Section 401 Water Quality Certification No. DWQ-2024-12001Project Proponents:Bret SheffieldVTRE DEVELOPMENT LLCExecutive Vice President, Development Service136 South Main Street, Suite
400 Salt Lake City, UT, 84101
Project:VTRE Development LLC (Project Proponent) proposes constructing an industrial development consisting of four warehouses, access roads, parking, and utilities for the West Valley
City Beagley Road Industrial Development (Proposed Project). This 41-acre site is located at 5902 West Beagley Road in West Valley City, Utah, adjacent to the Mountain View Corridor
and Beagley Road. The Project Proponent asserts that the industrial development will foster job market growth and address the needs of West Valley City's development. Construction of
the four industrial warehouses totaling 606,000 square feet, parking, docking, and vehicle access to the warehouses to connect to all site access points from Beagley Road will permanently
impact 4.05 acres of Waters of the United States (WOTUS) located on the property. The Proposed Project requires the realignment of Riter Canal, which bisects the property flowing from
the east to the west. Approximately 2,035 linear feet (0.94 ac) of Riter Canal and 657 linear feet (0.12 ac) of flood channel on the north side of the property will be filled as a result
of the Proposed Project. Additionally, the Proposed Project will involve filling approximately 1.95 acres of saline wet meadow, 0.24 acres of playa, 0.74 acres of phragmites fringe wetlands,
and 0.15 acres of a pond on the site. The Project Proponent estimates that about 34,658 cubic yards of clean fill material will be used to fill the wetlands, ponds, and the realignment
of Riter Canal.
The applicant asserts that all reasonable and practical measures will be taken to avoid and minimize impacts on aquatic resources. Compensatory mitigation will be required. The applicant
has proposed purchasing credits from Machine Lake Mitigation Bank for the aquatic resource losses.

Executive Summary
Pursuant to Section 401 of the CWA 33 U.S.C. Section 1251 et seq., the DWQ grants Water Quality Certification (Certification) to Summit County for the proposed Summit County SR-32 Trail
Marion to Kamas Project in Summit County, Utah.Certification is subject to the conditions outlined in this document and adherence to any U.S. Army Corps of Engineers (USACE) Section
404 Permit Conditions. The conditions outlined in this Certification are necessary to assure compliance with effluent limitations, monitoring requirements, and/or other applicable laws
and regulations adopted for state primacy of the CWA.
DWQ’s conditions are based on and are necessary to comply with applicable state rules. Specifically, the following Utah rules represent overarching considerations that require the conditions
outlined by this document to apply to the USACE Section 404 Permit: Utah’s rules promulgating standards of quality for waters of the State affirm “it shall be unlawful and a violation
of these rules for any person to discharge or place any wastes or other substances in such manner as may interfere with designated uses protected by assigned classes or to cause any
of the applicable standards to be violated” UAC R317-2-7.1.a. Additionally, “all actions to control waste discharges under these rules shall be modified as necessary to protect downstream
designated uses” UAC R317-2-8. As stated in UAC R317-15-6.1 the Director will ordinarily consider whether the proposed discharge “impairs the designated beneficial use classifications
(e.g., aquatic life, drinking water, recreation) in Section R317-2-6” UAC R317-15-6.1.A.1., “exceeds water quality criteria, either narrative or numeric, in Section R317-2-7” UAC R317-15-6.1A.2.
or “fails to meet the antidegradation (ADR) requirements of Section R317-2-7” UAC R317-15-6.1.A.3.
On October 22, 2024, DWQ attended a pre-filling meeting with Merissa Davis and Cara Glabau from Bowen and Collins on behalf of Bret Sheffieldfrom VTRE Development LLC for the Proposed
Project.On December 30, 2024Merissa Davissubmitted a complete Water Quality 401 Certification Application to DWQ for the Proposed Project.On February 6, 2025,Hollis Jencks with the USACE
Sacramento District established the reasonable period of time for a Certification decision would be 6 months from January 8, 2025. This requires that the Director act by July 8, 2025.

Background
Project Introduction
VTRE Development LLC (the Project Proponent) proposes the construction of an industrial development known as the West Valley Beagley Road Industrial Development (Proposed Project). This
industrial development will consist of four separate warehouses, along with access roads and parking facilities. The project is located on a 41-acre lot at approximately 5902 West Beagley
Road in West Valley City, Salt Lake County, Utah. The Mountain View Corridor lies adjacent to the east, while Beagley Road borders the property to the north.
