ATCP 51.02 Note
A political subdivision may not require local approval for new or expanded livestock facilities smaller than 500 animal units, except as specifically authorized by the livestock facility siting law and this chapter. A political subdivision may apply a lower size threshold adopted by ordinance prior to July 19, 2003
if that threshold is expressed as a specific number of animals or animal units. A local threshold expressed in locally-defined “animal units" may meet this test, because it effectively indicates a specific number of animals, even if the local ordinance definition of “animal units" differs from the definition in this chapter. However the local application and approval process must use the “animal units" definition in this chapter.
ATCP 51.02 Note
Local approvals under this chapter “run with the land."
See s.
ATCP 51.08. They normally continue to apply, despite changes in ownership, as long as subsequent owners do not violate the terms of the local approval. Some ordinances might require a
pro forma permit transfer with each transfer of ownership, but that transfer may not ordinarily limit the scope of approval.
ATCP 51.02 Note
A livestock operator is
not required to obtain local approval under this chapter for the construction, repair or improvement of livestock structures, unless the operator also adds “animal units" for which local approval is required (local building codes and manure storage ordinances may apply). However, a political subdivision may withdraw a local approval granted under this chapter if the livestock operator does any of the following (
see s.
ATCP 51.34 (4)):
ATCP 51.02 Note
• Without local authorization, alters the approved livestock facility in a way that materially violates the terms of the local approval.
ATCP 51.02 Note
• Alters the approved livestock facility so that the altered facility violates the standards in subch. II.

ATCP 51.04 Animal units. In this chapter, and in every local approval or application for local approval under this chapter, the number of animal units kept or authorized at a livestock facility means the maximum number of animal units that are or may be kept on at least 90 days in any 12-month period.
ATCP 51.04 Note
Note: This section accounts for normal day-to-day and seasonal variations in livestock numbers, as livestock are born, received, moved and marketed.
See s.
93.90 (3) (f), Stats.
ATCP 51.04 Note
Under this chapter, an applicant for local approval must specify the number of “animal units" for which the applicant seeks authorization. If the application is approved, the approval authorizes that number of “animal units." The authorized number is the maximum number of “animal units" that may be kept on 90 or more days in any 12-month period. A livestock operator may not exceed that authorized number without further local approval.
ATCP 51.04 Note
“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 51.06
ATCP 51.06 Local approval of existing livestock facilities. ATCP 51.06(1)(1)
General. Except as provided in
sub. (2), a local ordinance may not require local approval under this chapter for any of the following:
ATCP 51.06(1)(a)
(a) A livestock facility that existed before May 1, 2006 or before the effective date of the local approval requirement.
ATCP 51.06(1)(b)
(b) A livestock facility that the political subdivision has already approved. A prior approval for the construction of a livestock facility implies approval for the maximum number of animal units that the approved livestock facility was reasonably designed to house, except as otherwise clearly provided in the approval. Prior approval of a single livestock structure, such as a waste storage structure, does not constitute prior approval of an entire livestock facility.
ATCP 51.06 Note
Note: For example, if a political subdivision has already approved construction of a livestock facility that was reasonably designed to house up to 800 “animal units," that approval authorizes the operator to keep up to 800 “animal units" at that facility (even if the scope of approval is not explicitly stated in terms of “animal units").
ATCP 51.06(2)
(2) Expansions. A local ordinance may require local approval under this chapter for the expansion of a pre-existing or previously approved livestock facility under
sub. (1) if the number of animal units kept at the expanded livestock facility will exceed all of the following:
ATCP 51.06(2)(b)
(b) The maximum number previously approved or, if no maximum number was previously approved, a number that is 20% higher than the number kept on May 1, 2006 or on the effective date of the approval requirement, whichever date is later.
ATCP 51.06 Note
Note: Consider the following examples:
ATCP 51.06 Note
Example 1: Suppose that a local ordinance enacted after May 1, 2006 requires local approval for livestock facilities with 500 or more “animal units." “Local approval is
not required" for a livestock facility that already has 600 “animal units" on the local ordinance effective date, unless the facility expands to more than 720 “animal units." The number of “animal units" kept on the ordinance effective date means the largest number kept on at least 90 days in the 12 months prior to the ordinance effective date (
see s.
93.90 (3) (e), Stats.).
ATCP 51.06 Note
Example 2: Suppose that a local ordinance enacted prior to July 19, 2003 requires local approval of livestock facilities with 400 or more “animal units." An expansion from 200 “animal units" (existing facility) to 450 “animal units" (expanded facility) will require local approval, unless the political subdivision has already given its approval. If the political subdivision has already approved construction of a livestock facility that is designed to house up to 450 “animal units," the operator does not need further local approval unless the operator proposes to exceed 450 “animal units."

ATCP 51.08(1)(a)
(a) Runs with the land and remains in effect despite a change in ownership of the livestock facility or the land on which it is located.
ATCP 51.08 Note
Note: Some local ordinances may require a pro forma permit transfer with each transfer of ownership, but that transfer may not limit the scope of the prior approval.
ATCP 51.08(1)(b)
(b) Remains in effect regardless of the amount of time that elapses before the livestock operator exercises the authority granted by the approval, and regardless of whether the livestock operator exercises the full authority granted by the approval.
ATCP 51.08 Note
Note: For example, if a livestock operator gets local approval under this chapter to expand from 400 “animal units" (existing) to 900 “animal units", the livestock operator may implement the approved expansion over a period of time chosen by the livestock operator. The operator does not lose the approval merely because the operator implements the expansion in gradual stages, or fails to expand by the full amount authorized. However, the operator must at least begin the expansion within 2 years, or face possible loss of approval. See sub. (2).
ATCP 51.08(2)
(2) A political subdivision may withdraw a local approval granted under this chapter unless the livestock operator does all of the following within 2 years after a local approval is granted:
ATCP 51.08(2)(b)
(b) Begins construction on every new or expanded livestock housing structure, and every new or expanded waste storage structure, proposed in the application for local approval.
ATCP 51.08(3)
(3) If a local approval is appealed, the local approval is deemed to be granted for purposes of
sub. (2) when the appeal is concluded. Withdrawal of a local approval under
sub. (2) does not prevent a livestock operator from obtaining a new local approval under this chapter.
ATCP 51.08 Note
Note: A political subdivision should exercise sound judgment in deciding whether to withdraw a local approval under sub. (2). The political subdivision may consider extenuating circumstances, such as adverse weather conditions, that may affect an operator's ability to comply. A political subdivision should give the operator prior notice, and a reasonable opportunity to demonstrate compliance, before withdrawing a local approval.

ATCP 51.10 Livestock facility siting standards; general. ATCP 51.10(1)(1)
State standards apply. Except as provided in
sub. (2) or
(3), a political subdivision shall grant or deny local approvals covered by this chapter based on the standards in this subchapter.
ATCP 51.10(2)
(2) State standards incorporated in local ordinance. Beginning on November 1, 2006,
a political subdivision may not deny a local approval covered by this chapter unless the political subdivision incorporates by local ordinance the standards in this subchapter and the application requirements in subch.
III. A local ordinance may incorporate the standards and application requirements by reference, without reproducing them in full.
ATCP 51.10 Note
Note: The livestock facility siting law, s.
93.90, Stats., limits the reasons for which a political subdivision may deny local approval. For the first 6 months after the effective date of this chapter, from May 1, 2006 to November 1, 2006, a political subdivision may deny local approval based on standards in this chapter without incorporating those standards by local ordinance.
See sub. (1). Sub. (2) applies beginning on November 1, 2006.
ATCP 51.10(3)
(3) More stringent local standards. A political subdivision may not apply local standards that are more stringent than the standards in this subchapter unless all of the following apply:
ATCP 51.10(3)(a)
(a) The political subdivision is authorized to adopt the local standards under other applicable law.
ATCP 51.10(3)(b)
(b) The political subdivision enacted the standards by local ordinance, before the livestock facility operator filed the application for local approval.
ATCP 51.10(3)(c)
(c) The political subdivision enacted the standards based on reasonable and scientifically defensible findings of fact adopted by the political subdivision's governing authority.
ATCP 51.10(3)(d)
(d) The findings of fact under
par. (c) clearly show that the standards are needed to protect public health or safety.
ATCP 51.10(4)
(4) Ordinance provisions filed with department. Within 30 days after a political subdivision enacts an ordinance provision under
sub. (2) or
(3), the political subdivision shall file a copy of the ordinance provision with the department. Failure to file the ordinance provision with the department does not invalidate the ordinance provision. The political subdivision shall file the ordinance provision, by mail or e-mail, at the following applicable address:

ATCP 51.12 Livestock structures; location on property. ATCP 51.12(1)(1)
Property line and road setbacks; general. Livestock structures shall comply with local ordinance requirements related to setbacks from property lines and public roads, except that no local setback requirement may do any of the following:
ATCP 51.12(1)(a)
(a) Require a livestock structure to be set back more than 100 feet from any property line or public road right-of-way, except as provided in
sub. (2), if the livestock facility will have fewer than 1,000 animal units.
ATCP 51.12(1)(b)
(b) Require a livestock structure to be set back more than 200 feet from any property line, or more than 150 feet from any public road right-of-way, except as provided in
sub. (2), if the livestock facility will have 1,000 animal units or more.
ATCP 51.12(1)(c)
(c) Prevent the use of a livestock structure that was located within the setback area prior to the effective date of the setback requirement.
ATCP 51.12(1)(d)
(d) Prevent the expansion of a livestock structure that was located within the setback area prior to the effective date of the setback requirement, other than an expansion toward the property line or public road to which the local setback applies.
ATCP 51.12 Note
Note: Many local jurisdictions have established basic property line and road setback requirements by ordinance. Setbacks vary depending on local circumstances, and often reflect years of local experience. Subsection (1) honors local setback requirements, provided that the setbacks do not exceed the limits specified in sub. (1).
ATCP 51.12(2)
(2) Manure storage structure; setback. A waste storage structure may not be located within 350 feet of any property line, or within 350 feet of the nearest point of any public road right-of-way, unless one of the following applies:
ATCP 51.12(2)(a)
(a) The location of the waste storage structure complies with a local ordinance that specifies a shorter setback that is specific to waste storage facilities or waste storage structures.
ATCP 51.12(2)(b)
(b) The waste storage structure existed prior to May 1, 2006. This paragraph does not authorize an expansion, toward a property line or public road right-of-way, of a waste storage structure that is located within 350 feet of that property line or public road right-of-way.
ATCP 51.12(2)(c)
(c) The waste storage structure is a single new waste storage structure constructed no closer to the relevant property line or public road than a waste storage structure that existed on the same tax parcel prior to May 1, 2006, provided that the new structure is no larger than the existing structure and is located within 50 feet of the existing structure.
ATCP 51.12 Note
Note: See definition of “waste storage structure" in s.
ATCP 51.01 (44).
ATCP 51.12(3)
(3) Navigable waters and wetlands. A livestock facility shall comply with an applicable shoreland or wetland zoning ordinance that is enacted within the scope of authority granted under s.
59.692,
61.351 or
62.231, Stats.
ATCP 51.12 Note
Note: Essentially all navigable waters are now protected by ordinances that require building setbacks of 75 feet or more (depending on the ordinance). Zoning restrictions, if any, typically apply to
new or enlarged structures. A zoning ordinance applies for purposes of sub. (3) if it is enacted within the scope of statutory authority under s.
