At the time of this report, Thiokol has a contractor on site providing sampling support
for investigation activities for several SWMU sites for the RCRA Facility Investigation.
In addition, closure activities at the M-225 Burning Ground are nearing completion,
and remediation of the SWMUs covered under Thiokol's CAMU designation is
progressing. A brief description of these activities follows.
Closure of Old Open Buming Sites at M-225
Closure activity is continuing for several of the old open burning trays at the M-225
Burning Ground (SWMU No. 19). Closure is following the approved closure
procedures found in Closure Plan for Old Open Burning Sites at the M-225 OB/OD
Facility. The sampling phase of the closure is complete, and a risk assessment has been
prepared for the residual contamination above background levels. The closure report
and risk assessment will be submitted in the very near future.
Thiokol's Corrective Action Management Unit
Additional contaminated soil has been excavated from the photographic waste discharge
sites at M-39, M-19A and M-636. This action was taken after verification samples
revealed constituents above the action levels specified in the CAMU plan. All
contaminated soil excavated from the photographic sites has been transported to
Thiokol's CAMU site at M-571 where they are undergoing treatment to remove any
hazardous characteristic. At the time of this report only the site at M-19A had not been
remediated to the corrective action levels of the plan. However, laboratory results of
verification samples taken following the most recent excavation are not yet available.
Thiokol has recently received an unsolicited proposal from a mining company in
westem Utah expressing an interest in the contaminated soils from the photographic
sites. The mine would reclaim the precious metals from the soil in a batch cyanide
leaching plant. This option is contingent upon Thiokol being successful in rendering the
soils nonhazardous so they can be managed as solid waste. A copy of the mining
company's proposal for the soils is included for the Division's review and
consideration.
Summaries of all findings;
Any available raw analytical data from all sampling activities during the reporting
period as well as data from the previous reporting period which was not available at the
time of reporting is included.
3. Summaries of all changes made in the RCRA Facility Investigation during the
reporting period.
Thiokol has identified three new solid waste management units to be included in the
Facility Investigation. A brief description of the unit's follows and an investigation
workplan are included.
SWMU No.: 669
Two historical "drying ponds" west of building M-13 received overflow wastewater
from the process sump at the north west end of the building. The overflow traveled via
a concrete ditch to the ponds where the water percolated and evaporated. Building M-
13 has been used as a grinding facility for ammonium perchlorate since its construction
in the early 60's. The ponds were removed many years ago but a portion of the
concrete trench is still visible. Other than the trench, no other visible physical evidence
oftheir location remains at the site.
SWMU No.: 670
Building M-16 also had two historical "drying ponds" believed to be similar in
constmction and function to those at Building M-13. Operations at M-16 include
several processes in the manufacturing of tactical motors. Again, these ponds were
removed many years ago with no remaining visible evidence of their location.
SWMU No.: 671
This unit is a drywell located east of building M-58. The building is currently used
only for storage of propellant materials and equipment, but has historically been used as
a propellant development oven. This drywell will be added to the investigation
workplan for other dry wells submitted previously, and the sampling strategy outlined in
that plan will be followed during assessment and sampling.
Investigation workplans for these newly identified SWMUs is included with this report.
4. Summaries of all contact with representatives of the local community, public
interest groups or State Gk)vernment during the reporting period;
Correspondence regarding RFI activities has been limited to the Division of Solid and
Hazardous Waste and the Division of Water Quality.
5. Summaries of all problems or potential problems encountered during the reporting
period.
There were no significant problems encountered during the reporting period.
6. Actions being taken to rectify problems;
Thiokol continues to review all available information and pursue all avenues to resolve
any uncertainty associated with the solid waste management units.
7. Changes in personnel during the reporting period.
The existing environmental staff will continue to conduct the sampling when possible.
Interstate Drilling of Midvale, Utah, is providing the equipment and operators to assist
Thiokol personnel in collecting environmental samples.
8. Projected work for the next reporting period.
Efforts for the next reporting period will focus on investigating additional solid waste
management units, completing and submitting the closure plan for the M-225 Burning
Area, completion of remediation of the sites in the CAMU, and report preparation for
these projects.
9. Copies of daily reports, inspection reports, laboratory and monitoring data.
Available analytical data from all sampling activities and any data from the previous
reporting period, which was not available at the time of reporting, is included.

