A civil action authorized to be commenced under this section shall be referred to the Attorney General for appropriate action, except that the Secretary shall not be required to refer to the Attorney General a violation of this subchapter if the Secretary believes that the administration and enforcement of this subchapter would be adequately served by providing a suitable written notice or warning to the person committing the violation or by administrative action under subsection (c).
A finding of the Secretary under this section shall be set aside only if the finding is found to be unsupported by substantial evidence.
Any person who fails to obey a cease-and-desist order issued under this section after the cease-and-desist order has become final and unappealable, or after the appropriate United States district court has entered a final judgment in favor of the Secretary, shall be subject to a civil penalty assessed by the Secretary, after opportunity for a hearing and for judicial review under the procedures specified in subsections (c) and (d), of not more than $5,000 for each offense. Each day during which the failure continues shall be considered as a separate violation of the cease-and-desist order.
If a person fails to pay an assessment of a civil penalty under this section after the assessment has become a final and unappealable order, or after the appropriate United States district court has entered final judgment in favor of the Secretary, the Secretary shall refer the matter to the Attorney General for recovery of the amount assessed in the district court of the United States for any district in which the person resides or carries on business. In an action for recovery, the validity and appropriateness of the final order imposing the civil penalty shall not be subject to review.
The remedies provided in this subchapter shall be in addition to, and not exclusive of, other remedies that may be available.
