Federal Register / Vol. 86, No. 112 / Monday, June 14, 2021 / Notices increase from 85 psi to 100 psi within 25 seconds. Vehicles subject to the condition that has resulted in the noncompliance to paragraph S5.1.2.1
could increase air pressure from 85 psi to 100 psi in less than 6 seconds, well within the requirement of 24.14
seconds. Further, vehicles subject to this condition have a cut in pressure set at, or greater than, the minimum requirement of 100 psi.
The impact of having 2.7% to 2.8%
less air reservoir capacity than required, the difference in the cut in pressure requirement of only 1 second, would appear to have an adverse consequence of a slight increase in air compressor cycling. However, this would be dependent on application of the service brakes.
3. Emergency Vehicle Duty Cycle: The vocational duty cycle of a fire apparatus requires the emergency vehicle to respond to emergency situations that are predominantly short distances away, notwithstanding trips to a dealer or service provider. The number of times will vary between fire departments;
however, the duty cycle for a fire apparatus is intermittent when compared to an over-the-road vehicle.
While the braking applications in these short distances may be frequent, the air compressor would be able to maintain adequate air pressure in the air reservoir system. With the minimal lowered capacity, with the slightly less than a 1
second difference in filling the air reservoir system, the slightly lower than required capacity would likely not be noticeable to the driver.
4. Vocational Requirements: The National Fire Protection Association NFPA promulgates a vocational standard that defines requirements specific to the vocational aspect of the emergency vehicle. Within NFPA 1901
Standard for Automotive Fire Apparatus NFPA 1901, emergency vehicles subject to the requirements of the standard are required to be equipped with a quick build up section in the air reservoir system so that if the vehicle has a completely discharged air system, the apparatus would be able to be moved within 60 seconds. For those emergency vehicles that cannot be equipped with the quick build up section, they are required to be equipped with an on-board automatic electric compressor or shoreline hook up.
Additionally, NFPA 1901 requires all vehicles that have a gross vehicle weight rating GVWR greater than 36,000
pounds be equipped with an auxiliary braking system. This may be, depending on the option of the purchaser, a transmission retarder, an inline retarder,

or exhaust restriction device. All but 16
vehicles subject to this noncompliance have a GVWR of more than 36,000
pounds.
5. Air System Warning: The completed emergency vehicles subject to this condition are equipped with two air gauges that monitor the air system pressure in both System 1 and System 2. In addition to the air gauges, there are both a warning light and audible alarm to alert the driver of a low air condition.
6. Conclusion: The actual air reservoir capacity in the affected emergency response chassis cabs and emergency vehicles may be between 2.7% and 2.8% less than the calculated required amount. However, due to the duty cycle of an emergency vehicle, the vocational requirements, and the air compressor cycling that is well within the required time using the equation from FMVSS
No. 121, Spartan believes the noncompliance is inconsequential to motor vehicle safety. The less-thanrequired capacity does not appear to impact vehicle braking performance e.g., stopping distance, brake application, and release timing. The completed vehicles are equipped with dual air gauges and a visual and audible warning system to alert the driver to a loss of air in the air brake system.
Spartan concludes that the subject noncompliance is inconsequential as it relates to motor vehicle safety and that its petition to be exempted from providing notification of the noncompliance, as required by 49
U.S.C. 30118, and a remedy for the noncompliance, as required by 49
U.S.C. 30120, should be granted.
NHTSA notes that the statutory provisions 49 U.S.C. 30118d and 30120h that permit manufacturers to file petitions for a determination of inconsequentiality allow NHTSA to exempt manufacturers only from the duties found in sections 30118 and 30120, respectively, to notify owners, purchasers, and dealers of a defect or noncompliance and to remedy the defect or noncompliance. Therefore, any decision on this petition only applies to the subject vehicles that Spartan no longer controlled at the time it determined that the noncompliance existed. However, any decision on this petition does not relieve vehicle distributors and dealers of the prohibitions on the sale, offer for sale, or introduction or delivery for introduction into interstate commerce of the noncompliant vehicles under their control after Spartan notified them that the subject noncompliance existed.
