Section 604.48 - Appeal from Chief Counsel decision(a) Each party adversely affected by the Chief Counsel's office decision may file an appeal with the Administrator within 21 days of the date of the Chief Counsel's issued his or her decision. Each party may file a reply to an appeal within 21 days after it is served on the party. Filing and service of appeals and replies shall be by personal delivery consistent with §§ 604.30 and 604.31 .(b) If an appeal is filed, the Administrator reviews the entire record and issues a final agency decision based on the record that either accepts, rejects, or modifies the Chief Counsel's decision within 30 days of the due date of the reply. If no appeal is filed, the Administrator may take review of the case on his or her own motion. If the Administrator finds that the respondent is not in compliance with this part, the final agency order shall include a statement of corrective action, if appropriate, and identify remedies.(c) If no appeal is filed, and the Administrator does not take review of the decision by the office on the Administrator's own motion, the Chief Counsel's decision shall take effect as the final agency decision and order on the twenty-first day after the actual date the Chief Counsel's decision was issued.(d) The failure to file an appeal is deemed a waiver of any rights to seek judicial review of the Chief Counsel's decision that becomes a final agency decision by operation of paragraph (c) of this section.
