Designated Uses: Changing/Removing a Designated Use

Designated uses can be changed/removed with appropriate analysis and documentation. To support making such a change, a State or Tribe may be required to conduct a "use attainability analysis." In addition, a State/Tribe must provide an opportunity for a public hearing when changing/removing uses.

Key Point. A use attainablity analysis is a structured scientific assessment of the factors affecting the attainment of the use, which may include physical, chemical, biological, and economic factors as describe in Sec. 131.10(g).
