RE: Class 3 Storage Permit Modification #MOD98.02877
EPA I.D. #UTD009081357
Dear Mr. Thompson:
On December 22,1997, Thiokol first requested to modify its Storage Permit to authorize the storage
of waste solid rocket motors, add eight EPA hazardous waste codes, and revise permit conditions
in the Waste Analysis Plan and Inspection Schedule. On July 20, 1998, Thiokol submitted an
addendum to the permit modification request to authorize treatment of solid rocket motors (that are
characterized as hazardous waste) in addition to storage. Based on information provided by Thiokol,
the treatment activity involves disassembly ofthe rocket motors to prepare them for disposal by open
buming. The Division of Solid and Hazardous Waste (the Division) considers the disassembly
process to be treatment of hazardous waste. Thiokol also requested to add five more EPA waste
codes to the list of hazardous wastes it is authorized to store in containers at the facility.
On March 16, 1998, the Division granted Thiokol Temporary Authorization to store solid rocket
motors while the permit modification request was processed. This Authorization was reissued and
expanded to include treatment of rocket motors on September 17, 1998. The Temporary
Authorization expired on March 15, 1999.
A public information meeting was held by Thiokol on September 2,1998 at the Brigham City Public
Library to explain the proposed permit modification and to answer questions. Associated with the
meeting, Thiokol conducted a 60-day public comment period that began on July 29,1998, and ended
on September 29, 1998. Bear River City Mayor, Steve Holmgren, attended the public information
meeting and asked for a summary of the contents of the permit modification. He was provided with
a summary and his questions regarding the health risk to surrounding communities were addressed.
No other comments were received from the public.

The Division prepared a draft permit modification after the 60-day public comment period expired.
The Division then initiated a 45-day public comment period which began on
January 27, 1999. A public hearing associated with the comment period was held by the Division
on March 3, 1999 at the Brigham City Public Library in Brigham City, Utah. No one attended the
hearing, and no comments were received from the public. The public comment period ended on
March 13, 1999.
With this letter, the Class 3 Permit Modification is hereby approved as it appears in the draft that
went out for public comment, and as agreed upon by staff members of the Division and Thiokol.
Approval of the permit modification became effective on March 15, 1999.
Enclosed with this letter are the revised Modules and Attachments of the permit that were affected
by the modification. A new module (Module IV - Miscellaneous Units) is included in the permit
modification to address the disassembly of solid rocket motors.
Ifyou have any questions regarding this letter, please contact Jeff Vandel at 538-9413.
Sincerely,
Dennis R. Downs, Executive Secretary
Utah Solid and Hazardous Waste Control Board
