To assist with the efforts the captains had to register their ships with the Vessels of Opportunity; however, an issue arose when more boats registered than actually participated in the clean-up efforts only a third of the registered boats. A lock (LockA locked padlock) or https:// means youve safely connected to the .gov website. So began an 87-day oil spill that spewed 3.19 million barrels, or nearly 134 million gallons, into the Gulf of Mexico. [210], In the first birthing season for dolphins after the spill, dead baby dolphins washed up along Mississippi and Alabama shorelines at about 10times the normal number. [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. BP will pay $4.5billion in fines and other payments, the largest of its kind in US history. NIOSH did note that many of the personnel involved were not donning personal protective equipment (gloves and impermeable coveralls) as they had been instructed to and emphasized that this was important protection against transdermal absorption of chemicals from the oil. With a decrease in microbial diversity and members in these communities, many nutrients cycles are disrupted; this further affects microbes and organisms in general. Many low-wage workers in the fishing and service industries, for example, have been seeking compensation for lost wages and jobs for three years. Air concentrations of volatile organic compounds and PAHs never exceeded permissible exposure levels. 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. A Berkeley Lab bioremediation expert says extreme caution must be used in cleaning up the fragile Gulf Coast ecosystem in the aftermath of the Deepwater Horizon oil spill. The oil dispersant Corexit, previously only used as a surface application, was released underwater in unprecedented amounts, with the intent of making it more easily biodegraded by naturally occurring microbes. [81][324] This fund was set aside for natural resource damages, state and local response costs, and individual compensation, but could not be used for fines or penalties. Cleaning efforts were implemented soon after that using surfactants to disperse the oil to create more surface area for decomposition by microorganisms and other forms of bioremediation . 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. NWF senior scientist Doug Inkley notes that the marine death rates are unprecedented and occurring high in the food chain, strongly suggesting there is "something amiss with the Gulf ecosystem". NOTE: If you need captions, please click the CC button on the player to turn them on.Unprecedented in both scope and nature, the April 20, 2010 Deepwater Hor. 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. In the case of the Deepwater Horizon oil spill, clean-up workers treated the oil with over 1.4 million gallons of various chemical dispersants. The US government report issued in September 2011 stated that BP is ultimately responsible for the spill, and that Halliburton and Transocean share some of the blame. In the Deepwater Horizon disaster (2010, Gulf of Mexico), where an oil rig exploded that produced the worst spill in history, bioremediation techniques were applied when it was verified that the spilled oil had bacterial activity. [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. On September 17 the bottom kill maneuver was successfully executed through the first relief well. Deepwater Horizon Oil Spill and Physical Health among Adult Women in Southern Louisiana: The Women and Their Childrens Health (WaTCH) Study. This adds to the already soaring greenhouse gas concentration. In summer 2010, approximately 47,000people and 7,000vessels were involved in the project. These traditional techniques are limited in effectiveness and are expensive due to the large area affected by the BP oil spill. [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. Benthic and highly productive habitats such as marshes and coastal wetlands in the affected areas were contaminated with crude oil and other petroleum by products; they are harmful to many of the organisms that thrive there [2]. The paper is titled "Oil biodegradation and bioremediation: A tale of the two worst spills in U. S. history." . Many died from ingesting oil or because it interfered with their ability to regulate their body temperatures. Restoring the Gulf of Mexico After the Deepwater Horizon Oil Spill, 2010 National Coastal Condition Assessment Results and Report, National Enforcement and Compliance Initiatives, Enforcement and Compliance Annual Results for FY 2022, February 17, 2012: $90 million civil settlement with, January 3, 2013: $1 billion civil settlement with, RestoreTheGulf: official federal government site for spill. [100] Repeated scientific analyses confirmed that the sheen was a chemical match for oil from the Macondo well. Crude oil is a heterogeneous hydrophobic compound that contains four classes of molecules: saturates, aromatics, asphaltenes, and resins [10] . The well is situated in the Macondo Prospect in Mississippi Canyon Block 253 (MC253) of the Gulf of Mexico, in the United States' exclusive economic zone. Testing over the past year (2019) reported by GulfSource.org, for the pollutants tested have not produced results.