Director October 22, 2025 CERTIFIED MAIL Lisa Chauvin Dammeron Valley Water Works LLC 1 Dammeron Vly East Dammeron Valley, UT 84783 Subject: NOTICE OF VIOLATION – Failure to Fix Significant Deficiency Treatment Technique Violation, Water System #UTAH27030 Lisa Chauvin: Our records indicate that your system is in violation of the State of Utah Public Drinking Water Rules as follows: On May 8, 2025, Dammeron Valley Water Works LLC received three significant deficiencies. The system was notified of these deficiencies on May 10, 2025. Two of these deficiencies remain uncorrected: • V011 End of storage tank overflow lacks a clearance of between 12 and 24 inches from ground surface ST002 • V011 End of storage tank overflow lacks a clearance of between 12 and 24 inches from ground surface ST003 Utah Public Drinking Water Rules require all significant deficiencies to be corrected within 120 days of the date of notification or the system must enter a corrective action plan (CAP) with the Division to address the significant deficiencies as specified in R309-215-16(3)(a)(v). The system chose not to request a corrective action plan or submit a correction for this deficiency within the given timeframe. This results in the system being assessed a treatment technique violation in accordance with R309-215-16(4)(a) and the assessment of 50 Improvement Priority System (IPS) points to the system’s IPS Report. Be advised this could adversely affect your water system’s rating (R309-400). As a result of this Tier 2 violation, the system must provide public notice as soon as practical, but no later than 30 days after the system learns of the violation. If the public notice is posted, the notice must remain in place for as long as the violation or situation persists, but in no case for less than seven days, even if the violation or situation is resolved (see R309-220-6(1)(a) and R309- 220-6(1)(b)). This public notice requirement cannot be waived once a violation occurs. Proof of Lisa Chauvin Page 2 of 2 public notification must be provided to the Division at (ddwreports@utah.gov) within 30 days of notifying the water system customers and resubmitted each quarter the deficiencies remain unresolved. Failure to submit quarterly public notification may result in a public notice violation and an additional 50 points on the IPS report. If any of the above deficiencies have been corrected, please complete the enclosed IPS Deficiency Correction Notice and submit the information to the Division at ddwips@utah.gov immediately. We ask that you respond to this letter as soon as possible. Please contact Jennifer Yee at (385) 515-1501 or ddwips@utah.gov if you have questions or need assistance.
