WHITE MESA URANIUM MILL
SEMI-ANNUAL EFFLUENT REPORT, JANUARY THROUGH JUNE, 2012
1.0 INTRODUCTION
The White Mesa Mill (the "Mill") has established monitoring programs to evaluate
compliance with effluent limitations and to assess the potential for release of radioactive
material into the local environment. These monitoring programs were developed and
implemented at the time of Mill construction, operated with appropriate adaptation over
time, and are consistent with the Mill's State of Utah Radioactive Materials License No.
UT1900479 (the "License") and guidelines developed by the United States Nuclear
Regulatory Commission ("NRC") (NRC Regulatory Guide 4.14, Radiological Effluent
and Environmental Monitoring at Uranium Mills-Rev. 1, ML003739941), 1980).
Under these programs, the Mill monitors the following environmental media and
conditions:
a) Airborne particulate radionuclide concentrations obtained from the following
sampling stations:
• North, east and south of the Mill Site: BHV-1 and BHV-2 (north), BHV-5
(east), and BHV-4 (south). BHV-1 serves as a surrogate for the nearest
resident (BHV -1 is approximately 1.2 miles north of the Mill, but
approximately 0.4 miles closer to the Mill than the nearest resident);
• A background location distant to and west of the Mill (BHV-3), which
was monitored for airborne particulate up until November, 1995, at which
time background was established, but is no longer monitored for air
particulate; and
• A station specifically requested by the White Mesa Ute Community south
of the Mill Site (BVH-6);
a) External (direct) gamma radiation measured at air monitoring stations BHV-1,
BHV-2, BHV-3, BHV-4, BHV-5 and BHV-6;
b) Vegetation at three site periphery locations, for uptake of radiation;
c) Stack release rates from the Mill's air emissions sources;
d) Surface water at Cottonwood Creek and, when flowing, Westwater Creek, both
located west of the Mill;
e) Soil radionuclide activity obtained near the air particulate monitoring stations,
during the third quarter of each year;

N:\Required Reports\Semi Annual Effluent Reports\2012 Jan to June\Jan_to_June_2012_SAER_text.docx
f) Groundwater (up and down gradient) of the Mill facility; and1
g) Seeps and springs in the vicinity of the Mill.l
This semi-annual effluent report provides the results of the specific monitoring and
sampling activities that were undertaken during the subject reporting period.
2.0 ENVIRONMENTAL AIR PARTICULATE SAMPLING
2.1 Program Overview
The environmental airborne particulate monitoring program at the Mill utilizes four air
sampling stations. Four high-volume continuous air sampling stations (BHV-l, BHV-2,
BHV -4, and BHV -5) are required by the License. These sampling stations serve as
sentinels for airborne particulate which could potentially emanate from the Mill site. In
addition to its general site monitoring function, BHV -1 also serves as a conservative
surrogate for concentrations at the nearest resident, because it is located approximately
1.2 miles north of the Mill just south of the nearest resident but between the Mill and that
resident.
With regard to background monitoring, the Mill previously operated a continuous high-
volume air sampling station (BHV-3) which was located approximately 3.5 miles west of
the Mill site. With the approval of NRC, this station (BHV-3) was removed from the
active air monitoring program in November 1995. At that time, NRC determined that a
sufficient air monitoring data base had been compiled at BHV-3 to establish a
representative airborne radionuclide background for the Mill. It should be noted,
however, that while air sampling was discontinued at this location, gamma measurements
and soil sampling continue to be collected at BHV -3.
In addition to the environmental air sampling locations described above, an additional
station (BHV -6) was installed at the request of the White Mesa Ute Community. This
station began operation in July of 1999 and provides airborne particulate information in
the southerly direction between the Mill and the White Mesa Ute Community
2.2 Sampling Protocol and Analytical Results
Airborne particulate monitors are operated continuously at each of the high-volume air
sampling stations referenced above except BHV -3, as noted above. Particulate sample
collection filters are gathered by site technicians weekly in accordance with the Mill's
environmental air sampling procedures and are composited on a quarterly basis for
laboratory analyses. The collected filters are analyzed for Unat activity, Th-230 activity,
Ra-226 activity, and Pb-210 activity. Fugitive dust standards for the facility are limited
by the Mill's State of Utah Air Approval Order, which sets a 20% visual opacity
1 Groundwater sampling and seeps and springs sampling are reported separately pursuant to the Mill's State
of Utah Ground Water Discharge Permit No. UGW370004, and are not included with this report.

