SUBJECT: a""* and 3"^ Quarter, 2009 DUSA Groundwater Monitoring Reports: Ground Water
Quality Discharge Permit UGW370004: DRC Findings and Notice of
Enforcement Discretion
Dear Mr. Frydenlund:
The Utah Division of Radiation Control (DRC) received the 2"'' Quarter (April - June) and 3"^
Quarter (July - Sept.) 2009 Groundwater Monitoring Reports on September 1, 2009 and
December 2, 2009, respectively, (l" Quarter 2009 Report). After review of the 2"'' and 3"^, 2009
Quarterly Reports for the Denison Mines (USA) Corp. (DUSA) White Mesa Uranium Mill near
Blanding, Utah, the following issues were identified:
3"^^ Quarter Groundwater Monitoring Report Received Late
The DUSA 3'"'' Quarter, 2009 Groundwater Monitoring Report (3""^ Quarter 2009 Report) was
received by the Division of Radiation Control (DRC) on December 2, 2009, which is past the
December 1 due date. This is a violation of Part I.E. 1 of the Permit.
Notice of Enforcement Discretion
The Executive Secretary has decided to use enforcement discretion in this matter, in that, the
report was received one day late. Although DUSA has had this same problem in the past, DUSA
hasn't had this problem since the 3'^'' Quarter, 2007.
,rd As a result, the DRC will not pursue enforcement for DUSA failing to provide the 3 Quarter,
2009 Report by its due date (December 1) at this time, but will give DUSA the benefit of doubt
that all groundwater reports will be provided by their respective due date in the future. Please

ensure that compliance is achieved and maintained so as to avoid escalated enforcement action in
the future.
DUSA Analytical Laboratory Not Certified by State of Utah to Perform Test for
Tetrahydrofuran (THF)
DUSA failed to use an analytical laboratory that was certified by the State of Utah to perform
testing for THF under EPA Method 8260B in the 3"" Quarter (August), 2009 monitoring event.
AWAL perfonned testing for THF by EPA Method 8260C. This is a violation of Part I.E.5(c) of
the Permit and Section 8.2 and Table 1 of the DUSA QAP.
Notice of Enforcement Discretion
The Executive Secretary has decided to use enforcement discretion in this matter, in that, the
problem has already been pursued via a January 14, 2010 Payment Demand Letter under authority
ofthe November 14, 2007 Stipulated Consent Agreement.
Monitoring Wells Not Purged for Two Casing Volumes
As stated in Section 6.2.7(d)(v) ofthe DUSA QAP, two casing, volumes must be evacuated from
the well before the sample is collected. The DUSA QAP directs DUSA to first calculate the
amount of time to evacuate two casing volumes and then pump for that length of time. As shown
in the table below, DUSA failed to evacuate two casing volumes in 12 wells during both the 2"
Quarter (May) and S^** Quarter (August), 2009 monitoring events, and one well during each of the
April, June, July, and September 2009 accelerated monitoring events, for a total of 28 wells.

Section 6.2.7 (d)(v) of the DUSA QAP, states: "... If the well is purged to dryness or is purged
such that full recovery exceeds two hours, the well should be sampled as soon as a sufficient
volume of groundwater is available to fill sample containers... " The field sheets show that DUSA
pumped the wells for two hours and collected the samples. However, there was no mention that
any of these wells were purged to dryness on the field sheets. It appears DUSA assumed that
these wells would not be able to fully recover within two hours. However, no documentation has
been submitted by DUSA that shows that these wells won't fully recover in two hours. Therefore,
failure to excavate two casing volumes before collecting groundwater samples is in violation of
Section 6.2.7(d)(v) of the DUSA QAP and Part I.E. 1(a) of the Permit. On November 17, 2009,
DUSA was issued a NOV (Docket No. UGWG9-06) for failing to excavate two casing volumes in
13 wells before collecting groundwater samples during the January, February, and March 2009
monitoring events. In a December 23, 2009 response to the NOV, DUSA stated: "Samples were
collected in accordance with Sections 6.2.7.(d)(v) and 6.2.7.(d)(vi) ofthe QAP
during the 4' Quarter, 2009 event."
