The 2022 Integrated Report (IR) assesses the quality of the surface waters in the state and identifies waterbodies that are not meeting water quality standards. These standards support the designated beneficial uses that protect water quality for drinking water, recreation, aquatic life, and agriculture. Waterbodies that do not meet one or more of their beneficial uses are classified as impaired in the IR and placed on the Clean Water Act 303(d) list.
The Draft 2022 Integrated Report was available for public comment October 29 to December 3, 2021. DWQ received comments on the Draft 2022 Integrated Report from five organizations, and DWQ responded to comments on February 4th before submitting a finalized version of the IR to EPA on February 8th, 2022. On March 8, 2022, EPA approved Utah’s 2022 303(d) list. You can find additional assessment information on EPA’s How’s My Waterway.
