Energy companies delay work amid Wyo. ozone spike

PINEDALE, Wyo. – Three energy companies are postponing some
natural gas work in western Wyoming in hopes of reducing air
pollution amid elevated ozone levels.
Shell spokeswoman Darci Sinclair told the Casper Star-Tribune in
Saturday's editions that Shell, QEP and Ultra Petroleum took the
steps as state officials said ozone levels in Sublette County
exceeded federal air-quality standards.
The state Department of Environmental Quality and Wyoming
Department of Health issued an ozone alert for the area effective
Saturday. They say conditions may allow ozone to develop for
several days.
A meeting is planned Monday among the Department of
Environmental Quality and energy companies to see what can be done
to reduce emissions during ozone advisories.
