City and gas company employees are working to repair a broken natural gas line.
City workers were digging in the alleyway Monday morning between the 100 block of E. Main St. and E. 10th Street to reach a water leak when they struck a four-inch natural gas line.
Ada firefighters, Ada Public Works employees and Centerpoint Energy employees are on scene working to resolve the situation.
Ada Assistant Fire Chief Danny Manuel said the public is not in any danger. Manuel said breezy winds are pushing the gas west down the alleyway where it is dispersing once it reaches Broadway Street.
"The amount of gas in the air is at a safe limit," Manuel said.
Manuel said there were no significant ignition sources in the alleyway.
Firefighters blocked the alleyway from auto and pedestrian traffic as a precaution. Employees with The Ada News evacuated the building as a precaution while firefighters checked the inside. Firefighters did not detect any measurable levels of natural gas in any nearby buildings.
Crews are working to run a bypass line to area businesses while repairs are made so no one goes without natural gas, although officials said one or two customers might be affected.
