Energy companies operating near Pinedale will soon have to retrofit their older equipment to curb emissions.
Natural gas development in the Pinedale Anticline gas field has caused air pollution, to the extent that the area violates federal air quality standards. The Wyoming Department of Environmental Quality has already imposed limits on emissions from new equipment. But until now, older equipment that was already in place was exempt from those standards. DEQ Air Quality Administrator Steve Dietrich says that needs to change.
