oil spill, the largest marine oil spill in the history of the petroleum industry. In 2019, Taylor Energy went to court to stop the government's efforts to fix the leak, filing four lawsuits against the Interior Department, U.S. Coast Guard, and Couvillion Group. The Couvillion Group, a marine construction company based in Belle Chase, Louisiana, was hired by the government to recover and contain the spill in 2019; in April 2019, the company built an underwater containment system. In its first year of operation, the system retrieved around 400,000 gallons of oil; the Coast Guard considers a release of 100,000 gallons of oil in coastal waters a "spill of national significance." The company had collected over a million gallons of oil as of July 2022. The lawsuit against Couvillion Group by Taylor Energy for “trespassing” as they worked to contain the spill was dismissed by U.S. District Court Judge Greg G. Guidry on August 21, 2020.
