All volume sources (refuelling, spillages and whoosh emissions) have been modelled based on the
analysis of wake effects presented in the LORAX report (Toxics Committee of the California Air
Pollution Control Officers Association 1997). Point sources (breathing) have been modelled in
accordance with the NPI data.

3.4.3      Fuel Throughput
Brisbane City Council recommends two methods of calculating the fuel dispensing throughput for a
service station:

⚫ Method 1 – If site data is available for total daily or weekly fuel sales:
          ⚫ Estimate daily petrol dispensing rate (preferably the peak rate not average)
          ⚫ Use the daily profile presented in Table 3.4 to apportion the amount of fuel dispensed
               per hour
