Sponsor(s)' responsibility.

(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 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.
