The U.S. Environmental Protection Agency is holding back the release of a report on earthquakes related to drilling and related operations,EnergyWire reports.
A team of EPA officials has been looking into concerns that deep injection wells – where wastewater from oil and gas drilling is disposed underground – have caused a spate of earthquakes in Ohio, Oklahoma, Texas, Arkansas and Colorado, says NPR's StateImpact Pennsylvania.
EnergyWire reports the team sent a final draft to EPA headquarters in January, but has not officially released it to the public five months later.
