Dear Keith Mogan:The Division of Drinking Water (the Division) received the plans and specifications for the proposed Richfield City Culinary Water Distribution System Improvements Project
from your consultant, Parker Vercimak, with Jones & DeMille Engineering on April 26, 2024. This project has met the conditions for receiving a plan approval.
Our understanding of the project is that existing, undersized distribution pipelines are being replaced in various parts of the city. Approximately 3,700 feet of new 8-inch diameter
PVC piping will be installed, along with new isolation gate valves, fire hydrants, and service connections. It is our understanding that these pipelines are being replaced with the diameter
of pipes recommended in the City’s most recent computer hydraulic analysis of the system.
We have completed our review of the plans and specifications, stamped, and signed by Parker Cade Vercimak, P.E., dated March 27, 2024, 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 the Richfield City Culinary Water Distribution System Improvements Project
are hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before the new water lines 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 John Chartier, DEQ Central District Engineer, at [phone], or me at [phone].
Sincerely,
Michael Newberry, P.E.
