pump H400W (10m away)           80                                     112.8
 Vacuum Pump H400W (15m away)           77                                     112.7

When the sound power levels in Table 6.5 are averaged, the resultant sound pressure level comes to be
112.6 dBA. The vacuum pump was added to the model and its impact on nearby receivers has been
documented in Table 6.6.
Table 6.6: Vacuum Pump Noise Level Predictions

 Receiver                     Predicted Noise Levels with Vacuum Pump
                                                                      Day
             R1                                                        65
             R2                                                        37
             R3                                                        33

As seen in Table 6.6, the presence of the vacuum pump results in compliant noise levels at receivers R2 and
R3. On the other hand, receiver R1 experiences noise levels up to 65 dBA, which is 26 dBA above the 39 dBA
