Dear Mr. Bradshaw:
RE: Revocation of Approval Order DAQE-AN161850002-24 dated January 8, 2024
Project Number: N161850003
Bradshaw Farms & Equipment was issued an Approval Order (AO) referenced above to conduct rock
excavation and crushing operations. The source will be excavating a pond to settle out particulates in the
irrigation water. The rock that is excavated will be crushed on site via one (1) crusher and used as a road
base in the same area. The source anticipates its operations to only last two (2) weeks and the volume of
excavated rock to not exceed 10,000 cubic yards. Emissions from the operations fall under the thresholds
for a small source exemption. Therefore, the Division of Air Quality (DAQ) has revoked the AO
referenced above as of the date of this letter. A Small Source Exemption will be issued in a separate
letter.
If you have any questions, please contact Katie Andersen who can be reached at (385) 515-1748.
Sincerely,
{{$s }}

Katie,
Can you please process this project? This will be a small source exemption and a permit revocation. The source
submitted the wrong type of permit application and we issued a portable AO instead of a SSE. You will need to estimate
the emissions yourself to confirm the source meeting the SSE thresholds. You can use the spreadsheets on our website
to estimate emissions. We will also not bill the source for this work. Please update the letters to reflect this when you
issue them.

Please let me know if you have any questions.
Thanks,
Alan

Hello Alan,
We are local farmers working on building a pond on our rural farm to settle sentiment out of the water before it goes
into the irrigation pipes. When building the pond, we decided to crush the rock, that is dug out of the hole for the pond, to
use as road base. The crushing is in a very remote area, away from residential houses, and would be a ONE time thing
only lasting about 2 weeks. The amount of rock that will be crushed is around 10,000 yards. We completed the public
comment period at the local zoning and planning meeting and received approval to do the project, upon receiving an air
quality permit. Once again, this project is a one time thing only lasting a couple of weeks and is basically a process to "kill
2 birds with 1 stone" because we would be digging the rock up anyways, so we decided to crush it and use it for road
base in the same area. This being our first time submitting for an air quality permit, I called the air quality permit division
and talked with Eq, and was directed to fill out the application that I submitted. I was a bit surprised at the process,
because this is a very small one time project, but I figured that was part of the process because I had called and was
directed to fill out that certain application. The process took over 3 months and was more involved than expected. Being
the first time applying for this type of permit, I assumed this must be the normal process even though it seemed much
more involved than necessary. Once everything was finally completed and approved, I received a bill for almost $3,000! I
was quite shocked! As mentioned earlier, this was my first time going thru this process and I had called and received
direction that I followed. This cost a lot of unnecessary time and money. Because of the direction I received, from the air
quality permit personnel, I feel that I was misled and lost time waiting for the completion of a permit that was not
necessary when another type of permit would have been sufficient. I had no idea the cost would add up so quickly, and
there was no quote given before the process was started, to notify us of the cost. Because of all these factors, this is what
I am hoping we can accomplish:
1. I would like to know what the correct application is to fill out and find out what that cost would be.
2. I would like to know if it's an option to not to be charged for the first permit as it is much more than what is necessary
for the project.
We appreciate the help and work that has been done so far and would like to be get everything worked out and the right
permit granted. Thank you for your time and I look forward to your response. Please reach out with any questions or for
further clarification.
