a. A
public water system may use point of use (POU) treatment in order to achieve

450.02.b., when the following
conditions are met: (3-24-22)
i. A program for
long-term operation, maintenance, and monitoring of the POU treatment system is
approved by the Department, pursuant to Section
450.02.d. (3-24-22)
ii. The public water system or a vendor of
POU treatment devices under contract with the public water system shall own,
control, and maintain the POU treatment system to ensure proper operation and
maintenance and compliance with the MCL or treatment technique.
(3-24-22)
iii. Each POU treatment
device is equipped with a mechanical warning mechanism to ensure that customers
are automatically notified of operational problems. (3-24-22)
iv. The POU treatment device must be
certified by an accredited American National Standards Institute (ANSI)
certification body to meet applicable ANSI/National Sanitation Foundation (NSF)
Standards. (3-24-22)
b.
POU treatment devices shall not be used to achieve compliance with a MCL or
treatment technique requirement for a microbial contaminant or an indicator of
a microbial contaminant. Community water systems may not use POU treatment
devices to achieve compliance with a nitrate MCL. (3-24-22)
c. The Department will waive the plan and
specification requirements of Section
504 relating to material
modifications for the following systems only to the extent that the material
modification proposed is limited to the installation or use of a POU treatment
device(s): (3-24-22)
i. Community water
systems serving two hundred (200) or fewer service connections.
(3-24-22)
ii. Non-transient
non-community water systems. (3-24-22)
iii. Transient non-community water systems.
(3-24-22)

systems serving more than two hundred (200) service connections if approved by
the Department through the waiver process outlined in Subsection
005.01.a.
(3-24-22)
d. A public
water system must obtain written approval by the Department before installation
of a POU treatment device for the purpose of achieving compliance with a MCL or
treatment technique. The public water system shall submit the following
documentation for approval to the Department: (3-24-22)
i. Information identifying the public water
system name and number, total number of service connections, contaminant(s) to
be treated, type of POU treatment device to be installed, manufacturer and
model number of the POU treatment device, type and function of the mechanical
warning mechanism (performance indicator) on the POU treatment device,
certification verification for ANSI/NSF, installer qualifications, and a
proposed date for installation of the POU treatment device(s).
(3-24-22)
ii. The manufacturer's
specifications for the POU treatment device including demonstration that the
POU treatment device is suited for the water chemistry of the public water
system and contaminant(s) of concern and is of sufficient design and capacity
for the particular application. (3-24-22)
iii. Information relating to how other
drinking water dispensing units, such as instant hot water dispensers and
refrigerator water and ice dispensers, whose primary function is to provide
drinking water, will be provided with treated water. If water is transported
from a POU treatment device to another drinking water dispensing unit, the
conducting tube shall be of non-reactive material. (3-24-22)
iv. For non-transient non-community water
systems and transient non-community water systems, demonstration that the
drinking water dispensing units are located in areas adequate to protect public
health. (3-24-22)
v. Demonstration
that all POU treatment devices are owned, controlled, and maintained by the
public water system or by a vendor of POU treatment devices under contract with

450.02.d.vii.
(3-24-22)
ix. A maintenance plan
that demonstrates how on-going maintenance activities will be performed and on
what frequency, including: frequency of treatment media replacements, frequency

warning device is functional, schedule of planned maintenance activities, plan
of how the system will address unscheduled maintenance problems, and a plan and
method of waste disposal. (3-24-22)
x. Documentation that the system meets the
current requirements for a certified operator pursuant to Section
554. (3-24-22)
