A decision of the Board shall constitute final agency action and be effective upon the date of issuance, unless the decision itself provides otherwise. The Board may reconsider a decision in extraordinary circumstances for sufficient reason. A petition for reconsideration shall be filed within 60 days after the date of a decision. The petition shall, at the time of filing, state with particularity the error claimed and include all arguments and supporting documents. The petition may include a request that the Board stay the effectiveness of the decision for which reconsideration is sought. No answer to a petition for reconsideration is required unless so ordered by the Board. The filing, pendency, or denial of a petition for reconsideration shall not operate to stay the effectiveness or affect the finality of the decision involved unless so ordered by the Board. A petition for reconsideration need not be filed to exhaust administrative remedies.
