Dear Mr. Hodson:

Re: Kilgore Companies, LLC dba Asphalt Materials Inc. – Temporary Relocation/Operation,

been reviewed.

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

TC-20 HSI crusher with Cat C13B 456 HP generator
TS-516 screening plant with Cat Cr.4 130 HP 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 referenced
location is a permitted facility with established production limits. All equipment operating at this
site must be in accordance with the current Asphalt Materials Incorporated
AO DAQE-AN103430009-07 dated April 13, 2007. The production of recycled product from the
temporary equipment when combined with the permanent equipment’s production cannot exceed
the 12-month rolling limits as per Condition 13.C of this AO.

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.

Subpart OOO also mandates that all crushers constructed, modified, or reconstructed on or after

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

Hi Susan,

The equipment will only be used to recycle concrete, asphalt and soils, so there won’t be any aggregate
mining with the equipment. For the generators, each piece of equipment has it’s own diesel engine
attached:

1. TC-20 HSI Crusher:
a. Cat C13B 456 HP
2. TS-516 Screening Plant:
a. Cat C4.4 130 HP

Please let me know if you need any other information for this TRP.

Thank you,

Tyler Hodson

Hello Tyler, the DAQ is currently requiring generator information for every TRP. Can you let me know if this crusher and screen will
be powered by a diesel fired generator or if it will be powered electrically. Also - can you confirm that the equipment will be used to
recycle product (as opposed to actual aggregate mining)?

Thanks - It may be possible that we need to update our electronic TRP form to include check boxes for electrical power and
recycling projects.
