Subject: Notice of Decreased Monitoring for Wasatch Peaks Ranch, UTAH15044 Nathan Anthony Bell:
This letter serves as notification that quarterly monitoring for radionuclides is no longer required from the Well A2 (identified as WS003). A radionuclide sample collected from the Well A2 (WS003) is now required once every six years. The next radionuclide sample is due sometime between April 1, 2026 and June 30, 2031.
Following the issuance of an operating permit the Well A2 (WS003) was placed on a quarterly monitoring requirement to fulfill the initial monitoring requirements given in R309-205-7(1)(b). A sufficient number of radionuclide samples have been collected to qualify this source for reduced monitoring.
The updated source chemical monitoring requirements for the Well A2 (WS003) are given below and are available to view anytime on waterlink.utah.gov. Please contact David Kruse at [e-mail] or 385-566-7789 for questions regarding the source chemical monitoring requirements for this system.
