Notice of Intent – Cache County

Your Notice of Intent dated June 14, 2024, to relocate portable generators to the temporary project

The State of Utah has permitted the portable generators for Kilgore Contracting, LLC on the

Hyrum Pit Generator TRP Request

Susan,

I just wanted to add some clarification to our request to use generators at our Hyrum pit, as we just submitted a TRP
application online. Unfortunately, we don’t have access to line power through the city that we need in order to run some of
our aggregate processing equipment at that site. We are not sure when we might have access to the amount of electricity
we would need to run all our equipment, so for now we are requesting a TRP in order to add two generators to the site.
Adding these generators is a temporary solution and we will be in communication with both the city along with the
consulting team we work with to modify and evaluate air quality permits so we can find a permanent solution to this
situation.

As a reminder this is in reference to TRP # C-189-24 for the following equipment to be used at our Hyrum site in Cache
County:

Equipment Type: Generator – Used to power Cedar Rapids 6x20 Screen Plant (one of II.A.6)
Make/Model: Cat C27
Serial #: 00C27PT4Z00341
Manufactured Date: 2014
Design Capacity: 725 kW
Equipment Type: Generator – Used to power Cedar Rapids Impactor Crusher (II.A.5)
Make/Model: Cat C27
Serial #: 00C27TT4Z00340
Manufactured Date: 2014
Design Capacity: 725 kW

Please let me know if you need any other information.

Thank you,

Tyler Hodson

Hi Susan,
I think this looks good and can be processed as a TRP through eSign.
Thanks,

Susan,
As long as it is temporary, I don't think there would be an issue, but I will defer to you and Chad.

Hello - Tyler Hodson, of Kilgore has requested a temporary relocation of two 725 kW generators to their Hyrum
facility (10055) due to a delay in obtaining sufficient electrical power outlets. The Hyrum pit was not permitted for
generators. Because of this, I asked Kilgore to submit a written request for why the TRP was necessary and how
the generators would be used. See the attached email. I have written up a draft potential relocation letter, in the event
that Kilgore's request is feasible.
Let me know if you have any questions - Thanks
