Subject:Plan Approval, Pine Valley Mt Farms Tank Floor Replacement and Refurbishment (ST001) and Water Line Replacement Project; Pine Valley Mt Farms, System #27061, File #13531, SRF
#3F1890
Dear Joni Flint:The Division of Drinking Water (the Division) originally received the plans and specifications for the Pine Valley Mt Farms Project from Jake Heward, Alpha Engineering,
on September 19, 2023. Written review comments were provided to you and your consultant on October 11, 2023. The project has since been modified and now only includes the water line
replacement and the tank replacement and refurbishment. The Division received the revisions and a response to the review comments from Colter Lund, Alpha Engineering on July 26, 2024.
This project has met the conditions for receiving a plan approval.
Our understanding is that this is a federally funded project as described below.
Water Line Replacement
This includes the replacement of 1,400 linear feet of existing 6-inch diameter water line along State Route 18 with 8-inch diameter PVC C900 pipe. An additional 900 linear feet of 8-inch
diameter PVC C900 will be installed to connect to and loop at the end of Pioneer Circle.
There is a bid alternate that consists of an additional 250 linear feet of 8-inch diameter PVC water line along State Route 18 to replace an existing 6-inch water line. This alternate
also provides for approximately 1,200 linear feet of 8-inch diameter water line along Wells Fargo Drive which terminates at the beginning of Pioneer Circle.
These water lines include all other appurtenant valves, fittings, and service connections along this part of the distribution system.
Tank Floor Replacement and Refurbishment
The existing 425,000-gallon tank will be taken offline. The floor will be replaced, a new manway will be constructed, and a new air vent installed on top of the tank. Once this is
complete, the interior of the tank will be sandblasted and recoated with approved ANSI/NSF 61 epoxy coating.
Temporary ANSI/NSF 61 approved drinking water storage tanks will be rented and temporary piping at the tank location will be installed to provide inlet and outlets for the water system.
These tanks will meet all the drinking water storage tank requirements to ensure that the water is safe for usage while the 425,000-gallon tank is out of service.
We have completed our review of the plans and specifications, stamped and signed Colter J. Lund, P.E., dated July 26, 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 Pine Valley Mt Farms Tank Floor Replacement and Refurbishment (ST001) and Water
Line Replacement Project are hereby approved.
Because this project includes tank recoating as part of the project, following are important items for the tank recoating:
Use ANSI/NSF 61 certified coating material.
Provide forced air ventilation for proper curing.
Make sure the ambient temperature and curing duration specified by the coating manufacturer are followed during the curing process.
After the coating is fully cured, do a thorough flushing. We require a clean VOC sample from the tank before an Operating Permit can be issued for the tank recoating project (as shown
in the OP checklist.).
This approval pertains to construction only. An Operating Permit must be obtained from the Director before the Tank (ST001) and 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.Federal SRF ProgramThe project,
as described herein, is generally eligible for assistance under the Drinking Water Construction Assistance Program. All change orders will need to be reviewed and approved for compliance
with the Drinking Water Rules and the conditions of this construction approval.The project may now be advertised for bids. But, as a condition of the project funding, you must not award
the contract or proceed with construction until the Division of Drinking Water has authorized you to do so. This is necessary to comply with applicable requirements and to protect you,
as the funding recipient, by ensuring that the contract meets requirements for funded projects.Federal regulations require that a concerted effort must be made to encourage participation
of small and disadvantaged business enterprises (DBE) by providing requisite information, including plans and specifications on the project. In order to provide opportunities to DBE
subcontractors, utilization goals for Minority-owned Business Enterprises (MBE) and Women-owned Business Enterprises (WBE) have been determined to be 4% and 2%, respectively. As outlined
in the contract documents, the prime contractor must submit a list of prepared MBE/WBE subcontractors to be used on this project and documentation of solicitation efforts with the bid.
The prime contractor's efforts to provide opportunities to DBE's must be reviewed and approved by this office before the contract can be awarded.
If you have any questions regarding this approval, please contact J. Paul Wright, P.E., DEQ Southwest District Office, at [phone], or me at (385) 515‑1464.
Sincerely,
Michael Newberry, P.E.
