Subject:Concurrence, Updated Drinking Water Source Protection Plan for the Upper and Lower Springs; Charleston WCD; Water System #26003, Source No. WS001 and WS002
Dear Janet Winters:
The Division of Drinking Water (the Division) received the updated Drinking Water Source Protection (DWSP) plan for the Upper and Lower Springs from the Rural Water Association of Utah
on July 21, 2021. The Division requested additional information via email on November 3, 2023 and February 6, 2024. Your consultant, Tavis B. Timothy, P.E., provided revisions to the
plan on June 12 and June 13, 2024.
We have completed our review of the updated DWSP plan and find that the plan basically complies with the applicable portions of Utah’s Administrative Rules for Public Drinking Water
Systems. The Division concurs with this updated plan. We commend you for establishing a program to protect these sources from present and future contamination. This plan must be updated
often enough to ensure that it reflects current conditions in your protection zones.
The due date for submitting the next updated plan is December 31, 2029.RemindersAs stated in R309-600 and 605: Implementing DWSP Plans - Each Public Water System (PWS) shall begin implementing
each of its DWSP Plans in accordance with the implementation schedule within 180 days after submittal if the plan is not disapproved. Be prepared to describe these efforts in your next
update, which should include documentation of how the land management strategies identified for existing and future potential contamination sources were implemented. Your updated plan
will be disapproved, and 25 Improvement Priority System (IPS) points will be assigned for failure to comply with this requirement.As stated in R309-600 and 605: Recordkeeping - As a
DWSP Plan is executed, the PWS shall document any land management strategies that are implemented. Please provide actual copies of memoranda of understanding, public education programs,
bill stuffers, newsletters, or other correspondence documenting the implementation of each land management strategy as it occurs, in this section of your updated plan.
Monitoring Reduction Waivers
You requested use waivers for volatile organic contaminants (VOCs) and pesticides. Grouped Sampling Station -01 02 (SS190) (Upper and Lower Springs) is not eligible for use waivers for
VOCs or pesticides because the requirements of R309-600-16(3) cannot be met. Cascade Springs Drive runs throughout source protection zones two and three, which indicates that VOCs and
pesticides are transported and/or used in these zones. Therefore, these sources are no longer eligible for use waivers. SS190 is eligible for a reliably and consistently waiver for VOCs
so your sampling requirements have only been increased for pesticides. The source monitoring requirements for these springs are given in the table below, and are also available to view
anytime online at waterlink.utah.gov.Facility with new requirementsAnalyte(s) Required# of samplesSampling FrequencyNext Due DateRule ReferenceWS001 and WS002 (SS190)Inorganics & Metals1Every

A single pesticide sample collected from Sampling Station - 01 02 (SS190) is due by September 30, 2024. If the results show no detections, then another pesticide sample will not be due
for another three years. Please contact David Kruse at [phone] or via email at [e-mail] if you have any questions about your monitoring schedule.Please contact Deidre
Beck at [phone] or via email at [e-mail] if you have questions or concerns about the review of your DWSP plan. To help us serve you more efficiently, please use the water