standard. The specific locations of the Mill's airborne particulate monitoring stations are
depicted on the figure entitled High Volume Air Monitoring Stations included as
Attachment A. Station BHV-3, which is no longer sampled for air particulate, is located
approximately 3.5 miles west of the Mill facility and is not indicated on that Figure.
The analytical results of radionuclide particulate sampling for each monitoring station
operated during this reporting period are provided in Attachment B under separate
sampling station attachment tabs (Tabs 1-6). Each Tab contains graphical illustrations of
the radionuclide concentrations in log-scale presentation format. The graphs display
reported data over time since the 1981 inception of the Mill's environmental air
particulate monitoring program. The actual analytical results (and associated QAlQC
information) reported by the laboratory for the reporting period are provided under
Attachment C. In addition to the analyses for radionuclides, particulate loading is
determined for each filter and compo sited as a quarterly mass-loading estimate for review
purposes only. Graphs showing particulate loading at each station for the first half of
2012 and the underlying data are included as Attachment D.
It should be noted that for BHV-6 the first 2 sampling periods of April 2012 have been
omitted from particulate loading on the graph in Attachment D. The timer on the
airborne particulate monitoring station at BHV -6 malfunctioned and the data are
considered invalid due to the inability to measure the time sampled. The timer was
replaced prior to the third sampling period and all other measurements are valid.
It should be noted that for graphical illustration purposes, values reported at zero, values
reported at less than the prescribed detection limit « 1 X 10-16 uCi/ml) and missing values
were plotted as 1 x 10-16 uCi/ml concentrations. Where other "less than" values were
indicated (i.e., where detection limits for the data varied from 1 x 10-16 uCi/ml), the
detection limit concentration was utilized for plotting the data point. This graphing
convention is not utilized to formulate station average information, nor is it intended as a
precedent for data treatment. Rather, the intent is to provide a conservative viewable
depiction of site airborne radionuclide information. This is considered to be a
conservative approach because the actual concentration below the detection limit cannot
be determined and, as a result, the plotted point will be at the same or a higher
concentration than the actual activity concentration of the collected sample.
2.3 General Observations
The results of environmental air monitoring for this semi-annual period indicate that for
all radionuclides at all monitoring stations airborne radionuclide particulate activity
concentrations were well below regulatory Effluent Concentration Limits ("ECL's") and
the Mill's ALARA goals, which are set at 25% of the ECLs.
It is noteworthy and expected that Pb-210 concentrations are elevated when compared to
the other parent radionuclide concentrations (i.e. U-nat, Th-230 and Ra-226). This
phenomenon is due to the well-established controlling effect experienced worldwide as a
3
N:\Required Reports\Serni Annual Effluent Reports\2012 Jan to June\Jan_to_June_2012_SAER_text.docx
result of the ubiquitous presence of radon in the earth's atmosphere. Accordingly,
elevated Pb-210 presence in disequilibrium with parent radionuclides measured here is
not associated with uranium milling operations. Rn-222 emanates as a decay-chain
progeny of the Ra-226 contained in the soil of the earth's crust and is dispersed generally
throughout the earth's atmosphere. The electrically charged short and long-lived decay
products of Rn-222 attach to ambient dust particles found naturally in the atmosphere and
are carried with the air. Pb-210 is the longest lived of these decay products and is the
decay product of the shorter-lived radon progeny. As such, it accumulates as an electrical
attachment on the natural ambient dust in the atmosphere and is generally measured at
elevated activity when compared to local decay-chain parent radionuclide activity,
regardless of uranium milling activity. At the Mill's BHV air monitoring stations, all
dust (ambient natural and mill derived) is collected by the sample filter. Because of the
natural elevation of Pb-210 accumulated as an attachment to the naturally occurring
ambient dust particles collected by the air sampling equipment, Pb-210 is commonly
elevated and in disequilibrium when compared to parent radionuclide activity, regardless
of the Mill's presence. By way of illustration, average ground-level concentrations have
been reported for selected States (NCRP Report 94, 1992) and are summarized in Table 1
below, demonstrating elevated Pb-210 activity where no uranium milling operations are
located nearby. Pb-210 activity concentrations can be expected to be even higher for
locations in the western U.S. where uranium ore bodies are commonly located. In April
1977, prior to Mill construction and Mill operations, air particulate Pb-210 was measured
at the Mill site to be 1.3E-14 uCi/ml (l3.0E-3 pCi/m3)2

