What it does

GENERAL. This bill provides for the regulation of animal feeding operations by the department of natural resources (DNR), including the storage and application of manure originating from such operations (Code chapter 459). An animal feeding operation is an area or building in which agricultural animals (cattle, swine, horses, sheep, chickens, turkeys, or fish) are confined for days or more in any 12-month period, and all associated structures used for the storage of manure. A confinement feeding operation is an animal feeding operation in which animals are confined to areas which are totally roofed.
