Any county which has become a part of the livestock inspection area by petition and which adjoins a noninspection area may withdraw from the inspection area by a petition requesting withdrawal. The petition shall be signed by a majority of the owners of livestock in the county seeking withdrawal. The petition shall be filed with the board. The board shall at its next regular or special meeting enter a resolution approving the withdrawal, which action removes the county described in the petition from the ownership inspection area. No area seeking withdrawal may be smaller than a county.
