Subject:Plan Approval, Pony Express Parallel 16 inch Diameter Water Line (DS001);
Eagle Mountain City, System #25142, File #20534
Dear Mack Straw:The Division of Drinking Water (the Division) received the plans and specifications for the proposed Pony Express Parallel 16-inch Diameter Water Line Project from Vince
Hogge on April 2, 2025. This project has met the conditions for receiving a plan approval.
Our understanding of the project is the installation of approximately 4,686 feet of 16-inch diameter ductile iron pipe (DIP), beginning on the Pony Express Parkway from the existing
Unity Pass Booster Station (PF005) tying into the existing 16-inch diameter water line on Lake Mountain Road. This proposed water line will increase the capacity of water to Tank 1 (ST001)
and Tank 7 (ST007).
We have completed our review of the plans and specifications, stamped and signed by Sheila Young, P.E., dated March 27, 2025,and find they basically comply with the applicable portions
of Utah’s Administrative Rules for Public Drinking Water Systems in R309. On this basis, the plans for Pony Express Parallel 16” Waterlineare hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before Pony Express Parallel 16-inch Diameter Water Line may be put in service. A
checklist outlining the items required for operating permit issuance is enclosed for your information.
Approvals or permits from the local authority or the 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 equipment has not been ordered within one year of the date of this letter.
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.
