Jackson Hole Daily | April 3, 2012 : EPA to address unhealthy ozone levels in UGRV
By Cory Hatch, Jackson Hole News & Guide | Tuesday, April 3, 2012
The Environmental Protection Agency is expected to adopt rules to reduce air pollution from gas development in places such as the Upper Green River Valley. In recent years, pollution from energy development has prompted Wyoming Department of Environmental Quality officials to warn of high, unhealthy ozone levels for the Upper Green River Valley. Smog levels in rural communities like Pinedale have rivaled big cities such as Los Angeles.
“In Wyoming’s Upper Green River Basin, for 13 days last winter alone residents suffered ‘unhealthy’ ozone concentrations under EPA’s current standards, including days when the ozone pollution levels exceeded the worst days of smog pollution in Los Angeles.”
