AN ORDINANCE TO REGULATE THE INSTALLATION AND
CLEANING OF CLEANED -IN -PLACE MILK PIPELINE SYSTEMS
ON DAIRY FARMS, - REQUIRING A PERMIT FOR THE INSTALL-
ATION OF PIPELINE SYSTEMS, PROVIDING A PENALTY FOR
VIOLATION, DECLARING AN EMERGENCY, AND FOR OTHER
PURPOSES.
BE IT ORDAINED BY THE BOARD OF DIREECTORS OF THE CITY OF LITTIE ROCK, ARKANSAS:
SECTION 1. DEFINITIONS.
The following definitions shall apply in the interpretation and
enforcement of this ordinance.
A. C.I.P. MILK PIPELINE SYSTEM.
This term, for the purpose of this ordinance, shall include the
milk pipeline, releaser, milk pump, milk receiver, milk tubes, and milker units
and similar appurtenances.
B. PRESSURE SYSTEM OF C.I.P. PIPELINES.
This system is for cleaning the pipelines by forcing a sufficient
volume of solutions, beginning and ending in the milk room, through the system
by pressure, produced by a pump of sufficient capacity, to effectively clean
the system.
C. VACUUM SYSTEM OF C.I.P. PIPELINES.
This system is for cleaning the pipelines where a return circulat-
ing line is used., by repeatedly drawing the cleaning solution through the pipe-
lines and returning it to the circulating unit located in the milk room.
D. VACULE- GRAVITY SYSTEM OF C.I.P. PIPELINES.
This system is for cleaning a single run of pipelines, where no
return line is used, by repeatedly drawing the cleaning solution through the
pipelines to a solution tank located at the terminal end of the line, and
reversing the direction of flow to return the solution by gravity to the
original reservoir in the milk room., by using a device which will, on each
cycle, assure emptying of the solution into the original reservoir.
E. HEALT11 OFFICER.
The term Health Officer shall mean the Health Officer of the City
of Little Rock, Arkansas or his authorized representative.
SECTION 2. PERMIT.
No producer shall install or use a C.I.P. pipeline system on a
dairy farm, for which a Little Rock Health Department permit is required, until
plans have been submitted to, and approved by, the Little Rock Health Department.

set of plans. The schedule shall indicate the detergent to be used and the
manufacturerts name and recommendation with respect to concentration, period
of circulation and temperatures to be maintained. In all cases the detergent
shall be compatible with the water supply.
If the plans and schedules of cleaning are in compliance, authori-
zation for installation may be granted; however, final approval shall be based
upon a physical inspection, and if approved for a permit, thereafter no
modification of, or additions thereto, shall be made without approval of the
Health Officer. The permit shall be conspicuously posted in the milk room.
SECTION 3• MATERIAL AND FACILITIES..
Item 1. -All milk contact surfaces, solution lines, wash tanks,
fittings, vacuum lines from the milk receiver to the moisture trap, shall be
constructed of 18.8 stainless steel with 180 grit finish or its equivalent,
heat resistant glass, or equally corrosion resistant material which is,,non -toxic
and non - absorbent. Gaskets shall be non- absorbent, non - toxic, self- centering
and flush on the inside when fully compressed.
Item 2.--An adequate supply of hot and cold water under pressure
shall be provided.
Item 3, - -The minimum capa:qity of the hot water tank shall be 30
gallons if gas heated, and 40 gallons if electrically heated, Water heating
temperatures shall be maintained during the rinsing and washing operation, if
recommended by the manufacturer.

Item 4. --A mixing valve for hot and cold water shall be provided.
Item 5.-- Suitable brushes for cleaning and suitable tools for
disassembling pipelines and fittings shall be provided.
Item 6.--An approved thermometer must be provided for determining
the termperatures of the cleaning solutions.
SECTION 4. INS TALUTION .
Item 1. --The entire pipeline system, including return lines, shall
be installed so as to be completer self draining, and to avoid excess of
agitation to minimize the possibility of rancidity. Risers are prohibited. All
milk lines shall have a positive slope toward the milk receiver of not less than
1 inch per 10 feet and shall be firmly anchored in place in such manner as to
prevent electrorsis. The pipeline system shall be so located as to require the
shortest possible milk hose, which shall be free of loops and depressions, and
connected to the pipeline system above the median line.
Item 2.--All "'0 " ring and slip joint fittings must be taken down
for cleaning after each milking.
Item 3. - -Tbe vacuum line from the milk receiver shall have a
positive drain to a moisture trap, and the vacuum line from the moisture trap
shall not extend in a vertical position above the milk receiver more than 6 inches
including the elbow. This section shall be demountable for inspection and there
shall be no other physical connection between the vacuum lime and the milk pipeline.
Item 4. - -No connecting valves are permitted between the milk lines
and the solution lines, and the entire milk line and solution line shall be of the
same diameter.
Item 5.- -The wash solution tank shall be of stainless steel and
have a minimum capacity of twice the volume of water required to fill the entire
pipeline and shall be located in the milk room.
Item 6.- No physical connection is permitted between the vacuum line
and the milk line other than the moistwe trap and milk releaser.
Item 7.— Ends of milk lines, milk valves, stall cocks on vacuum lines
and other openings subject to contamination shall be capped.
Item 8.— All equipment and parts thereof cleaned -in -place shall be
of such design, construction and installation as to permit thorough cleaning, and
easily dismantled for detailed inspection, and self draining*

Item 9.-A chemical test of the water shall be made to determine
the compatibility with the detergent, and a copy of the water analysis, together
with the detergent to be used, as well as the washing instructions, shall be
posted in the milk roars. The installer shall mark the wash vat to indic4te the
proper level of washing and rinsing solutions to be used.
Item 10.-- Regardless of the C.I.P. method used, the pump shall be
of sufficient size to cause enough turbulence and surge to insure adequate clean-
ing, and in case the pressure method is used, it shall deliver not less than
25 gallons of solution per minute at the discharge end of 12 inch lines. In the
vacuum - gravity system there shall be a cut -off valve located in the line to
prohibit milk solids from entering the reservoir portion of the cleaning system,
or the line shall be broken and capped during the milking operation, The clean-
ing cycle shall be of such duration as to completely drain the line between each
pulsation.
SECTION 5• C=NING PROCEDURES.
