Subject:Plan Approval, Well Drilling, Rainbow Cove Well (WST01);
Rich County General, System #17000, File #22151
Dear Teri Eynon:The Division of Drinking Water (the Division) received the plans and specifications for the proposed Rainbow Cove Well from your consultant Richard Emerson, P.G., of
Cascade Water Resources on June 3, 2025. The preliminary evaluation report was concurred with on June 23, 2025. This project has met the requirements for a well drilling plan approval.
We understand that this project consists of drilling a new well for a proposed Rainbow Cove Public Culinary water system which is not yet assigned a public water system ID. The
The well will be drilled to approximately 300 feet-deep below ground surface (bgs). The water level is anticipated to be at 45 feet bgs. The well will have a 12-inch diameter borehole
to 300 feet (bgs) that will be sealed to 110 feet (bgs) for the sanitary seal. The drilling includes well development, step-rate, and constant-rate tests. The Rainbow Cove Well is identified
as WST01 in the Division’s database.
We have received the following information for the Rainbow Cove Well (WST01):
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., P.E., and dated June 3, 2025,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 Rainbow Cove Well are hereby approved. This approval pertains to
well drilling, development, aquifer testing, and disinfection of the Rainbow Cove 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 the Rainbow Cove 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 collected well water sample for new source chemical analysis with your water system number UTAH17000 and WST01 (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 Cove Well from your consultant, Richard Emerson and Cascade Water Resources on June 3, 2025. 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 copies of Land Use Agreements that have been recorded with Rich County before the well can receive an operating permit
Please contact Melissa Noble, P.G., at [phone] or at [e-mail] if you have questions or concerns about the review of your Preliminary Evaluation Report.
If you have any questions regarding this approval, please contact Dani Zebelean, P.E., of this office, at [phone], or me at [phone].
Sincerely,
Michael Newberry, P.E.
