Exxon Valdez oil spillThe Exxon Valdez oil spill was an " title="Oil spill">oil spill, involving the " title="Exxon Valdez">Exxon Valdez, on " title="March 24">March 24 " title="1989">1989.
The Exxon Valdez, an " title="Oil">oil " title="Tanker">tanker, was departing from the " title="Valdez oil terminal">Valdez oil terminal (on its 28th voyage) and heading south, through " title="Prince William Sound">Prince William Sound, with a full load of " title="Oil">oil. Captain Joseph Hazelwood radioed to the " title="United States Coast Guard">Coast Guard station that he would be changing course in order to avoid some growlers, small icebergs which had drifted into the sound from the Columbia Glacier. The captain received permission to move into the northbound lane. Before retiring to his cabin, Captain Hazelwood instructed his third mate Gregory Cousins to steer the vessel back into the southbound lane once it passed Busby Island. Although Cousins did give the instructions to the helmsman to steer the vessel to the right, the vessel was not turning sharply enough and at 12:04 a.m. the vessel hit Bligh Reef. It is not known whether Cousins gave the orders too late, the helmsman did not follow instructions properly, or if something was wrong with the steering system of the vessel. Journalist " title="Greg Palast">Greg Palast has argued that the accident was due to a " title="Corporation">corporate decision to maintain the ship's Raycas " title="Radar">radar off in order to save money. Palast contends that the ship had been running without radar for at least a year. About 11 million " title="Gallon">gallons of " title="Crude oil">crude oil were spilled, affecting 1,900 " title="Kilometre">km of " title="Coast">coastline.
The spill was the largest in " title="History of the United States">U.S. history, and its remote location (accessible only by helicopter and boat) made government and industry response efforts difficult and tested existing plans for dealing with such an event. The region was " title="Habitat">habitat for " title="Salmon">salmon, sea otters, " title="Pinniped">sealss, and sea " title="Bird">birds.
A trial burn was conducted during the early stages of the spill, in a region of the spill isolated from the rest by a fire-resistant boom. The test was relatively successful, but because of unfavorable weather no additional burning was attempted in this cleanup effort. Mechanical cleanup was started shortly afterward using booms and skimmers, but the skimmers were not readily available during the first 24 hours following the spill and thick oil and " title="Kelp">kelp tended to clog the equipment. Transferring oil from temporary storage vessels into more permanent containers was also difficult because of the oil's weight and thickness. In addition, a trial application of dispersants was performed. The use of dispersants proved to be controversial. Less than 4,000 gallons of dispersant were available in Valdez, Alaska, and no application equipment or aircraft. A private company applied dispersants on March 24 with a helicopter and dispersant bucket. Because there was not enough wave action to mix the dispersant with the oil in the water, their use was discontinued.
In the aftermath of the Exxon Valdez incident " title="United States Congress">Congress passed the Oil Pollution Act of 1990, including a clause banning the Exxon Valdez from Alaskan waters. Exxon spent some 2 billion dollars cleaning up the spill with 11,000 workers, and a further 1 billion to settle civil and criminal charges related to the case. A lawsuit brought by fishermen, property owners, businesses and communities who claimed they were harmed by the spill is still in progress as of " title="2002">2002. An award of $287 million for actual damage and $5000 million for " title="Punitive damages">punitive damages was awarded by an " title="Anchorage, Alaska">Anchorage jury in " title="1994">1994. Exxon appealed the ruling and the 9th U.S. Circuit Court of Appeals ordered the original judge Russel Holland to reduce the amount. On " title="December 6">December 6, " title="2002">2002 the judge announced that he had reduced the damages to $4000 million, which he concluded was justified by the facts of the case and not grossly excessive. Exxon's company position is that no punitive damages are justified because the spill was an accident. However in court it was argued that allowing a "known drunk" to captain the ship was reprehensible. Exxon has said it will continue to appeal.
The tanker was towed to " title="San Diego, California">San Diego, arriving on " title="July 10">July 10 and repairs began in " title="July 30">July 30, 1989. Around 1,600 tons of steel was removed and replaced. In June " title="1990">1990 the renamed SeaRiver Mediterranean left harbor after $30 million of repairs. The ship was banned from Valdez by a new regulation that prohibited vessels that had caused oil spils of more than 1 million gallons. In April " title="1998">1998 the company argued in a legal action against government that the ship should be allowed back to Valdez, since the regulation was unfairly directed at Exxon alone (no other ships meet this criterion.)
The long-term effects of the oil spill have been studied. Thousands of animals perished immediately, the best estimates are: 250,000 sea birds, 2,800 sea otters, 300 harbor seals, 250 bald eagles, up to 22 killer whales, and billions of salmon and herring eggs. Though even as soon as a year later, one had to look carefully on most beaches to find any evidence of the spill. In the long term, declines have been observed in various marine populations, including stunted growth and indirect mortality increases in pink salmon populations. Sea otters and ducks also showed higher death rates years later, partly because they ate contaminated invertebrates. The animals also were exposed to oil when they dug up their prey in tainted soil Researchers said some shoreline habitats, such as contaminated mussel beds, could take up to 30 years to recover.
On " title="January 29">January 29, " title="1990">1990 the trial of captain Joseph Hazelwood began in " title="Anchorage, Alaska">Anchorage, Alaska. Then on " title="March 13">March 13, " title="1991">1991 the " title="United States Department of Justice">United States Justice Department annouced that Exxon had agreed to pay $1 billion for the clean-up of the spill (Exxon in fact would end-up spending about $2 billion on the clean-up).
Exxon spent some $2 billion cleaning up the spill, most of this paid by insurance. Exxon has also paid damages of $50,000,000 from an insurance fund.
According to reports from the " title="Survivors of the Valdez Oil Spill">Survivors of the Valdez Oil Spill, Exxon has earned approximately 800 million dollars a year on the money set aside to pay the damages, which as of " title="2001">2001, equalled $6 billion dollars, more than enough to pay the damage award without impacting the financial standing of the company.
