A northeast Ohio well used to dispose of wastewater from oil and gas drilling almost certainly caused a series of 11 minor earthquakes in the Youngstown area since last spring, a seismologist investigating the quakes said Monday.
Research is continuing on seismic activity near the now-shuttered injection well at Youngstown, Ohio, but it might take a year for the wastewater-related rumblings in the earth to dissipate, said John Armbruster of Columbia University's Lamont-Doherty Earth Observatory in Palisades, N.Y.
Colorado regulators have adopted a new rule requiring oil and gas companies to make public the chemicals they use for hydraulically fracturing wells in the state; a move that followed a lengthy set of meetings and negotiations between the industry and conservation groups.
This morning, Colorado regulators are expected to finalize new rules that will require oil and gas companies to make public the chemicals they use to hydraulically fracture wells. Much of the attention lately has been whether those “fracking” fluids that are mixed with sand and chemicals pose a risk to polluting ground water. But in Colorado there’s been far less scrutiny on just how much water the fracking process itself requires, until now.
Environmental groups and the oil and gas industry are at odds when it comes to a new rule on hydraulic fracturing. All sides agree that the chemicals used in fracturing should be made public, but they don’t agree on how and when. State regulators delayed a vote on the rule Monday evening and will deliberate more at a hearing next week in Greeley. KUNC’s State Capitol reporter Bente Birkeland has more.
