WHITE MESA URANIUM MILL
SEMI-ANNUAL EFFLUENT REPORT, JULY THROUGH DECEMBER, 2010
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-l and BHV-2 (north), BHV-5
(east), and BHV-4 (south). BHV-l serves as a surrogate for the nearest
resident (BHV-l 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
ofthe Mill Site (BVH-6);
a) External (direct) gamma radiation measured at air monitoring stations BHV-l,
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;

f) Groundwater (up and down gradient) of the Mill facility; and l
g) Seeps and springs in the vicinity of the Mill. I
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 radionuc1ide 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. 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
I 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.

Utah Air Approval Order, which sets a 20% visual opacity 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 January through June, 2011 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 QAJQC information) reported by the laboratory are provided
under Attachment C. In addition to the analyses for radionuclides, particulate loading is
determined for each filter and composited as a quarterly mass-loading estimate for review
purposes only. Graphs showing particulate loading at each station for the second half of
2010 and the underlying data are included as Attachment D.
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-21O 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
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
3
N:\Required Reports\Semi Annual Effluent Reports\2011 Jan to
June\J an_to_Jun_20 II_Semi_annuaLEffluenCReport_Main_text.docx
products of Rn-222 attach to ambient dust particles found naturally in the atmosphere and
are carried with the air. Ph-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-21O 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-21O activity where no uranium milling operations are
located nearby. Pb-210 activity concentrations can be expected to he 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 (13.0E-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). It should also be noted that the
analytical laboratory maintained Lower Limits of Detection consistent with NRC
Regulatory Guide 4.14 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 new 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 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
6
N:\Required Reports\Semi Annual Effluent Reports\20ll Jan to
June\Jan_to_Jufl_2011_SemLannual_EffluenCReport_Main_text.docx
concentrations of radioactive dust and radon at individual receptor locations around the
Mill.
The MILDOS and MILD OS 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 100 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 mrernJyr 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% VzOs) and Arizona Strip ore (0.637%
U308). 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 1st and 2nd quarters of 2011
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-l, 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-1, BVH-2, BVH-4, BVH-5 and BHV-6 are within regulatory limits. BHV-1 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 rnrem/yr for combined internal and external exposure.
4.0 VE(iETATION SAMPLES
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 2011 grazing season, two sets of samples have been
collected to date, on June 23, 2011 and in July 2011. A third set of samples is planned
for the fall season. At the conclusion of the third quarter of 2011, three sets will have
been collected consistent with Regulatory Guide 4.14. The data from the June 2011
sampling is included in the current January to June 2011 Semi-Annual Effluent Report
("SAER"). Data from the July and fall sampling will be included in the July to
December 2011 SAER.
Section 4.2 of the Mill's Environmental Protection Manual states that vegetation samples
are to be collected during the early spring, late spring and fall (i.e., the growing seasons).
During the January to June 2011 period, the early spring samples were inadvertently
omitted. The late spring sample was collected just past the end of spring (on June 23,
2011). An additional summer sample was collected in July 2011 in place of the omitted
early spring sample. As a result, as discussed above, three samples will have been
collected by the end of the 2011 grazing season meeting the requirements of NRC
Regulatory Guide 4.14.

5.0 STACK SAMPLING
Vnder Section 5.0 of Tab 1.4 of the Mill's Environmental Protection Manual, Revision:
DVSA-1, 2/07 (the "Environmental Protection Manual") gas stack samples are collected
at the Mill in accordance with the calendar year schedule shown below:

The yellowcake dryer, yellowcake baghouse, and grizzly operated during the 2nd quarter
of2011.
The analytical results of stack sampling conducted for the 1st and 2nd Quarter of 2011, as
well as for the 3rd and 4th Quarters of 2010, are provided in Table 8 below, indicating the
uCi/cc concentration in the stack emissions and the stack's radionuclide release rate
(uCi/sec) for V-Nat, Th-230, Ra-226 and Pb-21O at each of the stacks sampled. The
actual analytical results reported by the laboratory for the 1st and 2nd quarters of 2011 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 2011 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 total
dissolved solids (TDS) and total suspended solids (TSS) quarterly and 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
during both the 1 st and 2nd quarter and for the dissolved and suspended radionuclides
noted above during the 2nd quarter.
Cottonwood Creek is an intermittent ephemeral drainage located southwest and down-
gradient of the Mill complex. Westwater Canyon is a drainage located west of the Mill
facility, which is rarely flowing. The field data sheets for the surface water sampling
attempts, along with graphs showing historic results are included as Attachment H.
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 2011 and will
be discussed in the July through December 2011 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, 2011. This information is retained at the Mill site for agency review.

