portable nonmetallic mineral processing plant manufactured after August 31, 1983. If the source
operates any of this equipment using this portable AO, Subpart OOO will apply to the source.

40 CFR 60 Subpart IIII applies to "owners and operators of stationary CI ICE that commence
construction after July 11, 2005". If the source operates this equipment using this portable AO,
Subpart IIII will apply to the source.

40 CFR 63 Subpart ZZZZ applies to owners and operators of a RICE at any area source of HAP
emissions. If the source operates this equipment using this portable AO, Subpart ZZZZ will apply to
the source.

Good Afternoon Andy,
I believe Mark Oviatt forwarded you this information about a week ago so I apologize if any of this is repetitive.
As part of the Utah Division of Air Quality's 10-year review process I have been assigned to review the Approval Order
(AO) DAQE-1125-92, dated December 28, 1992, for a Kimball Equipment Portable Crushing Plant. I have attached the
AO for your reference.
Based on a call with Lyle Ellis, I was advised to update the contact address from PO Box 1103, Salt Lake City UT, 84110
to PO 1137, Salt lake City UT, 84110. Mark Oviatt is the primary contact for the original permit, please let me know if that
needs to be updated.
Please take a look at the attached permit and advise if any other changes need to be made.
Thanks,

Andy,
Thank you for your time this morning.
Based on our discussion this morning, Kimball Equipment currently has five portable crushers of various sizes that are all
listed on separate portable Approval Orders (AOs/permits) issued in the early 1990s. Kimball Equipment does not
operate any of these crushers and only rent them out to companies doing temporary crushing projects across the state.
From a compliance standpoint, it would make more sense to consolidate all of these AOs/permits into one generic
portable permit and remove all references to the stationary (24-hour crushing limit, haul road length, storage pile size,
etc.) permit conditions currently found in the existing December 28,1992, permit and March 12, 2024, Engineering
Review.
Thanks and please let me know if you have any questions.
Chad

Hi Andy,
I agree with Chad that it would be nice to remove the outdated stationary (24-hour crushing limit, haul road length, storage
pile size, etc.) permit conditions and consolidate Kimball's portable Approval Orders (AOs) into one permit. However, I've
spoken with my manager about this project and removing the stationary conditions without a public comment period would
be viewed as a permit relaxation. This means I cannot remove the stationary permit conditions and update to the generic
portable permit through the free 10-year review process.
If you want to remove the stationary conditions and consolidate everything into one generic portable permit, you will need
to go through a permit modification. Another option would be to apply for a new portable AO consolidating all of the
crushing plants and then revoke the old ones. Here is a breakdown of the fees if you are interested in that route.
If you are not interested, I think it may be best to stick with the existing December 28,1992 permit (DAQE-1125-92).
Updating the permit through the 10-year review process would carry over the outdated standard conditions as listed in the
Engineering Review I sent to you on March 12th, 2024. This seems a little redundant and might further complicate
inspections for the compliance section.
Let me know what you think and if you have any questions,
Thanks,
Dungan

Dungan,
We have decided to stay with the December 28,1992 permit (DAQE-1125-92) wording and proceed with the
free 10 year review.

Also,
I will be handing this of to our Salt Lake City location General Manager Mike Schultz. He will be your contact
for future concerns.

Hi Chad,
The source has decided not to pursue a permit modification to update all of their old portable permits.
How do you think we should proceed? I spoke with Alan this morning and he wanted me to get your input. If we cancel the
10-year review, the old outdated conditions remain in the AO. If we do what we can within the bounds of the 10-year
review, the old outdated conditions remain in the AO but some of the formatting gets updated. I think it probably makes
sense to cancel the 10-year review so things are less confusing for the source, but I already put some time into updating
the format so I'm good either way.
Let me know what you think.
Thanks,
Dungan

Hi Dungan,
I think it would make sense to issue them the 10-year update since you've already put the work into it. The source has
also been notified of the potential compliance issues with this update and seems to be fine with it.
Thanks,

Chad,
Here is the 10-year review ER for Kimball's portable AO. When we last discussed it, you mentioned the variety of the
stationary conditions (haul road lengths, storage pile sizes, disturbed area, etc.) that would cause compliance issues.
These conditions are all present in the active AO from 1992, so I don't think updating the format creates new compliance
issues. But it does keep all the problematic conditions in the AO...
I just wanted to send the ER again and confirm that it is okay to move forward. If there are any ways you think the ER can
be better updated that don't involve removing or adding requirements/limitations please let me know.

Hi Dungan,
Thanks for checking in on this one. I appreciate it. I think this looks good and can be sent through. At this point we've let
the source know about the potential compliance issues and they still opted to move in this direction. It likely won't be a
big issue since it's a portable AO but we will have to pay a little extra attention to their temporary relocations if/when they
are submitted.
Thanks again,
Chad
