Gardner Pine Valley Irrigation Co. 1766 Winchester Drive St. George, Utah 84770 Subject:Plan Approval, Well Drilling, Well 2 (WS005); Pine Valley Irrigation Co., System #27025, File #11989 Dear Ryon Gardner:The Division of Drinking Water (the Division) received the plans and specifications for the Pine Valley Irrigation Company Well 2 from Todd Gardner, P.E. Alpha Engineering on January 24, 2020. At that time, the PER was not able to be concurred with because of septic systems located within Zone 2. A new PER was submitted in November of 2023 with a new well location. Revised plans and specifications for drilling the well, based on the new well location, were submitted on June 25, 2024. We understand that this project consists of a drilling minimum 24-inch diameter surface borehole to a depth of 100 feet. A 20-inch diameter permanent conductor casing will also be installed to a depth of 100 feet. The well will be grouted between the borehole and surface casing to a depth of 100 feet. Well 2 will be drilled to a depth of approximately 600 feet with an 18-inch diameter well borehole and a 12-inch diameter production steel casing, 120 feet long, andstainless steel screens at various depths totaling another 480 feet.The surface casing (20-inch) and the blank steel casings (12-inch) will be ASTM A53 Grade B black steel with 0.250-inch thickness. Gravel will be placed between the permanent production casing and the borehole from 100 feet below Ground Surface (BGS) to 600 BGS and between the permanent conductor casing and the production casing from the ground surface to 100 ft BGS. A steel ring will be welded at the top of the casing between the 20-inch surface casing and the 12-inch production casing to seal the inner annular space where the gravel pack will be installed.A 2-inch telemetry tube will be installed in the gravel pack from the surface to the bottom of the well. There will also be a 6-inch gravel refill port welded at the surface of the annular ring and will be capped. The project also includes well development, logging, and pump tests. The Well 2 is identified as WS005 in the Division’s database. We have received the following information for the Pine Valley Irrigation Company Well 2 drilling project: Plans and specifications for borehole and well drilling. Preliminary Evaluation Report . We have completed our review of the plans and specifications, stamped, and signed by Todd Brent Gardner, P.E., and dated July 1, 2024, and found they basically comply with the applicable portions of Utah’s Administrative Rules for Public Drinking Water Systems. On this basis, the plans for drilling Well 2 are hereby approved. This approval pertains to well drilling, development, aquifer testing, and disinfection of Well 2 only. Please be aware that discharge permits may be required by Utah Division of Water Quality for discharges generated during well drilling and aquifer drawdown testing. The Utah Division of Water Rights (State Engineer’s Office) regulates the drilling of water wells. Before the drilling of a well commences, the well driller must receive a start card from the State Engineer’s Office. Please be aware that, for public drinking water supply wells, in addition to the Division of Drinking Water’s R309-515 rule, the Division of Water Rights’ rule R655-4 also applies and shall be followed. After drilling is completed, you are required to submit additional information outlined in R309-515-6(5)(b) and (c) for review andobtain an approval from the Director for equipping this well and constructing discharge piping and infrastructure necessary for introducing the well water into the distribution system. After obtaining the well equipping approval, you’ll then be required to obtain an Operating Permit before Well 2 may be put in service. A checklist outlining the well approval process, including the items required for well equipping and an Operating Permit, is enclosed for your information. Please label the well water sample collected for new source chemical analysis with your water system number UTAH27025 and WS005 (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. 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 materials have not been ordered within one year of the date of this letter. Concurrence – Preliminary Evaluation Report The Division received the Preliminary Evaluation Report (PER) for the Pine Valley Irrigation Co Well 2 from your consultant, Brent Gardner, PE and Alpha Engineering on November 29, 2023 with subsequent information requested and received on April 24, 2024, June 3, 2024 and June 24, 2024. The Division concurs with this report. This PER must be refined, and a complete Drinking Water Source Protection (DWSP) Plan is submitted within one (1) year of the date of this letter. Refer to R309-600-13(6) and R309-600-7(1). You must submit proof that the delineation has been submitted to Washington County to be covered under the Washington County Drinking Water Source Protection Ordinance before the well can receive an operating permit. Please contact Melissa Noble, P.G., at (385) 271-7043 or at mnoble@utah.gov if you have questions or concerns about the review of your Preliminary Evaluation Report. If you have any questions regarding this approval, please contact J. Paul Wright, P.E., DEQ Southwest District office, at (435) 986-2590, or me at (385) 515‑1464. Sincerely, Michael Newberry, P.E.
