Definitions

Agricultural animal” means an animal confined in an agricultural facility.

 Agricultural facility” means a lot, building, or structure, which is used for the commercial production of animals in an animal facility.

Agronomic rate” is the animal manure and other animal by-products application rate designed:  (1) to provide the amount of nitrogen needed by the food crop, feed crop, fiber crop, cover crop, or vegetation grown on the land and (2) to minimize the amount of nitrogen in the animal manure that passes below the root zone of the crop or vegetation grown on the land to the groundwater and (3) to provide the amount of other organic and inorganic plant nutrients which promote crop or vegetative growth, such as calcium-carbonate equivalency and (4) to provide the amount of phosphorus needed by the crop or vegetation grown on the land without causing an excessive build up of phosphorus in the soil.

Animal” means any domesticated animal.

Animal by-product” means a secondary or incidental product of animal production that may include bedding, spilled feed, water or soil, milking center washwater, contaminated milk, hair, feathers, dead animals or other debris.  This definition may also refer to dead animal or animal manure compost.

Animal facility” means an agricultural facility where animals are confined and fed or maintained for a total of forty-five days or more in a twelve‑month period and crops, vegetative, forage growth, or post harvest residues are not sustained in the normal growing season over any portion of the lot or facility.  Structures used for the storage of animal manure and other animal by-products from animals in the operation also are part of the animal facility.  Two or more animal facilities under common ownership or management are considered to be a single animal facility if they are adjacent or utilize a common system for animal manure storage.
