Gas Stack Samolins
The Mill was in abeyant operation from July 1, tlrough December 31,2003. Therefore no
stack could be sanpled, and no data collected during thisperiod. Forperiods when the Mill
stacks are operational, gas stack sampling information would "or"ratty be reported in TableI of this report.
Environmental Radiological and Efluent Monitoring Data
2.1I Environmental Radon
Radon 222 flr:rl. is not directly measured, at the Mill,s boundary by the use of TLDchips. IUSA demonstrates conformance to the revised limits and requirements of l0
CFR 20.1302 (b) (1) by use of computational methods.
Direct Radiation
Gamma exposure rates were determined for the third and fourth quarters of 2003
utilizing.passive integrating devices. Thermoluminescent (TLD) dosinrters were
located at each high volunrc air sarryling station: BHv-l, dtry-2, BHV-3, BHV-4
and BHV-S- Gamma data from location BHV-3 are used as backgrotrnd for directradiation because of its remoteness to the plant mill site (approximately 3.5 milesdistan - The ganrna exposure radiation results from this tocation are zubtracted from
lesults of other sample locations. Table II lists gamma e{posure rate measurementsforthe third and fourth quarters of2003,before and aftei a background correctionhas been applied to locations BHv-r, BHV-2, BHv-4 and Buv-s. It is noted,
}-row9ver, that a conparison of these data to the average gamrna eryosure rate .value
in mRenr/quarter at each location since 1988, indicatJs no increased trend in directradiation at any location Slight increases in gamna levels in the fourth quarter
relative to the third quarter are consistent with and within the range of historic
variations in levels.

2.3 Vegetation
Vegetation mnples are collected at tlree (3) locations around tlrc mill periphery. Thesampling locations are northeast, northwest and southwest of the mill acifity.vegetation samples are collected during early spring, late spring and fall (growth
seasons). Vegetation sample results are presented in Table III. A review of thesedata compared with resuhs of previous years indicates no increased trend in
concentratio n of Ra'226 or Pb2l 0 in vegetation growtlr. Resufts for the period are
consistent with and *ilhio the historic ranges in variation ofprevious rur.rptiog autu
levels. Laboratory results are includd in tlre attachments. Recent vegetatircn *opt"twere taken during a period of severe droWlrt in San Juan County, which has resuhed
in a scarcity ofvegetation to be sampled. This could impact .rnp*i*^ to previous
periods.

Note thatall values that are reported below LLD values are not plotted on these graphs. Valuesreported below LLD are by definition not quantifiabie.
Environmental Air Monitoring
Ths environrrrental air particulate monitoring progftm is conducted at the White MesaMill utilizing four high volume continuous air *pliog stations located as indicatedin Figr'e I attached. Data from BHV-3, which is;;3.5 miles from the Mill site,is used as background. with u.s. NRC approval, air sample station Blrv-3 is nolonger utilized to collect air particulat" autu because sufficient data have beenaccumulated at BHV-3 to apply conservative background corrections to the othersample location data. The resufts of radionuclide concentrations for air sa:nplinglocatiors BHV-I (approximately 0.5 miles south ofnearest residence), BHV-2, B.Irv:4, BHV-S' and BIIV-6 are presented in Table IV. A review of itre inforrnation,comparing results to those from previous years indicate no upward trends inradionuclide concentrations at any location. iaboratory rezults are included in theattachments.
Inadditionto the environmentalair mnpling locations, BIry-I, Brry-2, BHV_4, andBHV-S, which are air mnpling locations ."qui..o by the uitt,s u.s. NRC license, anenvironrnental air sampling nnnitor @Irv-6i was in$alled at the request ofthe WhiteMesa ute community. This air rnonitoring station began operation on July l, lgggand provides additional environnrntal air sanpte collectlion iutu uta location betweenthe M[ site ard the Write Mesa Ute Community. Environmental air monitoring datafor BHV-6 is also included in this report.