[186]. [23][24][25] As of 2018[update], cleanup costs, charges and penalties had cost the company more than $65billion. 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. These projects allowed restoration of the Gulf to begin immediately. Problems include the fact that microbes being introduced may require different conditions in order to grow, indigenous organisms out compete the new comers, and if growth is observed, it may not reach a high enough concentration to have an observable effect on the degradation of oil. In July 2010, it was reported that the spill was "already having a 'devastating' effect on marine life in the Gulf". The Deepwater Horizon accident has brought oil contamination of deep-sea environments to worldwide attention. [59][162] By mid-September, other research claimed that microbes mainly digested natural gas rather than oil. [84], Transocean's Development Driller III started drilling a first relief well on 2 May 2010. "[295] Later, he drew an outpouring of criticism when he said that the spill was a disruption to Gulf Coast residents and himself adding, "You know, I'd like my life back. Oil is a biological. In their statement the DOJ said that some of BP's arguments were "plainly misleading" and that the court should ignore BP's [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. Blake D A, John V and Lvov Y M 2018 Bacterial proliferation on clay nanotube Pickering emulsions for oil spill bioremediation Colloids Surfaces B Biointerfaces. Deepwater Horizon Oil Spill: Coastal Wetland and Wildlife Impacts and Response - M. Lynne Corn - Google Books Search Images Maps Play YouTube News Gmail Drive More Calendar Translate Mobile Books. In total 2,063 various skimmers were used. When oil from the Deepwater Horizon spill first began washing ashore on Pensacola Municipal Beach in June 2010, populations of sensitive microorganisms, including those that capture sunlight or fix nitrogen from the air, began to decline. Calling the vicinity of the spill "one of the most productive ocean ecosystems in the world", the study found that even at very low concentrations "PAH cardiotoxicity was potentially a common form of injury among a broad range of species in the vicinity of the oil. Boat captains were given the opportunity to offer the use of their boats to help clean and prevent the oil from further spreading. Claims by several research groups that subsurface plumes of dispersed hydrocarbons had been detected in May were initially dismissed by BP and the National Oceanic and Atmospheric Administration (NOAA). Fortunately, unlike higher organisms that are adversely impacted by oil spills, microorganisms are able to . Two weeks after the wellhead was capped on 15 July 2010, the surface oil appeared to have dissipated, while an unknown amount of subsurface oil remained. One of the largest oil spills, known as the Deepwater Horizon oil spill, occurred in the Spring of 2010 near the coast of Louisiana (USA) due to an explosion during oil drilling activities. [6][46] BP challenged the higher figure, saying that the government overestimated the volume. [147] One plume was 22mi (35km) long, more than 1mi (1,600m) wide and 650ft (200m) deep. A large scale of bioremediation was deployed during the BP oil spill crisis due to its effectiveness and lower cost [8]. [36][40] The Deepwater Horizon sank on the morning of 22 April 2010. For the Deep Horizon oil spill, cleanup workers used 1,400,000USgal (5,300,000l; 1,200,000impgal) of various chemical dispersants to further breakdown the oil. . [336][337] On 13 August, BP asked US District Judge Carl Barbier to approve the settlement, saying its actions "did not constitute gross negligence or willful misconduct". [74] Pumping heavy drilling fluids into the blowout preventer to restrict the flow of oil before sealing it permanently with cement ("top kill") also failed. The U.S. State Department listed 70 assistance offers from 23 countries, all being initially declined, but later, 8 had been accepted. Responding to Oil Spills in the U.S. Arctic Marine Environment reviews the current state of the science regarding oil spill response and environmental 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,[6][7][8][9] 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 Ixtoc I oil spill, also in the Gulf of Mexico. [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. This is the preferred method when members of the indigenous microbial community are capable of degrading oil [10]. On December 15, 2010, the United States filed a complaint in District Court against BP Exploration & Production and several other defendants alleged to be responsible for the spill. Below is a summary of areas in which more research needs to be done. 