CLIENT: Denison Mines USA Corp
Project: 1 st Quarter BHV Air 2011 Report Date: OS/29/11
Sample Delivery Group: Cll040259 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL{S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
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 ND (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.

Sample Delivery Group: C11070215 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
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 ND (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.

Sample Delivery Group: C11 061059 CASE NARRATIVE
BRANCH LABORATORY SUBCONTRACT ANALYSIS
Tests associated with analyst identified as ELI-CS were subcontracted to Energy Laboratories, 415 Graham Rd., College
Station, TX, EPA Number TX01520.
ORIGINAL SAMPLE SUBMITIAL(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 ND (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.

INTRODUCTION
Test Purpose
This test project was conducted to determine the total radionuclide emissions from the North
Yellow Cake Scrubber and the Yellow Cake Dryer Baghouse exhausts in terms of Curies per dry
standard cubic foot (Ci/dscf).
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 Dryer Baghouse. The Packaging enclosure also discharges into the 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 serve 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 Dryer February 15,2011 and one run on February 16th•
One run was completed on the Dryer Baghouse February 15,2011.
Pollutants Tested and Methods 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.

The process was operated according to standard procedures. All pertinent process data was
available for recording by agency personnel. Scrubber water flow, pressure drop readings (~p)
were recorded and are found in Appendix D. The Dryer Baghouse pressure drop readings (~p)
were recorded and are found on the test run sheets. Production data will be submitted by Denison
Mines.
Description of Collected Samples
The test filters for the North Yellow Cake Scrubber were heavily covered with a white or pinkish
white colored particulate. The front washes were clear in appearance.

SAMPLING AND ANALYSIS PROCEDURES
Sampline Port Location
The inside diameter of the North Yellow Cake Scrubber stack is 18.0 inches. The two, four-inch
diameter 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 1 in Appendix D is a
schematic of the stack.
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.
Samplin2 Point Location
Table III shows the distance of each sampling point from the inside wall according to EPA
Method 1. Each point is marked and identified with a wrapping of glass tape and numbered.
These points are determined by measuring the distance from the inside wall.

Samplin2 Train Description
To determine the actual emission rates for this stack, 40 CFR 60, Appendix A, Methods 1-5/114
were followed.
All sampling trains were made of inert materials, (Teflon, stainless steel and glass) to prevent
interference of the sampled gas and particulate.

Uncertainty Estimation
TestAmerica Richland has adopted the internationally accepted approach to estimating
uncertainties described in "NIST Technical Note 1297, 1994 Edition". The approach, "Law of Propagation
of Errors", involves the identification 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
* f(x,y,z, ... ). The components (x,y,z) are evaluated to determine their contribution to the overall method
uncertainty. The individual component uncertainties (uJ 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 B, evaluated by other means. Uncertainties not included in the
components, such as sample homogeneity, are combined with the component uncertainty as the square root
of the sum-of-the-squares of the individual uncertainties. The 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 (S17n), where S is the standard deviation of the
derived results. The type B uncertainties are all other random or non-random components that are not
included in the standard deviation.
The derivation ofthe general "Law of Propagation of Errors" equations and specific example are
available on request.

