Subject: Letter Report for Tank Inspection at Area M-392. Tank 2 Fca80i-56i-ia6i '
Dear Mr. Holladay: •
This letter report summarizes inspection activities conducted In behalf of Thiokol
Corporation ("Thiokor) by EarthFax Engineering, Inc. ("EarthFax") during inspection of Tank
2 in area M-392 of facilities operated by Thiokol at Promontory, Utah. Enclosed with this , •
letter report is a copy of the "Existing Hazardous-Waste Tank Inspection Form" which i
includes specific items observed in the field during inspection of the tank.
Tank 2 is constructed Of two SO-mil high density polyethylene ("HDPE") flexible membrane
liners, with the outer liner providing secondary containment protection against leaks which
might develop in the inner liner. The walls of the double liner tank are supported using
galvanized steel sheeting and galvanized steel support braces. The floor of the tank is
supported by a concrete pad upon which the tank rests. An absorbent geotextile fabric
material is placed between the two liners and serves as a 'wick' to absorb any liquids
which might accumulate between the liners due to precipitation, condensation, or liner
leakage. This wick material is a non-woven needle-punched polymeric geotextile fabric
which yveighs 1.0 ounces per square yard. The geotextile fabric between the two HDPE
liners is connected to a sump system which serves to collect any condensation,
precipitation, or liner leakage which may accumulate in the geotextile liner. This sump
system is mounted such that the lid of the sump box is at ground surface elevation-. The
sump box is estimated to hold approximately 125 gallons of water.
An inspection of this tank Was conducted on February 16, 1998. On this date, the tank
contained approximately 4 feet of water to which rhodamine dye had been added on
February 13, 1998. The pink coloration of the water at the time of inspection was
uniform throughout the tank.
During inspection of the tank, no damage due to cracking or corrosion was observed in the
structures which support the HDPE liners, including the cement pad which supports the
HDPE liners, the galvinized steel sheeting, and the galvanized steel support braces. Some
moisture was noted on the cement pad around the outside walls of the tank, but this was
due to melting snow.
As the sump box was inspected, a small amount of water (probably less than 0.10 gallons
per minute) was observed issuing from the PVC pipe. A sample of this water was
collected and was visually compared to a similar volume of water collected from the dyed
water In the tank. No pink coloration was observed in the siample of sump water. Rather,

this sample wa[S a light brown color which was likely indicative of dust which has collected
in the sump box or had been deposited on the wick material where it is exposed to the
atmosphere.
The water samples collected from the sump box and from the tank were then evaluated
using a longy/ave ultraviolet light (Blak-Ray, Model ML-49, 366 nanometers). The water
sample from the tank, which contained the rhodamine dye, shone iridescently beneath the
ultraviolet light while the vvater sample taken from the sump box did not. The purpose of
this evaluation was to determine whether trace amounts of dyed tank water (which might
not be visible to the natural eye) could be present in the sample water collected from the
sump box. Results of this evaluation therefore indicated that water issuing from the PVC
pipe in the sump box was not originating from inside the tank. Rather, they corroborate
the theory that the water in the PVC pipe was originating from condensate or precipitation
which had developed between the HDPE liners.
As a control against the possibility that diluted amounts of water tainted with rhodamine
dye might not iridesce beneath an ultraviolet light, the tank sample which had been spiked
with the dye (and had shone iridescently beneath the ultraviolet light) was diluted until the
pink coloration in the sample was not observable to the natural eye (a dilution of about
1:4, v/v). It was then placed beneath the ultraviolet light, whereupon the diluted sample
shone iridescently.
Based on our examination, it is my opinion that the tank as constructed adequately meets
the requirements of 40 GFR 265.191 for use in storage of hazardous materials.
Furthermore, the foundation soils on which the tank is installed appear to be adequate to
support the tank.

personnel properly gather ahd evaluate the information submitted- Based on my inquiry of
the person or persons who manage the system, or those persons directly responsible for
