When energy development happens on public lands, companies have to reclaim the land. That means restoring the landscape after it’s been disturbed. But exactly what’s required varies from one part of the state to another. Wyoming Public Radio’s Willow Belden reports that agencies are making those rules more consistent, in hopes of helping keep sage grouse off the endangered species list.
A new Bureau of Land Management report indicates that most of the groundwater contamination near Pinedale was not caused by the energy industry.
After petroleum products showed up in water wells in the Pinedale Anticline gas field in 2006, several agencies launched an investigation to figure out where the contamination was coming from. They concluded that some pollution occurred naturally, as gas seeped upward through geologic layers and into the groundwater. The report says other pollutants came from the process of drilling and installing water wells.
