A spokesman for the company DCP Midstream said the fire burned for about 30 minutes before a gas valve was shut-off.

According to Piedmont Fire Chief Andy Logan, the explosion was the result of a rupture in a 12-inch high-pressure underground line. The blast left a crater-sized hole roughly 30 feet long and 20 feet wide.
