46 C.F.R. § 202.1
The rules of this part prescribe procedures relating to Secretarial review of any decision, report, order or action of the Maritime Subsidy Board (Board) pursuant to Department Order 117-A (31 FR 8087, 15331). Section 6 of Department Order 117-A is reprinted here for the convenience of the public.
.02 The Secretary may on his own motion review all actions of the Maritime Subsidy Board other than those referred to in paragraph .01 of this section by entering a written order stating that he elects to review the action of the Board. Any person having an interest in any action of the Board under this paragraph shall have the privilege of submitting to the Secretary within ten (10) days after the date of such Board action, a request that the Secretary undertake such review. Such request shall be in writing and shall state the grounds upon which the person submitting the same relies and his interest in the action for which review is requested. Ten (10) copies of such requests shall be submitted to the Secretary. Any other person having an interest in such matter shall have the privilege of submitting within fifteen (15) days after the date of the Board's action, a written request that the Secretary not exercise such review. Copies of request that the Secretary undertake or not exercise review will be open for public inspection at the office of the Secretary of the Board. If either a request that the Secretary undertake review or a request that he not exercise review is submitted within the time prescribed, an action of the Board shall be final in ten (10) days after expiration of the time prescribed for submission of a request that review not be exercised unless the Secretary, prior to the expiration of the ten (10) days, enters a written order stating that he elects to review the action of the Board. If neither a request that the Secretary undertake review nor a request that he not exercise review is submitted within the time prescribed, an action of the Board shall be final in twenty (20) days after the date of such action unless the Secretary, prior to expiration of the twenty (20) days, enters a written order stating that he elects to review the action of the Board. Copies of all orders for review shall be served upon the Board, and upon all persons filing requests as herein described.
.03 If a timely petition for reconsideration is filed under the rules prescribed by the Board, the time for filing a petition or request for review by the Secretary under paragraph .01 or .02 of this section, respectively, or the entry of an order by the Secretary on his own motion electing to review an action of the Board under paragraph .01 or .02 of this section, shall, in the case of actions under paragraph .01 of this section run from the date of service of the Board's action and, in the case of actions under paragraph .02 of this section, run from the date of the Board's action, finally disposing of the issues presented by the petition for reconsideration.
.04 In computing any period of time under this section, the time begins with the day following the act, event, or default, and includes the last day of the period unless it is Saturday, Sunday, or national legal holiday, in which event the period runs until the end of the next day which is not a Saturday, Sunday, or such holiday. The prescribed time for action by the Secretary in a proceeding in which additional days have been added pursuant to the provisions of this paragraph shall be extended by the total of such additional days.
.05 Petitions and requests for review by the Secretary shall not be filed:
.06 The Secretary may, for good cause and/or in order to prevent undue hardship in any particular case, waive or modify any procedural provision of this section by written order.
