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.
