(a) A meeting or a portion of a meeting will be closed to public observation, or information as to such meeting or portion of a meeting will be withheld, only by recorded vote of a majority of the Members of the Board when it is determined that the meeting or the portion of the meeting or the withholding of information qualifies for exemption under § 1632.5. Votes by proxy are not allowed.

(b) Except as provided in paragraph (c) of this section, a separate vote of the Members of the Board will be taken with respect to the closing or the withholding of information as to each meeting or portion thereof which is proposed to be closed to public observation or with respect to which information is proposed to be withheld pursuant to this section.

(c) A single vote may be taken with respect to a series of meetings, a portion or portions of which are proposed to be closed to public observation or with respect to any information concerning such series of meetings proposed to be withheld, so long as each meeting or portion thereof in such series involves the same particular matters and is scheduled to be held no more than thirty days after the initial meeting in such series.

(d) Whenever any person's interests may be directly affected by a portion of the meeting for any of the reasons referred to in exemption (a)(5), (a)(6) or (a)(7) of § 1632.5 of this part, such person may request in writing to the Secretary of the Board that such portion of the meeting be closed to public observation. The Secretary, or in his or her absence, the Acting Secretary of the Board, shall transmit the request to the members and upon the request of any one of them a recorded vote shall be taken whether to close such meeting to public observation.

(e) Within one day of any vote taken pursuant to paragraphs (a) through (d) of this section, the agency will make publicly available at the Board's External Affairs Office a written copy of such vote reflecting the vote of each member on the question.
