Investigation completed
Perchlorate in Soil Treatment - Voluntary Corrective Measure
A new SWMU was identified in February 2005 at building M-721 and designated
as #677 This is an Ammonium Perchlorate (AP) reclamation facility This
SWMU was the result of a release of ammonium perchlorate in November 2004
Approximately 25 gallons of a high percent solution of perchlorate were relea.sed
when excess foaming in a process tank caused a vent to overflow This flow went
onto a concrete pad and then to the sunounding soil Soil was removed from the
site in an attempt to get to reach Region Nine PRG residential levels in soil
(8ppm) After repeated excavations, it was determined that levels of perchlorate
were still high, but to continue digging the high areas would effect the structural
integrity of the building pad and steam line Depths of 4 5 feet were reached in
areas of higher concentrations and approximately 54 yd" of soil were removed
The level of perchlorate in the final excavation ranged from 1680 ppm to 6150
ppm Another remediation or removal process will need to be implemented in the
future
Approximately 70 cubic yards of soil were removed from this site and another
spill site at M-705 as part of the investigation This soil was staged at E-501
storage area with a plastic cover to minimize storm water runoff
ATK Thiokol investigated various methods of treating and disposing of the
perchlorate contaminated soils and determined to test bio-remediation In June
2005 a plan was submitted lo the Utah DSHW detailing anaerobic compositing of
the soil as a means of treating the perchlorate contamination A copy of the Plan
entitled. Treatability Study vvoik Plan lo Evaluate Ex-situe Remediation of
Perchlorate Contaminated Soil, is attached as a reference The DSWH
subsequently gave comments and approval to cany out the pilot test in August
2005 This pilot test is now underway and results will be reported in a subsequent

WORK PLAN FOR A CORREECTIVE-MEASURE PILOT TEST
TO EVALUATE EX-SITU REMEDIATION OF
PERCHLORATE-CONTAMINATED SOIL
CHAPTER 1
INTRODUCTION
ATK Thiokol Inc ("ATK") and its predecessors have operated a rocket propulsion
system manufacturing and testing facility since 1957 at Promontory, Utah, located
approximately 70 miles northwest of Salt Lake City, Utah During the first 20 to 30 years of
facility operation, wastes such as spent solvents and energetics were disposed of pnmarily in
unlined impoundments or directly to the ground surface These disposal practices resulted in
contamination of soil and groundwater at vanous locations within and adjacent to the plant
boundaries
Extensive investigations of soil and groundwater contamination at the facility have
occurred since 1985 Interim remedial measures have been implemented since that time to
reduce the impacts of past operations on groundwater quality Additional evaluations are
currently underway or planned to further address groundwater-quality concerns in the area
To assist in future decisions regarding source soil remediation, ATK proposes to
conduct a pilot test to evaluate ex-situ anaerobic bioremediation of perchlorate-contaminated
soil The purpose of this document is to present a work plan for the proposed test Although
the soil IS neither a CERCLA nor a RCRA waste, this work plan is organized in general
accordance with treatability study guidelines outlined by the U S Environmentai Protection
Agency (1993) for CERCLA sites, thereby allowing a more thorough review of the work plan

TECHNOLOGY DESCRIPTION
Significant research has been conducted since the late 1990s on the ability of anaerobic
bacteria to degrade perchlorate (see, for example, reviews wntten by Xu et al [2003] and
Coates and Achenbach [2004]) This work has resulted in the isolation of several perchlorate-
reducing bactena, all of which are facultative anaerobes or microaerophiles As a group, these
bacteria appear to be ubiquitous and phylogeneticaiiy diverse
Under anaerobic conditions, perchlorate serves as an electron acceptor dunng the
oxidation of organic material and is reduced according to the following pathway
perchlorate -> chlorate -> chlonte -> chlonde
The rate-limiting step is the reduction of perchlorate to chlorate Hence, the reduction of
chlorate to chlonte and eventually chlonde and oxygen is relatively rapid, thereby avoiding
accumulation of chlonte as a toxic byproduct of biodegradation Stoichiometncally, this reaction
can be written as
CIO4" + 8H^ + e" -> cr + 4H2
indicating that four moles of H2 are required to reduce one mole of perchlorate
