(a) If the Commission, after having found reason to believe and after reviewing the respondent's written response and the reviewing officer's recommendation, determines by an affirmative vote of at least four (4) of its members, that the respondent has violated 52 U.S.C. 30104(a) and the amount of the civil money penalty, the Commission shall authorize the reviewing officer to notify the respondent by letter of its final determination.

(b) If the Commission, after reviewing the reason to believe finding, the respondent's written response, and the reviewing officer's written recommendation, determines by an affirmative vote of at least four (4) of its members, that no violation has occurred (either because the Commission had based its reason to believe finding on a factual error or because the respondent used best efforts to file in a timely manner) or otherwise terminates its proceedings, the Commission shall authorize the reviewing officer to notify the respondent by letter of its final determination.

(c) The Commission will modify the proposed civil money penalty only if the respondent is able to demonstrate that the amount of the proposed civil money penalty was calculated on an incorrect basis.

(d) When the Commission makes a final determination under this section, the statement of reasons for the Commission action will, unless otherwise indicated by the Commission, consist of the reasons provided by the reviewing officer for the recommendation, if approved by the Commission, although statements setting forth additional or different reasons may also be issued. If the reviewing officer's recommendation is modified or not approved, the Commission will indicate the grounds for its action and one or more statements of reasons may be issued.