The Project Proponent has indicated that this area has become crucial for the growing industrial and manufacturing sector due to its proximity to the Salt Lake International Airport
and rail lines. Currently, West Valley City has an estimated 7 million square feet of industrial space within its boundaries, with one-third of all land in the city developed for commercial
or industrial use. Consequently, the city is encouraging industrial and office development through its land use strategies, aiming to expand the local economy and job market through
industrial growth. The Project Proposal asserts that this development will further the City’s goals of bolstering industrial and office development, and benefit the City’s economy. The
project site is currently undeveloped land, with approximately half being used as open range for various livestock.
Impacts
The construction of the four industrial warehouses, totaling 606,000 square feet, along with parking, loading docks, and vehicle access points, will result in permanent impacts to 4.05
acres of WOTUS located on the property. The Proposed Project requires the realignment of Riter Canal, which bisects the property from east to west. The canal will be relocated to the
north side of the property, adjacent to Beagley Road, and will be reconnected to the existing canal, which discharges into the Great Salt Lake. Currently, several wells from the Magna
Water District drain through the site into the Riter Canal. As part of the Proposed Project, an open drainage channel will be constructed across the property to maintain drainage from
the Magna Water District wells to the realigned Riter Canal. Approximately 2,035 linear feet (0.94 acres) of Riter Canal and 657 linear feet (0.12 acres) of flood channel on the north
side of the property will be filled as a result of the project.
Additionally, wetlands and ponds on the site, some of which are isolated while others connect to the Riter Canal, will also be permanently filled for this project. The Proposed Project
will involve filling approximately 1.95 acres of saline wet meadow, 0.24 acres of playa, 0.74 acres of phragmites fringe wetlands, and 0.15 acres of a pond located on the property. The
Project Proponent estimates that around 34,658 cubic yards of clean fill material will be necessary for the wetland areas, ponds, and the realignment of Riter Canal.
Mitigation/Minimization
The Project Proponent evaluated several alternatives for the project. The Proposed Project was determined to be the best option to minimize aquatic impacts while fulfilling the project's
needs. The proposed realignment of Riter Canal will closely resemble the existing canal, featuring earthen banks with a 2:1 slope, and the banks will be reseeded with native plant species.
Equipment used to excavate the new canal alignment will be clean, and appropriate construction Best Management Practices (BMPs) will be employed to protect the downstream portion of
the canal that will not be affected. These measures should ensure that water quality is not compromised. The contractor chosen for this project will be responsible for obtaining any
required UPDES General Permits for stormwater and/or construction dewatering.
To address the aquatic resource losses, the Project Proponent plans to purchase mitigation credits from the Machine Lake Mitigation Bank in Brigham City, Utah. Impacts to the Riter Canal
and associated fringe wetlands will be compensated with in-kind mitigation along the realigned section of the canal. This realignment will be designed to reduce potential erosion compared
to current conditions and lessen the steepness of the banks, facilitating the development of new fringe wetlands. The Corps will collaborate with the Project Proponent to establish the
appropriate mitigation required for the Proposed Project.
Aquatic Resource Impacts

All Waters of the State of Utah (defined in UAC R317-1-1) are protected from pollutant discharges that affect water quality by narrative standards (see UAC R317-2-7.2); broadly, discharges
should not become offensive or cause undesirable conditions in human health effects or aquatic life. In addition, some particularly sensitive classes of water are further protected from
deleterious effects of specific pollutants by application of numeric criteria to designated beneficial uses of that waterbody. Listed below are the water features, grouped by AUs, impacted
by the Project, their associated designated beneficial uses (see UAC R317-2-6 and UAC R317-2-13) and any impairments:Riter Canal, unnamed channel and pond located in an undefined AUwithin
the Great Salt Lake WatershedBeneficial Use Designations
Class 2B: Protected for infrequent primary contact recreation. Also protected for secondary contact recreation where there is a low likelihood of ingestion of water or a low degree of
bodily contact with the water. Examples include, but are not limited to, wading, hunting, and fishing.
Class 3D: Protected for waterfowl, shore birds and other water-oriented wildlife not included in Classes 3A, 3B, or 3C including the necessary aquatic organisms in their food chain.
