Attachment F – Proposed Relocation of Outfall 016 (not yet constructed) Attachment F contains details on Outfall 016 (to be constructed as a stilling well). This outfall was initially proposed to be located entering Pink Lake upstream of Alkali Creek. Aethon has relocated the associated pipeline route such that the stilling well is now located at Alkali Creek. The proposed pipeline from Outfall 001 to Alkali Creek was submitted to the BLM(Lander) in May 2016 and Aethon plans to construct the pipeline and stilling well upon their approval. Coordinates for Outfall 016 in Table 1 include the current proposed location. Attachment G – Work Plan for the Boysen Reservoir Water Quality Assessment – Modeling in Progress Attachment G describes the Work Plan for the Boysen Reservoir Water Quality Assessment. Aethon worked with WDEQ to ensure the Work Plan included aspects necessary to develop a defensible and robust modeling approach. Pending completion of the modeling work described in the assessment, Aethon requests 1) relief from the monthly salt load limit of 908 tons/month and 2) WDEQ establish permit limits for applicable water quality parameters based on projections from the watershed (SWAT) and reservoir (GEMSS) models.

Precautions for safe handling

7/24/2015. RBW213 4/9


Section 8. Exposure controls/personal protection

Hand protection

If a risk assessment indicates it is necessary, use a properly fitted, air purifying or supplied air respirator complying with an approved standard. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product and the safe working limits of the selected respirator.

Wear chemical safety goggles. When transferring material wear face-shield in addition to chemical safety goggles. If inhalation hazards exist, a full-face respirator may be required instead.

Eye/face protection

Respiratory protection :

:

:

Skin protection Wear long sleeves and chemical resistant apron to prevent repeated or prolonged skin contact.

:

Appropriate engineering controls

: If user operations generate dust, fumes, gas, vapor or mist, use process enclosures,local exhaust ventilation or other engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits.

Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period.Appropriate techniques should be used to remove potentially contaminated clothing.Wash contaminated clothing before reusing. Ensure that eyewash stations and safety showers are close to the workstation location.

Promptly isolate the scene by removing all persons from the vicinity of the incident if there is a fire. No action shall be taken involving any personal risk or without suitable training. Move containers from fire area if this can be done without risk. Use water spray to keep fire-exposed containers cool.



carbon dioxide,carbon monoxide,nitrogen oxides,phosphorus oxides,halogenated compounds

Flammable liquid and vapor. In a fire or if heated, a pressure increase will occur and the container may burst, with the risk of a subsequent explosion. The vapor/gas is heavier than air and will spread along the ground. Vapors may accumulate in low or confined areas or travel a considerable distance to a source of ignition and flash back.Runoff to sewer may create fire or explosion hazard.



Use dry chemical, CO₂, water spray (fog) or foam.

Stop leak if without risk. Move containers from spill area. Use spark-proof tools and explosion-proof equipment. Approach release from upwind. Dike spill area and do not allow product to reach sewage system or surface or ground water. Notify any reportable spill to authorities. (See section 12 for environmental risks and 13 for disposal information.) Wash spillages into an effluent treatment plant or proceed as follows.Contain and collect spillage with non-combustible, absorbent material e.g. sand, earth,vermiculite or diatomaceous earth and place in container for disposal according to local regulations (see Section 13). Dispose of via a licensed waste disposal contractor.Contaminated absorbent material may pose the same hazard as the spilled product.Note: see Section 1 for emergency contact information and Section 13 for waste disposal.

:

: No action shall be taken involving any personal risk or without suitable training.Evacuate surrounding areas. Keep unnecessary and unprotected personnel from entering. Do not touch or walk through spilled material. Shut off all ignition sources.No flares, smoking or flames in hazard area. Avoid breathing vapor or mist. Provide adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Put on appropriate personal protective equipment.


Large spill :

Stop leak if without risk. Move containers from spill area. Use spark-proof tools and explosion-proof equipment. Dilute with water and mop up if water-soluble. Alternatively,or if water-insoluble, absorb with an inert dry material and place in an appropriate waste disposal container. Dispose of via a licensed waste disposal contractor.

