2. These Regulations apply to the flow rate from any nozzle that is used to dispense gasoline, or a gasoline blend, that contains benzene, but do not apply to the flow rate from any nozzle that is used exclusively to dispense gasoline or a gasoline blend into heavy-duty vehicles.

3. No retailer or wholesale purchaser-consumer shall use or offer for use a nozzle to dispense gasoline or a gasoline blend into an on-road vehicle if the flow rate from the nozzle exceeds 38 L/min.

• 4. (1) A person shall determine the flow rate referred to in section 3 by measuring the amount of time it takes to dispense 10.0 L of gasoline or a gasoline blend from the nozzle with the nozzle operated at the maximum flow rate.

• (2) In making the determination referred to in subsection (1), the person shall

  • (a) use a digital stopwatch that reads to at least 0.01 seconds to measure the dispensing time;

  • (b) use the dispenser’s volume meter to measure the dispensed volume of gasoline or gasoline blend; and

  • (c) start the stopwatch when the dispenser’s volume meter indicates that 2.0 L of gasoline or gasoline blend have been dispensed.

• (3) The person shall use the following formula to calculate the dispensing flow rate of gasoline or a gasoline blend from the nozzle, in litres per minute:

  Flow Rate = 60 × [V_f - V_i]/[T_f - T_i]

  where

  T_i 

  is the reading of the stopwatch, in seconds, when the person starts the stopwatch;

  T_f 

  is the reading of the stopwatch, in seconds, when the person stops the stopwatch;

  V_i 

  is the reading of the dispenser’s volume meter, in litres, when the person starts the stopwatch; and

  V_f 

  is the reading of the dispenser’s volume meter, in litres, when the person stops the stopwatch.

5. These Regulations come into force 12 months after the day on which they are registered.
