OPERATING STATUS: The asphalt and concrete plants were operating normally at the
time of inspection.

PROCESS DESCRIPTION: Asphalt Plant: Sand and gravel are transferred from the
aggregate crushing plant to the asphalt batch plant by a front-end
loader and dumped into the asphalt plants compartment feeder
bins. The sand and gravel are air classified prior to the asphalt
binder being added. Asphalt binder is hauled to the site from
various refineries in tanker trucks and off-loaded into the hot oil
heat exchanger. Lime is trucked in from off-site and
pneumatically loaded into the plant's storage silo. Sand and
gravel aggregates are batched by weight from the feeder bins
onto a conveyor belt and transported to the pugmill. Inside the
pugmill, aggregates are mixed with lime. The lime/aggregate
mixture is conveyed through a natural-gas fired, ASTEC double
barrel counter flow dryer/mixer. If Recycled Asphalt Product
(RAP) is being used, it is dumped into the RAP feeder bin and
conveyed directly into the dryer, bypassing the pugmill. The
dried lime/aggregate mixture and RAP then enters the outside
barrel. The lime/aggregate and/or RAP is mixed with asphalt
binder to create asphalt. The asphalt exits the rotary dryer/mixer
and is conveyed up a bucket elevator to the scalper screen. Any
oversize from the scalper screen is fed into a reject bin. The
asphalt passing through the screen is fed into hot mix storage
silos. The asphalt is gravity fed into haul trucks from the silo and
hauled to the construction site.

Recycled Asphalt Product (RAP): RAP is shipped by truck and
offloaded in the yard. It is crushed and screened in the recycle
crushing circuit. Chunks of asphalt are fed by a front-end loader
into a vibrating feeder/grizzly and then conveyed to a crusher.
From the crusher the material is conveyed to a triple deck screen,
which either feeds material to a jaw crusher, back to the impact
crusher, or to a final product storage pile. Material from the
storage pile is transported by a front-end loader to the RAP
feeder bins for use in the asphalt plant. Material fed to the jaw
crusher is conveyed back to the triple deck screen.

Aggregate Plant: All permitted aggregate equipment has been
removed from this site except for the wash plant. The source is
operating a temporary aggregate plant with a 1000-kW generator
(see TRP DAQC-710-24).

Concrete Batch Plant: Water is put into the delivery mixer
trucks. Washed sand and gravel from the aggregate wash plant is
loaded into separate bins and drops into the weight hopper at the
correct mix. Dry cement from the cement silo drops into the
weigh hopper prior to being discharged into the mixer truck. All
mixing of the product is done en route to the job site.

Good morning Daniel,

I’m the Staker Parson Environmental Specialist serving Western Rock among other facilities, and I wanted to let you know
that I received your request for information following your visit to our Cedar City facility, and I apologize for my late
response; I’ve been traveling since late last week. I have been compiling a folder of documentation that will fulfil all your
requests. I am still waiting on specifics for hours of operation, but I should have all the information you need by early next
week if I can’t swing EOD.

I just wanted to follow up and let you know that I’ve been working on this despite my lack of communication with you. FYI,
I am the environmental contact for all of Western Rock Products, Hales Sand and Gravel, and our central and southern
Staker Parson and Jack B. Parson facilities. Please let me know if there’s anything else I can do.

Thank you,

Good morning Daniel,

Thank you for your continued patience on this project. I have compiled everything that I have access to,
although there are some points that unfortunately I won’t be able to provide documentation for. To mitigate
this issue in the future, I have provided the Cedar City operators with a comprehensive documentation
master log that will make total recordkeeping much easier for them.

As I may have explained, I’m new at the company but I look forward to helping the operators make strides in
recordkeeping.

I have attached all files relevant to your search. Please let me know if you have any questions.

