At 4:27 p.m. the Miss Kelly sank with approximately 600 gallons of diesel on board. Three fuel tanks remain floating on the surface. A light sheen is also visible on the surface where the vessel sank. Coast Guard pollution investigators contacted the National Oceanic and Atmospheric Administration for an air plume model to assess potential air pollution headed to shore.
Coast Guard Sector Columbia River located in Warrenton, Ore., will continue to monitor the situation.