2.4 Site Specific Sampling Data
The results of airborne particulate monitoring for the period (without background
subtraction) are provided by sampling station and radionuclide in Tables 2 through 5
below. Along with these data, the tables present comparative ECL's and the ECL
percentage measured at each of the monitoring stations sampled during the period. A
review of these data supports the conclusion that airborne particulate is well controlled at
the Mill. In all cases, the measured activity concentrations were well within the ECL, as
well as the Mill's ALARA goal (i.e. 25% of the ECL). Lower Limits of Detection

consistent with NRC Regulatory Guide 4.14 were maintained by the Mill's contract
analytical laboratory for this reporting period.
In fact, the data obtained since program inception in 1981 indicates that only one
individual quarterly measurement (Th-230 at BHV-5 for the 2nd Quarter of 1996) has
ever exceeded the ECL at the Mill. With regard to that particular single measurement,
while it is important to consider and evaluate an individual measurement exceeding the
ECL, for public dose estimation purposes, it is the average annual concentration that is of
primary significance. In that instance, the average annual concentration of Th-230 for
BHV -5 in 1996 was well below the ECL. Data obtained since program inception in 1981
also indicate that, with very few exceptions, the gross (background inclusive)
measurements do not exceed the site's ALAR A goal (i.e. only nine of the several
thousand total gross radionuclide determinations to date exceeded the Mill's self-imposed
25% ALARA goal).

2.5 Radon-222
Due to the unavailability of monitoring equipment to detect the revised 10 CFR Part 20
standard, and with the approval of NRC, Radon 222 monitoring at BHV stations was
discontinued in 1995. Instead, Denison demonstrates compliance with these limits and
the requirements of R313-15-301 by calculation, authorized by the NRC and as
contemplated by R313-15-302(2)(a). A copy of the Technical Evaluation Report
evidencing such approval was enclosed with correspondence to the Division of Radiation
Control ("DRC") on July 28, 2008.
This calculation is performed by use of the MILDOS code for estimating environmental
radiation doses for uranium recovery operations (Strenge and Bender 1981) and more
recently in 2003 by use of the updated MILDOS AREA code (Argonne 1998). The.
analysis under both the MILDOS and MILDOS AREA codes assumes the Mill to be
processing high grade Arizona Strip ores at full capacity, and calculates the
concentrations of radioactive dust and radon at individual receptor locations around the
Mill.
6
N:\Required Reports\Semi Annual Effluent Reports\2012 Jan to June\Jan_to_June_2012_SAER_text.docx
The MILDOS and MILDOS AREA codes calculate the combined Total Effective Dose
Equivalent ("TEDE") from all relevant pathways, including both air particulate and
radon, at a number of locations including the nearest residence (the individual likely to
receive the highest dose from the licensed operation), approximately 1.6 miles north of
the Mill. These calculations reveal projected doses to the individual likely to receive the
highest dose from the licensed operations to be well below the 1 00 mrem regulatory limit
in R313-15-301(1)(a) for all pathways, including air particulate and radon, and well
below the ALARA goal of 10 mrem/yr for air emissions excluding radon as set out in
R313-15-101(4). MILDOS AREA modeling was recently conducted in support of the
Mill's 2007 License Renewal Application, utilizing the MILDOS-AREA code (Version
2.20~), to estimate the dose commitments at various receptor locations for processing of
Colorado Plateau ore (0.25% U30 8 and 1.5% V 205) and Arizona Strip ore (0.637%
U30 8). The process rate was assumed to be at full capacity of 730,000 tons per year (an
average of 2,000 tons per day) with an average uranium recovery yield of 94%. That
modeling showed a TEDE of 2 mrem per year at the nearest resident (3 mrem per year at
the nearest potential residence, being the location of BHV -1 at the northern property
boundary of the Mill site), which included the dose from all radionuclide sources,
including radon. The modeled dose from radon itself was therefore a fraction of TEDE
and well within the regulatory limits.
3.0 EXTERNAL RADIATION (DIRECT GAMMA)
Gamma exposure rate estimates were measured for the reporting period utilizing passive
integrating devices, optically stimulated luminescence dosimeters ("OSLs"). These
dosimeters were located at each of the Mill's high-volume air sampling stations (BHV -1,
BHV-2, BHV-4, BHV-5 and BHV-6) and at the designated background monitoring
station (BHV-3). Measurements obtained from location BHV-3 have been designated as
background due to BHV-3's remoteness from the Mill site (i.e. BHV-3 is located
approximately 3.5 miles west of the Mill site). The results of the environmental OSL
measurements and semi-annual cumulative above-background data are provided in Table
6 below. In addition, measurement data obtained at these locations are graphically
presented at Attachment E to this report.

