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).
Resource. See also EPA's Interim Economic Guidance - Workbook on making a determination that a use cannot be met. See also, the Flexibilities module of the online course.
