Specific objectives of the ground water monitoring conducted by RTK are to: 1) establish baseline ground water quality and hydrogeologic conditions; 2) identify areas where operations may have impacted ground water conditions; 3) monitor ground water quality in areas impacted by operations; 4) monitor progress of ground water cleanup efforts, 5) provide continued monitoring in the vicinity of current operations to detect ground water quality impacts should they occur; 6) collect data for use in the classification of ground water; and, 7) comply with permit requirements. The purpose of this Ground Water Characterization and Monitoring Plan is to set forth a project plan which utilizes standardized procedures and methods for the collection and review of ground water monitoring data. The following documents are incorporated within this Plan: 1) Health and Safety Plan; 2) Quality Assurance Project Plan; and 3) Standard Operating Procedures for Ground Water Sampling. The Health and Safety Plan addresses health and safety requirements for the conduct of the field work. The Quality Assurance Project Plan presents: 1) project organization and responsibilities; 2) quality assurance objectives for the collection of data in terms of precision, accuracy, representativeness, comparability, and completeness; 3) analytical procedures; and 4) guidelines for data verification and reporting, internal quality control checks, performance and systems audits, and corrective actions. The Standard Operating Procedures include all field activities associated with ground water sampling. Together these documents provide a systematic approach to be used in the collection of ground water monitoring data and the evaluation of regional baseline conditions when needed. The guidance and standard operating procedures will help to ensure a technically sound and defensible ground water characterization and monitoring program. 3 SUMMARY ........................................................................................................................................................................ 2 SECTION 1 OVERVIEW .................................................................................................................................................... 4 1.1 OBJECTIVES ............................................................................................................................................................... 4 1.2 PURPOSE OF PLAN ..................................................................................................................................................... 4 SECTION 2 SITE SETTING AND BACKGROUND .......................................................................................................... 5 SECTION 3 INITIAL EVALUATION .................................................................................................................................. 5 3.1 GROUND WATER ........................................................................................................................................................ 5 SECTION 4 RATIONALE .................................................................................................................................................. 6 4.1 OBJECTIVES AND APPROACH ...................................................................................................................................... 6 4.2 MONITORING WELL SELECTION ................................................................................................................................... 6 4.2.1 Great Salt Lake Area ........................................................................................................................................ 6 4.2.2 Southwest Jordan Valley Area .......................................................................................................................... 8 4.2.3 Regulatory Monitoring Requirements ............................................................................................................. 10 4.3 SELECTION OF ANALYTICAL PARAMETERS ................................................................................................................. 10 4.4 DATA QUALITY OBJECTIVES ...................................................................................................................................... 12 SECTION 5 TASKS ......................................................................................................................................................... 13 5.1 TASK 1 - PROJECT PLANNING AND QUALITY ASSURANCE ............................................................................ 13 5.2 TASK 2 - SAMPLE POINT SELECTION ................................................................................................................ 