Because there was not enough wave action to mix the dispersant with the oil in the water, the Coast Guard representatives at the site concluded that the dispersants were not working and so their use was discontinued. Dispersants are chemicals that are sprayed on a surface oil slick to break down the oil into smaller droplets that more readily mix with the water. Exxon declared that burning was no longer a viable response option. But if you see something that doesn't look right, click here to contact us! The lingering of oil from the 1989 Exxon Valdez oil spill (EVOS) in some of the Prince William Sound (PWS) beaches, Alaska poses a scientific challenge, because various studies expected the oil. certain bacteria and fungi) are capable of facilitating the biodegradation of oil. [29] Immediate effects include the deaths of between 100,000 and 250,000 seabirds, at least 2,800 sea otters, approximately 12 river otters, 300 harbor seals, 247 bald eagles, and 22 orcas, and an unknown number of salmon and herring.

The damaged oil tanker Exxon Valdez, towed out of Alaska's Prince William Sound by a tugboat and a U.S. Coast Guard Cutter, on June 23, 1989. EPA specialists in the use of experimental bioremediation technologies assisted in the spill cleanup and the National Oceanic and Atmospheric Administration at NOAA was involved in providing weather forecasts for Prince William Sound, allowing the cleanup team to adapt their methods to changing weather conditions. The Exxon Valdez disaster led to the examination of oil spill prevention rules and regulations in the US. At around midnight on March 24 Cousins began to maneuver the vessel into the traffic lanes. What was done to contain the Exxon Valdez oil spill? Exxon Valdez, an oil supertanker owned by Exxon Shipping Company bound for Long Beach, California struck Prince William Sound 's Bligh Reef, 1.5 mi (2.4 km) west of Tatitlek, Alaska at 12:04 a.m. and spilled 10.8 million US gallons (257,000 bbl) (or 37,000 tonnes) [1] of crude oil over the next few days. [75], Several weeks after the spill, Saturday Night Live aired a pointed sketch featuring Kevin Nealon, Phil Hartman, and Victoria Jackson as cleanup workers struggling to scrub the oil off of animals and rocks on a beach in Prince William Sound.[76]. The ecologically sensitive location, season of the year, and large scale of this spill resulted in one of the largest environmental disasters in U.S. history. On December 6, 2002, Holland announced that he had reduced the damages to $4billion, which he concluded was justified by the facts of the case and was not grossly excessive. Now, Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, takes a look at the lessons scientists are learning from these . Animal rescue . a representative from the Alaska Department of Environmental Conservation, Some of the methods tried to clean up the oil were: burning, mechanical cleaning, and chemical dispersants. It was later [53][54], As of December 15, 2009, Exxon had paid the entire $507.5million in punitive damages, including lawsuit costs, plus interest, which were further distributed to thousands of plaintiffs.

In the letter, he stated that '[it] appears that the Vikoma boom and/or deployment vessels used may not be adequate to handle the harsh environmental conditions of Port Valdez'[28]. Katrina was said to have knocked out 95% of oil production in the Gulf, which is a key supplier for the U.S. economy. dispersants was performed. abilities of local, national, and industrial organizations to prepare for, and Adequate resources for this task did not reach the accident scene quickly trial phases. Shortly after the spill, mechanical cleanup was started using booms and This incident has become one of the greatest environmental disasters of the entire generation caused by human error. Exxon Valdez was a single-hulled tanker; a double-hull design, by making it less likely that a collision would have spilled oil, might have prevented the Exxon Valdez disaster.

Investigators later learned that Joseph Hazelwood, the captain of Exxon Valdez, had been drinking at the time and had allowed an unlicensed third mate to steer the massive ship. The third mate advised traffic control and decided to deviate from the predetermined traffic lane to avoid small icebergs; a common occurrence since the Columbia Glacier calved such icebergs nearby. Cousins called the Captain back to the bridge, and Hazelwood spent 15 to 20 minutes trying to back off the Bligh Reef to no avail. For more information, please see History: Exxon Valdez Oil Spill.

