Dear Mr. Mendell:

Re: Request for Evaluation of Compliance with Rule R307-401-9, UAC: Small Source Exemption
Project Fee Code: N162100001

On April 16, 2024, the Division of Air Quality (DAQ) received your request for a small source exemption
for the United Parcel Service (UPS) Emergency Generator. The source is located at 3815 West 1580
North, Salt Lake City, Salt Lake County. DAQ has determined the small source exemption applies to the
source as long as the equipment and associated processes operate as specified in the registration request.

The small source exemption does not exempt a source from complying with other applicable federal,
state, and local regulations and the current Utah Administrative Code. Based on the emissions that you
submitted to DAQ with your registration request, UPS is not required to obtain an approval order under
R307-401 for the Emergency Generator. If you change your operation such that there is an increase in
emissions, we recommend that you notify us, as an approval order may be required.

As authorized by the Utah Legislature, the fee for issuing this small source exemption is a one-time filing
fee in addition to the actual time spent by the review engineer and all other staff on the project. Payment
should be sent to DAQ upon receipt of the invoice.

Engine
Cummins heavy duty diesel engines use advanced combustion technology for reliable and stable power, low emissions, and
fast response to sudden load changes.
Electronic governing provides precise speed regulation, especially useful for applications requiring constant (isochronous)
frequency regulation such as Uninterruptible Power Supply (UPS) systems, non-linear loads, or sensitive electronic loads.
Optional coolant heaters are recommended for all emergency standby installations or for any application requiring fast load
acceptance after start-up.
Note: Features included with the engine: battery charging alternator, fuel/water separator, shutdown low coolant and bypass
oil filtration.

Alternator
Single-bearing alternators couple directly to the engine flywheel with flexible discs for drivetrain reliability and durability. No
gear reducers or speed changers are used. Two-thirds pitch windings eliminate third-order harmonic content of the AC
voltage waveform and provide the standardization desired for paralleling of generator sets.
A Permanent Magnet Generator (PMG) excitation system limits voltage dip during transient load application, sustains 3-phase
short circuit current at approximately three times rated for up to 10 seconds, and is resistant to harmful effects of harmonics
generated by non-linear loads. The alternator delivers excellent performance in applications containing large motors or
sensitive electronics.
Various alternator sizes are available to meet individual application needs. Alternator sizes are differentiated by maximum
winding temperature rise at the generator set standby or prime rating when operated in a 40oC ambient environment.
Available temperature rises range from 80oC to 150oC. Not all temperature rise selections are available on all models. Lower
temperature rise is accomplished using larger alternators at lower current density. Lower temperature rise alternators have
high motor starting kVA, lower voltage dip upon load application, and they are generally recommended to limit voltage
distortion and heating due to harmonics induced by non-linear loads.
Alternator Application Notes
Alternator Space Heater - is recommended to inhibit condensation.

Response Summary:
To be eligible businesses shall not do any of the follow:

1) Emit more than 5 tons per year of each of the following pollutants: Sulfur Dioxide (SO2), Carbon Monoxide (CO),
Nitrogen Oxides (NOx), Particulate Matter (PM10), Ozone (O3), or Volatile Organic Compounds (VOCs).

A copy of this registration notice and worksheets are required on site to verify permit exemption status.

Please be aware a the Small Source Exemption ONLY exempts the site from the air permitting requirements of R307-
401-5 thru R307-401-8 of the Utah Administrative Code, all other air quality regulations still apply.

Q5. County the Site is located in:
Utah County

Q6. Briefly describe the process including the end products, raw materials, and process equipment used.
The UPS air operations has a newly installed backup generator located at their airport facility. The generator runs for
30 minutes each week (on Mondays) for diagnostic testing. The generator has been installed specifically for backup in
the event of total power failure to our building. There are no plans to use this generator as an exclusive power source.
We are submitting this small source exemption as we expect to only run the generator for roughly 28 hours annually.

Q7. List emission units
Exhaust Emission Data at Full Standby:
HC (Total unburned hydrocarbons) = 0.14
NOx (Oxides of Nitrogen as NO2) = 4.43
CO (Carbon Monoxide) = 0.39
PM (Particulate Matter) = 0.02
Smoke (Pierburg) = 0.21
All values (except smoke) are cited: g/BHP-hr
EPA emissions compliance statement will be attached.