Notice of Enforcement Discretion
The Executive Secretary has decided to use enforcement discretion in this matter, in that, the
January, February, and March 2009 samples were collected prior to the December 23, 2009
DUSA commitment that this issue would be resolved commencing with the 4"^ Quarter, 2009
Groundwater Monitoring Report.
As a result, the DRC will not pursue enforcement for DUSA failing to evacuate two casing
volumes before collecting groundwater samples in 13 wells during the January, February, and
March 2009 monitoring events at this time, but will give DUSA the benefit of doubt that it has
"solved" the problem. Please ensure that compliance is achieved and maintained so as to avoid
escalated enforcement action in the future.

Stabilization of Indicator Field Parameters Not Reached Before Sample Collection
As stated in Section 6.2.7(d)(v) ofthe DUSA QAP: "purging is completed after two casing
volumes have been removed and the field parameters pH, temperature, specific conductance,
redox potential (Eh) and turbidity have stabilized to within 10% over at least two consecutive
measurements." The quarterly DUSA reports showed that the field parameters pH, temperature,
specific conductance, and redox potential (Eh) reached stabilization in each well before sample
collection in the April, 2"'' Quarter (May), June, July, 3'"'^ Quarter (August), and September, 2009
monitoring events. However, this is not tme for turbidity. As shown on the table below, there
were 9 wells in the 2"'' Quarter, one well in the April, one well in the June, 12 wells in the 3'^''
Quarter (August), one well in the July, and one well in the September 2009 monitoring events
where turbidity stabilization wasn't reached before sample collection. In each of these situations,
DUSA made 4 field measurements for turbidity, the two last of which are listed in the table below.
As can be seen, the company failed to reach a -\-l- 10% stability before sample collection.

Failure to reach stabilization for turbidity before sample collection is in violation of Section
6.2.7(d)(v) of the DUSA QAP and Part I.E. 1(a) of the Permit. On November 17, 2009, DUSA
was issued a NOV (Docket No. UGWG9-06) for failing to achieve stable turbidity conditions
before collecting groundwater samples in 17 wells during the February and March, 2009
monitoring events. In a December 23, 2009 response to the NOV, DUSA stated: "Samples were
collected in accordance with Sections 6.2.7.(d)(v) and 6.2.7.(d)(vi) ofthe QAP during the 4"
Quarter, 2009 event."
Notice of Enforcement Discretion
The Executive Secretary has decided to use enforcement discretion in this matter, in that, the
February and March, 2009 samples were collected prior to the December 23, 2009 DUSA
commitment that this issue would be resolved commencing with the 4'** Quarter, 2009
Groundwater Monitoring Report.
As a result, the DRC will not pursue enforcement for DUSA failing to allow field turbidity to
stabilize before collecting groundwater samples during the February and March, 2009 monitoring
events at this time, but will give DUSA the benefit of doubt that it has "solved" the problem.
Please ensure that compliance is achieved and maintained so as to avoid escalated enforcement
action in the future.

Review ofthe 2"" Quarter, 2009 (dated August 31, 2009) and 3'" Quarter, 2009
(dated December 1, 2009) Routine Groundwater Monitoring Reports
Groundwater Discharge Pennit (Permit) UG370004
Denison Mines (USA) Corp. (DUSA)
White Mesa Mill, Blanding, Utah
This is a summary ofthe 2"'' Quarter (April - June) and 3"* Quarter (July - September) 2009 sampling
events and all accelerated monitoring during those quarters as documented in the August 31, 2009 and
December 1, 2009 DUSA Reports, cited above. After review of both ofthese reports, DRC staff findings
are as follows: 1) The DUSA 2"'' Quarter, 2009 Groundwater Monitoring Report was received by its
respective due date (September 1). 2) 3rd Quarter, 2(X)9 Groundwater Monitoring Report was received by
the DRC past its due date of December 1, 2009. 3) Analytical Laboratory performing testing for DUSA
was not certified by State of Utah to perform analysis for THF. 4) Several monitoring wells were not
purged for two casing volumes before sample collection. 5) Stabilization of indicator field parameters was
not reached before sample collection 6) Certain QA/QC sample data problems are apparent. 7) Summary of
the apparent violations is also provided below.