13 5.2.1 Addition of New Monitoring Points .................................................................................................................. 14 5.3 TASK 3 – SAMPLING ............................................................................................................................................. 14 5.4 TASK 4 - SITE-WIDE WATER LEVEL MEASUREMENTS .................................................................................... 14 5.5 TASK 5 - VERIFICATION OF RESULTS AND DATA EVALUATION ..................................................................... 14 5.6 TASK 6 - WELL ABANDONMENT ......................................................................................................................... 15 5.7 TASK 7 - NEW WELL CONSTRUCTION ............................................................................................................... 15 5.8 TASK 8 - GROUND WATER CHARACTERIZATION AND MONITORING REPORTS ......................................... 15 5.9 TASK 9 - UPDATE OF GROUND WATER CHARACTERIZATION AND MONITORING PLAN ............................. 16 SECTION 6 SCHEDULE ................................................................................................................................................. 16 SECTION 7 PROJECT MANAGEMENT ......................................................................................................................... 16 7.1 PROJECT ORGANIZATION .................................................................................................................................. 16 SECTION 8 REFERENCES .............................................................................................................................................. 8 ATTACHMENTS Attachment 1.

Standard Operation Procedures for Ground Water Sampling 4 SECTION 1 OVERVIEW 1.1 Objectives RTK currently utilizes an extensive ground water monitoring system to monitor the ground water levels and water quality in the vicinity of its facilities. Specific objectives of the ground water monitoring program conducted by RTK have been to: • Establish baseline ground water quality and hydrogeologic conditions. • Identify areas where operations may have impacted ground water quality. • Monitor ground water quality in areas impacted by operations. • Monitor progress of ground water cleanup efforts. • Provide continued monitoring in the vicinity of current operations to detect ground water quality changes should they occur. • Assess adequacy of source control measures. • Support the determination of ground water classifications; and • Comply with permit monitoring requirements. 1.2 Purpose of Plan The purpose of this Ground Water Characterization and Monitoring Plan (GCMP) is to establish a project plan which standardizes procedures and methods for the collection, analysis and reporting of ground water monitoring data. Therefore, a systematic approach will be used in the collection of monitoring data and the evaluation of ground water quality. This document identifies the goals and objectives of the program and identifies project tasks. Requirements for data reporting and review, as well as periodic review of this Plan are included, along with the following documents: • Health and Safety Plan (HSP). • Quality Assurance Project Plan (QAPP). • Standard Operating Procedures for Water Sampling (SOP). The HSP addresses health and safety requirements for conducting fieldwork. The QAPP presents: 1) project organization and responsibilities; 2) quality assurance objectives for the collection of data in terms of precision, accuracy, representativeness, comparability, and completeness; 3) analytical parameters; and 4) guidelines for data verification and reporting, internal quality control checks, performance and systems audits, and corrective actions. The SOP presents standard operating procedures for field activities, including ground water sample collection and field measurements. Site-specific project plans to evaluate contaminant sources, plume migration, and any need for remedial actions will be developed as necessary, independent of this 5 GCMP. However, the procedures presented here will be used to collect the necessary data for such evaluations. As the need for additional field procedures and data evaluation techniques becomes evident during the planning and implementation of such projects, this GCMP will be amended to include those items. Monitoring locations, analytical parameters, and frequency of sampling will also be reviewed and updated regularly (unless specified in permits) as directed in this GCMP. Updates will be based on an analysis of results for each sampling point and the data needs for specific facility areas. SECTION 2 SITE SETTING AND BACKGROUND This section provides the site setting as well as background information on operations and monitoring conducted on RTK property. For discussion purposes, the property is subdivided into two areas, the Great Salt Lake