Electronic Documents Submittal

In response to the Governor's request to limit contact and the move toward staff working remotely for the near future, the WDEQ Water Quality Division (WQD) has made electronic document submittal available. This includes permit applications, response to comments, reports, and other communications. Forms have been set up for individual WQD Sections (Watershed, WYPDES, Groundwater, Water/Wastewater), and a form is also available for general WQD submittals. Please choose the appropriate form from the list of links below to upload your documents. If submitted electronically, no hardcopy is required to be submitted unless you are contacted by a WQD Section Manager with a request to submit the hard copy. Please note that the Water Quality Division is unable to accept comments on documents in public notice via these forms. Please refer to the public notice for instructions on how to submit comments.

The Wyoming Department of Environmental Quality, Water Quality Division (DEQ/WQD) administers the NPDES program within the boundaries of the state (WYPDES program) except for on the Wind River Indian Reservation. This general permit was established to meet the court ordered mandate for pesticide applications to “waters of the U.S.” in Wyoming.

This general permit for major pesticide applications applies to pesticide applications that exceed the size thresholds established for the various pesticide use categories. This permit does not apply to pesticide applications on waters impaired for a specific pesticide or its degradates, however, the permit may be used for the application of other types of pesticides with different degradates than those listed in the impairment. The effluent limits established in this permit are based upon Chapters 1, 2, and 4 of the Wyoming Water Quality Rules and Regulations.
