Basic Course: Key Concepts
Summary
- 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.
