Chapter 173-201A WAC (Chelan UAA)

We are proposing amendments to chapter 173-201A WAC - Water Quality Standards for Surface Waters of the State of Washington.

We are proposing the following changes:

  • Changing WAC 173-201A-020 (Definitions)
  • Changing WAC 173-201A-440 (Use attainability analysis)
  • Changing the designated use for the Chelan River in WAC 173-201A-602 (Table 602—Use designations for fresh waters by water resource inventory area (WRIA)) and adding requirements for temperature and dissolved oxygen levels in the water that will only apply to the Chelan River

We are considering a change to the aquatic life designated use of salmonid spawning, rearing, and migration on the Chelan River using a use attainability analysis (UAA). A UAA is an approved water quality tool in Washington’s surface water quality standards (WAC 173-201A-440) and is used for removing or revising a designated use for a water body only if that use is not existing or attainable. A UAA is a scientific assessment of the physical, chemical, biological, and economic factors that may affect the attainment of the use.