Area (GSL) and the Southwest Jordan Valley Area (SWJV). The SWJV area includes all areas associated with the Bingham Mine and the Copperton Concentrator. Features include the Mine, the leach water collection system, the leach and storm water reservoirs and the historic evaporation ponds. The locations of ground water monitoring points for the SWJV Area are shown in Plate 2. The GSL area includes the general area of the Utah Copper facilities associated with the concentrating, tailings disposal, smelting, and refining of metals. The locations of established ground water monitoring points are shown in Plate 1. RTK has conducted two Remedial Investigation and Feasibility Studies (RI/FS) of mining- related contamination in groundwater. The first RI/FS is the area east of the mine dumps in the southwestern Jordan Valley. The second RI/FS consists of the areas beneath and down-gradient of the Smelter and Refinery. In addition, other extensive ground water studies completed in these areas have resulted in the acquisition of baseline ground water data. The hydrogeologic setting and current ground water conditions beneath RTK property are described in the "Hydrogeologic Report for the Great Salt Lake Area" (KUC, 1992a) and in "Ground Water Assessment Report the Southwestern Jordan Valley Area" (KUC, 1992b). Ground water impacts may result from natural leaching of mineralized outcroppings, commercial leaching processes, ground water pumping, storage of water in surface water impoundments, seepage from irrigation and water supply canals, and the infiltration of precipitation. In order for RTK to evaluate the potential past and present impacts on ground water beneath and near its facilities, RTK has established a ground water monitoring network to monitor and evaluate ground water conditions. Wells utilized in the ground water monitoring network include RTK monitoring wells, State, City, and County monitoring wells, RTK production wells, and public and residential supply wells. SECTION 3 INITIAL EVALUATION 3.1 Ground Water Ground water samples have previously been collected from many of the monitoring wells included in this monitoring program. Samples were predominately collected by 6 the RTK Sampling Crews and analyzed by the RTK Environmental Laboratory. The analytical results for samples collected and analyzed by RTK and sampling performed by others are contained in the RTK Environmental Laboratory Information Management System (LIMS) and are summarized in Attachments to the Ground Water Characterization and Monitoring Plan issued in April of 1992. Data collected are presented in the Quarterly Ground Water Characterization and Monitoring Reports and Quarterly Quality Assurance Reports. SECTION 4 RATIONALE 4.1 Objectives and Approach The general objective of this monitoring program is to better define and document current ground water quality conditions near RTK's operations. Annual data reviews and evaluations will determine the number and frequency of sampling points monitored to achieve the objectives. This document identifies the procedures to be used to evaluate and modify the number of points sampled and the sampling frequency. 4.2 Monitoring Well Selection Monitoring well selection is grouped into three categories: 1) Objectives of ground water monitoring in the Great Salt Lake area, 2) Objectives of ground water monitoring in the southwestern Jordan Valley, and 3) Regulatory required sampling in both of these areas. Detailed information used to define the objectives of the monitoring programs in the GSL area and the SWJV is compiled in two remedial investigations and feasibility studies (RI/FS) of mining-related contamination in groundwater. Both are conducted by RTK. The following sections identify the sampling points included in this GCMP and the general rationale for their inclusion. Sample point locations are shown on Plates 1 and 2. Ground water monitoring well construction details in Attachment 1. The hydrogeologic conditions and types of operations vary depending on site location and facility use. Therefore, the monitoring programs in each location have different objectives and approaches. Table 1 is an example of a monitoring schedule included in the Annual Report, which summarizes the rationale for the wells, current monitoring frequencies, and monitoring parameters proposed for the current monitoring program. The rationale for selection of the monitoring points is summarized in the following sections. 