The results for this period indicate that above background measurements for stations
BVH-l, BVH-2, BVH-4, BVH-S and BHV-6 are within regulatory limits. BHV-l is at
the location of the nearest potential residence. The nearest actual residence is
approximately 0.4 miles north of BHV -1. The annual individual member of the public
limit is 100 mrem/yr for combined internal and external exposure.
4.0 VE(;ETATION SA~PLES
Vegetation samples are collected at three locations around the Mill property. The
sampling locations are: 1) northeast, 2) northwest and 3) southwest of the Mill facility.
The U.S. Nuclear Regulatory Commission ("NRC") Regulatory Guide 4.14 requires that
three samples be collected during the grazing season, without specifying exact months or
times during the season. During the 2012 grazing season, two sets of samples have been
collected, on April 11, 2012, and June 11, 2012. A third set of samples is planned for the
fall season. At the conclusion of the third quarter of 2011, three sets of samples have been
collected consistent with Regulatory Guide 4.14. The data from the fall season sampling
will be included in the July through December 2012 Semi-Annual Effluent Report
("SAER") which was submitted to the DRC on March 1,2013. Data from the April and
June sampling events are included in this report.
Graphical log-scale presentation of the vegetation sampling results, together with the
analytical results reported by the Mill's contract laboratory (including QAlQC
information) for this sampling period, are included at Attachment F of this report. The
2011 data results are within the variation of previous sampling episodes.
5.0 STACKSA~PLIN(;
Under Section S.O of Tab 1.4 of the Mill's Environmental Protection Manual, Revision:
DUSA-l, 2/07 (the "Environmental Protection Manual") gas stack samples are collected

The yellowcake dryer and yellowcake baghouse operated during the 1 st and 2nd quarters
of 2012. During the first half of 2012, the main Mill circuit did not operate. During the
second quarter of 2012, the main Mill circuit processed alternate feeds. Therefore the
grizzly baghouse was not in use either quarter, and no gas stack samples were collected
during the 2nd quarter of 2012.
The analytical results of stack sampling conducted for the 3rd and 4th quarters of 2011 and
for the 1 st and 2nd quarters of 2012, are provided in Table 8 below, indicating the uCi/cc
concentration in the stack emissions and the stack's radionuc1ide release rate (uCi/sec) for
V-Nat, Th-230, Ra-226 and Pb-210 at each of the stacks sampled. The actual analytical
results reported by the laboratory for the 1 st and 2nd quarters of 2012 are provided in
Attachment G to this report.
It is also important to note that stack effluent concentrations are not comparable to
environmental air sampling station ECL's for regulatory compliance purposes. The ECL
is a limit that applies to the receptor locations and is not applicable to effluents from mill
processes on the Mill site. These stack release data are more appropriately utilized for
dose modeling purposes, and dose modeling is not computed for semi -annual reporting
purposes.

