Engineers on September 5, 2024.Our understanding of the project is the redevelopment of the north portion of the spring by replacing the collapsed section of pipe with new 10-inch diameter perforated PVC collection pipe, updating the collection boxes, and the installation of new collection area gravel to maximize the collection of spring water. The south portion of the spring was redeveloped in 2011. The spring name will remain as Wade Spring and is identified as WS002 in the Division’s database. We have received the following information forWade Springs Redevelopment Project: Plans and specifications for spring redevelopment. We have completed our review of the plans and specifications, stamped, and signed by Scott Royal Greenhalgh, P.G., and dated September 5, 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 redeveloping Wade Springs are hereby approved. Please label the spring water sample collected for new source chemical analysis with your water system number UTAH25022 and WS002 (for both the facility ID and sample point ID) on all laboratory forms for each individual source. This will ensure proper identification and entry of the new source chemical analysis results in our database. This approval pertains to construction only. Following completion of construction, you must obtain an Operating Permit prior to placing Wade Springsinto service. A checklist outlining the spring approval process, including the items required for issuing an Operating Permit is enclosed for your information. Enclosed please also find an Operating Permit Checklist for other components of this project.Please note that, before requesting an Operating Permit for this project, you must submit the required new source chemical analysis data to the Division for review to determine whether additional treatment is required for using the Wade Spring as a public drinking water source.The operating permit will include requirements for monthly Escherichia Coli (E. Coli) sampling at Wade Spring (WS002), also called assessment monitoring, during the operating period when the spring is accessible for a minimum of 6 months. This monitoring is required to evaluate the quality of the water coming from Wade Spring (WS002) to better protect public health. Additional monitoring and/or disinfection requirements may be assigned depending on the results of the assessment monitoring. 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. Drinking Water Source Protection Requirement A revised Drinking Water Source Protection (DWSP) plan is required within 180 days after the reconstruction or redevelopment of any ground-water source of drinking water (refer to R309-600-7(2)(f)). The revised plan must address changes in source construction, development, hydrogeology, delineation of the source protection zones, the potential contamination source inventory, etc., as applicable. An updated DWSP plan is currently pending review by Division staff but did not address the redevelopment. If redevelopment of the spring does not result in changes that would affect delineation of the source protection zones, please send an email to Deidre Beck, P.G., at dbeck@utah.gov indicating that no changes have occurred to the source protection zones due to the redevelopment. If you have any questions about the source protection requirements, please contact Deidre Beck, P.G., at (385) 271-7046 or via email at dbeck@utah.gov. If you have any questions regarding this approval, please contact Brent Arns, of this office, at (385) 549-7420, or me at (385) 515-1464. Sincerely, Michael Newberry, P.E.
