Re: Rock Creek Mine, Background Baseline Ground Water Quality Statistics

Project #: 114-31979

AGC’s groundwater monitoring plan was developed to determine whether TSF seepage, if any, or the groundwater injection well field (IWF) contribute to a significant increase in constituent of concern (COC) concentrations or an exceedance of applicable Alaska water quality standards for drinking water. Representative monitoring wells have been established at 4 locations down gradient of the TSF (MW06-08A, MW06-09A/B and MW06-10A) and 2 locations downgradient of the IWF (MW07-11 and MW08-15A) (

Background

Figure 1). Samples are collected monthly from the TSF monitoring wells and quarterly from the IWF monitoring well.

Under the February 20, 2009 temporary closure plan (TCP) for the Rock Creek Mine, AGC is required to monitor groundwater to demonstrate compliance with limits based on Alaska water quality standards. In addition, TCP Table D3 establishes action levels for specific constituents in the monitoring wells downgradient of the TSF. These trigger values were based on an initial assessment of background levels and are intended to assess whether TSF seepage is reaching the monitoring wells. The TCP did not establish action levels for the IWF monitoring well.

Compliance Summary

Table 1 shows the total number of exceedances observed for both Alaska water quality standards and TCP action levels during 2009 in the TSF monitoring wells. Table 2 shows the number of exceedances observed in the IWF monitoring wells. Waste Management Permit Conditions 1.2.10 and 1.10.3 require AGC to submit a plan to ADEC outlining proposed corrective actions to prevent adverse environmental impacts and prevent further exceedances.

Measures outlined below constitute AGC’s proposed corrective action plan as required by Waste Management Permit Condition 1.10.3. Upon approval by ADEC, AGC will commence implementing this proposed corrective action plan. Based upon the analysis prepared by Tetra Tech enclosed as Attachment 1, AGC concludes implementation of this corrective action plan will avoid adverse impacts to water quality and the environment.

Tetra Tech’s analysis shows that, with few exceptions, the water quality standard exceedances observed in the TSF monitoring wells during 2009 were consistently the result of natural background concentrations present in the groundwater. It is important to understand that the TSF only received small amounts of tailings during the limited operating period.

Corrective Action Plan

In response to the corrective action requirement and to support the above findings, Tetra Tech conducted a detailed statistical analysis of baseline groundwater concentrations. This analysis supports establishing



new well-specific action levels for each water quality parameter that has recently exhibited exceedances. These new action levels reflect the concentrations at which potential adverse impacts on groundwater quality may actually occur, and for which AGC should take specific corrective actions to address the impact. The action levels reflect the Alaska WQS except where background levels exceed the WQS. Where such exceedances occur, the action levels represent the observed background concentrations. Compliance summaries, therefore, should continue to include exceedances of both the WQS and TCP action levels. Corrective actions, however, should only be implemented for water quality parameters where the new action levels are exceeded.

Groundwater trend data for 2009 (Figures B-1 – B-24) demonstrate that background concentrations for certain parameters, notably arsenic and manganese, are naturally elevated in the vicinity of the Rock Creek Mine. Figure B-2, for example, shows that arsenic concentrations in well MW06-8A are significantly higher than the WQS of 10 ug/L. Tetra Tech’s analysis also recognizes that there is considerable heterogeneity in groundwater conditions at each well. Each well, therefore, is considered as a separate dataset for the analysis. Additional detail on Tetra Tech’s methodology and results are presented in Attachment 1.