Exxon was widely criticized for its slow response to cleaning up the disaster and John Devens, the mayor of Valdez, said his community felt betrayed by Exxon's inadequate response to the crisis. He was convicted of misdemeanor negligent discharge of oil. A fire-resistant boom was placed on tow lines, and two ends of the boom were each attached to a ship. On 24 March 1989, the Exxon Valdez ran aground on Bligh Reef in Prince William Sound. dispersant available in its terminal in Valdez, and no application equipment or discontinued. The two ships with the boom between them moved slowly throughout the main portion of the slick until the boom was full of oil. Environmental activists and State officials became concerned that BP would use similar techniques to minimize liability and de-emphasize health impacts: the symptoms being reported in the Gulf states are the same ones that hit workers in Alaska. DR AYUB MD. dispersants proved to be controversial. Efforts to save sensitive areas were begun early in the cleanup. [44], Meanwhile, Exxon appealed the ruling, and the 9th U.S. In August 2012, she was beached at Dalian, China, and dismantled.

Scientists have returned to Mearns Rock every summer since the spill to photograph the plants and small critters growing on it. [45], After more appeals, in December 2006 the damages award was cut to $2.5billion. A private company applied dispersants on March 24, with a helicopter Eschewing sustainable agricultural practices, such as crop rotation, they managed to reap read more, John D. Rockefeller (1839-1937), founder of the Standard Oil Company, became one of the worlds wealthiest men and a major philanthropist. The spill was the largest in U.S. history and tested the They also reiterated the claim that the Coast Guard had delayed cleanup by refusing to give permission to immediately use chemical dispersants on the spill. One of those areas that was oiled but never cleaned is a large shoreline boulder called Mearns Rock. Guard to strengthen its regulations on oil tank vessels and oil tank owners 1990, which required the Coast [37] Federal scientists estimate that between 16,000 and 21,000 US gallons (61 to 79 m3) of oil remains on beaches in Prince William Sound and up to 450 miles (725km) away. Though this oil . They found that many of the mussels, barnacles and various seaweeds growing on the rock before the spill returned to normal levels about three to four years after the spill. However, this also displaced and destroyed the microbial populations on the shoreline; many of these organisms (e.g. 250,000 barrels of crude (or 10.8 million gallons) were released into the Gulf of Alaska after the oil tanker Exxon. Three methods were tried in the effort to clean up the spill: A trial burn was conducted during the early stages of the spill. At the helm, the third mate may never have collided with Bligh Reef had he looked at his RAYCAS radar. While a double hull would likely not have prevented the Exxon Valdez disaster, a Coast Guard study estimated that it would have cut the amount of oil spilled by 60 percent. teleconference, and the The Exxon Valdez oil spill was a manmade disaster that occurred when Exxon Valdez, an oil tanker owned by the Exxon Shipping Company, spilled 11 million gallons of crude oil into Alaska's. was applied the same day as the spill by helicopter, but because of little Exxon Valdez oil tanker ran aground on Bligh Reef Spilled 11 million gallons of oil into the Prince William Sound, Alaska . The impact of the collision tore open the ships hull, causing some 11 million gallons of crude oil to spill into the water. Through direct contact with oil or because of a loss of food The ship, Exxon Valdezfirst commissioned in 1986was repaired and returned to service a year after the spill in a different ocean and under a different name. Nearly 30 years later, pockets of crude oil remain in some locations. . Both long-term and short-term effects of the oil spill have been studied. Despite the extensive cleanup attempts, less than ten percent of the oil was recovered. Seal pupping locations and fish hatcheries were given the highest importance, and for these areas special cleaning techniques were approved. The Exxon Valdez was a huge tanker, a ship built to carry large amounts of oil. In addition, a trial application of dispersants were the only viable option left, however they were still in the [3][4] Prince William Sound's remote location, accessible only by helicopter, plane, or boat, made government and industry response efforts difficult and made existing response plans especially hard to implement. Today, 20 years after the largest spill in U.S. waters, the oil that gushed from the hull of the Exxon Valdez is still having effects. [39], In October 1989, Exxon filed a suit against the State of Alaska, claiming that the state had interfered with Exxon's attempts to clean up the spill by refusing to approve the use of dispersant chemicals until the night of the 26th.

