State Natural Resources Director Reaches Agreement to Halt Operation of Youngstown Area Injection Well

Injection Well Locations in Ohio

COLUMBUS, OH—Ohio Department of Natural Resources Director James Zehringer today announced a halt to operations at a Youngstown Township fluid injection well. The area surrounding the well has experienced a series of low-level seismic events over the past eight months. While conclusive evidence cannot link the seismic activity to the well, Zehringer has adopted an approach requiring prudence and caution regarding the site.

“Our top priority is the health and safety of the public and the protection of Ohio’s natural resources,” said Zehringer. “We are going to make sure this process is done right and won’t hesitate to stop operation of disposal sites if we have concerns. And while our research doesn’t point to a clear and direct correlation to drilling at this site and seismic activity, we will never gamble when safety is a factor.”

The class two injection well is owned and permitted by Northstar Disposal Services, LLC of Youngstown.

Following a series of low-level seismic events this year in the area surrounding the Youngstown Township injection well, ODNR invited Columbia University’s Lamont-Doherty Earth Observatory to position four seismometers in the area to capture more detailed information about seismic activity.

“Information freshly obtained from the Columbia University scientists, and further analyzed by ODNR geological experts, indicates that an earthquake occurred on December 24 approximately two miles below and within a mile of the injection site,” said Zehringer. “As a precautionary measure we’ve reached agreement with the well’s owner to halt injections until we are able to further assess and determine any potential links with recent seismic events.”

So far this year ODNR’s seismic monitoring network has documented 10 seismic events occurring in 2011 within two miles of this injection well. Each of these events registered at 2.7 magnitude or lower. Generally, only earthquakes that register above 4 magnitude are known to cause surface damage. As a relative measure, a 4 magnitude event would release approximately 40 times the energy of a 2.7 magnitude event.

There are 177 class 2 deep well injection sites operating in Ohio.
