People operating recreational craft, such as Jet Skis and boats, sometimes spill oil into the ocean.
“It’s usually operational error, human error or unpreparedness, [or] lack of education. A lot of time mostly it’s just negligence,” said Aaron Barnett, a boating program specialist at Washington Sea Grant, a state-federal partnership aimed at marine research and outreach across Washington State.
“It’s just not on [boaters’] radar scope. They’re there to have fun, it’s leisure, it’s recreation. … That means that certain things don’t get dealt with, like proper engine maintenance.”
Barnett added that boat owners will top off their fuel tanks as they would a car, and on a hot day the fuel expands and escapes through a vent.
Just like land-based pollution, though, oil spills by recreational boats are “hard to track, because about 80 percent of oil spills go unreported, so there’s really no way to know” on what scale this is happening, Barnett said.
Overall, he said, the Environmental Protection Agency “looks at the small-oil-spill problem as sort of like death by a thousand cuts.”
