28 C.F.R. § 81.2
Reports of child abuse required by 42 U.S.C. 13031 shall be made to the local law enforcement agency or local child protective services agency that has jurisdiction to investigate reports of child abuse or to protect child abuse victims in the land area or facility in question. Such agencies are hereby respectively designated as the agencies to receive and investigate such reports, pursuant to 42 U.S.C. 13031(d) , with respect to federal lands and federally operated or contracted facilities within their respective jurisdictions, provided that such agencies, if non-federal, enter into formal written agreements to do so with the Attorney General, her delegate, or a federal agency with jurisdiction for the area or facility in question. If the child abuse reported by the covered professional pursuant to 42 U.S.C. 13031 occurred outside the federal area or facility in question, the designated local law enforcement agency or local child protective services agency receiving the report shall immediately forward the matter to the appropriate authority with jurisdiction outside the federal area in question.