4.2.1 Great Salt Lake Area The general objective of the monitoring program for the Great Salt Lake Area is to establish and document current local ground water and surface water conditions and trends and to collect the data required to meet existing, as well as anticipated future, regulatory requirements. A summary of ground water conditions in this area is provided in the "Hydrogeologic Report for the Great Salt Lake Area" (RTK, 1992a.) 7 There exists an extensive network of shallow and deep ground water monitoring wells and piezometers in the GSL area. The monitoring wells included in this GCMP were installed near facilities at the north end of RTK property to monitor potential effects resulting from the Tailings Impoundment, Refinery, Smelter, as well as potential effects from other facilities. These wells were used to establish the areal and vertical distribution of aquifers and aquitards, the direction and velocity of ground water flow in and between each aquifer, and the chemical composition of the water in each aquifer. State, County, and City monitoring wells were used to investigate ground water conditions near the Tailings Impoundment and in the vicinity of the City and County landfills up-gradient of the Tailings Impoundment (Slam 1989a, 1989b). These wells were included in the monitoring program in 1991 in order to further document the ground water conditions but will no longer be sampled. 4.2.1.1 Baseline Program In order to accomplish the monitoring objectives identified for the GSL area, a program of baseline monitoring was established. The basis of this program was to collect four quarterly rounds of ground water samples for a comprehensive suite of analytes from each well. After collection of the baseline data, these monitoring data were reviewed to evaluate the need for continued monitoring, the need for expansion of the monitoring system, and the types of analyses required. 4.2.1.2 North Zone Groundwater The general objective of the monitoring program in the North Zone Groundwater Operation, Maintenance, and Replacement Plan (OM&R Plan) (in preparation) is to track the nature and extent of ground water contamination from the smelter and refinery. Specifically, the program: 1. monitors the natural attenuation of the selenium plume from the refinery. 2. monitors the natural attenuation of the selenium and arsenic plumes at the smelter. 3. monitors the effectiveness of source control actions taken at the smelter and refinery and 4. provides baseline data concerning background water quality. Oversight for the OM&R Plan is provided by Environmental Protection Agency Region VIII (EPA), Utah Department of Environmental Quality (UDEQ), and a Technical Review Committee (TRC) of various interested parties. The OM&R Plan interfaces with the GCMP in two significant areas. First, all of the data generated and used in the OM&R Plan is collected from monitoring wells that are part of the GCMP. The second important relationship between the OM&R Plan and the GCMP is that all of the water data collected required for the OM&R Plan is subjected to the quality assurance/quality control (QA/QC) standards established in the GCMP. 8 4.2.2.3 Continued Monitoring Program All baseline data have been reviewed to evaluate additional monitoring requirements. Evaluation of these requirements were based on the following: • Aberrant data - Graphs of analytical parameters as a function of time were constructed to identify data that appear to be erroneous or deviate significantly from established data trends. If these aberrant data appeared to significantly affect the interpretation of the data for the well, additional frequent monitoring was recommended. This consideration was generally limited to the analytical constituents TDS, As, Se, Cu and Cd. • Identification of significant temporal data trends - Evaluation of the existing data indicates many current temporal changes in the data. These changes imply that ground water conditions are changing in response to some stimulus. In many cases, these changes appear to be in response to seasonal fluctuation or other observable factors effecting ground water conditions. Where these trends are unusual, unexplained, and or appear to be significant to the understanding of ground water conditions, the wells displaying these changes were selected for additional monitoring at a frequency that would further document the presence or absence of the trend. • Establishment of a longer or more detailed sampling history - Review of the data showed many wells in which the variation of critical analytes was greater or less than expected and additional analyses are required to identify the nature and extent of the variation. Long-term monitoring of potentially affected wells - In a number of cases, particularly in the vicinity of the Refinery, wells were identified that may have been affected by RTK operations. Current Wells and sampling frequencies for project plans are based on one or more of the factors identified above and are identified and submitted in the Annual Report Table 1. 4.2.2 Southwest Jordan Valley Area The general objective of the monitoring program in the Southwest Jordan Valley Area is to monitor groundwater plume containment and cleanup in order to meet RTK monitoring obligations under the South Facilities Groundwater Operations, Maintenance, and Replacement Plan (RTK, 2009). Specifically, the program: 1. monitors the containment and cleanup of the low pH and elevated metals plume. 