The Act to Prevent Pollution From Ships was signed on October 21, 1980. The NOAA states, "Mandated in 1983, this act gives the USCG the authority to develop regulations and enforce MARPOL Annex V, including the discharge of garbage and plastics from ships. The act applies to all U.S. flag ships anywhere in the world and to all foreign flag vessels operating in navigable U.S. waters or while at a port or terminal under U.S. jurisdiction. The act also establishes regulations for operational discharges and dumping of wastes from vessels."
