Fifteen years after the Deepwater Horizon blowout, the BP oil spill settlement has cost the company more than $65 billion across criminal fines, civil penalties, private claims, and Gulf Coast restoration commitments. Most of the money has been paid or committed, restoration payments will continue flowing through 2031, and the economic and property claims programs are closed to new filings. What remains genuinely unresolved is the health litigation: roughly 4,800 to 5,000 lawsuits by cleanup workers, nearly all dismissed, with appeals now pending that could decide whether any realistic path to compensation still exists.
The $20.8 Billion Civil Settlement
The centerpiece of the resolution is the civil settlement announced on October 5, 2015 and approved by a federal court on April 4, 2016. At $20.8 billion, it is the largest environmental settlement in U.S. history, and the payments are spread over 15 years.1U.S. Department of the Interior.

The money is divided into four main buckets:
- A $5.5 billion Clean Water Act civil penalty, the largest under that statute. Under the RESTORE Act, 80 percent ($4.4 billion) goes to the Gulf Coast Restoration Trust Fund and 20 percent ($1.1 billion) to the federal Oil Spill Liability Trust Fund.
- Up to $8.8 billion in natural resource damages, including $1 billion previously committed under early restoration agreements and up to $700 million reserved for adaptive management and unknown future conditions.
- $5.9 billion in separate agreements resolving state economic damage claims from Louisiana, Mississippi, Alabama, Florida, and Texas.
- $350 million to reimburse damage-assessment costs and $250 million for response and removal costs.2Ocean Conservancy. BP Settlement Fact Sheet

The $4 Billion Criminal Resolution
The civil settlement sits on top of a separate criminal case. BP Exploration and Production Inc. pleaded guilty on January 29, 2013 to a 14-count criminal information, including 11 felony manslaughter counts for the deaths of the rig workers, one felony count of obstruction of Congress, and violations of the Clean Water Act and Migratory Bird Treaty Act.5U.S. Department of Justice.

About $2.4 billion of that criminal fine was directed to the National Fish and Wildlife Foundation’s Gulf Environmental Benefit Fund for coastal and marine habitat restoration, with half of that amount designated specifically for Louisiana.4NOAA.

Transocean and Halliburton Paid Separately
BP did not pay alone. Transocean, the rig’s owner, paid a total of $1.4 billion: a $400 million criminal penalty after pleading guilty to a Clean Water Act misdemeanor, plus a $1 billion civil penalty under a separate consent decree, along with five years of probation.7U.S. Department of Justice.

Private Economic Claims Are Closed
If you are searching now with the idea of filing a private economic claim, that door has shut. BP’s initial Gulf Coast Claims Facility paid more than $6 billion to roughly 222,000 claimants over about 18 months.10Illinois Law Review. Paying the Price for Environmental Disaster In March 2012 the court transitioned private claims to a Court-Supervised Settlement Program under claims administrator Patrick Juneau, covering six categories of damages including economic loss, property damage, and seafood compensation (capped at $2.3 billion).11U.S. District Court, Eastern District of Louisiana.

Why Health Claims Have Mostly Failed
The one part of the litigation still meaningfully open is the health side, and the results so far have been grim for plaintiffs. A 2012 medical benefits settlement was supposed to compensate cleanup workers and coastal residents who developed illnesses from oil or chemical exposure. In practice, BP paid roughly $67 million to about 23,000 approved claimants. Nearly 80 percent received $1,300 or less. Only 40 people received the maximum award of $60,700.13Anchorage Daily News. Once Praised, the Settlement to Help Sickened BP Oil Spill Workers Leaves Most With Nearly Nothing
A term change in the settlement is a large part of the story. The original agreement used the word “manifests” for when a later-developing illness would qualify for a Back-End Litigation Option, allowing claimants to sue individually. The final language changed that word to “diagnosed,” which effectively barred thousands of workers whose symptoms emerged gradually and pushed them into federal court. Judge Carl Barbier, who oversees the multidistrict litigation, said at a 2014 hearing that it was “rather strange” to approve a settlement that “really doesn’t settle thousands of claims and requires them to file another lawsuit.”13Anchorage Daily News. Once Praised, the Settlement to Help Sickened BP Oil Spill Workers Leaves Most With Nearly Nothing
Roughly 4,800 to 5,000 federal lawsuits followed. All but a handful have been dismissed. Attorneys involved in the litigation know of only one successful individual settlement: former boat captain John Maas, who received $110,000 in 2022.14KFF Health News. BP Deepwater Horizon Oil Spill Cleanup Workers Health Problems
The obstacle is causation. Federal judges have required plaintiffs to prove that exposure to specific chemicals at specific levels caused their particular illness. Dale Sandler, the lead government epidemiologist on spill-related health research at the National Institutes of Health, has said that standard is “likely impossible to meet” because transient oil components like benzene had dissipated from workers’ blood by the time formal studies began.14KFF Health News.

