OPERATING STATUS: Operating. Line #3 was shut down on July 19, 2023, due to economic
conditions.

PROCESS DESCRIPTION:

Brick and Structural Clay Manufacturing Facility:

Material Processing: Clays are trucked to the facility from Utah Lake, Southern Utah, and Wyoming.
(FEL’s) mix different clay types from the storage piles and transfer the material either to the primary
crusher or to a covered storage pile area. Cracked or damaged bricks from the end of the manufacturing
process are also add to most blends in small quantities known as “grog.”

All raw materials pass through the primary crusher before being conveyed to the screening building.
Next, the material passes through one of four grinders located in the screening building. The fine ground
material is then screened to a suitable size for brick formation. Screened material is transferred to one of
3 operating brick lines by being conveyed to the reclaiming building. Line #1 has not been used since
1982, and will not be used until the scrubber is replaced. Line #2 is permanently shut down.
2
Lines #3 and #4 are fed from their respective reclaimers. Line #5 which was a specialty line, has been
permanently shut down. The material is then pushed by a reclaimer onto conveyors that lead to the
appropriate brick line.

Brick Line Processing: Additives such as Manganese, Barium Carbonate and Iron Chromate are blended
to the conveyed material to prevent leaching. The material drops into a pug mill that mixes the materials
and adds water to form thick clay. Next, the blended material is discharged through a vacuum chamber
that removes air. The material is then extruded through a die, where the clay is formed into the
appropriate shape and is cut to size, creating “green” bricks. Finally, the green bricks are placed onto kiln
cars that transport the bricks to the appropriate brick line holding room.

Brick Line #3 (Residential Line) Processing: The holding room, of lines #3, pre-dries the bricks prior
to entering the tunnel dryer which further dries the bricks. The holding room and tunnel dryer use waste
heat from the tunnel kiln’s cooling zone. Next, the bricks enter the firing zone (~2200°F) of the tunnel
kiln. The waste heat and combustion exhaust are vented outside the building. Finally, the bricks are
cooled in the cooling zone, to ambient temperature, before leaving the tunnel kiln.

Brick Line #4 (Architectural Line) Processing: This line is used primarily for commercial work and is
equipped with 2 extruders. A small extruder is used to make accessory bricks. The accessory bricks are
dried in the shapes dryer. This dryer utilizes natural gas for combustion, with exhaust vented outside t he
building. Bricks from the main extruder are loaded onto pallets to be individually dried in the pallet
dryer. The pallet dryer uses waste heat from the cooling zone of the tunnel kiln to dry the bricks prior to
entering the holding room. The waste heat used in the pallet dryer is vented outside the building.

After leaving either the shapes dryer or pallet dryer, the bricks enter the preheater. The preheater uses
waste heat from the cooling zone of the tunnel kiln to heat the bricks to ~500°F. The bricks then move on
to the firing zone (~2200°F) of the kiln. The waste heat and combustion exhaust are currently vented
outside the building. Finally, the bricks are cooled in the cooling zone, to ambient temperature, before
leaving the tunnel kiln.

Shipping Finished Product: Finished bricks are packaged into cubes or are palletized. The cubes or
pallets of brick are staged before being loaded onto trucks or rail cars for shipment. This company has a
maximum production capacity of 18-cars/day/tunnel kiln.

minimize levels of emissions that exceeded the emission standards, or other
requirements in this permit. (R307-415-6g(3)(c))

I.N.2.d The permittee submitted notice of the emergency to the Director within two
working days of the time when emission limitations were exceeded due to the
emergency. This notice must contain a description of the emergency, any steps
taken to mitigate emissions, and corrective actions taken. This notice fulfills the
requirement of Provision I.S.2.c below. (R307-415-6g(3)(d))

I.N.3 In any enforcement proceeding, the permittee seeking to establish the occurrence of an
emergency has the burden of proof. (R307-415-6g(4))

Bryce C. Bird, Director
Utah Division of Air Quality
Department of Environmental Quality
195 North 1950 West
Salt Lake City, UT 84114-4820

Dear Mr. Bird:

This letter is intended to serve as official notice to the Utah Department of Environmental Quality, Division
of Air Quality, that as of Wednesday, July 19, 2023, Interstate Brick has temporarily shut down the Line 3
Manufacturing Line and the Line 3 Kiln. The associated air pollution control devices, the Line 3 Baghouse
and the Line 3 Scrubber have been shut down as well. Recordkeeping as required by our Title V Permit
#3500200001 will continue. It is anticipated at this point that the shutdown will last from six to twelve months.

The shutdown of this residential brick line was a very recent business decision made at corporate level because
of increased costs for natural gas, equipment/parts, raw materials and labor. We are hopeful that the overall
economy will improve in the coming months and some these high costs can be mitigated so we can reenter
this part of the brick market and supply our local and national distributors.

Please call me direct if you need additional information or have any questions.

Sincerely,

Travis DuVall
Plant Manager

Hello Joe -
I wanted to update you on our progress to get these revised Interstate Brick reports to you.
Some of the tables for our Excess Emissions reporng were created by a firm outside Interstate Brick and
we've had to reach out to them to get them updated.
Hopefully they'll complete the updates by week's end and I can send you the revised reports early next
week.
Apologies for the delay. Your connued paence is appreciated.
Sincerely,
Joseph Eck | EHS Manager -Tech & CADD Support
