Dear Mr. Hodson:

Re: Kilgore Companies, LLC – Temporary Relocation/Operation, Notice of Intent – Tooele
County

Your Notice of Intent dated March 7, 2024, to relocate portable aggregate equipment to the

been reviewed.

The following equipment has been approved for operation for this temporary project:

KPI K-350 cone crusher
KPI/JCI screen
Bin feeder

The State of Utah has permitted portable equipment for Kilgore Contracting, LLC on the
Approval Order (AO) DAQE-AN129310019-18 dated April 12, 2018. The above referenced
location is a permitted aggregate facility with established equipment hours of operation and
production limits. All equipment operating at this site must be in accordance with the current
Stockton Facility AO DAQE-AN140310004-22 dated December 22, 2022. The production of
aggregate from all temporary projects when combined with the permanent equipment’s production
cannot exceed the 12-month rolling limits as per Condition II.B.1.a of this AO. The operation of
the equipment must be compliant with this facility’s hourly limits as established by Conditions
II.B.1.b, II.B.1.c, II.B.1.d, and II.B.1.e.

Approval is granted to relocate and operate this equipment at the new location for a period not to
exceed 180 operational days. As per Utah Administrative Code (UAC) R307-401-17, the
operation of equipment at this temporary site may be for up to 180 working days in any calendar
year not to exceed 365 consecutive days, starting from the initial relocation date.

The owner/operator shall maintain records of the actual operation hours, days, and production
rate, of the above referenced equipment at this relocation site and have the ability to submit the
information to the DAQ upon the request of representatives of the director. Please make certain
that the plant operator is aware of all the location specific requirements for this site and the
conditions of the aforementioned AO.

Federal New Source Performance Standards Subpart OOO requires that initial Method 9
observations be performed for all applicable portable crushers, screens and attached conveyors.
Subpart OOO also mandates that all crushers constructed, modified, or reconstructed on or after
April 22, 2008, which are not enclosed, must install spray bars on the equipment and keep
maintenance records to ensure proper spray bar operations.

Utah Division of Water Quality Storm Water Permits and regulations may apply to this temporary
project. Please refer to Utah DEQ Water Quality’s current Storm Water Construction

process please contact Susan Weisenberg at [phone].

Jay P. Morris

Hi Susan,

I can confirm that there will not be a generator brought on site and this equipment will be run on line power.

Thank you,

Subject: generator queson regarding TRP to Stockton

This message originated from outside your organization
Hello Tyler, I received the relocation submission for Stockton this morning and I noticed that there's not a reference to a generator.
Can you let me know if this equipment will be powered by an electrical line or if there will be a diesel fueled generator?

Thanks
Susan Weisenberg,
