HERBERT Govemor GREG BELL Lieutenant Governor Department of Environmental Quality Amanda Smith Executive Director DIVISION OF RADIATION CONTROL Dane L. Finerfrock Director DRC-2010-003910 MEMORANDUM TO: FROM: DATE: SUBJECT: Loren Morton Phil Goble June 23,2010 DUSA's May 24, 2010 response to NOV (Docket Number UGWlO-03) Proposed Civil Penalty Groundwater Discharge Permit (Permit) UG370004 Denison Mines (USA) Corporation (DUSA) White Mesa Mill, Blanding, Utah This is a review of DUSA's May 24, 2010 submitted response to the NOV, Docket Number UGWlO-03. DUSA received the NOV on April 23, 2010 and responded to the DRC on May 24, 2010. No request of a hearing before the BOARD was mentioned within the submittal. This review is based on the criteria outlined under the Order: a) The root cause of the noncompliance, b) Steps that have been or will be taken to correct the violations, c) Date when compliance was or will be regained, and d) Steps taken or to be taken to prevent reoccurrence of the noncompliance. Each DUSA response to these 8 items is in italics below, followed by a DRC finding. VIOLATIONS 1. Violation of Part I.F.I of the Permit for failing to report all well monitoring and samples collected, including a result for TDS in wells MW-31 and MW-32 in the 4"" Quarter 2009 Report, for the October 2009 monitoring event. a) The root cause of the noncompliance: TDS was sampled and analyzed in MW-31 and MW-32 for the 4th quarter of2009, but the samples' for TDS in those wells were received at the laboratory beyond their holding times. TDS was re- sampled in those wells during the 4th quarter 2009 and the sample results were the subject of a separate analytical report. Denver Environmental Staff was not aware of this re-sampling and did not notice the omission of these TDS results when preparing the 4th Quarter 2009 Report, because 168 North 1950 West • Salt Lake City, UT Mailing Address: P.O. Box 144850 • Sah Lake City, UT 84114-4850 Telephone (801) 536-4250 • Fax (801) 533-4097 • T D D. (801) 536-4414 www.deq.uioh.gov Printed on 100% recycled paper Page 2 Denison had not at the time instituted computer checks for completeness on its analytical results. b) Steps that have been or will be taken to correct the violations: The following steps have been taken to correct the violation: (i) When informed by Division of Radiation Control ("DRC) staff of this omission during the week of March 29, 2010, Denison submitted to the Executive Secretary the analytical results for TDS in MW-31 and MW-32 under cover of an email dated April 2. 2010; and (ii) Denison has instituted computer checks for analytical data completeness, commencing with the 1st Quarter 2010 Groundwater Monitoring Report. c) Date when compliance was or will be regained: Compliance was regained on April 2, 2010 with the submission of the analytical results to the Executive Secretary. d) Steps taken or to be taken to prevent reoccurrence of the noncompliance: Denison has instituted computer checks for analytical data completeness, commencing with the 1st Quarter of 2010. DRC Findings: Violation No. 1 still stands, in that the 4* Quarter, 2009 Report failed to include the laboratory results for the compliance sample in question. After considering the Executive Secretary's possible enforcement options, DRC staff believes it is necessary to pursue a penahy for this violation because this is a repeat violation. This same type of reporting problem has occurred multiple times in the last two years, as follows: A. After review of the 1" Quarter, 2008 DUSA Groundwater Monitoring Report, the DRC brought this problem to the company's attention in a July 25, 2008 Notice of Enforcement Discretion (NOED). This episode involved failure to report laboratory results for two monthly sampling events (January and February, 2008) for tetrahydrofiiran in well MW-26. B. Later, this same type of reporting problem was identified after review ofthe 4* Quarter, 2008 Report, and the DRC issued an April 21, 2009 NOV (Docket No. UGW09-04, Violation No. 1), where DUSA was cited: "... for failing to report all well monitoring and sample collected, including a result for TDS in well MW-25 in the 4*^ Quarter, 2008 Report, for the November 2008 monitoring event." Because this problem was a repeat violation, the DRC decided to pursue a Civil Penalty against DUSA. On October 7, 2009 the DRC proposed penalty of $4,815, as part of a Settlement Agreement (SA). The SA was later signed by both parties on November 16, 2009. Payment ofthe $4,815 penalty was received by DRC in a DUSA letter dated October 30, 2009. DUSA responded to the April 21, 2009 NOV in a May 22, 2009 letter, in which they clamed corrective action would start with the 2"'' Quarter, 2009 Groundwater Report. The October 7, 2009 SA was not open- ended, but was instead focused only on Violation No. 1 of the April 21, 2009 NOV. C. This same problem was also identified after review ofthe T' Quarter, 2009 Report, in which DUSA failed to report a result for Thallium in well MW-23 for the February, 2009 monitoring event. The DRC brought this problem to the DUSA's attention in a November 17, 2009 NOED. Page 3 The Executive Secretary chose to use enforcement discretion in this matter, in that, the well MW- 23 Febmary 11, 2009 sample was collected prior to the May 22, 2009 DUSA comiriitment that this issue would be resolved commencing with the 2"** Quarter, 2009 Groundwater Monitoring Report. Because this same problem continues in the 4* Quarter, 2009 Report, in that DUSA failed to report a TDS result in 3 samples (MW-31, MW-32, and MW-65), the DRC staff propose that a new civil penalty be levied against DUSA. This penalty amount has been calculated by DRC staff, which is included later in this memo (see pps. 10 - 20). The DUSA steps to correct the violation (initiation of computer checks for analytical completeness) and to regain compliance (T' Quarter, 2010 report) found in the May 24, 2010 DUSA letter are acceptable. h\ the future, DRC staff will examine the 1" Quarter, 2010 report to verify these DUSA commitments. Violation of Part I.F.I of the Permit and Section 4.3.3 of the DUSA QAP for failing to report all well monitoring and samples collected, including a result for TDS in field duplicate MW-65 in the 