2. monitors the containment and cleanup of the plume containing elevated sulfate/TDS concentrations. 3. monitors the effectiveness of the leach collection system at the toe of the waste rock dumps. 4. monitors the water quality in the areas near 11800 South Street where municipal, domestic and irrigation water supply wells are located near or down gradient of the elevated sulfate/TDS plume. 9 5. meets existing, as well as, anticipated future monitoring requirements; and 6. provides baseline data concerning background water quality. The program will also monitor the effectiveness of source-control actions at the Bingham Reservoir and the Eastside Collection System. Areas affected by RTK and pre-RTK operations have been defined using the existing database. A summary of the ground water and surface water results provided to date are given in "Ground Water Assessment Report of the Southwestern Jordan Valley Utah" (KUC, 1992b, RIFS KUC 1998, and RD/RA KUC 2002). The 1998 SWJV RI report documents the field investigations conducted by RTK, presents the site characteristics, assesses the nature and extent of mining-related contamination, provides human health and ecological risk assessments, and offers conclusions regarding the risk to human health and the environment posed by mining related contamination. The study area covered by the RI extends from the RTK waste rock disposal areas on the eastern edge of the Oquirrh Mountains to the Jordan River. It is bounded on the north at approximately 7800 South Street and on the south by the foothills of the Traverse Mountains. RTK funded and conducted the work for the RI/FS with oversight by the U.S. Environmental Protection Agency (EPA) Region VIII, the State of Utah Department of Environmental Quality (UDEQ) and a Technical Review Committee (TRC). The activities conducted by RTK were consistent with applicable guidance under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA also known as Superfund), and with requirements of the National Contingency Plan (NCP). In addition to the RI report, a well inventory of the SWJV was conducted to determine the existence and use of all wells in the southwest part of the valley. This information has been used to review current GCMP sampling locations and identify changes to be made in future GCMP schedules. 4.2.2.1 Continued Monitoring Program Sampling of a select group of wells associated with the Bingham Creek Reservoir low-pH, elevated-metals plume will generally occur biannually in order to monitor chemistry changes associated with extraction of the plume. On the leading (eastern) edge of the low-pH plume, monitoring of select wells will occur on a semiannual basis to track advancement of the plume. All samples from these wells will be analyzed for Basic and Major analytical suites plus dissolved iron, aluminum, manganese, and acidity. Selected wells completed in portions of the aquifer that contain elevated sulfate but not low-pH will be monitored for Basic and Major group analytes. These wells are mostly completed in the halo of elevated sulfate surrounding the Bingham Creek Reservoir low-pH plume. Key wells located in the areas between and around the B2G1193–BFG1200 and West Jordan City well fields will be sampled on a quarterly, semiannual or annual 10 basis to monitor movement of the elevated-sulfate plume. All samples from these wells will be analyzed for Basic group analytes and some for Major group analytes as well. The higher monitoring frequency of these wells over those previously listed is warranted by concerns of potential effects on third party interests. Other wells that are sampled because of third party concerns include privately or municipally owned wells and RTK wells completed near areas where third parties are using water, such as irrigation wells near the elevated-sulfate plume east of the Former RTK Evaporation Ponds. Many monitoring wells located immediately down-gradient of the leach collection system are included in regulatory monitoring and are listed in the following section. A few wells located in this area but not included in any permit required monitoring program will be sampled annually for Basic and Major analytical suites. Several wells will be monitored for changes in Basic and Major group analytes as part of approved Drinking Water Source Protection plans, and several production wells will be sampled quarterly or annually to monitor water quality used at various RTK facilities. 