(1) BULK TANK
				  LOCATION. If a bulk tank is used to receive, cool, or store milk on a dairy
				  farm, the bulk tank shall be installed in the milkhouse. A bulk tank may be
				  installed so that a portion of the bulk tank protrudes through the wall of a
				  milkhouse, provided that all bulk tank openings are located inside the
				  milkhouse. Agitator seals, other than weatherproof agitator seals approved in
				  writing by the division, shall be located inside the milkhouse. Clearance of at
				  least 24 inches on the top and milk-outlet side shall be maintained on a bulk
				  tank not protruding through the milkhouse wall to permit effective cleaning,
				  sanitizing, and maintenance of the bulk tank. No bulk tank opening may be
				  located directly under a ventilator. No bulk tank may be located directly over
				  a floor drain.
(2) BULK TANK
				  CONSTRUCTION.
(a) The lining and milk contact
				  surfaces of a bulk tank shall be constructed of stainless steel or other
				  materials that are equally smooth, nontoxic, stable, non-absorbent, corrosion
				  resistant, and capable of withstanding cleaning and sanitizing treatment. Milk
				  contact surfaces shall be readily accessible for inspection.
(b) A bulk tank shall be self-draining.
				  Openings shall be equipped with self-draining covers. Openings and covers shall
				  be constructed and installed to prevent drainage into milk or onto milk contact
				  surfaces.
(c) A bulk tank shall be
				  equipped with all of the following:
1. An
				  indicating thermometer that has a range of at least 32° F. to 80°
				  F.
2. A temperature recording
				  device approved by the division, if the bulk tank was manufactured after
				  January 1, 2000. The temperature recording device shall comply with sub.
				  (3).
(d) A bulk tank
				  with a capacity of less than 1,500 gallons shall be equipped with a mechanical
				  agitator that will ensure homogeneity of all milk contained in the bulk tank
				  within 5 minutes after the agitator begins operating. A bulk tank with a
				  capacity of 1,500 gallons or more shall be equipped with an agitator that will
				  ensure homogeneity of all milk contained in the bulk tank within 10 minutes
				  after the agitator begins operating.
(e) A C-I-P bulk tank shall be designed and
				  constructed so that cleaning, rinsing, and sanitizing solutions cannot enter
				  the bulk tank while it contains milk.
