Clean Water

Wyoming is home to clean, cold rivers and streams that support world class native trout fisheries.

These waters provide agricultural irrigation, wildlife habitat, support for guiding and outfitting industries, and ensure that residents have safe drinking water and access to year round recreation. That’s why we advocate for Wyoming’s water quality.

We are particularly concerned about the Department of Environmental Quality’s proposal to allow Aethon Energy to discharge more than 8 million gallons per day of contaminated oil and gas wastewater into Boysen Reservoir and the Wind and Bighorn rivers. Boysen is a recreational hotspot, and the Bighorn is a Class 1 Blue Ribbon trout stream. Although not disclosed in the permit, this produced water may contain chemicals used in fracking — chemicals that could harm fish, wildlife, and human health. The draft permit allows Aethon to dump more than 2,100 tons of total dissolved solids — including 719 tons of chloride — into Boysen Reservoir each month.

We joined conservation organizations, tribes, municipalities, and downstream irrigators to ask the state to extend the public comment period on this proposal, which DEQ granted. The comment period has been extended to July 5.

Wyomingites care about our water quality, our wildlife, and our outdoor recreation. We will continue to analyze the many water quality impacts of this project. 

Join the Outdoor Council in telling DEQ “Don’t Poison Boysen!”

The Wyoming Department of Environmental Quality is preparing to issue a discharge permit to Texas-based Aethon Energy to dump up to 8.27 million gallons per day of oilfield wastewater into tributaries of Boysen Reservoir. We need your help to persuade the DEQ to tighten pollution limits in the permit and consider better alternatives to Aethon’s proposal.

The Bureau of Land Management has prepared a draft Environmental Impact Statement for the Moneta Divide Project — a proposal to drill up to 4,100 more wells in the central Wyoming oil and gas field. Click here to read the BLM’s draft analysis of the project’s environmental impacts.

WOC is Working for Clean Water

Right now, we have an opportunity to weigh in on a comprehensive review of Wyoming’s water quality standards, and to urge the Department of Environmental Quality to adopt the most protective standards available to protect water-based recreation, human health, and aquatic life.
