of Green Canyon Well No. 5 (Well) for North Logan City (City). Green Canyon Well No. 5 is a new water supply well for North Logan City that was drilled and constructed to Utah public drinking water supply standards. The Green Canyon Well No. 5 is located at approximately 1899 East Green Canyon Drive in North Logan, Utah, approximately 1,020 feet north, 508 feet west of the east quarter corner of Section 24, Township 12 North, Range 1 East, SLB&M as shown in Figure 1 and Figure 2. The well drilling began in January 2023 and the development and testing were completed in May 2023. Design plans and specifications for Green Canyon Well No. 5 were completed by Bowen Collins & Associates (BC&A) in March 2022. The plans and specifications were incorporated into bid documents prepared by BC&A. In April 2022, the City solicited bids from qualified well drilling contractors. Hydro Resources (Hydro) was awarded the work and entered into a contract with the City in September 2022 for construction of Green Canyon Well No. 5. PERMITTING Utah Division of Drinking Water Approvals In April 2022 a Preliminary Evaluation Report (PER) for the Well was prepared by BC&A and submitted to the Utah Division of Drinking Water (DDW). The PER was subsequently approved and granted by DDW in a letter dated September 26, 2022. A copy of the DDW approval letter is provided in Appendix A. In March 2022 BC&A completed well construction plans and specifications for the Well. The plans and specifications documents were submitted to the DDW Engineering Section for review and approval. Specification and plan approval for the Green Canyon Well No. 5 was granted by DDW in a letter dated September 26, 2022. A copy of the DDW approval letter is provided in Appendix A. Utah Division of Water Rights Approvals The City obtained a provisional well drilling start card from the Utah Division of Water Rights (UDWRi) and provided it directly to Hydro (Utah licensed Well Driller No. 815). The well drilling start card was issued under Non-Production Well Application 2225001M00. A copy of the State Engineer’s approval letter dated September 8, 2022 for the provisional well application along with the driller start card is included in Appendix B. PRODUCTION WELL DRILLING AND CONSTRUCTION Borehole Drilling The well location was originally staked by City personnel and Chris DeKorver of BC&A in April 2022. At the onsite pre-construction meeting with Hydro and the City in September 2022 the well location was moved approximately 20 feet southeast of the staked location due to site constraints on the drill rig setup. Well drilling activities for the Green Canyon Well No. 5 began on January 20, 2023. A 36-inch diameter borehole was drilled with a bucket auger drill rig to a depth of approximately 111 feet below ground surface (bgs) by Pete Martin Drilling. The driller reported that the alluvial material at the base of the borehole felt moderately consolidated, though was deeper than expected based on GREEN CANYON WELL NO. 5 REPORT BOWEN COLLINS & ASSOCIATES NORTH LOGAN CITY 2 adjacent well logs. A 28-inch diameter, 0.375-inch wall, mild steel ASTM A-53, Grade B surface casing was installed in the borehole with a sand cement grout. The surface casing was sealed in place using an average 19.0 lb/gal sand cement mix (Type II-V Portland Cement, ASTM C150). A total of 24 cubic yards of grout were used on the surface casing seal. Chris Mikell, P.G. of BC&A, a DDW authorized grout seal certifier, witnessed the grouting of the surface casing to verify proper seal placement. The grout certification report for the Well is included in Appendix C. Following installation of the surface casings, a 14 ¾-inch diameter pilot borehole was drilled with the Schramm T-130 drill rig utilizing the reverse circulation air rotary drilling method utilizing only fresh water and a tri-cone button faced bit. Chlorinated potable water obtained from a nearby North Logan fire hydrant was used to create any drilling fluids that were used. During borehole drilling, drilling fluids were pumped to a sample catcher box where cuttings samples were obtained every 5 feet for geologic logging. The drilling fluid was circulated into a shaker table mud system tank for cuttings removal before recirculation back into the borehole. During drilling the pilot hole, Hydro reported issues with borehole caving. On February 8, 2023 Hydro installed a 3 yard sand-cement slurry form 126 to 98 feet. Drilling continued February 9, 2023 and Hydro utilized bentonite drilling mud and polymer additives to keep the hole open. Competent bedrock was reached at a depth of 155 feet. Hydro elected to backfill the borehole with sand cement to avoid caving. Sand cement was placed from 155 to 110 feet on February 13, 2023. Drilling continued on February 14, 2023 at a rate of 6ft/hour. On February 17, 2023 at a depth of approximately 598 feet the borehole began to collapse near the base of the surface casing around 110 feet. A bridge occurred in the borehole between 110-115 feet. Hydro attempted to cement off the area below the surface