:

Protective measures Put on appropriate personal protective equipment (see Section 8). Do not get in eyes or on skin or clothing. Do not breathe vapor or mist. Do not ingest. Use only with adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Do not enter storage areas and confined spaces unless adequately ventilated. Keep in the original container or an approved alternative made from a compatible material, kept tightly closed when not in use. Store and use away from heat, sparks, open flame or any other ignition source. Use explosion-proof electrical (ventilating, lighting and material handling) equipment. Use only non-sparking tools. Take precautionary measures against electrostatic discharges. Empty containers retain product residue and can be hazardous. Do not reuse container.

:




: Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or other engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits. The engineering controls also need to keep gas,vapor or dust concentrations below any lower explosive limits. Use explosion-proof ventilation equipment.

Boysen Reservoir TDS Assessment – Modeling in Progress

APPENDIX A: BOYSEN RESERVOIR WATER QUALITY ASSESSMENT

2 May 2017

OBJECTIVE

ERM has recently completed an initial channel stability and water quality study for the Moneta Divide field. During this study, a set of evaluations were completed including the assessment of channel morphology, assessment of water quality (TDS) in Alkali Creek, Badwater Creek and Boysen Reservoir, and assessment of other engineering and environmental measures to minimize potential impacts of increases in Moneta Divide produced water discharge. To assist with some of these evaluations, a Boysen Reservoir catchment model was developed that provided seasonal and annual flow inputs. The water quality (TDS) assessment used a combination of 1-D water quality model and mass balance approaches to evaluate incremental contribution of Moneta Divide discharge to TDS levels in Boysen Reservoir. Since the evaluation was a screening assessment to identify key sensitivities to the TDS levels in Boysen Reservoir, simplified steady state calculations were sufficient. The outcome of the study suggests that a more comprehensive and dynamic (temporally varying) model of Boysen Reservoir is necessary. Furthermore, it is also important to study Boysen Reservoir with more detailed spatial resolution such that the dynamic interaction of all 11 streams draining into the reservoir can be appropriately captured. The plan outlined in this document aims to accomplish this detailed assessment by:

calibrating and validating the catchment model based on Soil and Water Assessment Tool (SWAT) to available flow data;

expanding the existing catchment model to include natural TDS (and the other WQ parameters listed on Page 6) loads in all contributing streams;

calibrating and validating, to the extent possible, SWAT computed river TDS (and other WQ parameters listed on Page 6) loads to reproduce measured concentrations in Wind River;

identifying flow scenarios including actual, typical and extreme (drought conditions); implementing a comprehensive water quality model based on 3-dimensional

discretization of Boysen Reservoir and seasonally varying loads; developing a computational baseline within Boysen Reservoir and Wind River

downstream of Boysen Reservoir for all water quality parameters (listed on Page 6) based on existing operations;

estimating projected water quality for all parameters (listed on Page 6) within Boysen Reservoir under various Moneta Divide discharge scenarios;

estimating projected water quality concentrations in Wind River downstream of Boysen Reservoir under various Moneta Divide discharge scenarios; and

identifying bounding Moneta Divide discharge loads such that Wind River water quality downstream of Boysen Reservoir does not deviate from the baseline by more

than 10% (or an alternate limit) of the current observed levels. Additionally one standard deviation from seasonal values will be evaluated.

The work plan below is organized such that it discusses all of these key elements in detail. The work plan also provides a summary of a comprehensive data inventory exercise conducted to evaluate the availability of sufficient and accurate data for model calibration tasks.

EXISTING DATA

BATHYMETRIC DATA

U.S. Bureau of Reclamation had conducted a “Boysen Reservoir Sedimentation Survey” in 1994 and published in 1996. The report summarizing this survey is available publically. Through the Freedom of Information Act (FOIA), ERM received the digital files of the 1994 bathymetric data. Upon review of the 22 year old bathymetric survey, Aethon Energy has elected to perform a bathymetric survey of Boysen Reservoir. Apex Survey out of Riverton, WY is in the process of conducting the survey. The work plan proposes to use this bathymetric survey data for the establishment of a water quality model for Boysen Reservoir.

FLOW DATA

Over time there have been several flow gauges installed in the various tributaries entering Boysen Reservoir. However, a majority of these flow gauges were installed in the early 1950s and are now defunct. There are a total of 11 tributaries entering Boysen Reservoir, most of them are ephemeral. Table 1 lists these tributaries and their ranking based on the percentage contribution of flow to Boysen Reservoir. These rankings use the results from a SWAT model developed as part of the previous water management study. Figure 1 shows the relative locations of these reaches with respect to Boysen Reservoir. Note that these percentage flow contributions are based on long-term (22 year) flow rates and consider periods when there are no flows; reach numbers correspond to the reaches delineated in the existing SWAT model. The various flow gauges were installed by the United States Geological Survey (USGS), Environmental Protection Agency (EPA), U.S. Bureau of Reclamation (BOR) and other relevant state and regional agencies.

