More than 700 spills were reported at oil and gas operations in Colorado last year, according to the latest data compiled from a state database by the Center for Western Priorities.

The spills that occurred on an average of two per day released more than a million gallons of oil and other chemicals, mainly in Weld County and in the Piceance Basin of Western Colorado.

The spills were most often caused by equipment failure or human error, the data showed. They occurred when tanker trucks tipped over, containment ponds leaked or overflowed or pipes were corroded. Some of the spills had happened years earlier but were not discovered until 2014.