Impairments and TMDLs: N/A
Antidegradation Review Waters within the undefined AU within the Great Salt Lake Watershedare considered a Category 3 water for antidegradation purposes. Category 3 waters in Utah are
waters where“point source discharges are allowed and degradation may occur, pursuant to the conditions and review procedures outlined in Section 3.5”, as described in UAC R317-2-3.4.
The antidegradation policy allows for discharges where the water quality effects of the proposed Project are determined to be temporary and limited after consideration of the factors
identified in UAC R317-2-3.5.b.4., and where BMPs would be employed to minimize pollution effects.

Antidegradation Review Wetlands are considered a Category 3 water for antidegradation purposes. Category 3 waters in Utah are waters where“point source discharges are allowed and degradation
may occur, pursuant to the conditions and review procedures outlined in Section 3.5”, as described in UAC R317-2-3.4. The antidegradation policy allows for discharges where the water
quality effects of the proposed Project are determined to be temporary and limited after consideration of the factors identified in UAC R317-2-3.5.b.4., and where BMPs would be employed
to minimize pollution effects.
Certification Conditions
All activities with a potential discharge to WOTUS must implement and maintain BMPs to fully protect the waterbodies assigned beneficial use(s).
Hazardous and otherwise deleterious materials (e.g. oil, gasoline, chemicals, trash, sawdust, soil, etc.) shall not be stored, disposed of, or accumulated or conveyed through adjacent
to or in immediate vicinity WOTUS unless adequate measures and controls are provided to ensure those materials would not enter WOTUS in the State of Utah. Any spill or discharge of oil
or other substance which may cause pollution to WOTUS in the State of Utah, including wetlands, must be immediately reported to the Utah DEQ Hotline at [phone], a 24-hour phone
number.
All activities conducted in WOTUS in the State of Utah shall be conducted in the “dry” to the maximum extent practicable, by diverting flow utilizing cofferdams, berms constructed of
sandbags, clean rock (containing no fine sediment) or other non-erodible, non-toxic material. All diversion materials shall be removed at the completion of the work. The Project Proponent
shall consider conducting instream work during low flow conditions and work shall not be conducted during spawning season. Additionally, construction machinery shall not be operated
within WOTUS in the State of Utah unless it is unavoidable, in which case it shall be conducted in the “dry” as stated above. The work shall be conducted in a manner to minimize the
duration of the disturbance, turbidity increases, substrate disturbance, and minimize the removal of riparian vegetation. Construction machinery shall be clean to prevent the transfer
of aquatic invasive species.
Project activities shall not increase water turbidity by more than 10 Nephelometric Turbidity Units (NTUs) in waterbodies classified as beneficial use class 2B for recreation and 3A
for cold water aquatic life. Project activities shall not cause an increase in water turbidity by more than 15 NTUS in waterbodies classified as beneficial use class 3D. Project Proponents
must continuously monitor turbidity during instream construction to ensure turbidity increases are within the limits listed above. The Project Proponents must provide monthly reports
to DWQ during instream construction in waterbodies with class 2B, 3A, and 3D beneficial use designations that include at a minimum: baseline (reference) turbidity measurements in each
waterbody where instream construction is occurring.
Construction activities that disturb either greater than one acre of land, or less than one acre of land and is part of a larger common plan of development that would disturb greater
than one acre, are required to obtain coverage under the Utah Pollutant Discharge Elimination System (UPDES) Storm Water General Permit for Construction Activities (Permit No. UTRC00000[]).
The permit requires the development of a Storm Water Pollution Prevention Plan (SWPPP) to be implemented and updated from the commencement of any soil disturbing activities at the site,
until final stabilization of the project. The SWPPP should include, but not be limited to, final site maps and legible plans, location of storm water outfalls/discharges, and information
pertaining to any storm water retention requirements.
Dewatering activities, if necessary during construction, may require coverage under the UPDES General Permit for Construction Dewatering (Permit No. UTG070000[]) applies to the construction
dewatering of uncontaminated groundwater or surface water sources due to construction activities; hydrostatic testing of pipelines or other fluids vessels; water used in disinfection
of drinking water vessels; and other similar discharges in the State of Utah that have no discharge of process wastewater. The permit requires submission of a Notice of Intent (NOI);
maintenance of a discharge log; development and implementation of a dewatering control plan; and monitoring for Flow, Oil & Grease, pH, Total Suspended Solids (TSS), and Chlorine (required
when chlorinated water is used and discharged to a stream with a chlorine standard). Discharge Monitoring Reports (DMRs) are required to be submitted monthly, regardless of whether a
site discharges in a particular month.