After a rigorous effort to identify, collect and evaluate available data associated with these gauges, it was found that only one gauge is currently active (Fivemile Creek). An additional gauge (Wind River) was active as recently as 2013. All other gauges have been inactive since 1989 or earlier. Table 2 lists these gauges, their period of measurements and the related gauge ID. Figure 2 shows the location of the various gauges.

In addition to the tributary data, calculated total inflow data are available from the BOR; inflows are calculated using reservoir storage properties, measured outflows and measured water surface elevations. Furthermore, the BOR measures reservoir water surface elevations and outflow daily. These BOR data are summarized in Table 3.

WATER QUALITY DATA

The water quality study will evaluate a total of twenty (20) water quality constituents. The list was developed through consultation with WDEQ and in consideration of parameters sampled downstream of Boysen Reservoir and WDEQ WYPDES Table 2. Water quality parameters proposed for analyses include the following:

Temperature Suspended Sediment Arsenic, Total Recoverable Barium, Total Recoverable Boron, Dissolved Chloride – Technology Based Chromium, Total Fluoride, Dissolved Hardness (CaCO3) Iron, Dissolved Mercury, Dissolved Oil and Grease pH Radium 226, Total Recoverable Sodium, Dissolved Specific Conductance Sulfates Sulfide-Hydrogen Sulfide (S2-, HS-) Total Dissolved Solids Total Petroleum Hydrocarbons

An extensive review of existing data in the various tributaries for these constituents collected during the last three decades shows that data for only a few of these constituents are available. Furthermore, most of these data are limited to the Muddy Creek, Fivemile Creek and Wind River. A summary of these data is shown in Table 4. Numbers in parenthesis denotes the number of years within 1995 to 2016 (SWAT model simulation period) for which these data are available.

The available water quality data except for TDS are not sufficient to be used as input and for calibration/validation. A summary of how these data can be used for the watershed and Boysen Reservoir assessment is shown in Table 6. Note that no usable data are available for “oil & grease” and “total petroleum hydrocarbons”. Modeling will not include these parameters. However, for completeness sake two tracers will be used to represent these two parameters for future use. The water quality model will include all 20 water quality parameters (including temperature), not all will be calibrated due to lack of data. Further review of the data during the model application may suggest poor quality. In this event, water quality calibration for these parameters may not be conducted. All available data will be used as input to provide best estimates of baseline.

BOYSEN RESERVOIR MODEL

ERM owns and maintains a comprehensive hydrodynamic and water quality model, Generalized Environmental Modeling System for Surfacewaters (GEMSS®; http://gemss.com/). GEMSS is an integrated system of three-dimensional hydrodynamic and transport modules (Figure 5) embedded in a geographic information and environmental data system. GEMSS is in the public domain and has been used for hydrodynamic and water quality studies in the United States and worldwide. ERM staff contributed to the source code and have completed many applications with the GEMSS model. Organizations in the United States (Washington Department of Ecology, BOR, USGS), Korea (Ewha Womans University, National Institute of Environmental Research), Canada (Alberta Environment), Norway (Norwegian Institute for Water Research and Akvaplan-niva AS), Poland (Maritime Institute in Gdańsk) and Sweden (Royal Institute of Technology), among others, routinely use GEMSS.

Over the last decade, GEMSS has been applied to many reservoirs in the United States similar to Boysen Reservoir including Lake Powell, Lake Mead, Lake Lanier, Lake Mohave and Elephant Butte Reservoir. Additional information on the GEMSS model has been provided to the Wyoming Department of Environmental Quality (WDEQ) separately.