4.2.3 Regulatory Monitoring Requirements RTK has six groundwater discharge permits issued by the State of Utah which require groundwater monitoring for compliance with the permits. Portions of both the SWJV and GSL are under one or more of the following permits: • Large and Small Bingham Reservoirs - UGW350006 • Smelter – UGW350008 • Bingham Canyon Mine and Water Collection System – UGW350010 • Tailings Impoundment – UGW350011 • Magna Process Water Reservoir Facility – UGW350015 • Copperton Concentrator – UGW350017 • Barneys Canyon – UGW350001 4.3 Selection of Analytical Parameters Based on the review of the existing data and regulatory (potential as well as existing) requirements, different groups of analytical parameters have been identified as listed below: • Basic • Major Ions • Minor Ions • Trace Metals 1, Trace Metals 2, Trace Metals 3 • Mercury • Radionuclides • Other. 11 Basic The basic group of analyses is comprised of the analytes that are sensitive to changes in ground water quality that could result from RTK's operations. The analytes included in the basic group are listed in Table 2 and include conductivity, pH, TDS, TSS, sulfate, chloride. Arsenic, selenium, copper, lead, zinc, and cadmium are analyzed for dissolved concentrations only unless totals are requested. Significant changes in ground water conditions potentially caused by RTK's operations can be detected early through monitoring of only these analytes. Major Ions The Major Ions group, when combined with the Basic Parameter group provides sufficient analyses to allow for the calculation of ionic and mass balances. This list of constituents is required for all wells monitored to satisfy monitoring requirements to meet the conditions of Ground Water Discharge Permits. The analyses included in Major Ion group are listed in Table 2 and include: alkalinity, calcium, potassium, magnesium, and sodium. Minor Ions The Minor Ion group adds some minor ions and indicator parameters that provide additional insight into the nature of the water sampled. The primary use of these constituents is for the initial characterization of water chemistry. This group is commonly monitored where the water is believed to be at a reducing potential. The analyses included in the Minor Ion group are listed in Table 2 and include: fluoride, nitrate, nitrite, phosphorus, dissolved oxygen, Eh, ferrous iron, and sulfide. Trace Metals The trace metals have been divided into three groups as follows: Trace Metals 1 This group includes the trace metals barium, chromium, and silver. These metals are the most commonly requested trace metals. These trace metals have MCL’s under the Safe Drinking Water Act (SDWA) and with the basic group from above contain the eight RCRA metals. Trace Metals 2 This group includes the metals iron, manganese, molybdenum, and nickel. These metals are added to include the common trace metals that have only secondary standards under the SDWA. Trace Metals 3 This group includes the trace metals aluminum, antimony, beryllium, boron, thallium, and titanium, which are rarely requested. Radionuclides The radionuclide group includes the analytes: radium 226, radium 228, total uranium, gross alpha and gross beta. This list of constituents is required for wells monitored to satisfy the conditions of the Ground Water Discharge Permit for the Tailings Impoundment in the area near the former Gypsum Tailings Impoundment. 12 Mercury Mercury analysis is done on total metals only. The analysis is to satisfy the requirements of the ground water discharge permits as well as some of the drinking water requirements. Other This is used to request additional analytes such as Cyanide (CN), Nitrates, Total Petroleum Hydrocarbons (TPH), Benzene, Toluene, Ethyl Benzene, Xylene, and Naphthalene (BTEX-N) et al. In addition, a new category listed in this group as “Balance” will include the trace metals aluminum, iron, manganese, and also acidity. This category when requested on low pH water samples will provide a more complete geochemical analysis to obtain and calculate a charge balance. 4.4 Data Quality Objectives Data Review The results of all sampling will be reviewed by the Project Manager (Principal Advisor Water Quality) or his designee upon receipt of analytical results from the laboratory. If based on a timely review of analytical data, any significant questions are raised regarding the quality or representativeness of the results, the well will be re-sampled. Objectives The data quality objectives of this Plan are discussed in detail in the Quality Assurance Project Plan (QAPP) and summarized below: • The precision objectives for analytical and field methods are: 1) within 25% of the relative percent difference or + (4) times the MDL (per 40 CFR Part 136, Ap. B Rev 1.1, July 1, 1992) whichever is greater, for duplicate samples; and 2) 75% to 125% recovery for matrix spike duplicates (70% to 130% for organic compounds). It is recognized that these objectives may not be appropriate for certain parameters and for high TDS water; particularly containing high levels of chloride and sulfate. • The accuracy objectives for analytical and field methods are: 1) less than the method quantitation limit for blank; and 2) 75% to 125% recovery for spikes if the concentration is 10 times or greater than the MDL, (70% to 130% for organic compounds). These objectives have been identified for relatively low TDS water and will vary with TDS. • All sample collection and measurements will be performed in accordance with protocols and procedures documented in the QAPP and SOP to assure sample representativeness. All RTK Environmental and Industrial Hygiene Laboratory Procedures are available on the RTK Intranet. These documents are controlled through the Documentum Program. 