REVIEWER COMMENTS

1. Comment regarding 10-Year Review:
The source is not modifying and/or installing any new equipment.

The rule references have been renumbered, the equipment list is separated into another area in the
2023 AO, and the text of each rule and condition have been modified to reflect the current language
and formatting. [Last updated December 6, 2023]

2. Comment regarding NSPS & MACT Applicability:
NSPS
NSPS Subpart OOO applies to each crusher, screening operation, and belt conveyor in fixed or
portable nonmetallic mineral processing plants manufactured after August 31 1983. The portable
equipment in this AO is used to process nonmetallic minerals according to 40 CFR 60.671;
therefore, NSPS Subpart OOO applies to this AO for portable equipment.

NSPS Subpart IIII applies to owners and operators of stationary CI ICE that commence construction
after July 11, 2005, where the stationary CI ICE are manufactured after April 1, 2006. The engines at
this portable source were manufactured after April 1, 2006; therefore, NSPS Subpart IIII applies to
this AO for portable equipment.

MACT
40 CFR 63 MACT Subpart ZZZZ applies to owners and operators of stationary RICE at a major or
area source of HAP emissions. This source has stationary RICE at an area source of HAP emissions;
therefore, MACT Subpart ZZZZ applies to the engines at this facility. [Last updated December 6,
2023]

3. Comment regarding Title V Applicability:
Title V of the 1990 Clean Air Act (Title V) applies to the following:

1. Any major source
2. Any source subject to a standard, limitation, or other requirement under Section 111 of the Act,
Standards of Performance for New Stationary Sources;
3. Any source subject to a standard or other requirement under Section 112 of the Act, Hazardous
Air Pollutants.
4. Any Title IV affected source.

The portable equipment in this AO is not part of a major source or a Title IV source, and is not
subject to 40 CFR 61 requirements, but the facility is subject to 40 CFR 60 NSPS Subpart OOO
requirements. Therefore, Title V applies to the facility as an area source. [Last updated December 6,
2023]

Good afternoon Todd,
My name is Dungan Adams and I am with the Utah Division of Air Quality (UDAQ). As part of the UDAQ's 10-year review
process I have been assigned to review the Approval Order (AO) DAQE-AN145490001-12, dated September 26, 2012,
for CMC Rock, LLC Portable Aggregate Processing Equipment. I have attached the AO for your reference.
The 10-year review process is conducted to update older approval orders with new language and formatting, but also to
ensure any necessary changes to the permit are made. It is free of charge.
I have received your contact from the DAQ's most recent compliance evaluation and wanted to ask if you are able to
answer further questions? If not, would you please direct me to the appropriate individual.
Thanks and let me know if you have any questions.

Todd,
Thanks for getting back to me. Please answer the following questions via email so the Division of Air Quality can keep a
record of the responses.
1. Can you please advise if the portable equipment is still operational and requires a permit? If not, it may be in your
company's best interest to request a revocation letter.
2. Please review the AO. Do any changes need to be made (such as a new mailing address, contacts, etc.)?
3. May I use you as the primary contact for this source? If not, could you please direct me to the appropriate individual.
Currently Rick Miller is listed as the primary contact.
Let me know if you have any questions.

Dungan,
Yes this equipment is still operational, I do however need to do some replacement in kind on the equipment. Can you
please send me what I need to do in order to accomplish this?
We also are looking at adding equipment would it be better to apply for a new portable permit or add it to this one?
As for the primary contact can you put me.

Hi Sam,
Sorry for the delay. Here are the requirements for Replacement-in-Kind Equipment:
(a) the potential to emit of the process equipment is the same or lower
(b) the number of emission points or emitting units is the same or lower
(c) no additional types of air pollutants are emitted as a result of the replacement
(d) the pollution control is functionally equivalent to the replaced equipment
(e) the replaced equipment is permanently removed
(f) the replacement equipment does not trigger any new federal or state standards
If the replacement equipment meets these requirements then you need to submit written notification to the DAQ
specifying the replacement equipment and demonstrating that the above conditions are met. Let me know if you have any
questions about that and I can send you the more detailed code.
As for whether or not to add to the existing permit or request a new one it's really up to you. If you want the flexibility to be
able to move the new equipment different places from the current equipment, I'd apply for a new portable. If it's all going
to stay together, then a modification would make more sense. The cost should be the same.
Thanks,

Hi Sam,
Sorry for the delay. Thank you for the notification of the replacement-in-kind. All of the equipment qualifies and no
changes need to be made to the permit in order to make the changes. As for the portable plant, I've attached two forms
that you will need to fill out for the application. Let me know if you have any questions.
I am still working on the 10-year review for Approval Order DAQE-AN145490001-12 and will let you know any questions
come up.
Thanks,
Dungan