ERM will apply the GEMSS model to study water quality in Boysen Reservoir. GEMSS modules used for this work will include “Hydrodynamic Module -HDM” and “Water Quality Module - WQM”. The model will include the available bathymetric data (new survey conducted in 2017); inputs from the SWAT model for inflows and water quality loads; Boysen Dam specifications and Moneta Divide discharges. Surface heat exchange will be included such that appropriate seasonal and diurnal heating and cooling cycles are implemented. The model will be set up such that the entire reservoir is represented by a three-dimensional computational grid that has the ability to hindcast and forecast long term (15+ years) water quality trends. GEMSS’s three-dimensionality will ensure accurate representation of spatial and vertical variation in water quality within the Boysen Reservoir.

Figure 4 GEMSS Suite of Models

Collaborative Model Set Up

Setting up of the models will include coordination between ERM, Aethon and WDEQ. Coordinated efforts between the three entities will be conducted in order to define the applicable approach and process from inception of the modeling effort. Through a series of conference calls, representatives from each entity will work collaboratively to identify and select applicable input parameters for the modeling application. Weekly calls will be held throughout this phase. Once the model has been set up and modeling/calibration/analysis begins, calls will switch to bi-monthly (every 2 weeks) frequency. ERM will be responsible for the setting up of these calls.

Hydrodynamic Module (HDM)

GEMSS-HDM module uses 3-D computations relationships to represent horizontal and vertical momentum balance, continuity, constituent transport and the equation of state. These relationships have six unknowns (U, V, W - velocities in x, y and z directions, respectively, z’ - water surface elevation, ρ - density, Cn - constituent n) in six equations with the momentum and constituent dispersion coefficients (Ax, Ay, Az, Dx, Dy, Dz) evaluated from velocities and the

density structure. In the x and y momentum balances, the forcing terms are the barotropic or water surface slope, the baroclinic or density gravity slope, the Coriolis acceleration, the advection of momentum in each of the three coordinate directions, the dispersion of momentum in each of the coordinate directions and the specific momentum as would apply to a high velocity discharge. The baroclinic and barotropic slopes are estimated from the hydrostatic approximation to vertical momentum and horizontal differentiation of the density-pressure integral by Leibnitz' rule. The baroclinic slope is the vertical integral of the horizontal density gradient and is the major driving force for density-induced flows due to buoyancy (introduced through discharges or surface heat exchange). The vertical velocity related momentum terms are included as specific momentum to represent non-hydrostatic conditions in the module.

The vertical momentum dispersion coefficient and vertical shear is either evaluated from a Von Karman relationship modified by the local Richardson number, Ri, which is defined as the ratio of vertical buoyant acceleration to vertical momentum transfer, or through the use of higher order turbulent closure schemes. Higher order turbulence closure schemes (two equations k-ω second moment closure) within GEMSS-HDM can be used, but typically require additional calibration data for hydrodynamics. The longitudinal and lateral dispersion coefficients are scaled to the dimensions of the grid cell using the dispersion relationships developed by Okubo and modified to include the velocity gradients of the velocity field using the Smagorinsky relationship. The wind stress and bottom shear stress are computed using quadratic relationships with appropriate friction coefficients. All GEMSS modules can be run both in steady and unsteady modes through the use of boundary conditions where hydrodynamic and water quality data can be specified as constant or time varying. Currently GEMSS allows 27 different types of boundary conditions such as discharges, withdrawals, precipitation, sediment flux, bubbling, dam spillway, etc. There is no limit to the number of boundary conditions within the entire model domain including at each location.

Transport computation can be either explicit or implicit in time. It is developed so that transport coefficients can be computed once and used for all constituents during that time step at a given “n” and “k” location (“n” represents the cell location in the horizontal direction; “k” represents the cell location in the vertical direction). The solution time is not sensitive to the number of constituents being examined. Constituent computations are performed using a higher order transport QUICKEST+ULTIMATE schemes in all three directions. The model is built to accept a large number of transport constituents and constituent relationships depending on the water quality model, sediment transport model, oil and chemicals model and toxic model being used. Table 7 shows the list of processes that are important to the Boysen Reservoir modeling assessment and how these specific processes are handled within the GEMSS-HDM module.

Table 7 Key Boysen Reservoir Processes

Item #

Processes Necessary for Boysen Reservoir Modeling

Relevant GEMSS-HDM Features

1 Lateral and vertical seasonal mixing throughout Boysen Reservoir

Uses Smagorinsky relationship to represent lateral mixing. Uses Prandtl and higher order (e.g. Mellor and Yamada) turbulences schemes to represent vertical mixing.

