Start of phase two of trial. Sept. 30, 2013.

Expert testimony on how much oil flowed into the Gulf of Mexico during the 2010 oil disaster is expected to wrap up today in a New Orleans federal courtroom. This testimony is part of the Quantification Segment of the second phase of the BP trial, which began on September 30 and is ending a full week earlier than expected. Phase two is focused on efforts to stop the flow of oil from the well (Source Control Segment) and how much oil spewed into the Gulf of Mexico during the 87-day disaster (Quantification Segment). Phase one of trial, which lasted two months and ended in April, covered the events that caused the Deepwater Horizon rig explosion. Despite the nearly concurrent federal government shutdown, trial continued relatively unfazed over the past three weeks.

Phase two kicked off with the Source Control Segment, where presiding Judge Carl Barbier heard testimony on the multiple engineering feats BP attempted to seal the uncontrolled Macondo well. The Quantification Segment pitted the U.S. Department of Justice against BP, each side offering conflicting expert testimony on the amount of oil that gushed from the well. The Quantification Segment is focused on a simple question with a not-so-simple answer: How much oil did BP spill into the Gulf of Mexico? Under the Clean Water Act, BP is subject to per-barrel fines based on how much oil was released into the Gulf. The government believes BP is liable for 4.2 million barrels, while BP contends they are responsible for no more than 2.45 million barrels. Each side is offering highly complex and technical scientific and engineering evidence related to how they estimated the total amount offered in court, and the judge will consider these testimonies when he determines how much BP will pay.

BP has maintained that the government exaggerated the amount of oil spilled during the disaster. The company argues that flow rates offered by the government were generated “over a single weekend” at the beginning of the spill. BP contends that the flow rate from the well was variable over time, and that it actually decreased as the spill progressed. Attorneys for the government attacked BP’s witnesses’ findings and even suggested potential bias, citing a $100 million donation made by BP to the Imperial College London which employs two of BP’s trial witnesses.

While it is plausible that Judge Barbier will come down somewhere in the middle of the 2.45 to 4.2 million barrel range, the total amount of Clean Water Act fines could quadruple if BP is found grossly negligent. A ruling on negligence, which has not been issued, will likely be based on evidence from both phase one and phase two of trial. Judge Barbier has noted that he will schedule a third penalty phase to help him assess fines in the case, presumably sometime next year. Eighty percent of the penalty money assessed in this case under the Clean Water Act will be distributed to the Gulf Coast states for restoration through the RESTORE Act, the federal law passed last year.