4"" Quarter 2009 Report, for the October 2009 monitoring event. a) The root cause of the noncompliance: TDS was sampled and analyzed in field duplicate MW-65 for the 4th quarter of2009. but the sample for TDS was received at the laboratory beyond its holding time. TDS was re-sampled in that well during the 4th quarter 2009 and the results were the subject of a separate analytical report. Denver Environmental Staff was not aware of this re-sampling and did not notice the omission of these TDS results when preparing the 4th Quarter 2009 Report, because Denison had not at the time instituted computer checks for completeness on its analytical results. b) Steps that have been or will be taken to correct the violations: The following steps have been taken to correct the violation: (i) When informed by Division of Radiation Control ("DRC) staff of this omission during the week of March 29, 2010, Denison submitted to the Executive Secretary the analytical resuhs for TDS in MW-65 under cover of an email dated April 2, 2010; and (ii) Denison has instituted computer checks for analytical data completeness, commencing with the 1st Quarter 2010 Groundwater Monitoring Report. c) Date when compliance was or will be regained: Compliance was regained on April 2, 2010 with the submission of the analytical results to the Executive Secretary. I d) Steps taken or to be taken to prevent reoccurrence of the noncompliance: Denison has instituted computer checks for analytical data completeness, commencing with the 1st Quarter of 2010. DRC Findings; Violation No. 2 still stands, in that the 4"" Quarter, 2009 Report failed to include the laboratory results for the compliance sample in question. After considering the Executive Secretary's possible enforcement options, DRC staff believes it is necessary to pursue a penalty for this violation because this is a repeat violation, in that it has occurred multiple times in the last two years, as described below: Page 4 A. This reporting problem is similar to Violation No. 1, above, in that after DRC review of the 1 ^' Quarter, 2008 DUSA Groundwater Monitoring Report it was found that DUSA failed to report laboratory results for two monthly sampling events (January and February, 2008) for tetrahydrofiiran (THF) in well MW-26. In that instance, the problem was brought to the company's attention in a July 25, 2008 NOED. B. This same type of reporting problem was identified after review of the 4* Quarter, 2008 Report, whereafter, the DRC issued an April 21, 2009 NOV (Docket No. UGW09-04, Violation No. 1), where DUSA was cited: "... for failing to report all well monitoring and sample collected, including a result for TDS in well MW-25 in the 4^^ Quarter, 2008 Report, for the November 2008 monitoring event." Again, because this type of problem was a repeat violation, the DRC decided to pursue a Civil Penahy against DUSA of $4,815, as a part of an October 7, 2009 SA. Both parties signed this SA on November 16, 2009. Payment of the $4,815 penalty was received by DRC in a DUSA letter dated October 30, 2009. Further, DUSA responded to the April 21, 2009 NOV in a May 22, 2009 letter, in which they clamed corrective action would start with the 2"'' Quarter, 2009 Groundwater Report. C. This same problem was also identified after review of the 1^' Quarter, 2009 Report, in which DUSA failed to report a result for Thallium in well MW-23 for the February, 2009 monitoring event. The DRC brought this problem to the DUSA's attention in a November 17, 2009 NOED. The Executive Secretary chose to use enforcement discretion in this matter, in that, the well MW- 23 February 11, 2009 sample was collected prior to the May 22, 2009 DUSA commitment that this issue would be resolved commencing with the 2"'' Quarter, 2009 Groundwater Monitoring Report. Because same problem continues in the 4* Quarter, 2009 Report, the DRC staff have proposed a civil penalty be levied against DUSA. Said penalty has been calculated by DRC staff, which is included later in this memo (see pps. 10 - 20). The DUSA steps to correct the violation (initiation of computer checks for analytical completeness) and to regain compliance (T' Quarter, 2010 report) found in the May 24, 2010 DUSA letter are acceptable, hi the ftiture, DRC staff will examine the l" Quarter, 2010 report to verify these DUSA commitments. Violation of Part LE.l(a) ofthe Permit and Section 6.2.7(d)(v) ofthe DUSA QAP for failing to achieve stable turbidity conditions before collecting groundwater samples in 12 wells during the October, November, and December, 2009 monitoring events. a) The root cause of the noncompliance: Data indicate that it may not be feasible to achieve both a turbidity level less than 5 NTU and a stabilized turbidity between any tnv measurements within 10% RPD in every well. Discussions are underway with DRC to address the issue that it may not be appropriate or feasible to achieve consistent turbidity levels 3 of 5 NTU in the Mill's groundwater program wells under the current evacuation scheme, and that other well purging approaches, such as micro-purging, may be more appropriate. b) Steps that have been or will be taken to correct the violations: A letter report addressing modification of monitoring methods relative to turbidity issues, submitted by DUSA to DRC is currently under review. c) Date when compliance was or will be regained: Page 5 Compliance will be achieved when monitoring methods relative to turbidity are modified to address Mill site conditions. d) Steps taken or to be taken to prevent reoccurrence of the noncompliance: See paragraph c) above. DRC Findings: Violation No. 3 still stands, in that the 4* Quarter, 2009 Report failed to achieve stable turbidity conditions before collecting groundwater samples in 12 wells during the October, November, and December, 2009 monitoring events. After considering the Executive Secretary's possible enforcement options, DRC staff believes it is necessary to pursue a penalty for this violation because this is a repeat violation, as follows: After DRC review ofthe DUSA T' Quarter, 2009 Ground Water Monitoring Report, DUSA was cited for several groundwater sampling / monitoring problems in a November 17, 2009 NOV (Docket No. UGW09-06). hi Violation No. 2 of this NOV, DUSA was cited: "... for failing to achieve stable turbidity conditions before collecting groundwater samples in 17 wells during the February and March, 2009 monitoring events." DUSA responded to that NOV with a December 23, 2009 leUer in which they, in part explained that corrective actions included retraining of their sampling staff regarding current QAP requirements for stable field parameters, including turbidity, before sample collection. In addition, DUSA stated that compliance had been regained, in that "Samples were collected in accordance with Sections 6.2.7(d)(v) and 6.2.7(d)(vi) of the QAP during the 4"' Quarter, 2009 event. " Apparently, this commitment by DUSA was not lasting; therefore, a proposed civil penalty has been calculated by DRC staff, which is included later in this memo (see pps. 10 - 20), The DUSA steps to correct the violation (submittal of April 2, 2010 request for waiver) and to regain compliance (when monitoring methods relative to turbidity are modified to address Mill site conditions) found in the May 24, 2010 DUSA letter are unacceptable. The April 2, 2010 request for waiver does not constitute an acceptable corrective action, nor does it provide prevention steps that DUSA was ordered to provide in the April 20, 2010 NOV. Therefore, Violation No. 3 remains unresolved, and DUSA has yet to re-gain compliance with respect to this violation. Violation of Part I.E.l(a) ofthe Permit and Section 6.2.7(d)(v) ofthe DUSA QAP for failing to achieve stable redox potential (Eh) conditions before collecting groundwater samples in 5 wells during the October and November, 2009 monitoring events. a) The root cause of the noncompliance: The calculations used by Denver Environmental Staff were incorrect, and, as a result the failures to achieve stable redox potential conditions were not apparent when preparing the 4th Quarter 2009 Groundwater Monitoring Report. The calculation has been computer automated, verified and corrected as of the 1st Quarter 2010 Groundwater Monitoring Report. With respect to the actual failure to achieve stable redox potential in the wells, data indicate that it may not be feasible to achieve stabilized parameters, including redox, between any two measurements within 10% RPD in every well. Discussions are underway with DRC to address the issue that it may not be appropriate or feasible to achieve stabilization of every parameter in every Page 6 well under the current evacuation scheme, and that other well purging approaches, such as micro- purging, may be more appropriate. b) Steps that have been or will be taken to correct the violations: A letter report addressing modification of monitoring methods relative to parameter stability issues, submitted by DUSA to DRC is currently under review. c) Date when compliance was or will be regained: Compliance will be achieved when monitoring methods relative to turbidity are modified to address Mill site conditions. d) Steps taken or to be taken to prevent reoccurrence of the noncompliance: See paragraphs a) and c) above. DRC Findings: Violation No. 4 still stands, in that the 4* Quarter, 2009 Report failed to achieve stable redox potential (Eh) conditions before collecting groundwater samples in 5 wells during the October and November, 2009 monitoring events. After considering the Executive Secretary's possible enforcement options, DRC staff believes it is necessary to pursue a penalty for this violation because it is a field parameter that must be stable before sample collection, and is therefore related to Violation No. 3, above. For this reason. Violations 3 and 4 have been combined into one civil penalty amount, see proposed civil penalty calculated by DRC staff, which is included later in this memo (see pps. 10 - 20). The DUSA steps to correct the violation (submittal of April 2, 2010 request for waiver) and to regain compliance (when monitoring methods are modified to address Mill site conditions) found in the May 24, 2010 DUSA letter are unacceptable. The April 2, 2010 request for waiver does not constitute an acceptable corrective action, nor does it provide prevention steps that DUSA was ordered to provide in the April 20, 2010 NOV. Therefore, Violation No. 4 remains unresolved, and DUSA has yet to re-gain compliance with respect to this violation. Violation of Part I.E. 1(a) of the Permit and Section 6.2.7(d)(v) of the DUSA QAP for failing to excavate two casing volumes before collecting groundwater samples in 17 wells during the 4"" Quarter (October) 2009 monitoring event. a) The root cause of the noncompliance: As stated in the 4th Quarter 2009 Groundwater Monitoring Report, prior to November 17, 2009, sampling personnel believed that they had the option either to pump each well to two casing volumes or to pump the well until field parameters were stabilized. Further, they believed they had the verbal approval of the DRC representative who has witnessed the field sampling program, to determine how long each well would require to be pumped to two casing volumes, and to pump only to 120 minutes on any well that would require longer than this interval of time. DUSA received a Notice of Violation dated November 17, 2009 in which DRC identified that Mill staff were not following the QAP requirement to evacuate two casing volumes and to achieve stable parameters. b) Steps that have been or will be taken to correct the violations: Page 7 As stated in the 4th Quarter 2009 Groundwater Monitoring Report, on receipt of the November 17, 2009 NOV, sampling personnel were instructed to evacuate two casing volumes and determine well parameter stabilization. They were also instructed that a perceived verbal approval from DRC personnel will not replace the written requirements of the Permit and/or the QAP. c) Date when compliance was or will be regained: As stated in the 4th Quarter 2009 Groundwater Monitoring Report, the first two months of the 4th Quarter 2009 sampling program were already under way at the time sampling personnel received these instructions. As a result the October and November 2009 samples were collected under an incorrect understanding of the procedure. d) Steps taken or to be taken to prevent reoccurrence of the noncompliance: See paragraph b) above. DRC Findings: Violation No. 5 still stands, in that