Atmos Energy said it investigated hundreds of complaints about a mysterious odor in Dallas on Saturday.
In a statement, Atmos Energy spokesperson Jennifer Ryan said the odor complaints came from as far north as Interstate 635/LBJ Freeway and as far south as Woodall Rodgers Freeway in Downtown Dallas.
"After seven hours of door-to-door investigations, we have not been able to identify any natural gas leaks that would cause such a large number of odor complaints," Ryan said in a statement.
Dallas Fire-Rescue told NBC DFW that they found a strong chemical odor coming from the Mid-State United Recycling business at 1340 Manufacturing Street in Dallas. The smell originated from the plant recycling motor oil. The equipment to recycle the oil was shut down to cool off but it took hours for the smell to dissipate.
Atmos Energy urges anyone who smells natural gas inside their home or neighborhood to leave the area, call 911 or the Atmos Energy emergency phone number: 1-866-322-8667.
