Gas Stack Sampling
The Mill was in abeyant operation from January 1,2004 through June 30, 2004. Therefore
no stack could be sampled, and no data collected during this period. For periods when the
Mill stacks are operational, gas stack sampling information would normally be reported in
Table I of this report.
Environmental Radiological and Effluent Monitoring Data
2.1 Environmental Radon
Radon 222 flilx is not directly measured, at the Mill's boundary by the use of TLD
chips. ruSA demonstrates conformance to the revised limits and requirements of 10
CFR 20.1302 (b) (1) bV use of computational methods.
2.2 Direct Radiation
Gamma exposure rates were determined for the first and second quarters of 2004
utilizing passive integrating devices. Thermoluminescent (TLD) dosimeters were
located at each high volume air sampling station: BHV-1, BHV-2, BHV-3, BHV-4
and BHV-5. Gamma data from location BHV-3 are used as background for direct
radiation because of its remoteness to the plant mill site (approximately 3.5 miles
distant). The gamma exposure radiation results from this location are subtracted
from results of other sample locations. Table II lists gamma exposure rate
measurements for the first and second quarters of 2004, before and after a
background correction has been applied to locations BHV-1, BHV-2, BHV-4 and
BHV-5. It is noted, however, thata comparison of these data to the average gamma
exposure rate value in mRem/quarter at each location since 1988, indicates no
increased trend in direct radiation at any location.
2.3 Vegetation
Vegetation samples are collected at three locations around the mill periphery. The
sampling locations are northeast, northwest and southwest of the mill facility.
Vegetation samples are collected during early spring, late spring and fall (growth
seasons). Vegetation sample results are presented in Table III. A review of these
data compared with results of previous years indicates no increased trend in
concentration of Ra-226 or Pb-210 in vegetation growth. Results for the period are
consistent with and within the historic ranges in variation of previous sampling data
levels. Laboratory results are included in the attachments. Recent vegetation
samples were taken during a period of severe drought in San Juan County, which has
resulted in a scarcity of vegetation to be sampled. This could impact comparisons
to previous periods.
Graphical representations of the vegetation sampling data for the White Mesa Mill
vegetation sampling locations since inception are included with this report. Note that

all values that are reported below LLD values are not plotted on these graphs.
Values reported below LLD are by definition not quantifiable.
Environmental Air Monitoring
The environmental air particulate monitoring program is conducted at the White
Mesa Mill utilizing four high volume continuous air sampling stations located as
indicated in Figure I attached. Data from BHV-3, which is some 3.5 miles from the
Mill site, is used as background. With U.S. NRC approval, air sample station BHV-3
is no longer utilized to collect air particulate data because sufficient data have been
accumulated at BHV-3 to apply conservative background corrections to the other
sample location data. The results of radionuclide concentrations for air sampling
locations BHV-1 (approximately 0.5 miles south of nearest residence), BHV-2,
BHV-4, BHV-5, and BHV-6 are presented in Table IV. A review of the information,
comparing results to those from previous years indicate no upward trends in
radionuclide concentrations at any location. Laboratory results are included in the
attachments.
In addition to the environmental air sampling locations, BHV-I, BI:IIy'-z, BHV-4, and
BHV-5, which arc air sampling locations required by the Mill's source material
license, an environmental air sampling monitor (BHV-6) was installed at the request
of the White Mesa Ute Communify. This air monitoring station began operation on
July 1, 1999 and provides additional environmental air sample collection data at a
location between the Mill site and the White Mesa Ute Community. Environmental
air monitoring data for BHV-6 is also included in this report.
Graphical representations of the air sampling data for the White Mesa Mill since
inception of the air sampling locations are included with this report. Note that all
values that are reported below LLD values are not plotted on these graphs. Values
reported below LLD are by definition not quantifiable.
Ground Water Monitorine
The ground water monitoring program sample results for the first and second
quarters of 2004 are presented in Table V. Quality Control samples and Quality
Assurance samples are indicated on the respective quarterly results. Analysis and
discussion of this information are included in Attachment I, Table V.
Surface Water Monitoring
Surface water samples were collected for Cottonwood Creek and are presented in
Table VI. Data utilized in generation of the surface water trend graphs, which
accompany this report, are reported in units of microcurie per milliliter (uCi/ml). No
obvious analyte trend is evident from comparison of previous data with Cottonwood
surface water samples collected for the current reporting period. The first and second
quarter sampling data laboratory results for Cottonwood Creek are attached.

