ATCP 65.24(9)(b) (b) Except as provided in par. (c), reclaimed water may not be used for any purpose requiring potable water unless all the following apply:

ATCP 65.24(9)(b)1. 1. The department pre-inspects and pre-approves the reclamation system.

ATCP 65.24(9)(b)2. 2. The reclaimed water contains less than 1 coliform bacterium per 100 ml. of water.

ATCP 65.24(9)(b)4. 4. The organic content of the water is less than 12 mg. per liter as measured by the chemical oxygen demand or permanganate-consumed test, or the water has a standard turbidity of less than 5 units. The dairy plant operator shall use an automatic fail-safe monitoring device to identify, and automatically divert to a waste water system, any water reclaimed from the condensation of dairy products if that water fails to meet this standard.

ATCP 65.24(9)(b)5. 5. The reclaimed water is of satisfactory organoleptic quality. The dairy plant operator shall sample and organoleptically test reclaimed water at weekly intervals.

ATCP 65.24(9)(b)6. 6. Any chemicals used to suppress bacterial growth, tastes, or odors in the reclaimed water are registered for that use with the U.S. environmental protection agency. The dairy plant operator who uses any chemical to suppress bacterial growth, tastes, or odors shall comply with the chemical label instructions. An added chemical may not contain any substance that may contaminate dairy products or limit the use of reclaimed water. An automatic proportioning device shall add the chemicals to the water before the water enters the storage tank. The dairy plant operator shall test reclaimed water at least daily to verify that each added chemical is present at an approved level.

ATCP 65.24(9)(b)7. 7. The reclaimed water is stored in a properly constructed tank. The tank shall be constructed of a material that can be easily cleaned and sanitized and will not contaminate the water.

ATCP 65.24(9)(b)8. 8. The dairy plant operator or, in the case of a grade A dairy plant, the division tests the reclaimed water for compliance with microbiological and organic content standards at least semi-annually. The operator shall test the reclaimed water for 14 working days after the department approves the reclamation system under subd. 1., and for at least 7 working days after any repairs or alterations to the system.

ATCP 65.24(9)(b)9. 9. There are no cross-connections between reclaimed water lines and any public or private water system.

ATCP 65.24(9)(b)10. 10. Reclaimed water from membrane processing of unpasteurized milk or unpasteurized dairy products shall be heat-treated for a time and at a temperature providing at least the same lethality against microorganisms as milk pasteurization.

ATCP 65.24(9)(c) (c) Reclaimed water may be used for the limited purposes of producing culinary steam, pre-rinsing food contact surfaces of equipment or utensils, or preparing cleaning solutions if all the following apply:

ATCP 65.24(9)(c)1. 1. The reclaimed water meets all conditions under par. (b) 1., 2., 4. to 7., and 9.

ATCP 65.24(9)(c)2. 2. The reclaimed water is used only on the day that it is reclaimed, except that reclaimed water may be stored for later use if it is automatically maintained at a temperature of not less than 145° F. (63° C.), or is chemically treated to suppress bacterial propagation. Chemical treatments shall comply with par. (b) 6.

ATCP 65.24(9)(c)3. 3. Distribution lines and hose stations used to distribute the reclaimed water are clearly identified as “limited-use reclaimed water.”

ATCP 65.24(9)(c)4. 4. The dairy plant operator posts clear instructions for the use of the reclaimed water. The operator shall post the instructions so that they will be seen by persons using the reclaimed water, and the instructions shall be written in such a way that they will be understood by the persons using the reclaimed water. The instructions shall disclose the limited purposes for which the reclaimed water may be used.

ATCP 65.24(9)(c)5. 5. Water lines distributing the reclaimed water are not permanently connected to dairy product vessels. If a water line is temporarily connected to a dairy product vessel, there shall be an atmospheric break and automatic controls to prevent the reclaimed water from contacting dairy products.

ATCP 65.24(9)(d) (d) Reclaimed water that does not qualify for use, under par. (b) or (c), may only be used as boiler feedwater.

ATCP 65.24(10) (10) Plumbing system; disposal of sewage and liquid waste.

ATCP 65.24(10)(a) (a) All dairy plant plumbing, plumbing fixtures, and equipment shall comply with state and local plumbing codes and shall be designed, installed, and maintained to prevent backflow, backsiphonage, and cross-connections.

ATCP 65.24(10)(b) (b) Sewage and liquid waste from a dairy plant shall be removed in a sanitary manner, in compliance with applicable state and local regulations.

ATCP 65.24 Note Note: Plumbing and plumbing fixtures must comply with applicable rules of the Wisconsin department of safety and professional services under chs. SPS 382 to 386.

ATCP 65.24(11) (11) Cleaning facilities.

ATCP 65.24(11)(a) (a) If equipment or utensils in a dairy plant are cleaned or sanitized manually, the dairy plant shall be equipped with wash and rinse sinks that are suitable for all manual cleaning and sanitizing operations. Sinks shall be conveniently located and adequate in number, and shall comply with all of the following requirements:

If a dairy plant is also engaged in food processing as defined under s. 97.29 (2) (b), Stats., every sink installed in a food processing area after December 1, 1994 shall have at least 3 compartments for washing, rinsing, and sanitizing equipment and utensils unless the dairy plant operator uses an alternative method for sanitizing equipment and utensils that the division has approved in writing.

ATCP 65.24(11)(a)3. 3. Every sink compartment shall be large enough so that the largest item cleaned or sanitized in the sink can be halfway immersed in the sink. Every sink compartment shall be served by hot and cold running water and shall be cleaned prior to each use.
