Subject: Corrective Action Plan Extension for Timpanogos Cave, UTAH25105 (2024-01)

Dear Ray Solorio:

The Division of Drinking Water (the Division) has received your request for an extension to the
Corrective Action Plan granted to Timpanogos Cave on September 27, 2024. The request for the
extension is due to the deep-rooted vegetation located in a forest service area. The water system is
applying for an exception. Please review the extension agreement and sign the attached agreement.
Once the extension agreement has been signed by the water system and the Division, then a copy
of the fully executed document will be returned to you.

Please contact Brandi Smith at [phone] or [e-mail] if you have any questions
regarding this letter or the enclosed copy of Corrective Action Plan.

Sincerely,

Helen Lau
Compliance and Operations Manager
Division of Drinking Water
