Dear Mr. Downs
Subject: Request for renewal of RD&D Permit dated June 16, 1994 for Thiokol
Corporation EPA # UTD009081357
Thiokol Corporation requests a one year renewal of our RD&D Permit as authorized in 40 CFR
270.65(d) to complete our study of Solid Rocket Motor Disposal (SRMD). This renewal is
needed to allow a more thorough study and gain additional processing data which will help us
make a reasonable decision on the feasibility of such a process on a larger scale.
As you may be aware, we have only recently been able to begin processing our first full scale
motor because of construction, permit and tank certification delays. Our first attempt at
cryogenic washout resulted in a flash which delayed the processing even more during the
investigation into the cause ofthe flash. This investigation is not yet complete, and will
detennine ifthe washout portion ofthis operation continues.
Despiteour inability to predict the fiiture of the project at this time; we are submitting this
request to allow ample time for the State to review the request and hold public meetings if
required. If you have any questions or need additional clarification, please contact Gene Curtis at
863-4479.