2 Seasonal stratification in Boysen Reservoir

Uses QUICKEST or QUICKEST+ ULTIMATE higher order transport schemes to provide better prediction of constituent profiles in regions of sharp changes (e.g. stratification).

Includes complete water surface-atmospheric heat exchange processes that provides accurate representation of diurnal and seasonal variations in heat exchange and hence stratification.

3 Temporal variation in tributary inflows, reservoir outflows, reservoir water level during normal, above normal and drought water availability conditions

All forcing data (inflows, outflows, water surface elevation, meteorology, precipitation etc.) are handled in GEMSS using ASCII coded time and spatially varying input files defined by two file formats “*.hdg” and “*.wdg”. The file format “hdg” is used to input temporally varying hydrodynamic data (flows, water surface elevations, etc.). The file format “wdg” is used to input temporally varying water quality data (concentrations, loads, fluxes, etc.).

4 Turnover in Boysen Reservoir The higher order transport, vertical and horizontal mixing schemes available in GEMSS along with time varying inputs will be used to capture turn over processes in Boysen Reservoir.

5 Formation or expansion of a halocline in Boysen Reservoir and its long-term influence on stratification, mixing

Uses combination of items (1) and (2)

6 Outflows from Boysen Reservoir at different dam elevations (e.g. spillway, multiple outflow points

A series of water quality models are available within GEMSS and have been connected (active coupling) with the computationally efficient HDM module of GEMSS. Each of these water quality models offer different levels of complexity and computational framework. These water quality models cover a wide range of constituents that include dissolved oxygen, multi-algal groups, fast, slow and refractory components of particulate organic carbon, dissolved and particulates of nitrogen, phosphorous and CBOD, TSS, TDS, pH, total inorganic carbon, alkalinity, conductivity, nitrite, nitrate, ammonia inorganic phosphate, labile and refractory components of dissolved and particulate organic matter, metals, multi-macrophytes and multi-epiphytes. The inclusion of various constituents in GEMSS-WQM covers all the water quality processes and kinetics described in USCOE’s CE-QUAL-W2 and CE-QUAL-ICM models. Furthermore, all constituents relevant to the Boysen Reservoir assessment are included through combination of different models within GEMSS. The auxiliary functions for light attenuation as a function of surface solar radiation algae concentration and depth; reaeration rate as a function of wind speed and temperature; zooplankton grazing; and, relationships for sediment exchange for ammonia, nitrate nitrogen, inorganic phosphorus, and sediment-oxygen demand (SOD) have been developed from a number of field studies. These relationships, developed from field studies, are used as guidelines for applications of the water quality models to other water bodies. The water quality kinetic formulations used in GEMSS-WQM have been tested and peer reviewed by well recognized water quality professionals and agencies (e.g. U.S. EPA, U.S. Bureau of Reclamation, Washington Department of Ecology, Pennsylvania Department of Environmental Protection, Delaware River Basin Commission, etc.).

All modules of GEMSS, including water quality are linked and run simultaneously with the HDM module of GEMSS on the same computational grid. This has been found to be an important step since many short-term processes such as vertical water velocities influence short-term particle settling, and light dependent processes. Using a reasonably detailed three-dimensional grid it is possible within GEMSS to simulate the combined hydrodynamic and water quality conditions for seasonal, single and multi-year simulations. The combined framework modeling approach eliminates the need to save hydrodynamic outputs and tedious steps involved in the comparison of volumetric transport across different sections in the water quality grid and the hydrodynamic grid necessary for accuracy and correctness.

MODELING PROCEDURE

The modeling procedure will consist of three steps. The first step has already been partially completed where the SWAT based watershed model has been applied. This model will be calibrated and validated based on available flow data. Once the calibration/validation has been completed, the model will be expanded to include project defined water quality parameters. This expanded model will be validated against available WQ datasets to generate input to the reservoir model based on GEMSS. Similar calibration/validation tasks will be performed for the GEMSS model to ensure that the model predictions are in line with existing measurements. The

calibrated GEMSS model will finally be used for WQ projections based on planned Moneta Divide operations. Figure 6 shows a flow chart summarizing the proposed modeling procedure.

Figure 5 Proposed Modeling Procedure

The period of model simulation currently used in the SWAT model is 01/01/1995 to 12/31/2016, a total of 22 years. For calibration and validation purposes, the entire model simulation will be split into two distinct model simulation periods. A more detailed review of the data will identify the two periods. However, it is anticipated that neither of these periods will be less than 5 years. A similar calibration and validation split will be used for GEMSS simulations.

