Current through Register Vol. 51, No. 3, September 1, 2024
NECESSITY, FUNCTION, AND CONFORMITY:
KRS
211.190(11) requires the
Cabinet for Health and Family Services to provide public health services that
include water fluoridation programs for the protection of dental health. This
administrative regulation establishes the requirements for the programs.
Section 1. Definitions.
(1) "Cabinet" is defined by
KRS
194A.005(1).
(2) "Consecutive supply" means a supply that
purchases its water from another water system.
Section 2. Community Implementation. The
population served by a water system includes its own population and the
population served by its consecutive supplies.
(1) A water system serving a community
population of 3,000 or more, including consecutive supplies, shall adjust
fluoride-deficient waters to protect the dental health of the people served by
the supply.
(2) A water system
serving a population between 1,500 and 3,000 shall provide supplemental
fluoridation only if adequate fluoride feed equipment is available from the
cabinet, Department for Public Health.
(3) Although not required to provide
supplemental fluoridation, a water system serving a population of less than
1,500 that chooses to provide supplemental fluoridation shall do so only if:
(a) Adequate fluoride feed equipment is
available from the cabinet, Department for Public Health; and
(b) There are competently trained or
certified personnel at the water system.
Section 3. Approval. A water system shall
obtain the written approval of the cabinet before adding fluoride to a public
water system, pursuant to Section 5 of this administrative
regulation.
Section 4. Equipment,
Facilities, and Services. The equipment, facilities, and services shall meet
the requirements set forth in this section.
(1) Feeding. Feeding equipment with an
accuracy within five (5) percent shall be provided to feed the optimal dosage
of fluoride.
(a) The rate of feed shall give a
fluoride content operating tolerance range between six-tenths (0.6) ppm and one
and two-tenths (1.2) ppm in the treated water, with an optimal concentration of
seven-tenths (0.7) ppm.
(b) The
point of application shall be selected so that fluoride is evenly mixed with
the water leaving the treatment plant.
(2) Method of measurement.
(a) Saturator tanks. If solution feed
equipment is used, the water plant shall have a corrosion-resistant solution
tank and an accurate means for weighing the stock chemical (fluoride)
available. A metering device for measuring the water for the solution shall
also be used.
(b) Dry feed hoppers.
Dry feed hoppers shall be mounted on scales.
(c) Acid systems (H2SiF6). Scales shall be
available to measure the weight loss each day or a volumetric method of
measuring the amount of acid being used each day shall be used.
(3) Protection of operator.
Precautions shall be taken to protect the operators. Precautions shall include:
(a) An approved respirator;
(b) Approved rubber gloves;
(c) An eye shield;
(d) An apron; and
(e) An exhaust or ventilation system for all
fluoride feeding equipment.
(4) Storage. Separate storage areas shall be
used for all fluoride chemicals.
(5) Laboratory facilities. Laboratory
facilities shall be used for the determination of the fluoride content of the
water by personnel in accordance with the current standards published by the
American Public Health Association, the American Water Works Association, and
the Water Pollution Control Federation.
(6) Samples. Raw water and plant tap water
samples shall be examined at least once per day and the results shall be
included on the monthly operation report submitted to the Energy and
Environment Cabinet in accordance with
401
KAR 8:020.
(a)
Additional finished water samples shall be analyzed by a laboratory certified
by the Energy and Environment Cabinet in accordance with
401 KAR
8:040 for fluoride determination, with the results
being forwarded by the water system to the cabinet, Department for Public
Health.
(b) This sampling shall be
at a rate of two (2) samples per month.
(c) The first sample shall be collected from
the plant tap during the first week of the month and the second sample
collected from the distribution system, at a point of maximum retention, during
the third week of the month.
(7) Siphon breakers. Fluoride feeders shall
be equipped with siphon breakers to prevent back siphonage of concentrated
fluoride solution into the distribution system.
(8) Notification of cabinet when fluoride
begins. The cabinet shall be notified of the date on which fluoridation is to
commence in order that a representative of the cabinet may be present to
calibrate and check the fluoridation equipment and instruct the operating
personnel concerning tests, records, operation, and safety
precautions.
(9) Notice when
fluoride is interrupted. The owner or operator of the water plant shall
immediately notify the cabinet of any interruption to the addition of fluoride
to the water supply.
Section
5. Procedure for Obtaining Approval. A system shall submit to the
cabinet:
(1) Detailed plans showing the method
and point of application of fluoride and storage facilities for stock
chemicals;
(2) Information
concerning technical supervision of the treatment process;
(3) Information on the provisions for
laboratory facilities; and
(4)
Evidence that the plant facilities and operation will provide for:
(a) Control and supervision;
(b) Safe operation and maintenance;
(c) The keeping of operational records;
and
(d) Compliance with this
administrative regulation and
401 KAR
8:010 through
401 KAR 8:700
relating to public water systems.
