Dear Angie Taylor:The Division of Drinking Water (the Division) received the plans and specifications for drilling the Zion Red Rock Retreat Well from Richard Emerson, Cascade Water
Resources on June 5, 3024.
We understand that this project consists of drilling a new well for the Zion Red Rock Retreat. Two other wells currently exist but don’t meet the Division’s construction standards and
this well is intended to meet those standards and to be used to provide drinking water for the water system. The well will be drilled to a depth of approximately 217 feet with a minimum
10 3/4-inch diameter borehole. A 6-inch (ID) diameter production casing will be installed inside the borehole. Approximately 177 feet of steel casing and 40 feet of wire wrapped screen
(varying depths) will be placed from a minimum 18 inches above the ground surface to 217 feet deep. In the annular space between the 6-inch diameter casing and the borehole, from the
ground surface to a depth of 105 feet, the well will be grouted with approved grout. From the bottom of the drill hole to about 105 feet deep, the annular space will be filled with silica
sand filter pack. The Zion Red Rock Retreat Well is identified as WS003 in the Division’s database.
We have received the following information for the Zion Red Rock Retreat Well:
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 Richard Emerson, P.G., and dated June 5, 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 the Zion Red Rock Retreat Well are hereby approved. This approval pertains
to well drilling, development, aquifer testing, and disinfection of Zion Red Rock Retreat Well 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 Zion Red Rock Retreat Well 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 UTAH27115 and WS003 (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.
Preliminary Evaluation Report Concurrence
The Division has also reviewed the Preliminary Evaluation Report (PER) for this source submitted by your consultant on June 5, 2024. The Division requested revisions to the PER on June
12, 2024, and your consultant responded the same day. The Division concurs with this report. This report must be refined, and a complete Drinking Water Source Protection (DWSP) plan
submitted within one year of the date of this letter. Refer to R309-600-13(6) and R309-600-7(1). You must submit proof that a map of the zones has been provided to Washington County
to be covered under the Washington County Source Protection ordinance before the well can receive an Operating Permit. If you have questions about the source protection requirements,
please contact Deidre Beck at [phone] or via email at [e-mail].
If you have any questions regarding this approval, please contact J. Paul Wright, P.E., DEQ Southwest District Office, at [phone], or me at (385) 515‑1464.
Sincerely,
Michael Newberry, P.E.
