(a) At any time prior to the filing of objections to the findings and/or order, a complainant may withdraw his or her complaint under any of the statutes listed in § 24.100(a) by filing a written withdrawal with the Assistant Secretary. The Assistant Secretary will then determine whether to approve the withdrawal. The Assistant Secretary will notify the respondent of the approval of any withdrawal. If the complaint is withdrawn because of settlement under the Energy Reorganization Act, the Clean Air Act, the Safe Drinking Water Act, or the Toxic Substances Control Act, the settlement must be submitted for approval in accordance with paragraph (d) of this section. Parties to settlements under the Federal Water Pollution Control Act, the Solid Waste Disposal Act, and the Comprehensive Environmental Response, Compensation and Liability Act are encouraged to submit their settlements for approval. After the filing of objections to the Assistant Secretary's findings and/or order, a complainant may not withdraw his or her complaint.

(b) The Assistant Secretary may withdraw his or her findings and/or order, at any time before the expiration of the 30-day objection period described in § 24.106, provided that no objection has yet been filed, and substitute new findings and/or a new order. The date of the receipt of the substituted findings and/or order will begin a new 30-day objection period.

(c) At any time before the Assistant Secretary's findings or order become final, a party may withdraw its objections to the Assistant Secretary's findings or order by filing a written withdrawal with the ALJ. If a case is on review with the ARB, a party may withdraw its petition for review of an ALJ's decision at any time before that decision becomes final by filing a written withdrawal with the ARB. The ALJ or the ARB, as the case may be, will determine whether to approve the withdrawal of the objections or the petition for review. If the ALJ approves a request to withdraw objections to the Assistant Secretary's findings or order, and there are no other pending objections, the Assistant Secretary's findings and order will become the final order of the Secretary. If the ARB approves a request to withdraw a petition for review of an ALJ decision, and there are no other pending petitions for review of that decision, the ALJ's decision will become the final order of the Secretary. If the objections are withdrawn because of settlement under the Energy Reorganization Act, the Clean Air Act, the Safe Drinking Water Act, or the Toxic Substances Control Act, the settlement must be submitted for approval in accordance with paragraph (d) of this section.

(d)(1) Investigative settlements under the Energy Reorganization Act, the Clean Air Act, the Safe Drinking Water Act, and the Toxic Substances Control Act. At any time after the filing of a complaint, and before the findings and/or order are objected to or become a final order by operation of law, the case may be settled if the Assistant Secretary, the complainant and the respondent agree to a settlement. The Assistant Secretary's approval of a settlement reached by the respondent and the complainant demonstrates his or her consent and achieves the consent of all three parties.

(2) Adjudicatory settlements under the Energy Reorganization Act, the Clean Air Act, the Safe Drinking Water Act, and the Toxic Substances Control Act. At any time after the filing of objections to the Assistant Secretary's findings and/or order, the case may be settled if the participating parties agree to a settlement and the settlement is approved by the ALJ if the case is before the judge, or by the ARB if the ARB has accepted the case for review. A copy of the settlement must be filed with the administrative law judge or the ARB, as the case may be.

(e) Any settlement approved by the Assistant Secretary, the administrative law judge, or the ARB will constitute the final order of the Secretary and may be enforced pursuant to § 24.113.

(a) Except as provided under paragraphs (b) through (d) of this section, within 60 days after the issuance of a final order (including a decision issued by the Secretary upon his or her discretionary review) for which judicial review is available, any person adversely affected or aggrieved by the order may file a petition for review of the order in the United States Court of Appeals for the circuit in which the violation allegedly occurred or the circuit in which the complainant resided on the date of the violation. A final order of the ARB (or a decision issued by the Secretary upon his or her discretionary review) is not subject to judicial review in any criminal or other civil proceeding.

(b) Under the Federal Water Pollution Control Act, within 120 days after the issuance of a final order (including a decision issued by the Secretary upon his or her discretionary review) for which judicial review is available, any person adversely affected or aggrieved by the order may file a petition for review of the order in the United States Court of Appeals for the circuit in which the violation allegedly occurred or the circuit in which the complainant resided on the date of the violation.

(c) Under the Solid Waste Disposal Act, within 90 days after the issuance of a final order (including a decision issued by the Secretary upon his or her discretionary review) for which judicial review is available, any person adversely affected or aggrieved by the order may file a petition for review of the order in the United States Court of Appeals for the circuit in which the violation allegedly occurred or the circuit in which the complainant resided on the date of the violation.

(d) Under the Comprehensive Environmental Response, Compensation and Liability Act, after the issuance of a final order (including a decision issued by the Secretary upon his or her discretionary review) for which judicial review is available, any person adversely affected or aggrieved by the order may file a petition for review of the order in the United States district court in which the violation allegedly occurred. For purposes of judicial economy and consistency, when a final order under the Comprehensive Environmental Response, Compensation and Liability Act also is issued under any other statute listed in § 24.100(a), the adversely affected or aggrieved person may file a petition for review of the entire order in the United States Court of Appeals for the circuit in which the violation allegedly occurred or the circuit in which the complainant resided on the date of the violation. The time for filing a petition for review of an order issued under the Comprehensive Environmental Response, Compensation and Liability Act and any other statute listed in § 24.100(a) is determined by the time period applicable under the other statute(s).

(e) If a timely petition for review is filed, the record of a case, including the record of proceedings before the administrative law judge, will be transmitted by the ARB or the ALJ, as appropriate, to the appropriate court pursuant to the Federal Rules of Appellate Procedure and the local rules of the court.

Whenever any person has failed to comply with an order by an ALJ issued under the Energy Reorganization Act, with the exception of any award of compensatory damages, or with a final order of the Secretary, including final orders approving settlement agreements as provided under § 24.111(d), the Secretary may file a civil action seeking enforcement of the order in the United States district court for the district in which the violation was found to have occurred. Whenever any person has failed to comply with an order by an ALJ issued under the Energy Reorganization Act, with the exception of any award of compensatory damages, or with a final order of the Secretary under either the Energy Reorganization Act or the Clean Air Act, the person on whose behalf the order was issued also may file a civil action seeking enforcement of the order in the United States district court for the district in which the violation was found to have occurred.

(a) If there is no final order of the Secretary, one year has passed since the filing of a complaint under the Energy Reorganization Act, and there is no showing that there has been delay due to the bad faith of the complainant, the complainant may bring an action at law or equity for de novo review in the appropriate district court of the United States, which will have jurisdiction over such an action without regard to the amount in controversy.

(b) Fifteen days in advance of filing a complaint in Federal court, a complainant must file with the Assistant Secretary, the ALJ, or the ARB, depending upon where the proceeding is pending, a notice of his or her intention to file such complaint. The notice must be served on all parties to the proceeding. A copy of the notice must be served on the Regional Administrator, the Assistant Secretary, Occupational Safety and Health Administration, and on the Associate Solicitor, Division of Fair Labor Standards, U.S. Department of Labor. The complainant shall file and serve a copy of the district court complaint on the above as soon as possible after the district court complaint has been filed with the court.

In special circumstances not contemplated by the provisions of this part, or for good cause shown, the ALJ or the ARB on review may, upon application, after three days notice to all parties, waive any rule or issue any orders that justice or the administration of any of the statutes listed in § 24.100(a) requires.
