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 December 12, 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 Groundwater Pollution Control (GPC) Program evaluates potential impacts to the groundwaters of the State by activities permitted at the local, state, or federal level.
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.

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.
