Subject:Operating Permit, Rest Stop Spring Rehabilitation (WS001);
Shingle Creek Highway Rest Stop, System #13011, File #12214
Dear Ryan Ellsworth:The Division of Drinking Water (the Division) received your request for a (Permanent) Operating Permit for the Shingle Creek Highway Rest Stop with your submittal
of 3 years of spring flow data on September 5, 2024. The Division issued a Temporary Operating Permit for this project on August 27, 2021. The Department of Environmental Quality Southwest
District Engineer conducted an onsite final inspection of this project on June 29, 2021.
Our understanding of the project was the rehabilitation of the spring collection area for the Rest Stop Spring (WS001). This included the demolition of the existing spring collection
culvert; removal of deep-rooted vegetation throughout the fenced area; new fencing to establish a proper protected spring area; re-establishment of collection lines with impermeable
liner and cover; and the construction of a new collection manhole with an overflow, hatch, air vent, and a flow measurement weir and staff gauge.
The Temporary Operating Permit issued in 2021 was conditional upon you collecting 3 years of
monthly spring flow data and submitting that data before December 31, 2024. That spring flow
data has been received and reviewed to establish the safe yield of Rest Stop Spring (WS001).
We previously received the following information for the Rest Stop Spring Rehabilitation:
Design engineer’s statement of conformance with approval conditions.
As-built or record drawings.
Satisfactory bacteriological results as evidence of proper disinfection and flushing.
Permanent Operating Permit for Rest Stop Spring (WS001)
We have determined that all conditions of issuing an Operating Permit have been accomplished. On this basis, a PermanentOperating Permit for Rest Stop Springis hereby issued as constituted
by this letter.
Please maintain a copy of this letter with your permanent records for future reference.The yield of Rest Stop Spring (WS001) is determined to be 3.6 gallons per minute (gpm) based on
the spring flow information we received. This yield is the basis for determining the maximum number of connections that the Rest Stop Spring can serve.
Bacteriological Source Sampling
This system is required to take monthly Escherichia Coli (E. coli) sampling at Water Rest Stop Spring (WS001) (assessment monitoring) during the operating period when the spring is accessible
and shall continue for a minimum of 6 months. This schedule will begin April 2025.
This sample is in addition to the monthly distribution system sample (DS001). Please label the source sample as WS001 (for both the facility ID and sample point ID) on all laboratory
forms.
Please contact Sitara Federico for any positive samples that may occur at the source at 385-515-1459 or [e-mail]. If any sample result comes back as E. coli positive, please
contact the Division within 24 hours of being notified of the result.
This monitoring is required to evaluate the quality of the water coming from Rest Stop Spring (WS001) to better protect public health. Additional monitoring and/or disinfection requirements
may be assigned depending on the results of the assessment monitoring.Since this Permanent Operating Permit changes some of your monitoring requirements, the staff of the Water Quality
Monitoring and Standards Section will follow up to provide an updated monitoring schedule to you. Please contact the Mark Berger, Water Quality Monitoring and Standards Section Manager
at [phone] for questions regarding the monitoring and reporting requirements for your water system.The issuance of this Operating Permit resolves your water system’s deficiency
of 200 points (S001) related to submitting 3 years of flow data from Rest Stop Spring (WS001). An updated IPS report isavailable at https://waterlink.utah.gov. Please contact Jennifer
Yee at [phone] or [e-mail] for questions related to your water system’s IPS report or deficiencies.
If you have any questions regarding this Operating Permit, please contact J. Paul Wright, P.E., DEQ Southwest District Office, at [phone], or Michael Newberry, Engineering Manager,
