PUBLIC NOTICE OF THE DRAFT 2026 INTEGRATED REPORT 303(d) ASSESSMENT
METHODS PUBLIC COMMENT PERIOD

PURPOSE OF PUBLIC NOTICE

The Utah Department of Environmental Quality, Division of Water Quality (DWQ) will be
assessing the waters of the state (e.g., rivers, streams, lakes and reservoirs). Under the Clean
Water Act, DWQ compiles all existing and readily available data every two years and assesses the
quality of the surface waters to identify 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, agriculture and Great Salt Lake. The Integrated Report is submitted
every two years for Environmental Protection Agency approval and includes the 305(b)
assessment report and the 303(d) list of impaired waters. The Assessment Methodology guides
how DWQ performs water quality assessments. To assist DWQ in making assessment decisions
we are soliciting comments on the draft 2026 Integrated Report 303(d) Assessment Methods.

PUBLIC COMMENTS

The 30-day public comment period for the Draft 2026 IR Assessment Methods will begin on
January 21, 2025 and end on February 20, 2025. All comments must be submitted using the
Public Comments Submission Form.
