Fallout from the Dec. 31 4.0-magnitude earthquake near a Youngstown injection well for drilling wastes continues to roll in.
Youngstown Mayor Charles Sammarone, a Democrat, wants City Council to approve legislation backing a moratorium on injection wells.
Only the state could impose such a moratorium, but the mayor is mustering support after the 11th quake since March hit the Youngstown area near the injection well operated by D&L Energy Inc.
The company and the state of Ohio had agreed on Dec. 30 to shut down the injection well in Youngstown Township west of downtown Youngstown because of the continuing small quakes.
State Sen. Joe Schiavoni, D-Canfield, wants public hearings in the Youngstown area on the quakes.
State Sen. Bob Hagan, D-Youngstown, was one of the first to call for a moratorium.
The Ohio Department of Natural Resources has ordered four not-yet-operating injection wells within a 5-mile radius of the problem well to remain closed. It is investigating the quakes.
The grass-roots group, Network for Oil & Gas Accountability and Protection, issued a call today to halt hydraulic fracturing or fracking in Ohio, in light of the Youngstown quakes.
"Today it's earthquakes. What other unknowns are out there? We're dealing with some serious geologic issues and even the experts don't fully understand," said NEOGAP president Vanessa Pesec. For more details, check out the link.
Experts have predicted that the Youngstown quakes could continue for weeks and months.
Ohio has 177 active injection wells that take salty drilling waste from Ohio and Pennsylvania.
Gov. John Kasich said the problems appear only at the Youngstown well and said that Ohio will continue to use the other disposal wells without interrupting shale-gas development.
The Youngstown well typically took in 3,000 to 5,000 42-gallon barrels per day. In the first nine months of 2011, it took in 14.8 million gallons, according to state records.
The wastes were pumped to depth of 9,200 feet under pressure.
Industry groups like the Ohio Oil and Gas Association and the Ohio Petroleum Council defended the injection wells, said Ohio needs them and called the problems unusual and linked only to the one well.
