Subject: Closure of Waste Motor Storage Buildings
During a review of our permitted storage buildings, it has come to our attention, that
several of these buildings are not in use, and in fact have never been used for storage of
waste motors/propellant as permitted. Therefore, ATK Thiokol is giving the State 45
days advance notice of our intent to close the following buildings: M-107, S-616, and M-
340.
The closure plans for these buildings are identical, and require sweeping the floor, visual
inspection, then additional work only if signs of propellant contamination exists. It also
includes a closure certification requirement, by a professional engineer.
These buildings have, and will continue to store non-waste motors. Of these three
buildings, only S-616 has been used to store waste rocket motors (Sprint Motors). Since
these motors are solid structures, we believe no contamination has occurred, and request
a waiver from the requirements to have aPE certified closure. We believe after the
State's inspection of these buildings, you will be confident that no additional work is
needed to clean close these buildings.
Please let me know if you have any questions or would like to schedule an inspection of
these buildings. I can be reached at [phone], or you may contact Gene Curtis at
[phone].
Sincerely
