EPA has delegated review of State/Tribal water quality standards to the EPA Regions.
A State/Tribe must involve the public in developing its standards.
EPA must approve a State/Tribe's submission within 60 days or disapprove it within 90 days and identify necessary changes.
If EPA disapproves part or all of a submission, the State/Tribe cannot implement those provisions in its program.
If the State/Tribe does not revise disapproved standards, EPA may promulgate Federal standards to replace the disapproved standards if necessary.
Following EPA approval, States/Tribes must review their water quality standards at least once every 3 years.
As necessary, the State/Tribe must hold a public hearing, adopt revised/new standards, and submit them to EPA for review.
- If no changes are needed, the State/Tribe still must submit the results of its review to EPA.
