Addendum to Semi-Annual Effluent Monitoring Report January 1, 2010 through
June 30, 2010
This document is an addendum to the semi-annual effluent report for the period January through
June, 2010 (the "SAER") which was submitted to the Utah Department of Environmental
Quality Division of Radiation Control on September 1, 2010.
As explained in the SAER, the yellowcake drying and packaging areas operated only
sporadically throughout most of the second quarter of 2010. The Mill made extra attempts to
collect stack data for the second quarter and the stack sampling was conducted .June 22, through
June 24, 2010. Due to the operational circumstances which resulted in samples being collected
late in the quarter, the analytical laboratory was unable to deliver the analytical results at the time
ofthe initial SAER. The purpose of this addendum is to amend the SAER to include the second
quarter stack data.
If you have any questions or require any fiirther information, please contact the undersigned.
Yours truly.

ADDENDUM
WIDTE MESA URANIUM MILL
SEMI-ANNUAL EFFLUENT REPORT, JANUARY THROUGH JUNE, 2010
1. 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).
The Mill's semi-annual effluent reports provide the results of the specific monitoring and
sampling activities that were undertaken during the subject reporting period.
This document is an addendum to the semi-annual effluent report for the period January
through June, 2010 (the "SAER") which was submitted to the Utah Department of
Environmental Quality Division of Radiation Control on September 1,2010.
As explained in the SAER, the yellowcake drying and packaging areas operated only
sporadically throughout most of the second quarter of 2010. The Mill made extra
attempts to collect stack data for the second quarter and the stack sampling was
conducted June 22, through June 24, 2010. Due to the operational circumstances which
resulted in samples being collected late in the quarter, the analytical laboratory was
unable to deliver the analytical results at the time of the initial SAER. The purpose of
this addendum is to amend the SAER to include the second quarter stack data.
2. DESCRIPTION OF CHANGES AND ADDITIONS
a. The following paragraph should be included in Section 5 at the end of the second
to last full paragraph on Page 8 of the SAER.
"Subsequent to submission of this SAER, stack samples collected during the
second quarter 2010 sampling event for the yellowcake dryer and the
yellowcake baghouse were analyzed as required. The required second
quarter Stack Effluent Concentrations and Release Rates are provided in the
updated Table 8, below. As indicated in Table 7, semi-annual monitoring,
which is conducted in the first and third quarters, requires only analysis and
tabulation of these parameters for uranium. As identified in the updated
Table 8, data for these parameters for Th-230, Ra-226 or Pb-210 for the
third quarter of 2009 and first quarter of2010 are not required and have not
been included in Table 8."
1
b. The following paragraph should be deemed to replace the last paragraph on
page 8 in Section 5 of the SAER.
"The analytical results of stack sampling conducted for the first and second
Quarters of 2010, as well as for the third and fourth Quarters of 2009, 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 U-Nat, Th-
230, Ra-226 and Pb-21 0 at each ofthe stacks sampled. The actual analytical
results reported by the laboratory for the first and second Quarter of 2010
are provided in Attachment G to this report."
c. Table 8, provided below, should be deemed to replace the version of Table 8
in the SAER.

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/dscf).
These tests were for U-Nat, Th-230, Ra-226, and Pb-21 o.
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 test run was completed on the NYC Dryer June 22,2010 and one run on June 23 rd•
One run was completed on the Dryer Baghouse June 22, 2010.
One run was completed on the Grizzly Baghouse June 15,2010.
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,

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 sa!llpling 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
Handbookfor Air Pollution Measurement 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 "Comments"
section.
V. Comments
Alpha Spectroscopy
Thorium-228, 230, 232
Upon initial analysis, the tracer yields of the samples exceed the acceptance limits due to indigenous Th-
234 activity in the samples. The samples were re-counted and are now within acceptance limits. The
tracer value in the batch blank was incorrectly entered into the database. The Th-229 tracer activity
added to the blank was estimated based upon the activity values in the other tracers in the batch. 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 samples were counted for the maximum time frame appropriate for the
method. 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. 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's exceed the detection limit due to insufficient sample volume. Data is accepted.
Except as noted, the LCS, batch blank and sample results are within acceptance limits.
I certity that this Certificate of Analysis is in compliance with the SOW andlor 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 "N 1ST 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
>I< 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. Unceliainties not included in the
components, such as sample homogeneity, are combined with the component unceliainty as the square root
of the sum-of-the-squares of the individual unceliainties. 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 (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.

Report Definitions
An agreed upon activity level used to trigger some action when the final result is greater than orcqual to Ihe 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 N 13.30.
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, lte the combined uncertaillty. 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*(BkgmdCnt/BkgmdCntMin)/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 LoL
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 4321 Cis
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 [CPT 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 ofthe 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 LlMS 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.
