Dear Mr. Hodson:

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

Your request dated February 11, 2025, to relocate aggregate equipment to the temporary project
for the Kilgore Companies’ Stockton aggregate facility, located at 555 North Highway 36,

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

150 TPH screen plant
Metso Nordberg cone crusher
KPI cone crusher
KPI/JCI screen
Caterpillar 725 kW generator
Goodfellow bin feeder
Miscellaneous conveyors, feeders, and stackers

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
requirements for additional information.

This approval for relocation in no way releases the owner or operator from any liability for
compliance with all other applicable federal, state, and local regulations including the UAC.

process please contact Susan Weisenberg at [phone].

Sincerely,

Jay P. Morris

Subject: request for confirmaon of AO used for rental equipment

Hello, I have been asked by my management to confirm that the equipment referenced as "Rental" on your TRP
electronic submission for the Stockton facility is equipment rented from Goodfellow. Let me know if I should reference a
different portable AO on the relocation letter. Thanks
