Dear Mr. Pond:
Re: Request for Evaluation of Compliance with Rule R307-401-9, UAC: Small Source Exemption
Project Fee Code: N162690001
On April 23, 2025, the Division of Air Quality (DAQ) received your request for a small source exemption
for the reWater, LLC Tap Facility. The source is located approximately six miles southeast of Duchesne
at UTM (Universal Transverse Mercator) coordinates 556,548 meters Easting and 4,438,251 meters
Northing (Datum NAD 83, Zone 12) in Duchesne County. Operations on-site include the use of one (1)
118 horsepower (Site Rating of 96 horsepower) natural gas-fired generator set and one (1) condensate
storage tank. Per the registration request, the maximum annual oil production is 1,440 barrels of oil per
year. 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, reWater, LLC is not required to obtain an approval
order under R307-401 for the Tap Facility. 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.

Hello Tyson,
The Utah Division of Air Quality received your notice of tap facility on April 23rd, 2025. I have been assigned as the project
engineer to process this notification.
Based on the information submitted, I will be processing this project as a Small Source Exemption. Will you send me an
excel file that shows how you calculated the PTEs of the site? Please include any references, citations, or assumptions
you used to determine your emissions.
I look forward to working with you.
Cheers,
Katie Andersen

Thank you for these documents.
Some additional questions for you:
Is 4092 W 3000 S Roosevelt UT 84066 the correct mailing address?
What is the relationship between WEM Operating, LLC and reWater, LLC?
Cheers,
Katie Andersen

Hi Ka e,
I can help answer the rela onship ques on. ReWater and WEM Opera ng are both owned by Wasatch Energy
Management. The two LLC's operate as separate en es, however, the employees opera ng both companies are
WEM Opera ng employees.
Rewater owns all of our midstream assets, and WEM Opera ng is everything upstream.
Tyson as example, is an employee of WEM Opera ng, but he takes care of all emissions and compliance for both
companies.
Hopefully that makes sense.

Engines used in Moser generators meet applicable EPA standards for engine performance, equipment protection, and emissions control. Emissions are controlled via an
integrated air-fuel ratio controller, precision spark timing control, three-way catalytic converters, pre- and post-catalyst EGO sensors, and closed-loop emissions control
feedback. Catalytic converter health is further monitored with pre- and post-catalyst exhaust thermocouples and pressure transducers that measure backpressure. All
units are equipped with telematics that allow operating parameters to be monitored from anywhere at any time.

Except as expressly set forth in a written agreement with Moser Energy Systems executed by Moser Energy Systems and the party renting/leasing the generator(s) that is the subject of this
datasheet, Moser Energy Systems shall have no liability for any representations or warranties, and Moser Energy Systems hereby expressly disclaims all statutory, oral, expressed or implied
representations and warranties with respect to the generators. In the event that such parties enter into a written agreement with respect to the generators, Moser Energy System's maximum

All representations and warranties as to performance are dependent on a written agreement with Moser Energy Systems and with the submission to Moser, and Moser’s written approval of, a
current (<6 months old) gas analysis report and updated gas analysis reports every six months thereafter. Gas supplied to generator(s) must be free of liquids and hydrogen sulfide (H2S) and
any representations or warranties as to performance shall be dependent on satisfaction of this free liquids condition.
There are a number of factors that may affect emission measurements and therefore reliance on representations as to performance. Measured emissions levels are subject to
instrumentation and equipment variability. Production tolerances in engine, generator, and other components can account for variances in data of +/-5%. Actual field test results may vary
due to factors including, but not limited to, ambient conditions, fuel quality, produced water chemical content, installation, application, and instrumentation. Excessive intake or exhaust
restriction, excessive water in the fuel, or improper engine maintenance may result in elevated emissions levels.

Dear Mr. Bird,
This notice is to inform you that reWater, LLC is planning a small tap at the coordinates
of Latitude: 40.092651, Longitude: -110.336633, into Four Point Energy's gasline to the
Moon Ranch Compressor.
We will take gas off our 12" natural gas line, run it through a 10hp gas cooler and meter,
and inject it into Four Point Energy's 6" meter. The site will have a pig receiver and an
uncontrolled 100BBL tank for liquids. The estimated throughput for the tap is 1440BBLs
of condensate per year. The site will flow daily with pigging typically done weekly. The
Tank will be unloaded as needed expected to be monthly. Additionally, the site will have
a 70hp generator set using natural gas to drive it.
The site manager will be BJ Hadlock, who can be reached at 435-790-5609. For
estimated emission rates, please refer to the PTE table sent with this letter.
Thank you for your attention to this matter.
Sincerely,
Tyson Pond
