Water Quality Assessment Program


Previous Integrated Reports

The Integrated Report (IR) consists of the 303(d) Assessment Methodology list of impaired waters and the 305(b) report that summarizes the overall quality of Utah’s waters.

2012-2014 Integrated Report

The US EPA approved Utah’s 2012-2014 Integrated Report on November 30, 2015. As EPA’s final approval letter indicated, this was a "partial approval/ further review pending" action, the details of which were discussed in the approval letter and attachment.

2010 Integrated Report

USEPA approved Utah's 2010 Integrated Report on February 10, 2012 but deferred actions on Great Salt Lake and Kanab Creek-2. The final 303(d) list of impaired waters requiring a TMDL and delisted waters are presented as Part 3. Until the 305(b) portion of the Integrated Report (Part 2) is updated to match the final listings approved by USEPA, the tables in Part 3 should be consulted to determine the specific listing status of any waters.
