We consider a complete open riemannian manifold M of nonnegative Ricci curvature and a rectifiable hypersurface in M which satisfies some local minimizing property. We prove a structure theorem for M and a regularity theorem for . More precisely, a covering space of M is shown to split off a compact domain and is shown to be a smooth totally geodesic submanifold. This generalizes a theorem due to Kasue and Meyer.