The Fifth Circuit heard arguments in December 2024 on whether district courts have applied an excessively demanding causation standard. During oral argument, one circuit judge expressed doubt that cleanup workers’ claims could survive the current evidentiary bar, and another said the issue is “very ripe for the Supreme Court to resolve.”16Law360. 5th Circ. Judge Doubts Deepwater Horizon Claims Can Survive Those pending appeals will determine whether the roughly $67 million medical settlement remains effectively the last word for the tens of thousands of workers who got sick.
Where Restoration Money Is Going Now
The bulk of the settlement money that is still moving is restoration funding, and it flows through three main channels: the Natural Resource Damage Assessment (NRDA) Trustee Council, the RESTORE Act Trust Fund, and the National Fish and Wildlife Foundation’s Gulf Environmental Benefit Fund.
Natural Resource Damages
The NRDA Trustee Council, which includes federal and state agencies plus the EPA, oversees the $8.8 billion in natural resource damage funds. As of April 2025 the council had approved more than 300 restoration projects totaling $5.38 billion, with 20 to 60 percent of funding allocated across categories including habitat conservation, water quality, living coastal and marine resources, and recreational use.17NOAA Gulf Spill Restoration. 15 Years After Deepwater Horizon: Statement From the Natural Resource Damage Assessment Trustee Council Approved projects include the Lake Borgne Marsh Creation project in Louisiana, restoring over 2,700 acres of marsh using 13 million cubic yards of dredged material, and the Pensacola Bay Living Shoreline in Florida, completed in 2021.
RESTORE Act Funding
The RESTORE Act, signed in 2012, directs 80 percent of BP’s Clean Water Act penalties into the Gulf Coast Restoration Trust Fund. The fund is split five ways: 35 percent for a Direct Component administered by the Treasury for state-proposed projects; 30 percent for council-selected regional restoration; 30 percent for a Spill Impact Component based on state expenditure plans; and 5 percent split between NOAA science programs and Centers of Excellence research grants.18U.S. Department of the Treasury. RESTORE Act Under the Spill Impact Component, Louisiana receives the largest allocation at roughly $555 million, followed by Alabama ($327 million), Mississippi ($306 million), Florida ($294 million), and Texas ($122 million).19Gulf Coast Ecosystem Restoration Council.

In June 2026, the RESTORE Council unanimously approved its latest Funded Priorities List, committing $403.6 million in new funding for 19 ecosystem restoration projects.20Gulf Coast Ecosystem Restoration Council. Restore the Gulf Alabama alone was approved for $87 million in projects, including a $38 million dune restoration effort on Dauphin Island and a $24 million wetland creation initiative using dredged material from the Port of Mobile.21Governor of Alabama.

NFWF Gulf Environmental Benefit Fund
The National Fish and Wildlife Foundation received $2.544 billion from BP’s criminal fine. As of its most recent reporting, the fund has supported 209 projects with investments exceeding $1.7 billion, leveraging an additional $1 billion in partner contributions, and is designed to protect or restore nearly 225,000 acres of wetlands and coastal habitat, including more than 1,100 acres of oyster reef.22National Fish and Wildlife Foundation. Gulf Environmental Benefit Fund Texas has already exhausted its Deepwater Horizon allocation, spending $441 million between 2013 and 2020 to cover over 112,000 acres of habitat.23Environment America.

Louisiana Canceled Its Largest Restoration Project
The most significant recent development in settlement spending is Louisiana’s cancellation of the Mid-Barataria Sediment Diversion, which had been billed as the largest ecosystem restoration project in U.S. history. It was designed to reconnect the Mississippi River to disappearing wetlands in Plaquemines Parish and rebuild up to 40 square miles of land over 50 years. Construction broke ground in August 2023 after more than 15 years of research and engineering. Louisiana had already spent roughly $560 million on design and permitting, and NFWF had approved $660 million for construction in early 2023.24National Audubon Society. Louisiana Pulls Plug on Nation’s Largest Ecosystem Restoration Project
Shortly after Governor Jeff Landry took office, his administration paused the project in April 2025 for 90 days, citing cost concerns and potential harm to local oyster and shrimp fisheries.25Verite News. 15 Years After the BP Deepwater Horizon Oil Spill The U.S. Army Corps of Engineers then suspended the federal permit. On July 17, 2025, the Louisiana Coastal Protection and Restoration Authority and the Louisiana Trustee Implementation Group formally terminated the project, with CPRA declaring it “no longer viable.” The authorized budget was slashed from $2.26 billion to $618.5 million, reflecting only funds already spent, and unused settlement money is to be redirected to other Deepwater Horizon restoration projects in Louisiana.26NOAA Gulf Spill Restoration. Louisiana Moves to Terminate Mid-Barataria Sediment Diversion Project The National Audubon Society and the Restore the Mississippi River Delta coalition called the decision a departure from science-based coastal planning and a threat to the state’s long-term Coastal Master Plan.

What’s Still Open
BP’s 15-year payment schedule for the civil settlement continues. Clean Water Act penalty payments run through 2031, with natural resource damage payments extending alongside them. Texas expects its total settlement payouts of more than $1 billion to conclude in 2033, with about $52 million in NRDA funds still unspent and $550 million in RESTORE Act funding continuing to flow.23Environment America.

The economic and property damage claims programs are closed, and the medical benefits filing deadline has passed. What’s left is a small number of pending health cases, including the appeals in the Fifth Circuit that could reshape the causation standard for toxic exposure claims. If those appeals go the plaintiffs’ way, thousands of dismissed and stalled cleanup-worker cases could get a second look. If they don’t, the $67 million medical settlement is where the story ends for most of the people who got sick.
