Wyoming deploys strategy to battle ozone

The Wyoming Department of Environmental Quality on Thursday made public its Ozone Strategy, a requirement of the federal “non-attainment” designation applied to the Sublette County area due to multiple wintertime ozone events that threatened human health. According to DEQ, the spikes in ground-level ozone were triggered by the presence of air pollutants from the Pinedale Anticline and Jonah natural gas fields.

Barring an objection from federal officials, EnCana Oil & Gas USA will be allowed to inject tainted “produced” water from its network of natural gas wells in the Moneta field into the Madison freshwater aquifer in central Wyoming. In recent years the landowner advocacy group Powder River Basin Resource Council (PRBRC) has advocated for more conservation of Wyoming’s groundwater — in particular taking aim at consumption and water quality degradation sometimes associated with energy development.
