(a) A separate milkhouse of sufficient size is provided in which the cooling, handling and storing of milk, and the washing, sanitizing and storing of milk containers and utensils shall be conducted; except as provided for in section 2.19 of this Part (Item 12r).

(b) The floors of all milkhouses are constructed of good quality concrete (float finish permissible), or equally impervious tile, or brick laid closely with impervious material, or metal surfacing with impervious joints, or other material the equivalent of concrete and maintained free of breaks, depressions and surface peelings.

(c) The floor slopes to drain so that there are no pools of standing water. The joints between the floor and the walls shall be watertight.

(d) The liquid wastes are disposed of in a sanitary manner; all floor drains are accessible and are trapped if connected to a sanitary sewer.

(e) Walls and ceilings are constructed of smooth-dressed lumber or similar material, well-painted with a light-colored washable paint, and are in good repair. Surfaces and joints shall be tight and smooth. Sheet metal, tile, cement block, brick, concrete, cement plaster or similar materials of light color may be used; the surfaces and joints shall be smooth.

(f) A minimum of 20 foot-candles of light is provided at all working areas from natural and/or artificial light for milkhouse operations.

(g) Windows and solid doors are closed during dusty weather.

(h) The milkhouse is adequately ventilated to minimize odors and condensation on floors, walls, ceilings and clean utensils.

(i) Vents, if installed, and lighting fixtures are installed in a manner to preclude the contamination of bulk milk tanks or clean utensil storage areas.

(j) The milkhouse is used for no other purpose than milkhouse operations.

(k) There is no direct opening into any barn, stable or room used for domestic purposes; except that an opening between the milkhouse and milking barn, stable or parlor is permitted when a tight-fitting self-closing solid door(s) hinged to be single or double acting is provided.

(l) A vestibule, if used, complies with the applicable milkhouse construction requirements.

(m) The transfer of milk from a bulk-holding/cooling tank to a transport tank is through a hose port located in the milkhouse wall. The port shall be fitted with a tight door, which shall be in good repair. It shall be kept closed except when the port is in use. An easily cleanable surface shall be constructed under the hose port, adjacent to the outside wall, sufficiently large to protect the milk hose from contamination. Such surface shall be at least 36 inches wide and shall extend from the working area at the rear of the bulk tank truck to the hose port.

(n) Water under pressure is piped into the milkhouse; provided, however, that a dairy farm that produces prepasteurized milk for non-Grade A use shall have water available to the milkhouse.

(o) Each milkhouse is provided with facilities for heating water in sufficient quantity and to such temperatures for the effective cleaning of all equipment and utensils; provided, however, that a dairy farm that produces prepasteurized milk for non-Grade A use shall have water available to the milkhouse in sufficient quantities and heated to sufficient temperatures to properly clean all equipment and utensils.

(p) The milkhouse is equipped with a wash-and-rinse vat having at least two compartments. Each compartment must be of sufficient size to accommodate the largest utensil or container used. The cleaning-in-place vat for milk pipelines and milk machines may be accepted as one part of the two-compartment vat; provided, that the cleaning-in-place station rack in or on the vat and the milking machine inflations and appurtenances are completely removed from the vat during the washing, rinsing and/or sanitizing of other utensils and equipment.

(q) A suitable shelter is provided for a transportation truck used for cooling and storing milk. Such shelter shall be adjacent to, but not a part of, the milkroom and shall comply with the requirements of the milkroom with respect to construction, light, drainage, insect and rodent control, and general maintenance.
