The massive oil spill still isn't fully cleaned up three years and three months after it happened. The company responsible hasn't even set a date for completion. Some say that one of the largest onshore oil spills recorded in the U.S. serves as a cautionary example, especially given a recent pipeline break about 150 miles south and ongoing debates over the four-state Dakota Access pipeline.
