Fact Sheet:Amendments to R307-328:Dripless Nozzles and Low
Permutation Dispensing Hoses
Overview:
The Utah Division of Air Quality (UDAQ)is considering amendments to existing administrative
rule R307-328 to further reduce volatile organic compound (VOC)emissions from gasoline
dispensing stations.The proposed amendments are part of the state's efforts to reduce
summertime pollution and comply with federal Clean Air Act1 requirements as part of the
Northern Wasatch Front ozone State Implementation Plan.This rule would apply to each gas
dispensing station operating in counties located in and around the nonattainment area (NAA)
including Salt Lake,Davis,Weber,Utah,and Tooele counties.
Exemptions:
The proposed amendments do not apply to gasoline dispensing equipment used on private
agricultural lands with the sole use for agricultural operations.
Equipment:
The proposed amendments would require the installation of low permeation hoses2 and dripless
dispensing nozzles3 at each gasoline dispensing pump located in the five applicable counties.
The average lifespan of this equipment has been reported to be at least three years.
The proposed low emission technology results in a control efficiency of 92.9%representing a
substantial reduction in ozone forming emissions.
Compliance Schedule:
Consistent with statutory compliance timelines as required by the Clean Air Act,the low
emission equipment associated with the proposed amendments would be required to be
installed by May 1,2026.4
Emission Reductions:
The UDAQ has identified 581 businesses operating approximately 6,863 gasoline dispensing
pumps in the applicable counties.As each gasoline dispensing pump typically houses two
dispensing nozzles and corresponding hoses,the UDAQ estimates that there are 13,726
gasoline dispensing nozzles and associated hoses operating in the same area.

●Low Permeable Hoses:Reduction of 35.96 tons per year (tpy)VOC emissions.
●Dripless Nozzles:Reduction of 179.0 tpy VOC emissions.
●Total:214.96 tpy,or 0.59 tons per day,of VOC emissions reductions is anticipated with
the addition of the proposed amendments.
Capital Costs:
The UDAQ has identified the following capital costs associated with the proposed amendments
as determined by the incremental costs difference of the proposed low emission equipment
relative to standard nozzles and hoses:
●Incremental costs of low permutation hoses:$183 per eight feet of hose.
○Total incremental cost of all hoses:$2,511,858.
●Incremental costs of dripless nozzles:$290 per certified nozzle.
○Total incremental cost of nozzles:$3,980,540.
●Total incremental capital cost:$6,492,398.
Lifetime Cost Savings (3 years):
The UDAQ has identified a lifetime cost savings over the anticipated three-year lifetime of the
dripless nozzles and low permeable hoses resulting from the reduction of lost gasoline products
for consumers.
●Low Permeable Hoses:$103,737 lifetime savings5 for consumers.
●Dripless Nozzles:$515,745 lifetime savings for consumers.
●Total lifetime savings to consumers:$619,482.
Secondary Benefits:
●Significant reduction in spilled and lost product from gas dispensing nozzles saving
consumers money post purchase of gasoline.
●Reduced loss of gasoline products through evaporative losses through low permutation
hoses saving consumers money.
●Cost savings to gas dispensing stations due to reported longer lifespan of dripless
nozzles.
