Oil overload

An investigation by state inspectors claims that a recent oil spill in the San Francisco Bay in October was caused by a fuel tank overflowing.

The California Office of Spill Prevention investigation found that crew members of the Dubai Star didn’t notice the tank was overflowing at a refueling station until oil had already leaked into the bay, according to The Associated Press.

Originally, the spill was blamed on a faulty hose. Inspectors are still trying to figure out what caused the tank to overflow, as crew members do not appear to be at fault.

Authorities say the oil stretched along six miles of Alameda coastline and killed nearly 40 birds.