Condition Justification and Citation
Implementation of BMPs. Project approval is conditioned on implementation of BMPs, which are required to be implemented by the antidegradation policy in UAC R317-2-3, water quality standards
may be violated unless appropriate BMPs are incorporated to minimize the erosion-sediment and nutrient load. Violations of water quality standards could cause a waterbody to fail to
meet its designated beneficial uses. As required by Utah’s antidegradation policy UAC R317-2-3.1 “Existing instream water uses shall be maintained and protected. No water //quality degradation
is allowable which would interfere with or become injurious to existing instream water uses.” As stated in UAC R317-15-6.1 the Director will ordinarily consider whether the proposed
discharge “impairs the designated beneficial use classifications (e.g., aquatic life, drinking water, recreation) in Section R317-2-6” UAC R317-15-6.1.A.1., “exceeds water quality criteria,
either narrative or numeric, in Section R317-2-7” UAC R317-15-6.1A.2. or “fails to meet the antidegradation (ADR) requirements of Section R317-2-7” UAC R317-15-6.1.A.3 when making a
Certification decision. If appropriate BMPs are incorporated, there is assurance that the Project will not violate water quality standards or impair a waterbody’s beneficial use.

Proper Storage of Hazardous and Otherwise Deleterious Materials. Project approval is conditioned on proper storage of hazardous and otherwise deleterious materials, and notification
of any discharge of those materials, to assure that water quality and narrative standards are not violated. When projects are occurring in or around waterbodies, there is a chance for
pollutants to inadvertently be spilled/discharged into waterbodies due to increased risk from project related activities (e.g. presence of machinery, onsite chemical and gas storage,
improper waste storage, and failure to use proper BMPs). To prevent or reduce the possibility that hazardous and otherwise deleterious materials are inadvertently discharged into a waterbody,
Project Proponents must not store, dispose of, or accumulated such materials adjacent to or in immediate vicinity of WOTUS unless adequate measures and controls are provided to ensure
those materials would not enter waters of the State. If there is a discharge to WOTUS in the State of Utah, it must be immediately reported to the DEQ, as stated in Utah Code Section
19-5-114. An inadvertent discharge of pollutants can cause violations with Utah’s Narrative Standards, which states “It shall be unlawful, and a violation of these rules, for any person
to discharge or place any waste or other substance in such a way as will be or may become offensive such as unnatural deposits, floating debris, oil, scum or other nuisances such as
color, odor or taste; or cause conditions which produce undesirable aquatic life or which produce objectionable tastes in edible aquatic organisms; or result in concentrations or combinations
of substances which produce undesirable physiological responses in desirable resident fish, or other desirable aquatic life, or undesirable human health effects, as determined by bioassay
or other tests performed in accordance with standard procedures; or determined by biological assessments in Subsection R317-2-7.3” UAC R317-3-7.2. Utah’s rules promulgating standards
of quality for waters of the State affirm “it shall be unlawful and a violation of these rules for any person to discharge or place any wastes or other substances in such manner as may
interfere with designated uses protected by assigned classes or to cause any of the applicable standards to be violated” UAC R317-2-7.1.a. Discharges of pollutants, even inadvertently,
could cause both a violation of applicable water quality standards and possibly interfere with a waterbodies designated uses.