The site of each pond will be divided into 5' x 5' grids. The intersection of the grids
will be numbered and sample locations chosen using a random number generator or
table. The actual sampling grids will be chosen the day of the sampling.
Two grids from each pond will be chosen and samples taken from 2, 5 and ten foot
depths. Duplicate and QA/QC samples will be collected at the frequency shown in the
following chart.
SAMPLE TYPE PROPOSED FREQUENCY
Duplicate 5% or 1 per site, which ever is greater
Rinse Field Blanks 5% or 1 per site, which ever is greater
Spikes 1% of the total RFI samples
6.0 BACKGROUND
Background samples have been collected in areas known or believed to be free of
contamination within the Manufacmring and Administration Area for use in comparing
concentrations. These background samples were collected at corresponding depths to
obtain samples in similar strata to those taken in the areas of concern.
Extensive soil sampling of the Thiokol facility has established a data base for naturally
occurring inorganic constituents. This data base consists of background samples used
in the closure of various RCRA facilities at Thiokol. The analytical results of the
background samples taken during Phase I sampling will be added to this data base to
provide site specific data. Analytical data obtained from investigation activities at this
site will be compared to this data base for determination of contamination above
background levels.

Dear Frank:
I( has comt to our attention tbat Thiokol has a quantity of silver contaminatBd soil dial has
been gathered and stabilized widi hiiit; and i:> ready to be landlllled We would like to
propose what may b$ an envjronmentaity preferable alternative. Clifton Mining has recenUy
c.oinpleted and placed in operation a small batch cyanide leaching plant (hat we believe would
be »utiiblt: for removing die silver from this soil. A brief description of the plant is
appended
We would propose screening the material at its present location to remove the relxtivef>'
uncontaminated rocks larger than 3/8", hauling the fine portion in our trucks to the plant at
Cold Hill, Utah, and processing it. Tbe fine din, with silver removed, could then be disposed
of with our other tailings, or retumed to 'Ihiokol for disposal.
We would need Thiokol to furnish a piece of equipment wirh operator to load the maienal
onto tite screen and/or trucks as needed Thiokol would also need to dispose of the rocks left
behind and pay any costs associated with returning the fine material to Thiokol, should that
be desired. Clil^on Mining would retain (he contained silver as payment.
We would expect that Thiokol representatives would visit the Clifton plant to evaluate its
suitability, and that Clifton representatives would visit the Thiokol site to xaice samples for
analysis before any agreement is finalized.
If you have any queshons or need further clarification, contact tne at (435) 753-115? or (801)
376'48?7 or Bill Moeiler or Keith Moeller at the numbers on the letterhead Thanks.

Gold Hill Leach Plant
Clifton Mining Co. has constructed a small plant at its Cactus Mill Site near Gold Hill, Utah.
It 18 a batch leach plant capable of processing about five to fifteen tons per day using sodium
cyanide or one of several altemate lixiviants to eMract gold and silver from ores m
concemrates
The plant occupies about 1800 .'iquare feet of a currently unused 5000 square foot building.
The equipment area is surrounded by a concrete relaining wail to provide secondary
containment of all hqutds u&ed.
The plant consists of two leach vessels, one 2400 gallons, thc other 3600 gallons, a slurry
pump, thickener, aad 4' x 9' honzontai belt filter. Soluhon from fte filter goes to a 6000
gallon prvg tank, through a Merrill-Crowe unil with a 3' x 3' plate & frame filter to a 5000
gallon barren tank.
Power is supplied by either of two diesel powered generators installed for other plants on site
Dry ground ore or concentrate is introduced to the leach vessels by front end loader. Hie
leached ore is double rinsed with clean water, treated with c.alaum hypochlorite to destroy
ony rooidual oyonido, ond vritr th« plant nrad nr filtar mlrii Tum furnii^«s tn •triilahl/' rin
site for melting of dore.
Process walei is recycled. Sak build up is dealt with by bleeding off small amounts of barren
solution as needed for evaporation and solids disposal
Cheiriicals used are sodium hydroxide, sodium cyanide, powdered zinc and small amounts of
a filter aid.

Data Reporting Qualifiers
U Indicates compound was analyzed for and was not detected, or the compound was detected but was
below the detection limit.
B Gas Chromatography and Mass Spectral Data Flag. This flag is used whien an analyte is found in
the blank as well as the sample
J Gas Chromatography and Mass Spectral Data Flag. Indicates an estimated value. This flag is used
either when estimating a concentration for tentatively identified compounds or when the data
indicated the presence of a compound that meets the identification criteria but the result is less than
the specified reporting limit (e.g. 3 J with a reporting limit of 10)
Det. Limit Method Detection Limit (approximately three times the signal noise level)
Rep. Limit Reporting Limit is normally the value of the lowest standard run with the analysis. The value
is approximately 5 to 10 times the Method Detection Limit
Dil. Factor Dilution Factor - The prepared sample was diluted by this factor because the sample was
too concentrated or due to other interferences in the sample matrix. Any dilution factor
causes an appropriate increase in the method detection limit and reporting limit