Chris - just a few questions for clarification:
For Condition I.8 - Technically, this was due July 23, 2020, but I do not see it in your source file. Can you send an official
document to satisfy the requirements of this condition? A short paragraph will suffice.
For Condition II.B.2.b - do you have similar verification that any aggregate processing from November 2023 and
December 2023 did not occur outside of these times like you sent me for the HMA plant (6 am - 9 pm)?
For Condition II.B.3.b - same as above for the concrete plant, except between 6 am and 4 pm
For Condition II.B.3.f - the spreadsheet you sent me includes November 2023 - April 2024. Does that mean the hot water
heater was not run at all from June - October 2023, or in May 2024?
For Condition II.B.4.a - can you show that the haul roads and loader operation areas do not exceed these limits?
Do you have a OOO initial performance test for Method 9 for the temporarily relocated aggregate plant and its associated
equipment?
Finally, do you keep records of water spray nozzle inspections or is there a policy on site for a frequency of these
inspections? 40 CFR Part 60 Subpart OOO requires monthly nozzle spray inspections. This is usually included in the
conditions of the AO as well, but it was not explicitly stated in this permit.
Best,
Daniel

Daniel,

Thanks for reaching back out. I have site visits scheduled throughout this week, so I’ll be able to answer
these questions for you, but it may not be till later this week or next.

I’ll revisit these questions with our site managers, but in for the sake of transparency, I won’t be able to
provide clarification for every one of these questions. I’m new at the company and as a result of your initial

Daniel,

Sorry for the delay. Here’s what I could find out for you:

I’ve attached a short note on letterhead providing verification that we did install and start operating the
permitted equipment within 18 months of AO issuance.

For condition II.B.2.b, I don’t have verification that aggregate processing didn’t happen outside of the
restricted operation times.

For condition II.B.3.b, we must have the data somewhere, but I haven’t been able to pull it yet. I’ll get back
to you very soon on this.

For condition II.B.3.f, you’re correct. The hot water heater is only run in the colder months to my knowledge.

For condition II.B.4.a, unfortunately I don’t have the verification to show that the haul roads and loader
operation areas meet the length requirements.

For the temporary aggregate equipment, are you referring to the plant that relocated to the site last month?
The only other portable we’ve had there recently according to my notes was approved in Aug 2022.

Lastly, we do keep record of our spray nozzle inspections. Before firing up, the plant foreman completes a
pre-shift inspection, one point of which is dust suppression nozzles. Therefore, the spray nozzles are
inspected on a daily basis as per our MSHA workplace daily inspections.

I’ll get back to you ASAP about the RMC operating hours, I’m sure we both want to close out the site
inspection.

Let me know if you have any additional questions regarding any of my other points,

Thanks for the reply. Let me know when you're able to provide information for Condition II.B.3.b
For the haul road and loader operation areas, sources will often use Google Earth to measure the distances. If you could
provide an image of the haul roads and the loader operation areas showing their lengths with a scale, that would suffice
for this requirement. If the lengths exceed these limits, then you'll need to request a modification to your AO to either
remove this condition or change the limits.
For the temporary aggregate equipment, see the attached temporary relocation permit. If the temporary aggregate plant
has any screens, crushers, and conveyors manufactured after 2008, these need to be evaluated for OOO compliance.
Could you send a couple of days example of what the preshift inspection looks like?

Daniel,

I apologize- I assumed since you asked for records through May ’24 you wouldn’t need to see anything
relating to the newest temp crusher, which moved there a couple months later. We inspect all applicable
subpart OOO equipment on the portable crusher, so I’ll send proof of that. We aren’t running all the
aggregate equipment on the AO, but I’m having the foreman scan and send over a few days of pre-shift
inspection forms for what we are running.

After talking with our managers at the site it looks like we haven’t been recording the start stop times of the
aggregate and batch plants, we just record total operating hours for the plants. Since the RMC is limited to 6
AM to 4 PM in the winter and aggregate 6 AM to 9 PM, I can provide proof that the RMC never operated
over 10 hours a day and aggregate 15 hours a day, just not the actual timestamps. Since your inspection
this summer I’ve implemented requirements for the managers to start logging on/off times.

