Federally Promulgated Water Quality Standards for Specific States, Territories, and Tribes
In instances when state-specific water quality standards have not been developed or approved by EPA, the Agency will propose and/or promulgate standards for a state until such time as the state submits and EPA approves their own standards.
The lists below do not include states, territories or tribes covered only by federal standards applicable to multiple states, such as the Bacteria Rule for Coastal and Great Lakes Waters, and the National Toxics Rule.
- District of Columbia
- New Jersey
- New York
- Rhode Island
- Washington State
- West Virginia
