Ventura City Fire crews were able to contain a 500-gallon diesel fuel spill in the Ventura Harbor Village.
Officials said a broken fuel tank started leaking into the ocean just after 1:15 p.m. Monday.
Hazardous materials teams from various local agencies responded to a squid boat docked in the harbor.
Witnesses said the 62' squid boat leaking fuel had collided with another fishing boat at the dock.
The impact pierced the stern area and ruptured the diesel fuel tank on the squid boat. The boat's captain estimated 500 gallons of diesel was spilled into the harbor near Harbor Village.
Crews off-loaded fuel from that tank and patched the hole. Firefighters and Harbor Patrol crews placed containment booms around the docks to absorb the fuel.
Hazardous Materials Teams also used sophisticated equipment to monitor the atmosphere. They conducted ignition assessments to make sure the spill wouldn't cause a fire. Coast Guard and Harbor Patrol officers will continue to monitor the clean up effort.