During 2009, monitoring well samples recorded the following exceedances of the proposed action levels:

• MW06-09A—Arsenic (1) and manganese (1) [Figures B-6 and B-7] • MW06-09B—Arsenic (2) and manganese (4) [Figures B-10 and B-11] • MW06-10A—Arsenic (1) [Figure B-14] • MW07-11—Antimony (7) and arsenic (1) [Figures B-17 and B-18] • MW08-15A—Arsenic (3) and manganese (2) [Figures B-22 and B-23]

The elevated arsenic and manganese values in MW06-09A were both observed on 2/10/2009 and are well above the long term averages for the year. Both values far exceed samples collected immediately prior to and following that date. An elevated total suspended solids concentration for the same sample (Figure B-25) strongly suggests the sample may have been contaminated and is possible invalid. The elevated arsenic and manganese values observed in MW06-09B occurred at the end of 2009. No cause has yet been identified. AGC will review subsequent monitoring data to determine any adverse trends at this sample point. The elevated arsenic value observed in MW06-10A was an isolated occurrence on 9/16/2006; subsequent samples have shown concentrations well below the proposed action level. Antimony levels in MW 07-11 steadily rose after injection began, reaching a maximum level of approximately 25 ug/L during September 2009. Subsequently, antimony levels have declined after AGC completed upgrades to the WTP that improved metals removal. In fact, the antimony level in the WTP effluent was consistently below 6 ug/L during the last quarter of 2009. AGC will continue to monitor the antimony level in MW07-11 during 2010 to evaluate whether it continues to decline towards the action level. The elevated arsenic value in MW07-11 was an isolated occurrence on 12/14/2009. AGC will continue to monitor arsenic levels in MW07-11 to determine if this value is indicative of any adverse trends.

There is insufficient background data to establish background-based action levels for monitoring well MW08-15A. As noted above, WTP effluent levels for the parameters listed in Table 13 are now consistently below water quality standards. As a result, AGC has assumed the late 2009 samples are representative of natural conditions and has not undertaken any corrective actions. During 2010, AGC will continue to review the data from MW08-15A to determine whether there are any detectable changes in water quality over time.

Re: Rock Creek Mine, Background Baseline Ground Water Quality Statistics

Project #: 114-31979

CC: Ron Rimelman; John Rozelle, Tetra Tech File

Introduction

Tetra Tech Inc. (TT) has analyzed the background data for groundwater quality at Alaska Gold Corporation’s (AGC) Rock Creek Mine site. This study is a continuation of a January 9, 2009 study done by SRK Consulting (2). Figure 1 shows the study area.

Figure 1. Sample Points

http://www.tetratech.com/�



The objective of this analysis to review the background ground water data and propose statistically derived action levels for constituents of concern (COC) for each groundwater monitoring well where background levels exceed the applicable WQS.

The site monitoring plan has been developed to meet the requirements of Title 18 Chapter 60 and 70 of the Alaska Administrative Code (AAC), set forth in Article 7 of 18.AAC.60; Monitoring and Corrective Action Requirements (Title 18 Chapter 60 Section 800-860) with the objective of meeting the requirements of 18 AAC 70.

The groundwater monitoring program reflects the following components of 18 AAC 60 and 18 AAC 70:

● 18.AAC.60.825(a-e) The monitoring system has been designed to meet the requirements in terms of location, design, local hydrogeological conditions, facility design, the ability to detect potential releases and local physiographic constraints.

● 18.AAC.60.825(a)(1)(B) Sampling at other wells will provide an indication of background groundwater quality that is at least as representative as that provided by upgradient wells.

● 18.AAC.60.825(c) Has established relevant points of compliance which reflect local hydrogeological conditions, the volume and physical and chemical characteristics of the leachate, the existing quality of the groundwater…

● Appropriate tolerance levels have been established for COCs to reflect background conditions and allow detection of statistically significant increases.

● Indicator parameters have been defined to reflect the composition and site-specific background water quality. These parameters have been selected as those most likely to give an unambiguous chemical signature at monitory locations in the event of a release from the tailings storage facility (TSF) and the Injection Well area (IW).

