Box 3603 Logan, UT 84323 sales@jexenvironmental.com September 16, 2024 Robert Beers Utah Division of Water Quality 195 N 1950 W SLC, UT 84116 Subject: Tooele Valley Business Park Request for Approval-in-Concept Robert, This report has been prepared for feasibility evaluation regarding a proposed industrial park development near Burmester, Tooele County, UT. Currently, the 242.78-acre property consists of four parcels. The body politic is Tooele Valley Public Infrastructure District; 8371 South State Street, Suite 202, Sandy, Utah 84070. Contact information for the district is Charles W. Akerlow, 801-913-5959 or email: charles@zenithpartners.org. The development plan is for an inland port/business park. The mixed-use development specifics are unknown at this time, however, best guess assumptions at this time are that it will include warehouses, cafeterias, offices, and possible light industrial units. Effluent sewer is proposed, all buildings will have individual septic tanks and all connect to the proposed LUWD system. If any light industrial user exceeds the influent design conditions, pretreatment will be required prior to conveyance to the LUWD system. The owner has authorized us to proceed with the design report and drawings for a request for construction permit which will follow soon after receiving the Approval-in-Concept requested in this document. Potable Water The well water source for this project is being developed. A “Non-Transient Non-Community” (NTNCWS) “Public Water System” (PWS) #23096, File #13543 as defined by Utah Department of Environmental Quality is underway. The proposed source will be as many as three wells. Locations and modeled protection zones are shown on Appendix C. Per the preliminary evaluation report by Ensign Engineering, “Upon satisfactory determination of water quality and quantity at these sites, it is the intent of the owner to complete construction of one or more of these wells conforming to state regulations for design and construction of drinking water wells (R655-4).” Design Assumptions Proposed: The following is a summary of the proposed wastewater treatment system, including component sizing as believed to be feasible for an Approval-in-Concept. Anticipated maximum design flows for full build out are estimated to be 69,623 gallons per day (gpd) but these flows will likely take years to attain. A phased approach is planned, with Phase 1a designed for a maximum flow of 20,000 gpd and Phase 1b for a maximum flow of 35,000 gpd. Breakout of design flow calculations is provided in Appendix A, “Tooele Valley Public Infrastructure District Sewage Generation”. The Approval in Concept requested for a LUWDS system is intended to handle initial flows based on preliminary design assumptions at this time. As the project develops and more information becomes available, it may be necessary to re-evaluate the overall wastewater treatment plan. Specifically, if flow rates approach or exceed 35,000 gpd additional approval for either an expansion (Phase 2) or other wastewater treatment system as allowed under R317-3 would be required. With that understanding, the proposed LUWDS system is intended to handle a design flow rate up to 35,000 gpd. For Design Basis, Average daily flows (30-day average) are assumed to be 80% of the maximum day flow. Influent characteristics into the LUWDS assumed to be BOD5 ≤ 450 mg/L and TSS ≤ 80 mg/L. If any tenant’s septic tank effluent is higher strength than these parameters, pretreatment will be required prior to conveyance to LUWDS. Sizing for Phase 1a & 1b Septic Tank Capacity Individual septic tanks at each building are proposed, these will meet or exceed 1.5Q (where Q is daily flow in gpd) in combined capacity. Cafeteria kitchen flows will be isolated and flow to a grease interceptor prior to entering the septic tanks where interceptor effluent will comingle with wastewater from toilets, sinks, and showers. Phase 1a minimum combined septic tank capacity shall be 35,000 gallons, Phase 1b minimum combined septic tank capacity shall be 52,500 gallons. Anoxic Recycle Tank & Flow Equalization There is no rule requirement for this tank but we recommend 1Q for equalizing flows into the plant and for buffering treatment processes. This applies to all phases. MBBRa Aeration System Because the anticipated wastewater strength will be higher than residential strength waste, an aeration unit is proposed to reduce BOD prior to conveyance to the packed bed media system. A 28’ unit (MBBRa0828) is proposed for Phase 1a. A 42’ unit (MBBRa0842) may be installed during Phase 1a to serve through Phase 1b. Packed Bed Media System Total area required for phase 1a is 20,000 gpd / 30 gpd per square foot = 667 ft2; 750 ft2 proposed. Total area required for phase 1b is 35,000 gpd / 30 gpd/ ft2 = 1,167 ft2; a total of 1,200 ft2 is proposed. Absorption Area Required Phase 1a - 20,000 gpd / 