LO Accelerated Monitoring and POC Wells Exceeding GWCL
When a monitoring well has a pollutant that exceeds a GWCL set forth in Table 2 of the Permit it is in
Probable Out of Compliance (POOC) status. DUSA is then required to immediately initiate accelerated
sampling of that pollutant (see Permit, Part LG. 1). When monitoring wells have parameters that have
exceeded the GWCL two or more consecutive times they may be: in Out of Compliance (OOC) status if
the contaminant concentration also exceeds the mean and second standard deviation, or statistically
significantly higher as determined by some EPA guidance (see Permit, Part I.G.2). However, in a Notice
of Violation (NOV) dated August 24, 2006, the DRC decided a parameter had to exceed the Ground Water
Quality Standard (GWQS) set forth in Table 2 of the Permit for two or more consecutive times to be in
OOC status. This process will continue until the Background Groundwater Quality Reports submitted on
December 29, 2006 and May 31, 2007) has been approved by the DRC.

2.0 ?/^ Quarter Groundwater Monitoring Report Received Late
The DUSA 3'^'' Quarter, 2009 Groundwater Monitoring Report was received by the Division of Radiation
Control (DRC) on December 2, 2009, which is past the December 1 due date. This is a violation of Part
I.F.I of the pemiit.
3.0 DUSA Analytical Laboratory Not Certified by State of Utah to Perform Test for THF
The THF certification problem was first identified by the DRC after a review of the 2"^* Quarter, 2006
Groundwater Monitoring Report. DUSA was notified of the THF problem in an August 31, 2007 NOV
(Docket No. UGW07-02). To resolve the continuing THF problem, the DRC and DUSA entered into a
Consent Agreement for Docket No. UGW07-02 on November 14, 2007.
In resolution of the August 31, 2007 DRC NOV and ORDER, DUSA agreed to the following (See
November 14, 2007 Consent Agreement):
• DUSA agrees to use an analytical laboratory certified by the State of Utah to perform analysis
for all analytes listed in Table 2 ofthe Permit for all groundwater monitoring performed after
January 1, 2008.
• In the event that DUSA fails to use a Utah certified analytical laboratory for any groundwater
monitoring, DUSA agrees to pay stipulated penalties in the amount of $500 per day for every
day after January 1, 2008.
On May 30, 2008 the DRC received the DUSA T' Quarter, 2008 (January - March) Groundwater
Monitoring Report. The January, 2008 monitoring event was the first event where DUSA committed to
meet the terms ofthe Consent Agreement. After reviewing the (January - March) analytical reports, it
appeared DUSA failed to use a Utah SHL certified analytical lab (Energy Labs - Casper) for analysis of
THF for the January and February, 2008 monitoring events. Enforcement for this problem was pursued via
a June 10, 2008 Notice to Pay Letter under authority ofthe November 14, 2007 Stipulated Consent
Agreement. Payment ofthe $1,000 penalty was received by DRC in a DUSA letter dated July 10, 2008.
Page 4
Starting with the 2"'' Quarter, 2008 Report, DUSA began sending THF samples to American West
Analytical Laboratories (AWAL) for analysis. After checking with Utah Bureau ofLahoratory
Improvement (BLI), it appears AWAL is no longer certified for THF. Tamara DeMorest from the BLI, let
the DRC know in a December 10, 2009 email that AWAL's certification for THF under EPA Method
8260C expired May 31, 2009. Tamara DeMorest's December 10, 2009 e-mail is included as Attachment
1-
This information was shared with DUSA in a conference call on December 22, 2009. DUSA called the
DRC later that day and said that they had talked with its laboratory. DUSA reported that AWAL claimed
this problem was due to an Utah SHL mistake and Tamara DeMorest would be contacting the DRC to
substantiate this claim. On December 29, 2009 the DRC called Tamara DeMorest to verify the claim.