Anaerobic conditions can be achieved through the addition of appropnate organic
substrates to stimulate microbial growth As these substrates are biodegraded, oxygen and
other natural electron acceptors (e g , nitrate, manganese, iron, etc ) are depleted, thereby
promoting anaerobic degradation of contaminants Typical substrates used to promote
anaerobic biodegradation include alcohols (e g , ethanol and methanol), low molecular weight
fatty acids (e g , lactate), carbohydrates (e g , molasses, high-fructose corn syrup, and cheese
whey), vegetable oils, and agncultural wastes (e g , compost and manure)

CHAPTER 3
WORK PLAN
3.1 PILOT TEST GOALS
The objective of this pilot test is to evaluate the efficacy of an organic substrate on
promoting anaerobic biodegradation of perchlorate in soil at the ATK Promontory facility The
treatment goal for the study is a perchlorate concentration of 55 mg/kg, the preliminary
remediation goal based on soil ingestion by a child under a residential land-use scenano (see
Appendix A) The reference dose used for this determination was 0 0007 mg/kg-day as recently
recommended by the Committee to Assess the Health Implications of Perchlorate Ingestion
(2005)
As indicated in Section 3 7, soil that meets the treatment goal will be removed and
disposed of at the Promontory M-336A sanitary landfill following completion of the pilot test
Data presented in Appendix B indicate that there is no significant potential for migration of
perchlorate from the treated soil in the landflll to groundwater Hence, no adjustment of the
treatment goal is needed to account for this pathway
3.2 PILOT TEST DESIGN
Most expenence with perchlorate degradation has focused on remediation of
contaminated groundwater (Roote, 2001) However, recent efforts have also extended to
remediation of vadose-zone soils, either in-situ or ex-situ (Cox et al , 2004) As in groundwater,
soil remediation is achieved by providing an organic growth substrate in sufficient quantities to
promote anaerobic conditions that allow bactena to reduce perchlorate to innocuous
byproducts
The perchlorate-impacted soil to be used in the pilot test (approximately 60 to 70 yd^)
was previously excavated from a spill that occurred at Building M-721 (the perchlorate
reclamation facility) The area of this spill has been designated as Solid Waste Management
EarthFax Engineering, Inc
ATK Thiokol Inc Perchlorate Soil Pilot Test Work Plan
Promontory, Utah September 28, 2005
Unit 677 Following excavation, the soil was placed on the asphalt surface adjacent to the E-
501C material storage area Analyses of three samples of this soil indicated perchlorate
concentrations ranging from 150 to 906 mg/kg (see Appendix C)
Field pilot tests are normally conducted following the performance of laboratory bench-
scale investigations However, given the relatively small quantity of soil that has been
excavated, ATK has chosen to focus this investigation directly on field application This pilot
test will be conducted under the roof of the E-501 C material storage area, an open-sided
structure with a footprint of approximately 36 feet by 50 feet Accounting for support beams in
the interior of the structure, three biopiles can be constructed at E-501 C, each covenng an area
of about 15 feet by 30 feet
Horse or cow manure will be used as the organic substrate for this study, depending on
availability at the time of the test Typical ratios of manure addition used previously by others to
promote ex-situ anaerobic biodegradation of vanous contaminants in soil range from 10% to
90% of the final biopile volume (see Beul et al [2003], Weeks et al [2003], U S Environmentai
Protection Agency [1998], Inglis [2000], and Roote [2001]) Ratios of 20%, 40%, and 60%
manure (by volume) will be used for this study At these ratios, it is estimated that all of the
stockpiled soil will be treated in the three biopiles
Manure will be mixed with the soil at the appropnate ratios on the adjacent asphalt
surface using a front-end loader Volumes will be measured with the front-end loader bucket
(e g , at the 40% mixing ratio, three bucketfuls of soil will be mixed with two bucketfuls of
manure) Water will be sprayed during mixing to nearly saturate the soil (thereby reducing the
initial oxygen content of the soil to the degree practical) The soil comprising each biopile will be
sampled during mixing, as outlined in Section 3 4, to provide an indication of initial conditions
One layer of 10-mil polyethylene sheeting will be placed on the concrete floor of the E-
