Dear Ms. Burton:

Re: Hill Air Force Base, Utah Test and Training Range (UTTR) – Request for One (1) Open
Detonation of Small Quantity Hazard Class 1.2. Condition II.B.2.a – Box Elder County

Condition II.B.2a of the Title V permit #300036004 states:

“If a propellant or a munition that is not a Hazardous Class 1.1, 1.3 or 1.4 is to be
detonated or burned prior approval must be obtained from the Director.“

On March 6, 2024, the Division of Air Quality received an electronic letter requesting approval to
open detonate small quantities (less than 1 pound per event) of Hazard Class 1.2 on an occasional
basis (less than 4 times per year). The items requested for immediate disposal for safety reasons
are two (2) 10 pound net explosive weight rocket igniters. Hill Air Force Base is hereby approved
to perform this small quantity open detonation as described in your letter. This approval is valid
for calendar year 2024.

If you have any questions, please contact Joe Rockwell at [e-mail] or 385-226-3738.
Please refer to the DAQC number in the upper right corner of this letter when contacting our
office.

Sincerely,

Bryce C. Bird
