NewsOK: New disposal well delays As part of its response to the rise in earthquakes, the Corporation Commission has established a traffic light system for permitting wastewater disposal wells in areas of increased seismicity. Commission staff have directed companies to reduce volumes, cut disposal well depths or shut in some wells. But those directives were not laid out in formal orders voted on by the three-person commission. Last month, the commission delayed approvals on several new disposal wells...

EcoWatch: Two earthquakes registering at a 4.5 and a 4.4 magnitude shook frack-happy Oklahoma on Saturday, some of the strongest felt in the state this year. The stronger quake occurred just a few miles from the city of Cushing, which holds one of the largest crude oil storage facilities in the world. The recent quakes struck only a handful of weeks after the Oklahoma Corporation Commission (OCC), the states public utilities commission, shut down several disposal wells around Cushing and issued new regulations...

Associated Press: A moderate, magnitude-4.4 earthquake has shaken northern Oklahoma. It was one of the stronger temblors the earthquake-prone state has had this year. There were no initial reports of damage or injuries from Saturday mornings earthquake, which was 18 miles southwest of Medford and four miles deep.

Choy said this seems to...