13 • Every effort will be made to achieve data collection completeness. • Comparability of data will be accomplished through the use of standard operating procedures. SECTION 5 TASKS The following tasks have been identified for the Ground Water Characterization and Monitoring Plan: TASK 1 Project Planning and Quality Assurance TASK 2 Sample Point Selection TASK 3 Sampling TASK 4 Site-wide Water-level Measurements TASK 5 Verification of Results and Data Evaluation TASK 6 Well Abandonment TASK 7 New Well Construction TASK 8 Annual Ground Water Characterization and Monitoring Reports TASK 9 Periodic Update of Ground Water Characterization and Monitoring Plan 5.1 TASK 1 - PROJECT PLANNING AND QUALITY ASSURANCE This task consists of the planning, preparation, quality assurance planning, and coordination required maintaining and fully implementing this Plan. Project planning will continue throughout the project to ensure the achievement of project objectives. The process for reviewing and updating the Ground Water Characterization and Monitoring Plan is discussed in Task 9. Quality assurance planning is documented in the QAPP. The QAPP lists the quality control samples to be collected in conjunction with routine monitoring in order to measure the precision, accuracy, representativeness, and comparability of field and laboratory techniques. Guidelines for data verification and reduction, internal quality control checks, performance and systems audits, and corrective actions are also presented in the QAPP. 5.2 TASK 2 - SAMPLE POINT SELECTION Wells considered for sampling were selected from the following groups of wells: • RTK monitoring wells and piezometer • RTK production wells • State, county, and city monitoring wells • Public and residential wells • Municipal wells. The selected wells and sampling frequency for these wells are listed in the current Annual Report in Table 1. The general objectives and rationale for the selection of these wells are discussed in section 4. 14 5.2.1 Addition of New Monitoring Points Additional sampling points may be added to the monitoring program at a future date, provided that the rationale for the addition of a sampling site is documented by submitting a Well Approval Form to the Project Manager for approval prior to inclusion to the network. Potential rationale for expanding the monitoring program includes the identification of sampling points located in critical areas, replacement of existing sampling points which must be abandoned, and the identification of problem areas. Such documentation (to be filed in the Water Quality Data Filing System) will include monitoring parameters, monitoring frequency, and previously collected monitoring data. 5.3 TASK 3 – SAMPLING Water sampling activities will be conducted in accordance with the Standard Operating Procedures (SOP). Procedures to be used in the collection of water samples include: DC-01 through DC-07 Sample Documentation and Sample Handling MD-01 through MD-03 Equipment Maintenance and Decontamination QC-01 through QC-05 Quality Control Sampling GF-01 through GF-16 Measurement of Field Parameters GW-01 through GW-14 Collection of Ground Water Samples PW-01 through PW-15 Collection of Process Water Samples DW-01 through DW-09 Collection of Drinking Water Samples SW-01 through SW-11 Collection of Surface Water Samples SS-01 through SS-05 Collection of Sediment Samples. 5.4 TASK 4 - SITE-WIDE WATER LEVEL MEASUREMENTS In addition to the water level or hydraulic head measurements taken prior to each sampling event, annual water level measurements, in select, monitoring wells will be made. These water levels will be completed as required by permit conditions and/or the needs of special projects. The measurements will be taken during the shortest elapsed time period that is feasible. Site-wide water-level measurements will allow an evaluation of the relationships between surface water and the ground water potentiometric surface. Such determinations are not possible using measurements taken at the time of sampling over several weeks or months. Potentiometric information is required in order to evaluate the ground water regime with respect to flow velocity and direction. Details of the methods and procedures used to conduct these measurements are provided in the SOP. 5.5 TASK 5 - VERIFICATION OF RESULTS AND DATA EVALUATION Verification