Revised sectionSource section (U.S. Code) 371646:391a(18) section 3716 requires the Secretary to establish effective control and supervisory measures to prohibit the discharge of tank washings by dumping at sea. The section also prohibits the dumping vessel from subsequently loading any cargo at a port or terminal subject to the jurisdiction of the United States. This section is intended to prohibit the practice of discharging a cargo of oil or hazardous substance, then going to sea to clean tanks by pumping tank washing mixtures overboard, and then returning to a port or terminal subject to the jurisdiction of the United States for the purpose of loading a cargo that was incompatible with the prior cargo.