For the portable crusher that was recently moved to the site, we haven’t done the initial VEOs yet. We’ll
make sure to conduct initial VEOs within the allotted 60 days of startup.

After mapping the haul roads and loader operation areas, unfortunately it seems as though we have gone
over our length requirements. I will be working to submit an NOI very soon to update the Cedar City AO
accordingly. As I’ve mentioned to you before, we strive to remain compliant; I’m happy to try and expedite
any way to achieve that.

I’ll reach back out with the daily pre-shift inspections soon.

Daniel,

Although we visually inspect the dust suppression on a daily basis, we only document it on the monthly
inspection sheets. I’ve attached an example copy of our latest August monthly inspection sheet for one of
our pieces of equipment.

Let me know if you have any questions,

Thanks for sending this monthly example and for asking your staff to start logging on/off times on the equipment.
I believe now I just need verification that hours were < 15 during winter months for the agg plant, < 10 during winter
months for the concrete batch plant, and then could you provide me with the calculations you made for Condition II.B.4.a?
What would be the best mailing address for certified mail from the DAQ? Should I address it to you, or someone else? I
need to confirm with my manager, but we will likely issue a Warning for the haul road and operation area exceedances.

Daniel,

The calculations I landed on for haul roads were the following:

HMA and mixer haul roads were a total of exactly 1,900 feet. Aggregate haul roads were a total of 2,355.2
feet. Together the truck haul roads were 4,255.2 feet long. I calculated that the loader operation areas were
821.8 feet. I have an attachment with the mapped routes- pink for aggregate haul roads, green for HMA and
RMC haul roads, and yellow for loader operation.

I’ve attached our aggregate KPI report to this email. The number you’re looking for is in the “actual
operating time” column. This is proof that we didn’t run over 15 hours a day between 11/1/23 and 3/31/24.
We did not have any aggregate processing after December as you can see from the query at the top of the
report.

We don’t currently have as slick of a way to pull RMC operation times, but we do log the water heater hours
for the plant. This will show the operating hours per day plus a little extra with startup and shutdown time for
the heater. This is proof that RMC operations didn’t occur over 10 hours a day between 11/1/23 and
3/31/24.

This should be everything that you need to close out your inspection. Please let me know if you have any
additional questions.

Thanks Chris. The DAQ will be sending out a Compliance Advisory for the exceedance in haul road length to the address
you provided. The reason these limits are important is they are included in the AO to ensure PM fugitive emissions do not
exceed the NAAQS. Once the Compliance Advisory arrives, you'll have ten business days to provide a formal response
and the DAQ will move forward based on that response. Please email your response to me and cc Chad -

Daniel,

Although we visually inspect the dust suppression on a daily basis, we only document it
on the monthly inspection sheets. I’ve attached an example copy of our latest August
monthly inspection sheet for one of our pieces of equipment.

Let me know if you have any questions,

Daniel,

I apologize- I assumed since you asked for records through May ’24 you wouldn’t need
to see anything relating to the newest temp crusher, which moved there a couple months

later. We inspect all applicable subpart OOO equipment on the portable crusher, so I’ll
send proof of that. We aren’t running all the aggregate equipment on the AO, but I’m
having the foreman scan and send over a few days of pre-shift inspection forms for what
we are running.

After talking with our managers at the site it looks like we haven’t been recording the
start stop times of the aggregate and batch plants, we just record total operating hours
for the plants. Since the RMC is limited to 6 AM to 4 PM in the winter and aggregate 6
AM to 9 PM, I can provide proof that the RMC never operated over 10 hours a day and
aggregate 15 hours a day, just not the actual timestamps. Since your inspection this
summer I’ve implemented requirements for the managers to start logging on/off times.

For the portable crusher that was recently moved to the site, we haven’t done the initial
VEOs yet. We’ll make sure to conduct initial VEOs within the allotted 60 days of startup.

After mapping the haul roads and loader operation areas, unfortunately it seems as
though we have gone over our length requirements. I will be working to submit an NOI
very soon to update the Cedar City AO accordingly. As I’ve mentioned to you before, we
strive to remain compliant; I’m happy to try and expedite any way to achieve that.