Based on these criteria, fourteen indicator parameters have been chosen:

1. antimony (total) 2. antimony (dissolved) 3. copper (dissolved) 4. cyanide WAD 5. molybdenum (dissolved) 6. nickel (dissolved) 7. nitrate+nitrite as N (total) 8. potassium (dissolved) 9. sodium (dissolved) 10. sulfate (dissolved), 11. total dissolved solids 12. arsenic (total) 13. arsenic (dissolved) 14. manganese (dissolved) The study area is divided into two separate study areas, the Tailings Storage Facility (TSF) area and the Injection Well (IW) area. The groundwater data show considerable heterogeneity in constituent concentrations from well to well. Therefore, each monitoring well has been considered as separate dataset for this statistical analysis of background levels. Several datasets were reviewed for this analysis. The baseline groundwater monitoring data predating the mining operation (latest data: March 25, 2008) came from the Rock Creek Project Alaska Department of Natural Resources web site (1). In addition, data from an SRK Consulting memo to AGC (2) and excel spreadsheets from AGC’s current environmental department was used.

1. TSF Study Area



The wells included in the TSF study area consisted of MW06_8a; MW06_9a, 9b; and MW06_10a. The wells designated with “a” refer to sampling from a deeper bedrock zone, while the “b” refers to a sampling of groundwater in the overburden.

2. The IW Area

The well included in the IW area consists of MW07_11.

Discussion of Statistical Analysis.

The wells were sampled before mining at the area commenced. Each of the selected indicator parameters was statistically analyzed to determine variability baseline using Tetra Tech’s GWLimits© (3) program. This program used the baseline data to produce the best estimates for the natural upper tolerance limit of background. Note that the term “Upper Tolerance Limit” refers to an estimated value for which a specified proportion of the population will be below. For example we can be 95% confident that at least p% of the population is below a specific UTL value.

The calculation of this threshold will vary according to what underlying theoretical population exists (Normal, Lognormal, Poisson), or no distribution at all (non-parametric). Given the baseline sample size is small; the choice of a correct distribution invariably produces better estimates of the upper tolerance limit. This study follows the EPA guidance in determining the appropriate distribution. EPA’s methods are discussed in detail within EPA’s ProUCL Technical Guide (4). In addition, the results from GWLimits program have been checked against ProUCL output.



Attached is the output of GWLimits. Several panels depicting the graphs and charts of each analyte over time are shown on each page. For example, page 1 of Appendix 1, shown also in Figure 1, presents the statistics for total antimony at well MW06-10A. The bottom panel of the figure charts the values (y-axis) as measured at each time (x-axis). The portion of the chart plotted in black represents the data measured before mining (background) and the chart plotted in red the values after mining commenced. Note that the last background sample was taken on 4/11/2008, while the first site value was taken eight months later on 12/10/2008. The four graphs in the panels above analyze the distribution of the background dataset. The graphs show the results in their original and log-transformed form. Each of the probability plots (Sample Quantiles vs. Theoretical Quantiles) generates a Shapiro-Wilk test, which determines if the distribution is normal, lognormal or non-parametric. For total antimony at MW06-10A, the test does not reject the hypothesis that the data follows a log-normal distribution at a p=0.05. Because of this last test, the program calculates the UTL using a lognormal distribution and plots its value as a horizontal red line if it exceeds the UTL established in Table 1. In the case of total antimony at MW06-10A, the calculated UTL is 5.74 ug/L does not exceed the assigned trigger value of 6.9 ug/L (plotted as a horizontal blue line). Hence, the calculated background UTL trigger is not plotted, and a “NS” code is displayed in the small plot key. It should be noted that all of the UTL values calculated by GWLimits, given an “NS” code were in fact very similar to the trigger permit values shown in Table 1.

Additional information such as the number of samples in the background data set; the selected distribution; the maximum, average, and standard deviation is presented in the plot key area. When a GW standard exists for an analyte, is value is plotted as a horizontal green line.

As a further example of the plots in the appendix, Figure 2 shows the output of the GWLimits program for total arsenic at well MW06-9a. Note that the calculated background UTL is 93 ug/L, which is well above the applicable WQS of 10 ug/L. In addition, there is an extreme spike measured at 201 ug/L on
