January 27, 2022

Equipping Well #5 (WS005)
1. This project is comprised of equipping Stansbury Park Improvement District’s new Well
#5. The new well pump, well discharge piping, and tablet chlorinator will be housed
within a new well house located near the intersection of Church Road and Old Ranch Road
in Stansbury Park, Utah.
2. The well will be equipped with a new 400-horsepower vertical turbine pump with
maximum pumping capacity of 2,500 gallons per minute (gpm). The pump will be
equipped with a variable frequency drive (VFD). The proposed intake for the pump is
approximately 250 feet below ground surface.
3. The well discharge piping will include a Rossum sand tester, an automatic backwashing
screen filter for sand removal, a magnetic flow meter, a new turbidimeter, and other valves
and appurtenances. The discharge piping will also connect to a valved pump-to-waste line
which will discharge into a detention basin outside the well house.
4. A 1.5-inch diameter water line will pull water from the well discharge piping downstream
of the sand filter and supply the new tablet chlorinator solution tank. Another 1.5-inch
diameter line will return the chlorinator water to the well discharge line just upstream of
where the piping enters the floor and flows out of the building.
5. A new Horizon Model PTF-100 tablet chlorinator will be installed inside the new well
house.
6. Well #5 will not be connected to the water system’s distribution system as part of this
project. A future water line project will connect to well discharge piping to a proposed 16-
inch diameter ductile iron pipe and into the distribution system.
7. This well is identified as WS005 in the Division’s database.

Installing Well #5 Tablet Chlorinator (TP005)
1. The proposed Well #5 Tablet Chlorinator is a tablet chlorinator using Horizon PT 90
trichloroisocyanurate (trichlor) tablets.
2. This chlorinator will add chlorine to the water from Well #5 (WS005).
3. This chlorinator is only intended to provide voluntary disinfection and to help maintain the
chlorine residual within Stansbury Park Improvement District’s distribution system. This
chlorinator is not intended to provide primary or secondary disinfection.
4. The proposed Well #5 and Well #5 Tablet Chlorinator will be connected directly to the
distribution system (DS001) in a future project.
5. The proposed Horizon PT 90 tablets meet the ANSI/NSF 60 standard.
6. The proposed design target dose of 0.3 mg/L or ppm (measured as free chlorine) is based
on an anticipated flow of 2,500 gpm from Well #5 (WS005).
7. The chlorine dose will be adjusted by an automatic flow-paced control.
8. This chlorinator is identified as TP005 in the Division’s database.

Plan Review Information

We have received the following information for Well #5 and Well #5 Tablet Chlorinator:

1. Certification of well seal.
2. Well driller’s report (well log).
3. Aquifer drawdown test results (step drawdown test and constant-rate test).
4. New Source Chemical Analyses of the well water.
5. Plans and specifications for equipping the well.
a. Pump specifications and pump curve.
b. Well head discharge piping.
c. Well house design plans and specifications.
d. Chlorinator design plans and specifications.

Plan Approval

We have completed our review of the plans and specifications, stamped and signed by Eric W.
Neil, P.E., dated October 27, 2021, and find they basically comply with the applicable portions of
Utah’s Administrative Rules for Public Drinking Water Systems in R309. On this basis, the plans
for equipping Well #5 (WS005) and installation of the Well #5 Tablet Chlorinator (TP005)
are hereby approved.

This approval pertains to construction only. An Operating Permit must be obtained from the
Director before Well #5 and the Well #5 Tablet Chlorinator may be put in service. A
checklist outlining the items required for operating permit issuance is enclosed for your
information.

Approvals or permits from the local authority or county may be necessary before beginning
construction of this project. As the project proceeds, 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 equipment has not
been ordered within one year of the date of this letter.

Disinfection Requirements

Stansbury Park Improvement District is not currently required to disinfect Well #5 (WS005) based
on bacteriological source sample results currently available. The water system proposes to
voluntarily install the Well #5 Tablet Chlorinator (TP005) to help maintain a detectable chlorine
residual in the distribution system. The Well #5 Tablet Chlorinator will use Horizon PT 90
trichloroisocyanurate (trichlor) tablets. Per Division of Drinking Water policy, trichlor based
disinfectants cannot be used to provide primary or secondary disinfection. If the Well #5
Brett Palmer
Page 4 of 6
January 27, 2022

(WS005) source is ever determined to require primary or secondary disinfection, the Well
#5 Tablet Chlorinator will need to be modified or replaced to comply with Division policy.

