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):
NEPCO 140 oil spill and national volunteers for months. Clean-up of the oil was accomplished primarily by intensive hand labor, through power-washing shorelines and hand cutting and hauling contaminated underwater and marsh vegetation. The clean-up was terminated on October 22, 1976; 122 days after the spill. However, many areas with oil contamination were not cleaned-up and the oil was left to degrade naturally. The United States alleged it spent $8,062,981 to clean its territorial waters and reimbursed Canada, pursuant to an executive agreement for their $768,265 spent.<ref name="http://bulk.resource.org/courts.gov/c/F2/664/664.F2d.327.81-6084.1608.html"></ref> NEPCO 140 oil spill The NEPCO 140 Oil Spill took place in 1976 near Clayton, New
