AKRON, Ohio (AP) - Booming energy production in shale formations has made a northeast Ohio county the top location in the state for underground injection of drilling wastes.
Portage County, home of Kent State University, had enough drilling waste injected deep into the ground in 2012 to fill a train of tanker cars that would stretch nearly 37 miles. The rankings were reported Sunday by the Akron Beacon Journal.
According to the Ohio Department of Natural Resources, Washington County ranked second for injections. Nearby Noble County ranked fifth.
Out-of-state shipments account for 57.6 percent of the waste going into Ohio's injection wells, up from 54 percent the previous year. In 2012, 6 million barrels came from Ohio drillers and 8.2 million barrels from other states, mostly Pennsylvania and West Virginia.
