Dear Mr. Hodson:

Re: Kilgore Companies dba Legrand Johnson –Temporary Relocation/Operation, Notice of
Intent – Box Elder County

Your Notice of Intent dated November 27, 2023, to relocate portable aggregate equipment to the
temporary project for Legrand Johnson’s Knudson Pit, located at 1200 East 700 South, Brigham
City, Utah was received by the Utah Division of Air Quality (DAQ) and has been reviewed.

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

JCI-KPI screen with 129 hp diesel engine
Terex/Finley screen with 113 hp diesel engine

The State of Utah has permitted portable aggregate equipment for operation for your company on
the Approval Order (AO) DAQE-AN129310019-18 dated April 12, 2018. The above 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 Approval Order (AO)
for this site DAQE-AN132730007-17 dated June 2, 2017. 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. As per Condition II.B.1.b of this
same AO, the referenced equipment can only operate between 6:00 am and 6:00 pm and shall
operate for a maximum of 10 hours per day.

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 operational
days per site cannot be extended beyond the stipulated 365 consecutive day period.

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.

If you have any questions regarding this relocation authorization or the temporary relocation
process please contact Susan Weisenberg at [phone].

Sincerely,

Jay P. Morris

Hello Susan,

For these screens they are self-driven by diesel engines. For the JDI-KPI GT205S it has a 129 hp diesel engine and for
the Terex/Finlay 684 it has a 113 hp diesel engine.

Thank you,

Hello, I have the TRP Letter prepared for the two screens to the Brigham City Pit. Can you let me know if the screens will
be powered by an additional generator or will the equipment just be added to the current generator set up? Thanks
