API announced the creation of an offshore safety institute, separate from API's lobbying operation. [268][269] Later a six-month offshore drilling (below 500ft (150m) of water) moratorium was enforced by the United States Department of the Interior. Anthony Badalementi was sentenced to one year probation,[369] Donald Vidrine paid a $50,000 fine and received 10 months probation,[370] Kurt Mix received 6 months' probation,[371] and David Rainey and Robert Kaluza were acquitted. [197] A study of insect populations in the coastal marshes affected by the spill also found a significant impact. He described BP's actions as "reckless." If that proves to be the case, the sheen can be expected to eventually disappear. Bacteria that had adapted to consuming naturally occurring gas and oil seeping from the seabed were thought to have consumed a portion of it. Share sensitive information only on official, secure websites. 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]. The study was published in the April 2016 Diseases of Aquatic Organisms. 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. 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." [31] Built by South Korean company Hyundai Heavy Industries[32] and owned by Transocean, the rig operated under the Marshallese flag of convenience, and was chartered to BP from March 2008 to September 2013. The goal of the $500 million, 10-year research initiative, known as the Gulf of Mexico Research Initiative offsite link (GoMRI), is to improve understanding of spill events and associated environmental stresses and public health implications. [252], A cohort study of almost 2,200 Louisiana women found "high physical/environmental exposure was significantly associated with all 13 of the physical health symptoms surveyed, with the strongest associations for burning in nose, throat or lungs; sore throat; dizziness and wheezing. What resulted from this one incident was an economic, political, scientific and legal nightmare. Not only was BP required to pay both criminal and civil court ordered penalties of more than $20.8 billion, they funded $500 million in additional research in 2010. In the November 2012 resolution of the federal charges against it, BP agreed to plead guilty to 11 felony counts related to the deaths of the 11 workers and paid a $4billion fine. Women who suffered a high degree of economic disruption as a result of spill were significantly more likely to report wheezing; headaches; watery, burning, itchy eyes and stuffy, itchy, runny nose. 2. [227], A 2014 bluefin tuna study in Science found that oil already broken down by wave action and chemical dispersants was more toxic than fresh oil. Two methods of bioremediation were used: bioaugmentation and biostimulation [11] . In both oil. The parents reported "unexplained symptoms among their children, including bleeding ears, nose bleeds, and the early start of menstruation among girls," according to David Abramson, director of Columbia University's National Center for Disaster Preparedness. [153] It is calculated that about 5% of leaked oil was burned at the surface and 3% was skimmed. Efforts in May to place a containment dome over the largest leak in the broken riser were thwarted by the buoyant action of gas hydratesgas molecules in an ice matrixformed by the reaction of natural gas and cold water. [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. $1 billion already allocated during early restoration which began in 2011. The British Petroleum oil spill (BP oil spill), also known as the Deepwater Horizon oil spill, is the largest oil spill in the history of the petroleum production industry [11] . The Deepwater Horizon oil spill that occurred in 2010 was one of the most devastating oil spills in history.

[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. The settlement ended all civil and criminal penalty claims against the owners and operators of the rig BP, Anadarko, TransOcean and Halliburton under the Clean Water Act and the Oil Pollution Act. Secure .gov websites use HTTPS [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. [129] Dispersant and PAHs from oil are believed to have caused "disturbing numbers" of mutated fish that scientists and commercial fishers saw in 2012, including 50% of shrimp found lacking eyes and eye sockets. [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. [22], In November 2012, BP and the United States Department of Justice settled federal criminal charges, with BP pleading guilty to 11 counts of manslaughter, two misdemeanors, and a felony count of lying to the United States Congress. The devastating environmental impacts of the Exxon Valdez spill in 1989 and its media notoriety made it a frequent comparison to the BP Deepwater Horizon spill in the popular press in 2010, even though the nature of the two spills and the environments impacted were vastly different. Pre-oil spill samples are what someone would expect in other beaches of similar location without contamination, which include a variety of diverse organisms that exhibit high level of interactions [5]. [281], Public opinion polls in the U.S. were generally critical of the way President Obama and the federal government handled the disaster and they were extremely critical of BPs response. The Deepwater Horizon oil spill began on April 20, 2010, when an explosion damaged the Deepwater Horizon oil rig. In early July the LMRP cap was removed for several days so that a more permanent seal could be installed; this capping stack was in place by July 12. Two methods of bioremediation were used: bioaugmentation and biostimulation [11]. [58] As of December2012[update], 339mi (546km) of coastline remain subject to evaluation and/or cleanup operations. [139][140] On 20 May, BP determined that none of the alternative products met all three criteria of availability, non-toxicity and effectiveness. According to BP and the USCG, it is "not oil and it's not harmful. [59], On 25 July 2013, Halliburton pleaded guilty to destruction of critical evidence after the oil spill and said it would pay the maximum allowable fine of $200,000 and will be subject to three years of probation. A decrease in the number of phototrophs, with them being primary producers in marine food chain will greatly impact all other organisms. BP also agreed to four years of government monitoring of its safety practices and ethics, and the Environmental Protection Agency announced that BP would be temporarily banned from new contracts with the United States government. Corexit EC9500A and Corexit