EXECUTIVE SUMMARY

This report provides our summary of the December 2014 Powder Mountain aquifer test, which involved pumping the Hidden Lake Well for 14 days and monitoring wells, springs and streams. The objective of the aquifer test was to determine interactions, if any, between the aquifer and spring and creek flows in Weber and Cache Counties by pumping the Hidden Lake Well. Loughlin Water Associates, LLC (Loughlin Water) prepared this report on behalf of Summit Mountain Holding Group (Summit Group).

Figure 1 shows the location of Powder Mountain. Figure 2 shows the locations of monitored points near Powder Mountain (additional points monitored by protestant’s are located several miles to the south and are not shown on Figure 2). Table 1 summarizes points monitored for the Powder Mountain aquifer test. Protestants monitored additional locations, which we plot and briefly discuss.

We performed the aquifer test during the seasonal base flow period when impacts, if any, would be most readily observable. Weather conditions were suitable and interpretable data were collected.

The pumping rate of 150 gallons per minute (gpm) used for the 14-day Powder Mountain aquifer test is far greater (by at least 25 percent) than the continuous demand that will ever be placed on the Hidden Lake Well. The Utah Division of Drinking Water (DDW, 2014) allowed the well to be equipped with a pump capable of producing up to about 180 gpm. Although the equipped rate of 180 gpm will allow operational flexibility, the DDW (2014) limited the safe yield of the well to 120.7 gpm rate. Therefore the maximum peak day indoor demand of the Equivalent Residential Connections (ERCs) and outdoor irrigation that can be supplied by the well is 120.7 gpm. Average day indoor demand will be closer to 60 gpm.

Conducting the 14-day aquifer test at a constant rate of 150 gpm allowed for careful quantitative analysis of the data and more accurate characterization of the aquifer. Previously, we used various analytical methods to estimate a transmissivity of about 500 square feet per day (ft2/day) from the 180-gpm, 24-hour pumping test of the Hidden Lake Well conducted in November 2013; see Loughlin Water (2013b and 2014a). By keeping the pumping rate constant, we were able to observe the delayed- yield response of the aquifer and revise our estimate of the transmissivity downward to about 120 ft2/day. The Utah Geological Survey (UGS, 2015a) also observed the delayed yield response and estimated a similarly low transmissivity of about 230 ft2/day.

We present a series of graphs of water levels and flow rates of the various monitored locations along with graphs of well pumping, precipitation and temperatures. We overlaid and compared the graphs to look for impacts while accounting for effects of weather.

Powder Mountain, Geertsen Creek, or other locations monitored for this study. This is not surprising because many of the monitored locations are far from the pumping well and are isolated from impacts of pumping by the presence of low permeability formations. Lefty Spring and groundwater seeps and springs on the north side of Powder Mountain discharge from the same formation as the Hidden Lake Well. However, effects of pumping the well tend to be localized with most of the produced water coming from the Weber County side of the surface water divide. Aquifer conditions that tend to confine drawdown to near the Hidden Lake Well include an aquifer of low transmissivity, faults, possibly higher vertical than horizontal permeability, and seasonal groundwater recharge.

Water in the Powder Mountain area is predominantly calcium-bicarbonate type, also with major percentage magnesium. Groundwater and surface water in quartzite terrain generally have lower dissolved solids concentrations than waters from carbonate terrain.

Evaluation of stable isotopes (oxygen-18 and deuterium) indicates that (1) waters are a mix of late autumn, winter and spring precipitation (which generally falls as snow), (2) evaporation and sublimation from the snowpack are not significant, and (3) recharge of the groundwater occurs relatively rapidly during late spring as the snowpack melts. As indicated by tritium analyses, groundwater from Lefty Spring and the Hidden Lake Well is modern (i.e. less than 10 years old). These findings are consistent with the annual cycle of groundwater level fluctuations, which also indicate strong seasonal recharge.

The UGS (2015a) stated in their presentation to the Utah Division of Water Rights (DWRi) that their evaluation of the monitoring data did not show a statistically significant influence from pumping. The UGS (2015a) also stated that the conditions for the aquifer test were satisfactory and that they doubted any significantly more relevant information would be obtained by doing another pumping test (Larsen, 2015).

The Powder Mountain aquifer test provides a basis to believe that the water under application E5382 (35-12848) can be developed without impairment of existing water rights.

The Powder Mountain aquifer test was an extensive and unprecedented testing and monitoring program. We acknowledge and appreciate the tremendous efforts and contributions of numerous participants including those of Watts Enterprises, the Summit Group, ProBuild Construction, Widdison Turbine Service (Widdison), Delco Western Company (Delco Western), Powder Mountain Ski Area, Powder Mountain Water & Sewer Improvement District (PMWSID), Wolf Creek Irrigation Company, Wolf Creek Water & Sewer District, Cascade Water Resources (Cascade), Cache County, the Weber County Engineers Office, the DWRi, the UGS, and Loughlin Water.

AQUIFER TESTING PLAN

The objective of the aquifer test was to determine interactions, if any, between pumping the Hidden Lake Well and spring and creek flows in Weber and Cache Counties.

Appendix A provides a copy of the scope of work for the aquifer test outlined by the DWRi in their letter dated November 5, 2014, the aquifer testing plan dated November 19, 2014, and several related documents. The plan called for pumping the Hidden Lake Well and monitoring precipitation, the Hidden Lake Well, Exploration Well 2, springs and streams. Table 1 summarizes points monitored for the Powder Mountain aquifer test. Figure 2 shows the locations of monitored points near Powder Mountain (additional points monitored by protestant’s are located several miles to the south and are not shown on Figure 2). All points were to be monitored for at least one week prior to pumping, during pumping, and for one week following cessation of pumping.

The Summit Group pumped the Hidden Lake Well utilizing the permanent water system pump and infrastructure. The pump was powered from the electrical grid (Rocky Mountain Power system). The pumping rate averaged 150.5 gallons per minute (gpm) for 14 days. The pumping rate was constrained by the need to maintain the pumping level a minimum of 10 feet above the pump at which point damage to the pump could occur. For protection of the pump, Delco Western programmed the system to turn the pump off at 10 feet above the pump and not allow restart until water levels rose to 50 feet above the pump.

The pumping rate of 150 gpm used for the 14-day Powder Mountain aquifer test is far greater (by at least 25 percent) than the continuous demand that will ever be placed on the Hidden Lake Well. In accordance with Utah Administrative Code (UAC) R309- 110-4 (see definition of Desired Design Discharge Rate) and R309-515-6(10)(c), the DDW (2014) allowed the well to be equipped with a pump capable of producing 180 gpm, which was the rate used in the 24-hour test conducted in November 2013 (Loughlin Water, 2014). Although the equipped rate of 180 gpm will allow flexibility in how the well is operated on a short-term basis, the DDW (2014) limited the safe yield of the well to 120.7 gpm, which, in accordance of R309-110 and R309-515-6(10)(c), is 2/3rds of the 24-hour test rate of 181 gpm. The 120.7 gpm rate will allow the Hidden Lake Well to supply the peak day indoor demand of up to about 215 ERCs. In UAC R309-510-7(1), the DDW (2009) sets (1) the indoor peak day demand for indoor use at 800 gallons per day (gpd) per ERC, which is about 0.56 gpm, if pumped on a continuous 24-hour-per-day basis. The average yearly demand of an ERC is one half the peak day demand or 400 gpd, which is about 0.28 gpm if pumped on a continuous basis. Therefore, the actual long-term continuous demand placed on the Hidden Lake Well will be closer to 60 gpm. Any outdoor irrigation would reduce the number of indoor ERCs that could be supplied by the well and could increase the average yearly demand somewhat, but the maximum peak day demand would remain unchanged at 120.7 gpm.

Based on pump performance and water levels during the test, we decided not to increase the pumping rate during the later stages of the test from the initial 150 gpm

Loughlin Water Associates LLC Page 7 of 24 March 27, 2014

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

rate because: (1) water levels in the well continued to fall, (2) water level plotted on a semi-log graph showed a steepening trend, (3) continuing at a constant pumping rate allowed for quantitative analysis of the data and a more accurate characterization of aquifer response to pumping, (4) increasing the rate could have caused a significant water level drop and have required a subsequent reduction in rate, and (5) the additional amount of water that could have been pumped was small. We obtained excellent data that can be used to assess the impacts of pumping and evaluate aquifer properties.

During the pumping period, we provided the State Engineer, protestants and other interested parties with an approximately daily e-mail that included pumping rate, gallons pumped since previous day’s report, water level in Hidden Lake Well, problems encountered and actions taken, and changes, if any, planned for the pumping program. We provided monitoring data to the State Engineer and others on a weekly basis during the testing period.

In accordance with the plan, we provided this written report to the State Engineer that summarizes the collected data and our analysis and assumptions.

HYDROGEOLOGY

The hydrogeology of the Powder Mountain area is described in a number of published and unpublished reports including King (2004), Loughlin Water (2013a and 2014a). The following provides a very brief summary of the hydrogeology of Powder Mountain. Figure 3 provides a geologic map. Figure 4 summarizes the stratigraphy of the area, rock formations and formation symbols. Figures 5A through 5D provide geologic cross sections. Please refer to documents listed in the References section herein and other materials for more detailed information.

