The Wyoming Department of Environmental Quality (DEQ) – Water Quality Division (WQD) recently received notice from the United States Environmental Protection Agency (USEPA) approving designated use changes of many low-flow stream channels in Wyoming for secondary contact recreation. 

As the third driest and least populated state in the U.S., Wyoming has thousands of low-flow channels and ditches that do not have sufficient water to support full body immersion and where people have limited contact with the water.

Secondary contact recreation includes activities such as wading and fishing that are not expected to result in immersion or similar levels of contact with the water. Previously, these low-flow channels were designated for primary contact recreation, which is intended to protect immersion, swimming, or similar water contact activities.

“These designated use changes more accurately reflect how the public uses and recreates in Wyoming streams,” said Lindsay Patterson, DEQ Surface Water Quality Standards Supervisor. 

A letter from the USEPA states:  

“The EPA approves the majority of Wyoming’s adopted SCR (Secondary Contact Recreation) uses as consistent with the CWA (Clean Water Act) and the EPA’s implementing regulations… We appreciate the efforts of WDEQ to address the EPA’s comments throughout the seven-year development of the UAA (Use Attainability Analysis) and resulting designated use changes.”

“We appreciate EPA and the Wyoming Conservation District’s assistance in developing this common sense approach to protecting our valuable water resources,” said Todd Parfitt, DEQ Director. “This is a great example of utilizing innovation and technology to provide efficient use of resources without reducing environmental protections.”

Parfitt added that DEQ will continue to work with interested stakeholders to modify recreational designated uses on a site-specific basis as appropriate. 

As stated in the USEPA letter:

“Designated uses are never “done” – they are regularly refined over time as new information becomes available… It is important that the public remains engaged in this ongoing use refinement process. Wyoming’s WQS (Water Quality Standards) allow “any person at any time” to petition the WDEQ for a designated use change.”

WQD submitted the designated use changes, rationale, and technical analysis to USEPA in November 2016. Information related to the analysis and EPA’s action can be found on DEQ’s website:
