It's hard to forget the videos of oil spewing forth from the hole at the bottom of the Gulf of Mexico. The Deepwater Horizon accident took 87 days to cap off. But it will take thousands and thousands of days to totally clean up. The job of overseeing what might be a 15-year effort belongs to Christopher Doley, chief of habitat restoration at the National Oceanic and Atmospheric Administration. He's also a finalist for this year's Service to America Medals. He spoke to Federal Drive with Tom Temin about the cleanup effort.
