Current through Register 2024 Notice Reg. No. 28, July 12, 2024
All pipeline milking machine installations must comply with
					 the following conditions and must have a satisfactory circulating system for
					 washing and sterilizing which has been approved by the director; or such system
					 must be disassembled, washed and sterilized after each time used, except that
					 deviations from the minimum requirements and specifications may be made after
					 approval in writing by the director:
(a) All equipment having any surface in
				  contact with the milk and all solution lines, wash tanks, fittings, vacuum
				  lines from air separator to moisture trap shall be constructed of stainless
				  steel, nickel alloy, heat-resistant glass or equally corrosion-resistant
				  material that is nontoxic and nonabsorbent.
(b) All milk contact surfaces, whether a
				  ground or bright annealed finish, shall be finished to an equivalent of not
				  less than 120-grit finish, properly applied, and shall be free from pits,
				  cracks, and crevices.
(c) The milk
				  pipeline system shall be installed in a manner to permit being disassembled for
				  inspection.
(d) Sanitary milk pipes
				  which are not washed in place shall be no longer than the washing and
				  sterilizing facilities will accommodate.
(e) The entire milk line shall be installed
				  so as to have a positive slope and be completely drained. It must be supported
				  by permanent hangers or other means to prevent sagging and to maintain
				  alignment.
(f) The vacuum line from
				  the air separator to the moisture trap must have at least one-half inch
				  downward slope in the first foot.
(g) The vacuum line from the air separator
				  shall not extend in a vertical position above the separator more than six
				  inches including the elbow.
(h) The
				  entire milk pipeline and solution pipeline must be of the same inside diameter
				  when a pressure circulating system of clean-up is used.
When a vacuum system of circulation is used, the inside
					 diameter of the pipelines and appurtenances may vary in size if sufficient
					 turbulence is created during circulation of the solutions to contact and clean
					 and sanitize all surfaces. Injection of pulses of air is one method of
					 increasing turbulence.
(i)
				  Solution lines must be disconnected from milk pipelines during milking unless
				  (1) the solution or wash line is disconnected from any solution or wash tank
				  for the entire milking, and (2) all solution or wash lines are drained before
				  milking begins.
Vacuum lines may be connected to milk pipelines only when
					 areas not properly cleaned and sanitized are effectively isolated from milk
					 contact areas.
Water lines must be disconnected from milk lines during
					 milking.
(j) All milk pumps
				  and attachments shall be protected from possible contamination. If legs are
				  used, they shall be smooth with rounded ends and no exposed threads. Legs made
				  of hollow stock shall be sealed. On pumps with legs designed to be fixed to the
				  floor, the minimum clearance between the lowest part of the base and the floor
				  shall be four inches. Readily portable pumps not permanently attached may have
				  leg heights of two inches. (Readily portable pumps are defined as those having
				  a base area of not more than one square foot, or, in the case of motor-mounted
				  pumps, an area encompassed by the legs that does not exceed one square foot.)
				  Bases when used shall be constructed without ribs or flanges and shall have a
				  smooth top and bottom surface. Pumps which because of their size and type
				  cannot be mounted on legs, shall be mounted on a base designed for grouting and
				  sealing. All milk pumps and attachments must be a sufficient distance from
				  walls to permit proper cleaning.
(k) (Section
				  33481 Food and Agricultural Code.)
				  When a dump tank is used in the milking barn, it must be located in accordance
				  with Section
				  481.5 of the Administrative Code
				  and must be kept covered except when milk is being poured. Milk on test days
				  and strippings shall enter the milk pipeline through the dump tank. If dump
				  tank is located next to the barn wall between milkhouse and barn, the barn wall
				  must be at least six feet high.
(l)
				  The Cleaned-in-Place (CIP) wash tank shall be located in the milkhouse; any
				  other location must be approved by the director.
(m) A thermometer must be installed on the
				  discharge end of the circulating system and the washing solution temperature
				  during circulation cleaning maintained at 115°F. or above.
(n) Milk tanks, dump tanks, releasers, when
				  located in passageway shall be constructed so as to protect milk from flies,
				  dust and contamination.
(o) Ends of
				  milk lines, stall cocks and other pipeline openings subject to contamination
				  shall be capped or otherwise protected.
(p) Sight glasses shall not be permitted on
				  milk pipelines when such milk pipelines are cleaned by circulation.
(q) The circulating pump shall be of a size
				  sufficient to fill the pipelines and cause enough turbulence to insure adequate
				  cleaning and shall deliver not less than 25 gallons of solution per minute at
				  discharge end of 1 1/2 -inch lines and corresponding volumes for other size
				  pipes when pressure system of circulation is used.
(r) Air line from moisture trap to milk
				  releaser or air separator shall be washed and sterilized after each time
				  used.
(s) The outside of milk
				  pipelines and equipment shall be kept clean.
(t) Vacuum pumps, motors, or any machinery
				  that may emit oil, fumes, grease, odors, or any objectionable material shall
				  not be located over or near milk equipment.
(u) Milk pipelines connected by the so-called
				  slip joint method, with or without an "O" ring gasket must be disassembled for
				  cleaning after each use.
(v)
				  Gaskets, when used, must be made of a low-absorbent material which is smooth
				  and nontoxic. Paper and fiberlike gaskets are not acceptable. Gaskets must be
				  self-positioning and of such design to form a substantially flush interior
				  joint.
(w) Openings for inspection
				  must be provided on welded metal pipeline installations in order to provide
				  access to determine the cleaning efficiency of Cleaned-in-Place
				  systems.
(x) Milk pumps, pipelines,
				  and air separators which are a part of an enclosed pipeline system may be
				  installed in the passageway or an area approved by the Director, in the milking
				  barn, provided, that all of the equipment is protected from contamination at
				  all times. Plate type or internal tubular coolers may be installed in the
				  milkhouse or passageway.
(y)
				  Milking machine claws and milker units may be cleaned in place in the milking
				  barn, provided, they are effectively cleaned, sanitized, and drained by the CIP
				  system, and subsequently protected from dust, flies, contact with animals, or
				  other contamination until the next milking is begun.
Whenever units are dismantled for hand cleaning, such
					 cleaning shall be done in the milkhouse.