Apparently, as explained by Ms. DeMorest, AWAL updated their certified method from 8260B to 8260C
on June 4, 2008. AWAL was certified by the SHL to perform analysis for THF under method 8260C, and
this certification ended on May 31, 2009. However, Section 8.2 and Table 1 ofthe DUSA QAP requires
that THF be analyzed under EPA Method 8260B. AWAL performed analysis for THF under method
8260G, this is a violation of Section 8.2 and Table 1 ofthe DUSA QAP and Part LE.l(a) ofthe Permit.
After discussions with Ms. DeMorest, it appears that DUSA used an analytical laboratory (AWAL) that
was both: 1) not certified after June 4, 2008 by the SHL to perform analysis for THF, and 2) was certified
to perform analysis for THF only under the required method 8260B (prior to June 4, 2008). This THF
problem spans over several quarterly reports: (3''' and 4* Qtr, 2008 and V\ 2"'', and 3''^ 2009). However,
the 3"* and 4*, 2008 reports have be closed out via an October 7, 2009 Settlement Agreement (UGW09-
04SA) and DUSA already been cited for problems found in the T' Quarter, 2009 Report under a November
17, 2009 NOV (Docket No. UGW09-06). It is recommended that the Executive Secretary use enforcement
discretion for the THF problems found in these reports, in that the Division's findings have already been
closed. However, the DRC should cite DUSA for the THF problems found in the 2"" and 3"* Quarter
Reports. To this end, the DRC issued a Demand for Payment letter on January 14, 2010 to enforce the
terms ofthe November 14, 2007 Consent Agreement.
During the 2"** Quarter (May), 2009 monitoring event, 28 THF samples were collected over a nine day
period (May 12 - 14, 16 - 21). AWAL performed analysis for all ofthe 28 THF samples. During the 3'^
Quarter (August), 2009 monitoring event, 19 THF samples were collected over an eight day period (August
10 - 13, 17-18, and 25 - 26). AWAL performed analysis for all of the 19 THF samples. Although the
laboratory is certified by the State of Utah Bureau ofLahoratory Improvement to perform volatile organics
analysis by EPA Method 8260C, it is not certified to perform testing for THE and Section 8.2 and Table 1
of the DUSA QAP requires that THF be analyzed under EPA Method 8260B. This is a violation of
Section 8.2 and Table 1 of the DUSA QAP and Parts I.E. 1(a) and I.E.5(c) of the permit.
4.0 Monitoring Wells Not Purged for Two Casing Volumes
As stated in Section 6.2.7(d)(v) ofthe DUSA QAP, two casing volumes must be evacuated from the well
before the sample is collected. The DUSA QAP directs DUSA to first calculate the amount of time to
evacuate two casing volumes and then pump for that length of time. As shown in the table below, DUSA
failed to evacuate two casing volumes in 12 wells during both the 2"'' Quarter (May) and 3'^'^ Quarter
(August), 2009 monitoring events, and one well during each ofthe April, June, July, and September 2009
accelerated monitoring events, for a total of 28 wells.

Section 6.2.7(d)(v) of the DUSA QAP, states: "... If the well is purged to dryness or is purged such that
fidl recovery exceeds two hours, the well should be sampled as soon as a sufficient volume of groundwater
is available to fill sample containers... " The field sheets show that DUSA pumped the wells for two hours
and collected the samples. However, there was no mention that any of these wells were purged to dryness
on the field sheets. It appears DUSA assumed that these wells would not be able to fully recover within
two hours. However, no documentation has been submitted by DUSA that shows that these wells won't
fully recover in two hours. Therefore, failure to excavate two casing volumes before collecting
groundwater samples is in violation of Section 6.2.7(d)(v) of the DUSA QAP and Part I.E. 1(a) of the
Permit. This problem was also found when DRC staff reviewed the T' Quarter, 2009 DUSA groundwater
monitoring report. In that instance, the problem was brought to the company's attention in a November 17,
2009 NOV (Violation No. 3). DUSA responded to that action with a December 23, 2009 letter, which is
currently in review.

