Subject: Notification of Treatability Study at Thiokol
Corporation's T-93 facility for 1.3 Propellant, EPA#
UTD009081357
Dear Mr. Downs
Thiokol Corporation is continuing to develop the technology to
remove rocket motor propellant through cryogenic wash out
techniques. The RD&D permit that was secured last year allows
us to remove propellant from full scale 1.1 motors as part of
this research. While research in this area is continuing in
compliance with our permit, we desire to conduct similar
studies with 1.3 materials.
This letter is intended to inform you of our intent to conduct
a treatability study to determine the safety aspects
associated with the removal of class 1.3 propellants using the
cryogenic process. The research with 1.3 material will be
conducted under full compliance with 40 CFR 261.4(e) and (f)
and will be performed at T-93.
If you have any questions regarding this treatability study,
please contact Gene Curtis at 863-4479.
Sincerely
(2' !<!ii3i';(V'