casing by installing 2 yards of cement grout. The grout plug did not hold, and drilling was stopped. On February 27, 2023 a decision was made to utilize a dual-rotary drill rig to install a 24-inch casing into bedrock. This change to the well design was approved by the City. The 24-inch casing was installed to a depth of approximately 156 feet on March 14, 2023 by Cascade Drilling. Continuation of the pilot borehole drilled began on March 15, 2023 using an 14 ¾-inch diameter tri-cone button faced bit and a tricone button bit. The total depth of 809 feet was reached on March 17, 2023. Geophysical logging of the 14 ¾-inch pilot borehole was conducted on March 18, 2023 upon removal of the drill stem and bit from the borehole. The geophysical log suite consisted of spontaneous potential, single point resistance, 16-inch and 64-inch resistivity, neutron, and natural gamma. Information from the pilot borehole was processed on a fast turnaround and used to design the well. Drill cutting samples were not submitted for sieve analysis because the borehole below 150 feet is bedrock formation and sieve information would have provided no useful information. BC&A evaluated the geologic and geophysical logs and provided final well design recommendations to the City. After City approval of recommended well design, BC&A provided the final well design requirements to Hydro for construction of the Well. Copies of the geophysical logs are contained in Appendix D. Figure 3 provides a geologic log for the Green Canyon Well No. 5 based on the drill cutting samples and geophysical logs obtained from the well boring. Based on the geologic log and geophysical log, BC&A recommended #4 x 3/8” gradation gravel pack with 0.100-inch slot well screen was appropriate for the well design. BC&A recommended the placement of the screens based on interpretation of the geophysical logs and drillers notes on fracture zones in the bedrock formation. GREEN CANYON WELL NO. 5 REPORT BOWEN COLLINS & ASSOCIATES NORTH LOGAN CITY 3 The water bearing zones identified and recommended for well screens were between 370 to 710 feet. A total of 240 feet of well screens were recommended. Appendix E contains a copy of the Well Driller’s Report as submitted to the UDWRi by Hydro. The 14 ¾-inch pilot borehole was reamed out by Hydro to a 22.5-inch diameter production borehole using a 22.5-inch diameter button-faced tricone reamer bit from March 30 through April 2, 2023. The production well borehole was drilled to a depth of 720 feet bgs. The total drilled depth includes a 5-foot rathole deemed necessary by Hydro to allow installation of the well casing to a depth of 715 feet bgs. Screens were placed at the depth intervals specified by BC&A and a total of 240 feet of screen was used in the well. The well screen is 304 stainless steel wire-wrap provided by Roscoe Moss Company. Well Construction An as-built well completion drawing for the Green Canyon Well No. 5 is provided in Figure 4. Well construction took place from April 2 through April 7, 2023. Mild steel, 0.375-inch wall, 16-inch diameter casing was installed in the borehole to a depth of 370 feet bgs, 400 to 420 feet, 530 to 570 feet, and from 630 to 650 feet bgs. From 370 to 400 feet bgs, 420 to 530 feet, 570 to 590 feet, 610 to 630 feet, and 650 to 710 feet bgs the well was constructed out of 304 stainless steel 16-inch diameter wire-wrap well screen. A total of 240 feet of 0.100-inch slot screen was used in constructing the Well. A 5-foot section of 0.375-inch wall mild steel casing was installed at the bottom of the well from 710 to 715 feet bgs to serve as a sump. Specifications for the well screen are located in Appendix F. Following installation of the screen and casing, disinfected (chlorinated) gravel pack was pumped progressively into the annular space between the well casing and the borehole wall from the bottom of the borehole to 160 feet bgs using tremie pipe. Gravel pack for the 0.100-inch slot screen consisted of 3/16” x 3/8” gradation gravel manufactured by Industrial Silica. A total of 32 super sacks (995 ft3) were installed between 175 to 720 feet. Specifications for the gravel pack material are located in Appendix F. A total of 18 yards of neat cement grout were installed in the annular space from 175 feet to ground surface between the 24-inch and 16-inch casing and the 24-inch and 28-inch casing. Appendix G contains copies of the Well Driller’s Daily logs during the drilling and construction of the well. WELL DEVELOPMENT Initial Development Initial well development was started on April 5, 2023 and continued through April 7, 2023. The fluid level in the well was measured at approximately 110 feet bgs prior to initiating development. The initial well development consisted of raising and lowering a mechanical swabbing tool in the screened sections of the well while airlift pumping the Well. The swabbing tool was fabricated from a 10-foot-long section of perforated pipe with rubber swabs at each end. The swabbing tool was attached to the end of the drill pipe. Airlift pumping was conducted