Oil spill governance in the United States debates is illustrated in the question "who is liable in the case of a vessel spill?" The cargo owner or the ship operator/ owner? Another significant issue was the interaction of domestic legislation and international measures. In 1980's, international agreements being considered would take over oil spills federal and state laws adding further complexity to party liability. However, after the "Exxon Valdez" incident, the short comings of the patchy framework for oil spill governance was apparent and growing pressure placed on lawmakers resulted in the establishment of the more comprehensive Oil Pollution Act of 1990. The Oil Pollution Act (1990):
Prestige oil spill a rupture and quickly release much of the remaining oil and create another catastrophic spill. The report urged the government to take "prompt" action. Experts predicted marine life could suffer from the pollution for at least ten years due to the type of oil spill, which contained light fractions with polyaromatic hydrocarbons and could poison plankton, fish eggs and crustaceans with carcinogenic effects in fish and potentially humans as well. In the subsequent months, thousands of volunteers joined the public company TRAGSA (the firm chosen by the regional government to deal with the cleanup) to help clean the affected coastline.
