(a) Written notification, as used in section 6(b) of the Act (7 U.S.C. 499f (b)), means:

(1) Any written statement reporting or complaining of a violation of the Act made by any officer or agency of any State or Territory having jurisdiction over licensees or persons subject to license, or a person filing a complaint under section 6(a), or any other interested person who has knowledge of or information regarding a possible violation of the Act, other than an employee of an agency of USDA administering the Act;

(2) Any written notice of intent to preserve the benefits of, or any claim for payment from, the trust established under section 5 of the Act (7 U.S.C. 499e);

(3) Any official certificate(s) of the United States Government or States or Territories of the United States; or

(4) Any public legal filing or other published document describing or alleging a violation of the Act.

(b) Any written notification may be filed by delivering the written notification to any office of USDA or any official of USDA responsible for administering the Act. Any written notification published in any public forum, including, but not limited to, a newspaper or an internet website shall be deemed filed upon visual inspection by any office of USDA or any official of USDA responsible for administering the Act. A written notification which is so filed, or any expansion of an investigation resulting from any indication of additional violations of the Act found as a consequence of an investigation based on written notification or complaint, also shall be deemed to constitute a complaint under section 13(a) of the Act (7 U.S.C. 499m(a)).

(c) Upon becoming aware of a complaint under section 6(a) or written notification under 6(b) of the Act (7 U.S.C. 499f (a) or (b)) by means described in paragraph (a) and (b) of this section, the Secretary will determine if reasonable grounds exist to conduct an investigation of such complaint or written notification for disciplinary action. If the investigation substantiates the existence of violations of the Act, a formal disciplinary complaint may be issued by the Secretary as described in section 6(c)(2) of the Act (7 U.S.C. 499f(c)(2)).

(d) Whenever an investigation, initiated as described in section 6(c) of the Act (7 U.S.C. 499f(c)(2)), is commenced, or expanded to include new violations of the Act, notice shall be given by the Secretary to the subject of the investigation within thirty (30) days of the commencement or expansion of the investigation. Within one hundred and eighty (180) days after giving initial notice, the Secretary shall provide the subject of the investigation with notice of the status of the investigation, including whether the Secretary intends to issue a complaint under section 6(c)(2) of the Act (7 U.S.C. 499f(e)(2)), terminate the investigation, or continue or expand the investigation. Thereafter, the subject of the investigation may request in writing, no more frequently than every ninety (90) days, a status report from the Director of the PACA Division who shall respond to the written request within fourteen (14) days of receiving the request. When an investigation is terminated, the Secretary shall, within fourteen (14) days, notify the subject of the termination of the investigation. In every case in which notice or response is required under this paragraph (d), such notice or response shall be accomplished by personal service; or by posting the notice or response by certified or registered mail, or commercial or private delivery service to the last known address of the subject of the investigation; or by sending the notice or response by any electronic means such as registered email, that provides proof of receipt to the electronic mail address or phone number of the subject of the investigation.
