Module 2. Designated Uses

« Page 13 of 14 »

  • States/Tribes have primary responsibility for determining the uses of their water bodies.

  • Designated uses are waterbody goals that may or may not be currently attained.

  • Existing uses for a water body are those "actually attained" or that have been since 1975.

  • The Water Quality Standards regulations provide a "rebuttable presumption" that the CWA Section 101(a) goal uses are attainable.

  • States/Tribes may choose to subcategorize their uses to more precisely describe the desired condition.
