SOUTH SIOUX CITY, Neb. — State regulators have revoked permits originally granted to a northeast Nebraska biogas plant that's been plagued with operational problems and odor complaints.
An official who presided over the state Environment and Energy Department case said Big Ox Energy had continually failed to comply with state regulations. The Denmark, Wisconsin-based company has 30 days to appeal the ruling. A company spokesman didn't immediately return an Associated Press message Thursday.
Several homeowners have filed lawsuits against the company and South Sioux City, saying the odors and gases backed up into their homes shortly after the plant opened.