DATA FOR MODELLING

Based on the overview of the type of inputs, each of the model uses, and the datasets needed for calibration and validation ERM compiled a master list of the data sets. The list (an excel file Water Quality Modeling Data Sources r03.xls) was submitted to WDEQ as a separate attachment to this work plan. The master list will continue to be expanded and discussed as we engage WDEQ on review and selection of actual data during the study. The data is divided into 4 sections as detailed below:

SWAT Model o Input o Calibration/Validation

GEMSS Model o Input o Calibration/Validation

Based on data review to date, most of the data is available to run SWAT/GEMSS models. ERM will attempt to use all data available for the study. Only data that has been identified to be of poor quality will be rejected. The missing input data in both these models will be handled through the iterative calibration procedure shown in Figure 5 where missing data will be provided using a range of values that are representative for a specific constituent in the model sub-regions.

SWAT Model Calibration

Flow Calibration

About 81.5% of the total flows entering Boysen Reservoir come from Wind River and Fivemile Creek (see Table 2). Flow data available at these tributaries will be used to calibrate the majority of flow rates estimated within the SWAT model. Flow calibration will be done using SWAT- CUP (calibration and uncertainty program), a model which enable sensitivity analysis, calibration, validation and uncertainty analysis of the SWAT model. While data for other tributaries (combining for 18.5% of the total flow) are not available, BOR’s estimates of the total inflow (see Table 3) will be used to calibrate flows for the remaining tributaries. Historical gauge data available at these tributaries will be used to ensure that SWAT estimates for these remaining tributaries fall within the historically observed ranges.

The Wyoming State Water Plan by Wyoming Water Development Office (WWDO) has developed a modeling based Wind/Bighorn River Basin Water Plan1. The plan is based on spreadsheet (Microsoft Excel) based hydrologic models and uses similar datasets described

1 http://waterplan.state.wy.us/plan/bighorn/bighorn-plan.html

earlier for calibration. The results of these spreadsheet models are available and define dry and wet period flows in the various tributaries. As part of the proposed model calibration and validation exercise, results of these spreadsheet models will be used to perform qualitative comparisons with the SWAT model results.

TDS and Water Quality Calibration

Data review efforts conducted to date by ERM, indicate a lack of usable water quality data available for a rigorous water quality model calibration and validation within the various tributaries for all water quality parameters. The calibrated and validated flows from the SWAT model will be used to estimate water quality concentrations based on using the limited data as input to Boysen Reservoir. Only the upstream USGS station at Wind River (80.75% of the total inflow) consists of usable data. However, the data isn’t sufficient to be used as input as well as calibration. Therefore, the proposed work plan will directly use the water quality data for all water quality parameters as input with limited simulation of water quality within the SWAT model. However, due to SWAT’s ability to estimate natural TDS loads, TDS will be estimated through SWAT for indicative natural TDS loads. These TDS loads will be considered a baseline contributor. Further modifications to baseline TDS loads will be done during TDS validation, as described within the GEMSS Model Calibration section later.

GEMSS Model Calibration

Flow Calibration

The Boysen Reservoir model will be built using the SWAT model output as the primary input. The flow calibration for SWAT will ensure that the flow inputs for the reservoir model are correct. Further calibration for the reservoir model will be done using the BOR data (see Table 3). BOR data for outflows will be used as an input for the model, but the water surface elevation data will serve as a calibration parameter. A calibrated reservoir model will reproduce measured Boysen Reservoir water surface elevations accurately.

TDS and Water Quality Calibration

The water quality calibration for Boysen Reservoir will be conducted in conjunction with the SWAT model. Water quality loads entering Boysen Reservoir will be a key influencer of the water quality within the reservoir. Water quality parameters other than TDS will be directly used in SWAT as input from the USGS Wind River station. Baseline TDS loads (see Table 5) will be used as a starting point for the TDS calibration. The TDS loads calculated by SWAT will be used as a starting point to compare against the GEMSS computed TDS levels in Boysen Reservoir. Appropriate adjustments on the SWAT computed TDS loads will be made such that the TDS levels downstream of Boysen Dam are reproduced. These loads will be modified to reflect anthropogenic TDS contributions in addition to the natural TDS loads in different rivers.

