Dear Kevin Anderson: The Division of Drinking Water (the Division) received your request for the Operating Permit for the Harvey Well Deepening Project from your consultant, Scott Greenhalgh,
P.G. andHansen, Allen & Luce Engineers on December 19, 2024. The Division issued Plan Approval for deepening this well on July 19, 2022. Division staff conducted an onsite inspection
of this project on November 25, 2024.
Our understanding of the project was the deepening of the existing Harvey Well originally drilled in 1961 to a depth of 510 feet. A new 10-inch diameter mild steel casing was drilled
to a new depth of 810 feet. The 10-inch casing was perforated and cut off at 495 feet below ground level. The original 14-inch screen and casing was removed, and new 12-inch stainless-steel
wire-wrap screens were installed from 380 feet to 480. A stainless-steel blank casing was installed from 480 feet to 500. A stainless-steel blank casing was installed on top of the screens
from 340 feet to 380 feet with mild steel blank casing extended to the surface. A 6-9 gradation artificial filter pack was installed between the existing 16-inch and the newly installed
12-inch liner. The well was redeveloped using a dual-swab tool and test pumped with a line-shaft turbine pump. A constant rate test was performed at 1,500 gallons per minute (gpm) with
a sustained drawdown of approximately 6 feet. The original wellhouse equipment was reinstalled for the project. The Harvey Well is identified as WS002in the Division’s database.
We have received the following information for Harvey Well Deepening Project:
Design engineer’s statement of conformance with approval conditions
Evidence of O&M manual delivery.
As-built or record drawings.
Satisfactory bacteriological results as evidence of proper disinfection and flushing.
We have determined that all conditions of operating permit issuance have been met. On this basis, an Operating Permit forHarvey Well Deepening Project is hereby issued as constituted
by this letter. You may now place the Harvey Well (WS002), in service in your water system.
Please maintain a copy of this letter with your permanent records for future reference.
The equipped well pump capacity of the Harvey Well is 1,500 gallons per minute (gpm). The safe yield of the Harvey Well is rated at 1,000gpm, which is calculated based on two-thirds
of the constant-rate aquifer drawdown test results at 1,500gpm. The safe yield of 1,000gpm is the basis for determining the maximum number of connections that the Harvey Well can serve.
Revised Drinking Water Source Protection Plan Requirement
A revised Drinking Water Source Protection (DWSP) plan is required within 180 days after the reconstruction or redevelopment of any groundwater source of drinking water (refer to R309-600-7(3)(f)).
The revised plan must address changes in source construction, development, hydrogeology, delineation of the source protection zones, the potential contamination source inventory, etc.,
as applicable. The revised delineation should address any increase in saturated aquifer thickness or change in the maximum (equipped) pumping rate, if applicable. If this project does
not result in changes that would affect the delineation, please send an email to Deidre Beck at dbeck@utah.gov, indicating the project did not result in changes that would affect delineation
of the source protection zones.
A dormant deficiency (SP07 - ACTIVE SOURCE LACKS AN APPROVED DWSP PLAN) has been added to the Division’s database to serve as a tracking tool and reminder. Failure to correct this deficiency
by the required due date (90 days from the date of this letter) will result in 25 Improvement Priority System (IPS) points being assigned as well as a treatment technique violation as
stated in R309-215-16(4)(a). If you have questions about these points, please contact Jennifer Yee at (385) 515-1501 or ddwips@utah.gov. If you cannot address the deficiency within 90
days, please request a Corrective Action Plan (CAP) at requestcap.utah.gov. If you have questions about requesting a CAP, please contact Brandi Smith at brandismith@utah.gov. If you
have questions about the source protection requirements, please contact Deidre Beck at (385) 271-7046.
Source Monitoring Requirements
Issuance of this Operating Permit changes your water system’s monitoring and reporting
requirements. The monitoring requirements for this well are given below. An updated monitoring schedule can be viewed any time at waterlink.utah.gov under the Water Monitoring section.
Please contact David Kruse at (385)-566-7789 or dbkruse@utah.gov for questions regarding the source monitoring and reporting requirements for your water system.Facility with new requirementsAnalyte(s)

used for testing. Please ensure that the chosen laboratory processes PFAS samples using one of these methods. Additionally, the Division has resources to assist water systems in completing
the PFAS initial monitoring requirements. For more information on the resources the division can provide related to PFAS initial monitoring please visit ddwpfas.utah.gov. For PFAS related
questions, please contact John Steffan at jtsteffan@utah.gov or (385) 499-3926.