of analytical results will include ion balances (when complete analyses are conducted for major cations and anions), statistical checks against previous results, and spot checks of data transfer. Data management 15 is described in Section 5 of the QAPP. 5.6 TASK 6 - WELL ABANDONMENT A monitoring well must be properly abandoned (i.e., filled or plugged with an "impermeable" material) if it will no longer be used due to the availability of nearby wells, access problems, susceptibility to flooding, lack of water in well, well construction problems, or impending destruction due to construction activities on RTK property. A well must also be abandoned if the integrity of the annulus seal is in question. Lack of proper abandonment may result in a pathway for surface spills or cross-contamination between aquifers of different depth and quality. All monitoring well abandonments will be done in compliance with State of Utah Administrative Rules for Water Well Drillers. Procedures for monitoring well abandonment are provided in the SOP. 5.7 TASK 7 - NEW WELL CONSTRUCTION The Project Manager assigned to a well installation project will select the appropriate drilling method based on expected subsurface conditions. The auger or vibratory sonic methods are appropriate for wells in lake bottom sediments (unconsolidated materials) to depths of about 100 feet. Vibratory sonic and mud or air rotary and cable tool are appropriate for unconsolidated and consolidated formations of greater depths. The water or mud used with rotary or cable tool methods must be free of contaminants and of a known composition. Procedures for new well construction are provided in the SOP. 5.8 TASK 8 - GROUND WATER CHARACTERIZATION AND MONITORING REPORTS Brief reports will be written within 90 days after the end of each quarter for internal use to summarize results for the previous three months. An Annual Ground Water Characterization and Monitoring Report will present the results of the previous year's monitoring and the proposed monitoring plan for the current year. This report will be prepared by March 31 for each monitoring year (e.g., January 1 through December 31) to allow a three-month turnaround time for laboratory analyses and report preparation. The report outline will generally adhere to the following: 1.0 Summary 2.0 Introduction 3.0 Quality Assurance Summary 4.0 Summary of Water Quality Analyses 5.0 Ground Water Characterization 6.0 Well Abandonment 7.0 New Well Construction 8.0 Program Changes 9.0 Recommendations for Program Changes 16 5.9 TASK 9 - UPDATE OF GROUND WATER CHARACTERIZATION AND MONITORING PLAN The Ground Water Characterization and Monitoring Plan is a working document. Updates may be made by documenting the change to the file and reporting the change in the quarterly and annual monitoring reports. The Supervisor Sampling will review this Plan in September of each year. After completion of this review, the manager will determine whether or not a formal revision is needed. The Utah State Division of Water Quality will be notified prior to implementing any changes to this document that will significantly affect the collection and analysis of regulatory required samples. SECTION 6 SCHEDULE A comprehensive sampling and monitoring schedule of sampling at each point will be included in the Annual Reports Table 1. Water levels are to be measured as required by the sampling schedule in the Table 1. Annual measurements will be done in the summer or late fall. SECTION 7 PROJECT MANAGEMENT 7.1 PROJECT ORGANIZATION The organizational structure for implementing the ground water sampling efforts is shown in Figure 1. Responsibilities of each of the positions are described in Section 2 of the Quality Assurance Project Plan. FIGURE-GCMP 1.

Health and Safety Plan All RTK employees will adhere to the following documents: RTK's Safety and Facilities Standards Manual and the Safety and Health Policy stated therein; and, RTK’s Environmental Response Health and Safety Plan The sampling crew will attend site-specific training annually or as required at each plant. In general, crewmembers will wear all required PPE and abide to all safety rules and regulations at each plant Existing site information indicates that heavy metals in the soil are not present at hazardous levels that could pose a significant risk to sampling crew while conducting sampling. Historical ground water and surface water monitoring data do not warrant health concerns related to skin exposure or vapor inhalation. Therefore, no special procedures or protective equipment is required during sampling. Well abandonment and installation activities pose a potentially higher health and safety risk to on-site personnel. Therefore, site-specific health and safety plans will be developed for each project. Attachment 2. Quality Assurance Project Plan Attachment 3. Standard Operation Procedures for Ground Water Sampling