Report Definitions
An agreed upon activity level used to trigger some action when the final result is greater than or equal to the Action
Level. Often the Action Level is related to the Decision Limit.
The QC preparation batch number that relates laboratory samples to QC samples that were prepared and analyzed
together.
Defined by the equation (ResultlExpected)-1 as defined by ANSI NI3.30.
Chain of Custody Number assigned by the Client or TestAmerica.
Poisson counting statistics of the gross sample count and background. The uncertainty is absolute and in the same
units as the result. For Liquid Scintillation Counting (LSC) the batch blank count is the background.
All known uncertainties associated with the preparation and analysis of the sample are propagated to give a measure
of the uncertainty associated with the result, Ue the combined uncertainty. The uncertainty is absolute and in the
same units as the result.
The coverage factor defines the width of the confidence interval, 1,2 or 3 standard deviations.
Contractual Required Detection Limit as defined in the Client's Statement Of Work or TestAmerica "default"
nominal detection limit. Often referred to the reporting level (RL)
Decision Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume
associated with the sample. The Type I error probability is approximately 5%. Lc=(1.645 *
Sqrt(2*(BkgmdCntlBkgmdCntMin)/SCntMin» * (ConvFct/(Eff*Yld*Abn*Vol) * IngrFct). For LSC methods the
batch blank is used as a measure of the background variability. Lc cannot be calculated when the background count
is zero.
The number assigned by the LIMS software to track samples received on the same day for a given client. The
sample number is a sequential number assigned to each sample in the Lot.
Detection Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume
with a Type I and II error probability of approximately 5%. MDC = (4.65 *
Sqrt«BkgmdCntlBkgmdCntMin)/SCntMin) + 2.71/SCntMin) * (ConvFctl(Eff * Yld * Abn * Vol) * IngrFct). For
LSC methods the batch blank is used as a measure of the background variability.
The instrument identifier associated with the analysis of the sample aliquot.
The U-234 result divided by the U-238 result. The U-234/u-238 ratio for natural uranium in NIST SRM 4321C is
1.038.
Ratio of the Result to the MDC. A value greater than I may indicate activity above background at a high level of
confidence. Caution should be used when applying this factor and it should be used in concert with the qualifiers
associated with the result.
Ratio of the Result to the Total Uncertainty. If the uncertainty has a coverage factor of2 a value greater than I may
indicate activity above background at approximately the 95% level of confidence assuming a two-sided confidence
interval. Caution should be used when applying this factor and it should be used in concert with the qualifiers
associated with the result.
Sample Identifier used by the report system. The number is based upon the first five digits of the Work Order
Number.
The equation Replicate Error Ratio = (S-D)/[sqrt(TPUs2 + TPUd2)] as defined by ICPT BOA where S is the original
sample result, D is the result of the duplicate, TPUs is the total uncertainty of the original sample and TPUd is the
total uncertainty of the duplicate sample.
Sample Delivery Group Number assigned by the Client or assigned by TestAmerica upon sample receipt.
The sum of the reported alpha spec results for tests derived from the same sample excluding duplicate result where
the results are in the same units.
The LIMS software assign test specific identifier.
The recovery of the tracer added to the sample such as Pu-242 used to trace a Pu-239/40 method.

INTRODUCTION
Test Purpose
This test project was conducted to determine the total radio nuclide emissions from the North
Yellow Cake Scrubber, Yellow Cake Dryer Baghouse, and Grizzly Baghouse exhausts in terms
of Curies per dry standard cubic foot (Ci/dscf).
These tests were for U-Nat and Th-230 on the Grizzly Baghouse and U-Nat, Th-230, Ra-226,
and Pb-21O 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 scrubbers. Both dryer enclosures discharge
into the Dryer Baghouse. The Packaging enclosure also discharges into the 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 serve as the main
dust control device for the raw ore unloading and conveying to the processing building.
Stack schematics are shown as Figures 1 though 3 in Appendix D.
Test Dates
One run was completed on the Grizzly Baghouse May 24,2011.
One test run was completed on the NYC Dryer May 25 2011 and one run on the 26 th.
One run was completed on the Dryer Baghouse May 27,2011.
Pollutants Tested and Methods Applied
The tests were a determination of radio nuclide 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
Sampling Port Location
The inside diameter of the North Yellow Cake Scrubber stack is 18.0 inches. The two, four-inch
diameter 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 1 in Appendix D is a
schematic of the stack.
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.
The inside diameter of the Grizzly Baghouse stack is 18.75 inches. There are two, three-inch
diameter sample ports located 2.56 diameters (48 inches) downstream from the last disturbance
and 1.31 diameters (24.5 inches) upstream from the next disturbance. The sample port locations
are depicted in Figure 3 in Appendix D.
Sampling Point Location
Table III shows the distance of each sampling point from the inside wall according to EPA
Method 1. Each point is marked and identified with a wrapping of glass tape and numbered.
These points are determined by measuring the distance from the inside wall.

Sampling Train Description
To determine the actual emission rates for this stack, 40 CFR 60, Appendix A, Methods 1-5/114
were followed.
All sampling trains were made of inert materials, (Teflon, stainless steel and glass) to prevent
interference of the sampled gas and particulate.
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 5/114.
Sampling and Analytical Procedures
All sampling and analytical test procedures were as specified in 40 CFR 60, Appendix A,
Methods 5/114.
Quality Assurance
All equipment set-up, sampling procedures, sample recovery and equipment calibrations were
carried out according to the procedures specified in 40 CFR 60 and the Quality Assurance
Handbook/or Air Pollution Measurement Systems.

section.
V. Comments
Alpha Spectroscopy
Thorium-228, 230, 232
The achieved MDA of the samples exceeds the detection limit. However, in most cases, the activity of
the 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 three of the
four samples. Data is accepted. Except as noted, the LCS, batch blank, sample and sample duplicate
results are within acceptance limits.
Gamma Spectroscopy
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. There is no sample volume remaining for re-analysis.
Data is reported. Except as noted, the LCS, batch blank, sample and sample duplicate results are within
acceptance limits.
Alpha Scintillation
Radium-226
The achieved MDA exceeds the detection limit due to sample volume available for analysis. 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 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

