SOURCE NOISE LEVELS

From previous noise level measurements conducted by the consultant of general service station
forecourt noise and tanker fuel delivery (applicable for both petrol and diesel fuel delivery) to a service
station, the source noise levels, measured as one hour samples were:

   forecourt activities:             50 dB(A) LAeq,adj,1hr, 60 dB(A) LA1,adj,1hr and 53 dB(A) LA10,adj,1hr @ 15 m
                                      from the centre of the forecourt area;
   fuel delivery:                    72 dB(A) LAeq,adj,1hr, 80 dB(A) LA1,adj,1hr and 76 dB(A) LA10,adj,1hr @ 3 m.

With respect to the above noise sources, these included:

        forecourt activities, including the associated service station shop – vehicles (cars, four wheel
         drives and motor cycles) arriving at bowsers and at the service station shop, vehicle doors
         opening and closing, bowser handles removed and replaced, engines stopping and starting,
         people laughing and talking, tyre pressure gauge alarm and service station shop building door
         closing;

        fuel delivery – truck arriving, parking (including truck braking), placement of safety cones, truck
         engine idling, truck door open and closed, removing metal caps from truck outlet pipes,
         connecting hose one and hose two, fuel unloading, disconnecting the two hoses and replacing
         the metal caps, storing the hoses on the truck, throwing the safety cones back onto the truck,
         truck door closing and truck departing;

From a recently completed noise assessment at a service station refurbishment with a new shop and
fast food premises the plant and equipment noise levels associated with the shop and fast food
premises were:

        refrigeration:
              o plant 1 (2 of):                 70.9 dB(A) LWA;
              o plant 2 (1 of):                 64 dB(A) @ 3 metres; and
              o plant 3 (1 of):                 59 dB(A) @ 3 metres;

        airconditioning, 74 dB(A) LWA (2 of).

The combined noise level of the airconditioning and refrigeration plant would be, at a standardised
separation distance of 10 metres:

        plant 1:                     70.9 – 28 (distance) = 42.9 dB(A);
        plant 2:                     64 – 10 (distance) = 54 dB(A);
        plant 3:                     59 – 10 (distance) = 49 dB(A);
        airconditioning:             74 – 28 (distance) = 46 dB(A);

        combined:                    42.9 + 42.9 + 54 + 49 + 46 + 46 = 56.5 dB(A), which would be
                                      equivalent to:
                                          o 53.5 dB(A) LAeq,adj,1hr, 56.5 dB(A) LA1,adj,1hr and 54.5 dB(A)
                                              LA10,adj,1hr at a distance of 10 metres

From noise assessments of fast food premises the following additional noise sources should also be
noted:

        delivery truck:              65 dB(A) LAeq,adj,T, 67 dB(A) LA10,adj,T, 70 dB(A) LA1,adj,T @ 6 m;
        waste collection:            70 dB(A) LAeq,adj,T, 72 dB(A) LA10,adj,T, 74 dB(A) LA1,adj,T @ 6 m.
