(A) a person owning or operating a pipeline facility; or

(B) a contractor or subcontractor of such a person.

(b) Department of Labor Complaint Procedure.—

(1) Filing and notification.—A person who believes that he or she has been discharged or otherwise discriminated against by any person in violation of subsection (a) may, not later than 180 days after the date on which such violation occurs, file (or have any person file on his or her behalf) a complaint with the Secretary of Labor alleging such discharge or discrimination. Upon receipt of such a complaint, the Secretary of Labor shall notify, in writing, the person or persons named in the complaint and the Secretary of Transportation of the filing of the complaint, of the allegations contained in the complaint, of the substance of evidence supporting the complaint, and of the opportunities that will be afforded to such person or persons under paragraph (2).

(2) Investigation; preliminary order.—

(A) In general.—Not later than 60 days after the date of receipt of a complaint filed under paragraph (1) and after affording the person or persons named in the complaint an opportunity to submit to the Secretary of Labor a written response to the complaint and an opportunity to meet with a representative of the Secretary of Labor to present statements from witnesses, the Secretary of Labor shall conduct an investigation and determine whether there is reasonable cause to believe that the complaint has merit and notify in writing the complainant and the person or persons alleged to have committed a violation of subsection (a) of the Secretary of Labor's findings. If the Secretary of Labor concludes that there is reasonable cause to believe that a violation of subsection (a) has occurred, the Secretary of Labor shall include with the Secretary of Labor's findings with a preliminary order providing the relief prescribed by paragraph (3)(B). Not later than 60 days after the date of notification of findings under this subparagraph, any person alleged to have committed a violation or the complainant may file objections to the findings or preliminary order, or both, and request a hearing on the record. The filing of such objections shall not operate to stay any reinstatement remedy contained in the preliminary order. Such hearings shall be conducted expeditiously. If a hearing is not requested in such 60-day period, the preliminary order shall be deemed a final order that is not subject to judicial review.

(B) Requirements.—

(i) Required showing by complainant.—The Secretary of Labor shall dismiss a complaint filed under this subsection and shall not conduct an investigation otherwise required under subparagraph (A) unless the complainant makes a prima facie showing that any behavior described in subsection (a) was a contributing factor in the unfavorable personnel action alleged in the complaint.

(ii) Showing by employer.—Notwithstanding a finding by the Secretary of Labor that the complainant has made the showing required under clause (i), no investigation otherwise required under subparagraph (A) shall be conducted if the employer demonstrates, by clear and convincing evidence, that the employer would have taken the same unfavorable personnel action in the absence of that behavior.

(iii) Criteria for determination by Secretary.—The Secretary of Labor may determine that a violation of subsection (a) has occurred only if the complainant demonstrates that any behavior described in subsection (a) was a contributing factor in the unfavorable personnel action alleged in the complaint.

(iv) Prohibition.—Relief may not be ordered under subparagraph (A) if the employer demonstrates by clear and convincing evidence that the employer would have taken the same unfavorable personnel action in the absence of that behavior.

(3) Final order.—

(A) Deadline for issuance; settlement agreements.—Not later than 90 days after the date of conclusion of a hearing under paragraph (2), the Secretary of Labor shall issue a final order providing the relief prescribed by this paragraph or denying the complaint. At any time before issuance of a final order, a proceeding under this subsection may be terminated on the basis of a settlement agreement entered into by the Secretary of Labor, the complainant, and the person or persons alleged to have committed the violation.

(B) Remedy.—If, in response to a complaint filed under paragraph (1), the Secretary of Labor determines that a violation of subsection (a) has occurred, the Secretary of Labor shall order the person or persons who committed such violation to—

(i) take affirmative action to abate the violation;

(ii) reinstate the complainant to his or her former position together with the compensation (including back pay) and restore the terms, conditions, and privileges associated with his or her employment; and

(iii) provide compensatory damages to the complainant.

If such an order is issued under this paragraph, the Secretary of Labor, at the request of the complainant, shall assess against the person or persons against whom the order is issued a sum equal to the aggregate amount of all costs and expenses (including attorney's and expert witness fees) reasonably incurred, as determined by the Secretary of Labor, by the complainant for, or in connection with, the bringing the complaint upon which the order was issued.

(C) Frivolous complaints.—If the Secretary of Labor finds that a complaint under paragraph (1) is frivolous or has been brought in bad faith, the Secretary of Labor may award to the prevailing employer a reasonable attorney's fee not exceeding $1,000.

(4) Review.—

(A) Appeal to court of appeals.—Any person adversely affected or aggrieved by an order issued under paragraph (3) may obtain review of the order in the United States Court of Appeals for the circuit in which the violation, with respect to which the order was issued, allegedly occurred or the circuit in which the complainant resided on the date of such violation. The petition for review must be filed not later than 60 days after the date of issuance of the final order of the Secretary of Labor. Review shall conform to chapter 7 of title 5, United States Code. The commencement of proceedings under this subparagraph shall not, unless ordered by the court, operate as a stay of the order.

(B) Limitation on collateral attack.—An order of the Secretary of Labor with respect to which review could have been obtained under subparagraph (A) shall not be subject to judicial review in any criminal or other civil proceeding.

(5) Enforcement of order by secretary of labor.—Whenever any person has failed to comply with an order issued under paragraph (3), the Secretary of Labor may file a civil action in the United States district court for the district in which the violation was found to occur to enforce such order. In actions brought under this paragraph, the district courts shall have jurisdiction to grant all appropriate relief, including, but not to be limited to, injunctive relief and compensatory damages.

(6) Enforcement of order by parties.—

(A) Commencement of action.—A person on whose behalf an order was issued under paragraph (3) may commence a civil action against the person or persons to whom such order was issued to require compliance with such order. The appropriate United States district court shall have jurisdiction, without regard to the amount in controversy or the citizenship of the parties, to enforce such order.

(B) Attorney fees.—The court, in issuing any final order under this paragraph, may award costs of litigation (including reasonable attorney and expert witness fees) to any party whenever the court determines such award of costs is appropriate.

(c) Mandamus.—Any nondiscretionary duty imposed by this section shall be enforceable in a mandamus proceeding brought under section 1361 of title 28, United States Code.

(d) Nonapplicability To Deliberate Violations.—Subsection (a) shall not apply with respect to an action of an employee of an employer who, acting without direction from the employer (or such employer's agent), deliberately causes a violation of any requirement relating to pipeline safety under this chapter or any other law of the United States.
