The investigation into the River Road Wastewater Treatment Plant hazmat incident in Wichita Falls, which killed a city worker and left another injured, is ongoing.

A representative with the Occupation Safety & Health Administration said this incident is under the jurisdiction of the Texas State Health Department and was referred to their Austin office.

However, officials with the state health department said that they are not sure what authority the agency would have over this case, adding none of their programs are involved.

City officials have not released any new information about the investigation. Utilities Operations Manager Daniel Nix says it’s expected to be completed sometime this week.