5.0 Stabilization of Indicator Field Parameters Not Reached Before Sample Collection
As stated in Section 6.2.7(d)(v) ofthe DUSA QAP: "purging is completed after two casing volumes have
been removed and the field parameters pH, temperature, specific conductance, redox potential (Eh) and
turbidity have stabilized to within 10% over at least two consecutive measurements." The quarterly DUSA
reports showed that the field parameters pH, temperature, specific conductance, and redox potential (Eh)
reached stabilization in each well before sample collection in the April, 2"'' Quarter (May), June, July, 3"*
Quarter (August), and September, 2009 monitoring events. However, this is not true for turbidity. As
shown on the table below, there were 9 wells in the 2"** Quarter, one well in the April, one well in the June,
12 wells in the 3"* Quarter (August), one well in the July, and one well in the September 2009 monitoring
events where turbidity stabilization wasn't reached before sample collection. In each ofthese situations,
DUSA made 4 field measurements for turbidity, the two last of which are listed in the table below. As can
be seen, the company failed to reach a +1- 10% stability before sample collection.

Failure to reach stabilization for turbidity before sample collection is in violation of Section 6.2.7(d)(v) of
the DUSA QAP and Part I.E. 1(a) ofthe Permit. This problem was also found when DRC staff reviewed
the r' Quarter, 2009 DUSA groundwater monitoring report. In that instance, the problem was brought to

6.0 Groundwater Samples Collected with Turbidity Measurement > 5 NTU
As stated in Section 6.2.7(d)(v) ofthe DUSA QAP: "... turbidity measurement in the water should be 5
NTU prior to sampling unless the well is characterized by water that has a higher turbidity. " During the P'
Quarter, 2009 (February) monitoring event, the Field Data Worksheet for monitoring wells MW-24 and
MW-32 showed that groundwater samples were collected above the 5 NTU standard (see table below).

Failure to collect groundwater samples below the 5 NTU standard is a concem in that excess turbidity has
the potential to bias groundwater quality analytical results. Section 6.2.7(d)(v) ofthe DUSA QAP needs
improvement, in that its current wording "...turbidity measurement in the water should be < 5 NTU prior to
sampling..." needs to be strengthened in the next version ofthe DUSA QAP to make it a requirement
before sample collection.
7.0 Previous Monitoring Events QA/QC Sample Data Problems
QA/QC problems found in the P' Quarter, 2009 groundwater monitoring events showed a number of issues
of non-compliance with the DUSA QAP (for details see July 14, 2009 DRC Memo). These antecedent
problems were identified in previous DRC documents, and included:
• The March, 2009 Trip Blank was lost due to an analytical equipment error. Therefore, there were
not any March, 2009 Trip Blank results to compare to the original sample results for 11 VOC
parameters in three wells. This is in violation of Section 9.13 of the DUSA QAP and Part I.E. 1(a)
of the Permit.
• DUSA failed to evacuate two casing volumes before collecting groundwater samples in 13 wells
during the January, February, and March monitoring events. This is in violation of Section
6.2.7(d)(v) ofthe DUSA QAP and Part LE.l(a) ofthe Permit.
DUSA failed to allow field turbidity to stabilize before collecting groundwater samples in 17 wells
during the February and March monitoring events. This is in violation of Section 6.2.7(d)(v) of the
DUSA QAP and Part I.E. 1(a) of the Permit.
Page 8
• DUSA failed to measure for field turbidity in wells MW-14 and MW-32 for the January, 2009
monitoring event and wells MW-20 and MW-22 for the Febmary, 2009 monitoring event. This is
in violation of Sections 6.2.2(a) and 6.2.7(d)(v) of the DUSA QAP and Part I.E. 1(a) of the Permit.
• The 1" Quarter, 2009 Water Table Contour Map was created with elevation data that was not
contemporaneous, i.e. collected within 5 calendar days or less. This map was in violation of
Section 11 of the DUSA QAP and Part I.E. 1(a) of the Permit.
• During the T' Quarter, 2009 monitoring event. Relative Percent Difference was greater than 20%
in original sample ((MW-11, 138 /ig/L) compared to duplicate sample (MW-70, 110 fig/L) for
thallium (22.58%), see Table 6. This QA/QC problem was in violation of Section 9.1.4(a) ofthe
QAP. The DRC policy when dealing with RPD is as followed (see 1/10/08 DRC Letter, p.2 and
4):
1) When DUSA submits an original and duplicate sample to the DRC for reporting purposes, the
DRC will use the sample with the highest concentration submitted to determine compliance.
