(A) The Commonwealth shall provide for a biennial audit of expenditures under its program for the provision of the assistance described in subsection (a)(2)(B), and within 120 days of the end of each fiscal year in which the audit is made, shall report to the Secretary the findings of such audit.

(B) Within 120 days of the end of the fiscal year, the Commonwealth shall provide the Secretary with a statement as to whether the payments received under subsection (a) for that fiscal year exceeded the expenditures by it during that year for which payment is authorized under this section, and if so, by how much, and such other information as the Secretary may require.

(C) (i) If the Secretary finds that there is a substantial failure by the Commonwealth to comply with any of the requirements of subparagraphs (A) and (B), or to comply with the requirements of subsection (b)(1)(A) in the administration of a plan approved under subsection (b)(1)(B), the Secretary shall, except as provided in subparagraph (C)(ii), notify the appropriate agency in the Commonwealth that further payments will not be made to it under subsection (a) until the Secretary is satisfied that there will no longer be any such failure to comply, and until the Secretary is so satisfied, the Secretary shall make no further payments. (ii) The Secretary may suspend the termination of payments under subparagraph (C)(i) for such period as the Secretary determines appropriate, and instead withhold payments provided for under subsection (a), in whole or in part, until the Secretary is satisfied that there will no longer be any failure to comply with the requirements of subparagraphs (A) and (B) and subsection (b)(1)(A), at which time such withheld payments shall be paid. (iii) Upon a finding under subparagraph (C)(i) of a substantial failure to comply with any of the requirements of subparagraphs (A) and (B) and subsection (b)(1)(A), the Secretary may, in addition to or in lieu of any action taken under subparagraphs (C)(i) and (C)(ii), refer the matter to the Attorney General with a request that injunctive relief be sought to require compliance by the Commonwealth of Puerto Rico, and upon suit by the Attorney General in an appropriate district court of the United States and a showing that noncompliance has occurred, appropriate injunctive relief shall issue.