6.0 SURFACE WATER MONITORING
Under the License, Part 11.2 B surface water samples are required to be obtained
annually from Westwater Canyon and semi-annually from Cottonwood Creek. Sediment
samples from Westwater Canyon are taken in place of the Westwater Canyon surface
water sample in the event that surface water is not available for sampling. Westwater
Canyon surface water was not sampled in the first or second quarter 2012 because no
water was present during this reporting period. Attempts to collect a surface water sample
from Westwater Canyon will continue through the next reporting period. If no surface
water is available, a sediment sample will be collected as required.
The Mill's Environmental Protection Manual, requires that Cottonwood Creek be
sampled for TDS and total suspended solids TSS quarterly, and the License, Part 11.2 B
requires that Cottonwood Creek be sampled for dissolved and suspended radionuclides
including Gross Alpha, Unat, Ra-226, Th-230 semi-annually. In accordance with these
requirements, Cottonwood Creek was sampled for TDS and TSS durin§ the 1st quarter.
Surface water was not collected from Cottonwood Creek during the 2n quarter of 2012
because there was no surface water present during the quarter.
The field data sheets for the surface water sampling events, along with graphs showing
historic results are included as Attachment H. The results of this sampling indicate that
surface water results remain low and within the range of typical background.
7.0 SOIL SAMPLING
Under Tab 4.1 of the Mill's Environmental Protection Manual, surface soils are required
to be sampled at the Mill's air monitoring stations (BHV-1, BHV-2, BHV-3, BHV-4,
BHV -5 and BHV -6) once per year during August or as soon as possible thereafter, but no
later than -September 30 of each year. In accordance with the Mill's Environmental
Protection Manual, surface soils will be collected during the third quarter 2012 and will
be discussed in the July through December 2012 report.
8.0 METEOROLOGICAL MONITORING
As in prior reporting periods, an independent contractor has prepared the White Mesa
Mill Semi-annual Meteorological Monitoring Report for the period of January through
June, 2012. This information is retained at the Mill site for agency review.

Sample Delivery Group: C12040316 CASE NAR RATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for
seven individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria
for PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize
its branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

CLIENT: Denison Mines USA Corp
Project: 2nd Quarter Air 2012 Report Date: 08/10/12
Sample Delivery Group: C12070341 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the ch illing process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewe9 as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for
seven individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria
for PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize
its branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the

Standard Reporting Procedures
Lab measurement of analytes considered field parameters that require analysis within 15 minutes of sampling such as pH, Dissolved Oxygen and Residual
Chlorine, are qualified as being analyzed outside of recommended holding time.
Solid/soil samples are reported on a wet weight basis (as received) unless specifically indicated. If moisture corrected, data units are typically noted as -dry.
For agricultural and mining soil parameters/characteristics, all samples are dried and ground prior to sample analysis.

BRANCH LABORATORY SUBCONTRACT ANALYSIS
Report Date: 06/05/12
CASE NARRATIVE
Tests associated with analyst identified as ELI-CS were subcontracted to Energy Laboratories, 415 Graham Rd., College
Station, TX, EPA Number TX01520
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

Project: Late Spring Vegetation 2012 Report Date: 08/09/12
Sample Delivery Group: C12060622 CASE NARRATIVE
PB21 0 ANALYSIS
USNRC Regulatory Guide 4.14 provides guidance on Minimum Detectable Concentrations (MDC) that should be achieved
in samples for this radionuclide. The sample-specific MDC for this sample could not be achieved due to significant matrix
interferences, restricting the volume of sample to be used in the analysis. Please consult with your local regulatory agency
prior to using these results for compliance purposes.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for
seven individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria
for PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize
its branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

Standard Reporting Procedures
Lab measurement of analytes considered field parameters that require analysis within 15 minutes of sampling such as pH, Dissolved Oxygen and Residual
Chlorine, are qualified as being analyzed outside of recommended holding time.
Solid/soil samples are reported on a wet weight basis (as received) unless specifically indicated. If moisture corrected, data units are typically noted as -dry.
For agricultural and mining soil parameters/characteristics, all samples are dried and ground prior to sample analysis.

