Dear Chris Haramoto:The Division of Drinking Water (the Division) received the plans and specifications for the proposed well equipping of the Lost Creek Well 2 (WS002) and Lost Creek
Well 2 RO (TP001) from your consultant, Ryan Devitt, PE with Civil Science on August 22, 2024. The Division requested clarification on the various projects on August 27, 2024, and received
additional information on October 8, 2024. The Division issued an ATF Plan Approval for drilling Lost Creek Well 2 on December 11, 2023. Plan review comments were sent on October 22,
2024. Revised plans were received on November 11, 2024.
Our understanding of the project is the equipping of the Lost Creek Well 2 including the installation of a pre-treatment filter, water softener, reverse osmosis plant, and installation
of a chlorination system.
Well Equipping
This portion of the project includes the construction of the well house and installation of a 2 HP Grundfos with Franklin Electric Motor submersible pump with a pump rate of 10 gallons
per minute (gpm) at 165 feet of head. A pitless adapter will be installed on the well head. This well is identified as WS002 in the Division’s database.
Pre-Treatment Filtration and Reverse Osmosis Treatment Plant
Due to high turbidity of the raw water, a Culligan 20-inch OFSY Omni-Filtration system will be installed prior to any other treatment. A Culligan CTM-300-PF softener system will be installed
along with a Culligan G2-7HE Reverse Osmosis (RO) System. The RO system consists of two parallel units for full redundancy with a flow rate of 9.2 gpm for each unit. The RO plan will
treat elevated turbidity, iron, and toluene in the source water. Waste from the RO plant will be discharged to evaporation basins. Detailed project description and the Division’s decision
to issue Plan Approval for the Lost Creek Well 2 RO treatment plant are summarized in the Project Overview Addendum. This RO treatment plan is identified as TP001 in the Division’s database.
Chlorinator
The plan review of the proposed chlorinator has been completed according to the following:
The proposed Lost Creek Well 2 Chlorinator is a liquid chlorinator, adding sodium hypochlorite solution of 5.25% concentration.
This chlorinator will add chlorine to the water from Lost Creek Well 2 (WS002).
This chlorinator is intended for disinfection on an elective basis. 
Where the chlorinated water will go, e.g., to the 143K Gallon Tank (ST001).
The proposed sodium hypochlorite for disinfection meets the ANSI/NSF 60 standard.
The proposed design target dose of 0.5 mg/L or ppm (measured as free chlorine) is based on a typical flow of 10 gallons per minute (gpm) from Lost Creek Well 2.
The chlorine dose will be adjusted by an automatic flow-paced control using a Grundfos DDA dosing pump and flow meter.
The Point of Entry (POE) sampling location will be located at the well house after chlorination.
We have received the following information for Well Equipping, Lost Creek Well 2 (WS002), Lost Creek Well 2 RO (TP001):
New Source Chemical Analysis of the well water.
Plans and specifications for equipping the well.
Pump information.
Well head discharge piping.
Well house design and pitless adapter.
Chlorinator design.
Reverse Osmosis design.
We have completed our review of the plans and specifications, stamped, and signed by Cody Howick, P. E., and dated August 14, 2022, 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 Equipping, Lost Creek Well 2 (WS002), Lost Creek Well 2
RO (TP001)are hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before Well Equipping, Lost Creek Well 2 (WS002), Lost Creek Well 2 RO (TP001) 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.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.
Source Monitoring
The initial new source chemistry data of the well water indicated turbidity, chloride, aluminum, and iron above their respective maximum contaminant levels (MCLs) and maximum contaminant
level goals (MCLGs). It is the Division's understanding that the addition of a Reserve Osmosis and softening system will reduce these contaminant concentrations to below their applicable
limits. Pursuant to R309-215-6(2)(a) and R309-205-5, the water system will be required to sample the Lost Creek Well 2 (WS002) after it has undergone treatment at the Lost Creek Well
2 RO (TP001) for turbidity, chloride, aluminum, iron, nitrate, and sulfate on a routine basis at varying frequencies upon the issuance of an operating permit. Please contact David Kruse
at [e-mail] or (385) 5667789 for questions regarding the source monitoring requirements for this water system.
Prior to the issuance of an operating permit, to demonstrate treatment efficacy please submit two sets of pre and post treatment sample results from the raw and treated water for sodium,
turbidity, chloride, aluminum, iron. Sample sets should be collected 24 hours apart.
If you have any questions regarding this approval, please contact Cameron Draney, P.E., of this office, at [phone], or me at [phone].
Sincerely,
Michael Newberry, P.E.

Lost Creek State Park Water System (UTAH15045)
Lost Creek Well 2 RO Water Treatment Plant (TP001)
Our understanding of the project is that the proposed Lost Creek Well 2 RO treatment plant will treat water from the Lost Creek Well 2 (WS002).
The New Source Chemical Analysis indicated levels of turbidity and iron above the MCL as well as other contaminants such as toluene.The proposed Lost Creek Well 2 RO water treatment
plant consists of pre-filter, water softening, reverse osmosis, and post-chlorination processes. The proposed Lost Creek Well 2 RO (TP001) has a plant design capacity of 9.2 gallons
per minute (gpm). The design includes 2 train(s) of all processes, and each train of 9.2 gpm.The proposed treatment plant consists of the following processes in sequence:One-stage pre-filter
– Culligan 20-inch OFSY Omni-Filtration; 2 trains (1 for full redundancy); 20 gpm per train.
Ion Exchange Water softener - Culligan CTM-300-PF; 2 trains (1 for full redundancy); 75 gpm per train.
Reverse Osmosis System - Culligan G2-7HE Reverse Osmosis; 2 trains (1 for full redundancy); 9.2 gpm per train.Post-chlorination – sodium hypochlorite injection; dosing at 0.5 mg/l to10
gpm per train.
