NAC584.2171. Construction of milking barn, stable or parlor.

Every dairy farm shall have a milking barn, stable or parlor, located apart from any contaminating surroundings, in which the milking herd must be housed during milking operations. Any area used for milking must:

     1. Have a floor which is constructed of concrete or an equally impervious material, graded to drain liquids and coved with a 2-inch radius at the intersection of the floor and wall.

     2. Have walls and ceilings with a smooth finish that are light in color and impervious to water, soil and dust.

     3. Have natural or artificial light that is well distributed and suitable for milking, day or night. The working area must be illuminated by a minimum of 50 foot-candles of light and contain 4 square feet of window space for each 60 square feet of floor space unless the area is provided with adequate artificial light.

     4. Have sufficient air space and air circulation to prevent condensation and excessive odors. The minimum height of a ceiling in an area where hoofed mammals are milked must be 7 feet. Ventilation by means of forced air may be permitted upon approval by the Commission. Where ventilation by forced air is not in use, the area for milking must contain a minimum of 2 square feet of window for each milking stall. The area for milking must contain ceiling vents to give adequate ventilation.

     5. Contain dust-tight, covered boxes or bins, or other separate storage facilities for ground, chopped or concentrated feed.

     6. Contain adequate concrete ramps outside the doors providing entrance into and exit from the milk barn or parlor. These ramps and any holding corrals which are located adjacent to the milking barn or within 25 feet of it must have surfaces of concrete with curbs graded to provide drainage. The minimum height of curbs for holding corrals is 18 inches. The extent of the area which must have a surface of concrete will depend on the location and type of construction of the barn.

     7. Have provisions for the disposal of liquid wastes from the milkhouse, milk barn, stable or parlor and any adjoining ramps in a manner that prevents the pollution of any waterway or underground supply of water, the creation of odors and the breeding of flies. If the area contains a tank or tanks for liquid manure, the size of the pit which is necessary will be determined by the size of the operation and the length of time between pumpings.
