One North Dakota cow is being blamed by officials for spilling around 20 barrels of natural gas condensate in late-May.
According to the Associated Press, North Dakota State Environmental officials believe a cow in western North Dakota rubbed against a tank valve to open and created the leak.
State Environmental Health Chief Dave Glatt believes the cow was either curious or had an itch.
“They just get rubbing along those valves and they open up,” Glatt said. “Sometimes they need to scratch their backs and they open those valves.”
Cleanup is underway, and officials placed absorbent booms in a nearby creek as a precaution.
Officials are now left reminding oil companies to keep their production and storage facilities bovine-proof.
Believe it or not, a similar spill was also blamed on cows several years ago.
