Dear Amanda Buhler:The Division of Drinking Water (the Division) received the plans and specifications for drilling the Johnson Canyon Well #4 from Glen Carnahan, Alpha Engineering,
on June 10, 2024. Review comments on the well drilling were sent to you and your consultant on July 11, 2024. The Division received revised drilling plans on July 30, 2024.
We understand that this project consists of drilling a minimum 26-inch diameter surface borehole to a depth of 100 feet. A 22-inch diameter permanent conductor casing will also be installed
to a depth of 100 feet. The well will be grouted between the borehole and surface casing to a depth of 100 feet. Johnson Canyon Well #4 l will be drilled to a total depth of approximately
600 feet with a 20-inch diameter well borehole and a 12-inch diameter production casing consisting of about 22 ½ feet of steel casing from 2 ½ feet above the ground surface to 20 feet
below the ground surface (BGS). The rest of the production casing will be 12-inch PVC SDR 17 (ASTM 480-14) well casing and 12-inch PVC SDR 17 (ASTM 480-14) 0.06” slotted well screen
to a depth of 600 feet. Gravel will be placed between the 12-inch permanent production casing and the borehole from 100 feet to 600 feet BGS and between the permanent conductor casing
and the production casing from the ground surface to 100 feet BGS. A steel ring will be welded at the top of the casing between the 22-inch surface casing and the 12-inch production
casing to seal the inner annular space where the gravel pack will be installed. A 2-inch telemetry tube will be installed in the gravel pack from the surface to the bottom of the well.
There will also be a 6-inch gravel refill port welded at the surface of the annular ring and will be capped. The project also includes well development, logging, and pump tests. The
Johnson Canyon Well #4 is identified as WS006 in the Division’s database.
We have received the following information for the Johnson Canyon Well #4 drilling project:
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 Glen E. Carnahan P.E., and dated July 30, 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 Johnson Canyon Well #4 are hereby approved. This approval pertains
to well drilling, development, aquifer testing, and disinfection of Johnson Canyon Well #4 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 Johnson Canyon Well #4 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 UTAH13038 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.
Concurrence – Preliminary Evaluation Report
The Division received the Preliminary Evaluation Report (PER) for the Johnson Canyon Well #4 from your consultant on June 10, 2024. The Division requested additional information via
email on June 24, 2024. Your consultant provided revisions to the PER via email on August 6, 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 Kane County to be covered under the Kane 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, P.G., 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 [phone].
Sincerely,
Michael Newberry, P.E.