Soil Sampling
Historically, annual soil samples are collected in the month of August, therefore this
report does not contain any soil sampling analysis data. Results of the 2004 White
Mesa Mill soil sampling data and their corresponding graphs will be presented in the
White Mesa Mill's Semi-Annual Effluent Report for the period of July l, through
December 31,2004.
Meteorological Data
As in prior reporting periods, an independent contractor, will prepare the White Mesa Mill
Semi-annual Meteorological Monitoring Report for the period of January 1,2004 through
June 30, 2004. This information will be retained at the Mill site for review and inspection.

The NRC February, 1992 Environmental Assessment states that the Mill will use the Shewhart-Cusum control chart technique for interpretation of quarterly groundwater data from analyses ofchloride, nickel, potassium, and natural u1aniry1. Copies of eaitr of the current control chart plotsfor the White Mesa Mill groundwater Point _of Compfiance ("POC") quarterly monitoring Oa1'a areprovided in this section. These plots include data from the most reclnt quarterly POC iamplingevent in May 2004.
The software used by IUSA to interpret this data draws graphical time-plots of the data for eachanalyte, and then performs a series of statistical tests to dJtermine if it can draw a control chart forthat analyte.
1.The software first checks how much of the data is above detection levels for the analye. If
25 percent or more of the data is below detection limits, the software will not draw a iontrolchart and will draw a graphic plot with the label "Control chart not tried. More than 25
Percent non-detects." If the data passes this test (75 percent of the values are above detectionlimits), the software proceeds with a second test.
The software then checks whether the data is random. If it finds the data not to be random,it will not draw a control chart, and will draw a graphic plot with the label "High seriaicorrelation." If the data passes this test, the software proceeds with a third test.
3. The software- pstJY checks whether the data has a normal (bell-shaped or "Gaussian")dishibution. If it does not, the software will not draw a control chart and will draw a graphicplot with the label *Variability does.not appear Gaussian." If the data passes thisiesi (isnormal or Gaussian), the software will draw a control chart
If the data does not pass one or more of the statistical tests and the software cannot draw a control
chart, it is not an indication that the analyte is out of control. A human interpreter can apply one ormore extemal practical tests to the resulting graphic plot to determine whether or not the'analfe isin control.
For example, if the data do-not pass the normality test, and the graph contains the label 'Variability
does not appear Gaussian," it may be due to the presence of a large number of sample results with
the same numeric value. The natural uranium activities in WMMW-5 and 11, among others, exhibitthis repetition of similar or identical values over time. In each case, the data pl6t of the actualactivity is a line of nearly horizontal slope, and the software is unable to draw a control chart. This
Praphic output does not qean the plottedparameter is out of control - it merely indicates the activityof natural uranium at each of these locations has not been changing over the iime interval sampled
and plotted.
If the data does not pass the randomness test, whether the results are static or exhibit a trend up ordown, and the gaph contains the label "High serial correlation," this likewise does not mean ihat
the plotted parameter is out of conkol. For example, the plotted chloride concentration in WMMW-
12, whether viewed as the actual concentration, the square root of the concentration, or the logls of
the concentration, exhibits a gradual downward slope-. This graphic output does not mean ttrit ttreplotted parameter is out of control. This parameter was in control, as indicated by previous control
charts, in earlier sampling periods when its value was higher than it is now. It remains in control atthe current lower concentration values as well, even though the software cannot currently produce
a control chart.

