Semi-Annual Effluent Monitoring Report for Period
July l, through December 3 l, 1998
Dear Sir/lVIadame:
As required by the Code of Federal Regulations, Title 10, Part 40..65,attached is semi-annual effluent
report for the White Mesa Mill, Blanding, Utah.
In addition to the attached information, as required by License Condition 11.3 C of NRC Materials
License SUA-1358, also provided is a summary of the environmental monitoring information for
monitoring wells WMMW-5, -11, -12, -14, -15 and -17 and other environmental sampling which will
assist in estimating the maximum potential annual radiation dose to the public. This information
covers the period from July 1 through December 31, 1998.
If you have any questions regarding this report, please contact Mr. Ron Berg or Mr. William Deal
at telephone number [phone].
Sincerely,
,(g r<zz
Ron E. Berg,
Radiation Safety Officer

Stack Sampling
No gas stack samples were collected on any White Mesa Mill efl-luent gas pollution control systems
for the period July I through December 3 1, 1998. The mill was in abeyant operations for the above
period and these systems were not operating. This information is generally reportcd in Table I,
however no data was collected during this period.
2.0 Environmental Radiological and Effluent Monitoring Data
Environmental Radon
Radon 222 flux measurements were not determined during this period at any location.
Specifically, ruC received a license amendment to the previous license, allowing
conformance to the limits and requirements of l0 CFR 20.1302 (b) (1) bV use of
computational methods and programs (MILDOSE modeling) to demonstrate the
compliance with regard to dose rate at the nearest residence.
Direct Radiation
Gamma exposure rates were determined for the third and fourth quarters of 1998
utilizing passive integrating devices. Thermo-luminescent dosemeters were located
at each high volume air sampling station: BHV-I, BHV-2, BHV-3, BFfV-4 and
BHV-5. The location of B[fV-3 is used as a background sample 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 iilustrates gamma exposure rate measurements for the third
and fourth quarters of 1998 after a background correction has been applied to
locations BHV-1, BHV-2, BHV-4 and BHV-S. A comparison of this data to the
average garnma exposure rate value in mRem/quarter at each location since 1988,
indicates no increased trend in direct radiation at any location.
Vegetation
Vegetation samples are collected at tkee (3) Iocations 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 Itr. A review of this data
comparing results of several previous years indicate no increased concentration of Ra-
226 or Pb-210 in vegetation growth. Laboratory results are attached.

Environmental Air Monitoring
The environmental air particulate monitoring program is conducted at the White Mesa
Mill utilizing four high volume continuous air sampling stations Iocated as indicated
in Figure 1.0 attached. High volume air sample station BI{V-3 is no longer utilized
to collect data for background correctional application to other sampling locations.
Sufficient data has been accumulated for making appropriate background corrections
to the other sample location data. The results of radionuclide concentrations for air
sampling locations BHV-I, BlfV-2 (nearest residence) BHV-4 and BHV-5 are
presented in Table ry. A review of the information, comparing results to those from
previous years indicate no anomalies. No potential upward trends in radionuclide
concentrations were found to exist at any location. Laboratory results are attached.
Ground Water Monitoring
The ground water monitoring program sample results for the third and fourth quarters
of 1998 are presented in Table V. Quality Control samples and Quality Assurance
samples are indicated on the respective quarterly results. Comparing these sample
results to those sample parameters which reflect Point of Compliance sampling
parameters ofthe previous years, indicate no apparent trends in analyte concentration
developing. Other informational data is presented on the respective Tables in order
to assist in evaluative assessment of potential trends.
Surface Water Monitoring
Surface water samples were collected for Cottonwood Creek and are presented in
Table \{I. Westwater Creek was sampled for a sediment soil sample in the second half
of 1998, however water did become available for a period of time after a storm event.
A sample of this water was collected. Both sediment and water sample data are
presented. Quality Control sampling data is also presented. No obvious analyte trend
is evident from comparison of previous data for Cottonwood surface water collection"
Laboratory results are attached.
Soil Sampling
Environmental soil samples have been collected at five (5) monitoring sample
locations during the period of July I through December 31, 1998. The sample results
for this period are attached. There were no unusual or upward trends in analyte
concentrations for these samples compared to historical data.
Meteorological Data
The semi-annual Meteorological Monitoring Report for the White Mesa Mill, July through
December 3l 1998, was ionducted by EnecoTech Environmental Consultants. This
information is retained at the Mill site for NRC review and inspection.
