Ch. ATCP 51 Note
Note: This chapter is adopted under authority of ss.
93.07 (1) and
93.90 (2),
Stats. This chapter interprets Wisconsin's livestock facility siting law, s.
93.90, Stats. According to the livestock facility siting law, a county, town, city or village (“political subdivision") may not prohibit or disapprove a new or expanded livestock facility of any size unless one of the following applies:
Ch. ATCP 51 Note
The site is located in a zoning district that is not an agricultural zoning district.
Ch. ATCP 51 Note
The site is located in an agricultural zoning district where the livestock facility is prohibited. A prohibition, if any, must be clearly justified on the basis of public health or safety. The livestock facility siting law limits exclusionary zoning based solely on livestock facility size.
Ch. ATCP 51 Note
The proposed livestock facility violates a valid local ordinance adopted under certain state laws related to shoreland zoning, floodplain zoning, construction site erosion control or stormwater management.
Ch. ATCP 51 Note
The proposed livestock facility violates a local building, electrical or plumbing code that is consistent with the state building, electrical or plumbing code for that type of facility.
Ch. ATCP 51 Note
The proposed livestock facility will have 500 or more “animal units" (or will exceed a lower permit threshold incorporated in a local zoning ordinance prior to July 19, 2003), and the proposed facility violates one of the following:
Ch. ATCP 51 Note
• A state livestock facility siting standard adopted by the department under this chapter.
Ch. ATCP 51 Note
• A more stringent local ordinance standard enacted prior to the siting application. The more stringent local standard must be based on reasonable and scientifically defensible findings of fact, adopted by the local jurisdiction, which clearly show that the standard is necessary to protect public health or safety.
Ch. ATCP 51 Note
Some, but not all, political subdivisions require local approval of new or expanded livestock facilities. The livestock facility siting law does not require local approval. But if local approval is required, the political subdivision must grant or deny approval based on this chapter. A political subdivision may not consider other siting criteria, or apply standards that differ from this chapter, except as provided in the livestock facility siting law or this chapter.
Ch. ATCP 51 Note
The department must review the livestock facility siting standards under this chapter at least once every 4 years (
see s.
93.90 (2) (c), Stats.). The department will review the standards at least annually during the first 4 years of rule implementation. The department will track local siting applications and decisions (
see s.
ATCP 51.34 (5)), and will review that information at least monthly during the first year of rule implementation.
Ch. ATCP 51 Note
The livestock facility siting law includes the following statements of legislative intent:
Ch. ATCP 51 Note
“This [law] is an enactment of statewide concern for the purpose of providing uniform regulation of livestock facilities."
Ch. ATCP 51 Note
“…[T]he department shall consider whether
[livestock facility siting standards] are all of the following:
Ch. ATCP 51 Note
• Protective of public health or safety.
Ch. ATCP 51 Note
• Practical and workable.
Ch. ATCP 51 Note
• Cost-effective.
Ch. ATCP 51 Note
• Objective.
Ch. ATCP 51 Note
• Based on available scientific evidence that has been subjected to peer review.
Ch. ATCP 51 Note
• Designed to promote the growth and viability of animal agriculture in this state.
Ch. ATCP 51 Note
• Designed to balance the economic viability of farm operations with protecting natural resources and other community interests.
Ch. ATCP 51 Note
• Usable by officials of political subdivisions."

ATCP 51.01 Definitions. In this chapter:
ATCP 51.01(1)
(1) “Adjacent" means located on land parcels that touch each other, or on land parcels that are separated only by a river, stream, or transportation or utility right–of–way.
ATCP 51.01(2)
(2) “Affected neighbor" means, for purposes of the odor score calculation under
s. ATCP 51.14, a residence or high-use building located within 2,500 feet of any livestock structure at a proposed livestock facility. “Affected neighbor" does not include a residence or high-use building owned by any of the following:
ATCP 51.01(2)(b)
(b) A person who affirmatively agrees to have the residence or high-use building excluded from the odor score calculation under
s. ATCP 51.14.
ATCP 51.01 Note
Note: The odor score calculation under s.
ATCP 51.14 is based, in part, on the proximity and density of “affected neighbors."
See Appendix A, worksheet 2.
ATCP 51.01(3)
(3) “Animal lot" means a feedlot, barnyard or other outdoor facility where livestock are concentrated for feeding or other purposes. “Animal lot" does not include a pasture or winter grazing area. Two or more animal lots at the same livestock facility constitute a single animal lot, for purposes of this chapter, if runoff from the animal lots drains to the same treatment area under
s. ATCP 51.20 (2) or if runoff from the animal lot treatment areas converges or reaches the same surface water within 200 feet of any of those treatment areas.
ATCP 51.01 Note
Note: See s.
93.90 (1m) (a), Stats., and s.
ATCP 51.04. “Animal unit" equivalents, for different species and types of livestock, are shown in
Appendix A, worksheet 1 (animal units). The “animal unit" equivalents are based on s.
NR 243.03 (3) as it existed on April 27, 2004 (the date on which the livestock facility siting law,
2003 Wis. Act 235, was published).

ATCP 51.01 Note
Note: This chapter applies to local approvals of
new or expanded livestock facilities that will have 500 or more animal units (or will exceed a lower permit threshold incorporated in a local
zoning ordinance prior to July 19, 2003).
See s.
ATCP 51.02. Although this chapter covers all livestock structures in an “expanded livestock facility," existing structures are subject to less rigorous standards than new or expanded structures, and are completely exempt from certain requirements.
ATCP 51.01(14)
(14) “Expansion" means an increase in the largest number of animal units kept at a livestock facility on at least 90 days in any 12-month period. The acquisition of an existing livestock facility, by the operator of an adjacent livestock facility, does not constitute an “expansion" unless that operator increases the largest number of animal units kept at the combined livestock facilities on at least 90 days in any 12-month period.

(19) “Livestock facility" means a feedlot, dairy farm or other operation where livestock are or will be fed, confined, maintained or stabled for a total of 45 days or more in any 12–month period. A “livestock facility" includes all of the tax parcels of land on which the facility is located, but does not include a pasture or winter grazing area. Related livestock facilities are collectively treated as a single “livestock facility" for purposes of this chapter, except that an operator may elect to treat a separate species facility as a separate “livestock facility."
