Introduction
The White Mesa Mill ("the Mill") has established monitoring programs to evaluatecompliance with effluent limitations and to assess the potential for release of radioactivematerial into the local environment. These monitoring programs were developed andimplemented at the time of mill construction, operated *itt upp.opriate adaptation overtime, and remain consistent with the Mill's Radiroactive Materials ii""r." and guidelinesdeveloped by the Nuclear Regulatory Commission (U.S.N.R.c. negutaiory Guioe +.r+,Radiological Effiuent and Environmental Moniioring at [Jranium Mills-Rev. ],ML003739941), 1980).

1.0 Environmental Air Sampling
1.1 Program Overview
The environmental airborne particulate monitoring program at the White Mesa Mill (,,theMill") currently utilizes five air sampling stations. Four high-volume continuous air
sampling stations (BHV-l, BHV-2, BHV-4, and BHV-5) are required by the Mill,s
Radioactive Materials License. These sampling stations serye as sentinels for airborne
particulate which could potentially emanate from the Mill site. In addition to its general
site monitoring function, location BHV-I 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 theMilling operation. With the approval of the U.S. Nuclear Regulatory Commission and
effective November, 1995, this station (BHV-3) was removed from the active air
monitoring program. At that time, DUSA proposed (and the NRC determined) that a
sufficient air monitoring data base had been compiled at station BHV-3 to establish a
representative airborne radionuclide background for the Milling facility. 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, a sixth 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
1.2 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 bysite technicians weekly in accordance with the Mill's environmental air sampling
procedures and are composited on a quarterly basis for laboratory analyses. The
analytical parameters applied to the collected filters are: Uranium-Natural activity,
Thorium-230 activity, Radium-226 activity, and Lead-210 activity. In addition to the
requisite nuclide determinations, particulate loading is determined for each filter and
composited as a quarterly mass-loading estimate for review purposes only. Fugitive dust
standards for the facility are limited by the Mill's State of Utah air quality permit, which
sets a 20Yo visual opacity standard. The specific locations of the Mill's airborne
particulate monitoring stations are depicted on the attached figure, High Volume Air
Monitoring Stations (Attachment A). The analytical results of radionuclide particulate
sampling for each monitoring station operated during this July through December, 2007
reporting period are provided under separate sampling station attachment tabs beneath
Attachment A to this report (Tabs 1-6). Each Tab contains graphical illustrations of the
nuclide concentrations in log-scale presentation format. The graphs display reported data
over time since the 1981 inception of the Mill's environmental air monitoring program.

The actual analytical results (and associated QA/QC information) reported by the
laboratory are provided under Attachment B. It should be noted that for graphical
illustration pu{poses, valyes reported at zero, values reported at less than the prescribed
detection limit (< I 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 (e.g. data where detection
limits varied from 1 x 10-16 uCi/ml) the detection limit concentration was utilized for
plotting the data point. The reader should also note that this graphing convention is not
utilized to formulate station average information, nor is it intended as a precedent for data
treatment. Instead, the intent here is to provide a conservative viewable depiction of site
airborne nuclide information. The conservative nature of this format is founded in the
fact that the actual concentration below the detection limit can not be determined and, as
such, the plotted point is at a higher concentration than the actual activity concentration
of the collected sample.
In accordance with the above, the following environmental air sample station attachments
are provided with this report for the period:

The results of environmental air monitoring for this semi-annual period indicate that forall nuclides at all monitoring stations airborne radionuclide particulate activity
concentrations were well below regulatory Effluent Concentration Limits (ECL's) and
the Companies ALARA goals. It is noteworthy and expected that Pb-210 concentrations
are elevated when compared to the other parent nuclide concentrations (i.e. U-nat, Th-
230 and Ra-226). This phenomenon is due to the well-established controlling effect
experienced world-wide as a result of the ubiquitous presence of radon in the earth,s
atmosphere. Accordingly, elevated Lead-210 presence in disequilibrium with parent
nuclides measured here is not associated with uranium milling operations.
Radon-222 emanates as a decay-chain progeny of the Radium-226 contained in the soilof the earths crust and is dispersed generally throughout the earth's atmosphere. The
electrically charged short and long-lived decay products of Radon-222 attach to ambient
dust particles found naturally in the atmosphere and are carried with the air. Lead-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 nuclide 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, Lead-210 is commonly elevated and in disequibrium
when compared to parent nuclide activity, regardless of the Mill's presence. By way of
illustration, average ground-level concentrations have been reported for selected States
(NCRP Report 94, T992) and are summarized in Table 1 below, demonstrating elevated
Lead-210 activity where no uranium milling operations are located nearby. Lead-2lO
activity concentrations can be expected to be even higher for locations in the western
U.S. where uranium ore bodies are commonly located.
Table 1- NCRP Report 94-Global Lead-210 Concentration Example
1.4 Specific Sampling Station Data
The results of airborne particulate monitoring for the period (without background
subtraction) are provided by sampling station and nuclide in Tables 2-5 below. Along
with these data, the tables present comparative Effluent Concentration Limits (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 airbome particulate is well
controlled at the Mill. More specifically, in all cases the measured activity concentrations
were well within the ECL, as well as the Mill's ALARA Goal (i.e. 25oh of the ECL). In
fact, the data obtained since program inception in 1981 indicates that only one individual
quarterly measurement (TH-230 at BHV-5 for the 2"d qtr, 1996) has ever exceeded the
ECL at the Mill. With regard to this 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 annualized data that are of primary significance. In this
instance, the annualizedTh-230 data for BHV-5 in 1996 are well below the ECL for the
annual period.
In addition to these observations, evaluation of the data by comparison to the Mill's
ALARA Goals reveals that, with very few exceptions, the gross (background inclusive)
measurements also do not exceed the site's ALARA objectives which have been
established at 25o/o of the ECL (i.e. only 9 of the 2,064 gross nuclide determinations
exceeded the Mill's self-imposed ALARA threshold).

1.5 Radon-222
Due to the unavailability of monitoring equipment to detect the new 10 CRF Part 20
standard, and with the approval of NRC, Radon 222 monitoring at BHV stations was
discontinued in 1995. Instead, Denison demonstrated 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).
This calculation was 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 assumed the
Mill to be processing high grade Aizona Strip ores at full capacity, and calculated the
concentrations of radioactive dust and radon at individual receptor locations around the
Mill.
The MILDOS and MILDOS AREA codes calculated the combined Total Effective Dose
Equivalent (TEDE) from both air particulate and radon at the nearest potential residence,
approximately 1.2 miles north of the Mill, the public, as well as at all other receptor
locations. These calculations revealed projected doses to be below the ALARA goal of l0
mrem/yr for air particulate as set out in R3l3-15-101(4). Radon had also been calculated
to be within regulatory limits.
While confident that past modeling was sufficiently accurate, detection equipment has
improved since 1995. Accordingly, the Mill implemented Alpha Track monitoring for
radon at its environmental air monitoring stations commencing with the l't Quarter of
2007.
When evaluating alpha track data and compliance with the effluent concentration limit
for radon, two referenced limits are listed in the regulations. One limit (1x 10-10 uCi/ml or
0.1 pCi/l) is for instances where radon daughters are present with the radon, and are in
100% equilibrium with the parent Rn-222. The other listed concentration limit (1 x l0-8
uCi/ml or 10 pci/l) is applicable when radon daughters are not present. At the White
Mesa Mill, 100% equilibrium of radon progeny with parentRn-222 is unrealistic given
the short half lives of the nuclides considered and the short travel time to the monitoring
locations. Radon emanates from the ground (or mill tailings) without daughters present,
and the daughters grow in over time. It is therefore necessary to evaluate radon daughter
equilibrium at each air monitoring station utilizing site-specific wind speed and distance
information to derive site-specific Effluent Concentration Limits (ECL's). Such
disequilibrium situations and alternative calculations are anticipated by the regulations
and, in particular, R3 13- l5-302(3) provides a means by which the licensee may adjust the
effluent concentration values in Appendix B to 10CRF, Part 20 at table 2 (which are
incorporated by reference into R3l3-15-302(2)(bXD) to account for disequilibrium. The
regulatory purpose of such an adjustment is to appropriately take into account the actual
characteristics of the measured effluents, including radioactive decay equilibrium.