the 4* Quarter, 2009 Report failed to evacuate two casing volumes before collecting groundwater samples in 17 wells during the 4* Quarter (October) 2009 monitoring event. After considering the Executive Secretary's possible enforcement options, DRC staff believes it is necessary to pursue a penalty for this violation because this is a repeat violation. Previously, in a November 17, 2009 NOV (Violation No. 3), DUSA was cited: "... for failing to excavate (sic) two casing volumes before collecting groundwater samples in 13 wells during the January, February, and March 2009 monitoring events." DUSA responded to that NOV with a December 23, 2009 letter, in which they in part explained that corrective actions included re-training of their sampling staff regarding current QAP requirements for stable field parameters, including Eh, before sample collection. In addition, DUSA stated that compliance had been regained in that the "Samples were collected in accordance with Sections 6.2.7(d)(v) and 6.2.7(d)(vi) of the QAP during the 4"' Quarter, 2009 event. " Apparently, this commitment by DUSA was not lasting; therefore, a proposed civil penalty has been calculated by DRC staff, which is included later in this memo (see pps. 10 - 20). The DUSA steps to correct the violation (sampling personnel instructed to purge for two casing volumes) and to regain compliance (T' Quarter, 2010 report) found in the May 24, 2010 DUSA letter are acceptable, hi the ftiture, DRC staff will examine the T' Quarter, 2010 report to verify these DUSA commitments. Violation of Part I.E. 1(a) ofthe Permit and Section 3.1 ofthe DUSA QAP for failing to use the correct formula in 39 instances to determine RPD for the duplicates of the October, November, and December, 2009 monitoring events. a) The root cause of the noncompliance: The RPD calculation results in the 4th Quarter 2009 and previous groundwater and chloroform reports have been in error, as brought to the attention of DUSA by DRC in their letter of February 17, 2010 and close out telephone call of April 5, 2010. b) Steps that have been or will be taken to correct the violations: The RPD calculation has been computer automated, verified and corrected as of the 1st Quarter 2010 Groundwater Monitoring Report. Page 8 c) Date when compliance was or will be regained: Compliance has been achieved as of May 19, 2010, the date offiling the 1st Quarter 2010 Groundwater Monitoring Report. d) Steps taken or to be taken to prevent reoccurrence of the noncompliance: See paragraph b) above. DRC Findings; Violation No. 6 still stands, because DUSA failed to use the correct formula in 39 instances to determine Relative Percent Difference (RPD) for the duplicate samples collected during the October, November, and December, 2009 monitoring events. After considering the Executive Secretary's possible enforcement options, the DRC staff recommends no penalty at this time on the basis that this was the first time this problem has been cited. However, should these violations be repeated in the fiiture a penalty may be assessed. The DUSA steps to correct the violation (computer automation of the RPD formula) and to regain compliance (T' Quarter, 2010 report) are acceptable. In the future, DRC staff will examine the T' Quarter, 2010 report to verify these DUSA commitments. 7. Violation of Part I.F.l(e) of the Permit and Section 9.1.4(a) of the DUSA QAP for failure to fully and completely disclose all non-conformance with the approved QAP for the October, 2009 sampling event with respect to a RPD in excess of 20"/o for ammonia (as nitrogen) in well MW-22 and blind duplicate sample MW-70. a) The root cause of the noncompliance: As a result of DUSA using the incorrect manner of calculating RPD referred to in Violation 6 above, the RPD in excess of 20%) for ammonia (as nitrogen) in well MW-22 and blind duplicate sample MW- 70 was not apparent, and therefore not disclosed. b) Steps that have been or will be taken to correct the violations: The RPD calculation has been computer automated, verified and corrected as of the 1st Quarter 2010 Groundwater Monitoring Report, so that this type of violation will not occur in. the future^. c) Date when compliance was or will be regained: Compliance has been achieved as of May 19, 2010, the date offiling the 1st Quarter 2010 Groundwater Monitoring Report. d) Steps taken or to be taken to prevent reoccurrence of the noncompliance: See paragraph b) above. DRC Findings; Violation No. 7 still stands, because DUSA failed to fully and completely disclose non-conformance in well MW-22 and blind duplicate sample MW-70 for the October, 2009 sampling event, where the RPD for ammonia (as nitrogen) was greater than 20%. After considering the Executive Secretary's possible enforcement options, the DRC staff recommends no penalty at this time on the basis that this was the Page 9 first time this problem has been cited. However, should these violations be repeated in the fiiture a penalty may be assessed. The DUSA steps to correct the violation (computer automation ofthe RPD formula) and to regain compliance (1^' Quarter, 2010 report) are acceptable. In the future, DRC staff will examine the 1^' Quarter, 2010 report to verify these DUSA commitments. 8. Violation of Part I.E. 1(a) of the Permit and Section 11 of the DUSA QAP for failing to list in a summary table analytes wells that were subject to accelerated monitoring pursuant to Parts I.G.I and 2 ofthe Permit, including uranium (MW-14, MW-15, and MW-17) and thallium (MW- 18). a) The root cause of the noncompliance: Denver Environmental Staff inadvertently omitted these analytes from the summary table of analytes that are subject to accelerated monitoring. When preparing the 4th Quarter 2009 Report, Denison had not at the time instituted computer checks for determining accelerated monitoring status. b) Steps that have been or will be taken to correct the violations: Denison has instituted computer checks for determining accelerated monitoring status for analytes, commencing with the 1st Quarter 2010 Groundwater Monitoring Report. c) Date when compliance was or will be regained: Compliance was regained on May 19, 2010 with the filing of the 1st Quarter 2010 Groundwater Monitoring Report. d) Steps taken or to be taken