RE: Addendum to the Part B Class 3 Permit Modification Request and Temporary
Authorization #MOD98.00729
EPA ID #UTD009081357
Dear Mr. Thompson:
This letter is in response to Thiokol's requested addendum to the Class 3 Permit Modification
request, previously submitted on December 22, 1997. This addendum was received by the Division
of Solid and Hazardous Waste by FAX on July 20, 1998 and addresses the disassembly of rocket
motors prior to open buming.
The modification request of December 22, 1997 addressed only the storage of rocket motors. With
this addendum, however, Thiokol intends to modify its storage permit to allow storage and treatment
of rocket motors for demilitarization projects, since the disassembly process meets the definition of
hazardous waste treatment.
On March 13, 1998, Thiokol was granted a Temporary Authorization pursuant to 40 CFR 270.42(e)
to store Sprint rockets at the Promontory Facility. This Temporary Authorization expires on
September 14, 1998. The July 20, 1998 addendum also requested that this temporary authorizafion
be expanded to include the treatment (disassembly) ofthe rocket motors.
Based on the information received in the addendum and the subsequent information submitted on
July 21, 1998, also by FAX, Thiokol's request to include treatment in the Class 3 Permit
Modification request of December 22, 1997 and the Temporary Authorization of March 13,1998
is hereby approved.
Thiokol must conduct the authorized storage and treatment activities in accordance with the
provisions oufiined in the Class 3 Modificafion Request and the letter of July 21, 1998, and in
compliance with all applicable standards of 40 CFR Part 264 for the term of the Temporary
Authorization.
It its acknowledged that Thiokol will comply with the notification requirements of 40 CFR
270.42(c) as stated in the July 20, 1998 addendum request. Receipt of the $1000.00 permit
modification fee is also acknowledged. This Class 3 Modification has been assigned tracking
number 98.02877. Please use this number in all future references to this modification. References
to the Temporary Authorization should include its assigned tracking number, 98.00729.
Ifyou have any questions regarding this letter, please contact JeffVandel at 538-9413.
Sincerely,
