Dear Robbie Mitchell:The Division of Drinking Water (the Division) received the plans and specifications for drilling the Mud Springs Well #1 from you on May 17, 2024.
We understand that this project includes drilling a 42-inch diameter borehole drilled to a depth of 40 feet with a 36-inch diameter surface casing. The annular space between the borehole
and casing will be grouted with sand cement grout. In addition, a 34-inch diameter borehole inside the 36-inch diameter casing will be drilled to a depth of 150 feet with a 26-inch
diameter surface casing installed. The annular space will also be filled with the same grout between the borehole and casing. The total depth of the hole will be drilled to about 1,200
feet. A 24-inch diameter borehole will be drilled inside the 26-inch diameter surface casing. A 16-inch diameter steel casing will be installed inside this borehole and will consist
of about 720 feet of 16-inch diameter casing and 480 feet of screens. Gravel pack will be installed between the 16-inch diameter casing and 24-inch diameter borehole to the surface.
An annular welded steel ring will be placed at the surface between the 16 and 26-inch diameter casings to seal the gravel pack. The project includes logging, water tests, step drawdown
and 24-hour constant rate pumping tests. The Mud Springs Well #1 is identified as WS019 in the Division of Drinking Water inventory.
We have received the following information for the Mud Springs Well #1 drilling project:
Plans and specifications for borehole and well drilling.
Preliminary Evaluation Report was concurred with in September 2023.
Driller start cards for the Utah Division of Water Rights.
We have completed our review of the plans and specifications, stamped and signed by Jonathan A. Stathis, P.E., and dated May 9, 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 Mud Springs Well #1 are hereby approved. This approval pertains to
well drilling, development, aquifer testing, and disinfection of the Mud Springs Well #1 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 Mud Springs Well #1 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 UTAH11002 and WS019 (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.
Drinking Water Source Protection Requirement
The Concurrence letter for the Preliminary Evaluation Report (PER) for the Mud Springs Well No. 1, Cedar City Waterworks was sent September 19, 2023. An updated due date for the refined
and completed Drinking Water Source Protection (DWSP) plan is to be 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 Cedar City to be covered under the Cedar City Source Protection ordinance before the well can receive an Operating Permit.
Please contact the Division at [phone] and ask for source protection staff if you have questions or concerns about the source protection requirements.
If you have any questions regarding this approval, please contact J. Paul Wright, P.E., DEQ Southwest District Office, at (4335) 986-2590, or me at [phone].
Sincerely,
Michael Newberry, P.E.