INTRODUCTION
Test Pur[!ose
This test project was conducted to determine the total radiol1uclide emissions frOln the North
Yellow Cake Scrubber and the Yellow Cake Dryer Baghouse exhausts in terms of Curies per dry
standard cubic foot (Ci/dsct).
These tests were for U-Nat only.
Test Location and Type of Process
Denison Mines (USA) Corporation is located about 5 miles south of Blanding, Utah. Uranium
ore is processed into yellow cake, which is shipped to other facilities for additional processing.
There are two yellow cake dryers with individual scrubbers. Both dryer enclosures discharge into
the Yellc)\,v Cake Dryer Baghouse. 'fhe packaging enclosure also discharges into the Yellow
Cake Dryer Baghouse. The North Yellow Cake (NYC) dryer was the only operating dryer at the
time of the test. The South Yellow Cake dryer is currently not operational. The Grizzly
Baghouse serves as the main dust control device for the raw ore unloading and conveying to the
processing building.
Stack schematics are shown as Figures 1 and 2 in Appendix D.
Test Dates
One test run was completed on the NYC Scrubber February 28, 2012 and one run on February
29th .
One run was completed on the Yellow Cake Dryer Baghouse February 29. 2012.
Pollutants Tested and Metbods Applied
The tests were a determination of radionuclide emissions in accordance with EPA Method 5/114.
Test run filters and front wash residues were sent to Test America located in Richland,
Washington for radionuclide analysis.

SAMPLING AND ANALYSIS PROCEDURES
SamplingRQ[t Location
The inside diameter of the NOlih Yellow Cake Scrubber stack is 18.0 inches. The two, f-our-inch
diameter smnple pOli are located 6.3 diameters (9.5 feet) downstream from the last disturbance
and 6.3 diameters (9.5 feet) upstream from the next disturbance. Figure 1 in Appendix 0 is a
schenlatic of the stacie
The inside diameter of the Yellow Cake Dryer Baghouse stack is 16.0 inches. The two, four-inch
diameter sample ports are located 28.38 diameters (454 inches) downstream from the last
disturbance and 3.56 diameters (57 inches) upstream from the next disturbance.' The sample port
locations are depicted in Figure 2 in Appendix D.
Sanipling Point Location.
Table HI shovvs the distance of each san1pling point from the inside wall according to EPA
Method 1. Each point is ll1arked and identifIed with a wrapping of glass tape and numbered.
These points are determined by 111easuring the distance from the inside wall.

SanapUng Train Descaoiption
To determine the actual emission rates for this stack, 40 CFR 60, Appendix A, ivlethods 1-5/1 ] 4
were followed.

All sampling trains were made of inert materials, (Te-tlon, stainless steel and glass) to prevent
interference of the smnpled gas and particulate. The stack analyzers used to conduct Methods 1-
5/] 14 are constructed to meet the specifications outlined in the CFR. The temperature sensors are
K-type thennocouples. Heater, vacuum and pitot line connections have been designed to be
interchangeable with all units used by the tester. A 316 stainiess steel probe liner was llsed for the
tests. Figure 4 in Appendix E is a sketch of the I\1ethods 51114 sampling train.
Sample boxes were prepared for testing by following the prescribed procedures oUllined in
Methods 5/114.
Sampling and Analvtical Procedures
All sampling and analytical test procedures were as specified in 40 CFR 60, Appendix A,
Methods 5/114.
Quality Assurance
All equipment setup, sampling procedures, sample recovery and equipll1ent calibrations were
carried out according to the procedures specified in 40 CFR 60 and the Quality Assurance

Alpha Spectroscopy
Uraniurn-234, 235, 238
Samples 5866, 5867 R I NYC and 5868, 5869 R2 NYC initially failed due to smeared spectra. The re-
analysis is within acceptance criteria. The achieved MDA of the batch exceeds the detection limit from
reduced aliquot sizes taken due to historical process knowledge. The sample activity exceeds the MDA
and detection limit for three of the four samples. The batch blank activity also exceeds detection limit;
however, the blank results are significantly lower than sample results. Data is accepted. Except as noted,
the LCS, batch blank, sample and sample duplicate results are within acceptance limits.
[ certify that this Certificate of Analysis is in compliance with the SOW and/or NELAC, both technically
and for completeness, for other than the conditions detailed above. The Laboratory Manager or a
designee~ as verified by the following signature has authorized release of the data contained in this hard
copy data package.

