42 U.S. Code § 239f - Administration
The Secretary may administer any or all of the provisions of this part through Memorandum of Agreement with the head of any appropriate Federal agency.
The head of the agency administering this part or provisions thereof (including any agency head administering such Act  or provisions through a Memorandum of Agreement under subsection (a)) may promulgate such implementing regulations as may be found necessary and appropriate. Initial implementing regulations may be interim final regulations.
 So in original. Probably should be “part”.
