Dear Mr. Hansen:

On January 29, 2024, the Tooele Army Depot North Area (TEAD-N) verbally
notified the Utah Division of Waste Management and Radiation Control (UDWMRC) that
an emergency permit was required to open detonate compromised explosive items. The
compromised items consist of 141 High Explosive 3.5-inch Rockets. TEAD-N received
verbal approval from Adam Wingate, a member of your staff, on February 1, 2024. The
emergency permit granted for this operation is UT-002-2024.

During routine inspection, these items were found to be suspended due to the
possibility that Cubric Azide compounds have formed in the fuzes and deemed unsafe
for storage. They will be detonated near their current storage igloo, C506, by The Air
National Guard Explosive Ordnance Disposal (EOD). The detonations will occur
between the days of February 12 – February 23. The total net explosive weight,
including donor, that will be detonated is approximately 468.888 pounds.

Should you have any questions regarding this matter, please contact Jay Nelson,
a member of my staff, at [phone].

Respectfully,

Erin Trinchitella