Powder Mountain straddles a high ridge that forms the drainage divide between the Ogden River drainage system (to the south) and the Bear River drainage system (to the north), as shown on Figure 1. The divide also is the boundary between Weber County (to the south) and Cache County (to the north).

Bedrock in the Powder Mountain area is composed of highly deformed Paleozoic and Precambrian sedimentary and metamorphic rocks. These rocks have been chopped up by low-angle thrust faults and squeezed into large folds, including the Powder Mountain syncline that plunges (dives) to the north, toward Cache Valley, at about 10 to 30 degrees. These very ancient rocks are covered in places with up to more than 1000 feet of the Tertiary-age Wasatch Formation.

Uplift and erosion have left mountains, wide valleys and narrow canyons. Thin soils cover the mountain slopes and thin alluvial deposits occur in the bottom of mountain canyons. Relatively thick unconsolidated valley-fill deposits underlie Ogden Valley.

Paleozoic and older limestone and dolomite (carbonate) rocks and, to a lesser degree, quartzite rocks are the primary aquifers and potential sources of groundwater for Powder Mountain. The Tertiary Wasatch Formation and thin Quaternary

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

unconsolidated deposits are present at the ground surface over much of the area but are not considered to be significant aquifers. The Paleozoic and older shale and similar low-permeability rock are considered to be aquitards (confining layers). The aquitards divide the aquifers into separate stratigraphic groundwater compartments (King, 2004).

Groundwater in the Powder Mountain vicinity is recharged primarily from infiltration of snowmelt. Recharge moves vertically downward though aquifers and aquitards and laterally along higher permeability strata. Although locally unsaturated, the Wasatch Formation is believed to accept considerable recharge and to transmit groundwater to deeper formations. Along with several springs, infiltration of precipitation in soils and the more permeable near-surface rock in canyon slopes eventually discharges to provide base flow of streams.

MONITORING DATA AND EVALUATION

Table 1 summarizes the monitoring program for the aquifer test at Powder Mountain. Figure 2 shows the locations of the Hidden Lake Well and monitoring points at Powder Mountain (several additional points monitored by protestants are located several miles to the south and are not shown on Figure 2).

HIDDEN LAKE WELL

Aquifer Test Pumping

The Summit Group pumped the Hidden Lake Well from December 2 through December 16, 2014, for the Powder Mountain aquifer test. The test utilized the water system components including permanent pump, well water level transducer, flow meter, water tank and piping. Widdison personnel monitored and adjusted the pumping rate. Widdison personnel manually recorded water level in the Hidden Lake Well (displayed as feet above the pump), pumping rate (displayed as gpm and as total gallons), water tank level and pressure in piping displayed in the pump house. Appendix B provides copies of aquifer pumping test data sheets.

In addition, water level (as feet above the pump) in the Hidden Lake Well and pumping rate (as gpm) were recorded every 5 minutes utilizing a data recorder provide by Delco Western.

The pumping rate held very steady with a few adjustments of the system valve in the pump house. Only one (4-minute) pump stoppage occurred. On December 8, 2014, at approximately 8:36 am the pump shut off (apparently a worker accidentally tripped an electrical switch). Widdison staff restarted the pump at about 8:40 am. The total volume of water pumped during the 14-day period was 3,033,700 gallons (average of 150.5 gpm or 216,700 gallons per day).

Prior to the aquifer test, the Summit Group commissioned further development of the Hidden Lake Well using a dual swab and pumping system to remove fine sand and

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

reduce turbidity. Detailed discussion of the development work and monitoring are provided in Loughlin Water (2014b). Widdison began development operations on August 21, 2014 and completed development on September 29, 2014. On October 2, Widdison brought in a small rig and bailed the well to remove sand that accumulated in the bottom of the well from development operations. The volume of water pumped between August 21 and September 29, 2014 (a 39-day period), was approximately 526,900 gallons.

On November 25, 2014, Summit Group pumped the Hidden Lake Well for about 140 minutes under generator power to test the pump and system (shakedown pumping). About 18,000 gallons were pumped.

Figure 6 provides a graph of daily pumping rate versus time during the aquifer test and during pre-test and post-test periods. The date (x) axis of the graph on Figure 6 is at the same scale as many other graphs herein, which facilitates comparison of information among the graphs.

Figure 7 shows a graph of water levels in the Hidden Lake Well from July 23, 2014 to January 3, 2015. The date (x) axis is the same as many other graphs herein, which facilitates comparison of information among the graphs. Table 2 lists water levels measured by hand in the Hidden Lake Well with a wire sounder during 2014.

Appendix C presents time-drawdown plots for the Hidden Lake Well and Exploration Well 2 during the Powder Mountain aquifer test. Semi-log plots show a gradual steeping of the drawdown curve during the later part of the test that is suggestive of the cone of depression encountering an aquifer barrier; however, graphical analysis using log-log plots indicates that delayed gravity drainage affected the drawdown curve and not aquifer boundaries. Delayed gravity drainage occurs under unconfined aquifer conditions and is the short-term downward flow of groundwater that occurs when the water table drops. Delayed gravity drainage temporarily decreases the slope of the drawdown curve. Eventually water finishes draining from above and the drawdown resumes a curve representative of aquifer conditions without the temporary drainage. We noted delayed gravity drainage in our analysis of the Hidden Lake Well pumping test conducted November 2013 (Loughlin Water, 2014a). Appendix C provides further discussion.

Water Discharge During Aquifer Test

During the aquifer test, the Hidden Lake Well pumped water through the well house to the 415,000-gallon water tank, except for the first 20 minutes during which water was pumped to waste (pumped to the concrete box and pump-to-waste ditch system). Pump-to-waste is a normal feature of a public water well system that provides for initial discharge of water that is turbid and/or sandy.

From the 415,000-gallon tank, water flowed through the recently constructed subsurface water piping system to a fire hydrant located as shown on Figure 2. From the fire hydrant water flowed over a half mile through temporary flexible hose to the bottom of the slope in Lefty Canyon as shown on Figure 2.

Loughlin Water Associates LLC Page 10 of 24 March 27, 2014

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

During the 14-day pumping period, leaks occurred (and were repaired) in the flexible hose that transported water from the hydrant to the bottom of Lefty Canyon. One or more persons, including Kalem Minor, John (JB) Brown, and Miranda Menzies walked the discharge line on a near daily basis. The leaks occurred mostly near several areas referred to as Point A, Point B and Point C (shown on Figure 2). Near Point A, leaks from pin holes occurred in an abraded section of line, probably caused by rubbing against trees. At Points B and C, leaks probably occurred due to the pressure in the line and line movement caused by surging discharge. Leaks were repaired the same day that they were discovered or the next day if repair materials needed to be procured.

Kalem Minor fixed the leaks in the flexible pipe by turning the water off at the hydrant (the 415,000-gallon tank temporarily stored water pumped from the well), and then replacing damaged sections of pipe or couplings.

The leaks did not affect the aquifer test. The upper leaks (near Point A on Figure 2) were small (2-3 gpm) from pin holes and coated nearby vegetation and ground with ice. The larger leaks occurred near the bottom of the canyon (near Points B and C) where the Calls Fort Shale Member (Cbc), which is an aquitard, separates the Nounan Formation (Cn) from the Middle Member of the Bloomington Formation (Cbm). Mass movement (Qm) deposits derived from the Wasatch Formation (Tw) cover bedrock along the water line. The Wasatch Formation and mass movement deposits have relatively low permeability. In addition, aquifer pressure heads in the Nounan Formation would have been above the land surface in this area; therefore, surface water would not infiltrate into the Nounan Formation along the lower part of water line. Figure 3 (Geologic Map), Figure 4 (Stratigraphic Column) and Figures 5A through 5D (Geologic Cross Sections) herein summarize hydrogeologic information. We provided additional details concerning the leaks and geohydrologic conditions in our letter dated December 11, 2014, responding to the letter from Mr. Steven Vuyovich of Holland & Hart LLP dated December 10, 2014.

EXPLORATION WELL 2

National EWP (the drilling contractor) installed a vibrating wire piezometer (VWP) with data logger in the 2-inch diameter standpipe in Exploration Well 2 in 2013 to monitor water pressures/levels in Exploration Well 2.

On October 17, 2014, the site contractor modified the Hidden Lake Well and Exploration Well 2 in order to place the well heads below grade to facilitate snow plowing of the area. Loughlin Water staff and the site contractor pulled the VWP transducer from Exploration Well 2, which was at the bottom of a 1400-foot long electrical cable in the standpipe. We measured water level depths in the two wells using a conventional wire sounder. The water level was 734.90 feet in the Hidden Lake Well and 735.32 feet in Exploration Well 2 (depths based on top of manhole). Static water levels measured with a conventional wire sounder in the Hidden Lake Well and in Exploration Well 2 in 2014 were up to about 6 feet higher than reported by the VWP transducer. The discrepancy may have been related to measurement difference related to borehole drift (measurement of length at the angle of the well versus vertical water

Loughlin Water Associates LLC Page 11 of 24 March 27, 2014

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

pressure), instrument precision, long-term instrument drift, the difference in water density versus assumed density, or other factors. On November 7, 2014, we removed the VWP transducer apparatus and temporarily replaced it with a new pressure transducer (Troll 700) for the pumping test. On January 7, 2015, we removed the Troll 700, measured the water level with a wire sounder, and replaced it with the VWP transducer. Table 3 lists manual water level measurements made with a wire sounder.

