Dear Christopher Swenson & Garry Heinze:

Subject: Corrective Action Plan Closure UTAH10022-2025-01

On June 6, 2025, Arches National Park-Devils Garden and the Division of Drinking Water entered into a
Corrective Action Plan (CAP). As of October 31, 2025, Arches National Park-Devils Garden has
successfully completed the requirements listed in the CAP. The CAP is now officially closed, and the water
system’s rating will remain at an approved status with 70 Improvement Priority System (IPS) points.

The Division of Drinking Water recognizes that addressing deficiencies and violations can be difficult and
often requires significant financial and personnel resources. We would like to thank Arches National Park-
Devils Garden Water for the efforts put forth in resolving the items, for your continued commitment to
maintaining reliable infrastructure, and for ensuring the safety of the drinking water provided to your
customers.

Please find enclosed current copies of the completed CAP requirements, monitoring schedule, and IPS report
to help Arches National Park-Devils Garden maintain compliance and an approved status. If you have any
questions, please contact Brandi Smith at [phone] or [e-mail].

If there is ever anything we can do to support you in your role of protecting public health, please contact us.

Sincerely,

Helen Lau
Compliance and Operator Assistance Section Manager
Division of Drinking Water
