(a) On non-Federal land, sponsor(s) are responsible for financing and performing without cost to the Federal Government, needed operation and maintenance (O&M) of project measures installed with Federal financial assistance.
(b) The Federal agency administering Federal land involving project measures is responsible either for performing or requiring the performance of O&M on land administered by that agency. If project measures benefit both Federal and non-Federal land or interests, the O&M may be performed by the Federal agency, the sponsor(s), or both as mutually agreed by the Federal agency, sponsor(s), and NRCS. If O&M of project measures is performed by mutual agreement, the cost of O&M may be shared by the Federal agency and sponsor(s) as agreed.
(c) The sponsor(s) shall obtain NRCS approval before modifying a project measure of changing land use to fulfill a different purpose.
