A well pad explosion and fire at XTO Energy's Powhatan Point, OH site prompted a mandatory one-mile evacuation radius for residents living near the Powhatan Point, OH, site. First responders from across the country rushed to the area to help activate emergency response procedures. A U.S. EPA report estimates that the damaged well leaked methane at a rate of 80 tons an hour for nearly 20 days, one of the largest methane leaks in American history.
