Lindon City, System #25016, File #15782
Dear Matthew Winward:The Division of Drinking Water (the Division) received the plans and specifications for the proposed drilling of Well #5 120 E 600 N (WS006) from your consultant,
Lance Nielsen and Hansen, Allen & Luce on July 18, 2024. Written review comments and requested revisions to the PER were sent to your consultant on July 30, 2024. The revised PER was
received on October 7, 2024. The Division of Water Rights Start Card was received on October 8, 2024.
We understand that this project consists of the drilling of a pilot hole followed by the drilling for a 20-inch diameter casing production well using the flooded reverse rotary drilling
method. The anticipated depth of the well is to be approximately 1,000 feet below ground surface (bgs). The well is to be used in the Lindon City drinking water system. The Well #5 120
E 600 Nis identified as WS006in the Division’s database.
We have received the following information forWell #5 120 E 600:
Plans and specifications for borehole and well drilling.
Preliminary Evaluation Report
Valid Start Card (or authorization to drill letter) from the Division of Water Rights
We have completed our review of the plans and specifications, stamped, and signed by Scott Greenhalgh, P.G., and dated July 17, 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 #5 120 E 600are hereby approved. This approval pertains to well

drilling, development, aquifer testing, and disinfection of Well #5 120 E 600 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 #5 120 E 600 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 UTAH25016 and WS006 (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 July 17, 2024. The Division requested revisions to the PER on July
30, 2024, and your consultant provided revisions on October 7, 2024. 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).
Please contact Noah Zorsky, 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 Brent Arns, of this office, at [phone], or me at [phone].
Sincerely,
Michael Newberry, P.E.