I’ll reach back out with the daily pre-shift inspections soon.

Thanks for the reply. Let me know when you're able to provide information for Condition II.B.3.b

For the haul road and loader operation areas, sources will often use Google Earth to measure the
distances. If you could provide an image of the haul roads and the loader operation areas showing
their lengths with a scale, that would suffice for this requirement. If the lengths exceed these limits,
then you'll need to request a modification to your AO to either remove this condition or change the
limits.

For the temporary aggregate equipment, see the attached temporary relocation permit. If the
temporary aggregate plant has any screens, crushers, and conveyors manufactured after 2008,
these need to be evaluated for OOO compliance.

Could you send a couple of days example of what the preshift inspection looks like?

Daniel,

Sorry for the delay. Here’s what I could find out for you:

I’ve attached a short note on letterhead providing verification that we did install and
start operating the permitted equipment within 18 months of AO issuance.

For condition II.B.2.b, I don’t have verification that aggregate processing didn’t happen
outside of the restricted operation times.

For condition II.B.3.b, we must have the data somewhere, but I haven’t been able to
pull it yet. I’ll get back to you very soon on this.

For condition II.B.3.f, you’re correct. The hot water heater is only run in the colder
months to my knowledge.

For condition II.B.4.a, unfortunately I don’t have the verification to show that the haul
roads and loader operation areas meet the length requirements.

For the temporary aggregate equipment, are you referring to the plant that relocated to
the site last month? The only other portable we’ve had there recently according to my
notes was approved in Aug 2022.

Lastly, we do keep record of our spray nozzle inspections. Before firing up, the plant
foreman completes a pre-shift inspection, one point of which is dust suppression
nozzles. Therefore, the spray nozzles are inspected on a daily basis as per our MSHA
workplace daily inspections.

I’ll get back to you ASAP about the RMC operating hours, I’m sure we both want to
close out the site inspection.

Let me know if you have any additional questions regarding any of my other points,

Daniel,

Thanks for reaching back out. I have site visits scheduled throughout this week, so
I’ll be able to answer these questions for you, but it may not be till later this week or
next.

I’ll revisit these questions with our site managers, but in for the sake of
transparency, I won’t be able to provide clarification for every one of these
questions. I’m new at the company and as a result of your initial inspection
information request, I’ve enacted recordkeeping improvements to aid in clarity
during inspections.

I’ll reach out soon with an answer for everything you’ve requested clarification on.

Chris - just a few questions for clarification:

For Condition I.8 - Technically, this was due July 23, 2020, but I do not see it in your source
file. Can you send an official document to satisfy the requirements of this condition? A short
paragraph will suffice.
For Condition II.B.2.b - do you have similar verification that any aggregate processing from
November 2023 and December 2023 did not occur outside of these times like you sent me for
the HMA plant (6 am - 9 pm)?
For Condition II.B.3.b - same as above for the concrete plant, except between 6 am and 4 pm
For Condition II.B.3.f - the spreadsheet you sent me includes November 2023 - April 2024.
Does that mean the hot water heater was not run at all from June - October 2023, or in May
2024?
For Condition II.B.4.a - can you show that the haul roads and loader operation areas do not
exceed these limits?

Do you have a OOO initial performance test for Method 9 for the temporarily relocated
aggregate plant and its associated equipment?
Finally, do you keep records of water spray nozzle inspections or is there a policy on site for a
frequency of these inspections? 40 CFR Part 60 Subpart OOO requires monthly nozzle spray
inspections. This is usually included in the conditions of the AO as well, but it was not explicitly
stated in this permit.

Best,
Daniel

You don't often get email from [e-mail]. Learn why this is important
issue in the future, I have provided the Cedar City operators with a
comprehensive documentation master log that will make total recordkeeping
much easier for them.

As I may have explained, I’m new at the company but I look forward to helping
the operators make strides in recordkeeping.

I have attached all files relevant to your search. Please let me know if you have
