Dear Craig Christoffersen:The Division of Drinking Water (the Division) received the plans and specifications for the Hammons Well Drilling and a Preliminary Evaluation Report (PER)
from your consultant, Matthew Hartvigsen, P.E. on November 27, 2024. Division staff requested additional source protection information on December 11, 2024, and your consultant provided
revisions to the PER on January 20, 2025.We understand that this project consists of drilling an 18-inch diameter borehole to a depth of 800 feet to accommodate a 12-inch diameter well
casing. A 20-inch diameter surface conductor casing will be installed to a depth of 100 feet with the annular space between the surface conductor casing and well casing being filled
with neat cement. A sanitary seal of neat cement will be installed outside of the surface conductor casing to a minimum depth of 100 feet. Beyond the sanitary seal, a bentonite clay
seal will be installed with a gravel pack being installed for the remainder of depth. A 2.5-inch diameter gravel feed pipe will be installed for gravel pack replenishment. It is anticipated
to install three sections of stainless-steel wire wrap screens of 100 feet each for a total of 300 feet of screens. The Hammons Well is identified as WS011 in the Division’s database.
We have received the following information for Hammons Well Drilling:
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 Mathew Hartvigsen, P.E., and dated October 25, 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 Hammons Well are hereby approved. This approval pertains to well drilling,
development, aquifer testing, and disinfection of Hammons 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 Hammons 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 UTAH02014 and WS011 (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 the Preliminary Evaluation Report (PER) from your consultant, Matthew Hartvigsen, P.E., on November 27, 2024. Division staff requested additional information on
December 11, 2024, and your consultant provided revisions to the PER on January 20, 2025.
We have completed our review of the PER, stamped, and signed by Jason C. Biesinger, P.E., with Hanen Allen & Luce, Inc., and dated December 16, 2024, and found it basically complies
with the applicable portions of Utah’s Administrative Rules for Public Drinking Water Systems. 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 Box Elder County for the source to be covered under the Box Elder County drinking water 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 Cameron Draney, P.E., of this office, at [phone], or me at [phone].
Sincerely,
Michael Newberry, P.E.