Figure 8 shows a graph of water levels in Exploration Well 2 from September 9, 2013, to January 7, 2015 as reported by the VWP and Troll 700. Although water levels reported by the VWP transducer in Exploration Well 2 in 2014 are lower than water levels measured by hand with a conventional wire sounder, the data reflect water level trends. Exploration Well 2 is located about 25 feet from the Hidden Lake Well. Figure 8 shows that water levels were falling at a rate of about 0.2 feet per day in September and early October 2013, prior to development and test pumping of the Hidden Lake Well. Pumping for development and testing occurred in October and November 2013. During autumn-winter-early spring 2013-2014, water levels in Exploration Well 2 fell slowly and steadily (following recovery from the pumping test) to a maximum depth of about 784 feet on April 21, 2014. Water levels rose from April 21, 2014 to May 5, 2014.

Unfortunately, on May 5, 2014, one of our staff inadvertently set the data logger to record every 60 seconds instead of every 60 minutes and data collected between May 5 and June 7, 2014, were over-written because of the large amount of data collected. Water levels continued to rise and peaked around July 23, 2014, at a depth of about 721 feet. A falling background water level trend is evident in the subsequent months.

Figure 8 illustrates the annual water level cycle and the effects of aquifer recharge and discharge. Figure 8 also shows the effect of pumping the Hidden Lake Well imposed on the annual background water level cycle. Following recovery of drawdown from pumping the Hidden Lake Well, water levels returned to the pre-pumping background trend. The graph indicates that pumping did not affect background aquifer water level trends following recovery.

Figure 9 shows a graph of water levels in Exploration Well 2 from July 23, 2014 to January 7, 2015. The date (x) axis is the same as many other graphs herein, which facilitates comparison of information among the graphs.

PRECIPITATION AND SNOWPACK

On November 7, 2014, we installed a precipitation gage near the maintenance building at Powder Mountain (see Figure 2 for location). We also obtained precipitation and snow pack data for climate stations in the Powder Mountain region from the National Resources Conservation Service (NRCS) snow telemetry (SNOTEL) system, from the Utah Climate Center (UCC) and from the MesoWest system. Table 4 lists the stations and shows their locations. We provide data from seven stations in the area because precipitation varies from place-to-place and with elevation. The data indicate climate patterns and are a good indicator of precipitation at Powder Mountain.

Loughlin Water Associates LLC Page 12 of 24 March 27, 2014

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

A water year begins on October 1 and extends through September 30 of the following year. Precipitation and snow pack data for a water year provide a better metric for evaluating runoff and aquifer recharge than precipitation for a calendar year. Table 5 compares precipitation during the 2012-2013 water year and the 2013-2014 water year with average annual precipitation. Figure 10 graphs cumulative precipitation for the past two water years. Water year 2012-2013 was very dry with total precipitation about 70 percent of normal. Water year 2013-2014 precipitation was near average, about 97 percent of normal.

Figure 11 is a graph of the amount of snow on the ground as snow water equivalent (SWE) for the past two water years and the start of the new water year. Snow accumulations in the winter of 2013-2014 were greater than in the winter 2012-2013, and were much higher at higher elevations (as indicated by snow water equivalent at the Ben Lomond Peak station). Spring snowmelt provides the primary source of aquifer recharge at Powder Mountain (compare the time of snowmelt with the rise of water levels in Exploration Well 2 on Figure 8).

Figure 12 graphs daily precipitation from July 23, 2014, to January 7, 2015, at the regional climate stations. The graph can be used to identify days when precipitation probably occurred at Powder Mountain that might have affected stream flow, spring flow or groundwater levels.

Table 6 lists daily precipitation during November and December 2014 recorded at the climate stations and the Powder Mountain temporary precipitation gage. Table 6 also lists snow depth reported at the MesoWest Powder Mountain UTPM2 gage. The gage is located about 2000 feet northeast of the Hidden Lake Well on the north side of the Powder Mountain ridge. The MesoWest UTPM2 gage operates during the winter season and provides hourly data; the gage also reports hourly precipitation but the data do not appear to be reliable and are not listed in Table 6.

During November and December 2014, precipitation at Powder Mountain fell mainly as snow and therefore would not have readily runoff to streams. Daily temperatures varied considerably during November and December 2014; temperatures recorded by the barometric transducer devices at Lefty Spring and at the Wellsville Middle Fork weir show temperature variations. In general, temperatures were higher on the south- facing location of Lefty Spring than on the north-facing location of the Wellsville Middle Fork weir.

LEFTY SPRING

Powder Mountain installed a 90° V-notch weir in Lefty Spring. Lefty Spring issues from bedrock a few feet above the pool created by the weir.

Table 7 summarizes manual measurements at Lefty Spring during 2014. We measured the depth of water (1) at the v-notch and (2) in the pool upstream of the weir using a staff gage. Because (1) drawdown occurs at the v-notch, (2) flow through the v-notch sometimes pulses and (3) the ruler placed in the flow through the v-notch affects the

Loughlin Water Associates LLC Page 13 of 24 March 27, 2014

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

reading, the staff gage in the pool provides the best measurement of head (H) for estimating the flow rate at the weir.

We also measured flow rate using the volumetric (“bucket and stopwatch”) method. These flow rate measurements are imprecise because of the rather small space in which to insert a bucket, the small bucket size and short time interval to fill the bucket. We generally filled the bucket multiple times and used the total time and total volume to calculate the flow rate listed in Table 7. While imprecise, the volumetric measurements generally agree with flow rates calculated using the weir water level data (manual and transducer measurements).

Figure 13 plots pressure and temperature measurements made by water pressure and barometric pressure transducers at Lefty Spring supplied by Loughlin Water. Our water pressure transducer was a small, unvented device that sat completely below the water surface; therefore, temperature measured by the device was representative of water temperatures. The barometric transducer device also recorded temperature, which would be representative of air temperature. Figure 13 shows “raw” data plots; to obtain a depth of water reading, we subtracted barometric pressure from water pressure.

Protestants installed and operated a barometric pressure transducer and three water pressure transducers at Lefty Spring as shown on Figure 14. A list on Figure 14 summarizes our understanding of when the protestant devices were used to monitor Lefty Spring and Lefty Stream (called “Lower Lefty” by protestants). Two of the water pressure devices were vented and one device was unvented (see list on Figure 14). The water pressure transducer devices were not fully submerged and temperatures recorded by the devices are not representative of water temperature. The BaroMerge #386828 plot is the water pressure reported by the protestants after subtracting barometric pressure from the pressure recorded by the unvented water pressure transducer.

The weir water level (H) is the height of water in the pool above the elevation of the bottom of the v-notch. Figure 15 plots the weir water level (H) measured by the transducer and with the staff gage. To plot H using the transducer data, we (1) subtracted the barometric pressure from each water pressure reading and (2) subtracted 0.37 feet from each reading, to account for the depth of the transducer below the v-notch. Note that the changes in water level are quite small; to illustrate this, we placed a photograph of a quarter (about 0.08 feet in height) at same scale as the water level scale (y-axis) on Figure 15.

On Figure 15, we also plotted water levels recorded by the protestant’s non-vented transducer (no corrections applied). These water levels show small changes that do not always agree with the manual measurements or our transducer measurements.

Figure 16 shows (1) the estimated flow rate from Lefty Spring based on our calibrated transducer data (shown on Figure 15), (2) estimated flow rate calculated from manual weir water levels (calibrated staff gage measurements shown on Figure 15 and listed in Table 7), and (3) bucket and stopwatch flow measurements (listed in Table 7).

Water levels shown on Figure 15 and estimated flow rates shown on Figure 16 show no discernible response to the pumping of the Hidden Lake Well. Figure 6 shows the dates and volumes of water pumped from the Hidden Lake Well. Overlay Figure 6 on Figures 15 and 16 to compare spring flow with time/volume of pumping. Water levels and flow rate may show a slight response to precipitation but the response, if any, is small and indistinct. Overlay Figure 12 (daily precipitation) on Figures 15 and 16 to facilitate evaluation.

LEFTY STREAM

The protestants installed a 90° v-notch weir in the stream about 100 feet below Lefty Spring on November 21, 2014. The protestants refer to the weir as “Lower Lefty” and we refer to the weir as “Lefty Stream”. We measured the depth of water (1) at the v- notch and (2) in the pool upstream of the weir using a staff gage. The staff gage in the pool provides the best measurement of head (H) for estimating the flow rate at the weir. The protestants installed a second staff gage in early December but primarily report manual readings in the v-notch. Table 8 summarizes manual measurements at Lefty Spring during 2014.

