(a) Where one or the other of the Governments on its own initiative seeks the approval of the commission for the use, obstruction or diversion of waters with respect to which under Articles III or IV of the Treaty the approval of the Commission is required, it shall present to the Commission an application setting forth as fully as may be necessary for the information of the Commission the facts upon which the application is based and the nature of the order of approval desired.

(b) Where a person seeks the approval of the Commission for the use, obstruction or diversion of waters with respect to which under Articles III or IV of the Treaty the approval of the Commission is required, he shall prepare an application to the Commission and forward it to the Government within whose jurisdiction such use, obstruction or diversion is to be made, with the request that the said application be transmitted to the Commission. If such Government transmits the application to the Commission with a request that it take appropriate action thereon, the same shall be filed by the Commission in the same manner as an application presented in accordance with paragraph (a) of this section. Transmittal of the application to the Commission shall not be construed as authorization by the Government of the use, obstruction or diversion proposed by the applicant. All applications by persons shall conform, as to their contents, to the requirements of paragraph (a) of this section.

(c) Where the Commission has issued an Order approving a particular use, obstruction or diversion, in which it has specifically retained jurisdiction over the subject matter of an application and has reserved the right to make further orders relating thereto, any Government or person entitled to request the issuance of such further order may present to the Commission a request, setting forth the facts upon which it is based and the nature of the further order desired. On receipt of the request, the Commission shall proceed in accordance with the terms of the Order in which the Commission specifically retained jurisdiction. In each case the secretaries shall notify both Governments and invite their comments before the request is complied with.
