Tooele County General, System #23000, File #23075
Dear Rachelle Custer:The Division of Drinking Water (the Division) received the plans and specifications for the proposed Tooele County Ibapah Well from your consultant, Robert Rousselle
and Ensign Engineering and Land Surveying on June 27, 2025. Review comments were sent on July 14, 2025; revised plans were received on July 15, 2025.
We understand that this project consists of drilling a drinking water well on Tooele County property. The Tooele County Ibapah Well is proposed to be an 8-inch diameter casing to a depth
of approximately 450 feet below ground surface. It will be equipped with a submersible pump able to divert 45 gpm. The Tooele County Ibapah Wellis identified as WST002in the Division’s
database.
We have received the following information forTooele County Ibapah Well (WST002):
Plans and specifications for borehole and well drilling.
Preliminary Evaluation Report
Driller Start Card
We have completed our review of the plans and specifications, stamped and signed by Robert Rousselle, P.E., and dated June 28, 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 Tooele County Ibapah Well (WST002) are hereby approved. This approval pertains to well drilling, development, aquifer testing, and disinfection of Tooele County Ibapah
Well (WST002) 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 Tooele County Ibapah Well (WST002) 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 UTAH23000 and WST002 (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 Tooele County Ibapah Well from your consultant, Robert Rousselle and Ensign Engineering & Land Surveying on June
27, 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 proof that the delineation has been submitted to Tooele County to be covered under the Tooele County Drinking
Water Source Protection Ordinance 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 Chris Martin, P.E., of this office, at [phone], or me at [phone].
Sincerely,
Michael Newberry, P.E.