Figure 17 graphs pressure and temperature measurements made by our water pressure transducer at Lefty Stream and our (Lefty Spring) barometric pressure transducer. Our water pressure transducer was a small, unvented device that sat completely below the water surface; therefore, temperature measured by the device was representative of water temperatures. The barometric transducer device also recorded temperature, which would be representative of air temperature. Figure 17 shows “raw” data plots; to obtain a depth of water reading, barometric pressure was subtracted from water pressure.

Protestants installed and operated a barometric pressure transducer (at Lefty Spring) and two water pressure transducers at the Lefty Stream weir as shown on Figure 18. A list on Figure 18 summarizes our understanding of when the devices were used to monitor Lefty Spring and Lefty Stream (called “Lower Lefty” by protestants). One of the water pressure devices was vented and one device was unvented (see list on Figure 18). The vented water pressure transducer device appears to have been sufficiently submerged to record representative water temperatures. The BaroMerge #386828 plot is the water pressure reported by the protestants after subtracting barometric pressure from the pressure recorded by the unvented water pressure transducer.

The weir water level (H) is the height of water in the pool above the elevation of the bottom of the v-notch. Figure 19 graphs the weir water level (H) measured by the transducer, with the staff gages and in the v-notch. To plot H using our water level transducer data, we (1) subtracted the barometric pressure from each water pressure reading and (2) subtracted 0.14 feet from each reading, to account for the depth of the transducer below the v-notch. To plot H using the protestant’s vented water level transducer data, we subtracted 0.29 feet from each reading, to account for the depth of the transducer below the v-notch. Note that the changes in water level are quite small.

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

Figure 20 shows the estimated flow rate at Lefty Stream based on (1) the transducer data and (2) manual weir water levels (listed in Table 8).

The water levels shown on Figure 19 and the estimated flow rates shown on Figure 20 show a rising trend from the start of monitoring by protestants on November 26 to November 29, then a dropping trend that began to level out around December 18, 2014, and continued until at least January 30, 2015 (protestant continued to monitor Lefty Stream). Manual measurements generally reflect these trends although there is considerable scatter in the data. Hidden Lake Well pumping began the evening of December 2 and continued until the evening of December 16, 2015. Although one might be tempted to attribute the flattening of the trend to cessation of pumping at the Hidden Lake Well, note that water levels were rising and falling before the start of pumping. Flow and water levels in the weir may have been affected by precipitation and snowmelt. Note that according to the Powder Mountain temporary gage, 1.2 inches of precipitation occurred November 24, 0.53 inches occurred on November 30- December 1, 0.62 inches occurred on December 14-15, and precipitation occurred each day from December 20-23 and probably continued through the end of December 2014. The record is short from which to determine effects of precipitation, snowmelt, infiltration from shallow soils, and localized runoff on the Lefty Stream weir.

PIZZEL SPRING #3

Pizzel Spring #3 discharges into a spring box in Pump House #1. There are two pumps and three water meters at Pump House #1 (meter #1 [“main pump”], meter #2 [“2nd pump”], and a meter on the overflow installed by Wolf Creek Irrigation personnel in August 2014). The three meters belong to PMWSID. Reported total flow from Pump House #1 is the sum of the three meters. Because the three meters do not have the same accuracy, the “total flow” varies depending on which pumps are operating. Totalizing meter readings were manually recorded daily to every few days from August 19, 2014 to January 7, 2015. Reported flow in gallons per minute (gpm) is the average between totalizing meter readings. PMWSID sometimes operates one or more pumps only during the day and sometimes operates the pumps day and night. PMWSID pumped mostly using the “main” pump (meter 1); if operated day and night, the average daily pumping rate would be about twice that if operated half of the day.

Pump House #1 (the lowermost pump house) pumps to Pump House #2 from which water is pumped to system water tanks. Pizzel Spring #2 discharges into the system at Pump House #2 but the recent flow rate was tiny (less than 0.2 gpm). There is a water meter in Pump House #2 (Meter A) that measures combined flow of water from the Pizzel Spring #2 and water pumped from Pump House #1.

Table 9 summarizes meter readings recorded on the data sheets in Pump House #1 and the calculated total average flow rate from Pizzel Spring #3. Appendix D provides copies of the totalizer data sheets. Protestants also recorded totalizer readings and spot measurements from the three Pump House #1 meters and the Meter A in Pump House #2. Protestants apparently performed spot measurements of discharge rate using a watch and the totalizing meters. Appendix D provides listings from protestants of these measurements.

Loughlin Water Associates LLC Page 16 of 24 March 27, 2014

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

Figure 21 plots average flow calculated using the first reading each day from the three meters at Pump House #1 and the total of the three meters. Figure 22 plots (1) the sum of Meter #1 and #2 flow and (2) flow rate from Meter A in Pump House #2. The sum of Meter #1 and #2 should be essentially the same as Meter A in Pump House #2.

As indicated by Figure 21, the main pump (meter #1) pumped an average of about 9 to 18 gpm each day from late August to December 23, 2014 (Pump #1 pumps at a rate of about 18 gpm but if it runs only for a half day, the average rate is 9 gpm). The second pump (Meter #2) was utilized in addition to the main pump from about September 5 to September 10 and from October 28 to November 10. Note that when the second pump runs, the calculated total flow increases. This discrepancy appears to be due to an inaccurate meter, probably Meter #2.

As indicated by Figure 22, the flow measured by Meter A in Pump House #2 was about equal to the sum of Meters #1 and #2 when Pump #2 was not running. When Pump #2 was running, the sum of Meters #1 and #2 was much greater than Meter A. This indicates that Meter #2 is inaccurate.

Bucket and stop watch measurements of the overflow rate in late November indicated that the overflow meter under-reported actual flow. We thought that the meter might be reading low because the meter pipe was not full. Wolf Creek Irrigation personnel added an elbow to the discharge to keep the pipe full, but the meter continued to read low.

On December 24, 2014, PMWSID turned on both the main and 2nd pump; overflow ceased and the calculated total flow (the sum of the three Pump House #1 meters) from Pizzel Spring #3 “increased” from about 25 gpm to 35 gpm (the “increase” is actually the result of inaccuracies of the meters – Meter 2 appears to read high compared to Meter 1). The rate pumped from Pump House #1 increased from about 9 gpm on December 23 to about 30 gpm on December 24, 2014, based on Meter #1 plus Meter #2. The meter in Pump House #2 indicated an increase from 9 to 13 gpm (compared with an increase from 9 to 30 gpm using Pump House #1 meters). When only the main pump in Pump House #1 was operating, meter #1 agreed quite closely with the meter in Pump House #2).

From about November 10 to December 23, 2014, Pump #1 operated quite consistently and Pump #2 was off. Despite the issues with the data and the absolute accuracy of the meters, the data appear useable for indicating a potential impact from pumping the Hidden Lake Well. The data indicate that pumping the Hidden Lake Well did not impact Pizzel Spring #3.

WELLSVILLE MIDDLE FORK

The protestant’s placed a 90° v-notch weir in a stream channel north of the Hidden Lake Express ski lift base (see Figure 2 for location). We refer to this location as Wellsville Middle Fork but some refer to it as the Hidden Lake Weir. We installed a staff gage on September 15, 2014. The valley bottom is rather wide in this area. In the

Loughlin Water Associates LLC Page 17 of 24 March 27, 2014

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

vicinity, groundwater rises from unconsolidated deposits in the valley bottom and to a lesser extent from seeps on side slopes. Precipitation and snowmelt over the valley bottom would contribute to flow through the weir.

Table 10 summarizes manual measurements of the height of water (1) directly above the bottom of the v-notch and (2) in the pool upstream of the weir using a staff gage.

Figure 23 graphs pressure and temperature measurements made by water pressure and barometric pressure transducers at the Wellsville Middle Fork Weir supplied by Loughlin Water. Our water pressure transducer was a small, unvented device that sat completely below the water surface; therefore, temperature measured by the device was representative of water temperatures. The barometric transducer device also recorded temperature, which would be representative of air temperature. Figure 23 shows “raw” data plots; to obtain a depth of water reading, we subtracted barometric pressure from water pressure.

Figure 24 graphs water levels recorded by the protestant’s vented transducer. We subtracted 0.33 feet from each reading to account for the depth of the transducer below the v-notch. The water pressure transducer was not fully submerged and temperatures recorded by the device were not likely representative of water temperature.

The weir water level (H) is the height of water in the pool above the elevation of the bottom of the v-notch. Figure 24 graphs the weir water level (H) measured by the transducer and with the staff gage. To plot H using our transducer data, we (1) subtracted the barometric pressure from each water pressure reading and (2) subtracted 0.15 feet from each reading, to account for the depth of the transducer below the v-notch.

Figure 25 shows the estimated flow rate through the weir based on the manual staff gage measurements and the calibrated transducer data.

