Dear Brett Knight:The Division of Drinking Water (the Division) received the plans and specifications for the City Hall Well and Gas Chlorinator and Transmission Line from your consultant,
Steven Wood, P.E., with Sunrise Engineering, on December 22, 2024. The Division issued After-the-Fact Plan Approval for drilling City Hall Well on August 7, 2024. Written review comments
were provided to your consultant on January 16, 2025. The Division received additional information related to the project on January 21, 2025, including constant rate drawdown test results,
new source chemical analysis results, and the well log. The City Hall Well is identified as WS004 in our database, and the City Hall Chlorinator is identified as TP002.
Project Summary for City Hall Well (WS004) and Transmission Line
Our understanding of the project is to equip City Hall Well with a 1,280 gpm pump in a new well house. The constant rate drawdown test was conducted at 1,750 gpm and reached a stable
drawdown of approximately 76 feet. The well discharge piping will include a pump-to-waste line and a new gas chlorinator which will be housed in a separate room in the new well house.
A new 12-inch diameter C900 PVC transmission line will connect the new well to the existing 1.5 MG Tank (ST005) with no service connections between the well and tank. This well is identified
as WS004 in the Division’s database.
We have received the following information for City Hall Well and Transmission Line:
Certification of well seal.
Well driller’s report (well log).
Aquifer drawdown test results (step drawdown test and constant-rate test).
New Source Chemical Analysis of the well water.
Plans and specifications for equipping the well.
Pump information.
Well head discharge piping.
Well house design.
Chlorinator design.
Project Summary for City Hall Chlorinator (TP002)
Our understanding of the project includes installing a new gas chlorination facility within the proposed City Hall Well building. The chlorinator will consist of two 150-pound chlorine
gas cylinders with an automatic switchover. The chlorinator will be housed in a separate room of the proposed City Hall Well building. The City Hall Chlorinator is identified as TP002
in our database.
The plan review of the proposed City Hall Chlorinator (TP002) has been completed according to the following:
The proposed City Hall Chlorinator is a gas chlorinator.
This chlorinator will add chlorine to the water from City Hall Well (WS004).
This chlorinator is intended to provide elective secondary disinfection in the distribution system.
Chlorinated water will flow to the 1.5 MG Tank (ST005) and then to the distribution system.
The proposed chlorine gas to be used for disinfection meets the ANSI/NSF 60 standard.
The proposed design target dose of 3.3 mg/L or ppm (measured as free chlorine) is based on a typical flow of 1,280 gallons per minute (gpm) from City Hall Well.
The chlorine dose will be adjusted by an automatic flow-paced control.
The Point of Entry (POE) sampling location will be the outlet of the 1.5 MG Tank (ST005).
Secondary Disinfection Requirements
The Hyde Park City Water Systemis not required to disinfect the City Hall Well (WS004) based on bacteriological source sample results currently available. The water system proposes to
voluntarily install the City Hall Chlorinator (TP002) to provide a detectable disinfectant residual in the distribution system for secondary disinfection.
The plan review of the proposed City Hall Chlorinator (TP002) is based on providing secondary disinfection. When this chlorinator is installed and placed in operation after the Operating
Permit issuance, the Hyde Park City Water System will be required to demonstrate ongoing compliance with the secondary disinfection requirements that are outlined in Addendum 1 to this
letter.
Plan Approval for City Hall Well, Chlorinator, and Transmission Line
We have completed our review of the plans and specifications, stamped and signed by Steven David Wood, P. E., and dated December 20, 2024, 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 construction of the City Hall Well and Chlorinator and transmission lineare
hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before City Hall Well and Chlorinator may be put into service. A checklist outlining
the well approval process, including the items required for issuing an operating permit for this well is enclosed for your information. Enclosed please also find an Operating permit
Checklist for other components of this project.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.
New Source Chemical Analysis
The initial new source chemistry data of the well water indicated turbidity level above 5 NTU. Before an Operating Permit can be issued for this source, you must re-sample for turbidity
following well equipment and submit the turbidity result to the Division as proof of meeting the MCL for turbidity. Please contact David Kruse at [e-mail] or 385-566-7789 with

Addendum 1
Future Elective Monitoring and Reporting Requirements
Chlorine Monitoring & Reporting Requirements
The water system will be required to meet elective disinfection requirements once this facility is installed and operating. As a part of these requirements, the water system will need
to continuously maintain a minimum free chlorine residual at each chlorinator Point of Entry (POE) into the system and demonstrate a detectable chlorine residual in the distribution
system.

