Dear Mr. Huntoon:

RE: Revocation of Approval Order DAQE-AN123210011-15 dated October 21, 2015
Project Number: N123210014

The Division of Air Quality (DAQ) received your request to revoke the above-referenced Approval Order
on April 26, 2024. DAQ has determined that Honeywell Electric Material’s - Titanium Refinery is
exempt from the requirement of needing an approval order because it qualifies for a small source
exemption under Utah Administrative Code (UAC) Rule R307-401-9.

The DAQ has revoked the above-referenced Approval Order effective as of the date of this letter.

As authorized by the Utah Legislature, the fee for revoking an Approval Order is the actual time spent by
the review engineer and all other staff on the project. Payment should be made to the DAQ upon receipt
of the invoice.

If you have any questions, please contact Stockton Antczak, who can be reached at [phone] or
[e-mail].

Sincerely,

{{$s }}
