13.Use of flexible lines between bottom fill bulk tanks for functional purposes
is allowed, however these flexible hoses must meet the following
requirements:

 Must be readily drainable and as short as practical.
 Have permanent sanitary fittings
 Must be properly supported to maintain uniform slope and alignment.
 The transfer hose must be a part of the CIP system.

BULK MILK TANKER REQUIREMENTS

1. All bulk milk tankers must meet the construction requirements of Items 10p
and 11p of the PMO. Specific construction and fabrication guidelines may
be found in the 3A Sanitary Standards, Number 05-13.

2. Vehicles must be kept clean, inside and out.

3. Inspectors must guard against back hauling practices which may
contaminate the milk supply. The hauling of any non-food or toxic
substances in milk tankers is strictly prohibited and should be considered a
violation of the PMO.

o
4. Tankers shall be insulated sufficiently to permit no more that a 2 F
temperature rise in an 18 hour period measured with the tanker filled with
water. This determination shall be made when the average temperature
o
differential between the water and the atmospheric temperature is 30 F.

5. Tanker manholes shall be located so that the distance from either end of
the tank shall not exceed 18 feet, 6 inches. (This does not apply to tankers
with permanently installed mechanical cleaning devices.)

6. The upper edge of the manhole cover shall be not less than 3/8 inch higher
than the surrounding area and if an exterior flange is incorporated, it shall
slope and drain away from the opening. Provided, that adequate drain
holes may be located in the dam so as to prevent the flooding of the
dam up to the minimum level of 3/8 inch. Judgment must be used in
the evaluation of this item so that the dam area must protect the tank
manhole entrance while the tanker is traveling or parked on inclines or
slopes which may flood the manhole entrance.