Elective Disinfection Requirements and Reporting
Chlorine Residual ‒ Point of Entry (POE) to Distribution System
The POE sampling location will be identified in the Division’s database. The location will be identified during the plan approval process. Maintain a minimum of 0.2 mg/L residual (measured
as free chlorine) at the POE sampling location. [R309-215-16(3)(b)(iii)(A)(I) and (II)]
The chlorine residual concentration measured at the POE sampling location shall not exceed the maximum residual disinfectant level (MRDL) of 4.0 mg/L (measured as free chlorine). [R309-200-5(3)(c)(iv)]Record
and report the lowest daily value of chlorine residual measured as free chlorine at the POE sampling location (EP002). [R309-215-10(1)]Our records show that your water system serves
5,200 people. Please be aware that R309-215-16(3)(b)(iii)(A)(I) requires water systems serving greater than 3,300 people to continuously monitor the POE chlorine residuals. Therefore,
an online analyzer to continuously monitor the POE chlorine residuals entering the distribution system will be needed.
Chlorine Residual ‒ Distribution System (DS001)
This water system must maintain a detectable residualthroughout the distribution system. It is recommended to maintain the chlorine residual above 0.1 ppm in the distribution system.
[R309-520-5]
The chlorine residual measured in the distribution system shall not exceed the maximum residual disinfectant level (MRDL) of 4.0 mg/L (measured as free chlorine). [R309-200-5(3)(c)(iv)]
This water system must take a minimum of three (3) chlorine residual samples per weekat varying locations throughout its distribution system (DS001). [R309-105-10(1)(c)]
Distribution system chlorine residuals must be taken in conjunction with total coliform sampling. [R309-215-10(3)]
Disinfection Report Submission
To demonstrate ongoing compliance with elective disinfection requirements, the water system must complete monthly operational reports for each active chlorinator using a template approved
by the Division.
The monthly operational reports are submitted quarterly. The reports are due to the Division by the 10th day following the end of each reporting quarter (i.e., January 10th, April 10th,
July 10th and October 10th). The reports can be submitted by hardcopy, fax, or by uploading them to the Division’s chlorine residual reporting form which can be found at MRDL.utah.gov.
Please contact Luke Treutel at [phone] or [e-mail] to schedule training regarding proper reporting.
In addition to monthly disinfection reporting, this water system must submit the monthly average of chlorine residual samples taken in the distribution system. Distribution system chlorine
residual monitoring results are due quarterly by the same compliance dates as the monthly disinfection report and can be submitted via an online form found at mrdl.utah.gov.
Records must be maintained for a minimum of 5 years. [R309-105-17(1)]
Source Bacteriological Monitoring 
The operating permit will include requirements for monthly Escherichia Coli (E. Coli) sampling at City Hall Well (WS004), prior to any treatment, for the months the well is in operation
or accessible for a minimum of two operating seasons. This monitoring is required to evaluate the quality of the water coming from City Hall Well (WS004) to determine whether primary
disinfection treatment is required or not. Additional monitoring and/or disinfection requirements may be assigned depending on the results of the assessment monitoring.
The source sampling requirement shall begin no later than March 2025 and extend to cover the duration of at least 18 months, sufficient to span two (spring/summer or peak season) cycles.

The sampling location of the source water bacteriological samples needs to be labeled as WS004. 
The source bacteriological sampling is in addition to the monthly total coliform sampling in the distribution system (DS001) that has been in place for your water system. 
The required source sampling data must be submitted to the Division for evaluation before a permanent operating permit can be issued for City Hall Chlorinator (TP002).
In the result of an E. coli positive sample, please contact Sitara Federico at [e-mail] or [phone] within 24 hours of notification.
