Subject:Operating Permit, Camp Kolob Deer Haven Chlorinator (TP001);
Camp Kolob - Deer Haven Ranch, System #27042, File #13256
Dear Andrew Clark Beecher:
The Division of Drinking Water (the Division) received a request for an Operating Permit for the Camp Kolob - Deer Haven Chlorination Project from Jon Oldham, Bowen Collins & Associates
on November 1, 2024. Previously, the Division received the plans and specifications for the Camp Kolob - Deer Haven Chlorination Project on February 15, 2024. Written review comments
were provided to you and your consultant on March 6, 2024. The Division received a response to the comments on March 6, 2024. Plan approval was issued on April 3, 2024. This project
has met all conditions for receiving an operating permit.
Our understanding of the project was to install a chlorinator that meets the secondary disinfection requirements outlined in a letter dated February 7, 2023, sent to the Camp Kolob -
Deer Haven Ranch water system. The project includes a new building to house the chlorinator.
The Camp Kolob Deer Haven Chlorinator (TP001) included in this project has been completed according to the following
The Camp Kolob Deer Haven Chlorinator adds a sodium hypochlorite solution of 5.25% concentration; the pump is a Blue-White Flexflow M14-4T peristaltic type.
This chlorinator adds chlorine to the water from Upper Spring (WS001).
This chlorinator will provide secondary disinfection in the distribution system.
The chlorinated water is conveyed to the dual 20,000-gallon tanks (Deer Haven Tank #1 (East) - ST001 and Deer Haven Tank #2 (West) - ST002) then to the distribution system.
The sodium hypochlorite for disinfection meets the ANSI/NSF 60 standard.
The design target dose of 1.0 mg/L or ppm (measured as free chlorine) is based on a typical flow of 2 to 10 gallons per minute (gpm) from Upper Spring (WS001).
The chlorine dose is adjusted by an automatic flow-paced control based on a flow meter for Upper Spring (WS001).
The Point of Entry (POE) sampling location is a HACH CL17sc continuous analyzer located at the Central Restroom building.
We have received the following information for Camp Kolob Deer Haven Chlorinator (TP001):
Certification of Rule Conformance with plan approval conditions by a professional engineer.
As-built or record drawings.
Satisfactory bacteriological results as evidence of proper disinfection and flushing.
Evidence of operation and maintenance manual delivery.
We have determined that all conditions for issuing an operating permit have been met. On this basis, an Operating Permit for the Camp Kolob Deer Haven Chlorinator (TP001)is hereby issued
as constituted by this letter. You may now place the Camp Kolob Deer Haven Chlorinator (TP001) in service in your water system.
Please maintain a copy of this letter with your permanent records for future reference.
Secondary Disinfection Requirements
The Division has determined that theCamp Kolob - Deer Haven Ranchmust provide continuous disinfection to maintain detectable chlorine residuals throughout the distribution system. The
Camp Kolob Deer Haven Chlorinator (TP001)is intended to provide a detectable disinfectant residual in the distribution system for secondary disinfection.
The Camp Kolob Deer Haven Chlorinator (TP001) is based on providing secondary disinfection. When this chlorinator is installed and placed in operation after the Operating Permit issuance,
the Camp Kolob - Deer Haven Ranch will be required to demonstrate ongoing compliance with the secondary disinfection requirements that will be outlined in Addendum 1 to this letter.
The Division shall be informed by telephone within 8 hours by a water supplier ofthe malfunction of any disinfection facility such that a detectable residual cannot be maintained at
all points in the distribution system per R309-105-18(1)(a).
Please be aware if Upper Spring (WS001) is found to requireadditionaldisinfection in the future per R309-200-5(7)(a)(i), further regulations will apply. For example, if primary disinfection
is required this will include submitting disinfection CT information showing compliance with 4-log virus inactivation in accordance with the Ground Water Rule in R309-215-16.The issuance
of this Operating Permit resolves your water system’s deficiency S001 related to previously not having the chlorinator installed. An updated IPS report isavailable at https://waterlink.utah.gov.
Please contact Jennifer Yee at (385) 515-1501 or jyee@utah.gov for questions related to your water system’s IPS report or deficiencies.
If you have any questions regarding this Operating Permit, please contact J. Paul Wright, DEQ Southwest District Engineer, at (435) 986-2590, or Michael Newberry, Permitting and Engineering
Support Manager, at (385) 515-1464.
Sincerely,
Russell Seeley, P.E.

Addendum 1
Secondary Monitoring and Reporting Requirements
Chlorine Monitoring & Reporting Requirements
The Camp Kolob - Deer Haven Ranch water system will be required to meet secondarydisinfection 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. Camp Kolob - Deer Haven will be required to demonstrate ongoing compliance with the followingsecondary disinfection requirements:
Secondary Disinfection Requirements and Reporting
Chlorine Residual ‒ Point of Entry (POE) to Distribution System
The POE sampling location will be identified as EP001 in the Division’s database. The location will be the continuous chlorine analyzer. 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 chlorine residual concentration, measured as free chlorine, at the chlorinator POE sampling location a minimum of daily [R309-210- 8(3)(a)(ii)]
Our records show that your water system serves 170 people. Please be aware that R309-215-16(3)(b)(iii)(A)(II) requires water systems serving 3,300 people or fewer to monitor the POE
chlorine residuals and take daily grab sample(s). Alternatively, instead of taking daily grab samples, a groundwater system serving 3,300 or fewer people may choose to use an online
analyzer to continuously monitor the POE chlorine residuals entering the distribution system.
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 secondary 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 (385) 258-6084 or ltreutel@utah.gov 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)]
