Powder River Assimilative Capacity

The Wyoming Environmental Quality Act gives authority to the Wyoming Department of
Environmental Quality to prevent, reduce and eliminate pollution; to preserve, and enhance the air, water and reclaim the land of Wyoming; and to plan the development, use, reclamation, preservation and enhancement of the air, land and water resources of the state. The Water Quality Division has adopted this policy consistent with the provisions of Wyoming Water Quality Rules and Regulations Chapters 1 and 2, the EQA and the federal Clean Water Act. DEQ may revise this policy as new information or scientific knowledge becomes available. 

The objective of this policy is to establish a mechanism, within the existing Wyoming Pollutant
Discharge Elimination System (WYPDES) regulatory framework, to allow discharges of coal bed natural gas (CBNG) produced water to the Powder River mainstem while providing the greatest level of assurance that the Wyoming and Montana standards for TDS and Sodium (Na) are protected.