1. Chlorine Residual ‒ Distribution System (DS001)
a. This water system will be required to maintain a detectable residual throughout the
distribution system. It is recommended to maintain the chlorine residual above 0.1
ppm in the distribution system. [R309-520-5]
b. The chlorine residual measured in the distribution system must not exceed the
maximum residual disinfectant level (MRDL) of 4.0 mg/L (measured as free
chlorine). [R309-200-5(3)(c)(iv)]
c. This water system will be required to take a minimum of three (3) chlorine
residual samples per week at varying locations throughout its distribution
system (DS001). [R309-105-10(1)(c)]
d. Take distribution system chlorine residuals in conjunction with total coliform
sampling. [R309-215-10(3) and (4)]

2. Chlorine Residual ‒ The Point of Entry to Distribution System (EP005)
a. The requirements 2.b through 2.e below will go into effect when the Well #5
Tablet Chlorinator (TP005) is permitted to be connected to the system and put into
use.
b. The Point of Entry (POE) sampling location for the Well #5 Tablet Chlorinator
(TP005) will be determined when the chlorinator is connected to the distribution
system and put into use. Once determined, this POE sampling location will be
identified as EP005 in the Division’s database.
c. This water system will be required to maintain a minimum of 0.2 mg/L residual
(measured as free chlorine) at the POE sampling location. [R309-215-5(3) and
R309-215-10(2)]
d. The chlorine residual measured at the POE sampling location must not exceed the
maximum residual disinfectant level (MRDL) of 4.0 mg/L (measured as free
chlorine). [R309-200-5(3)(c)(iv)]
e. This water system will be required to record and report the free chlorine residual at
the Well #5 Tablet Chlorinator (TP005) POE sampling location (EP005) a
minimum of 3 days a week. [R309-210-8(3)(a)(ii)]

Source Protection Requirements

The Drinking Water Source Protection (DWSP) plan for Well No 5 (WS005) was due September
25, 2018. You must submit copies of Land Use Agreements that have been recorded with Tooele
County or proof that the delineation has been submitted to Tooele County to be covered under the
Tooele County Source Protection Ordinance before the well can receive an operating permit.

Temporary Exception to R309-520-7(1)(c) Chlorine Feed Capacity

R309-520-7(1)(c) Chlorine Feed Capacity states:
1. The capacity of the chlorine feed equipment shall be sized to provide at least 2 mg/L
during peak demand.
2. The feed equipment shall operate accurately over the design feeding range.
3. The feed equipment shall be designed to maintain a detectable residual at all times, at all
points within the intended area in the distribution system.

The basis for your request for an exception to R309-520-7(1)(c) is that due to the 2,500 gpm
design flow rate of Well #5 and the anticipated chemical dose of 0.2 to 0.4 mg/l, meeting the 2
mg/L requirement during peak demand would require a robust dosing pump that may not
efficiently operate at the lower range of the dosing pump capacity. You propose public health is
protected and the intent of the rule is met according to the following:
1. The dosing pump will be able to maintain a 0.2 mg/L chlorine residual at the Point-of-
Entry (POE) sampling location during peak flow.
2. The dosing pump can maintain a 0.1 mg/L chlorine residual within the distribution system
during peak flow.
3. Well #5 (WS005) is not currently required to be treated for primary or secondary
disinfection.

On this basis, an exception to R309-520-7(1)(c) Chlorine Feed Capacity, is hereby granted for
Well #5 Tablet Chlorinator (TP005).

1. This Temporary Exception expires on January 31, 2025.

2. You will be required to re-submit an exception request along with confirmation that all
conditions outlined in this temporary exception have been fulfilled and obtain an
exception renewal prior to January 31, 2025.

a. Exceptions granted by the Division include an expiration date to ensure that the
basis and conditions for granting the exception are verified periodically and that
the drinking water quality remains protected. After receiving your request, the
Division will determine whether this exception can be re-issued.

b. Failure to request the re-evaluation of this exception and obtain an exception
renewal by January 31, 2025, will result in the activation of the deficiency related
to not having an adequate means to maintain the disinfectant residual in the water
entering the distribution system.

3. This Temporary Exception may be rescinded any time if new evidence indicates that
the conditions of this exception are no longer being met or a public health risk exists
due to this exception.