Water levels shown on Figure 24 and flow rates shown on Figure 25 indicate no discernible response to the pumping of the Hidden Lake Well. Figure 6 shows the dates and volumes of water pumped from the Hidden Lake Well. Overlay Figure 6 on Figure 24 or Figure 25 to compare water levels and weir flow with time/volume of pumping. Water levels (and flow) appear to respond to precipitation. Overlay Figure 12 (daily precipitation) on Figure 24 or Figure 25 to facilitate evaluation. The small daily fluctuations during summer and autumn may be a response to evapotranspiration. The large fluctuations on September 27 and 28, 2014 may indicate disturbance of the transducer or water pool (perhaps by cattle or other animals) but more likely were caused by high precipitation.

WELLSVILLE CREEK NEAR NORTH BOUNDARY OF POWDER MOUNTAIN

The State Engineer’s office placed a Cipolletti Weir in Wellsville Creek near the north boundary of the Powder Mountain property (see Figure 2) in August 2014. We installed

Loughlin Water Associates LLC Page 18 of 24 March 27, 2014

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

a staff gage on September 15 and installed a non-vented transducer at the weir on November 4, 2014.

Table 11 summarizes manual measurements of the height of water (1) directly above the bottom of the weir opening and (2) in the pool upstream of the weir using a staff gage.

Figure 26 graphs water pressure and temperature recorded by the transducer in the pool of the North Boundary Weir and temperature and barometric pressure from the barometric transducer (Northside Barometer) at the Wellsville Middle Fork Weir. Our water pressure transducer was a small, unvented device that set completely below the water surface; therefore, temperature measured by the device was representative of water temperatures. Figure 26 shows “raw” data plots; to obtain a depth of water reading, barometric pressure was subtracted from water pressure.

The weir water level (H) is the height of water in the pool above the elevation of the bottom of the v-notch. Figure 27 graphs the weir water level (H) measured by the transducer and with the staff gage. To plot H using our transducer data, we (1) subtracted the barometric pressure from each water pressure reading and (2) subtracted 1.74 feet from each reading, to account for the depth of the transducer below the bottom of weir opening and the barometric pressure difference between the weir and the barometer locations.

Figure 28 shows the estimated flow rate through the weir based on the manual staff gage measurements and the calibrated transducer data.

Water levels exhibited a series of large, short-term rise-and-fall in water level and flow at regular intervals as shown on Figures 27 and 28. Short-term rise-and-fall in water level (and flow) occurred over periods of 2 to 3 hours (occasionally longer), every 3 to 4 days and at different times of the day. The UGS commented that they also observed these spikes in their data. Evan Miller (personal communication, 2015) of PMWSID said that he has observed water flow increases accompanied by bubbles in the east fork of Wellsville Creek. Evan thought that the water and bubbles resulted from a release of water in the aquifer that was temporarily air-locked. Pulsing springs are known to exist in the region.

Water levels shown on Figure 27 and flow rates shown on Figure 28 indicate no discernible response to the pumping of the Hidden Lake Well. Figure 6 shows the dates and volumes of water pumped from the Hidden Lake Well. Overlay Figure 6 on Figure 27 or Figure 28 to compare water levels and weir flow with time/volume of pumping. Water levels (and flow) appear to respond to precipitation and temperature. Overlay Figure 12 (daily precipitation) on Figure 27 or Figure 28 to facilitate evaluation.

GEERTSEN CREEK (BAR B FLUMES)

Bar B Ranch installed two flumes with ultrasonic water level readers on their property: (1) the Lower Flume, which is in Geertsen Creek and (2) the Upper Flume, which is in

Loughlin Water Associates LLC Page 19 of 24 March 27, 2014

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

a ditch that diverts water from Geertsen Creek. The ultrasonic water level readers hang over the flumes and measure water level from above the water surface.

Figure 29 plots the flow rate reported in spreadsheets provided by the protestants. During the period on the plot, there was no flow in the Lower Flume except from about August 18 to September 15, 2014. During that period, water was diverted into Geertsen Creek from the Causey Ditch. Plotted flow through the Upper Flume generally decreased from late July through September, and was relatively steady October through December 2014. The small spikes in flow around September 28 and October 1 coincide with high precipitation events. The apparent increased flow during mid-November and during late December 2014 coincided with periods of very cold temperatures. The apparent increased flow was likely not real but due to erroneous readings caused by ice and snow in the flume (although significant precipitation did occur during these periods).

The data indicate that pumping the Hidden Lake Well did not impact Geertsen Creek.

OTHER PROTESTANT MONITORING POINTS

The protestants provided additional monitoring data to us for the following sites: Browning Bar B Well, Highlands Well, and Burnett Springs. We plotted the data on Figures 30 through 32. The plots show no discernible response to the pumping of the Hidden Lake Well.

The protestants also installed a 3-foot wide rectangular weir with end contractions in lower Wolf Creek. Protestants manually measured depth to water in the mouth of the weir. Note that the Hidden Lake Well discharged to the Wolf Creek drainage about three miles upstream of the weir. We plotted the water depth measurements on Figure 33. Flow through the weir was about 940 to 1270 gpm (depth of 4.3 to 5.3 inches). Of course, pumping the Hidden Lake Well showed no negative impacts on flow at the weir.

WATER CHEMISTRY AND STABLE ISOTOPES

In 2013 and 2014, Loughlin Water collected water samples for general chemistry analyses from 16 sites at Powder Mountain. The samples were collected from springs, streams and the Hidden Lake Well. In 2014, we collected eight water samples for analysis of oxygen-18 and deuterium (stable isotopes). We also collected water samples for tritium from the Hidden Lake Well and Lefty Spring. The memorandum in Appendix E provides detailed discussions of the samples, analyses, results and interpretations.

Water in the Powder Mountain area is predominantly calcium-bicarbonate type, also with a major percentage magnesium. Water samples collected from Exploration Well #1 in 2013 had higher concentrations of sodium but calcium and bicarbonate ions were the dominant ions, and with major percentages of magnesium. The water sample from Pizzel Spring #3 contained higher sodium and chloride concentrations, although

Loughlin Water Associates LLC Page 20 of 24 March 27, 2014

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

percentages of calcium, magnesium bicarbonate were greater than sodium and chloride.

Water in the Powder Mountain area is slightly depleted in heavier isotopes of oxygen (oxygen-18) and hydrogen (deuterium), but plots near the global mean meteoric water line (GMWL). This information conforms to the view that groundwater in the area is a mix of late fall, winter and spring precipitation, which generally falls as snow. Evaporation and sublimation from the snowpack occurs, but is not significant. Recharge of the groundwater occurs relatively rapidly during late spring as the snowpack melts.

Groundwater from Lefty Spring and the Hidden Lake Well is modern (i.e. less than 10 years old) as indicated by the tritium concentrations in water samples collected from the two sources. Older groundwater likely exists in the Powder Mountain area.

UGS DATA

The UGS conducted a program of water sampling, stream/spring flow measurements, hydrogeological reconnaissance, and evaluation of data collected by participants in the Powder Mountain aquifer test. The UGS analyzed water samples for total dissolved solids (TDS), selected major chemical constituents and oxygen-18 and deuterium (stable isotopes). Appendix F provides copies of the UGS data released a preliminary summary in January 2015. We added a sample location map to Appendix F.

The UGS presented their preliminary findings to the DWRi in January 2015. PowerPoint slides of the presentation can be found on the UGS webpage: http://geology.utah.gov/geologic-resources/data-databases/#tab-id-3

The UGS stated that the work presented was preliminary and had not undergone rigorous review.

CONCLUSIONS

The pumping rate of 150 gpm used for the 14-day Powder Mountain aquifer test is far greater (by at least 25 percent) than the continuous demand that will ever be placed on the Hidden Lake Well. Although the equipped rate of 180 gpm will allow operational flexibility, the DDW (2014) limited the safe yield of the well to 120.7 gpm rate. Therefore the maximum peak day that can be supplied by the well is 120.7 gpm. Average day indoor demand will be closer to 60 gpm.

Conducting the 14-day aquifer test at a constant rate of 150 gpm allowed for careful quantitative analysis of the data. By keeping the pumping rate constant, we were able to observe the delayed-yield response of the aquifer and revise our estimate of the transmissivity downward from our previous estimate of about 500 ft2/day to about 120 ft2/day. The UGS also observed the delayed yield response and estimated a similarly low transmissivity of about 230 ft2/day.

Powder Mountain Aquifer Test and Monitoring Report – E8352 (35-12848)

Our evaluation of the Powder Mountain aquifer test monitoring data indicate no discernible impact due to pumping the Hidden Lake Well at Lefty Spring, Lefty Stream, Pizzel Spring #3, Wellsville Middle Fork, Wellsville Creek near the north boundary of Powder Mountain, Geertsen Creek, or other locations monitored for this study. This is not surprising because many of the monitored locations are far from the pumping well and are isolated from impacts of pumping by the presence of low permeability formations. Lefty Spring and groundwater seeps and springs on the north side of Powder Mountain discharge from the same formation as the Hidden Lake Well. However, effects of pumping the well tend to be localized with most of the produced water coming from the Weber County side of the surface water divide. Aquifer conditions that tend to confine drawdown near the Hidden Lake Well include an aquifer of low transmissivity, faults, possibly higher vertical than horizontal permeability, and seasonal groundwater recharge.

