PINEDALE, Wyo. (AP) — A state advisory panel has endorsed a proposal to reduce emissions from existing gas fields in western Wyoming.

The plan approved Wednesday by a Wyoming Department of Environmental Quality advisory board would reduce ozone pollution from gas fields in the Pinedale area. It also expands leak detection and repair requirements to compressor stations.

Efforts to address air quality in the Upper Green River Basin come two years after the U.S. Environmental Protection Agency found the region in violation of federal health standards.

The area is home to the Jonah and Pinedale natural gas fields.

The Casper Star-Tribune reports that the proposal now moves to the Environmental Quality Council. If passed by the EQC, the plan would then go to Gov. Matt Mead for final approval.
