Authorizes the Secretary to: (1) assess a civil penalty for violations of this Act; and (2) remove a barge that has been abandoned. Declares that the United States shall not be liable for damages resulting from such removal. Makes the owner or operator of an abandoned barge liable for expenses incurred by the United States in removing it. Declares that barge removal contractors and subcontractors are not liable for damages resulting from such removal, except in certain circumstances.