to prevent reoccurrence of the noncompliance: Denison has instituted computer checks for determining accelerated monitoring status, commencing with the 1st Quarter of 2010. DRC Findings; Violation No. 8 still stands, because DUSA failed to list all monitoring wells and analytes subject to accelerated groundwater monitoring under Parts I.G.I or I.G.2 of the Permit, including GWCL exceedances from the October, 2009 sampling event for uranium in three wells (MW-14, MW-15, and MW-17) and thallium in well MW-18. After considering the Executive Secretary's possible enforcement options, the DRC staff recommends no penalty at this time on the basis that this was the first time this problem has been cited. However, should these violations be repeated in the future a penalty may be assessed. The DUSA steps to correct the violation (computer automation for checks on accelerated monitoring status) and to regain compliance (T' Quarter, 2010 report) are acceptable. In the ftiture, DRC staff will examine the T' Quarter, 2010 report to verify these DUSA commitments. Of the eight violations described above, DRC staff believes it is appropriate to seek a civil penalty for five of the eight violations, this is described in detail below: Page 10 WATER OUALITY PENALTY CRITERIA According to R3I7-1-8 (Penalty Criteria for Civil Settlement Negotiations), the penalty calculation methodology consists of the following formula: CIVIL PENALTY = PENALTY + ADJUSTMENTS - ECONOMIC AND LEGAL CONSIDERATIONS I. Category Selection (R317-1-8.3) Table 1 below describes the Water Quality penalty categories. TABLE 1 Water Quality Penalty Categories (UAC R317-1-8.3) Category A - $7,000 to $10,000 per day. Violations with high impact on public health and the environment to include: Category A.l - Discharges which result in documented public health effects and/or significant environmental damage. Category A.2 - Any type of violation not mentioned above severe enough to warrant a penalty assessment under category A. • Category B - $2,000 to $7,000 per day. Major violations of the Utah Water Pollution Control Act, associated regulations, permits or orders to include: Category B.l - Discharges which likely caused or would potentially cause (undocumented) public health effects or significant environmental damage. Category B.2 - Creation of a serious hazard to public health or the environment. Category B.S - Illegal discharges containing significant quantities of concentrations of toxic or hazardous materials. Category B.4 - Any type of violation not mentioned previously which warrants a penalty assessment under category B. Category C - $500 to $2,000 per day. Violations ofthe Utah Water Pollution Control Act, associated regulafions, permits or orders to include: Category C.l - Significant excursion of permit effluent limits. Category C.2 - Substantial non-compliance with the requirements of a compliance schedule. Category C.3 - Substantial non-compliance with monitoring and reporting requirements. Category C.4 - Illegal discharge containing significant or concentrafions of non toxic or non hazardous materials. Category C.5 - Any type of violafion not menfioned previously which warrants a penalty assessment under category C. Category D - up to $500 per day. Minor violations of the Utah Water Pollution Control Act, associated regulations, pennits or orders to include: Category D.l - Minor excursion of permit effluent limits. Category D.2 - Minor violafions of compliance schedule requirements. Category D.3 - Minor violations of reporting requirements. Category D.4 - Illegal discharges not covered in Categories A, B and C. Category D.5 - Any type of violations not mentioned previously which warrants a penalty assessment under category D. After reviewing the 4"" Quarter, 2009 Groundwater Monitoring Report, the DRC cited DUSA for eight violations, five of which deserve monetary penalties; however, none of the violafions caused Page 11 direct or potential harm to human health and the environment (Category A and B); nor were there violations relevant to Category C. Therefore, the following penalty categories do not apply: Categories A, B, C and D. 1,2, and 4. Some ofthe eight violations that qualify for monetary penaUies fall under the penalty Category D.3 (Violations 1 - 2) and the others fall under Category D.5 (Violations 3 - 5). For details see Table 1 above. The violations described above that are similar in nature were combined into three (3) separate civil penalties. This is summarized in the table below: Violations Penalties Why Combined 1 - Failure to submit TDS results for well MW-31 and MW-32 Penalty I DUSA failed to submit TDS results for both violations 2 - Failure to submit a TDS result for sample MW-65 Penalty I DUSA failed to submit TDS results for both violations 3- Failure to achieve stable parameters (turbidity) before sample collection Penalty 2 DUSA failed to achieve stable parameters before sample collections for both violations, turbidity and redox potential (EH) are both field parameters 4- Failure to achieve stable parameters [redox potential (EH)] before sample collection Penalty 2 DUSA failed to achieve stable parameters before sample collections for both violations, turbidity and redox potential (EH) are both field parameters 5- Failure to purge for 2 casing volumes before sample collection Penalty 3 NA 1. Penalty 1: Violations 1 and 2 - including failure to report all well monitoring and samples collected, including a result for TDS in wells MW-31, MW-32 (Violation 1) and sample MW-65 (Violation 2) in the 4"' Quarter 2009 Report, for the October 2009 monitoring event. STATUTORY MAXIMUM PENALTY The number of days that DUSA is considered to be out of compliance was calculated from the date the 4"^ Quarter, 2009 Groundwater Monitoring Report was due (March 1, 2010) to the day DUSA submitted the analytical report (by e-mail) for TDS in wells MW-31, MW-32, and field duplicate MW-65 (April 2, 2010) for a total of 33 days. This approach to the number of days of violation is consistent with that taken by the DRC in resolution of the April 21, 2009 NOV (see DRC memorandum dated September 29, 2009). The proposed maximum penalty, therefore, would be calculated for 33 days at $500 per day is $16,500. ASSIGNED PENALTY