Subject:Operating Permit, Courthouse Wash Well Iron Removal Water Treatment Plant (TP001); Utah Raptor State Park, System #10050, File #13419
Dear Brad Walker:The Division of Drinking Water (the Division) received a request for an Operating Permit for the Courthouse Wash Well Iron Removal Water Treatment Plant from your consultant,
Jonathan Johansen, and J&T Engineering on April 10, 2025. The Division issued Plan Approval for this project on February 6, 2024. Division staff conducted a final inspection of this
project on April 9, 2025, and additional photos of key features of the treatment system were provided.
Our understanding of the project is that Well #2 (WS002) has iron and manganese levels just below the secondary maximum contaminant level (MCL). A filtration system with four pressure
filters containing greensand plus media with an anthracite cap was installed to treat the iron and manganese levels in Well #2 (WS002). Treatment is facilitated with a pre-oxidation
step using liquid sodium hypochlorite. A chlorine residual is maintained through the treatment process to provide a detectable residual in the distribution system. A chlorine analyzer
is installed after the filters and the pump skid. A detailed project description is summarized in the Plan Approval (Project Overview Addendum) issued on February 6, 2025. The Courthouse
Wash Well Iron Removal Water Treatment Plant is identified as TP001 in the Division’s database.
We have received the following information for Courthouse Wash Well Iron Removal Water Treatment (TP001):
Certification of Rule Conformance with plan approval conditions by a professional engineer.
As-built or record drawings.
Satisfactory bacteriological results as evidence of proper disinfection and flushing.
Evidence of O&M manual delivery.
Water quality data — Iron and manganese samples were collected from the pre- and post-filtration sample taps. The pre-filtration sample has an iron and manganese result of 0.72 mg/L
(ppm) and 0.0243 ppm, respectively. The post-filtration sample has an iron and manganese result of non-detect and 0.0026 ppm, respectively.
We have determined that all conditions for operating permit issuance have been met. On this basis, an Operating Permit for Courthouse Wash Well Iron Removal Water Treatment (TP001) is
hereby issued as constituted by this letter. You may now place the Courthouse Wash Well Iron Removal Water Treatment (TP001) in service in your water system.
Please maintain a copy of this letter with your permanent records for future reference.
Issuance of this Operating Permit changes this water system’s monitoring and reporting
requirements. The monitoring requirements for this treatment plant are given below. Please collect all samples listed from a location which represents the well water after it has undergone
treatment, but before it has entered into the distribution system. 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 [e-mail] for questions regarding the source monitoring and reporting requirements for this water system.Facility with new requirementsAnalyte(s)

and Resources:The EPA rule for PFAS requires that either method 533 or 537.1 version 2 are 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 [e-mail] or [phone].
If you have any questions regarding this Operating Permit, please contact Chris Martin, of this office, at [phone], or Michael Newberry, Permitting and Engineering Manager, at
