Mr. John Holladay, a member ofthe Thiokol Environmental Services staff, spoke with Brad
Maulding and Otis Willoughby on 10 July 1996 conceming this contamination. Two major
concems were discussed, 1) whether reporting requirements are applicable ifthe process
water is spilled, and 2) if Thiokol may continue to use the water for process and fire fighting
purposes.

Brad Maulding expressed the opinion that reporting is not necessary at the low levels present
in the process well. He also indicated that these low levels did not appear to be a threat to
human health or the environment, and Thiokol may continue to use the well for firefighting
and nonculinary processes.
Thiokol plans to continue periodic sampling ofthe well and will continue to keep your staff
informed if conditions in the well significantly change. Please contact me at 801 863-8406 if
you have questions or need additional information.
Sincerely,
J. R. Whimpey, Manager
