The DEQ Water Quality Division accepts comments on all permits authorized under a general permit for a period of 30 days, as provided for in W.S. 35-11-801(d).
Interested persons may mail or fax comments to the main Cheyenne office. The ‘Date’ column in the table below indicates the date the authorization was posted to the website. Comments must be received before 5:00 pm on the 30th day after the authorization was posted to the website. For example, comments for an authorization posted on 10/1/18 must be received by 5:00 p.m. on 10/31/18. DEQ does not accept emailed comments.
You may sort the table by posting date or search for the type of general permit, the county where the permit was issued, the permit number, or the name of the person or company to whom the permit was issued.

The Water Quality Division will present proposed revisions to Water Quality Rules Chapter 1, Wyoming Surface Water Quality Standards; and Chapter 2, Permit Regulations for Discharges to Wyoming Surface Waters to the Water and Waste Advisory Board at their June 13, 2024 meeting, starting at 9:00 a.m. The proposed revisions to Chapter 1 (1) fulfill the federal requirements at 40 CFR § 131.20, (2) restructure and align requirements with state law and federal law, regulations, and guidance; (3) revise designated uses and remove the designated use classification system; and (4) provide minor updates to specific water quality criteria. The proposed revisions to Chapter 2 (1) update references to the designated use classification system to reflect proposed revisions to Chapter 1; and (2) incorporate provisions related to fish toxicants, aquatic pesticides, and short-term sediment disturbance that Water Quality Division proposes to move from Chapter 1 to Chapter 2. More information is available at: http://deq.wyoming.gov/shwd/wwab/ under the “Upcoming Meeting” tab

The WQD Groundwater Program works to protect and preserve Wyoming’s groundwater by permitting facilities to prevent contamination, and investigating and cleaning up known releases.
The Groundwater Section includes the Underground Injection Control (UIC) program that permits the discharge of wastewater effluent, in-situ uranium processing waste and oilfield waste into subsurface geologic formations. These permits contain limits on the quality of the discharge based on aquifer or groundwater conditions and standards, and establish self-monitoring and reporting requirements for the permittees.
In addition to the UIC program, the Groundwater Section is responsible for developing groundwater classifications for exemption of aquifers impacted by in-situ uranium mining operations, overseeing groundwater investigations, implementing the division’s ambient groundwater monitoring program, administering the division’s groundwater data management system and overseeing the cleanup of legacy groundwater contaminated sites such as at historic spill sites and Department of Defense cleanup of Formerly Used Defense Sites (FUDS), such as the former Atlas Missile Sites in Laramie and Platte counties.
To request a groundwater classification for your project, submit the information to the WDEQ Groundwater section using the GW Classification Request Form.
The Federal Facilities team works with the Federal Government to clean up soil or groundwater contamination at active or decommissioned federal properties, such as the Atlas D Missile Site 4.
The GPC Program evaluates potential impacts to the groundwaters of the State by activities permitted at the local, state, or federal level.
The Know Your Well Program helps private well owners learn more about their drinking water wells and how to protect their water supply. If you have a question regarding private water wells, including permits and construction, please contact the Wyoming State Engineer’s Office at 307-777-6150.
The UIC Program is responsible for regulating and permitting the construction, operation and closure of facilities that dispose of or store non-hazardous materials below ground.

Aquifer Prioritization Project
This project developed a method to prioritize aquifers for groundwater monitoring based on their geology and potential contaminant sources.
Groundwater Vulnerability Mapping Project
GIS coverage maps and reports are available for each county. Please run the Autorun.exe in each county's zip file to access all data except the maps. To access map data, please download the shapefiles separately and import them into ArcMap.
Ambient Groundwater Monitoring Program
Pesticide Monitoring Program
Wyoming's Pesticide Monitoring Program is a cooperative monitoring effort between the Wyoming Dept. of Agriculture and the US Geologic Survey (USGS). Since 1995, the U.S. Geological Survey, in cooperation with the Wyoming Department of Agriculture, has been sampling groundwater in Wyoming. Sampling of surface water for pesticides began in 2006.
Groundwater and surface water data, maps, and reports, including fact sheets are available for each county.
