"The handling of an oil spill in North Dakota is raising questions, after a state agency waited to tell the public it had taken place. A wheat farmer was the first to recognize the spill had happened; it became public knowledge nearly two weeks later."
"Here's how the AP describes the spill's discovery:
'Farmer Steve Jensen says he smelled the crude for days before the tires on his combines were coated in it. At the apparent break in the Tesoro Corp.'s underground pipeline, the oil was 'spewing and bubbling 6 inches high,' he said in a telephone interview Thursday.'"
