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.
UTl900479 (the "License") and guidelines developed by the United States Nuclear
Regulatory Commission ("NRC") (NRC Regulatory Guide 4.14, Radiological Ejjluent
and Environmental Monitoring at Uranium Mills-Rev. ], 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 -I and BHV -2 (north), BHV-5
(east), and BHV-4 (south). BHV-I serves as a surrogate for the nearest
resident (BHV -I 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 -I ,
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:\Rcquircd Rcports\Semi Annual Emucnt Reports\20 10 July to
Dcc\Jul_lo _Dec _20 10_ Semi_ annual_ Effiucnl_Rcport_Main_lcxt.docx
f) Groundwater (up and down gradient) of the Mill facility; and 1
g) Seeps and springs in the vicinity of the Mil!.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 -I, 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 Mil!. 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 is 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 July through December, 2010 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 QA/QC 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 Ptrescribed detection limit « 1 x 10-16 uCi/ml) and missing values
were plotted as 1 x 10-6 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-21 0 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-21 0 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:\Rcquired Rcports\Semi Annual Effluent Reports\2010 July to
DecVul_ to_Dec _20 10_ Semi _ annuaJ_ Emucnt_ RcpoI1_Main_texLdocx
products of Rn-222 attach to ambient dust particles found naturally in the atmosphere and
are carried with the air. Pb-21 0 is the longest lived of these decay products and is the
decay product ofthe 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-2l0 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 I
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-21 0 was measured
at the Mill site to be I.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 ALARA 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 R313-15-30 I 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:\Rcquircd Rcports\Scmi Annual Emucnt Rcports\2010 July to
Dcc\JuUo _Dec _20 10_ Scmi_annual_Emucnt_ Rcpol1_ Main _ tcxt .docx
concentrations of radioactive dust and radon at individual receptor locations around the
Mill.
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 mremlyr for air emissions excluding radon as set out in
R313-15-1 01 (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 g and 1.5% V 205) and Arizona Strip ore (0.637%
U30 g). 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 TED E of 2 mrem per year at the nearest resident (3 mrem per year at
the nearest potential residence, being the location of BHV -I 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 2010
utilizing passive integrating devices, thermo luminescent dosimeters ("TLD's"). These
dosimeters were located at each of the Mill's high-volume air sampling stations (BHV-I,
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 TLD
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-I, BVH-2, BVH-4, BVH-S and BHV-6 are within regulatory li mits. BHV-I is at
the location of the nearest potential residence. The nearest actual residence is
approximately 0.4 miles north of BHV -I. The annual individual member of the public
limit is 100 mremJyr for combined internal and external exposure.
4.0 VEGETATION SAMPLES
Vegetation samples are collected at three locations around the Mill property. The
sampling locations are: I) northeast, 2) northwest and 3) southwest of the Mill facility.
The vegetation samples are collected during early spring, late spring and fall (i.e., the
growing seasons). Graphical log-scale presentation of the vegetation sampling results for
this reporting period, together with the analytical results reported by the Mill's contract
laboratory (including QAlQC information) are included at Attachment F of this report.
The 3'd quarter data results are within the variation of previous sampling episodes.
5.0 STACK SAMPLING
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
at the Mill in accordance with the calendar year schedule shown below:

The analytical results of stack sampling conducted for the 1st and 2nd Quarter of2010, as
well as for the 3rd and 4th Quarters of20l0, 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-210 at each of the stacks sampled. The
actual analytical results reported by the laboratory for the yd and 4th quarters of 201 0 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 sampled in the first quarter 2010 and as such no sediment
sample was necessary during 2010. The surface water sample from Westwater Canyon is

N:\Rcquircd Rcports\Scmi Annual Emucnl Reports\20JO July to
DccVuUo _Dec _20 I 0_ Semi_ annua l_ Emucnl_ Report_Main _lCx.t.docx
discussed in the previous SAER dated August 31 , 2010. Under Part I of the Mill's
Environmental Protection Manual, surface water samples are required to be obtained
annually from Westwater Canyon and quarterly from Cottonwood Creek. 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
both 3'd and 4th quarter and for the dissolved and suspended radionuclides noted above
during the 4th quarter. Additional sampling was conducted during the 1st and 2nd Quarters
2010 as discussed in the previous SAER dated August 31 , 2010.
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-I , 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. All soil samples will be analyzed, on a dry basis,
for Ra-226 and U-nat.
Annual soil samples were collected by the Mill staff during August 2010 at the six air
monitoring stations. The results of these samplings indicate that soils at the air
monitoring stations remain low and within the range of typical background. A graphical
presentation of historical results for soils at the air monitoring stations, together with
analytical sample results for the August 2010 sampling are provided in attachment I.
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 July through
December,2010. This information is retained at the Mill site for agency review.