while swabbing the well screen intervals. The airlift discharge rate was estimated at 250 to 420 gallons per minute (gpm). Discharge water from the initial development was captured in a Baker tank. The development water was allowed to settle out and clear in the tank before discharge to the ditch south of the drill site. The screened intervals of the Well were swabbed and airlifted with the drill rig for 43 hours. During development of each screen section, the discharge water became visibly clear, and no gravel GREEN CANYON WELL NO. 5 REPORT BOWEN COLLINS & ASSOCIATES NORTH LOGAN CITY 4 pack material or significant sand was observed in the discharge water. Initial development was completed on April 7, 2023, and Hydro commenced preparing to install the annular grout seal. Pumping Development Pump development and testing was conducted by Hydro. On May 20, 2023 a vertical turbine test pump was installed to a depth of approximately 353 feet. The test pump was a Simflow SM14HH, 5- stage, installed on 10-inch column with a 2 ½-inch tube and 1 11/16-inch shaft. The test engine was a 1,200 HP Detroit diesel. Discharge was measured using an in-line totalizing flow magmeter and an 8-inch orifice plate with manometer. A Rossum sand tester was also installed to measure sand content during pumping. The discharge pipe was 10-inch diameter and conveyed water to the adjacent ditch. Two (2) 1-inch diameter PVC sounding tubes were installed adjacent to the pump column pipe for the purpose of water level measurement. One sounding tube was used for manual water level readings. The other sounding tube was used to install an electronic pressure transducer for measurement of the water level during pumping. Pump development was initiated on May 22, 2023 and was completed on May 28, 2023. The static water level in the well was measured at 111 feet bgs at the start of development. The well was pumped and surged for a total of about 60 hours with discharge rates ranging from 700 to 2,160 gpm. The well was intermittently surged by turning the pump off and allowing the water in the pump column to cascade back into the well screen. The well was surged two to three times every 60 minutes during the pump development period. In general, the well produced 4 to 40 ppm sand for 10 to 20 minutes after surging, after which the sand content dropped to less than 5 ppm. Development pumping data is to be contained in Appendix H. At the end of pump development, the well water was clear and non-turbid, and sand production was reduced to less than 3 ppm. It should be noted that the Green Canyon Well No. 4 was operating at the time of development and showed some minor impacts in the development data. The pumping level was impacted as much as 5 feet by Well No. 4. PRODUCTION WELL TESTING Step Rate Test A step rate drawdown test was conducted on Green Canyon Well No. 5 on May 29, 2023. The well was pumped at five successively higher pumping rates while drawdown at each rate, or step, was recorded. Prior to starting the step rate test, the static water level was measured at 118.96 feet bgs. Based on the initial static water level of 111 feet bgs on May 22nd the well had not fully recovered before the start of the step test. Test plans called for the well to be pumped at rates of 1,096, 1,308, 1,520, 1,733, and 1,945 gpm. Actual pumping rates based on totalizer flow readings varied slightly from the planned rates due to the ability to control the motor speed. The actual flow for the step test were recorded at 1,034, 1,317, 1,533, 1,746, and 1,943 gpm. Pumping at each step was maintained for 2 hours. Water level was monitored using a manual water level meter and also recorded using an In-Situ Hermit, which is an electronic pressure transducer and datalogger that was placed in the well. Step rate test pumping data are contained in Appendix I. The transducer used during step rate testing had a pressure range of 300 psi (693 feet of water). The transducer was installed at 350 feet bgs and was about 240 feet below the static water. Manual water level measurements were also used for evaluating the initial step test results. GREEN CANYON WELL NO. 5 REPORT BOWEN COLLINS & ASSOCIATES NORTH LOGAN CITY 5 Drawdown in the well during each step is shown in Figure 5. The specific capacity of the well was determined based on the average pump rate during the step and the drawdown at the end of each step. Table 1 displays the pumping rates, depth to water and associated drawdown for each step. Table 1 Summary of Step Test Data for the Green Canyon Well No. 5 Discharge (Q) (gpm) Pumping Water Level (ft) Drawdown (ft) Specific Capacity (gpm/ft) 1,034 171.2 52.2 19.8 1,317 193.3 74.3 17.7 1,533 220.3 101.4 15.1 1,746 257.0 138.0 12.6 1,943 291.3 172.4 11.3 Specific capacity estimates ranged from 11.3 gpm/ft at 1,943 gpm to 19.8 gpm/ft at 1,034 gpm. Green Canyon Well No. 5 is a high yield and moderately efficient well. The step test results indicate the specific capacity decreased with increased pumping rate. The specific capacity of the well is generally inversely proportional