RE: Utah Hazardous Waste Emergency Permit UT-057-2006
ATK Thiokol Inc. – Promontory Facility
EPA I.D. #UTD009081357

Dear Mr. Gosen:

On Saturday, September 23, 2006, ATK Thiokol contacted Jeff Vandel of my staff to request an emergency permit for the treatment of hazardous waste, by detonation, at building M-188.
Based on the information that was provided, oral approval for the emergency permit was granted and the detonation was conducted on the morning of September 24, 2006. A written request
for the emergency permit was received by the Division of Solid and Hazardous Waste on September 25, 2006.

According to the information that was provided by members of your staff, an unplanned explosion occurred at building M-188 on Friday, September 22, 2006 at approximately 3:30 pm. It
was reported that approximately 680 pounds of energetic material exploded in the accident that occurred in Bays #1 and #2 of the building. During an examination of the building after
the blast, it was discovered that additional, un-reacted material remained in Bay #4. As a result of the blast, this material was covered with a portion of a concrete wall and other
rubble. As stated in your letter, ATK’s Incident Response Team determined that the un-reacted, energetic material was unsafe to move, and that the only safe way to manage the material
was to detonate it in-place. An emergency permit was required so that the un-reacted, energetic material, now characterized as a hazardous waste, could be treated by detonation at the
building.

Enclosed is Utah Hazardous Waste Emergency Permit #UT-057-2006 providing Thiokol authorization for the treatment of hazardous waste as described above. This permit, which is based on
the information provided by Thiokol, became effective on September 23, 2006 and
September 28, 2006

expired on September 25, 2006. Emergency permits are issued under the authority of 19-6-101 through 105, Utah Code Annotated, as amended and R315-3-6.2.

It is stated in your letter that the treatment (detonation) was successful and the reaction of the energetic hazardous waste appeared to be complete. In addition, it is stated that
ATK Thiokol will submit a follow-up letter to the Division after further investigation is complete. The Division requests that ATK Thiokol provide a post-treatment report that will
include the following information: a description of the final cleanup of the site, the management of waste materials generated as a result of the treatment, and an assessment of the
release of hazardous constituents to the environment. Please submit the post-treatment report no later than seven days after cleanup of the site is complete.

If you have any questions, please contact Jeff Vandel at 538-6170.

Sincerely,
