In Idaho, counties regulate confined animal feeding operation (CAFO) siting. Dairies and beef feedlots must apply for county CAFO permits before they can open. Depending on the county, either planning and zoning boards or commissioners approve or deny the applications. Idaho statute requires the opportunity for public input before CAFOs are sited. At a minimum, the board of county commissioners must hold at least one public hearing at which the public may comment on a proposed site. Only members of the public with primary residences within one mile of a proposed site may comment at the hearing. However, this distance may be increased by the board. The board must consider public comments when deciding whether to approve or reject a proposed site.