2) Starting with the submittal of the 4* Quarter, 2007 Groundwater Report, DUSA will be
required to provide documentation for each RPD calculation used during its review of
analytical reports in a spreadsheet to be included in each groundwater report submitted to the
DRC.
8.0 QA/QC Sample Data Problems - 2"*^ and 3"" quarters of 2009
The following are QA/QC problems that occurred in the monitoring events during the 2"'' and 3"* quarters
of 2009. The issues listed below are in non-compliance with the QAP and details can be found in tables 4
and 5 attached to this memo.
2"" Quarter 2009. Sampling Date: Mav 12 - 30. 2009 (Table 4)
• The field blank (MW-60) had detectable concentrations of zinc, chloroform, carbonate, and
bicarbonate.
• The field blank (MW-60) was also analyzed for nutrients, heavy metals, gross alpha, VOCs, and
inorganics. According to the QAP, DUSA is not required to collect a field blank. However, if
DUSA wants to collect a field blank for in house QA/QC, the DRC has no problem with it as long
as DUSA doesn't use the field blank results to flag or disqualify the groundwater sample results.
June 17. 2009 Accelerated Monitoring Event (Table 4)
• The field blank (MW-60) had detectable concentrations of chloroforrh.
• The field blank (MW-60) was also analyzed for heavy metals, VOCs, and gross alpha. According
to the QAP, DUSA is not required to collect a field blank. However, if DUSA wants to collect a
field blank for in house QA/QC, the DRC has no problem with it as long as they don't use the field
blank results to flag or disqualify the groundwater sample results.
It doesn't appear that DUSA is using the presence of detectable concentrations in the field blanks in 2"
Quarter, 2009 Groundwater Report to flag or disqualify the groundwater sample results. Furthermore, the
approved QAP is currendy silent on how field blanks results should have a bearing on groundwater sample
interpretation.
3'" Quarter 2009. Sampling Date: August 17-31. 2009 (Table 5)
• A trip blank (dated 8/24/2009) showed a result of 21 /ig/L for acetone. Trip blanks are prepared by
the lab and given to the sampler so they can accompany the real samples through transport,
storage, and analysis. Ifa 'hit' is measured in the trip blank and also exists at similar
concentrations in the real samples, the problem is probably somewhere between transport and the
Page 9
completion of analysis. Ifa hit is measured in the trip blank but is not in the real samples, it
usually indicates that the trip blank was not made properly, not stored properly, or not analyzed
properly. There were no other groundwater samples in the 3"* Quarter (August), 2009 monitoring
event that showed detectable concentrations of acetone. Therefore, it appears the source of the
acetone contamination in the trip blank came from the analytical lab. This information was shared
with Ms. Tamara DeMorest ofthe State Health Laboratory in an email dated January 19, 2010.
• Relative Percent Difference was greater than 20% in original sample (MW-22, 0.72 mg/L)
compared to duplicate sample (MW-70, 0.94 mg/L) for Ammonia (as N) (26.51%), see Table 5.
This is in violation of Section 9.1.4(a) ofthe QAP. When DUSA submits an original and duplicate
sample to the DRC for reporting purposes, the DRC will use the sample with the highest
concentration submitted to determine compliance. However, both samples were below the GWCL
for Ammonia (as N) [12.5 mg/L].
• Relative Percent Difference was greater than 20% in original sample (MW-32, 48 mg/L) compared
to duplicate sample (MW-65, 30 mg/L) for chloride (46.15%), see Table 3. This is in violation of
Section 9.1.4(a) ofthe QAP. When DUSA submits an original and duplicate sample to the DRC
for reporting purposes, the DRC will use the sample with the highest concentration submitted to
determine compliance.