501C matenal storage area beneath each biopile Once the soil and substrate are mixed, the
mixture will be placed on the sheeting, taking care not to drive on top of the sheeting
Temperature probes will be placed in the piles and attached to an on-site data logger to monitor
EarthFax Engineering, Inc

pile conditions Four-inch diameter perforated PVC pipe will be laid along the top of each pile,
with an unperforated nser connecting into the perforated pipe and extending at least 8 feet
above the top of the biopile This piping will serve to vent gases from the piles once anaerobic
conditions are achieved Each biopile will then be covered with 10-mil polyethylene sheeting
and the top and bottom layers of sheeting will be glued together to create an airtight pile A
polyethylene boot will be used to seal the ventilation nser to the top cover
3.3 EQUIPMENT AND MATERIALS
The pnmary equipment to be used in this pilot test will be a front-end loader Water from
the Promontory potable or firewater system will be used to moisten the soil dunng mixing A
data logger, with temperature probes, will be located on site to monitor pile conditions Other
matenals to be used dunng biopile construction include manure, polyethylene sheeting, and
PVC piping, all of which will be purchased off site It is not anticipate that any other significant
equipment or matenals will be used dunng the test
3.4 SAMPLING AND ANALYSIS
Samples of the soil will be collected during initial mixing and penodically throughout the
duration of the pilot test Table 1 lists the anticipated sampling frequency and analytical
parameters All samples will be analyzed for perchlorate and chlorate (the contaminant of
concern and its most persistent degradation byproduct) as well as pH (an indicator, during
treatment, of the generation of organic acids from the anaerobic fermentation process)
Selected samples collected dunng the study will also be analyzed for nitrate and sulfate (natural
electron acceptors) as well as iron, manganese, and selenium (natural electron acceptors as
well as trace elements important for the growth of perchlorate-reducing bacteria [Xu et al,
2003]) Initial and final samples collected from the biopiles will be analyzed for the metals
covered by EPA Method 601 OB, following extraction by the Synthetic Precipitation Leaching
Procedure (EPA Method 1312), to assist in determining whether the remediation process affects
metals mobility
EarthFax Engineering, Inc
ATK Thiokol Inc Perchlorate Soil Pilot Test Work Plan
Promontory, Utah September 28, 2005
Samples submitted for analyses will be composites of at least four subsamples collected
from each biopile The initial subsamples will be collected using a stainless steel spoon at
arbitrary locations dunng mixing of the soil following addition of the substrate Subsamples from
the constructed biopiles will be collected using a stainless steel bucket auger from two depths at
each of two locations selected randomly within the biopiles A slit will be made in the cover the
allow entry of the auger After sampling, the cover will be re-sealed with tape or another
appropnate method
Subsamples from each biopile will be placed in a polyethylene bag or stainless steel
bowl and thoroughly mixed A composite sample will then be collected and placed in a new
glass jar The sample will be kept on ice pnor to delivery to the analytical laboratory All
sampling equipment will be decontaminated between piles using a Liquinox wash and a
distilled-water rinse Decontamination water will be containenzed in a bucket and disposed of at
the Promontory wastewater treatment plant Samples will be analyzed according to the
methods indicated in Table 2 by the Thiokol Environmentai Laboratory located at Promontory
To account for dilution due to substrate presence, an initial set of samples will also be
collected from the soil prior to mixing with the manure A portion of the soil to be incorporated
into each biopile will be homogenized through repeated overturning by the front-end loader pnor
to combining with the manure A subsample will be collected from this soil, the appropnate
volume of manure will be mixed with the soil, and an additional subsample will be collected
The subsamples will be collected and composited as outiined above, with one composite for
each biopile Each pre- and post-mix composite will be analyzed for perchlorate in accordance
with Table 2 The resulting data will be evaluated to determine the degree to which dilution has
affected the initial perchlorate concentration
3.5 DATA MANAGEMENT, ANALYSIS, AND INTERPRETATION
