Dear Mr. Hodson:

Re: Asphalt Materials Inc. – Temporary Relocation/Operation, Notice of Intent – Salt Lake
County

Your Notice of Intent dated June 14, 2024, to relocate portable aggregate equipment to the

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

McCloskey 154 HSI crusher screen combo with 510 hp engine
McCloskey track mounted conveyor with 100 hp engine

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 relocation
address is a permitted aggregate facility with established emission and production limits. All
equipment operating at this site must be in accordance with the current AO for this site
DAQE-AN119810009-15 dated December 7, 2015. The total production of aggregate from all
temporary projects when combined with the permanent equipment’s production cannot exceed the
12-month rolling limits as per the applicable limits of Conditions II.B.1.c.A and II.B.1.c.B. of this
AO. The operation of the diesel engines shall comply with the generator requirements of II.B.7.a
through II.B.7.c. Approval is granted to relocate and operate this equipment at the new location
for a period not to exceed 180 operational days.

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

Susan,

Some time after Kilgore Companies acquired Asphalt Materials Inc the choice was made to shut down both
the recycle plant and the topsoil screening plant, while making the crushing and processing of aggregates
the primary operation. As such, the two pieces of equipment we are requesting to add on a TRP will be used
to process aggregates separately from the main crushing and screening operations.

Please let me know if you have any other questions.

Thank you,

Hello Tyler, due to the explicit generator operation hour limits for the recycle plant and the topsoil screening plant at the
Bluffdale sand quarry - can you let me know what process the relocated equipment will be involved in producing? Thanks

Hello Susan,

We just submitted a TRP application for the Bluffdale Pit for 2 pieces of equipment. Since there is not a space to list
how they are powered I just wanted to let you know that information so you don’t have to reach out about it.

McCloskey I54 HSI Crusher Screen Combo
Standalone unit powered by a 510 hp engine
McCloskey Conveyor 36” x 80’
Standalone unit powered by a 100 hp engine

Thank you,
