ATCP 70.20(3)(b)(b) Water reclaimed from a heat exchanger process, from a compressor cooling unit, from the condensation of food products, or from other food processing plant systems or processes may be used as operations water with department approval if the water complies with par. (a) or if all of the following apply:

ATCP 70.20(3)(b)1.1. The water is reclaimed by means of evaporation, reverse osmosis, ultra-filtration, a heat exchanger, or another method approved by the department.

ATCP 70.20(3)(b)2.2. The water, if reclaimed from the condensation of food products, has a standard turbidity of less than 5 units, an electrical conductivity maintained in correlation with organic content of less than 12 mg. per liter, or an organic content of less than 12 mg. per liter, as measured by the chemical oxygen demand or permanganate-consumed test as specified in Standard Methods for the Examination of Water and Wastewater, twenty-first edition (2005), published by the American Public Health Association, the American Water Works Association, and the Water Environment Federation. The operator shall use an automatic fail-safe monitoring device to identify, and automatically divert to a waste water system, any reclaimed water that fails to comply with this subdivision.

ATCP 70.20 NoteNote: Copies of the Standard Methods for the Examination of Water and Wastewater, twenty-first edition (2005), published by the American Public Health Association (APHA), the American Water Works Association, and the Water Environment Federation, are on file with the department and the legislative reference bureau. Copies may be obtained by contacting the “APHA Bookstore” at www.apha.org/publications/bookstore/.

ATCP 70.20(3)(b)3.3. The reclaimed water is of satisfactory organoleptic quality and has no off-odors, off-flavors, or slime. The operator shall sample and organoleptically test reclaimed water at weekly intervals.

ATCP 70.20(3)(b)4.4. Chemical treatment of the reclaimed water, if any, complies with sub. (4).

ATCP 70.20(3)(b)5.5. The reclaimed water is stored in a properly constructed tank. The tank shall be constructed of a material that will not contaminate the water and can be easily cleaned.

ATCP 70.20(3)(b)6.6. There are no cross-connections between reclaimed water lines and any public or private water system, except for lines with backflow preventers that meet the requirements of chs. SPS 382 and 384.

ATCP 70.20(3)(b)7.7. The reclaimed water, if held for more than 24 hours, is at all times held at a temperature of at least 145°F (63° C) or is chemically treated under sub. (4) to suppress bacterial growth.

ATCP 70.20(3)(b)8.8. Distribution lines and hose stations used to distribute the reclaimed water are clearly identified as “limited-use reclaimed water.”

ATCP 70.20(3)(b)9.9. The operator posts clear instructions for the use of the reclaimed water. The operator shall post the instructions so that they will be seen and understood by persons using the reclaimed water. The instructions shall disclose the limited purposes for which the reclaimed water may be used.

ATCP 70.20(3)(b)10.10. Water lines distributing the reclaimed water are not permanently connected to food product vessels. If a water line is temporarily connected to a food product vessel, there shall be an atmospheric break and automatic controls to prevent the reclaimed water from contacting food products.

ATCP 70.20(3)(c)(c) Water reclaimed from food processing operations may be used for cleaning or other purposes but may not be used for any purpose involving contact with food or food contact surfaces except as provided in par. (a) or (b).

ATCP 70.20(4)(a)(a) An operator may not use any chemical to suppress bacterial growth in water, or to prevent off-tastes or odors in water, unless that chemical is approved for that purpose by the U.S. environmental protection agency. Neither the chemical as applied, nor any compound produced by the chemical application, may adulterate food in the food processing plant in which it was used.

ATCP 70.20(4)(b)(b) An operator shall apply chemicals, under par. (a), according to label directions using an automatic proportioning device. Treated water shall be held for the period of time specified on the chemical label before it is used as ingredient water or operations water. An operator shall conduct a daily testing program for any chemical added to water, to ensure that the chemical concentration does not adulterate food.

ATCP 70.20(5)(a)(a) If re-circulated water used in a cooler or heat exchanger may come in contact with any food product or food contact surface, the re-circulated water shall be all of the following:

ATCP 70.20(5)(a)1.1. Obtained from a source that complies with chs. NR 811 or 812, as applicable.

ATCP 70.20(5)(a)2.2. Bacteriologically safe.

ATCP 70.20(5)(a)3.3. Protected from contamination.

ATCP 70.20(5)(a)4.4. Tested by the operator for compliance with subd. 2. at 6 month intervals.

ATCP 70.20(5)(b)(b) If a re-circulating water system, under par. (a), becomes contaminated, that system may not be used until it is properly treated and analytical results indicate that the contamination has been eliminated.

ATCP 70.20(6)(a)(a) Water transported to a food processing plant in a bulk tanker or bulk container, for use as an ingredient or in other plant operations, shall be potable and shall be obtained from a source that complies with ch. NR 811 or 812.

ATCP 70.20(6)(b)(b) Whenever potable water or another potable liquid is transported to or from a food processing plant in a bulk tanker or bulk container, it shall be loaded, transported, and unloaded in a sanitary manner that prevents contamination. The bulk tanker or bulk container shall be thoroughly cleaned and sanitized before being filled. Suitable pumps, hoses, and fittings shall be used to transfer potable water and potable liquids to and from bulk tankers, and bulk containers, and shall be cleaned and sanitized prior to use.

ATCP 70.20(6)(c)(c) Whenever potable water or another potable liquid is transported to or from a food processing plant in a bulk tanker or bulk container, the bulk tanker or bulk container and each of its fittings and equipment shall meet all of the following requirements:
