For purposes of this subchapter, all of the following shall apply:
 1. Two or more animal feeding operations under common ownership or management are deemed to be a single animal feeding operation if they are adjacent or utilize a common system for manure storage. For purposes of determining whether two or more confinement feeding operations are adjacent, all of the following must apply:

 a. At least one confinement feeding operation structure must be constructed on or after March 21, 1996.
 b. A confinement feeding operation structure which is part of one confinement feeding operation is separated by less than a minimum required distance from a confinement feeding operation structure which is part of the other confinement feeding operation. The minimum required distance shall be as follows:

 (1) (a) One thousand two hundred fifty feet for a confinement feeding operation having an animal unit capacity of less than three thousand animal units for animals other than swine maintained as part of a swine farrowing and gestating operation or farrow-to-finish operation, or cattle maintained as part of a cattle operation.

 (b) One thousand two hundred fifty feet for a confinement feeding operation having an animal unit capacity of less than one thousand two hundred fifty animal units for swine maintained as part of a farrowing and gestating operation, less than two thousand seven hundred animal units for swine maintained as part of a farrow-to-finish operation, or less than four thousand animal units for cattle maintained as part of a cattle operation.
 (2) (a) One thousand five hundred feet for a confinement feeding operation having an animal unit capacity of three thousand or more but less than five thousand animal units for animals other than swine maintained as part of a swine farrowing and gestating operation or farrow-to-finish operation, or cattle maintained as part of a cattle operation.

 (b) One thousand five hundred feet for a confinement feeding operation having an animal unit capacity of one thousand two hundred fifty or more but less than two thousand animal units for swine maintained as part of a swine farrowing and gestating operation, two thousand seven hundred or more but less than five thousand four hundred animal units for swine maintained as part of a farrow-to-finish operation, or four thousand or more but less than six thousand five hundred animal units for cattle maintained as part of a cattle operation.
 (3) (a) Two thousand five hundred feet for a confinement feeding operation having an animal unit capacity of five thousand or more animal units for animals other than swine maintained as part of a swine farrowing and gestating operation or farrow-to-finish operation, or cattle maintained as part of a cattle operation.

 (b) Two thousand five hundred feet for a confinement feeding operation having an animal unit capacity of two thousand or more animal units for swine maintained as part of a swine farrowing and gestating operation, five thousand four hundred animal units or more for swine maintained as part of a farrow-to-finish operation, or six thousand five hundred or more animal units for cattle maintained as part of a cattle operation.

Terms Used In Iowa Code 459.201

  • Animal: means cattle, swine, horses, sheep, chickens, turkeys, or fish. See Iowa Code 459.102
  • Animal feeding operation: means a lot, yard, corral, building, or other area in which animals are confined and fed and maintained for forty-five days or more in any twelve-month period, and all structures used for the storage of manure from animals in the operation. See Iowa Code 459.102
  • Animal unit: means a unit of measurement based upon the product of multiplying the number of animals of each category by a special equivalency factor as follows:
     a. See Iowa Code 459.102
  • Animal unit capacity: means a measurement used to determine the maximum number of animal units that may be maintained as part of an animal feeding operation at any one time, including as provided in sections 459. See Iowa Code 459.102
  • Confinement feeding operation: means an animal feeding operation in which animals are confined to areas which are totally roofed. See Iowa Code 459.102
  • Confinement feeding operation structure: means an animal feeding operation structure that is part of a confinement feeding operation. See Iowa Code 459.102
  • Department: means the department of natural resources created pursuant to section 455A. See Iowa Code 459.102
  • following: when used by way of reference to a chapter or other part of a statute mean the next preceding or next following chapter or other part. See Iowa Code 4.1
  • Manure: means animal excreta or other commonly associated wastes of animals, including but not limited to bedding, litter, or feed losses. See Iowa Code 459.102
  • Public thoroughfare: means a road, street, or bridge that is constructed or maintained by the state or a political subdivision. See Iowa Code 459.102
 2. A confinement feeding operation structure is “constructed” when any of the following occurs:

 a. Excavation for a proposed confinement feeding operation structure or proposed expansion of an existing confinement feeding operation structure, including excavation for the footings of the confinement feeding operation structure.
 b. Forms for concrete are installed for a proposed confinement feeding operation structure or the proposed expansion of an existing confinement feeding operation structure.
 c. Piping for the movement of manure is installed within or between confinement feeding operation structures as proposed or proposed to be expanded.
 3. In calculating the animal unit capacity of a confinement feeding operation, the animal unit capacity shall include the animal unit capacity of all confinement feeding operation buildings which are part of the confinement feeding operation, unless a confinement feeding operation building has been abandoned.
 4. A confinement feeding operation structure is abandoned if the confinement feeding operation structure has been razed, removed from the site of a confinement feeding operation, filled in with earth, or converted to uses other than a confinement feeding operation structure so that it cannot be used as a confinement feeding operation structure without significant reconstruction.
 5. All distances between locations of objects provided in this part shall be measured in feet from their closest points, as provided by rules adopted by the department. However, a distance between a public thoroughfare and a confinement feeding operation structure shall be measured from the portion of the right-of-way which is closest to the confinement feeding operation structure.