Uncertainty Estimation
TestAmerica Richland has adopted the internationally accepted approach to estimating
uncertainties described in "NIST Technical Note 1297, 1994 Edition". The approach, "Law of Propagation
of Errors", involves the identification 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
* f(x,y,z, ... ). The components (x,y,z) are evaluated to determine their contribution to the overall method
uncertainty. The individual component uncertainties (Ui) 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 B, evaluated by other means. Uncertainties not included in the
components, such as sample homogeneity, are combined with the component uncertainty as the square root
of the sum-of-the-squares of the individual uncertainties. The uncertainty associated with the derived result
is the combined uncertainty (uc) 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 (Sf? n), where S is the standard deviation of the
derived results. The type B uncertainties are all other random or non-random components that are not
included in the standard deviation.
The derivation of the general "Law of Propagation of Errors" equations and specific example are
available on request.

Re ort Definitions
An agreed upon activity level used to trigger some action when the final result is greater than or equal to the Action
Level. Often the Action Level is related to the Decision Limit.
The QC preparation batch number that relates laboratory samples to QC samples that were prepared and analyzed
together.
Defined by the equation (Result/Expected)-l as defined by ANSI NI3.30.
Chain of Custody Number assigned by the Client or TestAmerica.
Poisson counting statistics of the gross sample count and background. The uncertainty is absolute and in the same
units as the result. For Liquid Scintillation Counting (LSC) the batch blank count is the background.
All known uncertainties associated with the preparation and analysis of the sample are propagated to give a measure
of the uncertainty associated with the result, Uc the combined ullcertainty. The uncertainty is absolute and in the
same units as the result.
The coverage factor defines the width of the confidence interval, I, 2 or 3 standard deviations.
Contractual Required Detection Limit as defined in the Client's Statement Of Work or TestAmerica "default"
nominal detection limit. Often referred to the reporting level (RL)
Decision Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume
associated with the sample. The Type I error probability is approximately 5%. Lc=(1.645 *
Sqrt(2*(BkgmdCntlBkgmdCntMin)/SCntMin» * (ConvFctl(Eff*Yld*Abn*Vol) * IngrFct). For LSC methods the
batch blank is used as a measure of the background variability. Lc cannot be calculated when the background count
is zero.
The number assigned by the LIMS software to track samples received on the same day for a given client. The
sample number is a sequential number assigned to each sample in the Lot.
Detection Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume
with a Type I and II error probability of approximately 5%. MDC = (4.65 *
Sqrt«BkgmdCnt/BkgmdCntMin)/SCntMin) + 2.71/SCntMin) * (ConvFct/(Eff * Yld * Abn * Vol) * IngrFct). For
LSC methods the batch blank is used as a measure of the background variability.
The instrument identifier associated with the analysis of the sample aliquot.
The U-234 result divided by the U-238 result. The U-234/u-238 ratio for natural uranium in NIST SRM 432lC is
1.038.
Ratio of the Result to the MDC. A value greater than I may indicate activity above background at a high level of
confidence. Caution should be used when applying this factor and it should be used in concert with the qualifiers
associated with the result.
Ratio of the Result to the Total Uncertainty. If the uncertainty has a coverage factor of2 a value greater than 1 may
indicate activity above background at approximately the 95% level of confidence assuming a two-sided confidence
interval. Caution should be used when applying this factor and it should be used in concert with the qualifiers
associated with the result.
Sample Identifier used by the report system. The number is based upon the first five digits of the Work Order
Number.
The equation Replicate Error Ratio = (S-D)/[sqrt(TPUs2+ TPUd2)] as defined by ICPT BOA where S is the original
sample result, D is the result of the duplicate, TPUs is the total uncertainty of the original sample and TPUd is the
total uncertainty of the duplicate sample.
Sample Delivery Group Number assigned by the Client or assigned by TestAmerica upon sample receipt.
The sum of the reported alpha spec results for tests derived from the same sample excluding duplicate result where
the results are in the same units.
The L1MS software assign test specific identifier.
The recovery of the tracer added to the sample such as Pu-242 used to trace a Pu-239/40 method.

Sample Delivery Group: C11030344 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITIAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2"C)
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 ND (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: Semi-Annual Surface Water 2011 Report Date: 06/23/11
Sample Delivery Group: C11050696 CASE NARRATIVE
TH230 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.
RA226 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 SUBMITIAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
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.