Our conclusion that the monitoring data show no discernible impact due pumping the Hidden Lake Well is confirmed by the UGS evaluations. The UGS (2014a) stated in their presentation to the DWRi (UGS, 2015a) that their evaluation of the monitoring data did not show a statistically significant influence from pumping. The UGS (2015a) also stated that the conditions for the aquifer test were satisfactory and that they doubted any significantly more relevant information would be obtained by doing another pumping test (Larsen, 2015).

The Powder Mountain aquifer test provides a basis to believe that the water under application E5382 (35-12848) can be developed without impairment existing water rights.

Evan D. Miller Powder Mountain Ski Resort P.O. Box 270 Eden, UT 84310

Dear Mr. Miller:

Subject: Temporary Approval, Extended Aquifer Test, Hidden Lake Well (WS008), System #29028, File #9428

On November 18, 2014, in a phone call, William D. Loughlin, P.G., the hydrogeologist consultant for the Summit Mountain Holding Group LLC (Summit Group), requested permission from the Division of Drinking Water, to use the Hidden Lake Well pump house, the Hidden Lake 415K Gallon Tank (ST004), and the Hidden Lake Distribution System (DS001) for an extended aquifer test by pumping the Hidden Lake Well consecutively for 14 days. This test is being conducted under a work plan from the Division of Water Rights to assess interactions, if any, between the Hidden Lake Well and other springs and streams in the area. Normally, in this type of situation, the pump-to-waste line incorporated in the pump house design would be used to conduct a well test, but the pump-to-waste line discharges near the well. In this test it is necessary to discharge the well water some distance away where it would not interfere with the existing springs and streams. The distribution line going to Phase 1C of the development provides a convenient means to discharge the aquifer test water away from the well and where it will not interfere.

The Division of Drinking Water has not issued any operating permits for the Hidden Lake Well, the Hidden Lake 415K Gallon Tank, or the Distribution System that will supply drinking water to Phase 1 of the Summit at Powder Mountain PRUD. This letter is not an operating permit for any of these facilities.

The Division of Drinking Water has no objections to using the Hidden Lake Well, the Hidden Lake 415K Gallon Tank, and the Distribution System to conduct the extended aquifer test and approves subject to the following:

1. The Division requires the Summit Group to obtain written permission, prior to using these facilities, from the Weber County Engineering Department, the Powder Mountain Water and Sewer Improvement District, and any contractors whose work product has not been accepted by the Weber County or Powder Mountain Water and Sewer Improvement District.

2. There is no connection between the Hidden Lake Well, the Hidden Lake pump house, and the

Hidden Lake 415K Tank, and the existing Powder Mountain Water and Sewer Improvement District infrastructure. If there was any connection installed from Powder Mountain Water and Sewer Improvement District to provide water during construction to the well or tank, it must be disconnected prior to the Extended Aquifer Test.

3. The Powder Mountain Water and Sewer Improvement District, or the Summit Group acting on their behalf, is still required to obtain operating permits from the Division of Drinking Water for the Hidden Lake Well (WS008), the Hidden Lake 415K Gallon Tank (ST004), and Distribution System (DS001), prior to pumping, storing, or distributing drinking water to customers.

The Extended Aquifer Test will provide data to the Division of Water Rights to assist with its decision on the Exchange Application Number 35-12848 (E5382). Approval of this Exchange Application is necessary for one point-of-diversion under the water right to be moved to the Hidden Lake Well. Approval of this Exchange Application is necessary before the Division of Drinking Water can issue an operating permit for the Hidden Lake Well. The letter from Kent L. Jones, P.E., the State Engineer, dated November 5, 2014, with the aquifer test scope of work is attached for reference.

If you have any questions regarding this letter, please contact Bob Hart, of this office, at (801)536- 0054, or Ying-Ying Macauley, the Engineering Section Manager, at (801)536-4188.

Subject: Exchange Application E5382 (35-12848) Aquifer Testing Plan For Summit Mountain Holding Group, LLC

Dear Ross:

Loughlin Water Associates, LLC (Loughlin Water), on behalf of Summit Mountain Holding Group, LLC (Summit Group), submits herewith this aquifer testing plan requested in your letter dated November 5, 2014, to the Summit Group.

Table 1 summarizes the monitoring program for the aquifer test at Powder Mountain. Figure 1 shows the locations of the Hidden Lake Well and monitoring points at Powder Mountain (several additional points monitored by protestants are located several miles to the south and are not shown on Figure 1).

OBJECTIVE OF TEST

The objective of the aquifer pumping test is to determine interactions, if any, between the aquifer and spring and creek flows in Weber and Cache Counties by pumping the Hidden Lake Well.

PUMPING PLAN

The Summit Group will conduct the pumping of the Hidden Lake Well utilizing the permanent water system pump and infrastructure. The pump will be powered from the electrical grid (Rocky Mountain Power system) or a temporary generator if necessary.

The initial pumping rate will be 150 gallons per minute (gpm). The operator will attempt to maintain a relatively constant pumping rate while maintaining a water level in the well that is a minimum of 10 feet above the pump. The pumping rate will be adjusted if conditions in the well are such that the pumping rate can be significantly increased, or if conditions indicate the pumping rate should be decreased to maintain

Loughlin Water Associates LLC the minimum water level above the pump, or otherwise maintain the integrity of the well and pumping system. The pumping rate will be re-evaluated during the progression of the test.

Table 2 lists the planned schedule for system shakedown and aquifer testing.

The plan is to pump the well for 14 consecutive days. Short-term shutdown may occur for safe refueling or maintenance of the generator, if necessary, or other unforeseen problems. The plan is to pump from the well, through the pump house to the 415,000- gallon tank. From the tank, water will flow through the system pipeline to a hydrant. From the hydrant, water will flow through temporary piping to the base of Lefty Canyon, as shown on attached Figure 1.

Summit Group will provide manpower to operate the pump and generator (if utilized). The operator will control the discharge rate using the system valve in the pump house. The pump house will have a digital display that shows the water level in the well and the pumping rate. A datalogger will record the water level and pumping rate during the test. In addition, the operator will periodically record water levels and pumping rate from the digital display and will record totalizer readings. The plan is to provide an operator around the clock for the first day or two, after which the operator will check and adjust the system on a part-time basis as conditions allow.

During the pumping period, we will provide the State Engineer and interested parties with an approximately daily e-mail that includes the following information: pumping rate, gallons pumped since previous day’s report, water level in Hidden Lake Well, problems encountered and actions taken, and changes, if any, planned for the pumping program.

MONITORING PLAN

Table 1 summarizes the monitoring plan. Monitoring of all points is underway. All points will be monitored for at least one week prior to pumping, during pumping, and for one week following cessation of pumping. We will provide monitoring data to the State Engineer on a weekly basis during the testing period.

RESULTS

We will report data generated during the monitoring and pumping periods on a daily or weekly basis as discussed above. Following the test, we will provide a written report to the State Engineer that summarizes data collected, our analysis and assumptions.

HIDDEN LAKE WELL

Hidden Lake Well Pumping

The Summit Mountain Holding Group, LLC (the Summit Group) pumped the Hidden Lake Well from December 2 through December 16, 2014, for the Powder Mountain Aquifer Test. Widdison Turbine Service, Inc. (Widdison) personnel monitored and adjusted the pumping rate. Widdison personnel manually recorded water level in the Hidden Lake Well (displayed as feet above the pump), pumping rate (displayed as gpm and as total gallons), water tank level and pressure in piping displayed in the pump house. Appendix B provides copies of aquifer pumping test data sheets.

In addition, water level (as feet above the pump) in the Hidden Lake Well and pumping rate (as gpm) were recorded every 5 minutes utilizing a data recorder provided by Delco Western.

The pumping rate held very steady with a few adjustments of the system valve in the pump house. Only one (4-minute) pump stoppage occurred. On December 8, 2014, at approximately 8:36 am the pump shut off (apparently a worker tripped an electrical switch). Widdison staff restarted the pump at about 8:40 am. The total volume of water pumped during the 14-day period was 3,033,700 gallons (average of 150.5 gpm or 216,700 gallons per day).

Hidden Lake Well Water Levels

Figure C-1 is a plot of water level in the Hidden Lake Well versus date for the pumping period and for about a month before and after the pumping period. Figure C-1 shows a diagram of the well to help relate pumping water level to the slotted intervals and the pump setting.

For the month prior to starting the aquifer test, the pre-test background water level trend was downward at approximately 0.27 feet per day as shown on Figure C-2.

Figure C-3 is a plot of pumping water level (in feet above the pump) versus elapsed time since pumping started. The water level at the start of the test was 750.6 feet deep, and fell to a depth of 915.3 feet at the end of the pumping period.

Figure C-4 is a plot of drawdown (corrected for the pre-test trend) versus log-time since pumping started. The Summit Group pumped the well at an average rate of

Appendix-C-PumpTestPlots.doc Page C-1 of 4 January 2015 about 150 gpm for 14 days (20,160 minutes). Drawdown at the end of the pumping period was 160.9 feet (corrected for the pre-test water level trend). We calculated a “critical time” of about 70 minutes using the method of Shafer (1978). Pumping water levels prior to about 70 minutes are significantly affected by casing storage and do not accurately reflect aquifer response. After pumping stopped, water levels recovered (rose) to about 79 percent of the drawdown within one hour and to about 90 percent of the drawdown after one day.

