Subject:Updated Drinking Water Source Protection Plans and Waiver Renewal Required for the District Well and Greenfield Well; Summit County Service Area #3; Water System #22105, Source
No. WS001 and WS002
Dear John O’Brien:
The Division of Drinking Water (the Division) has not received updated Drinking Water Source Protection (DWSP) plans for the District Well and Greenfield Well, which were required by
December 31, 2022. Deficiencies (SP04 ACTIVE SOURCE LACKS APPROVED UPDATES TO DWSP) were previously added to the Division’s database and ten (10) Improvement Priority System (IPS) points
assigned (5 points per source).
The District Well and Greenfield Well currently have monitoring reduction susceptibility waivers for pesticides and volatile organic contaminants (VOCs), which means that pesticide monitoring
is only required once every three (3) years and VOC monitoring is only required once every six (6) years. According to R309-600-13(2), if a source's DWSP plan is due and is not submitted
to the Division, its use and susceptibility waivers for the VOC and pesticide parameter groups will expire. Use and susceptibility waivers must be renewed every six years with your updated
source protection plan. Because the Division has not received updated DWSP plans or signed waiver statements, these sources are no longer eligible for susceptibility waivers for pesticides
or VOCs. Please submit updated DWSP plans and a signed waiver statement (attached) within 90 days, or your waivers will lapse, and your monitoring schedule will change. Guidance for
preparing the updated DWSP plan can be found online at https://deq.utah.gov/drinking-water/preparing-source-protection-plans.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 submission 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.Please contact Deidre Beck at [phone] or via email at [e-mail] if you have questions about the source protection requirements.
Contact David Kruse at [phone] or via email at [e-mail] if you have any questions about your current monitoring schedule.To help us serve you more efficiently, please
use the water system number (22105) in your correspondence.

Michael Newberry, P.E.