The single-hulled ship could no longer transport oil in U.S. waters, due to the new regulations. Exxon Valdez laid to rest; Nature. Because there was not enough wave action to mix the Chemical dispersants can be successful in cleaning up oil spills. Because Prince William Sound contained many rocky coves where the oil was collected, the decision was made to displace it with high-pressure hot water. "The oil mixes with seawater and forms an emulsionLeft out, the surface crusts over but the inside still has the consistency of mayonnaise or mousse. The National Research Council issued a report in 1989 that recommended chemical dispersants be considered as a first response option to oil spills. Exxon claimed OPA was effectively a bill of attainder, a regulation that was unfairly directed at Exxon alone. The iron and steel industry spawned new construction materials, the railroads connected the country and the discovery of oil provided a new source of fuel. cleanup team to adapt their methods to changing weather conditions. This factor was certainly critical to the extent and subsequent cost of the Exxon Valdez oil spill cleanup. The dispersants were controversial, and it was unclear if they would work or cause even more harm. read more, The NASA space shuttle Challenger exploded on January 28, 1986, just 73 seconds after liftoff, bringing a devastating end to the spacecrafts 10th mission. The local villagers had to cope with a tripling of their population from 80 to 250. The two ships with the boom between them moved slowly The vessel was traveling outside normal shipping lanes in an attempt to avoid ice. facility to clean oil from otters, and the International Bird Research Center "[3][24][25], According to a report by David Kirby for TakePart, the main component of the Corexit formulation used during cleanup, 2-butoxyethanol, was identified as "one of the agents that caused liver, kidney, lung, nervous system, and blood disorders among cleanup crews in Alaska following the 1989 Exxon Valdez spill.[26]. Shortly after the spill, mechanical cleanup was started using booms and skimmers. A USGS scientist who analyses the remaining oil along the coastline states that it remains among rocks and between tide marks. A fire-resistant boom was placed on tow lines, and two ends of the boom were each attached to a ship. Eleven million gallons of oil leaked, unstopped, from the ship when it hit rocks in 1989. slow. Dispersants are chemicals that are applied to the surface of the water, usually by a low-flying plane. On a cold March night in 1989, the tanker Exxon Valdez ran aground off the coast of Alaska, spilling 11 million gallons of crude oil into the waters of Prince William Sound and creating one of. Dispersants work much like the detergent soap that you use to clean grease from your dishes (but dispersants are less toxic). Repairs to damaged skimmers were time consuming. "[49] The punitive damages were further reduced to an amount of $507.5million. The dispersant Cortex 9580 That's unquestionably the case as we approach the 29 th anniversary of the disastrous Exxon Valdez oil spill. [65], According to several studies funded by the state of Alaska, the spill had both short-term and long-term economic effects. wildlife rescue was Through direct contact with oil or because of a loss of food resources, many birds and mammals died. AP Photo The cause of the oil spill dates back in Alaska 1989 when the Exxon Valdez, an oil supertanker, stuck Bligh Reef in Prince William Sound. The legislation included a clause that prohibits any vessel that, after March 22, 1989, has caused an oil spill of more than 1million US gallons (3,800m3) in any marine area, from operating in Prince William Sound. The two ships with the boom between them moved slowly throughout the main portion of the slick until the boom was full of oil. Scientists who have monitored the spill area for the last 25 years report that concern remains for one of two pods of local orca whales, with fears that one pod may eventually die out. Five years ago this week, engineers stopped the Deepwater Horizon (DWH) oil spill the largest one in U.S. history, easily displacing the Exxon Valdez spill from the top spot. Since the incident occurred in open navigable waters, the U.S. Coast Guard's On-Scene Coordinator had authority for all activities related to the cleanup effort. A controversial method that was used by the companies to clean up the Exxon Valdez oil spill was to use chemical dispersants, which theoretically would break down the oil and, therefore, allow . traffic. dispersant in their body at dangerously high concentrations. The company converted the old oil tanker to an ore carrier, renaming it the Dong Feng Ocean. The company claimed that the Coast Guard was "wholly or partially responsible" for the spill, because they had granted mariners' licenses to the crew of the Valdez, and because they had given Exxon Valdez permission to leave regular shipping lanes to avoid ice. [50] The Court's ruling was that maritime punitive damages should not exceed the compensatory damages,[50] supported by a precedent dating from 1818. burning nor the mechanical cleanup was truly effective in cleaning the oil, so enough.
