[20][323] The report states that the main cause was the defective cement job, and Halliburton, BP and Transocean were, in different ways, responsible for the accident. [42][43][44] The total estimated volume of leaked oil approximated 4.9Mbbl (210million USgal; 780,000m3) with plus or minus 10% uncertainty,[3] including oil that was collected,[45] making it the world's largest accidental spill. This coalition gained significant influence in the clean-up of the oil spill to try to gain some control over the situation. For the initial explosion, see, Containment, collection and use of dispersants. No flights, except aircraft conducting aerial chemical dispersing operations, or for landing and takeoff, were allowed below 1,000m (3,300ft). Deepwater Horizon Oil Spill Test Results BioWorld is the greatest of all products tested and 96.1% of the initial concentration of oil was degraded by the end of the study. The oil firm alleged failed safety systems and irresponsible behaviour of contractors had led to the explosion, including claims that Halliburton failed to properly use modelling software to analyze safe drilling conditions. Fish and Wildlife Service and the. BP strongly disagreed with the ruling and filed an immediate appeal. Both cores were likely too weak to withstand the pressure because they were composed of a concrete mixture that used nitrogen gas to accelerate curing. [205][206][207][208] According to NOAA, a cetacean Unusual Mortality Event (UME) has been recognized since before the spill began, NOAA is investigating possible contributing factors to the ongoing UME from the Deepwater Horizon spill, with the possibility of eventual criminal charges being filed if the spill is shown to be connected. The Deepwater Horizon oil spill in pictures, https://www.britannica.com/event/Deepwater-Horizon-oil-spill, National Ocean Service - Deepwater Horizon Oil Spill, Deepwater Horizon oil spill of 2010 - Student Encyclopedia (Ages 11 and up), Deepwater Horizon oil spill: debris and oil, Deepwater Horizon oil spill of 2010: path of the oil, National Oceanic and Atmospheric Administration. [286], The petroleum industry claimed that disasters are infrequent and that this spill was an isolated incident and rejected claims of a loss of industry credibility. In addition, Louisiana reported that lost visitor spending through the end of 2010 totaled $32million, and losses through 2013 were expected to total $153million in this state alone. Share sensitive information only on official, secure websites.. On April 20, 2010, the Deepwater Horizon oil rig exploded off the Gulf Coast, killing 11 people and injuring 17. Oil sheencould be seen on the surface of the water covering up to 180 000km2 [3] . [331] The federal judge assigned to the case, Judge Barbier, refused to halt the settlement program, saying he had not seen evidence of widespread fraud, adding that he was "offended by what he saw as attempts to smear the lawyer administering the claims."[332]. [28][361], On 2 July 2015, BP, the U.S. Justice Department and five gulf states announced that the company agreed to pay a record settlement of $18.7billion. This was described as a "sick joke" and "a very serious error of judgement" by Friends of the Earth Scotland. In April 2012, the Justice Department filed the first criminal charge against Kurt Mix, a BP engineer, for obstructing justice by deleting messages showing that BP knew the flow rate was three times higher than initial claims by the company, and knew that "Top Kill" was unlikely to succeed, but claimed otherwise. [347] The settlement includes payments of $2.394billion to the National Fish and Wildlife Foundation, $1.15billion to the Oil Spill Liability Trust Fund, $350million to the National Academy of Sciences for oil spill prevention and response research, $100million to the North America Wetland Conservation Fund, $6million to General Treasury and $525million to the Securities and Exchange Commission. It uses microorganisms or biological agents to treat oil spills, and soils contaminated 4. [318] The report stated that "whether purposeful or not, many of the decisions that BP, Halliburton, and Transocean made that increased the risk of the Macondo blowout clearly saved those companies significant time (and money). [272], On 28 April 2010, the National Energy Board of Canada, which regulates offshore drilling in the Canadian Arctic and along the British Columbia Coast, issued a letter to oil companies asking them to explain their argument against safety rules which require same-season relief wells. At approximately 7:45pm CDT, on 20 April 2010, high-pressure methane gas from the well expanded into the marine riser and rose into the drilling rig, where it ignited and exploded, engulfing the platform. [11][111], The fundamental strategies for addressing the spill were containment, dispersal and removal. Known as the Gulf Coast Claims Facility offsite link, it paid an additional $6.2 billion to more than 220,000 individual and business claimants. Phylogenetic The ever-growing increase in