Dear Mr. Haehl:

Re: Request for Evaluation of Compliance with Rule R307-401-9, UAC: Small Source Exemption
Project Fee Code: N162400001

On December 9, 2024, the Division of Air Quality (DAQ) received your request for a small source
exemption for Nusano, Inc.’s Radioactive Isotope Production Facility. The source is located at 4129 West Lake Park Boulevard in West Valley City, Salt Lake County. DAQ has determined the small source
exemption applies to the source, as long as the equipment and associated processes operate as specified in
the registration request and in Radioactive Materials License (RML UT1800643).

The small source exemption does not exempt a source from complying with other applicable federal,
state, and local regulations and the current Utah Administrative Code. Based on the emissions that you
submitted to DAQ with your registration request, Nusano, Inc. is not required to obtain an approval order
under R307-401 for the Radioactive Isotope Production Facility. If you change your operation such that
there is an increase in emissions, we recommend that you notify us, as an approval order may be required.

As authorized by the Utah Legislature, the fee for issuing this small source exemption is a one-time filing
fee in addition to the actual time spent by the review engineer and all other staff on the project. Payment
should be sent to DAQ upon receipt of the invoice.

Hi Kae,
Thank you for meeng with us this morning.
We definitely want to sasfy all of your quesons. Please be in touch aer you discuss with your team. We may need
your guidance to provide the informaon in the format you need.
Enjoy the weekend!

Sarah,
Thank you for sending the follow up email!
I've had a chance to speak with Alan. Based on our conversation, while it is very likely you meet the threshold
requirements for the HAPs, I am required to verify that you meet the threshold requirements in order to issue a Small
Source Exemption. With the Small Source Exemption, the DAQ would not inspect the site, issue NSR fees, or need to
know about any site modifications unless the modifications result in the thresholds being exceeded.
I believe it was Tim who said that the calculations could be taken a step further to show the emissions in lbs/year. As
radionuclides are not listed out individually on the HAPs list, I believe it will be sufficient to calculate the total sum of
radionuclides that may be emitted into the air.
Please send me the total emissions in lbs/yr of the total sum of radionuclides. Since you've mentioned that
confidentiality is important, I'd like to set up a meeting to walk through the calculations and assumptions you have used in
showing the emissions in lbs/yr.
Please let me know if you have any questions or concerns.
Happy Holidays,
Katie Andersen

Hi Kae,
Following up to let you know we haven't forgoen about this!
We've esmated the ancipated radionuclide emissions and we are working on the tank emissions. The tank
manufacturer has not been available over the holidays, but we should have the necessary data soon.
I will be out of the office next week (January 6-10), but will be in touch when I return.
Happy New Year,
Sarah

Sarah,
Thank you for the update! I will keep an eye out for those emissions in the next few weeks or so!
Cheers,

Hi Kae,
I'm back in the office this week and I am looking forward to finalizing this SSE with you.
I believe we owe you info for two topics: (1) generator diesel tank emissions and (2) radionuclide emissions.
Generator Diesel Tank. I have aached the spec sheets for the generator and its tank. The tank is a 2,100-gallon
integrated tank base. This style of tank is not well described by any of the TANKS program categories; if you would
sll like us to work out these emissions in TANKS I would appreciate your guidance.
Radionuclide Emissions. As we've discussed, our understanding is that radionuclide emissions are to be regulated by
our Radioacve Materials License (RML UT1800643) and not by the Clean Air Act as a HAP. This is based on the 1996
USEPA / NRC agreement to eliminate dual regulaon of rad emissions (40 CFR 61 Subpart I; 96-32977.pdf). Per our
RML, we will follow the guidance of NRC Regulatory Guide 4.20 to demonstrate compliance with the public dose
limits set forth in 10 CFR 20 Appendix B (Regulatory Guide 4.20, "Constraint on Releases of Airborne
Radioactive Materials to the Environment for Licensees other than Power Reactors."). Our RML will specify
configuraon of our facility venlaon system (including carbon and HEPA filters) and will require connuous air
monitoring.
You've asked for the PTE of radionuclides as HAPs. Our RML maximum possession limits will allow for approximately
0.2 lbs of radioacve materials to be on site for processing at any one me. Even if we consumed that complete
inventory every day of the year and emied 100 percent of materials directly to the air, our radionuclide emissions
would be < 75 lb/yr. Of course, this is a gross over-esmaon and assumes that we make no product at all with these
materials and have no emissions controls. In reality, we expect radionuclide emissions to be on the order of < 1
gram/yr. This value is consistent with similar accelerator facilies and will be confirmed by our air monitoring.
Please let me know what other informaon you need to register the SSE. I am available for a phone call any day this
week or next.
Best,
Sarah
