(a) The Commission is authorized to notify, in the manner provided in § 46-17-80, all producers and handlers affected by a proposed marketing order to file with the Commission within ten days from the receipt of the notice, a report properly certified, showing:

(1) The name and address of the handler;

(2) The quantities of the affected commodity handled by the handler in the marketing season next preceding the filing of the report;

(3) The names and addresses of all producers of the affected commodity who may be directly affected by the proposed marketing order, from whom such handler received the affected commodity in the marketing season next preceding the filing of the report;

(4) The quantities of the affected commodity received by the handler from each producer in the marketing season next preceding the filing of the report.

(b) The Commission shall also mail a copy of the notice to file the report to all handlers of the agricultural commodity whose addresses appear upon the lists on file in the Department or in the office of the Commission who may be directly affected by the order.

(c) Each handler of the affected commodity shall file the verified report with the Commission within the time specified herein. Failure or refusal of any handler to file the report shall not invalidate any proceeding taken or marketing order issued, amended, or terminated hereunder. The Commission is authorized to proceed on the basis of such information and reports as may otherwise be made available.

(d) Any qualified person may at any time have his name placed upon any list for which he qualifies by delivering or mailing his name, address, and other information to the Commission, and in such case the qualifications of such person shall be verified, and if he qualifies, his name shall be placed upon such list.

(e) From the reports filed with the Commission, there shall be prepared a list of the names and addresses of the producers and the volume of the affected commodity produced or marketed by all the producers and a list of the names and addresses of the handlers and the volume of the affected commodity handled by all the handlers in the next preceding marketing season. Such lists shall constitute conclusive lists for use in any finding made by the Commission.

(f) The information contained in the individual reports of handlers filed with the Commission pursuant to the provisions of this section shall not be made public in such form but the information contained in the reports may be prepared in combined form for the affected commodity in the formulation and enforcement of a marketing order, or may be made available pursuant to court order, but shall not be made available to anyone for private purposes. The Commission shall compile and make available this information and lists of names and addresses. After every hearing the hearing examiner shall compile and bring lists up to date in accordance with evidence and information obtained at the hearing, and he may subpoena witnesses, books and records for such purpose.
