The procedures and rules contained in this subpart prescribe the administrative process that will be applied with respect to a determination to assess civil money penalties, debar, or increase the amount of a surety bond and which may be applied to the enforcement of provisions of the work contract, or obligations under 8 U.S.C. 1188 , 20 CFR part 655 , subpart B, or this part, or to the collection of monetary relief due as a result of any violation. Except with respect to the imposition of civil money penalties, debarment, or an increase in the amount of a surety bond, the Secretary may, in the Secretary's discretion, seek enforcement action in a District Court of the United States without resort to any administrative proceedings.