0.8 gpd/ ft2 = 25,000 ft2 x 0.7 reduction for packed bed media = 17,500 ft2 Phase 1b - 35,000 gpd / 0.8 gpd/ ft2 = 43,750 ft2 x 0.7 reduction for packed bed media = 30,625 ft2 Thirteen percolation tests were conducted in the southeast corner of parcel number 05-054-0-0044. These percolation tests were conducted by Mr. Tristen Leberknight, EIT, and under the supervision of Mr. Mike Huber, PE, both of GSH Geotechnical, Inc, on April 18 and 19, 2024. Percolation results for 12 of the 13 tests ranged from 0.46 minutes per inch (mpi) to 34.3 mpi with the remaining test reported as “failing slow”. The report and test pit logs are included in Appendix D. Ten of the thirteen percolation tests yielded rates less than 11 mpi. Approval-in-Concept Request information per requirements listed in R317-5-4. A. General Information. 1. Project site location is: Tooele Valley Business Park properties are located south of the Burmester Interchange on I-80 at milepost 88.5. Parcels involved in the project are as follows: Parcel IDs 05-054-0-0040, 05-054-0-0041, 05-054-0-0042 and 05-054-0-0044 Burmester, UT 84029 The proposed LUWDS will be located in the SE corner of parcel 05-054-0-0044. 2. The property is owned by: Zenith Bolinder, LLC Representative and Primary Contact is: Attn: Matt Smock 8371 South State Street, Suite 202 Sandy, UT 84070 480-434-5123 matt@zenithparners.org 3. No private and public drinking water sources within a 1-mile radius of the proposed system, although the owners are currently developing as many as three new wells. These are approximated and modeled protection zones 1 and 2 are shown in Appendix C. There are 191 Water Rights Points of Diversion, both private and public, within 1 mile of the proposed system. The varying classification of each point of diversion can be found in the Excel file included with this report. 4. The nearest available sewer is in Grantsville which is 5.7 miles to the south and 38’ higher in elevation. The property is outside the Grantsville city boundary. 5. Proposed uses of the facilities are warehouses, light manufacturing, data center, and offices spaces. B. Soil and Site Evaluation. 1. Soil Exploration Pits and Percolation Testing. a. Thirteen soil test pits were excavated to depths ranging 11-13.5 feet, thirteen percolation tests were conducted in the northwest corner of the property. These percolation tests were conducted by GSH Geotechnical, Inc. on April 17-18, 2024. Percolation results for twelve of the tests ranged from 0.46 mpi to 34.3 mpi with one failing slow. Soils consisted primarily of clay with varying silt, sand, and gravel content, full geotechnical report has been provided in Appendix D. The absorption system has been sized using the soil loading rate 0.8 gpd/ft2 Standard trenches are proposed, multiple zones will be used. The absorption area and reserve area are shown on the site plan in Appendix B. g. Based on the soils evaluations and R317-4, Table 6, the proposed soil loading rate used for system sizing is 0.8 gpd/ft2. 2. Wind-Blown Sand. Based on soil pits evaluated, there is no wind-blown sand within the area proposed for system installation. 3. Suitable Soil Depth. Soil pits excavated support an absorption system depth up to 48”. However, proposed design will be standard trenches to be installed no deeper than 24” resulting in a minimum three-foot separation to water table. Caliche layers were identified in four of the soil exploration pits evaluated, at a depth of 60” or 66”. 4. Ground Water Requirements. a. Ground water was encountered at 61” – 108” below grade in the proposed area. b. There are no known curtain drains within 100 feet of the proposed absorption system. 5. Ground Slope. Slopes in the area proposed for the absorption system range from 1 - 2%. Slopes in the proposed replacement area are similar. 6. Other Factors Affecting LUWD System Feasibility. a. There are no rivers, streams, creeks, dry or ephemeral washes, lakes, canals, marshes, subsurface drains, natural storm water drains, lagoons, or artificial impoundments (existing or proposed) that will affect the system as proposed. b. The proposed system complies with setbacks in R317-4-13 Table 2. c. There is no floodplain within the area of the proposed wastewater system. 7. Unsuitable. No site conditions were observed through evaluation and system design work completed that would prohibit system feasibility from being issued. The area tested and proposed for the absorption system is believed to be a suitable location for an absorption system dispersing treated effluent from a packed bed media treatment system as proposed. We request that upon reviewing this report, the Approval-in-Concept be issued for flows up to 35,000 gpd (all of Phase 1 including a and b) based on the information contained herein. Construction design plans and report will clarify whether or not the interim phase 1a shall be built.

