The tanker Athos I, carrying crude oil from Venezuela, was preparing to dock at a refinery in New Jersey when it ripped its hull on a submerged anchor. This caused its cargo of oil to begin gushing into the Delaware River. (NOAA)

Athos I Oil Spill on the Delaware River

On November 26, 2004, the single-hulled tanker Athos I unknowingly struck a large anchor submerged in the Delaware River while preparing to dock at a refinery just outside Philadelphia, Pennsylvania. The impact punctured the tanker's hull, and it began leaking more than 263,000 gallons of heavy oil into the tidal waters of this busy East Coast shipping route. NOAA's Office of Response and Restoration, along with other federal, state, and local agencies, provided scientific support during the oil spill cleanup and response. They also assessed the environmental and recreational impacts of the spill and, in 2010, received $27.5 million for restoration. This money is funding 10 restoration projects to benefit coastal communities and natural resources which the oil spill affected.