Similarly, in the case of the natural uranium activities in WMMW-I4, 15, and, 1.7, the plotted
parameters do not !.a!s th9 randomness test, due to various kends in the data, and eacti graph
contains the label "High serial correlation." The trends are present, and the software cannot generite
control charts for these wells, whether the data is viewed as the actual activity, the square root of the
activity, or the logle of the activity. As described above, if the data does not pass one of the
statistical tests, and the software cannot generate a control chart, it does not indicate that the
parameter is out of control. kr the case of the three wells mentioned above, the trend that prevented
generation of a control chart may appear upward when viewed over all the historii data, or
downward when viewed over the past l8 months or 6 sampling periods. However, all reported
values for each of these wells have remained within each welf i previous upper controi limit,
established when the data for each well was last random enough to generate a control chart. Hence,
natural uranium activities in all three wells remain in control.
The control chart method is a parametric test; that is, statistically valid control charts can be drawn
and interpreted for the measured concenhation of an analye, or for a mathematical function of the
analyte concentration. As stated above, one underlying assumption in this method is that the charts
and control limits be developed based on a parrmeter that has a normal ("Gaussian") distribution.
In some cases, the parameter that exhibits a normal distribution is the measured concentration of
an analye. In some c,Nes, the parameter that has a normal distribution is a mathematical functionof the measured concentration, such as the log, square root, or other power of the numerical
concentration value. The parameters used for White Mesa Mill data include measured concenfration,
log of concentration, or square root (0.5 power) of concentration, as appropriate, to generate either
a new control chart, or a graphic output that can be compared to an existing control chart for the
same parameter from a previous monitoring period.
A summary interpretation of the control charts for the groundwater analytical results for chloride,
nickel, potassium and natural uranium for this monitoring period is provided below.

The analytical results are not random (high serial correlation), hence a contolchart cannot be generated. The last period when the concentration data weresufficiently random to generate a contol chart (1/9g), the upper control limiton the chart was approximately 80 mglL. The currentconcentration is withinthe previously established upper control limit, hence the parameter is incontrol.

This parameter is in control as indicated by the control chart.
The analytical results are not sufficiently random (high serial correlation), or
normally distributed (not Gaussian), to generate a control chart. The last
period when the logarithmic data were sufficiently random and normally
distributed to generate a control chart (l/99), the upper control limit on the
chart was approximately 20 mgtL. The current logarithmic data is well within
the previously established upper control limit, hence the parameter is in
control.

The analytical results are not sufficiently random (high serial correlation), or
normally distributed (not Gaussian), to generate a control chart-they've
been nearly constant. The last period when the logarithmic data were
qufficiently random and normally distributed to generate a control chart(l/98), the upper contol limit on the chart was apprbximately 37 pcr/L.The
cu:rent ]ogarithmic results are well within the previously establiihed upper
control limit, hence the parameter is in control.
The analytical results are not normally dishibuted (not Gaussian). Hence a
control chart cannot be generated. The last period when the logarithmic data
were sufficiently normally distributed to generate a control ctrart 18/ooy, the
upper control limit on the chart was approximately 68 pCi/L. The current
logarithmic data is within the previously established upper control limit,
hence the parameter is in control.
The analytical results are not normally distributed (not Gaussian). Hence acontrol chart cannot be generated. The last period when the logarithmic data
were sufficie{tv normally distributed to generate a control ciat lzlo+1, the
upper control limit on the chart was approximately 30 pCi/L. The current
logarithmic data is within the previously established upper control limit,
hence the parameter is in control.
The analytical results are not sufficiently random (high serial correlation) togenerate a control chart. The last period when the logarithmic data were
sufficiently random to generate a conhol chart (l/98), the upper control limit
on the chart was approximately 63 pClL. The current logarithmic results are
within the previously established upper control limit, hence the parameter is
in control.
The anallical results are not sufficiently random (high serial correlation) to
generate a control chart. The last period when the c-oncentration data #ere
sufficiently random to generate a control chart (6/01), the upper conhol limit
on the chart was approximately 57 pCt/L. The current concentration is within
the previously established upper control limit, hence the parameter is in
control.
The analytical results are not sufficiently random (high serial correlation) to
generate a control chart. The last perilo when the"logarithmic data #ere
sufficiently random to generate a control chart (8i00), the upper control limit
on the chart was approximately 45 pCt/L. The current logarithmic results are
within the previously established upper control limit, hence the parameter is
