Current through Bulletin 2024-06, March 15, 2024
(1) The operator shall ensure that:
(a) a geothermal
pool or geothermal bathing place has a temperature measuring device that is;
(i) accurate to within one degree Fahrenheit;
and
(ii) calibrated in accordance
with the manufacturer's specifications as necessary to ensure its
accuracy;
(b) the
geothermal pool water temperature is measured at the warmest point;
(c) the geothermal pool water temperature is
maintained at a maximum of 104 degrees Fahrenheit; and
(d) a geothermal pool or geothermal bathing
place that exceeds 104 degrees Fahrenheit at the minimum required turnover rate
has, and employs when necessary, one or more of the following approved methods
of temperature reduction in the pool or bathing place that maintains the
minimum flow-through rate required under Subsection
R392-303-19(1):
(i) introduction of cool water from a source
that has been analyzed and approved according to Section
R392-303-6, or approved for
drinking water by the Utah Division of Drinking Water;

water by a heat exchanger; or
(iii)
the diversion of the geothermal source water to allow it to cool prior to
entering the pool or impoundment; and
(e) the temperature reduction method is
capable of reducing the temperature of the pool within two hours of activation
from the maximum anticipated temperature to below 104 degrees
Fahrenheit.
(2) If the temperature of the source water or cooling rate of the geothermal pool is difficult to control, a temperature drift of up to four degrees Fahrenheit is allowed if temperature reduction measures in Subsection (1)(d) have been activated; and the temperature is not above 108 degrees Fahrenheit.
(3) If a soaking tub or similar fixture with a volume of 70 gallons or less is used, the water temperature shall not exceed 110 degrees Fahrenheit.