AMOUNT WITHIN A CATEGORY History of compliance or non-compliance: Page 12 Under UAC R317-1-8.3(A), two factors need to be considered, including previous violations and degree of recidivism. DRC Findings: According to DRC records, DUSA has been out of compliance with the reporting requirements of Part I.F.I of the Permit in two different quarterly monitoring reports in 2008 (l" Qtr, 2008 and 4"" Qtr, 2008) and two different quarteriy monitoring reports in 2009 (1'' Qtr, 2009 and 4* Qtr, 2009) for a total of four times. The original Ground Water Discharge Permit was issued to DUSA in March, 2005, and submission of quarterly groundwater quality reports began in June, 2005 (1^' Quarter, 2005). Since that time, DUSA has submitted 20 quarterly groundwater quality reports up thru 4* Quarter, 2009. As a result, 4 of 20 reports were found to have the same type of problem cited, or 20% of the total. In contrast, 80% of the reports submitted have not been found with this problem. However, the DRC staff recommends that only a 50% credit be given for history of compliance due to the following factors: 1. Incomplete reports have been a continuing problem as shown by the multiple formal enforcement actions taken to date (2 NOEDs and 1 NOV), see Items 1 and 2 above, 2. A monetary penalty for this same problem, was pursued for the 4^^ Quarter, 2008 DUSA Report via an October 7, 2009 ($4,815) Settiement Agreement. DUSA paid this penalty amount on October 30, 2009), 3. In May 22, 2009 response to the April 21, 2009 NOV, DUSA made a commitment to correct the reporting problem starting with the 2"^* Quarter, 2009 report. DUSA then failed to follow thru on said commitment. 4. During resolution ofthe April 21, 2009 NOV, the DRC provided 87% credit for history of non-compliance (see DRC memorandum dated September 29, 2009). 5. Today, this history has degraded, and a smaller degree of credit is warranted. B. Degree of willfulness and/or negligence: Four factors need to be considered under the requirements of UAC R317-1-8.3(B), including: 1. How much control the violator had over and the foreseeability of the events constituting the violation; 2. Whether the violator made or could have made reasonable efforts to prevent the violation; 3. Whether the violator knew of the legal requirements which were violated; 4. Degree of recalcitrance. DRC finds that: • DUSA had control over the events constituting the violation, i.e., report preparation. Further, DUSA is ultimately responsible for submitting all analytical results for the groundwater samples required by the Permit. Page 13 • DUSA could have made a reasonable effort to carefiilly review the analytical data, and identify the missing information in the analytical report thus preventing the violation. • DUSA knew of the legal/Permit/QAP requirements which were specifically listed in two different sections of the Permit, including: Part I.E. 1(d)(2) that requires analysis of all GWPL parameters in Table 2 of the Pennit, and Part I.F.I ofthe Permit, that requires reporting of all sample and analytical results required under the Permit. Further, both of these requirements have existed in the Permit since the original March, 2005 Permit. • To DRC knowledge, there is no indication of any recalcitrance. The DRC doesn't believe DUSA intentionally withheld TDS results for wells MW-31 and MW-32 and sample MW-65 for the 4"^ Quarter (October) 2008 monitoring event, but it does appear they were negligent in report preparation. At a minimum, it appears that DUSA negligence was present in report preparation, in that this is the 4"^ time since the 1^' Quarter of 2008 that DUSA has been cited for this problem. During resolution of the April 21, 2009 NOV, the DRC provided 50% credit for willfulness / negligence (see DRC memorandum dated September 29, 2009). Today, the record shows an increased degree of negligence. Hence, a smaller degree of credit is warranted. Accordingly, the DRC will assign a 25% credit for this category. C. Good faith efforts to comply: Under UAC R317-1-8.3(C), this includes the Permittee's openness in dealing with the violations, promptness in correction of problems, and degree of cooperation with the State. DUSA was prompt and cooperative, in that after being verbally notified of the missing TDS results in a phone call of March 29, 2010, DUSA emailed the missing laboratory results to DRC staff on April 2, 2010. However during-resolution of the April 21, 2009 NOV, the DRC provided 100% credit for good faith efforts to comply (see DRC memorandum dated September 29, 2009). Today, the record shows a decreased degree of good faith, in that problems were not corrected, but instead repeated; despite DUSA commitments to the contrary. Hence, a smaller degree of credit is warranted today. Therefore, a credit of 50% was given for good faith efforts to comply in a timely manner. Penalty Calculation Category D, which is a maximum of $500 per day penalty = $500 Credits: 1/3 (max $166) History of Compliance: (50% credit) =$83 1 /3 (max $ 166) Degree of Willftilness and/or Negligence: (25% credit) = $42 1 /3 (max $ 166) Good Faith Efforts to Comply: " (50% credit) = $83 Total credit = $208 Penalty per day violation: = $292 Number of days of violation: = 33 Total Category Penalty (Gravity Component) = $9,636 ADJUSTMENTS Page 14 According to R317-1-8.3, the civil penalty shall be calculated by adding the following adjustments to the penalty amount determined above: a. Economic benefit (Cost Avoided) gained as a result of non-compliance. DUSA did not gain any economic benefit by not the submitting the TDS results for wells MW-31 and MW-32 and sample MW-65 for the 4"^ Quarter (October) 2009 monitoring event. DUSA had paid for the analysis to be done; however, the results were not submitted with the 4* Quarter, 2009 Groundwater Monitoring Report. Therefore, no economic benefit will be considered with this proposed civil penalty. b. Investigatiye costs incurred by the DRC and/or other govemmental levels: Based on the degree of the violation (Category D.3), investigative costs incurred by governmental agencies are not included. Proposed Civil Penalty for Docket No. UGWl0-03 (Violations 1-2): $ 9,636 2. Penalty 2: Violations 3 and 4 - including failure to achieve stable turbidity