The U.S. Coast Guard is considering a policy change to allow the transport of wastewater from hydraulic fracturing, or fracking, on inland waterways.
Oil and gas companies currently transport most of their wastewater by truck from the shale fields in Ohio and Pennsylvania to states with lighter regulations on storage, like Texas and Louisiana.
Now companies want to take the river route to save on fuel and personnel costs. But chemicals and other minerals in the wastewater could prove too risky to move by barge.
The U. S. Army Corps of Engineers plans to reduce operating hours at the Barkley Navigation Lock to save money. The Corps announced Monday it will go from a 24 hour to a 20 hour a day operation, starting Jan. 7, 2013.
