Daniel,

I have attached the documents requested.
I have equipment hours set up as a weekly, and monthly. Going by the weekly, you will notice the totals are mostly showing less than a 40-hour
week.
Although the employees may work 8-9 hours a day, the equipment is operated less due to daily maintenance taking 1-3 hours daily (depending if
repairs are also needed.).
There is a map showing the distance from the gate to the entrance of the pit (1.08 miles). Add the distance to drop into the pit and circle back out
would be just shy of 1.25 miles.
The total sum of hours can be found on either the weekly or monthly sheets at the bottom of each column.
The delivery ticket for the load of fuel delivered just prior to the inspection (showing ultra-low sulfur) has been attached.
There is no performance test for the VSI and its double deck screen. We have not put that equipment into production, only intermittent testing (as
shown on the equipment hour spreadsheets).
We have not been able to produce a product within the specs we need. We are also waiting on the new AO from UDAQ.

Dennis - a few questions regarding your records:
1. For Condition II.B.1.b - D) - do you have any record to show that operation did not occur more than 8 hours per day, 5 days per week from
December 21, 2023 - March 21, 2023? Or can you demonstrate that no work was performed?
2. Do you have OOO initial opacity observations for any of your new equipment? This was also noted as missing in the CA issued on August 23,
2024.
3. Re the above CA, I just wanted to remind you that an official response to that document is due within 10 days of receipt of the letter.
Thanks and let me know if you have any questions,
Daniel

Daniel,

Answer to questions:
1. Our company does not work more than 8 hours a day (40-hour work week). As far as demonstrating, you can look at the monthly hours and
divide them by the number of week days in the month to verify we had not gone over 8-hours per day.
The 910 KW generator went past the h 8-hour period for 2 days (total of 3 hours) due to maintenance being performed by caterpillar on this
generator.
2. We do not have any opacity readings on the new equipment sue to not only being used for testing (not having an actual start-up).
3. As far as answers to the above CA, they were sent VIA USPS overnight on Friday, August 30, 2024). They should’ve been in your offices no
later than Monday the 2nd in the AM hours.

‘ll be sending an email to find out where our AO is due to the modeling was approved on May 14, 21024. The AO should have been totally approved
and returned to us at least a month prior to your inspection, and we would have sent a letter of intent to start up and testing performed.

I found the CA response in our inbox. Thank you for sending that. I'll be coordinating with Susan Weisenberg, who did your 2023 inspection, and my
manager Chad Gilgen on the DAQs next steps for any potential compliance action.

Dennis,
An Early Settlement Agreement (ESA) from the DAQ will be sent out today, and you can expect that through certified mail. It will address the non-
compliance that I observed on July 18, 2024, as well as the non-compliance my coworker Susan Weisenberg observed on May 25,2023. Please let us
know if you have questions.
Best,
Daniel

Daniel,

We did receive the leer on the 5th of this month.
I do have a queson. The leer states it is based on this year and the previous year.
How am I supposed to know which citaon is from which inspecon?
I have a citaon for no inial performance on new equipment, then another citaon for no performance tesng on engines over 500 HP.
I am trying to figure out which citaon is for what piece of equipment.

Thank you,

Dennis,
My colleague Susan Weisenberg had issued a Compliance Advisory (attached) to you based on her inspection in 2023 which was never resolved.
This ESA was written to encompass both her and my compliance actions. Performance testing for new equipment is an opacity reading required by
40 CFR Part 60 Subpart OOO, whereas the performance testing for generators is a stack test required by 40 CFR Part 63 Subpart ZZZZ. If you'd like
to discuss the ESA, we could arrange a virtual call to set that up.
Best,
Daniel

I don’t believe that I’ve ever seen this one. For some reason it Looks like it was sent to Mountain America credit union, then shows it should have
been delivered to us, but again I've never seen it.
I believe we need to meet on these due to me not knowing about the first one, and I would like to know more information on the second one.
I can meet or do a video conference on the 23rd if you would like to send me an invite.
