LINCOLN, Neb. (AP) — Opposition to a planned wastewater well in northwest Nebraska has prompted lawmakers to introduce legislation.

Lawmakers took the rare step Thursday of suspending their rules so they could consider new regulations for wastewater wells.

A bill by Sen. Ernie Chambers of Omaha would require companies to disclose the chemicals in wastewater generated from oil and natural gas well production.

The Nebraska Oil and Gas Conservation Commission approved a well last month that would allow a Colorado company to discard such wastewater underground on a ranch in northwest Nebraska. The project drew opposition from landowners, environmental groups and others.

Ken Winston of the Nebraska Sierra Club says he understands the bill won’t pass this year, but it sends a message that lawmakers take the issue seriously.
