Dear Matthew MacKay:
The Division of Drinking Water (the Division) received the updated Drinking Water Source Protection (DWSP) plan for the Birch Spring, Watercress Spring, Lower Grotto Spring, Upper Grotto
Spring, and Wylie Spring from you, on March 17, 2025.
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.

updated source protection plan, by submitting an updated waiver statement. If the update is not received, your waivers may lapse, and your monitoring schedule will change.Please contact
