Subject:After the Fact Plan Approval andOperating Permit, Country Club Drive Well Chlorinator (TP003); Bear Lake Water Company, System #17010,File #16706
Dear Douglas Pincock:
During the 2024 Sanitary Survey of your water system, it was discovered that the new Country Club Drive Well (WS006) also had a chlorinator. Upon review of the submitted plans for well
equipping, the Division of Drinking Water (the Division) found the chlorinator was included. The Country Club Drive Well (WS006) was permitted and issued an operating permit on May 2,
2022 under Plan Review File #11246. After review of the equipping plans, this project has met all conditions for receiving an after the fact plan approval and operating permit.
Our understanding of the project is that as part of the Country Club Drive Well (WS006) project, a liquid hypochlorite chlorinator was also installed. The Country Club Drive Well Chlorinator
(TP003)included in this project has been completed according to the following:
The Country Club Drive Well Chlorinator adds liquid sodium hypochlorite solution to provide secondary disinfection.
The Country Club Drive Well Chlorinatortreats water from the Country Club Drive Well (WS006). The sodium hypochlorite is added to the water in the well house after the flow meter for
the well.
The chlorinated water then enters Storage Facility ST001 (ST001) and flows into the distribution system.
The liquid sodium hypochlorite used for disinfection meets the ANSI/NSF 60 standard.
A design target dose of 0.5 to 1.0 mg/L (ppm) of free chlorine is based on a typical flow of 700gallons per minute (gpm) from the Country Club Drive Well (WS006).
The chlorine dose is adjusted manually on the chlorine pump based on the residuals seen in the distribution system.
We have received the following information for the Country Club Drive Well Chlorinator (TP003)as part of the previous project for the Country Club Drive Well (WS006):
Certification of Rule Conformance with plan approval conditions by a professional engineer
As Built Plans.
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 After the Fact Plan Approval and Operating Permit for the Country Club Drive Well
Chlorinator (TP003)is hereby issued as constituted by this letter.
Please maintain a copy of this letter with your permanent records for future reference.
Secondary Disinfection Requirements
The Bear Lake Water Companyis not required to disinfect the Country Club Drive Well (WS006)based on bacteriological source sample results currently available. The water systemhas voluntarily
installed the Country Club Drive Well Chlorinator (TP003) to provide a detectable disinfectant residual in the distribution system for secondary disinfection.
Please be aware that, if any water source of the Bear Lake Water Companyis found to require primary disinfection in the future per R309-200-5(7)(a)(i), additional regulations will apply.
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 Bear Lake Water Companyis required to demonstrate ongoing compliance with the secondary disinfection requirements outlined in Addendum 1 of this letter as long as the Country Club
Drive Well Chlorinator (TP003)is in operation.
Monitoring and ReportingIssuance of this Operating Permit changes your water system’s monitoring and reporting requirements, as in Addendum 1.Please contact Mark Berger, Water Quality/Monitoring
and Standards Manager at [phone] for questions regarding the monitoring and reporting requirements for your water system.
There may be new changes in monitoring and reporting requirements in the future as the Division continues to improve the disinfection monitoring and reporting practices. Failure to adhere
to required monitoring and reporting will result in violations and the assessment of IPS points.
If you have any questions regarding this Operating Permit, please contact Dani Zebelean, P.E., of this office, at [phone], or Michael Newberry, P.E., Permitting and Engineering
Support Manager, at [phone].
Sincerely,
Russell Seeley, P.E.

Addendum 1 
Elective Monitoring and Reporting Requirements 
Chlorine Monitoring & Reporting Requirements
The water system is required to meet elective disinfection requirements. As a part of these requirements, the water system is required 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 is identified asEP003in the Division’s database. This location has been identified as the fire hydrant that is readily available to take samples from, after
the well house. 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 once per day. [R309-210- 8(3)(a)(ii)]

Our records show that your water system serves 1,200 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 [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 
This water system is required to take monthly bacteriological samples of the Country Club Drive Well (WS006) prior to any treatment, for the months the well is (in operation or accessible).
The source sampling requirement shall begin in November 2024 and continue for a minimum of 12 months.
The purpose of the source sampling requirement is to gather data to evaluate the quality of the source water from Country Club Drive Well (WS006) and determine whether primary disinfection
treatment is required or not.
Label the source samples with WS006 as the sampling location. 
The required source bacteriological sampling is shown on your monitoring schedule for this sample site. Please note that the source sampling is in addition to the distribution system
bacteriological sampling already in place, which is labeled DS001.
After 12 months of source sampling data becomes available, the Division will evaluate the results to determine whether primary disinfection is required for Country Club Drive Well (WS006).
Please contact Sitara Federico for any positive samples that may occur at the source at 385-515-1459 or [e-mail]. If any sample result comes back as E. coli positive, please
contact the Division within 24 hours of being notified of the result.
