Offshore oil drilling is a common practice to remove oil from the ocean, and has led to a series of oil spills. On Oct. 1, the U.S. Coast Guard received a report of a petroleum smell off the coast of Huntington Beach, according to The Guardian. An underwater oil pipeline had cracked and was leaking oil into the ocean. The pipeline is owned by Amplify Energy based in Houston, Texas, who will likely be held as a responsible party. The exact timeline of the oil spill remains unclear, leading to an investigation into its origins by the U.S. Coast Guard.
