Dear Rodney Wheeler:The Division of Drinking Water (the Division) received the plans and specifications for the Stockton Old Tank Well from your consultant, Christopher DeKorver, and
Bowen Collins & Associates on July 23, 2024. Review comments were sent to your consultant, and return comments were received on August 26, 2024.We understand that this project consists
of the drilling and installation of a 20-inch diametersurface casing to an approximate depth of 100 feet, the casing to be approximately 250 feet of12-inch diameter steel blank casing,
and 850 feet of 12-inch diameter wire wrap SS 304 screen;installation of certified cement grout of the 12-inch surface casing to approximately 100 feet;installation of gravel pack and
certified cement grout well seal of the 12-inch diameterproduction casing and screen assembly; and development and test pumping of the proposed Old Tank Well (identified as WS010 in
the Division’s database).
We have received the following information for Old Tank 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 Christopher DeKorver P.G. and dated July 23, 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 Old Tank Wellare hereby approved on the following condition:
A valid Start Card from the Division of Water Rights must be submitted to the Division of Drinking Water prior to the start of drilling.
This approval pertains to well drilling, development, aquifer testing, and disinfection of Old Tank 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 Old Tank 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 UTAH23010 and WS010 (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 received a Preliminary Evaluation Report (PER) from your consultant, Christopher DeKorver, P.G., with Bowen Collins & Associates, Inc., on July 23, 2024. The Division requested
additional information via email on July 25, 2024. Your consultant provided revisions to the PER on August 19, 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). You must submit proof that
a map of the zones has been provided to Tooele County for the source to be covered under the Tooele County source protection ordinance before the well can receive an Operating Permit.
Please contact Deidre Beck, P.G., at [phone] or via email at [e-mail] if you have questions about these requirements.
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.
