(a) Before debarring an IPA, the OIG shall send the IPA written notice of the proposed debarment. The notice shall be sent in a manner that provides evidence of its receipt and shall:

(1) State that debarment is being considered;

(2) Identify the reasons for the proposed debarment sufficient to put the IPA on notice of the conduct or transaction(s) upon which a debarment proceeding is based;

(3) Identify the regulatory provisions governing the debarment proceeding; and

(4) State that debarment may be for a period of up to three years or longer under extraordinary circumstances. If the OIG has determined that extraordinary circumstances warranting debarment in excess of three years may exist, the notice shall so state.

(b) A copy of the notice also shall be sent to the affected recipient(s), if any, which may comment on the proposed action in the time frame set out in §1641.9.