ORIGINAL SAMPLE SUBMITIAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
Report Date: 12/06/10
CASE NARRATIVE
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.
SOIUSOLID 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.

CASE NARRATIVE
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
th is method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
Th e 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 count ing should not exceed 8 days.
SOIUSOLID 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 ANALYS IS
Subcontracting of sample analyses to an outside laboratory may be required. II so, ENERGY LABORATORI ES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

Project: Lale Fall Vegelalion
Sample Delivery Group: Cl01 20777
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submitlals have been relurned with Ihe data package.
SAMPLE TEMPERATURE COMPLIANCE: 4'C (±2'C)
Report Date: 02/09/11
CASE NARRATIVE
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 waler melhod 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 avo id 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
Dala for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Arcclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYS IS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize ils
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 detennine 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/dscl).
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 I and 2 in Appendix D.
Test Dates
One test run was completed on the NYC Dryer August 24, 2010 and one run on August 251h
One run was completed on the Dryer Baghouse August 24, 20 I O.
Pollutants Tested and Methods Applied
The tests were a determination of radionuclide emissions in accordance with EPA Method 5/1 14.
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 (t.p)
were recorded and are found in Appendix D. The Dryer Baghouse pressure drop readings (t.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.
The test filters for the Yellow Cake Dryer Baghouse were lightly colored with a tan colored
particulate. The front wash was clear in appearance.

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 I 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-i nch
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.
Sampling Point Location
Table III shows the distance of each sampling point from the inside wall according to EPA
Method I. 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.
6
The stack analyzers used to conduct Methods 1-51114 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 51114 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 51114.
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
Handbookfor Air Pollution Measurement Systems.

INTRODUCTION
Test Purpose
This test project was conducted to determine the total radionuclide 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/dscl).
These tests were for U-Nat and Th-230 on the Grizzly Baghouse and U-Nat, Th-230, Ra-226,
and Pb-21 0 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 October 19,2010.
One test run was completed on the NYC Dryer December 7,2010 and one run on December 8th•
One run was completed on the Dryer Baghouse December 8,2010.
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.

SAMPLING AND ANALYSIS PROCEDURES
Samplin g 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 di sturbance. Figure I 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 I. 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 Procednres
All sampling and analytical test procedures were as specified in 40 CFR 60, Appendix A,
Methods 5/114.
Quality Assu rance
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 Pol/ution 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 tracer yield of sample 5642 RI Grizzly Filter and
Beaker is below acceptance limits. The data is repOlted. Except as noted, the LCS, batch blank and
sample results are within acceptance limits.
Uranium-234, 235, 238
The FWHM of sample 5677, 5678 RI NYC Filters and Beaker exceeds acceptance criteria due to the high
level ofanalyte in the sample. Broadening of the peaks is expected due to the low specific activity of the
Uranium. The spectrum was resolvable. 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-21O
The achieved MDA of the samples exceeds the detection limit due insufficient sample volume. Data is
accepted. 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 MDNDL in two of the three samples. The tracer yield of samples 5677, 5678 RI NYC
Filters and Beaker, 5679 R2 NYC Filters and Beaker were below acceptance limits. There is no more
sample volume available for re-analysis. The batch QC is within acceptance limits and indicates the
method is in control. Data is reported. Except as noted, the LCS, batch blank and sample results are
within acceptance limits.

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 Errorsll• 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 (ua 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 (u,) multiplied by the coverage factor (1,2, or 3).
When three or more sampl e 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 all other rand om 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.

ORIGINAL SAMPLE SUBMITIAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
Report Date: 09/17/10
CASE NARRATIVE
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 aJi seven are ND (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
