(d) Any milk in the external piping system that exceeds forty-five degrees Fahrenheit is discarded.

(e) Adequate facilities must be provided at all receiving stations for the proper cleaning and sanitizing of tankers including the external lines and valves.

(2) All external valves on a tanker must be provided with a means of protection against dust, dirt, and road debris.

(a) Outlet valves must be protected by dust tight covers that will comply with 3A standard 05-14.

(b) Inlet valves and valves with attached hoses must be protected by a relatively dust tight cover. This cover may be:

(i) Stainless steel with an opening for the connection of hoses that is sealed with a flexible material that will prevent the entrance of dust, dirt, or road debris.

(ii) A flexible mounting made of rubber or other approved material that is close fitting, smooth, impervious, and easily removable for cleaning.

(iii) Any other cover for which plans have been submitted to and approved by the director.

(c) All valves not connected to hoses must have a sanitary cap and an approved dust cover on them.

(3) Markings on each truck or trailer must be sufficient to identify the owner of the truck or trailer.

(4) Cleaning and bactericidal treatment of all product contact surfaces including valves, hoses, covers, connections, appurtenances, pumps, and pump compartment of each tanker, when used, must be accomplished at least once every twenty-four hours after first use. If the tanker is not used for hauling milk for seventy-two hours after cleaning and sanitizing it must be sanitized again before it may be used for hauling milk. After sanitization each tanker must be tagged to show the date washed, place washed, and initials or signature of the person who washed the tanker. This wash tag must not be removed until the tanker is rewashed. It shall be the responsibility of the bulk milk hauler to ensure that the wash tag is present and that the tank is in fact clean prior to commencing his route.

(5) Bulk milk tankers must meet the requirements under chapter 15.130 RCW and the rules adopted thereunder for transportation of food.

(1) All new farm bulk tank installations must include a recording thermometer and an automatic interval timer. Installation of a used milk tank will be regarded as a new installation.

(2) The installation and operation of recording thermometers and interval timers shall be the responsibility of the holder of the Grade A producer permit.

(3) Recording devices must not be attached to a farm tank. Recording devices may be suspended on metal brackets from the ceiling, firmly attached to the inside wall of the milk room, or at any other location acceptable to the department. The recording device must be mounted no more than six feet from the floor or be otherwise accessible from the floor without the necessity of climbing.

(4) The sensor bulb or device must be located so as to record the temperature of the milk in the tank before the milk reaches twenty percent of the tank volume. A capillary system containing toxic gas or liquids must not be used in a bare bulb sensor device.

(5) The recorder and chart must be capable at a minimum of recording from thirty-two degrees to one hundred eighty degrees F, or above, and must be accurate within plus or minus two degrees F.

(6) The case of the recording device must be moisture-proof under operating conditions in the milk house or milk room.

(7) The recording chart must make at a minimum one revolution every seven days. A strip chart must not be used.

(8) The recording clock must be electrically operated. The recorder pen must be set to the actual time.

(2) In making a milk pick-up, the licensed grader and sampler must:

(a) Remove the chart from the recorder before the chart has lapsed;

(b) Mark the date and time of pick-up;

(c) Sign the chart;

(d) Date and install a new chart, if necessary;

(e) File the completed charts under protected conditions, provided for by the producer, unless they are taken to the purchaser's premises for his review.

(f) If the charts are taken from the dairy farm, they must be returned within ten days from the date they were taken: Provided, That subject to the approval of its members and the department, a pooling agent, processing plant, receiving plant or regular place of business may file the recording thermometer charts at its place of business.

(g) The official milk temperature must be taken with an accurate, properly calibrated thermometer.

(3) The temperature recording charts may be used for more than one pick-up: Provided, That all the pick-ups occur within the maximum time interval of the chart. When the chart is used for more than one pick-up, the licensed grader and sampler must identify each lot of milk with the date, time of pick-up and his/her signature.

(4) Before removing milk from a farm bulk tank, the licensed grader and sampler must check the recording chart. If the licensed grader and sampler finds milk temperature variations extending beyond the legal limits, he/she must immediately notify the producer, or in the absence of the producer, an employee, and the producer's marketing agent. The licensed grader and sampler must sign the chart noting the date, time, stick reading and indicate that a temperature infraction has occurred. The producer's marketing agent must notify the department of agriculture of temperature standard violations detected through the official milk quality testing program. Temperature standard violations reported to the department will become part of the producer's official record.

(5) Except as otherwise provided in subsection (2) of this section, recorder charts must be held at the dairy farm for ninety days and be made available to the director.
