SEATTLE - John Swain, a technician for the National Response Corporation Environmental Services, is onboard a MARCO skimmer conducting clean up of the oil spill in Tacoma Wash., at Pier 25 December 11, 2007. The MARCO recovery system utilizes a powerful induction pump behind a continuous, moving, oil-absorbing belt. Recovered oil is then scraped and squeezed from the belt into a sump, and debris is collected in a separate container. (Official Coast Guard photo by Petty Officer David Marin)