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 of
chloride, nickel, potassium, and natural uranium. Copies of each of the current control chart plots
for the White Mesa Mill groundwater Point of Compliance ("POC") quarterly monitoring dataare
provided in this section. These plots include data from the most recent quarterly POC sampling
event in November 2003.
The software used by IUSA to interpret this data draws graphical time-plots of the data for each
analyte, and then performs a series of statistical tests to determine if it can draw a control chart for
that analyte.
1.The software first checks how much of the data is above detection levels for the analyte. If
25 percent or more of the data is below detection limits, the software will not draw a control
chart 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 me above detection
limits), 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 serial
correlation." If the data passes this test, the software proceeds with a third test.
The software lastly checks whether the data has a normal (bell-shaped or "Gaussian")
distribution. If it does not, the software will not draw a control chart and will draw a graphic
plot with the label "Variability does not appear Gaussian." If the data passes this test (is
normal 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 or
more extemal practical tests to the resulting graphic plot to determine whether or not the analyte is
in 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 samenumeric value. The natural uranium activities in WMMW-5 and 11, among others, exhibit
this repetition of similar or identical values over time. In each case, the data plot of the actual
activity is a line of nearly horizontal slope, and the software is unable to draw a control chart. This
graphic output does not mean the plotted parameter is out of control - it merely indicates the activity
of natural uranium at each of these locations has not been changing over the time interval sampled
and plotted.
If the data does not pass the randomness test, whether the results are static or exhibit a trend up or
down, and the graph contains the label "High serial correlation," this likewise does not mean that
the plotted parameter is out of control. For example, the plotted chloride and potassium
concentrations in WMMW-lz, whether viewed as the actual concentration, the square root of the
concentration, or the log,o of the concentration, exhibit a gradual downward slope. This graphic
output does not mean that the plotted parameters are out of control. These parameters were in
control, as indicated by previous control charts, in earlier sampling periods when their values were
higher than they are now. They ranain in control at the current lower concentration values as well,
even though the software cannot currently produce a control chart.

The control chart method is a parametric test, that is, statistically valid control charts can be drawn
and interpreted for the measured concentration of an analyte, 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 parameter that has a normal ("Gaussian") distribution.
In some cases, the parameter that exhibits a normal distribution is the measured concentration of
an analyte. In some cases, 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 concenkation,
log of concentration, or square root (0.5 power) of concentration, as appropriate, to generate either
a new conkol chart, or a graphic output that can be compared to an existing control chart for the
same parilmeter 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.
Chloride
Monitoring Well 5: This parameter is in control as indicated by the conhol chart.
Monitoring Well I l: This parameter is in control as indicated by the control chart.
Monitoring Well 12: The analytical results are not random (high serial correlation), hence a control
chart cannot be generated. The last period when the concentration data were
sufficiently random to generate a control chart (1i98), the upper control limit
on the chart was approximately 80 mg/L. The current concentration is within
the previously established upper control limit, hence the parameter is in
control.
Monitoring Well 14: This parameter is in control as indicated by the control chart.
Monitoring Well l5: This parameter is in control as indicated by the control chart.
Monitoring Well 17: This parameter is in control as indicated by the control chart.
Nickel
Monitoring Well 5: All analyical values are below detection limits. The parameter is in control.
Monitoring Well I 1: All analytical values are below detection limits. The parametsr is in control.

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
dishibuted to generate a control chart (1/99), the upper control limit on the
chart was approximately 20 mglL. The current logarithmic data is well within
the previously established upper control limit, hence the parameter is in
control.
The analytical results are not random (high serial correlation), hence a conhol
chart cannot be generated. The last period when the concentration data were
sufficiently random to generate a control chart(1199),the upper control limit
on the chart was approximately 18 mg/L. The current concentration is well
within the previously established upper control limit, hence the pmameter is
in control.
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 (2/00), the upper control limit on the
chart was approximately 17 mg/L. 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 dishibuted (not Gaussian), to generate a control chart-they've
been nearly constant. The last period when the logarithmic data were
sufficiently random and normally distributed to generate a control chart
(1/98), the upper control limit on the chart was approximately 37 pCr/L.T\e
current logarithmic results are well within the previously established upper
control limit, hence the parameter is in control.
The analytical results are not normally distributed (not Gaussian). Hetrce a
control chart cannot be generated. The last period when the logarithmic data
were sufficiently normally distributed to generate a control chart (8/00), the
upper control limit on the chart was approximately 68 pCi/L. The current
logarithmic data is within the previously established upper conhol limit,
hence the parameter is in control.
This parameter is in control as indicated by the control chart.
The analytical results are not sufficiently random (high serial correlation) to
generate a control chart. The last period when the logarithmic data were
sufliciently random to generate a control chart (1/98), the upper conhol limit
on the chart was approximately 63 pCilL. The current logarithmic results are
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 period when the concentration data were
sufficiently random to generate a control chart (6/01), the upper conhol limit
on the chart was approximately 57 pCilL. The current concenhation 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 period when the logarithmic data were
sufficiently random to generate a control chart (8/00), the upper conhol limit
on the chart was approximately 45 pCilL. The current logarithmic results are
within the previously established upper control limit, hence the parameter is
in control.
