The legislature finds that:
(1) Confined animal feeding operations increase social and environmental impacts in areas where these facilities are located;
(2) The siting of confined animal feeding operations is a complex and technically difficult undertaking requiring assistance to counties and other units of local government as they exercise their land use planning authority;
(3) It is in the interest of the state of Idaho that state departments and agencies use their particular expertise to assist counties and other local governments in the environmental evaluation of appropriate sites for confined animal feeding operations.