Mr. Fred Duberow Ensign Engineering 45 West 10000 South, Suite 500 Sandy, Utah 84070 Mr. Duberow: Re: Letter On-Site Wastewater Percolation Testing Proposed Tooele Valley Inland Port Wastewater System South of Burmester Road and I-80, Tooele Valley, Utah (40.673244°, -112.440389°) Introduction On April 17 and 18, 2024, a representative from GSH Geotechnical, Inc (GSH) visited the above-referenced site to perform a total of 13 wastewater percolation tests. The general location of the site with respect to existing roadways, as of 2024, is presented on Figure 1, Vicinity Map. A more detailed image of the site showing the proposed wastewater percolation test locations and proposed site features is presented on Figure 2, Site Plan. GSH understands that the on-site waste-water disposal system design will be performed by others. Subsurface Soil The following paragraphs provide generalized descriptions of the subsurface profiles and soil conditions encountered within the test pits conducted during this study. As previously noted, soil conditions may vary in unexplored locations. The test pits were excavated to depths ranging from 11.0 to 13.5 feet. The soil conditions encountered in each of the test pits, to the depths explored, were generally similar across the test pit locations. • Approximately 6 inches of topsoil was encountered in Test Pit TP-11. Topsoil thickness is frequently erratic and thicker zones of topsoil should be anticipated. Ensign Engineering Job No. 0321-17A-24 Letter – On-Site Wastewater Percolation Testing Proposed Tooele Valley Inland Port Wastewater System May 1, 2024 Page 2 • Natural soils were encountered below the ground surface in each test pit. The natural soils consisted primarily of clay with varying silt, sand, and gravel content. Occasional layers of silty/clayey sand were encountered at the surface of Test Pits TP-2 and TP-3 and at depths of approximately 10 to 12 feet in Test Pits TP-3, TP-6, TP-7, TP-8, TP-9, TP-11. Additionally, layers of caliche 12 to 18 inches thick were encountered in some of the test pits. The natural clay soils were soft to very stiff and slightly moist to saturated. The natural sand soils were loose to medium dense and slightly moist to saturated. For a more descriptive interpretation of subsurface conditions, please refer to Figures 3A through 3M, Test Pit Logs. The lines designating the interface between soil types on the test pit logs generally represent approximate boundaries. In situ, the transition between soil types may be gradual. Summary Percolation testing and exploration test pits were conducted by Mr. Tristen Leberknight, EIT, and under the supervision of Mr. Mike Huber, PE, both of GSH. Percolation tests were completed at depths ranging from 18 to 50 inches below ground surface in shallow test pits adjacent to the deeper exploration test pits (Figures 3A through 3M, Test Pit Logs). Results of the percolation testing are summarized on the table below and the corresponding percolation certificate is included as Attachment 1: Test No. Depth (inches) Soil Type (USCS) Saturation Period (hrs) Swell Period (hrs & min) Final Percolation Rate (min/in) Pass/Fail (Y/N) P-1 46 CL 4 hrs 19 hrs 31 min 30.0 Y P-2 50 SP/SM 17 hrs 11 min 0.74 N P-3 48 SM 16 hrs 0 min 0.46 N P-4 48 CL 17 hrs 33 min 3.3 Y P-5 18 CL 19 hrs 2 min 10.0 Y P-6 46 CL 17 hrs 30 min 5.0 Y P-7 20 CL 18 hrs 55 min 10.9 Y P-8 46 CL 15 hrs 58 min 2.0 Y P-9 48 CL 18 hrs 27 min 8.6 Y P-10 26 CL 17 hrs 30 min 34.3 Y P-11 30 CL 19 hrs 26 min 9.6 Y P-12 20 CL 19 hrs 43 min Failed Slow N P-13 42 CL 19 hrs 22 min 10.9 Y Ensign Engineering Job No. 0321-17A-24 Letter – On-Site Wastewater Percolation Testing Proposed Tooele Valley Inland Port Wastewater System May 1, 2024 Page 3 Closure If you have any questions or would like to discuss these items further, please feel free to contact us at (801) 685-9190.