to the discharge rate (i.e. the higher the pumping rate, the lower the specific capacity). There is an apparent change and/or sudden decrease in the specific capacity of the Green Canyon Well No. 5 between 1,533 gpm and 1,746 gpm. The well appears to display increased drawdown for the last two steps. This suggests that the well is more efficient at 1,533 gpm versus 1,746 gpm. Constant Rate Test Following evaluation of the step rate pump test data, a pump rate of 1,950 gpm was selected for the 24-hour constant rate test. This was the maximum pump rate based on what the well can provide and not based on the test pump provided by Hydro for the project. The well was allowed to recover for 17 hours before beginning the constant rate test. The well was pumped at an average rate of 1,985 gpm for 24 hours beginning on May 30th and ending on May 31, 2023. The static water level at the beginning of the test was at 119.0 feet bgs. This static water level is slightly lower than the static water level at the start of step test and indicates the well did not fully recover and that some residual dewatering of the aquifer occurred after only 3 days of pumping. The water level in the Well was monitored using a manual water level meter and also recorded using the In-Situ Hermit. Constant rate test pumping data are contained in Appendix J. There are minor differences between the manual measurements and the transducer measurements. Manual water level measurements were used to define the initial depth to water value for the transducer. Transducer information has been used to create report figures and drawdown curves. SCADA data provided by North Logan City showed there was approximately 18 feet of drawdown in the adjacent Green Canyon Well No. 4 from the 24-hour pump test conducted on the new Well. Figure 6 depicts a semi-log plot of drawdown versus time in the Green Canyon Well No. 5 during the constant rate pump test. Water levels in the well dropped rapidly during the first minutes of pumping. After the initial drawdown, the water level continued to decline for the remainder of the test. The pump rate was relatively constant at 1,985 gpm over the 24 hours of the test. There do not appear to be significant drawdown level changes or trends in the 24-hour test data that would indicate a nearby boundary condition is present, such as an impermeable boundary. The pump in GREEN CANYON WELL NO. 5 REPORT BOWEN COLLINS & ASSOCIATES NORTH LOGAN CITY 6 the well was shut off after 24 hours of pumping. Recovery data was collected for approximately 6 hours, however, there was no check valve installed above the pump and therefore the recovery data is of limited use for estimating aquifer properties. The pumping water level in the Green Canyon Well No. 5 at the end of the constant rate test was about 323 feet bgs, or about 204 feet of drawdown. Using the pump rate of 1,985 gpm results in a specific capacity estimate of 9.7 gpm/ft after 24 hours of pumping. The transmissivity calculated from this specific capacity using the empirical method described by Driscoll (1986) and assuming unconfined aquifer conditions is 1,945.2 feet squared per day (ft2/day). Pump test data were used to estimate aquifer properties such as transmissivity of the water bearing zones tapped by the well. The total thickness of the aquifer zones contributing to the Well were estimated from the geologic and geophysical logs at 240 feet. In reality it is believed the highly fractured zones contributing most of the flow to the Well are much less than 240 feet. Utilizing Aquifer Test v 10.0 (Waterloo Hydrogeologic, Inc, 2020) software, methods by Cooper and Jacob (1946) and Theis (1935) were used to evaluate the transmissivity assuming confined aquifer conditions. Plots showing transmissivity evaluations are located in Appendix K. Table 2 summarizes aquifer transmissivity estimates obtained using the Green Canyon Well No. 5 pump and recovery test data. Transmissivity estimates ranged from approximately 1,945 to 2,970 ft2/day, with an average of 2,621 ft2/day. Table 2 Transmissivity Estimates for Green Canyon Well No. 5 Pump Test Analysis Method Transmissivity (ft2/day) Theis (1935) Log-log Curve Match Method 2,970 Cooper-Jacob (1946) Straight line Method 2,950 Driscoll (1986) 1,945 Average 2,621 These transmissivity values obtained for the Well are in the moderate range compared to other wells located in the North Logan area. The estimated aquifer storativity from the pump test using the Theis curve match method is 5.23E-5 (dimensionless). The estimated aquifer storativity is representative of a confined aquifer (specific yield range 10-3 to 10-6). There are no significant confining layers (clays) apparent from the geologic and geophysical logs for the Well and the aquifer is described as unconfined in the area. However, the fractured zones with the bedrock formation underlying the site may act as a confined aquifer depending on the extent of the fractures and whether they connect vertically to the water table aquifer in the alluvial fill at the site (which does not