Toward this end, Denison utilized an established (EPA, 1986) outdoor equilibrium
formula to determine the appropriate Equilibrium Factor for use in calculating the ECL
for disequilibrium conditions. The EPA expression of the outdoor Equilibrium Factor
(EF) is derived by the following equation:
E F = |.0 - 0.047 9 expGt r t'z0t - z sg$exp(-/ / 38 6) + I .2442 expc t t 28 4)
[Where, t is the travel time in minutes (distance/wind speed)]
Once the Equilibrium Factor has been determined, the ECL for each air monitoring
station is determined by dividing the 0.1 pCi/l limit (for situations when daughters are
present in equilibrium) by the Equilibrium Factor (EF).
By utilizing this formula, Denison has determined the appropriate (equilibrium adjusted)
ECL's for each of its air monitoring stations. This information, the data inputs used to
determine the Equilibrium Factor, and the results of sampling for this report period are
shown in Table 6 below. It should be noted when observing the comparison between the
actual measurement value and the derived ECL that the derived ECL provides ample
protection for members of the public. More specifically, by utilizing current ICRP dose
conversion factors the ECL's established here represent approximately 25 mrem for a
continuous exposure at the monitoring stations. Therefore these values serve as an
ALARA goal and would yield doses well below the 100 rnrem standard for individual
members of the public. A comparison of measured radon-222 values against derived
ECL's is provided in Table 6 below and the analytical results provided by the laboratory
are included at Attachment D. It is noted that annual average radon-222 concentrations
were less than the derived evaluation values for 2007.

* These values include subtraction of the background concentrations measured at BHV-3.
2.0 External Radiation (Direct Gamma)
Gamma exposure rate estimates were measured for the third and fourth quarters of 2007
utilizing passive integrating devices, thermoluminescent dosimeters (TLD's). These
dosimeters were co-located at each of the license-required high-volume air sampling
stations 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 and attendant lack of potential for exposure from the Mill

The results for this period indicate that above background measurements for stations
BVH-I, BVH-2, BVH-4 and BVH-5 are well within regulatory limits. The annual
individual member of the public (IMOP) limit is 100 mrem/yr at the property boundary
for combined internal and external exposure. For this six month period, the maximum
above background quarterly external exposure estimate indicated by TLD measurement
was 4 mrem at BHY-2 (3'd Quarter) and BHV-5 (4nd Quarter;, wlll within the Mill's
ALARA goals.
3.0 Vegetation Samples
Vegetation samples are collected at three locations around the mill periphery. The
sampling locations are: l) Northeast, 2) Northwest and 3) Southwest of the Mill facility.
The vegetation samples are collected during early spring, late spring and fall (e.g. the
growing seasons). Graphical log-scale presentation of the vegetative radionuclide uptake
observed for this reporting period and results reported by the analytical laboratory
(including QA/QC information) are included at Attachment F of this report. The 2001
data compared to the results of previous years indicate no increase in uptake of Ra-226 or
Pb-210 in the vegetative growth collected and are within the variation of previous
sampling episodes. Trending of Radium-226 concentrations is generally down when the
entire period of record is considered, whereas, Lead-210 concentrations show no clearly
discernable trend. It should be noted that vegetation samples in recent years were
collected during a period of severe drought in San Juan County. For this reason sampling
was dramatically affected due to the scarcity of available vegetative species at the
respective sampling locations.
4.0 Stack Sampline
The Mill was in operation from July, through December of 2006. As such, processes
involving effluent control equipment and associated stack emissions (i.e., the yellowcake
dryer and baghouse) were operating during the report period. The analytical results of the

yellowcake stack sampling effort for this period are provided in Table 8 below, indicating
the uCi/cc release rate for the nuclides analyzed (U-nat, Th-230, Ra-226 and Pb-210
semiannually at both locations and uranium only at the yellowcake dryer for first
quarter). The actual analytical results and attendant QA/QC information reported by the
laboratory are provided in Attachment F to this report. It is 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 site boundary
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 putposes.
Table 8- Stack Effluent Concentration and Release Rate
5.0 Surface Water Monitoring
Surface water samples were collected from Cottonwood Wash during the 3'd and 4th
Quarters during this reporting period, however, Westwater Creek was not able to be
sampled because it was dry for the quarterly sampling events. The analytical results are
compiled in tabular format in Attachment H to this report. In addition, Attachment H
includes the actual results reported by the laboratory, as well as the attendant QA/QCinformation accompanying the laboratory's report. Cottonwood Wash is an intermittent
ephemeral drainage located southwest and down-gradient of the Mill complex.
Radionuclide data (U-Nat, Th-230 andRa-226) do not indicate trending over time nor are
influences from the Mill operations evidenced by the reported data.
6.0 Soil Sampline
Annual soil samples are collected by the Mill staff during the third quarter of each year
and are included at Attachment I. No discernable trend or impact from mill activities is
indicated by soil measurements for this reporting period.
