Groups call on BLM to act against Wyo. ozone

Cheyenne, Wyo. – Environmentalists are asking regulators to consider slowing down the pace of gas drilling in western Wyoming after several days of severe ozone pollution last winter.

Ozone levels in the Upper Green River Basin topped the highest levels in Los Angeles all last year. The ozone results from air pollution from gas drilling, which has picked up with the reviving economy.

Groups including the Wyoming Outdoor Council and Upper Green River Alliance are asking the U.S. Bureau of Land Management to take action including looking at slowing down gas development.

The BLM says a slowdown would be a last resort under the plans that guide drilling.

State regulators are meanwhile looking for the U.S. Environmental Protection Agency to set lower national limits for ozone pollution within the next few months.
