The Division issued Plan Approval for drilling Well #1 on February 22, 2023. Note that this well was granted a Plan Approval for drilling and was drilled under the ownership of Eden Crossing, UTAH29132 (file #13247, WS003). Both systems have since confirmed the ownership of this well has been transferred to Nordic Village Water District and will be equipped and operated under the new system. Our understanding of the project is the equipping of the well with a XYLEM DWT 10WAHC 130 hp 350 gpm vertical turbine pump that will supply water to the proposed 700,000-gallon Nordic Valley Water Tank via the proposed 4,700 feet of 8-inch ductile iron pipe (DIP) and 4,760 feet of 12-inch diameter C-900 PVC pipe. Other improvements include PRV’s, air vac valves, fire hydrants, and other appurtenances. We have received the following information for Well 1 Equipping, Nordic Village Water Tank, and Distribution 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. XYLEM DWT 10WAHC 130 hp 350 gpm with a TDH of 1,020 ft Well head discharge piping. Well house design. Plans and specifications for storage tank. Plans and specifications for distribution line. We have completed our review of the plans and specifications, stamped, and signed by Byron Colton, P. E., and dated March 31, 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 equipping WELL 1, Nordic Village Water Tank, and Distribution Lineare hereby approved. This approval pertains to construction only. An Operating Permit must be obtained from the Director before Well 1, Nordic Village Water Tank, and Distribution Line 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. Source Protection Requirements The Drinking Water Source Protection (DWSP) plan was submitted to the Division by Eden Crossing called Well #3 (29132 WS003) on November 6, 2023. The Division concurred with the DWSP plan on March 7, 2024. The Updated DWSP plan is due December 31, 2028. Please reach out to source protection staff if you do not have the DWSP plan and concurrence letter referenced above, and if you have any questions about the source protection requirements. New Source Chemical Analysis The initial new source chemistry data of the well water indicated turbidity at levels above 5 NTU. Before an Operating Permit can be issued for this source, the system must re-sample for turbidity and submit the results to the Division as a proof of meeting the MCL for turbidity. Additionally, the new source chemistry analysis detected toluene at levels of 1.2 ug/L. Although this is below the maximum contaminant level, this result triggers increased monitoring requirements pursuant to R309-205-6(2). Upon the issuance of an operating permit this source will be required to be sampled quarterly for Volatile Organic Compounds (VOCs). Iron was detected in the analysis at levels of 0.37 mg/L. This is above the secondary maximum contaminant level of 0.3 mg/L. Sources containing levels of iron above secondary standards are likely to cause customer complaints. Please contact David Kruse at (385) 566 7780 or dbkruse@utah.gov with any questions regarding the source monitoring requirements for this system. If you have any questions regarding this approval, please contact Cameron Draney, P.E., of this office, at (385) 271-7039, or me at (385) 515-1464. Sincerely, Michael Newberry, P.E.