appear to be the case). The Well yield meets the original design expectations for the well site. The Theis equation was used to estimate long term pumping levels in the well after 1 week up through 1 year of continuous pumping at rates between 1,000 gpm and 1,985 gpm. During the step test, it was observed that the well displays increased drawdown at an increased rate. Because of that trend, the aquifer parameters are not consistent between rates. The step test water levels and associated pumping rates were used to define aquifer parameters for long-term operation. Transmissivity estimates and GREEN CANYON WELL NO. 5 REPORT BOWEN COLLINS & ASSOCIATES NORTH LOGAN CITY 7 storativity values were used for four different pumping rates operating from 1 week up through 1 year as shown in Table 3 below. Table 3 Transmissivity and Storativity for Long-Term Projections for Green Canyon Well No. 5 Flow Rate (gpm) Transmissivity (ft2/day) Storativity 1,000 6,500 1.0 E-6 1,300 5,000 1.0 E-6 1,600 5,000 1.0 E-6 1,985 2,500 1.0 E-3 The analyses indicate that adjacent North Logan City wells will be impacted (drawndown) by pumping the new well at each rate (not including each individual well simultaneously pumping at their respective rate). Table 4 summarizes the predicted drawdown values in Green Canyon Well No. 5 between 1 week and 1 year at a continuous rate. While it is unlikely North Logan City would pump the new Well continuously for 1 year, the results indicate the new Well has a high potential to impact (drawdown) other nearby wells and lower the water table in the area. The table also includes a modified pumping water level based on impacts observed from Green Canyon Well No. 4. Table 4 indicates that Green Canyon Well No. 5 is not capable of pumping sustainably at 1,985 gpm for longer than 1 week. The other rates modeled appear to be much more sustainable leaving additional available drawdown above the uppermost screen at 370 feet.

Sand Production Sand content was monitored regularly during development of the well, and during the step and constant rate pump tests. The data indicates that well development efforts were successful in reducing sand content produced. A total of 0.9 mL or 0.33 ppm of sand was produced by the end of the constant rate test. Less than 5 ppm sand was observed after 11 minutes pumping at 1,985 gpm. GREEN CANYON WELL NO. 5 REPORT BOWEN COLLINS & ASSOCIATES NORTH LOGAN CITY 9 Less than 1 ppm was reported after 3 hours of pumping at 1,985 gpm. There are no identified sanding problems or concerns with the well. Water Quality Water quality samples were collected from the Well during the constant rate pump test at 10:50 AM on May 31, 2023. The samples were collected by BC&A staff at a wellhead sampling port and submitted to CHEMTECH-FORD Analytical Laboratory in Salt Lake City, Utah. Samples were analyzed in accordance with the Safe Drinking Water Act and Utah Drinking Water Standards (see most recent version of R309-103 of the Utah Administrative Code) for inorganic parameters, volatiles, pesticides/PCBs, herbicides, carbamates, and semi-volatiles, dioxins, and radionuclides. Appendix L contains the laboratory analytical reports. A piper diagram showing the plotted water quality is included in Appendix L. The Well water is a calcium bicarbonate type water. The lab test results indicate the Well produces very good quality water. The total dissolved solids (TDS) concentration of 260 mg/L is below the EPA Maximum Contaminant Level (MCL) of 1,000 mg/L, and below the Utah Secondary drinking water standard of 500 mg/L. Other inorganic parameters analyzed, such as turbidity, chloride, color, sulfate, nitrate, arsenic, and other metals had concentrations below drinking water standards. No volatiles, semi- volatiles, pesticide/PCBs, herbicides, carbamates, or dioxins were detected in the samples taken from the well. Based on the laboratory water quality test results the Well meets all public drinking water standards and is suitable for use as a public water supply well. Bacteriological testing was not conducted on the well sample taken at the end of the pump test. At that time the Well had not been disinfected. Subsequently the Well was thoroughly disinfected in accordance with AWWA standards prior to the driller demobilizing from the site. Bacteriological testing needs to be conducted when the well is permanently equipped to obtain an operating permit from DDW as a public supply well. FINAL WELL TESTING AND CONSTRUCTION Video Camera Survey A video camera survey was performed on the well on June 12, 2023 to verify the as-built construction and integrity of the constructed well by Century Wireline Services. A DGRT 2848, full color, dual lens, 360-degree view underwater video system was used to conduct the survey. The onscreen depth counter of the video equipment measured one-tenth of a foot increments. The static water level was measured at 109.2 feet bgs at the time of the video. The video indicates the well screens are about 0.5 feet shallower than the well construction as-built provided by Hydro. This