Officials say Oklahoma Natural Gas crews have contained a propane leak that prompted a voluntary evacuation of a northern Oklahoma town.
ONEOK (WUN' oak) spokeswoman Megan Washbourne and Medford City Manager Dea Kretchmar said workers were still trying to cap the leak Sunday. Washbourne said they were waiting for a part to finish the job.
The leak began Tuesday at a fuel-storage plant owned by ONEOK, which is ONG's parent company. Medford residents were evacuated out of concern that the vapors could pose a fire risk if a pocket of propane ignited.
The Environmental Protection Agency said contractors planned to pump a brine and mud mixture into an underground well to stop the leak.
Kretchmar says residents who left their homes returned by Sunday.
