of Utah’s Administrative Rules for Public Drinking Water Systems in R309. On this basis, the plans for the Hildale Water Line Extension, Innovation Center Project are hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before this 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.