conditions before collecting groundwater samples in 12 wells (Violation 3) and stable redox potential (Eh) conditions (Violation 4) before collecting groundwater samples in 5 wells for a total of 14 wells (aggregate) during in the 4"' Quarter 2009 Report, for the October, November, and December 2009 monitoring events. STATUTORY MAXIMUM PENALTY The number of days that DUSA is considered to be in out of compliance was based on each day of sampling for each sampling in the 4"^ Quarter, 2009, where field parameters did not stabilize within 10% over at least two consecutive measurements: October (7 days)', November (1 day)^, and December (1 day)^ for a total of 9 days. This approach to the number of days of violation is consistent with that taken by the DRC in resolution ofthe April 21, 2009 NOV (see DRC memorandum dated September 29, 2009). The proposed maximum penalty, therefore, would be calculated for 9 days at $500 per day is $4,500. ASSIGNED PENALTY AMOUNT WITHIN A CATEGORY A. History of compliance or non-compliance: Under UAC R317-1-8.3(A), two factors need to be considered, including previous violations and degree of recidivism. ' DUSA 4* Quarter, 2009 Report, dated March 1, 2010 (Tab B) to the November 17, 2009 NOV, shows: 1) the DUSA "quarterly" sampling event was conducted during the month of October, and 2) the November and December, 2009 DUSA monitoring events were related to accelerated sampling. Further, in the December 23, 2009 DUSA response letter (p. 3), the company claims that compliance has been regained, in that sampling conformed with the applicable Ground Water Quality Assurance Plan requirements "... during the 4"" Quarter, 2009 event." The DUSA October, 2009 sampling event was conducted October 12 - 28, 2009. ^ The DUSA November and December sampling events were conducted on November 1-3, 2009 and December 1 - 3, 2009 (see 3/1/10 DUSA Report, Tab C and Tab D). Page 15 DRC Finding: According to DRC records, DUSA has been out of compliance with the purging requirements of Part I.E. 1 (a) of the Permit and Section 6.2.7(d)(v) of the DUSA QAP in every quarter since routine groundwater monitoring began. However, DUSA was not cited for these problems until after review of the 1^' Quarter, 2009 GW Report (November 17, 2009 DRC NOV) because they hadn't been identified by DRC staff until then. Therefore, 50% credit was given for history of compliance after consideration that the previous purging problems were not cited. B. Degree of willfulness and/or negligence: Four factors need to be considered under the requirements of UAC R317-1 - 8.3 (B), including: 1. How much control the violator had over and the foreseeability of the events constituting the violation; 2. Whether the violator made or could have made reasonable efforts to prevent the violation; 3. Whether the violator knew of the legal requirements which were violated; 4. Degree of recalcitrance. DRC finds that: • DUSA had control over the events constituting the violation, i.e., DUSA sampling staff conducts groundwater sampling and should have followed existing QAP requirements and allowed field parameters to stabilize within 10% over at least two consecutive measurements prior to sarhple collection. • DUSA could have made a reasonable effort to follow Part I.E. 1(a) of the Permit and Section 6.2.7(d)(v) of the DUSA QAP by allowing field parameters to stabilize within 10% over at least two consecutive measurements prior to sample collection. • DUSA knew of the legal/Permit/QAP requirements which were specifically listed in the DUSA QAP and Pennit, including: Section 6.2.7(d)(v) ofthe DUSA QAP, that requires field parameters to stabilize within 10% over at least two consecutive measurements prior to sample collection, and Part I.E. 1(a) of the Permit, that requires all groundwater monitoring and analysis performed under the Permit shall be conducted in accordance with the DUSA QAP. These requirements have existed in the Permit since the November 28, 2006, Permit (Mod.4) and since the original November 17, 2006 DUSA QAP, approved by the DRC on December I, 2006. • To the best of DRC knowledge, there is no indication of any recalcitrance and DUSA wasn't aware of this problem until it was first cited after end of the first quarter in 2009, see November 17, 2009 NOV and Order 09-06 (4'*' Quarter, 2008 Monitoring Report). Therefore, a 25% credit should be given for this category. C. Good faith efforts to comply: Under UAC R317-1-8.3(C), this includes the Permittee's openness in dealing with the violations, promptness in conection of problems, and degree of cooperation with the State. Page 16 This problem of unstable field parameters at the time of sample collection was also found in the I^' Quarter, 2009 DUSA groundwater monitoring report (see November 17, 2009 NOV, Violation No. 2). DUSA responded to that action with a December 23, 2009 letter, in which they stated that compliance had already been achieved because , the "Samples were collected in accordance with Sections 6.2.7(d)(v) and 6.2.7(d)(vi} of the QAP during the 4"' Quarter, 2009 event. " The 4"^ Quarter, 2009 Report showed that this problem was not corrected, but instead repeated (despite DUSA commitments to comply during the 4* Quarter, 2009 sampling event). The DRC notified DUSA of this problem on March 29, 2010 in a closeout meeting. DUSA submitted a Request for Variance for Turbidity on April 2, 2010. The DUSA proposed steps to correct the problem (submittal of April 2, 2010 letter in the May 24, 2010 letter were found to be unacceptable. The April 2, 2010 request for waiver does not constitute an acceptable conective action, nor did it provide prevention steps that DUSA was ordered to provide in the April 20, 2010 NOV. Compliance can not be based on what the DRC might or might not do in the fiiture. It appears that DUSA is not accepting responsibility for the turbidity problem; therefore, a 25% credit should be given for this category. Penalty Calculation Category D, which is a maximum of $500 per day penalty = $500 Credits: 1/3 (max $166) History of Compliance: (50% credit) =$83 1/3 (max $166) Degree of Willftilness and/or Negligence: (25% credit) = $42 1/3 (max $166) Good Faith Efforts to Comply: (25% credit) = $42 Total credit = $167 Penalty per day