Cell: 725-309-3723

MAILING ADDRESS: Corporate Office:
P.O. Box 985004, Fort Worth, TX 76185-5004

OPERATING STATUS: The facility is considered to be indefinitely idled. Only periodic
maintenance checks are conducted on the mobile engines.

PROCESS DESCRIPTION:

When the plant was in operation:

This is a lime production plant. The rock face is bore hole blasted with Nitride explosives. The loosened
rock is then loaded into large haul trucks by a front-end loader. The section to be loaded is watered by a
water truck side sprayer prior to loading. This truck also does the road and work areas. The haul truck
takes this material down to the primary feeder. The feeder drops the material to a primary jaw crusher
then to a belt/stacker and to a large pile. This pile feeds to an under-pile belt and which feeds to the top of
a Tyler 2 deck screen. The screen separates the material to oversize, chaff, and usable product. The chaff
drops to a feed belt and then to a large silo. This material is gravity dumped into the haul trucks and
dropped on the road and working areas for road base and dust control. The oversize is dropped to a belt
and then to a cone crusher and then returned by a single belt to the feed line of the screen.
2
The product material is dropped to a stacker belt and then to a storage pile. There are water sprays at the
feeder, the jaw crusher, the screen, and the cone crusher. There are also several sprays along the
conveyors and at the stacker drops. The product from the pile drops to an under-pile belt and then to an
Allis Chambers screen which separates usable product and fines. The fines are returned to the main line at
the primary pile and the usable material is dropped to a conveyor which feeds to an elevator. This elevator
drops to the top of a 500-ton storage silo. The material gravity drops to a preheater (from the kiln heat)
and then by enclosed duct to the rotary kiln. The material goes through the kiln and drops to a quench
duct and then to an elevator, or to a hydrator and then to the elevator. The elevator takes the material to
one of ten storage bins ranging in size from 50 to 500 tons. The material goes through multiple ducts or
conveyors depending on size, quality, or intended sales. There is a small Tyler screen at the top of the
silos to separate product lines, although this screen can be bypassed if not needed. One of the silos is
gravity fed to a belt and then to a bag filler to make 40lb bags. This is an automatic operation (except for
stacking) and is done in an enclosed building. The material stacker and screen have water sprays. The kiln
exhaust is controlled by an electro scrubber. The silo loading and transfer operations are controlled by
several baghouses according to the silo being loaded or transferred to. The site has a drive under truck
loadout which has three expandable/sealing ducts for loading and is controlled by a baghouse. This can
also be used for train loadout with the same ducts. The kiln can be fired on natural gas, fuel oil, or tires.
The tire feeder is an automated system which places one tire at a time on a feed belt to the kiln burner.
This is used in conjunction with oil or fuel oil burning.

Current Operations:

This site is shut down. The only current operations are weekly (Thursday) loading of fines to trucks for
off-site use. This occurs no more than once per week and the purchasing company brings in a loader and
haul trucks. This has been ceased since November 2020 and startup date is unknown. The site has some
maintenance operations to keep equipment in operational order and does start/run plant, with no feed,
once per month. Additionally, the company gets two types of crushed product by rail from Las Vegas
plant, loads these products to separate storage bins then blends them and reloads to rail cars to ship to Las
Vegas. Two silos and two baghouses are used during this process which occurs several times per month
and is near completion with four rail cars scheduled for May and no planned operations past that.

Las Vegas Paving Corporation was issued a temporary crushing operation AO-DAQE-AN160410001-22.
The company no longer operates on the facility’s property.

I.N Emergency Provision.

I.N.1 An "emergency" is any situation arising from sudden and reasonably unforeseeable
events beyond the control of the source, including acts of God, which situation
requires immediate corrective action to restore normal operation, and that causes the
source to exceed a technology-based emission limitation under this permit, due to
unavoidable increases in emissions attributable to the emergency. An emergency shall
not include noncompliance to the extent caused by improperly designed equipment,
lack of preventive maintenance, careless or improper operation, or operator error.
(R307-415-6g(1))

I.N.2 An emergency constitutes an affirmative defense to an action brought for
noncompliance with such technology-based emission limitations if the affirmative
defense is demonstrated through properly signed, contemporaneous operating logs, or
other relevant evidence that:

emergency. (R307-415-6g(3)(a))

I.N.2.b The permitted plant was at the time being properly operated.
(R307-415-6g(3)(b))

I.N.2.c During the period of the emergency the permittee took all reasonable steps to
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))

8
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))

I.N.4 This emergency provision is in addition to any emergency or upset provision contained
in any other section of this permit. (R307-415-6g(5))

area shall be chosen either by the permittee or by the Director or his/her representative. An
opacity reading shall be made at each point when a vehicle passes the selected points.
Opacity readings shall be made one-half the vehicle length or greater behind the vehicle and

Good morning Duane,

As a follow-up to his inspection at Grantsville, the air inspector, Joe Rockwell, called me and asked for the date that we
paid the 2022 emissions fees. I am not finding the receipt in my files. Here is the information that Joe gave me:
1. The Utah DAQ invoice number is 240330
2. The invoice date is July 17, 2023
3. The due date for payment was October 21, 2023
4. The amount due was $1063.29

If you have the date of payment that will be enough. Obviously, a receipt or any other documentation of payment will also
be enough.

Thanks!

John