ERM will use land-use data and qualitatively implement other known TDS sources to make these adjustments such that accurate estimates of TDS loads in the contributing rivers are made.

Remaining water quality parameters will go through a similar model calibration and validation procedure. Spatially and vertically collected data for different water quality parameters will be used to evaluate model performance. Each water quality parameter will be evaluated individually against the type of measurements available.

Once the models (SWAT and GEMSS) are able to reproduce water quality levels of all water quality parameters downstream of Boysen Dam, the combined model set up will become the existing baseline for water quality forecasting purposes (See calibration/validation feedback loop in Figure 5). Remaining water quality parameters will be calibrated only within Boysen Reservoir by comparisons to the in-reservoir and downstream data (Table 5).

Due to the lack of sufficient data, water quality parameters will only be modeled as conservative constituents, i.e., they will not experience any fate processes. Lack of fate processes will make the study more conservative as any excess water quality parameter introduced by Aethon will not reduce in concentrations due to decay, transition or transformation. The only process influencing the Aethon contribution will be dilution. In reality, these water quality parameters will experience fate processes that will further reduce their concentrations providing conservative estimates.

Input, Calibration and Validation Framework

The entire modeling framework including the use of available data for input, calibration and validation can be developed from the summary Table 6 and modeling procedure. Figure 6 shows the proposed framework for flows and Figure 7 shows the framework for water quality parameters.

EVALUATION OF MODEL PERFORMANCE

Flow and water quality constituent concentration calibration will be carried out using SWAT- CUP (calibration and uncertainty program), a model which enables sensitivity analysis, calibration, validation and uncertainty analysis of the SWAT model. SWAT-CUP uses four algorithms to evaluate model performance. The selection of appropriate algorithm for model performance will be performed during the study. SWAT-CUP calculates many model performance metrics such as 95PPU (95 % percent uncertainty which is calculated at the 2.5% and 97.5% levels of an output variable, disallowing 5 % of the very bad simulations), coefficient of determination (R2), Nash-Scutcliffe coefficient of efficiency (ENS), P-factor (% of observations covered by 95 PPU), R-factor (relative width of the 95% probability band), t-stat (measure of sensitivity) and p-value (significance of the sensitivity). The SWAT-CUP user manual suggests that P-factor value > 70% and R-factor around 1 seems to be good values for discharge. Figure 8 and Figure 9 show EPA approved values for watershed model performance.

Figure 8 Watershed Model Performance Error Values

Figure 9 Watershed Model Performance Error Values for R and R2

For Boysen Reservoir modeling using GEMSS, model performance will be evaluated using R2, ENS root mean square error (RMSE), mean error (ME), relative mean error (RME), mean absolute error (MAE) and relative mean absolute error (RMAE). The final set of model performance metrics will be identified during the course of the study since it not only depends on the model results but also on the quality of input and calibration data.

WATER QUALITY PROJECTIONS

The SWAT model currently provides hindcasting of 22 years (January 1995 to January 2017). This period of flow data is sufficient to develop projections of water quality including TDS concentrations in Boysen Reservoir under different Moneta Divide discharge scenarios. GEMSS model for water quality in Boysen Reservoir will be set up for a similar period. Once the appropriate flow and water quality loads from different tributaries entering Boysen Reservoir have been established, a baseline of all water quality constituents will be determined. This baseline will establish a quantitative estimate of the existing conditions. WDEQ is interested in minimizing the effects on this baseline due to the various Moneta Divide discharge load scenarios (100k, 150k, 250k and 350k bpd; discharge TDS of 5,000 ppm).

Once the baseline has been established, ERM will run forecast scenarios for the Moneta Divide discharge rates under a variety of conditions defined previously. A target value for each of the water quality parameter will be defined based on the acceptable level of changes in the water quality downstream of Boysen Reservoir. Maximum loads (and related concentrations) will be defined once the target Boysen Reservoir downstream concentration has been defined. For each water quality parameter a set of concentration pairs (minimum and maximum) will be estimated corresponding to individual flow scenarios. These concentration pairs will correspond to the Moneta Divide discharge concentrations that will not result in more than the defined change in the baseline. ERM, Aethon and WDEQ will discuss the selection of appropriate discharge level based on these available pairs that will form the basis of the allowable concentrations for all 20 water quality parameters.
