Subject:Concurrence, Updated Drinking Water Source Protection Plans for the Kolob Well and Whispering Pines Well #1; Washington County WCD - Kolob Wells; Water System #27097, Source
No. WS001 and WS004
Dear Zachary Renstrom:
The Division of Drinking Water (the Division) received the updated Drinking Water Source Protection (DWSP) plans for the Kolob Well and Whispering Pines Well #1 from you on December
29, 2022.
We have completed our review of the updated DWSP plans and find that the plans basically comply 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. These plans must be updated
often enough to ensure that they reflect current conditions in your protection zones.
The due date for submitting the next updated plan is December 31, 2028.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
Whispering Pines Well #1 (WS004) was previously granted susceptibility waivers for volatile organic contaminants (VOCs) and/or pesticides. However, your updated plan did not provide
a signed waiver for renewal. Monitoring reduction waivers must be renewed every update cycle (six years) to avoid them lapsing. If you would like your reduced monitoring schedule to
remain, please provide a signed sustainability waiver within 90 days of the date of this letter. Please contact Noah Zorsky, P.G., at [phone] or via email at [e-mail]
if you have questions or concerns about the review of your DWSP plan. Contact David Kruse at [phone] or via email at [e-mail] if you have any questions about your monitoring
schedule. To help us serve you more efficiently, please use the water system number (27097) in your correspondence.
Sincerely,
Michael Newberry, P.E.
