STOCKTON – A small oil spill triggered a big response Tuesday at the Port of Stockton.

Champion, a Norwegian-registered oceangoing ship carrying liquid fertilizer, had been slowly leaking hydraulic fluid from its rudder since arriving in port Monday, said Jeff Wingfield, an environmental manager at the port.

But it doesn’t take much fuel – about a gallon, in this case – to create a noticeable sheen on the water, he said. The spill was detected and reported to the California Emergency Management Agency about 1 p.m. Tuesday.
