RE: Semi-Annual Effluent Monitoring Report for the period January 1, 2009 through June 30, 2009,
DRC Inspection Module EM-Ol, RML UTI900479.
Dear Mr. Landau,
An inspection was performed of the Semi-Annual Effluent Monitoring Report for the White Mesa Mill
in Blanding, Utah by representatives of the Division of Radiation Control (DRC). The inspection was
an examination of the effluent monitoring conducted at your facility as it relates to compliance with
the Utah Radiation Control Rules and the conditions of the license. The inspection consisted of
examination of the Semi-Annual Effluent Monitoring Report for the period January 1, 2009 through
June 30, 2009.
During this inspection, the items reviewed were found to be conducted in compliance with the
Utah Radiation Control Rules and requirements for this license. Please continue to remember that
radiation safety is the responsibility of the licensee. Thank you for cooperating in this matter.
If you have any questions or concems regarding this letter, please contact Kevin Carney at (801) 536-
4250.

INSPECTION REPORT
Inspection Module: Semi-Annual Effluent Monitoring Report (Module EM-Ol)
Inspection Location: DRC Office, Salt Lake City, Utah
Inspection Item: Semi-Annual Effluent Monitoring Report for Reporting Period January 1, 2009
through June 30, 2009.
Inspector(s): Kevin Carney
Personnel Contacted: Steven Landau, Manager, Environmental Affairs, Denison Mines
Governing Documents:
o White Mesa Environmental Protection Manual

o NRC Reg Guide 4.14, Radiological Effluent and Environmental Monitoring at Uranium

o 10CFR20 Table II of Appendix B
o Utah Radiation Control Rules R313
Inspection Summarv
Inspection Module EM-Ol was performed by review of the White Mesa Mill Semi-Annual Effluent
Monitoring Report for Reporting Period January 1, 2009 through June 30, 2009 which was received by
the DRC on August 31, 2009.
The inspection evaluated adherence to the Mill's procedures and compared the effluent monitoring
results with 10CFR20 limits, Utah Rules and Regulatory Guide 4.14 recommendations.
Findings
Utah Administrative Code R313-24-4, incoiporating by reference I0CFR40.65(a)(l), states:
(1) Within 60 days after January I, 1976 and July 1, 1976, and within 60 days after January 1
and July 1 of each year thereafter, submit a report to the Director of the Office of Nuclear
Material Safety and Safeguards, using an appropriate method listed in § 40.5, with a copy to the
appropriate NRC Regional Office shown in appendix D to part 20 ofthis chapter; which report
must specify the quantity of each ofthe principal radionuclides released to unrestricted areas in
licjuid and in gaseous effluents during the previous six months of operation, and such other
information as the Commission may require to estimate maximum potential annual radiation
doses to the public resulting from effluent releases.
The Report was submitted 62 days after June 30, 2009. However, the inspector does not want to cite
Denison Mines for the Report being only two days overdue.
The EM-Ol inspection for the previous period, July 1, 2008 through December 31, 2008, was found to
have several findings associated with it. There were reporting deficiencies due to quality control
problems with the laboratory that Denison Mines had contracted with and the DRC had issues with the
Page 1 of 2
radon sampling results (Alpha Track) which were reported. Denison Mines has since contracted with
another laboratory and has seemingly resolved the previous quality control concems. In the DRC's letter
to Denison Mines, dated July 16, 2009, it was requested that Denison discontinue reporting the measured
radon results in the Semi-Annual Effluent Monitoring Report since the results were not intended to be used
to demonstrate compliance. Denison has complied with this request and continues to cite the MILDOS
AREA modeling to demonstrate compliance with radon effluent limits.
There are no findings associated with the Semi-Annual Effluent Monitoring Report for Reporting Period
January 1, 2009 through June 30, 2009.