deep-sea oil explorations in the Gulf of Mexico (GoM) has been raising concerns with regard to future oil spills. Deepwater Horizon Oil Spill Crude oil is shown in the Pacific Ocean offshore of Orange County, California, Oct. 3, 2021. "[342][343] The DOJ also said Transocean, the owner and operator of the Deepwater Horizon rig, was guilty of gross negligence as well. This webpage provides information and materials on EPAs enforcement response to the Deepwater Horizon Oil Spill, settlements with several of the defendants, including the record-setting settlement with BP Exploration & Production for an unprecedented $5.5 billion Clean Water Act penalty and up to $8.8 billion in natural resource damages. The gas released caused an enormous underwater explosion that sadly took 11 lives and injured 17 others. As oil spread, did BP battle to contain the media? [citation needed], Prior to the oil spill, on March 31, 2010, Obama ended a ban on oil and gas drilling along the majority of the East Coast of the United States and along the coast of northern Alaska in an effort to win support for an energy and climate bill and to reduce foreign imports of oil and gas. Record criminal fines paid by BP in 2012 half went directly to aid the Gulf. [179][183][184] Some members of Congress criticized the restrictions placed on access by journalists. Corexit EC9500A and Corexit EC9527A were the principal variants. [243][244][245] OSHA said "cleanup workers are receiving "minimal" exposure to airborne toxinsOSHA will require that BP provide certain protective clothing, but not respirators. The Flow Rate Technical Group (FRTG) estimated the initial flow rate was 62,000bbl/d (9,900m3/d). Two main types of affected coast were sandy beaches and marshes. [367] David Rainey, BP's former vice-president for exploration in the Gulf of Mexico, was charged with obstructing Congress by misrepresenting the rate that oil was flowing out of the well. 202-737-3600. service@asmusa.org. It was largely settled when a Federal District judge approved the, That 80 percent resulted in $5.3 billion going to the, The remaining 20 percent, or $1.33 billion, went to, The National Academy of Sciences received $500 million to create the, The National Fish and Wildlife Foundations received $2.544 billion for its, NOAA led development of the preliminary restoration planning, along with the U.S. The Deepwater Horizon spill resulted in the largest natural resource damage assessment ever undertaken. "[309] The investigation by United States Attorney General Eric Holder was announced on 1 June 2010. The Deepwater Horizon accident has brought oil contamination of deep-sea environments to worldwide attention. [302], In July 2013, Hayward was awarded an honorary degree from Robert Gordon University. Deepwater Horizon oil spill. [149], In late 2012, a study from Georgia Tech and Universidad Autonoma de Aguascalientes in Environmental Pollution journal reported that Corexit used during the BP oil spill had increased the toxicity of the oil by 52 times. If it proves to be oil from the subsurface, then that could indicate the possibility of an indefinite release of oil. [36][37] Eleven missing workers were never found despite a three-day U.S. Coast Guard (USCG) search operation and are believed to have died in the explosion. website belongs to an official government organization in the United States. However, it was not clear if this deal had been officially proposed to BP and if BP has accepted it. A study showed that up to 800,000 birds were thought to have died. MOEX Offshore 2007 agreed to pay $45million to the Oil Spill Liability Trust Fund, $25million to five Gulf state and $20million to supplemental environmental projects. As of January2013[update], 935personnel were still involved. Oil is a biological product that can be degraded by microbes, whereas detergents used to clean up oil contaminated sites can make a bad situation even worse. Fortunately, unl [298][299] On 26 July 2010, it was announced that CEO Tony Hayward was to resign and would be replaced by Bob Dudley, who is an American citizen and previously worked for Amoco. If that proves to be the case, the sheen can be expected to eventually disappear. [192] The oil contained approximately 40% methane by weight, compared to about 5% found in typical oil deposits. Diaz also believes neurological disorders should be expected. [335] The firms deny the allegations. [172] All flights in the operations' area were prohibited except flight authorized by air traffic control; routine flights supporting offshore oil operations; federal, state, local and military flight operations supporting spill response; and air ambulance and law enforcement operations. [312], On 8 September 2010, BP released a 193-page report on its web site. This was to cover all offshore cleanup activities, BP later requested a second NIOSH investigation of onshore cleanup operations. Though the leak had slowed, it was estimated by a government-commissioned panel of scientists that 4,900,000 barrels of oil had already leaked into the