Subject:Operating Permit, Water Tank Rehabilitation - Main Tank (ST001), Castle Gate Tank (ST002), and Cemetary Tank (ST003); Helper City, System #04004, File #13540, SRF #3F1880A
Dear Lenise Peterman:The Division of Drinking Water (the Division) received a request for an Operating Permit for the Water Tank Rehabilitation - Main Tank (ST001), Castle Gate Tank
(ST002), and Cemetary Tank (ST003) from your consultant, Lauren C. Ploeger, P.E. and Franson Engineering on March 14, 2025. The Division issued Plan Approval for this project on October
24, 20230. Division staff conducted onsite final inspections of these tanks on April 8, May 24, and Aug 29, 2024.
Our understanding of the project is the recoating of the City’s three tanks, the Main Tank, the Castle Gate Tank, and the Cemetery Tank which are identified as ST001, ST002, and ST003
respectively. Only one tank at a time was removed from service to be recoated. Each tank was sandblasted and recoated with ANSI/NSF 61-certified material. Each tank was then cured and
disinfected.
We have received the following information for Water Tank Rehabilitation - Main Tank (ST001), Castle Gate Tank (ST002), and Cemetary Tank (ST003):
Certification of Rule Conformance with plan approval conditions by a professional engineer.
Satisfactory bacteriological results as evidence of proper disinfection and flushing.
Water quality data — A volatile organics (VOC) sample from each tank after tank interior coating
We have determined that all conditions for operating permit issuance have been met. On this basis, an Operating Permit for Water Tank Rehabilitation - Main Tank (ST001), Castle Gate
Tank (ST002), and Cemetary Tank (ST003)is hereby issued as constituted by this letter. You may now place Main Tank (ST001), Castle Gate Tank (ST002), and Cemetary Tank (ST003) in service
in your water system.
Increased Volatile Organics Monitoring Requirement
The VOC sample collected from the Cemetary Tank (ST003) detected Ethylbenzene at 1.0 ug/L and Xylenes, total at 5.2 ug/L. Although these results are below respective Maximum Contaminant
Levels (MCLs), the results prompt quarterly VOC monitoring at the Cemetary Tank (ST003) pursuant to R309-205-6(2).
The next VOC sample from the Cemetary Tank (ST003) is due sometime between April 1, 2025, and June 30, 2025. This quarterly requirement will remain in place for a minimum of two quarters.
An updated monitoring schedule can be viewed any time at waterlink.utah.gov under the Water Monitoring section. Please contact David Kruse at (385)-566-7789 or [e-mail] for questions
regarding the source monitoring and reporting requirements for this water system.
Please maintain a copy of this letter with your permanent records for future reference.