September 9. 2009 Accelerated Monitoring Event (Table 5)
• The trip blank (dated 9/9/2009) showed a result of 1.3 /ig/L for chloroform. Trip blanks are
prepared by the lab and given to the sampler so they can accompany the real samples through
transport, storage, and analysis. If a 'hit' is measured in the trip blank and also exists at similar
concentrations in the real samples, the problem is probably somewhere between transport and the
completion of analysis. If a hit is measured in the trip blank but is not in the real samples, it
usually indicates that the trip blank was not made properly, not stored properly, or not analyzed
properly. During the September 2009 monitoring event, monitoring well MW-26 had a chloroform
concentration of 2,800 /ig/L. Therefore, it appears the source of the chloroform seen in the trip
blank came from the cross contamination during sampling. As stated in section 9.1.3 ofthe QAP,
non-conformance is defined when the trip blank samples are within an order of magnitude ofthe
original sample result. The result of 1.3 /ig/L for chloroform in the trip blank is not within an order
of magnitude with the chloroform result (2,800 /ig/L) in monitoring well MW-26. Hence, no QA
flag is needed for this well / parameter.
9.0 Violations Where Pursuing a Notice of Violation is Recommended
I. During the 3"* Quarter (August), 2009 monitoring event, AWAL performed analysis for 19 THF
samples. Although the laboratory is certified by the State of Utah Bureau ofLahoratory
Improvement to perform volatile organics analysis by EPA Method 8260C, it is not certified to
perform testing for THF and Section 8.2 and Table 1 of the DUSA QAP requires that THF be
analyzed under EPA Method 8260B. This is a violation of Section 8.2 and Table 1 ofthe DUSA
QAP and Parts I.E. 1(a) and I.E.5(c) ofthe permit. Separate enforcement action on this matter has
already been taken, see the January 14, 2010 Payment Demand Letter.
10.0 DRC Staff Reconunendations for Enforcement Discretion
1. The 3"* Quarter, 2009 Groundwater Monitoring Report was received by the Division of Radiation
Control (DRC) on December 2, 2009 past its respective due date (December 1). This is a violation
ofPart I.E. lof the Permit.
This is a continuing problem. DUSA was issued a NOV (Docket No. UGWG7-04) on January II,
2008 for failing to provide the T' and 2"'' Quarter 2007 Reports by their due dates (June 1 and
Page 10
September 1, respectively). DUSA was also issued a NOV (Docket No. UGWG8-01) for failing to
provide the 3'^'' Quarter 2007 Report by its respective due date (December 1). However, DRC staff
believes enforcement discretion is.appropriate in this matter, in that, since the 3"* Quarter, 2007
Report and up to the 3'^'' Quarter, 2009 Report, DUSA has provided all groundwater monitoring
reports by their respective due dates. However, if DUSA fails to provide the quarterly
groundwater monitoring reports by their respective due date in the future, the Executive Secretary
will take the appropriate escalated enforcement action.
2. During the 2*"^ Quarter (May), 2009 monitoring event, AWAL performed analysis for 28 THF
samples. Although the laboratory is certified by the State of Utah Bureau ofLahoratory
Improvement to perform volatile organics analysis by EPA Method 8260C, it is not certified to
perform testing for THF and Section 8.2 and Table 1 of the DUSA QAP requires that THF be
analyzed under EPA Method 8260B. This is a violation of Section 8.2 and Table 1 of the DUSA
QAP and Parts I.E. 1(a) and I.E.5(c) of the permit. This problem was brought to DUSA's attention
in the January 14, 2010 Payment Demand Letter.
Although DUSA's analytical laboratory (AWAL) performed analysis for 28 THF samples for the
May 2009 monitoring event under EPA Method 8260C, while Section 8.2 and Table 1 ofthe
DUSA QAP requires that THF be analyzed under EPA Method 8260B, DRC staff believes
enforcement discretion is appropriate in this matter, in that, the problem has already been pursued
via a January 14, 2010 Payment Demand Letter under authority ofthe November 14, 2007
Stipulated Consent Agreement.
3. DUSA failed to evacuate two casing volumes before collecting groundwater samples in 28 wells
during the April - September, 2009 monitoring events. This is in violation of Section 6.2.7(d)(v)
ofthe DUSA QAP and Part I.E. 1(a) ofthe Permit. This is a repeat violation from the T' Qtr, 2009
Report which was brought to the company's attention in a November 17, 2009 NOV (Violation
No. 3). DUSA responded to that action with a December 23, 2009 letter, which is currently in
review.