59.692,
61.351 or
62.231, Stats., even if it is also enacted under other authority.
ATCP 51.12(4)
(4) Floodplain. A livestock facility shall comply with an applicable floodplain zoning ordinance that is enacted within the scope of statutory authority under s.
87.30, Stats.
ATCP 51.12 Note
Note: County or local zoning ordinances currently apply to many, but not all, waterways (not all waterways have mapped floodplains). Zoning restrictions, if any, typically apply to
new or enlarged structures. A zoning ordinance applies for purposes of sub. (4) if it is enacted within the scope of statutory authority under s.
87.30, Stats., even if it is also enacted under other authority.
ATCP 51.12(5)(b)
(b) Except as provided in
par. (c), new or substantially altered livestock structures shall be separated from existing wells by the distances required in
chs. NR 811 and
812, regardless of whether the livestock facility operator owns the land on which the wells are located.
ATCP 51.12(5)(c)
(c) Paragraph (b) does not prohibit the alteration of a livestock structure that existed on May 1, 2006, unless that alteration reduces the distance between the livestock structure and an existing well.
ATCP 51.12 Note
Note: DNR rules under chs.
NR 811 and
812 spell out well construction and well location standards to protect water supplies. Violation of well setback requirements in ch.
NR 811 or
812 may prevent use of a well. DNR may grant appropriate variances, as provided in chs.
NR 811 and
812.
ATCP 51.12(6)
(6) Presumption. For purposes of local approval, a livestock facility is presumed to comply with this section if the application for local approval complies with
s. ATCP 51.30.
ATCP 51.12 Note
Note: Under s.
ATCP 51.30, an application must be complete, credible and internally consistent. The application must include an area map, a site map, and a certification that the livestock facility complies with this section (
see Appendix A). A local approval is conditioned upon compliance in fact (
see s.
ATCP 51.34 (4)). The presumption in sub. (6) may be rebutted by clear and convincing evidence in the record (
see s.

(1)
Odor standard. Except as provided in
subs. (2) to
(4), a livestock facility shall have an odor score of at least 500. The operator shall calculate the odor score according to
Appendix A, worksheet 2, or by using the equivalent spreadsheet provided on the department's website. An application for local approval shall include
worksheet 2 or the spreadsheet output.
ATCP 51.14 Note
Note: The spreadsheet equivalent of
Appendix A, worksheet 2 is available on the department's website at
http://livestocksiting.wi.gov/ .
ATCP 51.14 Note
Odor score is based on predicted odor generation (based on size and type of livestock facility), odor practices, and the proximity and density of “affected neighbors." See Appendix A, worksheet 2.
ATCP 51.14 Note
An odor score is a predictive estimate. The standard in sub. (1) applies only for purposes of local livestock facility siting decisions under this chapter. Failure to comply with the standard in sub. (1) does not constitute evidence of a public or private nuisance, negligence, or a taking of property.
ATCP 51.14 Note
Odor control practices may also control air pollution emissions. The department will work to coordinate odor and air emissions field research with DNR, the Wisconsin agricultural stewardship initiative (WASI), and the University of Wisconsin. The department will consider research results when it reviews this chapter at least once every 4 years (see s.
93.90 (2) (c), Stats.). As part of its review, the department will consult with an advisory committee that includes representatives of livestock producers, local government and environmental interests. The department will consider amendments to this rule, as appropriate, based on research findings.
ATCP 51.14(2)
(2) Exemptions. The odor standard in
sub. (1) does not apply to any of the following livestock facilities unless the facility operator voluntarily completes and submits
worksheet 2 or the equivalent spreadsheet output with the operator's application for local approval:
ATCP 51.14(2)(b)
(b) An expanded livestock facility with fewer than 1,000 animal units.
ATCP 51.14(2)(c)
(c) A livestock facility in which all livestock structures will be located at least 2,500 ft. from the nearest affected neighbor.
