Current through Bulletin 2024-06, March 15, 2024
(1) The operator
shall ensure that:
(a) a geothermal pool or
geothermal bathing place that transports source, pool, or discharge water
through pipes meets the requirements of Section
R392-302-16 for piping, pipe
labeling, velocity in pipes, adequate space in equipment areas, valves, and air
induction systems;
(b) a geothermal
pool or geothermal bathing place meets the requirements of Section
R392-302-16 for normal water
level and vacuum cleaning systems except a vacuum cleaning system is not
required if an operator keeps the pool clean by draining the pool and cleaning
it while it is empty; and
(c) a
geothermal pool or geothermal bathing place maintains flow-through 24 hours a
day during the operating season, except for periods of maintenance.
(2) If the geothermal pool or
geothermal bathing place is drained and cleaned each day prior to use,
flow-through is only required during the period that the geothermal pool or
geothermal bathing place is in use.
(3) The operator shall ensure that:
(a) a geothermal pool or geothermal bathing
place with a volume greater than 3,000 gallons has a flow-through rate greater
than or equal to 1/4 the pool volume every hour;
(b) a geothermal pool or geothermal bathing
place with a volume less than or equal to 3,000 gallons has a flow-through rate
greater than or equal to the complete pool volume every 30 minutes;
(c) a geothermal pool or geothermal bathing
place has a method to determine accurate rate of flow in gallons per minute;
(i) if the rate of flow method is a rate of
flow indicator manufactured by a third party, it is properly installed and
located according to the manufacturer's recommendations; or
(ii) if a field-fabricated rate of flow
indicator such as a calibrated weir or flume is used, it is designed and
calibrated under the direction of a licensed professional engineer;
and
(d) the rate of flow
indicator is located and positioned in a place where it can be easily read by
the operator as required in Subsection
R392-302-16(6).
(4) If the operator of a
geothermal pool or geothermal bathing place maintains the disinfectant levels,
chloramine levels, and pH levels within the values allowed in Table 6 of Rule
R392-302 and operates a recirculation system in the pool in compliance with the
requirements of Section
R392-302-16, the pool is exempt
from the flow-through rate requirements of Subsection R392-303-19(1).
(5) The local health officer may:
(a) approve a reduced flow rate if the
operator can demonstrate that the required bacteriological level can be
maintained at the reduced flow rate; or
(b) exempt a geothermal pool or geothermal
bathing place from the requirement for a rate of flow indicator if the rate of
flow is not adjustable or if there is no practical way to measure
flow.
(6) If the
operator of a geothermal bathing place is unable to control the flow-through
rate, the operator may meet the bacteriologic water quality standards in
Section R392-303-26 by controlling bather load.
(7) Except the operator shall maintain a
flow-through with a maximum turnover time of 48 hours, and shall meet the
bacteriologic requirements of Subsection
R392-302-27(6)(d).
