Utah Admin. Code R309-535-12 - Point-of-Use and Point-of-Entry Treatment Devices
Where drinking water does not meet the quality standards of R309-200 and the available water system treatment methods are determined to be unreasonably costly or otherwise undesirable, the Director may permit the public water supplier to install and maintain point-of-use or point-of-entry treatment devices. This approval shall only be given after receipt and satisfactory review of the following items.
(1) The Director shall only consider
approving point-of-use or point-of-entry treatment upon receipt of an analysis
that clearly demonstrates that central treatment is not feasible for the public
water system. Unless waived by the Director, this analysis shall be in the form
of an engineering report prepared by a professional engineer registered in the
State of Utah. Systems serving fewer than 75 connections are excused from
performing an analysis by a Registered Professional Engineer.
(2) The water system shall have a signed
access agreement with each customer that allows water system personnel to enter
their property on a scheduled basis to install and maintain the treatment
devices. The agreement shall include educational information with regard to the
health risks of consuming or cooking with water from non-treated taps. Systems
with an initial 75% of their connections under a signed access agreement shall
be allowed to proceed with the understanding that 100% of their connections are
due within a 5 year period. For public water systems that own or control all
connections to the public water system, this requirement will not
apply.
(3) Documentation that legal
authority, which includes a termination of service clause, has been adopted to
ensure water system access to the property for installation, maintenance,
servicing and sampling of each treatment unit. For public water systems that
own or control all connections to the public water system, this requirement
will not apply.
(4) Point-of-use or
point-of-entry treatment devices used shall only be those proven to be
appropriate, safe and effective as determined through testing and compliance
with protocols established by EPA's Environmental Technology Verification
Program (ETV) or the applicable ANSI/NSF Standard(s). A pilot study may be
required to determine the suitability of the point-of-use or point-of-entry
device in treating a particular source water. The scope and duration of the
pilot study shall be determined by such factors as the characteristics of the
raw water, manufacturer's ratings of the treatment device, and good engineering
practices. The pilot study will generate data on service intervals, aid in
specifying and calibrating alarm systems, and reveal any site specific problems
with component fouling or microbial colonization.
(5) The water system shall provide an
operation and maintenance plan demonstrating that the treatment units shall be
installed and serviced in accordance with the manufacturer's instructions and
that compliance sampling as required in
R309-215-6
shall take place. The system shall provide documentation of an operation and
maintenance contract or schedule annually as required in
R309-105-16(4).
If the operation and maintenance of the POU/POE devices is performed by water
system personnel, it shall only be performed by a water operator certified at
the level of the water system.
(6)
The performance indicating device for the point-of-use/point-of-entry treatment
device that will be used shall be specified in the submital for plan
approval.
(7) The water system
shall submit a customer education and out-reach plan that includes at a minimum
annual frequency of contact.
(8)
Point-of-use or point-of-entry treatment devices for compliance with the
nitrate MCL shall only be considered if treatment is provided at all taps that
are accessible to the public.