violation: = $333 Number of days of violation: = 9 Total Category Penalty (Gravity Component) = $2,997 ADJUSTMENTS According to R317-1-8.3, the civil penalty shall be calculated by adding the following adjustments to the penalty amount determined above: a. Economic benefit (Cost Avoided) gained as a result of non-compliance: Section 6.2.7(d)(v) of the DUSA QAP states: "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. " DUSA failed to allow field parameters to stabilize prior to sample collection in 14 wells (aggregate) prior to sample collection in the 4* Quarter (October), 2009 monitoring event. DUSA should have continued purging until stable parameters had been established. DRC Staff believes that DUSA saved money by failing to purge until stable parameters had been reached. However, it is difficult to quantify because there is no set time when stable parameters will be reached. DUSA purged for two casing volumes in all wells for the November and December, 2009 Page 17 monitoring events and still didn't obtain stable parameters; therefore, because of this difficulty, no economic benefit will be considered with this proposed civil penalty. b. Investigative costs incurred by the DRC and/or other govemmental levels: Based on the degree of the violation (Category D.5), investigative costs incurred by govemmental agencies are not included. Proposed Civil Penalty for Docket No. UGWlO-03 (Violations 3-4): $ 2,997 3. Penalty 3: Violation 5 - for failure to excavate two casing volumes before collecting groundwater samples in 17 wells during the 4"" Quarter 2009 Report, for the October 2009 monitoring event. STATUTORY MAXIMUM PENALTY The number of days that DUSA is considered to be in out of compliance was based on each day of sampling where DUSA failed to purge two casing volumes before sample collection in the 4"^ Quarter (October), 2009 monitoring event, including October 12 - 14, 19-21, and 26 - 27, for a total of 8 days. This is consistent with the basis for the maximum number of days determined before for this same problem during resolution of the November 17, 2009 NOV (1^' Quarter, 2009 Report). The proposed maximum penalty, therefore, would be calculated for 8 days at $500 per day is $4,000 ASSIGNED PENALTY AMOUNT WITHIN A CATEGORY A. History of compliance or non-compliance: Under UAC R317-1-8.3(A), two factors need to be considered, including previous violations and degree of recidivism. DRC Finding: According to DRC records, DUSA has been out of compliance with the purging requirements of Part I.E.I (a) of the Permit and Section 6.2.7(d)(v) of the DUSA QAP in every quarter since routine groundwater monitoring began. However, DUSA was not cited for these problems until the l" Quarter, 2009 GW Report (November 17, 2009 NOV, Violation No. 3), because they hadn't been identified by DRC staff until then. Because this problem was cited previously, DRC staff believes a 50% credit is appropriate for history of compliance after consideration that the previous purging problems were not cited. B. Degree of willfulness and/or negligence: Four factors need to be considered under the requirements of UAC R317-1-8.3(B), including: 1. How much control the violator had over and the foreseeability of the events constituting the violation; 2. Whether the violator made or could have made reasonable efforts to prevent the violation; Page 18 3. Whether the violator knew of the legal requirements which were violated; 4. Degree of recalcitrance. DRC finds that: • DUSA had control over the events constituting the violation, i.e., DUSA sampling staff conducts groundwater sampling and should have purged for two casing volumes before sample collection. • DUSA could have made a reasonable effort to follow Part I.E.I (a) of the Permit and Section 6.2.7(d)(v) of the DUSA QAP by purging for two casing volumes before sample collection. • DUSA knew of the legal/Permif QAP requirements which were specifically listed in the DUSA QAP and Pennit, including: Section 6.2.7(d)(v) ofthe DUSA QAP, that requires purging be performed until two casing are removed prior to sample collection, and Part I.E.1(a) of the Permit, that requires all groundwater monitoring and analysis performed under the Pennit shall be conducted in accordance with the DUSA QAP. These requirements have existed in the Pennit since the November 28, 2006, Pennit (Mod.4) and since the original November 17, 2006 DUSA QAP. Further, this requirement was brought to DUSA's attention in the November 17, 2009 DRC NOV (Violation 3). • To the best of DRC knowledge, there is no indication of any recalcitrance and DUSA wasn't aware of this problem until it was first cited in the April 21, 2009 NOV and Order 09-06 (l" Quarter, 2009 Monitoring Report). Therefore, a 25% credit should be given for this category. C. Good faith efforts to comply; Under UAC R317-1-8.3(C), this includes the Permittee's openness in dealing with the violations, promptness in correction of problems, and degree of cooperation with the State. DRC Finding: This problem was also found in the 1'* Quarter, 2009 DUSA groundwater monitoring report, and 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, in which they claimed that compliance had already been regained, in that the "Samples were collected in accordance with Sections 6.2.7(d)(v) and 6.2.7(d)(vi) of the QAP during the 4^ Quarter, 2009 event. " The 4^*^ Quarter, 2009 Report showed that this problem was not conected, but instead repeated (despite the December 23, 2009 DUSA statements that compliance had already been regained). Also, it is clear that the previous DUSA commitment was not lasting; therefore, a 50% credit should be given for this category. Penalty Calculation Category D, which is a maximum of $500 per day penalty = $500 Credits: 1/3 (max $166) History of Compliance: (50% credit) =$83 1/3 (max $166) Degree of Willfiilness and/or Negligence: (25% credit) = $42 1 /3 (max $ 166) Good Faith Efforts to Comply: (50% credit) = $83 Total credit = $208 Page 19 Penalty per day violation: Number of days of violation: Total Category Penalty (Gravity Component) = $292 = 8 = $2,336 ADJUSTMENTS According to R317-1-8.3, the civil penalty shall be calculated by adding the following adjustments to the penalty amount determined above: a.