may be due to starting point of the camera run or an inaccurate counter on the camera. The Well appeared in good condition at the time the video was conducted, with no damaged or broken casing or screen. There appeared to be less than 2-feet of sediment in the sump at the very bottom of the well. A DVD with the Well video inspection is included in Appendix M. Plumbness and Alignment Testing Plumbness and alignment testing was conducted on the Green Canyon Well No. 5 by gyroscopic methods by Century Wireline Services on May 15, 2023 and June 12, 2023. Appendix D contains the gyro deviation logs. Two gyro logs were performed due to the first log showing the well is beyond the allowable drift for plumbness to the top screen at 370 feet. The allowable drift for a 16-inch diameter well is 3.13 feet to a depth of 370 feet. The gyro on May 15th showed the drift at 5.0 feet, or 1.87 feet beyond the allowable distance. The gyro on June 12th showed a drift of 4.8 feet, or 1.67 feet beyond the allowable distance. Based on standards outlined in AWWA A100-06, the well is not GREEN CANYON WELL NO. 5 REPORT BOWEN COLLINS & ASSOCIATES NORTH LOGAN CITY 10 within acceptable limits with respect to plumbness and alignment to a depth of 370 feet (top screen), or below. The recommended pump setting is either 370 feet or in the blank section between 400-420 feet, both of which are beyond the AWWA specification for plumbness. In addition to the gyro log, the well was checked for dog-legs by lowering a 40 foot dummy pipe, with rigid spindles with a diameter of 14 ¼-inches that helps maintain the alignment of the axes of the rings. The dummy was run into the well on May 11, 2023 prior to the installation of the test pump. The dummy was able to pass freely to the top screen at 370 feet and to the total depth of 715 feet. Well Clean-Out The Well was cleaned out using a sand pump bailer on June 4, 2023 over a 2 hour period. The video log confirmed that there was less than two feet of sediment present in the sump and the clean out was complete. Disinfection The Well was disinfected on June 4, 2023 by injecting a total of 10 gallons of 12 percent sodium hypochlorite solution into the well via a tremie pipe. This volume and strength of sodium hypochlorite solution applied to the well exceeded the 100 ppm concentration of available chlorine throughout the casing and gravel pack volume of the well as specified in AWWA C654-13. A bailer was used to mix the chlorine in the well for 2 hours. On June 5, 2023 approximately 6,500 gallons of potable water was injected into the top of the well to push the disinfectant solution into the gravel pack. Although the well has been thoroughly disinfected in accordance with State of Utah Drinking Water Regulations we recommend it be thoroughly disinfected again when a permanent pump is installed and prior to bacteriological testing needed to obtain an operating permit from DDW. Well Head Completion The well casing extends 1.5 feet above ground surface and was capped with a welded steel cover on top of the well. The surface conductor casings end at ground surface and the annulus is filled to ground surface with neat cement grout. A vent pipe and any necessary modifications to the well casing will be constructed by the pump station contractor at a later date. Photographic Log Photographs of the well construction were taken periodically during the course of the project. A photo log was developed and is included in Appendix N. RECOMMENDATIONS Table 5 summarizes details the Green Canyon Well No. 5 construction details and aquifer properties determined from pump testing the well. The following recommendations are made regarding the Well: Green Canyon Well No.5 is a moderate yield, moderate efficiency well that meets the original design expectations. The Well produces water from fractured limestone and dolomite bedrock formations. The static water in the Well was 109.2 feet bgs in June 2023. The Well was test pumped at 1,985 gpm with a resulting drawdown of 204 feet after 24 hours. The test pumping rate was limited by the well/aquifer, and by not the pump. GREEN CANYON WELL NO. 5 REPORT BOWEN COLLINS & ASSOCIATES NORTH LOGAN CITY 11 The Well was drilled under a UDWRi provisional start card approval. The City should evaluate the water rights it intends to assign to the new Well and obtain UDWRi approval prior to equipping the Well. Water quality of the Well meets all federal and Utah Drinking Water Quality standards. The Well water is a calcium bicarbonate type water. The TDS concentration is 260 mg/L. No analytical parameters exceeded drinking water quality standards. Water quality test results indicate the well is suitable for use as a public drinking water source. Pumping the Well at 1,600 gpm continuously for 1 year will result in an estimated pumping level of about 270 feet bgs with impacts from adjacent wells. At the 1,600 gpm pump rate, drawdown impacts at North Logan City’s nearby wells are predicted to be 30-40 feet. Pumping the well at 1,300 gpm continuously for 1 year will result in an estimated