All data collected dunng this pilot test will be maintained in both electronic and hard-
copy formats All field notes will be kept in log books and will detail methods, quantities, and
site observations dunng biopile construction, operation, and sampling
EarthFax Engineering, Inc
ATK Thiokol Inc Perchlorate Soil Pilot Test Work Plan
Promontory, Utah September 28, 2005
Perchlorate data collected from the vanous piles will be evaluated graphically and
statistically to determine the extent of degradation and variations between treatments Final
decisions regarding statistical analyses will be made once the data are obtained Other
information (i e , temperature data, electron-acceptor concentrations, general site observations,
etc ) will be evaluated as appropnate to help draw conclusions regarding the study
3.6 HEALTH AND SAFETY
Standard health and safety procedures appropriate for the site will be followed As a
minimum, these will include the use of Level D personal protective measures (i e , steel-toed
boots, hard hats, etc ) for all site personnel dunng biopile construction and sampling
Furthermore, site personnel involved in this pilot test will have received training in accordance
with OSHA HAZWOPER requirements Special care will be taken around moving equipment to
ensure personnel safety
3.7 RESIDUALS MANAGEMENT
The soil and manure will be mixed on the asphalt surface adjacent to the soil stockpile,
thereby minimizing the spread of contamination The biopiles will be lined and covered The
quantity of water added to the soil dunng mixing will be sufficient to result in a visibly "wet"
condition without significant free water The covered area where the biopiles will be constructed
consists of a concrete floor surrounded by concrete berms Hence, contaminated water (if any)
will not leave the site (either from runoff or leaching) during performance of the pilot test Since
water will be added to the soil as it is mixed, dust will not be generated dunng construction of
the biopiles
Soil removed from the piles dunng sampling will either be retained for off-site analyses
or will be placed back into the auger hole from which it was removed The amount of water
required to decontaminate the sampling equipment between biopiles will be kept to a minimum
(i e , 2 to 3 gallons per sampling event) Rinse and wash water used in decontamination will be
EarthFax Engineering, Inc
ATK Thiokol Inc Perchlorate Soil Pilot Test Work Plan
Promontory, Utah September 28, 2005
containerized and disposed of at the Promontory wastewater treatment plant No other
wastewater will be generated dunng the pilot test
Treatment of a biopile will continue until perchlorate concentrations in composite
samples collected on at least two occasions from the biopile are less than the treatment goal,
accounting for dilution as outlined in Section 3 4 After the treatment goal in a biopile has been
reached, the soil will be removed and disposed of at the Promontory M-336A sanitary landflll
Soil that does not meet the treatment goal will be re-treated as necessary until the goal is met,
accounting for dilution if necessary based on the additional material added When a biopile is
disassembled, all waste materials (i e , cover, ventilation piping, and liner) will be disposed of at
the M-336A sanitary landfill
3.8 REPORTS
A report descnbing the implementation and results of the pilot test will be prepared at the
end of the project
3.9 SCHEDULE
Field work associated with the pilot test will begin as soon as possible after approval of
the work plan It is anticipated that biopile construction will be completed within one week The
duration of the test will be a function of the rate of degradation

EVALUATION OF SOIL TO GROUNDWATER PATHWAY
81. EVALUATION
To evaluate the potential for perchlorate to migrate from soil disposed of in the M-336A
landflll to groundwater, a water balance evaluation was conducted in accordance with methods
outlined by Thornthwaite and Mather (1957), as modified by the U S Environmentai Protection
Agency (1975) Results of this evaluation, presented in Table B1, indicate that no significant
potential exists for water to percolate from the M-336A site below a depth of 5 feet under normal
conditions As a point of reference, the depth to groundwater at the landfill is approximately 120
to 130 feet The lack of deep percolation predicted by this evaluation is due to the moisture
deficit created by the high annual potential evapotranspiration (24 3 inches) relative to the
annual precipitation (14 3 inches)
