Subject:TemporaryException Renewal to R309-515-6(12)(e), R309-515-6(12)(d)(v), and R309-510-8, for means to measure water levels, means to release trapped air, and storage capacity requirements,

Zollinger Warehouse, System #03052, File #12810
This Temporary Exception Expires on December 31, 2027.
Dear Lance Zollinger:
On December 8, 2021, the Division of Drinking Water (the Division) originally issued an exception to Rule R309-515-6(12)(e), R309-515-6(12)(d)(v), and R309-510-8 regarding means
to measure water levels, means to release trapped air, and storage capacity requirements,
respectively for the artesian Zollinger Well (WS001).
Zollinger Warehouse is a non-transient system that operates year-round. The system serves, at
most, 170 employees on-site during an approximate 8-hour shift. The water system provides
drinking water to offices and industrial buildings for restrooms. No showers or cafeterias are
present within the water system. The Zollinger Well (WS001) is an artesian well and provides all
the water for the water system. A bucket flow test conducted throughout the system in October
2021, the well produces 10 to 12 gallons per minute (gpm). However, this was performed throughout the distribution system because the sample tap caused the bucket to boil over due to
pressure and flow. Most realistically the flow is higher at the well. The system currently does not have any drinking water storage. Since the first issuance of the exception, the system
has continued collecting monthly samples throughout the distribution system.
Exception Request
The basis for your request for an exception to R309-515-6(12)(e) and R309-515-6(12)(d)(v) is that the well is an artesian well. The water level is always under pressure in the distribution
pipe without the use of a pump. Thus, there is no water level to measure and no need to put means in
place to measure the water level in the well. Second, the system is a closed system that is always
under constant pressure. There is no point in the well where air would be introduced since it is
always flowing.
The basis for your request for an exception to R309-510-8 is that the peak day demand is less than
the capacity of the well. The well only provides indoor water to the Zollinger Warehouse. Using the source demand from Table 510-2 in R309-510-7, the peak day flow is 5.3 gpm. This was
determined by using the 15 gpm/employee/day and the maximum number of 170 employees. This results in 2,550 gpd/shift. There is only one approximately 8-hour shift per day. Therefore,
the demand is 318.75 gal/hr or 5.3 gpm. This is less than the capacity of 10-12 gpm found in the system. The well should be able to provide the flow required in the system without additional
equalization storage. Further, if the system was unable to provide water for any reason, they could not provide water until the well supply was restored. Further, employees have been
gathering bucket test flow data every month to verify the flow of the artisanal well is above the 5.3 gpm.
On this basis, exceptions to R309-515-6(12)(e), R309-515-6(12)(d)(v), and R309-510-8 for
means to measure water levels, means to release trapped air, and storage capacity
requirements, respectively, are hereby renewed for the Zollinger Well (WS001).
This Temporary Exception expires on December 31, 2027.
You must continue to measure and record the Zollinger Well (WS001) flow once a month and submit to the Division for the renewal of these exceptions.
You will be required to re-submit an exception request along with confirmation that all conditions outlined in this temporary exception have been fulfilled and obtain an exception renewal
prior to December 31, 2027.
Exceptions granted by the Division include an expiration date to ensure that the basis and conditions for granting the exception are verified periodically and that the drinking water
quality remains protected. After receiving your request, the Division will determine whether this exception can be re-issued.
Failure to request the re-evaluation of this exception and obtain an exception renewal by Month Day, Year, will result in the activation of the deficiency related to not being able to
measure the water levels, release trapped air, and lacking storage capacity requirements.
This Temporary Exception may be rescinded any time if new evidence indicates that the conditions of this exception are no longer being met or a public health risk exists due to this
exception.The issuance of this exception temporarily resolves your water system’s deficiencies: S015: Welllacks means to measure water levels; S026: No flow meter on well discharge piping;
and SL01:well lacks a means to release trapped air.An updated IPS report is available 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.
Please maintain a copy of this letter with your permanent records for future reference.
If you have any questions regarding this temporary exception, please contact Dani Zebelean, P.E., of this office, at [phone], or Michael Newberry, P.E., Permitting and Engineering
