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.

NOTICE: Effective November 23, 2021, all permits to be submitted for water distribution systems and/or sewage collection systems that are within the Cheyenne Board of Public Utilities (BOPU) district shall be submitted to the BOPU for approval.  BOPU contacts are Frank Strong or Bryce Dorr at (307) 637-6460,, or for additional information.


This page contains a variety of downloadable documents and information – including the Wyoming Water Quality Form and the Transfer of Ownership Form – Pertaining to Requirements for New Facilities Capable of Causing or Contributing to Pollution

Important Document Notes:

  • The Wyoming Water Quality Application Form must accompany every application. 
  • The Transfer of Ownership Form must be submitted upon change of ownership of any permitted facility. The permit will be transferred to the new owner and automatically includes any conditions established in the original permit. 

Coal Bed Natural Gas
  • The GPC Program issues permits and tracks compliance monitoring data for Coal Bed Natural Gas (CBM) impoundments to ensure groundwater quality.

    About CBM Impoundments

    The CBM industry uses unlined surface impoundments as one option for managing produced water. As the stored water soaks into the soil, contaminants in the water or already present in the soil can leach out and reach the groundwater below the impoundments. 

    The GPC Program issues permits and tracks compliance monitoring data for impoundments that overlay Class III (livestock) quality shallow groundwater. Additionally, the GPC Program provides compliance monitoring data, and data obtained while drilling more than 2,000 groundwater investigation boreholes, to the general public.

Pesticide Monitoring

For more information on the Wyoming Pesticide Monitoring Program and pesticide use in Wyoming, please visit the Wyoming Department of Agriculture Pesticide Program website.

Since 1995, the USGS has been monitoring pesticides in Wyoming groundwater.  For more information on the USGS Pesticide Monitoring Program and results by county, please visit the USGS WY/MT Water Science Center website.

The Groundwater Pollution Control (GPC) Program evaluates potential impacts to the groundwaters of the State by activities permitted at the local, state, or federal level.

GPC Program Manager: Nicole Twing 307-777-8275

The GPC Program assists federal agencies with National Environmental Policy Act (NEPA) reviews on projects like Pinedale Anticline and Moneta Divide. The GPC Program provides information and assistance to private well owners that have palatability issues or suspected contamination of their water, like the rural wells near Pavillion.

The GPC Program also reviews subdivision applications to ensure that the quality of water supply sources is adequate and that wastewater collection and treatment facilities will not impact groundwater.

The GPC Program also oversees sites where groundwater contamination already exists and cleanup is on-going, as well as sites where impacts may occur in the future. Groundwater monitoring tracks the extent and levels of existing contamination while remediation treats the groundwater to remove contaminants.

Monitoring wells and remediation projects must be permitted and constructed properly to ensure that the contamination is not spread further. Examples would be legacy GPC Program sites, which are primarily sites contaminated with petroleum hydrocarbons, or uranium mine cleanup sites. The GPC Program also issues permits for monitoring wells designed to detect potential contamination originating from coal bed methane (CBM) produced water impoundments that may reach shallow aquifers.
