(5) incorporate failure-proof features so
that the chemical cannot feed into the PIWF, the piping system, or the water
supply system if equipment or power fails, or if there is not adequate return
flow to properly disperse the chemical.
(c) Disinfectant and cyanuric acid levels
shall meet the following criteria at any time a PIWF is open or in use:

(e)
Forms of chlorine containing stabilizer (cyanuric acid) shall not be used in
indoor PIWFs.
(f) Chemicals used in
a PIWF shall:
(1) be registered and labeled
for use in recreational aquatic facilities, such as pools and spas, by the
United States Environmental Protection Agency (EPA);
(2) be used according to the chemical
manufacturer's instructions for the chemical feed system in use; and
(3) comply with the NSF/ANSI-50 Standard
certification for the chemical feed system.
(g) In addition to maintaining sanitizer,
cyanuric acid, and pH levels as required in this section, and except as
provided in subsections (j) and (l) of this section, PIWFs shall be equipped
with a supplemental water treatment system that will protect the public against
infection by the parasite, Cryptosporidium.
(1) Supplemental water treatment systems for
a PIWF include:
(A) UV light disinfection
installed after filtration;
(B)
ozone;
(C) a NSF/ANSI-50 product,
combination of products, or process to control
Cryptosporidium;
(D) weekly hyperchlorination following the
Center for Disease Control's Recommendations for Aquatics Operators of Treated
Venues "Hyperchlorination to Kill Cryptosporidium" available
on the CDC's website: www.cdc.gov/healthyswimming/; or
(E) an equivalent product, process, or system
approved by the department.
(2) Except as provided in subsections (j) and
(l) of this section, water from a PIWF shall not be combined or circulated with
water of other water features or pools unless:
(A) all of the water either into or from the
PIWF is treated with a supplemental water treatment system prior to combining
or circulating with water from other water features or pools; or
(B) all of the water in the other water
features or pools that is combined or circulated with water from the PIWF is
treated with a supplemental water treatment system.
(h) UV light disinfection systems
shall:
(1) conform to the NSF/ANSI-50 Standard
relating to Equipment for Pools, Spas, Hot Tubs, and Other Recreational Water
Facilities;
(2) provide a validated
dosage confirmed by a third party validation which results in a 3 log kill of
Cryptosporidium;
(3) provide a validated dosage equivalent to
40mJ/cm2 or greater at the end of lamp
life;
(4) include an automatic
audible alarm to warn of a UV light disinfection unit malfunction or impending
shutdown;
(5) be equipped with an
automatic mechanism for shutting off the power to the UV light source whenever
the protective UV unit cover is removed; and
(6) be installed in an enclosure designed to
protect the operator against electrical shock or excessive radiation and that
provides protection from UV exposure.
(i) Ozone disinfection systems shall meet the
standards in the EPA Guidance Manual for Alternative Disinfectants and
Oxidants, EPA Publication 815-R-99-014, April 1999, as amended, available at:
http://www.epa.gov/safewater/mdbp/alternative_disinfectants_guidance.pdf.
(j) Operators of stand-alone PIWFs
constructed prior to May 1, 2010, in addition to maintaining sanitizer,
cyanuric acid, and pH levels as required in this section shall:
(1) implement a supplemental water treatment
system that will protect the public against infection by the parasite,
Cryptosporidium; or
(2) test the water of the PIWF for
Cryptosporidium every 14 days during operation.
(k) Operators of stand-alone PIWFs
constructed or extensively remodeled after May 1, 2010 shall, in addition to
maintaining sanitizer, cyanuric acid, and pH levels as required in this
section, implement a supplemental water treatment system that will protect the
public against infection by the parasite,
Cryptosporidium.
(l) Operators of all PIWFs constructed prior
to May 1, 2010, and that share a water supply, disinfection system, filtration
system, circulation system or any other treatment system that allows water to
co-mingle with a pool, in addition to maintaining sanitizer, cyanuric acid, and
pH levels as required in this section shall:
(1) implement a supplemental water treatment

continually monitors and automatically controls chlorine or bromine levels and
pH, testing for chlorine or bromine and pH of the PIWF water shall be conducted
at least once during each day the PIWF is in operation.
(2) If the PIWF is not equipped with

effective disinfection and maintains the required pH and that continually
monitors and automatically controls chlorine or bromine levels and pH, testing
for chlorine or bromine and pH of the PIWF water shall be conducted at least
twice a day, once immediately prior to opening the PIWF and once midway through
