Dear Scott Taylor:
The Division of Drinking Water (the Division) received the plans and specifications for the proposed Industrial Tank Project from Glen Carnahan, P.E., Alpha Engineering, on March 12,
2025. A request for clarification on one item in the plans was sent to you and your consultant on April 7, 2025. A response with plan revisions was received by the Division on April
8, 2025. This project has met the conditions for receiving a plan approval.
Our understanding of the project is to construct a 2 MG reinforced concrete tank that will be named Industrial Tank (identified as ST021 in the Division’s inventory database). This
tank will replace the existing North Industrial Park Tank (ST016) and will be constructed adjacent to it. Construction includes all associated appurtenances including a hatch, air vent,
and overflow/drain line. The tank also includes the installation of new ductile iron pipe to be used as inlet and outlet water lines for the tank that will connect to the distribution
system.
We have completed our review of the plans and specifications, stamped and signed byGlen E. Carnahan, P.E., dated March 7, 2025, and found 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 Industrial Tank (ST021) are hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before Industrial Tank 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 J. Paul Wright, P.E., DEQ Southwest District Office, at [phone], or me at [phone].
Sincerely,
Michael Newberry, P.E.