pumping level of about 242 feet bgs. At the 1,300 gpm pump rate, drawdown impacts at North Logan City’s nearby wells are predicted to be 10-20 feet. A minimum pump depth setting of 370 feet bgs is recommended for equipping the well for up to 1,600 gpm. It is also possible to set the pump at about 410 feet bgs and be in a 20-foot pump chamber to allow for maximum drawdown to the top screen. We recommend North Logan City monitor the seasonal static and pumping water levels in all its Green Canyon wells to evaluate long-term effects of pumping the new Well on the aquifer in the area. Green Canyon Well No. 5 is a new high yielding well that has the potential to overdraw the aquifer and lower regional water levels in the area. Surveyed measure point elevations and static water levels in all the City’s wells should be plotted to determine the water level surface in the area. At this time it is believed the static water level in Green Canyon Well No. 5 is very similar to Green Canyon Well No. 4, but lower than other wells in the area. The Well should be thoroughly disinfected in accordance with State of Utah Drinking Water Regulations when a permanent pump is installed and prior to incorporation of the well into the City water system. Analysis of coliform bacteria levels needs to be conducted when the permanent pump is installed to obtain an operating permit. North Logan City needs to refine the Preliminary Evaluation Report (PER) and provide a complete Drinking Water Source Protection Plan for the Well to DDW as stipulated in the approval letter.

Shelley Executive Director DIVISION OF DRINKING WATER Tim Davis Director September 26, 2022 Zachary Root North Logan City 2076 North 1200 East North Logan, Utah 84341 Subject: Plan Approval, Well Drilling, Green Canyon Well 5 (WS010) and Exception to R309-600- 13(2)(b)(ii); North Logan City, System #03015, File #12963 Dear Zachary Root: The Division of Drinking Water (the Division) received the plans and specifications for the proposed Green Canyon Well 5 Drilling from your consultant, Chris DeKorver, P.G. of Bowen and Collins on April 1, 2022. The well drilling start card was sent in by Lance Anderson of Cache Landmark Engineering on September 13, 2022. We understand that this project consists of drilling, completion, and testing of a new drinking water well (Green Canyon Well 5). The Green Canyon Well 5 is identified as WS010 in the Division’s database. The installation will occur within North Logan and be in the same general area as the rest of the Green Canyon Wells. This well will feed into the existing North Logan City distribution system. For the well drilling, a 34-inch diameter hole will be drilled for a 28-inch diameter surface conductor casing. The 28-inch surface conductor casing will be extended to 100 feet below ground surface (BGS). A 24-inch diameter hole will be drilled for the 16-inch diameter steel production casing. The production casing will extend to an estimated 800 feet BGS. Both casings will be grouted in place to 100 feet BGS. We have received the following information for the Green Canyon Well 5 (WS010): 1. Plans and specifications for borehole and well drilling. 2. Preliminary Evaluation Report. 3. Valid Start Card from the Division of Water Rights. We have completed our review of the specifications prepared by Chris DeKorver, P.G. of Bowen and Collins dated March 3, 2022, and found they basically comply with the applicable portions of Utah’s Administrative Rules for Public Drinking Water Systems. On this basis, the plans for drilling of Green Canyon Well 5 (WS010) are hereby approved. This approval pertains to well drilling, development, Zachary Root Page 2 of 3 September 26, 2022 aquifer testing, and disinfection of Green Canyon Well 5 only. Please be aware that discharge permits may be required by the Utah Division of Water Quality for discharges generated during well drilling and aquifer drawdown testing. The Utah Division of Water Rights (State Engineer’s Office) regulates the drilling of water wells. Please be aware that, for public drinking water supply wells, in addition to the Division of Drinking Water’s R309-515 rule, the Division of Water Rights’ rule R655-4 also applies and shall be followed. After drilling is completed, you are required to submit additional information outlined in R309-515- 6(5)(b) and (c) for review and obtain approval from the Director for equipping this well and constructing discharge piping and infrastructure necessary for introducing the well water into the distribution system. After obtaining the well-equipping approval, you’ll then be required to obtain an Operating Permit before the Green Canyon Well 5 (WS010) may be put in service. A checklist outlining the well approval process, including the items required for well equipping and an Operating Permit, is enclosed for your information. Please label the well water sample collected for new source chemical analysis with your water system number UTAH03015 and WS010 (for both the facility ID and sample point ID) on all laboratory forms for each individual