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. [63][64][65], That means that over 10010^6USgal (380Ml) (2.4million barrels) remained in the Gulf. What are some alternative methods to increase surface area of hydrophobic molecules on water surfaces? [203] Damage to the ocean floor especially endangered the Louisiana pancake batfish whose range is entirely contained within the spill-affected area. [187] The U.S. It is possible to add fertilizers, such as iron, nitrogen and phosphorus, to stimulate the growth of such bacteria, an approach used to speed up microbial activity in the sediment along the Alaska. It uses microorganisms or biological agents to treat oil spills, and soils contaminated 4. [322] The report concluded that the primary cause of failure was that the blind shear rams failed to fully close and seal due to a portion of drill pipe buckling between the shearing blocks. [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. BioWorld Hydrocarbon Treatment was added to weathered oil from the Gulf. 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]. Natural Resource Damage Assessment (NRDA). The explosion, which killed 11 men, caused the rig to sink and started a catastrophic oil leak from the well. The draft plan allocated up to $8.8 billion for restoration from a proposed settlement with BP. A limitation of their methodology was that some VOCs may have already evaporated from the oil before they began their investigation. [223] In 2013, former NASA physicist Bonny Schumaker noted a "dearth of marine life" in a radius 30 to 50mi (48 to 80km) around the well, after flying over the area numerous times since May 2010. 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. BP responded that the concentrations of oil in the study were a level rarely seen in the Gulf, but The New York Times reported that the BP statement was contradicted by the study.[19]. Researchers concluded that deep plumes of dissolved oil and gas would likely remain confined to the northern Gulf of Mexico and that the peak impact on dissolved oxygen would be delayed and long lasting. A 100% reduction in alkanes and a 85.1% reduction in PAHs were demonstrated over 28 days. [293] In June 2018, the executive order establishing the National Ocean Council was revoked by then-U.S. president Donald Trump in an effort to roll back bureaucracy and benefit "ocean industries [that] employ millions of Americans". The report places some of the blame for the accident on BP but also on Halliburton and Transocean. [3] For marshes, techniques such as vacuum and pumping, low-pressure flush, vegetation cutting, and bioremediation were used. Now, a team of American scientists led by Terry Hazen have shown that just a. Is there a way to inhibit full degradation of petroleum while producing non toxic organic compounds? [247] An independent investigation for Newsweek showed that BP did not hand out the legally required safety manual for use with Corexit, and were not provided with safety training or protective gear. were used to cleanup after the Deepwater Horizon oil spill. The oil well was capped three months later, after 24/7 news coverage. [23][59] Oil sector analysts at London-based investment bank Canaccord Genuity noted that a settlement along the lines disclosed would only be a partial resolution of the many claims against BP. [23] Transocean pled guilty to a misdemeanor charge as part of its $1.4billion fine. 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] . Only about 800,000 barrels had been captured. It set five goals: In 2011, one year after the Deepwater Horizon oil spill, BP agreed to provide up to $1 billion toward early restoration projects in the Gulf of Mexico. [56] In October, weathered oil reached Texas. Clean Water Act, RESTORE Act, Oil Pollution Act and criminal statutes lead to $20.8B settlement, largest in U.S. history, Unprecedented funding to support Gulf-wide restoration and research, Major restoration programs funded for next 30 years, NOAA, Department of the Interior and Gulf states developing a 15-year plan, Explosion triggered economic, environmental devastation, and a legal battle, The RESTORE Act results in funding buckets, Settlement to fund a coordinated restoration effort, National Oceanic and Atmospheric Administration, Number of adult oysters lost to the marketplace because of the, What resulted from this one incident was an economic, political, scientific and legal nightmare. Rob Williams, et al. Diaz also believes neurological disorders should be expected. [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]. Although BP attempted to activate the rigs blowout preventer (BOP), a fail-safe mechanism designed to close the channel through which oil was drawn, the device malfunctioned. [16] In April 2013, it was reported that dolphins and other marine life continued to die in record numbers with infant dolphins dying at six times the normal rate. [342][344], On 14 November 2012, BP and the US Department of Justice reached a settlement. [319] Still another was for not plugging the pipe with cement. [263][264][265] The U.S. Travel Association estimated that the economic impact of the oil spill on tourism across the Gulf Coast over a three-year period could exceed approximately $23billion, in a region that supports over 400,000travel industry jobs generating $34billion in revenue annually.
