The Exxon Valdez Oil Spill was one of the largest manmade environmental disasters ever to occur at sea, seriously affecting plants and wildlife. Its remote location (accessible only by helicopter and boat) made government and industry response efforts difficult, and severely taxed existing plans for response. The region is a habitat for salmon, sea otters, seals, and sea birds.

During the first few days of the spill, heavy sheens of oil, such as the sheen visible in this photograph, covered large areas of the surface of Prince William Sound.

. A private company applied dispersant 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.

Working with the U.S. Coast Guard, which officially led the response, Exxon mounted a cleanup effort that exceeded in cost, scope and thoroughness any previous oil spill cleanup. More than 11,000 Alaska residents, along with many Exxon employees, worked throughout the region to help restore the environment. Exxon later released "Scientists and the Alaska Oil Spill," a video carrying the label "A Video for Students" that was given to schools and is reported of being highly distorting in how it shows the clean-up process.

According to several studies funded by the state of Alaska, the spill had a range of short and long term economic impacts. These included the loss of recreational sports fisheries, reduced tourism, and an estimate of what economists call "existence value," which is the value to the public of a pristine Prince William Sound.

In 1992, the Coast Guard declared the cleanup complete and commended Exxon for its unprecedented effort. (Exxon spent approximately $2 billion during the clean up effort.)

However, after 18 years many animals are still recovering from this disaster.

Litigation

In 1994, in the case of Baker vs. Exxon, an Anchorage jury awarded $287 million for actual damages and $5 billion for punitive damages. The punitive damages amount was based on a single year's profit by Exxon at that time.

Exxon appealed the ruling and the 9th U.S. Circuit Court of Appeals ordered the original judge, Russel Holland, to reduce the punitive damages. On December 6, 2002, the judge announced that he had reduced the damages to $4 billion, which he concluded was justified by the facts of the case and was not grossly excessive.

Exxon appealed again, sending the case back to court to be considered in regard to a recent Supreme Court ruling in a similar case, which caused Judge Holland to increase the punitive damages to $4.5 billion, plus interest.

After more appeals, and oral arguments heard by the 9th Circuit Appellate Court on January 27, 2006, the damages award was cut to $2.5 billion on December 22, 2006. The court cited recent U.S. Supreme Court rulings relative to limits on punitive damages.

Exxon appealed again. On May 23, 2007, the Ninth U.S. Circuit Court of Appeals denied Exxon Mobil Corp.'s request for another hearing, letting stand its ruling that Exxon owes $2.5 billion in punitive damages. Exxon's only further option for appeal is the U.S. Supreme Court. Exxon has said it will make this final appeal.

Exxon's official position is that punitive damages greater than $25 million are not justified because the spill resulted from an accident, and because Exxon spent an estimated $2 billion cleaning up the spill, along with a further $1 billion to settle civil and criminal charges related to the case. Attorneys for the plaintiffs contended that Exxon bore responsibility for the accident because the company "put a drunk in charge of a tanker in Prince William Sound."

Exxon recovered a significant portion of clean-up and legal expenses through insurance claims and tax deductions for the loss of the Valdez. Also, in 1991, Exxon made a separate financial settlement with a group of seafood producers known as the Seattle Seven for the disaster's impact on the Alaskan seafood industry. The agreement granted $63.75 million to the Seattle Seven but stipulated that the seafood companies would have to repay almost all of any punitive damages to Exxon.

Ship

In the aftermath of the Exxon Valdez incident, the U.S. Congress passed the Oil Pollution Act of 1990, including a clause prohibiting vessels that had caused oil spills of more than 1 million US gallons (3,800 m³). In April 1998, the company argued in a legal action against the U.S. 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 Oil Pollution Act also set a schedule for the gradual phase in of a double-hull design, providing an additional layer between the oil tanks and the ocean. While a double hull would likely not have prevented the Valdez disaster, a Coast Guard study estimated that it would have cut the amount of oil spilled by 60 percent.

The Exxon Valdez supertanker was towed to San Diego, arriving on July 10 and repairs began in July 30, 1989. Approximately 1,600 tons of steel were removed and replaced. In June 1990 the tanker, renamed SeaRiver Mediterranean, left harbor after $30 million of repairs.

Environmental impact

Wildlife was severely affected by the oil spill

Both the long and short-term effects of the oil spill have been studied comprehensively. Thousands of animals died immediately; the best estimates include 250,000 - 500,000 seabirds, 2,800 - 5,000 sea otters, approximately 12 river otters, 300 harbour seals, 250 bald eagles, and 22 orcas, as well as the destruction of billions of salmon and herring eggs. Due to a thorough cleanup, little visual evidence of the event remained in areas frequented by humans just one year later, but the effects of the spill continue to be felt today. In the long term, reductions in population have been seen in various ocean animals, including stunted growth in pink salmon populations. Sea otters and ducks also showed higher death rates in following years, partly because they ingested contaminated creatures. Many animals were also exposed to oil when they dug up their prey in dirty soil. Researchers said some shoreline habitats, such as contaminated mussel beds, could take up to 30 years to recover. While it will take years for a solid long term study, some interim effects have already been noted. Rockweed is once again growing on boulders where the spill occurred, though pink salmon harvests have varied in the years since the spill.

Other impacts

The Oil, Chemical, and Atomic Workers Union, representing approximately 40,000 workers nationwide, announced opposition to drilling in the Arctic National Wildlife Refuge (ANWR) until Congress enacted a comprehensive national energy policy. In the aftermath of the spill, Alaska governor Steve Cowper issued an executive order requiring two tugboats to escort every loaded tanker from Valdez out through Prince William Sound to Hinchinbrook Entrance. As the plan evolved in the 1990s, one of the two routine tugboats was replaced with a 210 foot (64 m) Escort Response Vehicle (ERV). The majority of tankers at Valdez are still single-hulled, but Congress has enacted legislation requiring all tankers to be double-hulled by 2015.