gulf. The draft plan allocated up to $8.8 billion for restoration from a proposed settlement with BP. BP set up its own private claims program unilaterally in 2010. Although several problems might arise, this is usually the preferred method when indigenous microbes are incapable of degrading hydrocarbon. It was based on our thorough assessment of impacts to the Gulf's natural resources and the services they provide. These traditional techniques are limited in effectiveness and are expensive due to the large area affected by the BP oil spill. These projects allowed restoration of the Gulf to begin immediately. Review of 10 later hospitalizations found that heat exposure and dehydration were consistent findings but could not establish chemical exposure. Natural Resource Damage Assessment (NRDA). [165][168] The delivery method of microbes to oil patches was proposed by the Russian Research and Development Institute of Ecology and the Sustainable Use of Natural Resources. [66] In April 2012, oil was still found along as much as 200mi (320km) of Louisiana coastline and tar balls continued to wash up on the barrier islands. Booms extend 1848in (0.461.22m) above and below the water surface and were effective only in relatively calm and slow-moving waters. 1) The use of dispersants can be harmful to the environment but it is necessary to increase the rate of crude oil degradation by microbes. Because the effects of the Deepwater Horizon spill were so widespread, assessment teams are taking an ecosystem approach to restoring the Gulf ecosystem. When Congress passed the RESTORE Act in 2012, it dedicated 80 percent of all administrative and civil penalties from the responsible parties to ecological and economic recovery efforts in the Gulf.

[41] The oil flowed for 87 days. The Coast Guard said on Oct. 3 that over 5,300 feet of floating barriers, known as booms, had been deployed and that approximately 3,150 gallons of oil had been recovered from the water. [45] According to a group presenting the plaintiffs, the deal has no specific cap. A study based on samples taken at several beaches in the Gulf of Mexico before and after the BP oil spill showed a drastic change in the microbial community at the locations [5]. A finding of gross negligence would result in a four-fold increase in the fines BP would have to pay for violating the federal Clean Water Act, and leave the company liable for punitive damages for private claims. Bacterial community structures were evaluated in oil samples using culture-independent pyrosequencing, including oil mousses collected on sea surface and salt marshes during the Deepwater Horizon oil spill, and oil deposited in sediments adjacent to the wellhead 1 year after the spill. Testing over the past year (2019) reported by GulfSource.org, for the pollutants tested have not produced results.[186]. [4][49] By early June 2010, oil had washed up on 125mi (201km) of Louisiana's coast and along the Mississippi, Florida, and Alabama coastlines. Various risks were identified and evaluated, in particular, that an increase in microbial activity might reduce subsea oxygen levels, threatening fish and other animals. GSF Development Driller II started drilling a second relief on 16 May 2010. [278], On 30 April, President Obama dispatched the Secretaries of the Department of Interior and Homeland Security, as well as the EPA Administrator and NOAA to the Gulf Coast to assess the disaster. Phototrophs and obligated aerobic organisms will be affected due to the lack of light or oxygen respectively. [113] On the most demanding day, 47,849 people were assigned on the response works and over 6,000 Marine vessels, 82 helicopters, and 20 fixed-wing aircraft were involved. When an attempt to employ a top kill, whereby drilling mud was pumped into the well to stanch the flow of oil, also failed, BP in early June turned to an apparatus called the Lower Marine Riser Package (LMRP) cap. [169], On 18 May 2010, BP was designated the lead "Responsible Party" under the Oil Pollution Act of 1990, which meant that BP had operational authority in coordinating the response. Birds were particularly vulnerable to the effects of the Deepwater Horizon oil spill. . Damage Assessment, Remediation, and Restoration Program. 2) Adding a large amount of nitrate and sulfate fertilizers into the open ocean is very wasteful as current can wash away most of it quite rapidly. This is the preferred method when members of the indigenous microbial community are capable of degrading oil [10]. [citation needed] Other studies have reported a variety of mental health issues, skin problems, breathing issues, coughing, and headaches. [59] The Republic of the Marshall Islands Maritime Administrator conducted a separate investigation on the marine casualty. [141] On 24 May, EPA Administrator Lisa P. Jackson ordered EPA to conduct its own evaluation of alternatives and ordered BP to reduce dispersant use by 75%. The Deepwater Horizon oil spill (also referred to as the "BP oil spill") was an industrial disaster that began on 20 April 