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

Class VI Carbon Capture, Utilization & Storage (CCUS) refers to the process in which carbon is captured from industrial processes and either utilized by turning the carbon into a new product or stored by injecting the carbon into a storage site, usually underground in a geologic formation.
For more information on how to apply for a Class VI permit, please review the Class VI Injection Wells and Facilities Underground Injection Control Program Informational Program Packet located in the ‘Forms and Guidance’ tab above.

Wyoming Environmental Quality Act and Industrial Development Information and Siting Act (2020 Edition) 35-11-103:
Carbon sequestration permit requirements and Unitization are outlined in 35-11-313 through 35- 11-317
Water Quality Rules Chapter 24. Section 2(v) “Geologic sequestration project” means an injection well or wells used to emplace a carbon dioxide stream into an injection zone for geologic sequestration. It includes the subsurface three-dimensional extent of the carbon dioxide plume. associated pressure front. and displaced fluid. as well as the surface area above that delineated region.
Section 1421 of the Safe Drinking Water Act (SOWA) requires the US EPA to develop UIC program requirements that protect underground sources of drinking water. Primary enforcement authority, often called primacy, refers to state, territory or tribal responsibilities associated with implementing US EPA approved UIC programs. Primacy programs are established under Section 1422 and 1425 of the SDWA. Wyoming received primacy over Class I through V in 1983. The Wyoming Department of Environmental Quality received primacy over Class VI wells on September 3. 2020. Wyoming is one of two states to have received primacy for implementing the Class VI program; the other is North Dakota.