Uncertainty Estimation
TestAmerica Richland has adopted the internationally accepted approach to estimating
uncertainties d(~scribed in -'NIST Technical Note 1297, 1994 Edition". The approach, "Law ofPropagatioll
of Errors". involves the id(:~ntificati()n of all variables in an analytical method which are used to derive a
result. These variables are related to the analytical result (R) by some functional relationship, R = constants
* t1x,y,z, ... ). The components (x.YJ) are evaluated to determine their contribution to the overall method
uncertainty. The individual component unceltainties (ut) are then combined using a statistical model that
provides the most probable overall uncertainty value. All component uncertainties are categorized as type
A. evaluated by statistical methods. or type t3. evaluated by other means. Uncertainties not included in the
components, such as sampJe homogeneity, are combined with the component uncertainty as the square root
oCthe sum-of-the-squares oCthe individual uncertainties. The uncertainty associated with the derived result
is the combined uncertainty (u,,) multiplied by the coverage factor (1,2, or 3).
When three or more sample replicates are llsed to derive the analytical result, the type A
uncertainty is the st.andard deviation of the mean value (Sf? n), where S is the standard deviation of tile
derived results. The type B uncertainties are all other randorn or non-random components that arc not
included in the standard deviation.

INTRODUCTION
Test Purpose
This test project was conducted to detern1ine the total radionuclide emissions fi'om the North
Yellow Cake Scrubber and Yellow Cake Dryer Baghouse exhausts in terms of Curies per dry
standard cubic foot (Ci/dscf). The Grizzly Baghouse was not tested the second quarter as it was
not operational.
These tests were for lJ-234~ -235, -238, Th-228~ -230, -232, Ra-226, and Pb-21 ° on the North
Yellow Cake Scrubber and Yellow Cake Dryer Baghouse.
Test Location and Type of Process
Denison Mines (USA) Corporation is located about 5 miles south of Blanding, Utah. Uranium
ore is processed into yellow cake, which is shipped to other facilities for additional processing.
There are two yellow cake dryers with individual scnlbbers. Both dryer enclosures discharge into
the Yellow Cake Dryer Baghouse. The Packaging enclosure also discharges into the Yellow
Cake Dryer Baghouse. The North Yellow Cake (NYC) dryer was the only operating dryer at t.he
time of the test. The South Yellow Cake Dryer is cun-ently not operational. Stack schematics are
shown as Figures 1 though 2 in Appendix D.
Test Dates
All testing was c0111pleted May 15-16,2012. Specific dates and run tilnes are found on the
individual field test run sheets.
Pollutants Tested and Methods Applied
The tests were a determination of radio nuclide emissions in accordance with EPA Method 5/114.
Test rill1 filters and front wash residues were sent to Test Arnerica located in Rjchland~
\Vashington for radiol1uclide analysis.

SAMPLING AND ANALYSIS PROCEDURES
SamJ2ling Port Location
The inside diameter of the North Yellow Cake Scrubber stack is 18.0 inches. The two, four-inch
dian1eter sample port are located 6.3 diameters (9.5 feet) downstream from the last disturbance
and 6.3 diameters (9.5 feet) upstream from the next disturbance. Figure I in Appendix 0 is a
sche111atic of the stack.
The inside diameter of the Yellow Cake Dryer Baghouse stack is 16.0 inches. The two, four-inch
dianleter smnple ports are located 28.38 diameters (454 inches) downstream from the last
disturbance and 3.56 dianleters (57 inches) upstream fi-om the next disturbance. The sample port
locations are depicted in Figure 2 in Appendix D.
Sampling Point Location
Table III shows the distance of each sampling point fronl the inside waLl according to EPA
T\1ethod 1. Each point is lnarked and identified with a wrapping of glass tape and numbered .
T'hese points are detef111ined by measuring the distance fro111 the inside wall.

