Subject: 2025 Renewal System-Specific Minimum Sizing Standards—Final Determination
American Fork City, System #25008, File #11594

Dear Jay Brems:

DETERMINATIONS

Based on the findings set forth below, the Division of Drinking Water (the Division) hereby
establishes the following system-specific minimum sizing standards for American Fork City (the
System):

Peak Day Source Demand (gallons/day/ERC) – 743
Average Annual Demand (gallons/year/ERC) – 140,208
Equalization Storage (gallons/ERC) – 384
Fire Storage (gallons) – 675,000

Introduction

Pursuant to Utah Code Section 19-4-114, the Director of the Division (Director) is required to
establish system-specific minimum sizing standards based on, among other factors, water use data
submitted to the Division of Water Rights (DWRi). The Director’s determinations may also be
based on engineering analyses and other evidence if this is available. This final determination
letter is addressed to you in your capacity as the Administrative Contact for the System. The
Director has delegated the responsibility for making system-specific minimum sizing standards
under Utah Code Section 19-4-114 to the Engineering Manager for the Division.

Prior to issuing this final determination letter, the Division analyzed applicable DWRi water use
data and sent a draft summary of the Division’s proposed system-specific minimum sizing
standards to the System on November 13, 2024. The Division sent a followup email about the
minimum sizing standards on January 27, 2025. The Division allowed for 30 days for the System
to review the draft system-specific minimum sizing. The System concurred with the draft system-
specific minimum sizing on February 10, 2025. A summary of the water use data and calculations
the Division used to make these determinations is attached as part of the administrative record.

Water Use Data Definitions

As used in this Final Determination, the following terms have the following meanings:
Peak Day Source Demand is the total flow into a public water system to meet the demand of the
water system on the day of the highest water consumption in a calendar year.

Average Annual Demand is the total quantity of drinking water flowing into a public water system
within a calendar year.

Total Equivalent Residential Connections (ERCs) term represents the number of residential
service connections and the number of equivalent residential connections for non-residential
connections (commercial, industrial, institutional connections).

Minimum Equalization Storage requirement is a volume that is equivalent to the amount of water
needed to meet the average day culinary demand for public water systems. Equalized storage per
ERC is calculated by dividing the Average Annual Demand per ERC data by the number of
operational days in a year.

Water System Background Facts

The System is a community water system in Utah County. The system currently has 10,735
residential connections serving an approximate population of 38,005 residents. Additionally, the
System provides water to 705 commercial, 3 industrial, and 53 institutional connections. The
System operates and maintains ten (10) active sources, two (2) springs and eight (8) wells, and
three (3) storage tanks with the associated distribution lines. Additionally, about eight (8)
connections of American Fork are served through Cedar Hills (UTAH25137) since the System
does not have distribution lines to provide service.

System-Specific Minimum Sizing Standards—Background

Under Utah Code Section 19-4-114, the legislature required that the Director establish minimum
sizing standards on a system-specific basis instead of statewide, as the Division has done in the
past. System-specific determinations need to be based on system-specific information. The code
allows the Director to rely on water use data submitted to DWRi. Alternatively, a community
water system may perform and submit an engineering study to the Division if the water system’s
water use data is not representative of future use or the water system does not yet have actual
water use data. In this matter, actual water use data was available through DWRi, and an

engineering study was not submitted to the Division for review. Therefore, the Division has relied
upon DWRi information and other relevant data.

Additional System-Specific Basis for Determinations

The Division established Fire Storage requirements based on information from Mat Sacco on July
30, 2020 who was at that time the Fire Marshal for American Fork Fire & Rescue.

Storage Capacity

Based on the System’s storage facilities and the storage minimum sizing requirement established
in this letter, the Director hereby determines that the System is compliant with the minimum
storage capacity requirements.

Source Capacity

The Division has adequate documentation of established safe yields (wells) and yields (springs)
for all the System’s sources. Using total system-wide safe yields and yields and the source
minimum sizing requirement established in this letter indicates that the System is compliant with
minimum source capacity requirements.

Effective Date

The determinations made in this letter are effective immediately and will become final 30 days
from the date of this letter unless the System files a contest as provided below.

Notice of Right to Contest

The Director has determined this determination made under Section 19-3-114 qualifies as a
“permit order” within the meaning of Utah Code Section 19-1-301.5(1)(f). See Utah Code § 19-1-
301.5(1)(e) (defining “permit” to include a “plan” or “other administrative authorization”).

The System may contest any determinations made herein by delivering a notice of contest to the
Director. The notice of contest must be in writing and must be delivered to the Director on or
before 30 days after the date this letter is signed. There is no particular form for the notice of
contest, but it must include the System’s reasons and rationale for the contest. The Director’s
address for purposes of submitting a notice of contest is as follows:

U.S. Mail

Attention: Director

Email

A notice of contest may be submitted to the Director by email, provided, however, that the
Director confirms receipt of the email. The Director’s email address is:
[e-mail]. The email submission must be received by the Director before the
expiration of the contest deadline.

If the System files a timely notice of contest, the Director will evaluate the matter and attempt to
resolve the matter through negotiations. If the Director is not able to resolve the matter, the
Director will issue a final agency action regarding the contest. At that point in the process, the
System shall have the right to seek further internal agency and judicial review pursuant to Utah
Admin. Code R305-7 and Utah Code Section 19-1-301.5.

Right to Request Reconsideration

The Director plans to evaluate the determinations made herein every three years. However, this
requirement is not mandatory. At any time, a water system whose system-specific minimum
sizing standards have been established by the Division under Section 19-4-114 may request
reconsideration of the Director’s determinations by submitting a written request. A request for
reconsideration shall be submitted to the Director in the same manner as a notice of contest
provided above.

Conclusion

If the System management has any questions regarding this letter, please contact Dani Zebelean,
P.E., of this office, at [phone], or me at [phone].

Sincerely,

Michael Newberry, P.E.
Permitting and Engineering Support Manager
