Dear Erin Dunman:

RE: Revocation of Approval Order DAQE-AN0142630001-10 dated March 8, 2010
Project Number: N142630002

The Division of Air Quality (DAQ) received your request to revoke Approval Order (AO)
DAQE-AN0142630001-10 on June 6, 2024. Wyoming Interstate Company has requested that this AO be
revoked due to the facility permanently ceasing operations. The DAQ has revoked the above-referenced
AO effective as of the date of this letter.

As authorized by the Utah Legislature, the fee for revoking an AO 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 Lucia Mason, who can be reached at [phone] or
[e-mail].

Sincerely,

{{$s }}