S~unpliug Train Description
To determine the actual emission rates for this stack, 40 CPR 60, Appendix A, iVlethods 1-51114
were followed.
All sampling trains were nlade of inert Inaterials, (Teflon, stainless steel and glass) to prevent
interference of the sampled gas and patiiculate.
The stack analyzers used to conduct Methods 1-5/114 are constructed to meet the specifications
outlined in the CFR. The temperature sensors are K -type thermocouples. Heater, vacuum and
pitot line connections have been designed to be interchangeable with all units used by the tester.
A 316 stainless steel probe liner was used for the tests. Figure 4 in Appendix E is a sketch of the
Methods 5/114 sampling train.
Sample boxes were prepared for testing by following the prescribed procedures outlined in
Methods 51114.
Sampling and Analytical Procedure~
All sampling and analytical test procedures were as specified in 40 CFR 60, Appendix A,
Methods 5/114.
Quality Assurance
All equipment set-up, san1pling procedures, sample recovery and equipment calibrations were
can-ied out according to the procedures specified in 40 CFR 60 and the Quality Assurance
Handbook/hI" Air Pollution j\.1easurernent Systems.

IV. Quality Control
The analytical result for each analysis performed includes a minimum of one laboratory control sample
(LCS), and one reagent blank sample analysis. Any exceptions have been noted in the "Cotnillents"
section.
V. Comments
Alpha SpectroscollY
Thorium-228. 230. 232
The blank activity ofTh-230 exceeds the detection Hmit~ however, it is less than the activity in the
samples. The achieved MDA of the samples exceeds the detection limit due to insufficient saITlple
volume. However, in most cases, the activity oftlle samples exceeds the MDA and detection limit. The
data is reported. Except as noted, the LCS, batch blank and sample results are within acceptance limits.
Uranium-234. 235. 238
The achieved MDA of the batch exceeds the detection limit from reduced aliquot sizes taken due to
historical process knowledge. The sample activity exceeds the MDA and detection limit for the sarnples.
Data is accepted. Except as noted, the LCS, batch blank, sample and sample duplicate results are within
acceptance limits.
Gamma Spectj'oscoPY
Pb-210
The achieved MDA of the samples exceeds the detection limit due insufficient sample volume. The LCS
recovery yield is just above acceptance limits. A recount did not improve the recovery. There is no
sample volume remaining for fe-analysis. Data is repolied. Except as noted, the LCS, batch blank,
sample and sample duplicate results are within acceptance limits.
Alpha Scintillation
Radi llm-226
The achieved MDA of the samples exceeds the detection limit due insufficient sample volume. Sample
activity exceeds MDA and detection limit for all of the samples. Data is accepted. Except as noted, the
LCS. batch blank and sample results are within acceptance limits.
I certify that this Certificate of Analysis is in compl iance with the SOW and/or N ELAC, both technically
and for completeness, for other than the conditions detailed above. The Laboratory Manager or a
designee, as veritied by the following signature has authorized release of the data contained in this hard

Uncertainty Estimation
TcstAmerica Richland has adopted the internationally accepted approach to estimating
uncertainties described in «NISTTcchnical Note 1297, 1994 Edition". The approach, "Law of Propagation
of Errors", involves the identil'ication ofal! variables in an analytical method which are llsed to derive a
resLlIt. These variables are related to the analytical result (R) by some functional relationship, R =-= constants
* f{x,y,z, ... ). The components (x,y.z) are evaluated to detennine their contribution to the overall rncthod
ullcel1ainty. The individual component uncertainties (Ui) are then combined using a statistical modellhat
provides the most probable overall uncertainty value. All component uncertainties are categorized as type
A, evaluated by statisticaJ methods, or type B, evaluated by other means. Uncertainties not included in the
components, such as sample homogeneity, are combined with the component uncertainty as the square I"()ot .
of the sum-of .. the-squares of the individual uncertainties. 'fhc uncertainty associated with the derived result
is the combined uncertainty (ue) multiplied by the coverage factor (1 ,2, or 3).
When three or more sample replicates are used to derive the analytical result, the type A
uncertainty is the standard deviation of the mean value (Sl?n), where S is the standard deviation of the
derived results. The type B uncertainties are al l other random or non-random components that are not
included in the standard deviation.
The derivatlon of the general 11 Law of Propagation of Errors" equations and specil1c example are
available on

Project: 1 st Quarter Surface Water 2012 Report Date: 04/02/12
Sample Delivery Group: C12030626 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has
begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.