EC9527A were the principal variants. Marine mammals such as dolphins, whales, and seals are also greatly affected by this horrific event. The effect of the microscopic oil droplets on the ecosystem was unknown, though their presence, along with that of a layer of oil several inches thick discovered on portions of the seafloor in September, cast doubt on earlier predictions about the speed with which the discharged oil would dissipate. BP said the report was inconclusive as to any causation associated with the spill. They used this assessment to develop a science-based, comprehensive restoration plan for the Gulf of Mexico, which will be funded through a settlement with BP for up to $8.8 billion. [47][48] The company argued that government figures do not reflect over 810,000bbl (34million USgal; 129,000m3) of oil that was collected or burned before it could enter the Gulf waters. Articles from Britannica Encyclopedias for elementary and high school students. This is the preferred method when members of the indigenous microbial community are capable of degrading oil [10]. Certain techniques described above such as low-pressure flushing and vacuum pumping can disrupt and cause long term damage to sensitive microbial environments such as marshes and wetlands [3]. "[296] BP's chief operating officer Doug Suttles contradicted the underwater plume discussion noting, "It may be down to how you define what a plume is here The oil that has been found is in very minute quantities. [342][344], On 14 November 2012, BP and the US Department of Justice reached a settlement. Tests for chemical exposure in the seven fishermen were negative; NIOSH concluded that the hospitalizations were most likely a result of heat, fatigue, and terpenes that were being used to clean the decks. Let us know if you have suggestions to improve this article (requires login). [127][128][129], A 2011 analysis conducted by Earthjustice and Toxipedia showed that the dispersant could contain cancer-causing agents, hazardous toxins and endocrine-disrupting chemicals. [116] Booms were criticized for washing up on the shore with the oil, allowing oil to escape above or below the boom, and for ineffectiveness in more than three- to four-foot (90120cm) waves. A final device was created to attach a chamber of larger diameter than the flowing pipe with a flange that bolted to the top of the blowout preventer and a manual valve set to close off the flow once attached. On April 4, 2016, the court approved a settlement with BP for natural resource injuries stemming from the spill. [57] As of July2011[update], about 491mi (790km) of coastline in Louisiana, Mississippi, Alabama and Florida were contaminated by oil and a total of 1,074mi (1,728km) had been oiled since the spill began. Academy Directory. The first one is increasing the surface area through emulsification. [116], Dispersants are said to facilitate the digestion of the oil by microbes. The plan was criticised for its expense and poor results. In March 2014, BP was again allowed to bid for oil and gas leases. environmental disaster, Gulf of Mexico [2010]. [61] [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. Connect With ASM. Two main types of affected coast were sandy beaches and marshes. Get a Britannica Premium subscription and gain access to exclusive content. The explosion, which killed 11 men, caused the rig to sink and started a catastrophic oil leak from the well. 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. A lock (LockA locked padlock) or https:// means youve safely connected to the .gov website. 4) Is there a way to isolate the genes responsible for oil degrading microbes and introduce them to indigenous microbe populations that are incapable of oil degrading? [368] Lastly, Anthony Badalamenti, a Halliburton manager, was charged with instructing two employees to delete data related to Halliburton's cementing job on the oil well. Official websites use .gov The goal of the $500 million, 10-year research initiative, known as, Gulf Coast Ecosystem Restoration Trust Fund, Transocean plead guilty to criminal charges, Detailed allocations and project information, North American Wetlands Conservation Fund. Rather, it concluded that "notwithstanding these inherent risks, the accident of April 20 was avoidable" and that "it resulted from clear mistakes made in the first instance by BP, Halliburton and Transocean, and by government officials who, relying too much on industry's assertions of the safety of their operations, failed to create and apply a program of regulatory oversight that would have properly minimized the risk of deepwater drilling. The Deepwater Horizon rig, owned and operated by offshore-oil-drilling company Transocean and leased by oil company BP, was situated in the Macondo oil prospect in the Mississippi Canyon, a valley in the continental shelf. [136] The two formulations are neither the least toxic, nor the most effective, among EPA's approved dispersants, but BP said it chose to use Corexit because it was available the week of the rig explosion. By that time cleanup had cost BP over $14billion. As of January2013[update], 935personnel were still involved. [67] In 2013, some scientists at the Gulf of Mexico Oil Spill and Ecosystem Science Conference said that as much as one-third of the oil may have mixed with deep ocean sediments, where it risks damage to ecosystems and commercial fisheries. [81] Prior to establishing the GCCF, emergency compensation was paid by BP from an initial facility. Due to the effectiveness and lower cost of bioremediation, two methods. The report places some of the blame for the accident on BP but also on Halliburton and Transocean. [353], In September 2014, Halliburton agreed to settle a large percentage of legal claims against it by paying $1.1billion into a trust by way of three installments over two years. It also included economic damage claims submitted by the five Gulf states and their local governments. [68], In 2013, more than 4,600,000lb (2,100t) of "oiled material" was removed from the Louisiana coast. On October 5, 2015, we proposed a comprehensive, integrated, ecosystem restoration plan to address impacts from the spill to the Gulf of Mexico. [370][371], This article is about the oil spill itself. BP said administration of the 2012 settlement was marred by the fact that people without actual damages could file a claim. [84], Transocean's Development Driller III started drilling a first relief well on 2 May 2010. The oil well was capped three months later, after 24/7 news coverage.