source. This will ensure proper identification and entry of the new source chemical analysis results in our database. Approvals or permits from the local authority or county may be necessary before beginning construction of this project. As the project proceeds, a notice of any changes in the approved design, as well as any change affecting the quantity or quality of the delivered water, must be submitted to the Division. We may also conduct interim and final inspections of this project. Please notify us when actual construction begins so that these inspections can be scheduled. This approval must be renewed if construction has not begun or if substantial materials have not been ordered within one year of the date of this letter. Concurrence – Preliminary Evaluation Report The Division received the Preliminary Evaluation Report (PER) for the North Logan Green Canyon Well 5 from your consultant, Christopher DeKorver, PG and Bowen Collins & Associates on April 1, and an exception to rule R309-600-13(2)(b)(ii) submitted April 21, 2022. The Division concurs with this report. This PER must be refined, and a complete Drinking Water Source Protection (DWSP) Plan is submitted within one (1) year of the date of this letter. Refer to R309-600-13(6) and R309-600-7(1). You must submit proof that the delineation has been submitted to North Logan City to be covered under the North Logan City Drinking Water Source Protection Ordinance before the well can receive an operating permit. The exception request to Rule R309-600-13(2)(b)(ii) has been received by the Division. The exception to the rule has been submitted because one septic system, a pollution source, has been documented in zone two of an unprotected aquifer. The following items have been submitted to support the exception request:  A Drinking Water Source Protection Ordinance has been adopted by North Logan City in March 2022. Zachary Root Page 3 of 3 September 26, 2022  A Land Use Agreement (LUA) has been obtained with Paul Israelsen stating that they will not allow or locate any uncontrolled pollution sources on their property, Parcel No 05-004-0007.  The Nitrate monitoring for the Green Canyon Well No 1, 2, 3 & 4 show no increase in Nitrate results since monitoring began, as early as 1993 for Well No 1. This will continue to be monitored as yearly Nitrate samples are reported. o The septic system was documented as being present in the original DWSP plan for Green Canyon Well No. 1 & 2 (concurred with in 2000) and therefore, all monitoring of these sources has included the possible contamination by the pollution source. o No additional uncontrolled PCS or pollution sources will be allowed in the area as North Logan City has adopted a Source Protection Ordinance and LUA have been recorded with Cache County. The exception request to Rule R309-600-13(2)(b)(ii) has been granted by the Division.

A 28- inch diameter mild steel casing was installed in the borehole to a depth of 111 feet bgs. The remaining portions of the well had not been drilled or constructed yet. The annulus between the 28-inch surface casing and 36-inch borehole was filled with sand cement grout by Pete Martin Drilling. The description of the sealing procedures on the 28-inch diameter surface casing I witnessed is provided below. Casing Types Installed: Production Well Casing Materials: 28-inch diameter, Mild Steel ASTM A-53, Grade B, 0.375-inch wall, to a depth of 111 feet. Annulus Size (between borehole and casing): Surface Casing to borehole, 4-inches Pitless Adapter: not planned. Well Sealing Description 28-inch Surface Well Casing Description of the Well Sealing Process: On January 20, 2023 I witnessed the installation of the annular seal between the 28-inch surface well casing and the 36-inch borehole from 111 feet to ground surface. The annulus was sealed via a tremie pipe placed down to 100 feet with 24 cubic yards of truck delivered Type II-V Portland Cement sand cement slurry conforming to ASTM C150 Standards and hydrated to an average weight of 19.0 lbs/gal. The sand cement grout was provided by Kilgore Companies (via 3 trucks) and pumped down the tremie pipe. The grout was pumped by Pete Martin Drilling. The volume of grout installed exceeded the theoretical requirement by about 100% indicating washouts and grout penetration into the formation. Grout Material: Sand cement grout, Portland Cement Type II-V Mr. Tim Davis March 31, 2023 Page 3 Grout Volume (in cu. yds.): 24 cubic yards for the certified seal from 111 feet below ground surface up to ground surface. Grout volume was more than the theoretical volume required. Grout Density (in lbs/gal): 18.9 lbs/gal. (Truck #1, 19.0 lbs/gal, 9 cubic yards; Truck #2, 18.9 lbs/gal, 9.0 cubic yards; Truck #3, 19.0 lbs/gal, 6 cubic yards ). Method of Placement: Pumped via tremie pipe Depth from Surface (in feet): 111 feet Did Grout Come to the Surface? Yes Length of tremie pipe: 110 feet Names & Affiliations of Other Observers Chance Beacham/Pete Martin Drilling and other drill crew members, names unknown Issues Observed during Well Sealing None.
