Updated at 4:07 p.m. Dec. 7 The Fort Bend County Hazardous Materials team responded to an oil well blowout Wednesday near Fort Bend Parkway Toll Road and Lake Olympia Parkway around 7:25 p.m., said Alan Spears, Fort Bend County's Deputy Emergency Management Coordinator. The county's hazmat unit remained on site until 10 p.m., monitoring the air quality in the surrounding area and checking readings every 15 minutes. He said that no hazardous chemicals were detected. Officials have reduced the oil leak and are in the process of capping it to stop it completely, Spears said Thursday. "It should be done by now," he said around 3:30 p.m. "But there is a pretty strong smell down there, though, and I'm afraid that's going to linger for a little while." Representatives from the Texas Railroad Commission and the Texas Commission on Environmental Quality were also present. "[TCEQ] are the ones that usually investigate that kind of thing," Spears said. The oil well is owned by Dallas-based company IWR Operating, LLC, Spears said. IWR Operating has contracted two companies to cap the well and to continue monitoring the air quality.