The semi-log graph on Figure C-4 does not show a straight-line response with time that is typical for an extensive, homogeneous, and isotropic confined aquifer. Therefore, we did not use a straight-line method, such as Cooper and Jacob (1946) to analyze the data. Figure C-5 presents a graph of residual drawdown versus the ratio of time since pumping started/time since pumping ceased (t/t’). As with the plot on Figure C-4, the plot does not show the straight-line response that is typical for an extensive, confined aquifer.

Plots of log-drawdown versus log of time since pumping started (log-log plots) may be amenable to analysis using type-curve matching techniques under different and varying conditions. However, if actual conditions in the aquifer do not meet the theoretical conditions assumed for the purpose of mathematical equations, other methods are more appropriate for estimating transmissivity and storage coefficient and for performing other quantitative interpretations.

On Figure C-6, we plotted log-drawdown (corrected for pre-test trend) versus log-time since pumping started. The plot shows a response that occurs in unconfined aquifers due to delayed gravity drainage. The “early time” portion of the plot shows a flattening of the drawdown curve and a “late time” portion that shows an inflection and a steeping of the drawdown curve. We have chosen not to estimate a transmissivity value from the log-log plot of the pumping well because early-time data (prior to 70 minutes) are affected by casing storage, and drawdown in the pumping well is affected by well loss. This is a typical difficulty for analysis of pumping well data in all but the most straightforward situations. We have utilized the methodology to evaluate the data from Exploration Well 2, which is not affected by casing storage or well loss as discussed later in this appendix.

Exploration Well 2 Response to Pumping of Hidden Lake Well

For the month prior to starting the aquifer test, the pre-test background water level trend in Exploration Well 2 was downward at approximately 0.24 feet per day as shown on Figure C-7.

Figure C-8 is a plot of depth to water versus log-time since pumping started (with no corrections for the pre-test water level trend). The water level at the start of the test was 749.6 feet deep, and fell to a depth of 803.2 feet at the end of the pumping period.

Figure C-9 is a plot of drawdown (corrected for the pre-test water level trend) versus log-time since pumping started. Drawdown at the end of the pumping period was 50.2 feet (corrected for the pre-test water level trend). After pumping stopped, water levels recovered (rose) to about 38 percent of the drawdown within one hour and to about 67 percent of the drawdown after one day.

As with the pumping well, the semi-log graph on Figure C-9 for Exploration Well 2 does not show a straight-line response with time that is typical for an extensive, homogeneous, isotropic, confined aquifer. Therefore, we did not use a straight-line method, such as Cooper and Jacob (1946) to analyze the data. Figure C-10 presents a graph of residual drawdown versus the ratio of time since pumping started/time since pumping ceased (t/t’). As with the plot on Figure C-9, the plot does not show the straight-line response that is typical for an extensive, homogeneous, isotropic, confined aquifer.

On Figure C-11, we plotted log-drawdown (corrected for pre-test trend) versus log-time since pumping started. The plot shows drawdown that is less than would be predicted by Theis (1935), but which is typical of unconfined aquifers with delayed gravity drainage; see Hantush (1955), Boulton (1963), Lohman (1972) and Neuman (1972). The “early time” portion of the plot shows a flattening of the drawdown curve and a “late time” portion that shows an inflection and a steeping of the drawdown curve. We analyzed the data using the graphical type-curve matching method developed by Boulton (1963) for unconfined aquifers with delayed yield. We have attached a copy of the Boulton delayed-yield type curves with the figures. Assuming a delayed gravity drainage response during the pumping test, the evaluation of early-time data indicates an aquifer transmissivity of about 118 ft2/day and a confined aquifer storage coefficient of 0.001 (dimensionless) at Exploration Well 2. The evaluation of late-time data indicates an aquifer transmissivity of about 118 ft2/day, and an unconfined aquifer storage coefficient of 0.09 (dimensionless) at Exploration Well 2. The aquifer may depart from the assumptions inherent in the analytical methodology and the parameter values should be considered approximations.

Note that the Utah Geological Survey (UGS) in their analysis of the data from the aquifer test (UGS, 2015) also recognized the delayed-yield response of the aquifer. The UGS (2015) used the method of Barlow and Moench (1999 and 2011) for unconfined aquifers with delayed yield to estimate a transmissivity of 228 ft2/day, storage coefficient of 0.006 (dimensionless) and a specific yield of 0.07 (dimensionless).

MEMORANDUM – WATER SAMPLING AND WATER CHEMISTRY EVALUATION

Loughlin Water Associates LLC Memorandum

Date: February 3, 2015

To: Loughlin Water Associates, LLC

From: Neil I. Burk, P.G.

Subject: Water Sampling and Water Chemistry Evaluation Powder Mountain, Utah

This memorandum summarizes data obtained from the collection of water samples in the Powder Mountain area from springs, selected streams, exploration wells and the Hidden Lake Well. Data includes general chemistry from the streams, springs and wells, oxygen-18 and deuterium isotopic data from the streams, springs and Hidden Lake Well, and tritium isotopic data from the Hidden Lake Well and Lefty Spring. Water samples from the exploration wells and the Hidden Lake Well were collected in 2013 and water samples from the springs, selected streams and the Hidden Lake Well were collected in 2014.

PURPOSE AND OBJECTIVES

The purpose and objectives were to collect water sample data to evaluate source and groundwater recharge areas in the Powder Mountain area.

BACKGROUND

During summer 2013, as part of the groundwater exploration program, water samples were collected from Exploration Well #1 and Exploration Well #2 during air lift testing of the boreholes. The water samples were analyzed for general chemistry parameters. During fall 2013, as part of the Utah Division of Drinking Water (DDW) permitting process for the Hidden Lake Well, water samples were also collected from the Hidden Lake Well after pumping the well for 24 hours at rates of 180 gallons per minute (gpm) and 112 gpm, respectively. The water samples were analyzed for the general chemistry parameters required by the DDW for a new groundwater source. Additional information about the drilling, construction and testing of Exploration Well #1, Exploration Well #2 and the Hidden Lake Well can be found in Loughlin Water (2013a, 2013b and 2013c).

On September 4, 2014, Neil Burk, P.G., Project Hydrogeologist with Loughlin Water Associates, LLC (Loughlin Water) collected water samples from eight (8) sites at Powder Mountain, which include springs, selected streams and the Hidden Lake Well. Water samples from the Hidden Lake Well were collected at an isolated depth interval of 1334 to 1347 feet while additional well development was being conducted. The water samples were analyzed for general chemistry parameters and oxygen-18, deuterium and tritium isotopes. An additional water sample for general chemistry was collected

Loughlin Water Associates LLC Memorandum from the Hidden Lake Well on December 10, 2014 after pumping the well for 185 hours (7.7 days) at 150 gpm.

The 2013 and 2014 general chemistry samples were analyzed by Chemtech-Ford Laboratories in Sandy City, Utah. The oxygen-18 and deuterium isotopic samples were analyzed by the Stable Isotope Ratio Facility for Environmental Research (SIRFER) at the University of Utah and the tritium isotope samples were analyzed by the Dissolved and Noble Gas Lab at the University of Utah in Salt Lake City, Utah.

RESULTS

Figure 1 shows the water sample locations and Table 1 lists the types of water samples collected at each site. Tables 2 and 3 summarize laboratory results for the water samples collected in 2013 and 2014, respectively. Attachments A, B and C present copies of the laboratory analytical reports for the general chemistry water samples collected in 2013 for Exploration Well #1 Exploration Well #2 and the Hidden Lake Well, respectively. Attachment D presents copies of the analytical reports for the general chemistry water samples collected in 2014. Attachment E presents a copy of the analytical report for oxygen-18 and deuterium isotopes and Attachment E presents a copy of the analytical report for tritium.

DISCUSSION

GENERAL CHEMISTRY

Tables 2 and 3 show that the water in the Powder Mountain area is slightly alkaline with pH ranging from 7.49 to 8.66 with water from the wells and springs having pH values less than 8 and water from surface water locations greater than 8. For the 2014 samples, total dissolved solids (TDS) concentrations are generally less than 200 milligrams per liter (mg/L), with the exception of Pizzel Spring #3 which is 308 mg/L. The 2013 samples collected from the exploration wells and Hidden Lake Well were generally greater in TDS, which is likely related to elevated turbidity levels. Groundwater temperatures measured in the field range from about 41 to 46 degrees Fahrenheit (°F).

Figure 2 presents a Piper Diagram of the water samples collected at Powder Mountain in 2013 and 2014. As shown on the Piper Diagram, most of the samples group closely together, which indicate that the waters in the Powder Mountain area are chemically similar. The dominant cations of most of the water samples are calcium followed by magnesium. The dominant anion is bicarbonate. As such, the water around Powder Mountain is described as being calcium-bicarbonate type, but with a significant percentage of magnesium.

