Dear Mr. Hodson:

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

Your Notice of Intent dated February 20, 2025, to relocate portable aggregate equipment to the
temporary project for Asphalt Materials, Inc.’s Sand Quarry, located at 14700 South 1075 West,
Bluffdale, UT, 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:

Metso HP3 cone crusher
Diester 8 x 20 screen
Caterpillar 455 kW generator

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
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

Good morning Susan,
I just submied a new TRP applicaon for our Bluffdale Pit. This is the same site as referenced in DAQC-590-24. I'm
sure you may need to ask because this TRP has not expired yet, but I just wanted to let you know that the equipment
from C-590-24 is no longer on site.
Thank you,
