for the Canyon Well (WS004); Parowan City; Water System #11010
Dear Kelly Bess Stones:
The Division of Drinking Water (the Division) received the updated Drinking Water Source Protection (DWSP) plans for the Main Canyon Spring and 300 East Well from you on September 29,
2020. The Division requested additional information on December 11, 2023. You provided plan implementation documentation on February 21, 2024.
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 these updated plans. 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 for the 300 East Well is December 31, 2028.
The due date for submitting the next updated DWSP plan for Main Canyon Spring is December 31, 2029.Please be aware that the Division has not received an updated DWSP plan for the Main
Canyon Well (source WS004), which was due by December 31, 2022.A dormant deficiency (SP04 ACTIVE SOURCE LACKS APPROVED UPDATES TO DWSP) has been added to the Division’s database to serve
as a tracking tool and reminder. Failure to correct this deficiency by the required due date (90 days from the date of this letter) will result in five (5) Improvement Priority System
points being assigned. If you have any questions about the points, please contact Jennifer Yee at [phone] or [e-mail] 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.
Monitoring Reduction Waivers
You requested susceptibility waivers for volatile organic contaminants (VOCs) and pesticides for the Main Canyon Spring (WS002). This source is not eligible for susceptibility waivers.
Springs are only eligible for use waivers. However, this source is not eligible for use waivers for pesticides or VOCs because the requirements of R309-600-16(3) have not been met. Highway
143 runs throughout the source protection zones. In general, the presence of residences or roads (other than very limited use roads) through zones one, two or three implies that pesticides
and volatile organic chemicals are used. Your monitoring schedule remains the same. 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 system number (11010) in your correspondence.
Sincerely,
Michael Newberry, P.E.