This is a continuing problem. On November 17, 2009, DUSA was issued a NOV (Docket No.
UGWG9-06) for failing to evacuate two casing volumes before collecting groundwater samples in
13 wells during the January, February, and March 2009 monitoring events. However, DRC staff
believes enforcement discretion is appropriate in this matter, in that, the samples collected in these
wells were collected prior to the December 23, 2009 DUSA commitment that this issue would be
resolved commencing with the 4* Quarter, 2(X)9 Groundwater Monitoring Report. However, if
DUSA fails to evacuate two casing volumes before collecting groundwater samples in any well in
the future, the Executive Secretary will take the appropriate escalated enforcement action.
4. DUSA failed to allow field turbidity to stabilize before collecting groundwater samples in 25 wells
during the April - September, 2009 monitoring events. This is in violation of Section 6.2.7(d)(v)
of the DUSA QAP and Part I.E. 1(a) of the Permit. This is a repeat violation from the P' Qtr, 2009
Report which was brought to the company's attention in a November 17, 2009 NOV (Violation
No. 2). DUSA responded to that action with a December 23, 2009 letter, which is currently in
review.
This is a continuing problem. On November 17, 2009, DUSA was issued a NOV (Docket No.
UGWG9-06) for failing to allow field turbidity to stabilize before collecting groundwater samples
in 17 wells during the Febmary and March 2009 monitoring events. However, DRC staff believes
enforcement discretion is appropriate in this matter, in that, the samples collected in these wells
were collected prior to the December 23, 2009 DUSA commitment that this issue would be
Page 11
resolved commencing with the 4"" Quarter, 2009 Groundwater Monitoring Report. However, if
DUSA fails allow field turbidity to stabilize before collecting groundwater samples in any well in
the future, the Executive Secretary will take the appropriate escalated enforcement action.
11.0 DRC Staff Reconunendations for Improvement
1. During the April - September, 2009 monitoring events, DUSA failed to collect groundwater
samples in several monitoring wells that were below the 5 NTU standard.
Failure to collect groundwater samples below the 5 NTU standard is in violation of Section
6.2.7(d)(v) of the DUSA QAP and Part I.E. 1(a) of the Permit. Unfortunately, the way this
requirement is written in the DUSA QAP "...turbidity measurement in the water should be <5
NTU prior to sampling..." makes it difficult to enforce. The wording ofthis requirement will be
strengthened in the next version ofthe DUSA QAP to make this requirement enforceable. This
recommendation was made previously in a DRC staff memorandum dated July 14, 2009.

Phillip,
Your email was forwarded to me from David Mendenhall regarding THF certification for AWAL. The last instance
of their accreditation for this compound was under RCRA by EPA Method 8260C on 06/04/08. The expiration
date of this letter was 05/31/09. After this date none of the letters that I have in our file show accreditation for
this compound.
I have a RCRA letter right after this date (10/15/08 with the same expiration date of 05/31/09) that does not
show this compound. So they either asked that it be removed or it was inadvertently removed. I'm guessing
they requested the removal since it was never requested by them at a later date to have it removed.
To sum up, they were certified for THF under RCRA by method 8260C through 10/15/08. Please let me Icnow if
you have any additional questions as I am their primary contact in our office. Thank you.
Business hours are Monday-Thursday from 7 a.m. to 6 p.m.

David,
Looking at your databases (RCRA, SDWA, CWA) that you have on your website. It appears AWAL is not
certified for Tetrahydrofuran (THF). Is this correct? I know they were certified for THF in the past. When did
their certification expire?
Thanks in advance.

I don't see THF by 8260 on any previous certificate. A casual review of the certificate letter from their 'primary'
accreditation body did not find it either.
If the lab wants to be Utah certified for this they will need to first have their primary accreditation body accredit
them and then let us know they have added it.
Business hours are Monday - Thursday from 7 a.m. to 6 p.m. and we will beclosed on Fridays.
