State and Regional Development Plans and implementing investment programs, and any multistate subregional plans which may be developed, shall be annually reviewed and approved by the Commission in accordance with section 101(b) of this Act. An application for a grant or for any other assistance for a specific project under this Act shall be made through the State member of the Commission representing such applicant, and such State member shall evaluate the application for approval. Only applications for grants or other assistance for specific projects shall be approved which are certified by the State member and determined by the Federal Cochairman to implement the Commission-approved State development plan; to be included in the Commission-approved implementing investment program; to have adequate assurance that the project will be properly administered, operated, and maintained; and to otherwise meet the requirements for assistance under this Act. After the approval of the appropriate State development plan and implementing investment program, certification by a State member of an application for a grant or other assistance for a specific project pursuant to this section shall, when joined by an affirmative vote of the Federal Cochairman for such project, be deemed to satisfy the requirements for affirmative votes for decisions under section 101(b) of this Act.
