SIOUX CITY, Iowa (KCAU) – The City of Sioux City is no longer accepting wastewater from Big Ox Energy Company. The South Sioux City company’s wastewater permit with Sioux City has expired.
According to the City of South Sioux City, wastewater from the Roth Industrial park, previously passed to Sioux City by Big Ox, is now bypassing the Big Ox facility and being sent to Sioux City via a sewer main that was installed in 2017.
Big Ox had temporarily suspended operations in order to repair part of its facility.
The energy company is scheduled to appear before the Nebraska Department of Environmental Quality May 15. The agency has cited Big Ox for dozens of violations tied to air quality. At the hearing in Lincoln, the company will be asked to defend why it’s air quality permit should be renewed by the state.
