Review and Approval of State and Tribal Water Quality Standards - Alaska Rule
We require that water quality standards adopted by states and authorized tribes on or after May 30, 2000 must be approved by EPA before they can be used as the basis for actions, such as establishing water quality-based effluent limitations or total maximum daily loads (TMDLs), under the Clean Water Act.
