Any contract entered into, or any grant made, under subsection (a) shall contain such terms and conditions as the Secretary concerned shall by regulation prescribe as being necessary or appropriate to protect the interests of the United States. No contract may be entered into, and no grant may be made under subsection (a), for any purpose that is in violation of any applicable State or local law.
