PUBLIC INFORMATION
The Thiokol Corporation submitted to the Division of Solid and Hazardous Waste (DSHW)
a Class 3 permit modification for its Hazardous Waste Storage Permit on December 22,
1997. The Thiokol Corporation requested modifying its 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. The
treatment activity involved disassembly ofthe rocket motors to prepare them for disposal
by open burning. The DSHW considered 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. An initial public
comment period for the modification request was held by the facility as well as a public
information meeting. After the DSHW made the determination to issue a draft approval of
the modification request, the DSHW held another public comment period as well as a
hearing. Final approval ofthis modification request became effective March 15, 1999. For
further information regarding this modification, contact Jeff Vandel at [phone].