The water sample from Pizzel Spring #3 is different from the other samples by its sodium and chloride content. We believe that the relatively higher sodium and chloride concentrations in the Pizzel Spring #3 sample may be from road salt applied to the

Doc15-02-SMHG-PowderMtn- Page 2 of 7 Pages February 3, 2015 WaterChemEval

Loughlin Water Associates LLC Memorandum

Powder Mountain road during the winter, as the spring collection box is located next to the road. As shown on Figure 2, Pizzel Spring #3 plots in the no dominant cation region of the Piper Diagram. The most abundant cation is calcium, followed by magnesium then sodium. The water also plots in the bicarbonate region of the Piper Diagram, but with a significant amount of chloride.

The two water samples collected during air lift testing from Exploration Well #1 (see Table 2 and Figure 2) were different from each other. The borehole during each sampling event was open to the Wasatch Formation, the Nounan Formation, the Calls Fort Shale and the Middle Limestone Members of the Bloomington Formation. The sample collected on May 30, 2013 (borehole depth of 2800 feet), the borehole was also open to the Hodges Shale. As shown on Figure 2, the two Exploration Well #1 water samples plot in the no dominant cation region and the bicarbonate region of the Piper Diagram. This may be related to the thickness of Wasatch Formation in the borehole. The most abundant cations in the 2400-foot sample are calcium and magnesium followed by sodium. The most abundant cations in the 2800-foot sample are calcium followed by sodium then magnesium.

Much of the water in the Powder Mountain area flows over or through Paleozoic-age carbonate (limestone and dolomite) bedrock units. Because of the abundance of these carbonate bedrock units in the Powder Mountain area, the surface and groundwater in the vicinity is calcium and bicarbonate type water but with a significant amount of magnesium.

STABLE ISOTOPES

Figure 3 presents a plot of oxygen-18 versus deuterium for the Powder Mountain water samples and the global mean meteoric water line (GMWL) from Rozanski and others (1993). For a background discussion on oxygen-18 and deuterium isotopes, see Clark and Fritz (1997). As shown on Figure 3, the Powder Mountain samples plot above the GMWL, which indicates that the Powder Mountain samples are “depleted” in the heavier isotopes of oxygen and hydrogen. The Powder Mountain samples all plot near each other, which suggest that the waters at Powder Mountain have a similar origin.

Figure 4 presents theoretical oxygen-18 and deuterium precipitation data for each month of the year at the location and elevation of the Hidden Lake Well, and the Powder Mountain water samples. The theoretical oxygen-18 and deuterium precipitation data were obtained from the Online Isotopes in Precipitation Calculator (OIPC) available at Waterisotopes.org. Table 3 summarizes the OIPC data for Powder Mountain. The OIPC allows for the estimation of the modern mean annual and monthly deuterium and oxygen isotope composition of precipitation at a specific location. The estimates were calculated from a global data set according to an algorithm developed by Bowen and Wilkinson (2002) and refined by Bowen and Revenaugh (2003) and Bowen and others (2005).

Loughlin Water Associates LLC Memorandum

As shown on Figure 4, the OIPC estimates plot near the GMWL, as do the Powder Mountain samples. The aquifers at Powder Mountain are recharged by precipitation that falls on the ground and most of the precipitation at Powder Mountain falls as snow during the colder months of the year. Recharge predominantly occurs when the winter snowpack melts, saturates the ground and infiltrates into fractures and other connected pore spaces in the bedrock. Water that does not recharge the groundwater either runs off into streams as surface water or lost to evapotranspiration. Figure 4 also shows the average of October to June OIPC data, which plots near the Powder Mountain samples. This suggests that water at Powder Mountain consists of a mix of precipitation that fell between October and June. In general, by the time recharging groundwater infiltrates into the aquifer, the water is well mixed and is homogeneous (Clark and Fritz, 1997). It is unlikely that much, if any, summer precipitation at Powder Mountain recharges the groundwater.

Because the Powder Mountain samples plot above the GMWL, sublimation and evaporation from the snowpack and infiltrating water is likely not significant. A linear regression of the oxygen-18 and deuterium data for all of the purely groundwater Powder Mountain samples (Hidden Lake Well, Lefty Spring, Lower Lefty Spring (not to be confused with the so called Lower Lefty Weir), East Fork Spring and Pizzel Spring #3) yields a slope of 6.7. Clark and Fritz (1997) indicate that enrichment in the heavier isotopes through evaporation yields a slope that varies between 3 and 5. Additionally, enriched waters plot below the GMWL.

Figure 5 shows a plot of the deuterium data versus chloride concentration. The Powder Mountain samples have chloride concentrations that range between 2 and 3 mg/L, excluding Pizzel Spring #3, which has a chloride concentration of 68 mg/L. Figure 5 indicates that as the deuterium becomes more enriched (less negative) in the heavier isotopes, the chloride concentration is relatively constant. If evaporation is significant during the recharge process then an increase in chloride concentration would be expected as deuterium becomes more enriched (positive slope of regression line).

Groundwater recharge at Powder Mountain is likely a relatively rapid process, as suggested by the lack of an evaporative signature in the Powder Mountain samples. However, most recharge occurs from infiltration of snowmelt, which consists of a mixture of water that fell during each storm. Enrichment of the snowpack in heavier isotopes likely occurs, but is probably not significant.

TRITIUM

We collected samples for analysis of tritium to obtain a qualitative age date for groundwater from Lefty Spring and the Hidden Lake Well. For a background discussion on dating groundwater using tritium, see Clark and Fritz (1997). Groundwater from Lefty Spring had a tritium concentration of 6.58 tritium units (TU) and the Hidden Lake Well had a tritium concentration of 8.13 TU. Clark and Fritz

Doc15-02-SMHG-PowderMtn- Page 4 of 7 Pages February 3, 2015 WaterChemEval

Loughlin Water Associates LLC Memorandum

(1997) indicate that groundwater with tritium concentrations of 5 to 15 TU are modern with recharge ages of less than 5 to 10 years.

It is likely that older groundwater exists in the aquifers at Powder Mountain and that mixing of groundwater with different ages occurs during recharge and within the aquifer. Given that Powder Mountain is in a recharge area, at the top of the drainage basin, the bulk of the groundwater in the Powder Mountain area is likely modern as supported by the tritium analysis. Older groundwater is likely located at greater depths or in isolated parts of the aquifers and may discharge from springs at lower elevations that are connected with the deeper or isolated parts of the aquifers.

SUMMARY AND CONCLUSIONS

During summer 2013, as part of the groundwater exploration program at Powder Mountain, water samples were collected from Exploration Well #1 and Exploration Well #2. During fall 2013, as part of the DDW permitting process for the Hidden Lake Well, water samples were also collected from the Hidden Lake Well at the end of 24- hour constant rate pumping tests. All of the water samples collected in 2013 were analyzed for general chemistry parameters.

On September 4, 2014, Loughlin Water collected water samples from eight (8) sites at Powder Mountain, which include springs, selected streams and the Hidden Lake Well. Water samples were collected for analysis of general chemistry and oxygen-18, deuterium and tritium isotopes. An additional water sample for general chemistry was collected from the Hidden Lake Well on December 10, 2014.

Water in the Powder Mountain area is predominantly calcium-bicarbonate type, but with a significant amount of magnesium. Water samples collected from Exploration Well #1 in 2013 had significant concentrations of calcium, magnesium and sodium, but without a dominant cation, while bicarbonate was the dominant anion. Pizzel Spring #3 also lacked a dominant cation and had significant concentrations of calcium, magnesium and sodium, and was dominant in bicarbonate with a significant amount of chloride.

Water in the Powder Mountain area is slightly depleted in heavier isotopes of oxygen and hydrogen, but plots near the GMWL. Groundwater in the area is likely a mix of late fall, winter and spring precipitation, which generally falls as snow. Evaporation and sublimation from the snowpack likely occurs, but is not significant. Recharge of the groundwater likely occurs relatively rapidly during late spring as the snowpack melts.

Groundwater from Lefty Spring and the Hidden Lake Well is modern (i.e. less than 10 years old) as suggested by the tritium concentrations in water samples collected from the two sources. Older groundwater likely exists in the Powder Mountain area, but is likely found at greater depths and in isolated parts of the aquifers.

Flag Descriptions SPH = Sample submitted past method specified holding time.

SL-01 = Analysis performed by American West Analytical Labs, 463 W. 3600 S., Salt Lake City, UT 84115.

QM-4X = The spike recovery was outside of QC acceptance limits for the MS and/or MSD due to analyte concentration at 4 times or greater the spike concentration. The QC batch was accepted based on LCS and/or LCSD recoveries within the acceptance limits.

QM-010 = The MS recovery was outside acceptance limits but passed Duplicate Spike acceptance Limits. The batch was accepted based on the acceptability of the MSD as the batch Spike.

A-01 = There is good correlation on the action/anion balance on this sample. However, the significant amount of solids present in the sample has caused the theoretical/actual TDS (which was re-run for verification) correlation to be higher than expected.