Dry Conditions to the Maximum Extent Practicable. Project approval is conditioned on conducting activities under dry conditions to the maximum extent practicable to assure that water
quality standards are not exceeded. Construction machinery used within a waterbody can cause significant impacts to water quality if adequate precautions are not taken. When it is unavoidable
to operate construction machinery within the waterbody the Project Proponent should focus on minimizing the duration of the disturbance, turbidity increase, substrate disturbance, removal
of riparian vegetation, and work shall be conducted in the “dry” to the maximum extent practicable. Minimizing the duration of impact reduces the chance that the impacts will accumulate
and cause significant impacts to water quality. Minimizing turbidity increases is important because the State of Utah has numeric water quality criteria for turbidity in certain use
designations, which could be violated if the Project Proponent does not take proper steps to minimize the increases. Water quality criteria for turbidity will be violated if there is
an increase of 10 NTUs in waterbodies with designated uses related to recreation and if there is an increase of 10 NTUs (class 3A and 3B) or 15 NTUs (class 3C and 3D) in waterbodies
with aquatic wildlife designated uses. UAC R317-2-14.1 and UAC R317-2-14.2. Conducting work in the “dry” to the maximum extent practicable will help reduce the risk of the numeric criteria
for turbidity to be exceeded, as well as reduce the risk of a significant sediment load being transported downstream. Discharges of sediment can not only violate numeric criteria, but
also, risk violating Utah’s narrative standard “It shall be unlawful, and a violation of these rules, for any person to discharge or place any waste or other substance in such a way
as will be or may become offensive such as unnatural deposits, floating debris, oil, scum or other nuisances such as color, odor or taste; or cause conditions which produce undesirable
aquatic life or which produce objectionable tastes in edible aquatic organisms; or result in concentrations or combinations of substances which produce undesirable physiological responses
in desirable resident fish, or other desirable aquatic life, or undesirable human health effects, as determined by bioassay or other tests performed in accordance with standard procedures;
or determined by biological assessments in Subsection R317-2-7.3.” UAC R317-2-7.2. Violations of numeric and narrative criteria could cause a waterbody not to meet its designated beneficial
use and a transport of sediment downstream could prevent a downstream waterbody from meeting its designated beneficial uses. As required by Utah’s antidegradation policy UAC R317-2-3.1
“Existing instream water uses shall be maintained and protected. No water quality degradation is allowable which would interfere with or become injurious to existing instream water uses”.
Additionally, “All actions to control waste discharges under these rules shall be modified as necessary to protect downstream designated uses” UAC R317-2-8. As stated in UAC R317-15-6.1
the Director will ordinarily consider whether the proposed discharge “impairs the designated beneficial use classifications (e.g., aquatic life, drinking water, recreation) in Section
R317-2-6” UAC R317-15-6.1.A.1., “exceeds water quality criteria, either narrative or numeric, in Section R317-2-7” UAC R317-15-6.1A.2. or “fails to meet the antidegradation (ADR) requirements
of Section R317-2-7” UAC R317-15-6.1.A.3 when making a certification decision.

UAC R317-15-6.1A.2., UAC R317-15-6.1.A.3.
Turbidity Increases and Instream Construction Monitoring. Beneficial uses associated with recreation and aquatic life have been assigned numeric criteria for turbidity. An increase of
more than 10 NTUs in class 2B and 3A waterbodies above the turbidity of that waterbody would be a violation of instream criteria for waterbodies that have recreation or aquatic life
uses. Similarly, an increase of more than 15 NTUs in class 3D waterbodies above the turbidity of that waterbody would be a violation of instream criteria for waterbodies that have aquatic
life uses. UAC R317-2-14.1 and UAC R317-2-14.2. Therefore, turbidity increases above those allowed by this Certification could cause the waterbody to fail to meet its designated beneficial
use classes. Turbidity monitoring during instream construction in waterbodies with class 2B, 3A and 3D beneficial uses designations will ensure turbidity increases do not violate Utah’s
water quality standards. Utah’s antidegradation policy states “existing instream water uses shall be maintained and protected. No water quality degradation is allowable which would interfere
with or become injurious to existing instream water uses” UAC R317-2-3.1. Failure to minimize turbidity increases that result in the failure to maintain beneficial use class 2B or 3A
would be considered a violation of Utah’s rules and promulgated standards of quality for waters of the State, specifically Utah’s antidegradation policy found at UAC R317-2-3. The Director
will ordinarily consider whether the proposed discharge “impairs the designated beneficial use classifications (e.g., aquatic life, drinking water, recreation) in Section R317-2-6” UAC
R317-15-6.1.A.1., “exceeds water quality criteria, either narrative or numeric, in Section R317-2-7” UAC R317-15-6.1A.2. or “fails to meet the antidegradation (ADR) requirements of Section
R317-2-7” UAC R317-15-6.1.A.3 when making a certification decision.

UPDES Storm Water General Permit for Construction Activities (Permit No. UTRC00000). UAC R317-8-2.5, gives the Director authority to issue general permits to cover specific categories
of discharges, including storm water and construction dewatering that is discharged to a surface water. According to UAC R317-8-3.9 (6)(d), construction activities that result in a land
disturbance of equal to or greater than one acre, including clearing, grading, and excavation are “industrial activities” under UAC R317-8-3.9(1)(a) and are therefore required to obtain
and comply with a UPDES Permit for storm water discharges. This only applies to projects that meet or exceed one acre of disturbance.
