Oklahoma Gas & Electric continues to collect and contain mineral oil that spilled from a ruptured transformer on June 1 near Fort Smith, a spokesman for the company said.
“We feel like we’ve recovered a majority of the oil,” spokesman Rob Ratley said.
Mineral oil leaked from a failed transformer at a substation into Mill Creek. The transformer held 16,000 gallons of the nontoxic substance, which is used as a cooling fluid.
The utility is working with the Environmental Protection Agency and the Arkansas Department of Environmental Quality, he said.
OG&E Electric Services continues to investigate the cause of the failure, said a spokesman for the EPA.
The utility has not set an ending point for the response, Ratley said.
