"DENVER -- Colorado regulators looking at new air quality rules for oil and gas drillers are getting more time to set the rules."
"Colorado's Air Quality Control Commission originally aimed to have new proposed air-quality rules by November. At a regular meeting Thursday, the commission talked about extending negotiations on the air-quality rules until next February.
There was no immediate explanation for the delay. But in a Tuesday letter giving commissioners more time on the panel, Gov. John Hickenlooper called the work a 'significant undertaking.'"