2010 off of the coast of the United States in the Gulf of Mexico on the BP-operated Macondo Prospect, considered to be the largest marine oil spill in the history of the petroleum industry and estimated to be 8 to 31 percent larger in volume than the previous largest, the . Gerald Baron for Crisisblogger, 8 June 2012. [92] On 19 September 2010, National Incident Commander Thad Allen declared the well "effectively dead" and said that it posed no further threat to the Gulf. [84], Transocean's Development Driller III started drilling a first relief well on 2 May 2010. This oil sheen decreases the amount of sunlight reaching organisms in the water and forms a barrier between the air and water, blocking oxygen and other necessary nutrients from diffusing into the water. The report also states that a central cause of the blowout was failure of a cement barrier allowing hydrocarbons to flow up the wellbore, through the riser and onto the rig, resulting in the blowout. Observe fireboat responding to crews battling the fire during the Deepwater Horizon oil spill of 2010, See how wire entanglement inside a well bore mitigates the effects of blowout preventer failure in an oil well. Official websites use .gov This webpage is limited to EPAs enforcement-related activities only, and does not cover all legal or other actions against BP Exploration & Production and other parties for the spill, such as private party/class action settlements for medical claims and economic damages, or other actions against those responsible for the spill. Connect With ASM. It was largely settled when a Federal District judge approved the largest environmental damage settlement in United States history $20.8 billion on April 4, 2016. Subsurface oil remained offshore and in fine silts. The Gulf Coast Claims Facility and the Deepwater Horizon Litigation: Judicial Regulation of Private Compensation Schemes", Independent Evaluation of the Gulf Coast Claims Facility. On September 17 the bottom kill maneuver was successfully executed through the first relief well. [36][40] The Deepwater Horizon sank on the morning of 22 April 2010. [138] Because the dispersants were applied at depth, much of the oil never rose to the surface. In a New York Times opinion piece, Stephen Teague, staff attorney at the Mississippi Center for Justice, argued that BP had become "increasingly brazen" in "stonewalling payments."

Articles from Britannica Encyclopedias for elementary and high school students. Mixing dispersants with oil at the wellhead would keep some oil below the surface and in theory, allowing microbes to digest the oil before it reached the surface. were used to cleanup after the Deepwater Horizon oil spill. The remaining 20 percent, or $1.33 billion, went to The Oil Spill Liability Trust Fund, a general government fund established in 1986 to aid in oil spill removal and assessment of the damage they have caused. Selective pressure placed upon communities of organisms by the large increase of petroleum and other petroleum derivatives selects for the survival of organisms that can use petroleum and derivatives as energy, electron, and or carbon source [5]. It later emerged through documents released by Wikileaks that a similar incident had occurred on a BP-owned rig in the Caspian Sea in September 2008. [350], In January 2014, a panel of the U.S. Fifth Circuit Court of Appeals rejected an effort by BP to curb payment of what it described as "fictitious" and "absurd" claims to a settlement fund for businesses and persons affected by the oil spill. [80] On 16 June, a second containment system connected directly to the blowout preventer began carrying oil and gas to service vessels, where it was consumed in a clean-burning system. The United States federal government estimated the total discharge at 4,900Mbbl (210million USgal; 780,000m3). "[88] On 4 August 2010, BP began pumping cement from the top, sealing that part of the flow channel permanently. [179] In another example, a CBS News crew was denied access to the oil-covered beaches of the spill area. [216] In December 2013, the journal Environmental Science & Technology published a study finding that of 32 dolphins briefly captured from 24-km stretch near southeastern Louisiana, half were seriously ill or dying. Louisiana will receive more than half the funding, $5 billion, since it saw the most significant damage from the spill. [123], For a time, a group called Matter of Trust, citing insufficient availability of manufactured oil absorption booms, campaigned to encourage hair salons, dog groomers and sheep farmers to donate hair, fur and wool clippings, stuffed in pantyhose or tights, to help contain oil near impacted shores, a technique dating back to the Exxon Valdez disaster. [318] Another was ignoring a pressure test that had failed. [198][212][213] By 2013, over 650 dolphins had been found stranded in the oil spill area, a four-fold increase over the historical average. [157][158] After one week of testing, BP began to proceed[159] and by 28 June, had removed 890,000bbl (141,000m3).
