Current through Register 2024 Notice Reg. No. 52, December 27, 2024
(a) In responding to a fecal, vomit, blood
contamination, near-drowning or drowning incident, the pool operator shall
perform the following disinfection procedures:
(1) After a fecal, vomit, blood
contamination, near-drowning, or drowning incident, the pool operator shall
immediately close the affected public pool to pool users. If the public pool is
one of multiple public pools that use the same filtration system, then all
interconnected public pools shall be closed to pool users. No one shall be
allowed to enter the public pool(s) until the disinfection procedures have been
completed.
(2) The pool operator
shall remove contaminating material and discharge the contaminating material
directly to the sanitary sewer or other approved wastewater-disposal process in
accordance with State or local requirements. The pool operator shall clean and
disinfect the item used to remove the contaminating material.
(3) The pool operator shall ensure that the
pH of the public pool water is at 7.5 or lower.
(4) The pool operator shall measure and
maintain the public pool water temperature at 77°F (25°C) or
higher.
(5) The pool operator shall
ensure that the filtration system is operating while the public pool reaches
and maintains the required free-chlorine concentration during the disinfection
process.
(6) The pool operator
shall disinfect the public pool water as follows:
(A) If the contaminating material is a formed
fecal stool or vomit, the pool operator shall maintain the free-chlorine
concentration in the pool at 2 ppm for at least 25 minutes.
(B) If the fecal material is a diarrheal
stool, the pool operator shall raise the free-chlorine concentration in the
pool to 20 ppm and maintain that concentration for at least 12.75 hours. If
that public pool water contains a chlorine stabilizer such as cyanuric acid,
the pool operator shall lower the pH to 6.5 and raise the free-chlorine
concentration in the public pool to 40 ppm and maintain that concentration for
at least 30 hours.
(C) If the
contaminating material is blood, the pool operator shall check the
free-chlorine concentration in the public pool at the time of the incident. If
it is below the required minimum free-chlorine concentration, the pool operator
shall immediately close the public pool until the required minimum
free-chlorine concentration is achieved.
(7) The pool operator shall test the
free-chlorine residual at multiple points to ensure the required free-chlorine
concentration is achieved throughout the public pool water for the entire
disinfection time.
(8) The pool
operator shall replace any affected cartridge filters and shall backwash
noncartridge filters after the disinfection process has been completed. The
pool operator shall ensure the effluent is discharged directly to the sanitary
sewer or other approved wastewater-disposal process in accordance with State or
local requirements. The pool operator shall not return the filter backwash
water to the pool. The pool operator shall replace the filter media if
necessary.
(9) The pool operator
shall not allow pool users back into the public pool until the disinfection
process has been completed and the free-chlorine concentration and pH of the
public pool water have returned to normal operating ranges in accordance with
sections 65529 and
65530.
(b) The pool operator shall immediately
document each fecal, vomit, blood contamination, drowning, or near-drowning
incident and maintain records in accordance with section
65523 as follows:
(1) The date and time of the incident, the
affected pool, the available free-chlorine concentrations, pool temperature,
and pH at the time of the incident, and facts known about the circumstances and
cause of the incident. This information shall also be documented after the pool
operator has completed the disinfection process and again when reopening the
pool to pool users.
(2) Whether the
fecal stool was formed or diarrheal.
(3) The procedures followed in responding to
the contamination incident.
(4) The
number of pool users in the public pool and the length of time between the
occurrence, detection, and resolution of the incident.
